** DETERMINATION OF NO HAZARD TO AIR NAVIGATION **
The Federal Aviation Administration has conducted an aeronautical study under the provisions of 49 U.S.C.,
Section 44718 and if applicable Title 14 of the Code of Federal Regulations, part 77, concerning:
Structure:Building Renton Commons
Location:Renton, WA
Latitude:47-28-50.16N NAD 83
Longitude:122-12-44.00W
Heights:33 feet site elevation (SE)
78 feet above ground level (AGL)
111 feet above mean sea level (AMSL)
This aeronautical study revealed that the structure would have no substantial adverse effect on the safe
and efficient utilization of the navigable airspace by aircraft or on the operation of air navigation facilities.
Therefore, pursuant to the authority delegated to me, it is hereby determined that the structure would not be a
hazard to air navigation provided the following condition(s) is(are) met:
As a condition to this Determination, the structure is to be marked/lighted in accordance with FAA Advisory
circular 70/7460-1 L Change 1, Obstruction Marking and Lighting, red lights - Chapters 4,5(Red),&12.
Any failure or malfunction that lasts more than thirty (30) minutes and affects a top light or flashing obstruction
light, regardless of its position, should be reported immediately to (877) 487-6867 so a Notice to Airmen
(NOTAM) can be issued. As soon as the normal operation is restored, notify the same number.
It is required that FAA Form 7460-2, Notice of Actual Construction or Alteration, be e-filed any time the
project is abandoned or:
__X__ At least 10 days prior to start of construction (7460-2, Part 1)
__X__ Within 5 days after the construction reaches its greatest height (7460-2, Part 2)
See attachment for additional condition(s) or information.
The structure considered under this study lies in proximity to an airport and occupants may be subjected to
noise from aircraft operating to and from the airport.

This determination expires on 04/02/2019 unless:
(a)the construction is started (not necessarily completed) and FAA Form 7460-2, Notice of Actual
Construction or Alteration, is received by this office.
(b)extended, revised, or terminated by the issuing office.
(c)the construction is subject to the licensing authority of the Federal Communications Commission
(FCC) and an application for a construction permit has been filed, as required by the FCC, within
6 months of the date of this determination. In such case, the determination expires on the date
prescribed by the FCC for completion of construction, or the date the FCC denies the application.
NOTE: REQUEST FOR EXTENSION OF THE EFFECTIVE PERIOD OF THIS DETERMINATION MUST
BE E-FILED AT LEAST 15 DAYS PRIOR TO THE EXPIRATION DATE. AFTER RE-EVALUATION
OF CURRENT OPERATIONS IN THE AREA OF THE STRUCTURE TO DETERMINE THAT NO
SIGNIFICANT AERONAUTICAL CHANGES HAVE OCCURRED, YOUR DETERMINATION MAY BE
ELIGIBLE FOR ONE EXTENSION OF THE EFFECTIVE PERIOD.
This determination is subject to review if an interested party files a petition that is received by the FAA on or
before November 01, 2017. In the event a petition for review is filed, it must contain a full statement of the
basis upon which it is made and be submitted to the Manager, Airspace Policy & Regulation, Federal Aviation
Administration, 800 Independence Ave, SW, Room 423, Washington, DC 20591.
This determination becomes final on November 11, 2017 unless a petition is timely filed. In which case, this
determination will not become final pending disposition of the petition. Interested parties will be notified of the
grant of any review. For any questions regarding your petition, please contact Airspace Regulations & ATC
Procedures Group via telephone -- 202-267-8783 - or facsimile 202-267-9328.
This determination is based, in part, on the foregoing description which includes specific coordinates, heights,
frequency(ies) and power. Any changes in coordinates, heights and frequencies or use of greater power, except
those frequencies specified in the Colo Void Clause Coalition; Antenna System Co-Location; Voluntary Best
Practices, effective 21 Nov 2007, will void this determination. Any future construction or alteration, including
increase to heights, power or the addition of other transmitters, requires separate notice to the FAA. This
determination includes all previously filed frequencies and power for this structure.
This determination does include temporary construction equipment such as cranes, derricks, etc., which may be
used during actual construction of the structure. However, this equipment shall not exceed the overall heights as
indicated above. Equipment which has a height greater than the studied structure requires separate notice to the
FAA.
This determination concerns the effect of this structure on the safe and efficient use of navigable airspace
by aircraft and does not relieve the sponsor of compliance responsibilities relating to any law, ordinance, or
regulation of any Federal, State, or local government body.
This aeronautical study considered and analyzed the impact on existing and proposed arrival, departure, and
en route procedures for aircraft operating under both visual flight rules and instrument flight rules; the impact
on all existing and planned public-use airports, military airports and aeronautical facilities; and the cumulative
impact resulting from the studied structure when combined with the impact of other existing or proposed
structures. The study disclosed that the described structure would have no substantial adverse effect on air
navigation.

1. LOCATION OF PROPOSED CONSTRUCTION
This proposal is for a 78-foot AGL (111-foot AMSL) residential building to be located at 215 Whitworth
Avenue in Renton, WA. The building will be approximately 1948 feet (0.32 nm) south-southeast of the RWY
34 threshold at Renton Municipal Airport (RNT), WA. The RNT airport elevation is 32 feet AMSL.
Renton Municipal Airport is served by a single runway, aligned 16/34. Runway 16 is a non-precision
instrument runway with three instrument approach procedures available: the RNAV (GPS) Y RWY 16, the
RNAV (GPS) Z RWY 16, and the NDB RWY 16. Runway 34 is currently a visual-only runway, but there is a
plan on file with the FAA to upgrade it to a non-precision instrument runway in the future.
To facilitate the public comment process, the 11 points of the building filed for evaluation are being circularized
under Aeronautical Study Number 2017-ANM-2900-OE, which is the tallest northwest corner of the building
and the point having the greatest impact on RNT Part 77 airspace surfaces. All comments received from this
circularization will be considered in completing the separate determinations for each of the points filed for the
building. The Aeronautical Study Numbers, coordinates, and heights for these 11 points are:

2. OBSTRUCTION STANDARDS EXCEEDED
The structure is identified as an obstruction under the following Part 77 standard:
a. Section 77.17.(a)(3): A height within a terminal obstacle clearance area, including an initial approach
segment, a departure area, and a circling approach area, which would result in the vertical distance between any
point on the object and an established minimum instrument flight altitude within that area or segment to be less
than the required obstacle clearance. This building would have the following effect on IFR operations at RNT:
RWY 16: Penetrates the 40:1 instrument departure slope in the initial climb area (ICA) by 31 feet, requiring a
TAKE-OFF MINIMUMS AND (OBSTACLE) DEPARTURE PROCEDURE, NOTE: RWY 16, building 1922
feet from departure end of runway, 312 feet left of centerline, 78 feet AGL, 111 feet MSL.
Page 5 of 8
b. Section 77.19(d): The approach surface area designated under 77.19 to protect aircraft during the final
approach phase of flight. While the proposed building would not penetrate the approach surface to the current
visual-only RWY 34, the various points on the building would exceed the RNT proposed (plan on file) 34:1
non-precision instrument Runway 34 approach surface area by the following amounts:
2017-ANM-2898-OE Penetrates by 21 feet.
2017-ANM-2899-OE Penetrates by 20 feet.
2017-ANM-2900-OE Penetrates by 28 feet.
2017-ANM-2902-OE Penetrates by 28 feet.
2017-ANM-2904-OE Penetrates by 20 feet.
2017-ANM-2905-OE Penetrates by 26 feet.
2017-ANM-2906-OE Penetrates by 26 feet.
2017-ANM-2907-OE Penetrates by 18 feet.
2017-ANM-2908-OE Penetrates by 18 feet.
2017-ANM-2909-OE Penetrates by 18 feet.
2017-ANM-2910-OE Penetrates by 18 feet.
3. EFFECT ON AERONAUTICAL OPERATIONS
a. The impact on arrival, departure, and en route procedures for aircraft operating under VFR: The proposed
structure would exceed the RNT proposed (plan on file) RWY 34 Part 77 approach surface by 18 to 28 feet.
b. The impact on arrival, departure, and en route procedures for aircraft operating under IFR: The proposed
structure would penetrate the RWY 16 40:1 instrument departure surface in the ICA by 31 feet, requiring a
note in the TAKE-OFF MINIMUMS AND (OBSTACLE) DEPARTURE PROCEDURES to alert pilots of the
building's presence.
c. The impact on all planned public-use airports and aeronautical facilities: None.
d. The cumulative impact resulting from the proposed construction or alteration of a structure when combined
with the impact of other existing or proposed structures: None.
4. CIRCULATION AND COMMENTS RECEIVED
The proposal was circulated for public comment on 16 August 2017. The public comment period ended on 22
September 2017, and no responses were received as of that date.
5. DETERMINATION - NO HAZARD TO AIR NAVIGATION
It is determined that the proposed construction would not have a substantial adverse effect on the safe and
efficient use of navigable airspace by aircraft.
6. BASIS FOR DECISION
Part 77 establishes standards for determining obstructions to air navigation. A structure that exceeds one or
more of these standards is presumed to be a hazard to air navigation unless the obstruction evaluation study
determines otherwise. Just because a proposed structure exceeds a Part 77 surface does not automatically make
it a hazard. In this case, the proposed structure would exceed the RNT proposed (plan on file) RWY 34 Part 77
34:1 instrument runway approach surface by 18 to 21 feet. It would also penetrate the RWY 16 40:1 departure
surface in the ICA by 31 feet. However, the proposed building would not require an increase to the minimum
instrument departure climb gradient or weather minimums, and will have no effect on current or proposed
instrument approach procedures at RNT. Further, no VFR issues were raised with regard to the penetration of
Page 6 of 8
the proposed RWY 34 Part 77 approach surface. The incorporation of obstruction lighting will mitigate the
Part 77 surface penetration.
NOTE: This building will be located in very close proximity to the final approach path for RWY 34, and the
departure path for RWY 16 at Renton Municipal Airport. Occupants will be exposed to frequent jet and piston-
engine aircraft noise and the sight of aircraft ranging in size from helicopters to large jet airliners operating at
low altitudes overhead and near the building.
Any cranes used in the construction of this building will require separate aeronautical studies.
