Gentlemen:
Subject% Springbrook Water Source
During a 3 June 1975 meeting in Mr. Houghton's office, he
requested a fee estimate for the superficial geohydrologic
investigation proposed in our 14 May 1975 letter.
We propose that we do the work on a time plus expenses
basis. Our charges would be based on time spent at the
project at oc - normal rates. These rates are listed in our
1 May 1975 letter to Mr. Warren C. Gonnason (Engineering
Services for Miscellaneous Consulting) . Most of the proposed
work would be performed by an EN3 project manager at $200
per day. Other costs such as mileage at $0.15 per mile
would be charged directly. We estimate the total fee to be
$1,800 to $2,000.
If you are in agreement with this pr,)posal, we would appreciate
a letter of authorization for billing reference.
Sincerely,

RENTON, WASHINGTON
' INTRODUCTION
1 This report presents the results of oar surficial geologic
reconnaissance and subsurface explorations at Springbrook
' Springs Municipal Water Supply, Renton, Washington. The
purpose of this investigation was to determine:
' 1. The local geology and geologic structure of this
area as related to the groundwater flow system
and the occurrence of springs,
2. The feasibility of developing additional springs
In the area,
3. The extent of leakage around or through the upper
1 dam and provide recommendations on the repair or
reconstruction of this dam to reduce the leakage.
' 4. The utility of the lower dam as related to further
spring development and/or flood control.
This scope of work was accomplished by a field exploration
' program consisting of an initial site reconnaissance, geologic
mapPldg, excavations of four test pits at the front of the
upper dam, and drilling of six borings from 12.5 feet to 44.0
feet in and around the upper dam and collection gallery, and
flow measurements from mapped springs.
RecMmendatlons for the repair or possible reconstruct:on of
' the upper dam are based on engineering studies consisting, of
flow net analyses to estimate leakage under ind through the
dam and an estimate of costs for alternate mn?thods of p'assLble
repair.
' 2 • •
Additional spring development was studied by locating and
mapping the sources of sprin,;s in the area anc' estimating
the flows. In addition consideration was give, to the pos-
sibility of using the lower dam for additional spring
development or for flood control.
' STUDY AREA
Site Description
t
Springbrook Springs, located about four miles from the City
' of Renton, is in a heavily vegetated canyon trending south-
east opening into the Duwamish Valley. The watershed area
is dissected by two perennial streams that derive water from
springs at elevations between 190 feet and 240 feet above sea
level. Active since 1909. only the spring waters at approxi-
mate elevation '96 are collected behind a wooden and concret.-
dam and flow by gravity to Talbot Reservoir. The water is
tclear. cold and of good quality and represents a low cost,
low maintenance water supply for the City of Renton.
Geology
tThe soil types present at the study area were laid down during
the last glaciation. The final advance of the Puget Lobe of
tthe continental glacier occurred about 14,000 years ago in
the Renton area. As the glacier approached the area, a broad
meltwater outwash plain was covered with gravels, sands and
silts. This material is referred to collectively as Advance
Gravels. The glacier then over-rode these materials and
deposited a dense compacted layer of till. The retreat of
' the glacier was marked by the deposition of more water-laid
outwash deposits called Recessional Gravels, This cyclical
process has formed a succession of complex glacial deposits
as encountered in wells near the study area.
' The deposits present at the study area have been interpreted
as Recessional Gravels (Luzier, 1969) although they may include
' some Advance Gravels. The difficulty in distinguishing between
these units is great if their relationship to the till cannot
' be established. No such relationship was found even though
the till is present, underlying the upland immediately adja-
cent to the study area.
' The Geologic Map presented in Figure 1 is based on photo
' interpretation and field mapping accomplished durlir late
July. The inferred contact between the till and gravels
was mapped south of the area on the basis of air photos,
but whether the gravels are stratigraphically above or
below the till is not apparent. The Recessional Gravels
mapped appear to underlie the entire Springbrook Springs
area. Although they are referred to as gravels, they also
tinclude sand, silts and clays deposited in lower energy
conditions. The gravels are generally poorly sorted with
some well sorted beds. The sands occur as interbeds in
the gravel and often become the dominant type as seen in
the old borrow area north of the spring site. The silts
and clays occur as common thin interbeds within the sand
' and gravels. A single 10 to 12 foot clayey silt bed like
that seen immediately above the upper collection gallery
has been mapped at several locations in the area (see
' Geologic Map, Figure 1). These fine-grained beds range
from a rusty clayey silt to a gray, silty clay. Materials
' similar to those surface exposures at the springs were
encountered In the borings, with sandy gravel and sand
' predominating.
The attitude of the beds ranges from horizontal to a 12" dip,
striking from northeast to northwe.+t. These non-horizontal
attitudes are interpreted as foresee bedding in a deltaic
tstructure and are local only,
4 ` •
Glacial till has been mapped mantling much of the upland
east of the Springbrook Springs area (1.uzier, 1969).
' Characteristically it is a cimbination of densely compacted
silt, sand and gravel which possesses low permeability. In
' the study area weathered glacial till probably occurs south
of the springs as indicated on the Geologic Map, Figure 1 .
' Subsurface Conditions: Upper Dam Collection Gallery
In the immediate area of the upper dam and collection
gallery four test pits and six borings, located in the
tSit,. and Exploration Plan, Figure 2 were accompl+shed to
disclose subsurface conditions. All field operations were
monitored by a geologist from our firm. During the excava-
tion of the test pits and drilling of the borings he
' obtained samples and prepared descriptive field logs.
The samples were returned to our laboratory for further
classification. Each boring log and test pit log is
graphically presented in Appendix A, Figures A-2 through A-7
and Figures A-S through A-11, respectively. In addition.
' grain size analyses on representative samples taken during
drilling are, presented in Figures A-12 through A•15. A
brief explanation of these field operations and procedures
is Included in App:udi.x B.
tTest Pits TP-2. TP-3 and TP-4 along the front of the dam
encountered 4 feet to 5 feet of slightly silty, gravelly.
' fine sand with pockets of sandy gravel to a bottom depth
of 8 feet to to feet. Test pit TP-1 disclosed about v
feet of sandy gravel underlain by slightly clayey silt with
gravel to a depth of 11 feet. This lower unit did not
' appear continuous in the bottom of the test pit. Observation
wells were installed in all the test pits to monitor grotnd-
' water levels.
Tht borings along the front of the upper dam all disclosed
' similar sequences of material as shown in toe. Geologic Cross-
Scation A A' , Figure 3. Generally borings B-1, B-2, B-4,

B-5 and B-6 encountered between 8 feet to 13 feet of slightly
silty sandy gravel and/or undifferentiated organic silts and
' sands underlain by 15 feet to 20 feet of saturated sandy
gravel to gravelly sand to a depth of about 28 feet. The
saturated sandy gravel is underlain by saturated silty fiae sand
which was drilled to a maximum depth of 49 feet in boring
' B-6. Boring B-3 drilled in the collection gallery, encountered
about 5 feet of silt and clay slide debris covering t foot
of pea gravel previously placed by the City of Renton crews.
Under the pea gravel about 20 feet of saturated sandy gravel
to gravelly sand was disclosed underlain at 32 feet by sat-
turated silty fine sand. Boring B- 3 was sealed with concrete to
prevent leakage out of the collection gallery Observation
' wells were installed to the bottom of borings B-5 and B-6 to
monitor groundwater levels. Geologic Ctnss-Sections C B' ,
' B B' and A B' , Figure 4, present subsurface conditions across
The collection gallery dam, as disclosed by the borings.
Fhese cross sections are used later in the report to evaluate
' the groundwater flow system in thv Immediate area of the
collection gallery.
' Groundwater was encountered in all the zest pits from 5 feet
to 7 feet below the ground surfar . in borings B-5 at 7 feet,
and in B-6 at approximately It feet below the ground surface.
Groundwater
' A regional grcundwater study was completed by J. E. furier
in 1969 which described the geology And groundwater resources
of Southwestern King County. In his report he discussed
groundwater movement throughout Southwestern King County and
briefly described recharge sources of the area.
t
6 • 0
1 From Figure 5 presented by Lazier (1969) groundwater levels
are used to interpret groundwater movement. In the area of
Springbrook Springs groundwater flows down gradient from the
east near Youngs Lake towards the Duwamish Valley. Where
' the piezometric surface is projected higher than the surrounding
land surface groundwater could appear as springs or seepage
where permeable material outcrops along the valley walls.
Such is the case at Springorook Springs. The natural
groundwater gradient into the valley is intercepted by the
' small eroded canyon at Springbrook causing the occurrence
of springs in this area.
Recharge to the groundwater is from Incident rainfall and
' snowfall on the upland plain east and southeast of Springbrook.
Groundwater response to recharge by incident precipitation
usually corresponds to seasonal precipitation fluctuations.
However, the flows at Springbrook Springs are signiflcanlly
higher daring the summer months but probably . fleet the
' tag associated with recharge restricted by relatively imper-
meable deposits thot overlie the permeable Recessional
Gravels at rpringbrook Springs,.
' AC Springbrook the springs that emerge from the sides of the
main canyon and the canyon immediately to the north occur at
' elevations between 190 feet .And 215 feet except for the
springs southeast of tht collection gallery where they appear
at an elevation of about 235 feet (Figure 1) . in all cases
observed, the location of a spring is determined locally by
the occurrence of silt and/or clay beds with the water
emerging through an interval of sands and gravels immediately
above the silt or clay. Those springs napped below the lower
' dam appear to flow from the contact between the Recessional
Gravels and an underlying dense. silt), fine sand. This silty
' flne sand unit may be continuous with the silty fine sand
unit encountered in the borings.
1 7
These partially impermeable beds of clay, silt and silty fine
sand within the sands and gravels restrict the vertical move-
ment of groundwater. The clayey silt bed visible in the
bank above the reservoir is just one of these as is the clay
layer mapped in the northern canyon. By restricting the
vertical flow of groundwater these beds protect underlying
aquifers from potentially contaminated surface water.
' Cross-secttons CB', BB' and A'B' . Figure 4 help to illustrate the
groundwater flow system at the upper collection gallery.
Apparently the groundwater surface, breeched by the
' local topography at Springbrook, developed springs in
this particular area. (Note that groundwater is evid( nc
' below the gallery to a depth of at least 49 feet.) The
Initial wooden dam and subsequent concrete additions to
the dam served to back up groundwater seepage (springs)
In a reservoir to flow by gravity through pipes to the
Talbot Reservoir.

RECOWIENDAPIONS
' Feasibilit of Addltionnl Spring Development
Because of the abundance of groundwater seepages in the can-
yon north of Springbrook an,! at Springbrook (see Geologic
Map), the feasibility of developing additional water supplies
from this area was studied. Our primary concern involved
determining the total quantity of water which putentially
could be developed. From field measurements taken at each
' spring or at the confluence of seepages from two or more
springs a total quantity of spring water was estimated. For
the canyon below Springbrook four separate spring measure-
ments were made totaling approximately 125.000 gallons per
t day (gpd) or about 90 gallons per minute lglx»). Considering
this small quantity of water, the potential costs of constructing
more collection galleries plus costs associated with pumping
g . •
' this water because these lower seepages do not have the elevation
addi-advantage realized at the upper dam, we do not recommend
tional spring development below Springbrook Springs.
' In the canyon north of Springbrook a total of approximately
250,000 gpd (160 gpm) was measured. However, these springs
appeared to be issuing from above a clayey silt layer
' (similar to that observed above the upper dam) and there-
fore represent near-surface unconfined groundwater. Potentially
' this water could be contaminated by surface runoff and/or
septic system effluent from residences near to the Springbrook
t watershed. Considerations for development of these springs
should include treatment facilities to maintain drinking
' water standards. This fact alone could make spring develop-
ment in the north canyon unfeasible.
' Leakage at the Upper Dam
' Before investigating the methods for repair or reconstruction
work at the upper dam flow-net analyses were performed to
' estimate water quantities leaking past the structure. These
values could be used to compare particular repair or
' reconstruction methods and associated costs against the
potential increase in flows due to this work. A flow-net
represents the flow of water through an incompressible
soil and conforms to C -cy's Law. The water flows through
th- soil from an area of higher total energy or head of
' water to an area of lower total energy or head of water along
flow lines. The flow lines represent the route of seepage,
' in our case under the dam. In Figure 6.7S is a flow line,
0 is an equipotential or equal energy line. Along M the
' waLer his the same potential or energy. To compute the
seepage under the dam this equation can be used.

tFigures 6, 7 and 8 show three different flow-net configura-
tions that could exist at the upper dam. Figur3 6 represents
' the existing upper dam with an assumed depth of about 13
feet. Using the equation described above the computed
seepage value under the dam as illustrated is approximately
t 485,000 gpd or 338 gpm.
tFigure 7 is our representation of the flow under the upper
dam if extensive leakage was occurring between the wooden
dam and the concrete extensions to the dam. if the front
100 feet if dam was leak;ng, approximately 162,000 gpd or
1 1139pm are escaping through the existing structure. Note
that some of this leakage probably is intercepted by a small
auxiliary dam just northwest of the upper dam. Currently
' the auxiliary dam contributes water to the main supply by
an 8 inch steel pipe. There is also an overflow pipe from
' the dam which flows at an undetermined rate. We recommend
that the flows from this smaller dam be measured and examined
in light of our seepage values to refine the following pro-
jected quantity increases. The measured quantities from
the smaller dam necessarily were incorporated into our
projected values and therefore probably would decrease
these values.
' Figure 8 represents the flow under a dam which is about 15
' feet deeper than the existing structure. The calculated
value for flow under this is about 162,000 gpd or 113 &pal.
All of t;,e calculated quantities presented above assume an
average permeability for the sandy gravel of 0.2 foot per
t minute which we feel is representative of the material. These
flow quantities were used to study the feasibility of repair
or reconstruction of the existing upper dam.
' Repair or Reconstruction of Existing Dam
' Briefly, by repairing the existing dam, i.e. stopping any
leakage along a 100 foot sectioi of the dam between the
' wooden and concrete extension a.a approximate increase of
162 ,000 gpd or 113 gpm could be realized from the springs.
' By constructing a cutoff wall to a depth of about 15 feet
below the existing dam a total approximate increase of 465,000
gpd or 338 gpm could be realized from the springs.
' However, if such construction was completed it would be
appropriate to extend the cutoff wall to the less perme-
able very dense, silty fine sand, and as such the above
quantity of increase is considered conservative.
1 The costs associated with repairing or reconstructing the
' upper dam vary with the methods used. For both repair and
reconstruction a cutoff wall cc silting of augereast piles
appears to be the most effective and economical method to
accomplish each purpose. However, other methods such as
slurry trenches have been used for constructing concrete
' cutoff walls and could be considered for this project.
' The cost of constructing a cutoff wall of auger-cast piles
Is dependent on (1) the depth of pile, and (2) the relative
' density of the materials to be drilled for the pile. Because
the operation is complex involving heavy equipment much of
the cost is in the mobilization and set up of the machinery.
This fact would increase the unit cist of repair work in
relation to construction of a total cutoff wall. Based
ton conversations with various contractors we estimate that
for a short wall of auge. at piles (15-feet from existing
' grade) for repair work, the total cost could range from
about $11000 to $18,000, For a deep cutoff wall of auger-
cast piles extending to the less permeable silty fine sand, the
cost is exi:,�cted to range from $24,000 to $30,000.
t
' 11 . •
An alternative to augercast piles could be a slurry trench,
enabling a concrete cutoff wall to be poured abutting and
below the level of the existing dam, or a chemical or
cement grout current wall . A slurry trench operation also
is complex and mobilization of equipment for a project of
this size would not appear to be warranted. A grout cur-
rent may be economically feasible out a cost estimate has
not been attained due to possible requirements of secondary
and even tertiary grouting to provide an ef 'cctive cutoff
' wall.
Coats for repair or reconstruction must be viewed U
relation to potential benefits of increased water quantities
' from Springbrook Springs. For the repair work. I .e. a
short augercast cutoff wall a possible gain of I62,000 gpd
' could be realized at a cost of approximately 511,000 to
$18,000. For reconstruction work involein, n . xtLu> i\t
cutoff wall of augercast piles a possible iner(ast „t
' 485,000 gpd could be realized at a cost of apprexinmt, ly
5249000 to $3c,0(m. Note that the water quantities are
' subject to reevaluatl„n as described above- based on measure-
ments from the auxiliary dam northwcet of the upper collrc -
Lion dam.
Although the Initial cash outlay for the construc,.ion
' described above appears large the fact that Springbrook Is
a natural gravity flow system requiring little nwintenance
tenhances its existence as a municiplc water apply source.
tImmediate Work to be Accomplished at Springbrook
We reconmiend that the 4 feet to b feet of silt and clav slidt
debris be excavated from the cnllection gallery and be rcplo ,d
with 4 feet to 5 feet of on-site s.ndy Gravels. This would
' provide a larger volume In the ccl'ectinn gallery for water
' 12 . •
s'oragv. The sandy gravel layer should be covered with a
relatively impervious soil blanket and planted or covered with
an impermeable liner thus eliminating potentially contaminated
surface runoff from entering the gallery.
' Comment
During our field explorations at the upper dam we determined
that leakage war occurring between TP-i and TP-2 along the
' front of the dam. Whether the leakage was due to deteriora-
tion of the underlying wooden dam (as we suspect) or seepage
t under the dam was not discovered. Therefore, the feasibility
of repair or reconstruction work was considered. Those
methods presented appear to be the most efficient and cost
conservative. However, we also feel that the leakage could
be studied further by backhoe excavations at the front of
' the dam. If the leakage was concentrated in a small area
local repairs might improve flows from the collection gallery.
' Utility of Lower Dam
The lower dam at Springbrook appears to be stable in its
' present condition and could be used as a water holding
facility. TLere are two principle functions for which the
dam and holding pond could be used (, ) enlarged collection
tarea for spring water and (2) flood protection from surface
runoff.
Because there does not appear to he a sufficient amount of
' water to be gained f-om additional spring development an
enlarged collection system in our opinion is not needed.
tThe lower dam has already exhibited a use in flood protec-
tton. and we feel it should be maintained as a flood
' protection facility. In providing protection from �loodirig
a certain regulated water level could be maintained in .he
' ponding area offering ar aesthetic as well as useful purpose
for the lower dam.

If any questions arise during the review of these studies
and subsequent recommendations we would be pleased to discuss
tthem at your convenience.

The field exploration program consisted of six borings and
four test pits located as shown in the Site and Exploration

' Tic bnrings were drilled to depths of -i4 feet in order to
give a representative evaluation of subsurface conditions
' within the upper dam area. The borings were drilled using
a truck-mounted, continuous-flight, hollow-stem auger drill

by Mr, pot Spencer, a geologist from our office, who prepared
a detailed Inq of oath boring and obtained representative
samples in air-Light containers of each soli type encountered

CITY OF RENTON

CH2M HILL, Inc.
Seattle, Washington
Record No. 59336.0 Copy No. ., _
WATER SUPPLY DEVELOPMENT AT SPRINGBROOK SOURCE
GENERAL
The work reported herein resulted from the recommendation
by CH2M in a July 1968 report on horizontal drillino at
Springbrook.
AUTHORIZATION
By acceptance of our letter proposal, dated 6 September 1975,
the City authorized engine=ring services in connection with
drilling a well at Springbrook.
PURPOSE
The purposes of this report include:
o Record the history of drilling by H. O. Meyer
Drilling Company, Kirkland, Washington.
o Report upon the well construction and testing.
o Discuss tie potential of the well for production.
o Make recommendations.
DRILLING AND CONSTRUCTION
Figure 1 shows the construction log of the 268-foot-
deep well. Four sizes of casing and a 50-foot PVC well
screen were the major installed components. Figure 2 is a
geologic log of the well.
A 20-inch casing was driven until a clay layer was
encountered that would act as a seal between any upper and
lower water-bearing strata. The clay was found a- 44 feet
and the casing was driven into it for 8 feet.
A 12-inch casing was driven to 105 feet where it could
no longer be advanced due to lateral pressure from the pene-
trated strata. Eight-inch casing was then driven until it
became immovable at 195 feet. Six-inch casing was therefore
installed and driven to the bottom of the well at 268 feet.
The geologic log shows the material encountered and the
water-bearing strata. In summary, the material is glacial
in origin and consists of alternating sands, gravels, and
clay. Bed thickness varies from a few feet to 30 feet. The
aquifer, which was eventually pump tested comprised gravels
and alternate fine, medium, and coarse sands.
Water-bearing strata were encountered at several depths
as noted on figure 2. However, bail tests performed at
those depths indicated that only small quantities of water
existed above 220 feet. At this depth the water level rose
in the casing from the drilling level to 74 feet. A bail
test indicated sufficient water present to recommend a pump
test, but it was decided to continue drilling until the
aquifer had been fully penetrated. Water samples were taken
and tested for quality. The data is discussed later in the
report. At 267 feet, the bottom of the aquifer was reached
and drilling ended after several feet of open hole had been
drilled into the underlying impermeable aquaclude. Fifty
feet of 6-inch telescoping PVC well screen was installed
with a lead packer and the 6-inch casing pulled back to
expose the screen.
PUMPING TEST
A nominal 250 pounds per square inch (psi) capacity
compresr r with 268 feet of airline was installed in the
well ar .. used to develop the surrounding aquifer by horizontal
jetting. Development was continued for 10 hours with about
1-3 cubic yards of sand being brought out of the well.
The well was first test pumped during the afternoon of
19 March 1975 a� a trial run to check the equipment. From
static water level of 74 feet, the drawdown came near the
end of the airline when pumping at 260 gallons per minute
(gpm) . It was concluded that test pumping should start at
200 gpm.
An extended pumping test, lasting 7 hours and 13 minutes,
was run on 20 March 1975. The field data are given in
tables 1 and 2 and are plotted on figures 3 and 4. Very
little sand was pumped during the test, indicating adequate
prior development of the aquifer.
WATER QUALITY
After 2 hours of pumping, a water sample in a sterilized
bottle was taken for quality analysis. The results are
given in table 4. The reason for the difference between the
two sets of analyses can be attributed to the nonsterilized
sample bottles used in the first collection.
Analysis indicated that water quality of the well would
be acceptable for domestic use.
CONCLUSIONS AND RECOMMENDATIONS
The tes': data indicates a specific capacity of 2 gpm
per font of drawdown at 200 gpm over less than 6 hours and
without definite stabilization at 106 feet drawdown.
The City can obtain more than 200 gpm by drilling
additional wells in the Cedar River alluvial fan near City
well. In order to justify the cost of a productt n well at
Springbrook, a capacity of about 1,000 gpm at a high pumping
level would be required. in our opinion the sustained
specific capacity of a well of this size properly constructed
with gravel pack and well screen would not be obtainable in
the aquifer presently encountered.
The possibility of exploring for water at depths below
268 feet has been considered. Examination of all available
local data and discussion with Robinson and Noble, ground
water geologists familiar with the local area and the Rentc-r
Cedar River Well No. 8, has produced no optimism that an
adequate production well can be obtained at Springbrook.
Farther drilling is not recommended.
MEETING AT CITY HALL 7 APRIL 1975
A meeting was hold at City Hall on 7 April. 1975 to
discuss the Springbrook well. The recommendation was made
by C112M HILL not to continue drilling but to request H. 0.
Meyer Drilling Company to salvage casings and screen to the
extent possible and abandon the well in accordance with
State requirements.
This report is being submitted before the above steps
have been completed.
It is recommended that photographs taken by the :ity be
attached to at least one copy o£ this report and thst a site
sketch be included to record the position of the abandoned
hole.

'ransmitted herewith is a brief report to place on record the work at
Springorook for developing additional water supply by horizontal boring.
ti
In our opinion further e.ye .diture is not ;ustified until the possi- 4.
bility of obtaining the desired volume of water from a vertical well is
exoloreo. We therefore recommend tfiat experienced drillers be invited to "
su6nit competitive bids for vertical drilling. Further measures should be
taken to guard against contamination of the supply from the recent construc-
tion shown on Plate 2. -

WATER RIGiTS
^era has been some question in the past regarding the validity of the
City's rster rights at Springbrook and, with the proposal to develop additional
suppl: at Springbrook, a meeting was held on 15 November 1966 attended by Mr.
Jack ;:ilson, Cit., Engineer; Mr. dilliam R. Smith, geologist, State Department
of Water 4esoerces; Mr. Ralph Anderson, Department of Fisheries; and Mr. Barry
Barnes, Cn2M. After a general discussion, in the office, the site was visited
and the existing facilities examined.
-'.e Department of Fisheries had an interest due to the salmon spawning
whin takes place in the flat area down by the State highway and water comes
fror tr:e two creeks at Springbrook. The findings of the Department of
Cor.Servation under cover of letter dated 30 December 1966 are reproduced and
bound in this report. The report of the Departments of Fisheries and Game
is also included. The only certificate applying to Springorook is No. 463,
the others listed relate to existing or abandoned wells elsewhere in the City.
The writers commented on the report of the Division, of Water Resources by letter
dated 14 January 1967, which together with an extract from the G;2M study of
October 1965, is bound with this report. The Current status at Springbrook
(July 1966) is that the permit for construction was extended in April 1966 to
1 January 1969 under Application No. 19590,
REZONE REQUEST,SPRINGMK AREA
Also bound in this report for the record is correspondence relating to
a rezone request for an area adjacent to Springbrook which involved excavation
and possible disturbance of the water supply available to the City from this source.
PROPOSCJ DEVELOPMENT AT SPRINGBROOK
Enclosed with this report is a letter dated 25 April 1967 to the rity
Engineer which describes the proposed method of developing additional water
fron the Springbrook source. It will be seen that the possibilities were
horizortal drilling at the present collection facility, horizontal drilling
below that facility, and vertical drilling in the area. At the time of writing
this current report, horizontal drilling At the infiltration facility is the
IU Only step which has been accomplished. Photographs of equipment used appear
in Plate 1.
-I-
i
The considerations involved in driiling horizontally include^ the
possibility that the alternate pervious and impervious strata dipped into the
hillside or away from the infiltration facility. Tne possibility of large
boulders preventing an augering operation also had to be considered. Reliable
records of the present facility do not exist, and there is no information on
the strata underlying the collection gallery and the concrete retaining wail.
The General geology in the area indicates alternate strata of pervious and
impervious materials, and it is possible that the present supply is from a
pervious tone Overlaying an impervious strata which could be penetrated by
vertica, drilling with consequent loss of production. Vertical drilling would
therefore have to be done with care and by stages using perforated casing and
probably frequent pumping tests as drilling proceeded.
Records of wells west and southwest of Springbrook were studied to
correlate their ground elevation and static artesian pressure with the Spring-
brook elevation 206. It did not appear that any well of record had a pressure
corresponding to the water derived at Springbrook. It therefore appeared
unl,kely that artesian pressure would be developed by vertical drilling at
Springbrook which correspondingly increases the possibility of losing the
present production to a lower zone. it would therefore appear desirable to
take 16-inch casing down to a clay stratum and seal, continuing with perforated
12-inch using lowered by stages and test pumped as conditions indicated.
• PROPJSALS FOR HORIZONTAL BORING
The writers contacted several firms listed as engaged in soil boring or
soil sampling. Of these, only Northwest Boring Company had the equipment to
do the work required. A meeting was meld on 14 April 1967 at the site, and
a letter dated 20 April 1967 with a proposal form was forwarded to that firm.
It was returned completed on 25 April 1967, and copies are bound to this report.
The proposal was reviewed by the writers on 28 April 1967, with a recommendation
that the work proceed by Northwest Boring Company. With the concurrence of the
City Engineer, the order to proceed was given on 2 May 1967. it was not possible
to obtain louvered pipe, and 3-inch x 3/16-inc sawed slots, 42 per foot, in
14-inch x 3/8-inch wall pipe were substituted. Due to a delay in Obtaining the
pipe, site work did not commence until 22 May 1967.
The equipment shown on Plate 1 moved in on 22 May 1967, and boring
proceeded during that day and the following day. After 12 feet of panetration
towards the north corner of the site, a large rock was encountered, and it was
not possible to drill farther. A total length of 45 feet of pipe was used,
and the completed work is shown on Plate 1,
with the experience gained from the first hole, it was decided to ask
�. prices for drillinq 24-inch casing, and again inquiries were made of other
firms without success. A further letter dated 25 May 1967 was sent to North-
west Boring and was returned on 31 May 1967 as a signed proposal and was
is accepted by letter dated 5 June 1967 for the work to proceed.

S�rin�brcck Source Aevelon'ent
Dear Jack:
Ce have considered devflDpment of the Springbrook source by drilling vertically
or horizontally into the hillside at the preseet Infiltration area. This letter
put% forward our recomandationo.
The City hunt develop the overall supply capability of the water averen in order
to keep Ahead of dmands vhich w111 be made upon It. in our opinion the Spring-
brook Area will oroduee more enter than is currently ovatlahle, and it, potential
4hould he tncreaoeA before drilling odditiopnl wells in the Alluvial fan of the
P CodAr eiver. However, if appreciable expenditure to to he incurred, then the
reliahtlity of the source and the trannmtsoion line to Talbot reservoirs meet be
considered.
Tate Springbra V source was first developed in 1909 and has been in cantinuou■
use iince t'.at data. Examination of City record, indicates that it has heen A
reltAhle source tiroughout the years. However, recent highway construction appeared
to reduce the flow to the City and regard must be had to the no+Atbility that the
t ex1,tin;t routs, could be disturbed by work at Sprtngbrook. Unlovs adequate precau-
tion% AT, taken, vertical drilling could result In leakage of high level -Ater to
strata below a confining layer. Por this reason it to preferable to first drill
horizontally into the hil!aide and develop tore water from the coarse gravel strata
which presently supply the City. There in also ages risk in horizontal drilling
becauae there is m way to visually doteratne the dip of the strata back into the
hill.,tde.
We racomend that horizontal perforated collector pipe., be drilled intc the
e hillatde And Dtped to a valve caisson connectod to the existing inlet chamber at
the head of the tranamtsaton line. This will protect the quality of the water And
providr A measure of control. Experience with the first collector Dips will Indicate
the number of colleetore required to develop the flow permttted under the water
right which is up to 9.28 efe (7 mgd).

additianal collector pipes could be !r.sr,.lir F. Inver down the creek which would
not remit water to flow by Rravtty to :.k:`at. It would then be Peeessary to
Provide low lift purnicg to the elevation of the existing inlet eheoMr. We
feel tAst it will be ponsible to 4evelon sufficient water to watlfy renlacemant
of tic 11,800 feet of 20-inch steel lino when. 'tr. condition warrants. The
replaeenent size would be subject to ecanomic evaluation.
It would be desirable to increase th. Pressure in tiro flat industrial area
scut". of Penton, and this can hs achtrvc;i by providing a staniclpe approximately
:.o fort hiRh at Snrinc:`rook. The resulting higher pressure would increaee the
fanacity of the erananission line to Talbot.
Construction at Snringbrook should aim at mai.ing the greatest ..se of vacsr
currently available, and to be developed, at the nre�ent facility or lower duwn-
stre,m.. A collection tank with low lift numps and duplicate pipelines would allow
full :evolor�ent of the source. The enclosed drawings Illustrate the proposed
facilities.
'C1th tiro degree of flexibility descril.ed above, we recomend that develoanent
of the source proceed by ntages. The consequences of the eventual stand Dine will
be discussed in a further letter dealing with develOrment at Talbot, distrthution
pressure macs, storage reseovoira, and Punos for the S.L. area.

On t*le r1unicip4l water system for the City of Renton prepared by Cornell, Itowland,
Ilay,,s a:,d Merryfiald (CI12M), October, 1965, postulated that the city, by 1985, wcild
knereasQ its eater service to 4L proportionate population increase, or approximately
57,0uv persons.

conducted by this of Y.ce has resultud in a sli6a:.ly higher figure, 140 gallons per
capita per day; however, all heavy incustrial demands were inclu,ied in our study.
The surgested 120 S,c'd figure used be Cli,M appears to the writer to be very real-
istic ana is used as a basis for the quantity reco=endacions. Consequently, the
annual demand is calculated to be 7661.3 acre-fcQt for tt.e p.ojected 57,000 population.
The euntinuous diversion of 9.28 c.f,s, would result in an annual volume of 6681.6
acre-Lear. Although approval is herein granted for the development of the entire
9.28 c.i,s„ it is the writer's opinion that difiiculties in developing this entire
quantity may be encountered.
In view of the fr:t that tho city already has a:: existing certificate of water right
for 2.3u c,f.s. an this source, 2.3o c.z.s, as gwuteJ u..der this application must
be considered as a eupplemertal right and 6,98 c.f.s, as :, primary right. It IN
thou-:Lt best to incl,idc tie quantity granted under the original right under this
filing lance there may be some goeation as to the validity of Certificate No. 463.
The C:tv of Renton wa, enjoined from using the waters in question in 1932 by the King
Court. Superior Court, the order contained the language that: "the defendant-
rc.pundant. City of Renton be, and it is, hereby enjoined from using the waters under
sat-' ,,rm,,t No. 1555 know Surface Water Certificate No. 463) until such time as they
have acquired th.> :i,ht by purcl,ase or by condemnation as provided by law," The
Washington State Supreme Court affirmed the decision of the lower court, 1Lere is
no evidence in the files of this office to indicate that the injunction was dissolved.
Ir •.-low of the fact that the City of Renton holds water rights totalling '761.8 acre-
feet under existing primary rights, the total annual diversion quantity, 6681.6, is
approved as a totally supplemental right.
As provided under RCW 43.21.130 and 90.03.360, a master meter shall be installed in
this system to masure the total amount of the diversion.
Use of the waters to b, appropriated under this application will be for a public water
supply. Santo Board it Health rules require every owner of a public water supply to
obtain written approval from the State Director of Health prior to any new construction
or alteration& of a public water supply. The applicant is advised to contact the
Washington State Department of Health, Fourth Floor, Public Health Build' g, Olympia,
with regard to the need for compliance.
In accordance with Section 90.03.290 RCW, I find that there is water available for
appropriation from the source in question and that the diversion proporud in the
application will not impair existing rights or he detrimental to the public welfare.
Therefore, permit should issue as recommended above, subject to existing rights and
indicateJ provisions.

Of Renton in this retard.
Ptc ha ro been un,-ble to verify all the water rights listed in the ropo: but
understand t:at t::O permits relate to recant applications by the City carry!: at
the recommendations made in our report of t,a water aystern.
Primary right is computed at 7661.3 aero-feet baacd upon a future po?ulation
of $7.Ci,o using UO-�allone per capita per day. This is the total amount of water
which i::e City can appropriate from all coarcea. The supplemental rights are granted
to per-..,t :he City to have flexibility in o."ratin; the water sources providing the
volan•.e ca.rr.eted at any one source does not exceed the quantity Zranted at that source
or to total the amount -f the Primary r13ht
The disputed validity of Certificate No. •:63 and the fact that rn a=ual quantity
was :,e' allocated at Springbrook mtroC,:ees a corn nlication which the Division of Water
Reseurc,_ has attem?ted to clarify. We undorstand that if Certificate No. 463 is
valid. :t wil. retain its original priorl.y in tl:v amount of 2.3 cis. M, in fact, the
eertif:c.:t, is not valid, the new certifica.a will cetablish a priority date at of the
date of Siling the recent application. In that way, 6. 98 cis would be a Primary right
and 2.3u cis a supplemental right to tho total amount of v.28 cis applied for. However,
