Dear Dave,
Reference: Thunder Hills Sewer Project- Budget Amendment Request
As you are aware, based on our meeting with the Army Corps of Engineers, WDFW, and the
representative from the Muckleshoot Tribe,the City will be required to provide mitigation for this
project in order to secure the permits necessary for construction.Stantec has coordinated with the
Watershed Company (TWC) to provide the attached scope and budget to provide the effort
necessary for obtaining the perrnits.This effort includes mitigation plans required for the JARPA
application, preparing a biological evaluation memorandum, modifying the existing critical areas
report, and a mitigation bank use plan proposal.The cost af these associated tasks by TWC
amounts to$62,720,or$68,992 with Stantec markup,see attached scope from The Watershed
Company for more information.Stantec anticipates that the additional work required to
coordinate the design and specifications required for the mitigation plan will require an additional
$13,500 in budget for Task 202-Design.
Stantec respecttully requests a budget amendment in the amount of:
Mitigation Plans/Biological Evaluation $68,992
Stantec Design Coordination $13,500
TOTAL $82,492
Regards,
ST TEC ONSULTING SERVICES INC.

Sub-consulting Environmental Services
Scope of Work
March 22,2017
The Watershed Company will furnish the following services to Prime Consultant
Stantec:
Project understanding: Impacts to wetlands and streams will be mitigated in two ways:
For Federal permits and in conjunction with comments from WDFW and the
Muckleshoot Tribe,in-stream woody debris habitat will be proposed. For City of
Renton Critical Areas permitting(and possibly Washington Department of Ecology), a
Bank Use Plan will propose credits for withdrawal from the Springbrook Creek Wetland
Mitigation Bank.For buffer impacts,enhancement will be proposed including invasive
weed removal and management and revegetation with native species.
To support the Federal Permit,a Biological Evaluation will be prepared to demonstrate
compliance with the Endangered Species Act. A Critical Areas report will also be
prepared outlining how the project complies with the City of Renton Critical Areas
Ordinance.
Task 1:Proj ect Management(NTE$6,235):
1. Project progress reports and invoice management. Prepare and submit monthly
invoices and update progress to Stantec.
2. Attend up to three in-person project meetings. �
3. Coordinate project tasks and deliverables for the duration of the work.
Task 1 Assum�tions:
1. Project duration will not exceed 3 months.
2. Meeting time plus travel and preparation will not exceed 4 hours each.

c) 60%Specifications/Special Provisions
d) 60%cost estimate
2) One 60°/o revision based on comments from the design team and City of Renton
Public Warks.This revision will become the Permit drawing submittal.
3) Conduct hydrologic analysis to determine design flow(100-year)as well as
intermediate flows, and hydraulic analysis sufficient to determine rough channel
dimensions needed to carry design flows.
4) Participate in coordination with WSDOT for right of way use.
Task 2 Assumptions:
1. The Watershed Company shall be furnished with an AutoCAD survey drawing with
current and sufficient baseline information including contours,parcels, and
delineated critical areas,as well as project design drawings.
2. Log structure placement will be limited to a maximum of 30-logs between Stream D
and the I-405 Culvert. Ultimate project log and size numbers will be based on Fox
and Bolton(2007).
3. Design changes affecting critical areas and buffers will be final prior to completion of
mitigation plans noted above. Subsequent changes to permitting documentation are
not included.
4. Comments on permit submittals from local,state,or federal agencies,including Tribal
comments,related to our plans or documentation may be subjective in nature and are
therefore not predictable.Revisions to permit documents are not included in this
proposal and can be completed on a time and expense basis or under a separate
proposal.
5. Project mileage,reproduction and other expenses are included in the NTE.
6. All deliverables will be furnished electronically.
7. A hydrologic analysis will be conducted to determine the 100-year design flow,

calls and emails. Permit processing and full project coordination is assumed to be
led by others.
