Shiloh IV Wind Project


Solano County, CA







Water Resources


EDF Renewables hired WSB to partner with them on the Shiloh IV Wind Project, located in Solano County, California. The project goal was to upgrade existing technology to create more energy, using less equipment, while continuing to protect the environment and surrounding habitats.

WSB was brought on initially to complete the preliminary design of the project, which involved the replacement and installation of 50 turbines (100 MW) within a 3,5000-acre area. The team worked diligently to avoid sensitive species, including the endangered California Tiger Salamander. The team was able to complete the preliminary design while protecting the Salamander’s habitat.

As the project transitioned into the construction phase, WSB continued to work with the contractor to complete final plans, survey turbine sites, and prepare the Stormwater Pollution Prevention Plan (SWPPP) per NPDES and California standards. WSB also served as the Qualified Stormwater Professional (QSP), helping the contractor and owner stay in conformance with California stormwater rules.

The Shiloh IV Wind project was deemed successful, providing an increase of clean energy for the community, while keeping wildlife out of harm’s way.
