3115 Westlake Drive Austin, Texas 78746 Case#C15-2020-0068 D-5/1-PRESENTATIONVARIANCE REQUEST 1. LDC 25-2-551(B) – reduce the Lake Austin shoreline setback on the canal only from 75’ to 15’. 2. LDC 25-2-551(C)(3)(a) – increase the allowed impervious cover from 35% to 40% in a slope category within the 0-15% slope. D-5/2-PRESENTATIONAERIALS D-5/3-PRESENTATIONREASONABLE USE • The property owner is requesting an increase to impervious cover and a shoreline setback as to the canal to accommodate a proposed guest house and related improvements as allowed under LDC 25-2-893(D). To accomplish the same, a variance is being requested. • This is a fair and reasonable use in the Lake Austin zone district, as this district specifically prescribes development that is residential in nature. D-5/4-PRESENTATIONHARDSHIPS • The slough accounts for 16,757 square feet; • The 75’ shoreline setback from the main channel is 12,545.8 square feet; • The 75’ shoreline setback from the slough is 53,612.8 square feet; • The total area of the Property outside of the 75’ setbacks is only 51,213.3 square feet; D-5/5-PRESENTATIONHARDSHIPS CONTINUED • The upper portion of the Property near Westlake Drive is unbuildable due to extensive slope and has an existing driveway that is to remain; • The 75’ setback from the slough extends the entire width of the Property in many areas and only allows for, at the largest, an 18’ wide house; • The length of the Property is approximately 780 feet, while the width is only 167 feet; and • Given the width of the slough and the shoreline setback, the guest house requires a driveway of that extends across more than ¾ of the length of the Property. D-5/6-PRESENTATIONCHARACTER • The proposed construction is limited to a guest house, which is common along Lake Austin. • The existing house and proposed guest house has a lower impact on the area than neighboring properties given the smaller scale of the existing house and proposed guest house. • The construction will be consistent with the various construction styles found throughout Lake Austin. • There will be no adverse impact to adjacent properties.
