Walnut Grove is a ±129-acre master-planned community taking shape along Walnut Bottom Road in South Middleton Township, just outside Carlisle in Cumberland County, Pennsylvania. The plan brings a town-center feel to the property: a walkable commercial center of roughly 51,000 square feet fronting Walnut Bottom Road, wrapped by fee-simple townhomes and condominiums, with larger single-family homes toward the rear of the site and an athletic field proffered for public use. In all, the master plan calls for approximately 638 residential units.
Location & Market. The site is in South Middleton Township, just outside Carlisle in Cumberland County — one of the fastest-growing areas in central Pennsylvania. Carlisle's population is up more than 15% since 2020 (now about 23,300), and the county is approaching 271,000 residents. Carlisle is a nationally significant logistics and distribution hub at the crossroads of I-81, the Pennsylvania Turnpike (I-76), and U.S. 11, with a diverse economy spanning manufacturing, healthcare, and education and roughly 12,000 jobs in the town itself.
Access & Connectivity. The property sits about 18 miles west of Harrisburg with quick access to I-81, the Pennsylvania Turnpike, and U.S. 11 — placing it within a day's drive of much of the Northeast and Mid-Atlantic.
Development Potential. Walnut Grove's town-center master plan — roughly 638 residential units plus commercial — is advancing through the township approval process in coordination with the local Board of Supervisors, with a public hearing anticipated this summer, in a supply-constrained, high-growth submarket with strong rooftop demand driven by the area's logistics and employment base.
