 How much should developers pay to offset the cost of new construction? City of Grand Junction levies impact fees and revisits those every five years. The impact fee study is underway right now and open for public input. The impact fees cover things like streets, parks, and public safety facilities. A community meeting about the fees is set Thursday morning at 10 30 in the fire department training room on Ute Avenue. You can also weigh in at engagegj.org.
