County of San Luis Obispo - Interactive Groundwater Basin Mapping Tool

The County of San Luis Obispo Department of Public Works provides an interactive mapping tool to help residents in the County to learn about the local groundwater basins that are managed under the Sustainable Groundwater Management Act (SGMA) requirements.

This interactive mapping tool can help you search and navigate around the groundwater basins by panning, zooming, or using the search box to find a specific parcel or street address. There are different map layers that can be shown and superimposed in this interactive mapping tool such as boundaries for groundwater basins, cities, roads, and agencies. Make sure to check the layer names on the left panel layer menu.

California Department of Water Resources (DWR) - Data and Tools

The California Department of Water Resources (DWR) provides a number of interactive tools and data to help Groundwater Sustainability Agencies (GSAs) develop Groundwater Sustainability Plans (GSPs) and implement the requirements of the Sustainable Groundwater Management Act (SGMA).

Funding Opportunities - Proposition 1 Sustainable Groundwater Planning Grant Program

Sustainable Groundwater Planning (SGWP) Grant Program: Proposition 1, approved by the voters on November 4, 2014, authorized the legislature to appropriate $100-million to the Department of Water Resources (DWR) to establish the SGWP grant program. The SGWP Grant Program is designed to encourage sustainable management of groundwater resources by providing funding for projects that support sustainable groundwater management planning and implementation.

DWR SGWP Grant Program Website

  • San Luis Obispo County Board of Supervisors Resolution No. 2015-302 dated November 17, 2015 authorized the County to file the grant application and execute an agreement for the Sustainable Groundwater Planning "Counties with Stressed Basins" grant program.
  • The County submitted the 2015 County of San Luis Obispo Groundwater Proposal on December 8, 2015 to the California Department of Water Resources for the maximum project funding amount of $250,000.
  • On September 9, 2016, the Proposition 1 - SGWP Grant Agreement No. 4600011507 was executed between the County and DWR.

Basin Boundary Modifications and Prioritization

The California Department of Water Resources (DWR) implemented new basin boundary regulations on November 16, 2015, establishing a process for local agencies to ask DWR to revise the boundaries of existing groundwater basins.

The Final 2018 Basin Boundary Modifications were developed after a technical review of the basin boundary modification requests and public comments. The Final Basin Boundary Modifications were released February 11, 2019 and can be found on the DWR Basin Boundary Modification webpage.

On April 30, 2019, DWR announced Basin Prioritization Phase 2 draft results for basins with modified boundaries. This announcement begins a 30-day public comment period to allow input from the public and local agencies. Public comments submitted to DWR can be viewed by clicking here.

Groundwater Sustainability Agency (GSA) Formation and Groundwater Sustainability Plan (GSP) Development

SGMA established a new structure for managing California’s groundwater resources at a local level by local agencies. SGMA requires the formation of locally-controlled groundwater sustainability agencies (GSAs) in the State’s priority groundwater basins. SGMA also requires that GSAs develop and implement a groundwater sustainability plan (GSP) to meet the sustainability goal of the basin or subbasin to ensure that it is operated within its sustainable yield, without causing undesirable results.

Local Action: On January 13, 2015, the County of San Luis Obispo and Flood Control District Board adopted the SGMA Strategy and subsequently amended on various dates. The overarching strategy seeks to “establish community focused Groundwater Sustainability Agencies (GSA) based on cooperative interagency and stakeholder relationships in order to comply with SGMA requirements.” It also describes specific actions such as seeking the maximum feasible funding through grant applications, supporting establishment of organizational agreements, and maximum feasible outreach to all potentially affected stakeholders.
