West Whiteland Township’s Planning Commission is reviewing a conditional use application from Willow Hill Development Group to redevelop the 53.5‑acre former Weston Solutions office campus at 1400 Weston Way into 49 single‑family homes plus a lot for the historic Morstein mansion, which will be adapted into six apartments, with roughly 3,000 feet of new roads and more than 21 acres of open space. Multiple technical reviews (stormwater, traffic, historic resources, landscaping, sewer, fire protection, pipelines) are underway, and staff indicates all conditional use criteria are nearly met except for documented traffic impacts and final resolution of the sanitary sewer approach; roads will remain private and the sewer system will be owned/managed by residents or an HOA rather than the Township. This is still in the entitlement and design-feasibility phase: no land development plan or construction contracts have been awarded, and additional traffic data, detailed sewer design, pedestrian facilities, tree mitigation, and historic-preservation treatments must be finalized during land development.

Key technical issues still open include traffic/trip generation documentation, sanitary sewer strate...
