Paso Robles Groundwater Basin

All new urban and rural development and new irrigated agriculture in the Paso Robles Groundwater Basin (PRGWB) (excluding the Atascadero Sub-basin) are required to offset new water use at a 1:1 ratio. Offset requirements for new urban and rural development is implemented by generating credits through two primary methods: plumbing retrofits and a turf removal incentive (Cash for Grass) program. All new or expanded irrigated agriculture is required to offset new water use at a 1:1 ratio. The Agricultural Offset Program is an implementation tool and is intended to substantially reduce increases in groundwater extraction and lowering of groundwater levels in the PRGWB (excluding the Atascadero Sub-basin) only.

New Development Plumbing Retrofit Verification

The Retrofit-to-Build Program (Title 19) requires all new development that will use water from the Los Osos Groundwater Basin to offset its expected water use at a 2:1 ratio. This offset is achieved by replacing existing plumbing fixtures and water-using appliances used elsewhere in the basin with more efficient fixtures and appliances.

Plumbing Retrofit Program in Paso Robles Groundwater Basin

The County has partnered with the Wallace Group to administer and operate the Plumbing Retrofit Program, which replaces high-flow plumbing fixtures with low-flow plumbing fixtures in homes that are located within the Paso Robles Groundwater Basin area with the goal of reducing daily water use in the area.

Retrofit-on-Sale Plumbing Verification

The Retrofit-on-Sale Program (Title 8) requires all home sellers located in the Los Osos Groundwater Basin area or the Nipomo Mesa Water Conservation Area to verify that all existing plumbing fixtures in the home meet the County's standards for gallons per flush (GPF) and gallons per minute (GPM).
