About the Western Placer County GMP

Photo of Placer County foothillsThe Western Placer County GMP was developed in accordance with the Groundwater Management Act of 1992 (AB 3030) and a 2002 amendment to the Local Groundwater Management water code (SB 1938).

Work to on the WPCGMP began in 2005 when the city of Roseville and Placer County Water Agency determined that the prior plan provided inadequate guidance for groundwater protection. The City of Lincoln and California American Water Company joined the effort in 2006 to further bolster coordination among the region’s primary stewards of the regional groundwater supply.

The 2007 document improves on its predecessor by expanding the plan’s:

• Integration
• Implementation
• Stakeholder Outreach
• Technical and Policy Detail

The new WPCGMP features four key elements, with the document divided into four sections. The key elements provide a framework for overall management of the groundwater basin. These elements include:

• Goal Statement - States purpose and the desired results
• Basin Management Objectives (BMOs) - Specific, measurable, achievable accomplishments
• Plan Components - Groups of management actions (includes DWR and SB 1938 required, suggested, and voluntary components)
• Management Actions - Specific activities to meet the goal and BMOs

    o Well Construction Policies
    o Well Abandonment and Well Destruction Policies
    o Wellhead Protection
    o Protection of Recharge Areas
    o Control of the Mitigation and Remediation of Contaminated Groundwater
    o Control of Saline Water Intrusion
• Groundwater Sustainability
    o Conjunctive Management Activities
    o Demand Reduction
• Planning Integration
    o Existing Integrated Planning Efforts
    o Potential Future Integrated Planning Efforts 

Section 4 – Plan Implementation

The partner agencies have designated the City of Roseville to lead the implementation of the new WPCGMP. Listed below are the proposed steps and actions for plan implementation, including plan progress reporting, stakeholder involvement, monitoring plan implementation and groundwater resource protection.

Plan Progress Reporting

To ensure continued advancement of WPCGMP goals, plan participants will periodically report on the progress of WPCGMP implementation activities and financing. Reporting activities are outlined below:

• Bi-Annual WPCGMP Implementation Report
• Future Review of WPCGMP
    o Living document
    o Periodic evaluation of actions
    o Determination if actions meet BMOs
• Financing
    o Fee program outlined in Implementation Agreement
    o Cost sharing among Plan Partners
    o AB 303 Local Groundwater Assistance Act Grant funds
    o Provides oversight of WPCGMP across all partners

Stakeholder Involvement
In order to keep basin stakeholders informed of WPCGMP implementation activities, and provide opportunities to engage continued stakeholder opinion and support, the following actions and events are planned:

• Develop a WPCGMP brochure
• Conduct public presentations
• Update WPCGMP website
• Conduct stakeholder coordination and communication
• Conduct County presentations
• Conduct quarterly Technical Review Committee meetings

Monitoring Plan Implementation

The WPCGMP addresses the need to coordinate, conduct, develop and improve a monitoring program capable of assessing the current status of the basin and predicting responses in the basin as a result of future management. Actions which will support these goals are listed below:

• Conduct desktop well inventory assessment
• Provide technical coordination with Department of Water Resources (DWR)
• Update and expand Standard Operation Procedures (SOPs)
• Conduct partner data compilation summary
• Provide, populate, and update data in the Data Management System (DMS)

Stakeholder Involvement in Groundwater Resource Protection

The following groundwater resource protection measures will be implemented to ensure a sustainable groundwater source in the region:

• Develop Well Abandonment Outreach Material and Approach
