MEMORANDUM Date: To: CC: Reference: August 9, 2024 Aditya Jatar, P.E., BOE Consulting Services Danielle Morin AICP., Julie Apagya Bonney Transportation and Public Works Department Oak Creek Village Zoning Transportation Analysis (ZTA) Final Memo (C14-2023-0047) The Transportation & Public Works Department (TPW) has reviewed the June 27, 2024 “Oak Creek Village” Zoning Transportation Analysis, prepared by BOE Consulting Services. The proposed site includes a Mid-Rise Multi-Family Housing development with 495 dwelling units, located at 2302 Durwood Street in Austin, 78704, Texas (see Figure 1 below). The project will be constructed in two phases and is anticipated to be completed by 2026. To facilitate access to the surrounding roadway network, the development proposes two driveways: Driveway A (existing) on Durwood Street and Driveway B (new) on South 1st Street. These access points are depicted in Figure 1 below. Figure 1: Site Location Adjacent Roadway Characteristics: The site will connect to West Oltorf Street and South 1st Street. Below is a summary of the current conditions around the site: Durwood Street: Classified as a Level 1 road in the Austin Strategic Mobility Plan (ASMP), requiring 64 feet of right-of-way (ROW). Currently, Durwood Street has 46 feet of ROW, with unmarked travel lanes, curbs, gutters, and sidewalks on both sides. In 2024, the average daily traffic (ADT) on Durwood Street was about 1,200 vehicles per day. Trip Generation and Traffic Analysis: Using the Institute of Transportation Engineers (ITE) Trip Generation Manual (11th Edition), the development is expected to generate 1,717 net new daily trips (unadjusted), with 158 trips during the AM peak hour and 140 trips during the PM peak hour (See Table 1 for details). Table 1: Trip Generation The 2024 ADT was estimated using traffic count data, with a 2% annual growth factor applied to project the 2026 volumes. Table 2 shows both current and projected volumes on nearby road segments. Table 2 Projected Volume Analysis The analysis indicates that the unadjusted site traffic, combined with the forecasted volume at full build-out, will exceed the typical ADT range for Durwood Street but remain within the necessary limits. A Transportation Demand Management (TDM) plan was not required as the trip count did not exceed the 2,000-trip threshold. Additionally, evaluations of ROW for adjacent roads, turn lanes for all driveways, and sight distance for the proposed new driveways were conducted. Recommendations/Conclusions: As a condition for approval for the above referenced zoning review case, the applicant shall adhere to the following recommendations: • The development falls under the City of Austin Street Impact Fee (SIF) Ordinance (20201220-061 & 20201210-062). The SIF will be calculated during the Site Plan submission and collected when the building permit is issued. Reductions in the SIF will only be granted after completing specified construction tasks, unless already included into the initial Site Plan application. • The ASMP ROW requirements have been assessed, and the site may require ROW dedications to meet ASMP standards. This will be confirmed during the Site Plan phase. • The site proposes one new driveway on South 1st Street for general traffic circulation. Approval of this ZTA does not guarantee approval of the proposed driveway locations, which will be reviewed further during the Site Plan process by the relevant City departments. • This ZTA does not relieve a development of its Transportation Assessment or Full TIA requirement at time of site plan.
