RE: TD-DEV-0625-00172, West Coast Data Center and Future Building, 1151 E Hermans Rd,
Bldg 919, Tucson, AZ. 85756, Received July 9, 2025
To whom this may concern,
Thank you for the opportunity to comment on TD-DEV-0625-00172, the development plan for a
two new buildings. This development is located in the S.W. quarter and the S.E. quarter of
Section 19, Township 15S, Range 14E, of the Gila and Salt River Meridian. The development
site occupies parcel numbers 140-43-013B and 140-43-013D, covers approximately 8.427 ±
acres, and is zoned as Heavy Industrial Zone (I-2). The nearest major roadway intersection is
South Nogales Highway and East Hermans Road, approximately 1000 feet to the southeast of
the subject development.
This site does lie within FAA Part 77 airspace.
Below are the responses the FAA Pre-Screening Tool generated for this project:
1. Based on the information you provided, you are required to file notice with the FAA. You
must submit notice at least 45 days before the start of the proposed construction or
alteration or the date an application for a construction permit is filed, whichever is
earliest.
2. Note: If you propose construction or alteration that is subject to the licensing
requirements of the Federal Communications Commission (FCC), you must submit
notice to the FAA on or before the date that an application is filed with the FCC. Visit
FCC Licensing to learn more.
The Tucson Airport Authority is requiring a resubmittal of this project to include the below
condition.
1. “According to the Federal Aviation Administration (FAA) Pre-Screening Tool, this project
area is located on an airport. As this project develops, all applicants must file FAA Form
7460 with the FAA at least 45 days before construction activities begin unless FAA staff,
with the Obstruction Evaluation / Airport Airspace Analysis (OE/AAA), provides the
project applicant with written communication that filing FAA Form 7460 is not required. It
is highly recommended that the applicant file earlier than 45 days to provide the
applicant with sufficient time to respond to any concerns identified by the FAA. Note also
that cranes to be used during all development or construction activities must also be
identified with Form 7460. Please file Form 7460 at
https://oeaaa.faa.gov/oeaaa/external/portal.jsp.”
Please do not hesitate to contact me if you have any questions or concerns regarding this
comment letter. I can be reached by email at srobidoux@flytucson.com or by telephone at 520-
