Low impact development treatment train tool
The Low Impact Development Treatment Train Tool (LID TTT) is designed to help developers, consultants, municipalities and landowners understand and implement more sustainable stormwater management planning and design practices in their watersheds.
The LID TTT focuses on the use of Low Impact Development best management practices (BMPs) to meet stormwater management criteria for the site and can be used to:
- analyze annual and event based runoff volumes,
- provide estimates of water quality improvements.
The LID TTT is built upon the open source EPA SWMM5 hydrologic model providing a user-friendly interface for novice modelers and cross-compatibility with SWMM5 for further model development.
Integration with this guide is through suggested 'starting point' values for design parameters for the following BMP types:
- Vegetated filter strips
- Infiltration trenches
- Permeable pavements
- Rainwater harvesting
- Dry ponds
- OGS and filters
