Stormwater Systems

Storm drainage and stormwater management is a critical aspect of site engineering and facility management in today’s environmentally conscious climate. EA’s unique blend of experienced scientists and engineers enable us to provide full stormwater management services from site evaluation and stormwater modeling through facility design and permitting to construction management and long-term monitoring. Our approach ensures that mandatory performance criteria are met and the stormwater management facilities and storm drain structures are the most effective, cost-efficient, and maintenance-conscious options, while conforming to existing site restrictions and features. EA has compiled a significant track record of successfully completed projects in the execution and management of water quality and quantity management projects—achieving clients’ objectives related to local stormwater management needs and permit-driven water quality improvement needs—and completing projects on schedule and within budget.

EA has an outstanding reputation for technical expertise in stormwater management design, responsive service, and judicious use of client resources based on our 45-year history. Our staff offers a well-rounded team of professionals with a broad range of not only storm drainage and stormwater management expertise, but also a depth of regulatory and environmental compliance experience, permit negotiation and consent order support, ecology and toxicology evaluation, extensive knowledge of state and municipal planning processes, and a strong understanding of the relationships between public entities that support project teams and funding that require shared resources. EA has proven working relationships with the local and State regulators, local Soil Conservation Districts and Natural Resources Conservation Service professionals, and other project stakeholders integral to executing stormwater management projects.

Listed below are just some of the Stormwater Management design services we perform regularly:

  • Closed and open system drainage infrastructure
  • Stormwater Management best management practices (BMPs)
