CRITICAL AREA DETERMINATION, DELINEATION & CLASSIFICATION:
Section 404 of the Clean Water Act Define Wetlands as:
"Wetlands are areas that are inundated or saturated by surface or ground water at a
frequency and duration sufficient to support, and that under normal circumstances do
support, a prevalence of vegetation typically adapted for life in saturated soil conditions.
Wetlands generally include swamps, marshes, bogs, and similar areas." - Definition of
wetlands as used by the U.S. Army Corps of Engineers (Corps) and the U.S.
Environmental Protection Agency (EPA) since the 1970s for regulatory purposes.
Wetlands must meet three parameters to be a wetland: Hydrophytic Vegetation (FAC or wetter),
Hydric Soils (i.e. redoximorphic features in the upper ten inches of soil profile) and Hydrology
(ponding or saturated soils).
METHODOLOGY:
Level I Assessment consisted of reviewing existing information to develop background knowledge
of physical features, and to identify the potential for wetland and other water occurrences on the
subject parcels. The resource documents available for the Level I preliminary assessment included:
USDA Soil Conservation Service (SCS), "Soil Survey of Jefferson County Area Washington”,
aerial photography, Jefferson County Critical Areas Maps and Jefferson County Critical Areas
18.22 Article VII Wetlands, U.S Fish and Wildlife NWI maps. See Appendix A “Jefferson County
Critical Areas Map” for mapped wetlands on and around subject parcel.
Level II Assessment consisting of on-site investigation was conducted to determine if a wetland
area existed and collected quantitative data of Vegetation, Soils, and Hydrology as recommended in
accordance with the 1987 Corps of Engineers Wetlands Delineation Manual and the Regional
Supplement to the Wetland Delineation 1987 Manual for Western Mountains, Valleys, and Coast
Region (Version 2) 2010.

PURPOSE OF THIS WETLAND INVESTIGATION:
I was contacted by Jann Hagan to conduct a preliminary wetland investigation. Jefferson County
online critical areas map shows a wetland that runs from the east side of Chimacum Road that
extends over Chimacum Road onto the subject parcel’s east property line. The proposed project is to
construct a ADU and garage for their aging parents to reside in. The current site plan shows a
footprint that is 1,249 square feet. The location is in their mowed area that is easterly portion of the
parcel, west of Chimacum Road.
EXISTING CONDITIONS:
Area of mapped wetland is flat. There is a roadside ditch next to Chimacum Road which was dry
during every site visit. Even after two days of very heavy rain fall. The ditch is 250’ long by 7’
wide. It was dominated with upland vegetation. Moving west, over the east property line it rises up
in elevation where there is a row of fruit trees growing. Area was heavily vegetated with common
dandelion ( Taraxacum officinale, FACU) oxeye daisy (Leucanthemum valgare, FACU) and purple
deadnettle ( Lamium purpureum , UPL). The west portion of the parcel slopes upward, west, to the
existing home and shop. The lower, east side, is flat with prairie plants and grasses that is routinely
mowed. This is the projected home site. See below for approximate location:

FIELD INVESTIGATION:
There were two data plots analyzed. There is one write up in Appendix B because the soil profiles
were the same. One was to monitor the hydrology. The location of the monitored pit is in the photo
below. The reasoning for choosing the location was because after heavy rains, the ditch was dry and
the only area exhibiting hydrology was in two five foot in diameter patches on the north end of the
field. Assuming this would be the worst case scenario, this pit was monitored after the rains. It was
dry down to sixteen inches three days later. Three days later, the water had completely filtered down
through the gravelly sandy loams. If the area had hydric soils, it would be an area of less than ten
feet in diameter. Due to all the disturbance surrounding the area, it would be a un regulated Cat IV
less than four thousand square feet. Please see field photo below:

Vegetation:
Most of the mowed field/pasture was dominated by common dandelion (Taraxacum officinale,
FACU) oxeye daisy (Leucanthemum valgare, FACU) black medick (Medicago lupulina, FACU)
with occasional amounts of purple deadnettle (Lamium purpureum, FACU). Hydrophytic vegetation
was not present. The roadside ditch was the only place where poisonous hemlock (Conium
maculatum, FAC) was growing. Very small patch near the south end of the ditch near the driveway.
The rest of the vegetation in the ditch was those mentioned above growing in the mowed pasture.
Please see below showing the majority of the vegetation on the subject parcel and in the roadside
ditch:

Mapped Soil Series:
The NRCS mapped the eastern one quarters of the parcel near Chimacum Road as the Wapato silty
clay loams. The soil series is very deep and poorly drained. It is usually on flood plains. The
Wapato is a hydric soil. The soil series was not found on the parcel. The soil series most likely
exists east of Chimacum Road near Chimacum Creek.
The NRCS mapped soil series is the San Juan gravelly sandy loam on the west three quarters of the
property. These soils are somewhat excessively well drained formed in eolian sands over glacial
outwash.
Two soil pits were analyzed:
Field Data Plot Write up in Appendix A: Soils had 10YR2/2 sandy loams. The lower horizon, 4-
14 inches, is 10YR3/3 gravelly sandy loams. No redoximorphic features and no oxidized roots.
Below that turns in gravelly medium sands.
Another soil pit was “monitored”. It was located in the northeast corner of the parcel. There were
two depressions approximately five feet in diameter that had water on the surface from heavy rains.
Matrix and chromas were exactly like the one above that was written up. Hydrology was coming in
at eight inches. Following day, dug another pit close to it. Water was down to fourteen inches. On
Third day the water had moved out and soil was dry. Please see below for JCCD mapped soil series:

Hydrology:
No hydrology present in the upper fourteen inches of the data plot.
CONCLUSION:
No wetlands exist on the subject parcel. There is a high quality wetland east of Chimacum Road that is
associated with Chimacum Creek, a fish bearing stream. The buffers would not extend over Chimacum Road
onto the subject parcel. It is separated from the wetland by the road which has impervious surfaces and heavy
traffic. This is not a final determination. Jefferson County Community Development with have the final
decision.

Wetland Determination
Two levels of information were gathered to do a routine wetland determination.
These included:
a) Review of preliminary site data and,
b) On-site investigation to determine the presence of wetlands and non-wetland
waters.
a) A review of existing information was conducted to develop background knowledge of
physical features, and to identify the potential for wetland occurrence on the subject
property. The resource documents available for preliminary review of the site
conditions included: USDA Soil Conservation Service (SCS), "Soil Survey of
Jefferson County Area Washington", 2013 and 1994, Jefferson County aerial
photography, and Jefferson County Planning Department data.
b) During the on-site investigation, wetland areas were determined and verified on the basis of
three parameters: Hydrophytic Vegetation, Hydric Soils, and Wetland Hydrology, as recommended
in the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Western
Mountains, Valleys and Coast Region (Version 2.0), May 2010. Hydric soils are classified using
Filed Indicators of Hydric Soils in the United States, Version 7.0, 2010.
A positive wetland determination is made when all three parameters are present, or in certain
situations determined following the guidelines recommended in wetland determination procedures,
or for atypical situations or problem areas.
c) The wetland was classified as to type (category) by using the Washington State wetland
rating system for western Washington-October-2014. Effective January 2015, Washington State
Department of Ecology’s Publication No. 03-06-029 and applicable Rating Forms Effective January
1, 2015.
Hydrophytic Vegetation
Areas where more than 50% of the dominant species present from all strata are hydrophytes
(plants adapted to growth and reproduction in saturated soil conditions) are considered to be inside
the wetland boundary, unless clear evidence of hydric soils or wetland hydrology cannot be
established. A species is considered dominant if it is equal to or greater than 20% areal cover, or
exerts a controlling influence on, or defines the character of a community. Hydrophytic vegetation
is determined to be present, when under normal circumstances:
More than 50% of the dominant plant species in a plant community have an indicator category of
Obligate Wetland (OBL), Facultative Wetland (FACW), and/or Facultative (FAC) as listed in
"National List of Plant Species that Occur in Wetlands: Northwest (Region 9)”

This Plant Indicator Status Categories system was developed for the USFWS National Wetlands
Inventory by Cowardin et al. (1979). The National Plant List Panel, Reed, Porter B., and Jr.
modified it in 1988 and 1993. The Wetland Indicator Category (WIC) used in this report refers to
the plants Indicator Symbol as referred to in the table below. There have been changes to the list
since 1993. In 2016 the list was updated and was used for this report.

Hydric Soils
There have been tremendous scientific changes since 1991 in several of the indicators such as the
introduction of aquic conditions to cover the requirements for saturation, reduction, and

Wetland Hydrology
Water is the driving force for wetlands. Indications of wetland hydrology are those where
the presence of water has an overriding influence on characteristics of vegetation and soils due to
anaerobic and reducing conditions, respectively.
Areas that are seasonally saturated and/or inundated to the surface for a consecutive number
of days for more than 12.5% of the growing season are wetlands provided the soil and vegetation
parameters are met. Areas wet between 5% and 12% of the growing season in most years may or
may not be wetlands. Areas saturated to the surface for less than 5% of the growing season are non-
wetlands. Wetland hydrology exists if field indicators are present.
Field indicators of wetland hydrology may include, but are not limited to visual observations
of inundation, ponding, soil saturation, oxidized root channels (rhizospheres) associated with living
roots and rhizomes, watermarks, drift lines, water-borne sediment deposition, or wetland drainage
patterns.
The growing season starting and ending dates are required to evaluate hydrologic data. For
wetland determinations, the growing season is determined using the local SCS county soils surveys.
Generally, the growing season is calculated based on the "28 degrees F or lower" temperature
threshold at a frequency of "5 years in 10". For much of western Washington at low elevations, the
mesic growing season (March 1 to October 31) has been considered a good rule. However, in some
areas of the Puget Sound Lowlands and coastal areas the growing season occurs all year round
because the soil temperature at 19.7 inches below the soil surface is higher than 41 degrees F.
