The purpose of this Natural Resource Assessment was to characterize the existing conditions of the project site relative to threatened and endangered species and their habitat, ecological communities, land cover and vegetation, wetlands, soils, hydrology, archaeological and historical resources, and floodplains. The scope of work also included a 15% gopher tortoise survey. The project site is located southwest of the Homestead-Miami Speedway, south of Palm Drive and west of SW 142nd Avenue in Miami-Dade County, Florida (Section 27, Township 57 South, Range 39 East). A site location map is attached as Figure 1. A portion of the U.S. Geological Service (USGS) 7.5-Minute quadrangle map depicting the location of the subject site is attached as Figure 2. Elevation on-site from the quad map is approximately 0 to 5 feet and is relatively flat across the site. Portions of the site have previously been cleared, mass-graded, and filled.

Vegetative communities and cover types were classified according to the Florida Land Use, Cover, and Forms Classification System (FLUCFCS, Florida Department of Transportation, 1999). A FLUCFCS map of the project site is attached as Figure 4. A description of each land cover type, included below, characterizes dominant vegetation observed along random pedestrian transects, and does not represent an all-inclusive vegetative inventory. The acreage provided for each land cover is approximate, based on aerial photograph interpretation. FLUCFCS 190 – Open Land (±29 Ac.) This land use type consisted of a previously
