Re: Hotel Development Proposal, Gateway Area, College Station, Texas
Dear Mr. Kling:
At your request I am providing this letter addressing the issue of trip generation for the
proposed hotel tract near the Gateway Development adjacent to University Drive in College Station.
It is my understanding that you are submitting a site plan for the hotel tract proposal and require
consideration of traffic impacts. It is further my understanding that the driveway connections to
University Drive will not be altered in number or configuration.
As you know I provided a Traffic Impact Assessment for the original Gateway Center in
2002. I have spoken with Joe Guerra at the City of College Station and he is aware of the original
study. In that document I included an area called the West Retail Tract which included about 20
acres on the west side of the major driveway that connects to University Drive across from Forest
Drive. In the TIA this tract included some 340 units of medium density residential development and
20,000 square feet of specialty commercial development for purposes of predicting trip generation
and traffic impacts. These trips were allocated to the driveway configurations as they currently exist,
as shown in the study.
It is my understanding that the current proposal includes a suite type hotel, generally for
extended stay guests, which will have 105 rooms. I have considered ITE trip generation rates for
such a facility (Land Use 311 in the Trip Generation guide.) Such facilities generate about 30% less
traffic than a typical hotel and generate considerably less traffic than the assessed commercial use.
As such the proposed land use would generate significantly less traffic than what was assessed in the
2002 study and this development proposal should be covered by that document. If you have
additional questions please let me know. I can submit additional data upon request.
Sincerely,
Jeffrey T. Milburn, P.E.

Re: Restaurant Development Proposal, Gateway Area, College Station, Texas
Dear Mr. Patterson:
At your request I am providing this letter addressing the issue of trip generation for the
proposed restaurant addition to the Gateway Center. I have reviewed the site plan for this 4568
square foot Newks Express Caf6 and the other development information you provided, including the
revised site plan for the majority of the original Gateway tract. This revised site plan includes actual
square footage and land use type for the Gateway development. As you know I provided a Traffic
Impact Assessment for the original Gateway Center in 2002. That traffic impact assessment was
based on the site development plan proposed at that time which was represented on Figure 2 on page
4 of the original report.
To accurately assess the impact of this development proposal I have taken the information
provided to make adjustments to the trip generation calculations presented in Table 2 (page 12) in
the original study. I have attached these calculations to this letter for reference. Changes made are
highlighted in red on the revised Table 2 and include the following:
1. Correction of the square footage of the Home Depot from 94,977 sf to 94,964 sf
2. Revision of Restaurant 1 to include Freebirds at the original trip generation rate (Land Use
932) using estimated square footage from satellite photos (2300 sf)
3. Addition of Chicken Express as a drive through at higher trip generation rate (Land Use 934)
using estimated square footage from satellite photos (2200 sf)
4. Addition of Car Washes in the east tract based on building area from satellite photos (7000
sf) using the trip generation rate (Land Use 948)
5. Adjustment of Major Anchor 1 building area as per the site plan you provided, from 88,400
sf to 71,372 sf
6. Adjustment of Anchor 2 & 3 tract as per the site plan provided from 48,000 sf to 31,193 sf
for Anchor retail
7. Adjustment of Anchor 2 & 3 tract as per the site plan provided from 16,800 sf to 27,672 for
Specialty retail
8. Removal of Restaurant 4
9. Adjustment of Anchor 4 tract as per the site plan provided from 20,000 sf to 0 sf of Anchor
retail

Page 2
10. Adjustment of Anchor 4 tract as per the site plan provided from 14,000 sf to 23381 sf of
Specialty retail
11. Addition of the proposed restaurant at 4568 sf
These calculations indicate that the trip generation of the existing development combined with the
new proposed development is 69 vehicles per hour less than the original proposal which was
assessed in the 2002 TIA. This means that the current development proposal would not be expected
to negatively impact traffic as compared to the original TIA. It is interesting to note that this
development proposal represents full build out of the site and that the development, as completed,
will be expected to generate less than the original TIA assessed eight years ago. The difference is
from 1519 vph in the peak hour to 1450 vph, only about 4.5%.
If you have questions regarding this information please call on me at any time.
Sincerely,
Jeffrey T. Milburn, P.E.
