Citrus Park/East Bonita Stormwater Improvements

KCA was selected to provide the City of Bonita Springs with a hydrology and hydraulics (H&H) Study for the Citrus Park/East Bonita Stormwater Improvement project, which received funding from the Federal Emergency Management Act Hazard Mitigation Grant Program (FEMA HMGP). The Citrus Park and Morton Avenue area consists of a wide variety of land uses including single-family homes. Stormwater runoff is generally conveyed via open ditches and culverts. The Citrus Park private community, which has a system of gutters, inlets, and treatment ponds that outfalls into an existing ditch along East Terry Street. The ditches and culverts generally convey stormwater runoff west under I-75 at various places and outfall into the Imperial River. This area experienced significant flooding from the Invest 92 L and Hurricane Irma storm events.

The project included the design of a reservoir improving the existing Bonita Grande Aggregates mine on the property east of the Citrus Park community. The reservoir would be used for storage to improve the surrounding intercommunity drainage conveyance. This phase required significant updates to the Interconnected Channel and Pond Routing (ICPR) 4 watershed model. The model was updated to reflect construction permits such as Bonita Grande on the existing Bonita Grande Aggregates site and verifying the model inputs such as the Citrus Park pumps on and off elevations and discharge rate. The project also included design of control structures, pumps, drainage conveyance infrastructure as well as permitting through the South Florida Water Management District (SFWMD).

KCA assisted City staff in meeting FEMA HMGP funding requirements and training on the federal funding process (subrecipient compliance, Title VI and non-discrimination, Equal Opportunity Compliance [EOC], proprietary items, non-federal participating items, Uniform Act for Acquisition, accurate invoicing, etc.). KCA worked with the City to coordinate communication with the Florida Department of Emergency Management (FDEM) for a time extension.
