Standing water conditions have been observed along swales and encroaching on the travel lanes of the roadway during minor rainfall events.

Existing Conditions:
GIS data indicates existing swales and catch basins along the east and west sides of the road, with a trunk line on the east side. The southernmost pipe from the southernmost catch basin continues southward towards Lake Worth Road, connecting to a mislabeled manhole on the north side of Lake Worth Road, with a drainage pipe observed leading eastward from the manhole. This outfall pipe is presumed to connect to FDOT drainage features along Lake Worth Road.
LiDAR data shows high points in the road centerline at the north and south ends of Edwards Avenue which provide containment for runoff, provided swales are graded accordingly and maintained free of growth and debris. Road elevations along Edwards Avenue are slightly lower than adjacent residential properties.
Recommended Improvements:
All components of the existing drainage system should be cleaned and videoed for further assessment. Based on available data, maintenance of swale flow lines to remove growth or obstructions is recommended as an initial activity. Replacement of the mislabeled manhole cover at Lake Worth Road should be included.
Regulatory Approvals:
Pending the results of survey and video investigations, discharge will be through existing components. Additional regulatory approval should not be necessary to implement the recommended improvements.
Project Cost:
The estimated cost of this project is $140,000. A detailed Opinion of Probable Construction Cost and Schematic Design drawing, and Drainage Area exhibit are attached
