Document Description
The 0.61-acre project site is located in the city of Thousand Oaks, on the west side of Hill Canyon Road, approximately 1.75 miles south of the intersection of Santa Rosa Road and Hill Canyon Road, and approximately 330 feet northwest of the treatment ponds at the Hill Canyon Treatment Plant. The project site is located on approximately 0.61 acre of a larger 495-acre parcel identified as Assessor’s Parcel Number 667-0-120-160. The new bridge will span over Arroyo Conejo Creek in Hill Canyon. The Conejo Open Space Conservation Agency (COSCA), a joint powers authority consisting of the City of Thousand Oaks (City) and the Conejo Recreation and Park District, and the City’s Public Works Department are proposing the project, composed of a new bridge which would span Arroyo Conejo Creek in Hill Canyon, and an associated access road to connect the eastern side of the new bridge to the existing Hill Canyon Road. The western end of the proposed bridge would be positioned to tie into the existing Hill Canyon fire road which descends into the canyon from the north end of Rancho Conejo Drive. The east end of the proposed bridge would connect to Hill Canyon Road through construction of a short, new access road. The purpose of the new bridge is to improve access to existing open space areas for outdoor recreationists as well as City and COSCA staff vehicles.
