Exhibit 2.3: Time and Effort Required for Cultural Resources Compliance

Exhibit 2.3 PDF version here.

The time and effort required to complete cultural resources compliance will vary greatly, depending on the nature of the project and the number and types of resources that may be impacted by it.

The Table below indicates potential requirements in person-hours for the major activities, based primarily on Caltrans' Workload Estimating Norms. Also included are estimates of standard person-hour requirements and elapsed schedule time for some activities, based on Caltrans' Environmental Handbook. In estimating schedule time, it should be noted that some activities could be done at the same time.
