Section 33, Township 22N,Range 03W, W.M.
47.34771 N -123.06399 W
B. Project Description
This Habitat Assessment Report has been submitted on behalf of Shallow Creek, LLC to
facilitate approval for the maintenance dredging of an existing manmade pond that acts as
a sediment trap for an unnamed perennial stream, in order to prevent downstream
flooding of SR 106,the applicant's adjoining parcel, and four adjacent properties. The
stream originates on a forested slope to the south of the property and is regulated as a
Type F stream under the Mason County Resource Ordinance for Fish and Wildlife
Habitat Conservation Areas. As per the Ordinance,this Habitat Management Plan has
been submitted for County review.
The approximately(approx.)2.2 acre parcel supports an existing single-family residence.
The pond, which is approx. fifty by thirty feet(50 x 30')in diameter(Attachment 2), is
located approx. 200 feet south of SR 106 and 450 feet south of the marine shoreline of
the Hood Canal. During normal flows,the unnamed Type F perennial stream exits the
pond via a circular drain and is tight-lined below grade across the lower property and
beneath SR 106 to the applicant's adjoining property, where it daylights for approx. 100'
before feeding into another subsurface line and discharging into the Hood Canal at an
unknown point on the intertidal (littoral) shoreline. Storm flows are transported via an
overflow pipe, subsurface,to a Hood Canal outfall located approximately 400 feet east of
where the subject stream crosses beneath SR 106.
The pond collects alluvial sediments transported downstream from the stream's upper
(high energy) reaches,thus alleviating aggradation of the stream's lower reach,which
helps to prevent flooding. Periodically,the pond needs to be dredged of excess sediments.
The proposed project consists of using an excavator to remove the excess sediments and
transporting them to an approved storage site.
Equipment and materials will be driven to the site. The equipment will consist of a track
excavator, a loader, and other appropriate heavy equipment,plus various hand tools.
Work on the project is tentatively scheduled to begin after the receipt of all required
permits and approvals. Work will be completed during daylight working hours normal to
a rural neighborhood.
Shallow Creek, LLC Habitat Management Plan Page 3
In order to maintain the present water quality of the Type F stream and the Hood Canal
during work, Best Management Practices will be implemented. BMPs are defined as
physical, structural, and/or managerial practices that prevent or reduce the pollution of
water(WDOE). The following applicable BMPs shall be used to insure that water quality
is not degraded by erosion and sedimentation from rainfall at the site:
*All existing native vegetation shall be preserved except where required to be
removed for construction purposes.
*Equipment shall be cleaned and checked daily for leaks.
*Prior to commencing work, filter fabric shall be placed around the pond's two
outlets. Accumulated sediments shall be removed during the project and prior to
removing the fabric after completion of work.
The following Spill Prevention Control measures shall also be followed:
*The contractor will supply the site with a portable bathroom if an onsite bathroom is
not available for workers, so that liquid or solid waste will not become a source of
stormwater pollution.
•The contractor shall be responsible for alerting the appropriate authorities in the
event of a hazardous spill.
*The contractor shall be able to perform basic control,containment, and/or
confinement operations within the capabilities of the resources and personnel
protective equipment available. In other words, small spills, such as paint or oil,
shall be promptly and fully collected and disposed of at a suitable disposal site. In
the event of a significant spill, a fish kill, and/or if fish are observed in distress the
Washington State Department of Ecology(800.258.5990)and the Washington
State Department of Fish and Wildlife's Area Habitat Biologist,Joshua Benton
(360.602.0364),will be notified immediately.
C. Action Area
The action area is located at the pond on the project site and for approximately 450'
downstream,to where the Type F stream discharges into the Hood Canal. Besides the
proposed project location,the action area includes the area within a one mile radius of the
site in order to account for construction related noise that may affect species listed under
the Endangered Species Act by the U.S. Fish and Wildlife Service as either endangered
or threatened. The action area also includes the marine environment within a 0.5 mile
radius, in order to account for littoral drift.
III. SPECIES AND HABITAT INFORMATION
A. SPECIES INFORMATION
In the proposed project area,there are six species listed under the Endangered Species
Act by the U.S. Fish and Wildlife Service (USFWS)as either threatened, endangered, or
candidate species. The bull trout(Salvelinus confluentus), marbled murrelet
Shallow Creek, LLC Habitat Management Plan Page 4
(Brachyramphus marmoratus),northern spotted owl (Stridex occidentalis), streaked
horned lark(Eremophila alpestris strigata), and yellow-billed cuckoo(Coccyzus
americanus)are listed as threatened and critical habitat has been designated for former
three species. The proposed project area is in the bull trout's critical habitat.
In the proposed project area,there are ten species listed under the Endangered Species
Act by the National Marine Fisheries Service(NMFS) as either threatened, endangered,
or candidate species. The humpback whale (Megaptera novaeangliae), Bocaccio
(Sebastes paucispinis),and leatherback turtle (Dermochelys coriacea) are listed as
endangered,while the Puget Sound Chinook salmon(Oncorhynchus tshawytscha), Puget
Sound steelhead(Oncorhynchus mykiss), Hood Canal summer-run chum salmon
(Oncorhynchus keta), green sturgeon(Acipenser medirostris), canary rockfish(Sebastes
pinniger), yelloweye rockfish (Sebastes ruberrimus), and killer whale (Orcinus orca) are
listed as threatened. Critical habitat has been designated for the Chinook salmon, Hood
Canal summer-run chum, leatherback turtle,Puget Sound rockfish, green sturgeon, and
Puget Sound steelhead. Hood Canal is designated critical habitat for the Chinook, Hood
Canal summer-run chum salmon,and Puget Sound rockfish.
Additionally, a WDFW GIS map for the action area indicates that there are potential
forage fish spawning beaches located 0.3 west and 0.25 miles east of the site ()WDFW
2016).
C. Survey Results
A field investigation was conducted on November 3, 2016 during daylight hours, and the
proposed project area was surveyed visually on foot. The site is located on an
approximately 2.2-acre parcel that features a single-family residence, a perennial Type F
stream(fish-bearing), and a manmade pond. The property south of the pond is
moderately sloped and heavily forested, while the area between the pond and SR 106 is
relatively flat and partially cleared. Invasive, non-native knotweed was observed growing
in the vicinity of the pond.
Several existing fish passage blockages downstream from the pond(WDFW 2016)
prevent adult and possibly juvenile salmonids from accessing the unnamed Type F
stream. It is unknown whether fish may successfully access Hood Canal from the pond;
however, fish in Hood Canal are unable to access the pond, and it is expected that they
are also unable to access the daylighted stream section on the north side of SR 106.No
fish were observed in the pond.
The following native plant species were observed growing at the site: Western hemlock
(Tsuga heterophylla),Douglas-fir(Pseudotsuga menziesii), bigleaf maple (Acer
macrophyllum), Western red cedar(Thuja plicata), Red alder(alnus rubra),horsetail
(Equisetum spp.), and sword fern(Polystichum munitum).
Shallow Creek,LLC Habitat Management Plan Page 5
The following non-native, invasive plant species were observed: Himalayan blackberry
(Rubus procerus) and knotweed(Polygonum spp).
D. Existing Environmental Conditions
The environmental baseline represents the existing set of conditions,to which the effects
of the proposed action are then added. The proposed project site is located in WRIA 14
(Water Resource Inventory Area)on a parcel with a stream and a manmade pond,
adjacent to the Hood Canal. State Highway 106 accesses the site. The majority of the
shoreline along the South Shore of the Hood Canal has been developed with single-
family residences that have bulkheads and docks.
The Hood Canal is a glacial-carved fjord that runs 63 miles from its mouth at Admiralty
Inlet to Lynch Cove at Belfair. It averages 3.8 miles in width and 500 feet in depth
(Johnson et al. 1997). Several factors, including the canal's great depth,poor water
circulation, and the input of nutrients have resulted in its lowest concentrations of
dissolved oxygen in recorded history. Algae appears to be a primary culprit. Huge algae
blooms fueled by warm weather and nutrients from leaking septic tanks, dairy waste, and
fertilizer runoff, etc., eventually die then decompose, a process that consumes significant
amounts of oxygen. In October of 2003 large fish kills were reported in the Hood Canal
(USGS 2006). WDFW biologist Margie Shirato reported that a fish kill had also occurred
in 2007 near Dewatto, which is over a dozen miles northwest of the proposed project site.
WRIA 14 features an extensive network of low-elevation, low-gradient streams that are
dependant on precipitation and groundwater for flow but has no major rivers. The
majority of the fresh and marine waterbodies in WRIA 14 suffer from water quality
issues. The Hood Canal is on the WSDE's (Washington State Department of Ecology's)
2008 Water Quality 303(d)List as an impaired waterbody for the following parameters in
the vicinity of Union: dissolved oxygen and fecal coliform. Besides water quality issues
and shoreline hard-armoring, it can be assumed that the existing environmental
conditions in the area have also been degraded by organic and inorganic pollutants,
deforestation, fishing, and other anthropogenic changes that accompany urbanization.
III. Effects of the Action
A. Direct Effects
Direct effects are the immediate effects of the project on the listed species and their
habitats (FWS &NMFS 1998). The direct effect to the project site will be the dredging of
alluvial sediments from a manmade pond that acts as a sediment trap for an unnamed
Type F stream. Direct effects to the stream and the marine shoreline include: 1) The loss
of alluvial sediments that would naturally feed the stream channel and the beach.
Shallow Creek, LLC Habitat Management Plan Page 6
1) The pond is located at the upper end of the stream's natural flood plain, where the
steep terrain flattens out and the stream losses energy. The pond traps sediments
transported by the stream that were once available to feed the stream and the
beach,thus directly and adversely affecting downstream fluvial morphology and
natural beach-forming processes. Because,the stream's natural floodplain has
been compromised by anthropogenic development that precludes channel
migration,the natural fluvial process of avulsion cannot take place to offset
aggredation. An avulsion is a significant and abrupt relocation of a new channel
(WDFW 2002). A stream aggrades when more sediment is transported into the
reach than can be transported out of the reach(WDFW 2002). The unnamed
stream downstream from the proposed project site exhibits several physical
characteristics that lead to (and exacerbate) aggradation, including reduced slope
and channel confinement. Channelized streams are prone to aggradation, as they
lack the capacity for sediment storage, i.e. a floodplain or a broader migration
corridor.
Reducing the excess supply of sediments from upstream sources would be the
most effective solution, but considering the scope of such a project, it is an
unrealistic option. Increasing the stream's slope downstream from the site is also
not a viable solution,nor is removing existing infrastructure and development to
accommodate a natural floodplain. Therefore, it is necessary to dredge the pond to
alleviate or prevent downstream flooding.
The proposed project will also result in the loss of sediments that would normally
feed the marine beach near the site. However, it is expected that the beach in the
area receives sufficient sediment input from the nearby Skokomish and Tahuya
Rivers and numerous smaller streams, in addition to sediments from feeder bluffs
and other shoreline erosion.
Temporary direct effects caused by the proposed projects include: 1) Sedimentation
and/or siltation, and turbidity in the unnamed Type F stream and the Hood Canal. 2)
Noise. 3) Water pollution from incidental release of fuel, oil, or other contaminants.
1) Since the purpose of the dredging is to remove the existing deposition of
sediments in the pond,the proposed project will not contribute additional
sedimentation in excess of the amount that it will eliminate. In order to minimize
downstream turbidity and siltation, filter fabric shall be placed around the pond's
two outlets and accumulated sediments shall be removed during the project and
prior to removing the fabric after completion of work(see BMP#3). However,
increased turbidity and siltation from the dredging of the channel still may impact
salmonids in the area. Salmon are mobile, so it is possible that they will avoid the
area of disturbance and not be impacted. Salmonids have been observed to move
laterally and downstream to avoid turbidity plumes(Sigler et al. 1984, Lloyd
1987, Scannell 1988). Gregory and Northcote (1993) suggested that turbidity
could be used as a protective cover by juvenile salmon.

2) The main source of construction noise will be the operation of heavy equipment.
The project site is located in a rural commercial neighborhood that is adjacent to
a State Highway, so it is expected that the noise from heavy equipment will not
be more excessive than noise normal to the neighborhood.
3) Potential water pollution from accidental release of fuel, oil, or other
contaminants is another possible temporary direct effect. As previously
discussed, Spill Prevention Control measures and BMPs shall be implemented
during the proposed project.
B. Indirect Effects
Indirect effects are those effects that are caused by or will result from the proposed action
and are later in time, but are still reasonably certain to occur(50 CFR 402.02). Indirect
effects from the proposed project include: 1)The loss of salmonid spawning habitat in
the stream and forage fish spawning habitat on the beach.
1) Several existing fish passage blockages downstream from the pond prevent
adult and possibly juvenile salmonids from accessing the unnamed Type F
stream. In addition,the stream is predominantly tightlined(i.e. transported in a
subsurface pipe)between the pond and the Hood Canal,which further impedes
fish passage. Therefore,the loss of spawning habitat is not relevant unless the
stream is someday restored to a more natural condition.
A WDFW GIS map for the action area indicates that there are potential forage
fish spawning beaches (WDFW 2016) located 0.3 west and 0.25 miles east of
the site. As previously discussed, it is expected that the beach in the area
receives sufficient sediment input from the nearby rivers and streams, and
shoreline erosion.
C. Cumulative Effects
Cumulative effects are defined as"those effects of future state or private activities, not
involving Federal activities,that are reasonably certain to occur within the action area of
the action subject to consultation"(50 CFR 402.02). Cumulative impacts are difficult to
access. Continued growth and urbanization is likely to detrimentally impact fish and
wildlife resources. Global warming could raise the water level of Puget Sound, leaving
many waterfront properties underwater. Over-fishing may deplete stocks of salmon,
even as restoration of habitat in the watershed furthers their likelihood of survival.

D. Take Analysis
Section 9 of the ESA prohibits take of endangered or threatened species,"take"being
defined in Section 3 as to harass, harm,pursue,hunt, shoot, wound,trap, capture, or
collect listed species, or attempt to engage in any such conduct. "Harm" is further
defined as a significant habitat modification or degradation that actually kills or injures
listed species by"significantly impairing behavioral patterns such as breeding, spawning,
rearing, migrating, feeding, and sheltering"(50 CFR 222.102). "Harass" is further
defined as an intentional or negligent act which creates the likelihood of injury to wildlife
by annoying it to such an extent as to significantly disrupt normal behavior patterns
which include,but are not limited to,breeding, feeding, or sheltering(50 CFR 17.3). In
regards to the proposed project and the existing development activities, it is extremely
unlikely that any"take"will occur. The following conservation measures (some
previously discussed)will further insure the likelihood that no"take"will occur.
E. Conservation Measures
1. Previously discussed BMPs to be strictly adhered to.
2. WDFW's HPA stipulations to be strictly adhered to.
F. Determination of Effect
A determination of May affect, not likely to adversely affect is the appropriate conclusion
when effects on the species or their critical habitat are expected to be beneficial,
discountable, or insignificant After reviewing the appropriate data and survey
information, I have concluded that the proposed project will have an insignificant impact
on the previously discussed Endangered or Threatened species if the previously discussed
conservation measures are implemented. In my most honest and professional opinion,
while the proposed project may impact individual Endangered or Threatened species in
the project area, it is not likely to adversely affect or jeopardize the continued existence
of those species or their designated Critical Habitat. The determination of effect for each
of the listed species is:
1. Puget Sound chinook—No effect.
2. Puget Sound Steelhead No effect.
3. Hood Canal summer-run chum--No effect.
4. Bull trout--No effect.
