Naples Seawall Phase 2

Project Details and Background

The Naples Seawall was carefully evaluated in 2009 and was found to be in a state of significant disrepair. The seawall is public infrastructure and the responsibility of the City of Long Beach. As required by the California Environmental Quality Act (CEQA), in 2010, Long Beach certified a Mitigated Negative Declaration for the project. As such, the City has reserved $9.2 million in Tidelands funding for the project.

The CEQA process was intensive. Long Beach released the Naples Seawall Interim and Long Range Repair Initial Study on January 26, 2010. A Final Mitigated Negative Declaration for the project was certified by the Long Beach Planning Commission on May 6, 2010. A CEQA Notice of Determination was filed with the Los Angeles County Clerk on May 10, 2010.

After significant study of impacts to residents, infrastructure and the environment, the City requested approval from the California Coastal Commission of a waterside project to install a new cantilevered steel sheet pile wall that will not require any tie back anchors, and provide maximum protection to adjacent infrastructure. Four alternatives were evaluated extensively before the request was made. The City's study shows a land-side project is not feasible because it would result in numerous impacts including the removal of all the mature trees and the public walkway along the canals, destabilize house foundations and more than double the cost of a waterside project.

On October 9, 2013, the Coastal Commission voted unanimously to approve the City’s application to proceed with a waterside repair project of the Naples Seawalls. A key component of this action was the approval of a compromise to work with residents through an extensive community input process to design a public walkway on Sorrento Walk that meets the requirements of the Coastal Commission, while addressing neighborhood needs.October 31st, 2015 marked the completion of Phase 1.


The Long Beach City Council awarded a Construction Contract to Reyes Construction, Inc. on June 12, 2019 to perform the Naples Island Permanent Seawall Repair, Phase 2 project. The construction activities include the installation of 2,148 linear feet of new steel sheet-pile seawall on the water sides of the existing vertical seawalls at The Colonnade, the south side and eastern end of Treasure Island, and the western end of the Naples Peninsula. Additional scope includes new sidewalks, guardrails, storm drain systems, lighting, new float access platform supports and modifications, temporary storage/relocation of docks, and replacement of approximately 42 palm trees.

View and Read the Permit


In order to reduce further encroachment of development into the navigable channel, the dimensions of dock floats in Rivo Alto Canal and Naples Canal shall be restricted to a width of six feet (the width is the dimension of the dock float that is measured seawardly from the inland edge of the float to the seaward edge of the float). All dock floats in Rivo Alto Canal and Naples Canal shall confirm to the size limits when they are replaced or substantially repaired, and all docks shall comply with the size limitation no later than December 31, 2028. The City shall include the dock float size limit on all future dock leases and/or permits.


Prior to the placement of any dock floats after the completion of the approved Phase Two seawall repairs, the applicant shall institute a lease program for the project area (all phases), with appropriate prices established in relation to the lease area and temporal length of each lease. The lease program shall allow for the limited-term private use and occupation of state tidelands for development associated with recreational boating activities (i.e., private docks and piers). The money generated by the leases shall be deposited into the City’s Tidelands Fund to be utilized for public access improvements, including the public walkway required by Special Condition Fourteen of this coastal development permit, and future seawall repairs.
