The request is to allow for modification within the City of Austin fully developed floodplain and Critical Water Quality Zone. Per the attached Environmental Commission Variance Application Form Findings of Fact, this variance is required to allow for development on a tract of land at 6700 Decker Lane, located at the northwest intersection Decker Lane and Loyola Lane. There are two locations where an existing engineered drainage channel traverses the site: one at the northern portion of the site and the second crosses further downstream at the southeastern corner of the site. Both of these channels are contained within existing drainage easements. The downstream channel at the southeastern corner of the site has been identified as a CWQZ and City of Austin floodplain due to the additional drainage that is conveyed from across Decker Lane from the east through an existing culvert crossing that has been identified as Elm Creek and is greater than 64 acres. These site characteristics present a challenge, and in order to provide buildable area and an accessible site plan layout for the proposed affordable multifamily development, there are modifications that need to be made to the COA floodplain and CWQZ to allow for fill up to 4ft in depth to better contain the floodplain within the drainage channel and drainage easement. Major effort was made to minimize modifications to the area and the site plan layout had taken the preservation of the southeastern corner into account to be able to preserve the environmental features in the area. For this variance, there is only one (1) primary location where the modifications are proposed which is at the southeastern corner of the site. Due to the floodplain modifications that are being proposed, this site plan will provide floodplain restoration as a result of the Functional Assessment of Floodplain Health that was performed in the area. Based on the existing conditions the existing area was found to be in fair health. This site plan will propose additional floodplain restoration plantings to enhance the existing floodplain area into good health. In addition, mitigation seeding will be proposed in the entire area to enhance the existing wetland that is identified in the drainage channel area. Your favorable consideration of this request is appreciated.

The total site area is about 10.08 acres and existing topography ranges from go from 542 to 561 across the site. There are no natural slopes greater than 15% on the site. There are no heritage trees on the site. There is primarily an assortment of Willow and Ash trees with a few Hackberry and Cottonwood trees within the site. Most of them are located around the existing CEF wetlands on site that will be preserved. There are no heritage trees existing on the site. Two wetland CEFs exist on the site, they are located within the existing engineered drainage channels that run through the site, one at the northern and the other at the southeastern corner. A City of Austin floodplain 25 yr and 100 yr fully developed floodplain the crosses the southern corner of the site due to the offsite contributing area greater than 64 acres immediately on the upstream east side of Decker Lane that is conveyed under Decker Lane in existing box culverts from that is routed through the southeast corner of the site and is routed to existing box culverts under Loyola Lane. A CWQZ is also located along the south corner of the property within the same area. Also, there is a partially excavated detention pond form a previous site plan the did not complete construction that City of Austin | Environmental Commission Variance Application Guide 2 is currently impacting the quality of the CWQZ and CER buffer area. This project is proposing modifications within the floodplain and CWQZ. November 25, 2024 Clearly indicate in what way the proposed project does not comply with current Code (include maps and exhibits) 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: Loyola Flats Ordinance: LDC 25-8-263 Floodplain modification A. 1. 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 Based on the existing topography on the site and the existing engineered drainage channels that traverse the site the floodplain and wetlands that are generated limits the buildable areas. In order to generate buildable areas, it is necessary to modify in the floodplain to add fill in the CWQZ zone and existing floodplain in addition to providing mitigation planting in this area. The fill modifies the floodplain so that it is contained within a closer proximity to the existing engineered drainage channel and is able to be contained within a proposed drainage easement. The proposed fill in the CWQZ area does not exceed 4 feet in depth. City of Austin | Environmental Commission Variance Application Guide 3 November 25, 2024 2. The variance: a) Yes 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; Loyola Flats is a Smart Housing/Affordability Unlocked multifamily residential development generally designed to follow the existing topography to preserve the natural drainage patterns and route offsite flows through the site to the low point on site. In addition, the water quality and detention basins have been placed in natural low areas to preserve the existing drainage patterns. The site has been designed to preserve the natural drainage basin characteristics of the land and will preserve existing wetland CEFs and provide additional mitigation plantings in the CEF buffer and CWQZ to enhance the area as well as paying into the mitigation fund. This variance request is not driven by a design decision on our side and has involved in depth collaboration and guidance by City staff. All design decisions have been with the code requirements of the ECM in mind. Is the minimum deviation from the code requirement necessary to allow a reasonable use of the property; b) Yes Loyola Flats has been designed to minimally deviate from the code to allow for preservation of the CWQZ and floodplain area as well as the existing wetlands. The site layout considered these buffer areas and minimized the improvements within them to only fill of the floodplain to provide a more defined floodplain within the drainage channel for the health and safety of the public and to allow for the development of this site as well as mitigation plantings to enhance the buffer area. c) Does not create a significant probability of harmful environmental consequences. Yes The proposed site layout and associated drainage conveyance system have been designed to minimize the impact and improvements proposed within the Critical Environmental Features, CWQZ and floodplain by ensuring that the contributing drainage basins are preserved, and they receive the necessary surface water runoff quantity and quality needed to promote wetland and floodplain health. In addition, the proposed design provides mitigation plantings that will restore City of Austin | Environmental Commission Variance Application Guide 4 November 25, 2024 the environmental area and enhance to improve the existing condition. Based on the prepared Functional Assessment of Floodplain Health, the existing condition of the floodplain was characterized as fair. The proposed improvements will allow for the floodplain condition to be enhanced from its existing condition. 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 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. In addition, the proposed design preserves the natural drainage patterns by better containing the floodplain along the drainage channel and providing additional planting to enhance the natural features of the area by also restoring the area where the existing detention pond is located the CWQZ to a better condition. 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.

(Terracon) is pleased to submit this City of Austin (COA) Environmental Resource Inventory (ERI) report addressing COA compliance requirements as they may affect the above referenced project site in accordance with Terracon Proposal No. P96237567 dated September 7, 2023 and authorization to proceed dated September 8, 2023. The results of this report are based on the professional opinion of Terracon and site conditions observed during the field reconnaissance. It should be noted that some critical environmental features (CEFs) may be seasonal or ephemeral, indicating that their presence/absence and condition are dependent on various weather conditions (including rainfall) and other changes to the surrounding ecosystem. Terracon is not liable for ephemeral and/or seasonal CEFs that are exposed or created after Terracon’s field assessment. Additionally, Terracon’s opinion is based on current COA regulations; therefore, changes in regulations may require a re-evaluation of the findings of this report. It is recommended this report be promptly submitted to the COA, otherwise an updated report (based on an additional field assessment) may be required to evaluate ephemeral and/or seasonal CEFs. It should be noted that the COA has the ultimate authority for CEF classifications. We appreciate the opportunity to provide this report.

The review of the NWI Mapper indicated the presence of one suspect riverine area (R4SBC) on the southern portion of the site. R4SBC is further described as riverine, intermittent, streambed, and seasonally flooded. The NWI mapper did not reveal other suspect wetlands or waterbodies on the project site or within 150 feet. Additionally, as mapped by the Federal Emergency Management Agency (FEMA) Flood Insurance Rate Map (FIRM) Panel No. 48453C0470K (Effective January 6, 2016), the project site is mapped outside the 100-year and 500-year floodplains and is in Zone X (unshaded). On September 25, 2023, Terracon accessed the COA Property Profile Tool to review previ- ously identified Natural Features and setbacks within and adjoining the site. The review of the COA Property Profile Tool indicated the presence of five Natural Features (COA Creeks) and one buffer (COA Critical Water Quality Zone). This natural feature and buffer are dis- played on Exhibit 6 in Appendix B. For additional (https://www.austintexas.gov/department/gis-and-maps). information please refer to the online COA Property Profile Tool The project site is mapped outside COA 25-year and 100-year Fully Developed Floodplain. Atlas 14 floodplain regulations include amendments to the Land Development Code (LDC) Chapter 25- 7, Section 25-12-3, Title 30, Section 25-7-152, and Section 25-7-61. With these amendments in effect, the floodplain definitions will be revised so that the new 100-year floodplain is synonymous with the current 500-year floodplain and the new 25-year floodplain is synonymous with the current 100-year floodplain. For additional information regarding Atlas 14 please refer to the online resource (http://www.austintexas.gov/atlas14). Field Reconnaissance During the site reconnaissance, Terracon assessed areas for CEF characteristics throughout the project site and identified three CEF wetland areas. Please see Appendix C for site photographs. Coordinate locations for the CEF areas are listed in the above CEF Worksheet and are illustrated on Exhibits 2.0- 2.1 in Appendix B. The CEF areas are further described below: Facilities | Environmental | Geotechnical | Materials 1 City of Austin (COA) Environmental Resource Inventory (ERI) Austin Loyola Tracts | Austin, Texas October 12, 2023 (revised (cid:45)anuary 5, 202(cid:23) | Terracon Report No. 96237567 Wetland W-1 is a fringe wetland located on the southern portion of the site and appears to be associated with a COA Natural Feature (COA Creek), Elm Creek. The limits of W-2 coincide with the previously identified wetland CEF from the COA Property Profile Tool. W-2 is dominated by black willow (Salix nigra – FACW), annual marsh elder (Iva annua – FAC), poison ivy (Toxicodendron radicans – FACU), narrowleaf cattail (Typha angustifolia – OBL), green ash (Fraxinus pennsylvanica – FAC), tall goldenrod (Solidago altissima – FACU), variable flatsedge (Cyperus difformis - OBL), switchgrass (Panicum virgatum – FAC), common spike-rush (Eleocharis palustris – OBL), Chinese tallow (Triadica sebifera – FAC), hackberry (Celtis laevigata – FAC), and prairie false foxglove (Agalinis heterophylla – OBL) within and throughout the edges of the wetland. W-2 displays the hydrology indica- tors from the Great Plains Region USACE Wetland Determination Data Form in the form of Surface Water (A1), Saturation (A3), Drainage Patterns (B10), and Geomorphic Position (D2). Please refer to Exhibit 6 in Appendix B for the location of the COA Creek. Wetland W-2 is a fringe wetland located on the northeast corner of the site and extends offsite to north of the northern site boundary and appears to be associated with a COA Nat- ural Feature (COA Creek). W-3 is dominated mexican primrose willow (Ludwigia octovalvis – OBL), narrowleaf cattail (Typha angustifolia – OBL), giant ragweed (Ambrosia trifida- FAC), prairie false foxglove (Agalinis heterophylla – OBL), Johnson grass (Sorghum halepense – FACU), white mulberry (Morus alba – FACU), sand spikerush (Eleocharis montevidensis – FACW), velvet ash (Fraxinus velutina - FAC), poison ivy (Toxicodendron radicans – FACU), hackberry (Celtis laevigata – FAC), Jerusalem thorn (Parkinsonia aculeata – FAC), and sedge spp. (Cyperus spp. – FACW) throughout the wetland and displays the hydrology indicators from the Great Plains Region USACE Wetland Determination Data Form of algae on the Surface Water (A1), Saturation (A3), and Drainage Patterns (B10). Please re- fer to Exhibit 6 in Appendix B for the location of the COA Creek. Wetland W-3 is a fringe wetland located off-site and within the 150-foot buffer to the south of the southern site boundary on the southwestern portion of the site and appears to be associated with a COA Natural Feature (COA Creek), Elm Creek. W-4 is dominated by black willow (Salix nigra – FACW), narrowleaf cattail (Typha angustifolia – OBL), green ash (Fraxinus pennsylvanica – FAC), Giant trifida – FAC), Jerusalem thorn (Parkinsonia aculeata – FAC), Roosevelt weed (Baccharis neglecta – FAC), mexican primrose willow (Ludwigia octovalvis – OBL), Johnson grass (Sorghum halepense – FACU) and sand spikerush (Eleocharis montevidensis – FACW) throughout the wetland and displays the hydrology indicators from the Great Plains Region USACE Wet- land Determination Data Form in the form of Saturation (A3). Please refer to Exhibit 6 in Appendix B for the location of the COA Creek. Additionally, a roadside ditch with hydrophytic vegetation and flowing water present was observed along the eastern/southeastern boundary of the site during the site reconnaissance. Hydrophytic vegetation included species such as narrowleaf cattail (Typha angustifolia – OBL), prairie false foxglove (Agalinis heterophylla – OBL), annual marsh elder (Iva annua – FAC), swamp smartweed (Persicaria hydropiperoides – OBL), bushy bluestem (Andropogon glomeratus – FACW), black willow (Salix nigra – FACW), mexican primrose willow (Ludwigia ragweed (Ambrosia Facilities | Environmental | Geotechnical | Materials 2 City of Austin (COA) Environmental Resource Inventory (ERI) Austin Loyola Tracts | Austin, Texas October 12, 2023 (revised (cid:45)anuary 5, 202(cid:23) | Terracon Report No. 96237567 octovalvis – OBL), sand spikerush (Eleocharis montevidensis – FACW), common spike- rush (Eleocharis palustris – OBL), Jerusalem thorn (Parkinsonia aculeata – FAC) velvet ash (Fraxinus velutina – FAC), and vasey grass (Paspalum urvillei – FACW). However, according to the COA Environmental Criteria Manual (ECM) 1.10.3(E): “Per(cid:16) mitted water quality wet ponds, roadside ditches, and ponds fed by wells or other artifi- cial sources of hydrology are not considered wetlands” and therefore, is exempt from CEF designation. At the time of the site reconnaissance (September 26, 2023), a privately maintained pond (PMP) was observed on the southern portion of the site and appeared to be regularly mowed and maintained. Based on a review of the COA Property Profile Tool website on January 5, 2024, this area is no longer designated as a PMP by the City of Austin. Description of Site Plant Communities Continued… During the site visit, Terracon assessed areas that represented different vegetative communities throughout the project site to thoroughly review if these areas may exhibit hydrophytic vegetation. Upland vegetative communities were observed to be dominated by species including hackberry (Celtis laevigata), eastern cottonwood (Populus deltoides), flame leaf sumac (Rhus copallinum), honey mesquite (Prosopis glandulosa), eastern redbud (Cercis Canadensis), velvet ash (Fraxinus velutina), giant ragweed (Ambrosia trifida), green milk weed (Asclepias viridis), Illinois bundle flower (Desmanthus illinoensis), maximilian sunflower (Helianthus maximiliani), Dallis grass (Paspalum dilatatum), Johnson grass (Sorghum halepense), frog fruit (Phyla nodiflora), Roosevelt weed (Baccharis neglecta), spreading hedge parsley (Torilis arvensis), switchgrass (Panicum virgatum), Bermuda grass (Cynodon dactylon), poison ivy (Toxicodendron radicans), and mustang grapevine (Vitis mustangensis). Hydrophytic plant species are listed above in the Field Reconnaissance section. The overall vegetated cover associated with the site is an estimated 95 percent. 3 Facilities | Environmental | Geotechnical | Materials  APPENDIX B EXHIBITS Kta566554560542540546554568564538572560560568570540540550572544548544546544544542554554546558548560552576552548552566568536544546546548562564556558556574556554554552562PH.

FLOOD STATEMENT: According to Community Panel No. 48453CO47OK dated 1/6/2016 of the Federal Emergency Management Agency (FEMA) Flood Insurance Rate Map (FIRM), the subject tract is located within Zone “X” (un-shaded) which is defined by FEMA as “areas determined to be outside the 0.2% annual chance floodplain,” commonly known as the 500-year floodplain. Zone “X” (un-shaded) is outside of any FEMA established flood hazard zone. All zone delineations shown hereon are approximate. This flood statement does not imply that the property and/or the structures thereon will be free from flooding or flood damage. On rare occasions, greater floods can and will occur and flood heights may be increased by man-made or natural causes. This flood statement shall not create any liability on the part of Kimley-Horn or the undersigned. 3. GEODETIC BASIS STATEMENT: HORIZONTAL CONTROL: The bearings shown hereon are the Texas State Plane Coordinate System, CENTRAL Central Zone (FIPS 4203) (NAD'83), as determined by the Global Positioning System (GPS). All distances shown hereon are on the SURFACE. To convert Surface distances to Grid apply the Surface to Grid Scale Factor of 0.999900009. The unit of linear measurement is U.S. Survey Feet. VERTICAL CONTROL: This drawing shows existing spot elevations and contour lines based upon a field survey conducted by survey personnel. The contour interval is 1 foot. All elevations shown hereon are tied to the North American Vertical Datum of 1988 (NAVD '88) based on GPS observations. 4. Any underground utilities shown hereon are from Texas 811 markings located by survey crews, or record drawings obtained from utility companies representatives. Kimley-Horn cannot guarantee the locations of said utilities, except those that are observed and readily visible on the surface at the time of this survey. Kimley-Horn assumes no liability for poorly or improperly marked utility locations. Private interior service lines are not shown. 5.

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 plant species and did not classify soil types by laboratory methods. This report is for the exclusive use of the client and any relying government entities for the project being discussed.

(Terracon) is pleased to provide this City of Austin (COA) Functional Assessment of Floodplain Health (FAFH) report prepared for the above- referenced site. Based on the proposed design plans, some modifications would impact the COA Fully Developed Floodplain and/or the COA Critical Water Quality Zone (CWQZ). Terracon established one Zone 1 transect and one Zone 2 transect within the COA Fully Developed Floodplain area and/or Critical Water Quality Zone (CWQZ) on the northern portion of the site. To accommodate the length of the area proposed for design impact within floodplain of the project area, transect 1 (T-1) is approximately 100-meters with three 100-square meter sample plots (P1, P2, and P3). Transect 2 (T-2) is an approxi- mately 45-meter transect with one 100-square meter sample plot (P1). The Zone 1 transect was scored for vegetative buffer gap frequency, large woody debris, soil compaction, struc- tural diversity, and tree demography. The Zone 2 transect was scored for vegetative buffer gap frequency, large woody debris, soil compaction, structural diversity, tree demography, wet- land tree status, and riparian zone width.

Also at- tached are the FAFH Score Sheets and Photolog for reference. The results of our consulting services are solely the professional opinion of Terracon and are basedon the site conditions documented and observed at the time of the field investigation. It should be noted that some site conditions are subject to various weather conditions (including precipitation) and other changes in the surrounding ecosystem. This report is intended to describe on-site conditions at the time of the investigation and Terracon is not liable for seasonal changes in on-site vegetation or hydrology. Additionally, Terracon’s opinion is based on the most current regulations; therefore, changes in regulations may require a re-evaluation of the findings of this report. It is recommended that if this report is not to be submitted promptly to the COA, an updated report (based on an additional field assessment) be prepared.

Specific objectives for the candidate species were to assess distribution, relative abundance, population demographics, and habitat associations. Mr. Jenkerson was responsible for surveying, species identification, and quantifying functional habitat parameters. This extensive effort provided Mr. Jenkerson hands on experience with the survey, handling, and identification of thousands of endemic Texas mussel species. Mr. Jenkerson also assisted with several applied research projects related to this work, including the execution of mark-recapture studies to gain insight into population dynamics and movement of mussel assemblages in the Colorado River. Freshwater Fish and Mussel Inventories (2017 – Present). Multiple clients. Jenkerson leads and assists with species inventory efforts in aquatic systems across multiple states. This work typically involves the application of various freshwater mussel (qualitative and quantitative tactile and visual surveys) and fish sampling techniques (boat, barge, and backpack electro-fishing, gill-netting, and kick-netting) and species identification to provide an assessment of assemblage structure for the development of appropriate habitat management plans. His responsibilities include development and implementation of field protocol, client and agency communication, and reporting. Multiple clients with examples including Tetra Tech (2018 – 2019) and ALL consulting (2018), and the Department of Defense (2019).  Gonzales Hydroelectric Dam FERC Relicensing Project (2016 – 2018). Schneider Engineering. Mr. Jenkerson inventoried fish, wildlife, and botanical resources in and around a hydroelectric dam site in Gonzales, Texas. Mr. Jenkerson was responsible for data collection and analysis, including an assessment of impingement, entrainment, and American eel passage. His responsibilities included the application of electrofishing, gill nets, eel pots, and eel ramp traps. Mr. Jenkerson also conducted all reporting related to desktop analysis assessing the potential impacts of dam operations on local fish assemblages. PUBLICATIONS/PRESENTATIONS Jenkerson, J.T. 2022.
