Peterson Ranch Advanced Storm Water Treatment System

Peterson Ranch in Suisun, CA is a housing development recently built out by K Hovnanian Homes. The site discharges to a wetland to the south that eventually runs into Suisun Bay. Fairfield Suisun has stricter guidelines due to the Suisun Bay water quality concerns.

The site is relatively flat but the soils are very fine colloidal clays. Thunder Mountain designed this advanced treatment system to protect the wetland that flows to Suisun Bay during wet season construction, resulting in a clean outflow less than 10 NTU.
