Low Impact Development & Bioretention

Low Impact Development (LID) is an innovative approach to stormwater management involving site design that duplicates the hydrologic features of an undeveloped watershed. This relatively new approach to stormwater management is an increasingly more popular way of preserving water within it's natural watershed and protecting valuable groundwater resources.

WHAT's NEW in LID?

Norfolk awarded 2006 Smart Growth Award

Norfolk Ram Group, LLC and the Town of Cohasset, MA have been awarded a 2006 Smart Growth award by the Commonweatlh of Massachusetts.

Low Impact Development Presentation availble for download at the Charles River Watershed Associations's Website. Michael F. Clark, P.E., presented "LID in Practice:Engaging the Community.  The Cohasset Retrofit Project" at the CWRA's Stormwater Sessions Workshop on June 21, 2006.

Instead of conveying, managing and treating stormwater in large, costly facilities located at the bottom of drainage areas, and often outside of the natural watershed, LID simulates natural hydrologic cycles by addressing stormwater through small, cost-effective landscape features located at the lot level. These landscape features, known as Integrated Management Practices (IMPs), can be distributed throughout a developed site to mitigate the impact of development. IMPs minimize impervious surfaces, create on-site storage, maximize opportunities for infiltration, slow down the flow of surface run-off, detain, and/or retain water, and remove pollutants. IMPs can also be incorporated into existing developments utilizing retrofit design.

Bio-retention presents a low-cost and low-maintenance technique to improve stormwater quality (beyond that which is obtained by implementing the Massachusetts Stormwater Policy) and stormwater impacts to wetland resource areas. Bio-retention facilities consisting of engineered soils will capture litter, debris

and suspended solids, and the soil plant matrix will treat stormwater as it passes through, capturing a significant amount of pollutants. Treated runoff is then infiltrated and/or collected in traditional stormwater collection systems. Norfolk Ram Group is an engineering leader in Massachusetts in implementing improvement projects involving Low Impact Development (LID) and retro-fit designs (LID / BMP design) for developed/urbanized areas, including stormwater monitoring, permitting, and construction administration.  Norfolk Ram is one of the few firms in Massachusetts with extensive expertise in LID design and construction and is an active member in the Ecological Landscaping Association
