Tampa, Florida/Aurora, Colorado – Dewberry, in association with Merrick & Company, has been retained by the St. Johns River Water Management District to provide topographic data collection and processing for the Central Florida Coordination Area Surface Elevation Dataset project. As an agency of the state of Florida, the District is responsible for managing groundwater and surface water in all or part of 18 counties in northeast and east-central Florida. During this project, the first task order under Dewberry’s three-year contract with the District, the team will use the latest in light detection and ranging (LiDAR) technology to provide accurate information for a 320-square-mile area. When completed, the data acquisition process will provide new topographic data in support of water surfacing modeling and other engineering projects at the District.
The joint survey covers approximately 3.6% of the 7.8-million-acre St. Johns District. The collected data will be used to support the District’s core missions of effectively managing water supply, surface water resource protection, and flood protection. By using the latest technology in LiDAR, the team will be able to provide a higher level of accuracy in data than is typically found with traditional surveying technologies. This increase in accuracy provides a higher level of quality in the base information the District uses, thus allowing the District to derive improved water and surface models.
During the project, breaklines will be collected for all significant hydrographic features, including closed water body features, linear hydrographic features including hydro connectors, coastal shorelines, island features, road features, bridges and overpasses, and seawalls. The final deliverables also include contours at 1’ and 2’ intervals, as well as a comprehensive set of reports and metadata.
