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.

Wild Animal Benefit-to-Cost Analysis Spreadsheet

This Excel spreadsheet was developed for the benefit-to-cost analysis conducted in the Western Slope Wildlife Prioritization Study. 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.
