SCOPE OF WORK
(revised January 28,2007)
WETLAND DELINEATION AND ECOLOGICAL ASSESSMENT
KENT EVENTS CENTER
(Commons Playfield, Kent,Washington)
A.0 Kindig & Co. (Dr. Jim Kelley) will review the proposed Kent Events Center site for potential
wetland conditions The work will consist of reviewing background information, completing a field
delineation to identify the locations of wetlands, and preparing technical memorandum that summarizes
our findings Also included in the scope is coordination, as necessary, with the City of Kent and the
project team. Work associated with these tasks is further outlined below.
TASK 1 Preliminary Review of Background Information and Meeting(completed)
Previously completed studies, evaluations, and background information pertinent to the wetland
assessment on or near the project site will be reviewed These documents include-
King County Soil Survey
• King County Wetlands Inventory
• National Wetlands Inventory
• City of Kent Wetlands Inventory
• Kent Critical Areas Regulation
• Preliminary wetland information provided by Adolphson&Associates
• Aerial Photographs available from the City or other sources
• Construction or maintenance records for the park facilities that may indicate drainage problems
The above information will be used to help document and interpret potential wetland conditions on the
project site A preliminary evaluation of the Kent Events Center site will be completed to identify
potential wetlands on or nearby the site
Following the background review, teleconferences and a meeting with the project team will occur to
discuss preliminary findings and further evaluation needs.
[NOTE: Work described in this task was completed as of October 20, 2006 Information obtained in this
Task will be used, as appropriate, in Tasks 2 and 3 J
Scope of Work 1 A C. Kindig 4 Co
Wetland Delineation and Ecological Assessment revised January 28, 2007
Kent Events Center, City of Kent
TASK 2 Field Delineation (Haden and Commons Site)
The Kent Events Center sites(Haden and Kent Commons) will be examined to identify potential wetlands
on or adjacent to the site. The boundaries of any wetlands will be identified on an aerial photograph or
other suitable base map of the project site.
Wetland identifications will be completed according to criteria specified in the Corps of Engineers
Wetland Delineation Manual (Environmental Laboratory 1987), and in Ecology's Washington State
Wetland Identification and Delineation Manual(1997). Wetlands identified on the site will be delineated
according to the three parameter wetland delineation approach specified in these manuals In identifying
wetlands, appropriate consideration will be given to the "normal circumstances"of the site, as clarified in
the Corps of Engineers Regulatory Guidance Letter 86-09
Because of existing land-uses (mowed sports fields), dry weather conditions, and historical hydrologic
alterations, the three required wetland parameters (soil, vegetation, and hydrology) are anticipated to be
absent or unreliable Therefore, historical information (aerial photographs, maps, and other information)
may be used to help support a wetland determination for the site Historical photographs and other
historical information may be used to understand the "normal circumstances"of the site and to determine
what ecological nexus may exist between wetland on the site and other navigable waters
The ecological condition of on-site wetlands will be evaluated determine the appropriate regulatory
rating, potential buffer requirements, and mitigation standards Ecological conditions will also be
evaluated to understand the ecological functions provided by the wetlands and to evaluate whether there
is a "significant nexus"between the wetlands and navigable waters of the U S
TASK 3 Reporting,Meetings, and Coordination
The results of the work described in Task 2 will be summarized in a technical memorandum that
describes current wetland conditions on the Naden and Commons sites. The potential uncertainty in the
wetland determination(due to altered site conditions and completion of the study during early fall)will be
discussed The potential significance of wetlands to project planning and site design will also be
identified As appropriate,the historical alterations to site hydrology and wetlands will be discussed.
The memorandum will discuss wetlands relative to their Clean Water Act jurisdiction This will include
evaluation of whether a wetland is hydrologically isolated from other waters of the U S , adjacent to
navigable waters, or hydrologically connected to other waters. The potential changes in federal wetland
jurisdiction that may result from the recent Rapanos U S Supreme Court decision will also be considered
In this regard, an ecological evaluation of wetlands will be completed and the potential for a"significant
nexus"between any on-site wetlands to other navigable waters or their tributaries will be evaluated
Finally, coordination with City of Kent and the project team are anticipated to occur through
teleconferences and 1 strategy meeting. An additional meeting, on the project site, with the City staff is
planned
TASK 4 Impact Assessment,EIS Assistance, and Buffer Enhancement Plan
A.0 Kindig & Co will evaluate the potential project impacts to wetlands and wetland functions on the
Naden and Commons site Impacts will consider direct impacts (wetland filling) and indirect impact
(impacts to buffers, potential hydrologic modifications, and other disturbances) This analysis will be
included in the wetland delineation report A conceptual mitigation approach will be included in the
report that addresses buffer enhancement and buffer averaging A C Kmdig & Co. will prepare the EIS
section for wetlands,and/or assist Blumen Consulting in the preparation and review of the EIS section
Scope of Work 2 A.C Kindig 6 Co
Wetland Delineahon and Ecological Assessment revised January 28, 2007
Kent Events Center, City of Kent
Following completion of the EIS process, a Buffer Averaging and Enhancement Plan (5 copies) will be
prepared. The plan will consist of a brief technical memorandum (2-5 pages) that specify the general
requirements of the plan.
The Buffer Averaging and Enhancement Plan will also include a full-size plan sheet that shows the design
layout of the proposed project, areas of buffer averaging, buffer enhancement, and wetland enhancement
areas A plant list, specifications, and other landscape details will be included on the plan Tlus plan
sheet will be prepared and printed by the project design engineer/landscape architect A C Kmdtg & Co.
will provide all technical assistance with regard to the wetland and buffer enhancement requirements
Limitations
The following limitations apply to the work described above:
• A.C. Kmdig & Co will not survey or map the wetland boundary. A licensed surveyor will
need to survey and map wetland boundaries for the wetland delineation report.
• Hydrologic observations (occurrence of surface water in adjacent ditches, apparent flow
paths, surface ponding, and soils saturated within the upper 12 inches will be described at the
time of the wetland delineation No other monitoring or analysis is included in this work
• Drainage path and potential hydrologic connections will be evaluated from aerial photographs
and field observations from public right-of-ways These observations will not include any
vegetation clearing or survey that may be required for a complete drainage analysis. Rights-
of-entry and evaluation of private properties is not proposed.
• The city of Kent will provide a topographic survey of the site. The map datum for this survey
and the FEMA Flood Rate Insurance Map will be provided by the City
• Wetland functions relevant to the determination of a "significant nexus" will be evaluated
qualitatively based on standard procedures used by the Seattle Corps District and Washington
Department of Ecology
• The scope does not include effort for permitting any wetland impacts associated with the
project,nor in obtaining regulatory review and approval of any delineated boundaries.
• This wetland buffer averaging pi sheet will be prepared and printed by the project design
engineer/landscape architect A.0 Kindig & Co. will provide all technical assistance with
regard to the wetland and buffer enhancement requirements
