HRGM Corporation has built parks, playgrounds, and green spaces throughout the Washington metropolitan area for over 2 decades. We can perform work on a design-build and design-assist, and we regularly contract as a general contractor or construction manager. Many of our parks feature innovative low impact development measures, including bioretention, infiltration and exfiltration structures, and permeable paving, which help reduce runoff and storm surges. We install green features like LED lighting and green roofs, as well as fun features like motion-activated spray parks and custom play equipment. Our parks provide safe, healthy, and active recreation opportunities for children, neighborhoods, and communities.
