1.0 Introduction
The City of Spokane Valley (Spokane Valley) has contracted with Morgen & Oswood
(M&O), for the Barker Road Bridge Replacement Project (replacing the existing 2-lane
bridge structure with a wider 4-lane bridge structure over the Spokane River, and the
project includes sidewalks and bicycle lanes). As pazt of the construction, a Memorandum of
Agreement for Syokane River Aquatic Imynct Mitigntion must be prepared and signed by the
affected parties: Washington State Department of Fish & Wildlife (WSF&S), Spokane
Valley, and the Spokane County Conservation District (Conservation District). It may also
be necessary for a separate memorandum of agreement or construction contract change
order to be enacted between Spokane Valley and M&O.
The purpose of this Mitigation Assessment is to determine the compensatory mitigation for
Spokane Valley as a condition of the hydraulic project approval (HPA) 110492-3, issued on
December 3, 2007. The compensatory mitigation will be determined based on anticipated
impacts associated with construction activities (work).
2.0 Mitigation Impacts
Mitigation impacts are defined as those that will occur in the river water below the ordinary
high water line (OHWL) when proposed work or activity is:
• Outside of the approved wark window as established by the approved HPA, issued
December 3, 2007
• In conflict with any other provision of the approved HPA, issued December 3, 2007
• In conflict with the Mitigation Policies of WSF&W as per technical memorandum dated
January 18,1999 (POL-M5002)

2.1 Working Outside of the Approved Work Window
The approved work window issued under the HPA is from June 15 through August 31 of
2008 and also the same time period for 2009. Table 1 is a summary of work activities that are
_ anticipated.to occur outside of the approved work window with anticipated.durafion of
these activities (based.on proposed construction schedule), and comments related to
mitigation measures that will be unplemented.to avoid or minunize impacts to fish &
aquatic habitat.

Mticipated Work Occurring Outside of the HPA Approved Work Window (June 15- August 31, 2008-2009)
Work Activity Potential Duration Construction Methods '
Remove Exisling Bridge Approx. 3 weeks A debris collection tub, suspended by cranes under the
Superstructure work construction area to caplure all bridge demolilion
and debris, will prevent bridge pieces or debris from
dropping into the river. All bridge parts/pieces and
debris will be captured, dumped into lrucks, and hauled
away to an approved disposal site. Large bridge parts or
pieces will not be dropped into the river and then '
retrieved for disposal as currenlly allowed by the HPA.
, Instead, large bridge parts or pieces will be removed by
crane.
Work will occur outside of approved work window.
. No contact with river water is anticipated
throughout duration of work activity.
Install Work Bridge Approx. 3 weeks Steel pipe support piles will be capped with a conical
(Main Deck) point to prevent sediments from entering the pipe and
later being released into the river when the piles are
_ removed. All piles will be driven and removed only once
(a series of inslalling and pulling pipes is not
necessary).
Creosote treated timber (8"x16"x30') is proposed by lhe
. Contractor for the decking. (This is not currently allowed
in the permit.) The treated timber will be encapsulated
with an impervious wrapping that will be secured in
place and completely covered wilh wood sheeting. This
cover will prolect the limbers from chipping, i.e. if track
, mounted equipment operates on the work bridge,
setting of equipment outriggers, etc. The wrapping and
wood sheeting combined will provide an impervious
surface that will remain strong and secured in place,
preventing any contact of the treated timber with
precipitation and protecting the river water.
, Should any timber be dislodged from lhe work bridge
structure and dropped into lhe nver or any other water
quality problems or fish kill occur, immediate action shall
be made to notify Washington Military Emergency
Management Division at 1-800-258-5990 (see Section
2.2 and Section 3.0 for further discussion).
Work occurs outside of approved work window,
which would happen in the fall of 2008.
Install Laterals on Work Approx. 2 weeks Laterals will be constructed on the work bridge,
exlending from lhe main work bridge deck along each .

2.3 Conflict with the WSF&W Mitigation Policy
The WSF&W has a policy, POL_M5002 Rcquirirtg or Recommending Mitigatiml. No deviations
from this policy have been identified related to the Barker Road Bridge Replacement Project.
Therefore, there are no conflicts with the WSF&W mitigation policy.

3.0 Compensatory Mitigation
3.1 Summary of Impacts:
. The City's Mitigation Plan is based on the following summary regarding potential unpacts to the Spokane River and aquatic wildlife:
1. The most significant work activity ixnpact is caused by working outside of the
approved work window. Most of this work will be done without contacting river
waterbased on debris collection systems and debris management programs working
properly, and based on barrier systems (casings and sheet-pile cofferdams) that will
be constructed to isolate work activities from contact with river water.
Spring spawning will be avoided. All demolition and constnxction work that would
have contact with river water would be completed before the period of tune when
rainbow troutspawn, and eggs incubate and emerge. In other words, in-river work
would not occur between mid-March to mid-June. Therefore, impact to rainbow
trout and other spring spawners should be minunal.
Most wark that would potentially occur in the river that is outside of the approved
work window would happen in the fall and winter. There may be some potential
impacts to fall spawners including brown trout, bull trout, white fish, and other
warm water species.
" 2. Another proposed work activity that has a potential adverse impact is the use of
creosote or pentachlorophenol timbers for the work bridge decking. Controls will be
unplemented (encapsulation of the treated timbers with an unpervious wrapping,
covered and secured in place with wood sheeting, and recovery of all tunbers for
~ reuse) to prevent toxic contamination from entering the river. Therefore, the impact
~ to aquatic species should be minimal. ~
3. The contractor has opted not to use an approved HPA provision, which allowed a
rock dam or dike in the river to be used as a work platform during demolition or
construction. This decision will lessen adverse impacts to aquatic species in the river
` than the approved HPA provision.
4. Should unforeseen circumstances occur that cause adverse impacts (fish are
observed in distress, a fish kill occurs, or water quality problems develop induding
equipment leaks or spills), immediate action shall be made to notify Washington
Military Department Emergency Management Division at 1-300-253-5990 for those
types of circumstances as theV occur. Work will stop immediately, and a meeting
will be held with WSF&W and Washington State Department of Ecology to
determine a course of action.
3.2 Mitigation Calculation Method
There is little guidance on what amount of mitigation is appropriate for potential impacts in
the Spokane River resulting from the Barker Road Bridge Replacement project However, a
precedent agreement with Spokane County for the Argonne Road Bridge mentioned, upon
the recommendation.of the Spokane Cotmty Conservation District (SCCD), that mitigation
TM-MITIGATION ASSESSMENT--094508 FINAL.DOC 7
~ . . ,
BAFKER ROAD BRID MITIGATION ASSESSMEM ,
on the appropriate size of a project could be based on either the length of unpacted shoreline
or square footage of project area. In their case, they deterinined that the length of shoreline
was approxunately 200 feet, but decided to calculate mitigation based on square feet of
riprap. ~
There is no riprap planned or needed for the Barker Road Bridge project and, therefore,
Spokane Valley proposes to use the linear shoreline area.unpacted as the basis for
calculating mitigation. The Area of Potential Effect (APE) for the Barker Road Bridge project
shows that shoreline impacts are approxunately 160 feet (measured parallel to the new
piers). Using the basis of $200/shoreline foot and a shoreline length of 160 feet, the
calculated mitigation fee is $32,000. I
Spokane Valley proposes a lump sum in-lieu fee payment of $32,000 to the SCCD in
accordance with a Mitigation Agreement between the WSF&W, the Conservation District
_ and Spokane Valley. These dollars will be used for off site mitigation performed in the
Spokane River within the Spokane Valley city lunits. If after three years a project within
Spokane Valley has not been identified, the funds may be used on any project the SCCD
deems appropriate.
Any additional mitigation fees or measures that might occur as a result of unforeseen
accidents or events would be the responsibility of the Contractor, Morgen & Oswood, who
will pay far any additional mitigation fees/costs, or unplement additional mitigation
measures as needed in behalf of Spokane Yalley.
Spokane Valley believes that this is a meaningful proposal that will be of benefit to the
Spokane River and will mitigate all of the potenrial impacts.
