Huntington Harbour Bulkhead Repair Mitigated Negative Declaration
Summary: Tetra Tech, Inc. is currently working with 30 homeowners in Huntington Harbour to repair bulkheads. The proposed project area includes homes on Davenport Island, Trinidad Island, Gilbert Island, Humboldt Island, Edgewater Lane and Morning Star Drive. The purpose of the project is to restore the foundation of the bulkhead and provide toe protection to inhibit any future scouring or erosion, which may jeopardize the bulkhead’s structural integrity. The bulkheads in Huntington Harbour are made of reinforced cast-in-place concrete and untreated timber piles supporting the footings. Due to the time span of design and construction, there are slight differences in bulkhead design among the properties. Some sections of the bulkhead have a cutoff wall below the bulkhead and some do not have a cutoff wall. Over the years, erosion due to localized tidal currents, recreational boat use and periodic maintenance dredging activities in the area have undermined the bulkhead, damaged the support piles and threatened the overall structural integrity. Properties located on the main channel show the greatest erosion levels.
The repair project would consist of three phases: pile repair, placement of sheet piles and installation of slope protection, although not all phases would apply to all properties. All three phases will be staggered and performed concurrently at certain stages to minimize total project duration. The total duration of the project is estimated to take 120 working days.
The draft Mitigated Negative Declaration will be available for public review and comment for 30 days, commencing Thursday, July 31, 2008 and ending Friday, August 29, 2008. Written comments on the draft MND must be submitted to Jennifer Villasenor, Associate Planner, City of Huntington Beach Planning Department, 2000 Main Street, Huntington Beach, California 92648 by 5:00 p.m., Friday, August 29, 2008.
