A home several miles from the end of Luke Air Force Base's runway can come with a military airport disclosure. Meanwhile, a 160-acre parcel about a mile north of the base is set to go before the Glendale City Council on Oct. 27 as a proposed campus of three data centers and a gas generation plant. Both outcomes come from lines written into Arizona statute. The line with the most influence on what gets built near the base was drawn from 1988 noise contours, decades before the first F-35A arrived.
For anyone comparing homes along the Loop 303 corridor, Citrus Road, or Olive and Bethany Home, those lines say more about the next ten years of the area than the sound of today's flights does.
The disclosure arrives before anyone checks the map
A west Glendale buyer usually runs into Luke first through paperwork. Under A.R.S. 28-8484, from and after December 31, 2006, a seller of residential real estate must give the buyer a written disclosure before title transfers if the property sits in "territory in the vicinity of a military airport," as shown on a map prepared by the State Land Department. New subdivisions carry the same statement in their public reports and in any lot reservation or conditional sales contract signed before a public report is issued.
The vicinity zone is large. A.R.S. 28-8461 defines it for Luke as 10 miles north, south and west of the main runway centerline, and 4 miles east. The same statute defines a separate, much smaller "high noise or accident potential zone." That zone uses the 1988 Maricopa County noise contours plus two accident potential zones. At Luke, accident potential zone two runs 30,000 feet southwest from the end of each runway, double the 15,000-foot standard used elsewhere.
Under these definitions and the planning rules in A.R.S. 28-8481, each line does a different job:
| Line | What defines it | What it triggers |
|---|---|---|
| Territory in the vicinity | 10 miles N/S/W, 4 miles E of the runway centerline | Seller's written disclosure; public report language; sound attenuation standards in local building codes |
| High noise contours | 1988 Maricopa County noise contours, 65 Ldn and up | Compatible general plans and zoning; variances need a specific finding that military airport compatibility is preserved |
| Accident potential zones | Zones off the runway ends, with Luke's zone two extending 30,000 feet southwest | The same compatible planning and zoning duty as the high noise zone |
The disclosure tells a buyer that a home falls inside the outer box, and nothing more. It doesn't say whether the home sits under a contour. Maricopa County's 2024 file for Village @ Waddell, a proposed 221-lot subdivision at the northwest corner of Citrus Road and Bethany Home Road, shows the gap: the site is inside the military airport vicinity but outside the 65-Ldn contour. Buyers there get the same disclosure as buyers much closer in, even though the planning rules that apply to them are lighter.
The contour was drawn for F-16s and still governs in the F-35 era
The noise contours with legal force are old. Glendale's Envision Glendale 2040 General Plan ties its Luke Compatible Land Use Area to the 1988 AICUZ 65 Ldn contour. In an August 2024 explainer, Luke Air Force Base describes its noise contours as running from 65 to 80 day-night average sound level and identifies the 65 line as the outermost.
The aircraft themselves changed completely. The Air Force's June 2012 F-35A training basing environmental impact statement found that at its study point, Cotton Lane Community Church, an F-35A was about 6 dB louder than the F-16C on a typical non-afterburner departure, about 9 dB louder in traffic pattern flight, and about 15 dB louder on arrival.
The same study's modeled contours didn't simply grow to match:
| 2012 EIS scenario | Off-base people above 65 DNL | Off-base acres above 65 DNL |
|---|---|---|
| Baseline conditions | 1,601 | 7,042 |
| 72 F-35As | 1,181 | 7,916 |
| 144 F-35As | 5,340 | 11,651 |
DNL averages sound over a full day and night, so a contour reflects how many flights happen and where they go, along with how loud each one is. The 72-jet scenario covered more acres and fewer people than the baseline. Under the 2013 Record of Decision, the Air Force added another 72 F-35As, for a planned total of 144 by calendar year 2023. These figures are 2012 models, not 2026 measurements. Even so, the statute kept its 1988 definition through every one of these changes.
The contour sets lot sizes west of Loop 303
The 1988 line has its most concrete effect on residential density. Luke's Graduated Density Concept, as laid out in Glendale's Allen Ranches PAD, caps housing at 2 dwelling units per acre from the 65-Ldn contour out to half a mile, and at 4 units per acre from half a mile to one mile.
Allen Ranches shows how a developer plans around those caps. The roughly 865-acre property runs from the southwest corner of Bethany Home Road and Loop 303 south to Camelback Road and west to Citrus Road. Its eastern 498 or so acres sit within the 65 and 70 Ldn contours. The county had already approved 734 single-family homes at 2.0 units per acre on the western 367 acres. The May 2020 Glendale proposal moved the homes farther west onto about 250 acres, put industrial uses on roughly 615 acres beside the freeway, and placed a landscaped drainage channel between the two. In 2020 the land was unincorporated county within Glendale's planning area, and an annexation application was being processed with the PAD.
So the larger lots near Citrus Road and the warehouses near the 303 come from the same 1988 line, applied with distance-based caps.
Land inside the contour becomes industrial
Housing is capped near the line, and inside the higher contours it is largely kept out. Glendale's recent filings form a ring of non-residential projects:
- Bethany 303, at the northeast corner of Sarival Avenue and Claremont Drive, lies within the 75 and 80 DNL contours and was approved by ordinance in April 2020.
- West 303 Crossing, at the northeast corner of Sarival and Maryland avenues, about half a mile east of Loop 303, sits within the 70 and 75 DNL contours.
- Reems & Myrtle is a 9.4-acre industrial PAD at the northwest corner of Myrtle Avenue and Reems Road, about half a mile southeast of Luke, inside the 70 to 75 LDN contour. Its November 2025 narrative excludes residential uses.
- Project Eagle, the 160 acres west of the northwest corner of Litchfield Road and Olive Avenue, is the largest. According to the Glendale Star, it would hold three data centers totaling 1.1 million square feet and a gas generation plant. The land sits within Luke's noise contours and carries Glendale's Luke-compatible land use designation.
The Project Eagle hearing shows what this means for nearby homes. The Glendale Star reported that a Waddell resident who said he lives 2,000 feet from the site told council:
"The proposed PAD relies primarily on 75-foot setbacks, 6-foot-high walls and limited landscaping as a transition for this massive industrial campus."
The project's attorney told council the proposal includes a block wall at least 8 feet high along parts of the site. In the same Glendale Star account, Vice Mayor Ray Malnar noted the large distance between the property and the next land available for residential development. The attorney answered that statutory, General Plan and zoning limits govern what can be built around the site. The applicant's July 2026 PAD narrative recommends sound attenuation and occupant notification and cites an estimate of about 170 overflights per day. No final decision was made at that hearing. The annexation and rezoning are expected back before council on Oct. 27.
Flights can change while the legal line stays put
The last U.S. F-16 training mission at Luke ended in September 2024, according to Air Education and Training Command. At the time it reported five F-35 squadrons flying and projected two more over the next two years. A September 2024 base noise explainer put weekday flights at 100 to 150, generally between 7 a.m. and 11:30 p.m. It also said seasonal wind direction can change which neighborhoods hear more noise.
There have been organizational changes since then. On July 17, 2026, the 56th Fighter Wing moved from Air Education and Training Command to Air Combat Command, and Col. Nicholas Ihde took command from Brig. Gen. David Berkland, the Glendale Star reported. The FAA's Phoenix-area airspace proposal would add satellite-based routes coordinating Glendale, Goodyear, Buckeye and Luke airspace. The Glendale Star's coverage said no final decision had been made and estimated implementation in early 2027.
None of these changes redraws the 1988 contour in statute. The density caps and industrial zoning described above stay on the same geography whatever the flight schedule does.
What to check before writing an offer
- Locate the parcel against the contour lines. The Arizona State Land Department keeps a Luke Air Force Base airfield layer with the 65, 70, 75 and 80 LDN lines. It lists its data as updated December 15, 2025.
- Read the disclosure as a boundary statement. Being in the vicinity zone and being under a contour are separate facts. The Arizona Department of Real Estate's airport boundary maps page is the state's starting point for that registry.
- Look at the vacant land between the home and the base. Glendale's General Plan land use map shows where Luke-compatible designations apply, though the city warns its maps are not the final authority on parcel zoning.
- Follow the pending cases. Project Eagle's Oct. 27 return to council is the next big one. Filings for nearby parcels show what the land next to a subdivision is planned to become.
- Visit the home more than once. The base's own explainer says wind direction changes where the noise falls, so one afternoon visit may not represent the rest of the year.
Sellers in these areas face the same question from the other direction. Our Glendale home selling checklist covers the paperwork side, and our Glendale neighborhood page covers the rest of the city.
