Observed enrollment · Steps 1–3; optional mathAugust 28, 2026 preliminary enrollment count
534 students in the two current schools; 112 fifth graders leave, leaving 422 in K–4. Current kindergarten is 68. Carrying those counts forward gives the 490-child benchmark.

District proposal · Steps 1 and 3; optional math; our askResilient Schools proposal, August 25, 2026
Stated capacity of 492 in the current Bear Creek building; projected total enrollment of 392–445 in 2027–28 and 403–462 in 2030–31; projected 522 area residents in 2030–31. Also supports the proposed relocations and closure placement rules.

The enrollment ranges are district projections, not confidence intervals. If the BoardDocs PDF does not open, use the district proposal page and its presentation link.
District forecast revisions · Optional enrollment pressureBVSD projections changed between published reports
For the same target year, 2029-30, Mesa’s projected enrollment changed from 224 to 202, while Bear Creek’s changed from 272 to 310. These revisions illustrate that forecasts can change in both directions. They are forecasts for the separate schools, not realized enrollment changes or forecasts of the proposed combined school.
October 21, 2025 Long Range Planning Update, slide 17 (table) and slide 20 (chart); February 10, 2026 Annual Enrollment Trend Report, p. 9. The October presentation reused the January 2025 forecast; the February report uses the January 2026 update. The comparison holds the target school year fixed.
Observed enrollment · Step 2Five official October head-count reports
Combined kindergarten counts of 82, 77, 58, 84 and 76 in 2021–22 through 2025–26. These establish the historical range of 58–84; they do not assign probabilities to future class sizes.

Research collection · Opening; Step 3 historical comparisonDistrict enrollment archive, 2014–15 through 2025–26
The collection contains twelve October head-count years, 2014–15 through 2025–26. Across eleven combined K–4 to following-year grades 1–5 comparisons, the largest net decline is 21 pupils (3.9%), from 535 in 2019–20 to 514 in the 2020–21 pandemic school year. Aggregate counts measure net change, not individual retention, family decisions or the cause of departures. The smallest combined kindergarten in this record is 58. Step 2 uses the latest five complete years; the ten-year presentation series begins in 2016–17.
CDE Head Count Summaries, p. 1, Bear Creek and Mesa rows in all twelve years. The historical comparison excludes incoming kindergarten and graduating fifth grade and combines both schools to avoid counting transfers between them as departures. Scenario percentages divide net losses by the 422 current K–4 pupils. They hold incoming kindergarten at 68, or at the historical minimum of 58 as a sensitivity check, not a forecast.
Observed attendance patterns · Optional resident math2025–26 elementary enrollment-pattern matrix
Of 502 residents in the four areas, 415 attended the two current schools, 27 attended Montessori and 12 attended High Peaks. Applying all three shares to the projected 522 residents gives about 472 resident pupils, conditional on both full focus-school shares shifting, not a forecast. This is about 10 above the projected upper enrollment of 462 and 20 below capacity of 492. Alternatives model no shift, half of both shares, and Montessori alone. The 2025–26 schools also enrolled 98 outside-area choice students and 23 placements; these are not fixed cohorts added to the future. Residents-only capacity examples use hypothetical resident counts of 560 and 545.
Page 1. Resident columns: Bear Creek, Mesa, Optional Bear Creek/Mesa and Optional Bear Creek/Creekside. The 98 comprises 75 outside-area in-district choice students and 23 out-of-district students; the separate placements have no residential breakdown here.
District explanations · Step 3; our askBVSD declining-enrollment FAQs
Managing choice enrollment near capacity; closure assignments and applications; school-specific open-enrollment, space and staffing plans for receiving schools; preschool timing; and investigation of School Age Care expansion. The FAQ does not specify whether receiving-school plans affect only new applicants or also current students. The interpretation of the enrollment gap is this page’s analysis.

District policy · Step 3; our askJECC and JECC-R: School assignment and open enrollment
JECC generally continues granted open enrollment through the school level, subject to school-assignment or enrollment adjustments. JECC-R gives neighborhood residents registration priority and makes outside-area admissions dependent on space. These policies do not establish unconditional protection for current receiving-school students and must be read with the proposed closure rules.

District boundary decision · Optional resident mathBear Creek/Creekside attendance-area change
The former optional Bear Creek/Creekside area becomes Bear Creek only in 2026–27. It is already effective for the August 2026 benchmark; no separate extra enrollment increment is added to the scenarios.

School locations · Optional enrollment and future mathHigh Peaks and Douglass school addresses
High Peaks is currently at 3995 E. Aurora Avenue; Douglass is at 840 75th Street. The proposed High Peaks move is farther east from the Mesa neighborhood. Future enrollment responses are explicit assumptions in the scenarios.

District counts and staffing guidance · Optional class-size mathGrade counts, capacity rounds, staffing formula and class-size goals
The 490-child benchmark by next-year grade is 68, 68, 88, 88, 82 and 96. Illustrative balanced allocations compare three and four classes per grade. Under that allocation assumption, 21 classes meet all BVEA grade-specific goals. Actual program rosters and room allocations are unverified. The February 2026 capacity table lists 3.5 capacity rounds for the current Bear Creek building; multiplying by six K–5 grades gives 21 as an organizational equivalent, not a verified room inventory.

Alternating open and acoustically divided classrooms was associated with faster reading-fluency development in the enclosed condition, with larger differences among children with poorer attention or speech perception in noise. This study did not measure the current Bear Creek building.

University planning timeline · Optional enrollment pressure; our askCU Boulder South: development timing and housing
Future housing includes faculty, staff and students. Site planning has not begun; university construction cannot start until flood-protection work is completed, with the earliest construction likely in 2030. This is not an occupancy date or a K–5 enrollment estimate.
