Jackson Avenue and Montgomery Drive Drainage Calculations
As required as part of the conditions of approval for SP - 1147 - 97, a street widening of Montgomery
Drive and Jackson Avenue has been designed. Drainage calculations and assumptions made are as
follows.
Jackson Avenue
A predevelopment basin of approximately 5.6 acres current flows toward Jackson Avenue. This basin is
intercepted by Jackson Avenue with the drainage directed to a drywell located near the intersection of
Jackson and Montgomery. The predevelopment flow to this point was calculated to this point was
calculated to be 2.82 cfs. The calculation sheet is attached. The improvements that are proposed as part
of the Sonrise Place NiHP significantly intercept these flows (See submittal documents for MHP - 3-
97). Subsequently the amount of flow to the drywell referenced above is reduced to.72 cfs. This
calculation sheet is also attached.
Montgomery Drive
The existing section of roadway and design is a superelevated section with drainage directed to the
south or away from the subject property. Because of the small amount of widening (10 feet) and no
requirements for the opposite side of the roadway were required, no drainage calculations are provided
for this portion of roadway.
The design improvements shown in this set of plans and calculations conform to the applicable editions
of the Spokane County Sta.ndards for Road and Sewer Construction and the Spokane Co. Guidelines for
stormwater management. All design deviations have been approved by the Spokane County Engineer. I
approve these plans for construction.

This proposal is technically incomplete for the following reasons:
• There is a 208 pond partially located in the public right-of-way. This pond should be moved to be located
outside of Spokane county right-of-way.
The plans that were submitted did not meet the submittal requirements of Spokane County. They should be
revised and resubmitted with a submittal checklist.

I received the above referenced project application on June 19, 1997. The SCS Soils Map identifies this
area as being Garrison Gravely Loam soils. The soil survey in this area is known to be accurate.
Therefore, since this is an approved soil for stormwater disposal, no concept drainage plan is required.
We have no information that says there are any critical areas on this site.
The stormwater proposal proposes to put 208 ponds on parts of adjacent tracts and public right-of-way.
Two of the pond would encumber the northerly portion of the SP-1147-97, Tracts A,B, & C. easements
will be required for the pond that affect tracts A, B, & C. The 208 pond that is partly located in Spokane
County right-of-way needs to be moved onto the trailer court property.
I recommend using the standard drainage condition.
A fee agreement is required as we have received plans for review for streets and drainage.

commercial properties to the south and can be granted by the Short Plat. However, the N'viobile Home ~
Park will be held until the Short Plat is finalized.
9. A high volume, radius approach off Jackson will not be allowed. Please revise all plans to reflect a
residential driveway approach as sheet A-7.
10. The Mobile Home Park will not be able to be approved until the road plans are accepted. This

Z__
construction due t0 the operation of truck~ '1Rd E'c7u]p*t1t'nt ;?rlrl nnrnn;il n,oi<<-L-;
associated with construction activities.
Construction noise categories include road and utility development, site
preparation, and building construction. Earth-moving equipment which includes
compactors, backhoes, tractors, scrapers, graders, pavers, and trucks generate
noises ranging from 72 to 96 dbA (observed from a distance of 50 feet).
Materials handling equipment, including concrete mixers and concrete pumpti.
generate sounds ranging from 75 to 88 dbA. Pumps, generators, anc.l
compressors generate sounds ranging from 70 to 87 dbA, and jackhammers and
rock drills generate peak sounds of around 90 dbA. Once the major groundwork
is accomplished, including the digging of the foundations and footings for the
structures, the noise peaks that are generated will be directly related to the
erection of structures and landscaping activities. This would include hammering
and sawing as well as truck traffic which would be hauling supplies ar~'
materials. The maximum noise levels generated by these activities could ranL,:,
from 70 to 90 dbA. It should be noted that sounds originating from temporai:,
sites as a result of construction activity (which intrude on residential areas) ar-C
exempt from noise restrictions mandated by the Washington Administrative Cocie
(WAC). This is provided that these intrusions cio not ucctin cetwren thc hotirs
of 10:00 p.rn. ~in(l 7:()O
Following the wmpletion ut constructiun prujects, lung-term nuise impacts wuuli-i
occur due to increased traffic generated hy thc development and normal noiscs

as possible.
• Turning off idling equipment. • Limitation of construction hours to coincide with the normal workday period.
• Scheduling the noisiest operations near the middle of the day, and notifying
nearby residents whenever extremely noisy work will be occurring.
• The use of permanent or portable barriers around puint noise sources.
11. LIGHT AND GLARE
a. Exterior porch lights and private street lights will be visible in the evening and
nighttime hours. The lights from the homes and vehicles will be typical of
similar residential developments.
15. PUBLIC SERVICES
a. The addition of new homes and associated population could result in an increased
demand for fire and police protection. The development would not by itself
result in the need for additional manpower for provision of public services.
The proposed development is within the East Valley School District. The
children attending any of these schools would require busing.
The proposed development is served by Fire District No. 1.
b. Fire hydrants will be installed within the development to increase fire fighting
capabilities in the event of a fire. The private roads will be maintained year-
round to provide unobstructed access to the site for emergency vehicles.
Development and home building will be phased over several years, which will
mitigate direct impacts on schools and other service needs.
