Property Maintenance
Property maintenance activities are essential for the upkeep of residences, commercial buildings and landscaping; Property managers and contractors should use Best Management Practices (BMPs) to prevent the residue from these activities from reaching our storm drains and flowing untreated to our streams and the ocean.
The City and County of Honolulu developed a Property Maintenance Toolkit for Storm Water Compliance as a guide for property managers to implement practices to protect our water quality.
You can download the entire toolkit below — or scroll down to select just the pages you need.
