Mainline Health presents revised plans for proposed Coatesville medical campus; board delays decision to November

Ryan Jennings, representing Mainline Health, told the Caln Township Board of Commissioners that the developer has revised its land‑development plans after multiple Planning Commission reviews and consultant comments and is aiming for final plan approval at the board’s November meeting. "We have managed to accommodate each and every ask that the township staff and the township consultants and planning commissioners have made along the way," Jennings said.

Lindsey Breilinger, the project civil engineer, described several substantive plan changes since the spring filing: the parking lot access was relocated to a central drive aisle; a single stormwater basin was split into two and an additional basin was added south of the Geo Carlson extension; curbing will be installed on both sides of the Geo Carlson extension; and landscaping was expanded along Lloyd Avenue and around basin areas to create evergreen buffers. The plan also shows a decorative fence and brick piers along Manor Avenue and decorative street lighting along the Geo Carlson extension and Manor Avenue.

Staff and the applicant said they intend to comply with the 21 conditions the board imposed when it granted conditional use approval on June 12, 2025, and noted the Planning Commission unanimously recommended approval of the revised plans and the 11 requested waivers. Jennings said the team has filed preliminary/final plans and has submitted applications that will be routed to PennDOT (highway occupancy permit) and PENNDOT traffic/permitting processes for the proposed signal and approach work.

Commissioners and residents pressed the project team on pedestrian and bicycle access, transit access, and easements. Several commissioners urged addition of a bike lane along the Geo Carlson extension and a sidewalk connection from the development into existing pedestrian routes; one commissioner called for the developer to pursue a SEPTA bus stop or at least a recorded easement so the municipality could build a future bus pad. Township staff and the applicant said they will continue discussions with SEPTA and attempt to secure easements from neighboring property owners for stormwater and pedestrian connections; staff also recommended a post‑development traffic study to verify trip generation and to review signal timing along Manor Avenue after the facility opens.

Project timing cited by the applicant includes a projected facility opening in 2027 with full occupancy processes continuing toward 2031; the applicant agreed to the post‑development counts once an occupancy threshold is agreed with township staff. No formal vote was taken at the meeting. The applicant told the board it expects to return for final land‑development approval at the board’s November 13 public meeting.
