Excess Allocation

25,000 Acre-Feet

-4,830 (Allocation to sub-contractors)

-4,897 (drought buffer)

= 15,273 'Excess Allocation'

'Excess Allocation' can be used:

• to ensure achievement of full allocation in years of low delivery from State (<100%).
• for groundwater banking in and out the of County (currently evaluating in-County).
• for turnback pools (sell to the state or other contractors).
• for permanent sale.
• for yearly/multi-year sale.
• after expansion of facilities and/or contract negotiation.

Relations with CCWA

• 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.
