Mr. Walford:
The Miami -Dade Aviation Department has reviewed the proposal dated November 1, 2004 for the Lynx structure
located at the SE corner of South Miami Ave and SE 2nd ST. Our review finds that the referenced structure at 610 ft
Above Mean Sea Level conforms to the Miami -Dade County Height Zoning Ordinance.
This height determination is an estimate issued on a preliminary or advisory basis. For a more accurate determination,
you may re -submit this information to us by providing latitude and longitude coordinates of the footprint of the
proposed structure in "degrees, minutes, seconds" format using a NAD83 projection with an accuracy of three decimal
places (for the `seconds' number).
The proposed building height requires the applicant to file with the FAA form 7460-1, `Notice of Proposed
Construction Alteration for Determination of Known Hazards', in addition, construction cranes for this project
exceeding 200 ft in height must be filed by the construction contractor using the same form. Thus, FAA form 7460-1
be filed twice, once for the structure and once for the construction cranes. The form is available through this
agree or through the FAA website: http://forms.faa.gov/forms/faa7460-1.pdf. This form should be mailed to: Southern
Regional Office, Air Traffic Division, ASO-520, 1701 Columbia Avenue, College Park, GA 30337.
Please note that the airspace review and approval process is governed by two different regulations: the Miami -Dade
County Height Zoning Ordinances and Federal Regulation Title 14 Part 77. Neither MDAD nor any MDAD staff has
the power or authority to enforce the County's zoning provisions or the FAA requirements. The County's Department
of Planning & Zoning (P&Z) enforces the County's height zoning provisions (Section 33-340) which states that "all
applications for permits made to appropriate municipal Building and Zoning Departments or agencies for all
construction... shall be approved by the [Miami -Dade Department of Planning and Zoning] Director and the Building
Official or by their duly authorized representatives prior to issuance of the permit." The FAA has its own airspace
evaluation requirements, as well as the right to permit or not permit construction of a facility or use of a crane based on
the particular facts then presented before the FAA. Only P&Z can make the final determination as to whether the
County's zoning requirements and height limitations are met, and only FAA can make the determination as to whether
FAA building and height requirements are met.
As the permit -issuing agency, you are reminded that no final approval or building permit should be issued until the City
of Miami has in its possession a copy of the FAA "Determination of No Hazard" for this structure. Your agency must
assure that no point of this structure is constructed higher than the lower (more restrictive) of either 1.) The FAA
`Determination of No Hazard' height or 2.) A maximum height as stated by the Miami -Dade County Height Zoning
Ordinance.
Similarly, the City of Miami has the responsibility to ascertain that the proposed crane height is not a danger to aviation
•gation by confirming that the proposed crane height does not exceed the height stated by the FAA on the
11/29/2004
rage GU1L
"Determination of No Hazard" for the crane and that the crane is properly flagged, lighted, and otherwise marked
•rdin to FAA standards.
This determination is based, in part, on the description provided to us by the City of Miami, which includes specific
building locations and heights. Any changes in building locations/layouts or heights will void this determination. Any
future construction or alteration, including an increase to heights requires separate notice to the FAA and the Miami -
Dade Aviation Department.
Should the applicant have any questions in obtaining and/or filling out FAA form 7460-1 or if I can be of any further
assistance, please feel free to contact me at 305-869-3834.
Respectfully,
Daryl Vreeland
