Featured Projects

Chipola River Protection and Stormwater Mitigation Retention Pond

The project consisted of construction of a 6.75-acre stormwater pond, north of Prough Drive, to retrofit what was untreated watershed, making treated stormwater available to irrigate 7.22-acres on the Chipola College campus. This project will reduce groundwater use for irrigation, improving water quality of discharge downstream into the Chipola River, and reduce flooding to the campus and to River Forest Road. In addition, this project brings aesthetic beauty to the campus, for its staff, students, and community members.

The DHM team was responsible for planning, civil design, permitting, grant funding and administration, project management, and construction engineering inspection.

The project included earthwork, installation of a bentonite clay pond liner, irrigation system with irrigation pump system, drainage culverts, concrete ditch paving and structures, sod and landscaping.

Collaboration: The DHM team coordinated efforts with the City of Marianna, Chipola College, Northwest Florida Water Management District, FEMA, and all other stakeholders and contractors to achieve successful project completion.
