The full picture AI research · Nov 1, 2026
The Preserve at Stony Creek would turn about 67 acres of the former Norristown State Hospital grounds into a mixed-use neighborhood. County records list 682 new homes, mostly townhouses and apartments with shops on the ground floor, in the western part. They also list about 303,000 square feet of retail and office space. The eastern part would hold office and technology buildings in an industrial style.
The land is part of a state hospital campus that still operates on a smaller footprint. The plan requires demolishing one building and removing 475 mature trees.
News coverage from 2024 and 2025 described earlier versions with more than 700 homes, a grocery store, a public gathering space and a tech campus. The developer was chosen through a competitive process. Residents raised worries about density, traffic and schools. Coverage from early 2025 said construction could finish by 2032. No tenants were named.
What it could mean nearby
- Traffic and school capacity were the main concerns residents raised in news coverage; no traffic study was found.
- Several hundred new homes, at townhouse and apartment price points, would add to the local housing supply.
- Retail, a possible grocery store, and office or tech space could create local shopping options and jobs.
- Removing 475 mature trees would reduce tree cover on the site, though earlier coverage said some open space and walkable streets are planned.
Where it stands
The county filing dated 2026-06-26 shows the plan in government review. No final approval was found online. Next steps usually include county planning review, then municipal planning and council votes on land development plans, followed by state and local permits.
