ITEM FOR ENVIRONMENTAL COMMISSION AGENDA COMMISSION MEETING DATE: Sept. 16, 2020 NAME & NUMBER OF PROJECT: Koenig Lane Commercial SP-2019-0561C NAME OF APPLICANT OR ORGANIZATION: Caitlin Kuglen Kimley-Horn LOCATION: 1512-1/2 W Koenig Lane Austin, Texas 78757 COUNCIL DISTRICT: District # 7 ENVIRONMENTAL REVIEW STAFF: WATERSHED: REQUEST: STAFF RECOMMENDATION: STAFF CONDITION: Jonathan Garner, Environmental Program Coordinator Development Services Department (512) 974-1665 Jonathan.Garner@austintexas.gov Shoal Creek Watershed, Urban Classification, Desired Development Zone Variance request is as follows: Request to vary from LDC 25-8-261 to allow private driveway and parking in a critical water quality zone. Staff recommends this variance, having determined the findings of fact to have been met. Provide ribbon strips in the drive aisle, provide vegetative filter strips throughout the property to capture and treat stormwater runoff, and provide porous concrete for pedestrian paths to reduce overall impervious cover and promote more infiltration on site. Staff Findings of Fact Variance to LDC XX-XX-XXX 1 Development Services Department Staff Recommendations Concerning Required Findings Project Name: Ordinance Standard: Watershed Protection Ordinance Variance Request: Koenig Lane Commercial (SP-2019-0561C) Request to vary LDC 25-8-261 to allow a private driveway and parking lot in a critical water quality zone. Include an explanation with each applicable finding of fact. A. Land Use Commission variance determinations from Chapter 25-8-41 of the City Code: 1. The requirement will deprive the applicant of a privilege available to owners of similarly situated property with approximately contemporaneous development subject to similar code requirements. Yes. LDC 25-8-261 will deprive the property owner of a privilege available to owners of other similarly situated property because the surrounding development (and zoning, LO-MU-NP) is all commercial businesses with similar sized lots and development. Additionally, due to the width and traffic volume along Koenig Drive, on-street parking is not an option. If the applicant is deprived of the privilege to develop this property in context with its current zoning and the surrounding uses, the property will remain vacant and unable to be developed or used in its current condition. 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; Yes. In order for the property to be developed under current zoning regulations and in context with the surrounding uses, the applicant is required to provide a means of vehicular ingress and egress, as well as parking on site. Due to the width and traffic volume along Koenig Drive, on-street parking is not an option. In order to achieve greater overall environmental protection, the applicant is providing a series of vegetated filter strips downgradient of the impervious cover as a means of providing some on-site water quality (page 15, variance packet). For a property this size, and the amount of proposed 2impervious cover, on-site water quality is not a requirement. Additionally, the applicant is reducing the overall proposed impervious cover on the property by providing “ribbon strips” for the driveway and porous concrete for all pedestrian walkways (page 16, variance packet). These two methods result in a total proposed impervious cover amount of 55%, where as much as 70% is allowed. Is the minimum deviation from the code requirement necessary to allow a reasonable use of the property; Yes. The applicant is proposing less impervious cover than allowed (Urban watershed, limited only by zoning regulations-70%) and is providing some on-site water quality treatment that is otherwise not required due to property’s location, size of lot, and amount of proposed impervious cover. Does not create a significant probability of harmful environmental consequences. b) c) Yes. The applicant is providing vegetated filter strips throughout the property that will capture and treat some stormwater runoff before entering the City’s storm sewer infrastructure, as well as provide some infiltration benefits. 3. Development with the variance will result in water quality that is at least equal to the water quality achievable without the variance. Yes. Due to the property’s location, size of lot, and amount of proposed impervious cover, on-site water quality is not required. However, the applicant is providing some on-site water quality controls in the form of vegetated filter strips in order to treat and infiltrate some stormwater runoff on site. Neither a rain garden nor rainwater harvesting are feasible for the project since there is neither an accessible storm drain nor adequate roof drains with an irrigation system or a large enough area for a level spreader. Therefore, the vegetated filter strips method of providing on-site water quality control exceeds the water quality requirement that would be achievable without the variance. B. The Land Use Commission may grant a variance from a requirement of Section 25-8-422 (Water Supply Suburban Water Quality Transition Zone), Section 25-8-452 (Water Supply Rural Water Quality Transition Zone), Section 25-8-482 (Barton Springs Zone Water Quality Transition Zone), Section 25-8-368 (Restrictions on Development Impacting Lake Austin, Lady Bird Lake, and Lake Walter E. Long), or Article 7, Division 1 ( Critical Water Quality Zone Restrictions ), after determining that:: The criteria for granting a variance in Subsection (A) are met; Yes. All criteria in Subsection (A) are met. 1. 32. The requirement for which a variance is requested prevents a reasonable, economic use of the entire property; Yes. The proposed development is consistent with the applicable zoning and is contemporaneous with the surrounding properties. The lot has existed in its current configuration for many years. The property is entirely within the CWQZ; expanding the lot to extend beyond the CWQZ is not possible. This property was rezoned from SF to LO-MU-NP in 2004 [Ord. No. 040513-33A]. Based on the location of the property (fronting Koenig Lane), continued SF use is unlikely. In addition, based on the amount of existing impervious cover on the property (33%), and that proposed (55%), neither the redevelopment exception in LDC 25-8-26 nor the administrative variance option in LDC 25-8-42 are feasible. 3. The variance is the minimum deviation from the code requirement necessary to allow a reasonable, economic use of the entire property. Yes. The applicant proposes an impervious cover amount well below the maximum allowance and on-site water quality treatment that exceeds the minimum requirement of Code. Therefore, this minimum deviation from Code is necessary to allow a reasonable, economic use of the entire property. Staff Determination: Staff determines that the findings of fact have / have not been met. Staff recommends the following condition: Environmental Reviewer (DSD) _____________________________ Jonathan Garner Date: 9/8/2020 Environmental Policy Program Manager (DSD) _____________________________ Mike McDougal Date: 9/8/2020 Environmental Officer (WPD) _____________________________ Chris Herrington Date: 9/9/2020 4Application Form Variance to LDC XX-XX-XXX 5ENVIRONMENTAL BOARD VARIANCE APPLICATION TEMPLATE Insert Applicant Variance Request Letter here.

SUPPORT CONCRETE REINFORCEMENT STEEL WITH CHAIRS OR PRECAST CONCRETE BLOCKS ABOUT 1 INCH BELOW THE BOTTOM OF THE PLANNED CONTRACTION JOINTS. 9. SPACE TRANSVERSE AND LONGITUDINAL CONCRETE CONTRACTION JOINTS (INDUCED CRACKS) AT INTERVALS NOT EXCEEDING 15 FEET. THE CONTRACTION JOINT PATTERN SHOULD DIVIDE THE PAVEMENT INTO PANELS THAT ARE APPROXIMATELY SQUARE, WITH THE LENGTH OF ANY PANEL NO MORE THAN 20 PERCENT GREATER THAN WIDTH. DEPTH OF JOINTS MUST BE AT LEAST ONE-QUARTER OF THE SLAB THICKNESS. THE JOINTS MUST BE SAWCUT AS SOON AS THE CONCRETE HAS HARDENED AND WILL NOT TEAR OR RAVEL WHEN CUT, AND NOT MORE THAN 16 HOURS AFTER PLACEMENT. FREQUENT DEPTH CHECKS OF THE JOINTS BY AN INDEPENDENT QUALITY CONTROL ARE RECOMMENDED DURING THE SAW CUTTING OPERATION. AGENCY 10. EXPANSION JOINTS SHOULD BE USED WHEREVER THE PAVEMENT WILL ABUT A STRUCTURAL ELEMENT SUBJECT TO DIFFERENT MAGNITUDE OF MOVEMENT, E.G., LIGHT POLES, RETAINING WALLS, EXISTING PAVEMENT, STAIRWAYS, ENTRYWAY PIERS, BUILDING WALLS, OR MANHOLES. UNLESS OTHERWISE NOTED. 11. EXPANSION JOINTS SHALL BE SPACED NO GREATER THAN 75' AND SEALED WITH APPROPRIATE SEALANT TO MINIMIZE MOISTURE INFILTRATION INTO THE SUBGRADE SOILS AND RESULTANT CONCRETE DETERIORATION AT THE JOINTS. 12. EXPANSION JOINTS TO RUN CONTINUOUSLY THROUGH CURBS. 13. PROVIDE LOAD TRANSFER AT THE INTERFACE BETWEEN AREAS OF CONCRETE PLACED AT DIFFERENT TIMES USING TIED AND KEYED CONSTRUCTION JOINTS. PLACE CONSTRUCTION JOINTS AT PLANNED CONTRACTION JOINT LOCATIONS. (SEE ACI MANUAL OF CONCRETE PRACTICE, PART 2, FOR FURTHER GUIDANCE.) 14. ALL JOINTS SHOULD BE SEALED IN ACCORDANCE WITH ITEM 360 OF THE CURRENT CITY OF AUSTIN STANDARD SPECIFICATIONS. 15. STAGE PAVEMENT CONSTRUCTION THAT CONSTRUCTION TRAFFIC, INCLUDING CONCRETE TRUCKS, DO NOT TRAVEL ON NEWLY PLACED CONCRETE PAVEMENT UNTIL THE CONCRETE ACHIEVES AT LEAST 75 PERCENT OF THE DESIGN STRENGTH, USUALLY 7 DAYS.
