(C) For a residential use, the site development regulations of the most comparable residential zoning district apply. (D) Except as provided in Subsection (E), this subsection applies to a nonresidential use. (1) For a site less than one acre, the site development regulations of an adjoining zoning district apply for a distance of 100 feet into the site. The minimum lot size requirement of an adjoining zoning district does not apply to a use by the City. (2) For a site of one acre or more, the site development regulations are established by the approval of a conditional use site plan. (E) This subsection applies to a parks and recreation services (special) use.

WAIVER REQUESTS: Please see attached letter from the applicant outlining waiver requests. Please note that these waivers are administrative and are approved by staff. PC action on waivers is not required. SUMMARY STAFF RECOMMENDATION: Staff recommends approval of this site plan because it is compatible with the existing Walnut Creek Wastewater Treatment Plant to the east and aligns with the adjacent public park trail to the north. PROJECT BACKGROUND: The City acquired this 2.92 acre parcel from a private company in 2022 for the purpose of developing this new odor control facility. The property is zoned P (Public) and is located within the East MLK Combined Neighborhood Planning Area. FM 969 Road is classified as a Level 4 street according to the Austin Strategic Mobility Plan (ASMP). The property was previously zoned LI-NP (Limited Industrial); the zone change to P (Public) was approved by City Council on July 24, 2025 under case number C14-2025-0035. The MLK-183 FLUM was industrial, so no NPA was required. This zone change was necessary to accommodate a Major Utility Facilities use.

Date created: 8/20/2025 13 SPC-2024-0349C - AW - Crosstown Tunnel OCF; District 16 of 34August 8, 2024 Ms. Kara Weinstein Public Projects City of Austin Development Services Department City of Austin Permitting Development Center 6310 Wilhelmina Delco Drive, Austin, TX 78752 Subject: Crosstown Tunnel Centralized Odor Control Facility CIP Subproject ID: 6943.027 FDU: 4480 2307 4936 Dear Ms. Weinstein: Crosstown Tunnel Odor Control Facility (the “project”) is a new odor control facility located at 6801 FM Road 969, Austin Texas 78724. The project includes the installation of four biotrickling filters, four activated carbon scrubbers, an electrical enclosure, a water quality pond, and appurtenant improvements to provide odor control treatment for the 96-inch Crosstown Tunnel which passes under the site. The site will add 26,000 square feet of impervious cover due to a new access road, pads for the biotrickling filters, and an 1,440 square foot pre-fabricated electrical enclosure. The City of Austin (Austin Water) will own and operate all improvements. The following items are pertinent to the site plan application. • We request that the requirement for an Environmental Resource Inventory by waived on the grounds that the area has been significantly disturbed in the past by the construction of FM 969 and several buried utilities, and the only proposed construction in the critical water quality zone (CWQZ) is a stormwater pipe that crosses perpendicular to the CWQZ to outfall to Walnut Creek and will be revegetated with native seeding per 609S. The pipe outfalls in an armored section of the creek. • We request that the requirements for an Erosion Hazard Zone Analysis be waived on the grounds that the banks of Walnut Creek at the discharge location are rock armored and therefore not susceptible to erosion. • The project area lies entirely within the 2.92 acre tract is owned by the City of Austin. A copy of the condemnation document is attached for reference. City legal has informed us this document is the legal deed. • The project is located within Walnut Creek Watershed, which is classified as suburban. The project shall be developed, constructed, and maintained in accordance with Chapter 25 of the City of Austin Land Development Code. 8310-1 N Capital of Texas Hwy, Suite 250|Austin, TX 78731 | tel: 512-652-1100 13 SPC-2024-0349C - AW - Crosstown Tunnel OCF; District 17 of 34 City of Austin Crosstown Tunnel Odor Control Facility August 2024 Page 2 • The entirety of the site is located outside of the critical water quality zone and the 100-year floodplain (except the storm outfall), per City of Austin and Federal Emergency Management Agency flood insurance rate maps. Map Number 48453C0470K, dated January 6, 2016. • RSMP has been requested and a feasibility meeting was conducted on June 20, 2024. It was determined that this site is a good candidate for RSMP and will be reviewed under formal site plan review. A discharge permit is being coordinated with TxDOT, who owns the land and will accept the increased flows at the point of discharge. Correspondence with their drainage reviewer is attached for reference. A formal discharge permit will be submitted once finalized. • The entire property is zoned LI-NP, which is consistent with zoning for the type and size of facility proposed for the site. • No project phasing is proposed. • Water quality is being provided by a sedimentation/biofiltration pond sized to capture the new impervious cover, with additional capacity for potential future utility improvements. • No landfill activities (new or closures) are proposed. • No embankments which are six feet or higher in finished height are proposed and no dam safety compliance issues are therefore anticipated. In general, the proposed water quality pond is primarily set into excavations below grade and containment berms are therefore relatively short. • A waiver to 25-7-61 of the land development code (2-year detention) is being requested due to non-erosive conveyance of flow to the discharge point through a system of pipes and rock rip- rap banks in Walnut Creek. The project as designed complies with applicable requirements of the City of Austin Land Development Code with the exceptions noted above. If you have any questions, feel free to call.

To respond to your ques7ons below: • Yes, all of the discharge will be ﬂow from onsite. I am a<aching the NAI report with hydraulic analysis and drainage maps we presented to RSMP for reference. • For clariﬁca7on, the project is for the City of Aus7n and the report will show that the 7ming is oﬀ from peak and will not take up capacity in the creek since we are so far down in the watershed. We appreciate any input and help you can provide to determine path forward for this discharge and agreement. 1 13 SPC-2024-0349C - AW - Crosstown Tunnel OCF; District 118 of 34 Feel free to reach out if you have any addi7onal ques7ons or need any addi7onal informa7on to aid your review.

My colleague Michael typically works with the area oﬃce and coordinates discharge permits. @Michael Pimentel do you know who the best person to talk to about this would be? Some ques7ons/comments: Is this all “onsite” ﬂow coming from the site? Do you have an ex vs pr Q calcula7on to look at? • • Typically TxDOT does not allow an increase of ﬂow into state ROW. This is because we like to preserve of system capacity for future projects and don’t want to be preferen7al with developers. o We can make excep7ons to this policy and I think this would be very logical since the discharge is to the Creek so it isn’t taking up ditch capacity is likely oﬀ peak of the creek ﬂows. • The area oﬃce, or someone from our u7lity team can help with what agreement if any is needed.

Joe, 2 13 SPC-2024-0349C - AW - Crosstown Tunnel OCF; District 119 of 34 We are in the process of designing an odor control facility in South Aus7n along FM 969 on the west side of Walnut Creek and as part of this design the runoﬀ from the site will be picked up in a storm pipe and routed down to Walnut Creek, which is located on TxDOT owned property. The TxDOT property is under an agreement with the City for the Walnut Creek Hike and Bike Trail. We would like to coordinate path forward with what procedures we need to go through to allow the installa7on of the drainage pipe, either through a UIR request or otherwise, as well as conﬁrm NAI to TxDOT property to allow discharges to the creek from the proposed site as we are proposing to apply for RSMP in lieu of structural deten7on.

Box 0188 Austin, Texas 78767 Subject: Crosstown Tunnel Centralized Odor Control Facility 6801 FM Road 969, Austin, Texas 78724 Erosion Hazard Zone (EHZ) Determination Waiver Dear Director: The Crosstown Tunnel Centralized Odor Control Facility (the “project”) is a proposed facility that will siphon and treat odor causing air from the existing wastewater system using bio trickling filters located at 6801 FM Road 969 in Austin, Texas. The proposed layout of the site includes an access driveway, pads with the bio trickling filters, and electrical building, associated utilities, a storm drain pipe, and a water quality pond. The water quality pond and associated outfall pipe are located within the critical water quality zone and will discharge to Walnut Creek via a proposed 36- inch reinforced concrete pipe (RCP). We are requesting a waiver to erosion hazard zone analysis requirements related to LDC 25-7-32 due to the following conditions:  All improves outside of the stormwater discharge pipe to Walnut Creek are well outside the limits of the erosion hazard zone (EHZ) buffer.  Runoff to the main stem of Walnut will be conveyed through a 36-inch reinforced concrete storm pipe (RCP) and is considered non-erodible.  The banks of the main stem of Walnut Creek at the outfall location are rock armored for erosion control and the outfall headwall will contain energy dissipators and tie into the existing armoring to prevent erosion at this point.  Due to the fact that both the outfall pipe and the outfall location into the main stem of Walnut Creek are protected against erosion impacts, the establishment of an erosion hazard zone is not applicable for this site. If you have any questions, feel free to call. 13 SPC-2024-0349C - AW - Crosstown Tunnel OCF; District 121 of 34 Crosstown Odor Control Facility June 18, 2024 Page 2 Sincerely, Ellyn Weimer, P.E CDM Smith Inc.

The pertinent section states, “The City will allow small land developments that meet the following requirements to automatically participate in the RSMP. This participation shall take the form of off-site improvements or payment-in-lieu of detention at the discretion of the Director of the Watershed Protection Department.” This project will participate in RSMP by payment. The site plan referenced above is a commercial development on a 2.922-acre site with an impervious cover increase of 0.463 acres from 0.017 acres (1%) to 0.480 acres (16%). Based on the submitted information, the OD concurs that the runoff changes from the site plan improvements are negligible and should not have an adverse impact on the receiving drainage system. Therefore, RSMP participation is hereby approved. The current RSMP Payment estimate, valid until September 30, 2025, is $91,538.40. This assumes a Construction Cost Component of $72,890.94 and a Land Cost Component of $18,647.46 (the Land Cost Component is based on the land appraisal value of $1,043,651 and the TCAD Geographic ID 0213300301). 13 SPC-2024-0349C - AW - Crosstown Tunnel OCF; District 123 of 34 WLN-RS-2025-0010R_RSMP Approval Letter_AW Crosstown Tunnel OCF_SP-2024-0349C Please return the RSMP Agreement PDF, electronically signed by the property owner, via Adobe Sign.

The State reserves the right to require a new drainage permit in the event of reconstruction or other modification of the highway facility by the State. 6. The State may revoke this permit upon violation of any provision of this permit by the Permittee. 7. Modification/ Termination of Permit – If in the sole judgment of the State it is found at any future time that traffic conditions have so changed that the existence or use of the facility is impeding maintenance, damaging the highway facility, impairing safety or that the facility is not being properly operated, that it constitutes a nuisance, is abandoned, or if for any other reason it is the State’s judgment that such facility is not in the public interest, this permit under which the facility was constructed may be : (1) modified if corrective measures acceptable to both parties can be applied to eliminate the objectionable features of the facility; or (2) terminated and the use of the area as proposed herein discontinued. 8. Use of Right of Way – It is understood that the State by execution of this permit does not impair or relinquish the State’s right to use such land for highway purposes when it is required for the construction or re-construction of the traffic facility for which it was acquired, nor shall use of the land under such agreement ever be construed as abandonment by the State of such land acquired for highway purposes, and the State does not purport to grant any interest in the land described herein but merely consents to such use to the extent its authority and title permits. 9. This permit will become null and void if the drainage facilities are not constructed within six (6) months from the issuance date of this permit. Sincerely, Daniel Fleischman, P.E.
