The Initial Study includes staffs on-site inspection of the project site and surroundings and a detailed review of the information in the file for the project. In addition, available background information is reviewed for each project. Relevant information regarding soil types and characteristics, geologic information, significant vegetation and/or wildlife resources, water availability, wastewater disposal services, existing land uses and surrounding land use categories and other information relevant to the environmental review process are evaluated for each project. The Community Development Department uses the checklist to summarize the results of the research accomplished during the initial environmental review of the project. Persons, agencies or organizations interested in obtaining more information regarding the environmental review process for a project should contact the City of Arroyo Grande Community Development Department at 214 East Branch Street Arroyo Grande, CA 93420 or call (805) 473- 5420. A. PROJECT DESCRIPTION: Proposal to extend the existing City roadway known as Castillo Del Mar to improve circulation around the southeast portion or Arroyo Grande High School campus and adjoining residential neighborhood. Castillo Del Mar will be extended from its present terminus to Valley Road to serve the existing Vista Del Mar development located within the City limits and the J.H. Land Partnership proposed development located within the unincorporated area of San Luis Obispo County. The proposed roadway extension will traverse the Lucia Mar Unified School District (LMSD) property for the existing Arroyo Grande High School site (APN 006-095-001)and a portion of a private agricultural parcel owned by John Taylor(Assessor's Parcel No. 006-095-002). The project includes the following components: • 1) Tentative parcel map for an approximate 50-acre property including and southeast of Arroyo Grande High School campus to create a 37-acre parcel (existing Arroyo Grande High School campus) and an 11-acre parcel and to rezone a 10-acre portion (existing sports fields and parking lots)of the 37-acre parcel from Agriculture to Public Facilities (identical to the zoning for the remainder of the Arroyo Grande High School campus); and amend the 2001 General Plan Land Use Element to re-designate the 11-acre proposed parcel from Community Facilities to Low Density Single Family Residential and to rezone the 11-acre proposed parcel from Agriculture (Ag) to Residential Hillside (RH)[See Attachment A]; 2) Subdivide an approximate 7.5 acre parcel adjoining and south of Arroyo Grande High 'School campus on the east side of Valley Road to create a 1.2-acre parcel and a 6.3-acre parcel and amend the 2001 General Plan Land Use Element to designate the 1.2-acre parcel from Agriculture to Community Facilities and rezone the 1.2—acre parcel from Agriculture (Ag)to Public Facility(PF); 3) To design, construct, extend and Improve Castillo Del Mar Drive from near Orchard Street to Valley Road to enable circulation around Arroyo Grande High School and allow local street access southeast to a proposed County subdivision known as Busick Tract No. 1789 located outside City limits; 4) To accept an in-lieu mitigation contribution for loss of one acre of prime farmland associated with proposed road extension and potential conversion of prime.farmland to future Public Facility use. Design and review of any subsequent residential subdivision is not part of the project and therefore any future development is subject to separate discretionary and environmental review. This initial Study evaluates potential environmental impacts for the proposed amendments to the Land Use Element and Zoning maps that are intended to provide consistency between the General Plan and Zoning Ordinance, the General Plan and Zoning amendments that are related to the Tentative Parcel Map and land use changes associated with the proposed construction of Castillo del Mar, as well as the proposed road extension and improvements.

ENVIRONMENTAL ANALYSIS During the Initial Study process, several issues were identified as having potentially significant environmental effects (see following Initial Study). Those potentially significant items associated with the proposed project can be minimized to less-than-significant levels by incorporating the mitigation measures listed below. All mitigation measures contained in this initial Study shall be included in the Conditions of Approval for the project.

The project includes approximately 11.6-acres of undeveloped hillside behind the Arroyo Grande High School sports fields and student parking area which is proposed for disposition and rezoning from Agriculture (A)to Residential Hillside(RH). An existing roadway, Castillo del Mar Drive, and a connecting segment currently used for emergency access,would be improved as a public street right-of way and offered for dedication. Additionally, the roadway improvement includes a 44 ft. wide roadway extension, that is 987 lineal ft. for Castillo Del Mar from its current terminus, along the southern edge of the Arroyo Grande High School campus, and extended In an "S" curve to intersect Valley Road (Attachment A). Additionally, approximately one-acre of prime farmland including the proposed road extension, immediately adjacent the Arroyo Grande High School is proposed to be re- designated and rezoned from Agriculture to Community Facility/Public facility. Both the 11.6 acres of vacant hillside and the area east of Valley Road through which the Castillo del Mar Drive is proposed to be extended, are open to public view. -Impact. Policy C/OSI-1 of the Agriculture, Conservation and Open Space Element of the General Plan encourages protection of visually accessible scenic resources. A 'scenic resource' is further defined as "agricultural land, open spaces, hillsides, ridgelines, canyons, valleys, landmark trees, woodlands, wetlands, streambeds and banks, and well as aspects of the built environment that are of a historic nature, unique to the City, or contribute to the rural, small town character of the City? The City has not officially recognized this property as being a sensitive scenic resource, and the road extension will only traverse vacant and farmed agricultural land for approximately 100 feet. Since the road extension crosses property at the bottom of a moderately sloped parcel and along the periphery of existing parking lots for Arroyo Grande High School, it is not expected that the road extension will cause a significant aesthetic impact. The 11.6 acres proposed to be re-designated and rezoned to Residential Hillside (RH) are surrounded on three sides by.RH zoning, which includes the Vista del Mar subdivision to the east. This proposal would enable future subdivision application, subject to project-specific environmental review, for a maximum of eight residences, exclusive of possible density bonuses for affordable housing.

AGRICULTURAL RESOURCES Significant Impact can Insignificant Not - Will the project: &will be Impact Applicable mitigated a) Convert prime agricultural land to [� ® [� ❑ non-agricultural use? b) Impair agricultural use of other property or result in conversion to other uses? c) Conflict with existing zoning or • ® D [] Williamson Act program? d) Other fl LI Setting. Both the 11.6-acre hillside portion of the project and the Arroyo Grande High School sports fields (approximately 10 acres) have conflicting zoning and General Plan classifications. The General Plan classification is Community Facilities (CF)and the zoning district is Agriculture. This conflict was documented in the City's study on Agricultural Resources (2003), and determined that the General Plan designation for this parcel was not inconsistent or in need of modification, and therefore the zoning would be changed from Agriculture to PF during the Development Code Update process to City of Arrovo Grande,Initial Study for GPA06-001;DCA06-001; TPM 06-004 Page 5 address changes required by the 2001 General Plan update (not yet complete). Therefore the change in zoning from Agriculture for the 10-acre sports fields and the 11.6-acre vacant hillside area is not considered a conversion of prime agricultural land due to it's consistency with the designation as CF in the 2001 General Plan, review under the 2001 General Plan EIR and subsequent analysis in the 2003 Report on Agricultural Resources (including it's non-prime classification as class IV--VI soils according to the USDA Soil Survey of San Luis Obispo County). However, the proposed General Plan and Zoning Amendments for the 1.2 acre portion of John Taylor's 7.5-acre parcel (APN 006-095- 001), currently in row crop production, from Agriculture to Community Facilities/PF is considered a conversion of prime agricultural land. • impact. Due to the proposed re-zoning and conversion of 1.2 acres of irrigated and farmed agricultural land, the impact must be considered significant unless it can be determined that in consideration of all the implications of the conversion, there is feasible mitigation that can reduce the impact to less than significant. The General Plan Agricultural, Conservation and Open Space Element objective Agi requires the City to "Avoid and/or mitigate loss of prime farmland soils and conserve non-prime Agriculture use and natural resource lands." Several policies and implementation measures specifically relate to loss of the City's agricultural land inventory and must be considered In light of the specifics of the proposal in order to determine if the impact can be mitigated to the extent that it is no longer significant or if it remains significant even after all applicable mitigation is required. Given that the proposal includes the improvement, extension and dedication of a public road to address a circulation deficiency, Ag1-1.2 relates to the proposed action as it states: "Public facilities are permitted on agricultural and natural resource lands when required by public health, safety and welfare of the public". Adequate and safe circulation and secondary access around the high school is an applicable application of this policy and provides for consideration of mitigation if the potential conversion can not be fully avoided due to public health safety and welfare. • Additionally, the proposed conversion of 1.2-acres of agricultural land is located a triangular piece of property between the Arroyo Grande High School campus and Valley Road, and as such it is not anticipated that it will fragment or impair other agricultural lands. Since nearly the entire proposed 1.2-acre parcel would be included within 100 ft. of operational farmland, there could not be any residential development on the property, consistent with the City's agricultural buffer requirements in Section 16.12.170.E. General Plan policy Ag1-4 and related policies include provisions for mitigation which may include permanent protection of prime farmland soils at a ratio of at least 1:1 with regard to the acreage of land removed from the capability for agricultural use which may be satisfied by payment of in-lieu fees as proposed. Development Code provisions suggest up to a 2:1 mitigation of comparable Ag capability. Mitigation/Conclusion. MM 2.1: Payment of an in-lieu fee sufficient to provide for the permanent protection of comparable farmland for the 1.2-acre conversion. The General Plan indicates mitigation fees of comparable farmland at a ratio or 1:1, however the City's Development Code requires mitigation fees at a ratio of up to 2:1 to be used for acquisition of a farmland conservation easement of farmland deed restriction in accordance with Section 16.12.170. Proposed mitigation fees are consistent with the 2:1 ratio. Responsible Party: Developer Monitoring Agency: City of Arroyo Grande CDD Dept.

Any future projects that may utilize the road extension will be evaluated under CEQA for any potential impacts. The proposed road connection would be constructed along the periphery of existing parking lots for Arroyo Grande High School and would not subject individuals to objectionable odors or expose any sensitive receptors to substantial air pollutant concentrations. Short-term impacts related to dust generation from grading would result in dust generation that could affect adjacent properties. Mitigation measures placed on the project would reduce short-term dust generation during construction of the project to less-than-significant levels. The dust control measures listed below shall be followed during construction of the project, and shall be shown on grading and building plans. rfti of Arroyo Grande, Initial Study for GPA06-001;DCA06-001; TPM 06-004 Page 7 Mitigation/Conclusion. The following mitigation measures are necessary to reduce potential air quality impacts from construction to a less-than-significant level. • '` The project shall comply with all applicable Air Pollution Control District (APCD) regulations • pertaining to the control of fugitive dust (PK()) as contained in section 6.5 of the Air Quality Handbook. All site grading and demolition plans shall list the following regulations: MM 3.1: All dust control measures listed below (MM 3.2 — 3.6) shall be followed during construction of the project and shall be shown on grading and building plans. The contractor or builder shall designate a person or persons to monitor the dust control program and to order increased watering, as necessary, to prevent transport of dust off site. The name and telephone number of such person(s)shall be provided to the APCD prior to map recordation and grading of the road improvement and extension. MM 3.2: During construction, water trucks or sprinkler systems shall be used to keep all areas of vehicle movement damp enough to prevent airborne dust from leaving the site. At a minimum, this would include wetting down such areas in the later morning and after work is completed for the day and whenever wind exceeds 15 miles per hour. Reclaimed (non-potable) water should be used. MM 3.3: Soil stockpiled for more than two days shall be covered, kept moist, or treated with soil binders to prevent dust generation. MM 3.4: All vehicles hauling dirt, sand, soil, or other loose materials are to be covered or should maintain at least two feet of freeboard (minimum vertical distance between top of load and top of trailer)in accordance with CVC Section 23114. MM 3.5: Install wheel washers where vehicles enter and exit unpaved roads on to streets, or wash off trucks and equipment leaving the site. Vehicle speed for all construction vehicles shall not exceed 15 mph on any unpaved surface at the construction site. MM 3.6: Sweep streets at the end of each day if visible soil material is carried on to adjacent paved roads. Water sweepers with reclaimed water should be used where feasible. MM 3.7: All off-road and portable diesel powered equipment, including but not limited to bulldozers, graders, cranes, loaders, scrapers, backhoes, generator sets, compressors, auxiliary power units, shall be fueled exclusively with California Air Resources Board (ARB) motor vehicle diesel fuel. MM 3.8: Diesel construction equipment shall meet the ARB's 1996 certification standard for off-road heavy-duty diesel engines.

The proposed road improvements and extension include an area of paved roadway that is currently used for emergency access. The area of land that will be included in the portion of the roadway widening is currently roughly graded and includes an area used for storage containers. The proposed roadway extension will traverse about 200 feet across a portion of the 1.2 acre agricultural parcel currently in row crop production. There is a seasonal drainage ditch that traverses the AGHS campus between sports fields and connects to the proposed 1.2-acre Public-Facilities parcel. However, the proposed road construction will occur in the area where there is existing crop production and avoids the area where there is some evidence of native vegetation (the drainage ditch is dug seasonally in the crop area for flood protection.) Impact. It is not anticipated that there will be any impact to biological resources due to the project construction because the area of proposed construction does not include special habitat or important vegetation. Any future development of the proposed 11.6-acre residential hillside parcel will be subject to site-specific environmental review. ••5.

The nearest recorded archaeological site is located approximately 2,500 feet southwest of the project site near Los Berros Creek, However, immediately south of the project site on the Haddox property, an unrecorded site exists. • (itv of Arroyo Grande, Initial Study for GPA06-001;DCA06-001; TPM 06-004 Page 9 Impact. The assessment for the 1990 Vista Del Mar EIR included a surface examination of the off- site area that indicated that no part of the project site extends into the vicinity of the archaeological site. Further, a thorough field reconnaissance of the project site revealed no surface evidence of the prehistoric or early historic occupation or use of the site, and that the soils and geological conditions of the site Indicate that the likelihood of the project site is not anticipated to have any direct impact on local archaeological/cultural resources. Mitigation/Conclusion. Although it is not anticipated that there are any impacts to archaeological/cultural resources, implementation of the mitigation measure(s) listed below will ensure that no impacts will occur. MM 5.1: In the event that prehistoric cultural materials, or historic cultural materials are encountered, work in the immediate vicinity of the finds shall be suspended and a qualified archaeologist and representative from the Northern Chumash Tribal Council allowed to quickly record, collect, and analyze any resources encountered. The City shall be notified should resources meeting CEQA significance standards be discovered. The Chumash representative and archaeologist shall work as quickly as possible to permit resumption of construction activities. It is preferred that location data of finds be recorded using a hand-held global positioning system (GPS) receiver. In the event that human remains (burials)are found,the County Coroner(781-4513)shall be contacted immediately. - if the coroner determines that the remains are not subject to his or her authority and if the coroner recognizes the remains to be those of a Native American, or has reason to believe that they are those of a Native American, he or she will contact by telephone within 24 hours the Native American Heritage Commission.

The site has varying topographical gradients with an approximate 2 -- 9% northwestern — facing slope. There is a seasonal drainage ditch that traverses the existing AGNS sports fields. Undisturbed vegetation consists primarily of grasses. According to the 1990 EIR for Vista Del Mar, the project area lies on a northwest—facing slope Impact. A major source of potential earthquake damage to Arroyo Grande is from activity along the regional San Andreas Fault located less than forty (40) miles east along the eastern border of San Luis Obispo County. The most widespread intensity of ground shaking depends on several factors including the magnitude of the earthquake, the distance from the earthquake epicenter, and underlying soil conditions. Other regional faults of significance that could affect the project area in terms of ground shaking are the Rincondada and Nacimiento faults, located approximately twenty-five '.(25) miles east of the City. These faults are considered "potentially active", and could cause moderate (Magnitude 6.0+) earthquakes in the area. The West Huasna fault is located roughly three (3) miles east of the City of Arroyo Grande. The project site would be subject to severe ground shaking in a strong seismic event,.which could cause damage to structures and endanger public safety. The project site will be subject to soil erosion and downstream sedimentation during construction and after project completion. Specific erosion control requirements are specified below under the Hydrology and Water Quality section. Mitigation/Conclusion, Seismic hazard, soil stability, soil erosion and downstream sedimentation are considered potentially significant impacts that can be reduced to a less-than-significant level with implementation of the mitigation measures listed below.

Existing ambient noise in the vicinity of the project site is primarily generated by vehicular traffic and adjacent agricultural operations. Impact. The project is expected to generate loud noise during construction that will impact the adjacent school site and residences. This is considered a potentially significant impact that can be mitigated to a less-than-significant level with implementation of the below mitigation measures. Mitigatlen/Conclusion. The project will generate short-term noise impacts with construction activities that require mitigation. Long-term increases in traffic and other operational noise levels are considered less-than-significant Impacts and no mitigation measures are necessary.- MM 8.1: Construction activities shall be restricted to the hours of 8 a.m. and 6 p.m. Monday through Saturday. No construction shall occur on Sunday. On-site equipment maintenance and servicing shall be confined to the same hours. MM 8.2: All construction equipment utilizing internal combustion engines shall be required to have mufflers that are in good condition.

The proposed road connection was originally anticipated when the Vista del Mar subdivision was built as a preferred circulation alternative instead of Orchard Ave. Castillo del Mar will enable access to a potential low density (maximum of 7- units) subdivision on the proposed 11.6-acre residential hillside parcel. Impact. The proposal addresses a•long-term circulation deficiency for AGNS and surrounding residences. Although the project will enable access to a potential future subdivision, its potential for increased traffic is less than ten peak-hour trips, and thus the road improvement is not considered to . induce substantial growth In the vicinity. The project will not result in a need for a significant amount of new housing,and will not displace existing housing. 10.

The project includes an improvement, extension and dedication of a portion of existing emergency access road to improve public circulation around AGNS and to the existing development of Vista del Mar and residential subdivision in the County. The proposed road connection will implement a preferred circulation alternative (instead of Orchard Ave.) that was originally anticipated when the Vista del Mar subdivision was built. Castillo del Mar will enable access to a potential low density subdivision on the proposed 11.6-acre residential hillside parcel subject to future environmental review. Impact. Due to the grade change on the north shoulder of the existing emergency access portion of Castillo del Mar, additional widening on the north side may require retaining walls. In order to reduce the need for retaining walls to accommodate the 64' right-of-way, the following mitigation shall be required. Additionally, mitigation is required in order to provide for and encourage bicycle transportation, particularly in the vicinity of AGHS. Mitigation/Conclusion. Although no significant traffic-related concerns were identified the following mitigation is required. MM 12.1: No parking or sidewalk shall be provided on the north side of Castillo del Mar where grade change would require substantial retaining walls. Future residential subdivision on the south side of Castillo del Mar will include a curb, gutter, and sidewalk with or without on-street parking. Responsible Party: Developer Monitoring Agency: City of Arroyo Grande—Building & Fire Dept.; Public Works Dept. Timeframe: Prior to issuance of grading permit for future road improvements. MM 12.2: All road improvement plans for Castillo del Mar, including both the proposed improvements and the anticipated future improvements, shall include a minimum of a class II bike lane to provide safe bicycle access in the vicinity of AGHS and the residential subdivisions.

ElU ►� ❑ I) Other ❑ ❑ ❑ Setting. Localized stormwater surface runoff follows the topography of the site northerly toward AGHS and farmland. A season drainage ditch traverses east to west the AGHS sports fields and will run through a proposed pipe under the proposed road extension near Valley Road and continue through existing farmland to Los Berros Creek. Approximately one-acre of irrigated farmland will be removed from production. Impact. Construction and grading activities and exposed soil could cause erosion during project development. An approximate 150 ft. segment of proposed road extension will traverse the vicinity of a drainage ditch, dug seasonally by the agricultural landowner for flood protection. Mitigation/Conclusion. In order to reduce the potential for erosion and to provide for seasonal drainage, the following mitigation is required. MM 14.1: To reduce erosion hazards due to construction activities, grading shall be minimized, and the developer shall provide for a temporary siltation and drainage control basin during construction. All finished slopes shall be hydroseeded with a permanent seed mix composed of native plant species indigenous to the areas. If a drainage structure is widened, • all exposed soil needs to be replanted with native grass plugs or hydroseeded for storm water requirements. Responsible Party: City of Arroyo Grande—Public Works Dept. Monitoring Agency: City of Arroyo Grande—CDD, Public Works Dept. Timeframe: Prior to Grading MM 14.2: Work shall be completed during the dry season (April 15 to October 15) to reduce active construction erosion to the extent feasible.

Surrounding uses are identified on Page 3 of the Initial Study. The proposed project was reviewed for consistency with policy and/or regulatory documents relating to the environment and appropriate land use (e.g., City's Land Use Element, Development Code, Zoning Map, etc.). Referrals were sent to outside agencies to review for policy consistencies and code compliance (e.g. County Agricultural Commissioner, RWQCB, APCD.) As discussed in the section relating to impacts to Agriculture, the proposed zoning and general plan land use designations for the 10-acre AGNS sports fields and 11.6-acre proposed residential hillside parcel are considered internally consistent. The General Plan land use designation and rezoning of the 1.2 acre of farmland requires mitigation. City of Arroyo Grande, initial Study for GPA06-001;DCA06-001; TPM 06-004 Page 18 • The proposal also Includes an area of conservation open space land use designation overlay as shown on the General Plan land use map. This designation is to acknowledge need to'maintain a drainage facility through the AGNS sports fields to prevent flooding and to convey regional drainage to Los Berros Creek and eventually to Arroyo Grande Creek. The proposal does not conflict with this overlay by rezoning from agriculture to ,public facility and the proposed road Improvements and extension will provide for the necessary drainage facility. Mitigation/conclusion. No inconsistencies remain after implementation of all required mitigation and no additional mitigation is determined to be necessary. • • • • City of Arrovo Grande, Initial Study for GPA06-001;DCA06-001; TPM 06-004 Page 19 16.
