FAA Airspace Compliance

The FAA requires notification for any tower construction or alteration of any FCC registered antenna structure. Waterford's streamlined and efficient web portal facilitates quick and accurate site evaluation by Waterford or the customer, as well as FAA form certification and filing services on any structure that requires FCC regulatory notification and compliance.

Sample SAR Reports

FAA filing and certification services offered:
  • Search Area Ring Analysis (SAR)
  • 1A/2C Survey
  • 7460-1, 7460-2 Part 1, 7460-2 Part 2
  • 854/854R Antenna Site Registration (ASR)

If you're interested in a scheduling a demonstration of Waterford's easy-to-use customer portal for the purpose of completing your own FAA site evaluations, please contact your Waterford representative today.

Airspace Study (aka TERPS Analysis)

Notification to the FAA is required for any tower construction or alteration of an antenna that is registered with the commission. Towers that meet certain height and location criteria (generally tower >200’ above ground level or located near an airport) require notice to the FAA and registration with the FCC. Waterford can complete an Airspace Study (aka TERPS Analysis) to quickly and efficiently determine if a proposed construction meets FAA notification and FCC registration requirements; however proposed antenna structure owners (applicants) must still file a Notice of Construction (see FAA Form 7460-1 below) with the FAA to obtain a formal “No Hazard” determination.

1A/2C Survey

Wireless communication companies and tower owners are required by the Federal Aviation Administration (FAA) to submit 2C or 1A Certifications for sites where towers or antennas are installed or are planned to be installed. Certification includes surveying using GPS to determine the latitude and longitude of the tower or structure along with elevations of the tower, structure and installed or proposed antennas.

The 1A and 2C certifications refer to land survey accuracy. An FAA 1A certification is +20 ft horizontally, +3 ft vertically. An FAA 2C certification is +50 ft horizontally, +20 ft vertically.  You do not need an official form, but Waterford will provide a certificate stating that the cell tower survey we performed is within the required accuracy range. This is known as an FAA 1A letter or an FAA 2C letter.

7460-1, 7460-2 Part 1, 7460-2 Part 2

FAA notification for a proposed new structure or for alterations to an existing structure requires the preparation of FAA Form 7460-1 . Following FAA and all other regulatory approvals, you will be required to submit, a minimum of 48 hours before construction begins, FAA Form 7460-2, a supplemental notice identifying when construction will begin. Another supplemental notice is required to be filed when the structure has reached its greatest height.

FAA 7460-1
The FAA requires this Notice of Proposed Construction or Alteration form to be filed for
almost every new build or change to an existing tower.

FAA 7460-2
The FAA requires this Supplemental Notice of Proposed Construction or Alteration form to be filed a minimum of 48-hours prior to construction start.

FAA 7460-2 Part 1
The FAA requires a Notification and Completion to be filed for any structure over 200ft or when in other specific circumstances.

FAA 7460-2 Part 2
The FAA requires a Cancellation Notice form to be filed for every 7460-1 in the case when it is decided that the towers will not be built as planned or when a previously registered structure is removed.

854/854R Antenna Site Registration

Once applicants obtain a No Hazard Determination from the FAA, the ASR requires applicants to submit the FAA’s study number, along with FCC Form 854, to the Commission. The Commission then verifies with the FAA the accuracy of the marking and lighting specifications provided by the applicant.  If the Commission accepts the application, it issues an ASR form (Form 854R), which typically incorporates the FAA’s “no hazard” marking and/or lighting specifications and assigns the antenna an ASR number.  Once an antenna structure is registered, its owner must ensure that the structure complies with all of the relevant FAA chapters specified on the registration, or the owner may be subject to Commission enforcement action.  No changes to the specifications in the ASR are permitted without prior approval from both the FAA and the Commission; owners seeking to change an antenna structure’s specifications must first seek FAA approval, and only then may they file a request with the Commission to modify the ASR.  Prior to changing the marking or lighting on the structure, antenna structure owners must receive a modified ASR form from the Commission incorporating the change.  Once the antenna structure or tower is constructed or altered, the owner must then file FAA Form 7460-2, Notice of Completion of Construction or Alteration, with the FAA, and FCC Form 854 with the FCC notifying both agencies that the construction has been completed.


A Notice to Airmen (NOTAM) is a notice filed with the FAA to alert aircraft pilots of potential hazards along a flight route or at a location that could affect the safety of the flight.  A common occurrence in the communications tower industry, when a tower structure is not properly lit because of a light outage, the tower owner is required to notify the FAA. Doing so creates a Notice to Airmen (NOTAM) that is available to all pilot in regularly published notices and also through the FAA's NOTAM phone service.  Waterford can complete this notification process quickly and efficiently.
