Dan,
Please review the letter I sent yesterday, which is addressed to Damien and should be reaching your office today or
tomorrow. It contains the methodology that Damien and I had agreed on a couple of weeks ago. If you still have
questions, please call me on Monday to set up a time to get together, as I am out of the office tomorrow and Friday.
Thank you.
Sincerely,

Jon,
Cindy and I would like to meet to discuss the trip generation methodology with you regarding the traffic impact study
scope of work issued for the Jackson's Food Store Remodeling Project on Gateway. We have been working on this
project and it is unclear exactly how you would like a trip generation to be addressed based on your calculations.
We look forward to meeting with you to clear this matter up.
Thanks!
Dan

Jon,
I apologize for your numerous extensive concerns below. I have a very large project load right now and apparently have
not done a very good job coordinating what is turning into a complicated traffic study scoping process with you. My
intention was not to ignore or deviate from the scope. The study was actually pretty much done before you were able to
provide the draft scope. The intent was to simplify the approach on what I would consider a relatively straight forward
project proposal. I will not submit it that way if you don't agree with the approach. I will have one of my traffic analysts
contact you this morning to arrange a meeting with you and try to understand the trip generation methodology. Thanks for
your continued extensive attention to this project.
Thank you,
Damien Gilbert, P.E.

Damien,
Your email surprises me a little. First, I have been waiting for a week and a half for your response from my previous
email, which I had sent as a courtesy to see if you wanted me to add to or modify the draft TIA scope. That is why I have
not sent the final scope. It seems odd that you are now proceeding with your study before receiving the final TIA scope.
Second, we had already in our April 15th meeting jointly settled on how to deal with the additional trip generation,
which was to use the average between ITE Codes 945 and 853 using the square footage of the proposed convenience
store. Also, in that meeting, you had stated that the stand-alone convenience store AM/PM trip (Code 851) was not an
accurate representation, which now you plan to use in your study. I, however, agree with your original stance that ITE
Code 851 is not representative of your proposed development, as the ITE manual describes Code 851 as a market with
no gas pumps.
It seems peculiar that you changed the approach from what we agreed because it is "uncompressible" [sic]. I had
written up the computations of the averages in the proposed scope I em ailed you. I have no issues if you utilize my
work after checking it. After looking at the ITE manual further, I am even more convinced that our original decision was
a fair one. The existing convenience market is 989 square feet. (The developments studied in the ITE Code 945 had
buildings that averaged a little over 1,000 square feet.) The proposed convenience market is 3,384 square feet. (The
developments studied in the ITE Code 853 had buildings that averaged somewhat under 3,000 square feet.) These facts
give credence that our original agreement.
So that you can continue your study properly, I have enclosed a digital copy of the final scope, which I will also send via
mail on paper. If you would like to discuss it, please contact me. Otherwise, if you do not follow the scope, the TIA may
be deemed incomplete at the PRE-Submittal meeting.
Sincerely yours,

Jon,
Sure, please do. I am almost done with the study.
By the way, to keep things simpler, I am just applying the stand-alone convenience store AM/PM trip generation for the
minor study distribution, and will address SDC rate separately. The averages and combinations of uses were too hard to
articulate in the study to the point where it was almost uncompressible. The rate is pretty close to what you were trying to
get a!.
I hope you have a nice weekend.
Thank you,

Damien,
Attached is the TIA scope for the Chevron Station at the corner of Gateway Street and Kruse.
Thank you for meeting last week. I believe it was productive. Just to summarize our meeting, here are a few bullet
points:
. We agreed that the trip generation need not to be addressed for LOS concerns. The City Council
has not wanted to stifle development in the Gateway area because of transportation issues that
are being worked on presently. Trip generation will only need to be considered as it affects the
safety of the site and it's adjacent intersection.
. I explained that I agreed with the first points on page two of your memo (stamped and dated
April 2, 2010), but that the last paragraph was not accurate.
o The memo stated, "Based on the City's Trip Generation Rate, Land use code 853
(Convenience Market with Gas Pumps) was selected as the most appropriate land use for
this site. The rate for this use was base on the Trip Generation Manual, as the City's rates
are based on an expired Edition of that manual."
o I explained that I had used the latest ITE Manual (the 8th Edition), and that I did not use
ITE Code 853. I had used ITE Code 945 (Gasoline/Service Station with Convenience
Market), which puts the emphasis on the gas station rather than the store.
· We agreed that the main issue is safety, and an equitable solution to coming up with a Trip
Generation would be to split the difference between ITE Codes 945 (Gasoline/Service Station

with Convenience Market) and the 853 using the square footage of the convenient store. As the
ITE Code does not included a number for the weekday trips for Code 945 using square footage,
we considered it would be appropriate to approximate that from the AM and PM values of the
ITE Code 945's Fuel Position data and square footage data.
Since then, I have received your AutoCAD floor plan of the proposed building. Thank you. I will base my TIA on what I
see there.
You mentioned you wanted copies of the study work prepared for Best Buy, Michael's Crafts, Starbucks, the two new
giant Hotels, and the couplet corridor analysis.
For the couplet corridor, I cannot give you anything more detailed beyond the paper copies I gave you on April 22,
as those drawings are the most detailed documents we have to this date.
For the Holiday Inn and the Hilton Garden Inn, I have looked and found no studies in the files.
For Best Buy, Michael's Crafts, Starbucks, or any other developments, I will direct you to Karen LaFleur in the
Development Services Department (744-3387).
You mentioned CH2M Hill's plans and the median down Gateway and asked why this intersection's safety issues were
not dealt with in it. I would suggest you speak with Jeff Paschal for the answer to that question. I can say that those
plans are for Phase I, and that Phase II will provide a couplet which will make right-in, right-outs for the Chevron station.
The plans in hand for Phase I did not, however, take into account the additional trips which would be added by this
development.
The development that your client has proposed would triple the site's convenient store, while keeping the number of
gas pumps constant. Therefore, it is appropriate to look at the ITE Manual in terms of square footage of the building.
The only values in the ITE Trip Generation manual which could be considered for this site are as follows:
Land Use
Weekday
Trips I
KSF
Convenience Market (ITE Code 8S1) 737.99
Convenience. Market wi Gas Pumps (ITE Code 853) 845.60
Service Station wi Convenience Market (ITE Code 945) Not listed
The first land use listed here (851) is described in the ITE manual as being one of the markets that "are open 24 hours
per day" and "sell convenience foods, newspapers, magazines and often beer and wine..." wh'ich matches this
development. The manual continues, though, declaring, "... they do not have gasoline pumps." While this statement
removes this from.being the first (and maybe even second) choice, it is worthy of examining for comparison sake for the
manual lists Codes 853 and 945 as related uses.
The middle land use (853) has the same descriptors as listed for 851, except that it sells gas as well-though the primary
purpose is "selling of convenience items, not the fueling of motor vehicles." This code could be appropriate, as the size
of the store is being tripled. However, unless a small restaurant (e.g. A&W's) were being added, my judgment tells me
this code may not be the best, especially as the Chevron station is at an intersection relatively close to the 1-5
interchange. (See following.)
The last land use listed (945) is described similarly as to code 853, but that the primary business is selling gas. This
description definitely matches the establishment's present description. Whether or not tripling the size of it would shift
it into the Code 853 category is open for debate.
This is the logic I went through to rationalize averaging between two different land uses, an unusual choice to make-
especially when one must do some creative (though logical) mathematics to come up with an number for the average
trips on a wee~day per one thousand square feet offloor space.

I have enclosed an excel sheet with my calculations on the ITE Trip Generation Rates we were thinking of the same
creative mathematics. (Relationally, the creative part of the math showed a correlation difference of only 7%, as you
can see in the attached.) Upon examination you can see that in using the method we had agreed upon, the value for
weekday trips/lOOO square feet of gross leasable area was 1036.
Enclosed is also my draft of the TIA scope. Let me know if there is anything you think that should be added/modified on
it.
Thanks for working with me on this complicated but potentially rewarding endeavor. I know that you, too, care about
reducing crashes and injuries in our city-and we both know this location could use some assistance.
Sincerely,
