SUBJECT: MIAMI BEACH SEAWALL PRO ECTS STATUS
The purpose of this Letter to Commission is to provide an update regarding the various seawalls that
have been slated for reconstruction as part of the City's initiative to mitigate against sea level rise by
upgrading vulnerable infrastructure.
To date, almost one mile of city-owned seawalls has been reconstructed. An additional six (6) segments
have been identified and planned for re-construction, as the low-lying elevation and poor condition of
those segments impact the properties at those locations. The six additional segments are located along:
Jefferson Ave, Lenox Court by the Collins Canal, Garden Avenue, Bonita Drive, the North End of Rue
Notre Dame, and the North End of Trouville Esplanade.
In 2011, a comprehensive seawall assessment was performed by Coastal Systems International. During
this assessment, all seawalls that were not part of a neighborhood construction or improvement project
were re-evaluated andassessed by condition, including their likelihood to fail and critical need of
maintenance. In 2015, using the 2011 seawall assessment as a basis, the City of Miami Beach's Public
Works Department performed a visual structural inspection and elevation assessment on the city-owned
seawall segments and generated a prioritization list for seawall reconstruction to be implemented as
funds became available. In 2016 the City Commission approved the recommendation of the Mayor's Blue
Ribbon Panel on Flooding to increase the seawall top-of-cap minimum elevation from 3.2 feet NAVD to
5.7 feet NAVD for all new private and public seawall projects.
Supplemental funding was made available by the community's backing of the 2018 General Obligation
Bonds, which will continue to support investments in city-owned seawalls. The Public Works Department
is actively working on the next six seawall segments with more to come. The design, permitting, and
procurement processes will take approximately 6 to 12 months, with an additional 3 to 6 months allocated
toward coordination and construction activities.
