Hetfield Estates Subdivision

The California Department of Fish and Wildlife has executed Lake and Streambed Alteration Agreement EPIMS-CCA-59564-R3, pursuant to Fish and Game Code section 1602, for the Hetfield Estates Residential Subdivision project. The agreement, approved on August 27, 2025, authorizes project applicant Sridhar Pillarisetty to install an arched culvert bridge and two armored stormwater outfalls at Larch Creek in Moraga, Contra Costa County. The bridge construction involves steel piers within concrete foundations located below the top-of-bank, while the outfalls will be secured with planted rock slope protection. Project activities include vegetation clearing, ground disturbance, and the installation of hardscape and bridge components. These activities will result in the removal of thirteen native riparian trees and cause temporary impacts to 3,006 square feet and permanent impacts to 1,133 square feet of riparian habitat. To mitigate these effects, the project requires the revegetation of temporarily disturbed areas and the installation of native plantings, adhering to a Mitigation Reporting or Monitoring Plan adopted by the California Department of Fish and Wildlife. The Town of Moraga serves as the lead agency for the development.
