The Canal Maintenance Division is responsible for the maintenance of seawalls and dredging of canals located within the Burnt Store Isles and Punta Gorda Isles canal districts. Other duties include depression filling, seawall patching, cap patching, cap replacement, maintenance of aids to navigation, inspections, and related tasks.
Seawall replacement, channel and inlet dredging, seawall stabilization, and mangrove trimming projects are accomplished by outside contractors selected through the competitive bid process.
The Canal Maintenance Division also performs an annual assessment of the seawall systems. This assessment records condition data of the seawall and it is mapped in a GIS (Geographical Information System) system. GIS mapping allows the Division to prioritize maintenance and replacement tasks. The data will allow the Division to continue the forecasting of estimated seawall longevity.
Seawall Replacement Work Program
Approximately 8,000 linear feet of seawalls are replaced every year. By utilizing the Annual Seawall Assessment data, the Seawall Replacement Work Program is planned is planned a year in advance (seawalls that fall into the canal unexpectedly or a seawall that is inspected and found to be at extreme risk of failure is given a priority).
