Jefferson County Pl!blic Utility District No. 1 JffffRSON COUNTY DeD
Scope of Work
Marrowstone Island Water System, Phase 2 Wetland
Delineation for Local Utility District No. 14
I -
The following scope of work has been developed at the request of the Jefferson County Public Utility
District No.1 (pUD No.1). The utility district is proposing to install a new water supply system on
Marrowstone Island. The water system will be constructed in phases and Phase 2 includes the installation
of water service tying into the Phase 2 water service on public and private roads to the south of Fort
Flagler State Park. At this time, the proposal is to install the water service within the shoulders of paved
roads and within the roadbed of gravel roads. A wetlands reconnaissance by Parametrix in July 2005
identified approximately 36 wetlands within the proposed Phase 2 project area (see attached figures for
general wetland locations). The purpose of this scope of work (SOW) is to describe the approach, tasks,
and costs associated with a delineation of wetlands in the Phase 2 project area and to address preparation
of a biological evaluation for compliance with the Endangered Species Act.
Objective:

Site visits to meet with PUD NO.1 or regulatory agency staff are not included in this
task.
>-- The route for the Phase 2 water service (project area) will be confirmed by the
PUD staff prior to the delineation. Changes in the confirmed Phase 2 route may
involve additional site visits that are not covered in this SOW or budget.

Task 03 - Wetland Delineation, Phase 2 of proposed Marrowstone Island Water System
Objective:
Approach:
Assumptions:
Determine the area of wetlands and wetland buffers, as well as potential
wetland/buffer impacts from the Phase 2 water service route within the project area.
Prepare critical areas documentation as required by Jefferson County Unified
Development Code (ODC) Chapters 3.6.9 and 3.6.10G).
'....
Parametrix shall identify and flag the boundaries of wetlands within approximately
20 feet of the paved road edge for the proposed Phase 2 water service. The current
project area includes approximately 6,500 feet of wetland edge at 36 wetlands (see
attached figures for general wetland locations) identified during the July 2005
wetland reconnaissance survey and not yet delineated. Ten wetlands were delineated
for Phase I in August 2005.
Wetlands will be identified based on the methods defined in the Corps of Engineers
Wetland Delineation Manual (Environmental Laboratory 1987) and the Washington
State Wetlands Identification and Delineation Manual (Washington State Department
of Ecology 1997). Wetlands will be classified following the U.S. Fish and Wildlife
Service's wetland classification system (Cowardin et al. 1979) and rated using the
Washington State Wetland Rating System for Western Washington, 2nd Edition
(Ecology 1993), as specified in UDC S3.6.9(a)(1). Field data supplemented with
background materials, including NW1 maps, Jefferson County critical areas maps,
and orthophotographs will be used to rate delineated wetlands. Parametrix will meet
on-site with PUD No. 1 staff following the delineation to discuss the survey results.
This task also includes the following:
~ Establishing upland and wetland sample plots, and collecting soils, hydrology,
and vegetation data as needed to identify wetlands.
~ Marking wetland boundaries and sample plot locations with flagging.
~ This task includes 8 hours for coordinating with the survey crew to ensure that
the wetlands and buffers are accurately mapped.
~ The delineation area includes wetlands identified during the July 2005
reconnaissance survey along the proposed Phase 2 roads. These wetland areas
are located within or adjacent to the proposed water service alignment and may
be impacted by Phase 2 construction activities.
.~ Wetlands will be delineated parallel to the road and within approximately 20 feet
perpendicular to the edge of pavement. Where a roadside ditch is present,
wetlands will be delineated to approximately 5 feet beyond the top of the ditch
bank opposite the 'road. Where there are no ditches, wetlands will be delineated
to approximately 20 feet perpendicular to the edge of pavement or to a fence line,
ifthe fence is within 20 feet of the road edge.
~ Wetland delineation will be completed within three weeks of receiving written
notice to proceed.
~ Wetlands will be sketch mapped in the field and sketch maps will be provided to
surveyors to assist in accurately surveying delineated wetland boundary and data
plots.

>- Parametrix will add surveyed wetland boundaries (provided by the POD) for the
10 delineation sites to the base map.
>- Parametrix will also map the OHWM, 200-foot shoreline jurisdictional zone, and
wetland buffers on the base map.
>- Wetland and buffer impact analysis will be based on the surveyed drawings of
delineated wetland boundaries provided by PUD NO.1.
>- The draft base map will be completed within 2 weeks of receiving the mapped
delineation boundaries and topographic features.
>- POD No.1 will have one review opportunity to comment on the draft base map.

the purposes of the BE, the proposed action will include the full extent of the Phase 1
and Phase 2 water system installation (Fort Flagler to Indian Island).
Review documented records in the project area of species federally listed as
threatened or endangered under ESA, assess potential project related impacts to
listed species, and recommend conservation and mitigation measures to avoid or
minimize those impacts.
~ Proj ect will not result in take of listed species or adverse impact to designated
critical habitat or important habitat features for listed species (i.e., bald eagle nest or
perch trees).
~ Formal consultation with U.S. Fish and Wildlife Service (USFWS) and NOAA
Fisheries (the Services) will not be required and is not included in this SOW

Task 08 - Prepare Joint Aquatic Resources Permit Application (JARPA) Form
Objective:
Approach:
Assumptions:
Obtain necessary state and federal permits for work near waters of the U.S. and
waters ofthe state, particularly work in the vicinity of the Schwartz Road wetlands,
delineated wetlands and shorelines of Mystery Bay and Scow Bay.
Parametrix will prepare the JARP A form after reviewing previously collected
information concerning wetlands and waters of the state and CAD files and other
available design drawings for the proposed project to ensure that impacts subject to
state and federal permitting requirements have been identified and documented.
~ Horizontal directional drilling has been identified as the construction
method for water line installation beneath delineated wetlands and shorelines
at Schwartz Road, Mystery Bay, and Scow Bay. Changes in construction
methods (i.e., open trenching) will require additional impact analysis,
resubmittal of a revised JARP A form, and will likely require mitigation.
~ The Washington Department ofFish and Wildlife (WDFW) will make the
final determination on the requirements for a Hydraulic Project Approval
for work in the Scow Bay area.
~ The U.S. Army Corps of Engineers (Corps) will make the final
determination on the requirements for Section 404 permits.
~ Preparation of additional permitting materials (mitigation plans) and
agency negotiations, if required, is not included in this proposal.
~ Parametrix will provide hard copies and a draft JARP A package to PUD No. 1
for review and comment.
~ Following receipt of comments from PUD No. 1 staff, the final JARP A
packet will be prepared. The JARP A will reference the pertinent
supporting documents including the BE and wetland report as appropriate.
