Excess Allocation

25,000 Acre-Feet
-4,830 (subcontractors)
-5,707 (drought buffer)
= 14,463 'Excess Allocation'

'Excess Allocation' can be used:

  • to ensure achievement of full allocation in years of low delivery from State (<100%).
  • by utilizing an available storage program to save it for drought years.
  • for turnback pools (sell to the state or other contractors).
  • for permanent sale.
  • for yearly/multi-year sales under State initiated programs (e.g. during drought emergencies).
  • after expansion of facilities and/or contract negotiation

Relations with the Central Coast Water Authority

  • Exploring options to maximize use of facilities and allocations.
  • Protecting the contractual rights of existing sub-contractor pipeline capacity is critical while exploring options for future use.
  • Any new sub-contractor would need to 'Buy In' through negotiations - in addition to addressing other operational issues.
