THRESHOLD WORKSHEET
Title of Plan RPAI Central Avenue and Main Street Retail Building Case No.LAi���
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 proposed retail building is located in the block of Southlake Town Center bound by
Grand Avenue, Main Street, Central Avenue and Southlake Boulevard. The block is served by
four driveways which currently provide access to 291 parking spaces, and will provide access
to 270 parking spaces after the retail building is developed (average of 68 spaces per driveway).
Criteria #2:Any driveway in the development is projected to serve 1000 or more vehicles per day.*
The 4,000 square foot retail building is projected to generate 151 weekday daily trips and
184 Saturday trips based on ITE 10th Edition trip generation rates.
Criteria #3:Any driveway in the development is projected to serve 100 ingress vehicles or more in the design hour.*
The 4,000 square foot retail building is projected to generate 4 weekday AM peak hour trips
(2 inbound and 2 outbound), 15 weekday PM peak hour trips (7 inbound and 8 outbound) and
18 Saturday peak hour trips (9 inbound and 9 outbound) based on ITE 10th Edition trip
generation rates.
° 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.
