How Did a California Dam Get a Section 404 Permit?

Document Type: Proceeding Paper

Part of: North American Water and Environment Congress & Destructive Water

Abstract:

This paper describes the wetland mitigation planning and implementation efforts conducted for the Contra Costa Water Districts (CCWDs) Los Vaqueros Project in eastern Contra Costa County, California. The Los Vaqueros Project involves constructing a dam for a 12,344 hectare-meter (100,000 acre-foot) reservoir, relocating a 21-kilometer (13-mile) portion of Vasco Road and other major utilities around the inundation area, and constructing a new water supply intake on Old River in the Sacramento-San Joaquin River Delta with 32 kilometers (20 miles) of large diameter transmission pipeline. CCWD will also implement a variety of recreational, watershed, and habitat improvements in conjunction with the project. This paper provides an overview of CCWD's process for identifying the least environmentally damaging practicable alternative with emphasis on all aspects of wetland habitat evaluation and mitigation, including mapping, assessing functions and values, selecting mitigation sites, designing and implementing mitigation wetlands.
