Intensive Cultural Resources Survey of the Proposed City of Conroe Stewarts Creek Wastewater System Improvements Project, Conroe, Montgomery County, Texas

Horizon Environmental Services, Inc. (Horizon) was selected by LJA Engineering, Inc. (LJA), on behalf of the City of Conroe, to conduct a cultural resources inventory and assessment for the proposed Stewarts Creek Wastewater System Improvements Project in Conroe, Montgomery County, Texas. The proposed undertaking would consist of rehabilitating and replacing approximately 2.1 kilometers (1.3 miles) of existing gravity sewer pipeline that runs along the western terraces of Stewarts Creek in the southeastern portion of Conroe. The segment of the existing sewer line proposed for rehabilitation and replacement runs along the western terraces of Stewarts Creek extending from Avenue M southward to an existing transmission line right-of-way (ROW) located southeast of the intersection of Foster Drive and Ed Kharbat Drive. For purposes of the cultural resources survey, the project area was considered to consist of a linear project corridor measuring 2.1 kilometers (1.3 miles) in length by 39.6 meters (130.0 feet) in width, covering a total area of 8.3 hectares (20.4 acres). The proposed undertaking would be sponsored by the City of Conroe, which represents a political subdivision of the state of Texas. As such, the project falls under the jurisdiction of the Antiquities Code of Texas. In addition, the project may require the use of Nationwide Permits (NWP) issued by the US Army Corps of Engineers (USACE), Galveston District, for construction within or adjacent to any water features that meet the criteria for designation as “waters of the US” under Section 404 of the Clean Water Act and/or Section 10 of the Rivers and Harbors Act. As NWPs are federal permits, those portions of the overall project area located within the federal permit area would fall under the jurisdiction of Section 106 of the National Historic Preservation Act (NHPA) of 1966, as amended. As the proposed project represents a publicly sponsored undertaking, the project sponsor is required to provide the applicable federal agencies and the Texas Historical Commission (THC), which serves as the State Historic Preservation Office (SHPO) for the state of Texas, with an opportunity to review and comment on the project’s potential to adversely affect historic properties listed on or considered eligible for listing on the National Register of Historic Places (NRHP) and/or for designation as State Antiquities Landmarks (SAL). On April 1 to 2, 2020, Horizon archeologists Colene Knaub and Elizabeth Sefton, under the overall direction of Jeffrey D. Owens, Principal Investigator, performed an intensive cultural resources
