Subject: Airport Conflict Evaluation
Hamstra Crossing
Northwest Corner of McQueen and Germann Roads
Recommendation
Staff recommends the Airport Commission ("Commission") present an Airport Conflict Evaluation (ACE)
report to the Zoning Administrator and City Council with a finding of "no conflict with airport uses" for the
proposed Hamstra Crossing development at the northwest corner of McQueen Road and Germann Road.
Background
The project is a two-phase development consisting of a gas station/convenience store, a car wash, and
four recreational vehicle storage buildings at the northwest corner of Germann Road and McQueen Road
(Exhibit A - Vicinity Map, Exhibit B - Property Location). The property is zoned Planned Area Development.
The site is approximately one half mile (0.5) of a mile to the northwest of the Airport property line (Exhibit
A- Vicinity Map, Exhibit B- Property Location).
The six buildings will consist of approximately 102,821 square feet (SF) of building space plus fuel and car
wash canopies (Exhibit C - Site Plan). The proposed heights will not exceed thirty-two (32) feet.
The 2021 Chandler Airpark Area Plan (CAAP) designates the property as Innovation (Exhibit D – Chandler
Airpark Area Plan Land Use Plan).
Analysis and Stipulations
Retail, commercial and industrial land uses are generally compatible with airport operations. The
property will experience daily overflights from aircraft on takeoff and landing (Exhibit E – Flight Tracks).
Based on the proposed building heights, the proposed development does not appear to pose a hazard to
flight safety or be an airspace obstruction. The proposed building height does not appear to impact the
approach and departure surfaces for either runway. Final building structures, including all rooftop objects,
must not impact the approach and departure surfaces for the Airport’s runways.
The owner/applicant must file a Notice of Proposed Construction (FAA Form 7460-1) with the Federal Aviation
Administration (FAA) for the final structure heights, including, without limitation, all rooftop antennas,
parapets, light poles, and other equipment. The form may be submitted online at the FAA’s Obstruction
Evaluation/Airport Airspace Analysis (OE3A) website. The FAA-assigned numbers for all evaluation cases
must be provided to Airport Administration.
The owner/applicant must ensure that its contractors file a Notice of Proposed Construction (FAA Form 7460-1)
with the FAA for temporary construction equipment including, without limitation, cranes, drilling rigs,
concrete boom pumps and other vertical equipment. The form may be submitted online at the FAA’s
Obstruction Evaluation/Airport Airspace Analysis (OE3A) website. The FAA-assigned numbers for all
evaluation cases must be provided to Airport Administration.
It is strongly recommended that the owner/applicant ensures its contractor(s), submits the 7460-
1 form for the construction equipment as soon as possible before construction, allowing for a
minimum of sixty (60) calendar days before start of vertical work.
The owner/applicant and its contractors must coordinate directly with Airport Administration at
least thirty (30) calendar days before starting vertical construction.
The proposed project does not indicate the use of rooftop solar panels. If solar panels are anticipated to
be installed, the owner/applicant must complete a solar study and coordinate with Airport Administration
to ensure that glare will not interfere with aircraft on approach or takeoff.
The proposed project’s building design must not create reflectivity issues with aircraft in the traffic
pattern and on approach or takeoff (Exhibit F – Building Elevations). The use of non-reflective glazing and
non-reflective paint is encouraged.
