Code Approach
“Deep Clean and Reset” Approach selected by City Council, with additions:
• Extensive rewriting of content as necessary
• Focus on green infrastructure and sustainable water resources
• Enable broader application of form‐based codes
![Page 13: Green Infrastructure Group Kickoff Meeting · 2020. 2. 20. · Green Infrastructure Working Group Schedule Kickoff Jan. 30 Land Cover & Natural Function Feb. 20 Landscaping & Green](https://reader036.vdocuments.us/reader036/viewer/2022071106/5fe01008cbe079773429a11a/html5/thumbnails/13.jpg)
Next Steps• Working Groups on:
1. Affordability2. Infill, compatibility, and missing middle housing3. Obstacles to small business4. Subdivision regulations5. Green infrastructure
• CodeTALK on green infrastructure Spring 2015• Draft Code for public review Spring 2016• Opportunities for public, board & commission, and Council input at each step

Land Cover and Natural Function
Goals• Ensure adequate natural function for all sites Protect greenfield sites Restore redevelopment and infill sites
• Promote desirable, purposeful open spaces & connectivity
• Want the design and care of our built environment to take advantage of strengths of both pervious and impervious cover
![Page 16: Green Infrastructure Group Kickoff Meeting · 2020. 2. 20. · Green Infrastructure Working Group Schedule Kickoff Jan. 30 Land Cover & Natural Function Feb. 20 Landscaping & Green](https://reader036.vdocuments.us/reader036/viewer/2022071106/5fe01008cbe079773429a11a/html5/thumbnails/16.jpg)
Land Cover and Natural FunctionChallenges• Low natural function on medium to high impervious sites
• Pervious areas don’t necessarily function as intended(e.g., soil compaction)
• Impervious cover limits can produce fragmented landscapes of unconnected, private green spaces
• Application to centers & corridors
![Page 17: Green Infrastructure Group Kickoff Meeting · 2020. 2. 20. · Green Infrastructure Working Group Schedule Kickoff Jan. 30 Land Cover & Natural Function Feb. 20 Landscaping & Green](https://reader036.vdocuments.us/reader036/viewer/2022071106/5fe01008cbe079773429a11a/html5/thumbnails/17.jpg)
Landscaping and Green Transitions
Goals• Functional landscapes with multiple benefits (e.g., urban heat island, water conservation, habitat, enhanced public realm)
• Urban forest preservation and replenishment
• Climate resilience and adaptation to drought
• Green transitions between different land uses
• Practical to implement and maintain the ordinance
![Page 18: Green Infrastructure Group Kickoff Meeting · 2020. 2. 20. · Green Infrastructure Working Group Schedule Kickoff Jan. 30 Land Cover & Natural Function Feb. 20 Landscaping & Green](https://reader036.vdocuments.us/reader036/viewer/2022071106/5fe01008cbe079773429a11a/html5/thumbnails/18.jpg)
Landscaping and Green Transitions
Challenges
• Landscaping code does not apply to dense urban areas (e.g. CBD) or parking lots for remodels
• “Street yard” concept does not work in all contexts
• Inadequate provisions for shade trees & existing trees
• Missed opportunities for onsite infiltration of stormwater and use of non‐potable water
• Transitions between land uses (e.g., centers & corridors and adjacent residential) need refining
![Page 19: Green Infrastructure Group Kickoff Meeting · 2020. 2. 20. · Green Infrastructure Working Group Schedule Kickoff Jan. 30 Land Cover & Natural Function Feb. 20 Landscaping & Green](https://reader036.vdocuments.us/reader036/viewer/2022071106/5fe01008cbe079773429a11a/html5/thumbnails/19.jpg)

Beneficial Use of Stormwater
Recap
• Stakeholder meetings (Watershed Protection Ordinance Phase 2) from Jan. to July 2014
• Final Report of the Austin Water Resource Planning Task Force recommended “Tapping into the Cityscape as a Water Supply Source”
• Phase 2 recognized need for requiring infiltration and/or re‐use of stormwater on‐site for new & re‐development (Maryland Model)
![Page 20: Green Infrastructure Group Kickoff Meeting · 2020. 2. 20. · Green Infrastructure Working Group Schedule Kickoff Jan. 30 Land Cover & Natural Function Feb. 20 Landscaping & Green](https://reader036.vdocuments.us/reader036/viewer/2022071106/5fe01008cbe079773429a11a/html5/thumbnails/20.jpg)
Beneficial Use of Stormwater
Going Forward
Discuss specific proposals for achieving beneficial use of stormwater as part of CodeNEXT:
• Infiltration / Baseflow / Water Quality
• Water Conservation / Drought & Climate Resilience
![Page 21: Green Infrastructure Group Kickoff Meeting · 2020. 2. 20. · Green Infrastructure Working Group Schedule Kickoff Jan. 30 Land Cover & Natural Function Feb. 20 Landscaping & Green](https://reader036.vdocuments.us/reader036/viewer/2022071106/5fe01008cbe079773429a11a/html5/thumbnails/21.jpg)
Stormwater Options for Redevelopment/Infill
Del Curto Rd and Bluebonnet Ln
Goals
• Provide additional flexibility and options to enhance water quality for redevelopment and infill
• Address longstanding problems due to development without sufficient flood controls and/or drainage conveyance
![Page 22: Green Infrastructure Group Kickoff Meeting · 2020. 2. 20. · Green Infrastructure Working Group Schedule Kickoff Jan. 30 Land Cover & Natural Function Feb. 20 Landscaping & Green](https://reader036.vdocuments.us/reader036/viewer/2022071106/5fe01008cbe079773429a11a/html5/thumbnails/22.jpg)
Stormwater Options for Redevelopment/Infill
Burnet Road Corridor
Challenges• Payment‐in‐lieu for water quality only allowed within Urban Watersheds
• Code does not require flood mitigation if impervious cover is not increased and downstream conveyance is not further impaired
• Long‐term ownership and maintenance of green infrastructure
![Page 23: Green Infrastructure Group Kickoff Meeting · 2020. 2. 20. · Green Infrastructure Working Group Schedule Kickoff Jan. 30 Land Cover & Natural Function Feb. 20 Landscaping & Green](https://reader036.vdocuments.us/reader036/viewer/2022071106/5fe01008cbe079773429a11a/html5/thumbnails/23.jpg)
