Stormwater that dirty, oily runoff from streets and parking lots that contaminates local streams is a leading cause of water pollution in Ohio and around the country. American Rivers and Midwest Environmental Advocates released a report, “Local Water Policy Innovation: A Road Map for Community Based Stormwater Solutions” to help citizens tackle this pervasive problem and ensure clean water in their communities.
The threats posed by stormwater are caused locally, seen locally, and are best addressed locally. Stormwater pollution begins when natural landscapes are altered, changing the way water moves over the land. Hard structures such as parking lots and rooftops prevent water from naturally soaking into the ground. The rain water picks up pollution from streets and runs off into local streams. A typical 10-acre parking lot will create 270,000 gallons of polluted stormwater runoff after only one inch of rain. Our paved surfaces and rooftops generate 16-times more runoff than the fields they replace, increasing the frequency and severity of flash flooding. Due to sprawling impervious surfaces, many urban areas now lose between 300 and 690 billion gallons of water annually that would otherwise be filtered back into groundwater and drinking water supplies.
This report explains how to improve stormwater policies in local communities and capture the attention of policy makers. Local governments already have the processes in place to ensure good stormwater practices with zoning districts, site plan reviews, zoning ordinances, and Comprehensive Plans now it’s time to act.
By following the steps and guidelines in this report, citizens will be on their way to reducing stormwater pollution and making lasting changes in policy that preserve the natural landscape so many enjoy in local parks and at local waterways.
