219: Stormwater Pond Relocation Project

S&H Investments Group, a real estate developer located in Clay County, Florida, owns a large piece of land on US Highway 17 in Fleming Island, Florida. They planned to relocate an existing stormwater facility to another location on the project site. There are two ponds on the project site, a wet retention pond in the northwest and a dry detention pond in the southeast which fulfilled the purpose of controlling run- off/overflow.

Our project aim was to fill and grade the existing northeast pond and create a new stormwater facility next to the existing southeast dry detention pond. The new pond could be expanded and combined with detention pond. The purpose of this project was to maximize the land usage equally of north parcel for future developments or retail.

We used multiple engineering disciplines to carry out this project, such as Civil – AutoCAD Civil 3D model for basin area; environmental – Bentley’s StormCAD for hydraulic model and drainage calculation; and geotechnical – for reviewing soil reports and flood zones for the project site. The project also required modifying an existing environmental resource permit (ERP) from the St. Johns River Water Management District (SJRWMD) and the approval of the Clay County Board of County Commissioners. The project site had already passed the zoning requirements. We followed multiple environmental, land development and city planning codes to maintain ecological balance and sustainable development of the project.
