Re: Test pits w Cberry Ridge Apts.i Tract "C" ot' SP 707-91
Dear Ms. Vlilter::
As per your letter to Wyatt Architects dated August 25, 1995, test pits vvere duj at the
location of the proposed drywell and near the center of the pond.ing area. i measured and
exam.ined the two pits this morning, and have made the following conclusions:
1. The excavation at the drywell location C"East Pit") was made to elevation ?Ol 5.5, while
the pit near the center ot the pond.ing area ("West Pit") was made to elevation 2409.0.
Both pits coasist of coarse gravel and cobbles, apparently Gairison series material. There
is not really any soil at the pit sites, but rather vegetation-fre,e cobbles and gravel.
2. Since the pond floor is to be at elevation 2013.5, the bottom of the West Pit is 4.5 f'eet
below the pond floor. The material below the pond will be conducive to rapid draining of
water passing through the sod at the poad floor.
3. The proposed dryweil grate is to be at elevation 2014.0, putti.ng the bottorn ot'the
proposed Type =ZA" drywell at about etevation 2006. The bottom of the East Pit is
grate elevation and about 9 to 10 feet above the bottom of the drywell.
1.5 feet above the a
Obviously, more material will aeed to be excavated away to determine the nature di the
ground ai the drywell base. However, the parking lot ia Tract `B", immediately to the
west. was reportedly constructed on similar coarse material. The fiaished nrade nn the
asphalt west of the West Pit is about 2009.5. ~ WE. ~'°~E I V E D

4. aithough the site received about 2" of rain duriag _yesterday=s storm, there was absolutely
no standing water in either of the test pits. The c.Qarse material apparently drains quite
well.
As long as the material stavs consistent down ta an elevation af 2006 at the drywell locaiian_
I feeI confident the coarse materia] at the site will adequatelw disperse stormwater through
the drvwell. Likewise. the floor of the pond shouId easily empty within the required 72
hours by percolating througfi the porous subsurface material, with the sod providing the
Iimitine barrier to i.nfiltration. Although I don't aaticipate encountering any bedrock at the
drywe111ocation, the drywell location could be changed if bedrock is found. With the
topography and materials at the gites groundwater is very unlikely to be encountered.
Sincerely,
•

Memorandum
Date: May 16, 1995
To: Bill Hemmings, P.E.
From: Fsd Parry, P. E.~
Subject: SP707 - Cherry Street Desiga Deviatioa Requeat
1. This Deviation request proposes to (a) provide stormwater
management using a gravel percolation gallery in combination with
a presettling basin, and (b) to provide pipe flow velocities
slightly lower than the 4 fps required in the GSM.
The stonnwater facilities will collect runoff from the public
right-of-way for disposal in an easement on a private parcel.
2. Percolation Gallezy:
This concept provides a pre-settling basin to mitigate the
high unit surface loading rate on the percolation facility from the
contributing impervious area of Cherry Street. In addition, WSDOT
Type 1 catch basins are provided in the piping system; these catch
basins provide a sump below the pipe invert to trap out sediment.
The floor of the gallery will be located on the native soil,
and controlled fill will be placed to bring the area to grade for
the road and drainage facilities; sidewall outflow (as opposed to
floor outflow) can be expected. The calculations provided consider
floor outflow, but the facility appears to be adequately sized to
contain the 100-year event in the combined volumes of: (1) the
gallery, (2) the surface storage volume above the grate of the
inlet to the gallery, and (3) the available volume in the
presettling basin when analyzed using sidewall outflow. This
analysis has no provisions for freeboard above the maximum water
surface elevation.
These drainage facilities would be located in an easement
adjacent to Cherry Street.
The developer has indicated that the owner of the neighboring
parcel will grant slope easements for the construction of the fill;
overflow easements in lieu of additional freeboard would be
advisable.
3. Pipe Velocities:
Due to site constraints, velocities in the neighborhood of 3.3
fps are the best that can be expected at the design storm event;
while below the 4 fps required by the GSM, this is still well above
_ • . '
SP7 07
Desiga Deviatioa Request
Page 2 of 2
the 2 fps velocity commonly considered as the minimum needed to
prevent sedimentation in the pipes. The WSDOT Type 1 catch basins
provided in the piping system will provide a sump below the pipe
invert to trap out sediment.
4. R$COMMENDATIONS
a. The County Engineer should approve the proposed drainage
facilities, with these conditions
(1) The facilities will be maintained by the owner of the
underlying parcel.
(2) Erosion control during construction will be provided.
The pond area overlying the gallery cnay not be used as a
sediment trap; the pre-settling basin area may be used
for sediment control.
(3) Construction will be observed by the Engineer of
Record, and construction reports will be provided on a
daily basis during construction of the drainage
facilities.
(4) The percolation facility (gallery and surface pond)
and presettling pond are to be installed concurrently
with the road construction, and completed prior to paving
the road. Certified As-Constructed plans will be provided
to the County Engineer upon completion of the stormwater
facilities.
(5) In order to minimize compaction of the subsurface
matrix by construction traffic, a buffer area around the
percolation gallery footprint (5' adjacent to the street,
10' el sewhere ) shal l be f enced of f. No dumping of any
waste material will be allowed in either the percolation
gallery area or in the presettling basin area.
(6) Slope easements from the neighboring parcel owner
will be needed prior to plat approval.
b. The County Engineer should allow the lower pipe flow
velocities

RE: Short Plat: 707-91
Dear Mr. Hormann:
I would request that the existing cul-de-sac shown on the referenced short plat
at the present dead end of Cherry Street be vacated and returned to the land
area of Tract "C".
The improvements of paving and curbing for that portion of Cherry Street were
never accomplished.
As you will see on the final short plat drawing, a hammer-head style turnaround
is proposed at the northeast side of Cherry Street extended.
Thank you for this consideration.
Sincerely,

at the end of the cul-de-sac on Cherry Court. Field review verified that the signs have not been
installed. Travelers Casualty and Surety Company was called and their records indicate the
Caunty had authorized closure of the project on 9/5/03 and the bond was cancclled on 6/5/04.
Recommeadation - The cul-de-sac has changed since being constructed in 1996. There are now
approaches on both the east and west side of the cul-de-sac and guardrail across the north curb
drop where the signs should have been installed. We recommend considering this project closed
without any further action since the warranty bond has been cancelled. The City of Spokaue
Valley could consider installing the signs themselves if there are siill safety concerns.

The project punch list dated 6/18/03 regardi.ng inadequate drai.nage of the 208 swales has been
reviewed and we have field verified that sloping problems in the swales no longer exists. I
verified with Wasbington Trust Bank that both Letters of Credit have been closed.
Recomnendation - This project be considered closed without further actian.

The punch list dated 10/18/05 noted clogged inlets, debris and weeds in planting strip and
improperly constructed swales that need correction. There is debris trapped in the inlets and
these could be clearied out. There are weeds instead of grass growing in the planting strip. The
swales appear to have been constructed correcdy but have since been landscaped by property
owners since they were lacated behind the property fence line. Even with the landscaping the
swales are likely performing as intended. I am not sure if these are cleanup items that should be
done under warranty since construction was accepted and the warranty period iniiiated in 1998.
Bob Hepton, developer, is waiting till spring to laok at what work they will do. There is no
warranty bond but an amount equal to the warranty is being held in a savings account.
Paperwork derifying this is not available but I assume the information is correct since the
Hepton's have formally requested a release of surety through Landworks Development.
Recommendation - Cleaning the inlets and weeding the planter strip are the only construction
items, if any, that should be pursued. However, the inlets are still fwnctioning and the planting
strip does not appear to be irrigated and maintained so any temporary weed removal will not
solve the ongoing weed problem. Tbe swales lie behind property owuer fencing and restoring
them to a condition that existed at the time of acceptance will cnost likely upset the property
owners, be expensive aad difficult to accomplish, could possibly result in damage to existing
sidewalk and curb, and be of questionable benefit. We recommend immediate release of surety
wiless it is decided that it is the responsibility of the developer to weed and clean the inlets prior
to final acceptance.
Please contact me if you have any questions. If you agree with our recommendations, please let
me knaw by e-mail or a copy of the bond release letter so there is documenta.tion for closing out
the projects.

Memorandum
Date: May 16, 1995
To: Bill Hemmings, P.E.
From: Ed Parry, P.E.t

Subject: SP707 - Cherry Street Desiga Deviation Request
1. This Deviation request proposes to (a) provide stormwater
management using a gravel percolation gallery in combination with
a presettling basin, and (b) to provide pipe flow velocities
slightly lower than the 4 fps required in the GSM.
The stormwater facilities will collect runoff from the public
right-of-way for disposal in an easement on a private parcel.
2. Percolatioa Gallery:
This concept provides a pre-settling basin to mitigate the
high unit surface loading rate on the percolation facility from the
contributing impeYVious area of Cherry Street. In addition, WSDOT
Type 1 catch basins are provided in the piping system; these catch
basins provide a sump below the pipe invert to trap out sediment.
The floor of the gallery will be located on the native soil,
and controlled fill will be placed to bring the area to grade for
the road and drainage facilities; sidewall outflow (as opposed to
floor outflow) can be expected. The calculations provided consider
floor outflow, but the facility appears to be adequately sized to
contain the 100-year event in the combined volumes of: (1) the
gallery, (2) the surface storage volume above the grate of the
inlet to the gallery, and (3) the available volume in the
presettling basin when analyzed using sidewall outflow. This
analysis has no provisions for freeboard above the maximum water
surface elevation.
These drainage facilities would be located in an easement
adjacent to Cherry Street.
The developer has indicated that the owner of the neighboring
parcel will grant slope easements for the construction of the fill;
overflow easements in lieu of additional freeboard would be
advisable.
3. Pipe Velocities:
Due to site constraints, velocities in the neighborhood of 3.3
fps are the best that can be expected at the design storm event;
while below the 4 fps required by the GSM, this is still well above
I . . •
SP7 07
Desiga Deviation Request
Page 2 of 2
the 2 fps velocity commonly considered as the minimum needed to
prevent sed.imentation in the pipes. The WSDOT Type 1 catch basins
provided in the piping system will provide a sump below the pipe
invert to trap out sediment.
4. RECOMM M ATIONS
a. The County Fngineer should approve the proposed drainage
facilities, with these conditions
(1) The facilities will be maintained by the owner of the
underlying parcel.
(2) Erosion control during construction will be provided.
The pond area overlying the gallery may not be used as a
sediment trap; the pre-settling basin area may be used
for sediment control.
(3) Construction will be observed by the Engineer of
Record, and construction reports will be provided on a
daily basis during construction of the drainage
facilities.
(4) The percolation facility (gallery and surface pond)
and presettling pond are to be installed concurrently
with the road construction, and completed prior to paving
the road. Certified As-Constructed plans will be provided
to the County Engineer upon completion of the stormwater
facilities.
(5) In order to minimize compaction of the subsurface
matrix by construction traf f ic, a buf f er area around the
percolation gallery footprint (5' adj acent to the street,
10' el sewhere ) shall be f enced of f. No dumping of any
waste material will be allowed in either the percolation
gallery area or in the presettling basin area.
(6) Slope easements from the neighboring parcel owner
will be needed prior to plat approval.
b. The County Engineer should allow the lower pipe flow
velocities

installing, operating and maintaining drainage swales and drainage facilities, as conditions
of plat approval, are hereby granted to the public.
2. Spokane County and its authorized agents are hereby granted the right of ingress and
egress to, over, and from said easemeots for the purpose of inspection and emergency
maintenance of water quality veatment swales ("208 swales") and other drainage
facilities, if not property mainta.ined by the property owner. Spokane County does not
accept the responsibility to inspect or maintain the drainage easements, drainage swales,
or subsurface drainage facilities located outside of the pubiic Right-of-Way, nor does
the County accept any liability for any failure by the lot owner(s) to properly maintain
such areas.
3. The property owners within this Plat shall be held responsible for keeping open and
maintaining the surface path of natural or man-made drainage flow over and across their
respective properties.
4. The property owners within this Alat shall maintain all water qualiry treatment swales
("208 swales") and drainage ditches situated on their respective properties, and any
portion of a 208 swale situated in the public right-of-way adjacent to their respective
properties, with a permanent ground cover as specified on the current appraved plans on
file at the Counry Engineer's Office. The property owners shall also maintain, repair,
andlor replace the subsurface drainage facilities located outside the public Right-of-Way
on their respective properties.
5. The property owners may install approved shrubbery and/or trees which do not obsvuct
the flow and percolation of storm drainage water in the 208 swale and drainage ditches,
as indicated by the current approved plans on file witil the County Engineer's Office.
7. Spokane County does not accept the responsibility of maintaining the drainage course on
private lots within drainage easements or floodplain areas, nor the responsibility for any
damage whatsoever, including, but not limited to, inverse condemnation to any properties
due to deficient construction and or maintenance of drainage courses in drainage
easements on private property.
8. If the property owner fails to maintain the surface path of natural or man-made drainage
flow, or the drainage swale, a notice of such failure may be given to the property owner.
If not corrected within the period indicated on said notice, Spokane County has the right
to correct the maintenance failure, or have it corrected, at the expense of the property
owner.
9. Any building that is constructed on a lot in this Plat shall be set at such an elevation so
as to provide positive drainage away from any drainage entry point to the building
(including but not limited to a window well, a window unprotected by a window well,
or a doorway). Said positive drainage shall consist of a mininlum slope of 3% away from
the building for a distance of at least 10 feet from the building. The lots shall be graded
so that either a) all runoff is routed away from the building, and conveyed over the lot
to a natural drainage swale or approved drainage faciliry, or b) drainage intercepted on
the lot is disposed of on the lot in an approved drainage facility. The approved drainage
facility shall be constructed in accordance with the approved plans on file at the County
Engineer's Office. Any revisions to the approved drainage plans must be approved by
the County Engineer's Office prior to construction of said revisions.
10. The Plat is located within a drainage basin which has been identified by Spokane County
as having stormwater runoff problems. Since this Plat is affected by, or is a contributor
to stormwater flows, the property owners, or their successors in interest, agree to
participate in the planning and implementation of a future basin-wide stormwater
managernent system and/or assessment district. The property ownersT or their successors
in interest, agree to pay such rates and charges as may be fixed through public hearings,
for service or benefit obtained by the planning, design, construction, mainteaance, or
operation of stormwater control facilities.

Approval
Gentlemen:
I am enclosing a sepia and a blueline print of the road and drainage plans for this project with
the Cauaty's approval scamp; the original mylars are on file at the Public Works Department.
A copy of the drainage calculations (stamped "Approved") are also enclosed. In accordance
wit6 Section 2.02.A.3 of the SCRS, this approval is valid until June 5, 1997. If the facilities
are not constructed, you may request an extension for an additional two years; the plans shall
be revised to reflect current standards prior to granting the extension.
Please oote that this approval is subject to the following conditions. These conditions were
previously noted in our letter of May 24, 1995, which approved the Design Deviation Request
for this drainage concept:
(1) The facilities will be maintained by the owner of the underlying parcel.
(2) Erosion control during construction will be provided. The pond area overlying the
gallery may not be used as a sediment trap; the pre-settling basin area may be used tor
sediment control.
(3) Construction will be observed by the Engineer of Record, and construction reports
will be provided on a daily basis during construction of the drainage facilities.
(4) The percolation facility (gallery and surface pond) and presettling pond are to be
installed concurrently with the road construction, and completed prior to paving the road.
Certified As-Constructed plans will be provided to the County Engineer upon completion
of the stormwater facilities.
(5) In order to minimize compaction of the subsurface matrix by construction traffic, a
buffer area around the percolation gallery footprint (5" adjacent to the street, 10'
elsewhere) shall be fenced off. No dumping of any waste material will be allowed in
either the percolation gallery area or in dle presettling basin area.
(6) Slope easements from the neigbboring parcel owner will be needed prior to plat

infiltration facilities, with no definite option decided yet.
3. Parry explained how the draft amendment to the GSM evolved, and
the sources for technical information. Criteria for site selection,
and site feasibility were discussed, as were various design
parameters for the various concepts. McMulkin decided to read
through the copy of the amendment provided, and to pencil up some
concepts for discussion.
4. Wyatt noted that the owner of the neighboring parcel to the
north is agreeable to placing fill on that parcel in support of
this project. Parry noted that a Slope Easement Agreement would be
needed prior to finalizing the Plat, and that the County would
draf t this Agreement from ownership and legal description
information to be provided by Wyatt.
5. Parry requested that future submittals also include topographic
information.

Gentlemen:
We have completed a review of the proposed drainage concept for this project. Given the high
groundwater table and the shallow bedrock indicated in the Ge4technical Report, i.his site is a
poor candidate for the underground percolation gallery proposed. In addition, a site feasibility
analysis indicates that this sort of facility with this site configuration would not have a reasonable
chance of providing a successful service life.
I therefore eannot accept this proposed drainage concept, and am returning one copy of the plans
and calculations you submitted on February 16th, 1995. Should your clien[ decide to continue
with this project, I strongly encourage you to meet with the Development Engineering Services
Section to work out an acceptable drainage concept.
If you have any questions about this mattert please contact Mr. Bill Hemmings, P.E, or Mr.
Eci Parry, P. E. at 456-3600. Thank you.
Very truly yours,

FROM:: Cliris Reich -SUBJECT: Short Plat 707
DATE: Februar,y 22, 1995 °
- ~ .
The "fo~ilowing is prepared in accordance-to the Amendment to the GSM dated January
25", 199,5'.
As outline'd, if any of the site selection 'criteri'a are. not rnet then the site, will' be
deterrnined to- be inadequate for subsurface disposal. The following is a s"ummary of.:
those items:
Grountlwater
The three bo~rings conducted at,the proposed location did. not-.encounter,
~ -
G1JV, but the soils wer.e saturated at approximately 2' below tiie existin'g
ground surface.
Bedrock I
6edro,ck wa& encountered at 5" bblow existing grade.
Fill Material
The infiltrating surface will be placed.on approximately 3' of fill. The f ill
material is not specified. Infiltration Rate
According to County report, it is.-recommended to use 5 ih/hr.
Existing/Proposed Slopes The pond banks are proposed as '2:1. The existing ground slope is not
shown, since a site topo is ~not provided.
i ~
Subsurface Conveyance Capabilities
Thi's is not known since geotechnicai repon is limited to the pond
location.
Increase Subsurface Volume
The 10 year volume is 634 cf. The. 100 yeae volume is
Septic Drainfields.
Information is not provided to determine 'if this criteria is ~met.
Drinking, Wells.
Information is not provided to determine if -this criteria is met.
The site feasibility evaluation indicates. this -site isnot adequate for the ptoposed
_d6skgn. Ttie site fails the point= test only scoring 15 pts. Also, this proposal is not
ad'equate because the ratio of impervious area,, to infiltration area is approximately
10:1.
In conclusion, -the, proposal as presented does , not meet the cequirements of the
.~~~amen*dments .as outlined in 'the January 24, 1995 rr~emo fr.om Ron Hormann, P:E.,,

REPORT OF FIELD PERMEABILITY TESTING FOR PROPOSED NEW CIiERRY
STREET EXTENSION PROJECT, SPOKANE, WASHINGTON
This letter summarizes the results of borehole percolation
testing for the proposed new Cherry Street Extension project,
located east of Pines Road at the present north end of Cherry
Street, in Spokane, Washington. The purpose of the work was
to provide percolation and permeability data for design of a
proposed new stor;n water disposal system associated with the
proposed Cherry Street Extension.
The work was accomplished in general accordance with our proposal
of August 25, 1994, which was authorized by Mr. Roy Wyatt on
November 23, 1994.
PROJECT AND SITE DESCRIPTION
We understand that you plan to extend Cherry Street approximately
300 ft. northeast from its present dead-end location. The
praposed extensivn will terminate at a cul-de-sac, where a storm
runoff callection and disposal system, consisting of drainage
ponds and drywells, will be constructed. The new storm drainage
facilities will be located east and west of the proposed cul-de-
sac. See Fig. 1.
Presently, the site is wooded with mature pine trees. The ground
surface generally slopes down from the existing dead-end to the
proposed new cul-de-sac location. Several rock outcrops are
visible to the east of the proposed extension. New apartment
buildings are under construction northwest of the proposed new
cul-de-sac.

BOREHOLE PERCOLATION TESTING
On November 15, 1994, three hollow-stem auger boring attempts
were made at the approximate locations shown on Fig. 1. 8oring
101 was augered to a depth of 4.0 ft. below existing ground
surf ace ( GSE ) and sampled f rom 4.0 to 5.5 f t., us ing a standard
split-spoon drive sampler in general accordance with ASTM D 1586.
The recovered sample was described as medium dense, moist, brown,
silty, gravelly SAND; derived from decomposed granite gneiss.
Boring 101 terminated with auger refusal at 5.5 ft. When the
auger was removed, the boring caved to 5.0 ft.
A second boring attempt (B-102) was made at a location about
6 ft. due west of B-101. It terminated with auger refusal at
2.5 ft. A third boring attempt (B-103) was made at a location
approximately 2 ft. south and 3 ft. west of B-101. B-103 ter-
minated with auger refusal at 5.0 ft. When the auger was re-
moved, B-103 remained open to a depth of 5.0 ft. Based on the
proximity of nearby granite gneiss outcrops, we believe that all
three borings refused on gneiss bedrock, or large boulders. No
ground water was encountered in any of the borings.
The drilling work was accomplished using a CME-75, truck-mounted
drill rig and a 7-1/2 in. O.D. by 3-3/4 in. I.D., hollow-stem
auger. The drilling and subsequent percolation testing was
performed under the direction of Mr. David S. Phelps, aur geo-
technical engineer. The drilling and borehole percolation
testing was also observed and recorded by Ms. Linda Broscheit,
an engineering technician from the Spokane County Engineering
Department. A copy of the Spokane County Engineering Department
Report is included as Appendix A.
A percolation test was conducted in general accordance with
the Draft Interim Percolation Standards, dated February 1992, as
provided by the Spokane County Engineers Office. This procedure
consists of installing a 6 in. I.D, perforated casing, wrapped
in non-woven filter fabric; saturating the subsoil; and then
performing a falling-head permeability test to establish soil
permeability parameters.
TEST RESULTS AND RECONMENDATIONS
The percolation testing was conducted in B-103. The test in-
cluded installing a temporary, 6 in. diameter, perforated casing,
wrapped in non-woven filter fabric and inserted into the borehole
to a depth of 5.0 ft. below existing ground surface. Saturation
was achieved by maintaining a constant head of water in the
casing, even with the ground surface, for one hour. Approxi-

mately 89 gallons of water were required to maintain the constant
5 ft. head over the one hour saturation period. Following the
saturation period, the water level was allowed to fall and
periodic measurements were made over a one hour period to deter-
mine the rate of percolation.
The following borehole percolation data were analyzed to deter-
mine approximate percolation and permeability rates.

In our opinion, based on the field testing described previously,
we believe that a design percolation rate of approximately
18 in./hr. would be appropriate for drywells at this site.
We understand that the Cherry Street Extension project may
require significant regrading and filling of the site. In our
opinion, drywells located fully or partially in clean sand and
gravel f ill may have a design percolation rate somewhat higher
than that estimated for the native soil conditions.

RE:' CHERRY STREET EAST OF PINES AND NORTH OF I-90 NEAR GRACE
(SHORT PLAT 91-707)
Bill,
I am transmitting 2 copies of Linda Brosheit's report detailing work conducted on the above
project by Gifford Consultants on November 15, 1994. The work consisted of drilling 3
boreholes to refusal and performing I borehole percolation test.
The results of the investigation and testing indicate that the site is poorly suited to subsurface
disposal of stormwater. The area is hilly and rock outcropping9 aze scattered throughout the
site. Refusal upon the underlying granitic bedrock was encountered at 5+1/2 feet, 2+1/2 feet
and 5 feet in test hole #l, #2, and #3 respectively. Linda noted saturated soil at a depth of
minus 2 feet in all three of the boreholes.
i
The single borehole percolition test was conducted in borehole #3. Approximately 89 gallons
of water was used to maintain the water level at the surface during the one-hour "saturation"
period. The "percolation" rate based upon a gross one-hour period was measured at 23 inches
per hour. The "perc" rate based upon the ]ast 15 minute interval of the test was calculated as
approximately 5 inches per hour.

A map showing the locations of ihe boreholes is included in Linda's report as figure #1.

On November 15, 1994, Gifford Consultants, Inc. conducted a field
pbkcolation test and a subsurface soil investigation. The tests
were conducted for the proposed extension of Cherry Street: east of
Pines and south of Grace. The weather for November 15 was liqht
rain and approximately 35 degrees.
The soil type in this area is generally Garr ison-Marble-Springda le
association: somewhat excessively drained and excessively drained
sandy and qravelly soils formed in glacial outwash according to the
United States Department of Agriculture and Soil Conservation for
Spokane County. The test site and surroundinq area is timbered and
hilly with rock outcroppings. Rocks were visible on the grounds
surface with the maximum size approximately two feet. The soil was
silty medium to coarse sand with gravel. At test hole #1 a soil
sample was taken at *4 1/ 2 to 5 f eet . The sample showed the so i 1 to
be decomposed granite at this depth. Refusal was met at
approximately 5 1/2 feet at test hole #1. Test hole #2 met with
refusal at approximately 2 1/2 feet. Test hole #3 met with refusal
at approximately 5 feet. In all of the test holes a layer of
nearly saturated slil was encountered at approximately 2 feet. The
location of the test holes are shown on Figure l.
The area where the bore holes were drilled has the potential for 6
to 8 feet of fill for the extension of Cherry Street.
t
TEST PROCEDURE AND REBULTS
Although the depth needed to conduct a field percolation test for
a single depth drywell was not reached, a test was conducted at
test hole #3. The test proceeded in general accordance with the
Spokane County Interim Percolation Test Standard Method which has
a minimum requirement of 72" per hour.
TEST HOLE #3
Test pit #3 was bored to a depth of refusal of approximately 5
feet. The location is shown on Figure 1.

I. PROJECT LOCATION AND DESCRIPTION
This project is located north ofi Mansfield Avenue and east of Pines
Road. The plat proposes 4 multi-family or commercial lots totaling
approximately 11.7 acres. The site consists of grass, rock and scattered
trees.
In accordance with "Soil Survey, Spokane County, Washington", 1968, the
soil is categorized as:
(,-,StC, Spokane very rocky complex, Spokane loam , moderately shallow,
depth to bedrock is between 20 and 30 inches, rock outcrops

Drainage calculations were made only for Cherry Street, since the
future lot conditions are unknown at this time. Orainage calculations
for individual lots will be made when building periiii ts are requested.
Cherry Street was divided into two (2) basins; left and right. Each
basin is composed only of asphalt pavement.
In each basin, storrriwater flows along the curb and into a grass pond
near the north end of the plat through a curb opening. The grass ponds
were calculated to hold -the first 1/2" of rainfiall runoff over the a5phalt
street areas.
Figure 2, page 6-3, of the "Guidelines for Stormwater Management", by
Spokane County Engineers, was used for rainfall intensity and duration
occurring at a 10-year storm frequency. .
The Rational and Bowstring Methods were used to calculate the ueak
s to rmwa te r ru nof f f o r each bas i n, a nd t he type and nu mbe r of drywe 11 s
needed for each basi n based on the storage capaci ty of the pond.

'The- grass -p,ercolation, area (or "pond") ha"s been, siied'to accommodatc the "208 " v.olunie

The drainage pond will be. a mihzuuni oF 9", deep with 3:1 (horicontal-to-vertical)
side slopes,,and thc=entire pand wi.U tie lined with,,urass:sod. p. low-profile drywell,will be

, volurnc; of tlie',gallery., including, tfle-sp,eciliec! dryweli,. is 30"x 40'*x 27" = 2,70011'.
Storm'water wiWfi.ll .the p-Qnd td:adepthof .6" before flo.wing through the grate: '1"hz

Outtlow~of stormwater is accomNlished by percolation -throug1vthe;- trench.floor.and walls
-int,o tliz adj6ining soils., Tlie, outrlow raie was,:detemvntd by ffEld testing, p4r~rmed by
Giffard% Consultants, Inc:.on November l:S,, 1994.; According,to their report; borzhoie

'rhe soil perralation rate is per sq. foot of gr<1vc:l bed are.a, assumiog venir,al nuttlnw nnly.
Outtlow through the floor of the intiltration gaUery is calculated using Gifford', I8"/hour

the luw-profdc drywcll dinlensions of 5'-2" x8'-U" (duc tn tlic solid concrete base) i'ur

Storage of stormwater in excess of the outflaw rate is accommodated witfun the va;d
vc.ilume of the infiltration gallery, and in the fir5t 9" ot pondin5 d4pth dn the surfacc. I'he
vulume of availabte siarage within the drainrock can be expressed as fnllovvs:

DRAINAGE REPORT
for proposed extension of
Cheny Street
at
Short Plat 707-91
For: Roy Wyatt
May 3, 1995
This proposed project is within an area that may be regarded as a drainage problem area,
due to shallow soils and rather slow percolation rate. As sucli, geoteehnical field tescing
was required to determine the existing soils' capacity for stonnwater disposal (see the
Gifford Consultants, Inc. report tnr this project). Due to shallow depth to bedrock and
!ow permeability of the native soil, the use of conventional dryweUs for stormwater
outflow is not appropriate. However, the geotechnical investigation and the attached
calculations indicate that a conventional "208" drainage pond coupled with a subsurface
percolation gallery and low-profile drywell could adequately dispose of the anticipated
stormwater volume.
Tbe stormwater dra.inage plan coasiders tlie street as a single drainage basin. The
stormwaier from the left and right sides of Cherry Street flows into catch basins and
piping in the cul-de-sac, and empties into a presettling basin on the right (east) side af ttie
eul-de-sac. It is proposed that the catch basins will collect most of the solids from the
stormwater, and the presettling basin will settle out the remaining suspended solids and is
sized to provide "208" treatment on the first 1/2 inch of rainfall. The proposed drainage
pondJgallery will be constructed on the right (east) side of the cul-de-sac. The stormwater
will flow from the presettling basin into the drainage pond for storage on the surf'ace, a.od
the percolation gallery below the pond will provicle outflow underground. The drainage
pond is also sized to provide "208" treatment on the first 1/2 inch of rainfall. The
stormwater colleeted in the pond will enier the percolation gallery via a grate on a low-
profile drywell. The percolation gallery consists of an excavation of specific dimensions
(30' x 40'), lined with filter fabric and fiUed with drainrock.
1-2 METtiODOi.OGY
Stonnwater runoff control has been designed following Spokane County's "Guidelines For
Storrawater Management" as closely as possible. Since this site is in a potential "drainage
problem area" with somewhat shaliow soils, a design de4iation has been requested.
In lieu of standard drywells, a shallow "percolacion gallery" is proposed fnr outflow of
stormwater from the site. In designing these galleries, both 10-year- and 100-year
storm return frequency events are assumed, and peal: ruaoff and storage requirements
for the two storms are calculated using rational and bowstring methods.
The grass percolation area (or "pond") has been sized to accommodate the "208" volume
as per Spokane County Engineers' guidelines. Storm runoff volumes are contained as per
Spokane County's policy for gravel percolation galleries, which call for storage of the 10-
year excess valume within the gravel envelope, and capacity within the gravel combined
with the pond dead storage (above the grate) to store the 100-year volume.
The drainage pond will be a minimum of 9" deep with 3:1 (hnrizontal-to-veracal)
side slopes, and the entire pond will be lined with 6nass sod. A tow-profile drywell will be
in$talled beneath the pond, with the grate 6" above the pond floor. The remainder of the
gal.lery, surrounding the drywell, wiU be filled with drainrnck to a total depth of 27". The
volume of the gallery, including the specitied drywell, is 30' x 40' x 27" = 2,700 ft'.
Stormwater will fill the pond to a depth of G" before flowing through the grate. The
low-profite drywells will discharge stormwater through the drainrock to the soil. Void
volume in the underground galleries is assumed at 30°10 of the total gallery volume for
storage of stormwater; thus, void voluaie is 30% x 2,700 ft' = 810 ft3.
Outflow of stormwater is accomplished by perc;olation through the trench flonr and walls
into the adjoining soils. The outilow rate was determined by field testing, performed by
Gifford Consultants, Inc. on November U. 1994. According to their report, borehole
percolation data indicate a pernieability rate of 0.24"/hour and a percolation rate of
23.3"/hour. The report states that a design percolation rate of 18"/hour is appropriate
for drywells at tWs site, and is thus the figure used to calculate outflow from the gallery.
This drainage analysis includes calculations made with a bowstring spreadsheet program.
1'he spreadsheet uses the "soil perc. rate" in inches per hour to c;alculate outflow from the
under,ground gravel galleries, without a,iy allowance for head or latecal infiltration. This
method is somewhat conservative, especially since the 18"/hour figure is already a
conservative figure for this site, and since only veriiccrl outflow is credited.
Thz soil percolation rate is per sq. foot of gravel bed arca, assuming vcrtical outtlow only.
Outflow through the floor of the percolation gallery is calculated using Gifford's ] 8"/hour
recommended soil percolation rate and the gallery tlaor dimensions ot' 30' x40' , m,inus
the low-profile drywell dimensions of 5'-2" x 8'-0" (due to the solid concrete base) for
the wetted area, as fallows:
Q=(soil percolation rate) x[(gallery width x lengnh) -(drywell width x length)]
=(l s"nhouT) X[(30' X ao') - (s.17'X s.o')]
_ (367day) x [(1200 ft-.) - (41.4 W.)J
_ (36'/day) x [ 1158.6 ft'.]
= 41,710 cu.ft./day
= 0.483 cfs
Storage of stormwater in excess of the outilow rate is accommndated within the void
volume of the perc;olation gaUery, and in the first 9" of ponding depth on the surfaCe. The
volume of available storage within the drainrock can be expressed as follows:
Usable Void Volume = 300/o of total percolation gallery volume
= 0.30 (length x width x depth)
= 0.30 (30' x 40' x 2.251j)
= 0.30 (2,700)
= 810 cu. ft.
Summary Table 2-2 includes data on t6e intlow and outflow rates and underground
storage capacity for the proposed percolation gallery.
The drainage design for this ptoject achieves the follawing goals:
l} Pravide sufficient storap-e canacity wittun the void volume in the percnla#ion gallery
to store the volume generat+ed by the 10-year storma less the cmculated autflaw;
2) Pr4vide su.fficient storaee canaciN witlun the ~,rr'assed pand, above the tirywell grale
(between 6" and 9" ponding depth) combined w1th the void volume in the percoIativn
gallery, to store the voluzne generated by the 100-year storm, less the autflow; and
3) Proride sufficient nutflaw caoacifiv via the underground percalation gallery to empty
the storei aoIume within 72 hours maximum.

NOTES:
Outflow Rate is calculated as described in Section 1-2, using Q=(soil percolation rate) -
x(wetted area), with outflow only through the floor area of the percolation gallery, less
the dryweU base area.
Gallery Void Volume is assumed to be 30% of gallery total volume.
Stormwater Volume of each storm is the peak volume in excess of the outflnw rate,
as per the bowstring calculations.
i 0-year Storage Provided is the Gallery Void Valume.
] 00-year Storage Provided is the Gallery Void Volume plus the Pond Storage Volume
above the g7ate (volume @ 9" depth minus volume @ 6" depth, Table 2-1).
Time to Empty: 10-year is the 10-year Stormwater Volunie divided by the Outflow Rate
for the basin. Time to Empty: 100-year is the time for the 6" of ponding depth below the
grate in the pond to percolate through the sod (assuming 0.40000833 cfs per sq. ft. of
pond floor area), which is the slowest parameter of the total outflaw rate.
2-3 POND VOLUME CALCULATIONS
For a drainage pond with 3:1 side slopes on all sides, the pond volume can be calculated
with two components: the volume directly above the floor area plus the volume above the
side slopes. Votume is calculated at 6" depth and at 9" depth, with the d'ifference
providing for storage of excess volume frnm the 100-year storm.

RESIILTS OF SOIL SAMPLING AND SUBCONTR.ACT R-VALUE TESTING FOR THE
CHERRY STREET EXTENSI4N PROJECT, SP4K,A.NE, WnSHINGTON
This letter presents the results of soil sampling «nd subconLract
R-value testing for the Cnerry Strzet EAtension project, in
Spokane, Washington. The purpo.v-e of tii.is wark aias to provide
5oi1 strcngth parameters for pavemznt ciesign for che proposcci
netid sCrezt.
Vie understand that the Cherry Street Extznsion project includzs
construccing a new 300 ft. long paved roadway, as shown on rig.
1. Thz roadway subgrade wi11 be construcced of sail maceridl
excavated from the area west of the termination of the edisting
Chzrry Street alignmcnt.
On May 12, 1994, wz collected a represzntativz bulk scil sGmp1e
trom the praposed excavation area, dt Lhe apprcximate loc«tiot'i
shown on Fig. 1. The sampla was col lecced fz cm about 0.5 f c.
helow thz ground surface. It was visually classified, in gen`ral
accoidance with thz procedures dcscribed in ASTt-t D?4a8, as sandy
GRAV2I, wi rh numerous cobbles.
The sample was.testzd far R-value in general dccordancz with
tiSDOT Method 611. Test results, which arz prcsznted in Table 11
indicate an R-value of 75. '

't'he soil percolation rate is per sq. foot of gravel bed area, assuming verticil auttlow onl_y.
Outilow through the floor of the infittraUon gallery is calculatzd using C;itford's 18"/hour
reeommencled snil percolation rate and ihe gallery floor dimensions nf 30' x4U' , minus
the low-profile drywell d'unensions of 5'-2" x8'-U" (duc fio the solid concrete biisc:) tur
the wettc:d area, as follows:
Q _(soil p`r.;olaiion ratc;) x[(galtcry width x length) -(cli-ywell width x lcngth)J
_ (1 8"/liour) x [(30' x 40') - (5.17' x 8.0')]
= (36'/day) x [(1200 11'.) - (41.4 W.)J
= (36'Iday) x 158.6 ft2.]
- 41307 10 cu.fi.lday
= 0.483 cfs
Storage uf stormwater in exCess of the ourilow rate is accotiamodatecf withiii the vuict
vvlume of the inFiltration gallery, and in the first 9" of ponding d4pth on the surface. I he
volume ot'available storabe within the druinrock can be exprc-ssed aa iollows:
Usable Void Volume = 30n/o of total infittraUon gallery volumc
= 0.30 (length x width x dcpih)
= 0.30 (30' x 40' x 2.25')
- 0.30 (2,700)
= b 10 cu. 11.
Summary Table 2-2 includes data on the inilow and outtlaw rates ancl undErground
storage capacity for the proposed infiltration gallery.
1'he drainage dzsign for this project achieves thz following gaals:
1) Provide sufficizat storage canacity witlun the void votunle in the intiltration gallery to
store the volume generated by the 10-year storm, less the calculated outfluw;
2) provide suflicient storae-e canacity within the gras.sed pond, above t12e dry~wCtl grate
(bctwcen 6" end 9" ponding depth) combuiecf with the void volumc in thz i.ntilt ration
gallzry, to store the volume generatExl by the 100-year storni, less the outtlow; and
3) Nrovide sufficient outflow capacity via the undzrground infiltration gallM to ci-npty
the stored volunie within 72 hours maxiniuni.
