Enterprise Park to Crooked Lake 115 kV Transmission Line March 2012 Environmental Assessment 5. Affected Environment, Impacts, and Mitigation The construction of a transmission facility involves both short- and long-term impacts. An impact is a change to the pre -construction environment as a direct or indirect result of the proposed action and may be positive or negative. Direct impacts are caused by the action and occur at the same time and place. Indirect impacts are caused by the action and occur later in time, but are still reasonably foreseeable. This section describes the potential impacts on resources and the possible mitigation measures intended to avoid, minimize, or mitigate impacts caused by the construction and future operation and maintenance of the proposed transmission facility. 5.1. Human Settlement The Project has the potential to affect various resources related to human settlement. Potential effects related to proximity to structures, aesthetics, noise, interference with public services and utilities, archaeological and historic resources, and safety and health are addressed in this section. 5.1.1. Proximity to Residential Structures Residences are located along the roads and property lines paralleled by the proposed route and Route Segment Alternative A (Figure 4.) To compare the route alternatives, residences in the Project area were identified, and the number of residences within 35 feet, 36-135 feet, and 136-300 feet of the proposed alignment for the Proposed Route and Segment Alternative was tabulated. Although 17 homes are within the maximum ROW required for the transmission line, the Applicant has stated that no residential displacement will need to occur in order to construct and operate the transmission line. The National Electric Safety Code (NESC) and Applicant standards require certain clearances between transmission line facilities and buildings for safe operation of the transmission line. Therefore, the Applicant would acquire a ROW for transmission lines that is sufficient to maintain these clearances. The Applicant has stated this is possible by reducing the ROW required, and by sharing existing ROW, such as road corridors. This information is presented in Table 5.1. Table 5.1 Number of Residences within 300 Feet of the Proposed Route Alignment Resource Category Proposed Route Segment Route Alternative A Number of Residences 0-35 feet from route 17 17 alignment Number of Residences 36-135 feet from route 60 40 alignment Number of Residences 136-300 feet from 172 172 route alignment Total number of residences within 300 feet of 249 229 route alignment 22
