The applicant seeks a coastal development permit and grading permit for bridge repairs done in September 2015 and replacement of the bridge with a new 20-ft. wide free spanning bridge over Butano Creek on Giannini Ranch, owned by POST. The existing wood bridge will be demolished. The bridge site provides the only access to the agricultural fields on the west side of the segment of Butano Creek. Replacement of the bridge will restore brigde loading capacity necessary for agricultural operations. Construction of the new bridge includes new bridge supports (i.e. concrete abutments and wingwalls) to be constructed outward of top-of-bank and above the ordinary high and wingwalls) to be constructed outward of top-of-bank and above the ordinary high water line in order to minimize impacts to the creek. The project includes widening of the gravel roadway approaches to the bridge to conform to the new bridge width as well as the installation of a rock inlet at the existing storm drain, installation of swales, and placement of Class II aggregate base. A grading permit is required for 150 cy of cut and 400 cy of fill. No work is proposed to occur within Butano Creek and creek dewatering is not required to implement the project.
