Item 7B - Threshold WorksheetTraffic Impact Analysis Title of Plan I Philips Edision Southlake THRESHOLD WORKSHEET Case Number ZA21-0059 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 parking 100 spaces average per driveway. The total site has 383 spaces. There are 6 driveways. That equates to 64 spaces per driveway. Criteria #2:Any driveway in the development is projected to serve 1000 or more vehicles per day.* Please see the attached worksheet. The change in traffic does not create a significant change in the traffic counts per driveway. Criteria #3:Any driveway in the development is projected to serve 100 ingress vehicles or more in the design hour.* See attached sheet. The increase in traffic does not generate a significant increase in traffic * 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.
