The Water Resources Plan Goals

Technical Analyses

Institutional Activities

PublicInvolvement

• Provide long-term protection to OID’s water rights.

• Address federal, state, and local water challenges.

• Rebuild/modernize an out-of-date system to meet changing customer needs.

• Develop affordable ways to finance improvements.

• Involve the public in the planning process.

The Project Team will need Board Input Throughout the PEIR Preparation

Technical Analyses

Institutional Activities

PublicInvolvement

• Numerous issues from Phase 1 need continued Board input.

• Some items specifically relate to PEIR activities

• Other items, while not strictly tied to PEIR, need continued Board discussion

Schedule of Board Involvement

Expansion of Service Policy Guiding Principles (Board Action)

Page 5: April 18, 2006

5

The WRP Recommends Expansion into the SOI

The WRP goals need to be consistent with OID policies

A review of the current OID Annexation Policy is necessary

Recommend a 2 step process– Develop “Guiding Principles”– Revise Annexation Policy as

necessary

Provide long-term protection to OID’s water rights

Address federal, state and local water challenges

Rebuild/modernize an out-of-date system to meet changing customer needs

Develop affordable ways to finance improvements

Involve the public inthe planning process

Page 6: April 18, 2006

6

Guiding Principles are District Policy Statements

• GP #1: Expansion into SOI shall not negatively impact existing OID customers as it relates to water supply reliability, cost of service, availability of service, etc.

• GP #2: Transfers should achieve the greatest local benefit with the least amount transferred.

Page 7: April 18, 2006

7

Guiding Principles are District Policy Statements

• GP #3: When surplus water becomes available over the next 20 years, it shall be committed to meeting several priorities.

1. Transferred to meet the WRP Goals and economic needs of the District,

2. To insure the future local water needs for the cities of Oakdale and Riverbank,

3. To increase opportunities for expansion within the sphere of influence

4. And other needs as determined by the Board

Page 8: April 18, 2006

8

Guiding Principles are District Policy Statements

• GP #4: Water for SOI expansion shall be provided as a supplemental supply to SOI users.

• GP #5: Expansion into SOI shall only occur on developed agricultural land.

Page 9: April 18, 2006

9

Outside the OID service area (within SOI):

Fruits and Nuts: 6,900 acres

Corn and Oats: 3,700 acres

Page 10: April 18, 2006

10

Guiding Principles are District Policy Statements

• GP #6: Agricultural water for SOI expansion shall be prioritized based on considering all the following factors:

1. Least water demand2. Highest efficiency of use (trees over pasture)3. Large ag parcels over small ag parcels4. Contiguous over non-contiguous5. Least long-term maintenance costs to OID6. Least cost to serve by OID7. Ability to benefit local aquifers (in-lieu recharge)8. Self-sufficient during a drought – can pump their own

water and can pump into OID canal for use downstream

9. No ag water drainage leaving property

Flow Control and Measurement

Improve DSO ability to meet customer water needs

Enable growers to modernize on-farm operations

Reduce operational spills Supports revised Service

Standards All projects within OID Right

of Way

Page 15: April 18, 2006

Flow Control and Measurement Example Project

New concrete structure Motor operated flow

control gates Downstream

measurement flumes SCADA Flows coordinated with

reservoir releases

Customer Benefits: Enables consistent water

levels, ability to better respond to customer demands, grower in

control

Page 16: April 18, 2006

Main Canals and Tunnels Program

2-Mile Bar

Goodwin Dam

TunnelNo. 7

TunnelNo. 9

2-mile bar slide zone outside OID Right of Way

Main Canals &Tunnels are on separate CEQA track but will be discussed in PEIR

Working with Condor to prioritize projects relative to other WRP needs

Page 17: April 18, 2006

17

OID Groundwater Wells Program

Improve peak supply flexibility

Increase drought year supply reliability

Locations TBD by OID over course of Implementation

May require Right of Way acquisition

Page 18: April 18, 2006

18

District Drought Response Plan

• Additional District groundwater pumping capabilities

• Cooperative use of private groundwater wells• Expansion of Service into areas with

groundwater• Modifications to delivery schedules• Pursue land idling agreements as a

consideration for long or severe droughts

Page 19: April 18, 2006

Regulating Reservoir Recommendations

Van Lier ReservoirSouth Side: Adjust

Van Lier Operations

North Side: Re-establish Intertie to Woodward Reservoir

North Side:New Reservoir at Burnett-Cometa

split

Woodward Reservoir

New Reservoir

Page 20: April 18, 2006

20

North Side Reservoir Manage mismatches in

supply and demand Meet increases in

irrigation demand, providing greater flexibility and shorter response time

Provide temporary storage of excess flows during unscheduled cuts in demand

Will involve Right of Way acquisition

Page 21: April 18, 2006

21

Woodward Intertie

Page 22: April 18, 2006

22

Drainwater Reclamation Program Improve peak irrigation

season supply closer to the point of use, which increases operating and scheduling flexibility

Plan routing of excess lateral flows to the drainwater storage reservoirs

Some facilities will require Right of Way acquisition

Page 23: April 18, 2006

23

Surface Water Outflow Management Program

Regulate outflows from the OID service area

Provide predictable timing/quantity for managed re-use by downstream water users

Potential water quality benefits

Facilities will require Right of Way acquisition

Page 24: April 18, 2006

Financial Model was Used to Evaluate Revenue Options

• Rates and Charges- 54,100 acres in-District (-1,600 acres net)- 4,250 acres expansion ($1,600 buy-in, in-

District rate – equiv to $40/ac long-term contract w/ no buy-in)

- 3% annual escalation• Hydropower

- Based on current agreement- $12.5M to $5.5M annually

Page 28: April 18, 2006

Financial Model was Used to Evaluate Revenue Options

• Other- Property Tax and Miscellaneous- Assumed that by 2007, ERAF Terminates

• Water Transfers- Stanislaus River (Top) 30,000 to 50,000 af

($210/af)- Surface Water Outflow (Bottom) 0 to

30,000 af ($20/af)

California Environmental Quality Act (CEQA) Process

Disclose potential impacts of a proposed program/project Programmatic document to allow for

development/refinement of future actions (e.g. water transfers)

Obtain public and agency input Mitigate potential significant impacts (if any) to extent

possible

OID’s role:Consider the above when making a

decision on the program

Page 35: April 18, 2006

36

Preferred/Best Apparent Alternative = Proposed Program

Proposed program must be defined to allow for environmental review

Vast majority of individual actions or individual will require additional refinement (e.g. outflow basin locations and operations)

PEIR will identify overall anticipated impacts and identify avoidance criteria and programmatic mitigation

Future documents (primarily negative declarations) will tier from PEIR and use avoidance criteria and mitigation as applicable

Page 36: April 18, 2006

37

CEQA Path Forward

• Programmatic review• Those actions/projects that are essentially O&M will

be identified as such (e.g. Flow Measurement projects)

• Resource studies (landowner contacts for field reviews)

• Public draft to be released in November (administrative draft by end of September)

Page 37: April 18, 2006

38

Implementing Proposed Program Will Benefit OID’s Customers and the Community

Protect OID’s water rights. Enhance customer service for all users. Rebuild, modernize, and expand system

infrastructure. Protect the future water supply needs of the

cities of Oakdale and Riverbank. Keep water rates affordable through a

balanced effort of water transfers and service to “new” customers within OID’s Sphere of Influence.

Substantially increase water supply reliability and meet OID service in a worst-case drought.

Page 38: April 18, 2006

Summary

• Significant Board and public interaction• Have fully defined and characterized the

Proposed Program• Ready to start impact analyses
