Re: Washington VOA Housing, County ReF. No. B93106
. Information required for Permit
Dear Bob: The E'aulsen ("enter
Suite 860
Enclosed are copies of the site plan and road improvement plans for the Washington
VOA Housing complex. Once we havc obtained the necessary bonds, easements, etc., we
will bc; submitting to the County for a building permit. Your pre-application review
comnzei:ts of 8-9-93 identified some of the following reqctirements. Our questinns are: 1'lest 421
Item C)l.a 'prior to release of a building pennit...financial gzcaranry in an ainount estimated Riverside '
by the Cout:ty Eligineer to cover the cost of constnection or improvemerits shall be filed witli SPflhane
the County Engineer." Please provide the County estimate and information which ~IA 99201
explains the desired format for the guarAnty.
Item 02. 'Applicait shall dedicate GO feet for the e.xtension of Tl'iird avenue through the ~
project for right-of-way. Enclosed is a copy of the legal descriptions which were written +
and filed by Adams and Clark, when the larger piece of property was subdivided into i 509 456 8236
rivo parcels. Is anything amiss here?
Item 03. "Please submit a copy of a recorded proper)deed fran the Auditor's ojfice...cepolz 309 7,17 0570
receipt of the deed our staff will prepare the riglzt of way deed." See item C)2. above. ]s
this the right of way deed you are referring to? k-11, item C)4. 'ApproacJt pennits must be obtained after a site nla,: l:as heen approved, and before the issuaitce of a buildingpermit..." Does this mean we submit fnr building permit,
wait until the Planning department signs oft; and then ask the Contractor to obtain the -
approach permits? ~ ~I~~A~ r~t 4r ~e
1 ~
Item Ulb. ":..a strip of property 30 feet in width...shall be set aside in reserve." The Planning
Department has stipulated certain landscaping limitations, etc. for this area. Is there
anything the Engineering Department can require in the way of deed revisions,
easements, etc. at this -time? VO ~ ~ ~ ~ ~ ~r' `
~
Manap-erial Repuirements Dean Logsdon h s indicated that we will probably be '
required to provide an easement for the road drainage. Does this also apply to the
property at the south, which is owned by another party? Does your office write the easements? Iiow are the easements put intn effect? I have this idea that lawyers do_ all ~
of this legal stuff, but VOA's attorney says it isn't so.
Please get back Nvith us as soon as possible. VOA National is a large organization, and it , - ;
wiU take a long time for them to respond, once wE get information to them. Thanks for
all of your help.

Dear Bob :
Enclosed is a revised Grading and Drainage Plan for the
above referenced proj ect, which was submitted for building
permit review on 6/7 / 94 Although we have not yet received
written review caraunents fram your office, we did receive
a call from you saying that drainage calculations we-re needed. Upon re~iewing our work, the Civil En;ineer determined certain
changes which would be needed and revised-the nlan accordingly.
Hopefully, these changes anticipate all of your review letter
RECEIVED comments. Before we go to the considerable trouble of revising
all the other site plans affected by the change, we would like
JVN 2 21994 to know that the approach shown on this revised plan of 6-21-94
SPORANE CQUNTYENGINEER is basically correct. Please call as soon as poss-ible so that
we don't. hold up the re-,~iews of any of the other department.s.
509 456 8236 Thank s.

DRAINAGE REPORT
FOR
THE SCROGGIN APARTMENTS
PROJECT DESCRIPTION
The project is a.34 acre parcel of land located in Tract 182 of Opportunity Tracts
which will be developed into 6-unit apartments. The project is located on Third
Avenue, approximately 660 feet east of Pines Road and is in Section 22, Township
25 North, Range 44 E.W.M.
SOILS
In accordance with the "Soil Survev of Saokane Countv. WashinQton, 1968", the soils
are identified and categorized as (see Figure No. 1):
"GgA - Garrison gravelly loam, 0 to 5%; 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."
This soil group, Garrison, is classified Type "B" soil as per Technical Release 55 and
approved for drywell use as in the "Guidelines for Stormwater Management".
TOPOGRAPHIC DATA
The project is located on the Spokane Valley floor adjacent and south of Third
Avenue. The site slopes vary between flat (east/west) and 3% (north/south).
DRAINAGE BASIN DATA
The project has one drainage basin. The basin consists of the south 1/2 of Third
Avenue and the proposed apartment project. There is no off-site runoff entering the
site as the south side of the property is the high point between 3rd and 4th Avenue.
A grassed swale and single-depth drywell are provided to control and dispose of the
runoff.
Runoff from the building's roof and half of the west garage roof will be collected by
gutters and piped to the swale. Runoff from the parking lot will be by sheet flow,
collected at the low point and piped to the swale. All other runoff will be collected
through sheet flow across the site.
SCROGGIN APARTMENTS 1 6/18184
The drywell, curb and gutter, sidewalk and Third Avenue are approved improvements
from the Washington Apartments 693106 project. The proposed project will expand
the swale to accommodate the required "208" storage and additional 10-year storm
volume generated by the Scroggin Apartment project.
RAINFALL DATA
Data used is in accordance with Figure 2, page 6-3 of the "Guidelin'es for Stormwater
Management", by Spokane County Engineers. A 10-year return frequency event is
used since the basins do not receive off-site runoff.
METHODS OF DISPOSAL
Drywells will be utilized for disposal. The grate elevation will be installed six inches
above the bottom of the grassed swale to provide for "208" storage. Grate inlet and
drywell capacity calculations are provided in Appendix A.
PEAK FLOW, VOLUME AND DISPOSAL CALCULATIONS
A. Hvdroloav Comoutations
The grassed percolation swale was sized to accommodate 1/2 inch of runoff
from required impervious areas within the basin. The swales are designed to
provide a 6" retention depth to allow infiltration and treatment of the collected
runoff.
Drywells were sized to handle the 10-year runoff flow within the project
drainage basin. The Bowstring method was used to analyze the runoff in
determining numbers and size of drywells. Bowstring computation results are
attached in Appendix A.
B. Inlet CaQacities
A Spokane County Standard grate Type "4" will be used on the drywell. Inlet
capacities are calculated to be 1.6 CFS for a flow depth of .2 feet and 2.26 cfs
for a flow depth of .25 feet. See calculations in Appendix A.
A Spokane County Standard grate Type "2" will be used on the catch basin in
the parking lot. Grate capacities are calculated to be 0.83 cfs for a flow depth
of .14 feet. See calculations in Appendix A.
SCROGGIN APARTMENTS 2 6118/84
CONCLUSIONS
The stormwater system described below will provide the necessary runoff controls,
as outlined in the "Spokane County Stormwater Management Guide", for Scroggin
Apartments.
1. One grassed 208 swale with a volume capacity of 419 cf, a bottom area of ,
838 square feet, and a storage depth of 6 inches.
2. One County Standard, Type A drywell installed in the bottom of the swale with
a County Standard Type 4 grate installed on the drywell 6 inches above the
elevation of the swale bottom.

CALCULATIONS
The Basin and Inlet Calculation section is arranged so that the basin is analyzed for Peak Q followed
by the parking lot sub-basin for flow to the grate. The Type 4 and Type 2 grate inlet calculations
follow the basin calculations.

CALCULATIONS
The Basin and Inlet Calculation section is arranged so that the basin is analyzed for Peak Q followed
by the parking lot sub-basin for flow to the grate. The Type 4 and Type 2 grate inlet calculations
follow the basin calculations.

DRAINAGE REPORT
FOR
THE SCROGGIN APARTMENTS
PROJECT DESCRIPTION
The project is a.34 acre parcel of land located in Tract 182 of Opportunity Tracts
which will be developed into 6-unit apartments. The project is located on Third
Avenue, approximately 660 feet east of Pines Road and is in Section 22, Township
25 North, Range 44 E.W.M.
SOILS
In accordance with the "Soil Survev of SDokane Countv. Washinaton, 1968", the soils
are identified and categorized as (see Figure No. 1):
"GgA - Garrison gravelly loam, 0 to 5%; 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."
This soil group, Garrison, is classified Type "B" soil as per Technical Release 55 and
approved for drywell use as in the "Guidelines for Stormwater Management".
TOPOGRAPHIC DATA
The project is located on the Spokane Valley floor adjacent and south of Third
Avenue. The site slopes vary between flat (east/west) and 3% (north/south).
DRAINAGE BASIN DATA
The project has one drainage basin. The basin consists of the south 1/2 of Third
Avenue and the proposed apartment project. There is no off-site runoff entering the
site as the south side of the property is the high point between 3rd and 4th Avenue.
A grassed swale and single-depth drywell are provided to control and dispose of the
runoff.
Runoff from the building's roof and half of the west garage roof will be collected by
gutters and piped to the swale. Runoff from the parking lot will be by sheet flow,
collected at the low point and piped to the swale. All other runoff will be collected
through sheet flow across the site.
SCROGGIN APARTMENTS 1 8/18/84
The drywell, curb and gutter, sidewalk and Third Avenue are approved improvements
from the Washington Apartments B93106 project. The proposed project will expand
the swale to accommodate the required "208" storage and additional 10-year storm
volume generated by the Scroggin Apartment project.
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 do not receive off-site runoff.
METHODS OF DISPOSAL
Drywells will be utilized for disposal. The grate elevation will be installed six inches
above the bottom of the grassed swale to provide for "208" storage. Grate inlet and
drywell capacity calculations are provided in Appendix A. PEAK FLOW, VOLUME AND DISPOSAL CALCULATIONS
A. Hvdrolo4v ComQutations
The grassed percolation swale was sized to accommodate 1/2 inch of runoff
from required impervious areas within the basin. The swales are designed to
provide a 6" retention depth to allow infiltration and treatment of the collected
runoff.
Drywells were sized to handle the 10-year runoff flow within the project
drainage basin. The Bowstring method was used to analyze the runoff in
determining numbers and size of drywells. Bowstring computation results are
attached in Appendix A.
B. Inlet CaQacities A Spokane County Standard grate Type "4" will be used on the drywell. Inlet
capacities are calculated to be 1.6 CFS for a flow depth of .2 feet and 2.26 cfs
for a flow depth of .25 feet. See calculations in Appendix A.
A Spokane County Standard grate Type "2" will be used on the catch basin in
the parking lot. Grate capacities are calculated to be 0.83 cfs for a flow depth
of .14 feet. See calculations in Appendix A.
SCROGGIN APARTMENTS 2 6/18/94
CONCLUSIONS
The stormwater system described below will provide the necessary runoff controls,
as outlined in the "Spokane County Stormwater Management Guide", for Scroggin
Apartments.
1. One grassed 208 swale with a volume capacity of 419 cf, a bottom area of
838 square feet, and a storage depth of 6 inches.
2. One County Standard, Type A drywell installed in the bottom of the swale with
a County Standard Type 4 grate installed on the drywell 6 inches above the
elevation of the swale bottom.

CALCULATIONS
The Basin and Inlet Calculation section is arranged so that the basin is analyzed for Peak Q followed
by the parking lot sub-basin for flow to the grate. The Type 4 and Type 2 grate inlet calculations
follow the basin calculations.

SPOKANE COUNTY AIR POLLUTION CONTROL AUTHORITY
1. Air pollution regulations require that dust emissions during demolition, constniction
and excavation projects be controlled. This may require use of water sprays, tarps,
sprinklers or suspension of acrivity during certain weather conditions. Haul roads
should be treated and emissions from the transfer of earthen material must be
conmolled as well as emissions from all other construction related activities. .
2. All travelled surfaces need to be paved and kept clean. If traclang or spills occur on
paved surfaces, measures must be taken immediately to clean these surfaces.
3. Debris generated as a result of this prnject must be disposed of by means other than
burning.
4. Solid fuel heating device regulations must be met It now appears that any plat that
' has more than one solid fuel heating device per acre has the potential to violate the
air quality standards for PM10 (fine particulate matter). Possible mitigating
measures should be addressed in any plat with more than one solid fuel heating
device per acre. Such mitigating measures might include such things as limiting the
number of devices to less than onelacre, using of only "certified" devices, gas logs
in fireplaces, etc.

PROJECT DESCRIPTION
The project is a.34 acre parcel of land located in Tract 182 of Opportunity Tracts
which will be developed into 6-unit apartments. The project is located on Third
Avenue, approximately 660 feet east of Pines Road and is in Section 22, Township
25 North, Range 44 E.W.M.
SOILS
In accordance with the "Soil Survev of Spokane Countv, Washinaton, 1968", the soils
are identified and categorized as (see Figure No. 1):
"GgA - Garrison gravelly loam, 0 to 5%; 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."
This soil group, Garrison, is classified Type "B" soil as per Technical Release 55 and
approved for drywell use as in the "Guidelines for Stormwater Management".
TOPOGRAPHIC DATA
The project is located on the Spokane Valley floor adjacent and south of Third
Avenue. The site slopes vary between flat (east/west) and 3% (north/south).
DRAINAGE BASIN DATA
The project has one drainage basin. The basin consists of the south 1/2 of Third
Avenue and the proposed apartment project. There is no off-site runoff entering the
site as the south side of the property is the high point between 3rd and 4th Avenue.
A grassed swale and single-depth drywell are provided to control and dispose of the
runoff.
Runoff from the building's roof and half of the west garage roof will be collected by
gutters and piped to the swale. Runoff from the parking lot will be by sheet flow, ,
collected at the low point and piped to the swale. All other runoff will be collected
through sheet flow across the site.
SCROGGIN APARTMENTS 1 6/16/84
The drywell, curb and gutter, sidewaik and Third Avenue are approved improvements
from the Washington Apartments B93106 project. The proposed project will expand
the swale to accommodate the required "208" storage and additional 10-year storm
volume generated by the Scroggin Apartment project.
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 do not receive off-site runoff.
METHODS OF DISPOSAL .
Drywells will be utilized for disposal. The grate elevation will be installed six inches
above the bottom of the grassed swale to provide for "208" storage. Grate inlet and
drywell capacity calculations are provided in Appendix A.
PEAK FLOW, VOLUME AND DISPOSAL CALCULATIONS
A. Hvdroloav Computations
The grassed percolation swale was sized to accommodate 1/2 inch of runoff
from required impervious areas within the basin. The swales are designed to
provide a 6" retention depth to allow infiltration and treatment of the collected
runoff.
Drywells were sized to handle the 10-year runoff flow within the project
drainage basin. The Bowstring method was used to analyze the runoff in
determining numbers and size of drywells. Bowstring computation results are
attached in Appendix A.
B. Inlet Capacities
A Spokane County Standard grate Type "4" will be used on the drywell. Inlet
capacities are calculated to be 1.6 CFS for a flow depth of .2 feet and 2.26 cfs
for a flow depth of .25 feet. See calculations in Appendix A.
A Spokane County Standard grate Type "2" will be used on the catch basin in
the parking lot. Grate capacities are calculated to be 0.83 cfs for a flow depth
of .14 feet. See calculations in Appendix A.

CONCLUSIONS
The stormwater system described below will provide the necessary runoff controls,
as outlined in the "Spokane County Stormwater Management Guide", for Scroggin
Apartments.
1. One grassed 208 swale with a volume capacity of 419 cf, a bottom area of .
838 square feet, and a storage depth of 6 inches.
2. One County Standard, Type A drywell installed in the bottom of the swale with
a County Standard Type 4 grate installed on the drywell 6 inches above the
elevation of the swale bottom.
