2022 ESPWPS Wildlife-Highway Mitigation Recommendations

This compilation of site-specific recommendations is provided as a standalone chapter accompanying the ESPWPS final report. Preliminary wildlife crossing mitigation recommendations for the top 5 percent highway segments in CDOT Regions 1, 2, and 4 were developed based on the findings of the field surveys and the latest research on the effectiveness of different mitigation strategies. These preliminary recommendations may be used to inform initial project planning and budgeting, although recommendations may be revised upon further project analysis.

2022 Updated Wildlife Valuations and Benefit-Cost Analysis (BCA) Tool

The Benefit-Cost Analysis (BCA) Worksheet was first developed for the WSWPS and updated for the 2022 ESPWPS. It functions as a tool for determining the benefits and costs of wildlife crossing mitigation. The output of the tool is a BCA ratio, which is calculated in three ways: (1) using current CDOT Traffic and Safety Engineering’s methods and valuations; (2) using current U.S. Department of Transportation methods and valuations; and (3) using the Wildlife Prioritization Study hybrid benefit-cost methods and valuations. For Wildlife Valuation see ESWPS Appendix E. This spreadsheet should be utilized for planning only. The calculations do not imply or provide any approval for grant funding and/or safety funding. Requests for grant funding and safety funding will still need to be completed through the process governed by CDOT via DTD and the Traffic & Safety Engineering Branch, respectively.
