Planning commission raises concerns about data center siting, water use and loss of manufactured‑housing stock
Loading...
Summary
Commissioners spent a significant portion of the meeting discussing the rapid growth of data center proposals, focusing on energy and water needs, farmland loss and an example of a manufactured‑housing community sold for a data‑center project. The discussion emphasized zoning limits, municipal tools and potential regional outreach or training.
At its Nov. 3 meeting the Dauphin County Planning Commission devoted substantial discussion to regional data center siting and the land‑use and housing pressures associated with that growth.
Commission members described multiple municipal meetings in which communities are wrestling with where and how data centers should locate. Staff and commissioners noted data centers have large energy and water demands and tend to require large parcels of land, leading to concerns about conversion of farmland and loss of lower‑cost housing sites such as manufactured‑housing parks. Gary Lenker said one community in northeastern Pennsylvania recently sold a manufactured‑housing park of more than 100 sites to a buyer planning a data center, underscoring the potential for displacement.
Speakers emphasized that while data centers generate relatively little local traffic and do provide tax revenue, their utilities and siting footprints present planning tradeoffs. Commissioners discussed the limited local levers available — zoning, local ordinances, and incentives — and noted the commission’s primary tools are technical assistance, plan review comments, and conditioning county funding support on plan consistency with regional goals.
Commission members and staff proposed outreach options to address the issue at a regional scale, including municipal training, a possible regional housing summit, and using the Local Planning Assistance (LPA) program to work directly with municipalities on ordinance updates. The discussion linked these local concerns to broader housing policy work: staff referenced recent federal housing legislation (the Road to Housing Act) as another impetus for zoning and land‑use review.
No formal action or ordinance change occurred during the Nov. 3 meeting; commissioners said further engagement and technical assistance would be considered as the county updates its comprehensive plan and conducts outreach.
