The Alder Creek Water Storage and Conservaton Project has been evaluated for water storage and power generation as far back as 1916. Recent extended droughts, downstream fisheries and recent mandates for green energy are additional, present-day considerations supporting renewed interest in the Alder Creek Water Storage & Conservation Project.
El Dorado County Water Agency, in collaboration with El Dorado County and the City of Placerville, is developing a stormwater resource plan (SWRP) for the West Slope of El Dorado County. The SWRP is a watershed-based comprehensive strategic document that summarizes a renewed approach to watershed resource planning and stormwater runoff management in the County. The plan will also incorporate prioritized actions, affordability considerations, and nexus to other related resource planning and implementation efforts to support efficient and responsible implementation. This document is being prepared in accordance with the State Water Resources Control Board's Stormwater Resource Plan Guidelines in order to comply with Water Code sections 10560 et seq. (as amended by Senate Bill 985, Stats. 2014, ch. 555, § 5).
The West Slope SWRP is being developed in close collaboration with the following three agencies. Please click on each agency to be directed to their home webpage.
What is a Stormwater Resource Plan (SWRP)?
A: A Stormwater Resource Plan (SWRP) is a plan that strives to improve and achieve stormwater management objectives. A SWRP is watershed based, non-regulatory, and is driven by stakeholders. A large component of the plan is to identify and prioritize multi-beneficial use projects that can monitor stormwater, capture stormwater, treat and reuse, integrate green infrastructure, augment groundwater, and support low impact development.
What geographic area does the West Slope SWRP cover?
A: El Dorado County is located in Northern California, north east of Sacramento County. The western portion of the county, referred to as the West Slope, is the focus of the West Slope SWRP and covers the portion of El Dorado County west of the Sierra Nevada Continental Divide and excludes the Lake Tahoe watershed (see figure below). The only incorporated city in the West Slope is Placerville, with the remainder of the population living mostly in towns and community service districts.
Why is the West Slope SWRP important?
A: The West Slope SWRP is a comprehensive strategy that will manage stormwater as a resource in the West Slope of El Dorado County. The resulting plan is a multipronged approach customized for its foothill setting which will consider the regional reservoirs, watershed management, and integration of stormwater management. The plan incorporates prioritized actions, affordability considerations, and nexus to other related resource planning and implementation efforts to support efficient and responsible implementation.
How does the West Slope SWRP relate to Proposition 1 funding?
Under Proposition 1, $7.545 billion in general obligation bonds are available for water projects. Such projects may include groundwater and surface water storage projects, ecosystem and watershed protection and restoration projects, and drinking water protection projects. From the Proposition 1 funds available (Water Code Section 79747), $200 million is available in grants to support multi-benefit stormwater management projects.
Under Section 79747 of the Water Code, funds have been made available to fund multi-benefit stormwater management projects. Potential multi-benefit stormwater may include green infrastructure projects, rainwater and stormwater capture projects, in addition to stormwater treatment facilities. To qualify for funding stormwater and dry weather capture project, Stormwater Resource Plans, or functionally equivalent plan(s), are required.

How were projects identified in the West Slope SWRP?
Identified projects were obtained from local agencies, nongovernmental organizations, a state conservancy, and State and Federal agencies.
An e-mail was sent to nearly 20 agencies including local agencies, nongovernmental organizations, state conservancies, and State and Federal agencies, soliciting projects for inclusion in the West Slope SWRP. The multi-benefit projects provided by these agencies are included in the West Slope SWRP.
Who is developing the West Slope SWRP?
El Dorado County Water Agency led development of the West Slope SWRP with close collaboration from the County of El Dorado and the City of Placerville (collectively, SWRP Partners).
How often will the West Slope SWRP be updated?
The SWRP Partners will provide annual updates on project status and plan implementation. Every 5 years the SWRP Partners will assess the need for and prepare an updated SWRP.
Will this be incorporated into an Integrated Regional Water Management Plan?
The projects identified in the West Slope SWRP will be incorporated into CABY (Cosumnes, American, Bear, Yuba) Integrated Regional Water Management Plan.
What is the current status of the West Slope SWRP?
A: The 2017 West Slope SWRP was completed in March 2018. It was adopted by the El Dorado County Water Agency Board of Directors on March 14, 2018.
How can I participate in the West Slope SWRP?

Pine Hill Preserve - Established to protect the rare and endangered plants that grow on the gabbro soils of western El Dorado County. EDCWA is also a Pine Hill Preserve partner.
Upper American River Project
Upper American River Project - The El Dorado Water & Power Authority (”EDWPA”) has reached an agreement with the Sacramento Municipal Utility District (”SMUD”) on water storage in SMUD’s Upper American Project. Now EDWPA is seeking water rights by filing an application with the State Water Resources Control Board.
Hydroelectric Development Options in El Dorado County
Hydro Development on the Western Slope of El Dorado County is being studied to provide power generation on the natural rivers of El Dorado County. Being able to capture Hydro power is an existing source of revenue by way of the natural water flows.
FAZIO EDCWA on behalf of the El Dorado Irrigation District and Georgetown Divide Public Utility District are trying to obtain water transfers from the Central Valley Project. Contracts are negotiated under Public Law 101-514.
