SCOPE OF SERVICES

Thunder Hills Sanitary Sewer Interceptor Replacement Project
CAG-16-108 Amendment No. 4
Stantec Consulting Services Inc.
AMENDMENT DESCRIPTION AND PURPOSE
The purpose of this Amendment is to provide for additional design and permitting
services, and to provide for additional effort related to managing the project through
completion of construction, due to the extended schedule.
The budget has also been adjusted to compensate for increases in the billing rates for
Stantec staff members for 2019 services, given the fact the original contract was initiated
in 2016. At that time, the schedule for execution did not foresee the amount of time or
effort that would be involved in completing the environmental documentation and
permitting tasks.
SCOPE OF SERVICES AND TASKS
This scope of services consists of additional work required under the following tasks:
Task 200 Project Management
The project was originally scheduled to be complete (constructed) at the end of 2018.
The project is now scheduled for construction in 2020. Additional project management
services for up to 27 months will be required to meet the current design and
construction schedule, and to account for adjustments in Stantec rates for the
remaining work. In addition, some budget was previously transferred from Task 200 to
keep project activities related to environmental documentation, permitting and
surveying moving, avoiding further project schedule impacts.
Task 201 Surveying
Effort beyond that originally estimated was required to identify the limits of required
easements and complete the associated easement exhibits for the project. This was
significantly influenced by the environmental constraints on the project as well as the
following considerations:
• Additional survey was required to identify location and depth of the 20-inch gas
main described in Task 202.
• Additional right-of way calculations were required to complete the WSDOT
maintenance agreement.

Thunder Hills Sanitary Sewer Interceptor Replacement Exhibit A-2
Amendment 4 Scope of Services Page 2 of 4
Budget was reallocated to this task from the Construction Services budget to complete
the tasks described above to avoid stopping work in order to process a scope
amendment, which would have further delayed the project timeline.
Task 202 Design
The location and depth of the 20-inch gas line needed to be verified to meet the
requirements for the Olympic Pipeline right-of-way use permit and to determine if there
are any proposed conflicts between the proposed sanitary sewer and the 20-inch gas
main. Stantec performed research to identify contractors with the capability to access
the location and pothole to locate the gas main. Stantec identified and coordinated
with Bravo Environmental Services to provide potholing for the gas main. The cost
incurred by Bravo Environmental Services is $10,020.32. Stantec also provided
coordination with Bravo and the City for the potholing effort.This is effort which was not
previously included in Stantec's scope of services. Additional effort was required of the
Stantec engineering team in order to minimize the impact of the proposed facilities and
facilitate both environmental and WSDOT permitting.
Engineering staff have worked closely with and coordinated with the environmental
team to advance the project and ensure it remains technically viable and will meet the
City's goals. We anticipate some additional effort as the WSDOT and WDFW permitting
processes are completed in coming weeks.
The services are also revised to include the additional time and materials for design
revisions implemented during prior 60 and 90 percent design submittals, and to account
for adjustments in Stantec rates for the remaining work.
Task 203 Permitting
The permitting for this project involves entering into a maintenance agreement with
WSDOT for access to the sewer within the WSDOT ROW. Work for this task included
preliminary coordination and negotiation with WSDOT to determine the type of
agreement, and creation of an exhibit for the agreement. During the course of this
aspect of the permitting process, this project's WSDOT component has changed hands
within WSDOT multiple times, leading to inefficiencies in the review process which has
consumed more Stantec time than otherwise anticipated. Additionally, multiple times
WSDOT has been delayed due to understaffing issues, which has lengthened the
processing timeline.The latest and current reviewer, Chad Lee, was assigned in March
2018 and, at that time, he concluded that the utility franchise permit needed to be
updated, and that he would work with the WSDOT regional manager to get a ROW
permit approved for the purpose of this project only. During this time, Stantec provided
several figures, photos, and information (requested by Mr. Lee) to ensure they had the
documentation required to finalize their permitting process. After several follow-up
communications with WSDOT, they responded in June 2018 that an Air Space Lease
would be required for the access road within WSDOT's ROW, The City responded that
they had no Real Estate personnel and would need Stantec to facilitate this
agreement. WSDOT also indicated that a utility franchise would be needed for the
portion of the sewer line rehabilitation within their ROW, and that they would continue
to facilitate that portion on their end. Additional exhibits and information were sent to
WSDOT in August and September 2018, as their real estate contacts needed more

information. In September 2018, Mr. Lee indicated that after his communications with
the WSDOT real estate staff, they felt that a Maintenance Agreement would be the
most appropriate way to handle the City's proposed work on the access road, and
that the utility franchise for the sewer line rehabilitation portion would be issued in
conjunction with that agreement. Stantec proceeded to provide information and
additional figures to WSDOT's Lara Zimmerman and Mr. Lee during the development of
the agreement, approval of which has yet to be forthcoming despite final edits made
in early February 2019.
The following additional items were required in support of the SEPA process during the
Environmental Review Committee (ERC) review:
• Preparation of the Modification Package for the use of retaining walls higher
than the 6 feet allowed by City code
• Communications with the City and subsequent review of plans and calculations
of amount of maintenance access road improvements within protected slope
areas (grades exceeding 40%) to determine that the improvements would not
exceed the 10% exemption allowance and would not trigger a variance.
• Detailed online review of State mapping resources to provide stream
classification clarification and review of the code mitigation requirements were
submitted to the ERC to address Tribal comments submitted during the SEPA
review.
The services are further revised to include the additional time and materials for
preparation of documents and figures related to the Army Corp of Engineers
Nationwide Permit, and to account for adjustments in Stantec rates for the remaining
work.
On February 27, 2019, comments were received from the Washington Department of
Fish and Wildlife (WDFW) regarding the HPA permit application. The comments
originated with the Muckleshoot Tribe (Tribe) "in the interest of protecting and restoring
the Tribe's treaty-protected fisheries resources." The comments include a dispute of the
stream classification, which were determined to need revision based on
communication and clarification with Larry Fisher (WDFW) on February 28, 2019. These
comments from the Tribe include the need for the additional work to clarify various
aspects of project work, request of all trees removed to be placed in the stream, and
revisions to the mitigation plans to address knotweed. In order to perform research,
including a site walk-though to identify areas of concern, perform a site visit with all
stakeholders (City, WDFW, Tribe, and Stantec), as well as properly address recent
comments, an allowance of$10,000 has been added. We do not know the extent of
the total effort required to resolve this issue, so additional budget still may be necessary.
On March 12, 2019, comments were received from the United States Army Corps of
Engineers (USACE) regarding the JARPA permit application.The comments include
requests for additional information, as well as significant revisions to the drawings
submitted for the wetland and stream buffer mitigation to show further information.
In order to perform research, including a site walkthough to identify areas of concern,
perform a site visit with all stakeholders (City, WDFW, Tribe, and Stantec), and to
properly address comments related to both the WDFW and USACE permits, an

Amendment 4 Scope of Services Page 4 of 4
allowance of$1 1,000 has been added. We do not know the extent of the total effort
required to resolve this issue, so additional budget still may be necessary.
Additional scope and budget is also required for the Watershed Company to perform
the required site visits, report revisions, additional technical memorandum, and attend
the required agency meeting to address the WDFW and USACE comments. The total
budget for the additional scope of work is $14,455, or$15,900 with Stantec's markup.
Task 204 Bidding Services
This project was originally scheduled to bid in January 2018. The budget was revised to
address adjustments in rates for Stantec staff effective January 1, 2019.
Task 205 Construction Support Services
This project was originally scheduled to bid in January 2018. The budget was revised to
compensate for original budget reallocated to avoid hampering execution of other
tasks (permitting & design)and to account for Stantec rate adjustments.
