Title

Cabrillo Bridge Replacement Project

Description

The Applicant intends to replace a deteriorated existing bridge, with a 131 foot long, 90 foot wide bridge, with six foot wide side walks on each side. Also, a trail bridge for pedestrians and bicycle riders will be constructed on the south side of the new bridge. It will be 20 feet wide, and carry several utility lines, including an 8 inch gas main. A temporary pedestrian and bike bridge will be constructed about 50 feet south of the existing bridge to maintain public access during construction. The 14 foot wide, 100 foot long bridge will span the lagoon and will carry the utilities until the permanent bridge is completed. The temporary bridge and abutments will be removed after completion of the project. New bank protection will be installed on the on both banks between Cabrillo and State Street to replace existing timber pile walls. Vertical pre-cast concrete walls will match the alignment of the existing walls, but will be set back near the bridge, to transition to the wider configuration. A planting zone with the average width of 15 feet will be installed on the north bank, and an average of a 2 foot wide zone on the south bank. This area will be planted with native species. Ungrouted boulders will replace the existing sackcrete bank protection and will be installed on both banks downstream of the trail bridge, 90 feet on the west side and 160 feet on the east bank. The walls include tidewater goby hideouts or 'refugia', and boulder clusters for both steelhead and tidewater gobies to hide in during strong flows. Native plants will be planted in a 10 foot wide strip above the boulders.
