Cultural Resource Assessments

An assessment, typically referred to as an "archaeological"or "cultural resources" survey, entails the investigation of a piece of property for the purpose of identifying and assessing the significance of any archaeological or historical resource that may be present. With this information, measures for testing or mitigation are developed to help avoid or lessen potential impacts to the resource. If no resources are present, certification to that extent is given.

Cultural resource assessments involve performing a records search (through the applicable office of the California Historic Resources Information System), a systematic walk-over survey of the property, archival research, and the preparation of a report. This report is specifically designed to comply with the environmental regulations of the government agency that is reviewing the project.

Testing and Mitigation Programs

Cultural resource assessment studies usually end with the survey phase. However, sometimes resources are located that require further investigation in order to compile an adequate data base to allow for a proper evaluation of the site's significance (testing) or to acquire an adequate sample from the site prior to impact by a project (mitigation or "data recovery").

Our testing strategies are generally based upon probability sampling. This ensures statistically viable data and a legitimate evaluation of the significance (or insignificance) of a site. Testing usually involves the excavation of a small number of "units" (one-by-one, one-by-two, or two-by-two meters square). In some instances other studies can substitute for, or supplement, test excavation (e.g. auger holes, shovel test pits, backhoe trenching, surface collection of artifacts).

Testing often indicates that demonstrably significant resources are not present and mitigation of impacts is not necessary. However, when a significant deposit is located mitigation measures may be necessary. We have substantial experience in all aspects of mitigation work and can conduct programs in an efficient, cost-effective manner.

Grading Monitoring

Government agencies frequently require the presence of an archaeological monitor on site during rough grading activities for projects. We have experienced, safety-conscience monitors to ensure that significant archaeological and historical resources are not inadvertently impacted during construction. There is a common misconception that if something is found during grading the whole project can be shut down indefinitely with resultant serious financial implications. We strongly believe that if your preliminary studies are conducted correctly all potentially significant deposits will have been dealt with prior to grading. Resources found during grading should therefore be small and capable of easy evaluation and treatment. Usually when a discovery is made, grading work can continue and the find can be dealt with in a matter of hours and with no significant extra cost.
