(Required) to 0 ft. (proposed) to allow for a new boat dock to be built where an existing boat dock already is within the setback on the side property line. Section 2: Variance Findings The Board must determine the existence of, sufficiency of, and weight of evidence supporting the findings described below. Therefore, you must complete each of the applicable Findings Statements as part of your application. Failure to do so may result in your application being rejected as incomplete. Please attach any additional supporting documents. NOTE: The Board cannot grant a variance that would provide the applicant with a special privilege not enjoyed by others similarly situated or potentially similarly situated. I contend that my entitlement to the requested variance is based on the following findings: Reasonable Use The zoning regulations applicable to the property do not allow for a reasonable use because: The existing boat dock was erected before 1984, and needs to be replaced. The current dock does not have enough clearance above the waterline to accommodate modern boats. Rebuilding the dock with an increase in height will allow a reasonable use enjoyed by other homeowners on the lake. Additionally, building a new dock in another location on the waterfront would create an unreasonable impact on the shorefront ecology, wetland biology, and the lakebed that could be avoided by rebuilding in the existing location. Hardship a) The hardship for which the variance is requested is unique to the property in that: The existing boat dock is located immediately adjacent to the neighbor's boat dock, on the property line. The boat dock has been in the same location for more than 40 years. The surrounding wetland is well established and the lakebed is settled around the existing cuts. b) The hardship is not general to the area in which the property is located because: An analysis of 1984 aerial views shows few lots in the area with boat docks. More recently developed lots have built their docks to comply with current setback requirements. City of Austin | Board of Adjustment General/Parking Variance Application 2/9/22 | Page 5 of 8 Item02/4Area Character The variance will not alter the character of the area adjacent to the property, will not impair the use of adjacent conforming property, and will not impair the purpose of the regulations of the zoning district in which the property is located because: The neighbor on the shared lot line also has a non-complying boat dock immediately next to ours. Rebuilding in the same location will not alter the character or use of their property. The use of other nearby conforming properties will not be affected at all. The zoning setback regulations are intended to protect privacy and avoid overcrowding by promoting a feeling of openness. The proposed boat dock, as an accessory structure with few enclosed spaces, will honor the feeling of openness. Privacy screening is built into the design of the proposed dock. Parking (additional criteria for parking variances only) Request for a parking variance requires the Board to make additional findings. The Board may grant a variance to a regulation prescribed in the City of Austin Land Development Code Chapter 25-6, Appendix A with respect to the number of off-street parking spaces or loading facilities required if it makes findings of fact that the following additional circumstances also apply: 1. Neither present nor anticipated future traffic volumes generated by the use of the site or the uses of sites in the vicinity reasonably require strict or literal interpretation and enforcement of the specific regulation because: 2. The granting of this variance will not result in the parking or loading of vehicles on public streets in such a manner as to interfere with the free flow of traffic of the streets because: 3. The granting of this variance will not create a safety hazard or any other condition inconsistent with the objectives of this Ordinance because: 4. The variance will run with the use or uses to which it pertains and shall not run with the site because: City of Austin | Board of Adjustment General/Parking Variance Application 2/9/22 | Page 6 of 8 Item02/5Section 3: Applicant Certificate I affirm that my statements contained in the complete application are true and correct to the best of my knowledge and belief.

(Required) to 0 ft. (proposed) to allow for a new boat dock to be built where an existing boat dock already is within the setback on the side property line. Dear Board Members: 3701 Robbins Rd is within the Limited Purpose Jurisdiction of the City of Austin on the shore of Lake Austin. The site currently contains a new home and an existing non-compliant dock with two boat slips. The dock was constructed on the north property line prior to 1984, and needs to be replaced. The current dock has a clearance of 7’ from the waterline to the bottom of the second level, which does not accommodate most modern boats. We propose building a new dock in the existing location, retaining some existing piles, the existing bulkhead and lakebed cuts, while increasing the overall height of the dock. Increasing the height of the dock will allow for a reasonable use by the homeowner. Below are some photos of the existing dock. Building the new dock in its existing location will have minimal impact on the shoreline and existing wetlands compared to the impact of completely relocating it to comply with current code. In the more than forty years since the boat dock was constructed many waterfront plants, grasses, and trees have grown to maturity. Building a new dock in another location on the waterfront would create impact on the shorefront ecology that can be avoided by rebuilding in the existing location. Rebuilding in the same location will not alter the character or use of the area. This boat dock and the neighbors boat dock are next to each other on the shared property line, and have been for two decades. The use of other nearby conforming properties will not be affected at www.workshopno5.com 5409 Woodrow Ave, Unit C, Austin, TX 78756 Item02/7all. The proposed boat dock will be open and airy with carefully placed screening to allow for privacy. On behalf of the owners, Heidi and Veronica Lew, I ask you to grant this application for a BOA variance. Sincerely, Vani Singal Architect Workshop No.5 LLC www.workshopno5.com 5409 Woodrow Ave, Unit C, Austin, TX 78756 Item02/8ADVANCED CONSULTING ENGINEERS Civil Engineering Consultants, Planners ADV Consulting Engineers, Inc. dba T.B.P.E.

Box 1088 Austin, Texas 78767 Re.: Lew Family Boat Dock 3701 Robbins Road Austin, Texas 78730 Dock Placement Variance Dear Sir; Sincerely, Ashraf T. Ahsanullah, P.E. President at:la This letter is a variance request to allow for placement of proposed dock at the same location as an in-place existing dock. This boat dock site consists of an existing cut in slip with existing boat dock in-place, which will be replaced by the proposed boat same location with same footprint, except for height of dock. Their is an existing bulkhead that satisfies the requirement of lining up the proposed dock placement at the same spot as the existing dock with minimal impact to the lake front. The Site is located in Lake Austin Watershed classified as Water Supply Rural. This allowance would enable the property owners a reasonable use of the property and does not create a significant adverse impact to the lake front, avoids unnecessary bulkhead modifications and offers minimal impact to the lake front environment considering that the dock is located in the FEMA 100 year flood plain and in the Critical Water Quality Zone (CWQZ). Moreover it is a minimum impact change necessary to avoid encroaching into the wetlands just west of the existing dock as per the ERI report if relocating the proposed dock. We look forward to getting this BOA variance approvals from the City of Austin in the spirit of the ordinance.
