RE: Drainage Report of the Itron Facility
ATTN: Mr. Gary Nelson, P.E.
Gentlemen:
Fnclosed is the Itron Site Drainage including a grading plan and calculations for the
on-site grass percolation areas, drainage basins, and inlet requirements. Procedures
used are as outlined in the "Guidelines for Stormwater Management" published by
Spokane County Engineers with corrections as of 4-15-86.
Our drainage plan is for the final parking lot areas. As this project is proceeding
witih a rapid schedule, with desired construction beginning immediately, a prompt
review would be greatly appreciated.
Following your review, I would be happy to answer any further questions you may
have regarding this report.
Sincerely,
TAYLOR ENGINEERING, INC.

• Drainage Report
For the New Itron Facility
Project Description:
The New Itron I'acility is an expansion on the existing facility located at
Spokane Industrial Park. The existing site is east of Sullivan Road between
existing Euclid Avenue and Marietta Avenue.
This report is an adclition to our September 24, 1990 drainage report, and
pertains to the new development located north, east and west of the existing
facility. '
The parking areas, clriveways, and a majority of the lawns for this portion,
will be drained by overland flow to new grass percolation areas as d.iscussed in
the following pages.
Soils:
In accordance with "Soil Survev, Spokane Countv, WashinQ►ton, 1968" the soil
is identified and categorized as:
GgA - Garrison gravelly loam, classified as gravelly, medium textures,
somewhat excessively drained soils formed in gravelly glacial deposits.
GnB - Garrison very stony loam, classified as gravelly, medium textures,
somewhat excessively drained soils formed in gravelly glacial deposits.
These soils are Type "B" soils as classified in the "Guidelines for Stormwater
Management".
Topp~raphic Data:
The existing site slopES to the north at about a 2% raw overall grade. The
proposed site drainage now flows within parking lot areas to 208 swales and
witl1in land.scape areas to drywells.
Demoerraphic Data: - The proposed site as it exists presently is landscaped and parking area. The
purposed and future, new parking area will provide approximately 374 spaces.
Rainfall Data:
Data used is in accordance with Figure 2, page 6-3 of the "Guidelines for
Stormwater Management", by Spokane Counl;y Engineers. A 10 year return
frequency event is used since the basins are contained within the site.

Methods of Runoff Control:
. Runoff control of the new development is by overland flow into new grassed
, percolation areas with overflow into drywells. Landscape areas will be
dra.ined into drywells without "208" swales. Grass percolation areas are
anticipated to be sodded for erosion control following construction.
Methods of Disposal:
Disposal will be by single or double depth drywells. They shall be Spokane
County Standard Type "A" and "B", as called out on the plans with standard
grates. Inlet capacity calculations are shown on sheet 22.
'Peak Flowt Volume, and Disposal Calculation:
a. Hydrology Computations:
The grassed percolation "208" areas were sized to accommodate
1/2-inch of runofr from all irnpervious and pervious surfaces within the
site. The impervious surfaces accounted for included the proposed new
parking areas.
The site was divided into 8 basins, "G" through "N", basins "A" through
"F" were used for our September 24, 1990 report. Drywells were sized
to hanclle the total runoff flow in their respective basins. Basin "]3"
from our previous report was enlarged to accommodate additional flow
from this phase. In adclition, to complete final drainage for all proposed
_ future construction, runoff from proposed roofs was calculated and
should be incorporated into their design. The Bowstring method was
used to analyze the runoff in determining numbers and size of drywells.
See calculations on sheets 4 through 21.
The roofing for the new manufacturing building is anticipated to be
synthetic material resulting in drainage routing directly to drywell.
Calculations are shown on sheets 22 through 24.
b. Inlet Capacities:
A spokane County Standard gratie will be used of all drywells. Inlet
capacities are calculated to be 1.6 CFS for a flow depth of .2 feet. See
calculations on sheet 25.
Portions of the parking areas will be installed with Spokane County
Standard Type "A" curbs. A 2.5' curb cut will be required at the low
points. Calculations are shown on sheet 20.

Drainage Report
For the New Itron Facility
Project Description:
The New Itron Facility is an expansion on the existing facility located at
Spokane Inclustrial Park. The existing site is east of Sullivan R.oad between
existing Euclid Avenue and Marietta Avenue.
7'his report is an adclition to our September 24, 1990 drainage report, and
pertains to the new development located north, east and westi of the existing
facility. '
The parking areas, driveways, and a majority of the lawns for this portion,
will be drained by overland flow to new grass percolation areas as discussed in
the following pages.
Soils:
In accordance with "Soil Survev, Spokane Countv, Washinaton, 1968" the soil
is identified and categorized as:
GgA - Garrison gravelly loam, classified as gravelly, medium textures,
, somewhat excessively clrained soils formed in gravelly glacial deposits.
GnI3 - Garrison very stony loam, classified as gravelly, medium textures,
somewhat excessively drained soils formed in gravelly glacial deposits.
These soils are Type "B" soils as classified in the "Guidelines for Stormwater
Management".
Top2graphic Data: .
The existing site slopes to the north at about a 2% raw overall grade. The
pro-)osed site drainage now flows within parking lot areas to 208 swales and
wit lin landscape areas to drywells.
DemoEraphic Data: The proposed site as it Exists presently is landscaped and parking area. The
purposed and future, new paxking area will provide approximately 374 spaces.
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 is used since the basins are contained within the site.

Methods of Runoff Control:
Runoff control of the new development is by overland flow into new grassed
percolation areas witih overflow into dxywells. Landscape areas will be
drained into drywells without "208" swales. Grass percolation areas are
anticipated to be sodded for erosion control following construction.
Methods of Disposal:
Disposal will be by single or double depth drywells. They shall be Spokane
County Standard Type "A" and "B", as called out on the plans with standard
grates. Inlet capacity calculations are shown on sheet 22.
,
Peak Flow, Volume, and Disposal Calculation:
a. Hydrology Computations:
The grassed percolation "208" areas were sized to accommodate
1l2-inch of runoff from all impervious and pervious surfaces within the
site. The impervious surfaces accounted for included the proposed new
parking areas.
'I'he site was divided into 8 basins, "G" through "N", basins "A" through
"F" were used for our September 24, 1990 report. Drywells were sized
to handle the total runoff flow in their respective basins. Basiri "B"
from our previous report was enlarged to accommodate additional flow
from this phase. In addition, to complete final drainage for all proposed
future construction, runoff from proposed roofs was calculated and
should be incorporated into their design. The Bowstring method was
used to analyze the runoi'f in detiermining numbers and size of drywells.
See calculations on sheets 4 ttirough 21.
7'he roofing for the new manufacturing building is anticipated to be
synthetic rnaterial resulting in drainage routing directly to drywell.
Calculations are shown on sheets 22 through 24.
. b. Inleti Capacities:
A spokane County Standard grate will be used of all drywells. Inlet
capacities are calculated to be 1.6 CFS for aflow depth of .2 feet. See
calculations on sheet 25.
Portions oF the parking areas will be installed with Spokane County
Standard Type "A" curbs. A 2.5' curb cut will be required at the low
points. Calculations are shown on sheet 20.

c. Detention/R,etention Storage Capacities:
Grass percolation areas were calculated to hold the first 1/2-inch of
runoff generated by all the impervious surfaces within the site limits.
In all cases the area provided will be larger than required.
Listed below are basins together with the swale volume required and
the volume provided:

Remarks:
The above described system o£ stormwater control will provide the necessary
quantity and qualil;y controls, as outilined in the "Spokane County Stormwater
Mariagement Guide", for Lhe parking areas.
