Intent To Prepare a Joint Environmental Impact Statement/Environmental Impact Report for the Corte Madera Creek Flood Control Project, Marin County, CA
The U.S. Army Corps of Engineers (Corps) authorized through the Flood Control Act of 1962, Public Law No. 87-4, 87th Congress, 2nd Session, approved October 23, 1962, and amended by Section 204 of Pub. L. No. 89-789, the Flood Control Act of 1966, and the Water Resources Development Act of 1986, will address channel modification opportunities to Unit 4 of Corte Madera Creek, Marin County, CA. The purpose of the Corte Madera Creek Flood Control Project is to provide flood risk management for Corte Madera Creek, from the upstream end of the existing Unit 3 concrete channel to Sir Francis Drake Boulevard at the border of Ross and San Anselmo. Although Units 1, 2, and 3 channel modifications were completed in 1971, public concerns led to a delay in the planned actions for Unit 4. In 1996, Marin County requested the completion of Unit 4 by the Corps, and damages incurred by the December 2005 flood have also renewed public interest in finding solutions to minimize the risk of future floods. Since 1971, additional technical studies were conducted that provide another opportunity to formulate and review new alternatives in order to complete the project. This is a notice of intent to prepare a joint Environmental Impact Statement/ Environmental Impact Report (EIS/EIR) to consider all reasonable alternatives and to evaluate potential impacts associated with the proposed actions. The U.S. Army Corps of Engineers is the lead agency for this project under the National Environmental Policy Act (NEPA) and Marin County Flood Control and Water Conservation District Zone 9 is the lead agency under the California Environmental Quality Act (CEQA).
