WATER SUPPLY CONDITIONS
PREVIOUS TRIGGER Level Considerations
Declaration Of A Stage 2 Water Supply Condition Per The City’s Existing Ordinance (This could occur based upon a threat to a local water supply, water delivery system, state mandated
reductions, or a combination);
Reduction of Lopez Supply of 35%; or
The SMGWB continually falls below the Deep Well Index Trigger Level of 7.5 feet in conjunction with Lopez supply reduction of 20% or indications of sea water intrusion are detected.

RECOMMENDED
WATER SUPPLY CONDITION TRIGGERS
STAGE IB
Interruption to local water deliveries, water delivery system or State mandated reductions.
Lopez Reservoir level at or below 10,000 AF.
Six quarterly continuous monitoring events of Sentry well water level readings in the SMGWB below the deep well index trigger level of 7.5 feet in conjunction with Lopez supply reduction
of 20 % or indications of sea water intrusion are detected.
Exit Stage 1B - Lopez Reservoir reaches 15,000 AF and increasing or the Council makes a finding that additional water use restrictions are no longer needed.

STAGE 1B RESTRICTIONs
1. Building restrictions – New water service connections prohibited applied to projects prior to building permit issuance
2. Prohibition on private vehicle washing
Further reduce overall irrigation of City-owned non-sports field turf areas to 25% of the 2015 use
Increase the mandatory water use reductions for residential water customers by 5% for each of the three water rate tiers

WATER OFFSETS
Water Neutralization Fee: Existing fee intended to provide an 1:1 offset over time as water conservation retrofits are completed.
Demonstrated to AN effective TOOL to reduce our per capita demand : As city has grown overall water demand has remained stable.
More robust offset during stage IB: A 1:1.5 would help ensure adequate savings are achieved during sever water shortage conditions.
Menu of opportunities: Additional 0.5 accomplished through immediate retrofits or water purchase and verified in advance of approval.

BUILDING RESTRICTION considerations
Vesting Maps and Development Agreements
Continuing to process projects during Stage IB
Small infill project (e.g. 4 or less lots) can be exempted or can achieve 1:1.5 through fees
Projects with existing water service connections can continue under building restrictions

Building restrictions
PROJECTED WATER SAVINGS: Development projects currently in the entitlement process would account for an increase of approximately 35 AF/year or less than 2% of the anticipated 2,300
AF citywide annual water demand.

2015 Uwmp process
Adopted by city council on June 28, 2016
State Department of water resources (dwr) advances review of city’S UWMP
Dwr requires modifications to the water shortage contingency plan (wscp)
Wscp currently contains two drought response stages
Dwr requires more detailed stages of drought response in wscp
Council approved Triggers and demand reductions crafted to meet dwr requirements
Three stages with corresponding demand reduction measure recommended
Revised uwmp to be considered by city council on january 24, 2017

ADDITIONAL STAGE 1 RESTRICTION RECOMMENDATIONS
Prohibition on private vehicle washing
PROJECTED WATER SAVINGS: Unknown. Less than 1AF per year.
22
ADDITIONAL STAGE 1 RESTRICTION RECOMMENDATIONS
Further reduce overall irrigation of City-owned non- sports field turf areas to 25% of the 2015 use
PROJECTED WATER SAVINGS: 7.5 afy
23
ADDITIONAL STAGE 1 RESTRICTION RECOMMENDATIONS
Increase the mandatory water use reductions for residential water customers by 5% for each of the three water rate tiers
PROJECTED WATER SAVINGS:
Annual Demand- 2,200 AFY X 80%= 1,760 afy
Residential use- 1,760 Afy X .5%= 88 afy
