Emergency Water use restriction
PREVIOUS TRIGGERS
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.
7
MODIFIED TRIGGERS
FOR ADDITIONAL WATER USE RESTRICTIONS
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. (Based on the opinion of the NCMA Hydrogeological consulting firm, GSI, relative to the potential impacts with sustained low
groundwater levels.)
Exit Stage 1B - Lopez Reservoir reaches 15,000 AF or the Council makes a finding that additional water use restrictions are no longer needed.

STAGE 1B RESTRICTIONs
1. Building moratorium and restrictions
2. Prohibition on private vehicle washing

BUILDING RESTRICTION options
Existing planning permit applications deemed complete as of the date of a resolution imposing a building moratorium would be processed and building permits issued for those projects.
New planning permit applications requiring new water meters not otherwise deemed complete by the date of a resolution modifying stage 1 restrictions will be accepted and processed; however,
building permits for those projects would not be issued until stage 1 is declared over.
New commercial/retail use of existing buildings, or redevelopment of existing buildings will be allowed, but only such that water demand will be less than or equal to the existing water
demand.
