Motion Sheet CM Kelly June 9th, 2022 Item 61 I motion to add the following to line 120: BE IT FURTHER RESOLVED: The City Manager is directed to come back with recommendations and considerations in the form of a memorandum of required city staff hours to initiate the completion of this resolution by September 1st, 2022.
6/9 Item 61 Water Quality CM Vela Amendment 1 - V4 Proportionate Standards for Missing Middle Housing Add the following WHEREAS: WHEREAS, small scale missing middle housing projects (projects with approximately 3 to 12 units) are required to comply with the same procedures and requirements for review of water quality protections and site plans as large scale multifamily residential projects, while single family homes are not subject to those requirements, creating an incentive for developers to build single family homes over missing middle housing to avoid water quality regulations, contributing to suburban sprawl and the housing affordability crisis. Insert the following language after line 153: The City Council directs the City Manager to account for differences in the additional cost of compliance resulting from these code amendments between single family homes, small scale missing middle projects and larger multifamily projects, so that such costs are proportionate to the scale of the project, and do not disincentivize the construction of small scale missing middle projects in favor of single family homes. Add the following BE IT FURTHER RESOLVED: BE IT FURTHER RESOLVED: The City Council initiates City Code amendments and directs the City Manager to provide recommendations for changes to the City Code to ensure that the cost of compliance with water quality, drainage, and Site Plan requirements relating to single family homes and small scale missing middle projects is proportionate to the scale of the project, and does not disincentivize the construction of small scale missing middle projects in favor of single family homes, including applying some water quality and drainage requirements to single-family development as proposed during the LDC Revision.
6/9 Item 61 Water Quality CM Vela Amendment 1 - V4 to V5 Additions Bolded Proportionate Standards for Missing Middle Housing Add the following WHEREASes: WHEREAS, small scale missing middle housing projects (projects with approximately 3 to 12 units) are required to comply with the same procedures and requirements for review of water quality protections and site plans as large scale multifamily residential projects, while single family homes are not subject to those requirements, creating an incentive for developers to build single family homes over missing middle housing to avoid water quality regulations, contributing to suburban sprawl and the housing affordability crisis; WHEREAS, a large single family home can actually have more impervious cover than a multi-unit development, and the amount of impervious cover for a project is one of the key factors affecting drainage regardless of project type and should be taken into account when evaluating water quality and drainage requirements for site plans; Insert the following language after line 153: The City Council directs the City Manager to account for differences in the additional cost of compliance resulting from these code amendments between single family homes, small scale missing middle projects and larger multifamily projects, so that such costs are proportionate to the scale of the project and the amount of impervious cover, and do not disincentivize the construction of small scale missing middle projects in favor of single family homes. Add the following BE IT FURTHER RESOLVED: BE IT FURTHER RESOLVED: The City Council initiates City Code amendments and directs the City Manager to provide recommendations for changes to the City Code to ensure that the cost of compliance with water quality, drainage, and Site Plan requirements is proportionate to the amount of impervious cover for a project, and does not disincentivize the construction of small scale missing middle projects in favor of single family homes, including applying some water quality and drainage requirements to single-family development as proposed during the LDC Revision.

WHEREAS, protecting our environment is the foundation for sustaining our planet, community, and economy; and WHEREAS, the City of Austin’s “State of Our Environment: 2020 Annual Report,” showed that creeks in the Desired Development Zone scored on average 10 points lower than those in the Drinking Water Protection Zone; and WHEREAS, the Drinking Water Protection Zone designation located on the west side of Austin has restricted development through regulations creating positive environmental outcomes, while the Desired Development Zone, located in Central and East Austin, has more permissive regulations that have resulted in some negative outcomes; and WHEREAS, properties located in the Desired Development Zone have more permissive development regulations with regard to the size of creek buffers, impervious cover limits, cut and fill, and construction on slopes; and WHEREAS, extensive empirical literature links exposure to nature with better health, and creeks provide city-wide opportunities to experience nature; and WHEREAS, current code allows for structures such as in-channel detention basins and concrete wastewater manholes to be placed in creeks, which can cause erosion and other severe, often long-lasting consequences that can be expensive to reverse; and WHEREAS, the City is faced with the existing and growing threat of industrial discharges that can negatively impact creeks and communities located primarily on the east side of the City of Austin; and Page 1 of 8 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 WHEREAS, there has been a steady increase in the amount of land area in Austin covered by impervious surfaces and a corresponding steady decrease in the amount of pervious land area capable of absorbing rainfall; and WHEREAS, one result of the historically high rates of development is a rise in the amount of runoff that flows off-site from developed properties and into older, undersized stormwater drain systems, creeks, rivers, and lakes, contributing to increases in flooding severity, damage to private property, loss of life, and water pollution; and WHEREAS, currently City Code allows redeveloped sites to use existing impervious cover as a baseline for drainage calculations, resulting in increased runoff and contributing to flooding and erosive flows downstream; and WHEREAS, a U.S. Geological Survey study found that using green …
June 9, 2022 Item 61 Mayor Adler CM Harper-Madison CM Ellis MOTION SHEET I move to amend Item 61 as follows: Insert at Line 35: WHEREAS, increasing density reduces sprawl and thereby reduces traffic congestion, pollution, and development of open spaces and agricultural land; and The City Council initiates other code amendments, as necessary, to Insert at Line 150: accomplish the goals of this Resolution. Beginning at Line 154: The City Manager shall present these code amendments for Council consideration no later than September 15, 2022, except for amendments regarding the greenfield conditions as a baseline for redevelopments and steep slope protections. The City Council directs the City Manager to engage stakeholders and develop recommendations that would seek to offset the impact on affordability and capacity of requiring greenfield conditions as a baseline and steep slope protections on properties where they are not currently required. Offsets could include additional entitlements or waivers for impacted tracts. The City Manager shall present these recommended code amendments for Council consideration no later than December 8, 2022.
June 9, 2022 Item 61 Motion Sheet CM Renteria Amend the Be It Resolved clause beginning at line 163 to read: BE IT FURTHER RESOLVED: The City Council directs the City Manager to conduct an Affordability Impact Analysis and a Fiscal Impact Analysis for each proposed code or process change resulting from this resolution. The City Council directs the City Manager to provide the results of these analyses to Council at least two weeks prior to the implementation of any process change or the presentation of proposed code amendments for Council consideration. The City Council directs the City Manager to include these analyses as part of the Council agenda back up when an item resulting from this resolution is presented to Council for its consideration. Additionally, the City Council directs the City Manager to address the estimated costs of doing nothing to further protect against water pollution, localized flooding, and the heat island effect; of stabilizing creeks and shorelines after scouring and erosive floods; mitigating algae and bacteria in creeks and lakes; and increasing stormwater infrastructure throughout the City.

BRIEFING SUMMARY SHEET DEVELOPMENT ASSESSMENT CASE NUMBER: CD-2022-0001 REQUEST: Presentation of a Development Assessment report for the 517 South Lamar Planned Unit Development (PUD) located at 517 South Lamar Boulevard. The property is located southeast of the intersection of Barton Springs Road and South Lamar Boulevard in the West Bouldin Creek Watershed. DISTRICT: 5 DEPARTMENT COMMENTS: The applicant proposes to rezone a 1.87 acre property from General Commercial Services-Vertical Mixed Use (CS-V) to Planned Unit Development (PUD) zoning. The property is currently developed with commercial land uses including limited retail and medical services. The applicant proposes the property be redeveloped with a 9- story building with approximately 400 multifamily residential units above approximately 10,000 square feet of ground floor mixed commercial land use and underground parking. The proposed rezoning would use CS-V as its base zoning district, with some modifications via the PUD rezoning. The applicant has stated that the project will comply with all Tier One PUD development standards, as well as several Tier Two standards. Tier Two standards proposed include: providing a minimum of 10% of multifamily units for families earning less than 60% of the annual Median Family Income (MFI), placing 95% of parking in a subsurface parking garage, reducing impervious cover, burying overhead utilities along Lamar Boulevard, improving local drainage conditions, utilizing green water quality controls, improved landscaping standards, rainwater irrigation, achieving a 3-star Green Building rating, increased bicycle parking, and other improvements. The applicant proposes the following Code modifications: allow the optional supplemental zone between the building and clear zone to increase from a maximum of 30 feet to 68 feet; allow a building height of 102 feet; waive Compatibility Standards as related to building height; modify scale and clustering requirements; and allow PUD zoning on a site less than 10 acres.

MEMORANDUM TO: Chair and Members of the Environmental Commission FROM: Andrei Lubomudrov Housing and Planning Department DATE: May 25, 2022 RE: Proposed annexation of one property (approximately 5.03 acres) into Travis County Water Control and Improvement District No. 10 (District); case: C12M-2022-0001 On April 13, 2022, the City received an application requesting the City’s consent to the annexation of approximately 5.03 acres located at 4315 Dunning Lane in Austin’s extraterritorial jurisdiction (ETJ) and in the Lake Austin Watershed. The District includes properties in western Travis County and located either in the City of Austin’s ETJ or the City of West Lake Hills. The property to be annexed into the District is located in the Lake Austin Watershed. A map identifying the tract to be annexed into the District and its location relative to existing District boundaries and City jurisdictions is attached. Applicant’s Proposal The applicant seeks annexation into WCID 10 to acquire water service for about half of an existing 10-acre property, or approximately 5.03 acres. If annexation approval is granted, the property owner will subdivide the existing 10-acre property and seek to serve the 5-acre portion of the replatted lot through WCID 10. The balance of the property will be in Austin Water’s service area. As part of the Annexation into a Water District process, case number C12M-2022-0001 will go before Austin’s Commissions as well as Austin City Council. Upon City Council approval, the property will then be annexed by the District. Representatives of the property owners appeared before the District’s Board of Directors at its meeting on January 12, 2022, and the District Board approved the annexation request contingent upon receiving the City’s approval of the District’s annexation of the property. 1 City Review Process The Agreement Concerning Creation of the Travis County Water Control and Improvement District No. 10 (Consent Agreement) requires City approval for the annexation of land by the District. The District is considered a “noncity service district” and as such, the City is not authorized to place restrictions or conditions on this consent. If the City fails or refuses to consent within 90 days of receipt of a written request, the owner may petition the City to make available those services to be provided by the District. Failure to execute a mutually agreeable contract for services within 120 days constitutes authorization for inclusion of land within the District. Requests for annexation into a water …

Austin Ready Mix Wastewater Service Extension Request #5313 What is an SER? • A service extension request, or SER, is an application for City water or wastewater service from a property owner or developer. • SERs are required when a property is located more than 100 feet from an accessible water or wastewater system, or when existing infrastructure isn't adequate for the proposed project demands. • Service may involve the construction of a new line or an associated facility or upgrades to existing lines or facilities. • The applicant pays for the associated infrastructure, as outlined in the SER. SER Process • Per the Land Development Code, SERs require Council approval if the property is in the Drinking Water Protection Zone and outside of the City's full purpose jurisdiction. • Environmental Commission and Water & Wastewater Commission review and make recommendations on SERs that require Council approval. • No conditions can be put on approval of SERs.
