Climate Change Effects - CaliforniaClimate Change Effects - California

What we are unsure of:

• Magnitude of change

• Temporal variability

• Spatial variability

Page 24: 2007 California Water Developments

Water Resource ImplicationsWater Resource Implications• Source area hydrology will likely change

(snowpack, rainfall, runoff, ET, GW recharge)• Water availability – total, spatial, seasonal• Increased water transfers/wheeling• New supplies• Supply capture balanced with flood control• Delta – will remain an important conveyance and

ecosystem component • Demands will continue to grow

Page 25: 2007 California Water Developments

What does this mean for LAFCo?What does this mean for LAFCo?

• Should acknowledge that: Should acknowledge that: – Water Supplies being Firmed Up– New Supplies being Explored– Difference between “paper” and “wet”

water– Transfers occurring between Agencies– Delivery Constraints– North-South “equation”

Page 26: 2007 California Water Developments

LAFCo MandatesLAFCo Mandates• LAFCo required to review timely availability LAFCo required to review timely availability

of adequate water supplies for any of adequate water supplies for any organization changeorganization change– Gov’t Code §56668k Water Code §65352.5Gov’t Code §56668k Water Code §65352.5

• LAFCo reviews extension of services outside LAFCo reviews extension of services outside of boundariesof boundaries– Gov’t Code §56133 (in vs. out of sphere) Gov’t Code §56133 (in vs. out of sphere)

– LAFCo reviews services to previously unserved LAFCo reviews services to previously unserved territory within unincorporated areasterritory within unincorporated areas

– Gov’t Code §56434Gov’t Code §56434

Water Supply AvailabilityWater Supply Availability• Surface Water• Groundwater• Recycled Water• Demand Reduction• Desalination

Page 28: 2007 California Water Developments

How real is the water supply?How real is the water supply?• “Safe Yield”

– Entitlement restrictions (contract, water right, third party agreement)

– Has it been “perfected”? Long-term or temporary– Shortage provisions– Constrained by storage capability– Constrained by reservoir operational rules– Shared beneficial uses (hydropower, recreation, etc.)– Seasonal use restrictions– Would it offset or delay other customers already

within the service area?

Page 29: 2007 California Water Developments

ExampleExample• Federal Water

“Shortage Policy”– 100,000 AFA M&I

Contract– Ave. Historical Use –

50,000 AFA– Maximum current

cutback – to 37,500 AFA (Dry Year)

– Maximum ultimate cutback – to 75,000 AFA

Page 30: 2007 California Water Developments

ExampleExample• Water Rights –

Terms and Conditions– Minimum bypass

flow requirement– Water right – 100 cfs– Fish bypass flows –

25 cfs (May-June)– Fish bypass flows –

35 cfs (May-June) in Dry Years

Page 31: 2007 California Water Developments

ExampleExample• Water Rights -

Recreational Flows– Water right of 500 cfs– Recreational flows –

no diversions upstream of Point (May-September)

– Requirement for increased releases during specific periods

Page 32: 2007 California Water Developments

ExampleExample• Water Rights – Need for

Implementation Approval

– 50,000 AFA water right

– Federal facilities required to take water

– Have yet to secure a federal Warren Act contract (wheeling agreement)

Page 33: 2007 California Water Developments

ExampleExample• Third Party

Agreements– e.g., Sacramento

Water Forum– 62,000 AFA total

entitlement– 54,900 AFA wet-year

diversion – 39,000 AFA voluntary

cutback in dry-years

Page 34: 2007 California Water Developments

ExampleExample• New Infrastructure

Improvement– Folsom Dam and

Reservoir – Joint Federal Project– FDS/FDR– New Flood

Encroachment Curve– Effects on long-term

carryover for Folsom water supply

Page 35: 2007 California Water Developments

ExampleExample• Changing Rules for

CVP/SWP and Delta Operations– Long-term prescriptions?– Exports– In-Delta standards– COA – Term 91 (balanced

conditions)– Accommodations for

flood control– Climate change effects

Page 36: 2007 California Water Developments

Can the supply be accessed?Can the supply be accessed?

• Is it in a readily accessible reservoir?• Are diversion/conveyance improvements

necessary?• Does adequate treatment capacity exist?• What is the status of the purveyor’s

distribution infrastructure?• Are there water quality concerns?

Page 37: 2007 California Water Developments

Other Issues?Other Issues?• Cross-county

coordination?• “First-come/First

Served” edict still appropriate?

• Prior rights?• By approving a certain

annexation; are we acceding to a water supply alternative with greater environmental effects?

Page 38: 2007 California Water Developments

What form of assurance is What form of assurance is appropriate?appropriate?

• Verbal commitment• “Will serve” letter• Development Agreement• Others?

Page 39: 2007 California Water Developments

Options for Water Supply and Options for Water Supply and Infrastructure VerificationInfrastructure Verification

• Accept as is…• Request explanation

and discussion• Defer to published

information• Perform internal

assessment• Seek third party

review

Page 40: 2007 California Water Developments

Are determinations perpetual?Are determinations perpetual?

• Are LAFCo determinations unchangeable?• What happens if:

– Water supply availability was over-estimated?– Water delivery proves unreliable?– Changes in federal/State regulations?– Current project shown to adversely affect

historic customers (e.g., WQ, reduced reliability)?

– Financing for required CIPs are delayed?

Page 41: 2007 California Water Developments

Can LAFCos Condition Can LAFCos Condition Approvals?Approvals?

• Could a LAFCo:– Require periodic monitoring and reporting?– Review established milestones – to re-verify facts?– Include Re-Opener clauses in agreements?– Amend certain Terms and Conditions of

Determinations?– Seek mitigative remedies?– Thereby: adopt Adaptive Management principles in

the discharge of duties under CKH?

Page 42: 2007 California Water Developments

Liability ConcernsLiability Concerns

• Who bears the burden of liability if:– Water supply information inadvertently

omitted important data?– New information proves a previous LAFCo

determination inaccurate?– It is shown that an approved delivery (through

annexation) could trigger adverse effects under federal law (e.g., Endangered Species Act)

Page 43: 2007 California Water Developments

Liability Concerns (cont.)Liability Concerns (cont.)– It is shown that an approved delivery (through

annexation) could trigger adverse effects to other existing residents?

– Project timing is delayed because certain approvals have not been secured by the water purveyor?

– Conveyance failure occurs?– Development project has to de-mobilize?
