Item 11.a. - Page 1 CITY COUNCIL CONSIDERATION OF WATER SUPPLY STRATEGY AND AMENDMENTS TO CONSULTANT SERVICES AGREEMENTS FOR THE NORTHERN CITIES MANAGEMENT AREA WORK PROGRAM JUNE 10, 2014 PAGE 2 IMPACT ON FINANCIAL AND PERSONNEL RESOURCES: Staff’s recommendations are designed to achieve the City’s water conservation goals by 2020, which provides an implementation period of 5.5 years. Total expenditures projected for this period are as follows: Program FY 2014-15 Total Turf Removal Program $60,000 $330,000 Washing Machine Rebates $8,000 $44,000 Smart Irrigation Controller Program $8,000 $44,000 Landscape Irrigation Retrofit $6,000 $33,000 Plumbing Retrofit Program $52,050 $286,275 System Water Loss Mitigation $25,000 $100,000 City Landscape Irrigation $40,000 $200,000 Water Survey Program $20,000 $110,000 Public Education Campaign $100,000 $410,000 Total $319,050 $1,557,275 It is proposed to budget $100,000 annually the first two years for public education and then decrease it to $60,000 annually. System water loss mitigation is proposed to be funded over a four-year period and the City drought tolerant landscape improvements over a 5-year period. Therefore, total expenditures proposed for FY 2014-15 are projected to be $319,050. It is proposed to fund the program from the following projected revenues: Existing Water Mitigation Fee Funds $190,000 Future Projected Water Mitigation Fee Revenue $275,000 Annual Funds Programmed in Water Fund for Conservation $275,000 Funding Available from Expiration of OCSD Water Purchase Agreement $825,000 Total $1,565,000 The City’s projected share of costs for studies proposed by the NCMA TG to better manage the area’s water supply and develop a project and overall strategy to protect the City’s groundwater supply from seawater intrusion are as follows: NCMA Total City Share (31.92%) Groundwater Model $750,000 $239,400 Monitoring Well $15,000 $4,788 Salt and Nutrient Management Plan $250,000 $79,800 Groundwater Storage $250,000 $79,800 Management Agreement $100,000 $31,920 Inter-agency Mutual Aid $25,000 $7,980 Supplemental Water Strategy $150,000 $47,880 Item 11.a. - Page 2 CITY COUNCIL CONSIDERATION OF WATER SUPPLY STRATEGY AND AMENDMENTS TO CONSULTANT SERVICES AGREEMENTS FOR THE NORTHERN CITIES MANAGEMENT AREA WORK PROGRAM JUNE 10, 2014 PAGE 3 Outreach to Agricultural Community $6,000 $1,915 Regional UWMP $170,000 $54,264 Water Shortage Contingency Plan $50,000 $15,960 Optimization of Surface Water Supply $100,000 $31,920 Total $1,866,000 $595,627 The bulk of the studies are projected to be completed over a similar 5-year period. The cost sharing methodology was based on the percentage of groundwater allocated through the settlement agreement. It is proposed to fund these costs from the Water Availability Fund, which are revenues designed to ensure the continued reliability of the City’s water supply. There is currently a balance of $1.6 million in this fund. Therefore, the total appropriation recommended for FY 2014-15 is $914,677. FY 2014- 15 expenditures are proposed to be funded from the following sources: Existing Water Mitigation Fee Funds $119,050 Annual Funds Programmed in Water Fund for Conservation $50,000 Funding Available from Expiration of OCSD Water Purchase Agreement $150,000 Water Availability Fund $595,627 Total $914,677 All expenditure recommendations have been included in the year-end budget for Council approval of the appropriations. These proposed expenses may however be distributed over multiple fiscal years and some of the above requested funds may be rolled over into future budget years. The recommendations will result in a substantial commitment of staff resources. However, addressing water supply is one of the City’s priorities identified in the Critical Needs Action Plan. It is also important to note that the other participating NCMA agencies, City of Grover Beach, City of Pismo Beach and the Oceano Community Services District, will be requested to participate in the financing of the NCMA management projects. BACKGROUND: The City’s long-term water supply was identified as a significant issue during development of the City’s 2001 General Plan Update. At the August 24, 2004 meeting, the City Council reviewed a Water Alternatives Study identifying 17 alternatives for Council consideration. Since that time, a number of studies have been completed on the following alternatives:  Nacimiento Water project  Price Canyon oil field recycled water  Desalination  Recycled water Item 11.a. - Page 3 CITY COUNCIL CONSIDERATION OF WATER SUPPLY STRATEGY AND AMENDMENTS TO CONSULTANT SERVICES AGREEMENTS FOR THE NORTHERN CITIES MANAGEMENT AREA WORK PROGRAM JUNE 10, 2014 PAGE 4  Raising of the spillway at the Lopez Lake dam  Acquisition of State water  Lopez Spillway Raise study The South San Luis Obispo County Sanitation District contracted with the Wallace Group in 2009 for a comprehensive Water Recycling Study, which was an update to an original study prepared in 2001. Additional studies were prepared in 2010 to assess the potential for a distribution system from either the South County Sanitation District or Pismo Beach wastewater treatment plants to potential users. The limited number of user sites has been a barrier to making installation of a distribution system for turf irrigation cost effective and worthwhile. As a result, recent focus has been on determining the feasibility of using recycled water for groundwater recharge through crop irrigation, stream augmentation, or recharge by injection or surface spreading. Among other recommendations, the report proposed to: Conduct additional feasibility studies to address hydrogeologic issues relative to aquifer recharge. This study is needed to define the locations suitable for injection or spreading basins, and to consider well locations for possible seawater barrier protection. The original strategy was to pursue grant funds for these efforts, which has been unsuccessful. In order to make progress on this effort, it is now currently proposed to locally fund necessary feasibility studies and pursue grants for construction of any recommended project deemed feasible. In 2008, it was determined the City had utilized 99% of its water entitlements. At the August 12, 2008 meeting, the City Council approved a Resolution declaring a “severely restricted water supply condition.” Mandatory conservation measures were enacted. These measures were later made permanent in 2010. Meanwhile, the City’s water conservation program and tiered rate structure were expanded. In January 2009, the City entered into a 5-year temporary water purchase agreement with the Oceano Community Service District (OCSD), which expired in March of 2014. Well #10 was completed in 2011 and Well #11 is currently in design and scheduled for completion by the end of 2014. In 2009, low groundwater levels and high chloride concentrations from water quality tests of one of the sentry wells located along the coast gave indications of incipit seawater intrusion. At the November 10, 2009 meeting, the City Council adopted an Interim Urgency Ordinance establishing a development moratorium. The moratorium was extended at the December 8, 2009 and April 13, 2010 meetings. The moratorium Item 11.a. - Page 4 CITY COUNCIL CONSIDERATION OF WATER SUPPLY STRATEGY AND AMENDMENTS TO CONSULTANT SERVICES AGREEMENTS FOR THE NORTHERN CITIES MANAGEMENT AREA WORK PROGRAM JUNE 10, 2014 PAGE 5 later expired in 2010. The State of California also enacted the Water Conservation Act 2009, which required a reduction of 20% in per capita water use by the year 2020. In June 2010, staff presented a water analysis and strategies to the City Council, which identified a projected need of approximately 400 additional acre feet of water to meet the community's needs when it reaches its buildout population under the current General Plan. It was agreed to address these needs by expanding water conservation efforts, seeking purchase of State water, and to continue working on the potential for a water recycling project in the future. The City Council directed staff to prepare a ballot measure for the June 2012 election to enable purchase of State water. However, due to a number of concerns, this was later delayed to obtain additional data and further study of other alternatives. In 2009, a technical group of the NCMA jurisdictions was formed to meet on a monthly basis to coordinate water sampling and preparation of an annual report required by the Court’s decision in the Santa Maria Groundwater Basin Adjudication. Additionally, the group assumes the technical work in planning for the groundwater sub-basin and overall area water supply. The Technical Group includes representatives from Arroyo Grande, Grover Beach, Pismo Beach and OCSD. A consultant has also been jointly contracted by the agencies to help coordinate these efforts. On January 17, 2014, Governor Brown issued a proclamation declaring a Drought State of Emergency for the State of California. Local urban water suppliers and municipalities are called upon to implement their local water shortage contingency plans immediately in order to avoid or forestall outright restrictions that could become necessary later in the drought season. The City implemented its contingency plan and permanent mandatory conservation measures in 2010. Additionally, a statewide water conservation campaign calls on Californians to reduce their water usage by 20 percent. Local water agencies are also required to update their legally required urban and agricultural water management plans to help plan for extended drought conditions. The City’s plan is up to date and is required to be updated again in 2015. Staff has drawn two conclusions from the severity of the current drought. First, the likelihood of identifying agencies interested in selling permanent water supply to the City is increasingly improbable. Second, protecting and securing the City’s existing water supply should be the highest priority since having dependable water sources is more valuable than a larger water supply that is unreliable when most needed. As a result, staff’s recommendations are designed to accomplish the following goals: Item 11.a. - Page 5 CITY COUNCIL CONSIDERATION OF WATER SUPPLY STRATEGY AND AMENDMENTS TO CONSULTANT SERVICES AGREEMENTS FOR THE NORTHERN CITIES MANAGEMENT AREA WORK PROGRAM JUNE 10, 2014 PAGE 6  Meet the City’s future projected water demand of its buildout population by; o Meeting the reduction in per capita use as prescribed in the Water Conservation Act of 2009; o Proceeding with work necessary to develop a recycled water project that can be used to prevent seawater intrusion in order to provide long-range protection of the City’s groundwater supply; and  Ensure water use efficiency and drought protection through regional conjunctive use, storage and management of surface and groundwater supplies. ANALYSIS OF ISSUES: Water Supply and Demand Table 1 below shows the current and projected water supply through 2030. Table - 1.

The California Department of Finance provides more updated population data and shows that the City decreased its population by 0.5% between 2013 and 2014 (17,415 to 17,334). Current estimates by the San Luis Obispo Council of Governments (SLOCOG) in their 2040 Regional Growth Forecast (August 2011) project the City’s population to be approximately 18,407 residents by 2020, based upon an annual growth rate of 0.72%. The City’s 2001 General Plan estimates that a buildout population of 20,000 will be reached by 2023. Given that the City has not experienced a continuous 1% growth rate as estimated in the General Plan, buildout will likely be later than 2023. Item 11.a. - Page 7 CITY COUNCIL CONSIDERATION OF WATER SUPPLY STRATEGY AND AMENDMENTS TO CONSULTANT SERVICES AGREEMENTS FOR THE NORTHERN CITIES MANAGEMENT AREA WORK PROGRAM JUNE 10, 2014 PAGE 8 Overview of City’s Annual Water Reduction Goals Figure 1 shows the projected per capita use production to meet the State water conservation reduction goal: The City Council adopted a Water Conservation Program in May of 2003. Phase I of the program began in April of 2004, which focused on retrofitting existing residential plumbing with low flow fixtures. In 2008, the City Council appropriated $50,000 from the Water Neutralization Fund to initiate water conservation rebate programs for turf removal, high efficiency washing machines and smart irrigation controllers. Staff recommends that a landscape irrigation retrofit program, system water loss mitigation project, City landscape irrigation retrofit program, and a water use survey program be added to the water conservation strategy. An overview of these programs is discussed below. Item 11.a. - Page 8 CITY COUNCIL CONSIDERATION OF WATER SUPPLY STRATEGY AND AMENDMENTS TO CONSULTANT SERVICES AGREEMENTS FOR THE NORTHERN CITIES MANAGEMENT AREA WORK PROGRAM JUNE 10, 2014 PAGE 9 Water Conservation Recommendations Below is a pie chart outlining the proposed Water Conservation Strategy to meet the target of 149 gallons per resident per day by 2020. Summary of Water Conservation Programs  Plumbing Retrofit Program (existing)  Cash for Grass Rebate Program (existing)  Water Efficient Washing Machine Rebate Program (existing)  Smart Irrigation Controller and Sensor Program (existing)  Large Area Irrigation Retrofits (existing)  Landscape irrigation retrofit program (proposed)  Public Education Program (proposed)  System Water Loss Mitigation Project (proposed)  City Landscape Irrigation Retrofit Program (proposed)  Water Use Survey Program (proposed) Item 11.a. - Page 9 CITY COUNCIL CONSIDERATION OF WATER SUPPLY STRATEGY AND AMENDMENTS TO CONSULTANT SERVICES AGREEMENTS FOR THE NORTHERN CITIES MANAGEMENT AREA WORK PROGRAM JUNE 10, 2014 PAGE 10 The Plumbing Retrofit Program replaces old, high water-use fixtures for residential units built prior to 1992. All parts and labor required for the retrofit are provided free of charge. The retrofit includes replacing the following fixtures:  Toilets – replace with ultra low-flow 1.6 gallons per flush (as of January 1, 2014 the requirement is 1.28 gallons per flush). Cost is $235 - $290 per toilet.  Indoor Faucets – install aerators designed for 2.0 gallons per minute. Cost is $5 per faucet.  Showerheads – replace with 2.5 gallons per minute. Cost is $13 per showerhead.  Pressure Regulator – inspect and adjust or install new regulator not to exceed 80 pounds per inch (pi). Cost is $135 for new pressure regulator. This program is voluntary; however, in February 2005 the City Council adopted an ordinance implementing a mandatory plumbing retrofit program upon the change of ownership of any real property. The seller must retrofit the property’s plumbing fixtures to meet the criteria of low-water use. Staff estimates that his program saves 7.5 AFY of water. The goal is to retrofit 150 homes per year. Staff recommends that this program continue with no changes. The Cash for Grass Rebate Program provides a financial incentive for homeowners and businesses to remove existing turf and replace it with a less water-intensive landscape. The goal of the program is to encourage a permanent reduction in the amount of water used for landscaping. The City currently pays $0.50 per square foot of turf removed. The minimum amount of turf to be removed must be 250 square feet ($125) and the maximum amount of turf to be reimbursed is 5,000 square feet ($2,500). To date, 121 turf removal projects have been completed removing 14,716 square feet (3.23 acres) of grass. Staff estimates that this program saves 3.3 acre feet per year (AFY) of water. In an effort to increase participation, staff recommends increasing the rebate from $0.50 a square foot to $1.00. The goal is to achieve 50 turf replacement projects per year. Staff also recommends increasing the minimum amount of turf removed from 250 to 500 square feet as there has been limited water savings with the smaller turf removal projects. The Water Efficient Washing Machine Rebate Program provides a rebate of $100 for Consortium for Energy Efficiency (CEE) Tier 2 washers and $150 for CEE Tier 3 washers. On average, a high high-efficiency washer uses 20% less energy and 35% less water than regular washers, which can save up to 5,250 gallons per year per household. To date, 102 rebates have been issued. Staff estimates that 0.8 AFY of water is saved with this program. The goal is to replace 40 washers per year. Staff recommends that only CEE Tier 3 washers be rebated since they save the most water, and the rebate amount be increased from $150 to $200 as an added incentive. Item 11.a. - Page 10 CITY COUNCIL CONSIDERATION OF WATER SUPPLY STRATEGY AND AMENDMENTS TO CONSULTANT SERVICES AGREEMENTS FOR THE NORTHERN CITIES MANAGEMENT AREA WORK PROGRAM JUNE 10, 2014 PAGE 11 The Smart Irrigation Controller and Sensor Program provides an irrigation audit with recommendations for system improvements and a smart controller with weather-based sensor technology to replace older controllers for residential properties. The City pays up to $300 for a new controller per residence. The City contracts with Sprinkler King, Inc. to conduct the water audits and provide the controllers to qualifying participants. To date, 65 water audits have been performed with new controllers installed. The estimated water savings is 0.9 AFY with this program. The goal is to achieve 20 installations per year. Staff recommends that this program continue with no changes. Since 2009, the City has contributed to Large Area Irrigation Retrofits for commercial, institutional and homeowner association (HOA) water users. To date, the City, with the assistance of Sprinkler King, Inc., have retrofitted the following properties:  Strother Park  St. Patrick’s School  Sunrise Terrace Mobil Home Park  Paulding School  Ocean View School  Vista Del Mar HOA  Wildwood Ranch HOA  Five Cities Center  Kmart Center  Cemetery District  Rancho Grande Park It is estimated that 17.39 AFY is saved from the Strother Park, Paulding School, Ocean View School, Cemetery District and Rancho Grande Park retrofits (audits have not been completed for the other properties). Staff recommends that this program continue with no changes. The goal is to contact other large commercial, institutional and HOA water users to encourage participation in the program. The proposed Landscape Irrigation Retrofit Program includes retrofitting outdated spray heads and drip emitters for existing residences. Sprinkler King, Inc. has conducted 60 residential irrigation audits for the City and provided information on the average sized landscape retrofit. This includes replacing 25 sprinkler heads with MP rotators and/or drip irrigation emitters. The estimated water savings is 30% per retrofit. The cost for an average residential irrigation retrofit using MP rotators and emitters, less labor and tax costs, is $200. The estimated water savings is 0.8 AFY. The goal is to achieve 20 installations per year. Staff recommends this program be added as a new water conservation rebate program. Item 11.a. - Page 11 CITY COUNCIL CONSIDERATION OF WATER SUPPLY STRATEGY AND AMENDMENTS TO CONSULTANT SERVICES AGREEMENTS FOR THE NORTHERN CITIES MANAGEMENT AREA WORK PROGRAM JUNE 10, 2014 PAGE 12 The proposed Public Education Program would involve hiring a consultant to design an extensive public education marketing campaign to encourage water conservation citywide. The marketing campaign is proposed to include, but not be limited to, development of press releases, advertisements, brochures, posters, billboards and video segments for the government access channel. The estimated total water savings is approximately 23 AFY. The proposed System Water Loss Mitigation Project will provide funding for a leak detection survey of the City’s water distribution system. Approximately seven percent (7%) of the water produced or delivered to the City is lost through leaks, inaccurate water meters or other unaccounted for water loss. Most water distribution systems have typical water losses of between 5% and 10%. Staff believes that through a comprehensive leak detection survey and repair of identified water loss locations, a 2% reduction to the City’s water system loss is attainable. A 2% reduction in water loss will generate a water savings of approximately 12.4 acre-feet. The proposed City-owned Property Landscape Irrigation Retrofit Program will provide funding for a comprehensive effort to reduce water use at City parks and landscape areas. This program will involve turf removal and irrigation retrofit projects. Turf removal areas will be re-landscaped with drought tolerant landscaping. Arroyo Grande in Bloom will be consulted on the re-landscaping designs and final design plans are proposed to be reviewed by the Arroyo Grande Parks and Recreation Commission. This proposed program is also important because beginning in FY 2014-15, water costs for City parks and landscape areas will be charged to the General Fund. Previously water costs were borne by the Water Fund. It is estimated that this program will generate a water savings of approximately 14 acre-feet. The proposed Water Use Survey Program is proposed to involve the use of existing Public Works Utilities Division staff to conduct water use surveys at targeted residential and commercial properties. If approved, funding for this program will be utilized to hire a temporary employee to back-fill the duties of one current Utilities Division employee. During the five and one-half year program, staff’s goal will be to contact all of our water system customers to arrange for a Water Use Survey. However, the high use customers will be targeted first. Following the Water Use Survey, customers will be referred to existing water conservation programs and other necessary corrections that will help the customer reduce water use. It is estimated that this program will generate a annual water savings of approximately 2.5 acre-feet in addition to increasing participation in other incentive programs. Item 11.a. - Page 12 CITY COUNCIL CONSIDERATION OF WATER SUPPLY STRATEGY AND AMENDMENTS TO CONSULTANT SERVICES AGREEMENTS FOR THE NORTHERN CITIES MANAGEMENT AREA WORK PROGRAM JUNE 10, 2014 PAGE 13 Projected Water Savings: Table 3 depicts the projected savings and costs for the various water conservation programs and efforts stated above based upon targets established for each proposed measure. The overall recommendations are designed to demonstrate how the City can accomplish and fund the efforts necessary to reach the total water use savings target. Table 3.

Therefore, in addition to other practical issues, water conservation measures clearly provide the most cost efficient approach to addressing water needs. Implementation Strategies The City’s Water Conservation Team staff meets regularly to implement the work program. Existing programs will be augmented to integrate new goals, including issuing Request for Proposals for the education program and system water loss efforts. Staff will monitor the program and provide updates to the City Manager. NCMA Efforts Annual Reports for the NCMA are prepared pursuant to the requirements of the Stipulation and 2008 Judgment for the Santa Maria Groundwater Basin Adjudication. The Annual Report provides an assessment of hydrologic conditions for the NCMA based on data collected during the calendar year of record. As specified in the Judgment, the NCMA agencies are to conduct groundwater monitoring in the NCMA, and collect and analyze data pertinent to water supply and demand, including:  Land and water uses in the basin;  Sources of supply to meet those uses;  Groundwater conditions (including water levels and water quality);  Amount and disposition of developed water supplies; and  Amount and disposition of other sources of water supply in the NCMA. Since April 2009, the NCMA TG has coordinated the data compilation and analysis required in the annual report for court submittal. The most recent report was submitted in April, 2014 (Attachment 1). Findings from the report include:  Substantial lower than average rainfall;  A significant drop in water levels from 2012;  Data indicating that water levels are sensitive to municipal pumping irrespective of agricultural pumping;  In 2013, the NCMA agencies pumped 1,423 AF out of a total allocation of 4,330 AFY, which equates to approximately 33% of the total allocation;  Groundwater pumping in the NCMA area accounts for approximately 39% of total water use;  Excessive pumping on the Mesa has created a landward gradient that eliminates the historic recharge volume of subsurface inflow into the NCMA (thereby reducing the yield of the aquifer), and creates conditions favorable to seawater intrusion in the NCMA and Nipomo Mesa Management Area; and  Continued average water level values are below an established index and indicate a potential environment for increased risk of seawater intrusion. Item 11.a. - Page 14 CITY COUNCIL CONSIDERATION OF WATER SUPPLY STRATEGY AND AMENDMENTS TO CONSULTANT SERVICES AGREEMENTS FOR THE NORTHERN CITIES MANAGEMENT AREA WORK PROGRAM JUNE 10, 2014 PAGE 15 This last factor is important considering effects of any increased pumpage related to cutbacks in surface water deliveries (state water and Lopez surplus water) because the index level is similar to the level seen in 2008-2009 just prior to observing the elevated chloride concentrations in one of the sentry wells. Data analysis indicates there is a probable lag time before signatures of seawater intrusion would be observed after a period of several months of low water levels. A summary of the annual report from the consultant will be presented at the Council meeting. The NCMA work program has evolved to increase and augment water sampling by the rehabilitation of wells, increased sampling locations, the addition of transducers, the coordination of data with the county sampling program and the Nipomo Mesa Management Area Technical Group. The work program for the 2014 NCMA Annual Report includes the scope of work for the monitoring and reporting program by Fugro Consultants and staff extension services by Water Systems Consulting (WSC). The work program for Fugro is substantially the same as that approved for 2013, with the additional analysis and monitoring included as recommended by the NCMA TG. WSC’s scope of work for ongoing support services to the NCMA TG includes agency and contract coordination and administration, along with providing necessary technical analysis. Additionally, the NCMA TG has helped secure successful grants to complete additional studies. Data that is being developed is intended to support an eventual groundwater model that is critically needed to both inform and enable prediction of groundwater conditions and facilitate better management and conjunctive use of the area’s water resources. Grant efforts nearing completion include the Integrated Regional Water Management (IRWM) Planning Grants to improve the characterization of the NCMA and Nipomo Mesa Management Area (NMMA), portions of the Santa Maria Groundwater Basin, and a regional recycled water study. One important step taken by the NCMA TG was to establish the early indicator for seawater intrusion based upon historical data and referred to as the “deep well index” that is described in the annual report. Additional data was collected on May 5, 2014 that showed that the value of the deep well index had been declining at an average daily rate of about 0.24 feet between mid-April and early May. The NCMA TG has directed consultants to continue an increased data download and analysis to better observe any potential indicators of seawater intrusion. From a long-term perspective, what makes this an even more significant concern is the fact that the NCMA jurisdictions are only pumping approximately one-third of their entitlements. Therefore, decreasing groundwater levels not only provide a short-term issue, but brings into question whether current allocations of groundwater are realistic Item 11.a. - Page 15 CITY COUNCIL CONSIDERATION OF WATER SUPPLY STRATEGY AND AMENDMENTS TO CONSULTANT SERVICES AGREEMENTS FOR THE NORTHERN CITIES MANAGEMENT AREA WORK PROGRAM JUNE 10, 2014 PAGE 16 on a long-term basis when jurisdictions approach full use of their entitlements. The proposed groundwater model discussed further below will help address these concerns. NCMA Strategic Plan A key water supply planning and management activity started in late 2013 by the NCMA TG is the initiation of joint Strategic Planning efforts for the purpose of providing a framework for identifying common water resource planning goals and objectives and to establish a 10-year work plan for implementation of those efforts (Attachment 2). Several key objectives have been identified, including water supply reliability, increased outreach, and basin management. The mission statement is set forth below. Preserve and enhance the sustainability of water supplies for the Northern Cities Area by:  Enhancing supply reliability  Protecting water quality  Maintaining cost-effective water supplies  Advancing the legacy of cooperative water resources management Several strategic initiatives were developed, prioritized, ranked and ultimately included in an implementation plan and proposed budget. Key efforts include:  Intertie Plan and Inter-agency Mutual Aid requirements – this effort includes developing an intertie model and evaluating upgrades to connect pipes and develop pipe capacity to deliver water between agencies as well as necessary mutual aid agreements in order to protect against vulnerabilities due to drought or loss of specific water supplies.  Water Shortage Contingency Plan - this effort includes coordinating urban water management plans for the northern cities and developing a coordinated plan of action to respond to a severe shortage condition within the NCMA.  Salt and Nutrient Management Plan –this study will shortly be required by the State and will provide data for the development of a groundwater model. The current grant study nearing completion (the Santa Maria Ground Water Basin Characterization) will inform this plan.  Groundwater Model – this will allow simulation and prediction of aquifer condition and improve the understanding of the movement of groundwater within the basin. The model would also be necessary to determine the potential benefit of various water supply enhancement projects and management strategies. Ultimately, this is the pivotal tool to allow the agencies to identify the most effective strategy for enhancing the conjunctive use of the basin and improving the water supply reliability for the region.  Recycled Water Supplemental Supply – this will allow the NCMA agencies to put their wastewater supplies to beneficial use. Through use of the groundwater model, alternative strategies for the implementation of recycled water (e.g. Item 11.a. - Page 16 CITY COUNCIL CONSIDERATION OF WATER SUPPLY STRATEGY AND AMENDMENTS TO CONSULTANT SERVICES AGREEMENTS FOR THE NORTHERN CITIES MANAGEMENT AREA WORK PROGRAM JUNE 10, 2014 PAGE 17 landscape irrigation, groundwater recharge, seawater intrusion barrier, and/or agricultural irrigation, etc.) can be analyzed to identify the most cost effective strategy for utilizing recycled water to develop a drought proof supplemental supply. Water Emergency Plan Staff is confident that the proposed measures present the most feasible and cost effective approach to meeting the City's long-term water needs based upon current projections and water sources. This includes the ability to accommodate normal drought cycles. In addition, efforts proposed by the NCMA will ensure the groundwater table is managed in the most responsible manner in order to best prevent damage to the viability of this water supply. However, any type of project to substantially protect the City's groundwater supply on a permanent basis will realistically take at least 10 years in a best case scenario, will be costly, and may ultimately be determined to be infeasible. In addition, the recommendations do not achieve a buffer in the future projected supply as was previously included in the former water supply strategy goals established. Therefore, it is important to recognize that these recommendations do not provide the diversification of water supply necessary to easily withstand an unanticipated extended drought. The City permanently implemented mandatory conservation measures that were formerly identified as a first and second stage of measures. This leaves only the option of implementing Critical Water Supply Condition measures, which are enacted when usage meets 100% of supply. As such, the City does not have the options necessary to implement escalating measures in response to an impending water crisis. In addition, the current declaration is based simply on water use as a percentage of supply. It does not address complex decisions that may be necessary involving the level of pumping that would be authorized if evidence of seawater intrusion were to occur. As a result, it is recommended that staff develop recommendations for an enhanced water emergency plan that can be implemented during a water emergency that may occur as a result of an extended drought. The purpose of the plan would be to provide measures that could be implemented on a phased basis as an emergency worsened, establish policy direction on how to respond to water supply management decisions during a severe extended drought, and to determine the practical steps that would be necessary to implement emergency measures when necessary. It is anticipated that the plan will be implemented through an ordinance that will include steps required when vulnerabilities in any City water supplies appear imminent. This plan would be developed in coordination with the NCMA Intertie Plan, Inter-agency Mutual Aid requirements and Water Shortage Contingency Plan. It will be important to develop this plan over the next few months because another drought year could begin to trigger water emergency conditions. Item 11.a. - Page 17 CITY COUNCIL CONSIDERATION OF WATER SUPPLY STRATEGY AND AMENDMENTS TO CONSULTANT SERVICES AGREEMENTS FOR THE NORTHERN CITIES MANAGEMENT AREA WORK PROGRAM JUNE 10, 2014 PAGE 18 City and Regional Coordination Consistent with the Urban Water Management Planning Act, the California Department of Water Resources (DWR) Drought Planning Guidance and the City’s Urban Water Management Plan, staff is recommending establishment of a Water Shortage Response Team (WSRT) for the purposes of water shortage contingency planning. Contingency planning before a shortage allows selection of appropriate responses consistent with the varying severity of shortages. The City’s WSRT is recommended to consist of the Community Development Director, Public Works Director, Administrative Services Director, Water Utilities Supervisor, and the Associate Planner/Water Conservation Coordinator. Regional coordination is central to protection of regional supplies, including the groundwater basin, surface water and ultimately to developing recycled water. It is recommended that a joint workshop with other jurisdictions and agricultural members be scheduled in the Fall. Ultimately, to meet State guidelines, a Regional Drought Task Force should also be established to include representatives from each agency. ALTERNATIVES: The following alternatives are provided for the Council’s consideration: 1. Approve staff’s recommendations; 2. Modify the proposed measures and/or targets and direct staff to proceed; 3. Develop more mandatory measures to reduce costs of incentives; 4. Pursue State Water purchase; 5. Pursue permanent purchase of water supply from OCSD or other jurisdictions; 6. Implement a drought surcharge per the State Water Code; or 7. Provide staff other direction. ADVANTAGES: Conservation efforts are the most cost effective option to address water needs and are within the City’s control to proceed. The proposed NCMA studies are designed to protect the groundwater supply and ensure the City will have access to its full allocation in the future of this water resource. Recommendations provide a feasible alternative to meet both demand and State requirements. Lastly, these initial steps can be fully funded without rate increases. DISADVANTAGES: The recommendations will result in a significant cost. In addition, a recycled water strategy will require future costs likely to trigger significant rate increases and will depend on cooperation of neighboring jurisdictions. The recommendations will likely not address demand during an extended drought period within the next ten year period. Lastly, by approving the agreement and amended agreement, the City will need to pay Item 11.a. - Page 18 CITY COUNCIL CONSIDERATION OF WATER SUPPLY STRATEGY AND AMENDMENTS TO CONSULTANT SERVICES AGREEMENTS FOR THE NORTHERN CITIES MANAGEMENT AREA WORK PROGRAM JUNE 10, 2014 PAGE 19 its share of the cost, which is approximately 31% according to the Arroyo Grande Groundwater Basin Management Agreement. ENVIRONMENTAL REVIEW: No environmental review is required for this item. PUBLIC NOTIFICATION AND COMMENTS: The Agenda was posted in front of City Hall on Thursday, June 5, 2014. The Agenda and staff report were posted on the City’s website on Friday, June 6, 2014. No public comments were received. Attachments: 1. NCMA 2013 Annual Report 2.

Similar to the ongoing 2013 Annual Report project on behalf of the NCMA, Fugro will team with GEl Consultants, Inc. (GEl) and Robert Almy to provide continuity with the same team as the past 4 years to meet the needs of the NCMA Technical Group. For the water quality laboratory analysis work, we will use either Capco Analytical Services or Pat-Chem Laboratories, both of which are CDPH ELAP-certified analytical testing laboratories. This proposal is similar in scope to the 2013 Annual Report work effort, and focuses on the scope of work needed to complete quarterly monitoring of the NCMA sentry wells and prepare the 2014 Annual Report. The proposed work effort will satisfy the primary requirements of the 2005 Stipulation through preparation of an Annual Report. Furthermore, information in the quarterly reports and Annual Report supports the Technical Group's on-going objective of effective water resources management. This year's anticipated fee is $140,000, which is a 12% increase over the 2013 Annual Report project fee. This fee is based on our experience working with the NCMA, the number of anticipated meetings throughout the year, and the effort required preparing the annual report. Thank you for the opportunity to continuing to work with you and the NCMA Technical Group. Copies Submitted: (PDF) Addressee Sincerely, ?:JNtr~ Paul Sorensen, C.Hg. Project Manager A member of the Fugro group of companies with offices throughout the world Item 11.a. - Page 22 Northern Cities Management Area Technical Group May 27, 2014 (Proposal No. 04.62149075) INTRODUCTION The Northern Cities Management Area (NCMA) Technical Group includes the Cities of Arroyo Grande, Grover Beach, and Pismo Beach and the Oceano Community Services District (OCSD). The minimum content of the Annual Report includes: • Summary of 2013 NCMA groundwater monitoring; • Changes in groundwater supplies; • Threats to the groundwater basin; • Tabulation of NCMA water use; • Imported water availability and use; • Developed water availability and use; and • Groundwater use. As before, we will use the above list as topical headings for preparation of the 2014 Annual Report. The following sections of this proposal present the scope of work to be performed, our approach and the tasks we will complete to produce the 2014 Annual Report for the NCMA Technical Group. The final sections of this proposal include the anticipated schedule and our cost estimate for completion of all tasks. PROJECT TEAM Fugro will serve as the prime contractor for the NCMA Annual Monitoring and Reporting Program with support by GEl and Rob Almy. The Fugro team will continue to serve the NCMA in largely the same manner as in the past year. Paul Sorensen, a hydrogeologist based in San Luis Obispo, will continue to act as Project Manager and main point of contact for the TG. Fugro will continue to gather water level and water quality data for the project on a quarterly basis and complete the data interpretation and report preparation in coordination with GEl and Rob Almy. For water quality testing, we will either to continue to rely on Capco Analytical Services, Inc. (Capco), or Pat-Chem Laboratories. Both firms are privately owned, full service, environmental and analytical testing laboratories certified by the State of California (CDPH ELAP certified). Both firms are located in the Ventura area, and Fugro has a long history of collaboration with both laboratories. 1 Item 11.a. - Page 23 Northern Cities Management Area Technical Group May 27, 2014 (Proposal No. 04.62149075) SCOPE OF WORK This scope of work is based on the following sources of information: a The requirements of the 2013 Request for Proposal, which formed the basis for our work for the past year, and; a Our experience preparing the Annual Reports and associated quarterly monitoring reports for 2010 through 2013 (four years); TASK 1.1 NCMA GROUNDWATER MONITORING AND REPORT SCHEDULE The current contract for technical services related to the 2013 Annual Report will terminate in September 2014. Assuming a Notice to Proceed {NTP) and authorization of the 2014 Annual Report project will be issued before October 2014, we will provide a detailed schedule of all tasks, anticipated meetings, and report preparation efforts within 14 days of the NTP. In order to complete the first round of monitoring by mid-October, which is the normal schedule for the 04 monitoring event, all agreements need to be in place by the first of October. TASK 1.2 MEETINGS, PROJECT MANAGEMENT, AND COMMUNICATION The NCMA Technical Group typically meets once per month, although the meeting frequency increased throughout much of late 2013 I early 2014. The Fugro project manager will participate in most of the regularly scheduled meetings. For budgeting purposes, we have assumed full participation in eight (8) of the regular monthly meetings, and teleconference participation in the other four ( 4) meetings. TASK 1.3 NCMA GROUNDWATER MONITORING AND WATER QUALITY SAMPLING Collection of groundwater level measurements and water quality information are core NCMA responsibilities. Four rounds of water level monitoring and quality testing will occur during: a The fourth quarter of 2014 (October 2014 ); a The first quarter of 2015 (January 2015); " The second quarter of 2015 (April 2015); and " The third quarter of 2015 (July 2015) During each sampling event, groundwater depth measurements will be collected in accordance with the American Society for Testing and Materials (ASTM) Standard D4750-87. Groundwater water quality samples are to be collected in accordance with the ASTM Standard D4448-1 using a variety of methods including, in the case of the Oceano CSD monitoring wells, low-flow methods. During each quarterly sampling event field personnel will: a Coordinate with and pick-up sample bottles and coolers from either Capco Analytical Services or Pat-Chem Laboratories, both of Ventura, California; " Collect a synoptic field measurements of depth to water (in accordance with ASTM Standard D4750-87) from all 16 wells including: o 32S/12E-24B01 through -24803 (North Beach Campground), 2 Item 11.a. - Page 24 Northern Cities Management Area Technical Group May 27, 2014 (Proposal No. 04.62149075) o 32S/13E-30F01 through -30F03 (Highway 1 ), o 32S/13E-30N01 through -30N03 (Pier Avenue), o 12N/23W-36L01 and -36L02 (Oceano Dunes), o Four Oceano CSD monitoring wells (3-inch diameter), and o 12N/35W-32C3 (County Monitoring Well #3; 11 Collect representative water samples from each of the 16 monitoring wells at six sites for general mineral analysis and in coordination with County of San Luis Obispo's quarterly sentry well field measurements. One of the Oceano CSD monitoring wells is damaged and is not sampled; a sample from Oceano CSD Well No. 8, which is completed to a similar depth, is collected in its place. Sampling of the 16 wells will be accomplished by the project hydrogeologist using a combination of ISCO-type peristaltic pumps, a Grundfos RediFio2 electric submersible pump as appropriate and as determined by the applicability of each well. Each well will be purged in accordance with ASTM D4448-1 until such time when field-measured water quality parameters stabilize and clear water is available. Samples will then be collected in sample containers with appropriate preservatives, placed in iced coolers immediately following sample collection, and maintained at appropriate temperature for transportation to the laboratory. Chain-of-custody documentation will be completed for all samples. Data collected from the field and laboratory reports will be reviewed by the project hydrogeologist and project engineer as part of the project QA/QC procedures. Data will be reviewed for compliance with ASTM standards. Any data not meeting standards for accuracy or reliability will be flagged and addressed, with new data collected as appropriate. All data satisfying the QA/QC procedures will be entered in the NCMA database, evaluated by consultant team members (as discussed under Task 1.4) and compiled into a draft quarterly report for review. Sensors measuring pressure and electrical conductivity are installed in five wells including: II Well 32S/12E-24B 1; 13 32S/12E-24B3; m 32S/13E-30F3; D 32S/13E-30N2; and D 12N/35W-32C3. Data from the transducers will be downloaded during quarterly monitoring, calibrated as needed, compensated for atmospheric pressure variation, then referenced to the project elevation model. This data will be subjected to QA/QC procedures then entered in the NCMA database. This data will be interpreted and influences such as regional water level changes, tidal fluctuations, storm surges, or system pumping discussed. We will continue to sample Oceano CSD Well No. 8 instead of the Oceano CSD "Silver" Monitoring Well due to apparent damage to the "Silver" Well. 3 Item 11.a. - Page 25 Northern Cities Management Area Technical Group May 27, 2014 (Proposal No. 04.62149075) TASK 1.4 NCMA GROUNDWATER DATA ANALYSIS We will compile and review all data from quarterly ground-water measurements and laboratory analysis, as well as any applicable data collected by the County of San Luis Obispo. The data will be evaluated and indications of potential hazards (such as well interference, water quality degradation, and seawater intrusion) will be identified. The data and analysis will be included in the quarterly report sent to the NCMA Technical Group within five weeks of the sampling event. Water level data will be used to generate hydrographs and contour maps for the annual report. Water level contour maps during spring and fall conditions will be generated. We will calculate and provide a diagram of the "deep well index." Representative plots of historical water quality time-series data for key constituents will be generated at wells with adequate control to show changes over time in mineral concentrations for these key constituents. Special attention will be paid to coastal wells. TASK 1.5 HYDROLOGIC DATA COMPILATION Several sets of hydrologic data are essential for preparation of the Annual Report. Some (such as weather data) will be obtained directly from outside sources. We propose to use the approach currently employed in our most recent data collection and analysis efforts. During the project, if the we recognize other potential improvements to data sources or methodology that would result in better or more efficient analysis, we will consult with the TG and either incorporate those improvements directly in our work or suggest the changes for subsequent annual reports, as appropriate. TASK 1.6 NCMA WATER DEMAND AND AVAILABILITY ANALYSIS We will prepare a detailed analysis of water demand and availability within the NCMA. Data collection and analysis shall be sufficient to determine land and water uses in the NCMA, sources of supply to meet those uses, groundwater availability, the amount and disposition of developed water supplies, and the amount and disposition of any other water supply sources within the NCMA. The approach and tabulation of results will be included in the annual report. For preparation of the 2014 Annual Report, we will generally follow the established methods used in the 2013 Annual Report and those methods developed for the Monitoring Program for the NCMA, July 2008. As performed as part of the 2012 and 2013 Annual Reports, we will continue to use a modified approach to calculate applied irrigation for agricultural demand, the results of which were very close (within 2 percent) to the previous method. Each component of water use will be evaluated. Urban demands are based on actual production. Rural demand is estimated and we will likely continue to rely on previous estimates so long as no significant land use changes occur. Applied irrigation demand is an indirect estimate using crop-type specific irrigation requirements by acre and land use data. The project engineer will calculate the applied irrigation demand based on table values for irrigation scheduling and net water use by crop and irrigation methods provided by the ITRC (www.itrc.org). 4 Item 11.a. - Page 26 Northern Cities Management Area Technical Group May 27, 2014 (Proposal No. 04.62149075) The NCMA has three major sources of water supply: Lopez Reservoir, California State Water Project (SWP), and groundwater. All four municipalities in the NCMA receive water from Lopez Reservoir. Data on the volume of Lopez deliveries will be compiled for each municipality. The City of Pismo Beach and Oceano Community Services District receive water from the SWP. Data on the volume of water delivered to these municipalities will be compiled in the NCMA database. Groundwater pumping data are recorded by location and volume by the NCMA. Non- urban domestic and agricultural groundwater pumping is estimated. These data will be compiled in the NCMA database. TASK 1.7 2014 NCMA ANNUAL REPORT PREPARATION The Fugro team will prepare an Administrative Draft Annual Report for the NCMA Technical Advisory Group. The report will be based on data collected and analysis performed as described above, on other data that may become available, and on ongoing discussions with the NCMA TG. Minimum contents of the report will include: a Summary of the 2014 NCMA groundwater monitoring; a Changes in groundwater supplies; a Threats to the groundwater basin; a Tabulation of NCMA water use; a Imported water availability and use; and a Developed water availability and use. Electronic copies of the Administrative Draft Annual Report will be provided to the NCMA and legal counsel a minimum of 8 weeks prior to the report deadline of April 30. Assuming approximately 2 weeks of review time by the TG and 2 weeks to revise the Administrative Draft and prepare a Draft Report, the Draft Report will be re-submitted to the NCMA via e-mail approximately 4 weeks prior to the deadline for the final report. All comments on the Draft Report will be compiled and incorporated into the Final Report. Electronic copies of the Final 2014 Annual Report will be provided in PDF format. 5 Item 11.a. - Page 27 Northern Cities Management Area Technical Group May 27, 2014 (Proposal No. 04.62149075) SCHEDULE AND FEE Meeting the NCMA schedule is of the utmost importance. We will adhere strictly to the schedule outlined below in order to meet the required Report submittal by April 30, 2015, as well as the quarterly sampling events and reports.

The Annual Report provides an assessment of hydrologic conditions for the NCMA based on data collected during the calendar year of record. As specified in the Judgment, the Northern Cities agencies, consisting of the City of Arroyo Grande, City of Grover Beach, City of Pismo Beach, and Oceano Community Services District, are to conduct groundwater monitoring in the NCMA, and collect and analyze data pertinent to water supply and demand, including:  Land and water uses in the basin;  Sources of supply to meet those uses;  Groundwater conditions (including water levels and water quality);  Amount and disposition of developed water supplies; and  Amount and disposition of other sources of water supply in the NCMA. Results of the data compilation and analysis for calendar year 2013 are documented and discussed in this Annual Report. 1.1 FINDINGS  Rainfall in the NCMA for calendar year 2013 was 4.32 inches, equal to 27 percent of the long-term average annual rainfall for the area. Below average rainfall occurred for eight of the twelve months. Most rainfall typically falls from November through April, however the year was marked by substantially lower than average rainfall (21 percent of normal) in the “wet” months of January, February, March, April, November, and December.  Spring (April 2013) groundwater level elevations underlying the NCMA shows groundwater elevations highest in the eastern portion of the NCMA and approximately 5 feet above sea level along the shore line. A relatively shallow westward-facing pumping trough developed in the Spring 2013 in the northern part of the area, apparently in response to municipal pumping in the Arroyo Grande and Grover Beach area. A comparison with Spring 2012 contours shows that Spring 2013 water levels were generally 10 to 15 feet lower throughout the NCMA from one year ago.  Fall groundwater elevations in October 2013 were also highest in the eastern portion of the NCMA, and approximately 2 to 5 feet above sea level along the shoreline. Groundwater elevations were generally above mean sea level (msl) in the Fall throughout the NCMA, with the exception of a few measurements in agricultural wells in the east-central part of the area where water level elevations were measured as deep as 6.7 feet below msl. These lower water level elevations maintain the previously recognized depression in the water table in the so-called “pumping trough,” located Item 11.a. - Page 38 NCMA 2013 Annual Monitoring Report April 28, 2014 (Project No. 04.62130129) 2013 NCMA Annual Report Final.Doc - ES2 - south of the municipal well fields and in the vicinity of, and south of, lower Arroyo Grande Creek. Water elevations in this area are generally 5 to 10 feet lower than levels measured in Fall 2012.  Total water use in the NCMA in 2013, including urban use by the Northern Cities agencies as well as applied irrigation and private pumping by rural water users, was 10,722 acre feet (AF). Of this amount, groundwater pumping accounted for approximately 4,206.7 AF. The breakdown is shown on the following table. Urban Area Lopez Lake State Water Project Groundwater Transfers Other Supplies Total Arroyo Grande 2,722.3 0.0 268.4 0.0 120.2 3,110.9 Grover Beach 802.7 0.0 988.8 0.0 0.0 1,791.5 Pismo Beach 1,457.4 618.0 73.0 0.0 0.0 2,148.4 Oceano CSD 44.9 750.0 92.8 0.0 0.0 887.7 Urban Water Use Total 5,027.3 1,368.0 1,423.0 0.0 120.2 7,938.5 Applied Irrigation 0.0 0.0 2,742.0 0.0 0.0 2,742.0 Rural Water Users 0.0 0.0 41.7 0.0 0.0 41.7 Total 5,027.3 1,368.0 4,206.7 0.0 120.2 10,722.2  In April 2013 municipal groundwater pumpage was increased to replace temporarily unavailable supplies from Lake Lopez. As a result, the groundwater level in Sentry Well 30F03 (Highway 1 well) declined by as much as 14 feet in 7 days and was below sea level for a total of 6 days. The decline in water level due to increased pumpage required almost two weeks to recover to the initial water levels observed prior to the increased pumping. Similar water level declines, albeit of less magnitude, were also observed in deep wells 24B03 (North Beach Campground) and 30N02 (Pier Avenue).  Averaging the groundwater elevations from the three deep sentry wells provides a single, representative index for tracking the status and apparent health of the basin. Previous studies suggest that the deep well index is 7.5 feet NAVD88. As described in previous Annual Reports, the measured index values of the three deep wells remained below 7.5 feet between October 2007 and August 2009, during which high concentrations of chloride and sodium occurred in two sentry wells in late 2009. This relationship implies a lag in time between lowered water levels in the deep sentry wells and significant increases in sodium and chloride. This is potentially significant because the measured index level was as much as 6 feet below the index value of 7.5 in April 2013 and remained at or below the index from early June 2013 until mid-December 2013. Continued average values below the index create a potential environment for increased risk of sea water intrusion.  The index value ended the year above the 7.5-foot index level. However, February through April is the time of year that historically has the highest index level value (at least since January 2010). The index value at the end of 2013 is 2 to 4 feet lower than Item 11.a. - Page 39 NCMA 2013 Annual Monitoring Report April 28, 2014 (Project No. 04.62130129) 2013 NCMA Annual Report Final.Doc - ES3 - the end of year levels of 2010 through 2012. If the wells experience a 1-foot rise through February to April followed by a 5-foot decline in water level elevations until October 2014 (as is typical in past years), then the index value may potentially be as low as 4 feet in October 2014. Considering the effects of any increased pumpage related to anticipated cutbacks in surface water deliveries, the index level may approach the level seen in 2008-2009, just prior to observing the elevated chloride concentrations in the Pier Avenue well.  Minor variations and changes in water quality were observed in the sentry wells throughout the year; however there are no indications of sea water intrusion in the deeper levels of the groundwater production zone.  The various water quality indicators observed in 2013 suggest that the local interface/mixing zone between seawater and fresh groundwater remains seaward of the sentry wells (shoreline). The location of the seawater interface is not known due to the heterogeneity of the aquifer. The only indication of the location of the interface would be when one or more monitored wells show an increase in total dissolved solids, chlorides, sodium, or other constituent along with a geochemical signature resembling seawater. These changes may be brought on by reduced recharge (e.g. drought conditions) or if pumping exceeds available groundwater supply, or both.  Numerous management objectives are described in the Annual Report, including strategies to meet the objectives. Due to potential constraints on supply, all NCMA agencies, both individually and jointly, are engaged in water resource management projects, programs, and planning efforts that address water supply and demand issues, particularly efforts to assure a long-term sustainable supply. Constraints on supply include drought cycles, limitations on surface water allocations and risk of seawater intrusion of the aquifer system.  A key water supply planning and management activity started in late 2013 by the NCMA is the initiation of joint Strategic Planning efforts for the purpose of providing the NCMA Technical Group with a framework for identifying common water resource planning goals and objectives, and to establish a 10-year work plan for implementation of those efforts. Several key objectives have been identified, including water supply reliability, increased outreach, and basin management. These efforts will continue throughout 2014.  The deepening pumping depression within the NMMA and expansion of the groundwater depression to the west and north, towards the NCMA, appears to have eliminated the historical groundwater divide between the NCMA and NMMA. With the loss of this divide there has been a reversal of groundwater gradients and the development of a landward gradient in the southern portion of the NCMA. This landward gradient eliminates the historic recharge volume of subsurface inflow into the NCMA (thereby reducing the yield of the aquifer), and creates conditions favorable for seawater intrusion in the NCMA and NMMA. To mitigate the risk of seawater intrusion and restore the subsurface inflow into the aquifer, immediate conservation measures must be made to reduce demand in the NMMA. Additionally, the County of San Luis Obispo, which possesses land use authority, must restrict any future development that increases water demand in the NMMA. Item 11.a. - Page 40 NCMA 2013 Annual Monitoring Report April 28, 2014 (Project No. 04.62130129) 2013 NCMA Annual Report Final.Doc - 1 - 2.0 INTRODUCTION 2.1 INTRODUCTION This report summarizes hydrologic conditions during the calendar year 2013 in the Northern Cities Management Area (NCMA) of the Santa Maria Groundwater Basin (SMGB) in San Luis Obispo County, California. This report was prepared on behalf of four public agencies collectively referred to as Northern Cities, which includes the City of Arroyo Grande (Arroyo Grande), City of Grover Beach (Grover Beach), City of Pismo Beach (Pismo Beach) and the Oceano Community Services District (Oceano CSD). These agencies, along with local land owners, the County of San Luis Obispo (County), and the San Luis Obispo County Flood Control & Water Conservation District (SLOFCWCD) have managed local surface water and groundwater resources in the area since the late 1970s to preserve the long-term integrity of water supplies. The collaborative approach was formalized in the 2002 Management Agreement between the Northern Cities, Northern Landowners, and Other Parties, and incorporated in the 2005 Settlement Stipulation for the Santa Maria Groundwater Basin Adjudication (Stipulation). On June 30, 2005 the Stipulation was agreed upon by numerous parties, including the Northern Cities. The “Settlement Agreement” attached to the Stipulation included the Management Agreement of 2002. The approach was then adopted by the Superior Court of California, County of Santa Clara, in its Judgment After Trial, entered January 25, 2008 (Judgment). Although appeals to that decision were filed, a subsequent decision by the Sixth Appellate District (filed November 21, 2012) has upheld the Court’s Judgment. Most recently, the Supreme Court of California denied a petition to review the decision on February 13, 2013. The Judgment orders the stipulating parties to comply with all terms of the Stipulation. The 2002 Settlement Agreement is generally affirmed as part of the Judgment and its terms incorporated into the Stipulation. However provisions of the Stipulation supersede the 2002 Settlement Agreement in the areas of continuing jurisdiction, groundwater monitoring and reporting. As specified in the Judgment and as outlined in the Monitoring Program for the Northern Cities Management Area (Monitoring Program, Todd 2008), the Northern Cities agencies are to conduct groundwater monitoring of wells in the NCMA. In accordance with requirements of the Judgment, the agencies comprising the NCMA group collect and analyze data pertinent to water supply and demand, including:  Land and water uses in the basin;  Sources of supply to meet those uses;  Groundwater conditions (including water levels and water quality);  Amount and disposition of developed water supplies; and,  Amount and disposition of other sources of water supply in the NCMA. The Monitoring Program requires that the NCMA gather and compile pertinent information on a calendar year basis; this is accomplished through data collected by Northern Cities agencies (including necessary field work), requests to other public agencies, and from online sources. Periodic reports such as Urban Water Management Plans (UWMP) prepared by the Cities of Arroyo Grande, Grover Beach and Pismo Beach provide information on demand, supply, and Item 11.a. - Page 41 NCMA 2013 Annual Monitoring Report April 28, 2014 (Project No. 04.62130129) 2013 NCMA Annual Report Final.Doc - 2 - water supply facilities. Annual data are added to the comprehensive Northern Cities Management Area Database (NCMA DB) and analyzed. Results of the data compilation and analysis for calendar year 2013 are documented and discussed in this Annual Report. As shown on Figure 1, the Northern Cities Management Area (NCMA) represents the northernmost portion of the Santa Maria Groundwater Basin, as defined in the adjudication and by California Department of Water Resources (DWR 1958) as the Santa Maria River Valley groundwater basin (Basin 3-12). Adjoining the NCMA to the southeast is the Nipomo Mesa Management Area (NMMA); the Santa Maria Valley Management Area (SMVMA) encompasses the remainder of the groundwater basin. Figure 2 shows the locations of the four Northern Cities agencies within the NCMA. 2.2 BACKGROUND 2.2.1 Description of the Northern Cities Management Area Technical Group The NCMA Technical Group (TG) is composed of representatives of Arroyo Grande, Grover Beach, Pismo Beach, and Oceano CSD (Table 1). Table 1.

Fine, PE Director of Public Works/City Engineer Oceano Community Services District Tony Marracino Utility Systems Supervisor The TG contracts with a consulting firm to serve as staff extension to assist the TG in all functions of the roles and responsibilities of the TG for purposes of managing the water supply resources. The TG also contracts with a consulting firm to conduct the quarterly groundwater monitoring and sampling tasks, evaluate water demand and available supply, identify threats to water supply, and assist the group in preparation of the Annual Report. Item 11.a. - Page 42 NCMA 2013 Annual Monitoring Report April 28, 2014 (Project No. 04.62130129) 2013 NCMA Annual Report Final.Doc - 3 - 2.2.2 Coordination with Management Areas Since 1983, management of the NCMA has been based on cooperative efforts of the four Northern Cities agencies with ongoing collaboration with San Luis Obispo County, the SLOFCWCD, and other local and state agencies. Specifically the NCMA agencies have limited their pumping and, in cooperation with SLOFCWCD, invested in surface water supplies so as to not exceed the safe yield of the NCMA portion of the Santa Maria Valley groundwater basin (SMGB). Other organizations participate as appropriate to the issues of the time. In addition to the efforts discussed in the report, cooperative management occurs through many means including communication of the Northern Cities in their respective public meetings and participation in the Water Resources Advisory Council (the County-wide advisory panel on water issues). The NCMA agencies participated in preparation and adoption of the 2007 San Luis Obispo County Integrated Regional Water Management Plan (IRWMP), and are participating in the ongoing IRWMP update efforts. The IRWMP promotes integrated regional water management to ensure sustainable water uses, reliable water supplies, better water quality, environmental stewardship, efficient urban development, protection of agriculture, and a strong economy. Since the 2008 Judgment, the NCMA has taken the lead in cooperative management of its management area. The NCMA has also been a proactive participant in the Santa Maria Groundwater Basin Management Area technical subcommittee, which formed in 2010. These efforts continued throughout 2013. The NCMA Technical Group met monthly (at a minimum) throughout 2013. The group also met four times with the NMMA and SMVMA groups. The coordination among the management areas is leading to joint projects such as enhanced monitoring of groundwater levels and improved sharing of data. A key water supply planning and management activity started in late 2013 by the NCMA is the initiation of joint Strategic Planning efforts for the purpose of providing the NCMA Technical Group with a framework for identifying common water resource planning goals and objectives, and to establish a 10-year work plan for implementation of those efforts. Several key objectives have been identified, including water supply reliability, increased outreach, and basin management. These efforts will continue throughout 2014. Item 11.a. - Page 43 NCMA 2013 Annual Monitoring Report April 28, 2014 (Project No. 04.62130129) 2013 NCMA Annual Report Final.Doc - 4 - 3.0 BASIN DESCRIPTION 3.1 SETTING The Santa Maria Groundwater Basin, as defined in the adjudication and as defined by the Department of Water Resources (DWR 1958) as the Santa Maria River Valley groundwater basin (Basin 3-12), generally has three hydrologic elements. As shown in Figure 1 (following text), the Northern Cities Management Area (NCMA) represents the northernmost portion of the Santa Maria Groundwater Basin. Adjoining the NCMA to the southeast is the NMMA, while the Santa Maria Valley Management Area encompasses the remainder of the groundwater basin. Groundwater pumped from the NCMA is derived from the Paso Robles Formation comprising heterogeneous alluvial materials that extend westward at depth beneath the ocean. The northern and eastern portions of the basin are bounded by bedrock and faults that potentially reduce groundwater recharge by underflow. The southern boundary of the NCMA is coincident with the NMMA portion of the Santa Maria Groundwater Basin and historically has been considered a groundwater divide and source of recharge (DWR 2002). The groundwater resource developed in the NCMA has several sources of recharge: precipitation, seepage from stream flow, and underflow from adjacent areas. In addition, some return flow occurs from imported surface sources: Lopez Reservoir and the State Water Project. Groundwater gradients show that discharge occurs from the groundwater basin in the NCMA area to the ocean. As discussed in Section 4.1, this discharge and positive westward gradient controls the risk of seawater from entering the production zones of the basin aquifer. 3.2 CLIMATE Each year climatological and hydrologic (stream flow) data for the NCMA are added to the NCMA database. Annual precipitation from 1950 to 2013 is presented on Figure 3. Monthly rainfall and evapotranspiration (ET) for 2013 as well as average monthly historical rainfall and ET are presented on Figure 4. 3.2.1 Precipitation Historical rainfall data have been compiled on a monthly basis for the following four stations:  National Oceanic and Atmospheric Administration (NOAA) Pismo Beach Fire Station (Coop ID: 46943) for 1949 to Present;  DWR California Irrigation Management Information System (CIMIS) Nipomo Station (No. 202) for 2006 to Present;  Desert Research Institute (DRI): Western Regional Climate Center Pismo Station for 1950 to Present; and,  San Luis Obispo County-operated rain gage in Oceano for 2005 to 2009. Based on the acquired data for the four rainfall stations listed above, the average rainfall for calendar year 2013 was 4.32 inches, equal to 27 percent of the long-term average annual rainfall for the NCMA. Item 11.a. - Page 44 NCMA 2013 Annual Monitoring Report April 28, 2014 (Project No. 04.62130129) 2013 NCMA Annual Report Final.Doc - 5 - Below average rainfall occurred for eight of the twelve months (67 percent of year; Figure 4). Most rainfall typically occurs from November through April. The year 2013 was marked by substantially lower than average rainfall (21 percent of normal) in the “wet” months of January, February, March, April, November, and December. Average precipitation data is presented on Figure 3 for the period of 1950 through 2013 on a calendar year basis. Annual average rainfall for the NCMA for the period is approximately 16.1 inches. Figure 3 illustrates annual rainfall and exhibits several multi-year drought cycles (e.g., 7 years, 1984-1990) followed by cycles of above average rainfall (e.g., 8 years, 1991-1998). With the exception of 2010, the period 2006 through 2013 (8 years) has experienced below average annual rainfall suggesting a “dry” hydrologic period. The average rainfall 2006 through 2013 (including 2010) is 10.3 inches, 64 percent of the long-term average. 3.2.2 Evapotranspiration The California Irrigation Management Information System (CIMIS) maintains weather stations in locations throughout the state in order to provide real time wind speed, humidity and ET data. Two CIMIS stations are located near the NCMA; Nipomo and San Luis Obispo. The Nipomo and San Luis Obispo stations have gathered data since 2006 and 1986, respectively. Monthly ET data for the Nipomo station are presented on Figure 4 for 2013 and average (7-years) conditions. ET rate affects recharge potential of rainfall and the amount of outdoor water use (irrigation). In all months, ET exceeded rainfall, indicating the recharge to groundwater from direct precipitation in 2013 was likely nonexistent.

Each source of supply has a defined delivery volume which varies from year to year based on a number of factors. Both supply and demand are discussed below; demand is discussed in more detail in Section 4.2. 4.1.1.1 Lopez Lake Lopez Lake and Water Treatment Plant is operated by SLOFCWCD Zone 3, provides water to all four agencies in the NCMA, and releases water to Arroyo Grande Creek for habitat conservation and agricultural purposes. The safe yield of Lopez Lake is 8,730 acre feet per year (AFY), which reflects the amount of sustainable water supply during a drought of defined severity. Of this yield, 4,530 AFY has been apportioned by agreements to contractors including each of the Northern Cities plus County Service Area (CSA) 12 (in the Avila Beach area). Zone 3 allocations are summarized in Table 2. Of the 8,730 AFY safe yield, the remaining 4,200 AFY is used for downstream releases to maintain flows in Arroyo Grande Creek and provide groundwater recharge. Table 2.

Surplus water was available in 2013, resulting in the delivery of 2,715 AF of surplus water from Lopez Item 11.a. - Page 46 NCMA 2013 Annual Monitoring Report April 28, 2014 (Project No. 04.62130129) 2013 NCMA Annual Report Final.Doc - 7 - Lake to the NCMA agencies. Total discharge from Lopez Lake in 2013 was 9,428.9 acre feet (AF), of which 5027.3 AF was delivered to NCMA contractors, 123.3 AF delivered to CSA 12, and 4,278.3 AF was released downstream to maintain flow in Arroyo Grande Creek (individual deliveries are shown in Table 3). Table 3. 2013 Lopez Lake Deliveries (AF) Agency 2013 Allocation Usage (AF) 2013 Surplus Usage (AF) 2013 Total Lopez Lake Water Delivery, (AF) City of Arroyo Grande 1,188.1 1,534.2 2,722.3 City of Grover Beach 266.7 536.0 802.7 City of Pismo Beach 857.1 600.3 1,457.4 Oceano CSD 0 44.9 44.9 Total NCMA 2013 Usage 2,311.9 2,715.4 5,027.3 CSA 12 (not in NCMA) 0 123.3 123.3 Downstream Releases 4,278.3 -- 4,278.3 Total 2013 Lopez Lake Deliveries 9,428.9 During April maintenance work was performed on the Lopez Lake Pipeline. During that period no deliveries were made. As discussed below, groundwater was used to make up the lost supplies. 4.1.1.2 State Water Project Pismo Beach and Oceano CSD have contracts with SLOFCWCD to receive water from the State Water Project (SWP). The SLOFCWCD serves as the SWP contractor, providing the imported water to local retailers through the Coastal Branch pipeline. Pismo Beach and Oceano CSD have contractual water delivery allocations (commonly referred to as “Table A” water) of 1,240 AFY and 750 AFY, respectively (see Table 4, page 10). In addition to its Table A allocation, Pismo Beach holds 1,240 AFY of additional allocation with SLOFCWCD. The additional allocation held by Pismo Beach (usually referred to as a “drought buffer”) is available to augment requests when the state-wide SWP allocations are insufficient to meet local needs. This “drought buffer” is an additional amount that the SLOFCWCD holds in excess of the contracted amount that can be delivered when there is a reduced delivery; however the total of water delivered between the base contractual allocation and drought buffer cannot exceed 1,240 AF in any given year. In addition, the drought buffer allocation is also reduced by the percent delivery set by DWR and so may not allow Pismo Beach full deliveries of 1,240 AFY in years when deliveries are less than 50%. On November 29, 2012, in response to state-wide drought in SWP source areas, the initial allocation to SWP contractors for 2013 was set at 30 percent of Table A contractual allocation amounts. On December 21, 2012 the allocation amounts were increased to 40 percent, then subsequently decreased to 35 percent on March 22, 2013 based on the amount of water in SWP Item 11.a. - Page 47 NCMA 2013 Annual Monitoring Report April 28, 2014 (Project No. 04.62130129) 2013 NCMA Annual Report Final.Doc - 8 - facilities and expected operational constraints in the Delta. As a result Pismo Beach and Oceano CSD modified their planning to maximize their SWP deliveries. Oceano CSD accepted 35% of their 750 AF allocation and purchased additional water from the SLOCFCWCD and a new State program allowing purchase of carryover water held in San Luis Reservoir. In 2013, Pismo Beach took actual delivery of 618 AF and Oceano CSD took delivery of 750 AF, for a total delivery of 1,368 AF of SWP water to NCMA (Table 9, page 25). 4.1.1.3 Groundwater Each of the NCMA agencies have established groundwater supplies using wells which draw from developed aquifers in the northern portion of the NCMA. Groundwater also satisfies applied irrigation and rural uses in the NCMA. Groundwater use in the NCMA is governed by the Judgment and the 2002 Settlement Agreement which establishes that groundwater will continue to be allotted and independently managed by the “Northern Parties” (Northern Cities, NCMA overlying owners, and the SLOFCWCD). A safe yield value of 9,500 AFY for the NCMA groundwater basin was cited in the 2002 Groundwater Management Agreement among the Northern Cities with allotments for applied irrigation (5,300 AFY), subsurface outflow to the ocean (200 AFY), and urban use (4,000 AFY). The Management Agreement’s safe yield allotment for urban use was subdivided as follows and as shown in Table 4:  City of Arroyo Grande: 1,202 AFY  City of Grover Beach: 1,198 AFY  City of Pismo Beach: 700 AFY  Oceano Community Services District: 900 AFY According to Todd (2007), the Groundwater Management Agreement’s subdivision for applied irrigation is higher than the actual applied irrigation groundwater use and the amount designated for subsurface outflow is unreasonably low. Since anticipated agriculture expansion is not significant and long term increased use is unlikely, the current balance of water use between agriculture and municipal uses has been sustainable for the last 40 years. Maintenance of subsurface outflow along the coast is essential to preventing seawater intrusion. While the minimum subsurface outflow needed to prevent seawater intrusion is unknown, a regional outflow on the order of 3,000 AFY has been estimated as a reasonable approximation (Todd, 2007). The 2002 Management Agreement provides that allotments of the various urban parties can be increased when land within the corporate boundaries is converted from agricultural uses to urban uses, referred to as an agricultural conversion credit. Agricultural credits for the cities of Arroyo Grande and Grover Beach did not change from 2011. The agricultural credit for 2013 for Arroyo Grande and Grover Beach remain unchanged from 2012 and are 121 AFY and 209 AFY, respectively, for a total of 330 AFY (Table 4). 4.1.1.4 Developed Water As defined in the Stipulation, “developed water” is “Groundwater derived from human intervention” and includes “Lopez Lake Water, Return Flow, and recharge resulting from storm Item 11.a. - Page 48 NCMA 2013 Annual Monitoring Report April 28, 2014 (Project No. 04.62130129) 2013 NCMA Annual Report Final.Doc - 9 - water percolation ponds.” Return flow results from deep percolation of water used in irrigation that is in excess of plant needs and from outdoor uses of Lopez Lake and SWP deliveries. These return flows have not been recently estimated, but would be considered part of the groundwater basin yield. In 2008, the cities of Arroyo Grande, Grover Beach, and Pismo Beach prepared storm water management plans. The cities currently are working with the Central Coast Regional Water Quality Control Board to address local storm water quality issues. In order to control storm water runoff, each City anticipates construction of retention or detention ponds associated with new development that may provide groundwater recharge. During 2013, no new ponds were installed in the NCMA and no new data were available, so previous estimates of recharge were used in this report. Estimated recharge values should be updated and refined as new recharge facilities are installed and as additional information on flow rates, pond size, infiltration rates, and tributary watershed area becomes available. Construction of recharge basins or other means to increase groundwater recharge could substantially augment the yield of the groundwater basin and thus warrant provision of recharge credits to one or more of the Northern Cities. Pursuant to the Settlement Agreement, recharge credits would be based on a mutually-accepted methodology to evaluate the amount of recharge which would involve quantification of such factors as Lopez Lake and State Water recharge, storm water runoff amounts, determination of effective recharge under various conditions, and methods to document actual recharge to developed aquifers. 4.1.1.5 Water Use by Supply Source Table 4 summarizes the water supplies currently available to the Northern Cities, including Lopez Lake allocation, SWP allocations, groundwater allotments, and agricultural credits. In addition to direct available supplies, the Lopez water year 2013-14 was the final year of a 5-year agreement between Arroyo Grande and Oceano CSD for the temporary purchase of groundwater or Lopez Lake supplies. No transfers were completed in Calendar Year 2013. The final transfer was completed in January 2014, therefore is not reflected in this report. The category of “Other Supplies” includes groundwater pumped from outside the NCMA boundaries. A graphical depiction of the water use sorted by supply source for each NCMA agency since 1999 is presented as Figure 5. The graphs depict changes in water supply availability and use over time, including the increased use of SWP water (to a maximum in 2001). The figure also indicates the reduced and less variable Lopez Lake water use due to the unavailability of Lopez Lake surplus flows from 2002 to 2008. Although no recycled water was available in 2013, plans have been developed to construct recycled water facilities (see Section 6.2.5). Item 11.a. - Page 49 NCMA 2013 Annual Monitoring Report April 28, 2014 (Project No. 04.62130129) 2013 NCMA Annual Report Final.Doc - 10 - Table 4.

As shown, the full amount of Lopez Lake supply (4,289 AFY) is currently used (augmented by surplus water as available). In 2001 through 2003, SWP supplies (1,850 AFY) were used to the maximum extent. From 2004 to 2008, SWP use decreased to just over 1,100 AFY, mostly reflecting a partial shift by Pismo Beach from SWP to groundwater supply. This changed in 2009 and 2010 when Pismo Beach increased SWP use and significantly decreased groundwater use to provide a more economical water supply and to ease the burden on the groundwater basin during the drought (see Figure 5). In 2013 Pismo Beach took delivery of 618 AF of SWP water (50% allocation) and pumped 73.01 AF from the groundwater basin. In 2013 Oceano CSD took delivery of 750 AF of SWP water (100% allocation) and pumped 92.84 AF from the groundwater basin. Total NCMA groundwater use is shown in Table 5 (following page) and Figure 6. Estimated applied irrigation and rural uses are added to the urban uses detailed in Table 5 and Figures 5 and 6. From 1999 through 2013, total estimated groundwater use averaged approximately 5,087 AFY and exceeded 6,000 AFY in 2007 and 2008. With an estimated safe yield of 9,500 AFY, the remaining groundwater represents storage and outflow to the ocean, an unknown but major portion of which is needed to repel seawater intrusion. Groundwater pumpage reached a peak in 2007, and then declined in 2008, 2009, and 2010. Since 2010, although there has been a slight but steady increase in pumpage every year, overall groundwater use has remained significantly lower than historic annual pumpage rates. In 2013, urban groundwater use increased 25%, from 1,138 in 2012 to 1,423 AF. Although urban groundwater pumpage has been slowly increasing the past few years, it still remains significantly below the 4,000 AFY allotment.

Analysis of this data is summarized below in accordance with the July 2008 Northern Cities Monitoring Program. 4.1.2.1 Groundwater Monitoring Network Approximately 145 wells within the NCMA were monitored by the County at some time during the past few decades. The County currently monitors 38 wells on a semi-annual basis (April and October), including five “sentry well” clusters (piezometers) located along the coast and a newly constructed monitoring well (County Well #3) along the boundary between the NCMA and NMMA (Figure 7). The County monitors more than 70 additional wells in southern San Luis Obispo County. Following the findings of the 2008 Annual Report, the Northern Cities initiated a quarterly sentry well monitoring program to supplement the County’s semi-annual schedule. The quarterly monitoring well measurements include County Well #3. To monitor overall changes in groundwater conditions, representative wells within the NCMA were selected for preparation of hydrographs and evaluation of water level changes. Wells were selected based on the following criteria:  The wells must be part of the County’s current monitoring program;  Detailed location information must be available;  The wells should have a wide geographic distribution; and,  The historic record of water level data must be long and relatively complete. Many of the wells that have been used in the program are production wells that were not designed for monitoring purposes and may be screened in various producing zones. Moreover, Item 11.a. - Page 51 NCMA 2013 Annual Monitoring Report April 28, 2014 (Project No. 04.62130129) 2013 NCMA Annual Report Final.Doc - 12 - many of the wells are active production wells or located near active wells and thus are subject to localized pumping effects that result in measurements that are lower than the “static” or more broadly representative water level. These effects are not always apparent at the time of measurement. As a result, the data cannot easily be identified as representing static groundwater levels in specific zones (e.g., unconfined or deep confined). Hence, the data should be considered as a whole in developing a general representation of groundwater conditions. The “sentry wells” are a critical element of the groundwater monitoring network and provide an early warning system to identify and quantify potential seawater intrusion episodes in the basin (Figure 7). Each sentry well consists of a cluster of multiple wells allowing for the measurement of groundwater elevation and quality from discrete depths. Also shown on Figure 7 is the Oceano CSD Observation well cluster, a dedicated monitoring well cluster located just seaward of Oceano CSD production wells 7 and 8. Figure 8 shows the depth and well names of the sentry well clusters and the Oceano CSD observation well cluster. The wells are divided into three basic depth categories: shallow, intermediate, and deep. Since initiation of the sentry well monitoring program, 20 quarterly events have been conducted with one each in May, August, and October 2009, and winter, spring, summer and fall 2010 through 2013, as well as January 2014 (the January 2014 data will be included in the 2014 annual report). These monitoring events include collection of synoptic groundwater elevation data and water quality samples for laboratory analysis. 4.1.2.2 Groundwater Levels Groundwater elevation data is gathered from the network of wells throughout the NCMA. Water level measurements in these wells were used to monitor effects of groundwater use, groundwater recharge, and as an indicator of risk of seawater intrusion. Analysis of these groundwater elevation data has included development of groundwater surface contour maps, hydrographs, and an index of key sentry well water levels over time (Figures 9 through 13). Contoured groundwater elevations for the Spring (April 2013) and Fall (October 2013) monitoring events, including data from the County of San Luis Obispo monitoring program, are shown on Figures 9 and 10. Figure 9 shows the Spring 2013 groundwater elevations were highest in the eastern portion of the NCMA and approximately 5 feet above sea level along the shore line. Of note is the development of a possible westward-facing trough that developed in the Spring in the northern part of the area, apparently in response to municipal pumping in the Arroyo Grande and Grover Beach area. A comparison with Spring 2012 contours shows that Spring 2013 water levels were generally 10 to 15 feet lower throughout the NCMA. Groundwater elevations in October 2013 (Figure 10) were again highest in the eastern portion of the NCMA. Water level elevations were approximately 2 to 5 feet above sea level along the shoreline. Groundwater elevations were generally above mean sea level (msl) throughout the NCMA during the October monitoring event, with the exception of some measurements in agricultural wells in the east-central part of the area where water level elevations were measured as deep as -6.7 feet msl. These lower water level elevations create and maintain the previously recognized depression in the water table in the so-called “pumping trough,” located south of the municipal well fields and in the vicinity of, and south of, lower Arroyo Grande Creek. Water elevations in this area are generally 5 to 10 feet lower than levels measured in Fall 2012. Item 11.a. - Page 52 NCMA 2013 Annual Monitoring Report April 28, 2014 (Project No. 04.62130129) 2013 NCMA Annual Report Final.Doc - 13 - Figure 11 shows hydrographs of selected wells from the County well monitoring program, illustrating long-term changes in groundwater levels in the NCMA. To provide geographic context, hydrographs from two wells located just east of the NCMA in the NMMA are also presented. The hydrographs for wells 32D03 and 32D11, and wells 31H08 and 31H09 (Figure 11) are paired hydrographs for wells south of and in the vicinity of the municipal well fields. Depending on duration of pumping of the municipal wells, water levels in these wells have historically been below levels in other areas of the basin for prolonged periods of time. Although the data sets are incomplete, the hydrographs show that, historically, groundwater elevations in these wells have generally been above mean sea level. However, an area of lower groundwater elevations (“trough”) beneath the active well field appeared during the period of reduced rainfall in 2007 and 2008. Although the presence of the trough has been relatively persistent, the water levels in this area have remained above sea level. Prior to 2013, groundwater elevations throughout the area recovered from the 2007-2008 lows and remained at levels similar to 2006 (a wet year). However, the very low rainfall year of 2013 resulted in water levels throughout the area declining 5 to 10 feet. The sentry well clusters are the essential tool for tracking critical groundwater elevation changes at the coast. Groundwater elevations in these wells are monitored quarterly as part of the sentry well monitoring program. As shown by the hydrographs for the five sentry well clusters (Figure 12), the sentry wells provide a long history of groundwater elevations. The deepest wells in the clusters (wells 24B03, 30F03, and 30N02) are screened at depths closely matching the screened depths of most local pumping wells. Hence, measured water elevations in these deepest wells reflect the net effect of changing groundwater recharge and discharge conditions in the primary production aquifer. Averaging the groundwater elevations from these three deep sentry wells provides a single, representative index for tracking the status and apparent health of the basin. Historical variation of this index is represented by the average deep sentry well elevations on Figure 13. Figure 13 clearly shows three years of drought (2007-2009) followed by recovery of the index values in subsequent years as rainfall increased and pumpage declined. The graph shows that the index values improved significantly since 2008 and remained above the 7.5-foot index until late April 2013. In April 2013 municipal groundwater pumpage was increased to replace temporarily unavailable supplies from Lake Lopez. As a result, the groundwater level in Sentry Well 30F03 declined by as much as 14 feet in 7 days and was below sea level for a total of 6 days (Figure 16). The rather dramatic decline in water level due to increased pumpage required almost two weeks to recover to the initial water levels observed prior to the increased pumping. Similar water level declines, albeit of less magnitude, were also observed in deep wells 24B03 and 30N02 (Figures 15 and 17, respectively). To provide more detail regarding seasonal and other groundwater level changes in the area between the NCMA and NMMA, detailed water level monitoring of well 32C03 was initiated in April 2012 and monitored throughout 2013. A sensor was installed to document long- and short-term changes in water level, temperature and electrical conductivity (EC). The acquired data indicates that water levels in Well 32C03 fluctuate on a daily basis by as much as one foot. The water level in well 32C03 declined between April 2012 (when the transducer was installed) Item 11.a. - Page 53 NCMA 2013 Annual Monitoring Report April 28, 2014 (Project No. 04.62130129) 2013 NCMA Annual Report Final.Doc - 14 - and September 2012 by 15 feet, then increased by 10 feet through February 2013. From February 2013 to early October 2013, water levels declined by about 15 feet. Since October 2013, water levels in the well increased about 6 feet; the most recent measurement in January 2014 shows a water level elevation of 6.7 feet (NAVD88). The water levels in the deep sentry wells at the four coastal locations (24B03, 30F03, 30N02, and 36L02) range from 1.33 feet to 7.52 feet lower at the end of 2013 than the water levels measured in January 2013 (Figures 15 through 17, Appendix A). As discussed earlier, the average elevation of the three deep wells has been used as a representative index of water levels in the main production zones. As shown on Figure 13, the index reflects both seasonal pumping and annual variations in the relationship between recharge and discharge. In October 2013 the average water elevation in the representative key wells was 6.31 feet, which is 1.19 feet below the adjusted “index” of 7.5 feet NAVD88. By the end of 2013, the average water elevation in the three-well index increased to 8.14 feet, which is above the index of 7.5 feet by 0.64 feet. As shown on Figure 13, the index remained below 7.5 feet between October 2007 and August 2009. The index water level increased to 7.37 in October 2009 and 9.65 in January 2010. As discussed in previous annual reports and shown in Figure 13, high levels of chloride (and sodium) in wells 30N02 and 30N03 occurred between May 2009 and January 2010. This relationship implies a lag in time between lowered water levels in the deep sentry wells and significant increases in sodium and chloride. This is potentially significant because Figure 13 shows that during April 2013 the calculated index level was as deep as 6 feet below the index value of 7.5 and remained at or below the index from early June 2013 until mid-December 2013. Furthermore, the water level elevation in Well 30F03 was below sea level for 6 days in late April. Continued average values below the index create a potential environment for increased risk of sea water intrusion. Additional observations include:  Water levels in the deep sentry wells reached their lowest level in 2012 in September of that year; the lowest levels observed in 2013 were observed in October.  Water levels in the deep sentry wells reached their highest levels of 2013 in February. From February to late November, water levels declined steadily; water level elevations in all the deep wells started increasing from late November 2013 through the end of the year.  Water levels in the deep wells showed significant effects of short-term increased local groundwater extraction in late April. Full recovery of the water levels following cessation of the short-term increased pumping did not occur until early June.  Although it is encouraging that the index value ended the year above the index, February through April is the time of year that is historically the highest value (at least since January 2010). The index value at the end of 2013 is 2 to 4 feet lower than the end of year levels of 2010 through 2012. If the wells experience a 1-foot rise through February to April followed by a 5-foot decline in water level elevations until October 2014 (as is typical in past years), then the index value may potentially be as low as 4 feet in October 2014. Considering the effects of any increased pumpage related to anticipated cutbacks in Item 11.a. - Page 54 NCMA 2013 Annual Monitoring Report April 28, 2014 (Project No. 04.62130129) 2013 NCMA Annual Report Final.Doc - 15 - surface water deliveries, the index level may approach the level seen in 2008-2009, just prior to observing the elevated chloride concentrations in the Pier Avenue well. 4.1.2.3 Water Quality Water is used in several ways in the NCMA, each use requiring a certain minimum water quality. Since contaminants from seawater intrusion or anthropogenic sources can potentially lower the quality of water in the basin, water quality is monitored at each of the sentry well locations in the NCMA and at County Monitoring Well #3. Four separate monitoring events occurred in 2013, with each piezometer in the sentry wells and in the Oceano CSD wells measured in January, April, July, and October 2013. During each event, the wells were all sampled in accordance with ASTM International Standard D4448- 01. The water quality data from these events and available historical data from these wells are presented in Appendix A. Because water quality trends are used to monitor for seawater intrusion, data collected in 2013 were added to previous data and the variation of selected constituents were plotted against time. Figures 19 and 20 show variation of chloride and TDS concentration, respectively, since 2009. The historic water quality data presented in Appendix A shows that water quality varied, sometimes widely, during the years 2009 through 2012. However, samples obtained in 2013 show very little change (variation) throughout the year and a general improvement in overall quality compared to 2009 (Figure 21). The NCMA 2009 Annual Monitoring Report suggested the observed historic variation in water quality data could be due to a number of factors, including variable permeability of geologic materials; potential mixing with seawater; ion exchange in clay- rich units; and variability in surface recharge sources such as Arroyo Grande and Meadow creeks. Changes in groundwater demand since 2009 and abundant rainfall in 2010-11 may have contributed to groundwater quality becoming relatively stable in the past few years. With the exception of shallow Wells 24B01 and 30N01, the 2013 data indicate no significant change compared to recent past measurements. Well 24B01 continues to show higher levels of TDS, chloride and sodium than the other wells in the monitoring network, and the data indicate a slight decrease in TDS and chloride but no change in sodium since the start of the year. TDS and sodium decreased slightly in 2013. A second shallow well, Well 30N01, shows a slight increase in TDS, sodium and chloride compared to the previous year. Water quality results in the well continue to exhibit concentration levels of TDS, chloride and sodium more in the range of other sentry wells. Sentry well cluster 32S/13E 30N (Pier Avenue) is located west of Highway 1 in Oceano and includes three piezometers. This sentry well cluster is just south of the “pumping trough” recognized in April 2013, and within the area of broad lowering of the water table recognized in October 2013 (Figures 9 and 10). The deep and intermediate level piezometers at this location showed low groundwater levels in 2008 and 2009 (NCMA 2008 and 2009 Annual Monitoring Reports, respectively). Data from this sentry well cluster was interpreted to indicate localized seawater intrusion affecting the deep zone (30N02) and, to a lesser extent, the middle zone (30N03) in 2009. Thus, water quality in the 30N well cluster is considered a key indicator of potentially encroaching seawater intrusion. Item 11.a. - Page 55 NCMA 2013 Annual Monitoring Report April 28, 2014 (Project No. 04.62130129) 2013 NCMA Annual Report Final.Doc - 16 - Data collected in 2010 from piezometers 30N03 and 30N02 show geochemical signatures of seawater intrusion on Schoeller geochemical plots (Figures 21 and 23, respectively). The Schoeller diagrams shown on Figures 21 through 25 are graphical representations of common cation and anion concentrations in water expressed in milliequivalents per liter (meq/l). Because several samples may be plotted on the same graph, variation in hydrogeochemical water characteristics may be easily recognized. This approach allows graphical, or visual, means to evaluate measured water quality against potential water sources. Each line of connected points illustrates the water quality signature from a specific well (e.g., 30N03, Figure 21) for a given sample period. For comparison, the Schoeller diagrams included here also show the typical geochemical signature for seawater (in black) and the typical signature for a groundwater basin water supply well (labeled “GW Base”, in blue). Most of the water quality samples plotted on the lower portion of the diagram are similar in shape to the groundwater basin sample and are combined within the shaded area. After the period of lower water level in the index wells in 2007 and 2008, wells 30N02 and 30N03 exhibited increased TDS, sodium and chloride in samples collected in 2009 (Figures 21 and 23). Beginning in 2010, both wells have shown lower TDS, sodium and chloride as well as a more narrow range in chemical variation (Figures 22 and 24). TDS, sodium and chloride values in the 2013 Q4 samples from both 30N02 and 30N03 showed only nominal changes compared to the previous year. The samples taken from the shallow completion well in this cluster (Well 30N01) continues to show somewhat elevated sodium and chloride; however it appears not to indicate sea level intrusion of the deeper levels that are screened in the groundwater production zone. This conclusion is based on the following related observations:  The well is shallow (screened from 15 to 40 feet), located near a coastal lagoon, and may be influenced by periods of high sea level or seasonal stagnation.  None of the deeper wells at any of the sentry well locations show high levels of TDS, sodium and chloride (indications of sea water intrusion).  Water levels of all deep wells generally exhibit a greater seasonal range than Well 30N01.  Compared to 2011, levels of TDS and most other measured water quality parameters declined through July 2012. Since then, these parameters have remained relatively stable as of the end of 2013. The shallow well in sentry well cluster 32S/12E 24B has historically contained brackish water. This sentry well is located in the northwestern corner of the basin in Pismo Beach. The shallow well (24B01) shows a similar geochemical signature (albeit muted) to that of seawater (Figure 25). Water samples from this well historically have shown high sodium and chloride concentrations. While these data have been interpreted by the California Department of Water Resources to be the result of a solution of residual marine and evaporative salts indigenous to the geologic environment in this part of the basin, it may be because the well is located near the lagoon at the mouth of Pismo Creek and is subject to storm surge and local flooding during storm and high sea conditions. The water sample from the shallow piezometer (24B01) showed elevated Cl and Na in October 2010 and all quarterly samples taken in 2011, 2012, and 2013 while samples from the two deeper piezometers had TDS, Cl, and Na levels that indicate no such effect. Item 11.a. - Page 56 NCMA 2013 Annual Monitoring Report April 28, 2014 (Project No. 04.62130129) 2013 NCMA Annual Report Final.Doc - 17 - These various water quality indicators described above suggest that the local interface/mixing zone between seawater and fresh groundwater remains seaward of the sentry wells. The location of the seawater interface is not known due to the heterogeneity of the aquifer. The only indication of the location of the interface would be when one or more monitored wells show an increase in TDS along with a geochemical signature resembling seawater. Based on experience in the NCMA, retreat of the interface may be reversed, and again become shoreward, if seaward gradients are reduced or reversed. These changes may be brought on by reduced recharge (e.g. drought conditions) or if pumping exceeds available groundwater supply, or both. Well 32C03 (County monitoring well #3) is located south and east of the main NCMA groundwater development area. It has exhibited little change compared to the initial sample taken in April 2012. Water in well 32C03 exhibits lower calcium, magnesium, and carbonates than all other wells and has a higher ratio of Na+Cl to CA+Mg+Carbonate. 4.1.3 Threats to Water Supply Because the NCMA depends on both local and imported water supplies, changes in either state-wide or local conditions can threaten the NCMA water supply. Water supply imported from other areas of the state may be threatened by State-wide drought, effects of climate change in the SWP source area, management and environmental protection issues in the Sacramento-San Joaquin Delta that affect the amount and reliability of SWP deliveries and risk of seismic damage to the SWP delivery system. Local threats to NCMA water supply similarly include extended drought and climate change that may affect the yield from Lopez Lake as well as reduced recharge to the NCMA (northern portion of the Santa Maria Groundwater Basin). In addition, the NCMA is not hydrologically isolated from the rest of the Santa Maria Groundwater Basin, and increased growth and excessive pumping on the Nipomo Mesa have contributed to a deepening groundwater depression underlying the NMMA.1 In addition, there is a potential impact from seawater intrusion if the groundwater system as a whole is not adequately monitored (as discussed in the above section) and managed. In particular the management of the basin may need to account for sea level rise and the relative change in groundwater gradient along the shore line as well as an ongoing imbalance between pumping and recharge in the NMMA (NMMA Technical Group. 2011). The ongoing drought has resulted in a lowering of groundwater levels throughout the NCMA, most notably in the agricultural production area and the upgradient (eastern) area represented by County Monitoring Well 3 (32-C). 4.1.3.1 Threats to State Water Project Supply Both extended drought and long-term reduction in snowpack due to climate change can affect deliveries from the State Water Project. California is entering the third year of a drought that has resulted in below-average precipitation and runoff in the SWP source area; in fact 2013 was the driest year on record. As a result, DWR has announced that storage in SWP reservoirs is low and deliveries for 2014 will be substantially reduced or even eliminated (as of January 31, 2014, DWR announced a reduction of Table A Allocation to zero percent). In addition to drought 1 To address the pumping in excess of local recharge and the growing groundwater depression in the NMMA, the Settlement Stipulation and Judgment require the NCSD to purchase and deliver a minimum of 2,500 acre-feet per year (AFY) of supplemental water to the Nipomo Mesa. Item 11.a. - Page 57 NCMA 2013 Annual Monitoring Report April 28, 2014 (Project No. 04.62130129) 2013 NCMA Annual Report Final.Doc - 18 - conditions, SWP pumping capacity was reduced as the result of a May 2007 federal court ruling to protect Delta smelt. These factors will directly reduce the allocation of water available to Pismo and OCSD through the SLOFCWCD in 2014. However, the threat of reduced delivery to local SWP users—Oceano CSD and Pismo Beach—has not fully materialized to date, as deliveries to certain areas in San Luis Obispo County continues to be approved in greater amounts than if the full SWP delivery reductions were occurring, in part because the SLOFCWCD is able to use some of its unallocated Table A amount to augment deliveries. The SLOFCWCD holds SWP allocation in addition to the amount needed to meet contracts with local agencies. This source of extra allocation may be used by service areas in San Luis Obispo County with SWP contracts such as Oceano CSD and Pismo Beach as a drought buffer to provide additional deliveries during years when full deliveries are not available. Nonetheless, in the future, the Delta’s fragile ecosystem, uncertain precipitation patterns and reduced snowmelt may further reduce California’s water supply reliability with potential ramifications for Oceano CSD and Pismo Beach. 4.1.3.2 Seawater Intrusion The NCMA is underlain by an accumulation of alluvial materials that slope gently offshore and extend for many miles under the ocean (DWR 1970, 1975). Coarser materials within the alluvial materials comprise aquifer zones that receive freshwater recharge in areas above sea level. If sufficient outflow from the aquifer occurs, the dynamic interface between seawater and fresh water will be prevented from moving onshore. Sufficient differential pressure to maintain a net outflow is indicated by onshore groundwater elevations that are above mean sea level and establish a seaward gradient to maintain that outflow. The 2008 Annual Report documented that a portion of the NCMA groundwater basin exhibited water surface elevations below sea level (NCMA 2008 Annual Monitoring Report). Hydrographs for NCMA sentry wells (Figure 12) show coastal groundwater elevations that were at relatively low levels for as long as two years. Such sustained low levels had not occurred previously in the historical record and reflected the impact of drought on groundwater levels. The low coastal groundwater levels indicated a potential for seawater intrusion. Increased TDS, Na and Cl concentrations were found in sentry well 32S/13E N03 in August 2009 and in 32S/13E N02 in August and October 20092. As documented in Section 4.1.2 of this report, groundwater elevations in July 2013 and October 2013 were significantly below groundwater elevations in July and October 2012. However they were above water level elevations measured in the same months in 2008 and 2009. Water elevation and water quality measurements in 2009 through October 2013 indicate the following:  Sentry wells in the cluster 32S/13E 30N may be relatively sensitive to seawater intrusion because of their location near Arroyo Grande Creek and the more permeable sediments 2 In addition to increased water levels beginning in 2010, well head modifications were made to all sentry wells in July 2011. Specifically, all well heads were raised above ground level. Prior to the modifications, the sentry wells including 30N piezometers were completed below land surface. The location and condition of the well heads raised concerns about the potential for contamination of samples. Item 11.a. - Page 58 NCMA 2013 Annual Monitoring Report April 28, 2014 (Project No. 04.62130129) 2013 NCMA Annual Report Final.Doc - 19 - deposited by the ancestral creek (NCMA 2009 Annual Monitoring Report) as well as the lower groundwater elevations typical to the east (Figures 9 and 10).  The initial portions of the seawater/groundwater interface were detected onshore at one site beginning with elevated chloride levels in May 2009; by October 2009 the interface had manifested in the middle and deep aquifer zones monitored by sentry wells 30-N02 and 30-N03. The extent to which seawater may have intruded other localized aquifer zones along the coast without being detected in the NCMA sentry wells is unknown due to heterogeneity of the aquifer and spacing of sentry wells.  Above average precipitation and decreased groundwater withdrawal in 2010 resulted in increased water levels in the sentry wells on a comparative seasonal basis and an apparent relief of the water table depression immediately south of lower Arroyo Grande Creek. Recent dry conditions in 2012 and 2013 have caused an overall lowering of water levels in the sentry wells and a resumption of the pumping depression that was recognized in 2009 (Figure 10).  In April 2013 groundwater extractions were increased in response to a short-term shutdown of the Lopez Lake delivery system for maintenance. At that time water levels in several sentry wells remained below normal for several weeks, and below sea level in sentry well 30F03 (Highway 1 deep well). The brief shutdown of Lopez Lake deliveries and increased groundwater pumping resulted in a short (one month) period when the deep well index was below the index standard of 7.5 feet. The index value recovered by late May 2013, but dipped below the 7.5-foot index again by late July 2013, where it remained until late December. As discussed previously, maintaining water levels above the 7.5-foot index is considered to create a sufficient gradient to avoid sea water intrusion.  Water quality in most wells remains similar to historic measurements but more importantly, showed no indication of the effects of seawater intrusion after the April pumping event or from the approximately 5-month month period when water levels were below the 7.5-foot deep well index. 4.1.3.3 Measures to Avoid Seawater Intrusion In recognition of the risk of seawater intrusion, the Northern Cities have developed and implemented a water quality monitoring program for the sentry wells and Oceano CSD observation wells, as described above. The Northern Cities, SLOFCWCD, and State of California have also worked cooperatively toward the protection of the sentry wells as long-term monitoring sites. Several measures are employed by the Northern Cities to reduce the potential for seawater intrusion. Specifically, the Northern Cities have voluntarily reduced coastal groundwater pumping, decreased overall water use via conservation, and initiated plans, studies and institutional arrangements to secure additional surface water supplies. As a result, each of the four major municipal water users reduced groundwater use between 25 and 90 percent between 2007 and 2010. In 2013, groundwater use ranged between 3 and 68 percent of the groundwater use in 2007. The deepening pumping depression within the NMMA appears to have reduced or eliminated the groundwater divide between the NCMA and NMMA. With the loss of this divide there has been a reversal of groundwater gradients and the development of a landward gradient in the southern portion of the NCMA. This landward gradient creates conditions favorable for Item 11.a. - Page 59 NCMA 2013 Annual Monitoring Report April 28, 2014 (Project No. 04.62130129) 2013 NCMA Annual Report Final.Doc - 20 - seawater intrusion in the NCMA and NMMA. To limit further increases in the risk of seawater intrusion, immediate measures must be made to reduce demand in the NMMA. Additionally, the County of San Luis Obispo, which possesses land use authority, must restrict any future development that increases water demand in the NMMA. 4.1.3.4 Change in Groundwater Recharge along NMMA Boundary Groundwater recharge to the NCMA includes subsurface flow from adjacent areas into the aquifers that supply water wells serving the NCMA. Historically an important source of subsurface recharge has been in-flow to the NCMA from the NMMA along the southeast boundary of the NCMA, previously estimated to be 1,300 AFY (DWR 2002). However, it appears that this inflow from the NMMA has been reduced to “something approaching no subsurface flow” due to lower groundwater levels in the NMMA (NMMA 2nd Annual Report CY 2009, page 43). This condition has continued to worsen through continued deepening and expansion of the depression in water level elevations in the inland portion of the NMMA. Contour maps prepared by DWR for spring 1975, 1985, 1995 and 2000 as well as Figures 6-5 and 6-6 from NMMA Annual Reports for Calendar Years 2010, 2011, and 2012, indicate a growing depression in water level elevations in the NMMA as a result of increased groundwater extractions, and recent data indicates that the depression continued to expand and deepen in 2013. The pumping depression creates a “transient groundwater divide” between the inland portion of the NMMA and the NCMA. As the groundwater depression continues to deepen and expand to the west and north, “the groundwater divide may dissipate, resulting in a lack of groundwater gradients from the inland portion of the NMMA toward the coast” (NMMA 5th Annual Report CY 2012). This potential reversal of groundwater gradients and the development of a landward gradient creates a condition favorable for seawater intrusion as well as reduces or eliminates a significant source of recharge to the NCMA water-producing zones. The NMMA 5th Annual Report CY 2012 (Figures 6-5 and 6-6) describes the presence of a persistent northwest/southeast-trending depression in water level contours in the northern portion of the NMMA. The NMMA 4th and 5th Annual Reports indicate that “there are a number of direct measurements that indicate that demand exceeds the ability of the supply to replace water pumped from the aquifers” (NMMA 4th Annual Report CY 2011 Finding 4, NMMA 5th Annual Report CY 2012, Finding 3). The NMMA projects an increasing water demand and groundwater use in the management area (NMMA 5th Annual Report CY 2012, page 32) and a growing deficit between supply and demand. Based on the reported groundwater extractions in the NMMA, it appears that groundwater pumping significantly exceeds the apparent dependable yield. Due to the ongoing imbalance between extraction and replenishment of aquifers in the NMMA, increased groundwater demand may lower water level elevations along the NMMA and NCMA boundary below current levels. Currently, the NMMA reports that the groundwater elevations near the “saddle” or transient divide between the NMMA and the NCMA are in the “range of several feet higher than adjacent areas” (NMMA 5th Annual Report CY 2012, page 40). However, water level data from County Monitoring Well #3 (32N03) shows that water levels in the area are declining, perhaps as much as 10 to 15 feet. As the historical subsurface inflow recharge from the NMMA to the NCMA declines (or is reversed), the agricultural users in the southeastern portion of the NCMA may see declining water levels, declining production capability, and conditions favorable Item 11.a. - Page 60 NCMA 2013 Annual Monitoring Report April 28, 2014 (Project No. 04.62130129) 2013 NCMA Annual Report Final.Doc - 21 - for seawater intrusion, as noted above (NMMA 5th Annual Report CY 2012). Although clearly exacerbated by the drought, the harbinger of these conditions was already observed in the water level data in the NCMA in October 2013, when water levels continued to decline in Monitoring Well #3 (32N03) and a pumping depression, with some water levels below sea level, appeared in the southeastern agricultural production area of the NCMA (Figure 10). 4.2 WATER DEMAND Water demand refers to the total amount of water used to satisfy various needs. In the NCMA, water is primarily used to satisfy urban demand and applied irrigation demand. The third category, rural demand, includes small community water systems, domestic, recreational and agriculture-related businesses, and has historically comprised a relatively minor component of the overall demand of the area. Table 6 (following page) presents water demands for urban uses, applied irrigation, and rural uses. Table 6. Total Water Demand (Groundwater and Surface Water, AFY) Year Arroyo  Grande  Grover  Beach  Pismo  Beach  Oceano  CSD  Total  Urban  Applied  Irrigation  Rural  Water  Total  Demand  2005 3,460 2,082 2,142 931 8,615 2,056 36 10,707  2006 3,425 2,025 2,121 882 8,453 2,056 36 10,545  2007 3,690 2,087 2,261 944 8,982 2,742 36 11,760  2008 3,579 2,051 2,208 933 8,771 2,742 36 11,549  2009 3,315 1,941 2,039 885 8,180 2,742 36 10,958  2010 2,956 1,787 1,944 855 7,542 2,056 38 9,636  2011 2,922 1,787 1,912 852 7,473 2,742 38 10,253  2012 3,022 1,757 2,029 838 7,646 2,742 41 10,429  2013 3,111 1,792 2,148 888 7,939 2,742 42 10,722  4.2.1 Urban Demand Urban water demands are presented in Table 6 for each of the Northern Cities from 2005 through 2013. These demand values reflect reported Lopez Lake and State Water Project (SWP) purchases and groundwater production data, and represent all water used within the service areas of the four agencies comprising Northern Cities, including the portions of Arroyo Grande and Pismo Beach that extend outside the NCMA (see Figure 2). The urban demand data include water delivered to municipal customers and all other water used by the respective municipal agency as well as system losses. Urban demand declined from 2010 to 2011, but has increased slightly each year for the past three years. Current urban demand is significantly below the demand levels experienced from 2005 through 2009. 4.2.2 Applied Irrigation Demand Applied Irrigation Demand (Table 6) is an in-direct measurement that requires a method for estimating Annual Gross Irrigation Water Requirement (AGIR). The San Luis Obispo County Item 11.a. - Page 61 NCMA 2013 Annual Monitoring Report April 28, 2014 (Project No. 04.62130129) 2013 NCMA Annual Report Final.Doc - 22 - Water Master Report uses a crop-specific method for calculating AGIR in acre-feet per year per acre (AFY/acre), based on crop ET, effective rainfall, leaching requirements, irrigation efficiency, and frost protection. Calculation of the AGIR, which is then used to estimate the applied water for irrigation for an aggregated area, is described in the following equation: AGIR (Ft) = [(Crop ET – Effective Rainfall) / ((1-Leaching Requirement) x Irrigation Efficiency)] + Frost Protection Water The calculated crop-specific applied water is multiplied by the specific crop acres to obtain the irrigation demand for a given crop type. The individual crop demands are then summed for the agricultural area of interest. In the NCMA, representative land use survey information that was utilized in the initial NCMA annual reports for calendar years 2008 and 2009 contained an estimate of agriculture water use based on acres aggregated by crop type. Recently, the San Luis Obispo County Agricultural Commissioners office (ACO) compiled an estimate of irrigated acres with spatial information, compatible for use in GIS. A view displaying the irrigated agriculture land for 2012 is presented as Figure 22; the 2012 compilation of irrigated lands for 2012 is considered representative of irrigated land conditions for 2013 because significant changes in agricultural land use have not occurred. The 2012 irrigated acres totaled 1,485 acres, about 7-percent less that reported in the NCMA 2008 Annual Monitoring Report. A visual observation comparing the views indicates the slightly lower amount of irrigated acres in 2012/2013 versus 2008/2009 is because the most recent survey recognizes roads and farmsteads within the agriculture area as unfarmed areas , thus, the total irrigated acreage is less. For comparison to the past reports, the water use in the NCMA 2012 Annual Monitoring Report was estimated based on the 1,485 acres identified by the ACO as irrigated land in 2012, multiplied by a representative annual water use value of (21.86 inches). The annual water use value was obtained from tables for Miscellaneous Field Crops and Strawberries, drip irrigation method, and a dry year, published by the Irrigation and Training Research Center (ITRC) in Cal Poly. In comparison, the two estimates differ by slightly more than 1-percent. The estimate based on the ACO acres and ITRC water use: 1,485 acres x 21.86 inches = 2,705 acre-feet. In comparison, the estimate based on the method used in the Todd (2007) report for a dry year was 2,742 acre-feet. Based on this comparison made in the NCMA 2012 Annual Monitoring Report, the method used to estimate agricultural water use for 2013 remains the same as for the previous annual report. The annual irrigation demand for the NCMA is represented by the aggregate of the crop acres by category multiplied by the estimated gross irrigation requirements per acre from the San Luis Obispo County Water Master Report (WMR). The WMR estimate of gross irrigation requirements varies by precipitation year type, including low, average, and high estimates of irrigation demand by crop type for each of the Water Planning Areas (WPAs) in the County. The range in estimated irrigation demands is based upon climatic conditions and average irrigation efficiency, and includes double cropping for the category truck crops. Because the WMR does not include gross irrigation requirements for turf grass, the values for pasture grass were applied to turf grass areas in the NCMA to estimate their applied Item 11.a. - Page 62 NCMA 2013 Annual Monitoring Report April 28, 2014 (Project No. 04.62130129) 2013 NCMA Annual Report Final.Doc - 23 - irrigation demand. The representative gross irrigation requirements for crop groups are presented in Table 7 (following page). As stated in the previous Annual Report, the areal extent of cultivated agricultural areas in the NCMA was quantified using a past land use survey by the ACO. Based on observation of the agricultural land use in views developed with recent land use survey information, the agriculture land use in the NCMA for 2013 has remained the same, consistent with previous years. Given this observation, the estimated agriculture acreage remains based on agriculture land use survey data and the previously applied methods. The areas with irrigated turf grass have been previously identified by public works personnel within the Northern Cities. The acreages of these areas have been measured from publically available aerial photographs using GIS software tools. Table 7. Gross Irrigation Requirement for WPA 5 by Crop Group Crop Type Low Annual Demand (AFY/acre) Average Annual Demand (AFY/acre) High Annual Demand (AFY/acre) Alfalfa 2.5 2.9 3.3 Nursery 1.4 1.7 2.1 Pasture 2.6 3.0 3.5 Turf Grass 2.6 3.0 3.5 Citrus 1.3 1.6 1.9 Deciduous 2.6 2.9 3.2 Truck (vegetable) 1.2 1.4 1.6 Vineyard 0.9 1.1 1.4 In the previous year estimates there were about 1,600 acres of irrigated agriculture within the NCMA of which approximately four acres are in nursery crops, and the remainder is truck crops such as broccoli, onions, and strawberries. Also identified was a combined total of 44 acres of irrigated turf grass at the Oceano Elementary School, Arroyo Grande High School, Harloe Elementary School, and the Le Sage Riviera Golf Course. For this evaluation, average irrigation efficiencies are assumed for the NCMA. Therefore, the annual irrigation demand for each crop type is assumed to be dependent only on that year’s precipitation and ET. For 2013, the annual precipitation and ET conditions indicate a Dry Year. The assigned year type for the demand estimates for all applied irrigation uses since 2004 are as follows:  Wet years: 2,056 AFY (2005, 2006, and 2010)  Average years: 2,397 AFY (2004)  Dry years: 2,742 AFY (2007, 2008, 2009, 2011, 2012, and 2013) Item 11.a. - Page 63 NCMA 2013 Annual Monitoring Report April 28, 2014 (Project No. 04.62130129) 2013 NCMA Annual Report Final.Doc - 24 - 4.2.3 Rural Demand In the NCMA, rural water demand refers to uses not designated as urban demand or applied irrigation demand and includes small community water systems, individual domestic water systems, recreational uses, and agriculture-related business systems. Small community water systems using groundwater in the NCMA were identified initially through review of a list of water purveyors compiled in the 2007 San Luis Obispo County Integrated Regional Water Management Plan (IRWMP). These include the Halcyon Water System, Ken Mar Gardens, and Pacific Dunes RV Resort. The Halcyon Water System serves 35 homes in the community of Halcyon, while Ken Mar Gardens provides water supply to 48 mobile homes on South Halcyon Road. The Pacific Dunes RV Resort, with 215 RV sites, provides water supply to a largely transitory population as well as a nearby riding stable. In addition, about 25 homes and businesses have been identified as served by private wells through inspection of aerial photographs of rural areas within NCMA. Irrigation of schools and parks from privately operated wells is included in the applied irrigation demand section. Two mobile home communities, Grande Mobile and Halcyon Estates, are served by Oceano CSD through the distribution system of Arroyo Grande, thus the demand summary of Oceano CSD includes these two communities. Based on prior reports, it is assumed that the number of private wells is negligible within the service areas of the four Northern Cities. The estimated rural water demand is shown in Table 8.

The years 2009 through 2013 have been consistently at or below the average which may be attributed to the relatively slower economy and conservation activities implemented by the Northern Cities. In the applied irrigation category, agricultural acreage has remained fairly constant. Thus, annual water demand for applied irrigation varies mostly with weather conditions. Acknowledging the variability due to weather conditions (see Table 6), applied irrigation water demand is not expected to Item 11.a. - Page 64 NCMA 2013 Annual Monitoring Report April 28, 2014 (Project No. 04.62130129) 2013 NCMA Annual Report Final.Doc - 25 - change significantly given the relative stability of applied irrigation acreage and cropping patterns in the NCMA south of Arroyo Grande Creek. Changes in rural demand have not been significant.

WATER DEMAND Table 4 (page 10) shows the Available Urban Water Supplies for each of the Northern Cities, with a total available urban water supply of 10,769 AFY. As discussed in Section 4, the 2002 Management Agreement estimated that the historical safe yield from the groundwater basin was 9,500 AFY. Because all of the irrigation applied water demand is supplied by groundwater, the total available applied irrigation supply is a portion of the estimated groundwater safe yield; this portion was allocated as 5,300 AFY for agricultural and rural use. The agricultural conversion of 330 AFY reduces this allocation to 4,970 AFY. Of the estimated safe yield of 9,500 AFY, other than what is allocated for applied irrigation and rural use, the remaining 4,200 AFY is allocated for urban water use (4,000 AFY) along with an estimated 200 AFY to subsurface outflow to the ocean. In 2012, the total urban water demand was 7,938.5 AF (Table 6), compared to the available urban water supply of 10,769 (assuming full delivery of SWP allocation). The estimated 2013 applied irrigation water use is 2,742 AF, and rural water use is estimated at 41.7 AF. The total estimated 2013 NCMA water demand was 10,722.2 AF (Tables 6 and 9). The water demand, by source, of each city and agency in 2013 is shown in Table 9.

The 120 AF of “Other Supplies” delivered to Arroyo Grande consists of groundwater pumped from the Pismo Formation, which is located outside of the shared groundwater basin. Based on the estimated groundwater safe yield, the total available supply for all uses is 15,699 AFY, which is the sum of 10,729 AFY for urban plus the allocation for applied irrigation and rural area of 4,970 AFY. Total 2013 NCMA water demand is estimated at 10,722 AF.

Management objectives and responsibilities were first established in the 1983 Gentlemen’s Agreement and updated in the 2002 Management Agreement. The responsibility and authority of the Northern Parties for NCMA groundwater management was formally established through the 2002 Settlement Agreement, 2005 Stipulation, and 2008 Judgment. Throughout the long history of collaborative management, which was formalized through the Agreement, Stipulation, and Judgment, the overall management goal for the Northern Cities is to preserve the long-term integrity of water supplies in the NCMA portion of the Santa Maria Groundwater Basin (SMGB). 6.1 MANAGEMENT OBJECTIVES Seven basic objectives have been established for ongoing NCMA groundwater management. Under each objective, the NCMA technical group has identified a number of strategies to meet the objectives. These strategies are listed and then discussed under each of the seven objectives listed below along with the history and rationale. Other potential objectives are outlined in the final section. The Northern Cities, both individually and jointly, are engaged in water resource management projects, programs, and planning efforts that address water supply and demand issues, particularly efforts to assure a long-term sustainable supply. Each section discusses major management activities during 2013. 6.1.1 Share Groundwater Resources and Manage Pumping Strategies:  Continued reduction of groundwater pumping, maintain below safe yield.  Coordinated delivery of Lopez Lake surplus water to maximize surface water supplies.  Continue to import State Water Project supplies to Oceano CSD and Pismo Beach.  Perform capacity assessments on the Lopez Lake and Coastal Branch pipelines to allow maximum current and future surface water imports.  Maintain surface water delivery infrastructure to maximize capacity. Discussion: A longstanding objective of water users in the NCMA has been to cooperatively share and manage groundwater resources. In 1983 the Northern Parties mutually agreed on an initial safe yield estimate (defined by DWR) and an allotment of pumping between the urban users and applied irrigation users of 57 percent and 43 percent, respectively. In this agreement the Northern Cities also established pumping allotments among themselves. Subsequently, the 2002 Management Agreement included provisions to account for changes such as ag land conversions. The agreements provide that any increase or decrease in the safe yield based on ongoing assessments would be shared on a pro rata basis. Pursuant to the stipulation the Northern Cities conducted a water balance study to update the safe yield estimate (Todd 2007). Item 11.a. - Page 67 NCMA 2013 Annual Monitoring Report April 28, 2014 (Project No. 04.62130129) 2013 NCMA Annual Report Final.Doc - 28 - Among other results, the parties agreed to maintain the existing pumping allotment among the urban users and established a consistent methodology to address agricultural land use conversion. In addition to cooperatively sharing and managing groundwater resources, the Northern Cities have coordinated delivery of water from Lopez Lake and have continued to import SWP water to maximize use of available surface water supplies. In 2013, Oceano CSD received its full allotment of SWP water and Pismo Beach imported nearly 50% of its allotment. These activities allow the Northern Cities, as a whole, to actively and effectively manage the groundwater resource. Although groundwater use in the NCMA has steadily, but slowly, increased since 2010, 2013 groundwater pumpage is less than any year during the 11-year period from 1999 through 2009. The water balance study (Todd 2007) highlighted the threat of seawater intrusion as the most important potential adverse impact to consider in managing the basin. Seawater intrusion, a concern since the 1960s, would degrade the quality of water in the aquifer and potentially render portions of the basin unsuitable for groundwater production (DWR 1970). A deep sentry well index of 7.5 feet (NAVD 88) has been recognized as the index, above which it is thought that there is sufficient fresh water (groundwater) outflow to prevent seawater intrusion. From late 2009 to April 2013, the Northern Cities management of groundwater levels and groundwater pumpage maintained the sentry well index above the 7.5-foot. level. However, for several weeks in April and May, and then again from early July through mid-December 2013, the index value dropped below the target. Another potential adverse impact of localized pumping includes reduction of flow in local streams, notably Arroyo Grande (Todd 2007). The Northern Cities (as Zone 3 contractors) have participated with SLOFCWCD in preparation of the Arroyo Grande Creek Habitat Conservation Plan (HCP) that addresses reservoir releases to maintain both groundwater levels and habitat diversity in the creek. Additional studies to finalize the HCP are scheduled for 2014. 6.1.2 Monitor Supply and Demand and Share Information Strategies:  Share groundwater pumping data at monthly NCMA Technical Group meetings.  Evaluate future water demands through comparison to UWMP projections. o Arroyo Grande 2010 UWMP o Pismo Beach 2010 UWMP o Grover Beach 2010 UWMP o Due to population, OCSD is not required to prepare an UWMP Discussion: Regular monitoring of activities that affect the groundwater basin, and sharing that information, has occurred for many years. The monitoring efforts include gathering data on hydrologic conditions, water supply and demand, and groundwater pumping, levels, and quality. The current monitoring program is managed by the Northern Cities in accordance with the 2005 Item 11.a. - Page 68 NCMA 2013 Annual Monitoring Report April 28, 2014 (Project No. 04.62130129) 2013 NCMA Annual Report Final.Doc - 29 - Stipulation and 2008 Judgment, guided by the July 2008 Monitoring Program for the NCMA. The monitoring data and a summary of groundwater management activities are summarized in the Annual Reports. Arroyo Grande, Grover Beach, and Pismo Beach have each evaluated their future water demands as part of their respective 2010 UWMP updates. The NCMA shares information with the two other management areas (NMMA and SMVMA) through data exchange and regular meetings throughout the annual report preparation cycle. The sharing of information has expanded as the management areas continue to work together. 6.1.3 Manage Groundwater Levels and Prevent Seawater Intrusion Strategies:  Utilize storm-water ponds to capture storm-water run-off and recharge the groundwater basin.  Install transducers in key monitoring wells to provide continuous groundwater elevation data; the following wells have transducers: o 24B01 o 24B03 o 30F03 o 30N02 o County Monitoring Well #3  Collect and evaluate daily municipal pumping data to determine impact on local groundwater elevation levels.  Continue to pursue IRWM Planning grant funding and other potential revenue sources to characterize the SMGB as basis for developing a groundwater flow model. Discussion: Prevention of seawater intrusion through the management of groundwater levels is essential to protect the shared resource. The NCMA agencies both increase groundwater recharge with stormwater infiltration as well as closely monitoring groundwater levels and water quality in sentry wells along the coast. Arroyo Grande and Grover Beach each maintain storm water retention ponds within their jurisdiction; the SLOFCWCD maintains the storm water system, including retention ponds, in Oceano. These ponds collect storm water runoff, allowing it to recharge the underlying aquifers. There are approximately 140 acres of detention ponds in Arroyo Grande and 48 acres of detention ponds in Grover Beach. The storm water detention pond in Oceano CSD is approximately one-half acre. Grover Beach modified its storm water system in 2012 to direct additional flow into one of its recharge basins. While closely related to the objectives to manage pumping, monitor supply and demand, and share information, this objective also specifically recognizes the proximity of production wells to the coast and the threat of seawater intrusion. The Northern Cities and SLOFCWCD have long cooperated in the monitoring of groundwater levels, including quarterly measurement by the Item 11.a. - Page 69 NCMA 2013 Annual Monitoring Report April 28, 2014 (Project No. 04.62130129) 2013 NCMA Annual Report Final.Doc - 30 - NCMA of groundwater levels in sentry wells at the coast. Upon assuming responsibility for the coastal monitoring wells, the NCMA became aware of the need to upgrade their condition. In July 2010 the well-heads (surface completions) at four sentry monitoring well clusters within the Northern Cities Management Area were renovated (Todd 2010). The modifications occurred at well clusters:  32S/12E-24B01, B02, B03;  32S/13E-30F01, F02, F03;  32S/13E-30N01, N02, N03; and  12N/36W-36L01, L02. The renovations included raising the elevations of the top of each individual well casing by two to three feet in order to reduce the risk of surface water entering the wells. Because the top of the well casing is used as the reference point for all depth to water measurements, the new surface completions were surveyed relative to the NAVD 88 standard in late September 2010 (Wallace Group 2010). The individual well casings have been raised above ground surface and protective locking steel risers now enclose each cluster. As a result of this work, the sentry wells within the NCMA are now protected from surface contamination and tampering. Quarterly measurement of groundwater levels aids in assessing the risk of seawater intrusion along the coast; to enhance the data collection and assessment efforts, the NCMA installed transducers in five of the key sentry monitoring wells to provide continuous groundwater levels at key locations. By combining this with the collection and evaluation of daily municipal pumping data, the NCMA is better able to determine the response of local groundwater levels to extractions and therefore better manage the basin. The fruits of these efforts with respect to observation of short-term responses to applied stresses in the basin through the collection of continuous groundwater levels are illustrated by the recognition of the sharp decline in groundwater levels at the coast in response to increased groundwater pumpage when Lopez Lake deliveries were temporarily suspended (see Section 4.1.2.2 and Figures 15-17). This short- term water level decline would not typically have been observed in the past when water levels were measured on a semi-annual or quarterly basis. In order to gain insight into water level fluctuation and water quality variation in the area between the NCMA and NMMA, a continuous monitor was installed in Well 32C03 (County Well #3). Well 32C03 was constructed and is owned by the County of San Luis Obispo and is part of their county-wide groundwater monitoring network. Well 32C03 is completed to 170 feet with a screened interval from 90 to 170 below ground surface and is constructed of 5-inch diameter polyvinyl chloride (PVC) casing. To provide more detail regarding seasonal and other groundwater level changes in the area between the NCMA and NMMA, detailed water level monitoring was initiated in April 2012. Sensors were installed to document long- and short-term changes in water level, temperature and specific conductance. The results from detailed monitoring of Well 32C03 are provided in Figure 18. Additional studies to enhance basin management efforts that have been discussed by the NCMA TG include: Item 11.a. - Page 70 NCMA 2013 Annual Monitoring Report April 28, 2014 (Project No. 04.62130129) 2013 NCMA Annual Report Final.Doc - 31 -  Implement a monthly water level elevation data analysis of the sentry wells during periods when the deep well index value is below the index target of 7.5 feet.  Implement a monthly analysis of electrical conductivity (EC) data from the wells with downhole transducers (24B01, 24B03, 30F03, 30N02, County Well #3) during periods when the deep well index value is below the index target of 7.5 feet to track potential water quality degradation. If EC data suggests water quality degradation, implement a monthly sampling and monitoring program.  Assess the potential impacts on sentry well water level elevations from extended periods of increased groundwater pumping by conducting analytical modeling analyses to predict water level responses given certain pumping scenarios. These analyses may prove fruitful as scenarios unfold regarding decreased SWP deliveries or short-term emergency cuts to Lopez Lake deliveries. Lastly, the 2005 Settlement requires NCSD and the other Mesa parties to import 2500 AFY to mitigate overpumping that has impacted groundwater inflow to the NCMA, and thus may facilitate seawater intrusion in both NCMA and NMMA. Although considerable progress in importing water has been made, overpumping on the Mesa continues and the terms and requirements of the Settlement have not been fulfilled. 6.1.4 Protect Groundwater Quality Strategies:  Perform quarterly water quality monitoring at all sentry wells and County Well #3.  Gather temperature and electrical conductivity data from five monitoring wells to continuously track water quality indicators for seawater intrusion.  Use IRWM Planning grant opportunities to characterize the groundwater basin as a basis for the development of a Salt and Nutrient Management Plan pursuant to State policy.  Utilize IRWM Planning grant funding to investigate alternatives for utilizing recycled water from the Pismo Beach and the South San Luis Obispo County wastewater treatment plants, including: o Development of a seawater intrusion barrier. o Recharge groundwater basin for indirect potable re-use. o Offset potable water pumping through agriculture/landscape irrigation. o Augment stream flow in Arroyo Grande creek. Discussion: The objective to protect groundwater quality is closely linked with the objective for monitoring and data sharing. To meet this objective all sources of water quality degradation, including the threat of seawater intrusion, need to be recognized. Water quality threats and possible degradation affect the integrity of the groundwater basin, potentially resulting in loss of use or expensive water treatment processes. Sentry wells are monitored quarterly and data from other NCMA production wells are assessed annually. The monitoring program includes Item 11.a. - Page 71 NCMA 2013 Annual Monitoring Report April 28, 2014 (Project No. 04.62130129) 2013 NCMA Annual Report Final.Doc - 32 - evaluation of potential contaminants in addition to those that might indicate seawater intrusion. Temperature and electrical conductivity probes have been installed in five monitoring wells to provide continuous water quality tracking for early indication of seawater intrusion. Additionally, NCMA efforts in conjunction with the NMMA have resulted in the ongoing efforts to characterize the groundwater basin in preparation for the possible development of a Salt and Nutrient Management Plan. 6.1.5 Manage Cooperatively Strategies:  Include the Santa Maria Valley Management Area (SMVMA) in the Santa Maria Groundwater Basin Management Areas (SMGB MA) Technical Subcommittee.  Coordinate groundwater monitoring data sharing and annual report preparation with the NCMA, NMMA and the SMVMA. Discussion: Since 1983, NCMA management has been based on cooperative efforts of the affected parties, including the Northern Cities entities, private agricultural groundwater users, San Luis Obispo County, the SLOFCWCD, and other local and state agencies. Specifically the NCMA agencies have limited their pumping and, in cooperation with SLOFCWCD, invested in surface water supplies so as to not exceed the safe yield of the NCMA portion of the SMGB. Other organizations participate, as appropriate. In addition to the efforts discussed in this report, cooperative management occurs through many other venues and forums, including communication by the Northern Cities in their respective public meetings, participation in the Water Resources Advisory Council (the County-wide advisory panel on water issues), and active participation in the ongoing IRWM Plan Update. The NCMA agencies participated in preparation and adoption of the 2007 San Luis Obispo County Integrated Regional Water Management Plan (IRWMP). The IRWMP promotes integrated regional water management to ensure sustainable water uses, reliable water supplies, better water quality, environmental stewardship, efficient urban development, protection of agriculture, and a strong economy. The IRWMP integrates all of the programs, plans, and projects within the region into water supply, water quality, ecosystem preservation and restoration, groundwater monitoring and management, and flood management programs. The SLOFCWCD received a DWR grant to update the 2007 Plan. Since the 2008 Judgment, the NCMA has taken the lead in cooperative management of its management area. The NCMA has also been a proactive participant in the Santa Maria Groundwater Basin Management Area technical subcommittee, which formed in 2010. These efforts continued throughout 2013. The NCMA Technical Group met monthly (at a minimum) throughout 2013. The group also met four times with the NMMA and SMVMA groups. The coordination among the management areas is leading to joint projects such as enhanced monitoring of groundwater levels and improved sharing of data. The NCMA meetings also provide for collaborative development of joint budget proposals for studies and plans as well as shared water resources (as discussed in Section 6.1.1 and 6.1.4). Item 11.a. - Page 72 NCMA 2013 Annual Monitoring Report April 28, 2014 (Project No. 04.62130129) 2013 NCMA Annual Report Final.Doc - 33 - In addition, the monthly meetings provide a forum for discussing the data collected as part of the quarterly monitoring reports (as discussed in Sections 6.1.2 and 6.1.3). A key water supply planning and management activity started in late 2013 by the NCMA is the initiation of joint Strategic Planning efforts for the purpose of providing the NCMA Technical Group with a framework for identifying common water resource planning goals and objectives, and to establish a 10-year work plan for implementation of those efforts. Several key objectives have been identified, including water supply reliability, increased outreach, and basin management. These efforts will continue throughout 2014 6.1.6 Encourage Water Conservation Strategies:  Share updated water conservation information  Implement UWMPs Discussion: Water conservation, or water use efficiency, is linked to the monitoring of supply and demand and the management of pumping. Water conservation reduces overall demand on all sources, including groundwater, and supports management objectives to manage groundwater levels and prevent seawater intrusion. In addition, water conservation is consistent with State policies seeking to achieve significant water use reductions by the year 2020. Water conservation activities in the NCMA are summarized in various documents produced by the Northern Cities, including the 2010 Urban Water Management Plans of Arroyo Grande, Grover Beach, and Pismo Beach. Due to the population of its service area, Oceano CSD is not required to prepare an UWMP or reduce water consumption by 20% by 2020; however the OCSD encourages water conservation and the installation of low flow fixtures. The Northern Cities implement water conservation activities to reduce water use and thus reduce groundwater demand. The Cities participate in a wide range of water conservation activities designed to educate the public on ways to reduce water use. City of Arroyo Grande The City of Arroyo Grande supports a part time water conservation coordinator staff position to manage existing conservation activities, encourage public participation, and create new conservation programs for the community. In the last 10 years, Arroyo Grande spent over $1,400,000 on water conservation efforts. Arroyo Grande is implementing the following water Demand Management Measures (DMMs):  Water Survey Programs (Equivalent program elements)  Residential Plumbing Retrofits  Water System Audits  Metering with Commodity Rates  Large Landscape Irrigation Programs  High-efficiency washing machine rebate programs Item 11.a. - Page 73 NCMA 2013 Annual Monitoring Report April 28, 2014 (Project No. 04.62130129) 2013 NCMA Annual Report Final.Doc - 34 -  Public information programs.  School education programs.  Conservation programs for commercial and institutional accounts.  Conservation pricing.  Water conservation coordinator.  Water waste prohibition.  Residential ultra-low-flush toilet replacement programs.  Cash for Grass. The water conservation efforts of Arroyo Grande have been successful; the DMMs that have been implemented have decreased water use per residential connection from 190 gallons per capita per day (gpcd) to 160 gpcd. The target per capita usage for 2015 is 167 gpcd, while the target per capita usage for 2020 is 149 gpcd. Continued implementation of these DMMs will help Arroyo Grande to reach its per capita water use goals and indicates the commitment Arroyo Grande has to optimizing use of its water supply. City of Pismo Beach The City of Pismo Beach is a member of the California Urban Water Conservation Council, and as such has developed best management practices (BMPs) to reduce water consumption and ensure reliable future water supply. Included in BMPs implemented by Pismo Beach are activities and programs that promote water conservation and sustainable use of water resources. BMPs that Pismo Beach is implementing or has equivalent coverage for are:  Water Survey Programs  Residential Plumbing Retrofit  Water System Audits  Metering with Commodity Rates  Landscape Irrigation Programs  Conservation Pricing  Water Conservation Coordinator  Ultra Low Flush Toilet Replacement The water conservation efforts of Pismo Beach have helped reduce residential water use from a high of 256 gpcd in 2007 to 226 gpcd in 2010. The 10-year baseline average water use is 236 gpcd. Continued implementation of these BMPs and implementation of other BMPs in the future will help Pismo Beach reach its per capita water use goals and indicates the commitment of Pismo Beach to optimizing use of its water supply. The target water use for 2015 is 214 gpcd; the target water use for 2020 is 192 gpcd. Item 11.a. - Page 74 NCMA 2013 Annual Monitoring Report April 28, 2014 (Project No. 04.62130129) 2013 NCMA Annual Report Final.Doc - 35 - City of Grover Beach As described in their 2010 Urban Water Plan, Grover Beach has developed and implemented Demand Management Measures to reduce water consumption and ensure a reliable future water supply. Included in the DMMs implemented by the Grover Beach are activities and programs that promote water conservation and sustainable use of water resources. DMMs that Grover Beach is implementing or has equivalent coverage are:  Water survey programs for single-family residential and multifamily residential customers  Residential plumbing retrofit  System water audits, leak detection, and repair  Metering with commodity rates for all new connections and retrofit of existing connections  Large landscape conservation programs and incentives  High-efficiency washing machine rebate programs  Public information programs  School education programs  Conservation programs for commercial, industrial, and institutional accounts  Conservation pricing  Water conservation coordinator  Water waste prohibition  Residential ultra-low-flush toilet replacement programs Grover Beach has implemented or is planning to implement all applicable demand management measures as part of the Water Conservation Program. The ongoing water conservation activities of Grover Beach include a “Cash for Grass” rebate, a water-efficient washing machine rebate program, and smart irrigation controller and sensor rebate program. The 10-year baseline average water use for Grover Beach is 140.7 gpcd. The target water use for 2015 is 127 gpcd, while the target water use for 2020 is 113 gpcd. 6.1.7 Evaluate Alternative Sources of Supply Strategies:  Evaluate expanded use of recycled water;  Analyze capacity of the Lopez Lake and Coastal Branch pipelines to maximize deliveries of surface water. The following analyses have been completed: o Lopez Pipeline Capacity Evaluation o Lopez Pipeline Capacity Re-Evaluation o Coastal Branch Capacity Assessment Item 11.a. - Page 75 NCMA 2013 Annual Monitoring Report April 28, 2014 (Project No. 04.62130129) 2013 NCMA Annual Report Final.Doc - 36 - Discussion: The Northern Cities continue to evaluate alternative sources of water supply which could provide a more reliable and sustainable water supply for the NCMA. An expanded portfolio of water supply sources will support sustainable management of the groundwater resource and help to reduce the risk of water shortages. These alternative sources include: State Water Project Oceano CSD and Pismo Beach are currently SWP customers and could utilize additional water deliveries. Pismo Beach has increased its SWP allocation by securing a “drought buffer” to increase the availability of supply during periods of SWP shortfalls. Grover Beach and Arroyo Grande are not SWP customers. Water Recycling In 2010, the South San Luis Obispo County Sanitation District (SSLOCSD) updated their 2001 evaluation of recycled water opportunities. The new evaluation included an evaluation of using disinfected secondary treated water to irrigate landscaping and the potential use of recycled water if the SSLOCSD Waste Water Treatment Plant (WWTP) were upgraded to provide tertiary treatment. By providing tertiary treatment, as much as 189 AFY of potential demand could be satisfied. The City of Pismo Beach also has evaluated use of recycled water. As described in the 2010 UWMP, “the City may begin regional planning efforts regarding recycled water within the next five years”. The City of Pismo Beach is considering plans to upgrade its waste water treatment plant to provide an anticipated recycled water supply of up to an estimated 1,558 AFY in 2015. This estimate provides an idea of the amount of recycled water that could be available. The City of Pismo Beach UWMP anticipates that the recycled water not used for irrigation near the WWTP and in the Price Canyon development area “may be applied towards groundwater recharge operations.” New funding through the county IRWM Plan update will allow additional progress in water recycling in the NCMA. Lopez Lake Expansion In 2008, San Luis Obispo County sponsored a preliminary assessment of the concept of installing an inflatable rubber dam at the Lopez Dam spillway. Subsequently, the SLOFCWCD Service Area 12 and the Cities of Arroyo Grande, Grover Beach and Pismo Beach funded a study to further analyze the feasibility of increasing the yield of Lopez Lake by raising the spillway height with an inflatable dam or permanent extension. The study was finalized in 2013 and identified the potential to increase the annual yield from the lake by 500 AFY with a spillway height increase by 6 ft (Stetson 2013). The NCMA agencies are continuing to evaluate other aspects of the project, including pipeline capacity and impacts on the HCP process (Stetson. 2013). Desalination In 2006, Arroyo Grande, Grover Beach, and Oceano CSD utilized Prop 50 funds to complete a feasibility study on desalination as an additional water supply option for the NCMA. This alternative supply is not considered to be a viable option at this time.

Boundary Maps Appendix B. Related Organizations Appendix C. NCMA TG Initiatives 2 BACKGROUND The Northern Cities, comprised of the Oceano Community Services District and the Cities of Arroyo Grande, Grover Beach and Pismo Beach, have a long history of cooperative management of their shared water resources, and continue to actively work together to manage groundwater and surface water supplies for a population of approximately 46,000 residents and hundreds of thousands of visitors each year. The service areas for each of the Northern Cities are shown in Appendix A. The Northern Cities initiated collaborative management of the Santa Maria Groundwater Basin (SMGB) in 1983, with the development of the Agreement Regarding Management of the Arroyo Grande Groundwater Basin (Gentlemen’s Agreement). The Gentlemen’s Agreement defined the safe yield for the Northern Cities portion of the SMGB and allocated the available water to the urban and agricultural users. Fin a l D r a f t Item 11.a. - Page 144 Northern Cities Management Area Technical Group Mission Statement Final Draft Strategic Plan 2 In 1997, the SMGB became subject to litigation and in 2002 the Northern Cities, the Northern Landowners, and Other Parties entered into a Settlement Agreement, which reaffirmed the Gentlemen’s Agreement. Subsequently, the Northern Cities and other Parties entered into the 2005 Stipulation, which formally divided the SMGB into three management areas: the Northern Cities Management Area (NCMA); the Nipomo Mesa Management Area (NMMA); and the Santa Maria Valley Management Area (SMVMA). The boundaries of each of the management areas are shown in Appendix A. The Superior Court of California later adopted the Stipulation in its January 25, 2008 Judgment After Trial (Judgment). On November 21, 2012, the California Court of Appeal (Sixth Appellate District) upheld the Superior Court’s Judgment. The California Supreme Court later refused to hear the case – upholding the Appellate Court’s decision. The Stipulation requires that each Management Area develop a monitoring program that must include data collection and monitoring sufficient to determine land and water uses within the management area, sources of supply to meet those uses, groundwater conditions including groundwater level and quality, the amount and disposition of Developed Water supplies, and the amount and disposition of other sources of water supply. This information must be presented to the Court in an annual report that summarizes the results of the monitoring program, changes in groundwater supplies and any threats to groundwater supplies. In 2009, the Northern Cities formed the Northern Cities Management Area Technical Group (NCMA TG), comprised of technical staff from each of the agencies and selected consultants, to coordinate their efforts for the monitoring program and the annual report. As part of their collaborative management, the Northern Cities split the costs for the monitoring program, the annual report and staff extension services, based upon each agency’s percentage of the groundwater basin safe yield. The NCMA TG’s operating budget for these tasks is approximately $200,000 per year. The overall annual budget varies year to year based upon the different initiatives pursued by the NCMA TG. In addition to the preparation of the Annual Report, the NCMA TG works collaboratively with the other jurisdictions and regional groups to manage water supplies within southern San Luis Obispo County. Appendix B outlines the NCMA TG’s relationship with the related agencies, groups, committees, organizations, agreements and initiatives. In coordination with the other regional groups and on its own, the NCMA TG actively pursues opportunities to enhance the sustainability of water supply resources within the NCMA. A summary of complete and ongoing NCMA TG initiatives is provided in Appendix A. 3 MISSION STATEMENT The NCMA TG developed the following Mission Statement to help guide ongoing initiatives and to capture the requirements outlined in the Gentlemen’s Agreement, Settlement Agreement and the Stipulation: Preserve and enhance the sustainability of water supplies for the Northern Cities Area by:  Enhancing supply reliability  Protecting water quality  Maintaining cost-effective water supplies  Advancing the legacy of cooperative water resources management Fin a l D r a f t Item 11.a. - Page 145 Northern Cities Management Area Technical Group Objectives of the NCMA TG Final Draft Strategic Plan 3 4 OBJECTIVES OF THE NCMA TG Through the strategic planning process, the NCMA TG identified several key objectives to guide future efforts. These objectives include: 1. Enhance Water Supply Reliability o Prepare the Northern Cities for prolonged drought conditions o Develop coordinated response plan for salt water intrusion and other supply emergencies o Analyze impacts of pumping on the groundwater basin o Better protect against threats to groundwater sustainability 2. Improve Water Resource Management o Update the 2002 Settlement Agreement o Develop more formalized structure/governance for the NCMA TG 3. Increase Effective Outreach o Engage agriculture stakeholders o Improve coordination with SLOCFC&WCD and other regional efforts o Increase communication with City Council & Board of Directors 5 STRATEGIC INITIATIVES The NCMA TG utilized a screening and objective ranking process to develop prioritized strategies for improving the sustainability of water resources in the NCMA. Initially the TG developed a list of potential initiatives to consider during the screening process. Subsequently, the TG developed seven (7) criteria to rank the initiatives. Utilizing these criteria, each of the initiatives was ranked independently on a scale from one (low score) to three (high score). Upon completion of the independent scoring and prior to reviewing the results, weighting factors were applied to each of the evaluation criteria. The combination of the ranking for each criteria and the weighting factor for that criteria were then utilized to develop the scoring for each initiative. Table 1 lists the Evaluation Criteria and the Weighting Factors utilized for the strategic initiative screening. Table 1. Evaluation Criteria Evaluation Criteria Weighting Factor Reliability Enhancement 3 Cost Effectiveness 2 Enhanced Management 3 Jurisdictional Alignment 1 Outside Stakeholder Interest 1 Feasibility 2 Sustainability 3 After the initial ranking was completed, the initiatives were grouped based on common strategies and then sequenced according to the order that they would need to be completed in. Table 2 lists the key strategies developed by the NCMA TG.
