b. The water level at the Lopez Reservoir is at or below 10,000 acre feet.
c. There have been six quarterly continuous events of sentry well level readings in the Santa Maria Ground Water Basin below the deep well index trigger level of 7.5 feet, 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.

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.

STAGE 1B RESTRICTIONS
Building restrictions – New water service connections prohibited applied to projects prior to planning entitlement
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.

UWMP REVISIONS
In accordance with correspondence received from DWR, the following key changes were made in initial draft, except the WSCP:
Document format including recent requirements from DWR
Revision of demand management measures, including water conservation
Revision to the projected water demand based on projected build out
Revision to the projected water supply
Revision to the Water Shortage Contingency Plan (WSCP)
27
CWC 10632(a) – Section 7.1 of the UWMP does not provide an outline of the specific water supply conditions that are applicable to each stage of the Water Shortage contingency Plan.
(The changes made to the narrative on pages 7-1 and 7-2 as well as table 7-1 properly address this requirement.)
UWMP REVISIONS
28
2. SB X7-7 Table 2 – This table should indicate that the City used two methods to determine their population, both the Persons-per- Connection method (number 2) and the Department of
Finance (number 1) as described in the UWMP Appendix D, page 5. (This table should be modified in the DWR data base (no further changes needed to the UWMP) to reflect that the
agency used population Method 2 (persons-per- connection) and Method 3 (DWR Population Tool) to determine their historical population. This reflects the description provided in Appendix
D. )
UWMP REVISIONS
29
SB X7-7 Table 7 – This table should indicate that the City used Target Method 1 to determine its 2020 urban water use target, as describe in the UWMP Appendix D, page 8. (This table
should be modified in the DWR data base (no further changes needed to the UWMP) to reflect that the agency selected Target Method 1 to determine their 2020 Target water use, as reflected
in Appendix D, Tables 4 and 6.)
UWMP REVISIONS
30
4. Appendix D Table 7 – the line that reads “2010 Daily per Capita Water Use” should be changed to read “2015 Daily per Capita Water Use”. (This correction was properly made.)
