Resource Rain Chattanooga: Low Impact Development (LID) Design Challenge is a design competition jointly sponsored by The City of Chattanooga, Chattanooga-Hamilton County Regional Planning Agency, green|spaces, The Lyndhurst Foundation, River City Company and Hamilton County Water Quality Program. 

Over the last year, the City of Chattanooga developed new runoff reduction standards for development and redevelopment sites.  The goal of this design challenge is to accelerate the adoption of LID and green infrastructure practices as the preferred method of managing stormwater, and complying with the new standards.  

Green infrastructure is a suite of options for the developer and design professional’s toolbox. It has been proven to provide benefits in water quality, natural habitat and flood control, reduce long term maintenance costs of stormwater management, increase the quality of life and livability of communities, and can potentially lower the cost of development. This competition will advance innovative, cost-effective, sustainable site designs that can serve as inspiring, regional models for watershed protection and community revitalization.
