The Lyon’s Business Park is a 340,000 SF Light Industrial Park situated on 38.1 acres in Miami Township, Montgomery County, OH. The project was the lower portion of a 147 acre watershed with the upper 109 acres being 72% developed with impervious surfaces and on uncontrolled storm water systems. The challenge was how to create a 500 foot stream mitigation program through the site that would satisfy the development needs as well as EPA’s requirements.
