Baton Rouge, Thibodaux, Covington, New Orleans, Lafayette, LA; Gautier, MS; Mobile, AL; Houston, TX
In 1997, DDG began as a small, civil engineering firm based in Thibodaux, Louisiana. Since founding, their unwavering commitment to client service excellence has allowed them to grow into a multi-disciplinary regional firm providing landscape architecture, coastal engineering, water resources engineering, architecture, environmental and regulatory consulting, surveying, transportation engineering, funding advisory, structural engineering, and project management with eight offices across the Gulf Coast. DDG's landscape architecture group is well known for the planning and design of inspired landscapes that reflect the ecology and culture of places throughout the Gulf South. Their extensive experience in the park and recreation arena leads to an understanding of not only the planning and development side, but also the perspective of the public agency responsible for maintenance and management of the facility. Regardless of the client or project scope, DDG is committed to developing aesthetically pleasing, functional design that lays a strong foundation for the future of any site.

Port Fourchon Recreational and Wetlands Park; Port Fourchon, LA
Port Fourchon is a strategic petroleum seaport that supplies about 18% of the entire U.S. oil supply. Due to a vital expansion, a new saltwater marsh was created to mitigate impacted coastal marsh. DDG created a master plan for a 43-acre coastal wetlands park within the mitigation site.
