SUBJECT: PP-CGPA-25-0003 – Trip Generation Analysis Proposed Zone Change from Commercial Office to Residential for Stockdale Ranch
Traffic Engineering has reviewed the Traffic Letter dated August 20, 2025, prepared by Ruettgers & Schuler Civil Engineers.
The purpose of the study was to evaluate the potential traffic impacts of the proposed zone change.
The parcel is located on the southwest corner of Stockdale Highway and Wegis Avenue, consisting of approximately 43 acres. The current zoning is C-O (Office Commercial) with an allowable 665,200 SF of commercial office as per the 2009 traffic study by McIntosh and Associates. The proposed zoning is R-2 to allow for small single-family units (up to 425 units based on allowable density) or multi-family units (up to 567 units based on allowable density).
The trip generation of the two residential options were compared to the approved commercial office trip generation.
As per the trip generation study, the project is expected to generate 576 fewer trips during the AM peak hour and 413 fewer trips during the PM peak hour based on 425 single-family units and the project is expected to generate 655 fewer trips during the AM peak hour and 536 fewer trips during the PM peak hour based on the 567 multi-family units. Since there will be fewer trips than approved, no further analysis is required.
Based on the above, the following mitigations would be appropriate:
Prior to the issuance of building permits:
The project applicant shall participate in the Regional Traffic Impact Fee (RTIF) program by paying the adopted fees in place for the land use type at time of development.
