23-211.00CentennialPropertiesLLCCountryVistaMitigationAgreement VOLUNTARY MITIGATION AGREEMENT FOR COUNTRY VISTA
TRAFFIC MITIGATION
Centennial Properties, Inc.
This Voluntary Mitigation Agreement ("Agreement") is entered into between Centennial
Properties, Inc, its successors and assigns ("Developer"), a Washington corporation, having offices at 999
W Riverside Avenue, Spokane WA 99201, and the City of Spokane Valley ("City"), a municipal
corporation of the State of Washington, hereinafter jointly referred to as "Parties":
RECITALS
WHEREAS, this Agreement is entered into by the Parties pursuant to RCW 82.02.020,to provide
a voluntary financial contribution toward the Barker Rd. Improvements — Appleway to I-90 project to
mitigate increased traffic volumes expected to be generated by a portion of the overall development as
proposed in the Developer's permit application LUA-2022-0028 ("Application") in the City of Liberty
Lake and preliminary binding site plan for Centennial Country Vista Drive(the"BSP").
WHEREAS, Developer is the owner and/or developer of certain real property generally located
within an area north and south of Country Vista Drive and west of Henry Lane,identified as parcel numbers
55163.9189,55175.9050,55162.9146,and 55174.9192 in the City of Liberty Lake,and otherwise identified
as Lots 1 through 10 in the BSP consisting of approximately 41.79 acres of land (the "Developer's
Portion").
WHEREAS, Liberty Lake LLC ("Liberty LLC")is the owner and/or developer of all real property
contemplated in the Application other than the Developer's Portion ("Liberty LLC's Portion"), such that
the Developer's Portion and Liberty LLC's Portion together comprise the "Development".
WHEREAS,the Developer has requested final approval of the BSP,which the City anticipates will
increase traffic congestion and directly impact existing transportation infrastructure at the intersection of
Appleway Ave. and Barker Rd. located within the City.
WHEREAS, the City of Liberty Lake issues a Mitigated Determination of Non-Significance
("MDNS") as part of the approval process pursuant to the Development's State Environmental Policy Act
("SEPA")review,which MDNS requires the Developer to enter into a traffic impact mitigation agreement
as a condition to granting final approval of the BSP.
WHEREAS, the Trip Generation and Distribution Letter for the Development, dated September
23, 2022, states the Development is expected to generate 1,665 new trips during the AM peak hour and
1,647 new trips during the PM peak hour for the roadway network upon full build out. Of the 1,647 new
PM peak hour trips, 957 are expected be introduced into the City's traffic system, causing a need for
additional improvements at the intersection of Appleway Avenue and Barker Road,the Barker Road and I-
90 interchange, and intersections along the South Barker Road Corridor(the"Improvements").
WHEREAS, through further analysis, dated June 28, 2023, the City determined that the planned
improvements to the South Barker Corridor from the Eastbound I-90 on-ramp to Appleway Avenue will
only accommodate 1,400 of the expected 1,647 (approximately 85%)new PM peak hour trips entering the
South Barker Corridor due to the Development.
WHEREAS, of the 1,400 new trips accommodated by the Improvements, 893 have been allocated
to the Developer's Portion,with 507 allocated Liberty LLC's Portion.

WHEREAS, the City and Developer have agreed to a voluntary mitigation per trip fee to be paid
in connection with Developer's share of the new PM peak hour trips.
WHEREAS, a full traffic impact analysis will need to be performed prior to approval of the 894th
trip resulting from development of the Developer's Portion as a means to identify an appropriate per trip
mitigation fee for any trips over 893.
WHEREAS,pursuant to RCW 82.02.020,the City has the authority to allow a payment to mitigate
a direct impact that has been identified as a consequence of a proposed development. The Parties have
identified (1) transportation impacts that will be caused by the development of Developer's Portion; and
(2)a reasonable relationship between said impacts to the City's transportation system and the Developer's
financial contribution toward those impacts.
WHEREAS,the City and City of Liberty Lake are parties to an interlocal agreement wherein each
agree to give full faith and credit to the traffic mitigation measures imposed by the other city on
development that has a demonstrable impact on the traffic facilities of the city imposing the mitigation
measures.
WHEREAS, to mitigate the direct impacts of the Development upon transportation facilities, the
Parties are voluntarily entering into this Agreement pursuant to RCW 82.02.020.
AGREMENT
NOW, THEREFORE, in consideration of the mutual covenants and conditions contained herein,
the Developer and the City agree as follows:
1. Voluntary Agreement. This is a voluntary agreement pursuant to RCW 82.02.020. The
Parties agree and acknowledge that the(a)mitigation payment identified in paragraph 3 of this Agreement,
and (b) procedures identified herein to determine further mitigation measures are freely and voluntarily
agreed to as a contribution proportional to and reasonably necessary to mitigate the direct traffic impacts
created by the Development. The Parties further stipulate and agree that all Washington state law
requirements for creation of a valid development impact mitigation agreement have been met, including
but not limited to RCW 82.02.020 and case law interpreting the same, and that neither the Developer nor
the City will claim otherwise.The Parties agree that the calculations of the mitigation fees identified herein
are unique to this Agreement and may not be used as a basis for the negotiation with Developer of any
future traffic mitigation agreements.
2. Projects. The Parties agree that the mitigation payment shall be expended by the City on
design, right-of-way acquisition, and/or construction of the Improvements. The City may allocate all or
any part of the mitigation payment to any component of Improvements as determined appropriate by the
City in its reasonable discretion.
3. Primary Mitigation Fee. The Primary Mitigation Fee ("PMF") only mitigates the first
893 new peak hour trips resulting from the development of Developer's Portion. Said fee is based on
calculations provided by the City in the technical memorandum dated June 28, 2023, entitled
Barker/Appleway Traffic Assessment of the Country Vista Binding Site Plan(attached hereto as Exhibit A).
The Developer agrees to pay a PMF of Nine Hundred Twenty Two Dollars and Forty-Seven Cent($922.47)
per trip for each of the first 893 new PM peak hour trips, to mitigate the traffic impacts resulting directly
from the development of Developer's Portion.
Page 2 of 7
61285.0001.159773 23.1
4. Payment of the Primary Mitigation Fee. The total PMF shall be distributed based on the
building permits issued for construction within Developer's Portion. When the Developer(which includes
its successors in interest, assigns, and grantees) applies for a building permit within Developer's Portion,
they shall pay $922.47 per new PM peak hour trip that will be generated from the use for which a building
permit is sought. The Developer(which includes Developer's successors in interest, assigns, and grantees
per Section 9 of this Agreement)shall pay the PMF for each new trip before the building permit is issued.
No building permit will be issued unless and until the associated PMF is paid in accordance with this
Agreement. At any time, the Developer may pre-pay as many new PMF trips as it may deem appropriate,
provided the Developer identifies in writing the specific lot(s)to which the pre-payment(s)apply.
5. Supplemental Mitigation Fee. The Supplemental Mitigation Fee("SMF")mitigates the
traffic impacts resulting from any new trips in excess of 893 that are generated from the development of
Developer's Portion. The SMF, on a per trip basis, must be determined and paid prior to any building
permit being issued for a parcel within Developer's Portion if approval of the application would result in
more than 893 total trips generated by the development of Developer's Portion.
To determine the appropriate per trip SMF for the Development, the Developer and Liberty LLC
shall each pay a pro-rata portion (based on total costs and contributions from other parties responsible for
mitigation costs resulting from the Development) and arrange for a full traffic impact analysis ("TIA").
Upon receipt of the TIA, the City, Developer, and Liberty LLC will agree, in good faith, on: (1) the cost
to acquire additional right-of-way and design and construct the right-of-way improvements necessitated by
the Development's traffic impact remaining unmitigated under this Agreement and the corresponding
agreement between the City and Liberty LLC to mitigate impacts from Liberty LLC's Portion; and(2)the
corresponding per trip SMF. If the City, Developer, and Liberty LLC cannot agree on the cost of such
required mitigation and improvement costs after mediation, then the matter shall be submitted to binding
arbitration under the Washington Arbitration Act.
6. Payment of Supplemental Mitigation Fee. The SMF shall be distributed based on the
Qualifying Building Permits applied for and/or issued for parcels within the Developer's Portion of the
Development. "Qualifying Building Permits" are those building permits sought for construction within
Developer's Portion when, at the time of application, the total building permits that have already been
issued or applied for within Developer's Portion are expected to generate at least 893 PM peak trips total.
The applicant for each Qualifying Building Permit shall pay a per trip SMF based on the number
of trips that will be generated from the use for which a building permit is sought. The developer shall pay
the SMF before the Qualifying Building Permit is issued. The Developer may at any time pre-pay as many
new SMF trips as it may deem appropriate, provided (1) the SMF has been determined by agreement or
arbitration; and(2)Developer identifies in writing the specific lot(s)to which the pre-payment(s) apply.
When the issuance of a building permit will create trips both within and above the 893 trips covered
by the total PMF, taking into consideration the cumulative trips that will be generated by uses for which
building permits have already been issued and/or applied for, then the Developer must pay(a)the per-trip
PMF for those trips causing the total Developer's Portion generated trips to equal 893; and(b)the per-trip
SMF for the balance of trips expected to be generated by the use for which the building permit is sought.
7. Compliance with RCW 82.02.020. Payments collected by the City shall be held in a
mitigation fee reserve account and may only be expended towards the design, right-of-way acquisition,
construction, and other related components of the projects identified in section 2 of this Agreement. The
City shall be entitled to reimbursement from the mitigation fee reserve account for any funds it may expend
for the design,right-of-way and construction prior to the collection of the fees. The mitigation fee payment
shall be expended by the City within five years from the date of payment by the Developer. Pursuant to
Page 3 of 7
61285.0001.159773 23.1
RCW 82.02.020, any funds in the mitigation fee reserve account not expended within the five-year period
identified above shall be refunded by the City to the Developer with interest; however, if the payment is
not expended within five years due to delay attributable to the Developer, the payment shall be refunded
without interest.
8. Notice. All communications, notices or demands of any kind which a party under this
Agreement is required or desires to give to any other party shall be in writing and be either:

Memorandum
Date: June 28, 2023
To: File
From: Jerremy Clark, PE, PTOE—Traffic Engineering Manager
Re: Barker/Appleway Traffic Assessment of the Country Vista Binding Site Plan
Introduction
This memorandum summarizes an evaluation completed to assess the impact of traffic related
to the Country Vista Binding Site Plan (BSP)to the intersection of Barker Road and Appleway
Avenue. The proposed development project is located east of Henry Lane, north and south of
East Country Vista Drive, in the City of Liberty Lake. The BSP assumes 1,176 apartment units,
1,092,485 square feet of commercial use, and one convenience store/gas station according to
the trip distribution and generation letter(TGDL) included with the SEPA notice of application
(NOA) circulated on September 27, 2022. As noted in the TGDL, the development is expected
to generate 1,665 trips during the AM peak hour and 1,647 trips during the PM peak hour. Of
these trips, 957 trips are estimated to go into the City of Spokane Valley and through the
intersection of Appleway Avenue and Barker Road during the PM peak hour. Likewise, 1,011
trips are expected to go through that same intersection during the AM peak hour (see Figure 5
of the TGDL).
A previous analysis was completed to identify the need for mitigation at the Appleway/Barker
intersection. This evaluation was completed to quantify the proportionate-share contribution
toward the mitigation identified in the City's 6-year Transportation Improvement Program (TIP).
This memo includes the following sections:
• Mitigated Capacity
• Proportionate-Share Calculation
• Summary
Mitigated Capacity
The Appleway/Barker intersection has been shown to deteriorate below acceptable levels of
service prior to the inclusion of the Country Vista BSP trips. There is a planned improvement
along the Barker Corridor that improves the operations at this intersection. Channelization and
signalization improvements at the Barker/Appleway intersection are included in the City's
Transportation Improvement Program (TIP) Project#41, which includes a widening of the 0.29-
mile section of Barker Rd from Appleway Ave to the 1-90 interchange. The southern portion of
this improvement was evaluated with the additional volumes from vested trips and the Country
Vista BSP. Traffic from the Country Vista BSP causes the Appleway Avenue and Barker Road
Intersection to fail, even after accounting for improvements. As a result, an analysis was
completed to determine how much of the BSP trip generation could be accommodated by the
City's TIP project. This was completed through an iterative series of evaluations at various
Exhibit A
Barker/Appleway Traffic Assessment of the Country Vista BSP June 27, 2023
Page 2 of 3
levels of completion. As summarized in Table 1, below, the proposed TIP project at
Appleway/Barker can accommodate approximately 85% of the Country Vista BSP trips that are
distributed through the intersection. This equates to 814 out of 957 trips expected to travel
through the intersection.
The analysis was based on a 120 second cycle length for the traffic signal to maintain
consistency. The signal timing for the 85% volume scenario was adjusted to 110s to
accommodate all phases with an acceptable level of service. As shown in the last row of the
table, the expected delay with 85% of development is 54.4 seconds per vehicle during the PM
peak hour. The threshold for the maximum delay for an acceptable level of service is 55
seconds.

Proportionate Share Calculation
Given the established requirement for mitigation, the proportionate share of the mitigation cost
was determined for the proposed BSP. In addition to the deficiencies at Appleway and Barker,
a separate analysis completed by the developer's consultant identified deficiencies at the 1-90
EB Ramp and Barker. The improvements at the 1-90 ramp were shown to be mitigated by the
addition of a northbound right turn lane onto the eastbound entrance ramp. This improvement
would tie in to the City's TIP project for a 5-lane Barker between 1-90 and Appleway, but was not
included in the original project scope. As a result, the project cost estimate was updated to
include the ramp intersection improvements and reflect current construction and right-of-way
pricing. In project cost estimate was further refined to only include those components necessary
for mitigation of the BSP, as described below.
Exhibit A
Barker/Appleway Traffic Assessment of the Country Vista BSP June 27, 2023
Page 3 of 3
Project Cost
The total cost of the City's TIP project was revised to account for current construction and right-
of-way pricing and to incorporate refinements into the planning-level design. Excluding the
proposed roundabout to be built at the Broadway/Barker intersection, the updated cost of the
Barker: Appleway to 1-90 project is expected to exceed $11.5M.
As analyzed, the Country Vista BSP will contribute to deficiencies at the 1-90 EB ramp and the
Appleway intersection. In order to provide mitigation specific to the development, the project
was broken down into two components:
• Improvements at the 1-90 EB ramp intersection with Barker,to include improvements 320' south
on Barker. This is approximately the area between the west leg of Broadway Avenue and the I-
90 EB ramp. Based on analyses completed by the developer's consultant,the queues on the
northbound approach with the proposed northbound right turn lane are expected to reach 319'.
By extending the capacity for the right turn lane at the ramp intersection,this should maintain
access to the right turn lane.
• Improvements at the Appleway intersection with Barker,to include improvements 500' north of
Appleway. At 85%buildout of the Country Vista BSP,the average queues for the southbound
left turn lane during the PM peak hour are estimated at 488'. As a result, a length of 500'for
improvements is required to accommodate the required storage and minimize spillback.
Given these two elements of the overall project, the cost estimate was revised to exclude the
"middle" portion of Barker Road. The resultant cost estimate mitigable by the BSP is $9.5
million, which includes a substantial right-of-way component.
Cost Participation
Based on a known volume that can be accommodated by the intersection, a proportionate share
calculation was completed in a similar manner as accepted in the Neighborly Ventures
determination and mitigation. The process is described below:
• The total existing volume of the two intersections, including all vested projects but
excluding the proposed BSP was determined, as listed below:
o 1-90 EB at Barker : 2,151
o Appleway at Barker : 3,220
• The additional volumes contributed by the development were determined for the two
intersections, which vary between 85% build at Appleway/Barker and 100% build at 1-90
EB/Barker.
O 1-90 EB at Barker (100%) : 297
o Appleway at Barker(85%) : 814
• The proportionate share of the BSP project toward the intersection volumes was
calculated for each intersection, as described below:
O 1-90 EB at Barker : (297/2,151) = 13.81%
o Appleway at Barker : (814 /3,220) = 25.28%
• The total volume of the two intersections including the BSP project were determined, as
listed below:
o 1-90 EB at Barker : (2,151+297) = 2,448
o Appleway at Barker : (3,220+814) = 4,034
Exhibit A
Barker/Appleway Traffic Assessment of the Country Vista BSP June 27, 2023
Page 4 of 3
• The weighted average of the two separate proportionate shares were determined to
identify the proportionate share of the overall project cost estimate, as summarized
below. This was determined by multiplying the cost participation of each intersection by
the total volume of each intersection including the project, adding the values together,
and dividing by the total volume of both intersections.
0 (2,448 x 13.81%)+(4,034 x25.28%) = 20.95a
(2,448+4,034)
• The proportionate share of this project toward the reduced portions of the Barker: 1-90 to
Appleway improvements is estimated at$1,989,963.51 (20.95% of$9,500,000)
• The total allowable trips for the development permitted within this mitigation are 1,400
(85% of 1647).
• Given a potential mitigation strategy of delegating costs to each component of the
development, the cost per trip was calculated based on a development total of 1,400
trips, as summarized below:
O $1,989,963.51trips = $1,421.40 per trip
1,400 trips
Summary
This document summarizes an evaluation completed to estimate the impact of trips generated
by the Country Vista BSP in the City of Liberty Lake added to the Spokane Valley intersections
of the 190 EB ramp at Barker Road and Appleway Avenue at Barker Road. As documented by a
prior analysis, the addition of project trips to the Appleway/Barker intersection is expected to
contribute to an already deficient level of service during the PM peak hour. As documented by a
separate analysis by the developer's consultant, the addition of project trips to the 1-90 EB
ramp/Barker intersection is expected to cause a deficient level of service. There is a planned
project along the Barker Corridor between 1-90 and Appleway Avenue that will improve
operations in this area. This project was modified to include a northbound right turn slip lane at
the 1-90 EB ramp intersection. The northern and southern portions of the Barker corridor project
were assessed as mitigation for the deficient levels of service attributed to the project. The
planned project was shown to accommodate up to 85% of the additional trips generated by the
development through the Appleway/Barker intersection and 100% of the additional trips through
the 1-90 EB ramp/Barker intersection. The additional project trips through these intersections
constitute a 20.95% contribution to the mitigable portions of the corridor project. As determined
through a proportionate share calculation and presented herein, the project mitigation of the
Country Vista BSP is estimated at$1,989,963.51, or$1,421.40 per trip.
