Project Description

The Wilder project included permitting and mitigation for a 1,000-acre residential development in Orinda, California. WRA serves as the  biological consultant and helped developers identify an appropriate parcel adjacent to the development with potential to provide mitigation for impacts to streams, wetlands, Alameda whipsnake, and California red-legged frog. For this 1,000-acre residential project, WRA provided a suite of environmental services including wetland delineations, habitat assessment, species surveys, permit applications, alternatives analysis, EIR review and comment, mitigation planning, and formal endangered species consultation resulting in a non-jeopardy Biological Opinion.

WRA has worked with a number of stakeholders including U.S. Army Corps of Engineers, Regional Water Quality Control Board, California Department of Fish and Game, U.S. Fish and Wildlife Service, City of Orinda, East Bay Municipal Utilities District (EBMUD), East Bay Regional Parks District, Pacific Gas and Electric Company, and numerous interested citizens.

WRA also provided GIS and AutoCAD data organization, analysis, and map production services and production of presentation boards and PowerPoint programs at public hearings and agency meetings.  The WRA landscape architecture department prepared habitat mitigation construction and planting plans for wetlands, streams, and riparian habitats.  WRA led a team of consultants to evaluate and prepare the design for the restoration and rehabilitation to mitigate of over 1600 feet of impacted streams within the project site.wilder brookside creekThis site is part of the EBMUD watershed and provides critical services to water users in the East Bay. At the end of the 10-year monitoring period, the 457- acre mitigation turnkey site will be donated to the EBMUD together with an endowment that will allow for the management of the site in perpetuity. To ensure the success of the project, WRA coordinated with the EBMUD and other local, state, and federal parties to develop a long term management plan compatible with local and regional management and conservation goals.
