FINDINGS OF FACT
The subject property is located at 2876 SW 300`" Pi within the SMP Shoreline Residential overlay.
The existing use of the property is single-family residential.
2. The subject property contains an existing rock course bulkhead and stairway along a portion of the
property's shoreline measuring approximately 40 linear feet along the OHWM. The remaining
shoreline is unarmored with a vegetated bank approximately seven feet in height.
3. The OHWM elevation along the unarmored shoreline frontage is 13 feet.
4. Geotechnical assessments of the subject property's existing shoreline modification indicate the
bulkhead's terminus near the center of the property is in danger of failure due to erosion via wave
action tunneling behind the bulkhead and scouring of the retained soils.
5. Applicant proposes maintenance and repair of the existing bulkhead via return -type wall that will be
constructed perpendicular to the existing bulkhead and provide a cap that will resist waves scouring
behind the existing bulkhead.
6. Geotechnical and shoreline assessments of the unannored portion of shoreline indicate the top of
bank consists of fully vegetated fill material and native outwash soils that are sloughing onto the
beach. The underlying toe of the bank is hard glacially consolidated soils that have remained in place.
7. Applicant proposes to install a retaining wall that will prevent top of bank sloughing. The wall will be
constructed along the bank between the 16-foot and 21-foot elevations. The wall will extend
approximately 28 linear feet along the shoreline and return landward approximately 9 feet. The toe of
the bank will remain in place unarmored.
8. Project applicant anticipates 45 cubic yards of soil excavation and 67 cubic yards of imported rock,
drain rock, and top soil for wall repair and proposed new wall construction.
9. The subject property has been identified and recorded by the Department of Archeology and Historic
Preservation as site 45KI732. Cultural resource items on the site include pre -contact shell midden and
fire modified rocks.

CONCLUSIONS
1. Capping the existing bulkhead as shown in the proposed site plan is normal maintenance of an
existing structure to prevent a decline from a lawfully established condition and is therefore exempt
from obtaining a shoreline substantial development permit pursuant to Washington Administrative
Code (WAC) 173-27-040(2)(b).
2. The proposed retaining wall on the site plan is landward of the OHWM with a purpose of retaining
sloughing materials from the top of bank. The existing toe along the shoreline will remain intact and
unannored. Total grading to accommodate the proposed retaining wall is less than 250 cubic yards
and thereby qualifies the proposal as a normal appurtenance connected to the use and enjoyment of a
single-family residence. Therefore, the retaining wall is exempt from obtaining a shoreline substantial'
development permit pursuant to WAC 173-27-040(2)(g).
3. As conditioned, this shoreline exemption issued under FWRC 15.05.130 complies with the shoreline
guidelines and the goals, policies, and applicable provisions of the Federal Way Shoreline Master
Program and Washington State Shoreline Management Act.
As conditioned, no site work associated with the installation of the retaining wall will occur
waterward of the OHWM and therefore pursuant to State Environmental Policy Act (SEPA) Rules
WAC 197-11-800(2)(e), the proposed minor new construction is categorically exempt from an
environmental threshold determination. Site work associated with the normal maintenance of the
existing bulkhead is also categorically exempt from an environmental threshold determination
pursuant to WAC 197-11-800(3).
CLOSING
This Substantial Development Permit Exemption is not authorization to begin construction of the
improvements. Construction may begin when the associated building permit is issued and all other
applicable agency approvals have been issued. You may contact Matt Herrera, Senior Planner, at 253-
835-2638 or matt.herrera@cityoffederalway.com if you have any questions regarding this letter.

File No. 21468-001-01
INTRODUCTION
The purpose of this revised letter report is to present GeoEngineers, Inc.'s (GeoEngineers) observations
and assessment of environmental conditions associated with the Shimer Property Retaining Wall project
(project). We also evaluated the project's potential impacts to the environment at the site. Recently, the
owners observed unstable areas in the upland portion of their property near the shoreline. It is our
understanding that the owners are seeking authorization from the City of Federal Way (City) to construct a
new retaining wall. The purpose of the retaining wall is to retain these unstable upland slopes and to protect
known shell midden deposits.
The Shimer property is located at 2876 SW 300th Place in Federal Way, Washington on tax
parcel 416660-0185. The Shimer property is mapped on Sheet 1 of the project design included
as Appendix A. The parcel is located on Puget Sound and contains approximately 60 linear feet of
shoreline. An existing rock bulkhead protects approximately 35 linear feet of the eastern portion of
the shoreline from tidal and wave action. It is our understanding that the owners constructed the existing
rock bulkhead in 2006 and it protects a known culturally sensitive shell midden located immediately
landward of the existing rock bulkhead. The remaining western portion, approximately 25 linear feet, of the
shoreline is unprotected. Since 2006, the end of the existing bulkhead has been damaged by wave action.
Also, unstable upland slopes have experienced sliding.
The owners contracted Coast and Harbor Engineering of Edmonds, Washington to complete a design for an
upland wall to retain unstable slopes while setting back from the ordinary high water mark (OHWM) to allow
for natural shoreline beach conditions. The owners previously sought approval for a bulkhead, which was
denied. Accordingly, Coast and Harbor Engineering developed the proposed retaining .wall concept to
accomplish this goal.

PROJECT DESCRIPTION
The owners propose to construct an approximately 25-foot long rock retaining wall on the upland near the
shoreline and perform minor repairs to the existing rock bulkhead. The project design is included as
Appendix A to this letter. The rock retaining wall will tie into the existing rock bulkhead and the new wall will
be constructed landward of OHWM.
The purpose of the project is to retain unstable upland slopes. The upland slopes are prone to slides and
resulting in a loss of soil. Also, the existing rock bulkhead protects a culturally sensitive, shell midden. The
proposed bulkhead repair and retaining wall are intended to protect the shell midden. Without the repair
and tie in to the retaining wall, the bulkhead will continue to experience damage.
The proposed retaining wall can feasibly be constructed from a barge stationed on the beach or from the
upland. The construction method will be determined based on bids received from potential contractors.
However, working from above will likely reduce the risk of disturbing the hard native soil located below and
waterward of the wall. Regardless of the construction method, footings will be excavated using a small to
medium sized excavator. Excavation will be the minimum required for wall footings and existing
consolidated material will remain. The retaining wall will be constructed with approximately 20 cubic yards
of rock. The top of the proposed retaining wall will be constructed at approximate Elevation 21 feet mean
lower low water (MLLW) and will include a subsurface drain to alleviate hydrostatic pressure behind the
wall. The retaining wall will be backfilled with 1-inch drain rock. Material that is located waterward of the
face of the new retaining wall will be excavated and removed from the site.
The upland retaining wall creates the opportunity for passive restoration of new beach habitat waterward
of the wall. Existing consolidated material will remain, but unconsolidated sliding material will be removed,
allowing for natural beach condition. Upon completion of the new retaining wall, the contractor will restore
and enhance the disturbed upland area. The contractor will install native and appropriate ornamental shrub
species in the areas disturbed by construction.
ROCK WALL DESIGN AND CONSTRUCTION CONSIDERATIONS
We have reviewed the general plans prepared by Coast & Harbor Engineering for the rock walls that will be
used to support the upper portion of the slope. We also understand the rock walls will be supported by the
hard native soil, and be set back and above the beach level (see attachments to this letter). In our opinion,
the upper portion of the slope at the site may be faced with rock walls, provided certain limitations are
understood as discussed below. It is important to realize that these rock walls do not provide the same
level of soil retention as a structural wall, and are therefore not intended as retaining structures. The
primary purpose of this type of rock wall is to protect the upper portion of the slope face from erosion and
raveling, while providing limited soil retention and support. Rock walls are an alternative wall type which
are usually less costly than structural walls but involve more risk of failure. There is always some risk of
rock wall movement or failure even when the foundation soil and retained material are satisfactory and the
rock wall materials and construction are satisfactory. It is also important to understand that the hard native
soils located below and waterward of the bottom of the wall will erode slowly under the expected wave and
storm actions. Future wall repairs may be needed to reduce the risk of slope failure.
Properly constructed rock walls are typically used to face slopes up to about 6 feet in height when
unreinforced, and to heights in excess of 8 feet in reinforced fills and dense native soils. With the soil
conditions encountered at the site, we expect these walls will primarily be facing dense native soil
conditions, except for the upper couple of feet which may be fill or weathered soil.
GEOENGINEERS�
File No. 21468-001-01
Revised Project Description and Assessment August 3, 2015 Page 3
An experienced and skillful craftsman in rock wall construction should install these walls. The lowest course
of rock should be embedded at least 12 inches below the lowest adjacent ground surface and must bear
on firm, hard undisturbed soils. Care must be taken during excavation to avoid disturbance of the hard
native soil located waterward of bottom of the wall. It is likely that working from above will reduce the risk
of disturbing the hard native soil located waterward of the bottom of the wall. The rock wall face should be
constructed with a batter of about 1H:4V (horizontal to vertical). Rock courses should be gradational in size
from top to bottom with the largest rocks of uniform size being placed for the lowest course. We recommend
that the lowest course consist of four or five -man rock per Washington State Department of Transportation
(WSDOT) Standard Specifications Section 9-13.7. The contact between each rock course should slope
downward to the back side of the rock wall. Each course of rocks should be seated tightly and evenly on
the course beneath so each rock rests on two rocks below. Rock selection and placement should limit voids
in the exposed face of the wall and allow no open voids of over 6 inches across in any direction. After
seating each course of rock, all voids between the rocks should be chinked on the back side with quarry
spalls to eliminate passage of backfill material.
The rock wall should include a drainage zone behind the wall. This zone may consist of washed drain rock
fully enclosed in a nonwoven geotextile to prevent it from raveling from behind the wall. Backfill between
the rock wall drainage zone and the adjacent excavation cut slope may consist of imported sand and gravel
compacted to a firm and unyielding condition.
SHORELINE ASSESSMENT
A GeoEngineers biologist and geotechnical engineer completed a shoreline assessment at the site on
May 28, 2014. The GeoEngineers biologist also performed site visits on March 27, 2014 and
December 18, 2014. In attendance at the December 2014 site visit were representatives from the City and
Washington State Department of Ecology (Ecology).
Geologic Conditions
Prior to our shoreline assessment, we reviewed the Washington Department of Natural Resources (DNR)
Interactive Geologic Map online and the US Geologic Survey (USGS) "Geologic Map of the Poverty Bay
Quadrangle" dated 2004 that identified the surficial soils at the site as Fraser age glacial outwash. Glacial
drift of the Fraser glaciation is also identified in the area as is older glacially consolidated soil along the
shoreline to the north of the site. The outwash deposits mapped at the site are generally mixtures of silt,
sand and gravel that have been deposited by streams during and following the last glacial advance.
Whereas the underlying drift can include glacially consolidated silt, sand and gravel that is dense and
relatively erosion resistant, the older glacial consolidated deposits identified north of the site are
predominantly fine grained silt and clay. In our opinion, the soils exposed at the beach level of the Shimer
property and discussed below are the older glacially consolidated fine grained soils (Figure 2).
We scheduled our shoreline assessment during a low tide event. The tidal elevation during our site
assessment was approximately -1.1 feet (MLLW). Immediately west of the owners' existing rock bulkhead,
we observed an approximately 8-foot high bank that extends into the City right-of-way (ROW) located
immediately west of the Shimer parcel. We observed a failure of the bank and the failed material ended up
on the beach. Some of this sloughed material has been subsequently eroded and transported via wave and
tidal processes. The unprotected bank on the Shimer property is vegetated with shrub species which
overhangs the beach. According to the owners, this bank failed in 2013 and is isolated to their property

and does not encroach into the City ROW. It appears that the fully vegetated bank failed episodically and
this failure resulted in a recession of the top of the bank of approximately 7 feet.
According to the owner, additional material from the bank sloughed on to the beach following a December
2014 storm.
Photo 1: Shimershorelinefacing southeast.
The City constructed a rock -lined stormwater outfall within the ROW west of the Shimer parcel. In general,
the City ROW is vegetated in noxious and invasive knotweed (Polygonum spp.) and willows (Salix spp.). A
primitive public access trail to the beach is located in the City ROW. At the toe of the bank, within the City
ROW we observed a near vertical, relatively resistant native soil layer that appears to be glacially
consolidated fine grained deposit with some gravel. This layer is approximately 3 to 4 feet thick above the
elevation of the beach and is overlain by unconsolidated soil that appears to be fill material or native
outwash soils that have been mapped at the site, extending to the top of the bank.
Based on our observations at the site, it appears that the harder underlying glacially consolidated soil is
relatively resistant to wave and tidal action. However, the overlying softer soils and unconsolidated fill and
outwash soil is subject to sloughing. Because the failed bank is fully vegetated, it appears that the
vegetation is not effective in preventing the undermining of the erodible material in the bank.
In our opinion, the unconsolidated outwash and fill material in the upper portion of the bank will continue
to episodically fail. As illustrated in the Figure 2, if no action is taken to arrest on -going slope failure, we
anticipate that the slope will, minimally, experience landward migration to a 1.5H:1V (horizontal to vertical)
slope from the top of the glacially consolidated soil. By factoring in groundwater saturation that appears to
be perched on this relatively impervious material, we expect that the slope will continue to slump to 2H:1V
slope with a concave -shaped profile. Slope failure of this nature may result in the landward migration of the
top of the slope approximately 10-15 feet from the pre-2013 top of slope location. The underlying glacially
consolidated soil is expected to erode but at a much slower rate.

Habitat Conditions
During the site visits, the GeoEngineers biologist documented intertidal habitat conditions of the beach
waterward of the Shimer property and the upland shoreline environment. In general, the beach consists of
coarse gravel and cobble. This beach substrate is typical of high energy (tidal and wave) Puget Sound
intertidal habitats. These intertidal habitats are primarily used by forage fish, crabs and numerous small
invertebrates. Shorebirds, herons and raptors also forage for prey in these shallow water habitats.
At the upper beach, within the City ROW, we observed a small (approximately 20 square foot) area of beach
consisting of gravel and sand with many shell fragments. This beach substrate may be used as spawning
habitat for surf smelt (Hypomesus pretiosus). Surf smelt spawning in this area of Puget Sound is expected
to occur in the fall and winter. Because of the lack of fine beach substrate (small gravel and sand), we do
not expect that Pacific sand lance (Ammodytes hexapterus) utilize the beach on the Shimer parcel for
spawning. However, Pacific herring (Clupea pallasii) spawning habitat exists within the lower beach in the
areas vegetated by eelgrass (Zostera spp.) which we observed approximately 200 feet waterward of the
shoreline. The Washington Department of Fish and Wildlife (WDFW, 2014a) does not document the
presence of forage fish spawning near the site.
Pacific salmon, including federally protected species are present in the intertidal areas of Puget Sound.
However in is unlikely that they extensively utilize the upper beach and would only be in the proximity of the
shoreline during high tide events.
Residential development substantially limits nearshore habitat conditions along the shoreline. The
unprotected bank on the Shimer parcel and the City ROW are the only unprotected portions of the shoreline
that we observed in the immediate vicinity. The shorelines of the adjacent parcels have been armored,
primarily with concrete bulkheads, and much of the shoreline vegetation has been removed. Because of
the presence of overhanging vegetation on the Shimer parcel and City ROW, nearshore habitat conditions
are somewhat less degraded than the shoreline habitat in the vicinity of the site. Currently, the vegetation
on the Shimer shoreline consists of shrubs including, snowberry (Symphoricarpos albus), Nootka rose
(Rosa nutkana) and Himalayan blackberry (Rubus armeniacus).
At the time of our site visit, we observe no accumulation of woody material on the beach. It appears that
the wave and tidal energy at the site, the presence of shoreline armoring in the vicinity of the site and the
dramatic shift in the natural beach profile (Figure 1) on the Shimer parcel preclude the accumulation of
coarse woody debris along the shoreline.
IMPACT ANALYSIS
Because the proposed retaining wall will be constructed landward of OHWM, we expect that there will be
no negative impacts to the aquatic habitat of Puget Sound.
The project will result in minor temporary disturbance to the upland area of shoreline during construction.
If the project is constructed from the uplands, we estimate that approximately 2,000 square feet of the
shoreline will be temporarily impacted. If the project is constructed from a barge, then the anticipated
disturbance area will be approximately 500 square feet. Regardless, of the construction method, the
selected contractor will install temporary erosion and sediment controls to prevent impacts to water quality.
We anticipate that the project will be completed during daytime low tide and no work is proposed in the
GEOENGINEERS

water. We do not expect that the project will result in the discharge of material to the waters of Puget Sound
or onto the beach. However, there may be minor incidental fall back of material to the upper beach. If so,
the contractor will immediately remove this small amount of material. The existing consolidated material
waterward of the retaining wall will remain. The unconsolidated, sliding material will be removed.
Following construction of the retaining wall, the disturbed area will be restored to existing use and re -
vegetated. The proposed re -vegetation of the shoreline will emulate current conditions. The proposed
retaining wall will stabilize the upland slope and will prevent the loss of vegetation resulting from slides.
The owners propose to enhance the vegetation along the shoreline by removing invasive species from the
project area and installing appropriate native plant species. These plantings will benefit the shoreline
environment and provide additional shading for the created forage fish spawning habitat.
Because of the vegetation enhancements, we consider the proposed project to be a net benefit to the
current shoreline environment. The owners are committed to maintaining the restored area within their
property.
CONCLUSIONS
The owners propose to construct an approximately 25-foot long retaining wall in the regulated shoreline
area. The purpose of the retaining wall is to retain unstable upland areas. Without completing the necessary
repairs to the existing bulkhead, it is our opinion that this erosion will continue, resulting in damage to the
existing bulkhead and potentially threatens the existing shell midden. The project will result in minor
temporary disturbance to the upland area of the shoreline which will be restored following construction of
the retaining wall. We anticipate that the project will be successful in retaining upland areas and will
enhance the shoreline environment.

Summary of assumed, worst -case values:
140 = Soil unit weight (Ibs per cubic foot)
35 = Soil friction angle (deg.) - While a range of 40-45 is reasonable for this soil type,
35 is more conservative for this type of analysis and applicable over a wide range of
soil types.
0 = Cohesion for active pressure calculation purposes (conservative per FHA, 2006)
75 = Surcharge load on soil (pedestrians) (Ibs per square foot)
Sources of soil information:
(1) GeoEngineers, 2015. Revised Project Description and Assessment,
Shimer Property Retaining Wall Project, Federal Way, Washington,
File No. 21468-001-01, GeoEngineers, Seattle, WA, August 3, 2015.
"The lowest course of rock should be embedded at least 12 inches below the lowest adjacent
ground surface and must bear on firm, hard undisturbed soils."
"The rock wall face should be constructed with a batter of about 1H:4V"
"We recommend that the lowest course consist of four or five -man rock per Washington State
Department of Transportation (WSDOT) Standard Specifications Section 9-13.7."
"The rock wall should include a drainage zone behind the wall ... fully enclosed in a nonwoven
geotextile to prevent it from raveling from behind the wall. Backfill between the rock wall
drainage zone and the adjacent excavation cut slope may consist of imported sand and gravel
compacted to a firm and unyielding condition."
Surficial soils:
"Fraser age glacial outwash."
"older glacially consolidated soil"
"generally mixtures of silt, sand, and gravel"
"the soils exposed at the beach level of the Shimer property ...
are the older glacially consolidated fine grained soils"
Refer to GeoEngineers, 2015, Figure 1. Based on that figure, the layers at the proposed retaining
wall location are the following:
feet feet
MLLW NAVD
13 10.5 Beach dune juncture, with "COBBLE BEACH" material seaward of this point
"GLACIALLY CONSOLIDATED SOIL" between 13 & 16 feet MLLW & under cobble

"GLACIAL OUTWASH DEPOSITS AND FILL" above 16 feet MLLW

Using WSDOT, 2013, we could assume the following for design purposes:
Outwash above 16' MLLW / 13.5' NAVD (p. 5-27):
40 to 45 (see = Shear strength, range, assumed value (deg.)
above)
0 = Cohesion (Ibs/square foot)
Version ri
Date
Date
WSDOT, 2013 does not cite specific properties for "Glacially Consolidated Soil" but
does discuss the Washon Stade of the Fraser Glaciation". WSDOT, 2013, p. 5-26 goes on
to cite the following properties:
40 to 45 (See above) = Internal friction angle, range, assumed value (deg.)
100 to 1000 100 = Cohesion, range, assumed value (Ibs/square foot)
130 to 140 140 = Unit weights, range, assumed value (Ibs/cubic foot)
(The higher value will also lead to more outward force on the
wall from the soil mass behind it)
Additional note from WSDOT, 2013:
"Glacial till that is exposed as a result of excavation, slope instability, or other
removal of overlying material will degrade and lose strength with weathering."
So, we should probably assume a low cohesion. FHA, 2006 states:
"Because effective (drained) friction angles are generally used for design, it is
common to conservatively assume that soil cohesion is zero. This results in a
higher active pressure on the back of the rockery and removes uncertainty
regarding non -uniform or problematic soils..."

Project Description: The applicant proposes to construct an approximately 25-foot long rock retaining wall near the
shoreline at the property and perform minor repairs to the existing rock bulkhead. The rock
retaining wall will tie into the existing rock bulkhead and the new wall will be constructed
landward of ordinary high water mark.
The purpose of the project is to prevent ongoing erosion and failure of the bank located along
the shoreline. The bank is prone to failure and is resulting in a loss of property. The retaining
is designed to prevent future property loss. Also, the existing rock bulkhead protects a
culturally sensitive shell midden. Continued erosion of the bank threatens this historic artifact.
The proposed retaining wall is also intended to protect the shell midden.

APPEALS INFORMATION
If you wish to appeal the issuance, denial, conditioning, or modification of a Hydraulic Project Approval (HPA),
Washington Department of Fish and Wildlife (WDFW) recommends that you first contact the department employee who
issued or denied the HPA to discuss your concerns. Such a discussion may resolve your concerns without the need for
further appeal action. If you proceed with an appeal, you may request an informal or formal appeal. WDFW encourages
you to take advantage of the informal appeal process before initiating a formal appeal. The informal appeal process
includes a review by department management of the HPA or denial and often resolves issues faster and with less legal
complexity than the formal appeal process. If the informal appeal process does not resolve your concerns, you may
advance your appeal to the formal process. You may contact the HPA Appeals Coordinator at (360) 902-2534 for more
information.

The purpose of this revised letter report is to present GeoEngineers, Inc.'s (GeoEngineers) observations
and assessment of environmental conditions associated with the Shimer Property Retaining Wall project
(project). We also evaluated the project's potential impacts to the environment at the site. Recently, the
owners observed unstable areas in the upland portion of their property near the shoreline. It is our
understanding that the owners are seeking authorization from the City of Federal Way (City) to construct a
new retaining wall. The purpose of the retaining wall is to retain these unstable upland slopes and to protect
known shell midden deposits.
The Shimer property is located at 2876 SW 300th Place in Federal Way, Washington on tax
parcel 416660-0185. The Shimer property is mapped on Sheet 1 of the project design included
as Appendix A. The parcel is located on Puget Sound and contains approximately 60 linear feet of
shoreline. An existing rock bulkhead protects approximately 35 linear feet of the eastern portion of
the shoreline from tidal and wave action. It is our understanding that the owners constructed the existing
rock bulkhead in 2006 and it protects a known culturally sensitive shell midden located immediately
landward of the existing rock bulkhead. The remaining western portion, approximately 25 linear feet, of the
shoreline is unprotected. Since 2006, the end of the existing bulkhead has been damaged by wave action.
Also, unstable upland slopes have experienced sliding.
The owners contracted Coast and Harbor Engineering of Edmonds, Washington to complete a design for an
upland wall to retain unstable slopes while setting back from the ordinary high water mark (OHWM) to allow
for natural shoreline beach conditions. The owners previously sought approval for a bulkhead, which was
denied. Accordingly, Coast and Harbor Engineering developed the proposed retaining wall concept to
accomplish this goal.

PROJECT DESCRIPTION
The owners propose to construct an approximately 25-foot long rock retaining wall on the upland near the
shoreline and perform minor repairs to the existing rock bulkhead. The project design is included as
Appendix A to this letter. The rock retaining wall will tie into the existing rock bulkhead and the new wall will
be constructed landward of OHWM.
The purpose of the project is to retain unstable upland slopes. The upland slopes are prone to slides and
resulting in a loss of soil. Also, the existing rock bulkhead protects a culturally sensitive, shell midden. The
proposed bulkhead repair and retaining wall are intended to protect the shell midden. Without the repair
and tie in to the retaining wall, the bulkhead will continue to experience damage.
The proposed retaining wall can feasibly be constructed from a barge stationed on the beach or from the
upland. The construction method will be determined based on bids received from potential contractors.
However, working from above will likely reduce the risk of disturbing the hard native soil located below and
waterward of the wall. Regardless of the construction method, footings will be excavated using a small to
medium sized excavator. Excavation will be the minimum required for wall footings and existing
consolidated material will remain. The retaining wall will be constructed with approximately 20 cubic yards
of rock. The top of the proposed retaining wall will be constructed at approximate Elevation 21 feet mean
lower low water (MLLW) and will include a subsurface drain to alleviate hydrostatic pressure behind the
wall. The retaining wall will be backfilled with 1-inch drain rock. Material that is located waterward of the
face of the new retaining wall will be excavated and removed from the site.
The upland retaining wall creates the opportunity for passive restoration of new beach habitat waterward
of the wall. Existing consolidated material will remain, but unconsolidated sliding material will be removed,
allowing for natural beach condition. Upon completion of the new retaining wall, the contractor will restore
and enhance the disturbed upland area. The contractor will install native and appropriate ornamental shrub
species in the areas disturbed by construction.
ROCK WALL DESIGN AND CONSTRUCTION CONSIDERATIONS
We have reviewed the general plans prepared by Coast & Harbor Engineering for the rock walls that will be
used to support the upper portion of the slope. We also understand the rock walls will be supported by the
hard native soil, and be set back and above the beach level (see attachments to this letter). In our opinion,
the upper portion of the slope at the site may be faced with rock walls, provided certain limitations are
understood as discussed below. It is important to realize that these rock walls do not provide the same
level of soil retention as a structural wall, and are therefore not intended as retaining structures. The
primary purpose of this type of rock wall is to protect the upper portion of the slope face from erosion and
raveling, while providing limited soil retention and support. Rock walls are an alternative wall type which
are usually less costly than structural walls but involve more risk of failure. There is always some risk of
rock wall movement or failure even when the foundation soil and retained material are satisfactory and the
rock wall materials and construction are satisfactory. It is also important to understand that the hard native
soils located below and waterward of the bottom of the wall will erode slowly under the expected wave and
storm actions. Future wall repairs may be needed to reduce the risk of slope failure.
Properly constructed rock walls are typically used to face slopes up to about 6 feet in height when
unreinforced, and to heights in excess of 8 feet in reinforced fills and dense native soils. With the soil
conditions encountered at the site, we expect these walls will primarily be facing dense native soil
conditions, except for the upper couple of feet which may be fill or weathered soil.

Revised Project Description and Assessment August 3, 2015 Page 3
An experienced and skillful craftsman in rock wall construction should install these walls. The lowest course
of rock should be embedded at least 12 inches below the lowest adjacent ground surface and must bear
on firm, hard undisturbed soils. Care must be taken during excavation to avoid disturbance of the hard
native soil located waterward of bottom of the wall. It is likely that working from above will reduce the risk
of disturbing the hard native soil located waterward of the bottom of the wall. The rock wall face should be
constructed with a batter of about 1H:4V (horizontal to vertical). Rock courses should be gradational in size
from top to bottom with the largest rocks of uniform size being placed for the lowest course. We recommend
that the lowest course consist of four or five -man rock per Washington State Department of Transportation
(WSDOT) Standard Specifications Section 9-13.7. The contact between each rock course should slope
downward to the back side of the rock wall. Each course of rocks should be seated tightly and evenly on
the course beneath so each rock rests on two rocks below. Rock selection and placement should limit voids
in the exposed face of the wall and allow no open voids of over 6 inches across in any direction. After
seating each course of rock, all voids between the rocks should be chinked on the back side with quarry
spalls to eliminate passage of backfill material.
The rock wall should include a drainage zone behind the wall. This zone may consist of washed drain rock
fully enclosed in a nonwoven geotextile to prevent it from raveling from behind the wall. Backfill between
the rock wall drainage zone and the adjacent excavation cut slope may consist of imported sand and gravel
compacted to a firm and unyielding condition.
SHORELINE ASSESSMENT
A GeoEngineers biologist and geotechnical engineer completed a shoreline assessment at the site on
May 28, 2014. The GeoEngineers biologist also performed site visits on March 27, 2014 and
December 18, 2014. In attendance at the December 2014 site visit were representatives from the City and
Washington State Department of Ecology (Ecology).
Geologic Conditions
Prior to our shoreline assessment, we reviewed the Washington Department of Natural Resources (DNR)
Interactive Geologic Map online and the US Geologic Survey (USGS) "Geologic Map of the Poverty Bay
Quadrangle" dated 2004 that identified the surficial soils at the site as Fraser age glacial outwash. Glacial
drift of the Fraser glaciation is also identified in the area as is older glacially consolidated soil along the
shoreline to the north of the site. The outwash deposits mapped at the site are generally mixtures of silt,
sand and gravel that have been deposited by streams during and following the last glacial advance.
Whereas the underlying drift can include glacially consolidated silt, sand and gravel that is dense and
relatively erosion resistant, the older glacial consolidated deposits identified north of the site are
predominantly fine grained silt and clay. In our opinion, the soils exposed at the beach level of the Shimer
property and discussed below are the older glacially consolidated fine grained soils (Figure 2).
We scheduled our shoreline assessment during a low tide event. The tidal elevation during our site
assessment was approximately -1.1 feet (MLLW). Immediately west of the owners' existing rock bulkhead,
we observed an approximately 8-foot high bank that extends into the City right-of-way (ROW) located
immediately west of the Shimer parcel. We observed a failure of the bank and the failed material ended up
on the beach. Some of this sloughed material has been subsequently eroded and transported via wave and
tidal processes. The unprotected bank on the Shimer property is vegetated with shrub species which
overhangs the beach. According to the owners, this bank failed in 2013 and is isolated to their property

and does not encroach into the City ROW. It appears that the fully vegetated bank failed episodically and
this failure resulted in a recession of the top of the bank of approximately 7 feet.
According to the owner, additional material from the bank sloughed on to the beach following a December
2014 storm.
Photo 1: Shimershoreline facing southeast.
The City constructed a rock -lined stormwater outfall within the ROW west of the Shimer parcel. In general,
the City ROW is vegetated in noxious and invasive knotweed (Polygonum spp.) and willows (Salix spp.). A
primitive public access trail to the beach is located in the City ROW. At the toe of the bank, within the City
ROW we observed a near vertical, relatively resistant native soil layer that appears to be glacially
consolidated fine grained deposit with some gravel. This layer is approximately 3 to 4 feet thick above the
elevation of the beach and is overlain by unconsolidated soil that appears to be fill material or native
outwash soils that have been mapped at the site, extending to the top of the bank.
Based on our observations at the site, it appears that the harder underlying glacially consolidated soil is
relatively resistant to wave and tidal action. However, the overlying softer soils and unconsolidated fill and
outwash soil is subject to sloughing. Because the failed bank is fully vegetated, it appears that the
vegetation is not effective in preventing the undermining of the erodible material in the bank.
In our opinion, the unconsolidated outwash and fill material in the upper portion of the bank will continue
to episodically fail. As illustrated in the Figure 2, if no action is taken to arrest on -going slope failure, we
anticipate that the slope will, minimally, experience landward migration to a 1.5H:1V (horizontal to vertical)
slope from the top of the glacially consolidated soil. By factoring in groundwater saturation that appears to
be perched on this relatively impervious material, we expect that the slope will continue to slump to 2H:1V
slope with a concave -shaped profile. Slope failure of this nature may result in the landward migration of the
top of the slope approximately 10-15 feet from the pre-2013 top of slope location. The underlying glacially
consolidated soil is expected to erode but at a much slower rate.

Habitat Conditions
During the site visits, the GeoEngineers biologist documented intertidal habitat conditions of the beach
waterward of the Shimer property and the upland shoreline environment. In general, the beach consists of
coarse gravel and cobble. This beach substrate is typical of high energy (tidal and wave) Puget Sound
intertidal habitats. These intertidal habitats are primarily used by forage fish, crabs and numerous small
invertebrates. Shorebirds, herons and raptors also forage for prey in these shallow water habitats.
At the upper beach, within the City ROW, we observed a small (approximately 20 square foot) area of beach
consisting of gravel and sand with many shell fragments. This beach substrate may be used as spawning
habitat for surf smelt (Hypomesus pretiosus). Surf smelt spawning in this area of Puget Sound is expected
to occur in the fall and winter. Because of the lack of fine beach substrate (small gravel and sand), we do
not expect that Pacific sand lance (Ammodytes hexapterus) utilize the beach on the Shimer parcel for
spawning. However, Pacific herring (Clupea pallasii) spawning habitat exists within the lower beach in the
areas vegetated by eelgrass (Zostera spp.) which we observed approximately 200 feet waterward of the
shoreline. The Washington Department of Fish and Wildlife (WDFW, 2014a) does not document the
presence of forage fish spawning near the site.
Pacific salmon, including federally protected species are present in the intertidal areas of Puget Sound.
However in is unlikely that they extensively utilize the upper beach and would only be in the proximity of the
shoreline during high tide events.
Residential development substantially limits nearshore habitat conditions along the shoreline. The
unprotected bank on the Shimer parcel and the City ROW are the only unprotected portions of the shoreline
that we observed in the immediate vicinity. The shorelines of the adjacent parcels have been armored,
primarily with concrete bulkheads, and much of the shoreline vegetation has been removed. Because of
the presence of overhanging vegetation on the Shimer parcel and City ROW, nearshore habitat conditions
are somewhat less degraded than the shoreline habitat in the vicinity of the site. Currently, the vegetation
on the Shimer shoreline consists of shrubs including, snowberry (Symphoricarpos albus), Nootka rose
(Rosa nutkana) and Himalayan blackberry (Rubus armeniacus).
At the time of our site visit, we observe no accumulation of woody material on the beach. It appears that
the wave and tidal energy at the site, the presence of shoreline armoring in the vicinity of the site and the
dramatic shift in the natural beach profile (Figure 1) on the Shimer parcel preclude the accumulation of
coarse woody debris along the shoreline.
IMPACT ANALYSIS
Because the proposed retaining wall will be constructed landward of OHWM, we expect that there will be
no negative impacts to the aquatic habitat of Puget Sound.
The project will result in minor temporary disturbance to the upland area of shoreline during construction.
If the project is constructed from the uplands, we estimate that approximately 2,000 square feet of the
shoreline will be temporarily impacted. If the project is constructed from a barge, then the anticipated
disturbance area will be approximately 500 square feet. Regardless, of the construction method, the
selected contractor will install temporary erosion and sediment controls to prevent impacts to water quality.
We anticipate that the project will be completed during daytime low tide and no work is proposed in the
GEOENGINEER�
File No. 21468-001-01
Revised Project Description and Assessment August 3, 2015 Page 6
water. We do not expect that the project will result in the discharge of material to the waters of Puget Sound
or onto the beach. However, there may be minor incidental fall back of material to the upper beach. If so,
the contractor will immediately remove this small amount of material. The existing consolidated material
waterward of the retaining wall will remain. The unconsolidated, sliding material will be removed.
Following construction of the retaining wall, the disturbed area will be restored to existing use and re -
vegetated. The proposed re -vegetation of the shoreline will emulate current conditions. The proposed
retaining wall will stabilize the upland slope and will prevent the loss of vegetation resulting from slides.
The owners propose to enhance the vegetation along the shoreline by removing invasive species from the
project area and installing appropriate native plant species. These plantings will benefit the shoreline
environment and provide additional shading for the created forage fish spawning habitat.
Because of the vegetation enhancements, we consider the proposed project to be a net benefit to the
current shoreline environment. The owners are committed to maintaining the restored area within their
property.
CONCLUSIONS
The owners propose to construct an approximately 25-foot long retaining wall in the regulated shoreline
area. The purpose of the retaining wall is to retain unstable upland areas. Without completing the necessary
repairs to the existing bulkhead, it is our opinion that this erosion will continue, resulting in damage to the
existing bulkhead and potentially threatens the existing shell midden. The project will result in minor
temporary disturbance to the upland area of the shoreline which will be restored following construction of
the retaining wall. We anticipate that the project will be successful in retaining upland areas and will
enhance the shoreline environment.

Re: File #13-103907-00-SH; TECHNICAL RESPONSE LETTER #3
Shimer Bulkhead, 2876 SW 300th Place, Federal Way
Dear Ms. Kaylor:
FILE.
City staff, in consultation with staff from the Department of Ecology, has reviewed the June 11, 2015,
resubmittal of plans for proposed shoreline modification improvements at the above -referenced property.
The city supports your proposal to maintain/repair the existing bulkhead with the bulkhead repair stones as
shown on Sheet 3 of the proposed site plan, but staff is not supportive of the excavation and removal of the
existing bluff along the remaining shoreline with replacement hardened armor. The following provides
technical code analysis, suggested alternatives, and next steps for your proposal.
TECHNICAL COMMENTS
City staff supports the cap of the existing bulkhead as it meets substantial development exemptions for
normal maintenance or repair of existing structures pursuant to RCW 90.58.030(3)(e)(i). However, the
proposed retaining wall appears to be an extension of the existing bulkhead and is therefore considered new
armoring. Additional armoring of this shoreline is not permitted by Federal Wray Revised Code (FWRC)
15.05.050(1)(a)(iii), as no evidence has been provided of any clear and imminent danger to a Shoreline Master
Program (SMP) defined primary structure and/or substantial accessory structures.
Following review of the Shoreline Assessment and Mitigation memo prepared by GeoEngineers, the proposed
retaining wall is essentially a bulkhead as it contains all the attributes of the following SNIP definition:
FWRC 15.05.030 — `Bulkhead means a wall, seawall, embankment, or other structure erected at or
near the [Ordinary High Water Mark] OHWM and roughly parallel to the shoreline that retains or
prevents sliding or erosion of land or protects land and/or structures from wave or current action."
Sheet 3 shows the proposed structure (following bluff removal) at distances ranging from approximately one
to five feet from the OHNVM and the structure is parallel to the shoreline.
Page 2 of the report states, "[t]he purpose of the project is to prevent ongoing erosion and failure of the bank
located along the shoreline." The report also states in part that, "Coast and Harbor Engineering found that
soft shoreline stabilization strategies were inappropriate and not effective for this location because of the high
tidal and wave energy[...]"
33325 8th Avenue South, Federal Way, WA 98003-6325 (253) 835-7000 o www.cityoffederalway.com
Ms. Courtney Kaylor
Page 2
July 1, 2015
The wall is near the OHWM and parallel to the shoreline. The purpose of the wall is to prevent erosion from
waves and current. For these reasons, staff is unable to support the proposed improvements because they are
an extension of the existing bulkhead. Additions to the existing bulkhead are considered new structures
pursuant to FWRC 15.05.050(1)(b)(iv) and as mentioned previously, not permitted here due to the absence of
clear and imminent danger to primary and substantial accessory structures.
SUGGESTED ALTERNATIVES
The consolidated soils on the toe of the bluff function as natural shoreline stabilization that needs to be
retained and uncompromised. Staff will support efforts to stabilize the bluff with the bioretention method of
reslope revegetation. Staff support of a wall type structure will require moving the proposed wall further
landward to the extent that excavation into the consolidated material for the wall's foundation does not
compromise the integrity of the consolidated material at the toe of the bluff. A geotechnical report will need
to verify that a proposed wall will not compromise the natural stabilization the existing bluff toe provides.
CLOSING
Please resubmit four copies of an assessment and plans that coincide with the suggested alternatives listed
above with the enclosed resubmittal handout. You may contact me at xnatt.hcrre> a oFFed l�;�ay.com or
253.835.2638 if you should have any questions.

MEMORANDUM
DATE: NOVEMBER 19, 2014
TO: ISAAC CONLEN — PLANNING MANAGER
FROM: MATT HERRERA — SENIOR PLANNER
SUBJECT: SHIMER BULKHEAD ALTERNATIVE OPTIONS
I have reviewed of the applicant's consultant presentation and geotechnical/habitat memorandum that
identify two new alternative shoreline stabilization methods. I have found that, similar to the initial method
rejected by the department, both new options fail to meet the city's Shoreline Master Program criteria for
shoreline modifications FWRC 15.05.050(1) and the state legislature's preference to uses as enumerated in
the Shoreline Management Act 90.58.020 RCW.
Background
On September 4, 2013, the applicant submitted a Shoreline exemption application and SEPA checklist for a
proposed bulkhead that would extend 22-linear feet along the shoreline and return upland approximately 10-
linear feet. The subject property is located along the Puget Sound shoreline at 2876 SW 300` Pl. The eastern
portion of the property abutting the shoreline is currently armored and contains a staircase to the beach. The
western portion of the property and the adjacent city ROW is un-armored. The western portion of the
Shimer's property contains a vegetated bluff approximately 8-feet in height. Wave action at the toe has
caused some sloughing and erosion to the bluff and is potentially compromising the existing bulkhead.
Upon review of the application, I responded with a technical comment letter stating in part that: (1) the
proposal was not exempt as it did not meet `normal protective' criteria (WAC 173-27-040(2)(c) as the
Shimer's single-family dwelling unit was more than 60-feet from the shoreline to be armored; (2) hard
armoring of the shoreline would only be considered if it met the clear and imminent threat criteria set forth in
FWRC 15.05.050(1)(a)iii; (3) a shoreline variance for the proposal would be required as the bulkhead was
more than one -foot above MHHW (FWRC 15.05.050(b)(i); and (4) staff would be unlikely to support their
proposal as it appeared the purpose of the armoring was to protect the landscaped yard and not a primary or
accessory structure.
On December 19, 2013, the applicant resubmitted items responding to the technical comments from the first
round of review. The applicant's responses failed to provide any evidence that a clear and present danger to
the primary structure or any substantial accessory structures existed. Instead the applicant incorrectly

interpreted the SMA regulations to surmise that the existing bulkhead on the east portion of the property
which was potentially being compromised was an appurtenance and exempt from a Substantial Development
Permit. Additionally, the applicant incorrectly interpreted the city's SMP regulations to include the existing
bulkhead and staircase as substantial accessory structures. These two issues were further expanded on in a
second technical comment letter to the applicant which further stated the city's intent not to approve the
bulkhead as proposed as it did not meet state SMA or city SMP regulations. The letter closed with staff
support of a solution to repair/maintain the existing bulkhead without expanding or adding additional hard
armor to the shoreline.
Alternative Options Presented
On November 5, 2014, professional representatives (counsel, coastal engineer and habitat scientist) for the
applicant provided a presentation of alternative methods to the initial proposal. The presentation provided a
backdrop of the marine conditions in this region of Puget Sound and how those conditions impact the
shoreline along the Shinier property.
The value of habitat in and around the area was also discussed and it was found that due to the energy of the
wave action in this area and the prevalence of armoring along this stretch of shoreline, there was little
existing habitat value in the surrounding area proposed to be armored with the exception of approximately 20
square feet of beach consisting of gravel and sand within the adjacent city ROW. Such substrate may be used
by spawning surf smelt as identified in the GeoEngineers memorandum provided at the presentation.
The applicant's representatives stated during the presentation that no action or soft shoreline stabilization
alternatives would not be effective due to the wave exposure and fetch along this reach of shoreline. Instead,
they presented the following two options:
The first alternative includes a bulkhead setback between approximately 1-12 feet upland of the OHWM
with a pocket beach consisting of native sand, gravel and cobble backfill. The second alternative provides a
boulder toe along the OHWM with a bio-engineered slope with a stepped wall with native planting along the
slope. Both options continue as an extension of the existing bulkhead along the remainder of the un-armored
portion of the Shimer's property.
Analysis
Both alternative options presented on November 5 appear to be less of an impact on the shoreline than the
initial proposal, but two issues keep the alternatives from being consistent with the SMA and SMP and
therefore should not be supported by staff.
First, both options are still considered hard armoring. The SMP (FWRC 15.05.050(1)(a)(iii) provides the
following criteria for this method of shoreline stabilization:
In the case of proposed hard armoring stabilization solutions (e.g., bulkheads and riprap), erosion
from waves or currents presents a clear and imminent (damage within three years) threat to a legally
established primary structure, one or more substantial accessory structures, water -dependent
development, ecological restoration/toxic clean-up remediation projects, or public improvements
As mentioned previously, the established primary structure (SF dwelling unit) is more than 60-feet from the
sloughing bluff and potentially failing existing bulkhead. No other substantial accessory structures as defined
by the SMP are located on the property. Any approval for new hard armoring would contradict this
regulation.
2
Second, both options create new armoring that is not `normal protective' to single-family residences as its
sole purpose does not protect the existing single-family residence or appurtenant structure as defined by the
SMA (WAC 173-27-040(2)(g). The presentation by the applicant's representatives and the memorandum
from GeoEngineers indicate the purpose of the additional shoreline modification is to prevent the continued
bank erosion and disturbance of buried cultural resources. Neither the SMA or SMP identify cultural
resource protection as a need for hard armoring the shoreline nor does the primary structure require shoreline
protection as it is more than 60-feet from the sloughing bluff.
As mentioned previously, both alternatives appear to result in less of an impact to the shoreline than the
initial proposal and the typical armoring that has occurred on the surrounding properties. The pocket beach
alternative would potentially provide onsite habitat mitigation and the bio-engineered slope would provide
nearshore vegetation, but allowing the feeder bluff to erode naturally would also benefit the shoreline
habitat. It should be noted that a contributing factor to the degraded habitat along this reach of shoreline is
likely from the years of hard armoring that have been constructed. The small area suitable for surf smelt
spawning was found adjacent to the un-armored area of city ROW.
The proposed alternatives are appropriate stabilization in instances where a primary or substantial accessory
structure is threatened to be damaged within three years which is not the case for the subject property.
Therefore, staff should reject the two alternative options as they do not meet the criteria for hard armoring
and are inconsistent with SMA and SMP policies as indicated in the prior two technical comment letters.
Staff will continue to support the repair and maintenance of the existing bulkhead which does not result in
the continued armoring parallel to the shoreline.

Shimer Shoreline Stabilization Assessment
The purpose of this memorandum is to present our observations and assessment of site conditions associated
with the Shimer shoreline stabilization project. The Shimer residence is located at 2876 Southwest 300th Place
in Federal Way, Washington on tax parcel 416660-0185 (Figure 1). This parcel is located on Puget Sound and
contains approximately 60 linear feet of shoreline. An existing rock bulkhead protects approximately 35 linear
feet of the eastern portion of the shoreline from tidal and wave action. It is our understanding that the owners
constructed the existing rock bulkhead in 2006 and it protects a known culturally sensitive shell midden located
immediately landward of the existing rock bulkhead. The remaining western portion, approximately 25 linear
feet, of the shoreline is unprotected. Recently, the owners observed bank sloughing along the unprotected
portion of the shoreline. It is our understanding that the owners are seeking a variance to the City of Federal
Way (City) shoreline code to construct a new bank protection along the unprotected portion of the shoreline.
The purpose of the additional bank protection is to prevent continued bank sloughing, possible disturbance of
known midden deposits.
Under contract with the owners, a GeoEngineers, Inc. (GeoEngineers) biologist and geotechnical engineer
performed a site visit to document existing site conditions, assess erosion and stability of the site and support
the development of appropriate bulkhead design alternatives. During the May 28, 2014 site visit, we met with
Laurel Shimer (owner) and coastal engineers from Coast and Harbor Engineering of Edmonds, Washington. The
owners contracted Coast and Harbor Engineering to complete a shoreline stabilization assessment that
evaluates wave, tidal and sediment transport trends at the site. Coast and Harbor also evaluated the
performance of appropriate shoreline stabilization strategies based on their findings of site conditions.
Existing Site Conditions
Geologic Setting
We reviewed the Washington Department of Natural Resources Interactive Geologic Map online and the
US Geologic Survey "Geologic Map of the Poverty Bay Quadrangle" dated 2004 that identified the surficial soils
at the site as Fraser age glacial outwash. Glacial drift of the Fraser glaciation is also identified in the area as is
older glacially consolidated soil along the shoreline to the north of the site. The outwash deposits mapped at
the site are generally mixtures of silt, sand and gravel that have been deposited by streams during and following
the last glacial advance. Whereas the underlying drift can include glacially consolidated silt, sand and gravel
that is dense and relatively erosion resistant, the older glacial consolidated deposits identified north of the site
are predominantly fine grained silt and clay. In our opinion, the soils exposed at the beach level of the Shimer
property and discussed below are the older glacially consolidated fine grained soils (Figure 2).

Site Reconnaissance
We scheduled our site reconnaissance during a low tide event. The tidal elevation during our site
reconnaissance was approximately -1.1 feet Mean Lower Low Water (MLLW). Immediately west of the owners
existing rock bulkhead, we observed an approximately 8-foot high bank that extends into the City right-of-way
(ROW) located immediately west of the Shimer parcel. We observed a failure of the bank and the failed material
ended up on the beach. Some of this sloughed material has been subsequently eroded and transported via
wave and tidal processes. The unprotected bank on the Shimer property is vegetated with shrub species which
overhangs the beach. According to the owners, this failed bank is isolated to their property and does not
encroach into the City ROW. It appears that the fully vegetated bank failed episodically and this failure resulted
in a recession of the top of the bank of approximately 7 feet.
Photo 1: Shimer shoreline facing southeast.
The City constructed a rock -lined stormwater outfall within the ROW west of the Shimer parcel. In general, the
City ROW is vegetated in noxious and invasive knotweed (Polygonum spp.) and willows (Salix spp.). A primitive
public access trail to the beach is located in the City ROW. At the toe of the bank, within the City ROW we
observed a near vertical, relatively resistant native soil layer that appears to be glacially consolidated fine
grained deposit with some gravel. This layer is approximately 3 to 4 feet thick above the elevation of the beach
and is overlain by unconsolidated soil that appears to be fill material or native outwash soils that have been
mapped at the site, extending to the top of the bank.
Based on our observations at the site, it appears that the harder underlying glacially consolidated soil is
relatively resistant to wave and tidal action. However, the overlying softer soils and unconsolidated fill and
outwash soil is subject to erosion and sloughing. Because the failed bank is fully vegetated, it appears that the
vegetation is not effective in preventing the undermining of the erodible material in the bank. The hard armoring
Memorandum to Laurel an:_�ter Shimer

located east of and including the Shimer property may be resulting in end -effect erosion of the unprotected
bank. If left unprotected, we anticipate that the bank will continue to erode resulting in continued property loss
on the Shimer property and within the City ROW.
Habitat Conditions
During the site visit, the GeoEngineers biologist documented intertidal habitat conditions of the beach
waterward of the Shimer property. In general, the beach substrate is coarse gravel and cobble. This beach
substrate is typical of high energy (tidal and wave) Puget Sound intertidal habitats. At the upper beach, within
the City ROW, we observed a small (approximately 20 square foot) area of beach consisting of gravel and sand
with many shell fragments. This beach substrate may be used as spawning habitat for surf smelt (Hypomesus
pretiosus). Surf smelt spawning in this area of Puget Sound is expected to occur in the fall and winter. Because
of the lack of fine beach substrate (small gravel and sand), we do not expectthat Pacific sand lance (Ammodytes
hexapterus) utilize the beach on the Shimer parcel for spawning. However, Pacific herring (Clupea pallasii)
spawning habitat exists within the lower beach in the areas vegetated by eelgrass (Zostera spp.) which we
observed approximately 200 feet waterward of the shoreline. The Washington Department of Fish and Wildlife
(2014a) does not document the presence of these forage fish spawning near the site.
At the time.of our site visit, we observe no accumulation of woody material on the beach. It appears that the
wave and tidal energy at the site, the presence of shoreline armoring in the vicinity of the site and the dramatic
shift in the natural beach profile (Figure 2) on the Shimer parcel preclude the accumulation of coarse woody
debris along the shoreline.
Residential development substantially limits nearshore habitat conditions alongthe shoreline. The unprotected
bank on the Shimer parcel and the City ROW are the only unprotected banks that we observed in the immediate
vicinity. The shorelines of the adjacent parcels have been armored, primarily with concrete bulkheads, and
much of the shoreline vegetation has been removed. Because of the presence of overhanging vegetation on
the Shimer parcel and City ROW, nearshore habitat conditions are somewhat less degraded than the shoreline
habitat in the vicinity of the site. Currently, the vegetation on the Shimer shoreline consists of shrubs
including, snowberry (Symphoricarpos albus), Nootka rose (Rosa nutkana) and Himalayan blackberry
(Rubus armeniacus).
Evaluation of No Action Alternative
In accordance with Federal Way Revised Code (FWRC) 15.05.050 (1)(a)(i), Coast and Harbor Engineering
(2014) evaluated several shoreline stabilization strategies common to the marine environment of Puget Sound.
Coast and Harbor Engineering found that soft shoreline stabilization strategies were inappropriate and not
effective for this location because of the -high tidal and wave energy and the existing natural beach and bank
conditions at the site. Coast and Harbor Engineering developed two appropriate shoreline protection design
concepts based on their understanding of the site. GeoEngineers evaluated the potential impacts associated
with a "no action" alternative.
Under the no action alternative, the bank will continue landward recession as a result of shoreline erosion. In
our opinion, the unconsolidated outwash and fill material in the upper portion of the bank will continue to
episodically fail as a result of wave erosion. As illustrated in the Figure 2, if no action is taken to arrest on -going
bank failure, we anticipate thatthe slope will, minimally, experience landward migration to a 1.5H:1V (horizontal
to vertical) slope from the top of the glacially consolidated soil. By factoring in groundwater saturation that
Memorandum to Laurel anu --ter Shimer
October 10, 2014
Page 4
appears to be perched on this relatively impervious material, we expect that the bank will continue to slump to
2H:1V slope with a concave -shaped profile. Bank failure of this nature may result in the landward migration of
the top of the slope approximately 10-15 feet from the pre-2013 lop of slope location. The underlying glacially
consolidated soil is expected to erode but at a much slower rate.
Additionally, we anticipate that the unprotected shoreline will experience accelerated erosion due to the end
effect of the existing rock bulkhead. This accelerated end effect erosion may compromise the integrity of the
existing rock bulkhead resulting in failure of this bulkhead further to the east. This ongoing erosion presents a
clear and imminent danger to the existing bulkhead and the culturally sensitive shell midden that the existing
bulkhead was designed to protect.

RE: FILE #13-103907-00-SH; TECHNICAL RESPONSE #2
Shimer Bulkhead, 2876 SW 300`h Pl, Federal Way
Dear Mr. Zuvela:
CITY HALL
33325 8th Avenue South
Federal Way, WA 98003-6325
(253) 835-7000
www.cityoffederalway.com
City staff has reviewed the resubmitted materials intended to address items from the October 9, 2013,
Technical Comment Letter. The applicant has submitted a shoreline substantial development permit
exemption request, shoreline variance, and environmental checklist for a proposed 32 linear -foot
extension of a marine bulkhead located at 2876 SW 300`h Place. Staff is unable to issue the exemption for
the proposed scope of work and will not support the additional marine armoring as proposed for the
following reasons:
1. Exemption — The proposal is not exempt from a shoreline Substantial Development Permit
(SDP). City staff notified the applicant in the October 9, 2013, letter that the proposed bulkhead
extension is not exempt from an SDP as no evidence was provided that the bulkhead is "normal
protective" as defined in WAC 173-27-040(2)(c). The city's letter stated the single-family
residence is more than 60 feet from the proposed bulkhead and no appurtenant structures were in
danger.
Resubmitted narratives provided by Waterfront Construction have suggested the new bulkhead is
exempt under the premise that bulkheads are an "appurtenance" as defined by the state Shoreline
Management Act (SMA). On page 2 of the December 17, 2013, Waterfront response letter, the
author states:
WAC 173-27-040 states that normal protective bulkheads can be approved
under the SDP exemption process if they are designed to protect appurtenant
structures from loss or damage by erosion. As defined, an "appurtenance" is
necessarily connected to the use and enjoyment of a single-family residence
such as a bulkhead.
This is an incomplete citation of the SMA rules and leads to a supposition the armoring meets
exempt criteria. The complete definition of "appurtenance" in WAC 173-27-040(2)(g) states:
An "appurtenance" is necessarily connected to the use and enjoyment of a
single-family residence and is located landward of the ordinary high water mark
and the perimeter of a wetland. On a statewide basis, normal appurtenances
include a garage; deck; driveway; utilities; fences; installation of a septic tank
and drainfield and grading (emphasis added) which does not exceed two
Mr. Zuvela

Page 2
hundred fifty cubic yards and which does not involve placement of fill in any
wetland or wateiward of the ordinary high water mark. Local circumstances may
dictate additional interpretations of normal appurtenances which shall be set
forth and regulated within the applicable master program.
The statewide appurtenance definition does not lend itself to include other features as indicated in
the Waterfront letter. Additionally, the city's Shoreline Master Program (SMP) does not include
any additional appurtenance interpretation. As the proposal will not protect an existing single-
family residence or appurtenant structure, it is not exempt from the SDP process.
2. Hard Armoring — The city cannot support additional armoring on the shoreline as it does not
meet shoreline modification criteria set forth in the city's SMP regulations. City staff notified the
applicant in the October 9, 2013, letter that bulkhead type armoring is permitted only if erosion
from waves or currents present a clear and imminent threat (damage within three years) to a
legally established primary structure, one or more substantial accessory structures (emphasis
added), water -dependent development, ecological restoration/toxic clean-up remediation projects,
or public improvements. The applicant's geotechnical consultant Associated Earth Sciences, Inc.
has resubmitted a corrected geotechnical report that incorrectly identifies the existing bulkhead
and staircase as substantial accessory structures.
On Page 2 of the October 25, 2013, Associated Earth Science report the author states:
Based on the slump failure observed along -he exposed portion of the slope, as
described in our May 10, 2013 letter, it is our opinion that the existing bulkhead
and stone staircase are at risk for damage within 3 years (a "clear and imminent
threat", per F)VRQ, most notably as the result of soil loss due to wave and tidal
action during a storm event at high tide. This staircase represents a substantial
accessory structure which currently provides the only beach access from the
subject property[..]
Pursuant to FWRC 15.05.030, substantial accessory structure means nonprimary structures equal
to or larger than 400 square feet and in good repair. Accessory structures intended to meet this
definition are detached dwelling units, cabanas, boathouses, etc. The definition of substantial
accessory structure does not include stairs or bulkheads.
Pursuant to FWRC 15.05.050(l)(a), shoreline stabilization, including bulkheads, are not
considered an outright permitted use on the city's shorelines. No clear and imminent threats to a
legally established primary structure or substantial accessory structures have been identified and
therefore the city will not support the project as proposed.
3. Next Steps — The city would support some other solution that would protect the existing
bulkhead and stairs without expanding the bulkhead. Such maintenance would likely be exempt
and could be covered under the existing exemption application as a resubmittal. If you choose this
option, no variance would be needed and the city would refund the shoreline variance fee (minus
notice publication costs) and you may remove the yellow notice board from the property frontage.
The other option is to submit an SDP for the current proposal, which as stated above, the
department will not be in a position to approve, and then you may appeal the decision to the State
Shoreline Hearings Board.

Re: Archaeology -Permit from DAHP Required
Dear Mr. Herrera:
Thank you for contacting the Washington State Department of Archaeology and Historic Preservation
(DAHP). The above referenced project has been reviewed on behalf of the State Historic Preservation
Officer. The project area is within archaeological site 45KI732. Therefore a permit from DAHP is
required under RCW 27.53. The permit requires the services of a professional archaeologist and may take
between 45 and 60 days to issue after DAHP has received a sufficient permit application. This includes a
mandatory 30 day comment period under statute.
Thank you for the opportunity to review and comment. Please feel free to contact me if you have any
questions.
Sincerely,

Subject: RE: Shimer bulkhead
Hi Matt,
Thanks for the update. My initial read is that a bulkhead shouldn't be considered an accessory structure under the FW
SMP and thus an adjoining bulkhead shouldn't be permitted or exempted. The three year threshold applies to
primary/accessory structures being threaten by erosion in three years. There must be other alternatives that actually
repairs the existing bulkhead without the need for the new adjoining bulkhead.
Interestingly, there is a lot about % mile west of this site on SW 300`h place that has a very similar situation, but I assume
has not applied for a new bulkhead? Good comparison site.
Please keep us posted as this project progresses.

Subject: RE: Shimer bulkhead
Hi David and Patrick,
I appreciate you taking the time to look at the Shimer Bulkhead documents. Unfortunately the applicant did not take the
time to come in for a preapplication meeting for this one so it's been a tiresome back -and -forth with their primary
consultant trying to explain the newly adopted SMP regs.
On their initial exemption application we let them know that our concern was that it appeared they needed the
armoring to protect the remaining yard and landscaping on the property. They resubmitted a revised geotechnical
report that stated the additional armoring was to protect the existing bulkhead which was likely to fail within 3 years.
Since the existing bulkhead was legally permitted and we would likely view it as the substantial accessory structure,
there appears to be a path for an exemption.
The variance is needed because of the limitation of 15.05.050(1)(b)(i) which allows armoring only one -foot above
MHHW. From what I understand this limitation does not provide an adequate level of protection from tidal action and is
not a typical regulation in other jurisdictions with marine shorelines.
Again, thanks for taking a look at this. I appreciate any insights and/comments and I'll keep you in the loop as we get
closer to issuing decisions and scheduling the public hearing for the variance.

Subject: Shimer bulkhead
Hi Matt,
Thanks for sending the information on the Shimer bulkhead. It sounds like a fairly complicated situation for 22 feet of
bulkhead.
I haven't looked over all the information, but I from what I've reviewed, I don't see documentation of a structure being
threatened, which would trigger the need for the bulkhead. The failing Indian midden is a unique circumstance that I
doubt the City SMP addresses.
The October 25, 2013 Associated Earth Sciences report mentions a potential threat to the stairway from potential
undermining of the existing rock bulkhead if the adjacent erosion is allowed to continue. The City SMP code 15.05.050
(1) (a) (ii) allows hard armoring if a legally established structure or substantial accessory structure is threaten with
damage within 3 years. The report attempts to justify the bulkhead need to protect the existing Shimer bulkhead and
thus protect their stairway.
The SMP definition for substantial accessory structure states: Means non primary structures equal to or larger than 400
square feet and in good repair. Stairways don't seem to fit this definition.
Please let me know how the city plans to proceed with this project. If the City approves it, looks like it may come to
Ecology as a variance to address bulkhead height design issues.
Thanks

Regarding: Project # 13-103907-00-SH
Applicants: Laurel & Peter Shinier
2876 SW 300t' Place
Federal Way, WA 98023
Mr. Herrera,
The original Shoreline Exemption permit for bulkhead construction was approved on 1/4/2006. Work was stopped
when Indian midden was discovered on site along the top of the bank above the beach and a new bulkhead design was
approved by Federal Way on 8/4/2006. That newly approved bulkhead was designed to stop the bank from sloughing
and to provide protection from erosion where the Indian midden had been discovered embedded in the bank. When the
original bulkhead was built, Federal Way required that it stop short of extending to the western property line. The
proposed bulkhead was to extend across 75% of the property leaving the remaining 25% unprotected. Federal Way felt
the remaining unprotected portion of the exposed slope would be protected from erosion if it was vegetated with
varieties of native plants chosen to protect the bank from erosion. However, in the last year a large section of the
vegetated, unarmored bank has slid onto the beach and the native plants were carried to the beach below.
Per the engineers report submitted with the current shoreline application, the western edge of the existing bulkhead is in
danger of significant erosion due to the lack of adequate protection. If the bulkhead fails, the Indian midden behind the
bulkhead will be unprotected and this valuable cultural resource will be lost. The proposed project is to extend the
bulkhead across the remaining portion of the property to protect the bank from further erosion, which will also provide
protection of the Indian midden deposits on site.
Below is the response to the Shoreline Variance Criteria and the Impact Mitigation assessment.
15. 05.160 Shoreline Variance-
(3) A variance from the standards of the master program may be granted only when the applicant can demonstrate that
all the following conditions will apply:
(a) That the strict requirements of the bulk, dimensional, or performance standards set forth in the master program
preclude or significantly interfere with a reasonable use of the property not otherwise prohibited by the master program;
Response- The proposed variance request is to exceed the Federal Way bulkhead height limit of 1' above MHHW. To
justify the need for the variance I have attached a chart to this letter obtained from the Army Corps of Engineers
website. The chart shows historical tidal elevations taken about a mile away at Tahlequah on the south end of Vashon
Island. The information was gathered over an 18 year period from 1960 to 1978 (the most current epoch available) and
the MHHW level was determined to be 11.89'; which would limit the bulkhead height to 12.89' to meet the Federal
Way restriction for bulkhead height. I have checked the NOAA website for tidal predictions and the high tides
predicted during December 2013 through February 2014 exceed the 12.89' Federal Way maximum height for bulkheads
22 times. (See the highlighted sections of the attached tidal prediction charts.) For the same period in 2014 -2015 there
are 21 tides predicted to exceed the 12.89' tide level. These elevations do not take into account wave height or tidal
surges that occur during winter storms when waves can exceed 4'-5' above the tide level. The Army Corps chart shows
the highest estimated tide to be 17.00' +/- .5'. If there is ever a tide at the highest estimated tide level of 17.5' it will be
more than 5.6' above the MHHW line and more than 4.6' above the maximum bulkhead height allowed by Federal
Way. If a storm accompanies an extreme high tide event, the storm waves could be 6'-7' above the maximum bulkhead
height allowed by Federal Way. The additional bulkhead height is needed to protect the bank from erosion, which in
turn protects the Indian midden know to be embedded in the soils along the top of the bank.
(b) That the hardship described above is specifically related to the property and is the result of unique conditions, such
as irregular lot shape, size, or natural features, and the application of the master program, and not, for example, from
deed restriction or the applicant's own actions;
• 205 NE Northlake Way, Suite 230, Seattle, WA 98105 •
■ Ph: 206-548-9800 • Fax:206-548-1022 ■
Response- The hardship described above is a result of the natural conditions on the property, tidal action, large ship
wakes and storm waves and not from deed restrictions or any action by the applicant. The additional bulkhead height is
needed to ensure protection from the erosive effect of storm waves and large ship wakes.
(c) That the design of the project will be compatible with other permitted activities in the area and will not cause
adverse effects to adjacent properties or the shoreline environment;
Response- The proposed bulkhead is similar in height to many of the existing bulkheads in the vicinity. Both
neighboring residential properties on either side are protected by concrete bulkheads. The city property directly to the
west is not protected by a bulkhead and continues to be impacted by tides and wave action. The proposed bulkhead
extension will not increase impacts and may decrease impacts by deflecting some of the energy from waves that come
from the northeast away from the city property.
(d) That the variance authorized does not constitute a grant of special privilege not enjoyed by other properties, and will
be the minimum necessary to afford relief,
Response- As noted above, the proposed bulkhead is similar in height to many of the existing bulkheads in the vicinity
that were built before the code change at Federal Way. The proposed bulkhead is designed to mate with the height of
the existing bulkhead that was approved by Federal Way in 2006 to protect the bank from erosion and to ensure the
Indian midden remained in place.
(e) That the public interest will suffer no substantial detrimental effect;
Response- The proposed bulkhead is designed to ensure protection of the Indian midden preserving cultural heritage of
the native tribes in the area and ensures that the public interest will suffer no substantial detrimental effect.
(f) That the public rights of navigation and use of the shorelines will not be adversely affected by the granting of the
variance when the proposal is for development located waterward of the ordinary high water mark, or within wetlands,
estuaries, marshes, bogs, or swamps;
Response- The proposed bulkhead construction will not adversely affect the public rights of navigation since it is
upland of the MHHW line.
(g) That consideration has been given to the cumulative effect of like actions in an area where similar circumstances
exist, and whether this cumulative effect would be consistent with shoreline policies or would have substantial adverse
effects on the shoreline.
Response- As noted in aerial photos submitted earlier, there are bulkheads on all of the properties in either direction
within the immediate vicinity; and the portion of unprotected shoreline remaining on site and on the adjacent city
property is the only unprotected shoreline in the area.
IS 05.040 General 2nK opment Standards- (1)Impact Mitigation
(b) Where required, mitigation measures shall be applied in the following sequence of steps listed in order of priority.
(i) Avoiding the impact altogether by not taking a certain action or parts of an action;
Response- As noted in the engineers report form Associated Earth Sciences, if the shoreline is left unprotected, the
western end of the bulkhead will fail and the midden it is protecting will be exposed to the erosive effects of ship wakes
and storm waves. The proposed bulkhead extension provides the long-term bank protection needed.
(ii) Minimizing impacts by limiting the degree or magnitude of the action and its implementation by using appropriate
technology or by taking affirmative steps to avoid or reduce impacts;
Response- The proposed bulkhead is the minimum necessary as per the engineers report. Left unprotected the bank
will slough again and the Indian midden will be lost.
■ 205 NE Northlake Way, Suite 230, Seattle, WA 98105
■ Ph:206-548-9800 ■ Fax:206-548-1022 ■
(iii) Rectifying the impact by repairing, rehabilitating, or restoring the affected environment;
Response- The original bulkhead permits required native vegetation to be planted in the location of the proposed
bulkhead. As noted above, the vegetation failed to provide adequate protection from wave action and a large section of
the bank slid onto the beach carrying the mitigation native vegetation with it. Most of the vegetation that slid has died
on the beach or been washed away. The proposal includes new native vegetation along the top of the bulkhead.
(iv) Reducing or eliminating the impact over time by preservation and maintenance operations;
Response- The proposed bulkhead has been engineered to provide a long term solution to bank erosion which in turn
will protect the proposed native vegetation that will be planted above the bulkhead. Vegetation will be maintained to
ensure survival and long term habitat benefits.
(v) Compensating for the impact by replacing, enhancing, or providing substitute resources or environments;
Response- The proposed bulkhead project includes replacement of lost vegetation and enhancement of shoreline native
vegetation directly behind the bulkhead, across the property.
(vi) Monitoring the impact and the compensation projects and taking appropriate corrective measures.
Response- The proposed bulkhead will be monitored by the applicants to ensure stability; and the native vegetation
planted as mitigation will be monitored to ensure a minimum 80% survival rate after 5 years as required by the Army
Corps of Engineers.
If you have any questions or comments on these responses please contact me and I will address your concerns ASAP.

Subject: Shimer Bulkhead — Response to City Comments
2876 SW 300t' Place
Federal Way, Washington
Dear Mr. and Mrs. Shimer:
RECEIVED
DEC 18 2013
CITY OF FEDERAL WAY
CDS
At the request of Waterfront Construction, Inc. (Waterfront), Associated Earth Sciences, Inc.
(AESI) has prepared this letter providing our responses to selected comments made in the City of
Federal Way's (City's) "Technical Comment Letter," dated October 9, 2012, regarding the
proposed bulkhead extension at the subject address. We have previously prepared a letter, dated
May 10, 2013, which documented our observations of the shoreline at the subject site and
provided recommendations for the extension of the existing rock bulkhead. This letter is
arranged to reply to the following geotechnical comments,(Items 1 through 5) as they appear in
the referenced Federal Way review letter.
1. Exemption — The applicant has not provided evidence that the bulkhead is "normal
protective" as identified in WA 173-27-040(2)(c), and therefore, an exemption cannot
be issued. A normal protective bulkhead's sole purpose is protecting an existing single-
family residence and appurtenant structures from loss or damage by erosion. It appears
the closest proximity of the proposed bulkhead and residence is more than 60 feet. If
there is not a current need for shoreline stabilization, a substantial development permit
will be required. Please provide evidence that the scope of work complies with
exemption criteria.
In our May 10, 2013 report, we provided our opinion that soil loss due to wave and tidal action
would eventually lead to erosion of the soil behind the existing rock bulkhead, ultimately leading
to the collapse of the existing bulkhead, along with the stone staircase which currently provides
pedestrian access to the beach. Under Washington Administrative Code (WAC) 173-27-
040(2)(g), an "appurtenance" is described as being "connected to the use and enjoyment of a
single-family residence," and ay include such minor structures as decks, fences, and even site
grading of less than 250 cub
c yards. Based on the waterfront location of the existing residence,
it is our opinion that the ex' ting bulkhead with the stone staircase beach access, along the gravel
Kirkland Everett Tacoma
425-827-7701 425-259-0522 253-722-2992
www.aesgeo.com
pathways and stone fire pit near to shoreline, is necessarily connected to the use and enjoyment
of the waterfront residence and, therefore, should qualify the proposed bulkhead extension for an
exemption. ---I ,r�s� �� na�r
2. Hard .Armoring — Pursuant to Federal Way Revised Code (FWRC) 15.05.050(1)(a)(M),
bulkhead type armoring is permitted only if erosion from waves or currents present a
clear and imminent threat (damage within three years) to a legally established primary
structure, one or more substantial accessory structures, water -dependent development,
ecological restoration/toxic clean-up remediation projects, or public improvements. No
evidence has been provided that such improvements are in harm's way.
The geotechnical report identified gravel path, irrigation line, landscaping and future
soil loss as reasons for shoreline stabilization. It was further stated that the bulkhead is
necessary to provide a stable shore access and to protect private and public property
from shoreline erosion and ground loss. These items do not meet the criteria listed
above. Unless the house, or substantial accessory structures, is within imminent threat, a
hard armoring solution will not be allowed and soft -shore stabilization alternatives will
need to be utilized (see item #5 below).
nor cx- Shore access from the subject property is currently provided by a stone staircase which leads
through the existing bulkhead to the beach. Based on the slump failure observed along the
ex osed portion of the slope, as described in our May 10, 2013 letter, it is our opinion that the
existin bu ead d stone staircase are at risk for damage within the next 3 years (a "clear and
n� imminent threat", per FWRC), most notably as the result of soil loss due to wave and tidal action
`--�,,Iauring a storm event at high tide. This aircase represents a substantial accessm struc urR
which current y provides the only beach access from the subject property which, as stated above,
is connected to the use and enjoyment of the subject waterfront residence.
Additionally, for the city to approve the bulkhead, the geotechnical report and/or plans
will also need to identify the following items from FWRC 15.050.050(1)(a):
• Identify where the OHWM is located or identify that the MHHW is being utilized
as permitted by WAC 173-22-030. Provide commentary how this line was
established and identify the qualified professional who made the determination.
We understand that MHHW is being utilized by Waterfront, and that the Mean
Higher High Water (MHHW) elevation of 11.89 feet, as presented in the attached
U.S. Army Corps of Engineers (USACE) tide chart (90B — Tahlequah), is
assumed. We also understand that site topography is based on the U.S. Coast and
Geodetic Survey Marker, located roughly 60 feet from the subject property.
• An explanation of how the bulkhead meets the, "minimum size necessary to
protect existing improvements. "
Due to the recent and past slump failures documented as extending upward to the
nearby gravel path along the exposed portion of the slope, it is our Minion that a
2
bulkhead facia the e ht of the slo a is needed to Leduca the azcuacacc
of soil loss from the waves.
■ Demonstrate that impacts to sediment transport are minimized to the greatest
extent possible.
Our review of the Coastal Zone Atlas of Washington, Volume 6, King County
(1979, Washington State Department of Ecology, Sheet KI 10, scale 1:24,000)
indicates that the area of the subject site is not a feeder bluff, and that coastal
drift, minimal in magnitude, approaches the area of the subject site from both the
east and west, during both summer and winter. Therefore, it is our opinion that
the impact to sediment transport posed by the proposed stabilization is minimal.
Demonstrate that the proposed stabilization will not have an adverse impact on
the property of others and shall be designed so as not to create the need for
shoreline stabilization elsewhere. (How will this bulkhead extension affect the
neighboring public right-of-way?)
It is our opinion that the proposed stabilization will not have an adverse impact on
adjacent private properties, as both currently include concrete bulkheads. As
stated in our May 10, 2013 letter, slope toe erosion was observed at the City right-
of-way. In our opinion, this erosion will continue in a similar fashion subsequent
to the installation of the proposed stabilization at the subject property.
A native revegetation plan prepared by a qualified professional with native plants
is required.
We understand that a revegetation plan is currently under development.
■ Demonstrate how the stabilization shall not otherwise result in a net loss of
ecological functions.
With the installation of suitable native plantings, it is our opinion that proposed
stabilization should not result in a net loss of ecological functions.
3. Variance Needed — Pursuant to FWRC I5.05.050(b)(i), the maximum height of the
proposed bulkhead, or other structural stabilization, is no more than one foot above the
elevation of mean higher high water on tidal waters measured from grade on the
waterward side of the bulkhead or structure. The plans identify the bulkhead at eight feet
above MHHW, and therefore, would require a shoreline variance permit.
We understand that the City has a concern regarding the construction of a bulkhead which
extends more than 1 foot above the Mean Higher High Water (MHHW) elevation of 11.89 feet,
as presented in the attached U.S. Army Corps of Engineers (USACE) tide chart (90B —
Tahlequah). Based on our review of a "Proposed Bulkhead Section" provided by Waterfront, the
elevation at the toe of the proposed bulkhead extension is roughly 12 feet, with top of the
existing slope, and proposed bulkhead, extending up to roughly Elevation 20 feet. Our review of
the attached tide chart indicates that the Highest Estimated Tide may reach up to Elevation 17.5
feet, inundating much of the existing slope or proposed bulkhead. Given the potential for storm
waves during times of extreme high tide, it is our opinion that the construction of a rock
bulkhead extending to the top of the existing slope, to match the existing bulkhead to the west, is
warranted to mitigate the effects of surface erosion and soil piping from behind the existing
bulkhead.
4. Cultural Resources — The submitted archeological report was prepared for the existing
bulkhead that was constructed in 2006 The report does not identify the proposed work
that is now under review. Pursuant to FWRC 15.050.040(6), a separate site inspection
and evaluation by a professional archaeologist for the proposed scope of work will be
necessary prior to any approvals. The evaluation shall include recommendations for
monitoring of potentially disruptive activities, data recovery, and/or mitigation
measures. Monitors from the Puyallup and Muckleshoot Tribes and additional
mitigation may also be required per State Environmental Policy Act (SEPA) procedures.
We understand that a new archeological report may be needed for the proposed project. We
understand that the existing bulkhead was permitted with the understanding that its role was to
protect culturally sensitive deposits identified in 2006. In our May 10, 2013 report, we provided
our opinion that soil loss due to wave and tidal action would eventually lead to erosion of the
soil behind the existing rock bulkhead. That eroded soil, in this case, would likely include the
culturally sensitive deposits which the existing bulkhead is currently intended to protect.
Therefore, regardless of the potential presence of additional culturally sensitive deposits at the
subject site, it is our opinion that the proposed bulkhead extension and return structure will
mitigate the risk of erosion and piping posed to the soil behind the existing bulkhead, including
the associated culturally sensitive deposits.
5. Alternative Solution — As proposed, it is unlikely staff will support the hard armoring
approach detailed in your submittal as its purpose is to protect a landscaped backyard
and not a primary structure on the subject property. Staff would support a soft -shore
stabilization solution using a bio-engineered approach. Soft -shore stabilization will still
require a substantial development permit if its purpose does not meet the exemption
mentioned in item #1. The soft -shore solution will also be required to meet applicable
criteria set forth in FWRC 15.05.050(1)(a), and will likely require third party review.
In our May 10, 2013 letter, we provided our opinion that a bioengineered solution, such as using
plants or other approved natural material to stabilize the shore, will not provide an effective level
of shoreline stabilization. In addition, given that the existing bulkhead was constructed in 2006
in response to slumping along the exposed portions of the shoreline, and that subsequent
slumping had since taken place, carrying existing plantings to the beach, a bioengineered
approach for this particular situation does not appear suitable.
9
Plan Review
We understand that the City of Federal Way has required a geotechnical review of the project
plans as a condition of approval. We have been provided with a set of plans for our review.
These plans include Sheets 1 and 2, Waterfront Construction, Inc., dated November 8, 2013.
Based on our review, the plans appear to be in general accordance with our geotechnical
recommendations outlined in our May 10, 2013 letter.
If you should have any questions concerning this letter, please do not hesitate to call our office.

Re: File #13-103907-00-SH; TECHNICAL COMMENT LETTER
Shimer Bulkhead; 2876 SW 3001h Place, Federal Way
Dear Ms. Ulgado:
City staff has reviewed the shoreline substantial development permit exemption request and
environmental checklist for a proposed 32 linear foot extension of a marine bulkhead located at 2876 SW
3001h Place. Staff is unable to issue the exemption and will delay issuing the environmental determination
until the following technical items are addressed:
1. Exemption — The applicant has not provided evidence that the bulkhead is "normal protective" as
identified in WAC 173-27-040(2)(c), and therefore, an exemption cannot be issued. A normal
protective bulkhead's sole purpose is protecting an existing single-family residence and appurtenant
structures from loss or damage by erosion. It appears the closest proximity of the proposed bulkhead
and residence is more than 60 feet. If there is not a current need for shoreline stabilization, a
substantial development permit will be required. Please provide evidence that the scope of work
complies with exemption criteria, or submit a substantial development permit application with the
associated fee of $2,756.50 and the additional information referenced below.
Hard Armoring — Pursuant to Federal Way Revised Code (FWRC) 15.05.050(1)(a)(iii), bulkhead type
armoring is permitted only if erosion from waves or currents present a clear and imminent threat
(damage within three years) to a legally established primary structure, one or more substantial
accessory structures, water -dependent development, ecological restoration/toxic clean-up remediation
projects, or public improvements. No evidence has been provided that such improvements are in
harm's way.
The geotechnical report identified a gravel path, irrigation line, landscaping and future soil loss as
reasons for shoreline stabilization. It was further stated that the bulkhead is necessary to provide a
stable shore access and to protect private and public property from shoreline erosion and ground loss.
These items do not meet the criteria listed above. Unless the house, or substantial accessory
structures, is within imminent threat, a hard armoring solution will not be allowed and soft -shore
stabilization alternatives will need to be utilized (see item #5 below).
Ms. Susan Ulgado

October 9, 2013
Additionally, for the city to approve the bulkhead, the geotechnical report and/or plans will also need
to identify the following items from FWRC 15.050.050(1)(a):
■ Identify W- here:14 M OK is located or identify that the MHHW is being utilized as permitted by
WAC 1'13-22-030. Prude commentary how this line was established and identify the qualified
professional that made who made the determination.
• An explanation of how the bulkhead meets the, "minimum size necessary to protect existing
improvements."
• Demonstrate that impacts to sediment transport are minimized to the greatest extent possible.
■ Demonstrate that the proposed stabilization will not have an adverse impact on the property of
others and shall be designed so as not to create the need for shoreline stabilization elsewhere.
(How will this bulkhead extension affect the neighboring public right-of-way?)
• A native revegetation plan prepared by a qualified professional with native plants is required.
a Demonstrate how the stabilization shall not otherwise result in a net loss of ecological functions
The resubmitted plan and geotechnical report will likely be reviewed by the city's third party
consultant. The applicant will be required to pay for all costs associated with third party review. A
scope of work will be sent to the third party reviewer upon resubmittal of plans and an explanation of
costs will be routed to you.
3. Variance Needed — Pursuant to FWRC 15.05.050(b)(i), the maximum height of the proposed
bulkhead, or other structural stabilization, is no more than one foot above the elevation of mean
higher high water on tidal waters measured from grade on the waterward side of the bulkhead or
structure. The plans identify the bulkhead at eight feet above MHHW, and therefore, would require a
shoreline variance permit. If you decide to proceed as proposed, please submit a Shoreline Variance
Permit application and fee of $4,187.00. The variance application will need to identify how it meets
the seven criteria listed in FWRC 15.05.160(3). The application materials shall consist of six sets of
plans that include items listed in FWRC 15.05.140.
4. Cultural Resources — The submitted archeological report was prepared for the existing bulkhead that
was constructed in 2006. The report does not identify the proposed work that is now under review.
Pursuant to FWRC 15.050.040(6), a separate site inspection and evaluation by a professional
archaeologist for the proposed scope of work will be necessary prior to any approvals. The evaluation
shall include recommendations for monitoring of potentially disruptive activities, data recovery, and/
or mitigation measures. Monitors from the Puyallup and Muckleshoot Tribes and additional
mitigation may also be required per State Environmental Policy Act (SEPA) procedures.
5. Alternative Solution —As proposed, it is unlikely staff will support the hard armoring approach
detailed in your submittal as its purpose is to protect a landscaped backyard and not a primary
structure on the subject property. Staff would support a soft -shore stabilization solution using a bio-

engineered approach. Soft -shore stabilization will still require a substantial development permit if its
purpose does not meet the exemption criteria mentioned in item # I - The soft -shore solution will also
be required to meet applicable criteria set forth in FWRC 15.05.050(1)(a), and will likely require third
party review.
Closing
The above -referenced items must be addressed before any approval can be issued. The city's Shoreline
Master Program development regulations are codified in FWRC Title 15 and can be accessed online at
http•11www.codepublishing.gomfWA/FederaiWM/. I will also forward your plans to the Muckleshoot and
Puyallup Tribes and the state Department of Archaeology and Historic Preservation for further comment.

Shimer Residence
New Bulkhead
A. Project Location
The project site is located at 2876 SW 300th Place in Federal Way, WA 98023. The property is
situated in the southeast quarter of Section SW 1, Township 21, Range 03 at 47.33497 N Lat.
and-122.37338 W Long.
B. Project Description
The proposed bulkhead is to be ± 22 foot long. It is an addition to the existing bulkhead that was
installed in 2006. The new bulkhead will begin where the existing end on the west front of the
property, it will extend west about ± 22 feet with a 10 foot southward return wall along the
property line.
A recent northwesterly storm's propagated wave erosion left the unarmored portion with a slide
down to the beach level along the property's shoreline. This result of the recent storm has
caused a slump failure on the exposed slope taking debris and existing shrubbery down to the
beach level. The proposed new bulkhead is a long term maintenance item and its purpose is to
protect any future erosion of the unarmored shoreline on this property.
C. Construction Technique & Sequencing
1. Site preparation
A floating silt containment boom will be placed around the project area.
2. on site construction
Bulkhead rocks to be built up from A -man Base rocks imbedded in sound bottom with
subsequent construction of bulkhead rocks to 8' elevation above MHHW. Crushed rock backfill
contained by filter fabric will be installed behind the bulkhead rocks.
3. Equipment used
All construction equipment and materials use in this project would be stationed on the
construction barge. A barge mounted crane will be used to set the new rocks in place.
4. Materials used
2, 3, & 4 man rocks, crushed backfill and filter fabric.
5. Work Corridor
The construction barge is spudded offshore to avoid bottom and shoreline disturbances. All
staging will take place on the barge.
7. Staging Area
The barge will hold all construction materials during the project and all construction debris will
be stored in a container on the barge for subsequent upland disposal.
8. Running of Equipment during Construction
Equipment will be running periodically during the construction as required.
9. Clean - Up
All construction debris will be removed and loaded into containers stored on the barge. It will
then be transported to the contractor's Seattle Yard and disposed of at an approved site.
10. Project Timing
All proposed construction will take place during daylight hours in approved work windows unless
work needs to be coordinated with evening low tides to facilitate construction during approved
work windows.
11. Duration of Construction
On site construction will take about 1 week.

Federal Way, Washington
Dear Mr. and Mrs. Shinier:
At your request, Associated Earth Sciences, Inc. (AESI) has prepared this letter discussing our
opinion regarding recent shoreline erosion at the above -referenced address. This letter was
prepared in accordance with our authorized scope of work and cost estimate dated April 18,
2013. For our use in preparing this letter, we have been provided. With a report, prepared by
Northwest Archaeological Associates, Inc. and dated February 9, 2005, which includes as
Figure 2 an undated site plan and bulkhead detail prepared by Myers Biodynamics, Inc.
(Myers) .
Project Understanding
We understand that a rock bulkhead, with a concrete staircase providing beach access, was
recently constructed across most of the north -to -northwest -facing shoreline at your property.
The shoreline seginent extending across the western portion of the subject property and the
adjacent City of Federal Way right-of-way (301h Avenue SW} to the west does not currently
include a bulkhead. We understand that waves propagated'by a recent northwesterly storm has
eroded the unarmored portion of the subject shoreline, as well as the shoreline segment at the
Federal Way right-of-way, and that a portion of your _property has slid down to beach level,
leaving a scarp near to a gravel path leading to the concrete staircase. Also, the beach access
point at the Federal Way right-of-way has undergone erosion, reducing the. usefulness of this
access point to pedestrians. We understand that you have contacted Waterfront Construction,
Inc. regarding a possible extension of your existing bulkhead and have requested a
geotechnical engineering review of current site conditions and recommendations for
remediation of the distress along the unarmored portion of your shoreline.

Site Observations
We visited the site on April 15, 2013 to observe existing site conditions. The beach materials
near the shoreline consisted of granular soils ranging from sand and pebble gravel to scattered
cobbles and abundant shell fragments. The ground surface rises steeply upward from' the
beach approximately 7 to 8 feet to the backyard of the subject property. An existing rock
bulkhead with a stone staircase provides grade separation from the beach to the yard area along
roughly the eastern two-thirds, of the beachfront. The western portion of the subject
beachfront; along with the beachfront of, the City of Federal Way right-of-way (30d' Avenue
SW) to :the west, does not include a bulkhead. Concrete bulkheads are located at properties to
the east: and west of the subject site and right-of-way.
The soils at the exposed portion of the slope leading up from the beach to the back. yard area
include roughly 3 feet of very dense glacial diamict soils overlain by loose to: medium dense
silty sand. We observed perched groundwater seepage emanating from the contact. 'between the
silty sand and the underlying glacial diamict soils. The lower portion of the slope: i.s, concave
in shape, suggesting an erosion pattern consistent with wave action. This toe erosion extends
across.Jhe City right=of--way and the unarmored portion of the subject property. A pedestrian
beach access point at the Federal Way right-of-way has also undergone erosion, and we
observed cobbles and a wooden post placed down the slope, presumably to facilitate pedestrian
beach access.. The ground surface along the unarmored portion of the slope is sparsely covered
with blackberries and shrubs.
A slump failure has occurred along a portion of the exposed slope segment at the subject
property, with debris and shrubs carried downward to beach level. This failure extends
upward to a gravel pathway at the subject property, with tension cracks observed near an
existing irrigation head. We observed standing water within the slide area on exposed glacial
diamict material. The attached photos illustrate the relationship between the observed toe
-erosion, the slump failure, and the gravel pathway.
Published Data Review
Review of the regional geologic map titled Geologic Map of the Poverty Bay. 7.5-7)71'771ite
Quadrangle, King and Pierce Counties, Washington, by D.B. Booth. H.H. Waldron, and K.G.
Troost (2004) indicates that the area of the subject site is underlain by recessional coarse -
grained lacustrine deposits, along with glacial deposits of pre -Olympia age, which were placed
prior to the advancement of glacial ice over the area during the Fraser Glaciation. Our
interpretation of the sediments observed at the subject site is in general agreement with the
deposits shown on the regional geologic map.
CONCLUSIONS AND RECOMMENDATIONS
From the soil conditions encountered during our reconnaissance, we expect that the existing
bulkhead was originally founded on pre -Olympia -age glacial till sediments. The glacial till
sediments and the recessional soils likely located behind the structure are generally suitable for
support of the backyard landscaping elements, but are susceptible to erosion and piping if
exposed to wave and tidal action. If not mitigated, soil loss would eventually lead to erosion
of the soil behind the existing rock bulkhead. Therefore, the construction of a rock bulkhead
extension to the west of the existing bulkhead is recommended to mitigate the effects of soil
piping from behind the existing bulkhead. To mitigate soil loss originating from the adjacent
City of Federal Way right-of-way, we•recommend that the new rock bulkhead segment extend
across the right-of-way, or that a return wall be constructed which extends southward at least
10 feet along the property. line and notches into the dense pre -Olympia glacial sediments.
It is our opinion that a bulkhead, similar to that previously constructed by Waterfront, :is
necessary to provide protection of the exposed slope, as well as the upland infrastructure (such
as the pathway -anal irrigation. system), on the 2876 SW 300th Place site. In our opinion, the
bulkhead is necessary to provide a stable shore access and to protect property, both private and
public, from shoreline erosion and ground loss. It is also our opinion that a bioengineered
solution, such as using plants or other approved. natural material to stabilize the shore., will not
provide a suitable level of shoreline stabilization and property protection given the relative
closeness of the existing upland infrastructure behind the existing steep bank.
It is our experience that water discharges from fractured irrigation lines have caused shallow
slides at steep sites. We recommend that the existing irrigation system be .shut off until the
recent slide area has been remediated and the proposed rock bulkhead is in place. Also, if the
sprinkler system is to .remain, we recommend that this system include an automatic shut-off
valve at the house to mitigate the flow of water into the slope soils, should a pipe break.
Bulkhead Construction Considerations
The following notes present construction considerations for the proposed rock bulkhead. In
addition, the contractor should confirm that the bulkhead configuration conforms to current
City of Federal Way, specifications. We recommend the following measures to mitigate
potential soil loss from below -and behind the existing rock bulkhead, including
recommendations for a rock bulkhead placed westward of the existing wall.
Rock Bulkhead
We recommend that remediation efforts include construction of a supplemental rock bulkhead
westward of the existing rock bulkhead. Figure 1 shows a detail for the new rock bulkhead
segment. The base of the rock bulkhead should be embedded at least 2 feet into the pre -
Olympia -age glacial diamict sediments underlying the shallow beach sediments. The bulkhead
rocks should be competent rocks with suitable size to bring the bulkhead up to a height that
will reduce the occurrence of overtopping by storm waves. The added rocks should be set
concurrent with a crushed rock backfill zone located behind the rock bulkhead. Construction
of a rock bulkhead in .accordance with these recommendations should provide suitable
protection of the shoreline from erosion. However, rock bulkheads should be considered a
long-term maintenance item.
The following notes present rock bulkhead construction considerations:
A) We recommend the rocks used in the bulkhead construction be placed at a 1H:3V
batter. The rocks should all meet the following weight and dimensional
requirements:
Approximate Weight_(lbs) Average Dimension
2,000/6,000 lbs, graded top/bottom 36 to 54+ inches
These recommendations are for the upper rocks. The average dimension of the
lower rocks should be increased accordingly.
B) Each individual rock should be as nearly rectangular as possible. No stone should
be used that does not extend completely through the bulkhead. The rock material
should be hard, sound, durable, and free of weathered portions, seams, cracks,
excessive porosity, or other defects. The rock density should be at least 160 pounds
per cubic foot (pcf).
Q Rock selection and placement should be such that there will be a minimum of voids.
The rocks should be placed in a manner such that the longitudinal axis of the rock
will be perpendicular to the bulkhead face._ Each rock should be placed so as to
lock into two rocks in the underlying rock course.
D) The bulkhead should be backfilled with 2- to 6-inch crushed rock [WSDOT
Standard Specification 9-13.7(2)] enveloped in a layer of filter fabric, such as
Mirafi Filterweave 403, or equivalent. The crushed rock backfill should have a
minimum thickness of 4 feet between the bulkhead and the retained soil material and
extend to the bottom of the rock bulkhead. The crushed rock backfill should be
placed in lifts to an elevation of approximately 6 inches below the top of each
course of rocks as they are placed until the uppermost course is placed. Any
crushed rock backfill material falling onto the bearing surface of a rock course
should be removed before the setting of the next course.
The crushed rock backfill may be capped with a soil layer provided a geofabric is
used to provide separation of the two materials. We recommend that the soil cap be
limited to 12 inches thick.
E) Any disturbed landscape area above the bulkhead should be planted in accordance
with an approved shoreline revegetation plan.
F) AESI should observe the construction of the rock bulkhead as it progresses to verify
that construction is completed in accordance with these recommendations.

11. Give brief, complete description of your proposal, including the proposed uses and the size of the
project and site. There are several questions later in this checklist that ask you to describe certain
aspects of your proposal. You do not need to repeat those answers on this page.
Proposal: The proposed new bulkhead will be 22 linear feet along the shoreline and an addition to the
existing bulkhead that was installed in 2006. The new bulkhead will begin where the existing ends on
the west front of the property. It will extend west 22 linear feet, with a 10 foot southward return wall
along the property line. A recent northwesterly storm's propogated wave erosion left the unarmored
portion with slides along the property. This result if the recent storm has caused a slump failure on the
exposed slope taking debris and existing shrubbery down to the beach level. The proposed new
bulkhead is a long term maintenance item and its purpose is to protect any future erosion of the
unarmored shoreline and the archeological historical site significance of the recent shell midden
discovery on this property (and any future potential undocumented related sites and the artifacts that
may be there). Please see attached reports : a: Geotechnical report as prepared by Associated Earth

Peter Shimer
2876 SW 3001h Place
Federal Way, WA 98023
RE: Shell midden discovery during a proposed bulkhead installation in the Lakota community
of Federal Way, King County, Washington.
Dear Mr. Shimer,
As you are aware, Northwest Archaeological Associates, Inc. (NWAA) discovered a pre -contact
shell midden prior to a proposed bulkhead installation on your property. This discovery has
been recorded on a Washington State Archaeological Site Inventory Form and submitted to the
Department of Archaeology and Historic Preservation in Olympia. The following sections briefly
summarize the project background and site discovery and concludes with recommendations
related to future ground disturbing activities in or around the archaeological site.
Project Location and Description
NWAA was contracted by Peter Shimer to conduct cultural resources monitoring of bulkhead
installation at 2876 SW 3001h Place in Federal Way, Washington. The project is located along
the shoreline of Puget Sound just east of Dumas Bay in southwest King County in the SW'/ of
the SW% of the NE'/ of the SW% of Section 1, T. 21N., R. 3E (Figure 1). The Department of
Archaeology and Historic Preservation (DAHP) requested archaeological monitoring during
installation of the planned bulkhead in connection with a Shoreline Exemption Permit based on
the proximity to archaeological site 45KI58. The proposed boulder and gravel bulkhead
measures approximately 30 feet x 10 feet x 8 feet. Conditions of the shoreline permit require
that installation of the bulkhead not re-claim any exposed shoreline, therefore the proposed
bulkhead was designed to be installed behind the existing bank (Figure 2).
Pre -Field Research
Prior to archaeological monitoring a records search was conducted at the DAHP in Olympia,
Washington. The focus of the search was to determine the type and proximity of known cultural
resources to the project area. The search revealed that six previous cultural resources studies
have been completed within one -mile of the project (Table 1). The search also revealed that
four archaeological sites have been recorded along the Puget Sound shoreline between Dash
Point and Redondo, however only one is located within a mile of the project. Site 45KI58, a
pre -contact shell midden, is located 0.28 miles southwest. The site was recorded in 1980 by
the University of Washington Office of Public Archaeology during a survey

for a proposed outfall line related to the Lakota Wastewater Treatment plant. The site is
recorded as a partially disturbed shell midden measuring 25 m (82 ft.) east -west by 7 m (23 ft.)
north -south. A single modified cobble and eleven different species of shell were observed
during the discovery and during subsequent archaeological testing (Moura 1980a; 1980b).
Four additional cultural resources studies have been completed within approximately one-half
mile of the project, however no new cultural resources were identified. These projects were
completed in response to widening the Tacoma Loop Highway (Jermann 1976), expansion of
the Lakota Wastewater Treatment Plant (Blukis Onat 1985), construction of a residential
development (Nelson 1998) and improvements to the Lakehaven Utility District (Dampf 2005).
Ethnographer T.T. Waterman (ca. 1920) recorded a number of Native American place names in
and around the Puget Sound region, three of which are within a mile of the project area.
Northeast of the project is Qa'gahwEts meaning "crabapples" for a very small creek near the
community of Buenna, and Kokowi'ltsa meaning "blanket of marmot skins" for Blanket Rock.
Just west of Blanket Rock is Stsoxwa'bats meaning "chokecherry" for a low cliff and numerous
chokecherries in the vicinity (Hilbert et al. 2001).
Expectations
Based on the resource -rich shoreline setting, favorable landform, historic and ethnographic
information, and the proximity to known archaeological sites, the project was considered to have
a moderate to high potential for cultural resources. Pre -contact and ethnohistoric sites were the
most likely to be encountered and would probably represent temporary camps related to
seasonal shellfish harvesting, or other resource procurement activities. These site types are
typically represented by a combination of marine shell deposits, organically -rich -sediments, and
fire -modified rocks (FMR). There was also the potential for Native American burials, or isolated
human remains based on the shoreline setting and proximity to known sites.
Fieldwork
Prior to the fieldwork, NWAA contacted the Puyallup and Muckleshoot Indian Tribes to inform
them of the proposed project (Attachment A). The primary goal of archaeological monitoring
was to identify any cultural materials exposed during subsurface excavations. Installation of

delayed construction until Monday, February 61`'. Mr. James Cross Sr., cultural resources
monitor for the Muckleshoot Indian Tribe, also participated in the fieldwork. Prior to excavation,
Mr. Cross and NWAA monitor Mike Shong identified a shell midden deposit exposed in a wave -
cut beach terrace in front of the property (Figures 3, 4, and 5). The proposed excavation was
halted while the discovery was evaluated. Close inspection of the cultural deposit revealed that
portions of the midden were intact and had potential to provide information related to the
prehistory of the region. Based on the potential significance of the site, the NWAA monitor
requested that no ground disturbing activities be conducted in the immediate vicinity of the site
until boundaries could be defined and a protection plan developed.
Cultural Deposits
The site consists of a 15 cm to 25 cm -thick deposit of shell midden partially exposed along a
wave -eroded beach terrace. The observed midden is approximately 5 cm to 20 cm below the
surface and extends for approximately 6.5 m (21 ft.) before being obscured by slumping
over -bank sediments. Several thin and intermittent lenses of shell midden were observed 5-10
m west of the main deposit before completely disappearing in the profile. Portions of the
cultural deposit appear to be relatively intact based on a distinct layer of shell midden bounded
above and below by organically stained sediments. Approximately 10 FMR were observed in
profile and another 20+ FMR were observed along the beach in front of the midden deposit. All
local species of shellfish are represented along the adjacent shoreline. Two bones were
observed in the profile including an avian scapula and a tarsal fragment from a medium-sized
mammal. Both specimens were observed in the upper midden deposit and could represent
historic intermixing. No flaked or ground -stone tools or lithic debris were observed. The cultural
deposit likely extends toward the east .based on the favorable landform and easy beach access.
This area could contain substantial intact cultural deposits based on the relatively minimal
landscaping and protection from erosion by concrete bulkheads.
Some damage to the site may have occurred within the past several years. Installation of a six-
inch storm drain pipe may have disturbed portions of the site, although the pipe is a
replacement of an older drainage system that followed the same alignment. Additionally, the
City of Federal Way recently constructed a large rock -lined drainage ditch along the 30th Avenue
ROW, just west of the known site, however it is unclear if cultural deposits exist in this area.
Conclusions and Recommendations
The site is likely eligible for listing on the National Register of Historic Places (NRHP) under
criterion (d) that have yielded, or may ,be likely to yield, information important in prehistory or
history (36 CFR 60.4). This eligibility is based on the presence of shellfish and other faunal
remains and the potential for buried cultural features, temporally diagnostic artifacts, and
datable carbon that could address research domains such as chronology, settlement,
subsistence, technology and trade which could contribute to local and regional prehistory.
NWAA recommends that the site be avoided and protected. Avoidance of the site would require
modifications to the existing bulkhead installation plan. One protection alternative would be to
cover the exposed midden deposit with geotextile fabric and install the rock and

Any such modified bulkhead installation should be accompanied by archaeological monitoring.
4
Any proposed excavation into native sediments in the vicinity of the site, or along the shoreline
margin, should be preceded by archaeological testing to define the site boundaries and to
assure intact cultural deposits are not damaged or destroyed. If intact cultural deposits cannot
be avoided, then archaeological testing is recommended to assess the significance, integrity,
and extent of the site and to assist in further protective or mitigation measures if necessary.
The state Archaeological Sites and Resources Act (RCW 27.53) prohibits excavation of an
archaeological site without obtaining a written permit. The DAHP has defined the requirements
for an archaeological excavation and removal permit (chapter 25-48 WAC) and has developed
an application form. Additional information related to Washington State archaeological laws and
permitting can be obtained from the Washington State DAHP 360-586-3083.
I hope this letter adequately addresses the issues related to bulkhead construction in and
around this newly discovered cultural resource. Please feel free to contact me or Chris Miss
with any questions or concerns related to our conclusions and recommendations.
Sincerely,
Michael Shong

SITE DESCRIPTION
Narrative Description:
Temp #: 2876-06-01
T ii• site consists of a 15 cm to cm -thick eposi of shell miUUen partially exposed along a wave -eroded beach terrace just
east of Dumas Bay. The observed midden is approximately 5 cm to 20 cm below the surface and extends for approximately
6.5 m before being obscured by slumping over -bank sediments. Several thin (< 5 cm thick) and intermittent lenses of shell
midden were observed 5 m to 10 m west of the main deposit before completely disappearing in the profile. The cultural
deposit appears relatively intact based on a distinct layer of shell midden bounded above and below by organically rich
sediments.
The landform gradually rises in elevation toward the west so that the beaches in this area are flanked by relatively high
bluffs. The landform east of the observed midden consists of relatively level and low-lying topography occupied by
approximately 10 beach -front homes, most of which have concrete bulkheads protecting the terrace edge. The cultural
deposit likely extends toward the east based_ on the favorable landform and easy beach access. This area could contain
substantial intact cultural deposits based on the relatively minimal landscaping and protection from erosion by concrete
bulkheads.

New Bulkhead of about 32' linear feet along the shoreline.
6b. Describe the purpose of the project and why you want or need to perform it. hel
The proposed new bulkhead is to be a ± 22 foot section of rock bulkhead along the shoreline and an addition to the existing
bulkhead that was installed in 2006. The new bulkhead will begin where the existing ends on the west front of the property, it
will extend west about ± 22 feet with a 10 foot southward return wall along the property line. A recent northwesterly storm's
propogated wave erosion left the unarmored portion with a slide down to the beach level along the property's shoreline. This
result of the recent storm has caused a slump failure on the exposed slope taking debris and existing shrubbery down to the
beach level. The proposed new bulkhead is a long term maintenance item and its purpose is to protect any future erosion of
the unarmored shoreline on this property.

Shimer (bulkhead)
Dear Mr. and Ms. Shimer:
We have received your application for a Department of the Army (DA) permit to construct a
22-foot long section of rock bulkhead above the mean higher high water (MHHW) line of Puget
Sound at Federal Way, Washington. We have reviewed the information that your agent,
Ms. Susan Ulgado, of Waterfront Construction, Incorporated, provided to us pursuant to Section
404 of the Clean Water Act and Section 10 of the Rivers and Harbors Act of 1899. We have
determined that a DA permit is not required for your. proposed work as depicted on the enclosed
drawings dated July 12, 2013. Please note that our determination is also based upon the work
description provided by Ms. Ulgado that material and equipment for the bulkhead would be
delivered to the site via barge, the barge would not be allo -wed to ground out on the beach, that
material and equipment would be placed upland, and the bulkhead would be constructed from
that upland position.
Under Section 10 of the Rivers and Harbors Act of 1899, a Section 10 DA permit is
normally required for work or structures in or affecting navigable waters of the U.S. Although
Puget Sound is a navigable water, a Section 10 DA permit is not required for your project since
no structures would constructed over or under Puget Sound, and work would occur above the
MHHW.
Under Section 404 of the Clean Water Act, a DA permit is normally required for the
discharge of dredged or fill material (e.g., fill, excavation, or mechanized land clearing) into
waters of the U.S., including wetlands and navigable waters of the U.S. As previously
mentioned, Puget Sound is a water of the U.S. However, a Section 404 DA permit is not
required for your project because all fill will be placed above the MHHW.
While a DA permit is not required, local, State, and other Federal requirements may still
apply. For assistance in determining other permit requirements for the proposed project, we
-2-
recommend you contact the Washington State Office of Regulatory Assistance via the internet at
www.ora.wa.gov.
A copy of this letter without enclosures will be furnished to your agent, Ms. Susan Ulgado,
Waterfront Construction, Incorporated, 205 Northeast Northlake Way, Suite 230,
Seattle, Washington 98105. If you have any questions, please contact Ms. Suzanne Anderson
at suzanne.l-anderson@usace.army.mi.l or by phone at (205) 764-3708.

Part 6—Project Description
6a. Briefly summarize the overall project. You can provide more detail in 6b. [tLe�
The applicant proposes to construct an approximately 25-foot long rock retaining wall near the shoreline at the
property and perform minor repairs to the existing rock bulkhead. The rock retaining wall will tie into the existing
rock bulkhead and the new wall will be constructed landward of ordinary high water mark.
6b. Describe the purpose of the project and why you want or need to perform it. net I
The purpose of the project is to prevent ongoing erosion and failure of the bank located along the shoreline.
The bank is prone to failure and is resulting in a loss of property. The retaining is designed to prevent future
property loss. Also. the existing rock bulkhead protects a culturally sensitive shell midden. Continued erosion of
the bank threatens this historic artifact. The proposed retaining wall is also intended to protect the shell midden.

methods and equipment to be used. 1iieip
■ Identify where each element will occur in relation to the nearest waterbody.
■ Indicate which activities are within the 100-year floodplain.
The proposed retaining wall will most likely be constructed from the upland. The construction method will be
determined based on bids received from potential contractors. Regardless of the construction method, the
existing bank, which is located at the QHWM and the edge of the 100-year floodplain will be excavated to the
specified design elevation along the alignment of the proposed wall using a small to medium sized excavator.
The proposed retaining wall will be approximately 6 feet tall and will include a subsurface drain to alleviate
hydrostatic pressure behind the wall. The rock retaining wall will be backfilled with 1-inch drain rock. Material
that is located waterward of the face of the new retaining wall will be excavated and removed from the site. The
excavation will create approximately 100 square feet of beach habitat. The newly created beach will be
passively restored. Upon completion of the new retaining wall, the contractor will restore and enhance the
disturbed upland area. The contractor will install native and appropriate ornamental shrub species in the areas
disturbed by construction. The existing gravel pathways and vegetation will be restored.

8a. Describe how the project is designed to avoid and minimize adverse impacts to the aquatic environment.
hel
❑ Not applicable
The proposed retaining wall is sited landward of the ordinary high water mark, thereby avoiding impacts to the
aquatic environment of Puget Sound. The disturbed vegetation along the shoreline will be restored with native
plant species. The project proposes to create a pocket beach along the shoreline. This pocket beach is
intended to reduce wave energy and promote deposition of fine sediments such and gravels and sand. The
deposition of these fine sediments in intended to create intertidal habitat suitable for forage fish spawning,
specifically, surf smelt. The adjacent City right-of-way is infested with knotweeds and Himalayan blackberry.
These noxious weeds will be removed in the area of the right-of-way that is temporarily disturbed by the
proposed project. Following completion of the project, the applicants will restore the temporarily impacted
vegetation in the right-of-way with native plants. The City will maintain the right-of-way in perpetuity. No
maintenance or monitoring of the right-of-way will be completed by the applicant and no performance standards
in the right-of-way are proposed.

RE: Archaeological evaluation of a proposed bulkhead extension adjacent to 45KI732, Federal Way,
King County, Washington. SWCA Project No. 28076.
Introduction
Property owners Laurel and Peter Shimer requested an archaeological evaluation for proposed
continuation of a shoreline bulkhead and the effects of the bulkhead to site 45KI732, a previously
recorded, Native American shell midden recommended eligible to the National Register of Historic
Places (NRHP). The Shimer's retained SWCA Environmental Consultants to conduct this evaluation.
Project Location and Description
The subject property is at 2876 SW 3001h Place within the Lakota Community of Federal Way, King
County, Washington (Figure 1). The property is located along the marine shoreline in the SW % of the
NE % of the SW % of Section 1, T. 21N., R. 3E, Willamette Meridian. The evaluation included a site
inspection, tribal coordination, site inventory form update and recommendations for monitoring
potentially disruptive activities. The existing 30-foot long rock bulkhead was installed in 2006 to protect
the adjacent terrace and Site 45KI732 from erosion. The proposed project will extend the existing
bulkhead across the remaining unprotected portion of the Shimer property (Figures 2 and 3) providing
additional shoreline protection and to insure that the existing bulkhead does not fail leaving the western
end of 45KI732 unprotected and susceptible to the erosive action of storm waves. The west end of the
proposed bulkhead extension is designed with a turn -back into the bank at the property line to provide
protection from waves coming from the west that could erode behind the bulkhead (Zuvela 2013).
Archaeological Background
Site 45KI732 is a pre -contact shell midden identified and recorded in 2006 prior to installation of the
original Shimer bulkhead (Shong 2006; Shong and Miss 2006). The site consists of a deposit of charcoal -
stained sand and gravel containing whole and crushed marine shell, bone and fire -modified rock that
has been recommended eligible for listing on the NRHP (Shong 2006). In 2011, additional shell midden
deposits associated with 45KI732 were observed approximately 30 m (100 ft.) east during field
reconnaissance for proposed landscaping activities at the Bessler property located at 2854 SW 300th
Place (Shong and Miss 2011). Prior to field reconnaissance the shoreline side of the Bessler property

2 Archaeological Evaluation of a Proposed Bulkhead Extension Adjacent to 45KI732
had been graded exposing the underlying soils and shell midden deposits associated with 45KI732. The
Department of Archaeology and Historic Preservation (DAHP) requested that a damage assessment of
45KI732 be conducted within the Bessler property to document any alteration of the site caused by
construction and landscaping activities. As part of the damage assessment, SWCA excavated 12 auger
probes and two test excavation units under a DAHP-issued archaeological excavation permit to
determine the extent and integrity of archaeological deposits with the Bessler Property. A radiocarbon
sample collected from the site was analyzed producing a conventional radiocarbon date of 660 ± 30 BP
(years Before Present). SWCA recommended that geotextile fabric be placed over exposed and intact
archaeological deposits and that the excavation of two proposed patio nooks in areas containing heavily
disturbed shell midden be monitored by an archaeologist (Shong and Miss 2012). SWCA also prepared
an update to the State of Washington Archaeological Inventory Form for 45KI732 (Shong 2012).
Tribal Coordination
Prior to field reconnaissance, SWCA contacted the Puyallup Tribe and the Muckleshoot Tribe to inform
them of the proposed fieldwork. Puyallup Tribe archaeologist Brandon Reynon visited the site during
fieldwork.
Methods
A site visit was conducted on December 5, 2013 by SWCA Archaeologist Mike Shong. Property owner
Laurel Shimer was on site to answer questions related to shoreline erosion and the location, extent, and
need for the proposed bulkhead extension. Puyallup Tribe archaeologist Brandon Reynon was on site
during field reconnaissance and viewed the recent erosion and location of the proposed bulkhead. The
goal of the investigation was to determine the extent of shoreline erosion since 2006 and to determine
if archaeological deposits associated with 45KI732 were present within the proposed bulkhead
footprint, or would be affected by continued erosion. The SWCA archaeologist compared photographs
taken in 2006 to current conditions. A 50 ft. tape was used to measure the distance of the proposed
bulkhead along the shoreline to accurately gauge the location of the proposed bulkhead. Shoreline
exposures and recently slumped sediments were examined for the presence of archaeological deposits
and materials. Additionally, three soil profiles within and just outside the proposed footprint were
manually exposed to investigate the subsurface constituents. Documentation included recording notes
and observations on standard forms and photo -documenting current conditions within the proposed
bulkhead footprint.
Results
No archaeological materials associated with 45KI732, or cultural resources of any kind were observed
within the proposed bulkhead continuation footprint. Based on photographs taken in 2006, significant
shoreline erosion has occurred immediately west of the existing rock bulkhead. A portion of the terrace
margin within the proposed bulkhead footprint measuring approximately 13 ft. long (east west) and 8 ft.
wide (north south) has slumped onto the beach within the past year (Figures 4, 5, 6 and 7). The slumped
terrace segment was densely vegetated, however the root system ultimately did little to anchor the
soils, or protect the terrace from erosion. The slumped segment did, however, provide good exposures
in which to view the upper Holocene sediments for the presence of cultural resources (Figures 8, 9 and
10). The wave -eroded shoreline margin immediately west of the Shimer property (City of Federal Way
30th Avenue Right -of -Way) was also inspected for the presence of archaeological materials, although
none were observed.

Several displaced fire -modified rocks, the byproduct of Native American cooking/heating activities, were
observed along the beach in front of the Shimer property. These artifacts likely originated from erosion
to archaeological deposits associated with 45KI732, however their context and archaeological integrity
have been lost.
Conclusions and Recommendations
No archaeological materials associated with 45KI732, or cultural resources of any kind were observed
within the proposed bulkhead continuation footprint. While no archaeological deposits or materials
were observed, erosional processes (wave scour) was observed adjacent to and behind the west end of
the existing rock bulkhead. Overtime, these effects could undermine the intact soils behind the
bulkhead damaging archaeological deposits associated with 45KI732. A continuation of the existing
bulkhead as proposed by the property owners would ultimately protect 45KI732 from near -future
erosional damage. Ground disturbing actions associated with any potential bulkhead construction
should be monitored by an archaeologist to insure that inadvertent discovery of archaeological
materials or human remains are identified and appropriately treated. Prior to any potential ground
disturbing activities, a monitoring and discovery plan should be developed and submitted to DAHP and
affected Tribes for review. Based on the observations and data included in this report, a site form
update to 45KI732 has been completed and is attached (Attachment A).
Please do not hesitate to contact myself or Christian Miss with any questions regarding site 45KI732, or
safeguarding the heritage resources on your property.

SITE DESCRIPTION Temp #: 2876-06-01
Narrative Description:
The site consists of a 15 cm to 25 cm -thick deposit of shell midden partially exposed along a wave -eroded beach terrace just
east of Dumas Bay. The observed midden is approximately 5 cm to 20 cm below the surface and extends for approximately
6.5 m before being obscured by slumping over -bank sediments. Several thin (< 5 cm thick) and intermittent lenses of shell
midden were observed 5 m to 10 m west of the main deposit before completely disappearing in the profile. The cultural
deposit appears relatively intact based on a distinct layer of shell midden bounded above and below by organically rich
sediments.
The landfarm gradually rises in elevation toward the west so that the beaches in this area are flanked by relatively high
bluffs. The landform east of the observed midden consists of relatively level and low-lying topography occupied by
approximately 10 beach -front homes, most of which have concrete bulkheads protecting the terrace edge. The cultural
deposit likely extends toward the east based on the favorable landform and easy beach access. This area could contain
substantial intact cultural deposits based on the relatively minimal landscaping and protection from erosion by concrete
bulkheads.

CULTURAL MATERIALS & FEATURES
Narrative Description:
Over 10 fire -modified rocks (FMR) were observed In profile and another 20+ FMR were observed along the beach in front of
the midden deposit. All local species of shellfish are represented along the adjacent shoreline. Two faunal bones were
observed in the profile including an avian scapula and a tarsal fragment from a medium-sized mammal. Both specimens
were observed in the upper midden deposit and could represent historic intermixing. No flaked or ground -stone tools or
Iithic debris were observed.

Project Background:
NWAA/SWCA was contracted by Michelle and Robert Bessler to conduct archaeological monitoring of
proposed landscaping activities at 2854 SW 300th Place in Federal Way, Washington. The DAHP
requested an archaeological assessment of the property prior to landscaping, (or) archaeological
monitoring during ground -disturbing activities. This request was based on the proximity to site 45KI732
located approximately 100 feet southwest of the Bessler property. The original site form states that the
site likely continues east (toward the Bessler property) along a relatively level, low-lying terrace and that
this area and could contain substantial intact cultural deposits based on the relatively minimal
landscaping and protection from erosion by concrete bulkheads.
Observations:
Prior to proposed landscaping and archaeological monitoring, the northern (shoreline) margin of the
property had been stripped of sod exposing the underlying soils composed of fill and pre -contact shell
midden. Additionally, mechanical excavations associated with construction of the new house exposed
shell midden in profile along the northeastern property margin. The shell midden exposed in profile
consisted of black, charcoal -rich fine to coarse sand with abundant marine shell and fire -modified rock
(FMR). Cursory inspection of the exposed profile revealed intact cultural deposits and a possible fire
hearth feature near the contact with the underlying soil B-horizon composed of a reddish -brown fine- to
medium grained sand. The midden had a maximum thickness of 35 cm, but thinned gradually toward the
south as it transitioned into a soil A -horizon with less charcoal and shell content. Sparse shell flecks and
FMR were observed in profile approximately 30 m south of the shoreline bulkhead. Several faunal bone
and lithic flakes derived from medium- to fine-grained volcanic material were observed within displaced
midden spoil in the northeast corner of the property. The loose, surface midden in this area appeared to
have been mechanically pushed over the terrace edge, likely during grading for the house foundation.

Sod removal prior to archaeological monitoring exposed dark, grayish- brown charcoal -stained sand with
sparse shell along the terrace edge. Mixed fill, soil A -horizon material, and loose shell midden comprised
much of the sloping landform surface between the terrace edge and the shoreline bulkhead. A small trench
measuring approximately 50 x 150 cm was mechanically excavated at a proposed patio -nook landscaping
feature near the shoreline to investigate the sub -surface sediments. Then trench revealed a 10-20 cm thick
deposit of shell midden sloping toward the shoreline (see attached profile). The midden in the southern half of
the trench profile contained very few shells and appeared to be re -worked to some degree, while the northern
(down slope) half of the profile contained relatively abundant charcoal, shell and FMR. The cultural deposits
capped an intact soil B-horizon composed of light yellowish -brown fine- to medium -grained sand. A 30 cm
diameter shovel probe excavated just north of the trench and approximately 1.5 m south of the bulkhead
revealed approximately 30 cm of rounded beach gravels overlying shell midden. The shell midden observed
in the shovel probe was not investigated and its thickness and integrity remain unknown.
A second trench was excavated in front of the newly constructed Bessler residence and just south of the
exposed surface midden. This trench revealed heavily mottled loamy sand and gravel fill to a depth of
approximately 120 cm. No archaeological deposits or materials were observed in this trench, however several
fragments of lumber and concrete drain pipe were encountered. The property owner stated that a septic
system associated with the former house may have been removed from this vicinity. The presence of concrete
pipe fragments and slightly odiferous sediments tends to collaborates this belief.
Based on the presence of shellfish and other faunal remains and the potential for buried cultural features,
temporally diagnostic artifacts, and datable carbon, site 45KI732 is likely eligible for listing on the National
Register of Historic Places under criterion (d).
NWAA/SWCA recommended to the property owner that the archaeological deposits be avoided and protected
through modifications to their existing landscape design. NWAA/SWCA also recommended the following
actions to protect the exposed archaeological deposits:
* No further ground disturbance to existing sediments should be conducted within 30 m of the shoreline.
* Areas with surface -exposed shell midden should be covered with geotextile fabric and capped with fill.
* The shell midden exposed in profile along the northeast edge of the property should be covered with
geotextile fabric and protected from further erosion with a rock or concrete barrier.

Observation:
In 2011, private property owners Michele and Robert Bessler constructed a new residence on site 45KI732, a
pre -contact shell midden, located along the shoreline of Puget Sound east of Dumas Bay. Newly exposed
shell midden was observed during field reconnaissance for proposed landscaping activities at the Bessler
property (Shong and Miss 2011). SWCA subsequently recommended that the archaeological deposits be
avoided and protected through modifications to proposed landscape designs. DAHP, in a letter dated
November 30, 2011, stipulated that:
*a damage assessment of 45KI732, within the Bessler property, should be conducted to document any
alteration of the site caused by recent construction;
"the damage assessment and any further ground disturbing activities must be conducted under an
archaeological excavation permit;
*archaeological deposits within the Bessler property should be covered with geotechnical fabric and fill;
*the placement of geotechnical fabric and fill should be monitored by a professional archaeologist;
*monitoring should be conducted under the auspices of a cultural resources monitoring and discovery plan;
*a charcoal sample should be collected from an intact archaeological context and submitted to a
professional laboratory for radiocarbon dating;
*a cultural resources management plan should be developed that includes provisions for responding to an
inadvertent discovery of cultural materials or human remains.
SWCA was retained by Michele and Robert Bessler to complete these tasks. SWCA applied for, and was
co -issued, Emergency Archaeological Excavation Permit No. 2012-08. In March 2012, SWCA conducted a
damage assessment of the Bessler property using a combination of auger probes and test excavation units
(Shong and Miss 2012a). In May 2012, SWCA monitored the placement of geotechnical fabric and fill; and
monitored patio excavations within disturbed portions of the site (Shong and Miss 2012b).

Damage Assessment
SWCA excavated 12 auger probes (10 cm diameter) and two test excavation units (50 cm2). Auger probes
were excavated in 20 cm arbitrary levels and test units in 10 cm arbitrary levels. All excavated sediments were
passed through 1/4-inch mesh screen. The results of the damage assessment suggested that archaeological
deposits within the Bessler property are moderately to heavy disturbed; however, some areas of the property
contain intact deposits (Shong and Miss 2012a). Based on the presence of older fills, heavy mottling of native
sediments and the presence of historic materials, it appears that the site (within the Bessler property) was
significantly disturbed prior to construction of the Bessler residence.
Auger Probe Investigations
The results of auguring indicate the best preserved archaeological deposits are in the northeast corner of the
property (terrace edge) in the vicinity of AH 1, and to a lesser degree, AH 2. This area contained charcoal -rich
shell midden overlying a reddish -brown soil-B-horizon. Some areas in the northwest corner of the property, in
the vicinity of AH 5, AH 7 and AH 12, also appeared to be relatively intact, although noanthropomorphically
-stained sediments or cultural materials were observed in AH 12. A layer of fill (20-60 cm thick) overlies shell
midden ranging between 10-30 cm thick in AH 5 and AH 7, respectively. Auger probes excavated just south
and east of the boathouse contained thick fill and heavily disturbed/displaced cultural deposits. These probes
(AH 8, 10 and 11) suggest that a natural topographic low was filled with local sediments (sand, midden and
beach gravel) excavated during construction of the adjacent boathouse. This buried topographic low likely
represents a former creek channel that is partially day -lighted along the western margin of the Bessler property
before entering a culvert that empties into Puget Sound just east of the boathouse. Fragments of earthenware
ceramics and a machine -cut square nail were encountered between 100-150 cmbs in AH 8, suggesting that
significant historic materials and archaeological deposits may be present in this former ravine.
Patio Nook Investigations
Test excavation units placed at two proposed patio footprints, encountered heavily disturbed and displaced
archaeological deposits. Cultural material was dominated by faunal remains and FMR. Bivalve remains
included littleneck clam, butter clam, horse clam, cockle, as well as a few mussels, barnacles, moon snails and
sea snails. Several mammal and bird bones were also encountered including sawn cow bones and a few
unburned/unmodified deer -sized bones.
Test Unit 1, located in the smaller, eastern patio nook footprint, contained a late 19th century historic
component intermixed within displaced, terrace -slumped shell midden below approximately 60 cmbs. Historic
materials included machine -cut square nails, lantern mantel glass, olive-green bottle glass, a hand -tooled
liquor flask fragment, a .22 caliber shell casing and sawn mammal bone. The lower historic component may
represent an early Euroamerican, or possibly ethno-historic occupation of the Lakota Community. SWCA
recommended that excavations in this area be restricted to the upper 50 cm to preserve the underlying historic
component (Shong and Miss 2012a).
Test Unit 2, located within the larger (central) proposed patio nook area, was particularly disturbed and
retained no physical integrity or scientific data potential.
Monitored Excavations
In May 2012, SWCA archaeologists monitored the placement of geotechnical fabric and fill over the northern
14 m (46 ft.) of the Bessler property. As expected, both patio excavations resulted in the removal of heavily
disturbed cultural deposits. These cultural matrices generally consisted of heavily re -worked (mixed) and
displaced anthropogenic sediments ranging from lightly organic sand and gravel to moderately organic sand
with sparse shell and FMR.

STATE OF WASHINGTON ARCHAEOLOGICAL INVENTORY FORM
ADDENDUM / UPDATE State Number: 45KI732
The central patio excavation measured 7 x 4 m and 1.5 m deep and consisted of lightly organic sand and
gravel with very few shells and FMR overlying an intermittent B/C-horizon. A profile of the central patio
excavation shows two buried concrete drain pipes aligned north -south. The A -horizon spanning the profile and
shows no evidence of being truncated, suggesting post depositional displacement of the overlying organic
sediments i.e., the A -horizon post-dates the installation of the concrete drain pipes ca. 1920-1950. The
B/C-horizon, composed of yellowish -brown to grayish -brown sand, is intermittent across the profile. The lack of
an intact soil B-horizon is further evidence that intact cultural deposits were stripped from the terrace margin in
the central patio nook vicinity and covered over with displaced/re-worked anthropogenic sediments.
The eastern patio excavation measured 3 m2 and 60 cm deep and contained relatively organically -rich
(charcoal -stained) sediments, but still significantly disturbed and displaced based on the relatively loose
compaction and lack of soil development. The spoil from the eastern patio excavation may have been recently
deposited in this area -possibly during construction of the Bessler residence. Anthropogenic sediments from
both patio excavations sharply contrast with intact cultural deposits documented along the eastern property
margin composed of black, charcoal -rich sand with abundant shell and FMR overlying an intact, reddish -brown
soil B-horizon.
Sample sifting of a combined 1.5 m3 of patio excavation spoil produced a small amount of cultural material. In
addition to a relatively small amount of shell, bone, FMR and late -historic material, one surf -polished jasper
flake was recovered from the central patio excavation (0.5 m3 sampled) and five flaked -stone artifacts were
recovered from the eastern patio excavation (1 m3 sampled) including one edge -modified cobble, one
edge -modified CCS flake, a CCS tertiary flake, a silicified wood flake and a spit -jasper pebble (Shong and Miss
2012b). No formed tools or temporally diagnostic artifacts were recovered. As stipulated in the archaeological
excavation permit, the cultural material collected during State -permitted excavations will be given the property
owners Michele and Robert Bessler for curation and all documents will be curated at the Burke Museum in
Seattle.
Cultural resources Management Plan
A cultural resources management plan prepared for the Bessler property details protection and management
guidelines for site 45KI732 within their property. The document identifies areas of the property that contain, or
may contain, intact or disturbed archaeological materials and includes provisions for responding to an
inadvertent discovery of cultural materials or human remains, should such materials be uncovered during
future ground -disturbing activities.
Additional Archaeological Resources
During the course of fieldwork at the Bessler property, the property owner to the east (Chuck Larson)
approached SWCA archaeologists and shared some of his beach finds. Mr. Larson is aware his property
occupies a pre -contact shell midden and has collected flaked -stone artifacts from the gravel beach in front his
property. Mr. Larson produced a bucket containing several dozen fine-grained volcanic (basalt) flakes, cores
and edge -modified cobbles. Somewhat surprisingly, no CCS materials or temporally diagnostic artifacts were
included in Mr. Larson's assemblage. Based on the soil profile along the Bessler's eastern property margin
(Larson's western property margin), the Larson property appears to contain the best preserved archaeological
deposits remaining at 45KI732.
Radiocarbon Analysis
A small, carbonized sample of unidentified soft wood (containing outer growth rings with phloem) was collected
from an intact archaeological context along the eastern property margin and submitted to Beta Analytic for
analysis. The sample was analyzed using the Accelerator Mass Spectrometry (AMS) process (Beta No.
321933). The analysis produced a t 1 sigma (68% probability) conventional radiocarbon date of 660 f 30 BP;
with 2 sigma (95% probability) calibrated radiocarbon intercepts between Cal AD 1280 to 1320 (Cal BP 670 to
630) and Cal AD 1350 to 1390 (Cal BP 600 to 560).

Observation:
Project Background:
in December 2013 property owners Laurel and Peter Shimer requested an archaeological evaluation for
a proposed continuation of a shoreline bulkhead and the potential effects of the bulkhead to site 45KI732,
a previously recorded, Native American shell midden recommended eligible to the National Register of
Historic Places (NRHP) (Shong and Miss 2006, 2011, 2012). The Shimer's retained SWCA
Environmental Consultants to conduct the evaluation.
The evaluation included a site inspection, tribal coordination and recommendations for monitoring
potentially disruptive activities if the City of Federal Way aproves the bulkhead extension. The existing
30-foot long rock bulkhead was installed in 2006 to protect the adjacent terrace and Site 45KI732 from
erosion (Shong 2006; Shong and Miss 2006). The proposed project will extend the existing bulkhead
across the remaining unprotected portion of the Shimer property providing additional shoreline protection
needed to ensure that the existing bulkhead does not fail leaving the western end of 45KI732 unprotected
and susceptible to the erosive action of storm waves. A site visit was conducted on December 5, 2013
by SWCA archaeologist Mike Shong. Mr. Shong was joined by Puyallup Tribe archaeologist Brandon
Reynon. The goal of the investigation was to determine the extent of shoreline erosion to the Shimer
property since 2006 and to determine if archaeological deposits associated with 45KI732 were present
within the proposed bulkhead footprint, or would be affected by continued erosion.
No archaeological materials associated with 45KI732, or cultural resources of any kind were observed
within the proposed Shimer bulkhead continuation footprint. Based on photographs taken in 2006,
significant shoreline erosion has occurred immediately west of the existing rock bulkhead. A portion of
the terrace margin within the proposed bulkhead footprint measuring approximately 13 ft. long (east
west) and 8 ft. wide (north south) has slumped onto the beach within the past year. The slumped
segment provided good exposures in which to view the upper Holocene sediments for the presence of
cultural resources. The wave -eroded shoreline margin immediately west of the Shimer property (City of
Federal Way 30th Avenue Right -of -Way) was also inspected for the presence of archaeological
materials, although none were observed. Several displaced fire -modified rocks were observed along the
beach in front of the Shimer property, however their context and archaeological integrity have been lost.

45KI732
While no archaeological deposits or materials were observed, erosional processes (wave scour) was observed
adjacent to and behind the west end of the existing rock bulkhead. Overtime, these effects could undermine
the intact soils behind the bulkhead damaging archaeological deposits associated with 45KI732. A
continuation of the existing bulkhead as proposed by the property owners would ultimately protect 45KI732
from near -future erosional damage. SWCA recommeded that any ground disturbing actions associated with
the potential bulkhead extension should be monitored by an archaeologist to insure that inadvertent discovery
of archaeological materials or human remains are identified and appropriately treated. SWCA also
recommended that prior to any potential ground disturbing activities, a monitoring and discovery plan should
be developed and submitted to DAHP and affected Native American tribes for review.
Based on field observations collected December 2013, the western site boundary was adjusted from the
previously updated boundary of August 2012. As part of this update, comparative photographs of the Bessler
property in 2006 and 2013 have been included.
Additionally, since the last site update was completed in 2012, SWCA archaeologist Mike Shong was invited to
view the Larson's artifact collection from the beach in front of 45KI732. Contrary to what was known and
reported in 2012 (Larson collection composed of several dozen fine-grained volcanic flakes, cores and
edge -modified cobbles), Mr. Larson shared some of his other beach finds from 45KI732 and local anecdotal
accounts of cultural resources found in the area. Mr. Larson produced a tray of several dozen CCS artifacts,
primarly red jasper edge -modified flakes, scrapers, bifaces and several triangular and contracting stem -form
projectile points. A small nephrite adze blade, a sky-blue glass trade bead (chief bead) and a basalt
lanceolate (Cascade -style) dart point were also part of the Larson collection. To date, Mr. Larson has been
reluctant to allow photo documentation of his collection, however the overall collection is very similar to private
collections from Quartermaster Harbor six miles northwest (see Demuth et al. 2006:11-16).
