(c) If, at the time of submittal or resubmittal, the local agency or designee determines it is unable to meet the time limits of this section, the local agency or designee shall, upon request of the subdivider and for purposes of meeting the time limits, contract or employ a private entity or persons on a temporary basis to perform services necessary to permit the agency or designee to meet the time limits. However, a local agency or designee need not enter into a contract or employ those persons if it determines either of the following:

1. (1) No entities or persons are available or qualified to perform the services.

2. (2) The local agency or designee would be able to perform services in a more rapid fashion by modifying its own work schedule than would any available and qualified persons or entities.

   A local agency may charge the subdivider fees in an amount necessary to defray costs directly attributable to employing or contracting with entities or persons performing services pursuant to this section.
