ZONING CHANGE REVIEW SHEET DISTRICT: 1 TO: P CASE: C14-2022-0063 – Walnut Creek WWTP Expansion ZONING FROM: SF-2 ADDRESS: 8001 Delwau Lane SITE AREA: 1.0226 acres (44,546 square feet) PROPERTY OWNER: City of Austin – Water Department AGENT: Rebecca Vento, P.E. CASE MANAGER: Michael Dietz; michael.dietz@austintexas.gov; (512) 974-7617 STAFF RECOMMENDATION: The Staff recommendation is to grant public (P) district zoning. For a summary of the basis of Staff’s recommendation, see the Case Manager Comments section of this report. ZONING AND PLATTING ACTION / RECOMMENDATION: July 19, 2022 CITY COUNCIL ACTION: September 1, 2022 ORDINANCE NUMBER: ISSUES: None at this time. CASE MANAGER COMMENTS: The subject rezoning area consists of one unplatted lot, which is located south of Delwau Lane, near the property at 8400 Delwau Lane, and is currently zoned as single family – standard lot (SF-2). It appears that access to the property was historically taken from an unpaved driveway off of Delwau Lane. However, it should also be noted that the 1995 field notes submitted by the applicant include a sketch that indicates the presence of an “apparent private right-of-way easement” on the west side of the property, near a house that no longer exists on-site, indicating that some site access may have been taken from the adjacent property to the west in the past, as well. 1 of 7B-6C14-2022-0063 Page 2 According to the agent, the existing property features existing infrastructure for the Walnut Creek Wastewater Treatment Plant (“WWTP”), although most of the infrastructure is located below the finished grade. In particular, the subject site features an outfall structure, where a 96’’ subterranean effluent pipe terminates and discharges into the Colorado River. The subject site is mostly rectangular in shape and is currently undeveloped, aside from the aforementioned wastewater treatment infrastructure, most of which is underground. A 5-foot- wide electric easement bifurcates the site, running from the north property line to the east property line. Delwau Lane features a broad range of uses, including residential, commercial, industrial, and public land uses of varying intensities. There is a vehicular racetrack designed for motorsports, although the business operating the track has since closed, located primarily to the northeast. The parcels comprising the track feature different zoning designations (GO, LI, GR, and IP). To the east, more land is owned by the City of Austin and used for the Walnut Creek WWTP (P); this land is also to the northeast due to the unique shape of the lot, which effectively wraps around the racetrack. A vacant parcel intended for commercial uses and allowing mixed uses is located to the west (CS-MU-CO), while single-family residential uses are located further west (SF-2). The subject site abuts the shores of the Colorado River to the south. Please refer to Exhibits A (Zoning Map) and A-1 (Aerial Exhibit). The applicant has requested public (P) district zoning. The existing WWTP outfall structure would be a non-conforming use under the current SF-2 zoning designation. The proposal would realign the zoning for the site to better suit the current use. The applicant has not proposed to alter the existing use. No new development has been proposed for the site. BASIS OF RECOMMENDATION: 1. The proposed zoning should be consistent with the purpose statement of the district sought. Zoning changes should promote compatibility with adjacent and nearby uses. The public (P) district is the designation for a governmental, civic, public service, or public institution use. A P district designation may be applied to a use located on property used or reserved for a civic or public institutional purpose or for a major public facility, regardless of ownership of the land on which the use is located. The proposal would be consistent with the purpose statement of the P zoning district. 2. The requested P zoning would bring the existing WWTP infrastructure into conformity and allow for the expansion of said infrastructure. Staff recommends approval of the applicant’s request because the P district makes sense given the nature of the public-serving use. Furthermore, rezoning the subject parcel to P would eliminate the existing non-conformity of operating the outfall structure in a property zoned SF-2. The proposed rezoning would also add cohesion to the land use pattern in the vicinity of the subject property, as the parcel would be zoned P to match the other public uses in the area. The designation would not cause compatibility issues with the adjacent racetrack use, although the business appears to have 2 of 7B-6C14-2022-0063 Page 3 closed regardless. As such, the proposal would be compatible with the adjacent and nearby uses.

Total Number of “Yes’s” 1 Environmental The site is not located over the Edwards Aquifer Recharge Zone. The site is in the Colorado River Watershed of the Colorado River Basin, which is classified as a Suburban Watershed by Chapter 25-8 of the City's Land Development Code. The site is in the Desired Development Zone. Under current watershed regulations, development or redevelopment on this site will be subject to the following impervious cover limits: Development Classification % of Gross Site Area % of Gross Site Area Single-Family (minimum lot size 5750 sq. ft.)

Based upon the location of the floodplain, offsite drainage should be calculated to determine whether a Critical Water Quality Zone exists within the project location. Standard landscaping and tree protection will be required in accordance with LDC 25-2 and 25-8 for all development and/or redevelopment. At this time, site specific information is unavailable regarding vegetation, areas of steep slope, or other environmental features such as bluffs, springs, canyon rimrock, caves, sinkholes, and wetlands. Under current watershed regulations, development or redevelopment requires water quality control with increased capture volume and control of the two-year storm on site. At this time, no information has been provided as to whether this property has any preexisting approvals that preempt current water quality or Code requirements. Parks & Recreation Department (PARD) – Planning & Design Review There are no parkland dedication requirements associated with this rezoning. Wastewater treatment plant expansion should neither negatively impact adjacent City parkland nor the Colorado River. Site Plan and Compatibility Standards Site plans will be required for any new development other than single-family, two-family or duplex residential. Any new development is subject to Subchapter E. Design Standards and Mixed Use. Additional comments will be made when the site plan is submitted. The site is located within Austin-Bergstrom Overlay Controlled Compatible Land Use Area. No use will be allow that create electrical interference with navigational signals or radio communications between airport and aircraft, make it difficult for pilots to distinguish between the airport lights and others, result in glare in the eyes of pilots using the airport, impair visibility in the vicinity of the airport, create bird strike hazards or otherwise in any way endanger or interfere with the landing, taking off, or maneuvering of aircraft intending to use the Austin-Bergstrom Airport. Height limitations and incompatible uses with each Airport Overlay zone are established in the Airport Overlay Ordinance.
