PROJECT DESCRIPTION

This project includes two sections of channel conveyance improvements along the main stem of Little Cypress Creek, L100-00-00. The first section (L100-E002) runs from approximately 6,300 feet downstream of Cypress Rosehill Drive downstream to Telge Road and the second (L100-E001) runs from Telge Road downstream to the confluence with Cypress Creek, K100-00-00.

This project will mitigate for future development in the watershed while also reducing the current risk of flooding for residents. Natural channel design elements are designed to mitigate for environmental impacts to Little Cypress Creek, which is a natural stream and protected under federal law.

Bond ID F-26 includes funding for the development of the Little Cypress Creek Frontier Program Master Plan, as well as for the channel conveyance improvements. These improvements will develop a wider and deeper channel corridor that is between 330’ and 750’ wide, with space for Little Cypress Creek to more naturally meander at the bottom of the channel. This design will increase the capacity of Little Cypress Creek to convey stormwater, while compensating for any loss in the stream’s environmental value.

The Flood Control District is a no adverse impact agency, which means that development and infrastructure projects cannot send stormwater to flood another area. These channel conveyance projects will be built in conjunction with nine expanded or newly constructed stormwater detention basins that will temporarily hold excess stormwater during rain events.

This project is part of the Little Cypress Creek Frontier program that will reduce the risk of flooding in the Little Cypress Creek watershed for more than 3,200 structures in the Atlas 14 1 percent (100-year) floodplain and will reduce that floodplain by more than 5,800 acres.
