Miami Valley Storm Water

MVRPC has been building our efforts to assist jurisdictions that hold Municipal Separate Storm Sewer System (MS4) general permits from Ohio EPA. The storm water program applies to communities within the census-defined urbanized areas of Ohio, including over 40 communities in the Miami Valley. The purpose of the program is to reduce the pollution carried in run-off water into Ohio’s rivers, streams and lakes.

Past MVRPC Storm Water Efforts

Northwest Montgomery County Storm Water Seminar
October 31, 2016

The expansion of the Dayton Urbanized Area after the 2010 Census brought four new communities under the Ohio Storm Water Program as new MS4 Communities: Brookville, Clay Township, Perry Township and Phillipsburg. MVRPC coordinated and hosted a workshop for these four communities to kick start their thinking about how to meet the requirements. Speakers from Ohio EPA Central Office and Southwest District Office, as well as the Butler County Storm Water District provided representatives of the communities valuable information about the program requirements. The session prompted good questions and intra-jurisdictional discussions about how to move forward. The City of Brookville kindly hosted the session in their council chambers.

Storm Water coverage mapping

The update to the census-defined urbanized area expanded (or at least changed) the coverage area of the Storm Water program for several jurisdictions, particularly those on the developing edges of the Region. MVRPC provided maps or GIS data for those communities to assist their planning for managing storm water in new parts of their communities.
