Concurrency at Northgate

Northgate is a 240-unit single-family subdivision proposed in the City of Harlow (pop. 110,000). The city's concurrency ordinance requires that public facilities be available at the adopted level of service at the time of occupancy. The north-area elementary school sits at 1,152 of 1,200 student stations. The district's adopted student-generation rate for this housing type is 0.30 students per unit, and the city's consultant estimates 72 elementary students from Northgate. The district's capital plan funds a new elementary in FY2031; Northgate buildout is projected for 2027-2029. The access intersection is at LOS E and degrades to LOS F under the city's own travel-demand model by 2029 without a widening that is unfunded and unscheduled. The applicant has offered $340,000 toward a traffic signal but no school mitigation, arguing school capacity is the district's problem, not the developer's.

1. What does the concurrency ordinance require you to determine, and what are your defensible options?

Read the worked answer

The ordinance asks one question: will the adopted level of service be met at the time of occupancy? Not at buildout of the district's capital plan, and not after buildout of the surrounding area - at occupancy.

The determination has three steps, each of which must be documented in the record:

  1. Apply the adopted LOS standard and the adopted student-generation rate. Do not substitute a negotiated rate; if 0.30 is adopted, 72 students is the finding.
  2. Compare demand against capacity at the time each phase is occupied. Northgate adds 72 students to 48 available stations. Capacity fails before the first CO.
  3. Determine whether the failure is caused or worsened by the project and whether mitigation can cure it.

Defensible options:

  • Deny without prejudice, or defer pending a capacity solution, with written findings. Defensible only if the standard is unambiguous, the demand calculation is transparent, and the record shows the project's contribution.
  • Condition approval on proportionate-share mitigation sufficient to create or secure capacity - a school site dedication, a payment tied to the adopted impact fee or proportionate-share formula, or a capacity-funding agreement with the district.
  • Phase the approval so that no certificate of occupancy issues before the FY2031 capacity exists. This is often the most honest option, but check it against your state's vesting and takings law and confirm the delay is not so long as to amount to a denial.
  • Administrative fix: a temporary attendance-boundary reassignment to a school with capacity, documented in a district letter.

What you cannot do is approve on the strength of the $340,000 signal offer. Traffic mitigation does not address the school finding, and accepting it as though it did would be a mistake of law written into the record.

2. The applicant argues the school is the district's problem. How do you handle proportionality, and what limits your leverage?

Read the worked answer

The applicant is half right, and the half that is right matters.

The developer's obligation is not to build a school. It is to bear no more than its proportionate share of the cost of the capacity its residents consume. Seventy-two students against 1,200 stations is 6% of a school. If a new elementary costs, say, $30 million, the project's proportional contribution is on the order of $1.8 million - not $30 million, and not the $340,000 signal money redirected.

How to get a defensible number:

  • Use a methodology adopted in advance, not a figure negotiated at the counter. A school impact fee schedule or an adopted proportionate-share formula is defensible; a number invented during a permit review is not.
  • Show the calculation in the staff report, including the generation rate, the cost basis, and the share. Negotiated exactions invite both equal-protection and rough-proportionality challenges.
  • Tie the exaction to the impact. If the project pays a proportionate share, the district needs a credible funding commitment for the FY2031 school; otherwise the money is collected with no capacity and the nexus is thin.

What limits your leverage:

  • You cannot require mitigation greater than the project's fair share, and your state's concurrency or adequate-public-facilities statute governs whether the test is 'available at occupancy,' 'reasonably available,' or 'financially feasible.' Read it before you write findings; the analysis changes materially.
  • The signal is a red herring and should be treated as such in the record, but the LOS F finding on the intersection is independent and must be resolved on its own terms.
  • Finally, note the systemic issue upward. A concurrency framework that is only applied project by project will keep producing these standoffs; the ordinance and the capital plan are the actual problem, and the council should hear that in a separate memo.

3. The council wants a simple approve-or-deny recommendation by next week. What are the litigation and credibility risks of each path, and how do you frame the choice?

Read the worked answer

Frame it as a choice among three records, all of which are defensible if built properly and none of which is risk-free.

Denial. Risk: the applicant will argue the city relied on an unadopted standard, used an inflated generation rate, or failed to show causation; in many states a concurrency denial must rest on substantial competent evidence in the record. Mitigation: attach the generation rate, the capacity letter from the district, the occupancy timing, and the ordinance text. A denial supported by that packet is strong; a denial supported by staff opinion is not.

Conditional approval with proportionate share. Risk: rough-proportionality and nexus challenges, and a mitigation payment with no funded capacity behind it. Mitigation: adopt the formula in advance, show the arithmetic, and require a district commitment or an interlocal agreement before the payment is collected.

Phased approval tied to FY2031. Risk: a court may treat a multi-year occupancy hold as a compensable taking if the delay is indefinite or the district's funding is speculative. Mitigation: a short, defined phase schedule, a district letter confirming the funding year, and a reopener if capacity arrives early.

What to say to council: these are not three flavors of the same decision; they allocate the shortfall to different parties. Denial puts it on the applicant and the housing supply, conditional approval puts it on the developer's pro forma, and phasing puts it on the future residents. That is a policy choice the council is entitled to make, but it must make it explicitly in findings rather than letting staff's technical recommendation make it by default.

Document every meeting. In a case like this the record is the decision.
