Drought 2014

On January 17, 2014 Gov. Brown declared a drought state of emergency; directed state officials to take all necessary actions in response. 

Calendar year 2013 closed as the driest year in recorded history for many areas of California, and current conditions suggest no change in sight for 2014. Much of unincorporated Napa County relies on groundwater or local supplies. Please visit the Save Our Water website to find information and tips on how to conserve water. 

Make sure your outdoor irrigation is turned off. Make irrigation scheduling easy, and visit the City of Napa's water conservation page to find out more.

Rainwater Harvesting Incentives

The Napa County Flood Control and Water Conservation District offerings rebates to residents of the Napa River watershed who install rain gardens and rain barrels/cisterns on their property.

Roofs and other impervious surfaces alter natural hydrology, increasing the volume and velocity of stormwater runoff. This has a variety of impacts including

  • streambank erosion
  • degraded wildlife habitat
  • potholes
  • structure damage
  • beach closures, and
  • in severe cases, land and mud slides.

Fortunately there are simple low-cost things that we can do to decrease the volume of, and minimize pollutants in, the runoff from our properties.

Rain gardens and rain barrels/cisterns are two simple strategies designed to slow, spread and sink stormwater before it has a chance to impact local creeks. 
Rain gardens are landscaped areas designed to capture and treat rainwater that runs off roofs and paved surfaces. The Flood District will reimburse applicants in the Napa River Watershed $5 per square foot installed, up to a maximum of $1,500 for residential properties and up to $5,000 for Commercial, Industrial and Institutional properties.

Rain barrels and cisterns can be installed to capture stormwater runoff from rooftops and store it for later use. Residential property owners in the Napa River watershed may receive a 75% rebate for approved expenses up to $2 per gallon of storage capacity and $500 maximum per household. Commercial, Industrial and Institutional applicants may receive a 75% rebate for approved expenses up to $2 per gallon and $1,000 maximum.

Funding for this program comes from the State of California water bond measure, Proposition 84, administered by the California Department of Water Resources, and is subject to funding availability.

In September 2009, the Napa County Board of Supervisors authorized County staff to begin outreach on a water conservation program in the unincorporated county, specifically targeting the Milliken-Sarco-Tulocay (MST) area. County staff, with input from the agricultural community, the Napa County Resource Conservation District, and the California Department of Fish and Game have come up with some opportunities to help residents, growers, and winery owners alike conserve water.
