What is an LMD? Landscape Maintenance Districts (LMDs) were created many years ago by developers as a way for property owners to pay for enhanced landscaping and improvements beyond those generally provided by the city. Each district is responsible for maintaining all irrigation and sprinkler systems, turf, trees, shrubs, and bushes in medians and public rights-of way. Monies collected from LMD assessments are set aside for the exclusive benefit of each district and can only be used for maintenance and improvement of that specific district. Many homeowners in north Poway are assessed on their property taxes under LMD 86-1. (To determine if your property is part of an LMD, check your property tax statement.)
