Storm Water

Russian River Watershed Association

The City of Cotati is a member of the Russian River Watershed Association, which is an association of cities, the Sonoma County Water Agency, and the County of Sonoma for the betterment of water quality in the Russian River Watershed.

High School Water Awareness Video Contest

The Russian River Watershed Association sponsors a video contest for high school students in honor of Water Awareness Month. The focus topic for the 2012 contest is "Rethink Your Drink - Take it from the TAP!" Cash awards are split between the students who create the winning video and the high school they attend. The winning videos are then used as public service announcements and as educational outreach materials.

Low Impact Development

Low Impact Development (LID), as it relates to storm water, aims to mimic the hydraulic function of the undeveloped site by capturing, treating, and infiltrating storm water as close to the source as possible and using small scale landscape-based features located throughout the project site. Additional Information available.

LID Goals

  • Minimize the adverse impacts from storm water runoff on water quality, the biological integrity of receiving waters, and the beneficial uses of water bodies.
  • Minimize the percentage of impervious surfaces on land development projects and implement mitigation measures to mimic the pre-development water balance through infiltration, evapotranspiration, and capture and reuse of storm water.
  • Minimize pollutant loadings from impervious surfaces such as roof tops, parking lots, and roadways through the use of properly designed, technically appropriate Best Management Practices (BMPs), including source control BMPs or good housekeeping practices, LID planning and design strategies, and treatment control BMPs.
  • Proper selection, design and maintenance of treatment control BMPs, and hydromodification control BMPs to address pollutants generated by land development, minimizing post-development surface flows and velocities, assuring long-term functionality of BMPs, and avoiding the breeding of vectors.
