In August 1994, the Center for Archaeological Research entered into a contract with the San Antonio Parks and Recreation Department to provide monitoring for the Trevino Street improvements immediately to the north of San Fernando Cathedral in downtown San Antonio. Previous investigations had shown that the stone-lined San Pedro acequia existed at the curb line on Main Avenue.
Monitoring was conducted as the street surface was removed and, as expected, the acequia was exposed. The location of the acequia was documented by photography and measured drawings. A plan map of the location was produced and archival research revealed the history of the channel at this location.
