Cyntheanne Road Transportation Planning Study - Indianapolis ...

the project will not lessen the air quality of the area. If a proposed project
has not been included in the MPO Transportation Plan and the
Transportation Improvement Plan (TIP) approved by the Federal Highway
Administration, then an air analysis will be required to ensure the project
conforms to the State Implementation Plan (SIP). Projects considered
non-major in scope (bridge replacement on the essentially the same
alignment, road resurfacing, intersection reconstruction, traffic signal
modernizations, etc.) will not generate additional traffic volumes and will,
therefore, be exempt from an air analysis.
4.2.7 Noise:
A noise analysis was not completed for the existing roadway as part of this
study. Any improvements involving the addition of travel lanes or new
roadway alignment will require a noise analysis to determine the impact
on adjacent commercial and residential receivers.
4.2.8 Wetlands:
The National Wetlands Inventory (NWI) Maps issued by the United States
Fish and Wildlife Service for the McCordsville and Ingalls Quadrangles
indicate the presence of wetlands within the study area. Potential wetland
impacts exist at the crossing of Fall Creek for all alternates. These maps
are based on aerial photography and have not been field verified. Prior to
any construction activities, a wetland determination should be performed
to confirm the existence of the aforementioned wetlands. If jurisdictional
wetlands exist within the project area, a wetland delineation should be
performed to determine the amount of impact as a result of the project. A
report should be generated and submitted to the United States Army
Corps of Engineers and the Indiana Department of Environmental
Management for their concurrence. A permit and, depending on the
amount of impact, mitigation may be required.
4.2.9 Sole Source Aquifers:
There are no Sole Source Aquifers located near the study area.
4.2.10 Threatened & Endangered Species/Flora & Fauna:
The proposed project is within the range of the Federally endangered
Indiana Bat (Myotis sodalis) and the Federally threatened bald eagle
(Haliaeetus leucocephalus). The area surrounding the Geist Reservoir
contains adequate habitat for the Bald Eagle. Bald Eagles nest in tall trees
and cliffs near seacoasts, rivers and lakes feeding mainly on fish. The
Indiana bat utilizes wooded riparian areas and adjacent woodland uplands
for summer nursery habitat. Maternity colonies roost under loose bark of
trees and feed along stream corridors. Adult female Indiana bats exhibit
