ITEM FOR ENVIRONMENTAL COMMISSION AGENDA COMMISSION MEETING DATE: May 4, 2022 NAME & NUMBER OF PROJECT: Pinnacle at Wildhorse Ranch C8-2021-0152 NAME OF APPLICANT OR ORGANIZATION: Kimley Horn & Assoc., Kevin Burks LOCATION: 12000 Blue Bluff Rd, Austin, TX, 78724 COUNCIL DISTRICT: District #1 ENVIRONMENTAL REVIEW STAFF: WATERSHED: Pamela Abee-Taulli, Environmental Program Coordinator, Development Services Department, 512.974.1879, pamela.abee-taulli@austingexas.gov Gilleland Creek Watershed, Suburban Classification, Desired Development Zone REQUEST: Variance request is as follows: STAFF RECOMMENDATION: STAFF CONDITION: • Request to vary from LDC 25-8-341 to allow cut to 15 feet. • Request to vary from LDC 25-8-342 to allow fill to 15 feet. Staff recommends this variance, having determined the findings of fact to have been met. 1. The applicant will provide enhanced vegetation for the wetland critical environmental features, to be comprised of 1 (one) canopy tree and 2 (two) understory trees per 700 square feet, to be planted in clusters, with plants no closer than 3feet on center, in a generally tree-less area that is roughly 70,000 sf. 2. Grading over 8 feet will be stabilized by containment and/or terracing. 3. Water quality requirements will be met by using biofiltration, a green storm water quality infrastructure. Page 1 of 24Development Services Department Staff Recommendations Concerning Required Findings Project Name: Ordinance Standard: Variance Request: Pinnacle at Wildhorse Ranch Comprehensive Watershed Ordinance as modified by Planned Unit Development (PUD) Ordinance 020214-28 Request to vary from LDC 25-8-341 to allow cut to 15 feet. 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. Grading variances have been deemed appropriate under similar Yes development circumstances for sites with multiple constraints. Blue Bluff/Saddle Ridge at Wildhorse Ranch (C8-2020-0033) also received variances for cut to 15 feet and fill to 15 feet. Both sites have topographical challenges, including slopes near or exceeding a grade of fifteen percent. This site has two wetland features as well. These constraints make it difficult to comply with Transportation Criteria Manual and Americans with Disabilities requirements for slopes, stopping sight distance, and block length maximums without variances to the Land Development Code grading regulations. 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 The variance is not necessitated by a design decision. It is necessitated by the site constraints, including slopes and wetlands. The houses are located on a stretch of flatter area, and the roadway follows the topography, dodging between the steeper slopes. The proposed design preserves the natural drainage patterns by detaining and treating stormwater in multiple basins throughout the property. Page 2 of 24b) Is the minimum deviation from the code requirement necessary to allow a reasonable use of the property; Yes The project has been designed to minimally deviate from the code to allow for accessible routes and crossings in compliance with the Americans with Disabilities Act and in compliance with the Transportation Criteria Manual’s vertical roadway design criteria. The housing and roadways are located on the site so as to maximize use of the flatter areas, and the ponds are located so as to prioritize natural drainage patterns. c) Does not create a significant probability of harmful environmental consequences. Yes With appropriate erosion and sedimentation controls provided in accordance with Code and Criteria, the proposed cut and fill can be managed during construction, despite the slopes and proximity to wetlands. Neither will the completed project create a probability of harmful environmental consequences. 3. Development with the variance will result in water quality that is at least equal to the water quality achievable without the variance. Yes Water quality will be code-compliant and therefore equal to the water quality that would be provided without the variance. In addition, the proposed design preserves the natural drainage patterns by detaining and treating stormwater in multiple basins throughout the property. 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:: 1. 2. 3. The criteria for granting a variance in Subsection (A) are met; N/A The requirement for which a variance is requested prevents a reasonable, economic use of the entire property; N/A The variance is the minimum deviation from the code requirement necessary to allow a reasonable, economic use of the entire property. N/A Staff Determination: Staff determines that the findings of fact have / have not been met. Staff recommends the following condition: 1. The applicant will provide enhanced vegetation for the wetland critical environmental features. Page 3 of 242. Grading over 8 feet will be stabilized by containment and/or terracing. 3. Water quality requirements will be met by using biofiltration, a green storm water quality infrastructure.

City of Austin | Environmental Commission Variance Application Guide 2 Page 9 of 24February 11, 2022 Clearly indicate in what way the proposed project does not comply with current Code (include maps and exhibits) FINDINGS OF FACT Per the attached cut/fill exhibit, there are areas that require cut/fills greater than 4’. As required in LDC Section 25-8-341, in order to grant a variance, the Land Use Commission must make the following findings of fact: Include an explanation with each applicable finding of fact. Project: Blue Bluff at Wildhorse Ranch Ordinance: 25-8-341 Cut Requirements & 25-8-342 Fill Requirements Land Use Commission variance determinations from Chapter 25-8-341 and 25-8-342 of the City A. 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 The otherwise developable land located within the 0% to 15% slope category is primarily comprised of slopes closer to 15%. In order to comply with the Americans with Disabilities Act (ADA) requiring 2% cross slope at intersection crosswalks on the local and collector roadways and to meet Transportation Criteria Manual (TCM) requirements for stopping sight distance (for vertical curves and roadway design) and block length maximums, the proposed grades will need to exceed the cut and fill allowed by Chapter 25. This applies to the single-family lots fronting the roadways meeting the ADA and TCM requirements due to access requirements for the lots. The maximum Cut is 14.7 feet. The maximum Fill is 14.9 feet. In addition, the development of adjacent properties will be challenged by the existing topography. It’s highly likely future developments will be pursuing a cut and fill variance request of this magnitude. We also requested and received City of Austin | Environmental Commission Variance Application Guide 3 Page 10 of 24February 11, 2022 2. similar variances on our Saddle Ridge at Wildhorse Ranch project next door (C8- 2020-0033) due to the same TCM design criteria and ADA requirements that were required as part of that subdivision. 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 b) Yes c) Yes Pinnacle at Wildhorse Ranch is primarily a single-family residential development with roadways and lot layouts generally designed to follow the existing topography to preserve the natural character of the property. In addition, multiple water quality and detention basins have been placed in natural low areas to preserve the existing drainage patterns. We are not changing drainage patterns to route runoff to one basin, and intend to maintain adequate runoff reaching the existing wetland CEFs. This variance request is not driven by a design decision on our side. Is the minimum deviation from the code requirement necessary to allow a reasonable use of the property; Pinnacle at Wildhorse Ranch has been designed to minimally deviate from the code to allow for accessible routes and crossings in compliance with the Americans with Disabilities Act, and meet TCM vertical roadway design criteria. The percentage of the property exceeding 8 feet for this property is 3.4%. Specifically, the design accounts for existing constraints such as the elevation of the adjacent connecting roads at City of Austin approved locations and the minimum allowable roadways slopes to allow for ADA compliance. The roadway network has been designed to minimize the number of cross streets to reduce the amount of cut and fill and to maintain compliance with the Transportation Criteria Manual (TCM) block-length requirement. As such, these cross-streets are required to comply with block length requirements outlined in the code. Does not create a significant probability of harmful environmental consequences. City of Austin | Environmental Commission Variance Application Guide 4 Page 11 of 24February 11, 2022 The proposed roadways and associated drainage system have been designed to protect the natural character and function of the Critical Environmental Features by ensuring they receive the required surface water runoff quantity and quality needed to promote wetland and floodplain health. In addition, the proposed design preserves the natural drainage patterns by detaining and treating stormwater in multiple basins throughout the property. 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 proposed design adheres to all water quality requirements outlined within the Environmental Criteria Manual and as such, will result in water quality that is at least equal to water quality achievable without the variance. In addition, the proposed design preserves the natural drainage patterns by detaining and treating stormwater in multiple basins throughout the property. Based on preliminary discussions with Staff, we are comfortable upgrading from the standard full sedimentation/filtration ponds to green water quality controls as an effort to obtain environmental superiority with this variance request. B. Additional Land Use Commission variance determinations for a requirement of Section 25-8-422 (Water Quality Transition Zone), Section 25-8-452 (Water Quality Transition Zone), Article 7, Division 1 (Critical Water Quality Zone Restrictions), or Section 25-8-368 (Restrictions on Development Impacting Lake Austin, Lady Bird Lake, and Lake Walter E. Long): 1. 2. 3. The criteria for granting a variance in Subsection (A) are met; N/A to this variance request. The requirement for which a variance is requested prevents a reasonable, economic use of the entire property; N/A to this variance request. The variance is the minimum deviation from the code requirement necessary to allow a reasonable, economic use of the entire property. N/A to this variance request. **Variance approval requires all above affirmative findings.
