Upper Macungie supervisors gave final land development approval Sept. 2 for Eli Lilly’s manufacturing facility in Fogelsville while also requiring traffic mitigation measures tied to a construction plan expected to support as many as 1,500 workers during peak construction.

The board of supervisors unanimously approved the Final Land Development Plan and Sewage Planning Module for the project after hearing details of a construction logistics plan designed to manage worker transportation and traffic impacts.

Bailey Occhipinti, director of entitlements and permitting for the Lilly Lehigh Valley Project, said peak construction is anticipated from the fourth quarter of 2027 through the first quarter of 2029. At that time, as many as 1,500 workers, including approximately 1,200 trade workers and 300 administrative staff members, could be working on the project.

The construction plan includes five site entrances and a shuttle bus system to transport workers from off-site parking areas. Lilly has secured 600 off-site parking spaces in the Tilghman Street area and identified additional parking in the surrounding Windsor office area. Occhipinti said the company also plans to install a traffic signal and widen Main Street in 2027 before peak construction begins.

Supervisors discussed the potential effect of construction traffic on Tilghman Street, Route 100 and surrounding roads. Vice Chairman Sunny Ghai questioned whether worker and construction traffic could be scheduled to minimize congestion during peak travel periods.

Occhipinti said the construction traffic study examined several intersections and was used to develop work shifts and transportation schedules.

As a condition of approval, the board required the construction traffic study to be incorporated into subsequent development documents, making its traffic mitigation provisions binding on the developer and requiring continued coordination with the township if problems arise.

In other business, supervisors approved the use of PA SITES funding for installation of a new sanitary sewer trunk line serving 7350 and 7356 Industrial Blvd., where Chobani plans to take over the former Keurig Dr Pepper facility.

Township Manager Robert Ibach said the state funding will be used for sewer improvements needed to accommodate Chobani’s increased wastewater flows in lieu of the township collecting allocation fees. At Ghai’s request, the motion was amended to cap the arrangement at an allocation of 800,000 gallons per day. If wastewater flow substantially and consistently exceeds that amount, Chobani could be required to purchase additional allocation. The amended motion passed unanimously.

The board also authorized readvertising for Community Lifestyle Center concession operations after no proposals were received by the Aug. 17 deadline.

Earlier in the meeting, Chairman Jeff Fleischaker welcomed newly appointed Supervisor Andrew “Andy” Snyder. Supervisors also elected Ghai vice chairman for the remainder of 2026, filling the vacancy created by former Vice Chairman Julien Godbarge’s departure.
