Mr. Lorenzo Wingate City of La Porte August 31, 2021 Page 8 Task 9B: Cultural Resources Survey and Reporting Because the project is being developed by City of La Porte, a political sub-entity of the State of Texas, it falls under purview of the Antiquities Code of Texas (Title 9, Chapter 191 of the Texas Natural Resources Code), which requires the Texas Historical Commission (THC) to review actions that have the potential to impact archeological historic properties within the public domain. In order to enable the City to meet Antiquities Code of Texas requirements, Halff will conduct an intensive archeological survey within the project corridor. The work will include the following tasks: Antiquities Permit o Background research will be performed to determine whether any archeological historic properties listed on or eligible for the National Register of Historic Places (NRHP) or designation as a State Antiquities Landmark (SAL) are documented within or adjacent to the project area and if any previous archeological surveys have been performed in the area. Background research will also include a review of local soil, geologic and land use data to evaluate the potential for buried and undisturbed archeological historic properties in the project area. An Antiquities Permit application will be prepared and submitted to the THC for review along with a Research Design that summarizes the background research and description of the field survey methods. Field Survey o Upon receipt of the Antiquities Permit number assigned to the project by the THC, an intensive archeological survey will be conducted within the proposed project area. The field survey will conform to the THC-approved Archeological Survey Standards for Texas and conducted in portions of the project area that have not been previously surveyed. Shovel tests will be hand-excavated on a judgmental basis and conducted where the project area exhibits potential to contain undisturbed archeological deposits. Reporting o Halff will prepare and submit a draft report that conforms to the Secretary of the Interior's Guidelines for Archaeology and Historic Preservation. The survey report will summarize the findings of the archeological survey and provide recommendations regarding any additional archeological work, if needed, with appropriate justifications. Following a period of City review and comment, the draft report will be submitted to THC for review. After addressing any agency comments, Halff will submit a final report to the City and THC. Curation o Pursuant to 13 TAC 26.17, and after acceptance of the final report by the THC, all field records, photographs, and collected artifacts will be prepared for permanent curation at the Center for Archaeological Studies located at Texas State University in San Marcos, Texas. Task 9C: Phase II Environmental Site Assessement Halff will conduct Limited Phase II Site Investigation activities for the above referenced property. The purpose of the assessment is to determine the presence or absence of volatile organic compounds (VOCs) which includes the benzene, toluene, ethylbenzene, and xylene (BTEX) compounds, total petroleum hydrocarbon (TPH), and/or polynuclear aromatic hydrocarbons (PAHs) impacted soil and/or groundwater at the Site which may have resulted from unknown and/or undocumented releases. The proposed investigation will include the installation of three soil
