AGREEMENT
NOW,THEREFORE, in consideration of the terms,conditions,and covenants set forth below,and the
Recitals which are incorporated into this Restated Agreement as if fully set forth herein,the Parties
agree as follows:
ARTICLE 1 - Description of Water Connections
1.1. Friendly Lane Connection ("Friendly Lane Connection"):a temporary six-inch connection
and a potential future emergency connection at the PLM_5.1 portion of the Project
which will connect to Tigard's 18-inch transmission line at a mutually agreeable location
near SW Friendly Lane.
1.1.1. The Parties agree that the WWSS Commission may design and construct a six-
inch connection between the Tigard water distribution system and the Project
within the City of Tigard at SW Friendly Lane,shown on Exhibit A.The point of
connection shall be in a public right of way, and the Parties agree that Tigard
and the WWSS Commission shall have full and complete access at all times to
operate and maintain the valves,vaults,and appurtenances.
1.1.2. The WWSS design will provide for a future permanent emergency connection
with a capacity of five (5) million gallons per day(MGD) near Friendly Lane so
that Tigard can obtain future emergency water supply for its water system from
the Project.The size of the Friendly Lane Connection for this purpose is
anticipated to be 18-inch diameter capable of providing the desired 5 MGD flow
capacity.
1.2. Satsuma Connection ("Satsuma Connection"): one temporary connection will be made
between the Project and Tigard's system using maximum flow requirements as set by
Tigard near SW Satsuma Avenue.
Page 2 of 11
1.3. Additional connection points may be considered in the future under separately
negotiated and executed intergovernmental agreements or by amendment to this
Restated Agreement.
ARTICLE 2 - Cost
2.1. The cost allocation of the Friendly Lane Connection will be determined according to the
percentage split as shown in Exhibit B and as described below. Generally,the cost of this
portion of the Project will be determined as follows:
2.1.1. The WWSS Commission will be solely responsible for all costs to design,
construct,operate, maintain, repair, and replace one six-inch connection for
testing and maintenance of the Project until the entire WWSS is completed and
water is produced and delivered from the WWSS.The size of piping needed for
this purpose is six(6) inches in diameter, including the backflow device and
meter.
2.1.2. Tigard will be solely responsible for all costs to upsize the six-inch temporary
Friendly Lane Connection piping from six(6) inches in diameter to eighteen (18)
inches in diameter for the future permanent emergency connection.
2.1.3. The design of the Friendly Lane Connection shall be compatible with and
provide for interoperability so that the WWSS Commission may use the
connection as described in this Restated Agreement, including filling,testing,
and maintaining the Project and other connecting WWSS transmission projects.
The Agreement cost-split was based on the WWSS Commission design
consultant's engineer's estimate to construct the six-inch connection to
periodically draw testing and maintenance water from Tigard for use in sections
of the WWSS,which will be "Cost A."The design consultant also provided an
engineer's estimate for the additional cost of upsizing the six-inch connection to
a 12-inch connection for the Friendly Lane Connection,the cost of which
includes the cost of the meter and control vaults,which will be"Cost B."
Per the cost-split set forth in the Agreement,the proportion of Cost A
attributable to the six-inch connection to Cost B (i.e., Cost A divided by[Cost A+
Cost B] x 100=Cost A percentage) results in 68%of the cost of the connection
to be covered by the WWSS Commission.The remaining proportion (32%)will
be covered by Tigard,as identified in the "Cost of Work" and "True-up to Bid
Costs"sections of Exhibit B.
The construction contractor's bid for the 12-inch connection for the Friendly
Lane Connection is reflected in the"True-up to Bid Costs" on Exhibit B. Per
Tigard's request to construct an 18-inch connection at the Friendly Lane
Connection,the WWSS Commission requested a change order from the
construction contractor.The construction contractor's bid for the 18-inch
connection for the Friendly Lane Connection is reflected in the"Change Order
Costs"on Exhibit B.The "Total Actual Costs" on Exhibit B reflect the costs for
each Party.
2.1.4. The WWSS Commission has bid the work as described in Article 1 to establish
the construction cost for that work.
Page 3 of 11
2.1.5. Tigard will be billed its "Total Actual Costs,"as identified in Exhibit B. Half of the
payment will be invoiced upon signature;the other half will be invoiced in July
2020. Payment will be due and payable to TVWD within thirty(30) days of the
invoice.
2.1.6. Tigard acknowledges Washington County will manage the contract for the
actual construction of the connections to the Tigard system.The WWSS
Commission will notify Tigard of any potential construction contract change
orders that may affect Tigard's cost for the connection construction at the
earliest possible time after the WWSS Commission receives notice from
Washington County.The WWSS Commission will endeavor to avoid or minimize
change order requests from Washington County that affect Tigard. If Tigard
does not approve the change order that increases Tigard's cost,the Parties
recognize that Washington County, in its sole discretion or with approval by the
WWSS Commission, may still approve the change order. In such case,the WWSS
Commission will be responsible to pay the change order amount, provided,
however,that the WWSS Commission may seek contribution from Tigard for
Tigard's proportional share, as defined in Article 2.1.3.The Parties reserve all
rights as to responsibility for payment and agree to resolve the matter through
dispute resolution.
2.1.7. If Tigard successfully negotiates an agreement for a future permanent
emergency connection at the Friendly Lane Connection,Tigard will be
responsible for the full cost of additional design, management, and construction
of the full build-out of the emergency connection. Costs for designing and
constructing the Friendly Lane Connection as a permanent emergency
connection will be the sole responsibility of Tigard and shall be included as part
of a future emergency water supply intergovernmental agreement.
2.2. All costs associated with the temporary connection of the Project at Satsuma Avenue will
be paid in its entirety by the WWSS Commission.
ARTICLE 3 - System Connections and Operation Protocols
3.1. For both the emergency and temporary connections:
3.1.1. During and following construction, each Party shall appoint a representative to
coordinate the use, operation, maintenance, repair,and replacement of the
connection and valves according to prudent utility practices.
3.1.2. The Parties agree to maintain their portion of the connection in good working
order so that they are available to be put in service when a water draw is
needed.
3.1.3. The WWSS Commission representative will develop a schedule for Project water
requirements and provide it to the Tigard representative for review and
approval so Tigard will have sufficient notice(minimum 48 hours) of when the
WWSS Commission will need to draw water from the Tigard system.The project
schedule should be updated and provided to Tigard on a weekly basis during the
Project construction period.
Page 4 of 11
3.1.4. The flow from the Tigard system shall be limited to no more than 700 gallons
per minute without prior authorization from Tigard, and Tigard will maintain
control and operate all valves which are part of the Tigard system.Tigard
requires 48-hours notification for the operation of valves.
3.2. Additional conditions to accommodate the permanent emergency connection for the
Friendly Lane Connection include the following:
3.2.1. WWSS Commission will install two 18-inch isolation valves,a six-inch flow
meter, and a six-inch approved backflow prevention device that will connect to
the Tigard system. Both isolation valves will remain closed to the Tigard system
except for those periods when water from Tigard will be used to test the
Project.
3.2.2. The Parties will be responsible for and maintain control of separate valves,
vaults,and appurtenances, including all costs associated therewith as defined
here. Responsibility will be as shown in Exhibit A with the piping from the WWSS
main pipeline to the meter vault and the valve separating the two vaults being
the responsibility of the WWSS Commission.The remaining portion from that
valve,through and including the pressure regulating/control valve and vault to
the point of connection with Tigard's system,will be the responsibility of Tigard.
ARTICLE 4 - Term
4.1. The term of this Restated Agreement and use of water by the WWSS Commission shall
continue until construction of the WWSS is complete and potable water delivery service
begins,which is anticipated to occur in 2026.This Restated Agreement shall
automatically terminate when both: (a)the WWSS is complete;and (b)the WWSS
begins potable water delivery service to TVWD, Hillsboro,and Beaverton. Upon
termination under this section, and if Tigard does not wish to have the permanent
emergency Friendly Lane Connection as described in this Restated Agreement,the
WWSS Commission will remove the six-inch connection,and cost splits for the removal
of the connection will be as defined in Article 2.1.3.
ARTICLE 5 - Future Tigard Agreement
5.1. This Restated Agreement confers no rights or privileges upon Tigard to the WWSS,to
the Project,or to any water through or from the WWSS. If Tigard desires a permanent 5
MGD permanent emergency connection at the Friendly Lane Connection or other
connections to the WWSS,then Tigard must negotiate and seek approval for a separate
agreement regarding construction,connection, metering,and use of WWSS water for
the permanent emergency connection at the Friendly Lane Connection or other
connections.The WWSS Commission will not provide WWSS water to Tigard in the
absence of such an agreement.The permanent emergency Friendly Lane Connection
shall be the sole cost responsibility of Tigard, including any and all costs of making the
conversion to a permanent connection, including, but not limited to, a seismic valve,
electrical, SCADA,flow control devices, and a meter to measure usage.
ARTICLE 6 - Construction Coordination
6.1. The design and construction of the Friendly Lane Connection, including any permanent
emergency connection, in this Restated Agreement will be conducted as part of the
Page 5 of 11
Project and the Road Project.The Parties will coordinate with each other during the
design and construction to provide for minimal inconvenience to each other.The Parties
will each conduct review and approval of construction submittals, other than permit
applications, at no charge to the other Party.The WWSS Commission will coordinate
with Tigard on the inspection of the facilities associated with the connection.
6.2. The design and construction of the temporary connection in this Restated Agreement
will be conducted by WWSS Commission and its contractor with coordination per
Article 3.1.
ARTICLE 7 - Fiscal and Operational Impacts and Use of Water
7.1. The Parties agree to work together to determine how best to provide the water to fulfill
the need to test the sections of the Project. When temporary water is required ("water
draw"),the WWSS Commission will notify Tigard (48-hour notification)to coordinate the
timing, method,and conditions for drawing water into the WWSS from Tigard.The
water will be sold by Tigard to the WWSS Commission as outlined in Article 8.
ARTICLE 8 - Cost of Water and Payment
8.1. Following the sale by Tigard after a water draw under this Restated Agreement,Tigard
will read the meter and determine the quantity supplied.
8.1.1. Tigard will sell water to the WWSS Commission,and the cost of the water shall
be charged for the actual water used at the Tier One residential rate or a rate
that is at or below the approved residential customer class rate adopted by
Tigard. Recognizing the short-term and sporadic nature of the need,there will
be no system delivery charge,system development charge, connection fee, or
other fixed charge associated with this use.
8.1.2. The cost of water, as determined under Article 8.1.1,will be billed by Tigard to
the WWSS Commission and payable within thirty(30)days of invoice.
ARTICLE 9 - Indemnity
9.1. Each Party agrees to indemnify and hold harmless the other Party, its officers,
employees, and agents from and against all claims,demands, and causes of actions and
suits of any kind or nature for personal injury, death, or damage to property on account
of or arising out of services performed or the omissions of services or in any way
resulting from the negligent or wrongful acts or omissions of the indemnifying Party and
