Lead Department Austin Water Client Department Austin Water Assistant Director of Environmental, Planning & Development Services, Kevin Critendon Fiscal Note There is no anticipated fiscal impact. Prior Council Action October 14, 2021 - Karanam Subdivision (SER-5067) was approved by Council on a 10-0 vote Council Committee, Boards and Commission Action October 19, 2022 - Recommended by the Environmental Commission on a 9-0 vote. November 9, 2022 - To be reviewed by the Water and Wastewater Commission. Additional Backup Information The Karanam Subdivision project consists of approximately 0.62 acres of land located at 10802 D K Ranch Road (the “Property”). The Property is located entirely within the City of Austin’s (the “City”) Limited Purpose Jurisdiction, Impact Fee Boundary, Austin Water’s service area for wastewater, the Drinking Water Protection Zone, and the Bull Creek Watershed. A map of the property location is attached. Applicant: Guru Prasad Karanam (the “Owner”) is proposing to develop approximately two single-family homes. The Owner requested that the City provide wastewater utility service to the Property as proposed in Service Extension Request (SER) No. 5575. The Property is currently developed with an existing single-family home served by an on-site sewage facility (OSSF) and receives City of Austin retail water service. The Owner is proposing to subdivide the Property into two lots and will abandon the existing OSSF. Austin Water will provide retail water service to each proposed single-family home. City Code § 25-9-35 requires City Council approval for this SER because the Property is located within the Drinking Water Protection Zone and outside the City’s full-purpose corporate limits. The City will not cost participate on this project. City Council on October 14, 2021, approved SER-5067 for wastewater service to the Property; however, the previously approved SER expired since the Owner did not submit a development application within the 180-day expiration window (LDC 25-9-39). The proposed development under this current request is identical to the previous request.  Item 16 # 22-3369 Water &Wastewater Commission: November 9, 2022 Council: December 1, 2022 Infrastructure Improvements: To serve the Property, the Owner will be required to construct approximately 400 feet of low-pressure force main from the existing 8-inch gravity wastewater main and extend west along Nashfara Cove and then south along D. K. Ranch Road to the Property. The proposed wastewater improvements are sized to serve the needs of the Property and will conform to all City Code requirements. These improvements will be designed in accordance with City’s Environmental Criteria Manual and Utilities Criteria Manual and will be inspected by the City’s Development Services Department. The Owner will construct all required improvements at their cost and dedicate the facilities to the City for ownership, operation and maintenance. All City fees are applicable to the provision of wastewater service including capital recovery fees. City Staff Recommendation: Austin Water has evaluated the Owner’s request for City wastewater service and can provide centralized wastewater service as proposed in SER-5575. Attached is a report from Austin Water staff outlining additional technical information related to providing service to this tract. Additionally, a report provided by Watershed Protection Department staff that finds no significant environmental concerns with providing centralized wastewater service as proposed in SER-5575 is also attached. Contingent upon approval of SER-5575 for wastewater service to the Property, approval of any related development applications for the Property is subject to current City Code. The proposed project is located in zip code 78759 and is near City Council District 10.

DRAFT MEMORANDUM October 19, 2022 Kevin Ramberg, Chair, and Members of the Environmental Commission Kaela Champlin, Environmental Program Coordinator Watershed Protection Department TO: FROM: DATE: SUBJECT: Karanam Subdivision Wastewater Service Extension Request #5575 Service Extension Requests (SER) located in the Drinking Water Protection Zone and outside of the City of Austin’s full purpose jurisdiction require Council approval and review by the Environmental Commission. Watershed Protection Department staff have completed the review for Karanam Subdivision Wastewater Service Extension Request (SER) #5575 and recommend approval of the request. Site Overview The site consists of a tract of approximately 0.62 acres, located at 10802 D-K Ranch Road. The property is in the City of Austin Limited Purpose Jurisdiction and Council District 10. The site is in the Bull Creek Watershed, Water Supply Suburban, the Drinking Water Protection Zone, and the Northern Edwards Aquifer Recharge Zone. The applicant is proposing to redevelop a single-family home into two single-family homes on two separate lots. A site plan has not yet been submitted to the City of Austin at the time that staff reviewed this SER. The site is currently utilizing an On-Site Sewage Facility (OSSF) and is proposing a wastewater SER with two Living Unit Equivalents (LUEs). An SER was previously approved for this site in 2021 and has since expired. Therefore, the applicant is required to take the SER through the Council and boards and commissions process again. The requested number of LUEs and proposed wastewater infrastructure has not changed. A copy of the August 4, 2021 staff memo (Attachment A) to the Environmental Commission and the Environmental Commission’s recommendation (Attachment B) is included for reference with this memo. 1  Development Impacts Water: The site is located in the Austin Water Service Area. Wastewater: The SER proposes that the applicant construct approximately 400 feet of appropriately sized low pressure force main from the existing 8-inch gravity wastewater main located in Nashfara Cove, and extend west along Nashfara Cove, and then south along D-K Ranch Road to the subject tract, as approximately shown on the attached map (Attachment C). Alternative Wastewater Service: Under Travis County Chapter 448.032(c)(1), each residential unit served by an OSSF is considered a separate structure. Multiple residential units may be on a single lot or site only if the lot or site contains at least one acre of land for each residential unit. A property owner cannot subdivide a single-family lot under one acre unless they have service extended to the site. If service is not extended to the site, the applicant will not be able to subdivide the property and the applicant would not be able to develop with a similar density with decentralized service. Environmental Impacts The property is in the Bull Creek Watershed and is classified as Water Supply Suburban. The site is in the Drinking Water Protection Zone and the Northern Edwards Aquifer Recharge Zone and drains to known Jollyville Plateau salamander (Eurycea sosorum) habitat. The site does not contain critical water quality zone, water quality transition zone, and there are no known critical environmental features on this site. An Environmental Resource Inventory (ERI) was not conducted for this SER. Recommendation Staff review determined that there are no significant environmental risks to extending service to the site. Therefore, the Watershed Protection Department staff recommends support for Wastewater SER #5575. The attached information provides further detail on the applicant’s request. Please feel free to contact Kaela Champlin at (512) 974-3443 or kaela.champlin@austintexas.gov if you have any questions or comments about the proposed SER. cc: Brett Ueno, P.E., Austin Water Colleen Kirk, P.E., Austin Water Liz Johnston, Deputy Environmental Officer, Watershed Protection Department 2  Attachment A ITEM FOR ENVIRONMENTAL COMMISSION AGENDA COMMISSION MEETING DATE: August 4, 2021 NAME & NUMBER OF PROJECT: Karanam Subdivision Wastewater Service Extension Request #5067 NAME OF APPLICANT OR ORGANIZATION: I.T.
