(Pape-Dawson) conducted a Environmental Resource Inventory (ERI) for the ±14.34-acre Parmer MF project site located in Travis County, Texas. The purpose of this report is to identify any critical environmental features (CEFs) that may exist within the project site. Based on Pape-Dawson’s ERI, the proposed project contains two freshwater scrub-shrub wetlands and four freshwater emergent wetlands which would be considered critical environmental features (CEFs). In addition to the wetlands identified, one intermittent stream was mapped within the project site. The conclusions presented in this report represent the professional opinion of Pape-Dawson Engineers and are limited to the conditions observed at the project site at the time and date of the field investigation. If you have questions or require additional information, please do not hesitate to contact me at (210) 375- 9000 at your earliest convenience. Sincerely, Pape-Dawson Engineers, Inc.

The project site is located northwest of the intersection of East Parmer Lane and State Highway 130 in Austin, Texas The purpose of an ERI is to identify any critical environmental features (CEFs) within the project site. CEFs include bluffs, canyon rimrocks, caves, faults/fractures, seeps, sinkholes, springs, and wetlands (LDC 25- Prior to a site investigation, a desktop review was performed utilizing the following resources to evaluate the project site for potential critical environmental features. • COA environmental data; • Railroad Commission of Texas (RRC) oil/gas well data; • Texas Water Development Board (TWDB) water well data; • Texas Commission of Environmental Quality (TCEQ) water well data; • U.S. Geological Survey (USGS) historical and current topographic maps; • Federal Emergency Management Agency (FEMA)’s digital flood insurance rate maps (dFIRM); • U.S. Fish and Wildlife Service (USFWS) National Wetlands Inventory (NWI); • National Resources Conservation Service (NRCS)’ Web Soil Survey; and • USGS geologic and structural feature data; • TCEQ Edwards Aquifer zone data; and • Google Earth Pro readily available historical and readily available current aerial imagery (Exhibit 2). 8-1; LDC 30-5-1). METHODS Desktop Review H:\Projects\512\49\00\ENV\Parmer-MF_ERI\Draft\20210429_51249-00_ERI-Memo_ParmerMF.docx 1 Backup page 42 of 18889 of 2356±14.34-ACRE PARMER MF Environmental Resource Inventory Field Methods A Pape-Dawson environmental scientist familiar with the requirements of an ERI conducted a site investigation on March 30, 2021. Wetlands and other aquatic resources were delineated using the routine method described in the “Corps of Engineers Wetlands Delineation Manual” (Environmental Laboratory 1987) and the “U.S. Army Corps of Engineers (USACE) Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Great Plains Region (Version 2.0)” (Great Plains Regional Supplement Version 2010). The site was evaluated for other potential CEFs with transects similar to the protocols for assessing wetlands and consistent with the guidelines set forth by the City of Austin. RESULTS Desktop Review Elevation at the site ranged from 570 feet above sea level (ASL) on the northern portion of the project site to approximately 540 feet ASL on the southern portion of the project site and had a general southeast sloping gradient. The COA depicts three tributaries within the project site. Two of the tributaries converge near the center of the project site and drain into the main tributary that transects the project site from west to east and drains southeast off the project site. The RRC, TWDB, and TCEQ do not depict any wells within 150 feet of the project site (Exhibit 2) (COA 2021; RRC 2021; TWDB 2021; TCEQ 2021). The project site is depicted on the 2019 USGS Manor, TX 7.5-minute series topographic quadrangle map. The USGS depicts one pond near the center of the project site and one tributary just south of the depicted pond. The tributary transects the project site from west to east and drains southeast off the project site (Exhibit 3) (USGS 2019). Review of FEMA’s dFIRM panels 48453C0480J (effective August 18, 2014) reveal that the southern half of the project site is transected by the 100-year floodplain of Gilleland Creek Tributary 1C. This tributary feature is depicted to drain southeast into Gilleland Creek. Two additional unnamed tributary features are depicted to converge near the center of the project site before draining south into Gilleland Creek Tributary 1C (Exhibit 4) (FEMA 2021).

According to the NRCS Web Soil Survey, four soil units are mapped within the project site Ferris-Heiden complex, 8 to 20 percent slopes, severely eroded (FhF3); Heiden clay, 3 to 5 percent slopes, eroded (HeC2); Heiden clay, 5 to 8 percent (HeD2); and Tinn clay, 0 to 1 percent slopes, frequently flooded (Tw) are all depicted within the project site (Exhibit 6). The soil unit’s characteristics mapped within the project site are summarized in Table 1 (NRCS 2020b). Only Tw is considered a hydric soil by the National Technical Committee for Hydric Soils (NRCS 2020a). Table 1. Soil units within the project site according to the NRCS Web Soil Survey.

This geologic unit is described as areas where the Pecan Gap Chalk is not present because of gradation to marl, similar to that of the Marlbrook and Ozon Formations. The upper 250 feet is comprised of mostly silty, calcareous clay with sandstone beds and concretionary masses near the top, with some interbeds of sandstone near the base. The lower 200 feet of the unit is primarily composed of quartz sand, fine grained, silty locally calcareous concentrations in discontinued beds. The geologic age of the geologic unit is the Late Cretaceous epoch (Barnes 1983).

A historical aerial photograph from 1995 was available and utilized to effectively investigate the site for CEFs. One tributary feature is depicted to transect the southern portion of the project site from west to east. A pond is visible north of the tributary feature. No direct surface water connections exist between the tributary or the pond identified (Exhibit 9) (Google Earth Pro 2021). Field Results area during the time of the site visit. No bluffs, canyon rimrock, caves, faults/fractures, seeps, sinkholes, or springs were found within the study One intermittent stream, two freshwater scrub-shrub wetlands, four freshwater emergent wetlands, and one freshwater excavated pond were identified and mapped within the project site. Characteristics of the environmental features identified are described in Table 2 below. Table 2. Environmental Features Identified Within the Project Site.

A portion of S-01 had pooled near the south-central boundary of the project site. S-01 drains southeast and off the project site. Two freshwater scrub-shrub wetlands (W-02, W-04) were identified within the project site. These freshwater scrub-shrub wetlands were identified within the riparian corridor of the intermittent stream (S-01) identified. Specifically, W-02 was identified on the southwestern portion of the project site, within the OHWM of S-01, on a topographically elevated portion of the stream. W-04 abutted S-01 near the center of the project site. Four freshwater emergent wetlands (W-01, W-03, W-05, W-06) were identified within the project site. These wetlands were identified within the riparian corridor of the intermittent stream (S-01). W-01 is located east and on the edge of the project site. W-05 and W-06 are located where the intermittent steam drains southeast and off the project site. W-03 surrounds the freshwater pond (W-03) and is located near the center of the project site. A freshwater pond (W-03) was identified within the project site. The freshwater pond is located approximately 75 feet north of S-01, near the center of the project site. This pond is separated by a natural berm. No direct channelized surface water connection was observed between the pond and S-01. Site Photographs are included in Appendix A. Wetland Determination Forms are included in Appendix B. DISCUSSION Based on Pape-Dawson’s ERI, seven environmental features were identified within the project site. Of the seven environmental features, Pape-Dawson would not consider the freshwater pond (W-03) to be a CEF. The freshwater pond (OW-01) is excavated and would likely not be considered jurisdictional by the USACE. The earliest available USGS topographic map from 1968 does not depict a pond at the present-day location of the pond. USACE guidance mandates that artificial lakes and ponds are not jurisdictional if they are constructed or excavated in upland or non-jurisdictional waters. Because this pond is separated by a H:\Projects\512\49\00\ENV\Parmer-MF_ERI\Draft\20210429_51249-00_ERI-Memo_ParmerMF.docx 5 Backup page 46 of 18893 of 2356±14.34-ACRE PARMER MF Environmental Resource Inventory natural berm, there is likely no contribution of surface water flow to the pond in a typical year. Additionally, because the pond is artificial in nature and constructed in an upland; the freshwater pond (W-03) identified would likely not be considered jurisdictional. The COA mandates that permitted water quality wet ponds, roadside ditches, and ponds fed by wells or other artificial sources of hydrology are not considered wetlands. Because W-03 would not exist without artificial manipulation, Pape-Dawson would not consider W-03 to be a CEF. The intermittent stream and two freshwater scrub-shrub wetlands were delineated and mapped according to USACE and COA protocols. The COA’s critical water quality zone for the intermittent stream identified was utilized for this report. A 150-foot buffer was added to both freshwater scrub-shrub wetlands identified, in accordance with COA guidance. The intermittent stream (OW-01), two freshwater scrub-wetlands (W-02, W-04), four freshwater emergent wetlands, and associated buffers are depicted in Based on Pape-Dawson’s ERI, the proposed project contains two freshwater scrub-shrub wetlands and four freshwater emergent wetlands which would be considered critical environmental features (CEFs). In addition to the wetlands identified, one intermittent stream was mapped within the project site. The conclusions presented in this report represent the professional opinion of Pape-Dawson Engineers and are limited to the conditions observed at the project site at the time and date of the field investigation.

If potential CEFs were identified in the field, they were carefully examined and recorded, and each potential feature was described, photographed and its location recorded using a handheld Garmin GPS unit. Field reconnaissance was conducted on December 1, 2020. One CEF was identified within the subject area.
