Low-Impact Stormwater Design


The firm designed low-impact stormwater management features for a proposed residential project with the aim of providing some level of water treatment through filtration as well as minimizing peak flow discharges by the application of infiltration. This approach not only resulted in a significant reduction of the size of stormwater detention structures, which in turn produce an economy in construction cost, but also provides better quality stormwater discharges to adjacent mangrove forests. Techniques included the diversion of drainage onto grassed areas and shallow depressions, instead to routing stormwater directly to pipes, increasing the travel time and in turn reducing the peak discharge of the site. The project also include the design of the storm water detention structure ant its components.
