Lionville Preserve is a sketch plan for a planned community on about 254 acres in Uwchlan Township. County records list 269 single-family homes, 342 townhomes (611 in all) and a natatorium, which is an indoor swimming facility. The records count 74,000 square feet of non-residential space.
The site appears to be the Lionville Station Farm property near Exton. It is a former industrial campus owned by the Downingtown Area School District. A local news report describes a later version of a plan for this site. That version has 492 homes, mostly age-restricted, and the same natatorium. It would keep about 127.5 acres as open space. The report does not use the name "Lionville Preserve," so the match rests on the matching acreage and natatorium.
The developer has a contingent agreement to buy the land from the school district. A fallback industrial plan of about 1.8 million square feet is also pending under current zoning.
What it could mean nearby
- Traffic: the developer has reportedly agreed to pay for road improvements. It would pay for more work if traffic after construction is worse than projected.
- Open space: about 127.5 acres would be preserved, with about two miles of trails along Pickering Creek (492-home version).
- Schools and taxes: the developer's analysis projects a yearly surplus for the township and school district. This is the developer's own estimate.
- Amenities: a natatorium is proposed, but the operator has reportedly not committed to the site.
Where it stands
The county's latest filing is dated 2025-09-17 and covers a sketch plan, which is an early, informal review. News reports say the township supervisors closed the hearing record on the rezoning and conditional-use requests in September 2026. A decision is due within 60 days of that, and formal subdivision and land development plans would follow if the request is approved.
