Managing stormwater is an important consideration for industry, municipalities, and real estate developers. Seneca Engineering provides design services for cost effective stormwater erosion and sediment control facilities for new construction and existing facilities. We also provide regulatory assistance with meeting federal, state and local stormwater regulations.
Individual and General NPDES permits may require you to comply with permit terms and conditions along with numerical limits for the discharge of stormwater. The Seneca Engineering Team includes personnel with decades of experience in interpreting and identifying regulations that apply to your situation and cost-effective engineering design solutions. Our team includes a retired former 30-year Ohio EPA, Division of Surface Water employee with over 6 years of consulting experience. This regulatory experience supplements our core engineering capabilities to design for many unique stormwater management system challenges.
