FUNCTIONAL ASSESSMENTOF FLOODPLAIN HEALTH23 September 2021 Joe Farias Garza EMC 9442 Capital of Texas Highway North Austin, Texas 78759 RE: City of Austin Functional Assessment, Zone 2 — RBI at Loyola Lane Loyola Lane and Sendero Hills Parkway, Austin, Travis County, Texas HJN 21265.001 FA Dear Mr. Farias: The following provides a functional assessment of floodplain health findings from Horizon Environmental Services, Inc.’s (Horizon) field investigation conducted on 14 September 2021 for the above-referenced subject site. Horizon evaluated the subject site in accordance with the Watershed Protection Ordinance: Functional Assessment (FA) developed by the City of Austin (COA) Watershed Protection Development. The proposed project consists of development that has the potential to modify the 100-year floodplain and Critical Water Quality Zone (CWQZ) adjacent to unnamed tributaries of Walnut Creek. The subject site is located near the intersection of Loyola Lane and Sendero Hills Parkway, Austin, Travis County, Texas (Figure 1). Based on the location of the proposed construction activities within the CWQZ, Zone 2 of the FA was performed. Per the FA guidance, three 100-square-meter sample plots were to be evaluated along eight Zone 2 transects (Figure 2). Horizon took several photographs and measurements using the required tools listed in the FA. The tools included a 100-meter measuring tape, a densiometer, and a soil compaction meter. The hydric nature of vegetation species was determined from the US Army Corps of Engineers (USACE) National Wetland Plant List. Photographs from the FA are provided in Appendix A and scoring sheets for the eight transects are provided in Appendix B. 21265-001FA CORPORATE HEADQUARTERS 1507 S Interstate 35  Austin, TX 78741-2502  (512) 328-2430  www.horizon-esi.com An LJA Company Williamson Taylor, TX Lago Vista, TX §¨¦35 £¤183 Austin, TX Lee Manor, TX Elgin, TX Travis £¤290 Belterra, TX Hays §¨¦35 Subject Site £¤183 Elroy, TX Caldwell Bastrop Bastrop, TX " "" " " " " " " " " " """" Legend " " Transect Subject Site Date: Drawn: 09/15/2021 TED HJN NO: 21265.001FA Source: OSM, 2021 Figure 1 Vicinity Map RBI at Loyola Lane Loyola Lane and Sendero Hills Parkway Austin, Travis County, Texas I 0 1,000 2,000 Feet 21265 - RBI at Loyola Lane\Graphics\21265-001FA_01A_Vicinity.mxd " T-1 " T-7 " " " " T-6 " " " T-2 T-3 " " Parkway Hills Sendero Loyola Lane Cordoba Drive T-4 T-5 " " " " " T-8 Legend " " Transect Critical Water Quality Zone Subject Site Date: Drawn: 09/15/2021 TED HJN NO: 21265.001FA Source: COA, 2016; Nearmap, 2021 Figure 2 Functional Assessment RBI at Loyola Lane Loyola Lane and Sendero Hills Parkway Austin, Travis County, Texas 0 I 200 Feet 400 21265 - RBI at Loyola Lane\Graphics\21265-001FA_01A_Vicinity.mxd Joe Farias HJN 21265.001 FA 23 September 2021 Page 4 BASELINE CONDITIONS The floodplain and CWQZ within the subject site consisted of woodland and grassland vegetation. Vegetation included Ashe juniper (Juniperus ashei), sugarberry (Celtis laevigata), Chinese privet (Ligustrum sinense), cedar elm (Ulmus crassifolia), honey mesquite (Prosopis glandulosa), winged elm (Ulmus alata), black willow (Salix nigra), Texas persimmon (Diospyros texana), false willow (Baccharis neglecta), Texas prickly pear (Opuntia engelmannii), giant ragweed (Ambrosia trifida), silver bluestem (Bothriochloa saccharoides), tall goldenrod (Solidago altissima), spreading hedge-parsley (Torilis arvensis), common broomweed (Amphiachyris dracunculoides), marsh elder (Iva annua), purple morning glory (Ipomoea capillacea), greenbrier (Smilax bona- nox), and other upland forbs and grasses. SUMMARY The results of the Zone 2 - CWQZ FA indicated that the CWQZ within the subject site was in “Fair” condition with an average score of 16.5.
