Stormwater Management

Any sort of construction, whether big or small, will disturb the flow of water in an area. Changing the amount of impervious surface on a lot or the land use can increase the chance of flooding or erosion on the parcel, or surrounding area. Stormwater runoff can not only be a risk for flooding and damaging property, but is also the single largest source of impairment to the water quality of our rivers, lakes, ponds, and coastal waters. Massachusetts has stormwater management standards which are in effect statewide, and the cities and towns each have different bylaws surrounding stormwater which our professionals are experts in.

This plan was designed for a Boston company building on Shetland Street in Roxbury. The plan shows the proposed and existing drainage along with other utilities. The proposed catch basins were placed with reference to the grade of the property to maximize their effectiveness. To reduce pollution, the large parking lot's catch basins all drain through the same pipe, which then flows through an oil/water separator before connecting with the main sewer line. In the smaller parking lot, the single catch basin is equipped with an oil tap. On the southwestern side of the property you will also see a Cultec Recharger installed to allow water to recharge into the soil and decreased the stormwater runoff of the property, and help to reduce the stormwater load that the city must handle.
