Attachment 1. Buffer Enhancement Planting Plan
A. Mitigation Plan
Mitigation is required for this site as the proposed structures will be built on a shoreline of statewide
significance and will impact critical habitat. Approximately 1,532 sq. ft. will be planted with native
species (Figure 1). Once the plants are established, there will be an improvement to the overall value of
the functions in this portion of the critical area buffer. Soil stability, nutrient input, wildlife habitat and
site conditions were all considered when choosing the plants for this site. Following is a table showing
the plant species and numbers for the planting areas. Plants will be selected from a regional native plant
nursery.

Plants should be installed in late fall or early spring following the construction work. During these times
plants 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 (Figure 1). Soil may be amended as needed. The plants
will be installed by digging a one to two foot hole, loosening the soil, placing plant in ground after
loosening soil around root ball. The hole must be deep enough to ensure that 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 stem of
plant. No extraordinary measures are proposed at this time to protect the installed plants other than
mulching, weeding and watering. Substitutions might be necessary for species or individuals that cannot
MS&A Cline Residential Development Project- 42
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. Performance Standards
Performance standards are measurable criteria for determining if the goals and objectives of the
mitigation project are being achieved. If the proposed benclunarks are not achieved by comparing the
surveys to the mitigation goals, then contingency plans will need to be implemented.
Performance Standard # I (survival rate): Immediately after planting, all plants will be counted and
documented. At the end of each growing season (late Aug- early Sept) plots will be visited and a count of
surviving plants will be doclnnented. The percent survival for the plots will be calculated by dividing the
total number of plants after planting by the total number of surviving plants at the end of the season. Photo
stations for each planting site will be determined and a photograph of each transplant location will be taken
on an annual basis. Individual plants that die must be replaced with native species in order to meet the
survival performance standards.
Performance Standard # 2 (percent cover): The percent cover standard will be monitored by
looking at each monitoring unit of the enhanced areas from above and estimating the area covered
by the individual species. The percent cover within an area can be quantified as a total greater
than 100% because plants (in tree, high/low shrub and herbaceous layers) overlap in cover.
C. Monitoring Plan
An as -built drawing and report will be submitted as documentation of the implementation of the approved
planting plan within one month of installation.. 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. Photos should be taken June - August, during the growing season. 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, photo documentation must include a panoramic view of the entire planting area.
Submitted photos must be formatted on standard 8 1/2 " by 1 l " 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
Riparian Planting report each year and submitted by November 30 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 & 2
Year 1: Achieve 100% survival success of replanted 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 fifth year into mitigation areas
Mb&A Cline Residential Development Project- 43
D. 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 or sprinkler may be
necessary during year number one until the plants are established. Water requirements will depend on the
timing of planting with the seasons and weather conditions. Once plants are established, extra watering
may not be necessary. Hand weeding will be necessary around all plants that are being monitored for
survival and coverage. 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.

B. Project Location
1196 Beckett Point Rd. (lots #6 and 7), Port Townsend, WA 98368
Parcel #932 200 707, Jefferson County
Section 23, Township 30 N., Range 02 W.
Lat. 48004'39.84"N, Long. 122°53'05.85"W
C. Project Description
The proposed project consists of constructing a new residence measuring approximately 45' by 22' (900 ftz) and
parking area measures 8' x 15' (120 W) (Figures 3-10) on each of the two lots, #6 and 7. Additionally each lot will
also have 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
(Figures 11-17).
According to Jefferson County the Historic Building Line is approximately 22' landward of the OHWM or the
wooden bulkhead in this scenario. The actual structure will be built between 16.5 to 19.1 feet back from the
wooden bulkhead and thus be between 5.5 and 2.9 feet waterward of the Historic Building Line.
According to the house plans, the elevation of the ground floor will be one feet above Base Flood Elevation (BFE)
of 9' (Figures 8-10).
D. Action Area
The action area should include the area within a %z mile radius of the project location. This area includes noise
effects from construction activities.
3. HABITAT AND SPECIES INFORMATION
A. Habitat
One field investigation at the project site was conducted on January 6h, 2017. The following is a description of the
habitat noted in the project area (Figures 28-35):
The dominant vegetation on the property is unidentified grass (most likely lawn species).
There is small cover of the following species: American sea rocket (Cakile edentula) and fat hen (Atriplex patula)
growing nearest the water, interspersed with trace amounts of dune grass (Leymus mollis). Scattered through the
trace dune grass on the lot is yellow sand -verbena (Abronia latifolia). See Figures 36 to 40 for site vegetation.
Note since the site visit was done in the winter, some the quantities and identities of the plants above may be
inaccurate.
MS&A Cline Residential Development Project• 4
According to WDOE, there are patchy eelgrass beds in the subtidal area of the shoreline (Figure 20). The Jefferson
County Critical Areas map indicates that the site area is in an "Intermediate" slope stability area (Figure 25).
According to the DOE Coastal Atlas, this location is at the end of a drift cell that is from east to west or from right
to left when facing the shore from the water (Figure 21) and The Coastal Landform is listed as an "Modified and
Accretion Shoreform" (Figures 22- 23).
There is Herring spawning just offshore of the project site according to Washington Department of Fish and
Wildlife (WDFW 2017, Figure 19).
(http_//wdfw.wa.govlconseivation./research/12rojects/marine beach spawning/index.htmi).
B. Species
Figures 26-27 show the Priority Habitats and Species present in the area (WDFW 2017. 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.
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).
MS&A Cline Residential Development Project- 5
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, followed by means to address them, 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
(BMP) outlined in the Stormwater Drainage, Erosion, and Sediment Control Plan submitted for this project.
MS&A Cline Residential Development Project 6
C. Interrelated/Interdependent Effects:
Completion of this project will not promote future 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"
S. Puget Sound steelhead - "May affect, not likely to adversely affect"
6. Marbled murrelet - "May affect, not likely to adversely affect"
F. No Net Loss Analysis
All measures have been taken to avoid and minimize potential impacts resulting from the proposed project. A
mitigation plan has been developed for this property to enhance the buffer and retain ecological function or values.
In consideration of the unlikely impact to ESA species as well as the proposed mitigation suggested below, we
determine that no -net -loss of ecological function will result from this project's unavoidable impacts due to its'
water dependent use. Additionally we believe that this project reflects the goal of the Shoreline Master Program by
balancing access to the environment with the protection of that environment.
MS&A Cline Residential Development Project• 7
5. Protective Measures
A. Mitigation Planting Plan
A buffer enhancement planting plan has been developed as mitigation for this project. This plan was designed to
increase the amount of native plant species in the shoreline buffer on the property as well as to retain and ensure no
net -loss of ecological functions and values of the shoreline. Please find the plan and map in Attachment 1 below.
B. Siltation Management: Several methods are suggested to prevent siltation in the Washington State Department
of Ecology's STORM WATER MANAGEMENT MANUAL FOR THE PUGET SOUND BASIN, often termed
"the Technical Manual" (WDOE 2012).
The following precautions for siltation prevention during construction processes are
suggested in Volume II "Construction Stormwater Pollution Prevention" in the
Stormwater Management Manual for Western Washington. These Best Management
Practices (BMPs) are as follows:
• BMP C101: Preserving Natural Vegetation
■ BMP C102: Buffer Zones
■ BMP C103: High Visibility Fence
• BMP C105: Stabilized Construction Entrance / Exit
■ BMP C106: Wheel Wash
• BMP C107: Construction Road/Parking Area Stabilization
• BMP C120: Temporary and Permanent Seeding
• BMP C121: Mulching
• BMP C122: Nets and Blankets
• BMP C123: Plastic Covering
• BMP C124: Sodding
• BMP C125: Topsoiling / Composting
• BMP C126: Polyacrylamide (PAM) for Soil Erosion Protection
• BMP C130: Surface Roughening
• BMP C131: Gradient Terraces
■ BMP C140: Dust Control
• BMP C150: Materials on Hand
■ BMP C151: Concrete Handling
• BMP C152: Sawcutting and Surfacing Pollution Prevention
■ BMP C153: Material Delivery, Storage and Containment
• BMP C154: Concrete Washout Area
