Stormwater Management Design


Our expertise in all aspects of stormwater management includes planning, modeling, design, and construction plans and specifications.  In a time when environmental design is in constant evolution, our engineers work closely with regulators for a better understanding of current practices and stormwater management techniques.  With Maryland’s proximity to the Chesapeake Bay and a host of other natural resources, it is ever important that our designs maximize water quality potential for each site while maintaining an eye for cost-effective and resource-efficient solutions.


CDG designers are experienced in providing creative design solutions that implement MDE’s Environmental Site Design practices to the Maximum Extent Practicable.  With a goal of maintaining pre-development runoff conditions after development, we utilize ESD planning techniques and treatment practices that eliminate or minimize the need for structural BMPs.


With no shortage of aging SWM facilities designed under outdated design standards in our region, CDG can provide solutions.  Our team can provide inspection and remediation recommendations for existing BMPs, as well as performance analysis and retrofit design for BMP upgrades.
