Maple Grove, MN Landscaping Rules: Tree Removal & Heritage Trees (2026)

Maple Grove first adopted a Tree Preservation ordinance in 1994 and now regulates significant tree removal under city code Chapter 36 (Zoning), Article VII, Division 6. The ordinance keys off trunk diameter measured at breast height (DBH). Removal of trees having a trunk diameter of eight inches or more DBH triggers regulation, and development or lot alteration affecting such trees can require a certified survey of the lot identifying the location, size, and species of all trees eight inches DBH or larger, indicating which trees are to be removed, which saved, and any required replacement trees. The tree inventory must be prepared by a qualified professional such as a forester, natural resources specialist, certified arborist, or landscape architect. Trees designated for preservation must be protected during work, typically by a highly visible fence at the projected dripline. Where removal exceeds what the ordinance allows or occurs without city approval, replacement plantings are required; at planting the trunks of replacement deciduous trees must be at least 2.5 inches DBH (replacement standards appear in Sec. 36-729). The ordinance provides an exception for trees the community development director or a certified arborist determines to be diseased, dying, or dead, which is significant in a region with oak wilt and emerald ash borer. Because the regulation is tied to overlay districts and development thresholds, a homeowner removing a small ornamental tree generally is not affected, but anyone clearing larger trees or doing site work should confirm requirements with the city's Community Development Department before removal.
