Frequently Asked Questions
Groundwater management plans are prepared to establish principles for mutual cooperation between participants to guide the sustainable, individual use of the shared groundwater basin. A GMP can:
• Provide tools for water managers to maintain safe and reliable groundwater resources
• Establish baseline groundwater quality conditions for plan area
• Establish a groundwater monitoring program
• Align policy objectives and actions when multiple agencies are involved
• Fulfill requirements for pursuing regional grant funding opportunities
• Enable data sharing among adjacent cities/purveyors and communities
• Incorporate water user, well owner, and other community interests and objectives into water supply management activities
Signed in September 2002, Senate Bill 1938 amended local groundwater management laws to add technical requirements for GMPs and provide guidance on GMP preparation. The amendment stipulated that:
• A GMP contains an inventory of water supplies and describes water uses within a given region.
• A GMP establishes groundwater Basin Management Objectives (BMOs) that are designed to protect and enhance the groundwater basin.
• A GMP identifies monitoring and management programs that ensure the BMOs are being met.
• A GMP outlines a stakeholder involvement and public information plan for the groundwater basin.
All GMPs are broken into four distinct elements: Basin Goal, Basin Management Objectives, Plan Components and Management Actions. Each is a successive yet interrelated step that guides preservation of groundwater resources in the region.
The new WPCGMP is within an area the California Department of Water Resources recognizes as the North American River Groundwater Sub-Basin. The Sub-Basin is roughly bounded by the American River to the south, the Sierra Nevada foothills to the east, the Bear River to the north and the Sacramento River to the west. The WPCGMP area includes the Sub-Basin's eastern edge, Sacramento County to the south, the western edge of Placer County Water Agency's service area, and Bear River to the north. It includes the City of Roseville and portions of the cities of Lincoln and Rocklin.

The Western Placer County Groundwater Management Plan (WPCGMP) is a collaborative effort by local water purveyors to aid in maintaining a high-quality, reliable groundwater supply. The plan is intended to be a "living document" that can be readily updated and refined over time to reflect improved understanding of the groundwater basin as well as progress made in achieving the plan’s goals and objectives.
The over-arching goal of the plan is to maintain groundwater quality and ensure its long-term availability to meet backup, emergency, and peak demands without adversely affecting other groundwater uses within the western Placer County area.
From fall 2008 through the first half of 2009, plan partner staff will conduct workshops and presentations before their boards of directors, local governments, and other organizations such as the City of Roseville Public Utilities Commission. A preliminary schedule available under “Implementation Activities”
will be updated as partners determine the actual presentation dates. To request more information regarding board/council presentations or other implementation activities, please send an email to firstname.lastname@example.org
The partner agencies designated the City of Roseville to lead plan implementation. In order to realize the goals of the WPCGMP, the partner agencies will work together on preparing plan progress reports, facilitating stakeholder involvement, and preparing a monitoring plan for groundwater resource protection. The California Department of Water Resources recently awarded partners an AB 303 Local Groundwater Assistance Act grant, which will also help fund plan implementation. Led by the City of Roseville, partners will use this money to construct three new wells to be used for monitoring groundwater health. A preliminary AB 303 implementation schedule is available HERE
The WPCGMP was a collaborative effort that drew upon previous groundwater management efforts of the plan partners. MWH Americas Inc., a planning and civil engineering firm, assisted in development of the GMP and will assist in plan implementation . Formal WPCGMP partners include:
• City of Roseville - Initial GMP adopted 1998
• Placer County Water Agency - Agency GMP adopted in 1998, updated 2003
• City of Lincoln - Citywide GMP adopted in 2003
• California American Water Company
