Re: Trip Generation Memo for Proposed Development at 479 N. Kimball Avenue in
Southlake, Texas
DeShazo Project # 24070
Dear Mr. Timothy,
DeShazo Group, Inc. (DeShazo) has been tasked to prepare a trip generation memo for the 479 N. Kimball
Avenue development in the City of Southlake. The proposed development site plan can be found in Exhibit
1 at the end of the memo.
To estimate the trip generations for the proposed development, we consulted ITE for a "Fine Dining
Restaurant" however, ITE does not have a category specifically relating to an event space that will mostly
be used for weddings. Because of this, we had to make some assumptions about the trip generations for
the event space. Below are the assumptions our firm used.
1. For the fine dining restaurant, we assumed that the busiest times would be from 5 pm —10 pm from
Sunday to Thursday and 5 —11 pm on Friday and Saturday.
2. For the event space, we assumed that the busiest times will be roughly 5 pm — 2 am once or twice a
week, Saturday likely. This is due to the event center mostly anticipating wedding events. The event
will likely be shorter events, but there will be prep work, setup, and breakdown associated with the
events. We assumed that the additional activities would increase the time people would be at the
event center.
3. For the development, we assumed that most people would share vehicles (2 passengers per vehicle),
but that some people would arrive individually.
4. For the development, we also assumed that there would be some ride -hailing and ridesharing trips.
5. The site is proposing 150 parking spaces for both the restaurant and event center which we took into
consideration in our analysis.
After gathering the ITE data and assumptions for trip generation, we calculated the trip generation for the
proposed development according to Table 1 below.

Totals: 721 31 16 16 142 83 60 774 217 117 101
Expected Trips for the Event Center:

PM Peak Hour = 30% of total seating capacity
SAT PM Peak Hour = 50% of total seating capacity
•m••1��•l��l:�:y:�tr�:�r_��•i_•v
#1 The development exceeds parking 100 spaces on average per driveway.
The proposed development will have an 8,600 SF fine dining restaurant and a 250-seat max capacity event
center. Additionally, the development proposes two access drives and 150 Parking spaces. Based upon the
trip generation summary and considering 50%-50% distribution among the two drives, both drives are
expected to have less than 100 parking spaces each.
#2 Anv driveway in the development is proiected to serve 1000 or more vehicles per day.
Based upon the projected trip generation summary the site is not expected to attract more than 1000 daily
trips.
#3 Anv drivewav in the development is proiected to serve 100 ingress vehicles or more in the design hour.
Based upon the driveway configuration both drives are proposed as right-in/right-out. Due to this
configuration, it is expected that there will be more ingress traffic at the southern drive, as it will be the
first access point for all the site traffic. The development is expected to generate 117 peak -hour ingress
trips on a typical Saturday. Even with a conservative 90% traffic distribution, an estimated 105 cars would
be expected to ingress the southern drive. This would make this development warrant a TIA.
FINDINGS:
DeShazo found that the estimated trip generations for the proposed development were expected to be a
maximum of 721-weekdav trips and 774 Saturdav trips. This would indicate that the development would
not serve 1000 or more vehicle trips a day.
DeShazo also found that the development is proposing 150 parking spaces for both land uses. The provided
site plan shows 2 access driveways that service the site. This would mean that each driveway would have
75 parking spaces per driveway if we consider a 50%-50% distribution.
Finally, DeShazo found that the proposed development is anticipated to have 117 ingress vehicles during a
Saturday peak hour. This would warrant the development to have a TIA performed based on the city's
standards.

Trip Generation Memo for the Proposed Development in Southlake, TX
CONCLUSION:
DeShazo recommends that the development have a formal TIA performed based upon the high number of
parking spaces for the development and the number of ingress vehicles exceeding 100 hourly trips based
upon the findings for a Saturday peak hour.
The completed/filled-out Trip Generation worksheet for this proposed development provided by the city
of Southlake is provided in Exhibit 2 at the end of the memo.
I hereby certify that this project does exceed the third threshold criteria presented above and therefore
the development would warrant a TIA in accordance with Section 3.4 of the Driveway Ordinance No. 634
of the City of Southlake.

Traffic Impact Analysis
Title of Plan I Trip Generation Worksheet for 479 North Kimball Ave in Southlake, TX Case Number
THRESHOLD WORKSHEET
Driveway Ordinance No. 634 requires that a Traffic Impact Analysis (TIA) be submitted with development applications (zoning,
concept plan, site plan, etc.) if the proposed development exceeds one or more of the three threshold criteria listed below. No
development applications will be accepted unless accompanied by a TIA. For those projects that do not exceed any of the
three criteria, a TIA Threshold Worksheet must be submitted and approved by the City Engineer in lieu of the required TIA prior
to submittal of the development application. Please describe in detail your evaluation of each criteria listed below. Additional
sheets may be attached if necessary.
Criteria #1:The development exceeds parkinq 100 spaces average per driveway.
The- proposed development will have an 8,600 SF fine dining restaurant and a 250-seat max capacity event center.
Additionally, the development proposes two access drives and 150 Parking spaces. Based upon the trip generation
summary and considering 50-50% distribution among the two drives, both drives are expected to have less than 100
parking spaces each.
Criteria #2:Anv drivewav in the development is proiected to serve 1000 or more vehicles per day.*
Based upon the projected trip generation summary the site is not expected to attract more than 1000 daily trips.
Criteria #3:Anv driveway in the development is proiected to serve 100 ingress vehicles or more in the design hour.*
Based upon the driveway configuration both drives are proposed as right-in/right-out. Due to this configuration, it is
expected that there will be more ingress traffic at the southern drive, as it will be the first access point for all the site
traffic. The development is expected to generate 117 peak -hour ingress trips on a typical Saturday. Even with a
conservative 90% traffic distribution, an estimated 105 cars would be expected to ingress the southern drive. This
would make this development warrant a TIA.
* Unless approved otherwise, trip generation rates should be based on the most recent edition of the Institute of Transportation
Engineers (ITE) Trip Generation Manual.
I hereby certify that this project does not exceed any of the three threshold criteria shown above and therefore the development
would not warrant a TIA in accordance with Section 3.4 of the Driveway Ordinance No. 634 of the City of Southlake.
