5. Bull Mountain Annexation-Jim Hendryx
Jim Hendryx, Community Development Director for the City of Tigard, presented
information about the potential Bull Mountain Annexation of the unincorporated area. (A
copy of the PowerPoint presentation is included in the file.)
Approximately one-third of Bull Mountain is already within the incorporated area of the
city, which has been annexed over a period of years. The remaining area has been
divided into four sub-areas to allow for studies. Two feasibility studies have been
performed to get a better idea of the needs in the unincorporated area of Bull Mountain
as well as the service needs for the area now and 20 years into the future.
There have been a number of intergovernmental agreements between the City of Tigard
and Washington County since the 1980's, including an urban planning area agreement,
planning, permit and engineering development services, road maintenance, and an
urban services agreement.
The city and county have been involved in a number of detailed studies to proceed with
the goal of annexation. The annexation plan is a comprehensive blueprint of
annexation, a growth management tool that includes when and how it would occur, what

7. Water Supply Update- Dennis Koellermeier
The Portland contract negotiations are one to two years away from an agreement with
the wholesale users, which will require the current agreement to be extended. A
comprehensive comparison of sources and costs has been compiled comparing the
Joint Water Commission, the Willamette and the City of Portland, which will be shared
with the TWD soon.
About 95% of water comes from the JWC. About 5 mgd is coming from wells and the
Joint Water Commission.
ASR—The second ASR (10-mgd well) site is moving ahead nicely and we will start
drilling soon. We will start recharging the ASR well soon.
Rider Reservoir—The process has slowed down because there have been a few
problems with school district negotiations and the land use issue.
8. IWB Update— Norm Penner
Galardi Consultants gave a presentation at the IWB meeting about the rate model. They
have designed a software system that can be changed with circumstances to project
future needs and can also be used for setting rates and determining revenue bonds for
capital improvements.
There was a discussion about fluoride and Mr. Koellermeier said that membership with
the JWC is an issue where fluoride is concerned. He also said he would be inviting
Dave Winship from Beaverton to make a presentation to the IWB at the December
meeting.
9. Non-Agenda Items
The board discussed an article 'Wilsonville Water Samples Prove Hazard-free" and also
the possibility of reconsidering the Willamette River as a long-term option.
Commissioner Penner motioned to reconsider the Willamette River as a long-term option
and Commissioner Marc Delphine seconded the motion. The board decided to hold off
a vote until more facts could be gathered. They were interested as well in the
documentation of the Willamette River data and investigation of the costs involved, etc.
Mr. Koellermeier was asked to provide the information at the next meeting, if possible.
Mr. Koellermeier also reported that Sherwood is also pushing to go to Willamette River
as a water source.
10. Set next meeting date—January 26, 2004, at 7:00 p.m.
An update on the fluoride issue was requested as a topic for the meeting.

Tigard Water District Minutes -3 - November 24,2003
Facts about Fluoride
• Fluoride is a naturally occurring element. Fr
Flourine
• Water systems throughout the United States have A.tomk.Number: 9
added fluoride to their water supplies since 1945. This Atomic Jviass: 19
process is known as "fluoridation".
• American water supplies have low concentration levels of fluoride.
• Fluoride, when administered at low levels of concentration, is proven to
help prevent tooth decay.
• The American Dental Association (ADA) endorsed fluoridation in 1950,
reaffirming its endorsement in 1997. The
American Medical Association endorsed
fluoridation in 1951, and reaffirmed its
.. .:� endorsement in 1996. The U.S. Public Health
t ��%, Service has also endorsed fluoridation. The
American Water Works Association AWWA)
-. endorsed fluoridating public water systems in
1976. The endorsement was reaffirmed in 1982.
• In April 1999, the Center for Disease Control and Prevention (CDC)
proclaimed fluoridation to be one of the top ten greatest public health
achievements of the century. j
i
• In 1995, the U.S. Surgeon General estimated that 62 percent of Americans -
-approximately 167 million people--had access to fluoridated water. 1
• Drinking water's fluoride content is limited under federal law. The
i
maximum level of fluoride deemed acceptable by the U.S. Environmental
Protection Agency (USEPA) is 4 milligrams per liter
(mg/L). The CDC has established the "optimal level" for ' _ ,
fluoride content in drinking water to be the in the range ,'
of 0.7 mg/L to 1.2 mg/L. ,
• Despite fluoridation's benefits to dental health, exposure � „
to high levels of fluoride can cause dental fluorosis, a
condition which leads to mottled tooth enamel, tooth
The History of Fluoride in America's
Public Water Systems
In the early 1900's a dentist in Colorado
observed that children in towns with a high ' i
amount of naturally occurring fluoride
experienced mottled teeth however it was
noted that the residents of these communities
also had strong teeth, few cavities, and very
...
few had lost any teeth. Additional research
showed a remarkable relationship between the
concentration of waterborne fluoride and the absence of dental caries (cavities).
Once the role of fluoride in water was determined in 1945, cities throughout the
United States began adding fluoride to their drinking water supplies.
It is the responsibility of the US Environmental Protection Agency (EPA), under
the Safe Drinking Water Act (SDWA), to regulate the amount of fluoride in
drinking water. The Center for Disease Control and Prevention (CDC) prescribes
an addition of fluoride is from 0.7 mg/1 to 1.2 mg/i to have appreciable dental
significance. At a fluoride level of approximately 1.0g
the optimum
condition exists for maximum reduction in cavities with no aesthetically
significant mottling. In 1986 the EPA set a Maximum Contaminant Level (MCL)
of 4.0 milligrams per liter (mg/L) to protect against crippling skeletal fluorosis,
an adverse health effect. In addition, EPA set a non-enforceable Secondary MCL
of 2 mg/1 to protect against dental fluorosis.
Today, nearly two-thirds of the Unites States population
which is served by public water supplies consumes
water with "optimum levels" of fluoride. In the
t � �r
State of Oregon, 22.7% of Oregon sX f 'f a population is
b � � �.
served by public water systems with ;' '!1 P 4 `� optimum
levels" of fluoride. In the metro area, ,. the Tualatin
Valley Water District and the City of Forest Grove both
currently fluoridate their water.
The American Dental Association, the American Medical Association,the United
States Public Health Service and the American Water Works Association
(AWWA) have all endorsed the addition of fluoride to drinking water.

Tigard Water Service Area Receives
Fluoridated Water
For over ten years the City of Tigard has been pursing ownership in a long-term
water source capable of meeting the current and future water demands of our
customers. In past month, the City of Tigard found itself one step closer to
obtaining that goal. In January 2004 the City of Tigard became a member of the
Joint Water Commission (JWC). The JWC is a water system whose members
include the Cities of Beaverton, Hillsboro, Forest Grove and the Tualatin Valley
Water District. This filtered system draws its water from the Trask and Tualatin
Rivers Watershed.
As a member of the JWC, the City of Tigard will purchase approximately 4
million gallons of water each day, which is close to one-half of our annual water
supply. This water will be delivered via the City of Beaverton's water
distribution system.
It is important to note that during the past two years the City of Beaverton has
been debating on whether or not to add fluoride to its drinking water supply. In
late 2003 the Beaverton City Council approved the development of a fluoridation
plan. Fluoride injection is scheduled to begin as early as April 2004, at which
time Beaverton will be delivering a fluoridated supply of water to the City of
Tigard.
Tigard Water Service Area residents will be kept informed as more information
becomes available. To learn more about fluoridated water, check out the City's
website at www.ci.tigard.or.us/water. If you have any questions and/or concerns,
please feel free to contact the City of Tigard's Water Quality Program
Coordinator, Sally Mills at 503-718-2604 or sallv(i4ci.tigard.or.us.

Sources of Fluoride
Fluoride is available in various forms. Forms of fluoride that can be applied
directly to teeth include:
• Toothpaste;
"C'' ' • Mouth rinses; and
!!%,/, • professionally applied fluoride treatments (available in the
,. dental office).
1
These methods of delivering fluoride are more ;
expensive than water fluoridation and require a \ ','
conscious decision to use them. However, the :,..r., -,,
itt
widespread availability of fluorides, via water
fluoridation, toothpaste and other sources, has resulted : : ,.
in the steady decline of dental caries throughout the ' ""
United States.
Children,whose dentists have evaluated as being at high risk for tooth decay
and whose home water supplies contain low amounts of fluoride, can take
dietary fluoride supplements. This daily supplement,which can be prescribed
by a dentist or a physician, should be taken only by children if the home water
supply has been verified to contain a low concentration of fluoride.
