Water Resources

Neel-Schaffer is recognized for expertise in all aspects of water resources engineering, including floodplain management, riverine and coastal hydrologic/hydraulic modeling, flood control structure analysis/design, cross drain/bridge hydraulic analysis and design, storm sewer system modeling and calculations, and complex design of municipal storm water infrastructure for drainage improvement and flood reduction projects.

The firm maintains solid, long-standing relationships with many Southeastern cities and communities, including serving as City Engineer and/or Floodplain Manager for multiple cities.  Neel-Schaffer has 11 Certified Floodplain Managers on staff in its Southeastern offices, and each has extensive experience navigating the waters of FEMA compliance, flood damage remediation/mitigation, floodplain permitting, flood hazard mitigation grant applications, floodplain ordinance development, and all aspects of local floodplain program management.  The staff also has extensive experience initiating storm water utilities (i.e. user fees) in communities with enabling legislation, developing and implementing Storm Water Programs, assisting cities with NPDES Municipal Separate Storm Sewer System (MS4) Permit compliance, and providing expert testimony (see also Storm Water Management).

Neel-Schaffer’s expert engineering team works to plan, model, and design a variety of storm water and flood control structures for water resource projects, employing the disciplines of hydrology, hydraulics, civil, geotechnical, and structural engineering.  We keep complex projects on schedule and within budget, while ensuring local design and aesthetic requirements, as well as environmental requirements, are met.
