Flood Control and Water Resources
The Napa County Flood Control and Water Resources Division is responsible for County-wide flood control activities, assisting with the management of the County’s unincorporated area water supplies and imported water supplies from the state Water Project and providing operations and maintenance services for two small water and sewer district at Lake Berryessa. As such, our group takes on water and flood control related planning, management and construction activities.
The Napa County Flood Control and Water Conservation District’s mission is the conservation and management of flood and storm waters to protect life and property; the maintenance of the County watershed using the highest level of environmentally sound practices; and to provide coordinated planning for water supply needs of the community. We invite you to visit the Flood Control and Water Conservation District Web site.
Natural Resources Conservation
As a part of the County's reorganization efforts, a new Natural Resources Conservation group was formed in Public Works to consolidate related programs and functions. The following programs are a part of this new group:
In September 2009, the Napa County Board of Supervisors authorized County staff to begin outreach on a water conservation program in the unincorporated parts of Napa County. We invite you to visit the Napa County Water Conservation Web site.
Milliken-Sarco-Tulocay (MST) Water Project
The Milliken-Sarco-Tulocay (MST) area is located in an unincorporated area of Napa County, due east of the City of Napa. In 2003, the United States Geological Society, in cooperation with Napa County, completed a study of the groundwater resources in the MST area. Data showed that groundwater levels have declined significantly since a previous study of the area was completed in 1977, and the review concluded that an increase in groundwater extraction since the 1950's has resulted in the general decline of groundwater levels throughout the area. Napa County continues to work with other agencies to address the water supply issues in the MST area. For information on projects in the MST area, please visit the MST Web site.
For information on watershed projects throughout Napa County, please visit the Watershed Information Center and Conservancy (WICC) Web site. The WICC is a watershed resource management program that provides public outreach and coordination, inventory and assessment, and watershed data management. The goal of the WICC Web site is to collect, organize, and make available to the public, environmental data and information to support community efforts to understand and better manage the county’s watersheds.
Groundwater Programs and the Groundwater Resources Advisory Committee
Napa County has been monitoring the county's groundwater resources since the mid 1900's. Napa County continues to work on efforts to: expand voluntary groundwater monitoring in key locations; develop better data collection procedures; estimate rates of aquifer recharge; study groundwater and surface water interactions; and report on annual conditions and trends. In 2011 the Board of Supervisors appointed 15 residents to the Groundwater Resources Advisory Committee (GRAC). The members represent diverse interests including, environmental, agricultural, development, and community interests. The GRAC was created to assist County staff and technical consultants with recommendations regarding groundwater resources and sustainability, including development of a voluntary Groundwater Monitoring Plan. Committee meetings are held bi-monthly on the fourth Thursday of the month at 2:00pm at the Napa County Agriculture Commissioner's Office/UC Cooperative Extension, 1710 Soscol Avenue, Suite 3, Napa CA. For more information on the Groundwater Programs and the GRAC, visit the GRAC website.
Recycling and Waste Information
The Recycling and Waste Reduction Team implements programs to reduce the volume and toxicity of “waste” destined for landfills in order to conserve valuable natural resources and protect public health. We assist residents, businesses and institutions with activities that reduce and prevent waste, maximize recycling, compost organic materials, and minimize use and disposal of toxic products.
