Storm Drainage Design

Advanced Storm Drainage Design for Resilient Infrastructure

RSP Engineers delivers sophisticated storm drainage design solutions to protect properties, communities, and the environment from the challenges of excess water. We engineer innovative and efficient stormwater management systems that prevent flooding, ensure regulatory compliance, and promote sustainable water practices. From master planning to detailed design, we create systems built to withstand the elements.

Our Stormwater Management & Design Expertise

Effective stormwater management is more than a regulatory requirement—it's a critical component of responsible Engineering Land Development. We design customized drainage systems that are both effective and cost-efficient, addressing the unique hydrological conditions of each site.

Our Comprehensive Drainage Engineering Services

Our services encompass all facets of stormwater conveyance, storage, and treatment. Our capabilities include the following:

- We use state-of-the-art software to accurately model rainfall, runoff, and water flow, ensuring our designs can handle storm events of any magnitude.
- Engineering networks of pipes, inlets, and culverts to efficiently collect and convey stormwater away from critical areas.
- Designing basins and other storage facilities to manage peak flows and prevent downstream erosion and flooding.
- RSP Engineers provides expert floodplain analysis and mitigation services to help clients navigate regulatory requirements and reduce flood risks. Our team conducts detailed hydrologic and hydraulic studies to assess floodplain impacts and designs mitigation strategies—such as compensatory storage, grading adjustments, and drainage improvements—to ensure compliance with FEMA, local, and state regulations. We help secure approvals and permits, supporting safe and resilient site development.
- Designing effective dry and wet retention areas that meet storage and water quality requirements while providing usable green space
- Engineering underground systems that promote groundwater recharge while managing runoff volumes in space-constrained sites.

Stormwater Quality and Treatment

Meeting water quality standards is paramount. We design systems that effectively remove pollutants from stormwater runoff before it enters natural waterways.

Best Management Practices (BMPs)
Implementing proven BMPs and Low-Impact Development (LID) strategies to filter and treat stormwater.

Stormwater Drainage Recertifications
We manage the inspection and recertification process for existing stormwater systems as required by many Florida municipalities, ensuring ongoing compliance.

Permitting for Storm Drainage Systems

Our team has extensive experience securing stormwater-related permits from local, state, and federal agencies. We manage the complex application and review process to keep your project on track.

- Obtaining permits from water management districts such as the South Florida Water Management District (SFWMD) and the Central Broward Water Control District.
- We handle National Pollutant Discharge Elimination System (NPDES) permit applications for construction activities, a process we also manage through our dedicated NPDES Inspections service.
- Securing approvals from departments of transportation (e.g., FDOT) and local public works agencies for connections to public drainage systems.
RSP Engineers specializes in preparing and securing Stormwater Environmental Resource Permits (ERP) for projects across the US. Our team designs effective stormwater management systems—such as retention ponds, exfiltration trenches, and treatment swales—to meet water quality and quantity requirements. We handle the full permitting process with water management districts and local agencies, ensuring timely approvals and regulatory compliance for both new developments and redevelopment projects.
