The site location is shown in figure 1 below and is comprised of two separate tracts. Figure 1: Site Location 13 C14-2025-0090 - West Martin Luther King Jr Blvd and Nueces Street; District 91 of 6Date: Subject: January 22nd, 2026 MLK – Rio Grande – 18th St Redevelopment ZTA The purpose of this ZTA is to provide support for rezoning from CS, CS-MU, GO, and DMU-CO to DMU-CO. The proposed development is anticipated to remove the existing 17,574 SF of laundry services, 2,584 SF of fast-food without drive thru, 1,232 SF of bakery without drive thru, 49 dwelling units of low-rise multifamily, and 2,333 SF of office to include 32,624 SF of retail and 476 hotel rooms on the north tract, and 287 dwelling units of high-rise multifamily and 35,100 SF of retail on the south tract. Adjacent Roadway Characteristics: The development is proposing two (2) driveways along the alley that runs between the two tracts. The location of these driveways is shown as P1 and P2 in Figure 2 below. Figure 2: Proposed Driveway Locations As indicated on the site location map and the conceptual site plan (Figures 1 and 2), the MLK – Rio Grande – 18th St Redevelopment is bounded by W MLK on the north, Nueces St on the east, 18th St on the south, and Rio Grande St on the west in Austin, TX. To adequately describe the significance of the roadways within the vicinity of the site, a further characterization is provided for each. Average daily traffic estimates for these roadways were collected in November of 2025. The Austin Strategic Mobility Plan (ASMP) catalogs the classifications of these major roadways and documents proposed improvements. W Martin Luther King Jr Blvd: W Martin Luther King Jr Blvd along the site frontage is currently a three-lane Level 3 road in the ASMP, requiring 100 ft of ROW. The ASMP calls for improvements including corridor mobility improvements. Based on traffic counts, the 2025 Average Daily Traffic (ADT) on W Martin Luther King Jr Blvd is 21,405 vehicles per day (vpd). The posted speed limit is 30 mph.

The ASMP calls for improvements to the sidewalk and bicycle facilities. Based on traffic counts, the 2025 ADT on Nueces St is 4,014 vpd. The posted speed limit is 25 mph. W 18th St: W 18th St along the site frontage is currently a two-lane Level 1 road in the ASMP, requiring 80 ft of ROW. The ASMP calls for improvements to bicycle facilities. Based on traffic counts, the 2025 ADT on W 18th St is 976 vpd. The posted speed limit is 25 mph. Rio Grande St: Rio Grande St along the site frontage is currently a two-lane Level 1 road in the ASMP, requiring 80 ft of ROW. The ASMP calls for improvements to bicycle facilities. Based on traffic counts, the 2025 ADT on Rio Grande St is 3,643 vpd. The posted speed limit is 25 mph. Trip Generation and Traffic Analysis Based on the Institute of Transportation Engineers (ITE) Trip Generation Manual (11th Edition), the development will generate 9,879 daily, unadjusted trips, 460 AM peak hour trips and 752 PM peak hour trips. Adjusting for a Transportation Demand Management (TDM) reduction of 60% and existing trips, the development will generate 852 daily, adjusted trips, -68 AM peak hour trips and 10 PM peak hour trips.

The applicant has the flexibility to substitute and/or add other relevant TDM measures as per the Transportation Criteria Manual (TCM) at the time of site plan as long as an overall trip reduction of 60% is achieved.

The ZTA identified a mini roundabout at Nueces St & W 18th St as a potential improvement, which will be reevaluated at the time of site plan. Please see Figure 3 below for the improvement extent. 3. The ZTA recommends improving the intersection sight distance along Nueces St with the following improvements, which can be seen in Figure 3 below: • Trim and maintain the tree adjacent to the northwest corner of Nueces St & the alley 4. The City of Austin reserves the right to reevaluate any or all identified improvements associated with this case at the time of Site Plan review. 5. The ASMP ROW requirements and dedication will be reevaluated and completed at the Subdivision or Site Plan phase of development, whichever comes earlier. 6. Street Impact Fee (SIF) Ordinances 20201220-061 and 20201210-062 have been adopted by City Council and are effective as of December 21, 2020. The City has started collecting street impact fees with all building permits issued on or after June 21, 2022. For more information, please visit the City’s Street Impact Fee website. A Street Impact Fee calculation shall be performed at the time of building permit application. 7. This ZTA does not relieve a development of its Transportation Assessment or Full TIA requirement at time of site plan. 8.
