Full Breakdown
Rockford's historic preservation ordinance singles out large trees for protection wherever a property sits inside a designated historic district or carries a landmark designation. A "significant tree" is defined as one at least 18 inches in diameter, and removing one is expressly carved out of the "ordinary maintenance" exemption that otherwise lets owners landscape freely without commission sign-off. Take one down without authorization and the Historic Preservation Commission can fine the owner not less than $500 under the chapter's violations section.
Violations & Fines
$500 minimum fine per unauthorized removal of a significant tree from a historic district or landmark site.
