AI Contract Overview

The Canyon Rock Restoration Project, identified by Lake and Streambed Alteration Agreement EPIMS Notification No. EPIMS-SON-59933-R3, is a regulatory agreement executed by the California Department of Fish and Wildlife with Jon Trappe. The project is located at an unnamed tributary to Green Valley Creek in Sonoma County, California, specifically at 7525 Highway 116, Forestville. The primary objective is to restore riparian and wetland habitats adjacent to the active Canyon Rock Quarry to offset unauthorized habitat removals caused by previous quarry expansion activities. These unauthorized activities resulted in the loss of 0.09 acres of riparian habitat and 0.31 acres of wetland habitat, leading to notices of violation from the County of Sonoma and the North Coast Regional Water Quality Control Board. The restoration scope involves significant physical modifications to the landscape, including moving an existing berm to reconnect the tributary headwater, grading a quarry detention pond to create wetland benches and a seasonal pond, recreating a seasonal stream channel, and disconnecting an existing culvert. Additionally, the project requires the construction of rock-lined energy dissipators and a two-phase revegetation process. Upon completion, the project will restore 0.39 acres of riparian habitat and 0.62 acres of wetland habitat, resulting in a net increase of approximately 0.30 acres of riparian habitat and 0.31 acres of wetland habitat compared to pre-impact levels. The project is exempt under California Code of Regulations, title 14, section 15333, as it is under five acres and serves to protect wildlife habitat. All access and staging will be confined to existing roads and developed areas within the quarry footprint, with no additional temporary or permanent habitat impacts expected.

Full Description

The California Department of Fish and Wildlife has executed Lake and Streambed Alteration Agreement EPIMS Notification No. EPIMS-SON-59933-R3, pursuant to Section 1602 of the Fish and Game Code to Jon Trappe. The project is limited to restoration of riparian and wetland habitat adjacent to the active Canyon Rock Quarry to offset impacts to open stream channel habitat, riparian habitat, and seasonal wetland habitat, which were removed without authorization from CDFW as part of quarry expansion activities. The County of Sonoma and North Coast Regional Water Quality Control Board also did not authorize the habitat removal activities and issued notices of violation to the Permittee. The restoration work consists of moving an existing berm to reconnect the headwater of the unnamed tributary to the restored wetland and stream channel, grading within a quarry detention pond to recreate wetland benches and form a seasonal wetland pond, recreation of a seasonal stream channel, disconnection of an existing culvert currently directing flow from the unnamed tributary into the quarry settling pond, construction of associated rock lined energy dissipators, and a two-phase revegetation of the newly restored riparian and wetland habitat. The unauthorized work within the quarry resulted in permanent impacts to the original stream channel, which included impacts to the following features: 0.09 acres (562 linear feet) of riparian habitat and 0.31 acres (293 linear feet) of wetland habitat. The project will restore on-site the stream channel that previously existed at the site, including restoring the following features: 0.39 acres (1,024 linear feet) of riparian habitat and 0.62 acres (298 linear feet) of wetland habitat. This restoration will result in an increase of approximately 0.30 acres (462 linear ft) of riparian habitat and an increase of approximately 0.31 acres (5 linear feet) of wetland habitat compared to what existed prior to the unauthorized impacts. Access and staging will occur within existing roads and developed areas within the quarry footprint. No water will be present within the work area during construction. The project will not result in any additional temporary or permanent impacts to riparian habitat or wetland habitat as the habitat was already removed as part of the unauthorized work described above.
