The proposed dredge footprint is approximately 1.61 acres. The project area is located under and adjacent to Johns Pass Bridge. The Florida Department of Transportation (FDOT) has authorized dredging around the Bridge and specified a 15-foot buffer between the dredge template and the bridge pilings and footings. The seaward limit of the dredge area ranges from approximately 102 to 140 feet from Hubbard’s Marina boardwalk. The minimum distance from the dredge template to the federal navigation channel is 121 feet. The dredge template is shown in detail in the attached Permit Drawings. The template has a proposed dredge depth that ranges from -10 to -12.7 feet NAVD, with a 2-foot over dredge allowance. An approximate volume of 12,897 cubic yards will be removed from the area. Side slopes will be cut at 1 vertical foot to 5 horizontal feet. The dredged material will be dewatered in the city owned parking lot north of Johns Pass and transported to a disposal site
