at this time.
The attached comment list contains items of concern which we discovered during a cursory
review of this submittal. You should be certain, before you resubmit the plans and calculations
for this project, that your submittal meets the requirements of all applicable agencies. When the
olans are resubmitted, nlease mark all chanees on the revised print in color.
,
If you have any questions about this review, please contact Ed Parry at 456-3600. Thank you.

PROJECT P1788 . DATE: 6 June 96
PROJECT NAME: Adams Court
PROJECT DESIGN
3. Pavement calculations (whatever method was used to determine the section) were not included in this
submittal
4. The plans generally do not include the minimum plan and profile elements indicated in the Standards
& Guidelines for Stormwaxer Managemenr; e.g.: The Joyce Court CL profile was not included, CL
station/offset for the drywell & curb cut in the cul-de-sac was not indicated, MCR elevations at the cul-
de-sac were not indicated, cul-de-sac radii (pavement & easement limits) were not clearly indicated, info
copy of existing/proposed utility plan was not included, curb grade worksheet for street widening was
not included, CL bearings and/or distances on roads were not indicated, Section/Range/Township was
not indicated, Stationing equation at Joyce Lane/12th Avenue was not indicated, new paving limits on
12th Avenue (including tapers) were not indicated, private road easement/tract limits were not indicated
in private road section, pavement transition at Adams was not indicated, 0/R/L/T was not indicated on
curb radii, Datum/benchmark were not indicated, future acquisition on Adams was not indicated, etc.
5. Drainage calcs need to address developed condition flows discharged from this project to offsite
parcels 6. The basin map should be submitted as part of the drainage report. The basin limits indicated on the
road and drainage plans submitted did not indicate the limits of the basin served by the swale on 12th
Avenue, or the Tc path for that basin. Topographic contours need to be shown, and need to extend off
the site as far as is necessary to determine basin limits
9. The cover sheet of the calculations did not bear the certification statement, as required in the
S tandards
10. Standard notes (provided at pre-design meeting) were not included
11. Plans were not signed by the Developer

Pre-design conference; 208 & Sidewalks
You had questions about these items:
1. 208 volume for existing pavement.
Volume for water quality treatment should be provided for some
(preferably all) of the existing pavement draining to the
stormwater facilities on this site. The quantity of the existing
pavement to be treated would depend on the impacts to the site; as
much existing pavement should be treated as can be, without adding
so much area to the 208 swales that a significant negative impact
on the usage of the lots would result. Engineering judgement should
prevail.
2. Sidewalks on the north side of 12th Avenue.
The sidewalk required by the Conditions of Approval should be
provided. If you feel that there is adequate justification to
support a waiver of this requirement, then you could submit a
Design Deviation request for the County Engineer's consideration.
You should note that submission of a Design Deviation request
carries no guarantee of approval.
If you 4ve any further questions, please call me.

Standard Plan Notes for Developer Plan Submittals
1) All work and materials shall be in conformance with the "SPOKANE COUNTY STANDARDS FOR
ROAD AND SEWER CONSTRUCTION 1995", and as amended.
2) Locations of existing utilities shown in the plans are approximate. The Contractor shall be
responsible for locating all underground utilities. Any conflicting utilities shall be relocated prior
to construction of road and drainage facilities.
3) The Contractor is required to have a complete set of the approved road and drainage plans on the
job site whenever construction is in progress.
4) If the Contractor discovers any discrepancies between the plans and existing conditions encountered,
the Contractor shall immediately notify the Design Engineer and the Spokane County Engineer's
Office.
5) For construction of drywells, install filter fabric (Amoco 4545 or approved equivalent) between the
drywell barrel and the washed drainrock, and between the washed drainrock and the native soils.
6) Prior to site construction, the Contractor is responsible for locating underground utilities. Call the
underground utiliry location service at 456-8000 before you dig.
Optional Notes (when applicable to projectl
7) For any curb grades less than 0.8% (0.008 ft/ft), a Washington State-licensed Profe.ssional Land
Surveyor shall verify that the curb forms are at the grades noted on the approved plans, prior to
placement of curb material. The Contractor is responsible for arranging and coordinating work
with the Professional Land Surveyor.
8) The Contractor shall employ a Licensed Surveyor to verify that the cross-gutter forms are at the
correct plan grade and elevation prior to concrete placement. The cross-gutters shall be coastructed
prior to paving, and the pavement shall then match the edge ot the concrete cross-gutter
Use note #9 whenever '208' swales are used:
9) The floor of a 208 swale includes the level portion of the floor of the swale, and the sideslopes of
the swale up to the 208 overflow elevation or top of drywell. The soil located in the floor of a 208
swale shall be a medium to well-draining material, with a minimum infiltration rate of 0.5 inches
per hour. The Engineer shall provide a written statement which verifies that all '208' swales conform
to this requirement. This written statement shall be submitted to the Spokane County Engineer's
Office prior to installing finished landscaping/sod and prior to final acceptance. The swale floor
material shall be installed to a native soil stratum which also meets or exceeds this minimum
percolatioa rate of 0.5 inches per hour
Standard Ero,si,nn Control Notes
These notes are to be included an the p1an set when erosion control facilities are required and incorporated
inta the plans.
ER1) An Erosion/Sedirnentation Cantro1 (ESQ plan is required far this prajeet. Irnplementatiqn of the
ESC pian, aLnd cvnstruction, maintenance, and upgrading of tlae ESC facilities are the res~onsxbility
vf the Developer until ail constructio❑ is campleted and accepted by Spokane County, ar until
vegetation is estaalished throughaut the site, and accepted by Spokane Cou,nty, whichever is later.
ER2) Approeral of the E5C pla.n does not constitute approval of any af the proposed road, storm drai,nage,
grading or utility design elements shown on the ESC plan.
ER3} The erasionlsedimentation control measures shawn are the rninimum requirements for the anticipated
site conditions. The Contractor shail inspecz and maintain these ESC measures daily, and shall
rn,aintain and upgrade these measures a.s necessary to prevent sediment-laden waier frvm eith&
flowing off the site, or into new/existing storm drainage facilities, such as drywelis, culverts, or
gravel galleries.
ER4} The Contractorlr7eae loper is respansibie far installing Rack Canstruction Entries at any and, all
locations used to enter or exit the praject site. .
