INTRODUCTION
The delineated wetland discussed in this report is situated on the 4 lots of(Short Plat 3045)
on Lynch Road near Shelton, Mason County, Washington (Appendix A-1). This parcel is
located in the NE 1/a of the SE 1/a of Section 29, T 20 N, R 2 W WM. The 22 acre parcel has
been short platted into four — 5 acre parcels for the eventual construction of a single family
home on each newly created lot. These parcels are situated in a rurally developed area with
single family homes on large forested parcels off site to the north and south. Totten Inlet lies
to the east of the properties and Lynch Road lies along the west side. There is a well
maintained access road that enters from Lynch Road at the southwest comer of Lot 4 acre
parcel and continues east along the southern edge down to a single family home that lies on
the east end. The topography consists of a shelf on the west side of these properties along ,
Lynch Road. This shelf slopes down moderately to the east and flattens out and ends near
the east edge of the parcels. The topography changes into undulating terrain that slopes
down slightly to the south with a narrow ravine along the north line of Lot 1. There is a
single family home to the north and at least two to the south. Buffer averaging is proposed to
accommodate the driveway and the future building/drainfield site for Lot 1. No alteration of
buffer is proposed on any of the other four platted lots.
These parcels were logged in the past 20 years and they are now dominated by a young
mixed forest with moderate to dense shrub and herbaceous layers with some of the larger
trees left standing. The forest is Currently dominated by bigleaf maple and alder with areas of
mixed forest containing Oregon ash, fir, hemlock, cedar and cascara that has a dense shrub
layer dominated by salmonberry and blackberry with overgrown logging roads crisscrossing
the property. Two wetlands were identified and delineated for the original short plat of the
22 acre parcel. Wetland A is located on the eastern 2/3 these lots and consists of a seasonally
flooded, forested wetland with dense scrub/shrub and emergent components. This system
continues offsite for a short distance to the north and south. It appears to meet the criteria for
a Category III system, because of its moderate size and vegetative diversity, which gives it
both potential and opportunity for habitat functions. A 110 foot buffer is required from this
wetland because it scores 20 points for habitat functions. Wetland B is a forested sloping
wetland located in the northwest corner of Lot 1. It is a Category III wetland that has limited
potential and opportunity for habitat functions and only scores 18 points so a 60 foot buffer is
required.
The wetland boundary was delineated on August 8"' and 9`h 2003, May of 2008, and again in
July of 2010 using the Department of Ecology Washington State Wetlands Identification and
Delineation Manual (Publication#96-94). This manual requires the use of the three-
parameter wetland methodology (wetland hydrology, hydrophytic vegetation and hydric
soils) when making wetland determinations (see Appendix C for criteria used to make
wetland determinations). This site was logged over 18 years ago and has recovered well and
is under normal circumstances so the Routine On-Site Method was used to make the on-site
wetland boundary determination. This report has been prepared in accordance with the
1
Mason County Critical Areas Ordinance No. 138-06 (CAO) and includes a discussion of the
on-site wetlands with respect to the data collected in the field used in conjunction with
information obtained from the Mason County Soil Survey and National Wetlands Inventory.
It includes the wetland categorization, wetland classification and a functional values
assessment.
BACKGROUND INFORMATION
Mason County Soil Survey
The on-site soils are mapped as Ab Alderwood gravelly sandy loam 5-15% slopes on the
west edge, Bd Bellingham silt loam 0-3% slopes in a large pocket near the center of the south
line, Ib Indianola loamy sand 5-15% slopes throughout the center of the property and Rb
Rough broken land on the east edge of the property, according to the Soil Survey for the
Mason County area, September 1960. Alderwood, Indianola and rough broken soils are not
classified as hydric. Bellingham soils are classified as hydric and the delineation revealed
wetland conditions in the onsite portion of the mapped soil unit. See Appendix A-3 for this
parcel as located on the soil survey and Appendix B for description of the on-site soils.
National Wetlands Inventory
The US Fish and Wildlife Service, National Wetlands Inventory (NWI), Squaxin Island
Quadrangle does not map any onsite wetlands and maps the shoreline as Estuarine
Unconsolidated Shoreline Regularly Flooded. See Appendix A-4 for site located on the NWI
map.
Priority Species
There are no Washington State Priority 1, 2, or 3 plant or animal species known to exist on
the parcel (Washington Natural Heritage Program, 2007/2009 update) nor were any
identified during our field survey. The presence of priority species was determined using the
printed edition and a data base search was not completed at this time.
WETLAND ASSESSMENT
This section describes the delineated wetlands with respect to the three parameters as
collected in the field and recorded on wetland data forms. Two wetlands were identified and
delineated in the property. Wetland A is a forested system across the east half that continues
offsite to the north and south. The onsite portion is predominantly forested with a dense
underlying scrub/shrub and herbaceous layers. This system is located between low hilltops
on the east and west sides of the property and drains slowly to the south for an undetermined
distance. Wetland B is located at the northwest comer of Lot 1 and extends south almost to
the north property line of Lot 2 and turns north and extends offsite to the north. It is a
forested, sloping wetland that has moderate to dense underlying shrub and herbaceous layers.
It is reasonably disturbed and lacks a significant connection to other habitats and wildlife
corridors. This property was logged a number of years ago and appears to be recovering very
2
L
well with the exception of Scots broom and blackberry starting to invade along the perimeter
of the property. There are two driveways that cut through the wetland along the south
property line. One is onsite and the other is just offsite and serves the property to the south.
See Appendix A-2a for location of wetland boundary flags and wetland test holes. See
Appendix G for Wetland Data Forms 1, 4 5 and lb.
The following sections describe the data collected at test holes in the wetland and adjacent
upland and used to make the wetland boundary determination. The wetland data is described
in this section and each section includes a description of the dominant plant species, the soil
profile and whether hydric conditions are present, and the presence/absence of wetland
hydrology and/or wetland hydrology indicators. The dominant plant species identified by
common and botanical name along with the indicator status (OBL, FACW, FAC, etc. See
Appendix D for Definition of Indicator Status) are listed on the back of each data form. The
presence of hydric soil conditions is examined in 16 inch soil holes conducted at each test
hole. The hydric soil criteria is met when there is a low soil matrix chroma at 10 inches or
- just below the A horizon. The chromas are determined using damp soil samples that are
compared to a corresponding color chip in the Munsell Soil Color Charts. The chromas were
_ then recorded on the data sheet using Hue (YR) and Value/Chroma. Any Hue and Value
with a low Chroma is typical of hydric (wetland) soils that have developed over time due to
inundation or saturation by water. The presence or absence of wetland hydrology and/or
wetland hydrology indicators includes the source of hydrology and direction of flow (if
evident). Wetland Classification, Wetland Category and Required Buffers follow the
description of the wetland and upland data.
Soils
Wetland A: Test Holes 1, 4 and 5 are completed in Wetland A. Test Holes 1 and 4 revealed
1 a single layer soil profile that consists of a silt loam and has a matrix chroma of 10 YR 2/1
without mottling. Test Hole 5 revealed a two layer soil profile with a 12 inch thick surface
horizon consisting of a sandy loam that has a matrix chroma of 10 YR 3/1 without mottling.
The subsurface horizon extends to the bottom of the hole and consists of a slightly
compacted fine sandy loam that has a matrix chroma of 10 YR 5/2 without mottling.
Wetland B: Test Hole lb was completed near the center of the Wetland B to document
typical wetland conditions. The test hole revealed a single layer soil profile consisting of a
sandy silt loam that has a matrix chroma of 10 YR 2/1.
Hydrology
Wetland A: Hydrology was present during the field investigations as soil saturation to the
_ surface soil at each Wetland A test hole with evidence of surface hydrology indicated by
surface scouring, sediment stains, algal mats and debris deposits. The source of hydrology
for the wetlands appears to be seeps/springs along the west edge of the wetland as well as
surface water runoff from upland areas and direct rainfall. There may also be a seasonally
3
perched water table. Water flows seasonally to the south where it drains into a ditch along
the existing road through a culvert under the existing road and continues offsite to the south
for an undetermined distance.
Wetland B: Hydrology was present as soil saturation with water standing in the hole at a
depth of six inches from the surface. There is evidence of standing water in shallow
depressions throughout the onsite portion of this wetland system with depths up to 6 inches
during the winter months. This wetland is fed by seeps from the adjacent slopes as well as
runoff and direct rainfall. Flow of water is down the slope in a northerly direction where it
flows into a steep sided ravine that lays offsite to the north.
Vegetation
Wetland A: This is a large forested wetland system with a few large trees growing on
hummocks. The dominant species include Oregon ash (Fraxinus latifolia) FACW; red alder
(Alnus rubra) FAC; cascara (Frangula purshiana) FAC-; western hemlock (Tsuga
heterophylla) FACU and western red cedar (Thuja plicata) FAC with Douglas fir
(Pseudotsuga menziesii) FACU and bigleaf maple (Acer macrophyllum)FACU on
hummocks and along the perimeter. The shrub layer is dominated by salmonberry (Rubus
spectabilis) FAC; hardback (Spiraea douglasii),FACW; pacific crabapple (Malus fusca)
FACW- and Himalayan blackberry (Rubus armeniacus) FACU with lesser amounts of salal
(Gaultheria shallon) FACU and red elderberry (Sambucus racemosa) FACU growing on
hummocks in and along the wetland fringe. The herbaceous layer is dominated by slough
sedge (Carex obnupta) OBL; water parsley (Oenanthe sarmentosa) OBL; skunk cabbage
(Lysichiton americanum) OBL; lady fern (Athyrium filix femina) FAC and creeping
buttercup (Ranunculus repens) FACW with low percentages of cattail (Typha latifolia) OBL
and reed canary grass (Phalaris arundinacea) FACW.
Wetland B: This wetland is a forested system that has a moderate to dense underlying shrub
and herbaceous understory. It is dominated by red alder (A. rubra) FAC and western red
cedar (T. plicata) FAC with lower percentages cascara (F. purshiana) FAC- western hemlock
(T. heterophylla) FACU; Oregon ash (F. latifolia) FACW; Douglas fir (P. menziesii) FACU
and bigleaf maple (A. macrophyllum)FACU on hummocks and along the perimeter. The
shrub layer is dominated by salmonberry (R. spectabilis) FAC; hardback (S. douglasii)
FACW; and Himalayan blackberry (R. armeniacus) FACU with lower percentages of'salal
(G. shallon) FACU and red elderberry (S. racemosa) FACU growing on hummocks in and
along the wetland fringe. The herbaceous layer is dominated by slough sedge (C. obnupta)
OBL; water parsley (0. sarmentosa) OBL; skunk cabbage (L. americanum) OBL; lady fern
(A.filix femina) FAC and creeping buttercup (R. repens) FACW.
Wetland Classification
The wetlands have been classified according to the US Fish and Wildlife Service,
Classification of Wetlands and Deepwater Habitats of the United States, Cowardin et. Al.
December 1979 (1992 reprinted edition). This method of wetland classification represents a
4
i
hierarchical division of wetlands based on their specific attributes (system, class, hydrologic
regime). System describes a wetland's association with a body of water (estuarine,
Palustrine, Riverine, etc.), while the class refers to the dominant vegetative community
(aquatic bed, emergent, forested). Wetland A and B are classified as Palustrine Forested
Seasonally Flooded systems, which is abbreviated PFOC.
I
Wetland Category
The Mason County Critical Areas Ordinance (CAO) requires that identified and delineated
wetlands be categorized using the revised 2004 Washington State Wetlands Rating System
for Western Washington (Publication#04-06-025). This system utilizes hydrogeomorphic
characteristics to determine the potential and opportunity for a particular wetland to perform
water quality, hydrologic and habitat functions. It differentiates wetlands into four categories
ranging from Category I systems that typically have high potential and opportunity to
perform these functions to Category IV systems that have low potential and opportunity to
perform the functions. A rating form that asks a series of questions is used to identify the
wetland's position in the landscape (sloping, depressional, riverine, etc.) and specific
characteristics that would indicate that it has potential to perform the water quality,
hydrologic and habitat functions. When the wetland has opportunity to perform the
functions, it receives a multiplier of 2. The scores are then added up and a category is
assigned based on the number of points received as follows: Category I wetlands score 70
points or greater, Category II systems score between 51-69 points, Category III systems score
30-50 points and Category IV wetlands score less than 30 points.
Wetland A: The rating form reveals that this wetland meets the criteria for a Category III
system because it scores a total of 42 points. The wetland has low potential/opportunity to
perform water quality functions because of its position on sloping terrain so it scores 6 points
for this function. It scores 16 points for hydrologic functions because it has both potential
and opportunity to perform hydrologic functions. For habitat functions, the wetland scores
20 points because of its large size, diversity in the forested community and close proximity to
priority habitat areas. See Appendix E-la for Wetland A Rating form.
Wetland B: The wetland rating form reveals that Wetland B meets the criteria for a
Category III system because it scores a total of 32 points. The wetland has low potential and
opportunity to perform water quality functions so scores only 8 points. For hydrologic
functions, this wetland scores 3 points for potential because of its position on a slope but
receives the multiplier because it has opportunity to perform this function so it scores a total
of 6 points. For habitat functions, this wetland scores 18 points because it has low potential
but high opportunity to provide habitat for local wildlife species. See Appendix E-lb for
Wetland B Rating Form.

Required Buffers
The Mason County Critical Areas Ordinance (CAO)requires varying buffer widths that are
based on the point total on the wetland rating system(category), the total score for habitat
functions and the intensity of the proposed land use. The newly created lots represent
moderate intensity land uses because a single home is proposed on lots larger than 1 acre so
moderate intensity buffers are required for these delineated wetlands. Wetland A is a
Category III system that scores 20 points for habitat functions on the rating form so a buffer
of 110 feet is required from this wetland. Wetland B is also a Category III system but it
4 scores only 18 points for habitat so a buffer of 60 feet is required. The buffers are measured
horizontally from the delineated boundaries and 15 foot building setbacks are required
between the edge of the buffer and the future home on Lot 1. Buffer reductions are possible
through the averaging process wherein buffers are reduced in one location and increased in
another so that the buffer is an average width of 60 or 110 feet for the onsite wetlands.
Averaging is proposed for the driveway access and to accommodate the building site on Lot
1. Reductions are proposed along the southern buffer edge of Wetland B and along the
northern buffer of Wetland A where it extends onto Lot 1. See Appendix E-2 for required
buffer and buffer averaging criteria of the Mason County CAO.
Off-Site Wetland Description
Wetland A extends offsite to the north and south for an undetermined distance. The offsite
portions of this system does not appear to make any significant turns that would cause the
buffers to extend onto this property. Wetland B extends offsite to the north for an
undetermined distance and since it is on private property it could not be fully examined to
determine the extent of wetlands. There do not appear to be any offsite areas of Wetland B
lying closer than 60 feet from the north property line so no additional buffers will extend
onto this property.
UPLAND DESCRIPTION
The upland area lies on a shelf along the west edge of the property that slopes down to the
east with a low ridge crossing the northeast comer. The original 22 acre parcel was logged
within the past 20 years and the lots are dominated by coniferous and deciduous trees with a
narrow coniferous zone along the east edge of the parcel. Several of the larger trees were-left
standing and there are many downed logs and stumps in and along the upland/wetland fringe.
The main access road enters the parcel at the southwest comer of Lot 4 and extends east
along the south property line onto the eastern 5 acre parcel (not part of this short plat). There
is a second access road near the northeast comer and extends east and turns into a series of
old skid roads that crisscross the parcel. See Appendix G for upland test holes 2, 3, 6-12 and
2b. See Appendix A-2 for location of upland features and test holes.
6
Vegetation
The upland areas around the delineated wetlands are dominated by red alder (A. rubra) FAC;
cascara (F. purshiana) FAC-; western hemlock (T. heterophylla) FACU; bigleaf maple (A.
macrophyllum) FACU and bitter cherry (Prunus emarginata) FACU with lower percentages
of western red cedar (T.plicata) FAC; Douglas fir (P. menziesii) FACU; pacific madrone
(Arbutus menziesii) UPL and Scouler's willow (S. scouleriana) FAC intermixed. The shrub
layer is dominated by salmonberry (R. spectabilis) FAC; Himalayan blackberry (R.
armeniacus) FACU; red elderberry (S. racemosa) FACU; salal (G. shallon) FACU; Indian
plum (Oemlaria cerasiformes) FACU and hazelnut (Corylus cornuta) FACU with lesser
am6unts of Oregon grape (Berberis nervosa) UPL; Scots broom (Cytisus scoparius) FACU
and ocean spray (Holodiscus discolor) UPL. The herbaceous layer is dominated by sword
fern (P. munitum) FACU and trailing blackberry (R. ursinus) FACU with moderate to dense
patches of deer fern (Blechnum spicant) FAC+; false lily of the valley (Maianthemum
dilatatum) FAC; Dewey sedge (Carex deweyana) FACU and bleeding heart (Dicentra
formosa) FACU.
Soils and Hydrology
The soil test holes completed in the upland areas revealed the presence of non-hydric soil
conditions. In general, the soils are gravelly sandy loam in texture and consist of a variety of
soil profiles from the past logging activities. Test Holes 9-12 revealed a single layer soil
profile to-16 inches deep consisting of a gravelly sandy loam that have matrix chromas
ranging from 10 YR 3/3 to 10 YR 5/3 with mottling at Test Holes 11 and 12. Test Holes 2,
2b, 3 and 6-8 revealed two layer soil profiles consisting of a 3 to 12 inch thick sandy loam
surface horizons having matrix chromas of 10 YR 3/2 to 10 YR 3/3 without mottling. The
subsurface horizons consist of gravelly sandy loam with matrix chromas ranging from 10 YR
4/3 to 10 YR 5/2 without mottling.
Hydrologic indicators were present in Test Holes 6-9 as surface scouring and sediment
- stained vegetation as a result from old logging roads carrying excess surface water during the
rainy season. These hydrologic indicators are presumed to be a result of seasonal rains that
are not able to drain through the soils due to the historic logging disturbances. No evidence
of prolonged wetland hydrology during the growing season was found in any of the upland
areas. Each of the upland Test Holes 2, 2b, 3, and 6-12, were placed in marginal and typical
upland areas to determine whether wetland parameters are present. These areas were
determined to be non-wetland because they lack positive indicators for each of the three
wetland parameters.
FUNCTIONAL VALUES ASSESMENT FOR THE DELINEATED WETLANDS
Flood control, groundwater recharge/discharge, water quality maintenance, biological
support, and many other functions are performed by wetlands. The table below lists the most
common values and functions of wetlands and provides a value rating for each function and
the rationale used to make the rating determination.
7
Value or Function Rating and Rationale
Storm and Flood Water MODERATE
Storage Wetlands A and B are situated on wide sloping terrain and
there are many small pockets that give both wetlands the
potential to store excess water. Because these wetlands are
low in the watershed, they have limited opportunity to
minimize flooding impacts for downstream areas.
Water Quality Protection MODERATE
Wetlands A and B receive runoff from the adjacent uplands
and because they contain a thick cover of shrub and
emergent plants, they have the opportunity to filter
pollutants from the water. Since the wetlands are situated
along a wide slope with small depressional pockets they also
facilitate settling of some sediment.
Groundwater Discharge MODERATE-HIGH
These wetlands have seep/spring activity occurring along the
west edges providing year round hydrology to both systems.
Groundwater Recharge MODERATE
Because there is a ditch on the south edge of Wetland A, it
appears that much of its water drains via the ditch so there is
minimal potential for this wetland to recharge groundwater
supplies.
Wetland B receives most of its hydrology from seeps and
springs along the western wetland edge that drains
northwesterly eventually into the seasonal stream offsite to
the northeast so there is minimal potential or opportunity to
recharge groundwater.
Biological Support HIGH
Although both wetlands are predominantly forested systems,
there is high diversity within the three layers of each forest
that provides a wide variety of habitats. Both wetlands
provide localized habitat areas for a number of small bird
and mammal species and provide characteristics important to
a wider variety of wildlife species such as seasonally flooded
areas and vertical snags. Wetland A is in closer proximity to
the marine waters of Totten Inlet so has slightly higher
values for biological support and habitat functions.
Aesthetic Values MODERATE
Educational Values Wetlands A and B are a moderate to large diverse wetlands
Recreational Values with moderate buffers that would be valuable to adjacent
and future property owners and would provide opportunities
for bird watching, hiking, and photography.

PROJECT DESCRIPTION AND POTENTIAL IMPACTS
A short plat was approved for the 22 acre parcel and 4 building lots that range in size from
4.99 acres (Lot 1) to 8.3 acres (Lot 2) were created. All four lot will have direct access from
Lynch Road since the building sites are all situated at the west end. The building sites on
Lots 2-4 will be situated well outside the required buffer from the wetlands so will have
minimal impact on them. Lot 1 is constrained by wetland and buffer from both Wetlands A
I and B and the buffer of Wetland B constrains access to the building site. The access to Lot 1
will be along the property line shared by it and Lot 2 and because the buffer from Wetland B
extends across the line, a reduction is necessary to accommodate the future driveway.
I Reduction is also proposed from Wetland A where its buffer extends onto Lot 1 to
accommodate the future building and drainfield areas. Buffer reductions are not proposed on
any of the other short platted lots because they are not constrained by wetland and buffers as
I Lot 1.
Because each of the lots is at least 5 acres in size and three of the lots will maintain the
required wetland buffers, the impacts to the wetlands on this property will be minimal.
Typical impacts are a result of creation of impervious surface on developed properties that
Iaffect the storage capacity of the wetland, the water quality protection function and discharge
of groundwater. The buffer will be retained in its current forested condition so it will
function to remove pollutants and sediments from water generated on impervious surfaces.
IThere should be minimal impact to the water quality protection function of this wetland as a
result and the storage capacity will probably not be exceeded since water will likely soak into
the permeable upland soils within the buffer. The groundwater discharge function could be
impacted by the creation of impervious surface on upland outside the buffer because water
will no longer be able to percolate into the soils and flow down slope where it can discharge
Iinto the wetland areas. The buffer width of 110 feet from Wetland A will be sufficient to
provide percolation and discharge into the wetland. The lots are each situated along Lynch
Road so have direct access to the building sites and will not necessitate creation of driveways
across the wetlands that could further fragment the corridor and habitat conditions. The
buffer will function to screen noise and light impacts from the wetland and minimize the
' impacts of future homesite development on wildlife use within the wetland. In general, the
project will have minimal adverse impact on wildlife usage within the wetland because the
new homes will not fragment the habitat or corridor.
Buffer Averaging Plan
Buffer averaging is proposed on Lot 1 to allow construction of the driveway access from
Lynch Road and to accommodate the building and drainfield areas in the middle section
because it is severely constrained by the two wetlands. Reductions are proposed along both
wetlands with increases proposed adjacent to Wetland B. Wetland buffer width averaging is
allowed in the Mason County Critical Areas Ordinance (Section 7.01.068E.2.c. Wetland
Buffer Width Averaging) but are subject to the following conditions:
9
a. The total area contained in the buffer after averaging shall be no less than that
contained within the buffer prior to averaging. In other words, the mitigation for
buffer impacts will be on a minimum of a 1:1 ratio; and
b. Buffer averaging will incorporate site conditions to provide measures to increase the
functions and values of the wetland buffer beyond what is currently in place; and
C. In no instance shall the buffer width be reduced to less than 75% of the required with
for each of the wetland categories.
The buffer reductions on Lot 1 are proposed in two locations (see Appendix A-2b for buffer
averaging plan). The first is along the easement that lies on the line between Lots 1 and 2 to
permit construction of the driveway within the easement where it lies at the outer edge of the
buffer. This reduction is proposed along Wetland B, which lies at the west end of Lot 1, and
is the minimum necessary to accommodate the driveway to the building site. The required
buffer from Wetland B is 60 feet and the reduction proposes a minimum buffer of 45 feet,
which meets the criteria requiring no less than a 75%reduction. The total area of buffer
reduction is 1,867 square feet in this location. The second buffer reduction is for the buffer
from Wetland A where it crosses onto Lot 1. The required buffer from Wetland A is 110 feet
and the reduction proposes a minimum buffer of 82.5 feet. The total area of buffer reduction
is 7,023 square feet in this location. Buffer increase is proposed on the east side of Wetland
B so that there is increased buffer for this wetland on Lot 1. The total area of buffer increase
is 8,890 square feet as it incorporates both proposed reduction areas. The increased buffer
provides exactly 1:1 compensation for the reduced buffer based on the overall square
footage.
The proposed buffer averaging meets Mason County Critical Areas Ordinance Wetland
Buffer Width Averaging Criteria A and C automatically with the exact exchange of buffer
increase.for the buffer reduction and maintaining the final buffer width at 75% of the
required buffer. The reduction of the buffers are necessary to accommodate the features of
Lot 1 since it is more constrained by wetland and buffers than the other lots of this short plat.
The reduction proposed from Wetland A, which lies mostly on Lots 2, 3 and 4 but extends
across the southeastern portion of Lot 1, will not negatively impact the wetland because it
comes to a point in this location and this area has lower function than the remainder of the
wetland. Even though no additional buffer is proposed from Wetland A as part of the,
averaging plan, there will be no loss of buffer function because there is additional buffer
afforded to this wetland adjacent to the reduction area due to the position of the wetland on
Lot 2 (see Appendix A-2b for buffer averaging plan). Overall, there will be no significant
impact to the function of the buffer or wetland as a result of the reduction on Lot 1. The
reduction of buffer along the south end of Wetland B also will not negatively impact the
wetland function because there will be at least 45 feet of f0rested remaining between the
future driveway and the wetland boundary. The increased buffer adjacent to Wetland B will
provide additional protection for this wetland by creating a straight buffer rather than the
severely curving one that results when the 60 foot buffer is measured from the wetland
boundary. Since we humans work better with straight lines, the buffer can be easily
10
identified and marked so that intrusion is less likely than if the buffer remained in its current
configuration. This increased buffer also provides good protection for the offsite portions of
the wetland system.
While buffer reductions are proposed and essentially there will be less buffer in some areas
than in others, there will be no significant adverse impact to the wetland as a result of the
reductions. Impacts to wetlands as a result of lower buffers can occur however, on this
property, the buffer is being averaged with at least 75% of the width maintained in the
reduced areas and averaging is proposed to maintain 100% of the buffer on Lot 1. Because
the buffer is being averaged and the total buffer area is being maintained, the impacts to the
wetlands in the proposed reduction areas will be minimal if not non-existent. The forested
vegetation in the reduced buffer areas will be sufficient to provide noise and light protection
from the future building site and will provide areas where excess water can percolate into
upland soils for eventual discharge into the wetland. There will also be more than enough
area and vegetation to maintain the quality of water that happens to flow across the buffers
from the developed areas.
SUMMARY
The delineated wetlands discussed in this report are situated on the four lots of Short Plat No.
3045 on Lynch Road near Shelton, Mason County, Washington. Totten Inlet lies to the east
of the lots and Lynch Road lies to the west. There is an existing well maintained access road
that enters from Lynch Road at the southwest comer of the short plat and continues east
along the southern property line to a 5 acre parcel on the east side. The topography consists
of a shelf on the west side of the property along Lynch Road. This shelf slopes down
moderately to the north and east and flattens out just before the east edge of the platted lots.
A shallow ravine is located between the north line and the single family home further north
with a new single family home near the southeast corner and another further to the south.
The original 22 acre parcel was logged within the past 20 years and is now dominated by a
young mixed forest with moderate to dense shrub and herbaceous layers. The east edge is
dominated by alder and cascara while the vegetation on the remaining property is dominated
by a mixed forest of fir, hemlock, cedar and bigleaf maple with a dense shrub layer
dominated by salmonberry and blackberry with small overgrown logging roads crisscrossing
the property.
Two wetlands were identified on this parcel and are delineated as Wetland A and Wetland B.
They are moderate to large size seasonally flooded forested sloping wetlands each with a
moderate to dense shrub and emergent understory that extends a short distance offsite to the
north and south. Wetland A meets the criteria for a Category III system scoring 42 points on
the attached rating form and rates moderate to high for functional values. The project
proposes to maintain all of the 110 foot required buffers except on Lot 1 and the future
homes will have minimal impact on the functions of Wetland A despite reduction of the
buffer in one location. Wetland B also meets the criteria for a Category III wetland that rates
11
moderate to moderate-high for functional values. It scores,less than 20 habitat points on the
rating form so a 60 foot buffer is required. Buffer averaging is proposed to permit access to
Lot 1 as the buffer from Wetland B extends over the property line shared by Lots 1 and 2.
The reduction will be compensated in another location on Lot 1 so that the buffer of Wetland
B is an average width of 60 feet. The averaging plan also includes reduction of the 110,foot
buffer of Wetland A where it crosses onto Lot 1. The averaging plan appears to meet all of
the criteria of the Mason County Critical Areas Ordinance since there is an equal exchange of
buffer with a total of 8,890 square feet of buffer reduction in two locations and a total of
8,890 square feet of increase in the southeast buffer of Wetland B. There will be no
significant adverse impacts to either wetland as a result of the minor buffer reductions
because there is high quality forested buffer remaining in the reduced areas.
LIMITATIONS
This report has been prepared for the Bill Stinchfield family., It is important to acknowledge
that definition of plant community boundaries is not an exact science. Different agencies and
individuals may often disagree on exact boundaries and/or plant community classifications.
It is the responsibility of the various resource agencies that regulate development activities in
wetlands to make the final determination of wetland boundaries. Therefore, the information
presented in this report should be reviewed by the appropriate regulatory agencies prior to
detailed site planning and/or construction activities.

APPENDIX B
MASON COUNTY SOIL SURVEY
DESCRIPTION OF SOIL TYPES
The soils described in this appendix are excerpts, considered applicable to urban development,
rP Pp taken
from the Soil Conservation Service, Soil Survey of Mason County Area, Washington, September,
1960. For further information, see page 16 of the soil survey. Information listed below for
Alderwood soils was collected between 1951 and 1960 and uses for the individual soils have
probably changed since that time.
ALDERWOOD SERIES
The Alderwood series consists of brown, well drained, upland soils. They have developed from
mixed gravelly glacial till dominated by acid igneous rock. The imbedded gravel is mainly granite
and quartzite. Rainfall is 45 to 60 inches a year. The native vegetation is a dense forest consisting
almost entirely of Douglas fir and a dense understory of salal, Oregon grape, vine maple, and
huckleberry. Northeast of the Hood Canal the understory is mainly rhododendron. Alderwood soils
occupy the extensive rolling glacial moraines, and they are the dominant soils of the eastern part of
the county. The Alderwood soils are associated with the somewhat excessively drained Everett and
Indianola soils and with the moderately well drained Kitsap soils. Shelton and Hoodsport soils differ
from the Alderwood soils in that they have developed under high rainfall and from glacial till having
a much higher content of the basic igneous rock. The Shelton and Hoodsport soils are more reddish
throughout the profile. The Shelton soils are usually deeper to the cemented till than the Alderwood
soils.
Ab-Alderwood gravelly sandy loam 5-15% slopes This is the most extensive soil of the Alderwood
series. It occupies undulating to rolling moraines. In undisturbed areas, a 1 to 2 inch mat of very
dark brown, acid organic matter is on the surface. This grades to a thin, dark grayish-brown, highly
organic mineral soil. The surface soil consists of a friable, brown medium acid gravelly sandy loam
8 to 13 inches deep. Below the surface soil, to depths ranging from 18 to 24 inches, is a pale-brown
gravelly sandy loam that is very friable. Between this layer and the cemented till, is a 3 to 10 inch
layer of very pale brown gravelly sandy loam. The cemented till consists of light gray, gravelly
.� sandy loam, and it normally occurs at depths ranging from 24 to 32 inches. It is impermeable to
roots and very slowly permeable to water. The cemented substratum tends to restrict the rapid
downward movement of moisture. Not more than about 5 percent of this soil has been cleared and
is used for crops or pasture. Most of the cultivated acreage is near the inlets of Puget Sound in the
vicinities of Arcadia and Allyn. In this area, the Alderwood soils are associated with the better
agricultural soils of the Cloquallum, Sinclair, and Kitsap series. Hay, small grains, pasture, fruits,
nuts, grapes, and berries are the principal crops grown on the Alderwood soils. Nearly all the
uncleared acreage is in second-growth forest 70 to 80 years of age. Shallowness of the compact till
often inhibits growth of older trees. This soil is in capability subclass VIs and in site classes 4 and 5
for Douglas fir. Small areas along the border, where the soil is more than 32 inches deep to
compact till, are in site classes 3 and 4 for Douglas fir.

MASON CO UTNY 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 Mason County
Area, Washington; September, 1960. For further information, see page 18 & 38 of the
Soil Survey.
Bd Bellingham silt loam. This soil is widely distributed over the eastern part of the
-- county and is associated with the Cloquallum soils. On the Islands of Case Inlet and
Pickering Passage and bordering mainland, it is associated with the Kitsap soils.
Permeability of this Bellingham soil is slow. The available water capacity is high.
This soil is ponded during winter. Runoff is ponded, and water erosion is not a hazard
or is a slight hazard. This soil is used mainly for hay, pasture, woodland, and wildlife
T, habitat. Most of the area if artificially drained. When ponded, this soil serves as a
resting area for ducks, herons, and other waterfowl. Plantings of smartweed, wild
millet, and bulrush increase waterfowl populations. A high water table is above or at
w the surface throughout the rainy season. This soil if poorly suited to urban
development because of depth to the seasonal high water table, seasonal ponding, and
the shrink-swell potential of the subsoil. Septic tank drainage fields do not function
properly during the wet season because of the seasonal high water table and restricted
permeability.
Rb Rough Broken The soil, where it has been formed, is shallow, gravely and
variable, but has some characteristics of the dominant upland soils in the vicinity. The
_- vegetation is variable and its composition depends on aspect, seepage and depth of soil.
This mapping unit has no agricultural value and should be left in its natural cover to
prevent erosion. It is in capability subclass VIIe.

APPENDIX B
MASON 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 Mason County Area, Washington, September,
1960. For further information, see pages 29-30 of the soil survey. Information listed below for
Everett soils was collected between 1951 and 1960 and uses for the individual soils have probably
changed since that time.
MLANOLA SERIES
The soils in the Indianola series are excessively drained, droughty, brown soils of the uplands. They
have developed
p in hummocky and rolling ridges from glacial drift that consisted of loose, porous
sand. The sand came mainly from acid igneous rocks. The annual rainfall ranges from 50 to 70
inches and the native vegetation is mainly Douglas fir. Indianola soils occur in the eastern half of
the county in association with the Alderwood and Everett soils. They are unlike the Everett soils in
that they are not gravelly. They differ from the Alderwood soils in not being gravelly and in having
a sandy rather than a cemented substratum. Indianola soils are more nearly like the Lystair soils in
the western part of the county. They differ from those soils mainly in having brown and yellowish-
brown colors and less basic igneous material in the parent drift. The Lystair soils are brown and
reddish yellow, and they occur in an area of higher rainfall.
Ib Indianola loamy sand 5-15% slopes Stronger relief distinguishes this soil from Indianola sandy
loam, 0-5% slopes. Use and management are similar to those of the Indianola loam sand, 5-15%
slopes. Crop yields are somewhat higher because the surface soil has a slightly finer texture. The
supply of available moisture is slightly greater, but it is still low. This soil is in capability subclass
IVs and in site classes 3 and 4 for Douglas fir.
Id Indianola sandy loam 0-5% slopes The surface soil is very friable, weakly granular, brown
sandy loam. The depth to sand is slightly greater than the Indianola loamy sandy, 5-15% slope, but
the rest of the profile is similar. This soil has about the same uses and needs the same management
of Indianola loamy sand, 5-15% slopes. Because of the slightly finer texture of the surface soil and
greater depth to the sandy substratum, the supply of moisture is slightly higher; consequently, crop
yields are generally higher. This soil is in capability subclass IVs and in site classes 3 and 4 for
Douglas fir.
APPENDIX C: WETLAND DETERMINATION/DELINEATION METHODOLOGY
The definition for wetland established by the U.S. Army Corps of Engineers (COE) was used to
determine the presence and extent of wetlands on this parcel. Section 404 of the Clean Water Act
(1972) states that wetlands are:
"Those areas that are inundated or saturated by surface or groundwater
at a frequency and duration sufficient to support, a prevalence of vegetation
typically adapted for life in saturated soil conditions. Wetlands generally include
swamps, marshes,bogs, and similar areas."
This criteria is based on the Department of Ecology Washington State Wetland Identification and
Delineation Manual, the 1987 Corps of Engineers (COE) Wetland Delineation Manual and the 1989
Federal Interagency Committee for Wetland Delineation(FICWD). This committee included
representatives from the COE, U.S. Fish and Wildlife Service, Environmental Protection Agency, and
Soil Conservation Service, to establish technical procedures and guidelines for wetland determination
and delineation. These guidelines as set forth in both delineation manuals requires that three technical
criterion: (1)hydrophytic vegetation, (2) hydric soils, and (3) wetland hydrology must all be met for an
area to be identified as wetland. A general summary of these criterion or parameters as defined within
the COE and FICWD manuals include:
Hydronhvtic Vegetation Criterion: This criterion is
met when, under normal circumstances 50 percent or more
of the composition of the dominant species from
all strata are obligate wetland (OBL), facultative
wetland (FACW), and/or facultative (FAC).
Hydric Soil Criterion- This criterion is met for any
area having soils that are saturated, flooded, or
ponded long enough during the growing season to
develop anaerobic conditions in the upper part (USDA
Soil Conservation Service, 1987).
Wetland Hydrology Criterion: This criterion is met for
any area having permanent or periodic inundation, or
soil saturation to the surface, at least seasonally.
These three criterion are the basis for all field work and wetland delineation performed on this
p parcel.
The specific methodology used is outlined in the next section.
WETLAND DELINEATION METHODOLOGY
The wetland delineation followed the Routine On-site and Intermediate Determination Methods as
outlined in each manual. A summary of this method includes:
Plant Community Assessment. The entire project site was initially walked to identify the plant
community types present. This provided a rough picture of the type and extent of wetland(s)
which exist on site. Also observed and noted were topographical features,
1
hydrologic flow patterns, and any significantly disturbed areas. It was then determined wheth,
normal environmental conditions were present, or human modifications had occurred to the
wetland.
Selection of Sample Area(s). A series of sample areas or points were selected and flagged to,
best characterize the plant communities of suspected wetland and non-wetland areas. The
approximate location of these flagged sample points were noted on a map of the project site fo
subsequent survey.
Characterization of Plant Communities. At each sample point the dominant plant species
within the tree, shrub, and herb stratum were identified and noted on a data form. Species we`
identified and noted according to Flora of the Pacific Northwest(Hitchcock& Cronquist, 1973
The estimated percent areal cover and the indicator status (as listed in the National List of Plad
Species that Occur in Wetlands: 1988,Washington)were also noted on the data form. It was;.
then determined whether the hydrophytic vegetation criteria was met. When 50% or more of
dominant species have an indicator status of OBL, FACW, or FAC, the vegetation is consider'
hydrophytic.
Characterization of Soils. At each sample point, a hole 16 to 18 inches in depth was dug us'
a spade(an existing soil perk hole was used if available). Soil characteristics (matrix color,
mottles, etc.) were examined and noted. It was then determined whether the hydric soil criteri
was met. Hydric soil criterion is outlined on page 6 of the FICWD manual and pages 26 to 34
the COE manual.
Determination of Hydrology Criterion. At each sample point the presence of inundation
by water, soil saturation by water, or other hydrologic field indicators was noted. It was then
determined whether the wetland hydrology criterion was met.
Wetland Determination. The completed data forms were then examined for each selected
sample point within the plant communities. Each plant community meeting the hydrophytic
vegetation, hydric soil, and wetland hydrology criteria was considered.wetland. Data forms
numbered correspondingly to the sample points located on the final survey drawing.
DETERMINATION OF WETLAND-NONWETLAND BOUNDARY
After completing the determination method summarized above, the actual boundary between wetland
and non-wetland was delineated. This delineation was completed by:
1. recognizing obvious wetland and non-wetland areas,
2. identification of transitional areas between the two areas,
3. final determination of the boundary by further sampling of vegetation, soils, and hydrology.
The wetland Boundary was then flagged with numbered orange flags with WB (Wetland Boundary)
s then noted on a map, if available, for
flags was P
written on them. The approxi
mate location of these g
subsequent survey.
* Important Note: The exact location of the boundary between wetland and non-wetland areas may b>
difficult to determine, especially if transition areas are more gradual. In cases such as this the wetlan.
boundary is determined, after further sampling, by using the best possible professional judgment.

Which of the following priority habitats are within 330ft(100m)of the wetland unit?NOTE: the
connections do not have to be relatively undisturbed.
These are DFW definitions. Check with your local DFW biologist if there are any questions.
Riparian: The area adjacent to aquatic systems with flowing water that contains elements of
both aquatic and terrestrial ecosystems which mutually influence each other.
Aspen Stands: Pure or mixed stands of aspen greater than 0.8 ha(2 acres).
Cliffs: Greater than 7.6 in(25 ft)high and occurring below 5000 ft.
Old-growth forests: (Old-growth west of Cascade crest) Stands of at least 2 tree species,
forming a multi-layered canopy with occasional small openings;with at least 20 trees/ha(8
trees/acre)> 81 cm(32 in)dbh or>200 years of age.
Mature forests: Stands with average diameters exceeding 53 cm(21 in)dbh; crown cover
may be less that 100%;crown cover may be less that 100%; decay,decadence,numbers of
snags,and quantity of large downed material is generally less than that found in old-
growth; 80-200 years old west of the Cascade crest.
Prairies: Relatively undisturbed areas(as indicated by dominance of native plants)where
grasses and/or forbs form the natural climax plant community.
Talus: Homogenous areas of rock rubble ranging in average size 0.15 -2.0 in(0.5 -6.5 ft),
composed of basalt,andesite,and/or sedimentary rock, including riprap slides and mine
tailings. May be associated with cliffs.
Caves: A naturally occurring cavity,recess,void,or system of interconnected passages
Oregon white Oak: Woodlands Stands of pure oak or oak/conifer associations where
canopy coverage of the oak component of the stand is 25%.
Urban Natural Open Space:A priority species resides within or is adjacent to the open
space and uses it for breeding and/or regular feeding; and/or the open space functions as a
corridor connecting other priority habitats, especially those that would otherwise be
isolated;and/or the open space is an isolated remnant of natural habitat larger than 4 ha(10
acres)and is surrounded by urban development.
Estuary/Estuary-like:Deepwater tidal habitats and adjacent tidal wetlands,usually semi-
enclosed by land but with open,partly obstructed or sporadic access to the open ocean, and
in which ocean water is at least occasionally diluted by freshwater runoff from the land.
The salinity may be periodically increased above that of the open ocean by evaporation.
Along some low-energy coastlines there is appreciable dilution of sea water.Estuarine
habitat extends upstream and landward to where ocean-derived salts measure less than
0.5ppt. during the period of average annual low flow. Includes both estuaries and lagoons.
KMarine/Estuarine Shorelines: Shorelines include the intertidal and subtidal zones of
beaches,and may also include the backshore and adjacent components of the terrestrial
landscape(e:g.,cliffs,snags,mature trees, dunes,meadows)that are important to shoreline
associated fish and wildlife and that contribute to shoreline function(e.g.,sand/rock/log
recruitment,nutrient contribution,erosion control).

cultivation,grazing,and has less than 10% cover of non-native plant
species. If the non-native Spartina spp. are the only species that cover
more than 10%of the wetland, then the wetland should be given a dual Dual
rating(UII). The area of Spartina would be rated a Category II while the rating
relatively undisturbed upper marsh with native species would be a
Category I. Do not,however, exclude the area of Spartina in JAI -
determining the size threshold of 1 acre.
—At least 3/4 of the landward edge of the wetland has a 100 ft buffer of
shrub, forest, or un-grazed or un-mowed grassland.

Does the wetland unit(or any part of the unit)meet both the criteria for soils and
vegetation in bogs? Use the key below to identify if the wetland is a bog. Ifyou
answer yes you will still need to rate the wetland based on its functions.
1. Does the unit have organic soil horizons(i.e. layers of organic soil), either
peats or mucks,that compose 16 inches or more of the first 32 inches of the
soil profile? (See Appendix B for a field key to identify organic soils)?Yes-
go to Q. 3 No -go to Q. 2
2. Does the unit have organic soils, either peats or mucks that are less than 16
inches deep over bedrock, or an impermeable hardpan such as clay or
volcanic ash, or that are floating on a lake or pond?
Yes -go to Q. 3 No - Is not a bog for purpose of rating
3. Does the unit have more than 70% cover of mosses at ground level,AND
other plants, if present, consist of the"bog"species listed in Table 3 as a
significant component of the vegetation (more than 36% of the total shrub
and herbaceous cover consists of species in Table 3)?
Yes—Is a bog for purpose of rating No - go to Q.4
NOTE: If you are uncertain about the extent of mosses in the understory
you may substitute that criterion by measuring the pH of the water that
seeps into a hole dug at least 16"deep. If the pH is less than 5.0 and the
"bog"plant species in Table 3 are present, the wetland is a bog.
1. Is the unit forested(> 30% cover)with sitka spruce, subalpine fir,western
red cedar, western hemlock, lodgepole pine, quaking aspen, Englemann's

SC 4.0 Forested Wetlands (seep. 90)
Does the wetland unit have at least 1 acre of forest that meet one of these criteria for
the Department of Fish and Wildlife's forests as priority habitats? If you answer yes
you will still need to rate the wetland based on its functions:
— Old-growth forests: (west of Cascade crest) Stands of at least two tree species,
forming a multi-layered canopy with occasional small openings; with at least 8
trees/acre (20 trees/hectare)that are at least 200 years of age OR have a
diameter at breast height(dbh)of 32 inches (81 cm)or more.
NOTE: The criterion for dbh is based on measurements for upland forests.
Two-hundred year old trees in wetlands will often have a smaller dbh
because their growth rates are often slower. The DFW criterion is and"OR"
so old-growth forests do not necessarily have to have trees of this diameter.
— Mature forests: (west of the Cascade Crest) Stands where the largest trees are
80-200 years old OR have average diameters (dbh)exceeding 21 inches
(53cm); crown cover may be less that 100%; decay, decadence,numbers of

Does the wetland unit being rated meet any of the criteria below?
If you answer YES to any of the questions below you will need to protect the wetland
according to the regulations regarding the special characteristics found in the wetland.

><ln addition to the rotectian recommended`.for it$ cat Q =
SP 1.Has the wetland unit been documented as a habitat for any Federally listed
Threatened or Endangered animal or plant species(TIE species)?
For the purposes of this rating system, "documented"means the wetland is on the
appropriate state or federal database.
SP2.Has the wetland unit been documented as habitat for any State listed
Threatened or Endangered animal species?
For the purposes of this rating system, "documented"means the wetland is on the
appropriate state database. Note: Wetlands with State listed plant species are
categorized as Category I Natural Heritage Wetlands see p. 19 of data form).
SP3. Does the wetland unit contain individuals of Priority species listed by the
WDFW for the state?
SP4. Does the wetland unit have a local significance in addition to its functions?
For example, the wetland has been identified in the Shoreline Master
Program,the Critical Areas Ordinance,or in a local management plan as
having special significance. �(
To complete the next part of the data sheet you will need to determine the
Hvdrogeomorphic Class of the wetland being rated.
The hydrogeomorphic classification groups wetlands into those that function in similar ways. This
simplifies the questions needed to answer how well the wetland functions. The Hydrogeomorphic
Class of a wetland can be determined using the key below. See p.24 for more detailed instructions
on classifying wetlands.

Classification of Wetland Units in Western Washington
If the hydrologic criteria listed in each question du not apply to the entire unit beung;
rated,you probably hsve a unit with multiple HGM classes: In this case;identify which
rologic criteriain gnestians 1-7 apply,and gp to Question 8 Hyd
1. Are the water levels in the entire unit usually controlled by tides(i.e. except during floods)?
NO go to 2 YES—the wetland class is Tidal Fringe
If yes, is the salinity of the water during periods of annual low flow below 0.5 ppt(parts per
thousand)? YES—Freshwater Tidal Fringe 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 rated as an Estuarine wetland. Wetlands that
were called estuarine in the first and second editions of the rating system are called Salt
Water Tidal Fringe in the Hydrogeomorphic Classification. Estuarine wetlands were
categorized separately in the earlier editions, and this separation is being kept in this
revision. To maintain consistency between editions, the term"Estuarine"wetland is kept.
Please note,however, that the characteristics that define Category I and 11 estuarine
wetlands have changed(see p. ).
2. The entire wetland unit is flat and precipitation is the only source(>90%)of water to it.
G dwater and surface water runoff are NOT sources of water to the unit.
NO—go to 3 YES—The wetland class is Flats
If your wetland can be classified as a"Flats"wetland, use the form for Depressional
wetlands.
3. Does the entire wetland unit meet both of the following criteria?
_The vegetated part of the wetland is on the shores of a body of permanent open water
(without any vegetation on the surface) at least 20 acres(8 ha) in size;
At least 30%of the open water area is deeper than 6.6 ft(2 m)?
O go to 4 YES—The wetland class is Lake-fringe(Lacustrine Fringe)
4. Does the entire wetland unit meet all of the following criteria?
_The wetland is on a slope(slope can be very gradual),
_ 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?
NOTE: Surface water does not pond in these type of wetlands except occasionally in
ve2 small and shallow depressions or behind hummocks (depressions are usually
<3ft diameter and less than oot deep).
NO-go to 5 S=The wetland class is Slope

5. Does the entire wetland unit meet all of the following criteria?
The unit is in a valley, or stream channel,where it gets inundated by overbank
flooding from that stream or river
The overbank flooding occurs at least once every two years.
NOTE. The riverine unit can contain depressions that are filled with water when the river is
not flooding.
NO-go to 6 . YES—The wetland class is Riverine
6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the
surface, at some time during the year. This means that any outlet, if present, is higher than the
interior of the wetland.
NO—go to 7 YES—The wetland class is Depressional
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.
NO—go to 8 YES—The wetland class is Depressional
8. Your wetland unit seems to.be difficult to classify and probably contains several different HGM
clases. 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 your wetland. 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 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.
H6M Classes within the wetland unit bein 'rated = HGM Class to Me in Rating
Slope+Riverine Riverine
Slope+Depressional Depressional
Slope+Lake-fringe Lake-fringe
Depressional+Riverine along stream within boundary Depressional
Depressional+Lake-fringe D epressional
Salt Water Tidal Fringe and any other class of freshwater Treat as ESTUARINE under
wetland wetlands with special
characteristics
If you are unable still to determine which of the above criteria apply to your wetland, or if you
have more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional
for the rating.

diameter at breast height(dbh)of 32 inches(81 cm) or more.
NOTE: The criterion for dbh is based on measurements for upland forests.
Two-hundred year old trees in wetlands will often have a smaller dbh
because their growth rates are often slower. The DFW criterion is and "OR"
so old-growth forests do not necessarily have to have trees of this diameter.
— Mature forests: (west of the Cascade Crest) Stands where the largest trees are
80—200 years old OR have average diameters(dbh) exceeding 21 inches
(53cm); crown cover may be less that 100%; decay,decadence,numbers of
snags, and quantity of large downed material is generally less than that found
in old-growth.

Mason County Resource Ordinance—Wetlands 17.01.070
AS APPROVED BY THE Board of County Commissioners- December 27, 2006
MASON COUNTY RESOURCE ORDINANCE
WETLANDS
17.01.070 WETLANDS
The purpose of this section is to avoid, or in appropriate circumstances, minimize, rectify, reduce
or compensate for impacts arising from land development and other activities affecting wetlands;
to maintain and enhance the biological and physical functions and values of wetlands with
respect to water quality maintenance; stormwater and floodwater storage and conveyance; fish
and wildlife habitat, primary productivity, recreation, education and historic and cultural
preservation. When avoiding impacts is not reasonable, mitigation shall be implemented to
achieve a no net loss of wetlands in terms of acreage, function and value.
A. CLASSIFICATION
The following shall be classified as wetland areas:
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. However, wetlands may
include those artificial wetlands intentionally created from non-wetland areas created to
mitigate conversion of wetlands, if permitted by the county.
B. DESIGNATIONS
The following lands, shorelands and waters of Mason County are hereby designated
under RCW 36.70A.060 and RCW 36.70A.170, as critical areas requiring immediate
protection from incompatible land uses: Wetlands and their vegetatiGR ^-^buffer as
specified by Section 17.01.070.E.
In making a determination regarding a wetland, Washington State Wetland Identification
and Delineation Manual (Ecology #96-94), or as amended hereafter, shall serve as the
technical resource guide on determining if an area possesses hydrophytic vegetation,
hydric soils, and/or wetland hydrology.
1. The following are designated as regulated wetlands under this Chapter:
a. All areas described in Section 17.01.070.A.;
b. Wet#aad-pEonds less than twenty acres;
C. Wetlands created as mitigation, and those modified for approved land
use activities, including their submerged aquatic beds.
2. The following are designated as non-regulated wetlands:
Artificial man made wetlands intentionally created from non-wetland sites,
including, but not limited to, irrigation and drainage ditches, grass-lined swales,
canals, detention facilities, wastewater treatment facilities, farm ponds, and
landscape amenities or those wetlands created after July 1, 1990, that were
unintentionally created as a result of the construction of a road, street or
highway. Wetlands _ u l-atea +h;G Ghapte.GIG R,+ ;RGI sae GategeFy n and

a Exempt wetlands that are isolated and less than 1,000 square feet in area where
it has been shown by the applicant that they are not associated with a riparian corridor,
they are not part of a wetland mosaic and do not contain habitat identified as essential for
local populations of priority species identified by Washington Department of Fish and
Wildlife.
b No measures to avoid impacts for Category III and IV wetlands between 1,000 i
and 4,000 square feet are required if they meet all the following criteria:
(1) Wetland is not associated with a riparian corridor, and _
(2) Wetland is not part of a wetland mosaic, and
(3) Wetland does not score 20 points or greater for habitat in the 2004
Western Washington Rating System, and
(4) Wetland does not contain habitat identified as essential for local
populations of priority species identified by Washington Department of Fish and
Wildlife.
C. Impacts allowed under this provision to these wetlands will be fully mitigated as
required in mitigation section.
3. Owners and applicants with non-regulated wetlands are strongly urged to
cooperate voluntarily in this plan of wetland protection, using the guidelines in
this ordinance and in materials provided by the Department of Community
Development.
C. PROCEDURES
1. Responsibilities for the determination of wetland boundaries:
a. Formal determination of wetland boundaries is the responsibility of the
County. The responsibility to provide.all necessary and accurate data to
rests with the a
the County for its determinationpplicant. This information
qualified wetland professional
will include a field delineation by a q p
applying the Washington State Wetland Identification and Delineation
Manual(Ecology#96-94) or as amended hereafter. When, in the opinion
of the Director, sufficient information exists from the County's wetland
inventory, or other sources, the requirement for a full or partial
delineation may be waived. For instance, in some cases, the applicant
may only be required to determine the wetland boundary, or portion
thereof, of the wetland system. The Director shall determine when a
permit application is required and what additional information may be
necessary. Wetland delineations shall be performed in accordance with
the procedures as specified in the Washington State Wetland
Identification and Delineation Manual (Ecology #96-94), or as amended
hereafter. Evidence documenting the results of any boundary survey, or
other submitted data, may be required by the Director.
b. Mason County, at a fee,when requested by the applicant, or the affected
party, may perform the delineation in lieu of direct action by the
applicant. Mason County may use hydrology, soils, plant species, and
other data, and consult with biologists, hydrologists, soil scientists, or
other experts, as needed, to perform the delineation. The County shall
make a good faith effort to provide this service, consistent with budgetary
constraints and available in-house expertise, for smaller projects and
especially for those property owners with.lesser financial capabilities.
C. Where Mason County performs a wetland boundary determination at the
request of the applicant, it shall be considered a final determination
unless contested.

Mason County Resource Ordinance—Wetlands 17.01.070
d. Where the applicant has provided a determination of the wetland
boundary, the Director shall verify the accuracy of, and may render
adjustments to,the boundary delineation.
e. In the event the boundary delineation is contested by the applicant or
affected party, the Department of Ecology, or a mutually agreed upon
party, shall settle the dispute.
D. LAND USES
1. Mason Environmental Permit Required Uses and Activities
A Mason Environmental Permit shall be obtained from the County, using the
administrative review process in this Chapter, prior to undertaking, in a regulated
wetland or its yegetatioR aFe buffer, for the following activities.
a. In all regulated wetlands, the removal, excavation, grading, dredging,
dumping, discharging, or filling of any material; or the draining or flooding
of the site, except where undertaken for maintenance (but not
construction)of drainage ditches or for emergency repair;
b. The construction of stormwater management facilities;or
C. The driving of pilings;
d. The placing of obstructions;
e. The construction, reconstruction, demolition, or expansion of any
structure;
f. The destruction or alteration of wetlands and wetland vegetatie►�
afeabuffer through clearing, harvesting, shading, intentional burning, or
planting of vegetation that would alter the character of a designated
wetland or ve9etatiGR aFe buffer, provided that this subsection shall not
apply to the following activities undertaken in a manner which minimizes
impacts:
(1) The harvesting or normal maintenance of vegetation in a manner
that is not injurious to the natural reproduction of such
vegetation;
(2) The removal or eradication of noxious weeds so designated in
Chapter 17.10 RCW or other exotic, nuisance plants;
(3) Site investigative work necessary for land use application
submittals such as surveys, soil logs and percolation tests;
(4) The construction or trails which shall be unpaved when located
in the buffers and elevated when located in wetlands, which are
not intended for motorized use, and which are no wider than
three (3) feet, unless additional width is necessary for safety
along a precipice, steep hillside, or other hazardous area. See
section 17.01:070.E.6.c. for additional details on regulated (but
permitted)trail activity.
(5) Emergency services or repairs for health and welfare; or
(6) Activities of a mosquito control district.
(7) The removal of a danger tree, provided that such removal is
mitigated by planting in the vicinity of the removed tree a total of
six(6) new trees, each of a minimum three (3)feet in height and
each of the same species or native species as the removed tree.
If the replacement tree planting is judged to be unnecessary to
replace the canopy structure of a vegetation area, the Director
may request the applicant leave or place the danger tree within
the vegetation area as habitat.
g. Activities that result in a significant change of water temperature, a
significant change of physical or chemical characteristics of wetlands
water sources, including quantity, or the introduction of pollutants.

2. Activities Permitted without a Mason Environmental Permit
The following uses shall be allowed, in addition to those defined in General
Exemptions (see Section 17.01.130), within a wetland or wetland vegetation I
afeabuffer to the extent that they are not prohibited by the Shorelines
Management ACT of 1971 (Chapter 90.58 RCW), Federal Water Pollution
Control Act(Clean Water ACT), State Water Pollution Control Act(Chapter 90.48
RCW), State Hydraulic Code (RCW 75.20.100-.140), Forest Practices Act
(Chapter 76.09 RCW and Chapter 222-16 WAC) or any other applicable
ordinance or law and provided they are conducted using best management
practices, except where such activities result in the conversion of a regulated
wetland or wetland egetati^^ aFeabuffer to a use to which it was not previously
subjected and provided further that forest practices and conversions from forest
land shall be governed by Chapter 76.09 RCW and its rules:
a. Conservation or preservation of soil, water, vegetation, fish, shellfish,
and other wildlife;
b. Outdoor recreational activities that do not have a significant adverse
impact on the wetland and its related vegetat;9n a;zabuffer;
C. The harvesting of wild crops in a manner that is not injurious to natural
reproduction of such crops and provided the harvesting does not require
tilling of soil, planting of crops, or alteration of the wetland by changing
existing topography,water conditions or water resources;
d. Existing and ongoing agricultural activities, including farming,
horticulture, aquaculture, irrigation, ranching or grazing of .animals.
Activities on areas lying fallow as part of a conventional rotational cycle
are part of an ongoing operation. Activities which bring an area into
agricultural use are not part of an ongoing operation. An operation
ceases to be ongoing when the area in which it was conducted has been
converted to another use or has lain idle
hydF)Ieg*Gal Fegimeto Fesume #gRs for more than
five years unless that idle land is registered in a federal or state soils
conservation program. Forest practices are not included in this definition.
e. The maintenance(but not construction)of drainage ditches;
f. Education, scientific research, and use of nature trails;
g. Site investigative work necessary for land use application submittals
such as surveys, soil logs, percolation tests and other related activities.
In every case, wetland impacts shall be minimized and disturbed areas
shall be immediately restored; and
h. The following uses are allowed within wetlands and/or wetland
vegetat+ea-afeabuffer, provided that any required permits or approvals
are obtained and further provided that wetland impacts are minimized
and that disturbed areas are immediately restored:
(1) Normal maintenance, repair, or operation of existing serviceable
structures, facilities, or improved areas. Maintenance and repair
does not include any modification that changes the character,
scope, or size of the original structure, facility, or improved area
and does not include the construction of a maintenance road;
and
(2) Minor modification of existing serviceable structures within a
Tegetatien aFeabuffer zone where modification does not
adversely impact wetland functions.
(3) Repair or reconstruction of damaged or destroyed structures
within two years of the damage or destruction.

E. DEVELOPMENT STANDARDS
1. Wetlands Rating System
A four-tier wetlands rating system is hereby adopted as the rating system for
Mason County. Wetlands vegetatiae areabuffer widths, wetland activities and
replacement ratios shall be based on this rating system.
Procedures for applying the wetland rating system are set forth in the
Washington State Wetland Rating System for Western Washington, revised
2004. or as amended hereafter. men Washington State Department
of Ecology ,
a. Wetlands shall be categorized as follows:
Table 17.01.070 A
1) Category I Wetlands. Category I wetlands are those regulated wetlands that
include but are not limited to rare, unique wetland types that are more
sensitive to disturbance than most wetlands and that contain ecological
attributes that are impossible to replace within a human lifetime. Category I
wetlands score 70 points or more out of 100 on the wetlands ratings
systems.
2) Category II Wetlands. Category II wetlands are those regulated wetlands
that score between 51-69 points out of 100 on the wetlands ratings system.
3) Category III Wetlands. Category III wetlands are those regulated wetlands
that score between 30-50 points on the wetlands ratings system.'
4) Category IV Wetlands. Category IV wetlands are those regulated wetlands
that score less than 30 points out of 100 on the wetlands ratings system.*
5) Wetlands intentionally created from non-wetland areas to mitigate conversion
of other wetlands.
6) Mosaic wetlands as defined in 17.01.240.
`Non-Regulated Wetlands. Isolated wetlands under 1,000 square feet which are
not associated with a riparian corridor, not part of a wetland mosaic and not
essential habitat of a priority species as identified by the Washington Department
of Fish and Wildlife.
Please refer to Appendix A or the Department of Ecology publication

2. Wetland Buffers
a- Stag, aFd Vegetati9R Buffer Widths.
Wetland buffers shall be required for all regulated wetlands. Any wetland
created, restored, or enhanced as compensation for approved wetland
alterations shall also include a the StaR,daFd Veget2ti9R aFeabuffer
required for the category of the created, restored, or enhanced wetland.
The buffer widths are established by adjusting a base width for the
category of wetland at the site for the habitat value as scored by the
wetland rating system and for the land use intensity of the proposed
activity. All buffers shall be measured horizontally from the wetland
boundary as surveyed in the field.
The width of the wetland vegetatiea areabuffer shall be determined by
the following process:
1) The wetland is categorized according to wetland ratings system
category as shown in Table 17.01.070 A;
2) Table 17.01.070 B rates examples of different land uses for intensity
of impacts to wetlands.

or may require other conditions be placed on the development on a case-by-case
basis when ^ 'aFgeF veg t^t' ,_arm_necessary to protect wetland functions
and values based on local conditions. This determination shall be supported by
appropriate documentation showing that it is reasonably related to protection of
the functions and values of the regulated wetland. Such determination shall be
attached as a permit condition and shall demonstrate that:
a) A larger yegetctic^ aFBabuffer is necessary to maintain viable populations or
critical habitat of threatened or endangered species living within the subject
wetland(s)boundaries; or
b) The adjacent land is susceptible to severe erosion and erosion control
measures otherwise required will not effectively prevent adverse wetland
impacts; or
c) There are other nearby wetlands or critical areas and adjustments to the
buffers would prevent fragmentation of the habitat or is otherwise if the

5. Wetland Buffer Reduction
The width of the buffer may be reduced for proposed land uses with high-
intensity impacts under the following conditions:
a. For wetlands that score moderate or high for habitat(20 points or more
for the habitat functions) the width of the buffer may be reduced to that
required for moderate-intensity impacts provided that:
(1) A relatively undisturbed,vegetated area corridor at least 100-feet
-, wide is protected between the wetland and any other Priority
Habitats as defined by the Washington State Department of Fish and
Wildlife. Protection of the corridor shall be assured by a conservation
_ easement.
(2) Measures to minimize the impacts of the land use shall be applied.
Examples of these measures are shown in Table X.
b. For wetlands that score less than 20 points for habitat,the buffer width
can be reduced to that required for moderate-impact land uses provided
that measures to minimize the impacts of the land use shall be applied.
Examples of these measures are shown in Table X.

- 56. Wetland VegetatieR AFeaBuffer Conditions
Except as otherwise specified, wetland buffers shall be retained in their natural
condition. _ Where vegetation- afeabuffer disturbance has occurred during
construction, revegetation with native vegetation may be required.
97. Permitted Uses In A Wetland VegetatiG n.,,Buffer
Regulated activities shall not be allowed within a vegetation-areabuffer except as
follows:
a. Activities that are permissible within a wetland shall be permissible within
a wetland vegetation aFeabuffer;and
b. Stormwater management facilities (bioswales and dispersal trenches)
only when required to allow a reasonable use of the property.
Encroachment into the vegetation—afeabuffer shall be the minimum
necessary and will be permitted only within the outer twenty-five (25)feet
or outer twenty-five percent (25%) of the vegetatioR aFeabuffer,
whichever is more restrictive.
C. Other passive activities such as recreational trails and tot lots are also
permitted within the outer twenty-five percent (25%) of the .ti^^ n
afeabuffer.
d. Selective commercial timber cutting will be limited to the outer twenty-five
percent (25%) of Category I and II wetland buffers and fifty percent
(50%) of Category III and IV wetland buffers. No more than thirty
percent (30%) of the merchantable trees may be harvested in this area
on a one-time-only basis as associated with a land use conversion
application. The thirty percent(30%) harvest must be representative and
maintain an intact forest community character. The percentage and
species distribution of all trees must be consistent before and after the
selective timber harvest:
8-. Building Setback Lines
A building setback line of fifteen (15) feet is required from the edge of any
wetland vegetation afeabuffer. Minor structural intrusions into the area of the
building setback may be allowed if the Administrator determined that such
intrusions will not negatively impact the wetland.
F. MITIGATION FOR WETLAND IMPACTS
As a condition of any permit allowing alteration of wetlands and/or wetland buffers, the
County shall require that the applicant engage in the restoration, creation or
enhancement of wetlands and.their buffers in order to offset the impacts resulting from
the applicant's actions.
GGI`npensatien aRalysis (!R that eFd F Gf pFef,,.,,.Ge). If wetland or wetland buffer impacts
are proposed, a sequence of review must be considered. First, the applicant must
consider avoiding the wetland or wetland buffer. If the applicant can not avoid the wetland
or wetland buffer, they must consider reducing (or minimizing)the impact. Impacts which
can not be avoided must be mitigated as provided in this ordinance. Mitigation for buffers
shall be on a minimum 1:1 ratio. Approval of the mitigation plan shall be signified by a
notarized memorandum of agreement signed by the applicant and Director of the
Department of Community Development or designee, and recorded with the Mason
County Auditor. The agreement shall refer to all requirements for the mitigation project.
The County may suspend or revoke a permit if it finds that the applicant has not complied
with the conditions or limitations set forth in the permit or has exceeded the scope of work
set for in the permit. The overall goal of any compensatory project shall be no net loss of
wetlands function and acreage

2. Wetland Restoration, Creation and Enhancement(see details in 17.01.200 1)
3. The department may increase or decrease the ratios based on one or more of
the following:
a. Replacement ratios may be increased under the following circumstances:
(1)Uncertainty exists as to the probable success of the proposed restoration
or creation:
(2)A significant period of time will elapse between impact and establishment
of wetland functions at the mitigation site;
(3) Proposed compensation will result in a lower category wetland or
reduced functions relative to the wetland being impacted; or
(4)The impact was an unauthorized impact.
b. Replacement ratios may be decreased under the following circumstances:
(1) Documentation by the applicant provides more certainty that the
proposed compensation actions will be successful. For example,
demonstrated prior success with similar compensation actions as those
proposed, and/or extensive hydrologic data to support the proposed
water regime;
(2) Documentation by the applicant demonstrates that the proposed
compensation actions will provide functions and values that are
significantly greater than the wetland being impacted:or
(3)The proposed mitigation actions are conducted in advance of the impact
and are shown to be successful.
4. Off-Site Compensatory Mitigation.
a. Considerations for determining whether off-site mitigation is preferable include but
are not limited to:
(1) On-site conditions do not favor successful establishment of the required
vegetation type, or lack the proper soil conditions, or hydrology:
(2) On-site compensation would result in an aquatic habitat that is isolated
from other natural habitats or severely impaired by the effects of the
adjacent development:
(3) Off-site location is crucial to one or more species that is threatened,
endangered, or otherwise of concern, and the on-site location is not:
(4) Off-site location is crucial to larger ecosystem functions, such as
providing corridors between habitats, and the on-site location is not: and
(5) Off-site compensation has a greater likelihood of success or will provide
greater functional benefits.

_ b. When determining whether off-site mitigation is preferable the value of the site
specific wetland functions at the proiect site such as flood control nutrient retention
sediment filtering, and rare or unique habitats or species should be fully considered I
c. When conditions do not favor on-site compensation off-site compensatory mitigation
should be located as close to the impact site as possible at least within the same
watershed, while still replacing lost functions
4. Monitoring Requirements.
Mason County shall require monitoring reports on an annual basis for a minimum of five
Years and up to ten years, or until the department determines that the mitigation project
has achieved success. The wetlands mitigation plan shall provide specific criteria for
monitoring the mitigation proiect Criteria shall be proiect-specific and use best available
science to aid the department in evaluating whether or not the proiect has achieved
success.
G. PERMIT REVIEW
The basic concern in the permitting process is to avoid and minimize wetland impacts.
Permits are issued when the applicant can demonstrate that the activity is both
unavoidable and necessary. The applicant must state the purpose of the proposed
project, and demonstrate the requirement for a wetland location or access across
wetlands, and the reason it cannot be located at other sites, or at another location on-
site.

17.01.240 DEFINITIONS
l .
(For brevity, only definitions proposed to be changed, added, or deleted are included.)
Bog:A unique type of wetland dominated by mosses that form organic peat. Bogs form
in areas where the climate allows the accumulation of peat to exceed its
decomposition. Boa hydrology is dominated by precipitation rather than surface
inflow. The plant community is specialized to survive in the nutrient-poor and
highly acidic conditions typical of boa systems.
_Mitigation, compensatory: "Compensation"or"C mpensatory mitigation" means a form of
mitigation.that replaces project-induced wetland or habitat losses or impacts, and includes, but is
not limited to, restoration, enhancement, substitute resources, creation, and preservation.
"Substitute Resources" means actions performed to provide for an alternative environmentally
— sensitive area. "Preservation"means actions taken to ensure the permanent protection of
existing, high-quality environmentally sensitive areas. Compensation also is not limited to
mitigation at or adiacent to the site on which a wetland has been impacted by a regulated activity.
Relatively undisturbed vegetated area:A relatively undisturbed vegetated area is one with a
native plant community appropriate for the ecoregion or with one that performs similar functions.
If the area is unvegetated, sparsely vegetated, or vegetated with invasive species that do not
Perform needed functions, then it is not relatively undisturbed. Any heavily used paved or gravel
roads, residential areas, lawns,tilled fields, parking lots, or actively grazed pastures would
disqualify the area from being"relatively undisturbed."Bridges crossing streams or rivers within
the buffer are considered as a"disturbance." Infrequently used gravel or paved roads or
vegetated dikes in a relatively undisturbed buffer, however, can be ignored as a"disturbance."
Open water that is not part of the wetland is considered part of the buffer. The open water can be
-- considered undisturbed unless there is heavy boat traffic there. (Adapted from: Hrubv, T. 2004.
Washington State wetland rating system for western Washington—Revised. Washington State
Department of Ecology Publication#04-06-025.)
-- Wetlands: Areas that are inundated or saturated by surface water 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. Wetlands do not include those artificial
wetlands intentionally created from non-wetland sites, including, but not limited to, irrigation and
drainage ditches, grass-lined swales, canals, detention facilities, waste water treatment facilities,
farm ponds, and landscape amenities or those wetlands created after July 1, 1990,that were
-- unintentionally created as a result of the construction of a road, street or highway. However,
wetlands may include those artificial wetlands intentionally created from non-wetland areas
created to mitigate conversion of wetlands, if permitted by the county or city. WeVa ds Fe„„latea

Wetlands, Creation or Establishment of: The manipulation of the physical, chemical, or
-- biological characteristics present to develop a wetland on an upland or deepwater site where a
wetland did not previously exist. Establishment results in a gain in wetland acres. Activities
typically involve excavation of upland soils to elevations that will produce a wetland hydroperiod,
create hydric soils, and support the growth of hydrophytic plant species.
Wetlands, Cowardin classification: The first commonly used classification system for wetlands
developed in 1979 by the U.S. Fish and Wildlife Service. The Cowardin system
classifies wetlands based on water flow, substrate types, vegetation types, and dominant plant
species.

Wetlands Enhancement or the Enhancement of Wetlands: The manipulation of the physical, �—
chemical, or biological characteristics of a wetland site to heighten, intensify, or improve specific
function(s)or to change the growth stage or composition of the vegetation present. Enhancement
is undertaken for specified purposes such as water quality improvement, flood water retention, or
wildlife habitat. Enhancement results in a change in some wetland functions and can lead to a '
decline in other wetland functions, but does not result in a gain in wetland acres. Activities
typically consist of planting vegetation, controlling non-native or invasive species, modifying site
elevations or the proportion of open water to influence hydroperiods, or some combination of
these activities.
Wetland, Estuarine:Wetlands where salt tolerant plant species are dominant and the
water regime is influenced by tidal action. The wetlands are usually partially
enclosed by land with open,or partially obstructed access to open saline water. In
areas where freshwater wetlands grade into estuarine areas,the boundary of the
latter extends to an area where the salinity is less than 5 ppt(parts per thousand)
during the period of average annual low flow.
Wetland, Forested:A wetland class in the Cowardin classification where woody plants
taller than 20 feet form the dominant cover. Shrubs often form a second laver
r�
beneath the forest canopy,with a laver of herbaceous plants growing beneath the
shrubs.
Wetlands, Isolated: Isolated wetlands are generally defined as those wetlands that have
no surface water connections to other aquatic resources. For the purposes of this ordinance,
wetlands are not regulated as"isolated wetlands" if they are part of a mosaic wetlands. (See
"Wetlands, Mosaic"for additional information.)
Wetlands, Mosaic: "Wetlands, mosaic"or"mosaic wetlands" means groups of wetlands that.
should be rated and regulated as an aggregate.Although each patch the wetlands that make up
the mosaic is separated from nearby wetlands by some upland area these wetlands are not
regulated as"isolated wetlands"as the term is used in this ordinance. That is, in determining
whether a wetland falls into the category of non-regulated wetlands (See Table 17.01.070)the
area of the wetland is the area of the mosaic wetland and not the area of an individual wetland
component of the mosaic. Guidance for determining when nearby wetlands compose a mosaic -
wetland is provided in the Washington State wetland rating system for western Washington—
Revised, Washington State Department of Ecology Publication#04-06-025. The patches of
wetlands compose a mosaic when 1)the patches are less than one acre in size,2)the patches
are separated from each other by 100 feet or less on average, and 3)the area of the wetlands in
the potential mosaic are greater than 50 percent of the total combined area of wetland and
upland.An illustration of this analysis of whether the potential mosaic should be considered as a
aggregate rather than as individual isolated wetlands is shown below. (The illustration is from the
DOE Publication referenced above.)
Wetland, Natural Heritage:As defined by the Natural Heritage Program of the
Washington State Department of Natural Resources, these are wetlands that are either
high quality undisturbed wetlands or wetlands that support threatened, endangered, or sensitive
plant species.
Wetland Protection/Maintenance (Preservation) of: Removing a threat to, or preventing the f'
decline of, wetland conditions by an action in or near a wetland. This includes the purchase of
land or easements, repairing water control structures or fences, or structural protection such as
repairing a barrier island. This term also includes activities commonly associated with the term
Preservation. Preservation does not result in a gain of wetland acres, may result in a gain in
functions,and will be used only in exceptional circumstances.

Wetland Restoration or Restoration of Wetlands: The manipulation of the physical, chemical,
or biological characteristics of a site with the goal of returning natural or historic functions to a
former or degraded wetland': For the purpose of tracking net gains in wetland acres, restoration is
divided into:
• Re-establishment: The manipulation of the physical, chemical, or biological characteristics of
a site with the goal of returning natural or historic functions to a former wetland. Re-
establishment results in a gain in wetland acres (and functions). Activities could include
removing fill material, plugging ditches,or breaking drain tiles.
• Rehabilitation: The manipulation of the physical, chemical, or biological characteristics of a
site with the goal of repairing natural or historic functions of a degraded wetland.
Rehabilitation results in a gain in wetland function but does not result in a gain in wetland
acres. Activities could involve breaching a dike to reconnect wetlands to a floodplain or return
tidal influence to a wetland.

APPENDIX A (NOTE: ALL OF APPENDIX A IS NEW PROPOSED TEXT)
The following is from:
Hruby,T.2004.Washington State wetland rating system for western Washington—Revised. -
Washington State Department of Ecology Publication#04-06-025. Pages 6 to 10.
3. RATIONALE FOR THE CATEGORIES
This rating system is designed to differentiate between wetlands based on their sensitivity to
disturbance, rarity,the functions they provide, and whether we can replace them or not. The
emphasis is on identifying those wetlands:
•where our ability to replace them is low,
•that are sensitive to adjacent disturbance,
•that are rare in the landscape,
•that perform many functions well,
•that are important in maintaining biodiversity.
The following description summarizes the rationale for including different wetland types in each
category.As a general principle, it is important to note that wetlands of all categories have
valuable functions in the landscape, and all are worthy of inclusion in programs for wetland
protection.
3.1 CATEGORY I
Category I wetlands are those that 1) represent a unique or rare wetland type;or 2)are more
sensitive to disturbance than most wetlands; or 3) are relatively undisturbed and contain
ecological attributes that are impossible to replace within a human lifetime; or 4)provide a high
level of functions. We cannot afford the risk of any degradation to these wetlands because their
functions and values are too difficult to replace. Generally,these wetlands are not common and
make up a small percentage of the wetlands in the region.Of the 122 wetlands used to field test
the current rating system only 24 (20%)were rated as a Category I. In western Washington the
following types of wetlands are Category I.
Estuarine Wetlands-Relatively undisturbed estuarine wetlands larger than 1 acre are Category
I wetlands because they are relatively rare and provide unique natural resources that are
considered to be valuable to society. These wetlands need a high level of protection to maintain
their functions and the values society derives from them. Furthermore,the questions used to
characterize how well a freshwater wetland functions cannot be used for estuarine wetlands. No
rapid methods have been developed to date to characterize how well estuarine wetlands function.
Estuaries, the areas where freshwater and salt water mix,are among the most highly productive
and complex ecosystems where tremendous quantities of sediments, nutrients and organic
matter are exchanged between terrestrial,freshwater and marine communities.This availability of
resources benefits an enormous variety of plants and animals. Fish, shellfish and birds and plants
are the most visible. However,there is also a huge variety of other life forms in an estuarine
wetland:for example, many kinds of diatoms, algae and invertebrates are found there.
Estuarine systems have substantial economic value as well as environmental value.All
Washington State estuaries have been modified to some degree, bearing the brunt of
2006 RO-Wetlands Final.doc Page 20 of 23
New text is underlined,deleted text is struck through Dec.27,2006
Mason County Resource Ordinance—Wetlands 17.01.070
development pressures through filling, drainage, port development and disposal of urban and
industrial wastes. The over-harvest of certain selected economic species has also modified the
natural functioning of estuarine systems. Many Puget Sound estuaries such as the Duwamish,
Puyallup, Snohomish and Skagit have been extensively modified. Up to 99% of some estuarine
wetland areas in the state have been lost.
Estuaries, of which estuarine wetlands are a part,are a"priority habitat"as defined by the state
department of Fish and Wildlife. Estuaries have a high fish and wildlife density and species
richness, important breeding habitat, important fish and wildlife seasonal ranges and movement
corridors, limited availability, and high vulnerability to alteration of their habitat(Washington State
Department of Fish and Wildlife(WDFW), http://www.wa.gov/wdfw/hab/phslist.htm, accessed
October 15, 2003).
Natural Heritage Wetlands—Wetlands that are identified by scientists of the Washington
Natural Heritage Program/DNR as high quality, relatively undisturbed wetlands, or wetlands that
support State listed threatened or endangered plants are Category I wetlands.
High quality, relatively undisturbed examples of wetlands are uncommon in western Washington.
By categorizing these wetlands as Category I,we are trying to provide a high level of protection to
the undisturbed character of these remaining high quality wetlands. Examples of undisturbed
wetlands help us to understand natural wetland processes.
Furthermore,the presence of rare plants in a wetland indicates unique habitats that might
otherwise not be identified through the rating system. Rare plant populations are also sensitive to
disturbance, particularly activities that result in the spread of invasive species.
The Washington Natural Heritage Program of the Department of Natural Resources(DNR)has
identified important natural plant communities and species that are very sensitive to disturbance
or threatened by human activities, and maintains a database of these sites.
"These natural systems and species will survive in Washington only if we give them special
attention and protection. By focusing on species at risk and maintaining the diversity of natural
ecosystems and native species, we can help assure our state's continued environmental and
economic health." (DNR http://www.wa.gov/dnr/htdocs/fr/nhp/wanhp.html, accessed October 1,
2002)
Bogs- Bogs are Category I wetlands because they are sensitive to disturbance and impossible
to re-create through compensatory mitigation.
Bogs are low nutrient,acidic wetlands that have organic soils. The chemistry of bogs is such that
changes to the water regime or water quality of the wetland can easily alter its ecosystem. The
plants and animals that grow in bogs are specifically adapted to such conditions and do not
tolerate changes well. Immediate changes in the composition of the plant community often occur
after the water regime changes. Minor changes in the water regime or nutrient levels in these
systems can have major adverse impacts on the plant and animal communities (e.g. Grigal and
Brooks,.1997).
In addition to being sensitive to disturbance, bogs are not easy to re-create through
compensatory mitigation. Researchers in northern Europe and Canada have found that restoring
bogs is difficult, specifically in regard to plant communities (Bolscher 1995, Grosvermier et al.
1995, Schouwenaars 1995, Schrautzer et al. 1996),water regime(Grootjans and van Diggelen
1995, Schouwenaars 1995)and/or water chemistry(Wind-Mulder and Vitt 2000). In fact,
restoration may be impossible because of changes to the biotic and abiotic properties preclude
the re-establishment of bogs (Shouwenaars 1995,Schrautzer et al. 1996). Furthermore, bogs
" form extremely slowly,with organic soils forming at a rate of about one inch per 40 years in
western Washington (Rigg 1958).
2006 RO-Wetlands Final.doc Page 21 of 23
New text is underlined,deleted text is struck through Dec.27,2006
Mason County Resource Ordinance—Wetlands 17.01.070
Nutrient poor wetlands, such as bogs, have a higher species richness, many more rare species,
and a greater range of plant communities than nutrient rich wetlands(review in Adamus and
Brandt 1990). They are,therefore, more important than would be accounted for using a simple
assessment of wetland functions(Moore et al. 1989).
Mature and Old-ctrowth Forested Wetlands—Mature and old-growth forested wetlands over 1
acre in size are"rated"as Category I because these wetlands cannot be easily replaced through
compensatory mitigation.A mature forest may require a century or more to develop, and the full
range of functions performed by these wetlands may take even longer(see review in Sheldon et
al. 2004, in press).
These forested wetlands are also important because they represent a second"priority habitat"as
defined by the state department of Fish and Wildlife. "Priority habitats are those habitat types or
elements with unique or significant value to a diverse assemblage of species."(Washington State
Department of Fish and Wildlife(WDFW), hftp://www.wa.gov/wdfw/hab/phslist.htm, accessed
October 15, 2002). NOTE:All wetlands are categorized as a priority habitat by the WDFW.
Mature and forested wetlands, therefore, represent two priority habitats that coincide.
Wetlands in Coastal Lagoons—Coastal lagoons are shallow bodies of water, like a pond, partly
or completely separated from the sea by a barrier beach. They may, or may not, be connected to
the sea by an inlet, but they all receive periodic influxes of salt water.This can be either through
stone surges overtopping the barrier beach, or by flow through the porous sediments of the
beach.
Wetlands in coastal lagoons are placed into Category I because they probably cannot be
reproduced through compensatory mitigation, and because they are relatively rare in the
landscape. No information was found on any attempts to create or restore coastal lagoons in
Washington that would suggest this type of compensatory mitigation is possible.Any impacts to
lagoons will,therefore, probably result in a net loss of their functions and values.
In addition, coastal lagoons and their associated wetlands are proving to be very important
habitat for salmonids. Unpublished reports of ongoing research in the Puget Sound (Hirschi et al.
2003, Beamer et al.2003)suggests coastal lagoons are heavily used by juvenile salmonids.
Wetlands That Perform Many Functions Very Well-Wetlands scoring 70 points or more(out
of 100)on the questions related to functions are Category I wetlands.
Not all wetlands function equally well, especially across the suite of functions performed. The field
questionnaire was developed to provide a method by which wetlands can be categorized based
on their relative performance of different functions.Wetlands scoring 70
points or more were judged to have the highest levels of function.Wetlands that provide high
levels of all three types of functions (improving water quality, hydrologic functions, and habitat)
are also relatively rare. Of the 122 wetlands used to calibrate the rating system in western
Washington, only 18 (15%)scored 70 points or higher based on their functions.
The questionnaire on wetland functions is based on the six-year effort to develop detailed
methods for assessing wetland functions both in eastern and western.Washington. These
methods currently represent the"best available science"in rapid assessments of wetland
functions.
3.2 CATEGORY II
Category II wetlands are difficult,though not impossible, to replace, and provide high levels of
some functions. These wetlands occur more commonly than Category I wetlands, but still need a
relatively high level of protection. Category II wetlands in western Washington include:
2006 RO-Wetlands Final.doc Page 22 of 23
New text is underlined,deleted text is struck through Dec.27,2006
Mason County Resource Ordinance—Wetlands 17.01.070
Estuarine Wetlands-Any estuarine wetland smaller than an acre, or those that are disturbed
and larger than 1 acre are category II wetlands.Although disturbed, these wetlands still provide
unique natural resources that are considered to be valuable to society. Furthermore,the
questions used to characterize how well a wetland functions cannot be used for estuarine
wetlands.
Interdunal Wetlands- Interdunal wetlands greater than 1 acre are Category II because they
provide critical habitat in this ecosystem (Wiedemann 1984). This resource is important but
constitutes only a small part of the total dune system (Wiedemann 1984). No methods have been
developed to characterize how well interdunal wetlands function, so these wetlands cannot be
rated by a score.
- Interdunal wetlands form in the"deflation plains"and "swales"that are geomorphic features in
areas of coastal dunes. These dune forms are the result of the interaction between sand, wind,
water and plants. The dune system immediately behind the ocean beach (the primary dune
system)is very dynamic and can change from storm to storm (Wiedemann 1984). For the
purpose of rating, any wetlands that are located to the west of the 1889 line (western boundary of
upland ownership)are considered to be interdunal.
Wetlands That Perform Functions Well-Wetlands scoring between 51-69 points (out of 100)
on the questions related to the functions present are Category II wetlands.Wetlands scoring 51-
69 points were judged to perform most functions relatively well, or performed one group of
functions very well and the other two moderately well.
3.3 CATEGORY III
Category III wetlands are 1)wetlands with ahmoderate level of functions (scores between 30-50
points)and 2)interdunal wetlands between 0.1 and 1 acre in size. Wetlands scoring between 30-
50 points generally have been disturbed in some ways, and are often less diverse or more
isolated from other natural resources in the landscape than Category If wetlands.
3.4 CATEGORY IV
Category IV wetlands have the lowest levels of functions(scores less than 30 points)and are
often heavily disturbed. These are wetlands that we should be able to replace, and in some cases
be able to improve. However, experience has shown that replacement cannot be guaranteed in
any specific case.These wetlands may provide some important functions, and also need to be
protected.

APPENDIX F
Wetland Functions and Values Information
It is important that those involved in wetland regulation and management understand their functions
and values. Knowledge of these roles can be a key factor in the design and implementation of
wetland inventories. Not all wetlands provide each function or value nor do they provide them to the
same degree. Variations occur because of wetland type and characteristics, as well as regional and
local influences. Some local governments try to distinguish how functions and values relate to their
community and region. The following is a brief summary.
Water Supply
With the growth of urban centers and dwindling water supplies, wetlands are increasingly important
as a source of surface and ground water. They can function as recharge areas where water soaks into
the soils, replenishing ground water supplies. Wetlands are also areas where ground water moves to
the surface through springs and seepage, often collecting in pools and ponds, and supplying critical
reserves during periods of drought.
Flood Control
Wetlands are valuable in reducing the impact of flooding. They have the ability to store and slow the
flow of water from upland run-off. If a wetland is associated with a river in a flat valley, the wetland
and its vegetation reduces the height and velocity of flood peaks. Some wetland soils can store large
amounts of floodwater and gradually release them downstream. Construction in flood plain wetlands
causes increase flood heights and rates, and an associated increase in flood damage.
Erosion Control
Vegetated wetlands serve as natural buffers from the effects of tides, waves, wind and river currents.
They dissipate the energy of these erosive forces. The fibrous root systems of wetland plants bind
and stabilize banks, protecting the shoreline from erosion. On the coast, they can limit wave
generation, slow and absorb the impacts of wave energy, and thereby protect inland areas from storm
damage. Construction of bulkheads, rip-rap, and other banked hardening stabilization techniques
simply transfer the erosive energy to neighboring areas.
Pollution and Sediment Control
Wetlands protect and improve the quality of surface and ground waters by removing sediments,
nutrients, heavy metals, and hazardous chemicals. Wetlands vegetation filters particulate matter
from the water. When moving water comes into contact with vegetation, its flow is slowed and
sediment falls out of suspension. The root systems trap the sediment, reducing siltation in
downstream water bodies. Substances such as nutrients, pathogens, and many chemicals are often
i
bound.to the surface of sediment particles. Thus, sedimentation reduces both organic and inorganic I
pollutants. These pollutants may be released when wetland soils are disturbed. Wetland vascular
plants and algae also absorb nutrients and chemicals. The micro-organisms utilize dissolved I
nutrients and break down organic matter. Research is underway to determine the impacts of utilizing
wetlands as tertiary waste treatment facilities.
Wildlife Habitat
Wetlands, the interface between land and water, are among the richest wildlife habitats in the world.
They,provide the conditions essential for the breeding, nesting, feeding, and protection for many
species of waterfowl,mammals, reptiles, and amphibians. These conditions include abundant water, '
diverse and rich vegetation, and adequate cover. Many of these species are "obligates" or dependent
upon the wetland for their survival. Some such as the beaver spend their entire lifetimes in the —
wetland environment. Others like the salmon inhabit it for shorter, but critical, parts of their life
cycle. Numerous species (such as deer and raccoon) depend on wetlands as a source of drinking —
water, food, and winter cover. Wetlands are as critical to the needs of these species as they are to
those that depend solely on wetland habitat. Though many waterfowl nest primarily in northern _
freshwater wetlands, they use wetlands through out the county while migrating and for over-
wintering. Birds such as herons, egrets, rails and harriers depend upon wetlands for their survival.
Both salt and freshwater wetlands are important spawning, nursery, feeding, and wintering areas for
sport and commercial fish and shellfish.
Wetlands also support many endangered plant and animal species. Although wetlands constitute
only 5 per cent of the nation's lands, close the 35 per cent of all rare and endangered animal species
are dependent upon them. (McMillan, A. 1986)
Food Web Productivity
Wetlands play an important part in the food web. Coastal wetlands are among the most productive
areas in the world. Solar energy is utilized by wetland plants to produce hundreds of pounds of
nutrients per acre of salt marsh annually. The vegetation dies, decays, and is broken down to form a
nutrient-rich "soup" called detritus. This rich food source is converted by micro-organisms into
basic nutrients and elements for use by vascular plants and phytoplankton (minute floating plant
life). The phytoplankton are consumed by zooplankton (minute floating animal life). the detritus
and plankton's are carried into tidal creeks, and bays and are consumed by invertebrates such as
oysters, shrimp and crabs. they in turn are preyed upon by other animals including humans. It has
been estimated that 90 per cent of the important commercial marine species either spend their entire
lives in estuarine wetlands or require estuaries as nursery grounds (Kusler, J. 1983). Freshwater
wetlands also provide food, habitat, and spawning grounds for many other species of fish.
Education and Research
1
Coastal and inland wetlands provide unique opportunities for education and scientific research. Due
to the land-water interface, diversity of vegetation, topography, and the resulting varied habitats,
wetlands are ideal for studying plant and animal life. Because ecological relationships are easily
observed, they are excellent locations for teaching environmental science. The complex ecological
relationships of wetland systems make them valuable areas for scientific research as well.
Recreation and Aesthetic Values
Wetlands are areas not only of great diversity but also of great beauty. They provide open space and
contrast for both visual and recreational enjoyment,especially valuable in urban areas. Visitors
include photographers,bird watchers, hikers,boaters, hunters, fishers and natural history enthusiasts.
Appreciation and use of wetlands as a recreational resource is steadily increasing on both a national
and state-wide basis. National, wetland-dependent waterfowl are hunted by over 2 million hunters.
Nisqually National wildlife Refuge, near Olympia, Washington has had a 300 percent increase on
visitor use since 1977. (McMillan, A. 1986)
