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