Re: Wetland Delineation and Categorization for the 1.76 acre parcel (TPN 721162001)
located on North Beach Drive in the Bridgehaven Development, Port Ludlow,
Jefferson County, Washington. This parcel is Government Lot 1 in Section 1, T 27
N, Range 1 W. WM. Jefferson County Department of Community Development
Case # MLA06-0496.
Dear Robert:
The wetland delineation was conducted on November 3, 2006 to' mark the wetland
boundary on the above referenced parcel. The delineation was conducted using the
Department of Ecology, Washington State Wetlands Identification and Delineation Manual
(Publication #96-74), as required by Section3-Land Use Districts-of the Jefferson County
Code. This manual utilizes the three parameter methodology to determine the presence or
absence of wetlands. The three parameters include wetland hydrology, hydric soil, and
hydrophytiC vegetation and positive indicators of all three wetland parameters must be
present for an area under normal circumstances to be considered wetland. The use of this
manual and the three wetland parameter methodology on this parcel revealed that the site is
under normal circumstances so the Routine On-Site Determination Methodology was used
to delineate the on-site wetland.
The parcel for whiCh this delineation was completed is located at the south end of the
Bridgehaven channel, which is formed by the heavily developed sand spit on the east side.
It is bordered to the south and west by North Beach Drive, to the north by Bridgehaven
channel and a single family home to the east. There is a rapidly eroding channel on the east
side of the property around the culvert that conveys water from estuarine wetland to the
south (off-site south of North Beach Drive) into Bridgehaven channel. The parcel is
generally level at the south end but is steeply sloping along the northern extension. The
level area appears to have been created in historic fill and represents the only buildable area

on this property . The steep slopes extend up to North Beach Drive and Soutb Point Road
and end at the west edge of Bridgehaven Channel. The sloping portion is dominated by a
forested community having a canopy of coniferous and deciduous trees and a thick shrub
layer. The level area is open grassland and the vegetation is dominated by a mixture of
grasses, weeds and invasive shrubs with a few conifer trees on the west and east ends.
The Bridgehaven Channel is considered an estuari~ c;ommunity because it is enclosed by a
narrow spit and it is generally composed of open'water with exposed saltmarsh along the
upper edges and mudflat throughout at low tide.' The vegetated saltmarsh contmunity
occupies the upper limit of tidal saltwater along the north edge, of this property and along
the ,entire west edge of the channel. This community is dominated by saltgrass with lower
percentages of Douglas aster, seaside arrowgrass, pickh~weed and Lyngby's sedge. The
saltmarshcommunlty extends northerly along the west edge of Bridgehaven Channel and
the upland forest vegetation overhangs from the upland slope. The channel itself appears to
be dredged to maintain water deep enough to facilitate boat travel to docks adjacent to many
of the single family homes.
The delineation was conducted around the upper limits of the saltmarsh community
beginning at the east property line and extending to the west property to identify the limits
of both the estuarine and palustrine wetland communities on this parcel. The estuarine
wetland meets the criteria for a Category II system according to the revised Washington
State Wetland Rating System (DOE publication #04-06-025) because it is an estuarine
system that only meets 1 of the 3 criteria listed in question SC 1.2 of the rating form. The
wetland also meets the criteria for a Category II estuarine wetland using the 1993
Washington State Wetlands Rating System (DOE Publication #93-74). The Jefferson
County Critical Areas Ordinance (CAO) requires a 100 foot buffer for Category II wetlands
to be measured horizontally from the delineated wetland boundary. The buffer and wetland
encompass all of the property so a buffer reduction is necessary to accommodate the
proposed single family home, which will be positioned at the south edge of the property as
shown on the attached site plan. A buffer enhancement is required as compensation for the
Lingenbrink

buffer reduction so that the reduced buffer functions as good as or better than the buffer at
the required width. This letter has been prepared to describe the delineated wetland in detail
with respect to the data collected in the field, the wetland category and'the required buffers.
It also includes a brief description of the single family project and the buffer reduction
necessary to accommodate the home. It also includes.background information provided by
the Kitsap County Soil Survey, NationalWetlands Inventory and the Jefferson County
website. The buffer enharicement plan is described in a separate document.
The on-site soils are mapped as CfC Cassolarysandy loam, 0-15 % percent slopes on the
west edge, Lu Lummi silt loam on the east side, and Td Tidal mar~h across the middle,
according to the Soil Conservation Service (now the National Resources Conservation
Service), Soil Survey of Jefferson County Area, Washington, August 1975. Cassolary soils
are not classified as hydric and do not contain inclusions of hydric soil types. Lummi and
Tidal marsh soils are classified as hydric and are.mapped all along the channel area as well
as across the east halfof this parcel. The parcel was likely filled historically to create a
building pad and there are no hydric soil conditions remaining in this area. See enclosed
map for site located on the soil survey and see enclosed soil descriptions for additional
information on the mapped soils.
The US Fish and Wildlife Service (USFWS), National Wetlands Inventory (NWI), Lofall
Quadrangle, maps and classifies the Bridgehaven Channel as Estuarine, Subtidal,
Unconsolidated bottom, Subtidal, which is the same classification given to Hood Canal.
Estuarine, Intertidal, Emergent, Regularly and Irregularly flooded wetlands are mapped off-
site to the south across North Beach'Road from this parcel. The Jefferson County Critical
areas mapping indicates a large wetland extending south along the Bridgehaven Spit and
across the east edge of this parcel. The wetland mapping extends south along South Beach
Drive to South Point Road. See enclosed maps for site located on the NWI and Jefferson
County Critical Areas Map.

The south edge of the wetland is delineated beginning at the large scoured area on the east
side and extending to the North Beach Road in order to identify the boundary of both the
estuarine and Palustrine wetland communities. Data was collect~d at three test holes, one in
each of the wetland communities and one within the proposed building area to verify the
wetland delineation and to document wetland and upland conditions. At each test hole, a
16~inch soil pit was completed to document the presence or absence of hydriC (wetland) soil
conditions (dark soil colors with or without mottling) and the presence or absence of
wetland hydrology indicators (indicators include standing water on surface orin test hole;
surface scouring; water stained vegetation; drift lines; and/or oxidized root channels in the
soil). In a 3D-foot diameter circle around these test holes, the dominant vegetation is
recorded in order to determine whether or not the hydrophytic vegetation criterion is met.
If there is greater than 50 % cover by plants having, indiCator status of F AC. (34-66 % of the
time in wetlands-equally likely in wetlands and uplands); FACW (67-99% of the time in
wetlands); and/or OBL(greaterthan 99% of the time in wetlands), then the hydrophytic
vegetation criteria is met. See attached drawing for approximate location of the test holes
and Data Forms.
The palustrine forested wetland community was sampled ,at Test Hole 1. The vegetation
community is dominated by a canopy of red alder (Alnus rubra) F AC with lower
percentages of Pacific willow (Salix lucida, ssp. lasiandra) FACW and Sitka willow (Salix
sitchensis) F ACW. The shrub layer is dominated by Himalayan blackberry (Rubus
armeniacus) FACU with lower percentages of black twin berry (Lonicera involucrata)
FAC+ and the herbaceous layer is dominated by horsetail (Equisetum arvense) FAC and
cattail (Typha latifolia) OBL. The soil test hole conducted in this area revealed the
presence of a two layer profile consisting of a 7 inch mucky sandy loam surface horizon
that has a matrix chroma of 10 YR 2/1 over a sandy soil that has a matrix chroma of 10 YR
4/1. Hydrology was present during the field delineation as soil saturation to the surface of
the soil hole. Seeps and springs provide most of the hydrology for this area of wetland

although it is also likely fed by , runoff from North Beach Road and South Point Road' both
of which lie above the wetland. Water flows easterly down the slope and into Bridgehaven
channel.
Test Hole 2 is located in the estuarine emergent wetland community where the vegetation is
dominated by typical saltmarsh species including saltgrass (Distich lis spicata)OBL;
pickleweed (Salicomia virginica)OBL; and saltmarsh plantain (Plantago maritima) OBL
with lower percentages of salt tolerant cattail (Typha angustifoliilm) OBL. There are upland
shrubs overhanging the saltmarsh in the area sampled including Scot's broom (Cytisus
scoparius)FACU; ocean spray (Holodiscus discolor) UPL; salmoIl.berry (Rubus spectabilis)
FAC and thimbleberry (Rubus parviflorus) FACU. The soil test hole revealed a low
chroma sand to a depth of 16 in.ches that is inundated at least twice a day by tidal saltwater.
The area was flooded during the field visit and there was at least 4 inches of standing water
present in the saltmarsh area. The areas sampled at Test Holes 1 and 2 are determined to
be jurisdictional wetland because there are positive indicators. present for all three wetland
parameters.
TestHole 3 is located in the proposed homesite near the upland forest edge. The forest
canopy contains a mixture of western red cedar (Thuja plicata) FAC and bigleaf maple
(Acer macrophyllum) FACU with lower percentages of grand fir (Abies grandis) FACU.
The shrub layer is dominated by Himalayan blackberry (R. armeniacus) F ACU and
salmonberry (R. spectabilis) FACand the herbaceous layer is dominated by tall fescue
(Festuca arundinacea) FAC- with lower percentages of horsetail (E. arvense) FAC. The
soil test hole revealed a two layer profile consisting of a 3 inch sandy loam surface horizon
that has a matrix chroma of 10 YR 3/2 and a sandy subsurface horizon that has a matrix
chroma of 10 YR 4/3. Hydrology was not present during the field visit and there was no
evidence of wetland hydrology. The area sampled at Test Hole 3 is non-wetland or upland
because it lacks positive indicators for all three wetland parameters.

Section 3-Land Use Districts of the current Jefferson County Unified Development code
requires the use of the Department of Ecology's Wetland Rating Wetlands Rating System
for Western Washington but they will be switching to the 2004 Wetland Rating System for
Western Washington upon adoption of their new critical areas ordinance. The wetland has
been rated using both systems so that the appropriate regulations can be applied. The
wetland identified as the Bridgehaven Channel meets the criteria for a Category II system
using both rating systems (rating forms attached), because it is an estuarine system that is
heavily disturbed and lacks features associated,with Category I estuarine wetland systems
A 100 foot buffer is required from the delineated boundaries of Category II wetlands with a
5 foot building setback from the buffer edge according to the current Jefferson County
Critical Areas Ordinance (Section 3.6.9, Table 3-4 Standard Buffer Widths for Wetlands).
The future buffer widths was not known at the time this report was prepared but if the new
ordinance follows the buffer widths established in adjoining jurisdictions, the buffer will be
at least 100 feet for Category II estuarine wetlands. The required width of the buffer in the
new CAO is moot because this site is composed entirely of wetland and buffet and a
reduction is necessary to construct a single family home at the south end. The wetland
bUffer is measured horizontally from the delineated wetland edge and is to remain in
existing or native vegetation. Buffer reductions are permitted where an applicant can show
that the standard buffer width averaging is unfeasible and the project application includes a
buffer enhancement plan using native vegetation that improves the functional attributes of
the buffer. A buffer enhancement plan is being prepared as part of this project submittal so
that a buffer reduction can be approved by the Department of Community Development.
See attached sections of the Jefferson County Code.
A site plan has been developed to show the extent of wetlands and the maximum buffer
available with the potential building site shown as a hatched area along the south edge of the
property. The exact location of the home is not shown but it appears that it will be
constructed toward the west edge of the property where the widest area of upland is
Lingenbrink
March 14, 2007
Page 7
available. The site plan indicates that the widest buffer will be 30 feet between the
buildable area and the estuarine wetland. The buffer from the palustrine area of wetland
will also be 30 feet. A buffer enhancement plan has been prepared as a separate document
and describes in detail the justification for the buffer reduction, potential impacts of the
reduced buffer, and the fact that the enhanced buffer will function as good as or better than
the required buffer in its current condition.
In summary, a Category II estuarine and palustrine wetland associated with the Bridgehaven
Channel occupies the southern portions of this site located on North Beach Drive with the
required 100 foot buffer making up the remainder. The building site has been reduced to
an area immediately along the road and proposes reducing the buffer to 30 feet in order to
constructa single family home. There are no alternatives ,to the proposed building site as
this parcel is constrained by North Beach Road to the south, the road slope to the west, the
estuary to the north and additional homes to the east. A buffer enhancement plan is
proposed to improve buffer conditions and allow it to function better at a reduced width
than at the required width-.

JEFFERSON COUNTY SOIL SURVEY
DESCRIPTION OF SOIL TYPES
The soils described in this appendix are excerpts, considered applicable to urban
development, taken from the Soil Conservation Service, Soil Survey of Jefferson County
Area, Washington, August, 1975. For further information, see pages 13-14 of the soil
survey.
CfC Cassolary sandy loam. 0-15 % slopes. The Cassolary soil series consists of well-drained
soils on upland terraces that formed in reworked glacial and marine sediments. Native
vegetation is mainly Douglas fir, western red cedar, western hemlock, red alder, big leaf
maple, rhododendron, salal, huckleberry, and sword fern. Cassolary soils are associated
with Agnew, Alderwood, Clallam, Dick, Everett, Indianola, Kitsap and Tukey soils. The
Cassolary 0-15 % slopes is nearly level to rolling on upland terraces where the slopes are
mostly 5 to 10%. Included in this mapping are small areas of Kitsap soil types. This soil is
well drained and the permeability is moderately slow. Runoff is slow to medium and the
hazard of water erosion is slight to moderate. This soil is used mainly for production of
trees and for recreation areas and wildlife habitat. A small acreage is used for permanent
pasture, hay and home garden crops.
Lu Lummi silt loam. The Lummi series consists of poorly drained soil that formed in
stratified marine and alluvium in lowland areas adjacent to river estuaries and tidal salt
marshes slightly above sea level. Slopes range from 0-3 percent and native vegetation
consists mostly of salt tolerant reeds, sedges, and grasses and wild rose, Spiraea, and a few
scattered alder, willow, cottonwood, western hemlock, Douglas fir, and western red cedar.
Included with this soil in mapping are small areas of organic soils. This soil is poorly
drained and permeability is moderate. Runoff is very slow to ponded and the hazard of
water erosion is slight to non-existent except along stream channels. A seasonal water table
is at a depth of 1 to 2 feet. About half the acreage of this soil is cleared and used for
growing pasture, hay or silage. Small areas are used for growing home garden crops such as
berries, bulbs, and vegetables. The rest is used for brushy pasture and livestock grazing and
for wildlife habitat, recreation areas and rural homesites.
Td Tidal Marsh. Tidal marsh (Td) consists of nearly level, extremely wet, salty, or brackish
areas within the overflow limits of high tides. Soil materials in most places are deep deposits
of heterogeneous river alluvium that are continually saturated with salt water. No soil
formation has taken place. These mixed materials are gray or greenish gray and mottled.

18.15.340 Protection standards.
(I) General. Application for a project on a parcel of real property containing a designated wetland or its buffer shall
adhere to the requirements set forth below.
(2) Delineation. An applicant submitting a project application shall also submit, and have approved, a wetland
delineation report as specified in lCC 18.15.400. Additionally, the following provisions shall apply:
(a) The location of the wetland and its boundary shall be determined through the performance of a field
investigation utilizing the methodology contained in the Washington State Wetlands Identification and Delineation
Manual, March 1997, or as amended hereafter.
(b) If the wetland is located off of the property involved in the project application and is inaccessible, the best
available information shall be used to determine the wetland boundary and class.
(c) After approval of the delineation report, the wetland boundary shall be staked and flagged in the field.
(d) This requirement may be waived under the following circumstances:
(i) Single-Family Residences. The requirement for a wetland delineation and special report may be
waived for construction of a single-family residence on an existing lot of record if field investigation by
county staff indicates the following:
(A) Sufficient information exists for staff to estimate the boundaries of a wetland without a
delineation; and
(B) The single-family residence and all accessory structures and uses are not proposed to be
located within the distances identified in Table 3-3, below, from the estimated wetland boundary.
(ii) Subdivisions and Short Subdivisions. The requirement for a wetland delineation and special report
will be waived for subdivisions and short subdivisions of an existing lot of record if field investigation by
county staff indicates the following:
(A) Sufficient information exists for staff to estimate the boundaries of a wetland without a
delineation; and
(B) Building envelopes or building setback lines are not proposed to be located within the
distances identified in Table 3-3, below, from the estimated wetland boundary.

Notes:
1. These buffers are one part of the complete requirements necessary to qualify for a waiver. See subsection (2) of this
section.
2. These are not standard wetland buffers: they are optional buffers for cases when a delineation is not made. These
minimum waiver buffers, shown in Table 3-3, are 15 times the standard buffer widths identified in this article. If a single-
family residence, building envelope, or setback line in a subdivision is proposed to be closer to the wetland than the distance
identified in the table, a wetland delineation report must be performed.
3, The same opportunities for exemption from delineation shall apply to uncategorized wetlands. The department of
community development shall be responsible for determining the wetland category.
4. The following shall not be located within the distances identified in the table: (a) single-family residences and all
accessory structures and uses; (b) subdivision building envelopes and setback lines.
(3) Drainage and Erosion Control. An applicant submitting a project application shall also submit, and have approved, a

drainage and erosion control plan as specified in this chapter. The plan shall discuss, evaluate and recommend methods to
minimize sedimentation of designated wetlands during and after construction.
(4) Buffer Marking. Upon approval of the delineation report the location of the outer extent of the wetland buffer shall
be marked in the field as follows:
(a) A permanent physical separation along the upland boundary of the wetland buffer area shall be installed and
permanently maintained. Such separation may consist of logs, a tree or hedge row, or other prominent physical
marking approved by the administrator.
(b) Buffer perimeters shall be marked with temporary signs at an interval of one per parcel or every 100 feet,
whichever is less. Signs shall remain in place prior to and during approved construction activities. The signs shall
contain the following statement: "Wetland & Buffer - Do Not Remove or Alter Existing Native Vegetation."
(c) In the case of short plat, long plat, binding site plan, and site plan approvals under this code, the applicant
shall include on the face of any such instrument the boundary ofthe wetland and its buffer.
(d) The applicant may also choose to dedicate the buffer through a conservation easement or deed restriction
that shall be recorded with the Jefferson County auditor. Such easements or restrictions shall, however, use the
forms approved by the prosecuting attorney.
(5) Buffers - Standard Requirements. The following buffer provisions shall apply:
(a) Buffer areas shall be required to provide sufficient separation between the designated wetland and the
adjacent proposed project.
(b) The appropriate width of the wetland buffer shall be determined by either: application of the standard buffer
widths set forth below in Table 3-4; or by variations to the standard buffers as allowed in subsections (6), (7) and (8)
of this section.
(c) Buffers shall remain naturally vegetated except where the vegetation has been disturbed, invaded by highly
undesirable species (e.g., noxious weeds), or would substantially benefit from the increased diversity of introduced
species. Where buffer disturbance has occurred during construction, replanting with native vegetation shall be
required. Minor pruning of vegetation to enhance views and removal of undesirable species (e.g., alders) may be
permitted by the administrator on a case-by-case basis.
(d) All buffers shall be measured perpendicularly from the wetland boundary as surveyed in the field.
(e) Standard wetland buffer widths shall be as established in Table 3-4.
Table 3-4. Standard Buffer Widths for Wetlands
Wetland Category Standard Buffer Width
I 150 feet
II 100 feet
III 50 feet
IV 25 feet
(6) Reducing Buffer Widths. The administrator may reduce the standard wetland buffer widths, when the project
applicant demonstrates both ofthe following to the satisfaction of the administrator:
(a) Standard wetland buffer width averaging as set forth in this article is unfeasible.
(b) The project application includes a buffer enhancement plan using native vegetation which substantiates that
an enhancted buffer will improve the functional attributes of the buffer to provide additional protection for functions
and values.
(7) Increasing Buffer Widths. The administrator may increase the standard wetland buffer widths when a larger buffer is
necessary to protect wetland functions and values based on local conditions. This determination shall be made only when the
department demonstrates anyone of the following through appropriate documentation:
(a) A larger buffer is necessary to maintain viable populations of existing species.
(b) The wetland is used by species listed by the Washington State Department of Wildlife as endangered,
threatened, or sensitive, or has documented priority species or habitats or essential or outstanding potential habitat
for those species, or has unusual nesting or resting sites (e.g., heron rookeries and raptor nesting trees).
(c) The adjacent land is susceptible to severe landslide or erosion, and erosion control measures will not
effectively prevent adverse wetland impacts.
(d) The adjacent land has minimal vegetative cover or slopes greater than 45 percent.
(8) A veraging Buffer Widths. The administrator may modify the standard wetland buffer widths set forth in this section
by averaging. Buffer width averaging shall be allowed only when an individual or firm meeting the criteria of lCC I!', 1 ~ ,Jllf!
(2) demonstrates all of the following to the satisfaction of the administrator:
(a) Width averaging will not adversely impact the wetland functional values;
