found items which do not appear to meet the minimum standards of the Sookane Countv
Standards for Road and Sewer Construction. We are, therefore, unable to accept your submittal
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
vlans are resubmitted. vlease mark all chanLyes on the revised print in color.
If you have any questions about this review, please contact Ed Parry at 456-3600. Thank you.
Very truly yours,

PROJECT NAME: Riverwalk 7th Addition
N.B.: Since this project is governed by the edition of the Spokane County Standards for Road and
Sewer Construction (the "Standards", adopted 2 May 95, with an effective date of 15 May 95), these
comments are general in nature, and do not represent a listing of all items which may not be in
compliance with the Standards. The responsibility for ensuring compliance with the Standards lies solely
with the Sponsor's Design Engineer. ALL DISCREPANCIES MUST BE ADDRESSED AND
RESOLVED PRIOR TO PLAN ACCEPTANCE
PRUJECT DESIGN
3. Calcs for the Mission Avenue pavement section were not included in this submittal.
4. Pipe profiles were not included in this submittal
5. Project overlay on the soils map obscures the underlying soil type. Pipe flow in supercritical regime
(Froude Number > 1) needs an energy gradeline analysis to confirm the pipe sizing
6. The existing topographic contours were not very clear. Tc paths could be shown more clearly,
perhaps with a different linetype & labeling. Basin limits on Mission Avenue do not correlate with the
high points shown on the curb profile elevations
8. The proposed section for Mission Avenue (IPEC's 29 May 96 letter) does not match either with the
Special Section provided to IPEC, nor with the section constructed in phase 1. As Todd Whipple noted
in a 4 Jun 96 telephone conversation with Ed Parry, the section constructed in phase 1(a contiguous
sidewalk) is obviously not in conformance to the approved plans for phase 1. As we discussed in our
pre-design conference, a request for Design Deviation for the proposed Mission Avenue section, or at
least a request to extend approval of the Design Deviation for the Mission Avenue section submitted
for phase 1, is needed.
9. Delete "Not Approved for Construction", as the certification statement explicitly approves the plans
for construction. The purpose of the entire process is to ensure that a"ready-taaccept" set of plans is
submitted, in order to minimize the number of resubmittals

10. Curbs less than 0. 8% need to have the grades and elevations verified by a P. L. S., per the Standard
Notes provided at the pre-design meeting. Soil in swale floors needs to meet percolation requirements
per Standard Notes provided at the pre-design meeting. Copy of Standard Notes is attached for your
reference
Other:
a. The Statement of Agreement for Construction Services needs to be notarized, per the format provided
at the pre-design conference (copy attached)
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
}ob site whenever construction is in progress.
4) If the Contractor discovers any discrepancies between the plans and existing conditions encountered,
the Contractor shall inunediately 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 utility location service at 456-8000 before you dig.
Optional Notes (when aolicable to projectl
7) For any curb grades less than 0.8% (0.008 ftlft), a Washington State-licensed Professional 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
conect plan grade and elevation prior to concrete placement. The cross-gutters shall be constructed
prior to paving, and the pavement shall then match the edge of the concrete cross-gutter
Use note #9 whenever '208' swales are used:
9) The floor of a 208 swale includes the level portion of tbe floor of the swale, and the sideslopes of
the swale up to the 208 overflow elevarion or top of drywell. The soil located in the floor of a ZOS
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
percolation rate of 0.5 inches per hour
Standard Erosion Control Notes
These notes are to be included in the plan set when erosion control facilities are required and incorporated
into the plans.
ER1) An Erosion/Sedimentation Control (ESC) plan is required for this project. Implementation of tbe
ESC plan, and construction, maintenance, and upgrading of the ESC facilities are the responsibility
of the Developer until all construction is completed and accepted by Spokane County, or until
vegetatioa is established throughout the site, and accepted by Spokane County, whichever is later.
ER2) Approval of the ESC plan does not constitute approval of any of the proposed road, storm drainage,
grading or utility design elements shown on the ESC plan.
ER3) The erosion/sedimentation control measures shown are the minimum requirements for the anticipated
site conditions. The Contractor shall inspect and maintain these ESC measures daily, and shall
maintain and upgrade these measures as necessary to prevent sediment-laden water from either
flowing off the site, or into new/existing storm drainage facilities, such as drywells, culverts, or
gravel galleries.
ER4) The Contractor/Developer is responsible for installing Rock Construction Entries at any and all
locations used to enter or exit the project site.
