This application is for a dock extension of 35% of the channel width. ____________________________________________________________________________ ____________________________________________________________________________ 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 site shoreline borders a cove that's extremely shallow. There's one access path within the ____________________________________________________________________________ cove that's deep enough to be navigable. The rest of the cove is less than 2' deep. So even if ____________________________________________________________________________ the owner were to dredge a navigable dock, a boat couldn't reach the slips unless the dock ____________________________________________________________________________ opens on the access path. Thus the location of the dock is set by the location of the navigable ____________________________________________________________________________ access path. And that dock location extends about 35% of the channel width. However, this site almost exclusively contains both shorelines of the channel. ____________________________________________________________________________ ____________________________________________________________________________ ____________________________________________________________________________ Hardship a) The hardship for which the variance is requested is unique to the property in that: The water is extremely shallow in this location, and the dock has to extend to the lone navigable ____________________________________________________________________________ access path in order to be used. ____________________________________________________________________________ ____________________________________________________________________________ ____________________________________________________________________________ ____________________________________________________________________________ b) The hardship is not general to the area in which the property is located because: The vast majority of dock sites on Lake Austin have sufficiently deep water to be permitted ____________________________________________________________________________ following code limitations. ____________________________________________________________________________ ____________________________________________________________________________ ____________________________________________________________________________ ____________________________________________________________________________ City of Austin | Board of Adjustment General/Parking Variance Application 6/26/20 | Page 5 of 8 ITEM7/4 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: Both shorelines of the channel are located on this property. There is a small section of ____________________________________________________________________________ shoreline off-property, but the dock construction won't prevent a boat from reaching that off-site ____________________________________________________________________________ shoreline. ____________________________________________________________________________ ____________________________________________________________________________ ____________________________________________________________________________ ____________________________________________________________________________ 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: NA ____________________________________________________________________________ ____________________________________________________________________________ ____________________________________________________________________________ ____________________________________________________________________________ 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: NA ____________________________________________________________________________ ____________________________________________________________________________ ____________________________________________________________________________ ____________________________________________________________________________ 3. The granting of this variance will not create a safety hazard or any other condition inconsistent with the objectives of this Ordinance because: NA ____________________________________________________________________________ ____________________________________________________________________________ ____________________________________________________________________________ ____________________________________________________________________________ 4. The variance will run with the use or uses to which it pertains and shall not run with the site because: NA ____________________________________________________________________________ ____________________________________________________________________________ ____________________________________________________________________________ ____________________________________________________________________________ City of Austin | Board of Adjustment General/Parking Variance Application 6/26/20 | Page 6 of 8 ITEM7/5Section 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.

Box 1088 Austin, Texas 78767 Dear Board Members: Re: Engineering Summary Letter for 4625 Rockcliff Road SP-2022-0246D Application for a variance to LDC 25-2-1176(A)(2) to allow construction of a boat dock extending 35% of the channel width. The project titled 4625 Rockcliff Road proposes to construct a two-slip boat dock and new bulkhead on an 11-acre site located about 2 miles north of the intersection of Loop 360 and Westlake Drive. It’s in the Limited Purpose Jurisdiction of the City of Austin on the shore of Lake Austin. A Site Plan application for this project is currently under review with City staff. The first set of City comments has been received, and an update was submitted in response. The proposed dock plan and elevation views are below. 1505 Westover Road ! Austin, Texas 78703 ! www.janissmithconsulting.com ! TBPE Firm No. F-16978 ITEM7/8 4625 Rockcliff Road BOA Variance Application 9/17/22 Page 2 of 3 This application is for a BOA variance to construct a dock extending more than 20% of the channel width. The dock design currently under review extends 35% of the channel width. The property fronts on both a Lake Austin slough as well as an unnamed creek. Please see pictures below. Lake Austin Slough and Approximate Dock Location Unnamed Creek Upstream of Lake Austin 1505 Westover Road ! Austin, Texas 78703 ! www.janissmithconsulting.com ! TBPE Firm No. F-16978 ITEM7/9 4625 Rockcliff Road BOA Variance Application 9/17/22 Page 3 of 3 There’s a single navigable channel in the slough that’s deep enough for a boat to travel. In order to get a boat from the lake to the proposed dock, the dock must access the navigable channel thus the boat dock location is dictated by the navigable channel. The shoreline layout is shown below. Per the FEMA map and COA Property Profile tool, Lake Austin ends just upstream of the proposed dock at which point the channel becomes an unnamed creek. The proposed dock extension won’t hamper access to the 42’ of the Lake Austin channel upstream of the proposed dock location. The proposed boat dock extension leaves a 62’ wide path open for watercraft to travel up the remaining 42’ of slough. However, the canal’s too shallow to be navigable for boats. On behalf of the owners, Ethel and Davd Richards, I ask you to support the variance application to allow them to permit a boat dock on their lakefront property in the only location that’s feasible. I look forward to the meeting on the 10th. Very truly yours, Janis J. Smith, P.E Janis Smith Consulting, LLC 512-914-3729 1505 Westover Road ! Austin, Texas 78703 ! www.janissmithconsulting.com !
