BRIEFING SUMMARY SHEET DEVELOPMENT ASSESSMENT CASE NUMBER: CD-2022-0003 – 200 E. Riverside Planned Unit Development REQUEST: Presentation of a Project Assessment Report for the 200 E. Riverside Planned Unit Development, located at 200 East Riverside Drive, within the Lady Bird Lake Watershed and the East Bouldin Creek Watershed. DISTRICT AREA: 9 DEPARTMENT COMMENTS: The Applicant has submitted a project assessment for a proposed professional office and commercial development on 3.9555 acres to be known as the 200 E. Riverside Planned Unit Development (PUD). The banks of Lady Bird Lake are located approximately 160 feet to the northeast at their closest point. The proposed development area presently contains a circa 1970 51,285 square foot, two-story, 30-35 foot tall (vacant) office building with surface parking and has driveway access to East Riverside Drive and “Little” East Riverside Drive, a 60-foot wide private access easement adjacent to the western property line. The property is within the South River City Citizens Neighborhood Plan Area and designated as Mixed Use on the Future Land Use Map. The property is also within the South Central Waterfront subdistrict of the Waterfront Overlay and within the South Central Waterfront Vision Framework Plan district boundaries. The property is currently zoned lake commercial – neighborhood plan (L-NP) district. The Applicant’s proposed rezoning request to PUD-NP consists of a multi-use project that would include two high-rise buildings intended for 1,377,787 square feet of office uses and 29,318 square feet of ground floor, commercial / retail uses with a maximum height of 410 feet. The Applicant does not currently contemplate residential use of the property, although the proposed project could be modified to include it. The PUD will also provide 0.87 acres of open space (including two pocket parks with a cumulative area of 14,893 square feet and open to the public) located between the two buildings that will connect to surrounding park land through a public access easement. A mix of below grade and above grade structured parking is proposed. Vehicular access to the PUD is proposed to occur from one driveway to East Riverside Drive and one driveway to “Little” East Riverside Drive. The Applicant has had conversation with Capital Metro regarding an at-grade train station for the Project Connect Blue Line on “Little” East Riverside Drive. A transportation impact analysis (TIA) will be required at the time a formal rezoning application for PUD-NP is received by the City. The …

Request to vary from LDC 25-8-341 to allow cut over 4 feet up to 8 feet. Request to vary from LDC 25-8-342 to allow fill over 4 feet up to 20.5 feet. Staff recommends this variance, having determined the findings of fact to have been met. Provide 8 additional trees at 3 caliper inches. Provide structural containment of fill with retaining walls. Development Services Department Staff Recommendations Concerning Required Findings Project Name: Ordinance Standard: Watershed Protection Ordinance Variance Request: Oltorf Site Plan To allow driveways on slopes over 15% per LDC 25-8-301 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. The variance will not be providing a special privilege to the applicant. The proposed buildings are similar in size to similarly situated property. Because the property is also subject to Austin’s Commercial Design Standards Ordinance, 40% of the roadway frontage along East Oltorf is required to have building frontage adjacent to the right of way, therefore, the only available driveway access from Oltorf must cross existing slopes which are steeper than 15% gradient 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. Existing site conditions and accessibility regulations require the only available driveway access from Oltorf to cross existing slopes that exceed 15% gradient. b) Is the minimum deviation from the code requirement necessary to allow a reasonable use of the property; Yes. The site is being graded and redesigned as efficiently as possible in accordance with code requirement to provide the required access slopes to minimize …

In an effort to balance the required earthwork and minimize the cut and fill required to the maximum extent practicable, portions of the emergency access road are proposed at the maximum allowable slope for an emergency access road; and the tennis courts are tiered to reduce the amount of grading required for their construction.
