The fact that postal code boundaries do not always match city boundaries can cause confusion for residents when they call for services. If you want to know for sure that you truly live inside the city limits of Highland, call or come to City Hall and check the detailed City of Highland street map published annually by the Highland Chamber of Commerce.

Tree Trimming

Highland has a contract with a private tree maintenance service to trim trees. The contractor schedules work approximately twice a year. The city’s goal is to trim trees within the city’s right-of-way once every five years. The objective is to maintain the health of the trees and provide vehicle and pedestrian clearances. Utility clearances are done by the utility owners, not the city.
