Vantage to Pomona Heights Chapter 4 230 kV Transmission Line Project FEIS Environmental Consequences PAGE 4-149 4.5 RECREATION Impacts on recreation resources would be created as a result of the construction, operation, and maintenance of the Project and would be caused by the displacement or alteration of existing recreation land uses or activities. 4.5.1 Methods and Impact Types 4.5.1.1 Analysis Methods The recreation impact methodology was similar to the analysis of the land use resources and included: • Identifying the types of Project effects on recreation resources; • Evaluating the sensitivity of specific recreational uses to change; • Developing criteria for assessing impact intensity; • Assessing impacts based on Required Design Features (RDFs); • Introducing mitigation measures in specific locations to reduce impacts; • Evaluating residual impacts; and • Comparing alternatives based on recreation impacts. 4.5.1.2 Impact Criteria Resource sensitivity was considered in determining how susceptible to change recreational land uses would be to the introduction of the Project as described in Chapter 2. Impacts were based on sensitivity and impacts that could occur to recreational uses as a result of Project construction, operation, and maintenance. Sensitivity is a measure of the probable responses that a recreational use or activity would have to the direct and indirect impacts associated with the construction, operation, and maintenance of the proposed Project. Refer to Table 4.5-1 for recreational resource sensitivity. Table 4.5-1 Recreation Resource Sensitivity Classification RECREATION RESOURCE SENSITIVITY Developed Recreation Facilities High Trails High Planned Recreation Facilities and Trails Moderate Public and Private Hunting Areas Low Dispersed Recreation Areas Low Potential change describes the physical, operational, or social changes that could potentially occur to a recreation use or activity. Changes are brought about by: • Acquisition of land or property rights to accommodate the Project; • Installing the Project; • The physical presence and operation of the Project; and • Managing the right-of-way (ROW) and maintaining the transmission line. The potential for change from introducing the transmission line differs from one recreation use category to another with respect to what might be altered and to what extent. This potential for change is predicted by evaluating the environmental conditions, the Project description and Design Options, and RDFs.
