Wetland replacement would be required to mitigate for wetland impacts. Depending on the location for replacement approved by the RCWD, the required mitigation will ensure that the amount of wetland at or near the project area will remain the same or increase. 5. Fish, Wildlife, and Ecologically Sensitive Resources. The project site is located within an area of residential homes, commercial and retail, and roadways. Though it is essentially fully developed, there are a number of waterbodies on the edges of the area that provide habitat for fish and other wildlife. Waterbodies include wetlands, Clearwater Creek, and Centerville Lake. Wildlife species likely to be present in the project area include raccoon, rabbit, squirrel, fox, deer, egret, heron, goose, duck and other waterfowl, hawk and other raptors, songbirds and other bird species; small amphibians and reptiles may also be present. Fish species identified in area lakes include walleye, northern pike, black crappie, bullhead, yellow perch, largemouth bass, carp, sunfish, and white sucker. Because of the proximity to Centerville Lake and Clearwater Creek, erosion and sediment control will be important. Best Management Practices will be used during construction of the project and may include silt fence, rock construction entrances, temporary sediment traps, biorolls, rip rap, inlet protection, temporary seeding and mulch. The DNR Natural Heritage and Nongame Research Program was recently contacted regarding the potential presence of threatened or endangered species, as well as other rare or sensitive biological resources in the vicinity of the project. The response letter (provided in Attachment 1 of the EAW) indicated that one threatened species (Blanding's Turtle) was historically identified in 1989 crossing a road south of Centerville. This species is found primarily in shallow wetlands (1-3 feet deep), but nest in open, sandy uplands up to one mile from wetlands. The project area is not within a known state- wide importance priority area, where greater protection is recommended to protect Blanding's Turtles. The DNR provided recommendations for avoiding and minimizing impacts to this species; the DNR response letter with recommendations was provided as Attachment 1 to the EAW. All of the recommendations applicable to the project and the project area will be implemented except for the recommendation regarding road curbing. One of the primary goals of the proposed redevelopment project is to create a pedestrian-friendly downtown area. In that regard, barrier style curbs are needed for the roads in the project area to provide for pedestrian safety. Centerville Downtown Redevelopment Page 19
