This page states the findings and their sources. Everything behind them, the fifteen-record chain, the consultant's tables in full, the Village's three-year TIF history and every limit on every figure, is in the full record.

Where this stands

The Village of Northbrook has not created a downtown tax increment financing district. It has not published an eligibility report. Nothing has been certified, and no boundary has been drawn.

What the Village did on May 26, 2026 was adopt Resolution 2026-R-102 and approve a purchase and sale agreement for a Village-owned downtown parcel. The record of that single meeting establishes four things:

  • Ordinance 2026-32 approved a real estate purchase and sale agreement with The Habitat Development Company LLC for Lot 2 of 1657 Shermer Road, the former Grainger property. The Village Attorney described a proposed $10.5 million sale agreement containing due diligence, zoning, and TIF review provisions. The sale has not closed.
  • Resolution 2026-R-102 is titled Providing for the Potential Reimbursement of Eligible Costs. The Village's own plain-language summary describes the same action only as authorizing a study. Both can be true of one instrument. But two years earlier, for a proposed Green Acres TIF, the Board adopted A Resolution Providing for an Eligibility Study and Report and a Redevelopment Plan and Project ... and for the Potential Reimbursement of Related Eligible Costs. That title names both jobs. The downtown title names only the second, and the Village described only the first.
  • The Board reserved the public hearings on both downtown developments to itself rather than routing them to the Plan Commission. On August 25 it reversed that for the Pulte application.
  • Every vote was 6 to 0.

Separately, District 30's superintendent told her board in writing on June 11 that Habitat has requested up to $3,500,000 in TIF funding to reimburse eligible expenses. The agreement expressly contains TIF review provisions, and the reimbursement request existed before any downtown eligibility report or redevelopment plan had been published.

The sequencing is its own signal. For Green Acres the Village signed the developer agreement on December 12, 2023 and adopted the study resolution four weeks later. Downtown, the land sale and the TIF resolution were items 10.D and 10.F on the same night.

District 30 says the base value would be zero

This is the part that decides most of the money, and it is not complicated.

When an Illinois TIF district is certified, the assessed value inside it is frozen. Schools, park district, library, township, and county keep taxes on that frozen base. Everything above it, the increment, goes to the TIF fund for up to 23 years.

The Village bought 1657 Shermer Road from W.W. Grainger, Inc. in May 2018 for $8 million, and municipally owned property is exempt. Under the TIF Act the county clerk sets the initial value from the most recently ascertained value and totals the district's initial value from taxable property. District 30's position is that the currently exempt parcel would therefore contribute nothing to the base if a district were formed under present conditions.

District 30's memorandum states the consequence, attributing it to the Village's Director of Planning and Development: because the Grainger property's baseline EAV is frozen at $0, all new property tax growth generated by this development over the next 23 years will be diverted into the Village's TIF fund.

If the county clerk ultimately sets a zero initial value, the taxable value created by the redevelopment would generally become increment for the life of the district rather than entering the ordinary base the schools levy against. That does not mean the schools get nothing. Illinois law requires payments from a TIF fund for school costs attributable to assisted housing units, and separately permits agreed payments toward a district's capital costs. What matters is whether the downtown plan uses them.

Timing could matter a great deal, but conveyance alone does not guarantee a base above zero. The statute directs the county clerk to use the most recently ascertained value, so the real question is what taxable value Cook County has established for the parcel when the district is adopted. The published record answers neither that nor the Village's intended timing. That is the question worth asking, and it fits in a sentence.

One further point that is widely misunderstood. Illinois Department of Revenue guidance confirms that TIF increment is excluded from the value used to calculate a school district's PTELL limiting rate. Because the levy is a capped dollar amount rather than a rate, removing value from the base does not reduce what the district asks for. District 30 argues this shifts more of the operating burden onto property outside the district. The effect on any individual bill depends on the levy, new property, assessments and rates.

The students were already counted

The argument over how many children a 300-unit building produces has been running between a developer's projection and a district's rebuttal. It did not need to.

On January 21, 2025, sixteen months before the Village authorized its TIF study, Glenbrook High School District 225 received a Subdivision Yield Analysis from Woolpert and Cooperative Strategies. Rather than applying a national table, the consultants placed enrolled students geographically and matched them to the buildings they live in. For District 30, 243 students live in 1,255 multifamily attached units, a measured yield of 0.19 students per unit.

The study's development section lists 1657 Shermer (Grainger Site) by name and projects it at 383 units producing 71 K-12 students, 49 of them in District 30 and 22 at Glenbrook. Scaled to Habitat's 304-unit proposal, that is about 56.

Three estimates, using three different methods, now exist. Nobody has put them side by side:

  • District 30's superintendent, using published mid-rise multipliers: 38 to 50 school-age children.
  • District 225's consultant, modeling the same site at deliberately maximum impact, scaled to 304 units: about 56.
  • The measured local yield of 0.19 per unit, applied to 304 units: about 58.

Three methods, drawing on District 30's own analysis and on the District 225 consultant study, landing between roughly 40 and 60 students. The second and third are separate calculations from the same report rather than separate sources. For context on why the range matters: at the Sterling Place development on Techny Road, the developer's study projected 15 elementary students. District 30 reports 43 enrolled for 2026-27, an undercount of 187 percent.

Northbrook already did this once

The same consultant's report contains a second entry that reframes the whole discussion.

Northbrook already has an active TIF. The Northbrook Court II TIF was approved on October 30, 2023 over the shopping center site, more than 100 acres. The January 2025 study models the residential redevelopment there at 2,000 units producing 557 K-12 students.

How that TIF was adopted is the best available preview of how a downtown one would be. Seven instruments did it: three ordinances creating the district, one resolution on reimbursing capital spending from future borrowing, two creating a business district and imposing a new local sales tax, and one approving the developer incentive agreement with note issuance. The minutes record them ADOPTED BY CONSENT VOTE [7 TO 0] on a single omnibus motion. That is ordinary municipal practice, and it is also what a downtown adoption is likely to look like: a package, not a debate on one ordinance.

And here is the part of the record that cuts the Village's way, which is also the most useful thing in the whole file. Northbrook has already written schools into a TIF plan. The Northbrook Court II redevelopment plan budgets, against a $155 million total, two line items aimed at the schools: $15 million in statutory school district payments for costs attributable to assisted housing units, which the plan says will rise automatically if the required amount is larger, and $25 million in capital cost payments to school districts. The plan sets those capital payments as the difference between the required annual payments to Districts 225 and 28 and the maximum possible statutory school district payment (40% of increment generated by the residential portion of the redevelopment project).

Northbrook has also twice declared a TIF surplus, on terminating the original Northbrook Court TIF in 2023 and the Dundee Road/Skokie Boulevard TIF in 2024, returning money to the taxing bodies. A terminating surplus is not a guaranteed annual payment, but the plan provisions are something better: a written formula naming the districts.

So the downtown question is not whether a TIF can pay schools. Northbrook's own 2023 plan shows it can and did. The question is whether the downtown plan carries the same provisions, better ones, or none. And on January 9, 2024 the Village authorized an eligibility study for a Green Acres TIF district that has not appeared in the record since. A study does not have to become a district.

Now the number that matters. Across the entire Glenbrook 225 area, five feeder districts and every development the consultants could find, the study counted 2,995 planned units producing 928 K-12 students. Northbrook Court and the Grainger site together account for 2,383 of those units and 628 of those students.

Roughly four out of five new units, and two out of three new students, sit on two sites that are either already inside a TIF district or proposed for one.

So the question in Northbrook is not really whether to create a TIF district. It is whether two properties projected to generate a large share of the area's new enrollment will both have substantial portions of their new tax growth captured inside TIF districts, and what enforceable protections the school districts get in return.

And the 928 is already stale. The study closed in January 2025, so it does not include Meadow Plaza at all. Pulte's 150 condominiums arrived more than a year later.

What the record does not establish

  • No district exists. No boundary, base value, budget, or increment projection has been published. Every figure describing what a district would capture is an estimate by an interested party.
  • The $3.5 million is a contractual request contingent on a district being created, not an award or an appropriation.
  • The zero base is District 30's stated understanding of what a Village official told it. No Village statement in the reviewed record confirms the intended timing, and the initial value is not fixed until the county clerk certifies it.
  • The sale has not closed. The Board approved a purchase and sale agreement whose conditions include zoning approvals.
  • Illinois law requires school payments for qualifying TIF-assisted housing and permits agreed capital-cost payments. What a downtown plan would contain is not established.
  • The three student estimates are three methods, not three independent sources. Two are separate calculations from the same District 225 study.
  • The January 2025 study sets its applied yields deliberately above measured averages to model maximum impact, and rounds up. Its 383-unit assumption and bedroom mix are not what Habitat has filed, so the scaled figures here are approximations.
  • Northbrook Court's 2,000 units are the program identified in January 2025 and may have changed. Parcel-level TIF boundaries were not examined.
  • This is not legal or financial advice, and not an assessment of anyone's motives. It is what the published records show, and where they stop.

What to watch

  1. The eligibility report. Read the base value first, before the boundaries or the budget.
  2. The certification sequence for 1657 Shermer Road, relative to conveyance and reassessment.
  3. The Joint Review Board minutes, where the districts' positions become formal record rather than correspondence.
  4. Whether the January 2025 yield study is put in front of the Village Board. It is the only measured, independent student projection that exists for these sites.
  5. The developer impact fee review, which is an alternative route to the same problem.
  6. What the Northbrook Court II TIF has actually delivered since 2023. It is the closest evidence for what a downtown district would do.

Where this came from

Every document here is public and was published by the Village of Northbrook or a school district on its own website. None of it was in one place. The base-value warning sits in a superintendent's memorandum inside a school board packet. The student count sits in a consultant's report attached to a high school district's agenda in January 2025. The $10.5 million price is spoken by the Village Attorney in the minutes, not in the meeting summary. The resolution's operative title is in the agenda, not in the description of it.

That is the ordinary condition of local government: the record is complete, public, and effectively unreadable, because the pieces of one decision are filed by separate bodies that do not index each other.
