ITEM FOR ENVIRONMENTAL COMMISSION AGENDA COMMISSION MEETING DATE: 11/03/2021 Park 183 Buildings 6 & 7 (SP-2021-0072C) Nick Brown, P.E., LDC COUNCIL DISTRICT: 4201 W Parmer Lane, Suite C – 100, Austin, TX 78727 NAME & NUMBER OF PROJECT: NAME OF APPLICANT OR ORGANIZATION: LOCATION: ENVIRONMENTAL REVIEW STAFF: WATERSHED: REQUEST: STAFF RECOMMENDATION: District 2 Tunde Daramola, Environmental Review Specialist Senior, DSD, 512-974-6316, Babatunde.Daramola@austintexas.gov Onion Creek Watershed, Suburban, Desired Development Zone Variance request is as follows: Request to vary from LDC 25-8-342 to allow fill over 4 feet up to 17 feet Staff recommends this variance, having determined the findings of fact to have been met. STAFF CONDITION: Provide structural containment of fill with retaining walls. Development Services Department Staff Recommendations Concerning Required Findings Project Name: Ordinance Standard: Watershed Protection Ordinance / Comprehensive Watershed Park 183 Buildings 6 & 7 Variance Request: Ordinance / Other To allow for fill exceeding 4ft for building construction 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. 2. 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. The style of the building proposes a single finished floor building with a 4 -foot loading dock and flat truck court. In order to facilitate this type of development, significant levelling is required to enhance maneuverability into the loading docks, allowing trucks to operate safely on site. The limits of the fill do extend beyond the building as shown in the cut/fill exhibit but is contained with retaining wall structures designed in conjunction with the building walls, so the building is supported. Prior projects in this industrial development zone had a similar situation. A prime example is Crossroads Logistics Center SP-2021-0015D. Land Use Commission variances were granted to LDC 25-8-341 and 342 to allow cut and fill up to 14.3 feet and 16.5 feet, respectively. 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. The industrial use for this project requires level loading docks, parking, and drive aisles. Effective accessibility to portions of the building would not be achievable without this variance. b) Is the minimum deviation from the code requirement necessary to allow a reasonable use of the property; Yes. There is significant fall across the property which poses challenges with cut/fill for a large single finished floor building. The development requires fill beyond 4ft for an efficient and operable building and site. In order to facilitate this type of development, a minimum deviation from code to allow fill up to 17ft is necessary. Structural containment will also be provided to contain and minimize the amount of fill. c) Does not create a significant probability of harmful environmental consequences. Yes. The variance does not create a significant probability of harmful consequences. The variance is a minimum deviation from code to allow for reasonable use of the property. The fill will be minimized and structurally contained with retaining walls. Retaining walls will also reduce the amount of sloping required to return to existing grade. Development with the variance will result in water quality that is at least equal to the water quality achievable without the variance. Yes. The project is served by an existing water quality/wet pond designed to treat this development. All stormwater run from this site will be captured and conveyed to the existing pond. 3. 1. 2. 3. 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 (Water Supply Rural Water Quality Transition Zone), Section 25-8-482 (Barton Springs Zone Water Quality Transition Zone), Section 25-8-368 (Restrictions on Development Impacting Lake Austin, Lady Bird Lake, and Lake Walter E. Long), or Article 7, Division 1 ( Critical Water Quality Zone Restrictions ), after determining that:: The criteria for granting a variance in Subsection (A) are met; Yes / No [provide summary of justification for determination] The requirement for which a variance is requested prevents a reasonable, economic use of the entire property; Yes / No [provide summary of justification for determination] The variance is the minimum deviation from the code requirement necessary to allow a reasonable, economic use of the entire property. Yes / No [provide summary of justification for determination] Staff Determination: Staff determines that the findings of fact have been met. Staff recommends the following condition: Provide structural containment of the fill with retaining walls. Environmental Reviewer (DSD) Date __ 10/21/2021 _____________________________ Environmental Review Manager (DSD) Mike McDougal Date 10-22-2021 Environmental Officer (WPD) _____________________________ Liz Johnston Date 10-22-2021 September 24, 2021 August 26, 2021 ENVIRONMENTAL COMMISSION VARIANCE APPLICATION FORM Variance Request Letter Park 183 Buildings 6 & 7 4800 Distribution Drive & 7900 Industry Way SP-2021-0072C §25-8-342 Fill Requirements Denise Lucas, Director Planning and Zoning Department City of Austin 6310 Wilhelmina Delco Drive Austin, TX 78752 RE: Dear Ms. Lucas: Please accept the following environmental commission variance application form and supporting materials as our request to allow for fill in excess of four (4) feet for the proposed development of the Park 183 Buildings 6 & 7 site development permit (SP-2021-0072C) located at 4800 Distribution Drive and 7900 Industry Way. The subject project is a 19.128-acre tract of land located within the City of Austin Full Purpose Jurisdiction. The project is located within the Onion Creek Watershed classified by the City of Austin as a Suburban Watershed and is currently zoned LI-CO and is not located within the Edwards Aquifer Recharge Zone. The Park 183 Buildings 6 & 7 site development permit proposes two (2) limited warehousing and distribution facilities totaling approximately 300,000 square feet with associated loading docks, surface parking, and utility connections. Water quality and detention is provided in the existing wet pond designed and constructed with SP- 2016-0360C, Park 183 – Building 2. We have analyzed the existing pond with Atlas 14 rainfall data and have determined the 100-year storm is contained within the pond walls and does not overtop the emergency spillway. City of Austin | Environmental Commission Variance Application Guide 1 September 24, 2021 The property is zoned LI-CO and proposes limited warehousing and distribution facilities. Projects surrounding this development, Park 183 Buildings 1, 2, 3, 5 and Park 183 Fedex, are developed with similar sized buildings ranging between 115,000 SF to 160,000 SF. This project requires a variance for the following code section: Division 5. – Cut, Fill, and Spoil. §25-8-342 – Fill Requirements (A) Fill on a tract of land may not exceed four feet of depth, except: (1) in an urban watershed; (2) in a roadway right-of-way; (3) under a foundation with sides perpendicular to the ground, or with pier and beam construction; (4) for construction of a water quality control or detention facility and appurtenances for conveyance such as swales, drainage ditches, and diversion berms, if: (a) the design and location of the facility within the site minimize the amount of fill over four feet; (b) the fill is the minimum necessary for the appropriate functioning of the facility; and (c) the fill is not located on a slope with a gradient of more than 15 percent or within 100 feet of a classified waterway; (5) for utility construction or a wastewater drain field; or (6) in a state-permitted sanitary landfill located in the extraterritorial jurisdiction, if: (a) the fill is derived from the landfill operation; (b) the fill is not placed in a critical water quality zone or a 100-year floodplain; (c) the landfill operation has an erosion and restoration plan approved by the City; and (d) all other applicable City Code provisions are met. (B) A fill area must be restored and stabilized. (C) Fill for a roadway must be contained within the roadway clearing width described in Section 25-8- 322 (Clearing For A Roadway). The City of Austin Land Development Code allows Land Use Commission Variances per the following: Division 3. – Variances §25-8-41 Land Use Commission Variances. (A) It is the applicant's burden to establish that the findings described in this Section have been met. Except as provided in Subsections (B) and (C), the Land Use Commission may grant a variance from a requirement of this subchapter after determining that: (1) the requirement will deprive the applicant of a privilege available to owners of other similarly situated property with approximately contemporaneous development subject to similar code requirements; (2) the variance: City of Austin | Environmental Commission Variance Application Guide 2 Variance Case Information September 24, 2021 City State ZIP Code Work Phone E-Mail Address Case Name Case Number Address or Location Environmental Reviewer Name Environmental Resource Management Reviewer Name Applicable Ordinance Austin, Texas 78727 512-872-6696 Nick.brown@ldcteams.com Park 183 Buildings 6 & 7 SP-2021-0072C Babatunde Daramola 4800 Distribution Dr. & 7900 Industry Way Watershed Protection Ordinance (WPO) Watershed Name Onion Creek Watershed Classification ☐Urban X Suburban ☐Water Supply Suburban ☐Water Supply Rural ☐ Barton Springs Zone Edwards Aquifer Recharge Zone ☐ Barton Springs Segment ☐ Northern Edwards Segment X Not in Edwards Aquifer Zones Edwards Aquifer Contributing Zone Distance to Nearest Classified Waterway ☐ Yes X No 0.25 Miles Water and Waste Water service to be provided by Austin Water Utility Request Impervious cover square footage: acreage: percentage: The variance request is as follows (Cite code references: 25-8-342 Existing 0 0 0 Proposed 666,468 15.3 80 City of Austin | Environmental Commission Variance Application Guide 4 The site generally slopes from South to North ranging between +/-525 to 503. Slopes vary but do not exceed 15% in any direction except for a man-made drainage swale on the north side of the property. September 24, 2021 Provide general description of the property (slope range, elevation range, summary of vegetation / trees, summary of the geology, CWQZ, WQTZ, CEFs, floodplain, heritage trees, any other notable or outstanding characteristics of the property) 0-15% slopes; 19.13 acres 15-25% slopes; 0 acres 25-35% slopes; 0 acres Over 35% slopes; 0 acres Site vegetation generally consists of tall grasses, weeds, and tree cover. The tree cover is mostly hackberry, mesquite, and chinaberry less than 19-inches in diameter mixed with some dead trees. Soils are composed of surface clays then lean clays, sands and gravels, then Austin Group limestone The site does not have CWQZ, WQTZ, CEF’s, or floodplain identified City of Austin | Environmental Commission Variance Application Guide 5 The site complies with all applicable code except fill exceeding 4-feet depicted on the exhibit included September 24, 2021 Clearly indicate in what way the proposed project does not comply with current Code (include maps and exhibits) FINDINGS OF FACT Project: Ordinance: A. 1. As required in LDC Section 25-8-41, in order to grant a variance the Land Use Commission must make the following findings of fact: Include an explanation with each applicable finding of fact. Land Use Commission variance determinations from Chapter 25-8-41 of the City Code: 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 / No This project lay within an industrial park zoned LI-CO with similar warehouse buildings ranging between 115,000 SF to 160,000 SF in size. The style of building proposes a single finished floor building with a 4-foot loading dock and relatively flat truck court where semi-trucks can maneuver into loading docks. These criteria are necessary for an efficient and operable building and site. Existing slopes on the property eliminate the ability to develop this property with an industrial warehouse building. As noted above, this type of development requires significant leveling to allow trucks to operate on the site. 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; City of Austin | Environmental Commission Variance Application Guide 6 September 24, 2021 Yes / No b) c) The industrial user for this project requires level loading docks, parking, and drive aisles. Without the variance, the property would not be reasonably developed to comply with the LI-CO zoning and uses. It is also noted, accessible access to portions of the building would not be achievable without this variance. The structural engineer has also provided a letter stating the proposed structural system is safer and more reliable. Is the minimum deviation from the code requirement necessary to allow a reasonable use of the property; Yes / No The project is zoned LI-CO and the proposed use is allowed in this zoning classification. The proposed buildings are similar in size to the adjacent developments permitted in this industrial park and designed to limit the departure from the code. It is not possible to design a project with 4-foot loading docks and large single floor buildings without exceeding the allowable fill. The building is supported by the structural design as well as the surrounding retaining walls. These retaining walls are designed to limit the extents of fill and reduce the limits in which fill would otherwise be required to return to existing grade. Does not create a significant probability of harmful environmental consequences. Yes / No The proposed design limits the amount of fill in lieu of earth slopes. By retaining the fill, this will reduce the amount of sloping required to return to existing grade and limit the fill to 8-feet or less. Please reference the previously mentioned structural letter explaining the benefit to the proposed design as support. 3. Development with the variance will result in water quality that is at least equal to the water quality achievable without the variance. City of Austin | Environmental Commission Variance Application Guide 7 September 24, 2021 Yes / No B. N/A 1. 2. 3. This development is served by an existing water quality/wet pond designed and constructed under SP-2016-0360C to treat this development. All storm water runoff from this site will be captured and conveyed to the existing pond. 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. Long): The criteria for granting a variance in Subsection (A) are met; The requirement for which a variance is requested prevents a reasonable, economic use of the entire property; N/A The variance is the minimum deviation from the code requirement necessary to allow a reasonable, economic use of the entire property.

The Federal Emergency Management Agency (FEMA) Flood Insurance Rate Map (FIRM) indicates that the southern portion of the site is mapped as Zone AE (areas within the floodway), Zone A (areas within the 100-year floodplain), and as Zone X-shaded (areas within the 500-year floodplain). The eastern portion of the site is mapped as Zone X-shaded, while the remaining areas of the site are mapped as Zone X-unshaded (areas outside of the 100- or 500-year floodplain). Review of historical aerials indicates that gravel pits appear to have operated on the southern portion of the site in the past, and a quarry was observed to the adjoining southwestern during the field investigation. Ponding was observed in this area during the site investigation; however, due to steep gradients, field delineation was not feasible. The ponding area is identified as W-2 on Exhibit 2 in Appendix B. Additionally, Onion Creek was observed along the southern site boundary. The stream was flowing at the time of the investigation, and due to steep gradient, water depth, and abundant vegetation, the stream was unable to be fully delineated. Onion Creek is identified as W-1 on Exhibit 2 in Appendix B. The pond mapped on the USGS topographic map in the central portion of the site was not observed during the site investigation. It appears that the pond may have been previously filled in. Description of Site Plant Communities Continued… Common species include Indiangrass (Sorghastrum nutans), little bluestem (Schizachyrium scoparium), and tall dropseed (Sporobolus asper). The TPWD’s Vegetation Types of Texas maps the site within the “Other Native and/or Introduced Grasses”. This vegetation type is described as being a mix of native or introduced grasses and forbs on grassland sites or mixed herbaceous communities resulting from the clearing of woody vegetation. This vegetation type is also associated with the clearing of forests and may portray early stages of “Young Forest” vegetation type. Dominant species observed on the site included mesquite (Prosopis glandulosa), live oak illinoinensis), Texas (Quercus virginiana), hackberry (Celtis laevigata), pecan (Carya wintergrass (Nassella leucotricha), and bermudagrass (Cynodon dactylon), and bluebonnet (Lupinus texensis). Additionally, hydrophytic vegetation was observed along the corridor of Onion Creek. Dominant species included bald cypress (Taxodium distichum - OBL), Emory’s sedge (Carex emoryi - OBL), false indigo bush (Amorpha fruiticosa - FACW), box elder (Acer negundo - FACW), and spikerush (Eleocharis sp. - FACW).

The limitations of this ERI should be recognized. In conducting the limited scope of services described herein, certain sources of information and public records were not reviewed. The scope of this ERI was conducted in general accordance with the City of Austin’s Land Development Code (LDC), Section 25-8-121 (A), and the City of Austin Title 30-5. The service’s scope is not intended to be compliant or consistent with the State of Texas Edwards Aquifer Rule (30 TAC 213, Subchapter B; pertaining to Travis County, Texas) or the Texas Commission on Environmental Quality (TCEQ) Edwards Aquifer Protection Program. Field identification of Critical Environmental Features (CEFs) as defined by the COA can be seasonally influenced. Due to seasonal changes, Terracon cannot guarantee areas to exhibit or not to exhibit CEF characteristics at all times of the year. CEF wetlands were evaluated using the USACE 1987 Manual and Great Plains Regional Supplement. The manuals provide assistance for identifying wetlands based on the three criteria discussed. However, the manuals alone may not have provided enough information to document whether or not the three criteria were met. Various physical properties or other visual signs used to evaluate whether the three wetland identification criteria areas were satisfied may not be straightforward, especially in disturbed or problem areas. The manuals also allow the user to visually estimate certain indicators, such as the percentage of area covered by dominant species for the entire community. Terracon did not attempt to identify every possible plant species and did not classify soil types by laboratory methods.
