Lake Tugalo Water Treatment Plant at Black Branch

In April 1999 TRC Garrow Associates, Inc. (TRC), completed a Phase I cultural resources survey consisting of both archaeological and architectural assessments of a proposed plant site, pond site, and a pipeline corridor. The archaeological survey recorded three new sites (9HM 199, 9HM200, and 9HM201) and provided further documentation of the previously known Tugaloo Village Site (9HM48), which has already been recommended eligible for the National Register of Historic Places (NRHP). No further work is recommended at sites 9HM199, 9HM200, or 9HM201, and they are considered ineligible for listing on the NRHP. Potentially significant archaeological remains associated with Tugaloo Village (9HM48) are present within the proposed pond site survey area and possibly the pipeline corridor, and these remains are recommended for Phase II testing if current development plans are implemented. Vehicular and pedestrian coverage of the project's Area of Potential Effects (APE) was undertaken to locate historic architectural resources. The architectural APE was defined as the area in which the proposed project would physically or visually affect any historic resources. The historic architecture survey identified seven resources in the project's APE. It appears that no further work is required for the two ineligible resources. In accordance with the criteria of effect and adverse effect in 36 CFR 800.9, it appears that the proposed project will create no adverse effect on HM-145. Additionally, it appears that the project will create no effect on HM-592, HM-593, HS-1, and HS-2 if a buffer of vegetative screening is retained along the boundary of the northern half of the proposed pond site. If a buffer is not retained, it appears that the proposed project will have an adverse visual effect on all four resources. Recommended mitigation measures for the four resources would entail the planting of a new buffer of vegetation for screening, or possibly Historic American Buildings Survey or Historic American Engineering Record recordation.
