Project Design:

• SAI designed and prepared construction plans for a number of drainage retrofit features including pond excavations, gabion construction, roadway reconstruction, box culvert and outfall structure design, sanitary sewer relocation, and littoral zones, and an in-line floatable debris skimmer and trash trap.

• Public involvement was incorporated into the design process.

• Another design feature bifurcated the main channel to improve water quality in the previously stagnant Laguna Pond.

• SAI was also responsible for permitting of the project through FDEP as well as submittal of flood plain revisions to FEMA.

 

Stormwater Modeling / Investigation:

• Modeling of the 3 square mile watershed was conducted using the FEMA approved ICPR model.

• A comprehensive inventory and evaluation of the existing drainage system was conducted.

• Flooding areas were identified and/or confirmed through a detailed comparison of modeled flood stages with known roadway and structure elevations.

• It was determined that flooding was due in large part to lost storage capacity from siltation in existing ponds.

• A master drainage plan was prepared to summarize the existing conditions analyses and present a plan to rectify the deficiencies.
