Officials say county fiscal‑impact model is out of date; county has locked legacy file, seeks update quotes

School board and county staff told the liaison committee the county’s fiscal‑impact model used to calculate proffers and public‑service costs is outdated and currently inaccessible.

School representatives said their construction and enrollment cost parameters have been updated recently and warned that proffer calculations based on old figures substantially understate the cost of school construction and other public facilities. A school board member said the county’s numbers were 20 years old in some cases and that those outdated inputs can undercut proffer requests from developers.

County staff said they possess the laptop that contains the model but cannot run the legacy program. The county reported obtaining a vendor quote to update or replace the model in the general range of $50,000–$60,000; a previously cited estimate of roughly $100,000 in earlier discussions has been revised downward in new quotes. Committee members said the county needs an accessible, modernized model (or an alternative approach) so proffer calculations reflect current construction and operating costs and to avoid shifting costs to existing taxpayers or schools.

No vendor contract was approved during the liaison meeting. County staff said they would pursue access to the legacy file and follow up with updated quotes and timeline estimates for a modernized model.
