Rainfall patterns and intensities have been ever-changing in recent years, and our staff have firsthand knowledge of these effects. raSmith is a trusted advisor to our public and private sector clients. We have applied our knowledge and capabilities in the stormwater industry to analyze areas and provide creative solutions to effectively manage stormwater runoff. Our team has vast experience in designing stormwater infrastructure and best management practices for water quality and water quantity benefits. Our stormwater management design expertise is applied to land development and redevelopment projects (commercial, residential, roadways, and parks) as well as transportation systems and municipal TIF developments, including the preparation of master stormwater management plans. Our clients’ stormwater needs are met with innovative approaches and designs based on a thorough understanding of hydrology, hydraulics, and ecological systems. We face regulatory requirements with careful attention honed by years of successful stormwater solutions. Our water resources and stormwater engineers develop sustainable solutions for landowners, municipalities, county agencies, sewerage districts, consulting firms, private businesses, and developers.

Planning
Our stormwater planning services lay the foundation for resilient and sustainable communities. From comprehensive watershed master plans to targeted drainage studies, we help municipalities and developers anticipate and manage water flow challenges. We support MS4 permit compliance with detailed annual reports, and guide clients through user fee feasibility analyses and stormwater utility creation, ensuring financial sustainability. Our team excels in TMDL planning and implementation, securing cleaner waterways, and we streamline grant preparation and administration to unlock funding opportunities. With thorough site assessments and SWPPP development, we help clients mitigate pollution risks and meet regulatory standards.
Modeling and Mapping
Precision is key in stormwater management, and our advanced hydrologic and hydraulic modeling delivers just that. Whether it’s culvert sizing, floodplain mapping, or neighborhood drainage analysis, our data-driven approach ensures accurate, actionable insights. We also specialize in pollutant loading analysis, helping clients understand and reduce environmental impacts. Our cutting-edge drone mapping capabilities provide high-resolution visuals and topographic data, enhancing project planning and execution.
Streambanks, Wetlands, and Permitting
Protecting natural resources is central to our mission. We offer expert streambank stabilization and erosion evaluations to preserve infrastructure and ecosystems. Our in-stream restoration and habitat improvements enhance waterway health and biodiversity. With comprehensive wetland screening and delineations, we help clients navigate complex environmental regulations. Our team also manages waterway and floodplain permitting, ensuring projects move forward smoothly and compliantly.
Inspections
Our inspection services provide peace of mind and regulatory confidence. We conduct thorough illicit discharge inspections and erosion control planning, safeguarding water quality and site integrity. Our drainage investigations and BMP audits identify issues early, saving time and resources. We also perform bathymetric surveys and develop dredging plans to maintain waterway functionality. With drone inspections and detailed documentation for regulatory audits, we deliver transparency and accountability every step of the way.
