Stormwater Management

HW is widely recognized as one of the most experienced stormwater management design, assessment, planning, policy, and training consultants in New England. Our philosophy is to mimic the natural hydrologic water balance as we design systems that are easy to construct and maintain. Our designs seek to enhance property values and improve aesthetic appeal using natural systems to meet stormwater management objectives and regulatory requirements. We have been developing and promoting innovative stormwater management tools and techniques since our inception in 1988.

Our stormwater designs have been implemented to meet a wide variety of objectives, including pollutant load reduction, wetland protection, habitat restoration, and groundwater protection. Our experience assisting local governments with siting, design, construction, and management of stormwater practices has earned us the opportunity to re-write state level regulations and develop stormwater design manuals and/or Low Impact Development (LID) guidelines nationally and in the Pacific Islands.
