Fairmont Parkway <br />La Porte, Texas 77571 <br />RE:Review of GCP 16th Street Distribution Center Traffic Impact Analysis <br />City of La Porte, Texas <br />Response to Traffic Impact Review Comments by RPS Klotz Associates <br />Dear Mr. Ensey, <br />Thank you for forwarding review comments from RPS Klotz Associates dated April 25, 2016. <br />After review, we did recognize a coding error in lane assignments at the SH 146 at Wharton <br />Weems diamond interchange. That coding error was corrected and Exhibit A5 replaced, and all <br />simulations re-runwith existing lane geometry asconfirmed via aerial and site/field <br />photography. <br />The simulation results changed very little as trafficvolumes (existing and projected)are <br />relatively low as compared to thesignalized capacity of theinterchange. The level of service <br />remained the same and delay typically changed by less than a second. No changes to the <br />conclusions or recommendations of the study are necessary due to these recalculations. <br />Previous simulation analysis results: <br />12.
