Aurora, CO Tree Protection: Tree Replacement Requirements (2026)

Tree replacement ordinances vary by jurisdiction in Arapahoe County. Aurora City Code §94-352 requires replacement of any ROW tree removed with a city-approved new tree, typically 2-inch caliper minimum at planting, following the Aurora-approved species list emphasizing drought-tolerant and non-invasive varieties. Replacement ratios range from 1:1 for healthy-removed trees to 2:1 or 3:1 for larger specimens. Centennial Municipal Code §12-10 (landscape standards) requires tree preservation and replacement in new development, with minimum 2-inch caliper and approved native/adapted species including bur oak, Kentucky coffee tree, honeylocust, and hackberry. Cherry Hills Village Municipal Code §18-1 enforces stricter ratios (up to 3:1) for removed specimens. Approved species lists prioritize Colorado-adapted trees avoiding invasive species like Russian olive and Siberian elm. Fee-in-lieu payments to city tree funds (Aurora Tree Trust Fund) are allowed when on-site replacement is infeasible, typically $350 to $1,000 per required tree. Maintenance period: 1-2 years to ensure establishment, with dead replacements required to be re-planted. Colorado's water restrictions impact replacement selection toward xeric species.
