January 12, 2025 Mr. Ryan Soutter Development Services Dept. 6310 Wilhelmina Delco Drive Austin, TX 78752 Re: The Clovis at McKinney Falls (SP-2024-0202D) 6507 McKinney Falls Parkway Variance from LDC 25-8-342(8)(c) Good Day Mr. Soutter, On behalf of the owner, LDG Development, LLC, we are requesting a variance for fill more than eight (8) feet for the Dee Gabriel Collins Road driveway in order to provide a required access to the proposed development The Clovis at McKinney Falls, a multi-family affordable housing project (SP-2024-0202D), located at 6507 McKinney Falls Parkway, south of the intersection of McKinney Falls Parkway and Dee Gabriel Collins Road. The project consists of 264 units spread over 10 buildings, along with the clubhouse and pool. The site is located within the City of Austin 2-Mile Extraterritorial Jurisdiction (ETJ) and was most recently used for two single-family homes. The site is within the Cotton Mouth Creek watershed, a suburban watershed, and is not located over the Edwards Aquifer Recharge Zone. There are no CWQZ, WQTZ, nor CEFs located on the site. The Fire Marshal requires two means of access to the site from different streets, in this case, McKinney Falls Parkway and Dee Gabriel Collins Road. This is so that if one driveway were to be obstructed, the second driveway could be used to service the site. Most of the site is within the 0-15% slope category, but the steeper portions of the site are along the adjacent roadways, meaning that any site driveway must cross steep slopes to gain access to the site. The complication for the Dee Gabriel Collins driveway is that the maximum slope of a fire access roadway is 10%, and when crossing the steeper slopes, a fill condition is required to support the drive. In other words, due to the limit on the driveway slope, the grades driveway cannot keep up with the falling slope of the site and must have fill placed beneath it. Unfortunately, simply due to the existing topography, the fill amount for a small portion of the driveway exceeds the 8-foot limit prescribed by code LDC 25-8-342(8)(c). The maximum proposed amount of fill in this area is about 14.5 feet, and the fill is contained by retaining walls to limit the impact to the site and nearby trees. No other alternative location for the driveway is possible due to the Travis County driveway spacing and sight distance requirements from the intersection of McKinney Falls Parkway and Dee Gabriel Collins Road. The findings of fact are included in the attached Environmental Board Variance application template. We request your support for this variance request, and if you have any questions, please let us know.

The site is within the Blackland Prairie ecological region of Texas(Gould, 1975). Woodland species are predominantly Cedar Elm,Hackberry, Chinaberry, Ashe Juniper, and Mesquite; there are noHeritage Trees on the site.

Project: Ordinance: 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 or the safety of property given to owners of other similarly situated property with approximately contemporaneous development. Yes/No [summary of justification for determination] 2. The variance: a) Is not based on a condition caused by the method chosen by the applicant to develop the property, unless the development method provides greater overall environmental protection than is achievable without the variance; Yes/No [summary of basis for determination] b) Is the minimum change necessary to avoid the deprivation of a privilege given to other property owners and to allow a reasonable use of the property; Yes/No [summary of basis for determination] c) Does not create a significant probability of harmful environmental consequences; and City of Austin | Environmental Board Variance Application Guide 3 The Clovis at McKinney FallsThe second driveway is a fire code requirement and the location of the driveway is mandatedby Travis County Sight Distance requirements from the McKinney Falls Parkway intersection.The fill is contained by a retaining wall to minimize site disturbance and tree removal. Otherthan the unusual amount of fill, the driveway is unremarkable. All other requirements of25-8-342(A)(8) have been met.LDC 25-8-342(A)(8)(c)The fire code requires two driveways to the site from separate streets for redundancy. Therefore, theDee Gabriel Collins Road Driveway, a fire access road, may not have a slope greater than 10% at anypoint. Unfortunately, the existing grades the drive must cross have a steeper slope, resulting in the highfills proposed. Denial of the variance would disallow the entire project since the site would not have therequired two access points.05 SP-2024-0202D - The Clovis at McKinney Falls5 of 16 February 28, 2013 Yes/No [summary of basis for determination] 3. Development with the variance will result in water quality that is at least equal to the water quality achievable without the variance. Yes/No [summary of basis for determination] B. Additional Land Use Commission variance determinations for a requirement of Section 25‐8‐393 (Water Quality Transition Zone), Section 25‐8‐423 (Water Quality Transition Zone), Section 25‐8‐453 (Water Quality Transition Zone), or Article 7, Division 1 (Critical Water Quality Zone Restrictions): 1. The criteria for granting a variance in Section A are met; Yes/No [summary of basis for determination] 2. The requirement for which a variance is requested prevents a reasonable, economic use of the entire property; and Yes/No [summary of basis for determination] 3. The variance is the minimum change necessary to allow a reasonable, economic use of the entire property. Yes/No [summary of basis for determination] **Variance approval requires all above affirmative findings.

By being contained by a wall, the 15-foot fill does not impact the environment anymore than a 8-foot fill would.The driveway slopes into the site and the site's water quality facility.05 SP-2024-0202D - The Clovis at McKinney Falls6 of 16 February 28, 2013 A Exhibits for Board Backup and/or Presentation Please attach and paginate. o Aerial photos of the site (backup and presentation) o Site photos (backup and presentation) o Aerial photos of the vicinity (backup and presentation) o Context Map—A map illustrating the subject property in relation to developments in the vicinity to include nearby major streets and waterways (backup and presentation) o Topographic Map ‐ A topographic map is recommended if a significant grade change on the subject site exists or if there is a significant difference in grade in relation to adjacent properties.
