Naples Island Permanent Seawall Repair, Phase 2
Location: Long Beach, CA
Owner: City of Long Beach
Description: Replacing of the existing concrete seawall, which consists of:
- Pre-cast concrete sheet piles
- Steel tie-back anchors
- Cast-in-place pile cap.
Was originally built in the late 1930’s and 1960’s due to damages, which includes:
- Sulfate deterioration and spalling of concrete
- Corrosion of the tie-back anchors
- Loss of soil through open joints (necessitating grouting behind the wall)
- Differential subsidence
- Sinkholes in the ground supported by the seawall
The work consisted of the installation of approximately 2,148 lineal feet of a new steel sheet-pile seawall on the water side of the existing vertical concrete seawalls along the canals of Naples Island via the hydraulic press-in method.
Work also included:
- Construction of a new reinforced concrete pile cap
- Removal and installation of existing docks
- Removal and disposal of existing guide piles and mooring pipes
- Driving new concrete guide piles
- Guardrails
- Sidewalks
- An improved drainage system
- Modified access platforms
- Pipe moorings and ladders
- Relocation of existing street lighting along the canal
