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. Request Summary • 4.44 acres • 2-Mile ETJ • Slaughter Creek Watershed, Barton Springs Zone • Located in the Edwards Aquifer Contributing Zone • Drinking Water Protection Zone (DWPZ) • Subject to Save Our Springs (SOS) Ordinance Request Summary • Living Unit Equivalent (LUE) is the typical flow that would be produced by a single-family residence located in a typical subdivision. Standard conversions are applied depending on the proposed use to determine the number of LUEs a project will generate. • 82,000² ft warehouse building with 21 LUEs SER #5313 Site Location Austin City Limits Austin ETJ Edwards Aquifer Recharge Zone Edwards Aquifer Contributing Zone Site Location Site Location Limited Purpose 2 Mile ETJ SER #5313 Environmental Impacts • No known Critical Environmental Features • No Critical Water Quality Zone or Water Quality Transition Zones onsite • Does not drain to occupied salamander habitat SER #5313 Proposed Wastewater Extension Map provided by Austin Water Water Service • This SER does not require water service. • There is a 12-inch water main on site to connect to in Circle Drive that would meet the fire and domestic needs for the proposed development.

Watershed Protection Department (WPD) staff have completed the review for 8738 US Hwy 290 West wastewater SER #5313 and recommend the request. Site Overview The site consists of one tract of approximately 4.44 acres, located at 8738 W US 290 Highway in the City of Austin’s 2-mile Extraterritorial Jurisdiction. The applicant is proposing to build an 82,000 square foot warehouse building with 21 Living Unit Equivalents (LUEs).

Environmental Impacts The property is in the Slaughter Creek Watershed, the Barton Springs Zone, the Edwards Aquifer Contributing Zone, and the Drinking Water Protection Zone. The site is subject to the Save Our Springs (SOS) Ordinance. An Environmental Resource Inventory was conducted by the applicant, and no known recharge environmental features or critical environmental features were found on site. The site does not contain a critical water quality zone or water quality transition zone and does not drain to known occupied salamander habitat. Development Impacts Water: The applicant is not requesting a water SER for this site. There is a 12-inch water main on-site to connect to Circle Drive that would meet the fire and domestic needs for the proposed development. 2 Wastewater: The applicant is proposing to construct approximately 810 feet of appropriately size force main from the existing 8-inch gravity wastewater main located in Circle Drive near South Bend Avenue west along …

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. Request Summary • 4.44 acres • 2-Mile ETJ • Slaughter Creek Watershed, Barton Springs Zone • Located in the Edwards Aquifer Contributing Zone • Drinking Water Protection Zone (DWPZ) • Subject to Save Our Springs (SOS) Ordinance Request Summary • Living Unit Equivalent (LUE) is the typical flow that would be produced by a single-family residence located in a typical subdivision.
