ESYS10 Case Study Warmup, January 12, 2006

San Diego County water resources

 

General

                  Water rights have always dominated politics in the Western U.S., and these past several years more than ever.  Recently, the Department of the Interior decreed that California would receive 13% less Colorado River water than in previous years.   This spurred fast action amongst California water resource agencies, and resulted in an historical agreement for transfer of water from the Imperial Valley, where it is primarily used for agriculture, to San Diego County.  San Diego County's population is expected to grow 30% over the next 30 years.

                  Recognizing the looming crisis in water resources over the next 20 years, the U.S. Department of the Interior has started a Challenge Grants program that "provides funding on a 50/50 cost share basis to irrigation and water districts for projects focused on water conservation, efficiency, and water marketing." (http://www.doi.gov/water2025/grant.html).

                  You have been appointed to a committee that is writing a grant proposal for funding to San Diego County through this program.    As a committee you will have to decide (1) what area to target (conservation, efficiency, marketing), (2) what to propose.  Your predecessor committee was responsible for finding funding for the Coachella Canal lining project (see editorial below).

 

Issues

                  "The California agencies that use Colorado River water are working to reduce their reliance on the river. California currently takes approximately 5.2 million acre feet (maf) per year, even though its entitlement is only 4.4 maf. The primary vehicle for this effort is California's Colorado Water Use Plan, which is designed to reduce California's demand on the river to its 4.4 MAF apportionment when surplus water or other states' apportionment is not available." (San Diego County Water Authority, Water Management, http://www.sdcwa.org/manage/mwd-colriver.phtml, 1/6/05)

 

                  "In October (..2004..), ground was broken in the Imperial Valley for the relining of the Coachella Canal, a project that will mean 26,000 acre-feet of water for San Diego County. That's a bigger deal than it may sound, for relining this and a section of the All-American Canal is only part of a landmark agreement to transfer agricultural water, much of it formerly lost to seepage, to San Diego."

                  "From the relining alone, San Diego stands to gain enough water to supply more than 150,000 households a year. That's in addition to the supply for some 400,000 households a year which the water authority has the right to buy from the Imperial Valley Irrigation District. With these hard-won supplies, San Diego County acquires the independence from the Los Angeles-based Metropolitan Water District that it has long sought.

                  "Also in this deal are 800,000 acre-feet the state will buy from Imperial Valley, then resell to the Metropolitan Water District to distribute in Southern California. Profits will be used to help restore the Salton Sea. And all of this water supply/sale/conservation intertwines with the demand of the federal government that California reduce its overreliance on the Colorado River, the source of these water supplies, or face cutoffs."  (Editorial, San Diego Union Tribune,12/26/04)

 

"... For instance, white pelicans were a rarity along the San Diego County coastline. But in the past few years, more and more have shown up on the Christmas bird count. The partial collapse of the fishery at the Salton Sea in Imperial County, where the pelicans have been more numerous, could be forcing the birds to forage for food in a wider area, Pryde said."..."San Diego County, with 494 species recorded over the past 50 years, usually ranks in the top 10 of counties nationwide. There are slightly more than 650 bird species in the United States."  (Terry Rodgers, San Diego Union Tribune, 12/31/04)

 

"...The results of a recent public opinion survey conducted for the San Diego County Water Authority, shows that many San Diego County residents support the development of local water resources over increasing imported water supplies. Support for local water supplies remains high, even if it is more expensive than increasing imported water supplies.  A majority of respondents to the survey said it was better for local water agencies to invest in seawater desalination than to purchase additional imported water. Survey respondents also strongly support using recycled water for irrigation of public and residential landscapes, parks and recreational areas."  (San Diego County Water Authority news release July 28, 2005; http://www.sdcwa.org/news/releases.phtml)

Your committee includes:

Alex: a San Diego real estate developer (builder)

Bailey: agricultural agent for Imperial County

Chris: president of the San Diego Audubon Society

Dana: a San Diego County supervisor

Loren: a San Diego County Water Authority resource manager

 

A. (Today) Consider the following questions in your character's group:

1. What personal biases does your character bring to the table?

2. What information does your character need to represent that point of view?

                  A. technical or science issues for which you need objective information.

                  B. community, governmental issues

3. Come up with several ideas for grant proposals.

 

B. (Tuesday) Consider the following questions in your cross-cut group:

1. Attempt to reach a consensus on the type of proposal you would like to write.  If you can't reach consensus, then just pick one proposal.

2. What information do you need (as a group) to write a credible proposal?

3.  Choose 1 or 2 spokespeople and present your results to the class.

 

Assignment, due Tuesday, January 17:

1. Summarize the discussion in your character's group (points A1,2,3 above).

2. Find at least two credible resources with science/technical information pertinent to your point of view.  I suggest finding one source that is as objective as possible (e.g. a government agency), and a second resource that is more biased to your character's point of view. 

3. Find at least one resource with information, news, opinion relevant to the topic.

4. Summarize the information from your resources.  Please make sure to include references in your writeup.

 

In subsequent case studies, you will not be writing until after your cross-cut group meets, and the assignment would be due one week after the final meeting of the group.
