Adelaida Area Hydrogeologic Study

The County of San Luis Obispo is coordinating with the U.S. Geological Survey (USGS) to conduct a hydrogeologic study in the Adelaida area west of the City of Paso Robles (click here for map of study area). It is anticipated that this study will provide a better understanding of the hydrogeoglogic conditions in the Adelaida area and provide a factual basis for the development and support of potential future groundwater management actions by the County.

Animal Services Facility

New animal services facility to be constructed at the County Operations Center off Highway 1. The County Board of Supervisors awarded the Design-Build contract for the County’s new animal services facility project to F&H Construction. The new facility will replace the outdated 43-year old public animal shelter that has deteriorated beyond repair.

This project was authorized as a joint effort between the County and Cities of Atascadero, Arroyo Grande, Grover Beach, Morro Bay, Paso Robles, Pismo Beach, and San Luis Obispo. When complete, the new facility will meet the community’s needs by providing an inviting facility for pet adoptions and allow for the humane care of sheltered animals decades into the future.

Cayucos Vets Hall Restoration

This project will stabilize, rehabilitate and restore the Cayucos Veterans Memorial Building (also known as the historic Cass Warehouse) at Cayucos State Beach and create a safe and usable facility for community activities. As a historic building that meets the criteria required for listing in the California Register of Historical Resources,the design for the rehabilitation will follow the Secretary of the Interior Standards for the restoration of historic buildings.

Co-Located Dispatch Facility

The County of San Luis Obispo is in the process of designing and constructing a new Co-Located Dispatch Facility. The Co-Located Dispatch will be located at the County Operations Center off Highway 1.

Paso Basin Aerial Groundwater Mapping Pilot Study

Our community needs a more complete picture of our groundwater resources so that we can make better decisions about managing water into the future. The County of San Luis Obispo was fortunate enough to be among three agencies selected for a pilot study to collect groundwater data in a portion of the Paso Robles Basin (click for map of study area). This pilot study is using innovative technology that could change the way that California collects information about groundwater basins.

What would normally take the County years to survey will only take a few days thanks to new aerial groundwater mapping technology called Aerial Electromagnetic method (AEM).
