Borough staff presented a parcel‑level extract for the Franklin Square development and told council the York County Board of Assessment Appeals applied market‑value assumptions tied to the county’s 2004 reassessment when resolving a developer appeal. Staff said that approach produced a first‑year revenue loss for the borough’s general tax—for example, an assessed reduction of about $3,038,400 in one parcel line produced an estimated annual general‑fund loss of about $7,779 based on current millage.

Staff explained that York County’s last countywide reassessment occurred in 2004. The county board of assessment appeals uses available reassessment data and reassessment schedules when evaluating appeals; staff said the borough and county school district received notices but that the municipality’s appeal opportunity had lapsed in this case. Staff noted that interim increases in assessed value will occur only when building permits or substantial improvements are reported for specific parcels and that a countywide reassessment would be required to update valuations more broadly.

Council members asked for additional historical comparisons and asked staff to check assessed values in earlier tax duplicates (for example, 2022) to better understand timing and the dates when commercial parcels were placed on the duplicate. Staff said they will continue to monitor interim assessment change activity and noted that requesting a countywide reassessment would be a legislative and administrative decision at the county level.

Next steps: staff will follow up with the county assessment office as needed and provide historical assessed‑value comparisons to council.
