W 49th St is less than 30 feet wide with over 1,200 vpd, whereas Ramsey Ave and W 48th St are less than 30 feet wide and below 1,200 vpd. However, the combined tra*ic from the proposed development and existing vehicles will not exceed 49th St’s operational capacity. This capacity is determined by standard transportation engineering principles and the residential street capacity levels outlined in the nationally recognized Highway Capacity Manual (HCM). O2site Transportation Improvements The area around the site was analyzed to identify potential transportation improvements to be implemented at the time of site plan. The ‘Recommended Improvement’ exhibit attached at the end of this memo identifies several potential improvements based on this review. Improvements identified in this memo are recommended for the applicant to construct at the time of site plan to achieve the TDM reduction target and mitigate tra*ic impacts. Street Impact Fee and the Roadway Capacity Plan At the time of building permit, the site will be subject to the Street Impact Fee (SIF). SIF funds for this site may be used for design and construction of projects identified in the Roadway Capacity Plan (RCP) Service Area ‘I’. RCP ‘Project II-11’ identifies intersection improvements at 49th Street and Burnet Road. Recommendations and Conclusions Based on the results of the NTA, ATPW has the following recommendations and conclusions: 1. During site plan review, the developer will be required to construct sidewalks and associated curb ramps on Ramsey Ave and W 48th St along the site’s frontage. 2. During the site plan review, the developer will be required to re-construct sidewalk on W 49th St along the site’s frontage 3. During site plan review, it is recommended the developer construct the following sidewalk improvements to achieve TDM plan trip reduction target. a. Along the north side of 49th St west side of Burnet Road between Lynwood St and the existing transit stop. b. Along the east side of Rosedale Ave and north side of 47th St between 48th St and the transit stop. 4. During site plan review, it is recommended the developer construct a mid-block, raised pedestrian-crossing across 49th Street. 5. As per the ASMP, the required ROW for Ramsey Ave, W 49th St and W 48th St is either 58 or 64 feet. 6. If the number of units proposed in Table 1 is exceeded, the TDS division may be required to reassess the NTA.

This site will be subject to Street Impact Fee (SIF), which will help fund roadway capacity projects identified in RCP necessitated by new developments. The SIF collection amount will be calculated and collected at the time of building permit application. For more information on Street Impact Fees, please visit the City’s SIF website (https://www.austintexas.gov/department/street-impact-fee). 8. This assessment is based on the proposed uses. Any changes in these assumptions may require an updated NTA. 9. This NTA does not grant nor guarantee approval of proposed driveway types or locations. Driveway types and locations will be reviewed with the site plan application. Should you have any questions or concerns, please contact Austin Jones, Supervising Engineer of ATPW at austin.jones2@austintexas.gov or (512)-978-1671. cc: Renee Johns, Program Manager Mustafa Wali, P.E., Development Review Engineer Cynthia Hadri, Zoning Case Manager Page 5 of 5 03 C14-2025-0094 - 2117 W 49th St. and 4709 Rosedale Ave. Multifamily; District 75 of 8 Residential streets in Rosedale are primarily 27 feet wide with no sidewalks. Pedestrian activity, bicycling, children’s activities and more take place along the streets. Many of the older homes have no garage or single- car garage, so there is existing street parking to navigate. The proposed MF6 zoning will create traffic loading far in excess of streets capacity and in direct opposition to the goals of the Austin Strategic Mobility Plan, especially for those with mobility impairment. 49th St immediately west of the proposed multifamily site has already been studied by the City of Austin’s Speed Management Program because of safety considerations, even at existing traffic counts. The Speed Management Program found that traffic-calming treatments were mandated to deal with existing traffic flows. A series of speed cushions were installed through the full 5-block length of 49th St in this area. 03 C14-2025-0094 - 2117 W 49th St. and 4709 Rosedale Ave. Multifamily; District 76 of 8
 The city’s traffic study references the Highway Capacity Manual (HCM) and suggests that capacities of up to 2,000 vpd could be accommodated on 49th St (27 feet wide). The following is from the HCM and says planned capacity should be less than 1,200 vehicle trips per day. The current estimate with the traffic study revisions and the MF6 zoning is 2,414 vpd. The HCM further says that on-street parking and frequent driveways or street intersections will further reduce suggested capacity. Rosedale streets are subject to both of those considerations. 03 C14-2025-0094 - 2117 W 49th St. and 4709 Rosedale Ave. Multifamily; District 77 of 8
