Title

New High School at College and Cannon

Description

The Applicant proposes to alter portions of two unnamed drainages into Calavera Creek to accommodate the New High School and Cannon Project. The project supports 0.22 acres of waters of the State. Construction of the project would result in permanent impacts to freshwater marsh (0.07 acres), mule fat scrub (0.10 acres), and ephemeral streambed (0.02 acres). The project will avoid 0.03 acre of the 0.05 acre of streambed occurring on site. Minimization of project effects on jurisdictional areas will be through the on-site relocation of the existing drainage, rather than placing it underground. The relocated channel will remain as a natural bottom channel, thereby retaining some functions and values of the system, including groundwater recharge, flood attenuation, and pollutant uptake. East/west and north/south oriented bioswales will direct storm flows into Calavera Creek. To ensure minimal effects to downstream waters, Best Management Practices (BMPs) would be implemented during construction of the project, in accordance with the site's Storm Water Pollution Prevention Plan (SWPPP). In addition to the above, the site plan has been revised to provide a minimum 110-foot buffer between the project and Calavera Creek. Mitigation for impacts shall be accomplished through the creation, restoration/enhancement and/or preservation of like habitat within Department approved offsite and onsite mitigation areas dedicated as open space.
