We are re -submitting this letter, unchanged, until we meet with you to discuss the mitigation options and TIA requirements that you identified. Once an agreement is made, we will revise and re -submit the letter as necessary. If you have any questions about this, please let me know. Sincerely, WALTER P.

This assessment builds upon the previously submitted traffic impact analysis for Tower Point developed by Walter P Moore and submitted to the City of College Station in December 2009. Background traffic volumes, lane configurations along roadways and at intersections and driveways, and anticipated land uses of other parcels are assumed to be unchanged from the previous TIA. Trip distributions are also assumed to be unchanged. Since the analysis in the TIA was for the AM and PM peak hours of the roadways, the rates for the adjacent street were used. The rates shown in this letter are consistent with the rates used in the previous TIA which was approved in February 2010 for the complete development. It should be noted that Trip Generation does not provide rates for the AM peak hour of the adjacent street since most retail establishments do not have a high AM peak hour volume. For this reason, an average trip generation rate of 0.3 for the AM peak hour and the ITE rates for the PM peak hour of the adjacent street were used. This report will compare the trip generation values for the previously assumed land use for this parcel with the proposed land use. This letter report addresses four lots. In the previous TIA, three parcels in question were identified as lots 7, 8, and 18. The parcel identified as Lot 30 was not identified in the previous TIA. This parcel is located off of Arrington Road, north of the detention pond. Three of the proposed lots surround the HEB development south of the roundabout at Arrington Road, and one is located to the north of the roundabout. The locations of the lots relative to the Tower Point development are shown in Figure 1. 1301 MCKINNEY, SUITE 1100 HOUSTON. TEXAS 77010 PHONE: 713.630.7300 FAX: 713.630.7396 www.WALTERPMOORE.co.

Lot 18 was previously assumed to be a "Tire Store" (ITE Land Use Code 848) and is proposed to be a "Fast Food Restaurant with Drive -through" (ITE Land Use Code 934). Lot 30 is Intended to be a "High -Turnover Sit -Down Restaurant" (ITE Land Use Code 932). The sizes of the planned lots are as follows; Lot 7 is 4,500 square feet, Lot 8 is 3,640 square feet, Lot 18 is 2,950 square feet, and Lot 30 is 7,506 square feet. Table 1 shows a comparison of the previously defined land uses and square footage and the proposed developments.

The number of trips generated by the development during an average weekday and for weekday peak hours is based on factors such as the land use type and size of the building. Standard rates from the Institute of Transportation Engineers (ITE) publication, Trip Generation Manual, 60 Edition, were used to determine the amount of traffic generated by the various land uses in the proposed development. Trip sharing among all the parcels associated with the large retail parcel of Tower Point was assumed to be 10%. A comparison of the anticipated trip generation between the previous report and the proposed conditions is presented in Table 2.

To accurately assess the impact to the roadways it is important to look at the changes in the development cumulatively. Table 3 provides a cumulative summary of previous TIA letters highlighting the land use changes.

This is less than what is typically needed to require a new traffic impact study. Summary The proposed land uses are anticipated to generate more trips than the land use assumed in the previous TIA. One major source of these new trips is the fire store being replaced with a fast food restaurant. However, the tire store land use is anticipated to relocate to Lot 20, which would replace a planned fast food restaurant with drive through. The new development at Lot 30 is the other development contributing to the additional generated trips. This development is expected to generate less than 50 entering or exiting trips in the peak hour. As the developer continues to make agreements for individual parcels, land uses are being adjusted to create a better overall development. Since some land uses are still being adjusted it is possible that the total change in trips could decrease or equal what is shown in the original TIA. It is our understanding that the developer will continue to provide TIA update letters to reflect future changes as they occur.
