During 1987-1988, archaeologists from the Center for Archaeological Research monitored the excavation of trenches for new sewer pipelines within the Mission Parkway Historic/Archeological District in south San Antonio. In locations where the trenches crossed the mission acequias, boring was conducted to carry the line beneath the channel. At the site of an auxiliary building on the Hot Wells Hotel property, the cutting of a trench was monitored, and foundation wall lines were documented by photography and measured drawings.
