Marshalltown data center moratorium (Swarm Systems Edgewood Industrial Park proposal)
moratorium Motion approved 5-2 on 13 July 2026; ordinance adopted 24 August 2026; land offer expired 11 September 2026; moratorium runs to 23 November 2026, extendable 60 days
 Swarm Systems (proposal) City of Marshalltown
The Marshalltown City Council approved a four-month data center moratorium motion 5-2 at a 13 July 2026 meeting, after a six-month pause failed 4-3 about three weeks earlier. The moratorium ordinance was adopted on 24 August 2026 and halts acceptance, processing and issuance of data center permits, applications and zoning amendments until 23 November 2026, with a possible 60-day extension. Swarm Systems CEO Amir Atefi presented a plan to buy 21 acres in the Edgewood Industrial Park for a 150,000-square-foot data center, and said he would wait out the moratorium. Records made public after the offer expired show Swarm Systems offered the city $1,113,200 on 21 July 2026 for about 29.33 acres, then about a month later the same amount for 21.77 acres (about $51,135 an acre), with closing by 31 March 2027 and contingencies requiring the moratorium to lapse and zoning acceptable to the buyer. The council deadlocked on acting on the offer after the 24 August 2026 presentation and it expired on 11 September 2026. CEO Amir Atefi said the company is also looking at other sites in Iowa and other states but has not moved on from Marshalltown.

Policy context

What governs a data center in Iowa

The policy layer for Iowa lives in three companion references: the Iowa Data Center Moratorium Tracker for every state measure and local moratorium on record, the Water Tracker for the water rules that touch a site, and the Grid Operator Watchlist for the large-load rules of the RTO or utility that decides whether it can energize.

Seven references, one system

Capital, delay, policy, water, grid, permits and scarcity are one system seen from seven sides. Each reference is primary-sourced, refreshed on a schedule, and links into the others, so a project can be followed from the money committed to the docket that stopped it.
