RI Map Inventory The Rhode Island Low Impact Development (LID) / Green Infrastructure (GI) Inventory is an online tool showing how these types of stormwater practices are being used throughout Rhode Island. You can search for LID sites two ways: 1. Explore the Map Search by town or type of treatment practice (map will open in a new window) 2. Browse the Complete List Organized by type of treatment practice. You can also find companies that design or install these LID/GI practices in each site description. We hope seeing how these practices are being used throughout Rhode Island is useful for anyone planning to use these innovative techniques.
