Johnson Engineering completed the design, specifications, and permitting through SFWMD and USACE for a new primary outfall structure, Weir 29. The project is currently nearing the end of construction. Performed entirely in-house, the design included a fixed-crest concrete weir with two slide gates with motorized actuation, remote monitoring, and remote operation. The Supervisor Control and Automatic Data Acquisition (SCADA) system was designed to be compatible with the existing remote monitoring and operating system currently used by the City of Cape Coral.
At the beginning of the detailed design phase of this project we critically reviewed the conceptual design provided and found that the downstream culverts under the roadway were shown to be the controlling factor, not the proposed weir. This allowed the weir design to be reduced from 68 feet to 20 feet, resulting in considerable cost savings for the City while providing the same level of service.
Our team looks forward to assisting the City on future stormwater projects. For more information, contact Jordan Varble, PE at email@example.com.
