Showing ordinances that apply to Knollwood, IL
Knollwood is an unincorporated community (population 2,121) in Lake County, Illinois. Because Knollwood is not an incorporated city, it does not have its own municipal code. Instead, Lake County ordinances apply directly to properties here. The heritage & protected trees rules below are the ones that govern your area.
Lake Forest and Highland Park designate heritage/landmark trees, typically oaks, hickories, and specimen hardwoods 24+ inches DBH. Removal requires City Council or commission approval, rarely granted except for imminent safety hazards.
Lake Forest's Tree Preservation Ordinance (Code Ch. 97) identifies heritage trees by species, size (generally 24+ inches DBH), and historical/ecological value, with particular protection for bur oak, white oak, and other native hardwoods characteristic of the Openlands-designated ravine system. Removal requires Tree Review Committee approval and typically is denied except for dead, hazardous, or disease-killed trees. Highland Park Code Ch. 102 similarly protects heritage trees in ravine corridors and along the Lake Michigan bluff, with enhanced review for oak-hickory communities. Libertyville designates landmark trees through its Environmental Advisory Commission. Protected trees must be shielded by root-zone fencing during construction, with penalties for root damage, soil compaction, or trunk injury. Unincorporated Lake County does not have a formal heritage tree program but applies the UDO's native vegetation preservation requirements during development. Residents may nominate candidate trees through municipal forestry divisions.
Unauthorized removal of heritage tree: $2,500-$25,000 per tree plus replacement at 3:1 caliper-inch ratio. Construction damage: $1,000-$10,000 plus remediation. Violations may trigger stop-work orders on adjacent development projects.
