Rockville's Forest and Tree Preservation Ordinance (Chapter 10.5) prohibits residents from pruning, removing, or conducting any tree care on trees located in the public right-of-way or city parks without authorization. Private trees may be trimmed by the property owner, but any work affecting significant trees requires compliance with city forestry standards.
Rockville maintains strict regulations on tree trimming through its Forest and Tree Preservation Ordinance (FTPO) in Chapter 10.5 of the city code. It is unlawful for residents to prune, remove, plant, or conduct any other tree care activity on trees in the public right-of-way, city parks, or woodlands without authorization from the City Forester. Performing tree care on a roadside tree without a permit can result in fines and enforcement action by the city and the Maryland Department of Natural Resources Forest Service. For trees on private property, owners may perform routine maintenance trimming, but work affecting significant trees (those with a diameter exceeding 4 inches measured 12 inches above the ground, or flowering trees exceeding 2 inches) should follow proper arboricultural practices. The city's Forestry Division manages street and park trees and responds to requests for pruning of city-owned trees that pose hazards or interfere with utility lines. Rockville encourages residents to hire certified arborists for significant tree work. The city's technical guides for exterior alterations include landscaping and tree standards that apply in historic districts and planned development zones.
Unauthorized pruning or damage to public trees can result in fines and required mitigation under the FTPO. The Maryland DNR Forest Service may also enforce violations related to roadside trees. Damage to significant trees during construction can trigger stop-work orders and mandatory replacement planting requirements.
