WETLANDS:
Method and Three levels of information were gathered to do the wetland
Approach: determination, delineation and classification. These included:
1. Level I Assessment: Used readily available digital data to develop
background knowledge of ecological site relationships to identify,
delineate and classify potential wetland ecosystems and other water
occurrences on the geomorphic area of land. The available resource
documents used for the Level I preliminary assessment included:
USDA Soil Conservation Service (SCS), "Soil Survey of Jefferson
County Area Washington"2015, 2000, 2005 and 2009 aerial
Ellis 901263023 LSWC - November 15, 2016
photography of the area on file with Jefferson County Department of
Community Development (JCDCD), Google Earth photography,
JCDCD critical area data base information, and U.S Fish and
Wildlife NWI maps.
2. Level II and III Assessments: Level II was used to collect easily
observable field indicators using the Washington State Wetland
Rating System for Western Washington- 2014 Update, Publication
#I 4-06-29,Washington State Department of Ecology System to
obtain a single rating for the wetland. The Level II assessment was
supplemented with Level III quantitative data collected on
vegetation, soils and hydrology on the ecosystem site. Level III
quantitative data collection was done in accordance with the
Regional Supplement to the Corps of Engineers Wetland Delineation
Manual for Western Mountains, Valleys, and Coast Region, Version
2.0, April 2008.
Pre-Exislinp- The National Wetland Inventory by the U.S. Fish and Wildlife identified
Inventories: the wetland on the Parcel 901263023 as being Palustrine Emergent
Persistent Seasonally Flooded, Partly Drained/Ditched (PEMIAd)
wetland. The wetland extends south along the west side of Center Road
to Parcel 901263017 and adjacent wetland. The wetland on the adjacent
parcel is the same classification except the USFW list it as temporarily
flooded.
As shown in Exhibit 2 on Page 5, Olympic Wetland Resources in June of
1995 classified the wetland on (Parcel 901263017) which is on the south
side of County Meadow Road as a Category (Class) III Wetland.
Actually the wetland on the south side is hydrologically connected to the
one on Parcel 901233023. Also, Wiltermood Associate, Inc. in
November 2004 identified a Category (Class) III Wetland on the west
side of Chimacum Creek on Parcel 901263020. Parcel 901263020 abuts
the northwest corner Parcel 901263023 on the east side of Chimacum
Creek. Apparently they did not check the parcel on the east side of
Chimacum Creek because all the development for that parcel was to be
on the west side of Chimacum Creek.
Welland Boundary The wetland boundary delineation was finalized once the sample plots
Delineations: were completed. The delineation of the wetland boundaries between the
non -wetland and wetlands were established by angering with a 1.25 inch
diameter screw auger. The process was to start with a known wetland
area and auger out until the non -wetland areas were found or vice versa.
All the wetland boundaries were established by augering. The
boundaries are marked with orange whips with orange ribbon stamped
with the words wetland boundary. Each whip has a station number, the
initials LSWC for Loggy Soil and Wetland Consulting and the date for
when the delineation was completed.
Ellis 901263023 LSWC - November 15, 2016
Page 15
The wetland boundary was only delineated for part of the boundary. The
boundary was marked for a distance that corresponded with the
developable area. The delineated boundary is benched mark from the
closest property corner and the flagged boundary was traversed with a
compass and chain.
An aerial photo showing the wetland boundaries and other delineated
classified wetland areas is presented in Exhibit 2.
EXHIBIT 2
PRE-EXISTING INVENTORIES
Landscan The wetland is at the base of a deposit of glacial outwash above the
alluvium floodplain. The wetland contains both slope and depressional
hydrologic and geomorphic characteristics. The slope hydrogeomorphic
(HGM) sites occupy the toe slopes at the base of the glacial outwash and
gentler slopes of the alluvium floodplain. The depressional HGM site
occupies the alluvium portion of the wetland. Exhibit 3 on Page 6 shows
the location of both HGM Classes. The wetland is bordered on the west
by Chimacum Creek. There is a ditch now classified as seasonal non -
fish stream along the east side of the wetland which drains to an un-
named fish stream at the very northeast corner of the Parcel. The
Ellis 901263023 LSWC - November 15, 2016
Page 16
wetland extends to the north to where Chimacum Creek and the non -
named fish creek converge (Exhibit 3). Chimacum Creek is deeply
incised along the parcel and the wetland between the two streams does
not appear to be flood influenced.
EXHIBIT 3
LANDSCAPE FEATURES
PRESENT PARCEL SITE CONDITIONS
Veaetation The entire wetland on the parcel except for a narrow strip on the
southeast end of the wetland is mowed on a yearly base. The
depressional HGM is mainly Phalaris arundinacea (Reed Canarygrass),
Agrostis sp. (Bent grasses) and Poa pratensis (Kentucky bluegrass. The
slope part of the wetland has dominant species of Agrostis sp., Poa
Pratensis, Phalaris arundinacea, and Ranunculus repens (creeping
Ellis 901263023 LSWC - November 15, 2016
buttercup). Identification of plants was hampered because the plants
were mowed short. There was probably a component of Lolium sp.
(ryegrasses) but was hard to identify. The dominant vegetation on the
non -wetland glacial outwash consisted of Dactylis glomerata (orchard
grass) Holcus lanatus (common velvetgrass), Plantago lanceolata (rib
plantain), Hypochaeris radicata (smooth cat's -ear), and Agrostis sp.
Soils: The Jefferson County Soil Survey was consulted for the soils. The soils
identified on the soil survey map for the wetland were Swantown and
Semiahmoo. Neither soil was present as shown on the survey map. The
wetland area had Snohomish soil. Snohomish is very deep poorly
drained silty to silty loam soils over banded layers of organic soil that is
36 inches or deeper below the soil surface. The soil survey listed the soil
on the non -wetland areas correctly as being the Everett soils and that soil
was present. The Everett soils are very deep somewhat excessively
drained gravelly sandy loams or loamy
Hydroloff: The wetland has poorly drained soils. At the time of the field
investigation there was very little moisture in the upper two feet of the
soils. There was no surface water in the depressional portions of the
wetland at the time of the investigation. During the winter the
depressional area does get shallowly inundated.' Water cannot be seen
because of the height of the vegetation but it can reach ankle height in
most years. The slope wetland is probably seasonally saturated but is
sloped enough not to be inundated.
Wetland Determination A total of four (4) study plots were established, three (3) on the wetland
and Wetland Ratinand one (1) on the non -wetland area. The location of the study plot sites
are indicated in Exhibit 3 and identified as P1 thru P4. The quantitative
field data sheets for the four (4) plots are presented in Appendix I. The
wetland rated as Category III Wetland. Since the wetland has both slope
and depressional conditions the wetland is required to be rated as a
depressitmal HGM? I also rated the wetland using the Slope HGM
which also rated the wetland as a Category 11I. The classification rating
sheets can be reviewed in Appendix II. Table 1 below provides
summary of wetland rating data using the depressional HGM as the main
HGM rating. The slope HGM rating is provided in the table for
comparison. Location of the wetland study plot sites were recorded by
latitude and longitude and are presented in the field data forms in
Appendix I.

Compiled Wetland Information on Parcel 901263023
Buffer: The wetland requires a 110 feet wide buffer based Jefferson County
Code (JCC) Table 18.22.330 (2). The buffer width of 110 feet is shown
in the wetland delineation drawing in Appendix III. Only those wetland
stations required to establish the buffer boundary width need to cover the
proposed development area were established. Buffers were measured
with clinometer and tape and corrected for slope using a table to convert
slope distances to horizontal distances. Horizontal distances were round
up to the nearest foot. The buffer is temporary marked with orange
colored whips indicating a station for the buffer boundary.

HGM Classification of Wetlands in Western Washington
For questions 1-7, the criteria described must apply to the entire unit being rated.
If the hydrologic criteria listed in each question do not apply to the entire unit being rated, you
probably have a unit with multiple HGM classes. In this case, identify which hydrologic criteria in
questions 1-7 apply, and go to Question 8.
1. Are the water levels in the entire unit usually controlled by tides except during floods?
NO-goto2 M.
1.1 Is the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)?
NO - Saltwater Tidal Fringe (Estuarine)
if your wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it
is Saltwater Tidal Fringe it is an Estuarine wetland and is not scored. This method cannot be used to
score functions for estuarine wetlands.
2. The entire wetland unit is flat and precipitation is the only source (>90%) of water to it. Groundwater
and surface water runoff are NOT sources of water to the
NO-goto3
Ifyour wetland can be classified as a Flats wetland, use the form for Depressional wetlands.
3. Does the entire wetland unit meet all of the following criteria?
_The vegetated part of the wetland is on the shores of a body of permanent open water (without any
plants on the surface at any time of the year) at least 20 ac (8 ha) in size;
_At least 30% of the open water area is deeper than 6.6 ft (2 m).
NO-goto4
4. Does the entire wetland unit meet all of the following criteria?
X The wetland is on a slope (slope can be verygradual),
X The water flows through the wetland in one direction (unidirectional) and usually comes from
seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks,
X The water leaves the wetland without being impounded.
YES - The wetland class is Slope See notes p4
NOTE: Surface water does not pond in these type of wetlands except occasionally in very small and
shallow depressions or behind hummocks (depressions are usually <3 ft diameter and less than 1 ft
deep).
5. Does the entire wetland unit meet all of the following criteria?

NOTE: The Riverine unit can contain depressions that are filled with water when the river is not
flooding
6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the
surface, at sometime during the year? This means that any outlet, if present, is higher than the interior
of the wetland.
NO-goto7
7. Is the entire wetland unit located in a very flat area with no obvious depression and no overbank
flooding? The unit does not pond surface water more than a few inches. The unit seems to be
maintained by high groundwater in the area. The wetland may be ditched, but has no obvious natural
outlet.
YES - The wetland class is Depressional See notes
8. Your wetland unit seems to be difficult to classify and probably contains several different HGM
classes. For example, seeps at the base of a slope may grade into a riverine floodplain, or a small
stream within a Depressional wetland has a zone of flooding along its sides. GO BACK AND IDENTIFY
WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT
AREAS IN THE UNIT (make a rough sketch to help you decide). Use the following table to identify the
appropriate class to use for the rating system if you have several HGM classes present within the
wetland unit being scored.
NOTE: Use this table only if the class that is recommended in the second column represents 10% or
more of the total area of the wetland unit being rated. If the area of the HGM class listed in column 2
is less than 10% of the unit; classify the wetland using the class that represents more than 90% of the
total area.
