Tigard Area Historical Preservation Association
• ary Lass, a.member of'the Association, reported that the Tigard�Area Historical
reservation Association has been leasing some property on 103 Avenue.and
anterbury,Lane from the Water District. 'The John Tigard'House,is currently located
sere:
he'Association is requesting permission to erect another building on:the-site,to:house
isplays and allow them to turn the house over entirely for a historic house instead of the
.irrent combination house, meeting area`and display.area. The proposed building would,.
a approximately 40,',x25' and.sitin the back comer behind'the,house..It.would"taave.a
athroom,,small kitchen and laege-.display.area on the.main floor with an;attic area for
FFice and storage. One side of the.structure would have an overhang for out-side
isplays of farm equipment, etc. It would also be necessary to;pave a portion of the yard
provide three ADA parking,spaces. The church across the street has already agreed
let them use the church parking lot for events thaffdo not conflict with.their services.
lost events do not conflict. They would also need to hook up to the City sewer.
hese are preliminary. plans. At this point�nothing is'finalized. The house.would'be
sed as a museum house from-that period, keeping the displays in'.a separate structure.
urnishings for the house have been donated or purchased.from local shops. The
ouse was.built;in 1880 and was,originally located where the Elmer's;Pancake,HOuse is
ow located. It was moved in 1978, then moved•to its present location in- 1580 when the
-:ase was obtained from the Tigard Water.District.

d Wegner reminded the Board that another member of the Historical Association,
athy Palmer approached the Board eight or ten months ago. Through research,
wveral questions have arisen:
1. Who is going to own the building? •
2. Who is going to own it if the Historical Society were to collapse, fold; or
lose interest?
is going to be a permanent structure on leased property. The John Tigard House
)uld be moved off"the property, however, it would be difficult to move the proposed new
gilding because of°the utilities.
ne property is an asset of the Intergovernmental Water Board that would be divided up
-3tween the,involved entities if something happened.,,There is, however, a special lease
)r a portion of the property that has been divided off to be leased to the Historical
ssociation, which is with the Tigard Water District.The attorney said the IWB should
aggest either approval or disapproval to'the TWD-since-they hold the lease for a small
ortion,of the Canterbury property. The TWD can only approve the lease for the area
iat is within the original lease, which basically is the fence,line of the picket fence.
herewas a problem at the meeting. Although there was a quorum to run the meeting,
sere was not a quorum'of the governmental bodies to recommend dividing an asset.
,ommissioner'Patrick Carroll had'not arrived yet.)
ommissioner Schederich asked if there was a lease payment being made. Mr.`Wegner
iformed•the:Board the,lease.was $1.00 per year, but he wasn't sure where the money
as,,going.
omrhissioner<Schederich asked if there.were competitors competing to•use-the •
roperty. Mr. Wegner,said there were no other interested•parties and added that the
eighbors.would like it`built.-.He explained to Commissioner Penner that°if''the IWB
icommended proceeding, the TWD would need to allow another structure on the John
igard House leased property site. it will not require a new lease, only an amendment to,
ie current lease.
ornmi`Ssibnelr Pen ner'recommended taking the matter before the TWD at the next
--heduled meeting. That was the consensus of the Board. He requested more specific
iformation. Mr. Wegner said he would provide him with those specifics and would also
ave an addendum to the lease prepared for the TWD.
:ommissioner Schederich request Staff send fetters to all the government entities
idicati'ng the recommendation of the IWB to consider proceeding.
Leak Adjustment Request
Irs. Zuffrea addressed the Board requesting'�an adjustment to her water bill. She
3ferred to copies of documents relating-to the utility bills and water.line repairs. She
.ceived a call from Sue in the Utility'Billing'Department-about a possible leak,detected
./hen the meters,were be ng•read. Plumbers would not come out and told them they
eeded a leak detection company. Her husband found the leak. They eventually found
plumber who would come repair.the line (it was Father's Day). The repair otthe line.
as $3,375 and not covered'by insurance.., Their house sits back from the street and the
creased.rate is due to the,increased distance from the street.
• ie Utility Department said they could only'give a credit'of'$9.18. The $9.18 credit is
ised on a formula,previous ly'approved by the Board.
r..Wegner stated that leaks are typically discovered in someone's yard'when the
eters are read or—from—visible evidence in the yard of puddles'. Mr. Miller said he
ialyzed,the billing!'and it indicates'the problem happened over two billing cycles:
omm_ .issioner Schederich asked Staff to.give an average usage amount in order to
ase a fair credit amount. He also asked what the board's authority was for giving'a
-edit. Mr. Wegner told him they could do basically anything they wished on a.hardship.
I ere was a brief discussion regarding the average usage amount and how to calculate
fair credit amount. It was,estimated that the overage amounted`to a0proximately'102
abic feet'of water.. Commissioner Drangsholt moved to issue a.credit.of$70.00:;.
ommissione'r Penner seconded°the motion.
he $70.00 credit is a little more than half of the overage. Staff will notify Utility Billing of
ie credit and they will adjust the account..
Off Leash Area Request- Mike.Miller
J ohn Roy asked Mike.Miller to discuss,the possibility_ of•utilizing one of'the reservoir sites
s,a potential off least site for dogs. The City had a pilot'program'at Cook Park, That
kation has been discontinued as an Off Leash Park Area. The citizens who used the
ook Park area voiced their'opinion very strongly to the City.Counci1 that the City'should•
rovide another area., A Task Force has•been formed. A temporary Off Leash,Area was
c stablished on surplus:property next to the Public Works offices. It is'being:used
igularly everyday-. They are looking for other sites.
he Bull Mountain Reservoir site is a.large)facility with a,lot of open area. They°would
�e permission to pursue:that site as an Off Leash Area. Mr. Miller distributed maps
rowing the area and.the proposed fenced area: The six-foot chain link fence would
aep the users of the site away from,all.electrical controls; pumping facilities,the vault,
nd'also keep them_from getting on:top of the reservoir.
'ommissionerSchederich asked what the elevation;of the dome was Mr.,Miller
xpl'ained that the north side was exposed 10=15 feet and on the south side there was a
ix-foot exposure.
:ommissioner Penner asked.if this tank was the same one that was originally built to
ave a tennis court on top and was never used for that purpose because the neighbors.
iised such.a fuss. Mr. Miller indicated'it was the same one. John Roywould take the
roposal through Land Use process for approval. Park.funds would be used.to install
• ie fencing.
he reservoir area.currently is not irrigated but they may wan irrigate it to keep'it
reen if used for an off-leash area. The reservoir site is quite large; approximately 3.5
cies.
•tarnrivornmontal'WabPr Rnnrrl Z r1.•tr.l.m'f4 7nnn
r: Wegner stated that this site is only a temporary site. The Off-Lease Area
:)mmittee's goal is to seek several permanent sites somewhere. This temporary
cation could be used for up to a couple of years.
ie Ash Street temporary off-leash location is in use all times of the day and evening. •
sere is a sign with temporary rules, i.e.; dogs must.be.brought in on a leash and leave
i a leash. The location would be manned as a park and would close at dusk. Pooper-
:ooper bags would be provided. The Committee would monitor and police the area.
iey have been good neighbors.
ie biggest Cook Park complaint was that it was not an enclosed area,and allowed the
)gs to run the entire greenway. There were 80 people at the Council meeting. This
ight be a good public relations tool for the Tigard Water Service Area.with a possible
!te increase coming and water supply capital programs.
ommissioner Penner asked'about.dog licensing. The licensing is through the county.
ie leash law is through the County and the City uses that leash law. It is enforced by
-e County Animal Control.. Commissioner Penner thinks the users of the facilities
could be licensed. Mr. Wegner said they are looking for that type of regulation at the
3rmanent`locations. Research has been done and it has been found that in some
cations throughout the country in order not to have problems with dogs attacking other
cgs or people they federally identify the dogs. Commissioner Penner wants to be sure
ie"dog owners are being good citizens,.licensing, heir dogs and keeping the animals
ider control.
d Wegner stated they are asking the Water Board to•allow the Parks Division°to begin
,eprocess'ofgetting a Conditional Use Permit to allow the area indicated on the map..to
Fused as°a temporary dog park-area,until'suitable permanent areas can be located.
ne"Parks Department will fence the area andmaintain:it:
ommissioner Drangsholt had no objections to the area being used in that way as long
s it is not going to affect the operation of the reservoir. Mr:.Wegner assured her it
°ould not:
ommissioner Penner also agreed with the use, but with one provision, that the approval
:)t be construed improperly and that the neighbors in the area need to have a-say in the
tuation.
ommissioner Penner motioned to give the Parks Department approval to
roceed. Commissioner Drangsholt,seconded the motion. The motion was
nanimouslyapproved.

Tigard Water System System Development Charge
Update
PREPARED FOR: Mike Miller,City of Tigard
PREPARED BY: Art Griffith,CH2M HILL
COPIES: Ed Wegner,City of Tigard
Craig Prosser,City of Tigard
DATE: September 1,20W
Introduction
The City of Tigard has authorized C112M HILL to complete a System Development Charge
(SDC)Update for the Tigard water system.The existing SDC was developed in 1996 and
since that time,the City has continued planning for a long-term water source of supply
project,has constructed additional storage facilities,and has completed a water system
hydraulic analysis which has developed revised proposed capital improvements.
The Tigard water system serves areas inside the Cities of Tigard,King City,and Durham,
and also serves portions of unincorporated Washington County.Currently,the system
serves approximately 15,000 customers.The majority of the system's water supply is
currently purchased from the City of Portland,with additional production from the system
wells and additional water purchase from the City of Lake Oswego and the Tualatin Valley
Water District.For the definition of rates and SDCs the system is divided into the lower 410
pressure zone and the higher Bull Mountain area.The Bull Mountain area includes the 550
high pressure and gravity pressure zones,and the 713 high pressure and gravity pressure
zones.Separate rates and SDCs are maintained for the Bull Mountain area because of the
additional pumping expense and system facilities required to serve the higher elevations.
Table 1 summarizes the existing system Development Charge,including the reimbursement
fee and improvement fee,but not including any installation charge.

Legislative Considerations
In 1989,the State of Oregon enacted legislation that authorizes local governments to define
and assess SDCs and the legislation also places limits on the ways revenues generated
through SDCs can be used.A copy of ORS 223.297-314 is included in the Appendix of this
Memorandum.A SDC is defined in ORS 223.299,and is an amount charged to a new user at
the time of connection to the water system in excess of the cost of inspecting and installing
the connection.The SDC does not include fees assessed or collected through local
improvement districts.The statute further breaks down the SDC into an improvement fee
and a reimbursement fee.The improvement fee is a fee for the cost of capital expansions to
be constructed.The reimbursement fee is a fee for the costs of capital improvements already
constructed or under construction.
ORS Chapter 223 specifies that the reimbursement fee must be established by an ordinance
or resolution that sets forth the methodology that will be used to calculate the charge.It
further specifies that the methodology must consider the cost of existing facilities,prior
contributions by existing users,the value of unused capacity,ratemaking principles
employed to finance the capital improvements,and other relevant factors.The objective of
the methodology must be that future system users contribute no more than an equitable
share of the cost of existing facilities.
The improvement fee methodology must also be specified in an ordinance or resolution that
considers the cost of projected capital improvements needed to increase the capacity of the
system.ORS Chapter 223 further requires that a credit be provided for the construction of
qualified public improvements(contributions).A qualified public improvement is one
required as a condition of residential development approval,identified in the system's
SEPT 12000 SDC FINAL REPORTAOC 2
TWRD WATER SYSTEM SYSTEM DEVELOPMENT CHARGE UPDATE
capital improvement program,and either(i)not located on or contiguous to the property
being developed or(ii) located on or contiguous to the property being developed but
required to be built larger than necessary to serve the property being developed.
Revenues generated through the reimbursement fees must be spent only on capital
improvements to the system or repayment of debt on those improvements.Revenues
generated through the improvement fees are dedicated to capacity increasing capital
improvements or repayment of debt on capacity increasing capital improvement.An
increase in capacity is established if the improvements increase the level of performance or
service provided by existing facilities or provide new facilities.The portion of such
improvements funded by improvement fees must be related to current or projected
development.
Other provisions of ORS Chapter 223 require that:
• A local government implementing an SDC must develop a capital improvement plan
(C1P)or other comparable plan that lists the improvements that may be funded with
improvement fee revenues and the estimated timing and cost for each improvement.
Any capital improvement being funded wholly or in part with SDC revenues shall be
included in the plan adopted by the local government.
• SDC revenues must be deposited into dedicated accounts,and local government must
provide an annual accounting of revenues and expenditures.
• Local government must provide for an administrative appeal procedure whereby a
citizen or other interested party may challenge an expenditure of SDC revenues.
• No legal action challenging the methodology used to calculate SDCs may be filed after
60 days from the enactment of or revision to the SDC.
• The provisions of ORS 223.297 to 223.314 are not applicable if they impair the local
government's bond obligations or the ability of the local government to issue new bonds
or other financing.
Proposed Capital Improvements
Capital improvements are identified in the City of Tigard Water Distribution System
Hydraulic Study(2000 Hydraulic Study)prepared by Murray,Smith&Associates,Inc.All
capital projects identified in the 2000 Hydraulic Study are incorporated into this SDC except
demolition projects,Aquifer Storage and Recovery studies,and water main replacement
projects.These three types of projects are not,for the purposes of this SDC analysis,defined
as capacity-increasing projects.
A$40 million water supply project has been identified by the City,which will provide a
long-term water source owned by the City.This water supply project would provide an
estimated 20.0 mgd of water on a maximum day basis to the Tigard water service area.Debt
financing is projected,with three annual interest-only payments followed by levelized
principal and interest payments over the subsequent 22 years at a 6%interest rate.Debt
issuance costs include a capitalized bond reserve estimated at 8.79/6 of bond proceeds and
other costs of issuance estimated at 2.0%of bond proceeds.
SEPT 12000 SDC FINAL REPORTDX 3
TIGARD WATER SYSTEM SYSTEM DEVELOPMENT CHARGE UPDATE
Prior to adoption of this SDC,state law requires that the City adopt a Capital Improvement
Plan that contains the proposed capital projects that form the basis of the SDC.
.Methodology Used To Calculate SDC
The SDC is comprised of a reimbursement fee and improvement fee.The reimbursement fee
is intended to recover the costs associated with the growth-related (or available) capacity in
the existing system,and the improvement fee is based on the costs of capacity-increasing
future improvements needed to meet the demands of growth.
Equivalent Dwelling Units
Equivalent Dwelling Unit(EDU)data was calculated from information contained in the
City's May 2000 Water Distribution System Hydraulic Study(2000 Hydraulic Study)and
current meter size data provided by the City of Tigard.Table 2 summarizes March 2000
meter data provided by the City,showing 21,465 meter equivalents system wide.
Table 5-1 of the May 2000 Water Distribution System Hydraulic Study reports a projected
2000 peak day demand of 13.84 mgd.Dividing the 2000 maximum day demand by the
existing 21,465 meter equivalents results in a maximum day demand of 645 gpd per meter
equivalent.Throughout this analysis,an EDU is defined as a water system connection with
a5/8x3/4-inch meter with a maximum day water consumption of 645 gpd.

System Capacity
The 2000 Hydraulic Study estimated water system demands for each water system pressure
zone at existing demands and at saturation for a water service area that encompasses the
existing Tigard water service area and'Urban Reserves 47,48,and 49.The saturation
analysis was based on planning data provided by the City of Tigard,and projects an
increase of service area population from a current estimate of 46,144 to a saturation estimate
of 85,147.
For the 410 Zone,the existing maximum day demand is an estimated 7.80 mgd,and the
projected saturation maximum day demand is 16.17 mgd.The projected increase in system
capacity in the 410 Zone,measured by maximum day demand,is 8.37 mgd.For the Bull
Mountain area,the existing maximum day demand is an estimated 6.04 mgd,and the
projected saturation maximum day demand is 11.93 mgd.The projected increase in system
capacity in the Bull Mountain area,measured by maximum day demand,is 5.89 mgd.
Water system growth rates projected in the 2000 Hydraulic Study are based on population
projections provided by Metro and include an annual 1.2%growth rate.
Reimbursement Fee
The general methodology used to develop the reimbursement fee includes the following
four steps:
1. Determine the value of growth-related capacity
2. Define system capacity
3. Calculate the unit cost of growth—related capacity
4. Develop reimbursement fee per EDU
The value of growth-related capacity in this analysis is based on the system's non-
contributed depreciated plant investment.The existing plant investment used in the 1996
SDC calculation was used as the basis for the estimated current plant investment.
Adjustments from the 1996 plant investment include estimated depreciation between 1996
and 2000,addition of facilities(i.e.the Menlor Reservoir)completed since 1996,and addition
of existing capital reserves.Table 3 shows the derivation of the reimbursement fee,
including the derivation of the net system investment of$24,370,445.
The system capacity,described above,is the estimated saturation maximum day demand of
28.1 mgd.Use of saturation maximum day demand as a measure of system capacity is a
change from the existing methodology,where the existing system capacity is used.Dividing
the net system investment by the system capacity results in the unit cost of growth-related
capacity of$867,276 per mgd of system capacity.
To determine the reimbursement fee per EDU,the net investment per unit of system
capacity is multiplied by the estimated capacity requirements,645 gpd,of an EDU.The
resulting improvement fee is$561 per EDU.

Improvement Fee
The general methodology used to develop the improvement fee is similar to that for the
reimbursement fee,and includes the following four steps:
1. Determine the costs of growth-related improvements
2. Calculate the unit cost of additional capacity
3. Calculate debt service credit
4. Develop reimbursement fee per EDU
Cost of Growth-Related Improvements
Capacity-increasing project costs were identified in a Draft City of Tigard Distribution
System Hydraulic Study Financial Plan Technical Assistance memorandum(2000 Technical
Memorandum)prepared by Murray,Smith&Associates,Inc,a copy of which is included in
the Appendix.The 2000 Technical Memorandum identifies allocations of project costs to the
410 Zone and the Bull Mountain area and allocations of project costs to existing capacity and
future capacity.The allocations between existing capacity and future capacity are generally
based on the ratio of existing to saturation maximum day demand in the area benefiting
from the project.Projects required to serve the Urban Reserves are allocated entirely to
growth.The City's water main oversizing program was allocated between existing and
future capacity by CI-12M HILL based on the ration of system wide existing and saturation
maximum day demand.Table 4 shows,for each distribution system project included in the
SDC,the project cost in 2000 dollars and the allocations of project costs between 410 and
Bull Mountain areas and between existing and future capacity.Use of 2000 dollars is a
change from the current methodology,where an inflation-adjusted cost was used.This
change was made because of the long-term nature of the capital improvement plan that is
based on a saturation analysis and a capital improvement plan schedule covering over
twenty years.
The City is pursuing the feasibility of a number of potential options for securing a
guaranteed long-term water supply.For the water supply project,the derivation of the
capacity increasing project cost is defined by the following series of calculations.
• Define the project cost,estimated at$40,000,000 and the amount($3,900,000)expected to
be funded from existing Tigard water system capital reserves.The remaining
$36,100,000 would be funded by debt issuance.
• Estimate the costs of debt financing,including the capitalized bond reserve and costs of
debt issuance for the bond issue that would supply$36,100,000 of bond proceeds for the
water supply project.The estimated financing costs are$4,325,500,for a total project cost
of$44,325,500.
• Calculate the proportion of the water supply project to be allocated to future capacity
The 20.0 mgd water supply project would supply the existing maximum day demand of
13.84 mgd plus an additional 6.16 mgd.30.8%of the water supply project is allocated to
growth(30.8%=6.16/20).

TIGARD WATER SYSTEM SYSTEM DEVELOPMENT CHARGE UPDATE
System Capacity and Unit Costs of Additional Capacity
For the distribution system improvements, the increase in system capacity is the difference
between existing saturation maximum day demand and estimated existing maximum day
demand.This information is provided.in the 2000 Hydraulic Study for the 410 Zone and
Bull Mountain area.
Table 5 shows the unit costs of capacity for the water supply component, the 410 Zone
distribution system component,and the Bull Mountain area distribution component.The
unit cost of future capacity is calculated by dividing the project cost allocable to growth by
the increase in system capacity.
Debt Service Credit
A debt service credit is applied to the improvement fee in recognition that the water supply
project will be debt financed,that the water supply project benefits existing as well as future
customers,and that future customers will be repaying debt service for facilities that benefit
existing customers.The debt service credit is detailed in Table 6,and includes a calculation,
for each year where outstanding water supply project debt service exists,of the amount of
debt service principal benefiting existing customers that paid per EDU.The debt service
credit is the present value of these debt service payments calculated using a nominal interest
rate of 5%.Table 6 shows that the debt service credit is$552 per EDU.
Improvement Fee Per EDU
The improvement fee per EDU is calculated by multiplying the unit cost of future capacity
by the estimated capacity requirements,645 gpd,of an EDU,and applying the debt service
credit.Table 5 shows that the improvement fee for the water supply project(not including
the debt service credit discussed below)is$1,432 per EDU.This component of the
improvement fee would be applied system wide.For the 410 Zone,an additional
distribution system component of$600 per EDU would be applied,and for the Bull
Mountain area,an additional distribution system component of$1,322 per EDU would be
applied.
Proposed System Development Charge
The proposed SDC per EDU is the sum of the reimbursement fee and the improvement fee,
and is summarized in Table 7.Table 8 presents the proposed SDC applied to each water
meter size.Prior to adoption of the SDC,CH2M HILL recommends that the City's legal
counsel review this memorandum and that a Capital Improvement Plan be adopted that
contains the capital improvements upon which the improvement fee is based.

existing users,the value of unused capacity,rate-making principles employed to finance
publicly owned capital improvements and other relevant factors identified by the local
government imposing the fee.The methodology shall promote the objective of future system
users contributing no more than an equitable share to the cost of existing facilities.The
methodology for establishing such fees shall be available for public inspection.
(2)Improvement fees shall be established by ordinance or resolution setting forth a
methodology that considers the cost of projected capital improvements needed to increase the
capacity of the systems to which the fee is related.The methodology for establishing such fees
shall be available for public inspection.
(3)The ordinance or resolution that establishes an improvement fee shall also provide for a
credit against such fee for the construction of a qualified public improvement.A"qualified
public improvement"means a capital improvement that is required as a condition of
development approval,identified in the plan adopted pursuant to ORS 223.309 and either:
(a)Not located on or contiguous to property that is the subject of development approval;or
(b)Located in whole or in part on or contiguous to property that is the subject of development
approval and required to be built larger or with greater capacity than is necessary for the
particular development project to which the improvement fee is related.
(4)(a)The credit provided for in subsection(3)of this section shall be only for the improvement
fee charged for the type of improvement being constructed,and credit for qualified public
improvements under subsection(3)(b)of this section may be granted only for the cost of that
portion of such improvement that exceeds the government units minimum standard facility size
or capacity needed to serve the particular development project or property.The applicant shall
have the burden of demonstrating that a particular improvement qualifies for credit under
subsection(3)(b)of this section.
IN When the construction of a qualified public improvement gives rise to a credit amount
greater than the improvement fee that would otherwise be levied against the project receiving
development approval,the excess credit may be applied against improvement fees that accrue
in subsequent phases of the original development project.This subsection shall not prohibit a
unit of govenunent from providing a greater credit,or from establishing a system providing for
the transferability of credits,or from providing a credit for a capital improvement not identified
in the plan adopted pursuant to ORS 223.309,or from providing a share of the cost of such
improvement by other means,if a unit of government so chooses.
(c)Credits shall be used in the time specified in the ordinance but not later than 10 years from
the date the credit is given.
(5)Any unit of local government that proposes to adopt a system development charge shall
maintain a list of persons who have made a written request for notification prior to adoption or
amendment of a methodology for any system development charge.Written notice shall be
mailed to persons on the list at least 45 days prior to the first hearing to adopt or amend a
system development charge,and the methodology supporting the adoption or amendment
shall be available at least 30 days prior to the first hearing to adopt or amend.The failure of a
person on the list to receive a notice that was mailed shall not invalidate the action of the local
government.The unit of local government may periodically delete names from the list,but at
least 30 days prior to removing a name from the list must notify the person whose name is to be
deleted that a new written request for notification is required if the person wishes to remain on
the notification list.No legal action intended to contest the methodology used for calculating a
system development charge shall be filed after 60 days following adoption or modification of
the system development charge ordinance or resolution by the local government.A person shall
contest the methodology used for calculating a system development charge only as provided in
ORS 34.010 to 34.100,and not otherwise. [1989 c.449 s.4;1991 c.902 s.28;1993 c.804 s.20]

RE: City of Tigard Distribution System Hydraulic Study Financial Flan Technical
Assistance
Introduction
Ju accordance with your request and the City's authorization, this technical memorandum has
been prepared to document a cost apportionment of recommended water distribution system
improvements from the City of Tigard's recently completed Water Distribution System
Hydraulic Study. The methodology used for the apportionment of costs is developed and
applied in accordance with your direction. This methodology is used to apportion the project
cost of each improvement between existing and future capacity needs of the system and
Presents tabulated summaries of this effort.
Background
In May 2000,a Water Distribution System Hydraulic Study was completed for the City of
Tigard by Murray,Smith&Associates,Inc. As part of this study a detailed hydraulic
analysis of the distribution system was performed. The analysis evaluated the performance
Of the existing system and identified system improvements necessary to correct existing
deficiencies and to provide for future system expansion. Also included in this effort was the
development of project cost estimates for all recommended improvements. These estimates
are used in this memorandum as the basis for all cost data-
In
ataIn conjunction with the hydraulic study,the City is also reviewing and updating its water
service area system development charges(SDCs). In developing the SDCs,a methodology
was established in accordance with our discussions for determining the proportion of each
improvement needed to correct existing deficiencies and the proportion needed for system

expansion. In addition, all improvement project costs associated with the Bull Mountain
service area are identified. The Bull Mountain service area includes the 550-foot zone, the
713-foot zone and the 713-foot high pressure zone covering areas on Bull Mountain and
Canterbury Hill. Presented below is a description of the methodology developed to
apportion the costs of recommended improvements and to identify improvements needed to
serve the Bull Mountain service area-
Methodology
reaMethodology
Work associated with the hydraulic study included identification of existing population and
water demands, and development of anticipated ultimate population and water demands for
the entire water service area. Based on projected water demand data and planning and
analysis criteria developed for the hydraulic study,distribution system piping,pumping and
storage improvements needed to correct existing system deficiencies and to support system.
expansion were identified for the water system service area
For use in development of SDCs,recommended improvements are grouped according to the
pressure zone they will serve. The proportionate difference between the existing maximum
day water demand and the projected ultimate maximum day water demand for each pressure
zone is the basis for apportioning costs of improvements between existing capacities and
future capacity needs. Project costs for improvements recommended within the Urban
Deserve areas are considered entirely for future development and are apportioned as such.
Water demands and corresponding existing and future capacity percentages for each zone are
shown in Table 1.

Most improvements recommended in the hydraulic study will ultimately serve only one zone
and are easily divided by the capacity percentages for that zone. A few projects will serve
more than one zone when they are completed.. For these improvements,a more detailed
allocation calculation is required. A discussion of this allocation is presented below.

Pumping and Storage Facilities for the 713 foot Zones
The High Tor Reservoirs, and the pumping facilities serving them, supply both the 713-foot
zone and the 713-foot high pressure zone. Improvements reconunended to these pumping
and storage facilities are initially divided between the two zones based on their respective
ultimate maximum day water demand. The project cost of each recommended improvement
is then apportioned into existing and future costs using the method described above. Finally,
the existing and future costs from each zone are added back together as listed in Table 2.
Transfer Pump Station
The Transfer Pump Station will ultimately serve the 550-foot zone and both 713-foot zones_
Improvement costs for the transfer pump station are appropriated based on proportionate
ultimate pumping capacities to each zone. Under this condition, approximately 3,900 gpm
will be pumped to the 550-foot zone,and approximately 3,300 gpm will be pumped to both
of the 713-foot zones. The portion of the project cost allocated to the 550-foot zone is then
divided into existing and future costs using the previously described method. The portion
allocated jointly to the 713-foot zones is split between the two,and then divided into existing
and future costs. The existing and future costs from each zone are then added back together
as listed in Table 2.
Pump Station No.2
Pump Station No_2 will ultimately pump to the 10 MG Reservoir,which provides storage
for the entire water service area. The project cost allocation of this improvement serving the
Bull Mountain service area is determined by proportioning costs between the Bull Mountain
service area and the entire service area under a maximum day water demand condition at
saturation development. The project cost is then divided into existing and future costs using
the method described above. This improvement is listed separately on Tables 2 and 3 to
reflect the portions of its service to the 410-foot zone and to the Bull Mountain service area.
Conclusion
Cost breakdowns for all proposed facility and piping improvements are summarized in.
Tables 2 and 3. 'fable 2 lists improvements that will serve the Bull Mountain service area,
and Table 3 lists all other improvements-

■ New Council elected in West Linn—This will be a "no growth" council; they look at
the expansion of South Fork as a`growth tool.
■ Oregon City— Staff,and a couple council people, along with a couple of community
"movers and pushers" are against the concept of expanding South Fork. Mayor
Williams is still actively trying to gather support.
On January 11, 2001, the new councils of Oregon;City and West Linn will meet to
Pearn about South Fork. The second half of the meeting will be to decide if the two
newly elected wish to continue.to explore the opportunities for expansion:
■ At this point there are many questions and concerns by West Linn and Oregon City.
The.draft IGA that.was)discussed at the November South.Fork meeting (Paul ,Hunt
and"Mike Miller.attended) has been withdrawn from consideration..,
• If West Linn and Oregon City wish to continue exploring the expansion of South
Fork, an elected official's workshop will be held February 1, 2001, at West Linn City
Hail.
• Besides the anti-growth movement in West Linn, the three major concerns are:
1. Control — Should the two original members (Oregon City and West Linn) have
majority representation on the South Fork Board even when others, like Lake
Oswego and Tigard, may use more water and pay for more capacity?
2. Loss of Water Rights — Presently South Fork has plenty of water rights, in
fact, they have excess rights for their projected demand. Do they want others
to partner with them, possibly loose them to Water Resources or share with
others?
3.. Serving Tigard —Who is outside the Clackamas Basin?

Subject:: Summary of°Consoitium Board Meeting
Here is a brief summary of what happened Wednesday night. For the most part it was pretty uneventful.
Consortium Membership is now technically 23,members•with a quorum of 12 members due to a.couple of
mergers (TVWD-Sherwood, and the creation of S.unrise.Water Authority-Mt. Scott/Damascus/Happy
Valley). This will not change the amount of money that is collected in dues.
Executive Committee Proposal
Jim Duggan of TVWD and-Bruce Fontaine of CRW gave a presentation on the proposal for creating a
Consortium.Executive Committee. Only a few agencies had any comment regarding this. The creation of
an Executive Committee°passed but no members were appointed.'This will.happen in March.
Consortium Work Program Concepts for FY 2001-2002
Greg DiLoreto presented an outline of the proposed budget which breaks down into 3 categories: 1);Base
Budget(which includes conservation)'$414,500-which.is:$3,300 less than this yeat, 2) Special:Two Year
Assessment-for revision of the RWSP $226,250 per,year for two years;and 3) Enhanced Level of
Service Regional Conservation Staffing $43,550 for next:year and $81,050 thereafter.
There was little or,no comment or feedback on the proposed budget. The only agencies that had
comments was the Board member from the City of Beaverton who supported the whole package deal,and
Rockwood. Rockwood's Board member, said that Rockwood would have a new Board at the beginning of
the year and'that they were looking to cut budgets not increase.them. There was discussion that a small
group of,Board members and Lorna might go and meet-with Rockwood's new Board.
Budget Carryover
Was approved.
Water Service Maintenance-Program
Bruce Fontaineof CRW told'the Board about:�a new Water Service:Line Maintenance program (which is
kind of like water line insurance)and about the possibilities of doing this as a regional program., The more
participants the better the costs. CRW staff will do,more research about the program and report back at
the next.meeting.
'Other Business
*,CRW's Washing..Machine rebate program has had 36 application -th;e,only budgeted for 50.
CRW and Rockwood announce their new partnership was"underway.

Portland Water Bureau Provides Advice On Reducing'Lead.AtThe Tap
While there is.no detectable lead in Portland's source water supply;some households may be
exposed to.lead in drinking water through_their plumbing. At partict lar:ii are'f omes which
were built before,.1986 with copper pipe and,lead solder. Oregon banned lead solder in 1985:,
Homes built,shortly before'the ban have the:.greatest possibiliiyof exposure'to lead in drinking

Twice a year, drinking water utilities testhigh-risk homes for lead levels. State and federal.
regulators have'developed specific education programs:for utilities-to share with all customers if

by the Portland Water Bureau and its wholesale providers, some high=risk homes exceeded these

"Even lea&free drinking water can interact plumbing.to leach lead into the water," said Water
Bureau Administrator,:Michael Rosenberger. "Leaching occurs from exposure overtime. To test
-lead exposure,we draw water samples which have been`standing'in the pipes for several hours.
The,good news,is that,consumers can reduce lead.exposure from plumbing by hmning'their water

"Our Bull Run water is soft,"acknowledged Rosenberger,"so we treat it to make it less
corrosive. Since hot water is more corrosive than cold,it is important,to use only coldwater.for -
cooking, drinking,and particularly when making baby formula or juice_."
"Frequent testing helps us better understand our customers' risks, and triggers important
education actions,"said Rosenberger."Ideally, all plumbing fixtures would be.lead,free,but they
aren7.t. So the next best option is to inform dour customers,and provide them with the,knowledge
to protect themselves and their families. The best protection is the simplest: clear the pipes of

Twelve months of water:quality monitoring of the Willamette River was conducted
near Wilsonville Oregon, from August, 1999 to July 2000. Thissarnpling program
is a continuation of ongoing' efforts to 'characterize the water quality of the:
Willamette River 'in the 'vicinity of a new raw water intake and water treatment
plant facility in the City of Wilsonville Oregon. Previous sampling includes a.
comprehensive program funded by Tualatin Valley Water District (TVWD) at this
location from April 1994-July 1996 and a program funded ,by `the City, of Tigard
'from July 1:998-July 1999.
The Willamette Water Supply Agency (WWSA) program maintains an ,emphasis
on understanding. the physical, chemical and biological parameters. that are of
interest for,water treatrn'ent and ipublic health. The program ;included regularly
scheduled- sampli rig for a variety of drinking wafer quality . parameters,
microbiological contaminants,' trace metals, inorganic chemicals and' an
exhaustive list of organic chemicals. The sampling program was designed to
encompass current and anticipated' federa6 and state monitoring requirements
under the Safe Drinking Water Act.. The program went. well beyond drinking
water regulatory, requirements in order to better' understand the water .quality
impacts of,man-made chemicals that are in use in the Willamette River.Basin.
• Overview of Sampling Program
Willamette River Waterwas collected, for'analysis at River Mile 39 in. Wilsonville,
Oregon. This site was previously, used for the. above mentioned sampling
programs in 1994-1996 and 1998-1999:
The monitoring program:included weekly and monthly sampling of oeheral' water
quality,-and. physical', parameters from August 5, 1999 through November 30,
1999.-Quarte' pies for an extensive list of organic chemicals were collected
in August and November 1999, and February and July. 2000. An additional
sample was collected in November; during the first major storm of the season, to
capture worse-case water quality conditions in the River.
=Results
The Willamette River is a soft, generally low turbidity source with a low naturally
occurring organic carbon content. General water quality, including, inorganic,
physical and microbiological parameters, was consistent with-previous sampling
results; and,with historical :values.
Water quality results were also considered in-the context of current or anticipated
drinking water regulations and previous studies. 'M'ajor findings include:
Willamette Water Supply Agency ES- i
Willamette River Raw Water Monitoring Program
Annual Report 1999-2000
• o Inorganic, and microbiological sampling results;were consistent with previous,
years' findings-. None of these parameters are outside' the range of
acceptability for water treatment.
o All currently 'regulated inorganic and radiological parameters in untreated
water were well below standards for treated water. Two regulated organic
chemicals were detected over five sampling events, out of 64 regulated
organic contaminants each quarter. The contaminants atrazine. and simazine
Were detected one time (i.e. there were no repeat detections), at levels at,or
less than 1 part per billion.
s One organic chemical. that is included on the EPA's Contaminant Candidate
List, as a priority for regulatory determination, was observed. Th'e compound,
metolachlor., was detected once at a level less than 1 part per billion.
♦ The USGS has identified pesticides detected in small,.streams throughout the
Willamette 'River Basin. 'Based on the results of this study, all pesticides that
had been detected anywhere in the Basin were included in -the WWSA
monitoring program. Two regulated pesticides atrazine and simazine (as
noted in the first bullet) were observed during the sampling period.
• ♦ The EPA has recently finalized the Unregulated Contaminant Monitoring ,
Rule, which updates monitoring requirements for currently unregulated
contaminants; ;including or chemicals. None of the -20 :unregulated
organic chemicals covered under this new Rule were detected.
♦ An additional suite of .180 organic chemicals, including pesticides; herbicides
and industrial-chemicals were ;analyzed as part of ,Montgomery Laboratories
Analytical packages. One organic chemical; di-n-butylphfhalate was detected
at 18 ppb. This chemical is a common laboratory contaminant; and is not a
candidate for regulation at this time.
Overall water quality results are consistent with previous studies. 'These results
indicate that the Willamette River continues to be, a soft,-generally low turbidity
source with a low naturally occurring organic carbon content.
'.'No contaminants were observed which_pose concerns about the ability of readily
available water treatment. processes to meet and surpass current and anticipated
drinking water standards. Detected organic chemicals were present in the raw
waterat levels well below- treated .drinking water stand'ards., Sngle.event
detection .of four organic chemicals were observed over the sample period, at
levels of -approximately one 'part per billion or less. Treatment processes will
reduce these levels even further.- Tastes and odors occur year-round in the
River, similar to previous results. This suggests the need for..treatment.

processes to control these aesthetic effects. The same processes which are
• used as barriers to organic chemicals in water; ozonation and granular activated
carbon filtration, are commonly used for the control of tastes odors.
Recommendations
♦ Water quality monitoring of the Willamette River should be continued. The
1.999/2000 water quality program results are consistent with results from the
two previous sampling programs, and are also. consistent with water quality
research conducted by the USGS on the mainstem of the Willamette River.
Continuation of the monitoring will develop information on the consistency of
water quality in the River and add to the historic period of record.
Water quality monitoringshould continue to emphasize sampling during low
flow and high flow conditions. Ongoing monitoring will add to an;
understanding of winter4imb water quality variations due to precipitation and,
river flow. This information can be useful for the refinement of water
treatment plant design criteria.
o The list of organic chemicals selected for monitoring should continue to be
updated and refined. New analytical methods are continually being
developed and new analytes should be added as these methods are
developed. . New and anticipated regulations should be reviewed and
• analytes added -where needed. Reports and studies by other agencies and
groups should - be reviewed as available, and. analytes added to the
monitoring list as,appropriate..

Twelve months of water quality . monitoringof the, Willamette River near
Wilsonville Oregon, from August 1999 to July 2000. This program is a.
continuation of ongoingi'efforts to characterize the water,quality of the. Willamette
River in the Vicinity of a potential future municipal water supply diversion.
The 1999-00 year was drier than average, and was significantly, drier than' the
previous sampling year, in 1998-1999. Daily observed precipitation was
especially low for the sampling period, with measurements below historic values.
Low flow:and high flow conditions were observed, thus capturing as representative
picture of the river throughout the year. ,. A large' storm, event in November,
satisfied 'the objective of sampling during "worst-case" water quality conditions
With respect`to water treatment.
Conclusions:
General water quality parameters including inorganic, physical and
microbiological_ parameters were -consistent with previous years' sampling
results, and with Historical values.
'Water quality results were. also 'considered in the context of current.or anticipated
