Stormwater control continues to be a priority in many urban areas, with ever increasing flooding and water quality problems. When a metro community of MN, Inver Grove Heights, was facing development obstacles due to no natural drainage outlet, creative new methods were sought to solve this major obstacle to development. The innovative approach led to a zero discharge management system for the newly expanding portion of town. The new system led to many accolades for the city, including state, national, and international awards. What served as the foundation for this was a set of unique policies and ordinances that enabled this system to work with an unconventional approach. Policies and standards were developed for density flexibility, clustering, open space, parking, street widths, and runoff calculations that all became part of an overlay district ordinance. Hear how these standards served to preserve the development potential in an affordable way, while also preserving landscape character, reducing regional infrastructure costs, improving environmental outcomes, and reducing flood risks over conventional systems. While it almost sounds too good to be true, this unique approach brought together modern land planning concepts with new stormwater approaches to create a win-win solution for the community. Key findings include:
1. Planning/land use concepts can build better communities by combining stormwater requirements with environmental benefits and community-building.
2. Synergies exist between modern stormwater controls and flexible land planning can benefit each other in efficient and creative ways.
