Natural Infrastructure Plan Incorporates Future Risks

Over the past four decades, the Chagrin River watershed near Cleveland, Ohio, has experienced double-digit increases in heavy-precipitation days and the amount of rain falling on those days. Several studies predict more frequent and severe events over the next 50 to 70 years.

After studying the issue, the Chagrin River Watershed Partners and Ohio Sea Grant recommended stormwater-code updates that are being considered by local officials. These include stricter riverine setbacks in flood-prone areas and updated designs allowing today’s bioretention ponds and permeable pavement to keep up with future stormwater increases. The partners also trained engineers, planners, and floodplain managers on techniques for installing and adding natural infrastructure. The NOAA Coastal Storms Program helped fund this project.
