Item 7A - TIA Threshold Worksheet and Trip GenerationTraffic Im act Analysis
THRESHO D W KSHEET
Title of Plan IM gnolia Southlake
Case No.
Driveway O dinance No. 634 requires that a Traffic Im act Analysis (TIA) be subm tted with developm nt applications (zoning,
concept plan, site plan, etc.) if the proposed developm nt exceeds one or m re of the three threshold criteria listed below. No
developm nt applications w Il be accepted unless accom anied by a TIA. For those projects that do not exceed any of the
three criteria, a TIA Threshold W rksheet m st be subm tted and approved by the City Engineer in lieu of the required TIA prior
to subm ttal of the developm nt application. Please describe in detail your evaluation of each criteria listed below. Additional
sheets m y be attached if necessary.
Criteria #1:The developm nt exceeds parking 100 spaces average per drivew y.
No, the developm nt will have 2 driveways, with 106 total parking spaces.
Criteria #2:Any drivew v in the developm nt is prolected to serve 1000 or m re vehicles per day.*
e total estim ted daily trips for the entire developm nt is 236 trips. This is well below the thresheold.
Criteria #3:Any drivew v in the developm nt is prolected to serve 100 ingress vehicles or m re in the design hour.*
e peak hourly trips is 33 vehicle trips. This again is well below the threshold.
* Unless approved otherwise, trip generation rates should be based on the m st recent edition of the Institute of Transportation
Engineers (ITE) Trip G neration M nual.
I hereby certify that this project does not exceed any of the three threshold criteria shown above and therefore the developm nt
would not warrant a TIA in accordance with Section 3.4 of the Driveway O dinance No. 634 of the City of Southlake.
