The short version

Woodland Elementary created real elementary-school relief when it opened for 2025–26, but it did not add a single middle- or high-school seat. Queens Creek and Sand Ridge are already essentially full, Swansboro Middle remains substantially over permanent-building capacity, and Swansboro High is also over capacity. Even after the district sharply lowered its overall enrollment forecast, both secondary schools remain over capacity throughout the newest ten-year projection.

The core finding: Eastern Onslow’s problem is not simply total countywide seats. It is whether usable capacity exists where Hubert-area children are actually assigned to attend school.

NEW ANALYSIS · SEPTEMBER 7, 2026

What the new development-capacity workbook adds

A newly supplied working spreadsheet compares 2026–27 enrollment, 2023–24 capacity figures, earlier forecasts and estimated student impacts from nine development cases. It reinforces the central finding of this dossier: a countywide seat total can conceal serious crowding in particular attendance zones and grade levels.

Schools already above the workbook’s listed capacity

284

Current combined seat deficit in the five-school eastern cluster

497

Modeled eastern deficit if every listed approved and pending project is built

The eastern calculation covers Queens Creek Elementary, Sand Ridge Elementary, Swansboro Elementary, Swansboro Middle and Swansboro High. Their combined enrollment is 4,109 against 3,825 listed seats—a 284-student deficit, or 7.4%. Approved CREZ-2026-00002 increases the modeled deficit to 343. Adding every listed approved and pending project increases it to 497, or 13.0%.

The workbook attributes 411 students to five approved development cases and 239 to four cases marked “Not Yet Voted On.” Those groups must remain separate. Under its assumptions, approved projects alone would move Coastal Elementary, Dixon Middle and Trexler Middle from nominal surplus into deficit, increasing the number of over-capacity schools from 13 to at least 16.

Important limitations

  • Cell N8 uses the wrong school’s capacity. Dixon Elementary’s modeled overage is approximately 23.3%, not 17%.
  • The future-enrollment totals combine approved and not-yet-voted-on projects.
  • Columns called “Accuracy” actually report signed forecast error.
  • The workbook compares 2026–27 enrollment with 2023–24 capacity without documenting intervening capacity changes.
  • Enrollment definitions, development-yield formulas, phasing and buildout dates are not documented in the workbook.

For those reasons, Hubert United is publishing the source and analysis while treating the workbook as a working paper—not as a substitute for the official OCS capacity reports. Exact future percentages should not be repeated without these disclosures.

PUBLIC-SOURCE VERIFICATION · SEPTEMBER 8, 2026

What is documented—and what still is not

We checked the ten highest-priority data needs against the public OCS archive, the 2025 Numerix forecast, the May 2026 capacity report, Woodland Elementary redistricting materials and the February 2025 construction proposal. “Partial” means the public record answers part of the question but is not sufficient for a project-level or operational conclusion.

Priority data pointPublic-source statusWhat the record establishes
1. Current enrollment by school and gradeMissingPublic OCS-produced records provide actual 2025–26 Month-2 membership and forecasts—not verified 2026–27 actual counts by school and grade.
2. Current capacity by schoolMostly documentedThe May 2026 report lists permanent-building operational capacity and excludes mobiles. Mobile capacity and a complete functional/core reconciliation remain missing.
3. Capacity methodologySubstantially documentedOCS publishes room-type formulas and expressly excludes mobile classrooms.
4. Complete development inventoryPartialNumerix tracked 88 developments in spring 2025 and estimated roughly 9,000 undeveloped lots or units. That is not a current 2026 project table.
5. Project-by-project student impactsPartialNumerix publishes student-generation rates by housing type and plan area, but not current row-level calculations for every project or Rebecca’s nine cases.
6. OCS reviews of the nine developmentsMissingNo complete set of OCS impact reviews, calculations or communications was located publicly.
7. Forecast models and assumptionsMostly documentedPublic reports disclose historical membership, birth/cohort and GIS assumptions, generation rates and forecast tables. Raw inputs, workbooks and review comments remain missing.
8. Proposed eastern schoolsPartial; prospectiveThe 2025 proposal describes two 800-seat schools with planning costs and target dates. It does not prove land control, full funding, design contracts or construction authorization.
9. Woodland Elementary effectMostly documentedMaps, presentations, board actions and enrollment figures document the redistricting. Exact before/after movement counts and duration of relief remain unclear.
10. Day-to-day overcrowdingMissingMobile counts, class sizes, converted rooms, caps/transfers, lunch schedules and principal-level operational records are still needed.

Records we still need to pursue directly

  • Official 2026–27 actual enrollment by school and grade, with the count date and measure defined.
  • Mobile-classroom inventory and capacity, plus functional and core-capacity measures.
  • A current development inventory with units, status, phasing, buildout, attendance assignment and projected students.
  • OCS reviews, correspondence and calculations for the nine identified development cases.
  • Raw forecast workbooks, GIS inputs, development rows and OCS validation comments.
  • Exact Woodland before/after reassignment counts and duration-of-relief analysis.
  • Site-control, funding, contract, design and authorization records for the proposed eastern schools.
  • Operational crowding records from affected principals and central administration.

NEW INFRASTRUCTURE WORKSTREAM

Classroom capacity is not water-and-sewer capacity

A school’s instructional-room calculation does not establish that its drinking-water, sanitary-sewer, restrooms, cafeteria, fire-flow system and other core infrastructure can support the same population. Mobile classrooms can add instructional seats while every occupant continues to rely on infrastructure sized for the original building.

Corrected Queens Creek baseline

  • Permanent-building operational capacity: 563.
  • Official 2025–26 enrollment: 563—exactly 100% of permanent-building capacity.
  • Approximate enrollment before Woodland opened: 687—about 124 above capacity.
  • Rebecca’s newer working workbook lists approximately 706—143 above capacity—but its official source, count date and measure still require confirmation.
  • No verified record currently establishes that Queens Creek is more than 200 students over capacity.

Questions requiring records

  1. Who provides Queens Creek’s water and wastewater service, and is any infrastructure shared with Swansboro High?
  2. What student-and-staff population were the systems designed to serve?
  3. What are the rated capacities of the meter, service line, sewer lateral, lift station, pumps, grease interceptor and any on-site treatment components?
  4. What were monthly water use and wastewater flow during the past five years?
  5. Did pump runtime, blockages, backups, overflows, maintenance calls or utility consumption increase while enrollment exceeded permanent capacity?
  6. Were restrooms, drinking fountains, handwashing facilities, the cafeteria and sewer system evaluated before adding mobiles or exceeding permanent capacity?
  7. Do mobile classrooms contain plumbing, or do students rely entirely on the permanent building?
  8. Has the campus experienced inadequate water pressure, restroom shortages, sewer odors, backups, grease-interceptor problems or sanitary sewer overflows?
  9. Have OCS, ONWASA, the Health Department or NCDEQ performed capacity, condition or compliance reviews?
  10. Does OCS consider utility limits when calculating operational capacity, or only instructional rooms?
  11. What utility upgrades would be needed for additional students, mobiles or buildings?
  12. What permits, engineering records and agency correspondence support the campus’s present utility capacity?

This inquiry will be expanded across the eastern schools. The required dataset includes provider, design population, permitted capacity, actual consumption and flow, mobile populations, fixture counts, fire flow, pressure, line and pump capacity, alarms, backups, overflows, complaints, inspections, violations, maintenance and planned improvements.

Working rule: OCS should not describe a campus as functionally capable of supporting its population solely because a classroom formula produces enough nominal seats.

Related utility-capacity evidence

A separate 2020 ONWASA engineering report concerning Holly Ridge and Summerhouse demonstrates why school, development, water and wastewater capacity should be evaluated together. It projected a wastewater-capacity shortfall and called for design work to begin in 2020–21. That report does not directly measure Queens Creek or establish that the school’s utility system is overloaded.

Read Hubert United’s review of the ONWASA Holly Ridge–Summerhouse capacity study.

What Woodland changed—and what it did not

Woodland Elementary opened for the 2025–26 school year with an operational capacity of 840 students. Creating its attendance zone directly affected Queens Creek, Swansboro Elementary, Silverdale and Morton. The adopted process did not change middle- or high-school attendance zones.

  • Queens Creek declined from 687 students in 2024–25 to approximately 563 in 2025–26.
  • Swansboro Elementary declined from 593 to approximately 495–501.
  • The Board permitted eligible fifth-graders to remain at their former school if their families provided transportation.
  • After public comment, staff adjusted the Morton/Woodland boundary northeast along Grants Creek Road to Altman Lane/East Davis Road.

That was meaningful relief, not merely a paper exercise. But the students redistributed among elementary schools will eventually advance into the same secondary-school system. Woodland therefore relieved an immediate elementary bottleneck without resolving the Swansboro Middle and Swansboro High capacity problem.

Why districtwide “available seats” can be misleading

28,468

District permanent capacity

26,723

Current reported enrollment

1,745

Apparent districtwide surplus

An empty classroom elsewhere in Onslow County does not automatically help a Hubert student assigned to Swansboro Middle. Using that space may require boundary changes, longer bus routes, expansions, new construction or a combination of those measures. Capacity must be evaluated geographically and by grade level—not only as one countywide total.

The forecasts changed substantially

Forecast vintageGrowth assumptionLong-range projectionImportant context
2023 OREd series1.48% mean annual growth30,573 by 2032–33Older land-use and enrollment inputs
May 2025 Numerix1.20% average annual growth30,492 K–12 by 2034–35Included 88 tracked developments and up to roughly 9,000 undeveloped units/lots
May 2026 OCS series0.33% mean annual growth27,738 by 2035–36Updated actual enrollment, development assumptions and Woodland-era boundaries

The May 2025 forecast predicted 27,548 K–12 students for 2025–26. The following year’s report showed approximately 26,723—about 825 fewer students than predicted. Forecasts remain useful planning tools, but they are not promises. Birth rates, military movement, private, charter and homeschool enrollment, development timing, occupancy and boundary changes can all alter the result.

The important local point is this: even after the countywide projection was revised sharply downward, Swansboro Middle and Swansboro High still remain over permanent capacity throughout the newest forecast.

Mobile classrooms change the picture

Older reports sometimes show “campus capacity,” which includes temporary units. Newer reports emphasize operational capacity inside permanent buildings.

SchoolPermanent capacityCapacity including mobiles
Queens Creek Elementary563663
Sand Ridge Elementary573593
Swansboro Elementary537677
Dixon Elementary619959

A campus can therefore appear to have adequate capacity only because students are housed in temporary classrooms. The district continued budgeting for mobile purchases and remodeling: approximately $404,852 in FY 2024–25, $350,000 in FY 2025–26 and $270,000 in FY 2026–27.

Proposed construction is not the same as funded construction

A February 2025 presentation proposed a roughly $353 million countywide construction program. Among its concepts were a new eastern middle school and a new eastern elementary school.

Prospective projectEstimated investmentProposed substantial completionWhat these records prove
New Eastern Middle School$63.871 millionMay 2029Discussed in a prospective plan
New Eastern Elementary School$58.497 millionMay 2031Discussed in a prospective plan

The supplied records do not establish that either project is fully funded, formally authorized for construction, under design contract, attached to an acquired site or under construction. Until appropriations, contracts and current schedules are produced, they should be described as proposed—not promised.

Facility-condition findings

The 660-page 2021 Long-Range Facility Needs Assessment estimated ten-year maintenance and anticipated needs in 2021 dollars. It is a planning assessment, not an appropriation or construction authorization.

School2021 estimated maintenance needSeparate conceptual improvement estimate
Queens Creek Elementary$3.10 millionNo major expansion priced
Sand Ridge Elementary$2.68 million$4.85 million
Swansboro Elementary$3.63 million$5.25 million
Swansboro Middle$9.61 million$9.69 million
Swansboro High$4.75 million$6.41 million
  • Queens Creek and Swansboro High share an approximately 84.7-acre campus and principal entrance, creating periodic traffic conflicts.
  • Some unused land near Queens Creek was described as lower, wetter and part of the site drainage system.
  • Swansboro Middle carried the largest estimated maintenance need among the five schools reviewed.
  • The Swansboro High assessment identified parking, drainage, mechanical, lighting, track and field-lighting needs.

What planners knew in 2021

The 2021 Onslow County Schools Long Range Facility Needs Assessment is important historical evidence. Its enrollment model did not simply extend a line on a graph: researchers considered subdivision growth, permit histories, information from local developers and planners, births, migration and student cohort patterns. The assessment therefore shows that the relationship between residential development and school demand was formally studied years before the current growth debate.

School2021 permanent operational capacityEnrollment projected during the ten-year period2021 planning signal
Queens Creek Elementary563Approximately 568–602Slightly to moderately above permanent capacity
Sand Ridge Elementary573Approximately 639–666Persistently above permanent capacity
Swansboro Elementary537Approximately 682–721Substantially above permanent capacity
Swansboro Middle912Approximately 831–943Approaching or exceeding capacity in later years
Swansboro High1,240Generally below capacity in the 2021 forecastNo immediate capacity overage projected at that time

The report’s countywide warning: the growth pattern used by the Board of Education and County Commissioners suggested that approximately one new school would be needed every two years over the following decade.

The report also separated permanent “bricks and mortar” capacity from campus capacity that counted mobile classrooms. That distinction matters: temporary classrooms can add seats without expanding cafeterias, media centers, administration, restrooms, traffic circulation or other core facilities.

How to read this evidence: these are historical projections prepared in 2021, not current enrollment figures. They show what officials and planners were told to anticipate; they do not prove that every projection occurred or that any single development caused a particular capacity problem. The current figures elsewhere on this page remain the better measure of present conditions.

Annual Programs of Work

The six Programs of Work identify recurring maintenance and equipment items, including Swansboro Middle paving and roofs; Sand Ridge gutters, playground equipment and access controls; Swansboro Elementary flooring, mobile ramps, playground equipment, cameras and access controls; and Swansboro High HVAC, drainage, cameras, painting, chiller and intercom work.

However, many supplied tables show the full budget still remaining, with no invoice or encumbrance. Appearance in a Program of Work establishes that an item was listed and budgeted for that document—it does not necessarily prove completion. Completion requires invoices, contracts, inspection or closeout records.

Records-integrity notice

Five school-level ADM documents were supplied under filenames that do not match their internal contents. Hubert United preserved every filename exactly as received.

Filename suppliedActual internal content
QCES ADM.docxSwansboro Elementary
SRES ADM.docxQueens Creek Elementary
SBES ADM.docxSwansboro Middle
SBHS ADM.docxSwansboro High
SBMS ADM.docxDuplicate Swansboro High image

No actual Sand Ridge ADM history appears in this group. Small unexplained differences also exist between the screenshots and the May 2026 capacity report: Swansboro Elementary shows 495 versus 501, and Swansboro Middle shows 1,032 versus 1,035. Hubert United will not silently select a preferred figure where the records do not explain the difference.

What the records establish

  1. Eastern Onslow has a localized capacity problem despite apparent districtwide space.
  2. Woodland materially relieved four elementary attendance zones.
  3. Woodland did not add middle- or high-school capacity.
  4. Swansboro Middle is substantially over permanent-building capacity.
  5. Swansboro High is over permanent-building capacity.
  6. Queens Creek and Sand Ridge are essentially full immediately after Woodland opened.
  7. Residential development is expressly incorporated into enrollment forecasting.
  8. The forecasts have changed substantially and must be identified by date and methodology.
  9. The district has discussed an eastern middle and eastern elementary school.
  10. The supplied records do not establish that either proposed eastern school is fully funded.
  11. Mobile classrooms remain part of the district’s active capacity strategy.
  12. The records production contains mislabeled, duplicated and missing ADM material.

Open questions Hubert United is pursuing

  • Correctly labeled ADM histories, including the missing Sand Ridge record
  • Current mobile-classroom counts, locations and actual classroom utilization
  • Completion status, invoices and closeout records for eastern Program-of-Work items
  • The current Capital Improvement Plan and county appropriations
  • Funding, site acquisition, design and schedule status for the proposed eastern schools
  • Updated feeder projections showing Woodland students advancing into middle and high school
  • The separate Woodland-impact forecast and spreadsheet tables referenced by Numerix but not supplied

Source archive

Hubert United has published the source material so residents, journalists, candidates and public officials can inspect the evidence rather than relying solely on our interpretation.


Methodology and limitations: Official OCS records and independently supplied working papers are identified separately. “Capacity” means permanent operational capacity when drawn from OCS reports; the September 7 workbook uses a 2023–24 capacity column and does not independently define the measure. Forecasts are identified by vintage. Approved and pending developments are separated. Proposed schools are not described as funded without appropriation or contracting evidence. Corrections and additional records will be dated and incorporated under Hubert United’s published editorial standards.
