Stormwater Management

MMI is committed to developing cost-effective, environmentally sensitive and resilient site-based stormwater management solutions, and has extensive technical experience in providing conceptual and detailed stormwater management plans for a vast range of urban infrastructure projects within the Greater New Orleans area as well as across the Gulf Coast. We incorporate a multiple objective approach into all stormwater management systems that we design, considering issues such as ecosystem health outcomes, flooding and drainage control, public safety, economic, social and aesthetic values.

Our technical experience in stormwater management is extensive and covers urban drainage design, hydrological and hydraulic software modeling, hydraulic impact/flood hazard and risk assessments, stream realignments and temporary diversions, scour and erosion protection of channels, culverts and bridges, and sediment/spill capture basin design.

We have a strong relationship with key stormwater management stakeholders within the Greater New Orleans area including the City of New Orleans, Sewerage & Water Board (S&WB) and the Louisiana Department of Transportation and Development (LADOTD) and a good understanding of their specific legislative and design requirements. We have also developed numerous site-based stormwater management plans to address the newly incorporated 1.25" of runoff stormwater management requirement included in Article 23 of the City of New Orleans Comprehensive Zoning Ordinance (CZO).
