Locate and/or marking operations involve detecting and/or marking a presence or an absence of at least one underground facility within a dig area, wherein at least a portion of the dig area is planned to be excavated or disturbed during excavation activities. One or more attributes of a locate and/or marking operation requested in a locate request ticket are assessed to provide one or more ticket assessment outcomes. Ticket information is obtained from the locate request ticket, and historical information (e.g., historical damage reports, historical records of previously completed locate request tickets) is selected and analyzed based on the ticket information so as to assign at least one risk designation to the ticket. The risk designation(s) is/are transmitted and/or stored so as to facilitate clearing the locate request ticket and/or dispatching a locate technician to perform the locate and/or marking operation.
