Project

Dry Creek Levee Relocation
City of Roseville, California

West Yost provided planning, analysis, environmental review, permitting, design, and construction management services for the Dry Creek WWTP Levee Relocation. This project included the hydrologic and hydraulic analyses of Dry Creek in the vicinity of the WWTP. The project provides 100 year protection of the wastewater storage ponds while enhancing the flow carrying capacity of Dry Creek in an environmentally sensitive manner.

In addition to planning, design, and construction phase services for the Dry Creek Levee Project, West Yost managed the CEQA review, public participation, and permitting elements of this project. Permitting efforts included working with the Regional Water Quality Control Board (NPDES Construction permit), Central Valley Flood Protection Board (Encroachment Permit), and the California Department of Fish and Game (Stream Bed Alteration Agreement).

The project was intentionally designed to avoid any construction in the delineated waters/wetlands of the United States, thereby avoiding the need for a Clean Water Act Section 401 State Water Resources Control Board Certification and a Clean Water Act Section 404 US Army Corps of Engineers permit.
