Staff recommends these variances, having determined the findings of fact to have been met. All construction activities to be completed by barge. 2 of 38B-12Staff Findings of Fact 3 of 38B-12 Watershed Protection Department Staff Recommendations Concerning Required Findings Project Name & Case Number: 3002 Scenic Dr Boat Dock Replacement SP-2020-1025D Ordinance Standard: Watershed Protection Ordinance Variance Request: LDC 25-8-281(C)(2)(b) - To allow construction within 150 feet of a Rimrock and Seep Critical Environmental Features (CEF) . 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. A variance from 25-8-281(C)(2)(b) allowing for construction of a boat dock, shoreline access, and stabilization, has been granted for similarly situated properties with approximately contemporaneous development subject to similar code. 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. An existing noncompliant boat dock is proposed to be brought into compliance. No disturbance of the rimrock or seep CEF is proposed, all proposed construction activities are to occur downgradient of the rimrock/seep CEFs, and construction is to occur from the lakeside by barge. The proposed construction to be performed from a barge provides greater overall environmental protection. Additionally, the applicant is providing wetland plantings along the shoreline that will reduce shoreline erosion and sediment-laden surface runoff from discharging into the lake. b) Is the minimum deviation from the code requirement necessary to allow a reasonable use of the property; 4 of 38B-12Yes. The variance is the minimum deviation from the code requirement to allow for a reasonable use of the property. The code requires a 150-foot critical environmental feature buffer. This buffer is not being reduced. The scope of the variance is limited to allowing construction activities to occur within a critical environmental feature buffer only for the proposed boat dock replacement. c) Does not create a significant probability of harmful environmental consequences. Yes. The variance does not create significant harmful environmental consequences. The construction of the boat dock from barge will not disturb the rimrock or seep critical environmental feature. The applicant is providing wetland plantings along the shoreline that will reduce shoreline erosion and sediment-laden surface runoff from discharging into the lake. 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 result in water quality that is at least equal to the water quality achievable without the variance. The construction activities will not disturb the rimrock or seep critical environmental features. The proposed wetland planting along the shoreline will reduce soil erosion along the shoreline and provide filtration of sediment-laden runoff from upgradient areas, thereby providing water quality that is at least equal to or greater than the water quality achievable without the variance. Staff Recommendation: Staff recommends the variance as the Findings of Fact have been met, with the staff recommended condition that all construction be completed by barge. 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; The requirement for which a variance is requested prevents a reasonable, economic use of the entire property; 1. 2. Yes / No N/A Yes / No N/A 3. The variance is the minimum deviation from the code requirement necessary to allow a reasonable, economic use of the entire property. 5 of 38B-12 Yes / No N/A Staff Recommendation: N/A.

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, there are at least fifteen (15) similarly situated properties on Lake Austin that have received approval from the City to develop a boat dock within a CEF Buffer, examples as follows: 3307 Far View Drive (SP-2011-0279D) 3311 Far View Drive (SP-2011-0242D) 3319 Far View Drive (SP-2010-0015DS) 3337 Far View Drive (SP-2014-0135D) 3825 Westlake Drive (SP-2017-0032DS) 3811 Westlake Drive (SP-2016-0185DS) 3909 Westlake Drive (SP-2015-0232DS) City of Austin | Environmental Commission Variance Application Guide 3 12 of 38B-12May 26, 2020 8. 9. 3715 Westlake Drive (SP-2014-0182D) 2806 Scenic Drive (SP-2015-0202DS) 10. 70 Pascal Lane (SP-2014-0144D) 11. 2415 Big Horn Drive (SP-2014-0212DS) 12. 2908 Scenic Drive (SP-2013-0295DS) 13. 3213 Smoky Ridge (SP-2012-0366DS) 14. 5 Humboldt Lane (SP-2013-0133D) 15. 3919 Westlake Drive (SP-2018-0320DS) 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) c) Yes, the property owner is requesting to replace the nonconforming boat dock. No disturbance of the canyon rimrock CEF is proposed, providing greater overall protection for the rimrock with all proposed construction activities occurring downgradient of the rimrock CEF, and from the lakeside by barge. The proposed construction to be performed from a barge provides greater overall environmental protection since there would be no construction on the slopes. Is the minimum deviation from the code requirement necessary to allow a reasonable use of the property; Yes, there is an existing boat dock and this application for the replacement of it. Does not create a significant probability of harmful environmental consequences. Yes, all work would be performed by barge and would have no significant probability of harmful environmental consequences.

City of Austin | Environmental Commission Variance Application Guide 4 13 of 38B-12May 26, 2020 B. N/A N/A 1. 2. 3. Yes, the construction activities will not reduce or disturb the terrestrial vegetation that is providing stabilization of the native soils and preventing soil erosion, thereby, providing water quality that is at least equal to the water quality achievable without the variance. 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 25-8-652 (Development Impacting Lake Austin, Lady Bird Lake, and Lake Walter E.
