Synterra, Ltd. provided landscape, open space and master planning consulting services for the redevelopment of five hundred and twenty-two (522) acres on the east side of the Philadelphia Navy Yard.

The site was defined by four districts; Gateway, Historic Core, Marina and East End. Synterra, Ltd. developed an open space system that includes new parks, streetscapes, plazas, trails, and existing green spaces in the Historic Core, recreational facilities, landscape areas and natural areas. The open space system included parks of different sizes, programs and purposes.

The open space plan unified the different areas of the site making effective connections, establishing places for people and restoring the natural system of the site. The open space master-plan changed the character of the Navy Yard from an industrial site to a more people oriented community.
