From Fewer Students to Fewer Dollars

The K-12 enrollment forecast turned into a recurring revenue headwind, set against the district's cash cushion

Fewer students means less money, every year. Iowa funds districts per pupil. ICCSD's own cohort-survival forecast projects roughly 750 fewer students by 2030 under the Baseline. At the state foundation rate that is a recurring ~$6.8M/year hole in the operating budget. It arrives while the district already runs one of the thinnest cash cushions of any large Iowa district.

The bridge, in four steps

Enrollment falls about 752 students by 2030 under the Baseline scenario, from 14,227 K-12 in 2025 to 13,475 in 2030. The decline is demographic. Johnson County births peaked in 2016 and feed smaller kindergarten classes.
Each lost student takes about $9,000 of revenue with it. Iowa's funding formula pays districts per pupil. Fewer students means a smaller combined state-aid and property-tax foundation amount the following year.
That compounds to a recurring ~$6.8M/year shortfall by 2030 against the 2025 revenue base. It also adds up to roughly $18M total (2,027 student-years) of lost state aid over 2026 to 2030 as the decline phases in.
It lands on a thin cushion. ICCSD holds about 31 days of net cash, around $18M in the General Fund, against a 90-day target of about $52M. A recurring $6.8M/year drain is roughly a third of the district's entire current cash balance, every year.

Enrollment from the ICCSD cohort-survival forecast (iccsd-enrollment-forecast.html), K-12 BEDS basis. Per-pupil revenue uses the site-standard $9,000 all-in state foundation figure. At the narrower regular-program district cost per pupil of about $7,800, the Baseline headwind is about $5.9M/year. Still a structural drag.

The district is already about $34M below a 90-day cushion. A recurring revenue decline does not just block rebuilding that cushion. Left unmatched by spending cuts, it eats into what little remains. That is why the enrollment forecast is a financial document, not just a demographic one.

The decline costs the district a cash cushion's worth of revenue every year. The 752-student Baseline decline works out to a recurring ~$6.8M/year revenue headwind by 2030, a range of about $6.1M to $8.3M across scenarios, against a General Fund holding only about 31 days of cash. Closing the gap means either reversing the enrollment trend, which is largely demographic and hard to move, or cutting recurring operating costs by a similar amount. Doing neither spends down a cushion that is already the thinnest among large Iowa districts.
