Since the Draft AUAR was published, the DNR has added another Blanding's turtle sighting in the vicinity of the campus to their database based on adjacent resident sightings (see the DNR's November 14, 2002 letter in Appendix C). Almost all of the land between the project site and the areas where turtles have been identified is developed, medium density, residential land and is not considered favorable habitat for Blanding's turtles. Nevertheless, there is a possibility that Blanding's turtles could use portions of the site, particularly the shallow wetland (see Figure 10, Wetland L) and surrounding undisturbed sandy loam (132B and 132C) upland located at the northwest comer of the property. Refer to Items 12 and 19 for more details on wetlands and soils on the campus. No survey of the AUAR study area has been conducted to determine the presence of Blanding's turtles. Coordination with the DNR Natural Heritage division confirms that a survey of the study area is not necessary as the recommended avoidance and mitigation measures identified below will be implemented as practicable. A list of recommendations for avoiding and minimizing impacts to Blanding's turtles and their habitat is included in the DNR report. These recommendations will be implemented where feasible. The measures that will likely be appropriate for project construction include: I) Placement of silt fencing around construction areas to keep turtles out of construction areas in the spring. 2) Notifying contractors of the possibility of threatened turtles III the area and instructions on how to avoid harm to turtles if they are spotted. 3) Minimization of impacts to wetlands on the site. 4) Preservation of un-mowed upland buffer around wetlands on the site. 5) Preservation of some undisturbed upland at the northwest comer of the site. 12.
