Zone 7 Awarded Certificate of Excellence in Financial Reporting

Zone 7 has been awarded the Certificate of Achievement for Excellence in Financial Reporting by the Government Finance Officers Association of the United States and Canada (GFOA) for its 2015-16 Comprehensive Annual Fiscal Report (CAFR). The CAFR provides the public with the Agency’s detailed financial information as well as providing comparative analyses to previous years. The GFOA’s announcement noted that the Agency’s CAFR was judged to have met the high standards of the program, including “demonstrating a constructive ‘spirit of full disclosure’ to clearly communicate its financial story and motivate potential users and user groups to read the CAFR.”

Oroville Dam Update

On April 6, 2017, the Department of Water Resources (DWR) released the Oroville Spillway Recovery Plan.  The Plan describes the approach to recover the gated flood control and emergency spillway facilities to original design capacity by November 1, 2017 so that operations can resume as normal for the 2017-2018 water year. DWR recently announced that they have awarded a $275 million contract for the first phase of permanent repairs to the Oroville spillway; Zone 7’s share of this will be about $5.5M.

Crews are working 24 hours a day to repair the facilities and DWR continues to post progress reports on the repairs on a dedicated webpage as well as YouTube. The emergency repairs, alone, have already cost about $250 million with Zone 7’s share being another $5 million and DWR acknowledges that a large portion of the emergency repairs may have to be removed.

An independent Board of Consultants has reviewed the failure and provided a series of memos outlining their findings. DWR just released these reports and posted them on their website.

Report a Spill or Dumping

Zone 7 owns many flood control channels and creeks in the Cities of Livermore, Pleasanton and Dublin, and in unincorporated areas of Eastern Alameda County. If you see a spill or dumping in any waterway, follow the directions below to report it:

1. If a spill is currently happening, call 911.

2. If the situation is not urgent, call: 

  • Zone 7 Administrative offices at (925) 454-5000 during business hours, Monday-Friday, 8 a.m. to 5 p.m.
  • Water Treatment Plant Operator at (925) 447-6704, ext. 1, during non-business hours

Better Treatment for Algae is Under Design

It's spring and not only are we seeing our landscapes flourish, we are also seeing our first glimpse of water-borne algae in the water delivered to our local water treatment plants. The water treatment process ensures the water is safe to drink and meets all State and Federal standards. When water-borne algae are present in our source water supplies, we are adding powdered activated carbon to reduce the dirty, musty taste and odors but it is not 100% effective. To address this, we are upgrading our plants by adding ozone treatment over the next few years. Ozone is significantly more effective than other treatment technology at treating algal byproducts that cause the unpleasant taste and odor. The current algal bloom is temporary and should clear up naturally within a week or two. 
Water Supply Project Updates

To enhance water storage flexibility and improve long-term water supply reliability for the Livermore-Amador Valley, the 2016 Water Supply Evaluation Update (WSE Update) identified Sites Reservoir Phase 1, Los Vaqueros Reservoir Expansion Project Planning, and Lake Del Valle Storage Expansion as potential projects. With Board approval in 2016, Zone 7 has partnered with other agencies to explore these options.

Below is a summary of the quarterly update given to the Board on April 19, 2017 regarding the status and progress of these projects.

Sites Reservoir Phase 1

As proposed, Sites Reservoir is a new off-stream reservoir to be located 75 miles northwest of Sacramento and was identified as a possible source of additional water supplies as well as providing additional storage for Zone 7. With approval from the Board of Directors, Zone 7 staff successfully executed an agreement with the Sites Project Authority to participate in the project. Zone 7 has currently been assigned 12,570 AF of Class 1 water and 8,620 AF of Class 2 water. Class 1 water represents 50% of the reservoir’s expected yield (250,000 AF out of 500,000 AF total yield annually). Class 2 water represents the remaining expected yield, which is currently reserved for “public benefit” environmental uses, but may become available at a later time depending on the state’s level of participation.

Phase 1 of Sites Reservoir planning is focused on preparing the Proposition 1 grant funding application, the Draft EIR/EIS and the Draft Federal Feasibility Report in order to secure Proposition 1 grant funding. The Sites team continues to work closely with DWR to identify and quantify public benefits for the purposes of meeting the eligibility criteria for the Proposition 1 funding but work is on track to complete the application in June 2017 (well ahead of the August 14 deadline). An Administrative Draft EIR/EIS is planned for release in April 2017. House Resolution 1269 (Sacramento Valley Water Storage and Restoration Act) was introduced to the United States House of Representatives in early March 2017 to support Sites Reservoir and to tie the schedule of the Federal Feasibility Report to the Proposition 1 application schedule.

Los Vaqueros Reservoir Expansion Project Planning

In 2016, the WSE Update identified Los Vaqueros Reservoir in a list of facilities that could reduce risk of water supply shortage to Zone 7 as well as facilitate a regional desalination project by adding relatively local storage capacity. Contra Costa Water District (CCWD), with participation from Zone 7 and several other water agencies, is in the planning process to increase the reservoir’s current 160,000 AF capacity up to 275,000 AF and would include a regional intertie (Transfer-Bethany Pipeline) and improved pump stations and pipelines. The project is in the process of completing the necessary documents and developing the application for Proposition 1 funding which is due August 14, 2017. Proposition 1 stipulates that in order to be eligible for funding, storage projects must provide a public benefit. The Los Vaqueros Expansion Project would provide up to 120,000 AF of water per year to wildlife refuges, thus meeting this eligibility criteria.

A Public Draft Federal Feasibility Report is expected in the Fall of 2017. Zone 7 will continue to support the development of this documents as well as the preparation of the Proposition 1 grant funding application.

Lake Del Valle Storage Expansion

The Lake Del Valle Storage Expansion investigative studies included preparation of several preliminary draft reports to assess the feasibility of modifying operations of Lake Del Valle such that more water could be drawn out of the lake, thus increasing the available water supply. The result of those preliminary reports showed that while technically feasible, it would require tremendous coordination with DWR and the East Bay Regional Park District (EBRPD) to make the necessary modifications. The project would require additional feasibility studies to assess potential water quality and flood control impacts, full and eager participation from DWR and EBRPD, and grant funding such as from Proposition 1 (Water Quality, Supply, and Infrastructure Improvement Act of 2014) for the project to move forward. The grant process for Proposition 1 funding is highly competitive, with other projects much farther along in the planning and environmental review process still seeking funding, and could cost Zone 7 upwards of $300,000 to prepare.  Given the competition for funding, Zone 7 would be unlikely to be awarded funding. After weighing the potential costs, benefits, and risk, Zone 7 staff and the Board of Directors decided not to move forward with seeking Proposition 1 funding at this time. Of course, this project could be pursued at a later date should there be interest from DWR and EBRPD and other funding opportunities become available.
