environmental concerns: Conduct a sitewalk of each of the 109 properties; interview propertyowners and/or facility operators; and obtain and review historical aerial photographs, SanbornInsurance Maps, and Municipal records in accordance with ASTM Standard E 1527-00.Completing these remaining ASTM Standard components is integral to identifying and analyzing“environmental issues” and providing more definitive conclusions and recommendationsregarding the individual properties.2618s10ES-2
1.0 INTRODUCTION1.1 Objective and Scope of WorkThe objective of this study was to conduct a Limited Phase I Environmental Site Assessment(ESA) for two areas within the San Antonio River General Re-evaluation Study project. TheFort Worth District, U. S. Army Corps of Engineers (FWCOE) and the San Antonio RiverAuthority (SARA) identified two project areas along the San Antonio River. The purpose of thisLimited Phase I ESA was to initially determine the potential environmental impacts on the twoproject areas, the Park Reach located north of the downtown areas and the Mission Reach locatedsouth of the downtown area, through review of available documentation, site reconnaissance, andidentification of any recognized environmental conditions. See Figure 1.1-1, General LocationMap, for the approximate boundary locations of the Park Reach and Mission Reach. MissionReach has been divided into two sections, Mission Reach Area I and Mission Reach Area II, forconvenience in describing the areas.To fulfill these requirements, this Limited Phase I ESA was performed in accordance withspecific components contained in the American Society for Testing and Materials (ASTM)Standard E 1527-00, Standard Practice for Environmental Site Assessments, Phase IEnvironmental Site Assessment Process. These components were selected by the FWCOE withinput from the SARA.This Limited Phase I ESA Report has been prepared by Tetra Tech NUS, Inc. (TtNUS) for theFWCOE under Contract No. DACA63-97-D-0030, Delivery Order No. 0034. Furthermore, thisstudy was conducted in accordance with FWCOE’s Detailed Statement of Work (SOW), datedMay 10, 2002.1.2 Approach and Report ContentsA total of 109 individual properties included in the Park Reach and the two areas of the MissionReach were identified by the SARA for assessment. See Figures 1.2-1, 1.2-2 and 1.2-3,Topographic Site Location Maps, for a topographic presentation of the approximate locations ofthe Park Reach and Mission Reach Areas I and II, respectively.In accordance with the SOW, the general vicinity of the San Antonio River along the Park Reachand the Mission Reach Areas I and II was inspected by TtNUS personnel during a “drive-bysurvey” for the potential presence of environmental impacts. This Phase I ESA was limited tofenceline observation of the property activities and/or suspected presence of environmentalimpacts. Furthermore, in accordance with the SOW, site walk-overs of each individual propertywere not conducted nor were interviews of property/facility owners or the local fire,environmental health, electric and/or water departments undertaken at this time. A review ofhistorical land use was limited to a title search of landownership of the 109 individual properties.A historical study of the land use of the project sites, including review of historical aerialphotographs, was not undertaken at this time. Records review results are presented in the reportby analyzing the information provided by Federal, State and local Agencies, regional geology2618s11-1
