_ DRAINAGE REPORT
for
NORTHWEST CORNER OF MISSION AND PINES
Proj ect Description:
This project is a commercial development of 3.6 acres. It includes one retail building,
one office building and one future pad site. The project is on the west side of Pines
Road, north of Mission Avenue. The site was previously unoccupied.
Methodology:
The procedures as outlined in "Guidelines for Stormwater Management" as published by
Spokane County Engineers was followed. The rational method is used with a 10 year
return frequency for on site drainage. No off site drainage flows onto the site.
Soils: (See map, Attachment "A")
Soils are classified as GgA - Garrison Gravelly Loam in accordance with the "Soil
Survey, Spokane County Washington, 1968".
GgA - 0 to 5 percent slopes. Gravelly, medium-textured, somewhat excessively drained
soils formed in gravelly glacial outwash material from a variety of acid, igneous
parent rock; on nearly level to moderately sloping terraces; depth to mixture of
sand, gravel, and cobblestones ranges from 2 1/2 to 5 feet. This soil group is
acceptable for drywells per the GSM.
Topographic Data: (See map, Attachment "B")
The site generally slopes to the north with grades varying from 1% to 5%.
Demographic Data:
The site is currently unoccupied. Upon completion this site will contain a retail building,
an office building and a future pad site.
: Drainage Report, Northwest Corner of Mission and Pines Page 1
September 7, 1994
Rainfall Data:
Data used is in accordance with Figure 2, page 6-3 of the "Guidelines for Stormwater
Management", by Spokane County Engineers. A 10 year return frequency event was
used. This chart is included with the calculations of this report.
Methods of Runoff Control:
Control will be by four drainage basins which flow overland to grass percolation areas
(GPA's) and drywells located in the landscaped areas of the site. Roof areas will be
piped directly to drywells. All GPA's will be sodded for treatment.
Methods of Disposal:
Four (4) grass percolation areas, one for each drainage basin, will be utilized. All
swales contain one (1) each Spokane County Standard single depth drywell. Swales and
drywell capacities were sized using the 10 year on-site storm.
Peak Flow, Volume and Disposal Calculations:
a. Hydrology Computations:
The site has been divided into four (4) basins labeled alphabetically.
o Basin A lies on the western side of the site and includes parking and sidewalk
areas around north and east sides of the retail building and landscaped areas along
the west and north.
o Basin B is just east of Basin A and contains parking, sidewalk and landscapes
areas in front of the office building.
o Basin C lies just east of Basin B and contains the same surface types as Basin
B, but sits in front of the future pad site.
o Basin D, lying east of Basin C and the future pad site, contains parking and
landscaped areas. All basins flow overland and deposit directly into the GPA's
for disposal. (See attached calculations).
Hydrology calculations were also performed on the roof areas. The retail
building roof generated 0.95 cfs and is disposed of by one (1) double depth
drywell. The office building roof generated 0.44 cfs and is disposed of by two
(2) single depth drywells. Flows were estimated for the future pad site assuming
a conservative 10730 sf roof would generate 0.70 cfs and would require one (1)
double depth drywell for disposal. The drywell and piping to the future pad site
will be installed with this development for future connection.
Drainage Report, Northwest Corner of Mission and Pines Page 2
- September 7, 1994
b. Inlet Capacities:
Three (3) curb inlets are utilized with this design, two in Basin B and one in
Basin C. Individual calculations for each inlet show that widths of two (2) feet
will sufficiently pass the generated flow. Curb inlets are located at the low spot
of each basin area and any flow surpassing the capacity of the inlet will flow over
the curb and still flow to the GPA's.
c. Detention/Retention Storage Capacities:
Grassed percolation areas were calculated to hold the first 1/2" of runoff over the
entire parking lot area. See Calculations on the following pages. Grass
percolation areas are a minimum of 6 inches deep and will be sodded.
d. Pipe System Capacities:
Pipe diameters were calculated to handle each roof basins peak runoff for a 10
year storm event. Connecting to the building roof drains just outside the
building, runoff is routed to collection pipes for conveyance to the drywells.
Piping was designed for the retail and office buildings only. Each building
required a small closed conduit system which did not appear to warrant back
water calculations. Manning's equation was used to size roof drain piping and
velocities of greater than 4 feet per second were maintained throughout. All
pipes are sized conservatively, with capacities well above the calculated 10 year
storm flow rates.
A roof schematic for each building and sizing information can be found on the
attached pages.
Remarks:
The above described system of stormwater control will provide the quality and quantity
controls as outlined in the "Spokane County Stormwater Management Guide" for the
Northwest corner of Mission and Pines.

Billy:
Enclosed you will find a reduced copy of the parking lot area, nearest the existing pump station for the
referenced project. You will notice that the items discussed in our phone conversation of November 8, 1994
have been addressed and are inciuded in the final document.
The curb drop noted on the facsimile your office sent to Taylor Engineering, Inc., dated November 7, 1994 is
not necessary since the edge of the asphalt at that location does not have a concrete curb. It is finished with a
metal edging and the area betweea the edge of concrete and the pwnp station fence is back filled with gravel.
This assures you have complete access to your pump station along the entire south side.
As was discussed and accepted during our phone conversation, we will pave the entire parking lot as shown.
We are making the two stalls in the upper northeast corner unavailable for use until the County abandons the
pump station and no loager needs access to the station. These stalls will be striped and painted with a`Wo
Parking" sign. One additaonal sign is supplied at the head of the south end of the "No Parking Zone" for
clarity in the event the parking lot striping is obscured due to snow accumulation,
A"Coatractors General Note" has been added to the document stating that access to the pump station must
be maintained at all times during construction. , .
' This addressses all of the concerns put forth by your department Your timely response on this matter is greatly appreciated. I will be in contact with Julie Shatto of the Buildi.ng Department to conf.um that you
have received this package and that we have satisfied your departments requirements for permit.
Sincerely,
Keith Ballantyne,

Provide contours or sufficient spot elevations to check site
grades. One-percent is the minimum requirement without special
construction requirements by a licensed engineer.
All plans submitted to this department are required to have a
professional engineer's stamp or registered architects stamp by
state law. Architect stamp must include a signature and date.
Professional Engineer stamps must include the current seal and
expiration date as well as signature and date.
The County requires a Spokane County Type 4 drywell lid for
drywells in 208 swales. Specify on the drawings this type of lid.

A licensed surveyor hired by the owner or contractor will check the curb forms
for all grades less than 1.0% before pouring concrete.
Spokane County will water test all curb and gutter for proper drainage.
Any curb and gutter which does not drain properly will be removed and
replaced at owners expense until proper drainage is achieved.

Enclosed please find resubmittal to address yaur review comments an the above named project, We
have number.ed your comxnents for easc i'n. rcferral. You may recall we discussed this praject on the
phane several, weeks ag;o.
1_ The ericlosed improvemenfl plan has been revised to reflect fhe total frontage of the affected
parcels. The grade spreadsheet has also been revised accaxd.i.nglY-
2. A taper lengtli of 25 feet seor-ns to be more suitable £or atr.ansxtion w,i,cit;h o#' 2.00 feet and wpuld
present less of a problem in constructing athin sliver of pavement at the naarrow end.
3_ rme enclosed revised impravernent, plan haS bEen amended t0 indicate the Iocatzons and sizes qf
new approaches to he constructed. 7nformation was received from Bernarda-Wills Architects.
4. We have added a column to the grade spreadsheet to emphasize the deviation from the desired
range afcross slopes (2.0% ta 4.5°lo). As you can see, one of the stations identified as being
nutside the s~~e6fi-cations is 0.0245' out af tolexance, with the balance kreing 0.0129' ar'less. We
have a.lso revised the last station to reflect the plan change (sce 41 above).
5. P].ease see the enca.osed aeevIsed improvement plan.

Re: SR-27 Spec Office Bldg. (ZE-89-85)
Dear Ms. Shatto:
After reviewing the above development which is located adjacent to the Pines Road (SR-
27)/I-90 Interchange, the Washington State Department of Transportation (WSDOT) has
the following comments concerning this proposal:
1. WSDOT requests that the County require the proponent to prepare the needed
supplemental SEPA documentation to address the substantial change in traffic
conditions at this interchange that have occurred since this zone change in 1985. Zt is the opinion of WSDOT that this interchange will be at capacity once the
' developments that are already under construction are built out. In addition to these problems at the interchange area, the intersection of Pines Road and Mission
Avenue' has also experienced one of the highest intersection accident rates for
signa(ized intersections in our district. It is because of this lack of capacity to safely
accommodate additional traffic that we request that this development not go
forward until it can be demonstrated thru SEPA that adequate facilities exist to
accommodate this develop►nent.
2. To address these SEPA concerns WSDOT requests that the applicant conduct a
traffic analysis for the Pines Road/I-90 Interchange area anci for the intersection of
Pines Road and Mission Avenue. This traffic analysis needs to addr-ess the elements
shown in the attached "Traffic Study Requirements" form. The applicant should
also be aware that Spokane County Engineers may have additional requirements as
the above only addresses WSDOT's concerns.
3. Because of the above issues WSDOT requests that a sign off block be provided to

Re: Pines Road Development
Dear Mr. Davis: .
After receiving your February 7, 1994 letter on the E. 12111 Mission Restaurantlretail
- ' development, we are somewhat puzzled and dismayed by your response. To simply say
that there is no significant new information available is a statement we strongly disagree
with. In our January 24, 19941etter we pointed out areas where there is significant new
infonnation availabte. The original SEPA documentation was prepared in 1981 and was
. subsequently revised in 1985. To say no new information is available and the existing 9
year old SEPA is adequate is unacceptable to us, as the following new informdtion is available.
1, This particular area has experienced very rapid growth in the last 13 years. As a
result of this rapid traffic growth the traffic impacts this development will have on
Pines Road and the I-90 Interchange will have significantly changed and need to be
addressed. 7he following is a summary of traffic growth in this area:

Febcuary 17, 1994 .
Pagc 2 2, The intersection at Pines and Mission has been experiencing one of the highest
intersection accident rates of any signalized intersection in our district. This is a
definite safety concern to us and the county.. This is a significant pTOblem that needs
to be addressed, as this development will add additional traffic to this intersection .
fi,rther aggravating this condition. This was not even previously ntentioned in the
existing' SEPA. We have also attached a summary of this accident data for your
information.
. 3 A fecent traffic study conducted fot an apartment complex on the north side of the '
Pines Road Interchange has identified significani capacity deficiencies in this
interchange area. This interchange area will be further impacted by ihis development
as the existing SEPA checklist identifies Pines and I-90 as routes that traffic from this
development will use. Since the background traffic volumes have significantly
changed since 1985, the impacts this development will have on the interchange will
have also significantjy changed. Attached is a summary letter from this traffic study.
. 4. Air quality conformity should be addressed under thc new SEPA as this was not done
in the present SEPA.
Because of these above mentioned significant changes since the existing SEPA ,
documentation was prepared, WSDOT requests that Spokane County readdress these
probable impacts in the form of a trafTc study for this development. If after reviewing this
material it still is the position of Spokane County not to open SL-PA on this development
we would like to know your reasons for doing so along with what traf~ic engineering
judgment that was used in determining that these impacts are not significant or why they
do not constitute new information. In addition to this, we would also like to -know if this
decision can be appealed and to whom -we would appeal it to. This would be vety helpful
in dealing with this and future developments which may fall into a similar situation.

RE: Lawson/Gunning Rezone (SR-27)
Dear Mr. Trepanier:
This letter has been written in response to your request for
further information aB outlined in the letter of July 13, 1993.
The information you asked for Was an analysis of the intersection
oP Indiana and Pines including the R.A. Hanson/Price Development
and the HCS data which led to the levels of service calculated in
the TIA.
The Everqreen Interchange report, an official WSD4T document, was
used to generate the traffic volumes associated with the
Kanson/Price Development. Volume data was only available for the
PM peak hour, so we reanalyzed only the PM peak hour. That report
was based on the assumption that creating an Evergreen Interchange
will lower traff ic on Pines Road. That assumption was carried
through the analyais done in this letter; thus, the through volumes
on Pines Road are lower than in the TIA previously eubmitted to
you.
An additional assumption was made for the analysis of Indiana and
Pines with the Lawson/Gunning project in p1acE. Due to the
addition of the Evergreen Interchange, it was assumed that all of
the weetbound off ramp traffic would use Evergreen, and thus would
not use this intersection.
Existinq geometric conditions at Indiana & Pines Road are
inadequate to handle the traffic projected in the Evergraen
Interchange report, =egardless og whether the Lawson/Gunning
project is rezoned. To brinq this intersection to a Level of
Service D xiil require an extra left turn lane and a dedicated
right turn lane for southbound Pines Road. Northbound Pines Road
. will require two dedicated riqht turn lanes. Westbound Indfana
will also requfre two dedicated left turn lanes. Adding the
traf f ic generated by the LaWSOn/Gunning project will not af fect the
Level of Service of aither the improved on unimproved intersection.

NORTH'~dVEST CORNER OF MISSION AND PINES
Project Description:
This project is a commercial development of 3.6 acres. It includes one retail building,
one offce building and one future pad site. The project is on the west side of Pines
Road, north of Mission Avenue. The site was previously unoccupied.
Methodology:
The procedures as outlined in "Guidelines for Stormwater Management" as published by
Spokane County Engineers was followed. The rational method is used with a 10 year
return frequency for on site drainage. No off site drainage flows onto the site.
Soils: (See map, Attachment "A
Soils are classiied as GgA - Garrison Gravelly Loam in accordance with the "Soil
Survey, Spokane County Washington, 1968".
GgA - 0 to 5 percent slopes. Gravelly, medium-textured, somewhat excessively drained
- soils formed in gravelly glacial outwash material from a variety of acid, igneous
parent rock; on nearly level to moderately sloping terraces; depth to mixture of
sand, gravel, and cobblestones ranges from 2 1/2 to 5 feet. This soil group is
acceptable for drywells per the GSM.
Topographic Data: (See map, Attachment "B")
The site generally slopes to the north with grades varying from 1% to 5%.
Demographic Data:
The site is currently unoccupied. Upon completion this site will contain a retail building,
an office building and a future pad site.
Drainage Report, Northwest Corner of Mission and Pines Page 1
September 7, 1994
Rainfall Data:
- Data used is in accordance with Figure 2, page 6-3 of the "Guidelines for Stormwater
Management", by Spokane County Engineers. A 10 year return frequency event was
used. This chart is included with the calculations of this report.
Methods of Runoff Control:
Control will be by four drainage basins which flow overland to grass percolation areas
(GPA's) and drywells located in the landscaped areas of the site. Roof areas will be
piped directly to drywells. All GPA's will be sodded for treatment.
Methods of Disposal:
Four (4) grass percolation areas, one for each drainage basin, will be utilized. All
swales contain one (1) each Spokane County Standard single depth drywell. Swales and
drywell capacities were sized using the 10 year on-site storm.
Peak Flow, Volume and Disposal Calculations:
a. Hydrology Computations:
The site has been divided into four (4) basins labeled alphabetically.
' o Basin A lies on the western side of the site and includes parking and sidewalk
areas around north and east sides of the retail building and landscaped areas along
the west and north.
o Basin B is just east of Basin A and contains parking, sidewalk and landscapes
areas in front of the office building.
o Basin C lies just east of Basin B and contains the same surface types as Basin
B, but sits in front of the future pad site.
o Basin D, lying east of Basin C and the future pad site, contains parking and
landscaped areas. All basins flow overland and deposit directly into the GPA's
for disposal. (See attached calculations).
Hydrology calculations were also performed on the roof areas. The retail
building roof generated 0.95 cfs and is disposed of by one (1) double depth
drywell. The office building roof generated 0.44 cfs and is disposed of by two
(2) single depth drywells. Flows were estimated for the future pad site assuming
a conservative 10730 sf roof would generate 0.70 cfs and would require one (1)
double depth drywell for disposal. The drywell and piping to the future pad site
will be installed with this development for future connection.
Drainage Report, Northwest Corner of Mission and Pines Page 2
September 7, 1994
b. Inlet Capacities:
Three (3) curb inlets are utilized with this design, two in Basin B and one in
Basin C. Individual calculations for each inlet show that widths of two (2) feet
will sufficiently pass the generated flow. Curb inlets are located at the low spot
of each basin area and any flow surpassing the capacity of the inlet will flow over
the curb and still flow to the GPA's.
c. Detention/Retention Storage Capacities:
Grassed percolation areas were calculated to hold the first 1/2" of runoff over the
entire parking lot area. See Calculations on the following pages. Grass
percolation areas are a minimum of 6 inches deep and will be sodded.
d. Pipe System Capacities:
Pipe diameters were calculated to handle each roof basins peak runoff for a 10
year storm event. Connecting to the building roof drains just outside the
building, runoff is routed to collection pipes for conveyance to the drywells.
Piping was designed for the retail and office buildings only. Each building
required a small closed conduit system which did not appear to warrant back
water calculations. Manning's equation was used to size roof drain piping and
- velocities of greater than 4 feet per second were maintained throughout. All
pipes are sized conservatively, with capacities well above the calculated 10 year
storm flow rates.
A roof schematic for each building and sizing information can be found on the
attached pages.
Remarks:
The above described system of stormwater control will provide the quality and quantity
controls as outlined in the "Spokane County Stormwater Management Guide" for the
Northwest corner of Mission and Pines.

Re: Wolff Center at Mission & Pin.es p
(Amendment to Project # 94006) 44NNING~
Dear Bill:
The Wolff Center is an addition to an existing development located at the Northwest corner of
Mission and Pines. The attached plan shows grading to accommodate a new office building
and drive-through. The civil site work for the existing development was designed by our
office in 1994 and reviewed and approved by Paul Lennemann. This letter and attached
information is intended to be an amendment to the original drainage report and the original
grading and drainage plan.
Drainage Basin "A" originally required 1066 square feet of swale area and one single depth
dcywtll for drainage disposal. The drywell was installed as required, however the swale area
shown on our original drawing and constructed in the field, had a bottom area of 2700 square
feet. Revised calculations which include the new drive-through area, show that the existing
swale and drywell are adequate to dispose of the additional drainage created by the drive-
through. No additional drainage work is required for this development. Revised calculations
are attached.
All other elements of the development were built with the original construction or are the same
as designed previously. Roof drainage for the Wolff Center building was designed with the
original development and will not change.
Please feel free to call if you have any questions or concerns.
Sincerely,
T YLOR ENGINEERING, INC.
