GRA has been involved in land development projects since the firm's inception. Over the years, we have gained wide and comprehensive experience in the site development process and issues. GRA provides services to clients in the engineering and related disciplines listed below on residential, commercial and industrial site development projects.

We invite you to view the representative projects below. Simply click on the project name to view a photograph or graphic and a brief project description.

Mount Hope Boat Ramp

Bristol, Rhode Island
Owner: Rhode Island Department of Environmental Management

This project required the design of a new 60-foot-wide boat ramp with two floating courtesy docks, one of which is fully-handicapped accessible; a three-tiered parking area; approximately 1,000 feet of access road to enter the site; a Gazebo; and bio-retention for water quality. There were several wetland areas throughout the site that impacted the design and layout of the facility. GRA developed a stormwater management plan to improve the quality of the runoff to the Narragansett Bay. The system included bio-detention areas and overland flow to control and mitigate pollutants. In addition, GRA collected sediment samples from the boat ramp/dock areas and used the analytical data to evaluate dredge spoils management options. Metals identified in the sediment met the Residential Direct Exposure Criteria but were not compliant with the beach nourishment criteria. A dredge spoils management plan was developed in accordance with the RIDEM's Rules and Regulations for Dredging and the Management of Dredged Material. The plan allowed the project to dredge materials from the bay, re-utilize the dredge spoils as part of the new parking facility's sub-base, and cap the placed spoils with gravel and asphalt to prevent stormwater infiltration.

I-295 Northbound Rest Area and Blackstone Valley Gateway Center

Lincoln, Rhode Island
Owners: Rhode Island Department of Transportation and the Rhode Island Departments of Environmental Management

Through a cooperative effort between the Rhode Island Department of Transportation (RIDOT) and the Rhode Island Department of Environmental Management (RIDEM), the Interstate Route 295 (I-295) northbound rest area was completely redesigned. The reconstructed site, which includes the Blackstone Valley Gateway Center, serves as an intermodal "gateway" to the neighboring Blackstone River Linear Park and Bikeway. The site design included entrance and exit ramps, access roads, parking facilities, sidewalks, landscaping and storm water management. The site contains tourist, park and bikeway amenities for the public. The parking area serves a variety of vehicles including tractor-trailers, campers, buses and automobiles.

As the lead civil engineer for the project, GRA's services included developing the master plan, assisting the client through a rigorous zoning process, preparing comprehensive environmental applications for both RIDEM Freshwater Wetlands and RI Coastal Resources Management Council, preparing subdivision plans and conducting final design. The final design efforts included the preparation of complete construction plans for roads, sewer system, sewage pumping station, and storm drainage and water distribution systems, and included coordination with other public utilities such as gas, telephone, cable TV and fire alarm. GRA was successful in securing final approval of the master plan and all environmental permits for the owner.
