PLANNING COMMISSION SITE PLAN VARIANCE REQUEST REVIEW SHEET CASE NUMBER: SPC-2020-0121C PLANNING COMMISSION HEARING DATE: 04/26/22 (512) 807-2904 Phone: (512) 974-2711 Renee.Johns@austintexas.gov Drenner Group, PC (Amanda Swor) 200 Lee Barton Dr Suite 100 Austin, TX 78704 90 Rainey St LP/ 92 Rainey Street LP 801 W 5th St Ste 100 Austin, TX 78703 PROJECT NAME: 90 Rainey St ADDRESS OF APPLICATION: 90 Rainey, 610 Davis St, 612 Davis St APPLICANT: AGENT: CASE MANAGER: Renee Johns APPROVED DEVELOPMENT: The applicant currently has an approved site plan. The permit is issued for a high rise development in the Rainey District that includes the following uses: a cocktail lounge, hotel, and multi-family. The applicant is requesting a variance from 25-2-721 E 1 of the Waterfront Overlay. DESCRIPTION OF VARIANCE: The applicant requests a variance from § 25-2-721(E) 1 of the Waterfront Overlay Regulations, which limits exterior mirrored glass and glare producing glass surface building materials. The Land Development Code (LDC) defines mirrored glass as glass with a reflectivity index greater than 20%. The applicant proposes to use glass of a reflectivity index of 25% The Waterfront Overlay variance process requires the applicant to obtain a recommendation from the Small Area Planning Joint Committee and Environmental Commission, before the Land Use Commission. The variance was heard by SAPJC on April 13th, and recommend forwarding the variance request without recommendation to the Planning Commission. SAPJC requested more information from staff/applicant regarding potential impact on adjacent buildings, bird friendly design, transmittance, reflectivity, LEED best practices and energy efficiency. These findings are summarized under the Small Area Planning Joint Committee Recommendation section. Staff and the applicant could not schedule to be heard by the Environmental Commission before the PC Hearing. 25-2-721 A 4 States the Land Use Commission may approve or deny the site plan without a recommendation from the Environmental Commission. SUMMARY STAFF RECOMMENDATION: Staff recommends approval of the variance with conditions: glass ratings are restricted to 25%, 47% transmittance, no more than 0.25 Solar Heat Gain Coefficient rating, and incorporate birdy friendly design elements into site plan with a site plan correction. Before recommending the project for a variance, staff considered whether “the variance is the minimum required by the peculiarities of the tract” [LDC Section 25-2-713(B)(2)]. The peculiarities of the site include:  Site is located in CBD and is required to achieve AEGB rating  Increased reflectivity index coupled with 47% transmittance and a maximum Solar Heat Grain Coefficient Rating of 0.25 allows site to exceed AEGB rating requirement and incorporate components of LEED. The applicant worked with staff to reduce reflectivity, increase energy efficiency, and incorporate several bird friendly design elements to reduce collisions. TOWN LAKE CORRIDOR STUDY Staff considered the Town Lake Corridor Study and the effect of this project. Staff determined there is no adverse impact of this project to the goals of the study. SMALL AREA PLANNING JOINT COMMITTEE RECOMMENDATION: Heard on Wednesday April 13th. The Committee recommend forwarding the variance request without recommendation to the Planning Commission with information pending from staff regarding potential impact on adjacent buildings, bird friendly design, transmittance, reflectivity, LEED best practices and energy efficiency. This is detailed below:  Impact on adjacent buildings – This impact is mitigated by the project’s design elements, including recessed balconies, building articulation, and shifted massing volumes (no continuous, smooth, curved surface to cause glare). 20% to 25% exterior glass reflectance does not produce an exponential increase of glare – this difference is not visibly noticeable to the eye. Additionally, the requested variance at this site is lower than previously approved variances for increasing the reflectivity index in the downtown region.  Bird Friendly Design - 90 Rainey complies with LEED Pilot Bird Collision Deterrence standards. Glass reflectivity is restricted to 13.5% in the LEED-identified “critical compliance zone,” (36’-0” above grade) where LEED standards require less than 15% reflectivity. The entirety of 90 Rainey’s podium, 158’-0”, averages 13.5% reflectivity. The same glass is proposed to be used on the entire project, there will be other materials used to meet this requirement. Additional bird-friendly design elements include a podium overhang to shield the critical zone, fully shielded and/or full cut off landscape lighting, no exterior building-up lighting, and building articulation that reduces the size of the building’s reflective plane. Central Texas is not part of an identified bird migration route.  Transmittance – The applicant has committed to a 47% transmittance level. Transmittance is one of 3 major standards to rate glass and describes how much light is transmitted through a window. Reflective glass limits visible light transmittance (VLT). A 47% transmittance rate allows an appropriate amount of natural light to enter a building, while also reducing glare and the need for window blinds and other interior shading devices.  Reflectivity – Glass performance measures are constantly evolving to reflect new technology and energy efficiency goals. Today, reflectivity is measured via three major standards: percentage reflectivity, percentage transmittance, and solar heat gain coefficient (SHGC). Reflectivity reveals the visible portion of the sun’s energy reflected from the glass. Transmittance measures light transmitted through a window, while SHGC describes how much heat is transmitted. These standards provide a more comprehensive, balanced measure of glass performance, versus solely relying on a reflectivity standard. 90 Rainey’s proposed glass would restrict reflectivity to 25%, 47% transmittance, and no more than .25 SHGC. Consultation with AEGB staff indicated that 30% reflectivity and SHGC below .33 provides a good compromise between reflectivity and energy efficiency standards.  LEED best practices– The project fully complies with the LEED pilot bird collision deterrence program. LEED window requirements for Austin’s climate zone (Zone 2) require that windows have less than or equal to 0.25 SHGC. The proposed project is also achieving a 3-star Austin Energy Green Building Program rating.  Energy Efficiency - SHGC measures how much solar heat is transmitted through a window. A lower SHGC indicates more resistance, or a lower percentage of the Sun’s rays passing through glass. This lower percentage produces a cooling effect. 90 Rainey’s proposed .25 SHGC improves the building’s energy efficiency, as cooling is the dominant need for buildings in Austin. Proposed transmittance levels also improve energy efficiency by reflecting a portion of incoming solar radiation, which limits heat penetration into the building and can potentially lower HVAC usage. ENVIRONMENTAL COMMISION RECOMMENDATION Staff/applicant unable to be heard by the Environmental Commission before the 4/26 Planning Commission. Next available date would be heard would be 5/4. 25-2-721 A 4 States the Land Use Commission may approve or deny the site plan without a recommendation from the Environmental Commission.

April 19, 2022 Via Electronic Delivery Ms. Denise Lucas Planning Development Center 6310 Wilhelmina Delco Dr Austin, Texas 78752 Dear Ms. Lucas: Re: SPC-2020-0121C – Reflectivity Variance Request for the 0.3673-acre property located at 90 Rainey Street in the City of Austin, Travis County, Texas (the “Property”). As representatives of the owner of the Property we respectfully submit this letter and enclosed materials as our request for a variance to LDC §25-2-721(E)(1) to allow glass with up to 25% reflectivity within the Rainey Street Subdistrict of the Waterfront Overlay. The intention of this variance request is to mitigate glare and solar heat gain effects from mirrored glass. The request also allows for superior glass, informed by current performance standards which consider transmittance and solar heat gain alongside reflectivity. The proposed glass will have a positive aesthetic impact on Austin’s skyline and is typical of contemporary construction in an urban center. If the variance is granted, the 25% maximum reflectivity will be restricted to segments of 90 Rainey above a 36’ “critical zone,” adhering to LEED pilot Bird Collision Deterrence standards and other best practices for bird collision deterrence. Additionally, the entirety of the garage podium has a reflectivity index of only 13.5% such that the building’s most reflective segments do not impact the ground-level, pedestrian experience. With this request, the building’s pedestrian scale and urban design remains unchanged, therefore, we believe this variance is consistent with the goals and policies of the Town Lake Corridor Study. The 90 Rainey project will enhance this area’s integration with the Ann and Roy Butler Hike-and-Bike Trail and natural environment of Town Lake. The proposed glass provides a sheen on a pedestrian-focused building that welcomes its residents to Austin’s waterfront. The variance is also reasonable, requesting only the minimum required by the performance needs of the building. Please let me know if you need any more information about this project or this request.

On behalf of our client, we are proposing improvements on a 0.3674-acre site located at 610 Davis Street Street. The proposed improvements include 53-story, mixed-use building and associated utility and streetscape improvements to support the development. The proposed building has 4 levels of below grade parking, 30 levels of hotel space, and 22 levels of residential apartments. No portion of the site is located within the Federal Emergency Management Agency’s 100-year floodplain according to Flood Insurance Rate Map number 48453C0465J, dated January 6, 2016 for Travis County, Texas and incorporated areas. The site is not located within the Edwards Aquifer Contributing Zone or Recharge Zones according to the Texas Commission on Environmental Quality (TCEQ). There are no critical water quality zones or water quality transition zones on-site. There are no critical environmental features located on-site. The site is in both the Lady Bird Lake and Waller Creek (urban) watersheds. The total existing impervious cover on site is 89%, while the proposed site will have an impervious cover of 100%. The site is currently zoned as CBD; the impervious cover limit in this zoning classification is 100%. The development proposed on-site detention and water quality by implementing a detention vault within the garage. The detention vault will capture water from the building’s downspouts, treat it, and use it within the building.
