I. fntroduction
Marine Surveys & Assessments (MSA) was authorizedby the applicant and property owner,
David Cohn, to assess four wetland areas over ten parcels Jefferson County, Washington. For
ease of identification, the wetland areas are designated 1-4 (Figurel), and will be referred to by
these identifying numbers thoughout this reporfi wetlands 1-3 lie within the limits of the City of
Port Townsend, and wetland 4lies just outside. Wetland I and2 were both delineated, rated, and
assigned buffers; Wetland 3 was rated and assigned a buffer; Wetland 4 was mapped and
assigned a buffer. Wetlands 1-3 were assigned buffers based on City of Port Townsend code;
wetland 4 was assigned a buffer based on Jefferson County code. All field work was completed
between August 11th and August 22"d,2016, with GIS, aerial photography, and subsequent report
writing completed in September 2016.
The property is located at3057 7th St, Port Townsend, WA, and consists of ten parcels which
equal approximately 77.0 acres. Parcel numbers are: 001093002, 001093004, 001093001,
997000101, 99700020t,997000701,997000301,997000601,997000401,997000501. The
parcels are located in the SW 1/4 SEC 9, T30N, RlW (Figure 1).
II. General Site Conditions
This property is mostly open farmland located within a relatively residential and developed
section of east Jefferson County on Quimper Peninsula. It is west-southwest of Port Townsend,
WA by approximately 2.4 miles, and west-northwest of Port Hadlock, WA by approximately 5.0
miles. The property is 77 .0 acres and is divided into ten parcels, the vast majority of which is
open, having been logged and farmed years ago. There is a small farmhouse in the central-
western section of the property, along with a small outbuilding and large barn, accessed from the
east via 7th Street, off Discovery Road (Figure 1).
To the north, the property is bordered by forested land, while the west and southwest is bordered
by residential neighborhoods, accessed in large part from South Jacob Miller Road. To the east is
Discovery Road, a major town artery. Generally, the elevation along the northern section of the
property is greater than the southern; drainage on the property flows from north-to-south. The
westem quarter, approximately, consists of a wetland corridor running from the northwest comer
of the property southeast to the man-made pond on the southern border.
Four wetland areas were identified on the property. The smallest (Wetland 1) is approximately
0.10 miles northwest from the farmhouse; the next largest in size (Wetland 2) is almost
immediately adjacent to the farmhouse to the northeast; to the southeast by approximately 0.07
miles lies the next largest wetland (Wetland 3), while the largest, being the aforementioned

EM: Class Emergent Wetland: charactenzed by erect, rooted, herbaceous hydrophytes,
excluding mosses and lichens. This vegetation is present for most of the growing season
in most years. These wetlands are usually dominated by perennial plants. All water
regimes are included except subtidal and irregularly-exposed.
F: Water Regime Semi-Permanently Flooded: surface water persists throughout the
growing season in most years. When surface water is absent, the water table is usually at
or very near the land surface.
L: Subclass Persistent: Dominated by species that normally remain standing until the
beginning of the next growing season. This subclass is found only in the Estuarine and
Palustrine systems.
SS: Class Scrub-Shrub: Includes areas dominated by woody vegetation less than 6m (20
feet) tall. The species includes shrubs, saplings, and trees of stunted growth form dues to
environmental conditions.
C: Water Regime Seasonally Flooded: Surface water is present for extended periods
especially early in the growing season, but is absent by the end of the growing season in
most years. The water table after flooding ceases is variable, extending from saturated at
the surface to a water table well below the surface.
o
The NWI map documents were prepared primarily by stereoscopic analysis of high altitude
aerial photographs taken in 1980 and 1981. Wetlands were identified on the photographs based
on vegetation, visible hydrology, and geography. The aerial photographs typically reflected
conditions during a specific year and season when they were taken. Some small wetlands and
those obscured by dense forest cover may not be included on the map. Lr addition, there is a
margin of error inherent in the use of aerial photographs. As you will see in our delineation
results, the actual Cowardin classification of the wetlands found differed from those on the
USFWS NWI map.
IV. Wetland Assessment Methods
Consistent with procedures detailed in the Washington State Wetlands Identification and
Delineation Manual (\|/ashington State Department of Ecologlt, 201I Manual),preliminary
information was gathered on the project site prior to the field review, rating and delineation.
General information sources included:
Swanson Farm (3057 7th St, Port Townsend WA) Wetland Report sIMSA
V. Wetland Delineation
Wetland delineation establishes the existence (location) and physical limits (size) of a wetland
for the purposes of federal, state, and local regulations. In determining these physical parameters
of each individual wetland, indicators of vegetation, soils, and hydrolo gy are analyzed to assess
critical areas. By defining the transition zotte between scientifically established upland and
wetland indicators, an established accurate boundary of the wetland can be identified between a
pair of data points; one representing the upland and one representing the wetland. It is common
for paired data points, when linked to vegetative indicators (such as an obvious transition line of
upland gtass into an emergent herbaceous community), to inform the identification of the
wetland delineation. A delineation, often in conjunction with a subsequent rating, is a necessary
procedural step in obtaining information which will inform subsequent construction.
Of the four wetlands found on the property, two were delineated. Wetland I and 2 were
delineated for reasons of potential future construction; the property owners identified these
locations as potential building spots, and therefore opted to obtain more accurate wetland
bonndaries. Wetland I and2,both classified by the US Fish and Wildlife National Wetlands
Inventory as PEMF (Semi-permanently Flooded, Palustrine, Emergent Marsh), were delineated
using standard paired wetland test plots. Wetland 1, which was smaller and more homogeneous
of border, was delineated using two paired test plots. Wetland 2, which was slightly larger and
also more heterogeneous of border, was delineated using four paired test plots.
Each test plot consisted of trwo data points, designated "Dry" and o''Wet". Each data point
consisted ofa test pit dug to standard depth of 16 inches, to expose a representative soil profile.
Each data point was then assessed for the presence of three wetland indicators: hydrophytic
vegetation, hydric soils, and wetland hydrology. Following the successful location of paired data
points, flagging was hung between data points to mark the wetland boundary. The test pits at
each data point were marked with yellow flagging, pink wire flags, and GPS latitude and
longitude was taken.

1. Vegetation
In an effort to distinguish the types of plants that grow in different hydrologic regimes, the U.S.
Fish and Wildlife Service incorporated a system of wetland plant indicator status to classifu
individual plant species. The wetland indicator status of a species is based on the individual
species occurrence in wetlands in 13 separate regions within the United States. A plant indicator
Swanson Farm (3057 7th St, Port Townsend WA) Wetland Report TIMSA
Hydric soils are soils that formed under conditions of saturation, flooding, or ponding long
enough during the growing season to develop anaerobic conditions in the upper soil horizon
(NRCS). Most hydric soils exhibit characteristic morphologies that result from repeated periods
of inundation or saturation that last more than a few days. Saturation or inundation, when
combined with microbial activity in the soil, causes a depletion of oxygen. This anaerobic state
promotes certain biogeochemical processes, such as the accumulation of organic matter, the
accumulation or reduction of iron, and other reducible elements.
These processes in turn create regionally specific, visible indicators, which help identify and
delineate hydric soils in a field setting. These indicators are not intended to replace or modify
the requirements contained in the definition of a hydric soil; they are dynamic, and open to a
degree of human interpretation. Some hydric soils lack any currently listed and accepted
indicators; therefore, the lack of any listed indicator does not prevent classification of a particular
soil as hydric. However, such soils and their specific morphologies, are included and specified in
the necessary field guides.
In this wetland, hydric soils were identified using the 2013 Pocket Guide to Hydric Soil Field
Indicators,prepared by the Wetland Training Institute, Inc, in conjunction with the Munsell Soil
Color Book, a standard reference manual prepared by the Munsell Color Company and used by
the United States Department of Agriculture. Wetland test plot soil findings are as follows:

The intent of a rating is to provide a basis for protecting and managing wetlands; this rs
accomplished assessing a wetland's valued functions and resources -- ecological, economic, or
aesthetic. In the process of a rating, a wetland is given a score according its comparison to
standardized categories and specific attributes such as rarity, sensitivity to disturbance, and the
functions they provide. Based upon this score, the wetland is then placed in Category 1 through
Category 4; the forrner is a wetland of greatest value, based upon the rating rubric's
characteization of its inherent value, while the latter is a wetland of least value. A specific
buffer, identified in accordance with each individual wetland's rating score, is then
recommended, using standardized and established guidelines. While all wetlands provide some
functions and resources that are valued, be they ecological, or aethestic, they also vary widely;
consequently, the recommended buffer, identified in accordance with each individual wetland's
rating score, reflects that particular wetland and its specific qualities.
Of the four wetland areas investigated on the property, each one was determined to fall into the
class of Depressional. According to the lil'ashington State f4/etland Rating Systemfor Western
Washington 2014 Update (Hruby z}L4),Depressional wetlands occur in topographic depressions
where the elevation of the surface within the wetland is lower than in the surrounding landscape.
The shapes of Depressional wetlands vary, but in all cases, the movement of surface water and
shallow subsurface water is toward the lowest point in the depression. The depression may have
an outlet, but the lowest point in the depression is somewhere within the boundary, not at the
outlet.
The wetlands were rated using the Washington State Wetland Rating Systemfor Western
Washington (2014 Update). When the final wetland category is determined, it is based on either
functions or special characteristics (whichever is higher). The rating system for special
characteristics was designed to differentiate among wetlands based on their sensitivity to
disturbance, their significance, their raity, the ability to replace them and the functions they
provide. Wetlands identified with special characteristics are rated by function in addition to
special characteristics because in some cases there are additional buffer widths due to a very high
score in one of the three functions listed below.
In accordance with Jffirson County Code, Table 18.22.330(3), Wetland Categories, Rating
Scores and Buffer llidths, rating categories are divided into four grades, in order of descending
buffer size: Category I with total scores of 23-27; Category II with total scores of 20-22;
Category III with total scores of 16-19; Category IV with total scores of 9-15.
The category of wetland based on functions is rated by the following parameters:
1) Water Quality Functions: a wetland's potential to improve water quality
a) Potential of the wetland to improve water quality of and surrounding the wetland.
b) Potential of the wetland to support the water quality function of and surrounding the
wetland. (This parameter regards the ability of the wetland to mitigate for and lessen
the toxicity of potential pollutants on and surrounding the wetland).
Swanson Farm (3057 7th St, Port Townsend WA) Wetland Report 13 lMSA
Special Rating characteristics within the wetland and its associated 330 foot surroundings, the
wetland was rated, based on its functions, to be a Category IV Depressional wetland (Appendix
A; Data Forms)
As the property owners have expressed interest in the northem central section as a possible
building site, and as Wetland 2 currently abuts the existing single farmhouse, the buffer was
established using City of Port Townsend Municipal Code 19.05.110(E) for moderate impact land
uses (single-family residential use on parcels larger than one acre) at 40 feet (Figure 1). As
defined earlier in this report, Wetland 2was also delineated; this delineation boundary was used
to establish the baseline for the 4O-foot buffer.
Wetland 3 - Rated Category lV - Buffer of 60 Feet
This wetland, which is found in the National Wetlands Inventory @igure 2), is approximately
1.48 acres. It is relatively elongate in shape, running from northwest-to-southeast and its
boundary is relatively homogenous. The southem portion of this wetland is approximately 30
feet from 5th Street, a neighboring residential road, as well as being approximately 100 feet from
a neighboring single-dwelling home. According to aerial photographs and satellite images from
the past, this area is generally wetter than Wetlands 1 and 2; the southern property line is
generally lower in elevation than the northern property line, and topography slopes in a generally
southeast direction. As there are no Special Rating characteristics within the wetland and its
associated 330 foot surroundings, the wetland was rated, based on its hrnctions, to be a Category
IV Depressional wetland.
Given the location of Wetland 3, this buffer was established according to the City of Port
TownsendMunicipalCode 19.05.110(E) (updated forusewiththe 2014ratrngsystem) forhigh
impact land use wetlands without a delineated boundary (single-family residential use on parcels
larger than one acre; public roads) at 50 feet (Figure 1); an additional 10 feet was added to this
buffer based to reach the slightly more conservative buffer of 60 feet recommended by Jefferson
County Code table 18.22.330(2). The boundary for this wetland buffer was found using field
vegetative indicators, aerial photography, satellite imagery, and GPS.
Wetland 4 - Unrated at Property Owners Request - Buffer of 350 Feet
This wetland is approximately 4.55 acres. It is relatively elongate in shape; located in the westem
l/Sth of the property, it runs approximately northwest-to-southeast. A smaller wetland, along
with a freshwater pond, is found in the National Inventory of Wetlands. Upon field research and
examination of aerial photographs and satellite images, MSA wetland specialists determined that
the smaller wetland and the freshwater pond are hydrologically contiguous, and form the ends of
alargv wetland corridor (4.55 acres). The southeastem end of this wetland abuts the southern
property line; the northwestern end abuts the northwestem property line. According to aerial
photographs, satellite images, and topographical maps, flow moves in a generally southeast
direction. The area is generally agricultural grassland, with scattered scrub-shrub forest.

HGM Classification of Wetlands in Western Washington
1 water levels in the entire unit usually controlled by tides except during floods?
gotoZ YES - the wetland class is Tidal Fringe - go to 1.1-
1.1 Is the salinity ofthe water during periods of annual low flow below 0.5 ppt [parts per thousand)?
NO - Saltwater Tidal Fringe (Estuarine) YES - Freshwater Tidal Fringe
If your wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it
is Saltwater Tfdal Fringe it is an Esfitarine wetland and is not scored. Thls 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
surfuce water runoff are NOT sources of water to the unit'
goto3 YES - The wetland ciass is Flats
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 ffiteria?
_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] ln size;
least 30% of the open water area is deeper than 6.6 ft [2 m].
goto4 YES - The wetland class is Lake Fringe [Lacusffine Fringe)
+.the entire wetland unit meet all of t]le following criteria?
-The
wetland is on a slope {slope can be very gradua[),
_The water flows through the wetland in one direclion [unidirectional) and usually comes from
seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks,
water }eaves the wetland without being impounded.
goto5 YES - The wetland class is Slope
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
deepJ.
5. Does the entire wetland unit meet all of the foliowing *iteria?
-The
unitis ir ava)ley, or sffeam channel, where if gets inundated by overbankfloodingfromthat
stream or river,
_The overbank flooding occurs at least once every Z years.
