Parcel #932 200 507. Section 23, Township 30 N., Range 02 W
Jefferson County
Lat.48.076648' Long. 122.891515°
C. Project Description
The proposed project consists of constructing a new residence measuring 22' by 18' (396 ft2) (Figures 3-9). This
does not include the proposed parking area measures 9' x 22.5', nor a second parking area located off-site
measuring 10' x 22' (Figure 9 and Photo 25). Neither of these parking spaces will be improved from their current
condition. Both parking places will require a gravel strip measuring 10' x 22' between the paved road and the
actual parking area.
According to Anna Bausher (site visit- 9/22/2016), the Historic Building Line is approximately 22' landward of the
OHWM (Photo 25). The actual structure will be built 3 feet back from the Historic Building Line but in that 3 feet
will be Tx3' landing with steps.
A septic system grinder pump with associated transport lines will be installed in the proposed parking area located
between the residence and Beckett Point Road. Typical grading, leveling and filling will be undertaken. Excavation
for the foundation will be approximately two feet below grade. A Stormwater Drainage, Erosion, and Sediment
Control Plan will be submitted in conjunction with this Habitat Assessment.
According to the house plans, the elevation of the ground floor will be two feet above Base Flood Elevation (BFE)
of 9' (Figure 7).
D. Action Area
The action area should include the area within a''/2 mile radius of the project location. This area includes noise
effects from construction activities.
3. HABITAT AND SPECIES INFORMATION
A. Habitat
Two field investigations at the project site were conducted on August 24, 2016 and September 22, 2016. The
following is a description of the habitat noted in the project area:
The dominant vegetation on the property is dune grass (Leymus mollis).
There is a small cover of the following species:
Nearer to the water; American sea rocket (Cakile edentula), Puget Sound gum weed (Grindelia integrifolia) and fat
MS&A Erickson Residential Development Project- 4
hen (Atriplex patula).
Near the water and scattered through the dune grass on the lot is yellow sand -verbena (Abronia latifolia).
Between the proposed footprint and Beckett Point Road, there is a bit of wood groundsel (Senecio sylvaticus) and
plantain (Plantago lanceolata).
The Jefferson County Critical Areas map indicates that the site area is in an "Intermediate" slope stability area
(Figure 16).
According to the DOE Coastal Atlas, there is no "appreciable" net -shore drift along the shoreline (Figure 13) and
The Coastal Landform is listed as an "Accretion Shoreform" (Figure 14).
There are no documented forage fish spawning areas near the site according to Washington Department of Fish and
Wildlife (WDFW 2015, Figure 11).
(http:l/wdfw.wa.,ov/Coriservation/research/projecWmarine beach_spawn inWindex.htntl).
B. Species
Figures 17-18 show the Priority Habitats and Species present in the area (WDFW 2015. Priority Habitats and
Species. Available at: http://wdfw.wa.gov/mapping/phs/. Olympia, Washington). The project site area is adjacent to
"Aquatic Habitat".
Federally Listed Species That May be Present in the Area:
In the project vicinity, there are two salmon species, Hood Canal summer -run chum (Oncorhynchus keta) and
Puget Sound Chinook (Oncorhynchus tshawytscha), listed under the Endangered Species Act as threatened species
according to the National Marine Fisheries Service (NMFS)(Federal Register, Vol. 64, Nos. 56 and 57).
NMFS also listed the Puget Sound steelhead (Oncorhynchus mykiss) as a threatened species under the ESA
(Federal Register / Vol. 72, No. 91 / Friday, May 11, 2007 / Rules and Regulations).
Bull trout (Salvelinus confluentus) were listed as threatened by the United States Fish and Wildlife Service
(USFWS) in October of 1999.
On April, 23, 2009, NOAA listed the distinct population segments (DPSs) of yelloweye and canary rockfish as
threatened species under the Endangered Species Act (ESA) and proposed that the Georgia Basin DPS of bocaccio
be listed as endangered. According to NOAA (Federal Register / Vol. 75, No. 81 /April 28, 2010 / Rules and
Regulations), the area for the proposed listed rockfish includes all of Puget Sound south of Admiralty Inlet. The
Georgia Basin refers to all of Puget Sound, including the area around the San Juan Islands, and the Strait of
Georgia north to the mouth of the Campbell River in British Columbia. The western boundary of the Georgia Basin
runs from east of Port Angeles to Victoria in the Strait of Juan de Fuca.
Critical habitat was designated for these three DPSs (Federal Resister / Vol 79, No 219 / Thursday, November 13,
2014 / Final Rule). The site shoreline is in the critical habitat shoreline area for juvenile canary and bocaccio
rockfish. However, NMFS is proposing to remove canary rockfish from the federal list of threatened and
Endangered Species (07/06/2016).
On September 2, 2005, NMFS issued the final rule designating critical habitat for 12 Evolutionarily Significant
Units (ESUs) of West Coast salmon, including the Puget Sound Chinook Salmon ESU and the Hood Canal
Summer -run Chum ESU. The project site is in the designated area for the Puget Sound Chinook and Hood Canal
Summer -run ESUs (Federal Register / Vol 70, No. 170 / Friday, September 2, 2005 / Rules and Regulations).
Critical habitat has been designated for Pacific steelhead (Federal Register / February 24, 2016 / Final Rule).
On November 15, 2005 NMFS listed the Southern Resident killer whale (Orcinus orca) as endangered under ESA
(Federal Register / Vol. 70, No. 222 / November 18, 2005 / Rules and Regulations). NOAA Fisheries has
designated critical habitat for killer whales (Federal Register / Vol. 71, No. 229 / November 29, 2006 / Final
Rule). "Critical habitat includes waters deeper than 20' relative to a contiguous shoreline delimited by the line of
extreme high water." Therefore, the project site is not in an area designated as critical habitat for the Southern
Resident killer whales.
MS&A Erickson Residential Development Project* 5
The project site is on a shoreline designated as critical habitat for Coastal -Puget Sound bull trout (Federal Register
/ Vol. 75, No. 200 / October 18, 2010 / Rules and Regulations).
Marbled murrelets (Brachyramphus marmoratus) have also been listed as threatened by the USFWS since 1992.
There is no murrelet critical habitat near the site (Federal Register / Vol. 61, No. 102/ 1996).
4. EFFECTS ANALYSIS OF PROPOSED PROJECT
The status of each of the listed species in the action area has been provided. The project has been described and the
action area defined. When reviewing all the data, the direct and indirect effects of the project on the listed species
and their critical habitat should be considered.
A. Direct Effects: When considering the direct effects of the proposed project, one must determine if the proposed
project will immediately reduce or destroy the listed species and/or their habitat. The potential, direct impacts
caused by the construction process include the following:
1. There may be siltation caused by soil erosion and runoff during construction and land preparation. Any siltation
has the potential to impact migrating salmonids in the nearshore area.
Siltation in the nearshore during construction will be avoided by the implementation of the Best Management
Practices (BMP) outlined in the Stormwater Drainage, Erosion, and Sediment Control Plan submitted for this
project.
2. There will be some construction noise associated the project, which may have temporary impacts on wildlife
Potential impacts to wildlife due to construction will be minimal. There may be some disturbance of
nesting/perching for song birds. In addition, construction of the single family residence is removed from the
nearshore, so movement of fish should not be interrupted.
3. Decreased number of native or non-native plants: The proposed house footprint will displace some dune grass.
This impact to habitat function will be rectified by the planting of a variety of native vegetation at the project site
and at the second parking area near the lagoon. In addition, the area around the perimeter of the house footprint that
is disturbed by construction will be planted with dune grass and yellow sand -verbena. See the details in Attachment
1.
The project site is adjacent to an area identified by FEMA as a protected area. Because of this, the impacts on the
following issues need to be addressed:
a. Does the project involve the removal of native vegetation? Yes, see above.
b. Does the project include channel straightening? No.
c. Does the project result in habitat isolation? No.
d. Does the project include bank armoring? No.
e. Does the project reduce flood storage capacity? No.
f. Does the project result in degradation of water quality? No
g. Will there be construction effects (noise or turbidity)? Yes, see above.
h. Will there be impacts to floodplain refugia for ESA -listed fish. No impacts are expected as a result of this
project.
i. Will the project impact spawning substrate. No impacts are expected to spawning substrate.
j. Does the project impact flood volumes and flood velocities. No: The foundation will be designed so that it is
4.25' above grade and engineered with flow through and venting.
B. Indirect Effects: When considering the indirect effects of the proposed project on the listed species and their
habitat, one must determine the effects that might occur later in time, after completion of the project.
The impacts caused by the increase in impervious surface area will be avoided by the Best Management Practices
MS&A
Erickson Residential Development Project- 6
(BMP) outlined in the Stormwater Drainage, Erosion, and Sediment Control Plan submitted for this project.
C. Interrelated/Interdependent Effects:
Completion of this project will not promote fixture construction or other activities that would not otherwise occur
without its completion. Therefore, no additional interrelated or interdependent actions that could affect species
regulated under ESA will occur because of this project.
D. Take Analysis:
The ESA (Section 3) defines "take" as to "harass, harm, pursue, hunt, shoot, wound, trap, capture, collect or
attempt to engage in any such conduct." The USFWS further defines "harm" as "significant habitat modification or
degradation that results in death or injury to listed species by significantly impairing behavioral patterns such as
breeding, feeding, or sheltering." It is likely that no "take" will result from this project.
E. Determination of Effect:
After reviewing the appropriate data and surveys, the determination of effect is:
1. Puget Sound chinook - "May affect, not likely to adversely affect"
2. Hood Canal Summer -run Chum — "May affect, not likely to adversely affect"
3. Bocaccio, yelloweye and canary rockfish - "May effect, not likely to adversely affect"
4. Bull trout - "May affect, not likely to adversely affect"
5. Puget Sound steelhead - "May affect, not likely to adversely affect"
6. Marbled murrelet - "May affect, not likely to adversely affect"
5. Protective Measures
A. Siltation protection:
Stormwater Drainage, Erosion, and Sediment Control Plan has been developed to minimize any post construction
erosion resulting from the reduction in impervious surface area.
B. Displacement of Dunegrass
Various species of native vegetation will be planted at the site and also at the second parking sited to minimize
impacts due to the loss dune grass. The variation in species will add diversity to the dunegrass that is already
present at the site. (See the Planting Plan below — Attachment 1).

Attachment 1. Planting Plan
A. Introduction
On 24 August, 2016 the site was visited by Marine Surveys & Assessments to determine the feasibility of one
building envelope on parcel # 932200507 Lot 7, West Beach, Beckett Point Fisherman's Club, located on
Discovery Bay.
B. Site Vegetation
The vegetation on this property is primarily American Dune Grass (Leymus mollis) (mowed a regular basis). Other
plants noted on the site include: American sea rocket (Cakile edentula), Puget Sound gum weed (Grindelia
integrifolia), fat hen (A triplex patula) and Silver Burweed (Ambrosia Chamissonis) growing between the historic
building line and the mean higher high water. Yellow sand -verbena (Abronia latifolia) was found growing both on
the waterward and landward sides of the historic building line scattered through the dunegrass.
B. Planting Plan
As the proposed structure will be built on a shoreline of statewide significance and will impact critical habitats,
native plants will be installed in four areas (see the planting Plan Map below) to compensate for these impacts:
1) On the parcel along the north and south property lines,
2) Between the historic building line and the Ordinary High Water Mark (OHWM) which lies along -the driftwood
covered edge of the beach and
3) On the western edge of parking spot #1.
4) Around the perimeter of the house footprint that is disturbed by construction.
Plant Specifications
The planting plan areas can be seen in the figure below. The plants selected for this site are all native plants that
can tolerate salt spray from the marine environment. They were selected to improve the overall value of the
functions in this critical area buffer. Soil stability, nutrient input, and wildlife habitat were all important factors.
Following is a table showing the plant species and numbers for the planting area. Plants will be selected from a
regional native plant nursery. Gallon species will be purchase from a native plant nursery. Plants will have well-
developed roots and sturdy stems, with an appropriate root -to shoot ratio and will be planted as soon as possible
after purchase. All stock must be kept cool and moist prior to installation. Unacceptable plant materials will not
be planted.

Plants should be installed in late fall or early spring following the construction work. During these times plant are
semi -dormant and soils are easier to work. Plants will be laid out by hand generally following the spacing specified
on the planting plan map. The shrubs will be installed by digging a one to two foot hole, loosening the soil, placing
the plant in the ground after loosening soil around the root ball. The hole must be deep enough to ensure the roots
are straight, but not so deep as to bury plants too far above the root collar. Once the plant is in place, the hole will
be backfilled and tamped lightly. Mulch should be applied 3" deep around plants, being careful not to touch the
stem of the plant. Plugs of the American dunegrass and yellow sand -verbena will be planted similarly using hole
sizes appropriate to the size of plug being planted. No extraordinary measures are proposed at this time to protect
installed plants other than mulching, weeding and watering. Substitutions might be necessary for species or
individuals that cannot be found at local nurseries. All plant substitutions will be approved by the project biologist
prior to installation to ensure their suitability for the site.
B. Monitoring Plan and Performance Standards
An as -built drawing and report will be submitted to Jefferson County DCD as documentation of the
implementation of the approved planting plan within one month of installation. Once approved, the monitoring
proposal is to maintain and monitor the survival of the native plants installed as well as removal of the invasive
plants for five years.
The plan will include vegetation description and photo documentation from established photo stations. A
panoramic photo of the entire mitigation site will also be provided. Monitoring will take place over a period of five
years at the end of the growing season (late August or early September) of each monitoring year. The performance
standards will be monitored by measuring plots in zones within the planting area that will be established and
mapped after planting occurs, on the as -built plan. There will be photo points for each plot and they will be
referenced on the as -built plan. Each year the photo points that are established at each site will be used for
comparison. Photos will be taken at all points for all years as visual documentation of the performance standards
progress, or lack of.
In addition to photos at designated points, photos documentation must include a panoramic view of the entire
planting area. Submitted photos must be formatted on standard 8 %2" by 11" paper, dated with the date the photo
was taken, and clearly labeled with the direction from which the photo was taken. The photo location points must
be identified on an appropriate drawing.
Collected data and photos will be compiled into an annual Wetland Planting report each year and submitted to the
Jefferson County DCD by December of each monitoring year for five years. Each annual monitoring report shall
include written and photographic documentation on plant mortality and replanting efforts and must document
whether the performance standards are being met. Monitoring results will determine whether or not contingency
measures will be needed.
Performance Standards #1 and #2
Year 1: Achieve 100% survival success of planted natives into mitigation areas.
Year 2: Achieve 100% survival success at end of second year into mitigation areas.
Year 3: Achieve 80% survival success at end of third year into mitigation areas.
Year 4: Achieve 80% survival success at end of fourth year into mitigation areas.
Year 5: Achieve 80% survival success at end of into mitigation areas.

Performance Standard #3
Year 1: Achieve 100% removal of targeting invasive species from mitigation areas.
Year 2: Achieve 100% removal of targeting invasive species from mitigation areas.
Year 3: Achieve 100% removal of targeting invasive species from mitigation areas.
Year 4: Achieve 100% removal of targeting invasive species from mitigation areas.
Year 5: Achieve 100% removal of targeting invasive species from mitigation areas.
MAINTENANCE AND CONTINGENCY
Maintenance shall occur at least twice during the growing season to ensure the survival of all native species within
the mitigation area, including volunteer natives. Watering by hand may be necessary during year one until natural
underlying hydrology is re-established. Water requirements will depend on the timing of planting with the seasons,
weather conditions, and underlying hydrology. Once plants are established, extra watering is not anticipated to be
necessary. Removal of aggressive invasive vegetation will be necessary within all sections that are being monitored
for survival and coverage, until either native plantings can naturally suppress competition or five-year monitoring
period has passed.
If the required survival rate is not met by the end of any monitoring year, plants lost to mortality will be replaced to
achieve the percentage cover performance standard described above. Prior to replacement, an appropriate
assessment will be performed to determine if the survival was affected by species/site selection, animal damage, or
some other factor. Subsequent contingency actions must be designed to respond directly to the stressor(s), which
are increasing mortality of planted native species. If a particular species is shown not to endure site conditions then
another, more appropriate species will be selected. If excessive damage is observed, protective measures will be
introduced. Monitoring years may be added if significant re -planting becomes necessary.
Monitoring on an annual basis for five years will occur with photographs to determine the survival rate of the
transplanted area. If 100% success is achieved before reaching the five-year mark, monitoring will continue
without extra replanting efforts. Within the five-year time period, transplanting will occur on an annual basis to
replace any plants that are lost until 100% success is achieved.
