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 ofsimilarly situated property with approximately contemporaneous developmentsubject to similar code requirements.No The property contains uplands that are completely developable without the need for a variance from the Land Development Code. The majority of the parcel can be developed without the additional crossing of the critical water quality zone. Although the private drive crossing the critical water quality zone would allow for more development on the property, the Land Development Code does not provide an allowance for non-complying development of a parcel to maximize the amount of development that can occur on the property. Additionally, an alternative access route from the neighboring property could be available through a joint use access easement. 2.The variance:a)Is not necessitated by the scale, layout, construction method, or otherdesign decision made by the applicant, unless the design decisionprovides greater overall environmental protection than is achievablewithout the variance;No The proposed private drive crossing the critical water quality zone is a design decision made by the applicant. The majority of the property can be developed without the requested crossing of the critical water quality zone. An alternative means of access from a neighboring property could be available. The design decision does not provide greater overall environmental protection. 5 of 34B-07b)Is the minimum deviation from the code requirement necessary toallow a reasonable use of the property;No Access into the property and development of a portion of the uplands is allowed by code, and the proposed development on this portion of the property complies with all code requirements. The secondary proposed private drive crossing the critical water quality zone requires additional variances to the Land Development Code for its construction. c)Does not create a significant probability of harmful environmentalconsequences.No The proposed private drive crossing the critical water quality zone requires additional variances to the Land Development Code for its construction, as well as a significant portion of modification to the 100-year floodplain and restoration and mitigation of impacted wetland critical environmental features. 3.Development with the variance will result in water quality that is at least equalto the water quality achievable without the variance.Yes The proposed private drive crossing the critical water quality zone willhave inlets and storm pipes to collect all stormwater runoff to beconveyed to the water quality and detention facilities on site.B.The Land Use Commission may grant a variance from a requirement of Section 25-8-422 (Water Supply Suburban Water Quality Transition Zone), Section 25-8-452 (WaterSupply Rural Water Quality Transition Zone), Section 25-8-482 (Barton Springs ZoneWater Quality Transition Zone), Section 25-8-368 (Restrictions on DevelopmentImpacting Lake Austin, Lady Bird Lake, and Lake Walter E. Long), or Article 7,Division 1 (Critical Water Quality Zone Restrictions), after determining that::1.The criteria for granting a variance in Subsection (A) are met;No Alternative access routes may be available through a joint use access easement with the neighboring property. Additionally, the construction method proposed requires additional variances to the Land Development Code requirements. 2.The requirement for which a variance is requested prevents a reasonable,economic use of the entire property;No The property contains uplands that are completely developable without the need for a variance from the Land Development Code. Although the private drive crossing the critical water quality zone would allow for more development on the property, the Land Development Code does not provide an allowance for development of a parcel of land to occur without meeting all code requirements, including access. 6 of 34B-073.The variance is the minimum deviation from the code requirement necessary toallow a reasonable, economic use of the entire property.No Access into the property and development of a portion of the uplands isallowed by code, and the proposed development on this portion of theproperty complies with all code requirements. The secondary proposedprivate drive crossing the critical water quality zone requires additionalvariances to the Land Development Code for its construction.Staff Determination: Staff determines that the findings of fact have not been met.

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 ofsimilarly situated property with approximately contemporaneous developmentsubject to similar code requirements.No The portion of fill exceeding four feet and within 100 feet of aclassified waterway is for the construction of two private drives crossing acritical water quality zone. One of these drives is allowed by the LandDevelopment Code, for it is necessary to facilitate the development orredevelopment of a designated corridor or center as recommended in theImagine Austin Comprehensive Plan [LDC 25-8-262(D)(1)]. The other privatedrive crossing the critical water quality zone is not allowed by the LandDevelopment Code and is seeking an additional variance. Were the depth of fillwithin 100 feet of a classified waterway within the four foot restriction of LDC25-8-342, all other areas of fill exceeding four feet in depth but not more thaneight feet on the property would be allowable through an administrativeenvironmental variance.2.The variance:a)Is not necessitated by the scale, layout, construction method, or otherdesign decision made by the applicant, unless the design decisionprovides greater overall environmental protection than is achievablewithout the variance;NoThere are alternative methods of constructing a private drivespanning a classified waterway that would not require fill inexcess of four feet.b)Is the minimum deviation from the code requirement necessary toallow a reasonable use of the property;10 of 34B-07No Alternate methods of construction exist that would not require an amount of fill in excess of that allowed by the Land Development Code. c)Does not create a significant probability of harmful environmentalconsequences.NoThe excess fill will result in modifications to the floodplain, including loss of native vegetation and soils that aid in riparian health and floodplain function. 3.Development with the variance will result in water quality that is at least equalto the water quality achievable without the variance.NoAlternate methods of construction exist that would not require an amount of fill in excess of that allowed by the Land Development Code. The method chosen will result in additional soil within a floodplain area and on a slope that has the potential to be highly erosive and cause sediment deposition in the creek, will contain backfill areas of construction with rock riprap that prevents infiltration of water and the growth of riparian vegetation, and causes additional construction activities in the floodplain to mitigate for the area of floodplain replaced by excess fill material.

The remainder property has slopes exceeding 15% slope. The property ranges in elevation from 565 to 524 MSL. On-site soils are Type D Expansive Clays and is identified as Blackland Prairie. Multiple wetland CEF’s, and Critical Water Quality Zones exist within the site. Fully developed 100-year and 500-year floodplains exist within the site. 27 of 34B-07October 23, 2019 City of Austin | Environmental Commission Variance Application Guide 3 FINDINGS OF FACT As required in LDC Section 25-8-41, in order to grant a variance the Land Use Commission mustmake the following findings of fact: Include an explanation with each applicable finding of fact. Project: Ventura at Parmer Lane Ordinance: 25-8-342 Fill Requirements 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 similarlysituated property with approximately contemporaneous development subject to similarcode requirements.Yes Access is limited to the otherwise developable land located within the 0% to 15% slope category by the CWQZ. In order to comply with the International Fire Code Appendix D, as adopted by Travis County Emergency Service District #12, regarding two points of access to the site and TxDOT driveway spacing criteria, the proposed grades will need to exceed the cut and fill allowed by Chapter 25.2.The variance:a)Is not necessitated by the scale, layout, construction method, or other designdecision made by the applicant, unless the design decision provides greateroverall environmental protection than is achievable without the variance;Yes Ventura at Parmer Lane is a multifamily development generally designed to follow the existing topography to preserve the natural character of the property. In addition, multiple water quality and detention basins have been placed in natural low areas to preserve the existing drainage patterns. Clearly indicate in what way the proposed project does not comply with current Code (include maps and exhibits) Per the attached cut/fill exhibit, there are areas the require fills greater than 4’. 28 of 34B-07October 23, 2019 City of Austin | Environmental Commission Variance Application Guide 4 b)Is the minimum deviation from the code requirement necessary to allow areasonable use of the property;Yes Ventura at Parmer Lane has been designed to minimally deviate from the code to allow for two access points meeting TCESD#12 requirements. The percentage of the property exceeding the allowable cut/fill for this property is 10.6%. Based on input from City staff, the final grades were reduced to below 8ft cut/fill (to minimally deviate from code) by increasing the number of storm sewer culverts under the roadways crossing the CWQZ and while maintaining Drainage Criteria Manual requirements for conveyance of the 100-year storm. c)Does not create a significant probability of harmful environmentalconsequences.Yes The proposed roadways and associated drainage system have been designed to protect the natural character and function of the Critical Environmental Features and Critical Water Quality Zones by ensuring they receive the required surface water runoff quantity and quality needed to promote wetland and floodplain health. The proposed design preserves the natural drainage patterns by detaining and treating stormwater in multiple basins throughout the property. In addition, the proposed design removes the +/-150,000 sf of existing impervious cover located in the CWQZ and restoration of the CWQZ with 609S seed mix and native plantings. 3.Development with the variance will result in water quality that is at least equal to thewater quality achievable without the variance.Yes The proposed design adheres to all water quality requirements outlined within the Environmental Criteria Manual and as such, will result in water quality that is at least equal to water quality achievable without the variance. Biofiltration ponds have been sized to treat all proposed impervious cover on the site. B. Additional Land Use Commission variance determinations for a requirement of Section 25-8-422 (Water Quality Transition Zone), Section 25-8-452 (Water Quality Transition Zone), Article 7, Division 1 (Critical Water Quality Zone Restrictions), or Section 25-8-368 (Restrictions on Development Impacting Lake Austin, Lady Bird Lake, and Lake Walter E.
