Reserve study puts Kiawah Island worst‑case replacement cost at $34.7 million, council told

John Walker, an engineering manager at Reserve Advisors, told the Kiawah Island Town Council on Feb. 3 that a catastrophic snapshot of the town’s capital assets would cost about “$34,700,000, as a total project cost for that.” He framed the number as a high‑level planning benchmark to inform reserve targets and capital‑planning discussions rather than an insurance appraisal.

The study maps component assets, assigns unit costs and useful lives, and projects 30‑year maintenance and replacement costs. Walker said his team used national construction cost databases and adjusted for local historical costs, and recommended updating the study every three to five years—more frequently if the council wants tighter accuracy.

Council members pressed on several line items. One council member, describing himself as the group’s “math and engineering guy,” said local replacement prices—especially for windows and paving—appeared lower than expected and urged adjustments for a local “Kiawah cost markup.” Walker said the firm had adjusted unit costs where local data showed higher pricing and offered to review specific items the council flagged.

The council also discussed the town’s unusually large reserves for a municipality of its size and whether some funds could be earmarked for strategic investments such as the planned Civic and Cultural Center. The town administrator noted the town had almost $29 million in unrestricted reserves and that many assets are covered by replacement‑value insurance, leaving roads as a primary uncovered liability.

Next steps: staff and the finance committee will use the reserve study to inform cash‑flow modeling and capital‑planning decisions and will consider updating the study on a 2–3 year cycle or more often where warranted.
