ZNo Critical Habitat is designated within the Project area for any of the species listed above(USFWS 2014b). 3Potential for occurrence is based on field surveys. No state or federally listed species were observed during field surveys. Of the species listed above, potential Northern leopard frog habitat and snowy egret foraging habitat is found within the Project area. In addition,the edges of the pond could provide a limited amount of migration stopover habitat for shorebirds (piping plover, least tern). However, any use birds is likely to be rare and short-term, as more likely suitable habitat is located elsewhere. GENERAL EFFECTS The E470 Authority intends to fill Sandy Acres gravel pit pond, which will permanently affect approximately 1.26 acres of wetlands and approximately 31.6 acres of open water. Waterfowl and fish habitat will be removed. Because wetland and water habitat will be eliminated,upland grassland habitat will expand. According to CPW personnel, all game fish (does not include sucker or carp species) will be salvaged and transported to other ponds and lakes (Winkle pers comm 2014). There would be no effect on migration routes for wildlife. The prairie dog colony located on the east side of the Project area may be disturbed by increased human activity during construction/filling; however,the town will not be directly affected. After the Project has been completed,the colony may expand due to the increase in grassland habitat. 7
