Ohio’s urban areas have continued to grow, leading to a significant increase in impervious surfaces—such as roads, parking lots, and buildings—that prevent natural water infiltration. This expansion exacerbates stormwater runoff, overwhelming existing drainage systems and elevating flood risks. The U.S. Environmental Protection Agency (EPA) has developed tools like the Impervious Surface Growth Model to help communities estimate and manage the impacts of such developments.
1. Increased Flooding Due to Impervious Surfaces
The proliferation of impervious surfaces accelerates stormwater accumulation, leading to flash flooding during heavy rain events. Cities like Columbus have recognized these challenges and are adopting innovative approaches. For instance, Blueprint Columbus integrates green infrastructure to address sewer overflows and improve water quality, moving beyond traditional gray infrastructure solutions.
2. Aging Stormwater Infrastructure and Inadequate Detention Systems
Much of Ohio’s stormwater infrastructure is outdated, with systems dating back several decades. Older reinforced concrete storm drains and outlet pipes struggle to handle modern stormwater volumes. Municipalities are now incorporating underground detention systems and precast concrete detention tanks to enhance stormwater storage and controlled water release.
3. Water Contamination and Environmental Consequences
Urban stormwater runoff carries pollutants such as oil, heavy metals, and sediment into Ohio’s waterways. The Ohio River and Lake Erie watersheds have experienced increased contamination due to inadequate stormwater management systems. To address this, cities are implementing erosion control products, stormwater detention systems, and pond outlet structures to slow runoff, filter contaminants, and improve overall water quality.
4. Challenges in Managing Stormwater from New Developments
New developments must comply with stringent stormwater regulations, yet many projects struggle with designing effective stormwater retention solutions. Ohio’s Smart Growth Program emphasizes integrating detention tanks, stormwater detention systems, and pond outlet structures into development plans to mitigate urban runoff issues. However, improper installation or undersized outlet control structures can lead to long-term drainage failures and increased maintenance costs.
5. Future Projects and Regulatory Compliance in Ohio
Ohio’s municipalities are actively working on stormwater infrastructure improvements to comply with U.S. EPA regulations and state mandates. Initiatives like Blueprint Columbus aim to reduce combined sewer overflows by integrating green and gray infrastructure, including stormwater detention tanks and underground detention systems.
