VAFB-2018-17: Mitigation and Monitoring Plan for the San Antonio Road West Bridge Maintenance at Vandenberg Air Force Base, CA

Summary

This Mitigation and Monitoring Plan (CMMP) provides the concepts and direction for implementation and maintenance of the mitigation required to compensate for impacts to California State Waters associated with repairs to the San Antonio Road West Bridge. The site is dominated by riparian vegetation within the channel, throughout the bridge gabions, and on the creek banks. Due to the nature of the proposed action, the requirement for riparian vegetation removal, and subsequent maintenance to keep vegetation cleared under the bridge, willow forest restoration will take place off site. Onsite restoration will occur in areas of the proposed action area that incur temporary disturbance, caused from access, exclusionary fencing installation, and other temporary impacts not related to vegetation removal under the bridge itself. The off‐site mitigation area is located adjacent to San Antonio Creek downstream of the proposed action area. This CMMP is required by the Central Coast Regional Water Quality Control Board (RWQCB) water quality certification pursuant to Section 401 of the Clean Water Act (CWA). This mitigation plan describes the site preparation, installation methods, and maintenance required until the performance standards are met.
