Proposing 750 multifamily units in 2 phases. • ½ mile from Southpark Meadows Town Center, along Imagine Austin Corridor/ASMP TPN. 6.25 acre public parkland, and 25’ wide (2.5 acre) recreational trail connecting to Meadows. Subdivision/S. 1st Street – roughly one-fourth of the project. Zoning Application submitted September 2019. • Change zoning from I-RR (Interim-Rural Residential) to MF-4. Revised Zoning request. • “MF-4 Light” (MF-4-CO). o Limit to MF-3 development standards (except height of 60’ along South 1st St., located 300’ away from Meadows/Knolls subdivision).  Allows clustering development.  Achieves more open space/smaller footprint, more tree preservation. o Enhanced compatibility buffering from Meadows and Knolls residential subdivision, more than current code and LDC Revision requirement. Zoning staff recommends approval of MF-4-CO About 12 meetings with Knolls HOA and Meadows HOA representatives Meadows HOA supports MF-4-CO (see page 30-32 of backup) Proposed Development Standards (see page 34 of zoning backup) a. MF-4-CO zoning (for maximum 60’ height) – MF-4 “Light”. b. MF-3 development standards for all other zoning development standards, except for 60’ maximum 1. Zoning Development Standards height along S. 1st Street. 750 dwelling units maximum. c. 2. Buffering a. Proposed compatibility buffering: i. South property line: Minimum 70’ wide dwelling unit setback. ii. West property line: Minimum 50’ wide dwelling unit setback. o 30’ wide abandoned pipeline easement area along western Riddell tract at the back of adjacent residential lots/fences creates an additional 30’ buffer – total 80’ wide dwelling unit setback. b. Summary of current and proposed LDC compatibility requirements. i. Current Code Compatibility: 25’ building setback for maximum 30’ height or 2 stories; 50’ building setback for maximum 40’ height or 3 stories. Proposed LDC Revision Compatibility: 20’ building setback, and building height can achieve maximum height per zoning at 100’ from property line. ii. c. 6’ high fence along west and south property line (wrought iron along south, per Meadows HOA request) Proposed Development Standards (see page 34 of zoning backup) 3. Area Infrastructure a. b. c. d. Construct signalized intersection of Wayne Riddell Loop/S. 1st Street/Akins High School Access. Extend/dedicate Wayne Riddell Loop. a. TIA: 3 lanes at S. 1st Street, narrowing to 2 lanes at existing Wayne Riddell Loop. Install traffic calming devices along existing Wayne Riddell Loop, voluntary by developer (per Knolls HOA request). Provide Safe Route to School (Akins High). • • • Extend sidewalks from S. 1st Street to connect to existing Wayne Riddell Loop (per Knolls HOA request). Extend sidewalks along west side of S. 1st Street (including voluntary offsite sidewalks by developer to connect to existing sidewalk at Meadows at Double Creek, per Meadows HOA request). Per ATD - convert buffered bicycle lanes to protected bicycle lanes for Akins High School with delineated posts on S. 1st Street frontage. e. Implement Transportation Demand Management. 4. 6.25 acre Parkland, and Recreational Trail a. Design, build and install at developers expense a system of fences and gates that locks and secures access to Knolls b. c. private greenbelt from the Riddell tract (per Knolls HOA request). Security lighting along jogging path to be coordinated with PARD staff to ensure lighting does not impact adjacent neighbors along south and west property line (per HOA request). Incorporate lighting such as nightwatchmen lights at ROW entrances, and bollard/low lighting along the entirety of the recreational trail (per HOA request). 5. On Site Security Measures. Perimeter security fencing. Secure access gates with fob access for all residents with 1-point logged delivery drop-off/pick-up. a. b. c. HD camera with license plate readers. d. e. 1-2 staff members living on site. Security cameras and lighting on property. Conceptual Plan - Multifamily, Parkland and Recreational Trail Signal + Wayne Riddell Loop Extension (TIA: 3 lanes, narrowing to 2 lanes) (Enhanced Buffer, and changed building configuration per Meadows HOA request) Conceptual Map – South Boundary Development Standards Comparison MF-4 MF-4 “Light” (MF-4-CO w/ MF-3) 40’ along west & south 60’ along S. 1st St. (300’ from residential) Max.

Remaining Issue: Wayne Riddell Loop. Loop. • Whether to approve crash gate, or complete Wayne Riddell Loop Extension from S. 1st Street to existing o Proposed multifamily development works with or without crash gate at existing Wayne Riddell o ATD recommends complete extension Wayne Riddell Loop per TIA  crash gate is policy choice for ZAP and City Council. • Carve out land from Riddell Tract rezoning case to “block” extension of Wayne Riddell Loop. o Multiple City departments would likely not recommend zoning application. o o o Subdivision Code 25-4-151 requires connecting streets at time of subdivision (see page 3, zoning staff report), but ZAP/City Council can approve crash gate. “Shot Clock”/HB3167 requires completing zoning case prior to processing subdivision. Site is constrained due compatibility, Heritage trees, parkland dedication, on-site ponds, and other site constraints. o o o o o o o o o Reasons to Support 750 apartments provides diversity of housing stock per Imagine Austin (adjacent to Imagine Austin Centers). S. 1st Street is Imagine Austin Activity Corridor, and ASMP Transit Priority Network (along with WRL Extension). Proposed bicycle and sidewalk improvements fulfill Bicycle Master Plan, Sidewalk Master Plan, and provide Safe Route to School serving adjacent residents. “MF-4 Light” zoning. Provides for enhanced dwelling unit buffering beyond current LDC (and LDC Revision) requirement – established 70’ from south property line, per request of Meadows HOA. Clustered development, more open space/smaller footprint, preserves Heritage Trees. Fencing along the property line adjacent to single-family homes. 6.25-acre public parkland, and 25’ wide (2.5-acre) multi-use recreational trail connects to Meadows subdivision residents/S. 1st Street. Roughly one-fourth of the project. More than $1.1M area infrastructure improvements to the area. TDM. In addition to TxDOT improvement projects along FM1626 Corridor. Environmental: Adding water quality controls per current regulations. Preserving all Heritage Trees, and ~ 88% of existing trees. Clustered development; parkland. On-site security measures. MF-4-CO zoning is recommended by staff, supported by Meadows HOA. Provides certainty of development of large undeveloped Riddell tract. Riddell Tract Multifamily and Public Park/Recreational Trail
