Moving to Arnold: Pros, Cons & What to Know

A real hazard-mitigation success story

Arnold's 1993 flood damaged more than 225 properties. The city's response -- a ~500-home federal buyout program (1994-2005) -- converted former floodplain into current greenspace and trails, cutting the 2008 flood's damage to just $12,000 versus 1993's $1.6 million.

Housing priced close to the Missouri average

Arnold's average home value ran approximately $279,059 this pass, running close to Missouri's own $268,423 statewide average -- neither a premium nor a bargain outlier.

A distinct, Jefferson County tax picture

Jefferson County's own property tax rate runs modestly below Missouri's statewide average on the one source found this pass, a real, distinct contrast to the higher-taxed St. Louis County suburbs built elsewhere in this project's Missouri batch -- though Arnold's own 11.6% combined sales tax rate runs substantially above the state average.

A real local manufacturing and retail base

LMC Industries, a real, long-standing tool manufacturer, anchors part of Arnold's economy, alongside a substantial big-box retail corridor serving southern Jefferson County.
