LOCAL DECISION REVIEW · OCTOBER 26, 2026

An Illinois shortlist needs the actual decision

Use the city search below to keep your service area specific. The 32 Illinois records shown here describe Radar's public coverage, not the state's pipeline. This worked example selects one existing Troy record and four municipal records; it does not rank the other Illinois projects.

Troy: preparation, adoption and recommendation are different

1. February 17, 2026 council minutes, page 1: preparation of a moratorium was directed. This meeting did not adopt it.
2. March 16, 2026 council minutes, page 3: the council adopted temporary moratorium Ordinance 2026-24. This is a regulatory restriction, not project permission.
3. June 11, 2026 planning minutes, pages 1–2: staff recommended an extension. A recommendation alone did not establish adoption.
4. September 21, 2026 council minutes, page 3, item 1: the council approved extension Ordinance 2026-57, 7–0. The minutes record approval on October 5.

Pursuit decision: defer estimating and bid preparation for this Troy lead. The documented extension defeats an assumption that the earlier scheduled expiry reopened the opportunity. First obtain the effective ordinance, any later action, site-specific permission and a named purchasing/package route. The minutes establish historical adoption, not current legal effect, expiry, permission or an open bid. The source cutoff is September 21, 2026, checked October 26; the project remains Status under review, with its whole-record check date retained.

What these public records establish

Use the actual city, village or county behind a record. Chicago market context does not identify the governing authority or permission for every Illinois site.

32 published public records on this page; 30 include the current field-level source report. Other previews retain their narrower published scope. These counts are records in Radar, not unique campuses, statewide totals or active bids.

Use the recorded-stage filters to choose a lead, then match a dated decision to its exact site, phase, authority and conditions. Check later amendments, withdrawals and restrictions. Missing public fields remain unknown; membership does not turn an uncertain claim into a verified fact.
