Cornerstone Master Plan Development

The former gravel mine that had become an excess corporate real estate asset was morphed into 225-acre mixed use, commercial development. In the role of Master Developer, Griffin’s key elements of this engagement entailed land assembly and acquisition, right-of-way negotiation, utility and infrastructure development, and public outreach.

One key public facility component of the development is Cornerstone Park. The project’s scope included program management of the design by the architect PDG and construction management of the park that included a 19-acre lake, four acres of non-parking, and a non-slope area with 22 acres of useable land open space. Adjacent parking for 470 vehicles and oversized buses were provided outside the 100-year flood elevation. The lake provides 3,600 linear feet of shoreline, and 370 linear feet of waterfront dock with two separate overlook areas.

The $60 million infrastructure development that involved oversight by Griffin included roads; streets; traffic signals; dry utilities; pedestrian walkways; landscaping; rough grading; new and relocation of utilities consisting of water, sewer, and storm drains; stormwater culverts; and a detention basin.

Griffin also structured, managed and implemented a series of community outreach programs in order to determine potential user preferences on park components, culminating in a definitive plan for the project, which was well received. In this process, we also engage neighboring homeowners' associations to discover and ascertain their concerns and to seek their input on opportunities.
