ARCHAEOLOGY PROJECTS

4S Ranch Project, San Diego County
Located west of Rancho Bernardo, the 4S Ranch Project is one of the largest land development ventures in San Diego County.
BFSA began work on the 4S Ranch Project in 1980, which included an intensive archaeological survey of the 3,600-acre property that resulted in the identification of 170 archaeological sites. Since 1980, eight additional studies have been conducted on the 4S Ranch Project, including a testing program to determine the significance of the 170 archaeological sites and assess the potential impacts of the proposed development of the property.
The final survey and testing report for the 4S Ranch Project is a 10-volume, 5,000-page document that became a technical appendix for the 4S Ranch Environmental Impact Report, which was accepted by the County of San Diego in 1998. As part of the 4S Ranch archaeological program, a master Cultural Resource Management Plan was developed in concert with the County of San Diego and in compliance with CEQA. The Cultural Resource Management Plan was designed for the management of all cultural resources within the property and, as a result, over 80 sites of various levels of importance were preserved in open space.
For the significant sites within the development envelope, a master research design was prepared to outline the relevant research objectives of future excavations, the range of special studies needed to complete the research, and the size of excavations for data recovery programs to achieve the mitigation of impacts. The data recovery program completed in 2011 represents one of the largest data recovery programs ever undertaken in San Diego County and has resulted in major advances in our understanding of prehistoric cultures in this area.

San Diego Padres PETCO Park, Downtown San Diego
BFSA was retained by the San Diego Padres under the City of San Diego to implement the mitigation monitoring program for the new downtown ballpark. During this program, hundreds of historic features and deposits were discovered and studied. The analysis of artifacts from historic features identified several different periods of use and ethnicities between 1880 and 1940.
The historic artifact collection from the PETCO Park Project represents one of the largest collections of historic artifacts in the city of San Diego. Examples of these artifacts can be seen in an interpretive display assembled by BFSA in the Western Metal Supply Co. building inside the park itself.

Verlago Project, City of Peoria, Arizona
BFSA conducted an archaeological survey of the proposed 1,436-acre Verlago Project located in the Peoria Lakes area of Arizona, west of Lake Pleasant Parkway and east of the Agua Fria River. The property is being considered for residential and resort development. The project covers the mesas and terraces along the Agua Fria River where numerous prehistoric sites were recorded, including the Calderwood Ruins. The archaeological study included records searches at the Arizona State Museum and a physical survey of the property. A total of 32 archaeological sites were identified and subjected to an initial assessment of significance, including major prehistoric occupation sites with habitation structures, temporary camps, lithic scatters, rock walls, canal sections, and water collection channels.

Interstate 15 Widening Project, Rainbow Valley to Riverside County
The Interstate 15 Widening Project was completed for Caltrans and involved an archaeological survey and extended Initial Study for cultural resources within the Interstate 15 right-of-way alignments in northern San Diego County and a portion of Riverside County. Following the survey, the identified resources were subjected to testing for significance evaluations. The cultural resource study was conducted in compliance with CEQA and Section 106 of the NHPA.

Los Angeles Department of Transportation (LADOT) Bus Maintenance and CNG Fueling Facility Project, County of Los Angeles
BFSA provided mitigation monitoring expertise to the LADOT during the grading and construction of the new downtown bus maintenance yard. BFSA monitored excavations that covered three city blocks and encountered multiple historic features and artifact deposits. Off-site construction utility trenches also encountered human remains representing the prehistoric Gabrieleño occupation of the area.
The archaeological study focused, in part, upon the relocation and assessment of historic waterway, the Zanja Channel, which is mapped as crossing the property. Significant discoveries during the mitigation program added important information to the history and prehistory of the county of Los Angeles.
