Environmental Summary
The OTA studied the area where the new interchange will be built at I-35 and Indian Hills Road. Here is what they found:
-
Relocations: The Oklahoma Department of Transportation (ODOT) previously purchased some of the needed property for this interchange. Approximately 3 additional businesses in the project area will be purchased by OTA. OTA is currently working with the property owners to complete these purchases and assist with moving costs.
-
Historic and Archaeological Resources: Experts walked the area and dug small holes to look for archaeological items. They also examined all of the buildings and structures 45 years of age and older to evaluate their historic significance. No significant historic or archaeological resources were identified. The Oklahoma State Historic Preservation Office and Oklahoma Archaeological Survey have reviewed and concurred with these findings.
-
Aquatic Resources: Biologists mapped all of the streams, ponds, and wetlands in the area. Crossings of the Little River and its tributaries will require a permit from the US Army Corps of Engineers for construction of bridges and culverts. This permit will be obtained closer to construction.
-
Protected Species: The project may affect habitat for the bald eagle, whooping crane, Arkansas River shiner, and the monarch butterfly. A bald eagle survey will be completed prior to construction and any active nests will be avoided. Certain activities such as fueling and storage of materials will be restricted within 300 feet of the Canadian River. The US Fish and Wildlife Service has agreed with these protection measures.
-
Hazardous Materials: Investigation identified a total of six (6) former salvage yards, underground storage tank facilities, and industrial facilities within the project vicinity. These sites are not expected to affect the construction of the project. If workers find contaminated soils during construction, they will stop work and follow procedures to protect the health and safety of people and the environment.
-
Farmland: The project will affect approximately 59 acres of farmland. The Natural Resources Conservation Service has determined that these impacts do not require any additional action.
-
Noise: A noise study was completed according to FHWA and ODOT policy. Noise impacts were identified at three homes, one business, and several areas along existing recreational trails. Noise walls were considered, but these walls either did not meet either noise reduction goals or cost per benefitted receiver established in the ODOT Noise Policy and will not be included in the project.
