The contents of this letter are to be distributed to all of the •
following :
1 . Weld County Commissioners
2. Weld County Council
3 . City of Greeley City Council
4. Greeley-Weld County Airport Authority
Recently both the City Council and the County Commissioners voted to
support a proposed plan to expand and re-align the existing configura-
tion of the Greeley-Weld County Airport. This decision has resulted
in a study by users of the airport in an attempt to determine the
actual need of the project based on usage and future projections .
It appears that each time an airport manager is hired, the first item
on the agenda is to come up with his own version of an airport master
plan and to justify his plan based on the activity at the airport .
To count how many master plans have been presented, you only need to
count back the number of airport managers that have been hired. The
basis of every one of these plans has been the high traffic volume at
the airport and all the safety related issues that would go along with
a facility operating under these conditions. Over and over we have
been told that the Greeley-Weld County Airport is the third busiest
in the state, and the airport manager stated on a recent local tele-
vision show that the number of operations was approaching 200, 000 per
year .
Those of us who use the airport and who have been there long enough to
have been a part of the history of the airport , know this is utter
nonsense and is a total fabrication. Attempts to question their
figures have brought only ridicule and contempt so the only alternative
remaining was to conduct a totally independent survey . To do this a
count was conducted for a period of ten days . The test was conducted
only during perfectly clear flying weather and with surface winds of
less than 10 knots. As with any survey, these figures represent only
a snapshot of a given period of time and the numbers are then projected
to provide reasonably accurate annual results .
The results of this count are enclosed for your consideration . In
view of these results it is hoped that the Council and the County
Commissioners will re-evaluate the decision to support this expensive
ill-conceived project. We look forward to additional dialogue with
these entities before proceeding with furth r action
C azte.

The count was conducted only on days when the airport was operating
under visual flight rules and the persons conducting the count were
advised that should the weather deteriorate , or the wind exceed
approximately 10 knots , the count should be terminated for the day.
The count was conducted on weekends and on various days of the week .
The days the count was conducted and the hours counted are as follows :
Day Date Operations Hours Avg. per hour
Saturday 2/19/94 239 12 19. 9
Wednesday 2/23/94 87 8 10.E
Thursday 2/24/94 56 12 4 .6
Sunday 2/27/94 173 12 14 .4
Monday 2/28/94 54 9 6.0
Tuesday 3/01/94 133 12 ]. 1 .0
Friday 3/04/94 202 12 16 .8
Saturday 3/05/94 361 12 30.0
Sunday 3/13/94 229 12 19.0
Wednesday 3/] 6/94 27 4 6.8
if we break the above numbers down into a daily average, we will use
the numbers based on a 12-hour period of time. This method produces
the following results:
8 full 12 hour days=1507 operations or 188. 4 per day. Pro-
jected for the year this would produce 68, 756 operations or
37. 7 percent of the operations used to justify the master
plan.
If we break the count down even further and use an hourly average , we
then use all the figures shown above and make our projection based on
12 hours per day - 365 days per year . This method produces the fol-
lowing results:
105 hours=1561 operations or an average of 14 .86 per hour.
Projected for 365 days would be 65,086 operations or 35. 7
percent of the operations used to justify the master plan.
It should be noted at this point that we have included two full week-
ends which has inflated the count substantially so the above percentages
are more than likely well on the high side .
No attempt was made to factor in certain numbers to reflect night
operations nor was any attempt made to reduce the numbers in any way
to provide for days of inclement weather when there are few, if any,
operations . We feel we are more than fair in this regard as bad
weather and high wind cancellations would far exceed the number of
night operations. To recap the count on a daily average shows the
following:
Saturday 300 or 25 per hour
Sunday 201 or 16. 75 per hour
Monday 54 or 6 per hour
Tuesday 133 or 11 per hour
Wednesday 87 or 9. 5 per hour
Thursday 56 or 4 .6 per hour
Friday 202 or 16.8 per hour
Method number 1 (Daily count) produces 68, 796 as opposed to 182,000
Method number 2 (Hourly projection) produces 65,086 as opposed to
182,000.
