Each year the City of Sioux Falls receives complaints regarding property damage, personal injury, and general nuisance from low hanging branches over streets and sidewalks. This is a concern for safety. City ordinance identifies the abutting property owner as ultimately responsible for any damage or injury caused by low-hanging branches. In an effort to keep streets and sidewalks safe, the City of Sioux Falls Forestry Division inspects trees for low-hanging branches. The inspectors will determine if trimming is needed and the property owner will be notified.

Project T.R.I.M. is structured as a five-year cyclic street tree trimming program. The city is divided into fi ve districts with one district being surveyed each year. A district is divided into three sections with each section being surveyed at a specific time during the year, (first week in February, third week in June, or third week in September.) Please refer to the map for the survey.
