Project Location Property Data • Austin Full Purpose Jurisdiction • Desired Development Zone • Gilleland Creek Watershed (Suburban Watershed) • Not located over Edwards Aquifer Recharge Zone • No Critical Environmental Features, Wetlands, or Critical Water Quality Zones on site • 5.415 Acres • Council District 1 Variance Request § 25-8-341 - CUT REQUIREMENTS (A) Cuts on a tract of land may not exceed four feet of depth. - The variance request is to allow cut from 4 to 12 feet. § 25-8-342 - FILL REQUIREMENTS (A) Fill on a tract of land may not exceed four feet of depth. - The variance request is to allow fill from 4 to 15 feet. Variance Request • § 25-8-301 - CONSTRUCTION OF A ROADWAY OR DRIVEWAY • (A) A person may not construct a roadway or driveway on a slope with a gradient of more than 15 percent. • - The variance request is to allow roadway on a slope with a gradient of more than 15 percent. • § 25-8-302 - CONSTRUCTION OF A BUILDING OR PARKING AREA • (A) A person may not construct a building or parking structure on a slope with a gradient of more than 25 percent. • -The variance request is to allow building and parking area on slopes greater than 25 percent. Historical Site Usage • Circa 2008 the site was used as a spoils area for nearby road construction which created the increased elevation and steep slopes. Approx. 2003 Approx. 2008 Variance Findings • Variances for grading and construction on slopes have been granted • for projects with similar site constraints, specifically road development guidelines and topographic conditions created from historic use as a spoils site. The variance: • • • Is necessitated by topographic features, not design choice; Is the minimum deviation from the code; and Is unlikely to result in harmful environmental consequences. • Water quality will be equal to water quality without the variance. Staff Determination • Staff recommends the variances having determined the findings of fact have been met, with the following conditions. 1. Contain the fill with a combination of engineered walls and vegetated terraces to reduce steep grading and increase infiltration. 2. Provide three (3) enlarged parking lot islands approximately 17 feet wide for improved tree growth. 3. Provide enhanced tree mitigation with five (5) additional trees that will not be applied to any other environmental requirement. Thank you APPLICANT PRESENTATION
