Traffic Impact Fee Administration

Adams County Regional Traffic Impact Fee

Local governments in Colorado have powers granted to them through state enabling legislation to impose transportation impact fees. Adams County imposes a regional traffic impact fee on new development to offset growth related impacts. The fee only partially captures the governmental expenditures associated with improving the county’s road system. For more information about the regional traffic impact fee, see Section 5-06 of the Adams County Development Standards & Regulations.

Proposed updates to the Regional Traffic Impact Fee:

Adams County’s current Transportation Impact Fee study was completed in 1998. Since then, the State of Colorado has implemented a new impact fee statute, and demographics, the real estate market, and capital cost of transportation improvements have changed, requiring an update of the fee study. Transportation impact fees are one-time payments for new development’s proportionate share of the capital cost of infrastructure. Transportation impact fees do have limitations and should not be regarded as the total solution for transportation infrastructure funding. Rather, they are one component of a comprehensive funding strategy to ensure provision of adequate public facilities. Transportation impact fees may only be used for capital improvements or debt service for growth-related infrastructure.

Adams County is considering updating their Transportation Impact Fees and commissioned an updated study; the county has been working with TischlerBise on this study since 2017. Community and Economic Development Department staff met with the Board of County Commissioners in a study session on Feb. 26, 2019, to present the findings of the draft report. The Transportation Impact Fee Study was finalized in March 2019 and will support any fees that are adopted.

More stakeholder outreach and public input will be solicited over the next several months. If you have any questions, please contact Jen Rutter at
