Griffin is serving as construction manager for several projects for The Trust for Public Land (TPL). A national non-profit organization founded in 1972, TPL and its Parks for People Program work with communities to protect and create close-to-home parks—particularly in and near cities, where 80 percent of Americans live. TPL works toward ensuring that every child has easy access to a safe place to play in nature and sets a goal of putting a park or open space within a 10-minute walk. In the City of Los Angeles alone, more than 1.5 million residents do not have a park within a 10-minute walk from their homes.

TPL engages residents in park planning to identify specific community recreational needs. Each project is unique in that it provides a mixture of passive and active spaces with designs influenced through community input. Community members often participate in planting and creating iconic, colorful mosaics. Parks are designed to be ecologically sensitive and minimize maintenance costs.

Griffin Structures is providing program and construction management services including assistance in contractor selection, constructability review, budget tracking, schedule review, and construction management including field observation, project meetings and progress payment review. To-date, seven parks and the Avalon Green Alley Network are complete; three additional parks and two green alley projects are in the planning or early construction stages.
