THEREFORE, the Environmental Commission recommends the variance request with the following; 1. Applicant will stockpile and preserve topsoil for reuse in landscape, wetland mitigation, and/or biofiltration areas. Staff Condition: VOTE 9-0 For: Smith, Thompson, Neely, Coyne, Maceo, Ramberg, Guerrero, Gordon, Bedford Against: None Abstain: None Recuse: None Absent: Creel, Nill Approved By: Linda Guerrero, Environmental Commission Chair 1 2 of 38B-2Development Services Department Staff Recommendations Concerning Required Findings Project Name: Ordinance Standard: Watershed Protection Ordinance Variance Request: Applied Materials Logistics Service Center Vary from LDC 25-8-341 to allow cut to 12 feet 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. 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 applicant intends to combine multiple warehouses into one consolidated warehouse at this location. Automated robotic equipment and human operated wheeled equipment to be used in the facility require a consistent floor elevation. The applicant proposes 699,000 square feet of warehouse space with a consistent floor elevation, as well as loading docks, fire lanes, and parking that will be constructed at elevations appropriate for the warehouse finished floor elevation. A consistent floor elevation is necessary for this type of automated warehouse. The applicant proposes to construct this facility on a site with minimal slopes (2% to 5%). However, the size of the warehouse necessitates cut up to 12 feet to achieve a consistent finished floor elevation. The applicant proposes cut up to 12 feet, which has been minimized by use of a retaining wall, as shown in Exhibit 1. 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; Yes The materials handling needs of the warehousing process, and inclusion of a large automated storage solution within the warehouse, require a single building with a uniform finished floor elevation. November 4, 2020Page 23 of 38B-2The finished floor elevation was based on 1) working around the CEF, 2) maintaining circulation to the existing campus, and 3) keeping the truck court slopes minimal for maneuverability. Cut to 12 feet is necessary in the south truck bay to maintain a standard 4-foot dock height. In addition, the applicant has selected a relatively flat site for the proposed warehouse. The selection of this site has helped to minimize the required grading. b) Is the minimum deviation from the code requirement necessary to allow a reasonable use of the property; A retaining wall on the west side, parallel to Giles Yes Lane, minimizes the extent of cut adjacent to the building. The truck court grades slope with the natural contours as much as possible while maintaining minimal slopes to facilitate the maneuverability and circulation of the truck traffic. The applicant has selected a relatively flat site for the proposed warehouse, helping to minimize the required grading. c) Does not create a significant probability of harmful environmental consequences. Yes The development process does not pose a probability of harmful environmental consequences. The site is relatively flat, with a slope 2-5%. Based on the gentle slopes and the proposed construction activities, standard temporary and permanent erosion and sedimentation controls will contain sediment in accordance with Code and Criteria requirements. The project will not impact any heritage trees. No floodplain or creek buffers exist within or adjacent to the limits of construction. The project has been designed to incorporate and enhance an existing wetland critical environmental feature. The wetland is the site of an old stock pond and is very low in vigor, density and diversity. Proposed enhancements to the wetland area exceed the mitigation requirement. 3. Development with the variance will result in water quality that is at least equal to the water quality achievable without the variance. Yes The development process does not pose a probability of harming water quality. 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 November 4, 2020Page 34 of 38B-2Water 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:: 1. The criteria for granting a variance in Subsection (A) are met; 2. 3. Yes / No NA Yes / No NA Yes / No NA The requirement for which a variance is requested prevents a reasonable, economic use of the entire property; The variance is the minimum deviation from the code requirement necessary to allow a reasonable, economic use of the entire property. Staff Determination: Staff determines that the findings of fact have / have not been met.

Existing 2,196,631 50.43 47.63 Proposed (total after development) 3,061,581 70.28 66.39 The project is located on the Applied Materials Harris Branch Campus. The Logistics Service Center (LSC) project will be developed as a Unified Development with the portion of the campus located south of Lake Bluebonnet; the Gross Site Area is 105.87 acres. Approximately 21.63 acres of the 44.5‐acre limits of construction are undeveloped; the remaining area consists of overflow parking for the existing manufacturing/ office buildings. The site is located within the Decker Watershed, which is classified as a suburban watershed. No portion of the project limits of construction is located within the limits of the 100‐year floodplain or Critical Water Quality Zone. Topography of the project limits of construction ranges from 610 to 634 feet AMSL. Drainage on the site generally slopes to the east at 2‐5%. Undeveloped portions of the site consist of grasslands with very few trees. No heritage trees are located within the limits of construction. A stock tank is located on the eastern portion of the undeveloped area; the stock tank has been classified as a wetland CEF and will be protected with this project. The existing CEF is very low in vigor, diversity, and density and will be revegetated with the LSC project with a diverse selection of plants. City of Austin | Environmental Commission Variance Application Guide 2 Request Impervious cover square footage: acreage: percentage: 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) November 4, 2020Page 28 of 38B-2 Clearly indicate in what way the proposed project does not comply with current Code (include maps and exhibits) Construction of the LSC project will require limited areas of cut exceeding four (4) feet. Cut between 4’ and 8’ will be limited to an area within the north and south truck courts totaling 1.5 acres, which is 3.38 percent of the 45‐acre limits of construction and 1.44 percent of the gross site area. Cut between 8’ and 12’ will be limited to a 0.87‐acre area within the south truck court, which is 1.93 percent of the 45‐acre limits of construction and 0.82 percent of the gross site area. FINDINGS OF FACT 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. Project: Applied Materials Logistics Service Center Ordinance: 25‐8‐341 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 similarly situated property with approximately contemporaneous development subject to similar code requirements. YES / No The Logistics Service Center (LSC) will include construction of a 729,000 square foot single-story building consisting of 699,000 square feet of warehouse and 30,000 square feet of supporting office space. The project will consolidate seven (7) off-site logistics facilities into one central warehouse and distribution service center. The variance request is common for large facilities of this type in this part of Austin; without this variance the Applicant would be deprived of privileges available to owners of similar projects. The building configuration and placement on the property was based on the location of a wetland Critical Environmental Feature (CEF) that exists on the site. The building was designed to wrap around this CEF so that the wetland could be preserved to the maximum extent possible. Working around the CEF dictated the buildable area for the significant building footprint. City of Austin | Environmental Commission Variance Application Guide 3 November 4, 2020Page 39 of 38B-2The variance: a) The materials handling needs of the warehousing process and inclusion of a large automated storage solution within the warehouse requires the finished floor elevation to be a uniform elevation. The finished floor elevation was based on preserving the wetland and maintaining grades in the area adjacent to the CEF as much as possible. The finished floor elevation of the LSC was also based on the need for the north shipping/ receiving dock to tie-into the existing Applied campus at closely matching elevations. The LSC provides warehousing and distribution support for the six (6) existing manufacturing buildings located on the campus making the seamless connection into the existing campus extremely important for site circulation. For the aforementioned reasons of working around the CEF and maintaining circulation to the existing campus, the warehouse finished floor elevation was set at 625. The north and south truck courts are at an elevation of 621 to maintain a standard 4’ dock height. Areas of cut in excess of 4’ are limited to the two truck courts due to required dock heights. The primary area of cut is near the southwest corner of the building within the south truck court. 2. 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 / No [provide summary of justification for determination] The building configuration and placement on the property was dictated by the location of a wetland Critical Environmental Feature (CEF) that exists on the site. The building was designed to wrap around this CEF so that the wetland could be preserved to the maximum extent possible. Working around the CEF dictated the buildable area for the significant building footprint. The scale, layout, and overall design of the site is based on the need to consolidate seven (7) off-site facilities to one central on-site location to reduce vehicle miles and increase the efficiency of the LSC. This consolidation results in greater overall environmental protection than is achievable without the variance because approximately 84,000 vehicle miles are eliminated annually, yielding:  Less traffic congestion;  Substantial air quality benefits due to the reduction in carbon dioxide and greenhouse gas emissions;  Water quality benefits due to the reduction in hydrocarbons, heavy metals and TSS from fuel, oil and particle laden runoff from roadways; and Reduced noise pollution  The building will consist of a 729,000 square foot warehouse with 9 dock doors and a truck court on the south side of the building and 38 dock doors and a truck court on the north side of the building. The materials handling needs of the warehousing process and inclusion of a large City of Austin | Environmental Commission Variance Application Guide 4 November 4, 2020Page 410 of 38B-2 b) c) automated storage solution within the warehouse requires a uniform finished floor elevation similarly found in other warehouses. The building type, layout, and ingress/egress features are based upon the materials handling needs of the warehousing, shipping, and receiving processes. This layout is similar to other such facilities in the Austin area and we feel that the variance does not provide special privilege not enjoyed by other similarly situated properties and similarity timed development. Is the minimum deviation from the code requirement necessary to allow a reasonable use of the property; YES / No A retaining wall is proposed parallel to Giles Lane a horizontal distance of approximately fifteen (15) feet from the western edge of the building foundation. This retaining wall is an integral part of the slab on grade building foundation and acts as a vertical moisture retarder. This retaining wall also serves to minimize the extent of the cut to the 15’ immediately adjacent to the building foundation on the west side; the grade at the top of the wall varies and matches existing grades. Although cut areas in the south and north truck court could not be limited due to the standard 4’ dock height required, the truck court grades slope with the natural contours as much as possible while maintaining minimal slopes to facilitate the maneuverability and circulation of the truck traffic. Does not create a significant probability of harmful environmental consequences. YES / No The proposed LSC project does not create a significant probability of harmful environmental consequences. The project will not impact any heritage trees. No floodplain or creek buffers exist within or adjacent to the limits of construction. An old stock pond with a fringe wetland exists within the limits of construction and has been classified at a wetland CEF. This CEF is very low in vigor, density and diversity (according to site visits and review by Horizon Environmental Services, Inc and corroborated by Watershed Protection staff). The project has been designed to incorporate and enhance the existing wetland CEF. The drainage of the site has been designed to increase the contributing drainage area to the wetland. The wetland area will be improved by not only enlarging the permanent pool but also creating several littoral shelves and vegetated benches. The littoral shelves and benches will create a safe haven, breeding place, and healthy habitat for fish and indigenous wildlife such as birds, dragonflies, and frogs around the wetland. Mosquitofish will be introduced to the wetland to control the mosquito population. Water shading plants will provide shade for aquatic life and cool water temperatures. City of Austin | Environmental Commission Variance Application Guide 5 November 4, 2020Page 511 of 38B-2 Mitigation for encroachment within the 150’ wetland setback is required at a ratio of 1:1; 141,800 mitigation points are required. Proposed enhancements to the wetland area exceed the mitigation requirement; 152,817 mitigation points have been provided based on plantings alone. Trees, grasses and shrubs proposed increase the biodiversity of the area and will survive with varying levels of water. Species that produce berries and nuts, and pollenating plants have been selected to provide benefits to the wildlife including birds, and pollinators such as bees and butterflies. The project proposes to add three (3) biofiltration ponds and a partial sedimentation/ filtration pond; all City of Austin water quality regulations have been met. An Integrated Pest Management Plan will be developed for the areas of campus that contribute to the three (3) proposed biofiltration ponds. The proposed LSC project results in a significant reduction in miles traveled by bringing seven (7) off-site facilities to one central on-site location. This 84,000 mile-per-year reduction not only results in less traffic congestion, but also results in substantial air quality benefits due to the reduction in carbon dioxide and greenhouse gas emissions; water quality benefits due to the reduction in hydrocarbons, heavy metals and TSS from fuel, oil and particle laden runoff from roadways; and also, a reduction in noise pollution. 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 Yes, the proposed LSC project will provide equal or better water quality than would have resulted if the development had proceeded without the variance. With the addition of three (3) biofiltration ponds and a partial sedimentation/ filtration pond, all City of Austin water quality regulations have been met. In addition, the project has been designed to incorporate and enhance the existing wetland CEF. The CEF is an old stock pond with a fringe wetland around its bank and a contributing area of approximately 3.2 acres. Drainage of the site has been designed to increase the contributing drainage area to the wetland to 15 acres. Biofiltration ponds have been designed on both the east and west side of the wetland each with two sedimentation basins and a biofiltration basin. The filtration underdrains will be pumped to the wetland. In addition, condensate recovery tanks will also drain to the wetland ensuring a continual source of water to the wetland plants. The wetland CEF provides another layer of water quality to the contributing drainage area by extending biological contact time with sustainable aquatic species and vegetation. The wetland area will be improved by not only enlarging the permanent pool but also creating several littoral shelves and vegetated benches. The littoral shelves and benches will increase the nutrient uptake and also create a safe haven, breeding place, and healthy habitat for fish and City of Austin | Environmental Commission Variance Application Guide 6 November 4, 2020Page 612 of 38B-2indigenous wildlife such as birds, dragonflies, and frogs around the wetland. Mosquitofish will be introduced to the wetland to control the mosquito population. Water shading plants will not only provide shade for aquatic life and cool water temperatures, but will also provide an additional form of filtration by removing nitrogen and phosphates. Mitigation for encroachment within the 150’ wetland setback is required at a ratio of 1:1; 141,800 mitigation points are required. Proposed enhancements to the wetland area exceed the mitigation requirement; 152,817 mitigation points have been provided based on plantings alone. Trees, grasses and shrubs proposed increase the biodiversity of the area and will survive with varying levels of water. Species that produce berries and nuts, and pollenating plants have been selected to provide benefits to the wildlife including birds, and pollinators such as bees and butterflies. As previously mentioned, four (4) water quality ponds are proposed with the LSC project. Two (2) biofiltration ponds will flank the wetland as discussed above, a third biofiltration pond is proposed north of the LSC near Giles Lane and a partial/sedimentation filtration pond is proposed southeast of the LSC near US Hwy 290. Similar to the biofiltration ponds adjacent to the wetlands, the biofiltration pond north of the LSC will have plant diversity and provide ecological benefits beyond the water quality benchmark. An Integrated Pest Management Plan will be developed for the areas of campus that contribute to the three (3) proposed biofiltration ponds. The proposed LSC project results in a significant reduction in miles traveled by bringing seven (7) off-site facilities to one central on-site location. This 84,000 mile-per-year reduction not only results in less traffic congestion, but also results in substantial air quality benefits due to the reduction in carbon dioxide and greenhouse gas emissions; water quality benefits due to the reduction in hydrocarbons, heavy metals and TSS from fuel, oil and particle laden runoff from roadways; and also, a reduction in noise pollution.

The investigation and data analysis demonstrated that the identified wetland area met the requisite criteria (hydrophytic vegetation and hydrology) to be classified as a wetland CEF (W-1). The CEF is mapped in Figure 4, with feature dimensions provided on the City of Austin CEF Worksheet and photographs attached. The field delineation for wetland CEFs was conducted according to the 1987 US Army Corps of Engineers (USACE) Wetlands Delineation Manual. The hydric nature of vegetation species was determined from the 2016 USACE National Wetland Plant List. At the time of Horizon’s site reconnaissance, the wetland CEF exhibited hydrology indicators (ponding, water marks, sediment deposits, and saturation) and hydrophytic vegetation was present. Proposed Buffers The City of Austin generally requires that 150-foot buffer zones be placed on all CEFs. No additional buffers are proposed for the on-site wetland CEF. If development is proposed within the wetland CEF and the CEF setback, the Watershed Protection Department may administratively reduce the standard buffer or approve wetland mitigation. Wetland mitigation occurs at least at a 1:1 ratio for wetland CEFs and their associated 150-foot buffers. All activities within the CEF and associated setback must comply with the City of Austin Land Development Code.
