The Ranch on Silver Creek

Restoration and Monitoring Plan and Regulatory Compliance Monitoring for a 450-Acre Site in San Jose.


  • Assist developers with design and implementation of Silver Creek Preserve restoration and monitoring plan
  • Ensure environmental regulatory compliance through annual biological monitoring


Project Description

In support of a 450-acre housing and golf course development, WRA assisted William Lyon Homes, Inc., with a major habitat restoration effort leading to the creation of the Silver Creek Preserve.  WRA’s biologists and landscape architects worked with the developer to create a comprehensive Restoration and Monitoring Plan as required by the U.S. Fish & Wildlife Service (USFWS) and the U.S. Army Corps of Engineers (Corps).  The plan included restoration of habitat for special-status plant and wildlife species including federal-threatened bay checkerspot butterfly, California red-legged frog, and California tiger salamander and federal-endangered Santa Clara Valley dudleya and Metcalf Canyon jewelflower, among other sensitive species.  The restoration plan included the design of mitigation wetlands as well as riparian and native grassland plantings to comply with the Corps, USFWS, Regional Water Quality Control Board, and California Department of Fish and Game permits issued for the project.


WRA is currently implementing a 10-year biological monitoring program for the restoration effort, including rare plant and bay checkerspot butterfly annual surveys at an off-site mitigation parcel near Kirby Canyon in the Coyote Valley.
