Standing water conditions have been observed across the roadway just south of Lakewood
Road during minor rainfall events.
GIS data shows minimal storm water management in this area. Swales are shown along the east and west sides of the roadway between Lake Worth Road and Canal Road.
In the southernmost portion of Coconut Road, high points at intersections with Lake Worth Road and Lakewood Road define the limits of the drainage boundary. A low point about midway between the two cross streets is in line with structures from Serubi Avenue, Corrigan Court, and Gulfstream Road. These structures lie within an existing 10’ wide platted drainage easement which continues to the west side of Davis Road. 12” PVC culverts beneath Coconut Road and Gulfstream Road connect a ditch within the easement to the main outfall located on Gulfstream Road. This outfall connects to the FDOT-operated drainage system serving Lake Worth Road and ultimately discharges to the LWDD L-12 Canal.
The northern portion of Coconut Road is located between Lakewood Road at the south end and Canal Road at the north end. High points at intersections with these roads define the limits of the drainage boundary. A low point is located just north of the west end of Hunt Road. This portion of Coconut Road does not currently include a drainage system, but a structure and outfall pipe were installed at Canal Road as part of improvements being undertaken along that roadway. The existing outfall pipe discharges to the LWDD L-11 Canal.
Based on a review of plat documents, an existing 10’ wide drainage easement runs east-west between Davis Road and Coconut Road, located approximately 475 ft. south of Hunt Road and in line with the north end of Pleasant Place. This easement makes a ninety degree turn to the north at Coconut Road and proceeds north along the west side of the roadway to L-11 Canal.
No existing permits were located in the area.
The schematic design for Coconut Road includes the installation of new structures to collect standing water from a low point along the southern portion of the roadway. The proposed structures will be piped to the existing drainage easement for conveyance to a point of outfall. The existing culvert underneath Coconut Road does not include a structure, therefore installation of one is proposed for connection of the proposed pipe. Restoration of swales along the roadway is recommended for conveyance to the catch basins. Clearing and restoration of the existing easement is also recommended as an improvement to the overall system managing drainage between Lake Worth Road and Lakewood Road.
In the norther portion of the roadway, additional catch basins are shown in low and narrow points to collect runoff. A proposed trunk line along the west side of the road will connect to the existing catch basin and outfall, which discharge to the LWDD L-11 Canal.
The proposed system will discharge to either the FDOT-managed Lake Worth Road drainage system or the LWDD Canal L-11 through previously installed outfall components. Additional regulatory approval may be required from LWDD for connection of the proposed catch basins and culverts, or from FDOT for storm water routed through the Lake Worth Road drainage system.
The estimated cost of proposed improvements is $170,000 for improvements from Lake Worth Road to Lakewood Road. Improvements from Lakewood Road to Canal Road are estimated to cost approximately $195,000. All improvements along the full length of Coconut Road total approximately $365,000.
