II. SPECIAL SERVICES A. ENVIRONMENTAL SERVICES CP &Y will conduct wetland delineations, a habitat assessment, and cultural resources investigations consistent with local, state, and federal regulations, as required for the selected project alignment. 1. Wetland Delineation Impacts to jurisdictional wetlands and waters of the U.S. would be permitted under Section 404 of the Clean Water Act by the Fort Worth District of the United States Army Corps of Engineers (USACE). CP &Y will conduct a wetland delineation following the 1987 USACE wetland delineation manual procedures and the Great Plains Regional Supplement to the USACE delineation manual. Once field work has been conducted on the project site, the type of permit required will be determined depending on the area of impacts, if any, to jurisdictional waters and wetlands. If a Pre - Construction Notification to the USACE or Individual Permit is required, it would be conducted under a separate work authorization. 2. Threatened and Endangered Species Habitat Assessment CP &Y will review technical databases, technical literature, and governmental publications and databases prior to conducting field surveys to identify federally threatened, endangered, and candidate plant and animal species in the vicinity of the project area. The habitat assessment includes determining whether suitable habitat exists within and adjacent to the proposed project area, taking representative photographs of the project area, and reporting all findings. Protocols for determining required habitat will be performed for the federally threatened, endangered, and candidate species in Hays County. If habitat for federally listed species is identified, coordination with the U.S. Fish and Wildlife Service would be conducted under a supplemental agreement. Cultural Resources Investigations The proposed project is being sponsored by the City of San Marcos (the City), a political subdivision of the state of Texas; as such the project would fall under the jurisdiction of the Antiquities Code of Texas. In addition, the City may be applying to the US Army Corps of Engineers (USACE) for permitting to construct project facilities under Section 404 of the Clean Water Act; as such, the proposed undertaking may also fall under the jurisdiction of Section 106 of the National Historic Preservation Act (NHPA). As the project represents a publicly sponsored undertaking with the potential to impact potentially significant cultural resources, the City is required to provide for a cultural resource inventory of the APE. Archival Research Prior to initiating fieldwork, Horizon will: Obtain a Texas Antiquities Permit from the Texas Historical Commission (THC). The application for the Texas Antiquities Permit requires the signature of Horizon's Archeological Principal Investigator and an authorized representative of the project sponsor. Perform basic archival research at the THC, the Texas Archeological Research Laboratory (TARL), the General Land Office (GLO), the National Park Service's (NPS) online National Register Information System (NRIS), and /or other relevant archives for information on previous cultural resource investigations conducted in the vicinity of the project's APE and previously recorded cultural resource sites and historic properties in and near the project's APE. 11/26/2013 5 of 8
