Hawaiʻi Low Impact Development (LID) Atlas
The Hawaiʻi LID Atlas is a collection of alternative stormwater management practices currently installed across the state. The Atlas is hosted by the National Nonpoint Education for Municipal Officials (NEMO) Network and the University of Hawaiʻi Sea Grant Program.
It is an online resource providing geo-referenced examples of green infrastructure and low impact development for stormwater management. You can browse the Atlas by either selecting a town, land use type, project type, or by simply clicking on pinned sites.
You can add your own project to the atlas by filling out the Hawaiʻi LID Atlas Submission Form.
