Stormwater management facilities are designed to provide a controlled release of stormwater to downstream areas following storm events. There are many different types of stormwater designs, such as wet and dry ponds, bioretention ponds, infiltration basins and rain gardens. These systems require varying degrees of maintenance over time in order to continue functioning as designed. The methods of construction are essential to their effective performance. CGC Geoservices has experience with the construction and maintenance of several different types of stormwater features including sand filters, rain gardens and infiltration basins.
