September 20, 2018 Jeff Sedloff June Engineering Consultants 32 West Plant Street Winter Garden, FL 34787 Proj: Folsom Subdivision Site – Hillsborough County, Florida Parcel ID #U-21-28-20-ZZZ-000002-13230.0 (BTC File #100-76) Re: Environmental Assessment Report Dear Mr. Sedloff: During September of 2018, Bio-Tech Consulting, Inc. (BTC) conducted an environmental assessment and wildlife survey of the approximately 19.05-acre Folsom Subdivision Site. This site is located at the physical address of 9737 Commodore Drive, within Section 21, Township 28 South, Range 20 East; Hillsborough County, Florida (Figures 1,2 & 3). The environmental assessment included the following elements. • Review soil types within the project boundaries • Evaluation of land use types/vegetative communities • Review for occurrence of protected flora and fauna • Review of development constraints and permitting SOILS According to the Soil Survey of Hillsborough County, Florida, prepared by the U.S. Department of Agriculture (USDA) Natural Resources Conservation Service (NRCS), two (2) soil types occur within the subject property boundaries (Figure 4). These soils include the following: Jeff Sedloff – June Engineering Consultants Folsom Subdivision Site – Hillsborough County, Florida (BTC File #100-76) Environmental Assessment Report Page 2 of 7 • Candler fine sand, 0 to 5 percent slopes (#7) • Tavares-Millhopper complex, 0 to 5 percent slopes (#53) Candler Fine Sand; 0 to 5 percent slopes (#7) is a nearly level to gently sloping, excessively drained upland soil mapping unit, which may include up to 18% of dissimilar soil types. Typically Candler fine sands have a surface layer of dark gray fine sand about 6 inches think. A seasonal high water table is at a depth of more than 80 inches. Permeability is rapid and available water capacity is very low. The soil is suitable for citrus crops and moderately suitable for pasture or sand pine. Associated with its permeability, the soil is known for droughtiness and leaching of soil nutrients. Consequently, soil erosion, the instability of cut banks and groundwater contamination associated with seepage are recognized management concerns. Tavares-Millhopper complex; 0 to 5 percent slopes (#53) are nearly-level-to-gently-sloping, moderately-well drained soils found in low-lying areas of uplands and on low ridges of flatwoods. Generally, this soil unit is composed of about 63 percent Tavares soil and 26 percent Millhopper soils, although dissimilar soils may comprise up to 13 percent of these areas. Tavares soil surface is dark grayish brown fine sand to a depth of 6 inches supported by pale brown sand to a depth of about 32 inches. The surface layer of Millhopper soil is about 4 inches of dark gray fine sand over subsurface layers of brown fine sand to a depth of 9 inches and light yellowish brown fine sand to about 25 inches. Tavares soil has a seasonal high water table at a depth of 40 to 80 inches for more than 6 months, which recedes to a depth below 80 inches during extended dry periods. Millhopper soil has a seasonal high water table at a depth of 40 to 60 inches for 1 to 4 months per year, which recedes to 60 to 72 inches for 2 to 4 months. Tavares soils have rapid permeability while Millhopper soil permeability is rapid in the surface and subsurface layers and moderate in the subsoil. Available water capacity is very low and low for Tavares and Millhopper soils, respectively. The common land uses on these soils include pasture, home sites and urban development, although some areas have developed cultivated crops and citrus on these soils. The main management concerns associated with this mapping unit include droughtiness, leaching of soil nutrients, instability of cut banks and the potential for groundwater contamination. The Florida Association of Environmental Soil Scientists (FAESS) does not consider main components or inclusions from soil types associated with the subject site to be hydric. This information can be found in the Hydric Soils of Florida Handbook, Fourth Edition (March 2007). Jeff Sedloff – June Engineering Consultants Folsom Subdivision Site – Hillsborough County, Florida (BTC File #100-76) Environmental Assessment Report Page 3 of 7 LAND USE TYPES/VEGETATIVE COMMUNITIES The Folsom Subdivision Site currently supports two (2) land use types/vegetative communities within the subject property boundaries (Figure 5). These land use types/vegetative communities were identified utilizing the Florida Land Use, Cover and Forms Classification System, Level III (FLUCFCS, FDOT, January 2004). The upland land use types/vegetative communities within the subject property consists of Low Density Residential (110) and Improved Pasture (211). There are no wetlands/surface waters within the subject property boundaries. The following provides a brief description of the land use types/vegetative communities identified within the Folsom Subdivision Site. Uplands: 110 Residential, Low Density (approx. 0.65 acres) In the southern-central portion of the site, is a mobile home residence that is best classified as Residential, Low Density (110), per the FLUCFCS. Vegetative species identified within this area consists of bahiagrass (Paspalum notatum), live oak (Quercus virginiana), and muscadine (Vitis rotundifolia). 211 Improved Pastures (approx. 18.40 acres) The majority of the property is active and maintained pasturelands and this area is best classified as Improved Pastures (211), per the FLUCFCS. Vegetative species identified within this area consists of bahiagrass (Paspalum notatum), live oak (Quercus virginiana), laurel oak (Quercus laurifolia), water oak (Quercus nigra), cabbage palm (Sabal palmetto), slash pine (Pinus elliottii), camphortree (Cinnamomum camphora), guineagrass (Megathyrsus maximus), lantana (Lantana spp.), rattlebox (Crotalaria spp.), American pokeweed (Phytolacca decandra), yellow thistle (Cirsium horridulum), caesarweed (Urena lobata), muscadine (Vitis rotundifolia), greenbriar (Smilax spp.), passionflower (Passiflora coccinea), beggar ticks (Bidens alba), common ragweed (Ambrosia artemisiifolia), climbing hempvine (Mikania scandens), balsam apple (Momordica balsamina), tropical soda apple (Solanum viarum), and dogfennel (Eupatorium capillifolium). Wetlands/Surface Waters: There were no wetland or surface water land use types/vegetative communities identified within the Folsom Subdivision Site property boundaries. Jeff Sedloff – June Engineering Consultants Folsom Subdivision Site – Hillsborough County, Florida (BTC File #100-76) Environmental Assessment Report Page 4 of 7 WILDLIFE AND PROTECTED SPECIES Using methodologies outlined in the Florida’s Fragile Wildlife (Wood, 2001); Measuring and Monitoring Biological Diversity Standard Methods for Mammals (Wilson, et al., 1996); and Florida Fish and Wildlife Conservation Commission’s (FFWCC’s) Gopher Tortoise Permitting Guidelines (April 2008 - revised May 2017); an assessment for “listed” floral and faunal species was conducted at the site. This assessment included both direct observations and indirect evidence, such as tracks, burrows, tree markings and vocalizations that indicated the presence of species observed. The assessment focused on species that are “listed” by the FFWCC’s Official Lists - Florida’s Endangered Species, Threatened Species and Species of Special Concern (May 2017) that have the potential to occur in Some County (see Table 1). The following is a list of those wildlife species identified during the evaluation of the site: Reptiles and Amphibians green anole (Anolis carolinensis) Cuban brown anole (Anolis sagrei) Birds Blue Jay (Cyanocitta cristata) Northern Mockingbird (Mimus polyglottos) Northern Cardinal (Cardinalis cardinalis) Red-shouldered Hawk (Buteo lineatus) Mammals eastern gray squirrel (Sciurus carolinensis) nine-banded armadillo (Dasypus novemcinctus) None of the above identified species are listed in the FFWCC’s Official Lists - Florida’s Endangered Species, Threatened Species and Species of Special Concern (May 2017). The following provides a brief description of particular wildlife species as they relate to the development of the site. Bald Eagle (Haliaeetus leucocephalus) State protected by F.A.C. 68A-16.002 and federally protected by both the Migratory Bird Treaty Act (1918) and the Bald and Golden Eagle Protection Act (1940) In August of 2007, the US Fish and Wildlife Service (USFWS) removed the Bald Eagle from the list of federally endangered and threatened species. Additionally, the Bald Eagle was removed from FFWCC’s imperiled species list in April of 2008. Although the Bald Eagle is no longer protected under the Endangered Species Act, it is still protected under the Bald and Golden Eagle Protection Act, the Migratory Bird Treaty Act, and FFWCC’s Bald Eagle rule (Florida Administrative Code 68A-16.002 Bald Eagle (Haliaeetus leucocephalus). Jeff Sedloff – June Engineering Consultants Folsom Subdivision Site – Hillsborough County, Florida (BTC File #100-76) Environmental Assessment Report Page 5 of 7 In May of 2007, the USFWS issued the National Bald Eagle Management Guidelines. In April of 2008, the FFWCC adopted a new Bald Eagle Management Plan that was written to closely follow the federal guidelines. Under FFWCC’s new management plans, buffer zones are recommended based on the nature and magnitude of the project or activity. The recommended protective buffer zone is 660 feet or less from the nest tree, depending on what activities or structures are already near the nest. A FFWCC Eagle permit
