Introduction: The total site is approximately 30.25 acres in size and is located at -800 5’ 33.785” (-80.0927180) West Longitude and 260 45’ 13.626” (26.7537850) North Latitude approximately 3,760 feet (3/4 mile) south of 45th Street on the north side of Village Boulevard in West Palm Beach, Palm Beach County, Florida (see Figure 1, Site Aerial). The wetland is located in the northeast end of the overall site. The overall site conditions are an open urban field / primarily dry prairie and the wetland mitigation area will be in the area that is now an isolated pond, and entrained area with wetland characteristics. The Florida Land Use Cover and Forms Classification System (FLUCCS) designation for the subject parcel is “Open Land- Urban” / “Herbaceous Prairie” (FLUCCS 1900 / 3100). The northern boundary is a “Lake and Reservoir” (FLUCCS 5300), to the south is Village Boulevard “Roads and Highways” (FLUCCS 8140), the westerly adjacent properties contain “Medium Density, Fixed Single Family Units” (FLUCCS 1210) and “Commercial and Services” (FLUCCS 1400). The eastern boundary is Interstate 95 “Roads and Highways” (FLUCCS 8140). The site specific FLUCCS and Natural Systems found on the site include an open urban prairie and shrubby wetland with freshwater marsh (FLUCCS 6172, 6410), (see Figure 2, Current Conditions Map). The proposed wetland mitigation area will be in the areas that are now exotic dominated marsh and shrubby wetlands. These areas are dominated by open water, spatterdock (Nuphar lutea), cattail (Typha spp.), and Brazilian pepper (Schinus terebinthifolius).

Vegetation: The ground cover and herbaceous vegetation along the perimeter of the proposed wetland area is dominated by various grasses and herbaceous such as false buttonweed (Spermacoce glabra), umbrella grass (Hydrocotyle umbellata), buttonweed (Diodia virginiana), St. Augustine grass (Stenotaphrum secundatum), creeping oxeye (Wedelia triloba), flat sedge (Cyperus filiculmis), torpedo grass (Panicum repens), Bahia grass (Paspalum notatum) and herb-of-Grace (Bacopa monnieri). Even though these plants are wetland plants, removal and replacement with marsh plants is proposed as part of the wetland mitigation plan.

The areas within the limits of the pond that will become part of the wetland mitigation area are currently dominated by cattail and torpedo grass. The vegetation in these areas will be removed and replaced with suitable freshwater marsh vegetation

Site Photo #2: Current site conditions at the proposed wetland mitigation area.

The area of the proposed wetland mitigation area “deep marsh” is currently unvegetated or vegetated with sparse spatterdock or bladderwort (Utricularia spp.). These areas will be filled to make them more suitable for growth of deep marsh vegetation according to the planting plan and project design plans in the permit.

Soil Survey Soils: The soils on the site contain both Udorthent and wetland soils. The area of the proposed wetland mitigation site contain suitable wetland soils that will be retained onsite for use in the final wetland mitigation area as a planting media.

Site Photo #4: Typical soil profile onsite. The soil conditions documented on the site suggested that the majority of the site had been filled with Udorthent type soils. The soils are dry in the upper 12 inches and generally uniform in color at a light brown (10YR 5/1) to (10YR 6/2) mixture. In some soil plugs, the upper 2 inches contained a dark brown soil layer (10YR 4/2). However, the areas adjacent to the isolated pond contains soils that have a 5-inch-thick dark brown (10YR 2/1) layer of mucky mineral soil over 10 inches of light brown

(10YR 6/3) sandy soil. The lower layers of the soil profile contain redox features that are orange (10YR 5/8) in color. This soil type is consistent with wetland soil conditions and will be incorporated into the wetland mitigation area to provide suitable wetland planting media for growth and development of wetland vegetation.

Surface Hydrology: The area of the proposed wetland mitigation site is either too deep or too shallow for a freshwater marsh community. Depths currently range in this area between three feet above design water elevation (DWE) to approximately 7 feet below DWE. The hydrology is controlled by stormwater structures offsite and the project will include additional structures in the onsite plan that will be used to control the water levels in the lakes and wetland mitigation area. Soils will be used to fill the areas that are too deep in the wetland mitigation area and scraping will be employed to lower the areas that are too high. An as built survey will be prepared prior to wetland installation to confirm suitable wetland elevations.
