RESOLUTION NO. 89-115
RESOLUTION RECOMMENDING REVISED PROCEDURES FOR THE EAGAN/MENDOTA
HEIGHTS CORRIDOR TO REFLECT CHANGES SINCE THE CORRIDOR WAS FIRST
IMPLEMENTED AND PROVIDING A MORE EQUITABLE DISTRIBUTION OF
AIRCRAFT NOISE BETWEEN THE CITIES OF MENDOTA HEIGHTS AND EAGAN
WHEREAS, when the Corridor was established, Runway 11L-29R was a
short runway used primarily for propeller aircraft with little or
no air carrier jet departures, and,
WHEREAS, the term "Corridor" is a misnomer since only a southern
boundary has been formally defined while the northern "boundary"
has continued to move north over time, and
WHEREAS, changes in magnetic declination to the north have placed
flight tracks further to the north each year, and
WHEREAS, forecast increases in airport operations will eventually
overwhelm the corridor and long-range planning appears to be
prudent, and
WHEREAS, the noise contour reflecting hourly departures (in terms
of L10) has continued to move to the north beyond the
Metropolitan Council's policy contour, and
WHEREAS, Runway 11L now takes an equal share of departures
although there is less demand for turns to the north, and,
WHEREAS, peak arrivals and departures are more intense under the
airline hubbing concept than in the past, and
WHEREAS, this leads to required divergence of aircraft departing
the parallel runways and with the southern boundary fixed, this
forces aircraft further north, and,
WHEREAS, realignment of the primary instrument runway at St. Paul
increases potential conflicts with MSP eastbound departures, and,
WHEREAS, the PRS (Preferential Runway System) as revised by the
new Runway Use System places greater emphasis on use of the
Corridor for departures which leads to an increase in divergent
tracks within the corridor and hence over Mendota Heights;
NOW, THEREFORE BE IT RESOLVED BY THE CITY COUNCIL OF THE CITY OF
MENDOTA HEIGHTS, MINNESOTA, that the following changes in
aircraft operations within the Eagan/Mendota Heights Corridor be
submitted to the Metropolitan Aircraft Sound Abatement Council
for evaluation and implementation:
PROPOSED EAGAN/MENDOTA HEIGHTS CORRIDOR SYSTEM
1. A"15° Corridor" shall be defined on the north as a
magnetic bearing of 105° from the southeast end of Runway
11L/29R and on the south as a magnetic bearing of 120°
from the southeast end of Runway 11R/29L. The final
placement of the 15° Corridor shall be determined by the
Metropolitan Aircraft Sound Abatement Council Operations
Committee.
2. The 15° Corridor shall be given first priority for
departures from Runways 11R and 11L whenever traffic
volumes permit.
3. A"Fanned Corridor" shall be defined on the north as a
magnetic bearing of 090° from the southeast end of Runway
11L/29R and on the south as a magnetic bearing of 150�
from the southeast end of Runway 11R/29L.
4. Use of the "Fanned Corridor" shall not be permitted
between the hours of 10:00 p.m. and 7:00 a.m. (2200 to
0700 local time).
5. The MSP Tower shall determine when peak departure periods
require use of the "Fanned Corridor." The peak departure
periods shall not exceed an aggregate maximum of 8 hours
per day between 7:00 a.m. and 10:00 p.m.
6.
7.
The boundaries of the 15° Corridor shall be depicted on
radar video maps.
A Corridor System 180-day test shall be conducted to
answer the following questions:
a) Does the Corridor System lead to a more equitable
distribution of noise between Mendota Heights and
Eagan? .
b) Is the Corridor System operationally feasible?
Adopted by the City Council of the City of Mendota Heights this
Third day of October, 1989.
