Administrator's Report
1. Resolution to approve minutes of last meeting, as written.
2. Resolution to pay vouchers.
3. Visitors.
Mr. Dean Alexander, 15700 S. W. Bull Mountain Road, will
appear before the Board to request relief on a high water bill.
For the period September 25th to November 25th his bill was
$86.50 due to a leak on his side of the meter. (on his property).
His normal bill is $9.70 for this same period.
I do not have much sympathy for Mr. Alexander. He is one
of those habitual offenders who never pays the first 2-month
bill received, but always waits for the 4-month billing.
During the past 1 years he has been delinquent on all occasions.
(See attached ledger card). This causes considerably more
administrative problems.
4. Other business.
5. Delinquent water bills.
Several of you have noted the large sums outstanding each
month due to delinquent water bills. As the number of meter
connections continues to grow, the problem compounds itself.
For many years the TWD has been very lenient in allowing cus-
tomers to pay within 15 days after the second billing (4-month
bill). This is 2i months after the first billing. Many customers
are taking advantage of the district by completely ignoring the
first bill, knowing full well that the water will not be turned
off until after the second billing.

Administrator's Report (Continued)
Section 11 of the Rules and Regulations states, "all bills
are due on the 10th day of the calendar month following billing.
unpaid bills become delinquent after the 12th
of the month".
A change in the rules is not required, but it would be
preferable to demand payment within 14 months of the initial
billing. This would eliminate double bills of 4-month periods
and the cumulative resultant high water bills. Most utilities
and creditors demand payment by the 10th of the next month or
within 30 days so this change will not be a hardship on anyone.
Normally, a 30 day time limit would be desirable, but, in this
case, delinquent accounts from the prior month would interfere
with the billing of the second set.
The water bill should be the first to be paid by a customer
because it is the best bargain. All one need do is compare his
2-month water bill versus the monthly bills from PGE, Northwest
Natural Gas, General Telephone, etc.
'4lnr
A resolution is not required, but your concurrence is pre-
ferred and it should be publicized in the newspaper. This change
should be effective for the billing of December 20th and remit-
tances due by February 10th.
6. Election. 1975.
May 6th, Tuesday, has been designated as the election date
for commissioners of water districts. Position #5, John Schwartz,
is the only office open for election to a 4-year term. His elec-
tion last year was for 1-year, completing an unfinished term of a
former commissioner. (Resolution enclosed)
If a bond issue is proposed, approval of the voters should be
obtained during a regular election day and not a special election.
Thus, it is recommended that, if a bond issue is to be considered,
it be approved for May 1976 on the regular primary election date.

Administrator's Report (Continued)
This will provide the staff the necessary time to explore
in detail the requirements for capital improvements of the dis-
trict. By that date, Washington County will have decided whether
to form a county water service district. As Don Thomas noted,
if the county gets into the wholesale water business and adopts
the ST&R plan of obtaining water from the Willamette River, they
will be required to construct a 20-million gallon reservoir on
Bull Mountain; thus, saving the TWD this expense. It appears
that the district's best policy at this time is to "wait and see".
7. Eastern Washington County Water Purveyors Council.
The City Manager of Beaverton called a meeting on December
19th to discuss water supply for eastern Washington County.
Absolutely nothing was accomplished. -- A waste of time. I
believe Clarence Nicoli has the best idea. Let's wait for
Washington County to act before initiating a new concept. At
the present time, Washington County is awaiting the Bartle-Wells
financial report on ST&R's proposal on capital improvements for
the Portland Bureau of Water Works.
8. Reservoir at S. W. 125th and Gaarde Street.
Although it is best to delay a decision on a new reservoir
the staff will continue to investigate and make plans for the
reservoir to be constructed at the terminal reservoir site.
Enclosed is a soils and foundation study prepared by Northwest
Testing Laboratories.
Our initial concept was to build two 5-million gallon tanks
on this tract of land, the first to be constructed during 1976-77.
The investigative report indicates that the soil conditions may
present some major problems with two tanks where blasting will be
required. Accordingly, we are exploring the possibility of con-
structing only one large tank. The width of the lot is only 220
feet which causes some problems in sizing the reservoir. The
property owner to the north does not desire to sell any land and
Benny Larson cannot afford to sell anymore of his land.

Administrator's Report (Continued)
The following chart shows the diameters and costs for various
concrete sub-surface reservoirs:
Size Diameter Cost Cost per Gallon
5 MG 156 feet $ 457,000 9.10
6 MG 170 feet $ 525,000 8.70
8 MG 197 feet $ 657,000 8.20
10 MG 221 feet $ 787,000 7.80
It may be advantages to construct one 8 MG tank in lieu of
two 5 MG tanks. The outside diameter of an 8 MG reservoir is
about 200 feet. This would require a variance from Washington
County to construct the reservoir within 5 feet of the side
property lines. It would also be necessary to obtain temporary
construction easements from adjacent property owners during the
excavation period.
9. EmPlovee's retirement booklet.
Enclosed is the final draft, hopefully, of the employee's
retirement booklet. It took a lot of research, but I believe we
have a booklet worth publishing.

Re: Soils and Foundation Investigation
Proposed Subsurface Reservoir
Tigard, Oregon
Gentlemen:
At yoor request we have conducted a soils and foundation investigation at the site of the
proposed subsurface reservoir to be located west of Tigard, Oregon. We present herewith a report
of our findings, conclusions and recommendations.
krre Site Description
The site is located on S. W. 125th Avenue immediately west of Tigard, Oregon. The east
half of the 3.18 acre tract slopes gently to the east and has several fruit and nut trees. The west
half of the property is heavily forested and slopes rapidly to the west. Our reconnaissance within
and surrounding the proposed building area did not encounter evidence of unstable slopes.
Subsurface Exploration
Power auger borings to depths ranging from 11 ft to 21 ft were made at five locations, as shown
on Fig. 1 . Samples were taken with Standard Penetration Tests at 2.5 ft intervals to 15 ft, and at
5 ft intervals thereafter. The Standard Penetration Test is performed by driving a 2- in, O.D . split'
spoon sampler into the. undisturbed formation at the bottom of the baring with repeated blows of U
140-1b pin-guided hammer falling 30--in. The number of blows required to drive the sampler a given
distance is a measure of the soil consistency. Samples were identified in the field, placed in sealed
containers and transported to the laboratory for further classification and testing.

Tigard Water District Soils and Foundation Investigation
Laboratory Tests
Laboratory tests were performed on representative samples. These included natural water con-
tent, Atterberg Limits and particle size distribution. Results of tests are summarized in Table I,
attached.
Soil Conditions
Soils underlying the site include an upper unit of silt overlying a layer of silty clay which rests
on weathered Columbia River basalt.
Soil units penetrated in borings are described briefly as follows:
1 . An upper layer of moderately firm to firm, brown silt and clayey
silt ranging in depth from 6 ft to 12 ft.
2. An underlying unit of moderately firm to firm, brown, silty clay.
It was encountered only at the east and west ends of the property
and ranges in thickness from 4 ft to 9 ft.
3. The lowermost unit consists of weathered basalt mixed with residual
silt and sand. It was encountered in all borings.
Logs of borings have been combined with topographic information to construct a geologic section
through the site; this appears in Fig. 2.
Groundwater
Groundwater was not encountered in any of the borings. The regional groan-'water table is
approximately 275 ft below the site. •

Tigard Water District Soils and Foundation Investigation
Proposed Plans for Construction
The present plans call for the construction of two concrete reservoirs. The west tank is to be
constructed soon, and the east tank, at a later date. The design calls for the tanks to be buried
with the floor elevation at approximately Elev. 435. (30 to 35 ft below present grade).
Conclusions and Recommendations
We draw the following principal conclusions and recommendations from our investigation at this
site:
1 . [he weathered basalt is very competent and can he. used as the
supporting horizon. Footings placed in the weathered basalt
can be designed for contact pressures of up to 15,000 p.s.f.
2. We anticipate that some blasting will be required in making the
excavation in the weathered basalt.
3. Construction plans indicate that the west extremity of the west
reservoir will extend beyond the weathered basalt at the proposed
footing elevation. If the major portion of the tank is to be
founded on the weathered bedrock the west extremity should
be founded on bedrock also. This could best be achieved by
either relocating the structure (if space will permit) or extending
the foundation wall to the bearing horizon.
