BRIEFING SUMMARY SHEET DEVELOPMENT ASSESSMENT CASE NUMBER: CD-2019-0006 – 614 S. 1st Street PUD REQUEST: Presentation of a Development Assessment Report for the 614 South 1st Street Planned Unit Development (PUD), located at 614 South 1st Street, within the East Bouldin Creek Watershed. DISTRICT AREA: 9 DEPARTMENT COMMENTS: The applicant has submitted a development assessment for a proposed 8.185-acre multifamily development to be known as the 614 S. 1st Street PUD. It is located on the west side of South 1st Street with East Bouldin Creek as its western and northern most boundaries, see Exhibit A: Zoning Map and Exhibit B: Aerial Map. The property is located within the East Bouldin Creek Watershed, which is classified as an Urban Watershed. The proposed PUD is in an area that includes 100-year floodplain, stream buffers (critical water quality zones and erosion hazard zones) and due to its proximity to East Bouldin Creek, the possibility of critical environmental features (CEFs). CEFs were not identified within the development assessment application but have been requested to be shown if present on the PUD application. The applicant’s proposed PUD consists of up to 550 residential units (apartments) with underground parking and a maximum building height of 120’. The proposed project will be more compact than the existing development on site (Timbercreek Apartments), reducing and removing impervious cover currently located in environmentally sensitive areas. Vehicular access to the PUD will be from South 1st Street through an existing access easement agreement with the neighboring apartment property to the south. On the Imagine Austin Growth Concept Map, this site abuts the South Central Waterfront District and is along an Imagine Austin Activity Corridor (South 1st Street). The applicant is current working with the Austin Transportation Department (ATD) on potential roadway improvements on S. 1st Street (new signal, pedestrian hybrid beacon, etc.) at the project’s driveway per the Austin Strategic Mobility Plan (ASMP) for additional protection to cyclists and pedestrians crossing the street. The applicant has stated in their application materials that the project will meet or exceed all applicable Tier One requirements, and several Tier Two items (water quality, drainage, restoration, art, community amenities, transportation, affordable housing, accessibility and local small business). By meeting or exceeding these items, the applicant has stated the proposed PUD will result in a superior development compared to that which could be developed under conventional zoning standards, see Exhibit C: Letter from Agent …

CASE MANAGER COMMENTS: The proposed Austin Green PUD contains a 2,126 acre active sand and gravel mining site (a basic industry use) and is generally located at the intersection of SH 130 and Harold Green Road, with limited frontage on FM 973, Platt Lane, and FM 969, and bounded by approximately 3.2 miles of Colorado River frontage along its southern boundary. Except for a portion of the Colorado River frontage west of SH 130 that has development reserve (DR) zoning, the site is currently outside of the City limits and proposed for limited purpose annexation and concurrent creation of a Municipal Utility District (MUD). Similarly, except for the Colorado River frontage, all of the surrounding properties are located outside of the City limits. Land west of SH 130 is characterized by industrial and open space uses, with manufactured home and detached single family residential subdivisions bordering the southwest property boundary. The majority of the adjacent land east of SH 130 functions as open space, with the Austin Colony …
Exhibit B - Summary Letter Austin Green PUD Superiority Table ITEM 2.3 TIER 1 REQUIREMENTS General REQUIREMENT PROPOSED PUD SUPERIORITY 2.3.1.A: (MEET) Meet the objectives of the City Code. 2.3.1.B: (MEET) Provide for development standards that achieve equal or greater consistency with the goals in Section 1.1 (General Intent) than development under the regulations in the Land Development Code. • Austin Green will meet the objectives of the City Code. • Austin Green will provide for environmental, community, design and regional goals that meet or exceed Code standards and encourage high-quality mixed-use development. • Austin Green will encourage high-quality development with extensive open space areas. • Austin Green will provide a mixed-use project that adds employment, housing and other activities as described for this Town Center location in the Imagine Austin Comprehensive Plan. • At the densities proposed, Austin Green can help • achieve the vision of a Major Town Center in Imagine Austin, significant housing units as expressed in the Austin Strategic Housing Blueprint and transit- supportive densities in the Austin Strategic Mobility Plan. This is possible because the site has great mobility opportunities, few residential neighbors that would push back on such densities, the potential for transit service as CapMetro’s service area expands and proximity to the airport, which will support an employment center. In addition to the rare characteristics of the site that make it perfect for higher densities than in other previously settled parts of the city, it is a site that the city wants restored and put into public use for recreation and a regional trail connecting downtown Austin to downtown Bastrop as described in the Austin Urban Trails Master Plan, Colorado River Corridor Plan, Travis County Parks Master Plan and the Austin- Bastrop River Corridor Plan . This level of reconstruction and dedication is unachievable with lower densities. • Austin Green PUD will provide 761.75 acres of combined parkland and open space (Exhibit F- Proposed Parkland and Open Space Master Plan). To meet Tier 1, 196.58 acres of open space would be required, we have provided 761. 75 acres. That is nearly four times as much open space as needed to achieve this superiority item. In addition, except in the areas where public parks and OS areas are adjacent to rivers, major highways or utility easements, parks and open space must have direct frontage on a road for 20% of its edge and must …
