Development Services Department Staff Recommendations Concerning Required Findings Project Name: Stillwater-Double Creek Phase 2 | SP-2021-0178C | 10801 Brezza Ln Ordinance Standard: Watershed Protection Ordinance Variance Request: Request to vary from LDC 25-8-261 to allow development in the critical water quality zone. Land Use Commission variance determinations from Chapter 25-8-41 of the City Code: 1. The requirement will deprive the applicant of a privilege or the safety of property given to owners of other similarly situated property with approximately contemporaneous development; The lot is zoned Commercial-Mixed Use, CS-MU-CO as are most of the Yes surrounding lots. A similar existing multifamily development built in 2017 is located directly North of the Stillwater – Double Creek Phase 2 project lot. Without a variance to LDC-25-8-261, the applicant is deprived a privilege to develop this property given to the owners of similarly situated property with approximately contemporaneous development. 2. The variance: a. Is not based on a condition caused by the method chosen by the applicant to develop the property, unless the development method provides greater overall environmental protection than is achievable without the variance; Yes The variance is necessitated by fire department ingress/egress requirements set forth in the International Fire Code and Wildland-Urban Interface. Two points of emergency ingress and egress are required, and AFD will not accept both to be on Brezza Lane which is currently a dead-end street. There is no other option for a second point of ingress/egress. b. Is the minimum change necessary to avoid the deprivation of a privilege given to other property owners and to allow a reasonable use of the property; and Yes As mentioned above, the variance is necessitated by the fire department requirement of having two points of emergency ingress/egress, which will be a bridge crossing and is considered a minimum deviation from the code. c. Does not create a significant probability of harmful environmental consequences; and 7 of 34B-8 Yes The proposed improvements related to the variance do not create a significant probability of harmful environmental consequences. The CWQZ will be crossed by a span bridge design instead of the normal box culvert. This will allow for light to penetrate to the natural ground surface and for vegetation to grow thus maintaining a more natural stream channel. 3. Development with the variance will result in water quality that is at least equal to the water quality achievable without the variance. Yes The variance will not decrease the overall water quality associated with the development. The plans will be fully code compliant for water quality treatment. The impervious cover limit in suburban watersheds is 60%; this project is proposing impervious cover of approximately 44%. Internal, low-traffic pedestrian paths will be constructed with permeable material to increase stormwater infiltration and baseflow in the stream channel. Developed runoff will be treated by the proposed onsite water quality ponds. The Land Use Commission may grant a variance from a requirement of Article 7, Division 1 ( Critical B. Water Quality Zone Restrictions ), after determining that: Additional Land Use Commission variance determinations for a requirement of Article 7, Division 1 (Critical Water Quality Zone Restrictions): 1. The criteria for granting a variance in Subsection (A) are met; Yes / No All criteria in Subsection A are met. 2. 3. The requirement for which a variance is requested prevents a reasonable, economic use of the entire property; Yes / No The proposed development is consistent with the applicable zoning and surrounding properties. Austin Fire Department requires two ingress/egress locations. Brezza Lane is not acceptable for both as it is a dead-end road with no immediate plans to be extended. The North end of the site is dense trees and is proposed to be preserved as parkland. No joint use access agreement with a neighboring property for ingress/egress through to I35 is feasible. The variance is the minimum deviation from the code requirement necessary to allow a reasonable, economic use of the entire property. Yes / No The variance is necessitated by the fire department requirement of having two points of emergency ingress/egress. The emergency ingress/egress proposed across the CWQZ will be a bridge crossing and is considered a minimum deviation from the code. Staff Determination: Staff determines that the findings of fact have been met. Staff recommends the following conditions: 1) Internal low-traffic pedestrian walkways throughout the site shall be constructed with permeable pavers or porous pavement in accordance with the Environmental Criteria Manual, 8 of 34B-8to decrease overall impervious cover and increase stormwater infiltration onsite and baseflow in the stream channel. 2) The critical water quality zone will be crossed with a span bridge design instead of the normal box culvert. This will allow for light to penetrate to the natural ground surface and for vegetation to grow thus maintaining a more natural stream channel.

City of Austin | Environmental Commission Variance Application Guide 5 14 of 34B-8 Site Summary Variance Request for Double Creek Multifamily Phase 2 (SP-2021-0178C) August 31, 2021 Environmental Commission and Land Use Commission City of Austin 301 W 2nd Street Austin, Texas 78701 Re: Dear Commissioners, In order to provide safe emergency access and with minimal disturbance, a variance to Land Development Code § 25-8-261, which limits development in a critical water quality zone, is hereby requested for Double Creek Multifamily Phase 2 site plan (case number SP-2021-0178C) and the related off-site water main improvements per SER-4280. I. The Double Creek Multifamily Phase 2 project is located approximately 1,300-ft north of the intersection of E FM 1626 Rd and Old San Antonio Road, and is on Lot 3 of Double Creek Subdivision, Section 2, Austin, Travis County, and is in the City’s full purpose jurisdiction. The site is zoned CS-MU-CO, per zoning case number C14-03-0053. The project will consist of 371 multifamily units in three to four-story buildings, with surface and garage parking. Water quality ponds, driveway and fire access, utilities, grading, sidewalks, landscaping, approximately 5.5-acres of parkland dedication, and a culvert crossing will be included. The site is 16.00 acres, with right-of-way frontage along Brezza Lane, for which road improvements are currently under construction (SP-2019-0161D). One point of driveway access will be on Brezza Lane. The site will also have access from I-35 via a private drive currently under construction with the site plan Double Creek Multifamily (SP-2018-0403C) and Private Roadway easement doc. no. 2018093713 and a proposed joint use access easement of similar alignment. The private drive will provide access the subject site via a proposed culvert crossing over an existing engineered channel. The property is in the Onion Creek watershed, which is classified as a Suburban Watershed, and is outside of the Edwards Aquifer Recharge Zone. No portion of the site is within the 100-year floodplain, per FEMA map number 48453C0595k, dated January 22, 2020. The site is currently undeveloped with existing impervious cover of 0%, and the proposed impervious cover is less than 50% of the site area. The site currently surface drains from north to south and developed runoff will be treated with proposed water quality ponds and discharge into an existing engineered channel along the south boundary of the site. 5113 Southwest Parkway, Suite 260, Austin, Texas 78735 T: 512.899.0601 Firm Registration No. F-786 www.malonewheeler.com 15 of 34B-8 During the completeness check review for Double Creek Phase 2, the City provided a comment report in June 2021 in which it was stated that a critical water quality zone is delineated about the engineered channel that was constructed in recent years (dates provided in the timeline in Part II below). Emergency and tenant vehicle access to the site is proposed with a culvert crossing over the channel. A portion of a proposed public water main as required by SER-4280 and a water meter will be within 50-ft of the centerline of the channel. These improvements would not explicitly be in compliance with LDC 25-8-261. II. Variance The basis for the variance request and substantiation for its approval is as follows: A. Under § 25-8-41 Land Use Commission Variances, the following apply 1. Subsequent to the construction of the engineered channel, which was permitted in July 2015 under case number SP-2014-0103D “Stablewood Box Culvert,” two site plans in the immediate vicinity were approved and permitted without identifying the artificially engineered channel as a critical water quality zone: i. ii. Double Creek Multifamily Phase 1 (SP-2018-0403C) Brezza Lane Improvements (SP-2019-0161D) The two projects listed above include substantial improvements in the critical water quality zone, including apartment buildings, pavement for parking, utilities, and public roadway. Therefore, under § 25-8-41 Land Use Commission Variances, the requirement will deprive the applicant of a privilege available to owners of other similarly situated property with approximately contemporaneous development subject to similar code requirements. 2. The variance: (a) is not necessitated by the scale, layout, construction method, or other design decision made by the applicant, unless the design decision provides greater overall environmental protection than is achievable without the variance; (b) is the minimum deviation from the code requirement necessary to allow a reasonable use of the property; and (c) does not create a significant probability of harmful environmental consequences; and 3. The surface run-off from the improvements will be treated with city standard water quality facilities and is therefore equal to the water quality achievable without the variance. Additional Substantiation 1. Austin Fire Department requires two points of ingress and egress. The applicant met with AFD on 3/17/2021 and has had follow up correspondence via email, from which the following statements were provided by AFD explaining the code related to the requirement: B. Firm Registration No. F-786 www.malonewheeler.com 16 of 34B-8 Brezza Lane is a dead-end street and the project is located directly in a Wildland Urban Interface (WUI) area which is susceptible to wildfires making fire access and evacuation of the development critical during a structure fire or wildfire event. 2015 IFC: 503.1.2 Additional access. The fire code official is authorized to require more than one fire apparatus access road based on the potential for impairment of a single road by vehicle congestion, condition of terrain, climatic conditions or other factors that could limit access. 2015 Wildland Urban Interface Code Amendments (these direct you back to the fire code). 402.1.1 Access. A subdivision described in City Code Chapter 25-4 (Subdivision) that is located within in a wildland-urban interface area and platted after the effective date of this code must provide fire apparatus access roads that comply with the Fire Code. 403.3 Fire Apparatus Access Road. When required, a fire apparatus access road must Comply with the Fire Code. 2. Timeline of key dates described herein: • • • • July 2015: Stablewood Box Culvert project receives permit (SP-2014-0103D). Construction of the engineered channel begins. See the attached excerpt from the culvert plans, showing the location of the channel improvements. • March 2019: Water SER-4280 is provided by Austin Water, which includes a water service connection and public improvements in the buffer area defined by the CWQZ. SER-4280 is included as an attachment. June 2019: Double Creek Multifamily Phase 1 receives permit (SP-2018-0403C) with meaningful improvements such as buildings and parking within the recently identified critical water quality zone. The Phase 1 Overall Site Plan is enclosed. • August 2020: Brezza Lane Improvement Plans receive permit (SP-2019-0161D) with the portions of the public roadway now in the critical water quality zoned created by the human-constructed channel. June 2021: The CWQZ delineation is brought to our attention via the site plan completeness check comments. July 2021: Site Plan submitted formally to the City (SP-2021-0178C) with no buildings within the recently identified CWQZ. Firm Registration No. F-786 www.malonewheeler.com 17 of 34B-8 • August 2021: Applicant revised the site plan to further minimize encroachment, specifically removing parking from the CWQZ; the only remaining improvements within the recently-identified CWQZ are the required bridge for emergency services and the water meter that is required by the Service Extension Request. III. Conclusion In response to the City’s determination of the critical water quality zone, the applicant has modified the site plan to remove 27 parking spaces and shifted utilities away from the engineered channel to the fullest extent practical. Taken in the aggregate, this variance request is logical and reasonable, and will create an outcome that meets the criteria set forth in § 25-8-41 Land Use Commission Variances, and will meet the requirements set forth by Austin Fire Department.
