Sonoma Mountain Village

Biological Surveys and Permitting for a Proposed Sustainable Development in Sonoma County.


  • Provide biological assistance for development of a “One Planet Community” incorporating sustainable development ideals
  • Determine biological opportunities and constraints and avoid and minimize impacts to biological resources


Project Description

Sonoma Mountain Village is a proposed sustainable work and live development on approximately 200 acres in Rohnert Park, California.  The project is located partially on the former Hewlett Packard-Agilent Research Campus and partially on vacant land within the Santa Rosa Plain geographic area.  The development aims to create a sustainable community with 100% of the energy needs coming from on-site renewable energy sources.

WRA assisted developers with biological surveys and environmental permitting during the initial phases of project development.  WRA conducted studies to identify and map areas of potential jurisdictional wetlands and accompanied the U.S. Army Corps of Engineers during a site review to approve the delineation.

WRA also conducted a habitat assessment for endangered plant and wildlife species, including the federally threatened California tiger salamander.  The biological information gained from these studies and surveys was utilized in the draft Environmental Impact Report (EIR) prepared for the project in 2009. The project was approved by Rohnert Park Planning Commission and City Council in 2010.
