Collins Island Bridge Replacement Project

Collins Island Bridge Replacement Project

The proposed project has three major components: 1) bridge replacement, 2) seawall improvements, and 3) future pump station accommodations. The proposed bridge would be designed to be a total of 20 feet and 6 inches in width to accommodate one vehicle travel lane, one sidewalk, and concrete barriers on each side to provide protection from projected sea level rise. The slope profile along the roadway and sidewalk bridge approaches would be adjusted to comply with ADA standards. Street, sidewalk, and landscaping improvements are also proposed on the Balboa Island side along the Bay Front sidewalk and Park Avenue. The proposed seawall improvements would be designed to have an increased top of wall coping elevation to mitigate sea level rise impacts. The City is currently in the process of designing a new storm water pump station on Park Avenue near the Collins Island Bridge as part of a separate project. Therefore, future pump station accommodations are also proposed to accommodate this separate project. Anticipated City discretionary approvals include CEQA clearance and a Coastal Development Permit. The project also requires approvals from additional agencies including, but not limited to, a Coastal Development Permit from the California Coastal Commission, Section 10 and Section 404 Permits from the U.S. Army Corps of Engineers, and Section 401 Permit and Construction General Permit from the Santa Ana Regional Water Quality Control Board.
