Archaeological Monitoring and Limited Survey Investigations at 41HY261 and 41HY141 for the Cheatham Street Waterline Improvements Project, San Marcos, Hays County, Texas, for Texas Antiquities Permit No. 8332

During the months of April, May, September, and October, the Center for Archaeological Studies (CAS) at Texas State University conducted archaeological monitoring of mechanical excavations for the Cheatham Street Waterline Improvements Project (CSWIP). These excavations were located within archaeological sites 41HY261 and 41HY141, on opposite banks of the San Marcos River. Working under Texas Antiquities Permit 8332, CAS conducted archaeological monitoring and limited survey-level investigations on behalf of the City of San Marcos (the City) to assist them with their regulatory compliance obligations. The total estimated volume of sediment excavated for this project is 718.54 m3. Cultural deposits were encountered within these excavated sediments in association with both 41HY141 and 41HY261. Due to the limited exposure of intact sediments associated with sites 41HY261 and 41HY141, CAS recommends that no further archaeological investigations are necessary for the CSWIP. However, it is recommended that the City continue to coordinate any developments planned within or in the vicinity of the sites with the Texas Historical Commission (THC) prior to undertaking development. Additionally, future Areas of Potential Effect(s) (APE) should be carefully evaluated to determine whether they have a high probability to contain intact archaeological deposits
