Low Impact Development Atlas

The Low Impact Development Atlas features innovative stormwater practices across the country.

The National Low Impact Development (LID) Atlas highlights geo-referenced examples of innovative low impact development stormwater practices across the country. The goal of this project is to encourage and educate communities and others about LID practices by providing specific, local examples. By sharing information, LID projects can serve as models for communities trying to address stormwater and growth-related issues.

This tool was created by the Connecticut Nonpoint Education for Municipal Officials (NEMO) Program, the National NEMO Network and the California Center for Water and Land Use.


The Atlas is built into Google Maps and can be navigated easily. You can search for projects by type and/or state, and clicking on a map marker will open up a bubble with information on that particular project. If you need assistance in using the Atlas, the NEMO Network maintains a YouTube page with videos on how to use the Atlas.
