Compatibility Assessment
Maxwell AFB has engaged the local businesses in the southern APZs to
educate them on the impacts that the cranes can have on aviation, and to
encourage them to obtain FAA waivers for the cranes prior to beginning
construction activities. The businesses have started putting flags on the
cranes, but there is no formal procedure for notifying Maxwell AFB in order
to provide them with time to assess potential impacts to aircraft operations
prior to bringing in construction cranes.
FAR Part 77.9 is an FAA Rule that provides guidelines for notifying the FAA of
construction or alterations for projects which:
Exceed 200 feet above ground level (AGL);
Evaluation / Airport Airspace Analysis (OE/AAA), which can be done
electronically at http://oea.faa.gov. This information is not included in the
city’s zoning ordinance and nor are copies provided at the city’s planning
office. In addition, this form is not required upon submitting a package to
the land use planning office in the city.
According to the City of Montgomery’s Zoning Ordinance, temporary cranes
are not regulated and do not require permits for submission of plans that
involve construction activities. In addition, the AHA overlay does not require
coordination with the installation regarding use of temporary cranes in this
area.
Findings
Are within 20,000 feet of a public or military airport which
exceeds a 100:1 surface from any point on the runway with at
least one runway that is more than 3,200 feet.;
Are within 10,000 feet of a public or military airport which
exceeds the 50:1 surface from any point on the runway with the
longest runway no more than 3,200 feet in length.
Notifications are required to be filed at least 45 days prior to the proposed
construction start date for permanent and temporary obstructions.
Temporary obstructions include:
construction equipment;
cranes, boom trucks;
concrete pumps;
drilling rigs;
stock piles; and
temporary lights.
Local businesses are not required to communicate or coordinate with
Maxwell AFB about construction activities that occur within the AHA.
The city does not require a copy of the FAA’s Form 7460‐1 to be
submitted
