Map: All 74 in-scope PPS schools with building utilization
Each marker sized by 2025-26 enrollment and labeled with building utilization (enrollment ÷ 2021 functional capacity). Red fill marks schools at less than 50% building utilization. A purple ring indicates an unreinforced masonry (URM) building.
Enrollment trends: every school, 2018 → 2025
Each thin line is one school's enrollment indexed to its 2018 baseline (2018 = 100). A flat line means stable enrollment; lines sloping down are losing students. The bold orange line is the district-wide total. Use the search box below to find schools and check one or more to isolate them on the chart; hover a line to identify it. Shows 70 of the 74 in-scope schools (4 schools without complete 2018–2025 history are omitted. Source: NCES CCD (2018–2023) + Oregon ODE (2024–2025).
Caveat: 19 schools had their attendance boundary or grade configuration redrawn inside this window; via DBRAC (2018) or the Southeast Guiding Coalition (SEGC, 2023). For those rows, some of the apparent enrollment change reflects catchment redraws rather than pure demand change. See the "Recent boundary change" column in the table below.
All schools ranked by building utilization
Current enrollment as a percentage of PPS's own functional capacity from the 2021 Long-Range Facility Plan. Functional capacity accounts for classroom count, modular rooms, and set-asides (SPED, art/music, DLI co-location). This is a planning number from PPS, not a raw square-footage estimate.
Long-term sustainability: 7-year enrollment change (2018 → 2025)
Total in-scope enrollment fell 20% over this window (median school -19%). Bars below that baseline are losing students faster than the district overall. Source: NCES CCD fall 2018 + ODE fall 2025.
Housing growth forecast (Metro BLI, ~2035)
Projected new residential units inside each school's PPS attendance area, from Metro's 2045 Building Land Inventory (BLI) Housing-Employment Allocation grid. It's an area-weighted sum over intersecting BLI cells; schools without a published catchment (focus-option, alternative) fall back to a 1-mile buffer (shown in teal). Each bar below is one school, ranked by forecast growth. Source: Portland/Metro BLI Housing-Employment Allocation.
Seismic retrofit exposure (Holmes 2024)
Rough-order-of-magnitude cost to fully retrofit every building at each school, from the Holmes Engineering 2024 PPS Seismic Assessment. Bar color shows whether the remaining cost is funded: blue = covered by the 2025 bond, red = remaining cost not in any current bond. A purple-outlined bar indicates unreinforced-masonry (URM) buildings which is the highest seismic-risk category. A • prefix indicates schools that had prior targeted or full retrofit work from earlier bonds (2012/2017/2020). That history doesn't change whether the Holmes-estimated remaining cost is funded. Portfolio remaining exposure across the 74 in-scope schools: ~$800M.
Transportation impact: miles to nearest same-level alternative
Great-circle distance from each low-enrollment school to the nearest larger school of the same grade band (elementary, K-8, middle, alternative). A rough lower bound on how far families would have to travel if their school were closed; actual PPS reassignment may differ. Bars are labeled with the nearest alternative school.
Students per teacher (Fall 2023)
Fall 2023 NCES enrollment divided by fall 2023 classroom-teacher FTE — a same-year snapshot of how many students each full-time teacher is accountable for. Excludes counselors, social workers, nurses, and other non-instructional staff. The dashed line marks the in-scope median. Small alternative and K-8 programs naturally cluster low (fixed teacher-FTE floor spread across fewer students); larger neighborhood elementaries and middle schools cluster high. Source: NCES CCD 2023.
DLI vs. neighborhood enrollment at shared-building schools
Every Dual Language Immersion program is a strand hosted inside a neighborhood school; its students come from a district-wide lottery, not the catchment. This chart splits each host school's October 2025 headcount into mainstream/neighborhood (left) and DLI strand (right). Schools range from single-strand hosts (Lane 8% DLI) to whole-school immersion programs (Lent, Rigler, Richmond: 100%). Source: PPS Language Immersion Enrollment Report 2025-26.

Methodology & sources
Each of the 74 rows is one PPS school in the closure-announcement scope (elementary, K-8, middle, and alternative; PPS's 9 high schools are excluded per the March 10 announcement). Columns are pulled from the sources below and joined on a mix of NCES school ID, Oregon ODE School Institution ID, and manual name mapping for recent renamings (e.g., Madison → McDaniel, Wilson → Wells-Barnett, Fernwood → Beverly Cleary). Geographic indicators (affordable housing, permits) are aggregated to each school using its actual PPS attendance boundary, with a 1-mile haversine radius as a fallback for focus-option / alternative / embedded programs that don't have a published catchment.

Buildings & seismic
- PPS Long-Range Facility Plan (2021, Vol 1)
- Functional capacity per school (2021). PPS's planning number: gross capacity derived from classroom count and area, minus set-asides (SPED focus, art/music, computer lab, DLI co-location, etc.), with a configuration-specific utilization rate applied (85% at middle/high, higher at K-5/K-8) and further reductions at Title I and TSI/CSI schools.
- KPFF Seismic Report (2009)
- Year built, square footage, and construction type for every building in the district. Note: square footage predates recent bond expansions.
- Holmes Engineering Seismic Assessment (2024)
- Per-campus rough-order-of-magnitude (ROM) retrofit cost estimates for all ~80 PPS sites, plus URM classification and URM-only partial-retrofit cost. We parse the per-school "Complete Retrofit" ROM totals into
retrofit_cost_remaining_usd. Holmes excludes schools recently or near-completely modernized (shown at $0 in the chart). - PPS Bond: Seismic & modernization
- Retrofit and modernization status (full, targeted, planned under 2025 bond).
Ventilation & indoor air
- PPS Indoor Air Quality — airflow survey (2021)
- NEBB-certified per-room airflow tests (Amerseco + Neudorfer Engineers, 2021) published as one PDF per building. Measured total supply CFM, outside-air CFM, and derived ASHRAE Total Effective Air Changes per Hour (ACH_e) with and without portable filtration. We parse each PDF for room-level readings, then report per-building: rooms tested, median ACH_e without portable filters (the HVAC-only floor), the share of rooms below Lancet's 3 ACH lower bound and 6 ACH recommended classroom target, and whether a MERV-13 filter upgrade had been installed at test time. Coverage: 74 of 83 roster buildings; omitted schools (Benson, McDaniel, Kellogg, Alliance, Odyssey, ACCESS, Bridger Creative Science, Clark) were either newly-modernized after the survey or don't have a standalone building report.
Title I & federal programs
- PPS Funded Programs
- Title I-A schoolwide designations, 2025-26.
Specialized programs
- PPS Dual Language Immersion (DLI) program list

The only source that separates immersion students from neighborhood students inside a shared-building school; ODE Fall Membership reports only the combined total.
Housing & neighborhood growth
- Oregon Affordable Housing Inventory (OAHI)
- Existing and pipeline affordable housing projects with unit counts, bedroom mix, and status. Aggregated to each school using the school's PPS attendance boundary (point-in-polygon) rather than a fixed radius; schools without a published catchment (alternative, embedded, or focus-option programs) fall back to a 1-mile haversine radius.
- Portland BDS Residential Building Permits (via PortlandMaps)
- 4,144 permits issued 2022 – 2026-04 that created new residential units; 12,401 units total. Single-family, ADUs, and multifamily (market-rate and affordable combined). Attributed to each school by point-in-polygon against the PPS attendance boundary, with the same 1-mile fallback noted above.
- City of Portland School Attendance Areas
- PPS attendance-area polygons (elementary/K-8, middle, high), retrieved from the City of Portland
School_BoundariesFeatureServer layer and saved todata/raw/pps_boundaries_*.geojson.
Regional context (not attached per-school)
Metro Council's 2045 Distributed Forecast (Ord. 21-1457, adopted Feb 2021) projects City of Portland growing from 668,429 to 774,219 residents (+16%) by 2045, and unincorporated Multnomah County from 19,328 to 40,490 (+110%). Metro only publishes this forecast at city/county level (no tract or TAZ breakdown, and no age bands), so it is not attached to individual schools here; it is background only. PSU Population Research Center explicitly does not forecast Multnomah County, so Metro is the only public long-horizon population forecast for the PPS footprint.
Lowest-enrollment 15
A descriptive subset: the 15 in-scope schools with the lowest raw fall 2025-26 enrollment, surfaced in several views for context. This is not a PPS-published shortlist; the district is expected to release its own list in Nov 2026 with a board vote in Dec 2026.
Derived metrics
- Student-experience metrics (CRDC 2021)
- PPS doesn't publish a per-school "student experience" composite, and the obvious post-COVID source (Oregon's At-A-Glance "regular attenders %" and teacher-experience tables) isn't available as a clean bulk download. As a stand-in, three 2020-21 CRDC-derived rates are surfaced: support staff per 100 students (counselor + social worker + psychologist FTE ÷ 2020-21 enrollment × 100), chronic absenteeism rate (students chronically absent ÷ 2020-21 enrollment), and OSS per 100 (out-of-school suspension instances ÷ 2020-21 enrollment × 100; counts events, not unique students). Caveat: 2020-21 was the second pandemic year; chronic-absence rates were unusually high district-wide and should be read as a floor on current rates.
Caveats
Functional capacity is from the 2021 Long-Range Facility Plan and does not reflect post-2021 bond work or reconfigurations (Harrison Park's conversion to a middle school, Lincoln's rebuild, etc.). Building square footage is from 2009 and may understate capacity at schools expanded under recent bonds. CRDC LEP/IDEA counts are from 2020 (COVID year) and are divided by 2025-26 enrollment to derive shares; treat as approximate. Free/reduced meal shares use 2022 counts over 2022 enrollment; post-2022 trends are not reflected. Permits represent approvals, not completions; a permit may be issued but not built.
