TRANSPORTATION IMPACT FEES

Transportation Impact Fees

CHD4 has partnered with Canyon County and the Cities of Star and Middleton to establish development impact fees to fund transportation system improvements necessary to accommodate new growth and development.

Impact fees are authorized by Idaho Code Title 67 Chapter 82 for public infrastructure such as roadways.  They are collected from each new development (residential, commercial or industrial) at the time of access permit or building permit issuance, and in proportion to the traffic impact resulting from the new construction.  City of Star enacted an ordinance September 13, 2021, and Canyon County enacted an ordinance July 20, 2022 authorizing the collection of transportation impact fees within the Mid-Star Service Area.  By agreement with the County, CHD4 will collect, track, and expend these fees for specific transportation improvements within this area.  The Cities of Star and Middleton will collect impact fees for developments within their city limits.  CHD4, Star, and Middleton will work cooperatively to fund and construct intersection and roadway improvements within the service area.

Mid-Star Service Area

Mid-Star Service Area

Named for the Middleton-Star area, this service area includes all of Canyon County north of the Boise River and east of Interstate 84, as well as a small area south of the Boise River lying north of Lincoln Rd between KCID Rd and Midland Rd.  This area is currently the fastest growing part of the highway district and rural Canyon County, and was selected for study and implementation of an impact fee program to address transportation needs brought about by rapid new growth in the area.

Mid-Star Capital Improvement Plan

The Mid-Star CIP details forecast growth, current and projected traffic needs, and a project list to meet needs arising from anticipated growth during the 2020 - 2040 timeline.

Mid-Star Service Area Impact Fees

Individual Assessments

Developments may request a written certification of an impact fee prior, or an individual assessment of the proportionate share of impacts from a particular development.  Individual assessments typically require a Traffic Impact Study at applicant's expense to support exceptions from the adopted impact fee schedule.  See the Individual Assessment Guidelines below for allowable considerations.
