Maquoketa Valley Electric Cooperative told Piazza officials that cooperatives are required to try to serve prospective loads but will require new large users to fund engineering studies and upgrades. The co‑op said it would require new generation and security deposits in many cases.

Dozens of residents urged the Piazza City Council to prioritize water, noise, property‑value and health protections, criticized survey outreach and called for independent baseline testing, environmental studies, traffic reviews and enforceable penalties in any ordinance.

Council members signaled support for extending the current data‑center moratorium and instructed staff to place a specific extension length on an upcoming agenda so the council can vote. Members suggested 6 to 12 months with language allowing earlier termination if work finishes sooner.

Alliant Energy told the Piazza City Council that reliability for existing customers would not be compromised and that large users pay for the infrastructure needed to serve them. The utility urged transparency and said regulators oversee protections for ratepayers.

Zach Shierman of Dubuque Building Trades and IBEW Local 704 urged the council to support the data‑center project, saying construction will bring hundreds of union jobs and long‑term benefits to the local tax base. He asked that any agreement require union labor and a preference for workers within 50 miles.

Developer Jim Conlon, part owner of the controlling entity for the proposed site, told the council the project would deliver substantial tax revenue, use union labor and either take grid power or build behind‑the‑meter generation connected to the grid for reliability.

B&K engineer Ben presented a proposed tower and well site with tie-ins to existing mains, redundancy via a pressure-reducing station and preliminary cost estimates (tower manufacturer quotes in the multi-million-dollar range, a deep well estimated under $1 million, and additional work for the well house, shop and water main). The team plans to bid the tower first and phase later work.

Multiple residents told the Peosta City Council they want the current moratorium extended and a strict local ordinance to prevent hyperscale data-center development, citing lost cropland, restoration failures and local-control concerns; council said a ban may not be legally possible but pledged to pursue strict rules and may extend the moratorium.

Staff proposed $50,000 over two years for PBCA with an internal loan to front funds until TIF certification; council members asked for project-level budgets or a short list of programs, a sample agreement and reporting cadence before releasing funds.

Council members summarized a meeting with developer Slavic about unsold commercial and apartment lots in Thunder Valley; options discussed included marketing assistance, the city purchasing some lots, or limited financial support — councilors warned against creating false expectations and asked staff to continue conversations while avoiding commitments without formal proposals.

Multiple residents raised concerns about low‑frequency vibrations, inaudible noise (dB levels) and potential health impacts from data‑center equipment and turbine generators; the developer recommended acoustical testing and comparative site visits and agreed to provide industry studies.

Council and staff explained the likely procedural steps if a project advanced: voluntary annexation of county parcels, rezoning or ordinances addressing all data centers, development agreements to enforce water, road and reclamation terms, and limits on a municipality's ability to ban uses under existing case law.

Developer estimated roughly 3,000–5,000 construction jobs over the build period and about 50 permanent operations jobs; councilors and residents said they will require road‑use agreements, reclamation plans and protections for farmland and local services during construction.

Developer told the council hyperscale data centers (roughly 350 MW+) must be sited where large transmission substations exist or else build on‑site natural‑gas power; the presentation framed why available local grid infrastructure limits candidate sites.

Developer described closed‑loop cooling with an initial fill of roughly 3.5 million gallons and small annual top‑ups; residents and councilors asked for water‑supply agreements, DNR permitting details and enforceable contractual limits if a project moves forward.

Developer Jim Conland presented a concept for a hyperscale data center on county land south of Highway 20 and answered council and resident questions about power, water, noise and mitigation; councilors stressed the project remains a concept and would require annexation, zoning and binding agreements before moving forward.

Council members said they'll press the Iowa DOT next week for Highway 20 corridor prioritization and discussed offering a roughly 50% local cost share (or a $10 million not-to-exceed option) rather than using SRF loans that would delay construction.

Multiple residents urged the Peosta City Council to expand outreach and formally include public comment in work sessions as the city studies a proposed data center; councilors said a survey is live and they plan targeted work sessions on zoning, water, and technical impacts.

Spirit Financial told the council the city’s share of a potential Highway 20 diamond interchange could be $8–$10 million and reviewed 15-year debt scenarios tied to the Cap Drive project; the council also approved contract amendments, change orders and pay estimates for local infrastructure projects.

Council reviewed Cap Drive engineering, potential SRF eligibility for water components, and options for local match to influence DOT prioritization on Highway 20 improvements; members discussed offering a 50% match versus higher percentages and asked staff to prepare materials ahead of DOT deadlines.
