Critical Areas Determination
Applicant: Pat Walker Determination #: CA-95-83
Project Name: Permit Number:
Site Location: 16208 74th Pl. W. Property Tax Acct #: 5131-000-06
Project Description:
non -project specific
A site inspection of the property has revealed a steep slope which may be as steep or steeper than
40% and there is more than 20 feet of vertical elevation gain. ,
Based on the above findings, it is determined that there is potential for critical areas on or
adjacent to the site. A Critical Areas Study is required to delineate the boundaries of the
potential critical area, its buffers and setbacks.
The study will contain the following: A licensed surveyor must create a topographic map of the
site which indicates all areas which slope 40% or more and have a vertical gain of 20 feet or
more within the 40% slopes. The map must also show the top of slope and location of the buffer
and setback associated with the steep slope.
If the property owner wishes to apply for a specific development permit which they feel
would not impact the Critical Areas located on the site, they may submit their proposal to
the Planning Department for review. If the Planning Department finds that the proposed
development permit will not adversely impact a Critical Area or its buffers, a conditional
waiver may be issued on a project by project basis.

RE: Slope Stability Consultation
Dear Mr. & Mrs. L,ehp., F
GARY HAAKENSON
MAYOR
In response to your Associated Earth Sciences report dated 3/15/01 regarding a landslide that
occurred on or near property you own at 16202 72°a Avenue West; City consultants have
investigated the noted slope failure and a copy of the Landau Associates report dated 4/19/0.1 is
attached.
After reviewing this report and the information you previously supplied me, it is my
determination as Building Official, that no further investigation or mandatory slope mitigation
(including temporary or permanent slope protection) appear to be warranted at this time and
therefore will not be imposed by me for any of the upslope or downslope properties.
Meadowdale property owners have a general awareness of landslide hazards and risks associated
with steep slope property. Property owners generally understand the landslide hazard risks
inherent with private property in or near this area. It continues to be important for such
properties to take measures to best manage such risks, including but not limited to, utilizing
professional-•---geoteciii ical- -exp`eftise" to -'further investigate and evaluate _the landslide' risks,
monitoring slope . movement, implementing slope- and/or drainage improvements, developing
recommendations for site specific mitigating measures, etc.
Should there be a change in the future conditions or any new information develops I would
welcome the impute and will review the matter in light of any new information provided me.
Thank you,

At your request, we conducted a limited review of slope stability and risk issues at 16202 72d
Avenue West (subject property) and several properties to the west of this property, including the Walker
property and the southernmost property within the Lorian Woods subdivision. As part of our review, we
visited the site on April 4, 2001 and looked at a letter to Phillip Lehn (owner of the subject property)
prepared by Associated Earth Sciences, Inc. (AESI), dated March 15, 2001, and a letter to the City of
Edmonds prepared by AESI, dated March 16, 2001. We did not review the March 6, 2001 digital images
referenced in the letter to Mr. Lehn or the results of a March 12, 2001 reconnaissance reportedly
conducted by Adapt Engineering, as mentioned in AESI's March 15, 2001 letter.
During our site visit, we observed the area of the February 13, 1998 landslide referenced in the
AESI March 15, 2001 letter. We also reviewed letters prepared by Landau Associates in 1998 for the
of-Edmonds'pertaining to this landslide. The 1998 landslide area remaiiilnslargely overgrown. A
near -vertical exposure of sandy soil is present near the headscarp area as present in 1998 and noted in the
March 15, 2001 AESI letter. In addition, we noticed a zone of hard, gray, fractured, silt and clay exposed
further downslope below the zone of exposed sandy soil. Large chunks of silt and clay (cobble to boulder
size) have spalled off of this near -vertical soil exposure. This silt and clay exposure is evident from the
property below, but is not visible from the subject property at the top of the slope.
At the top of the west -facing slope near the west side of the subject property, we observed a small
ground crack in sandy soil north of the 1998 landslide area. The crack appeared to be relatively recent
(probably within the last several months). We suspect that the crack may have been more evident when
observed by others in February, as it was partially obscured at the time of our visit (probably due to
weather and rain influence on the sandy soil). The observed ground crack was within or adjacent to the
top of the headscarp of the overall slope. This headscarp could have been associated with older

movement at this location rather than recent movement associated with the small ground crack.
Vegetation obscured the extent of ground cracking or movement, if any, on the property immediately to
the north of the subject property. The 24- to 36-inch headscarp located to the south of the observed
ground crack referenced in the AESI letter was not as obvious to us.
We agree that similar topographical and geological factors that were involved with the 1998
landslide are likely present in the area of recently observed movement and ground cracking. In fact,
similar conditions likely exist along most of this bluff extending to the north and south of this property,
and not specifically just at the observed location. We agree that there is risk of future landsliding on this
bluff. This risk existed before the observed ground cracking. In our opinion, the observed ground
cracking occurring near the location of an existing landslide headscarp does not necessarily represent a
new risk. The ground cracking is simply the current, visible evidence of a long-term slope risk that is
present at this location. We would expect to see various indications of slope movement at different
locations along this slope over time. Because there is currently visible evidence of some movement at
this particular location, that could imply that this location may be more likely to be involved in future
slope movement than adjacent areas where no movement is currently evident.
We concur that it is appropriate to share the information regarding recently observed slope
conditions with the neighboring residents. By AESI copying the March 16, 2001 letter to a number of
surrounding residents, this notification may have already occurred. We understand that the toe of the
February 13, 1998 landslide came onto property owned by Mrs. Walker. It is not clear to us whether this
property was included in the notification of nearby residents, but probably should be.
Since the subject property and properties to the west are all within the City of Edmonds'
"Meadowdale Earth Subsidence and Landslide Hazard Area" as defined in Ordinance #2661, we assume
that all of the affected residents are fully_ aware of the: landslide_risk inherent with,the. property -in .this .area.
In particular, property that has been developed since the "Meadowdale Ordinance" has been in effect have
all required specific geotechnical studies and the identification of landslide hazard and risk as a part of the
permitting and development process for newer residences. We are aware that geotechnical studies
associated with the development within the Lorian Woods subdivision at the toe of the subject slope have
identified this slope as a landslide hazard.
In our opinion, it is difficult to determine whether the ground crack present near the existing,
oversteepened headscarp location would progress to result in only localized sloughing and slope
movement at this location, or progress to a larger slope movement similar to the 1998 landslide. The
recent notification of current conditions by AESI to the neighboring property owners and the general
awareness of landslide hazards and risks that have been previously communicated to the property owners
is important. Since the slope is located on private property, it would appear that it is the responsibility of

the individual property owners to understand the landslide risks inherent with property in this area and
take measures to best manage these risks. Measures that could be taken by the property owners include,
but are not limited to, monitoring slope movement, implementing slope and/or drainage improvements,
and retaining a consultant to further investigate and evaluate the landslide risks and develop
recommendations for site -specific mitigating measures that could be implemented.
We appreciate this opportunity to be of service to the City of Edmonds. Please call us if you have
any questions regarding this letter or if we may of further assistance.

March 15, 2001 AESI letter. In addition, we noticed a zone of hard, gray, fractured, silt and clay exposed
further downslope below the zone of exposed sandy soil. Large chunks of silt and clay (cobble to boulder
size) have spalled off of this near -vertical soil exposure. This silt and clay exposure is evident from the
property below, but is not visible from the subject property at the top of the slope.
At the top of the west -facing slope near the west side, of the subject property, we observed a small
ground crack in sandy soil north of the 1998 landslide area. The crack appeared to be relatively recent
(probably within the last several months). We suspect that the crack may have been more evident when
observed by others in February, as it was partially obscured at the time of our visit (probably due to
weather and rain influence on the sandy soil). The observed ground crack was within or adjacent to the
top of the headscarp of the overall slope. This headscarp could have been associated with older

movement at this location rather than recent movement associated with the small ground crack.
Vegetation obscured the extent of ground cracking or movement, if any, on the property immediately to
the north of the subject property. The 24- to 36-inch headscarp located to the south of the observed
ground crack referenced in the AESI letter was not as obvious to us.
We agree that similar topographical and geological factors that were involved with the 1998
landslide are likely present in the area of recently observed movement and ground cracking. In fact,
similar conditions likely exist along most of this bluff extending to the north and south of this property,
and not specifically just at the observed location. We agree that there is risk of future landsliding on this
bluff. This risk existed before the observed ground cracking. In our opinion, the observed ground
cracking occurring near the location of an existing landslide headscarp does not necessarily represent a
new risk. The ground cracking is simply the current, visible evidence of a long-term slope risk that is
present at this location. We would expect to see various indications of slope movement at different
locations along this slope over time. Because there is currently visible evidence of some movement at
this particular location, that could imply that this location may be more likely to be involved in future
slope movement than adjacent areas where no movement is currently evident.
We concur that it is appropriate to share the information regarding recently observed slope
conditions with the neighboring residents. By AESI copying the March 16, 2001 letter to a number of
surrounding residents, this notification may have already occurred. We understand that the toe of the
February 13, 1998 landslide came onto property owned by Mrs. Walker. It is not clear to us whether this
property was included in the notification of nearby residents, but probably should be.
Since the subject property and properties. to the west are all within the City of Edmonds'
"Meadowdale Earth Subsidence and Landslide Hazard Area" as defined in Ordinance #2661, we assume
_,_ •. - , .:: rthat all of the affected residents are fully aware. of the landslide risk. inherent with_the.property in this. area.
In particular, property that has been developed since the "Meadowdale Ordinance" has been in effect have
all required specific geotechnical studies and the identification of landslide hazard and risk as a part of the
permitting and development process for newer residences. We are aware that geotechnical studies
associated with the development within the Lorian Woods subdivision at the toe of the subject slope have
identified this slope as a landslide hazard.
In our opinion, it is difficult to determine whether the ground crack present near the existing,
oversteepened headscarp location would progress to result in only localized sloughing and slope
movement at this location, or progress to a larger slope movement similar to the 1998 landslide. The
recent notification of current conditions by AESI to the neighboring property owners and the general
awareness of landslide hazards and risks that have been previously communicated to the property owners
is important. Since the slope is located on private property, it would appear that it is the responsibility of

the individual property owners to understand the landslide risks inherent with property in this area and
take measures to best manage these risks. Measures that could be taken by the property owners include,
but are not limited to, monitoring slope movement, implementing slope and/or drainage improvements,
and retaining a consultant to further investigate and evaluate the landslide risks and develop
recommendations for site -specific mitigating measures that could be implemented.

Dear Mr. Lehn:

/GZo 9 era .r
At your request, we are providing the following summary of a limited slope reconnaissance of
your property at 16202 72nd Avenue West in Edmonds, Washington. Our slope reconnaissance
was performed on February 13, 2001.
The subject property consisted of approximately 1.56 acres of developed residential property
bordered by a steeply sloping hillside. to the west. The existing Lehn residence is located in the
northem .portion of the site.
The steep hillside sloped down, toward the west, at an average slope inclination on the order of
1H:1V (Horizontal:Vertical). Total vertical relief of the slope was approximately 120 feet. A
surficial' landslide, which involved- the entire height of the slope, was reported to have occurred
on February 13, 1998.. The slide occurred below the southwest corner of the subject property and
consisted of rapidly moving mud. and debris.. The slide debris moved over the entire height of
the hill and caused damage to the private property below. 'Damage to the upslope property
consisted of loss of a portion of the upper slope and damage to a former gazebo. During our
slope reconnaissance, we noted that the majority of the slide debris had been overgrown with
dense ground cover withthe exception of the headscarp-area, which consisted of near vertical,
bare sandy soils. _
During our reconnaissance, we also noted the presence of an approximately 40-foot-long; 24- to
36-inch headscarp below the northwestern corner of the subject property. This headscarp was
approximately 70 feet north of. the 1998 landslide area. The crack was visible on the subject
property (Lehn property) through landscaped areas west of an existing rockery. The scarp was .

inferred to' continue onto the neighboring property .to the north but was obscured by heavy
ground cover. The scarp appeared to be the result of recent earth movement on the slope.
Following our site visit, we also reviewed a total of seven digital images recorded by Mr. Lehn
on March 6, 2001. These images illustrate conditions at the site shortly after the February 28,
2001, magnitude 6.8 earthquake experienced by the Puget Sound region. The pre-existing scarp
appeared to have lengthened to the south by approximately 10 feet and has increased to
approximately 48 inches. The scarp, previously located west of and outside the footprint of the
existing rockery on the Lehn property; has extended approximately 7 feet.uphi11 and to the east,
and is now within the rockery footprint. Displacement of the rockery has occurred west of the
new scarp location.
The earth movement activity, as evidenced by the February 1998 landside, the pre-existing scarp
observed during our February 2001 reconnaissance, and apparent reactivation. of the pre-existing
scarp during the February 28, 2001 earthquake represents an extremely high risk of imminent
landsliding in this area. Based on the topographic and inferred geologic conditions at the site,
the same topographical, geological and hydrogeological factors, which precipitated the 1998
landslide, are likely present in the area of the currently observed movement. Therefore, the risk
of landslide activity affecting the existing homes located at the toe of the slope is also considered
to be extremely high; Future significant earth movement will have additional adverse impact to
your property. Since a significant increase in rainfall could reinitiate the earth movement at any
time, we recommend this area be closely monitored for signs of recurring movement. We further
recommend that the downslope, residents be notified immediately of the high risk of landslide
activity on the slope. Further study and mitigation for the area to reduce the risk of future
landslide activity should be performed immediately. We recommend that this .information be
shared with the downslope -residents.
It is- our understanding that the geotechnical consultant (Adapt Engineering), representing one of
the downslope residents performed a post -earthquake reconnaissance of the site on March . 12,
2001. Information gathered during this field visit and any other previous field visits made by
Adapt Engineering, or -any other consultant, should be evaluated immediately to help determine
the appropriate course of action to reduce the landslide hazard to your property and the
downslope residents.

RE: FOLLOW-UP SITE VISIT
WALKER LANDSLIDE
162ND BLOCK OF 75TH PLACE WEST
EDMONDS, WASHINGTON
Dear Ms. Graf:
April 16, 1998
APR 1 # 6
This letter documents additional observations and opinions related to the above -referenced landslide.
At the City of Edmonds's (City) request, a follow-up visit was made to the site on April 3, 1998 to observe
existing conditions related to the landslide that occurred at the site on February 13, 1998. The information
provided in this letter supplements observations and recommendations provided in our letter dated February
19, 1998.
The physical extent of the slide area has changed very little from that observed on February 13. Since
February 13, water flow within the slide area has reduced to a minor trickle, and the slide debris at the toe of
the slope (back yard of the Walker residence) has consolidated and settled (likely due to collapse of voids and
drainage of water within the slide debris). A new, corrugated I3DPE pipe (apparently for collecting and
diverting groundwater seepage) extends from the upper portion of the slide area to the City's catch basin
located above the neighbor's garage to the south. Vegetation is gradually being reestablished in the landslide
scar.
Based on our latest observations, conditions within the slide area appear to have improved since
February 13. The existing slide debris at the toe of the slope has stabilized, and drainage control (the new
pipe) has apparently reduced the impact of groundwater seepage on the slide area. Accordingly, it is our
opinion that the existing conditions resulting directly from the recent slide are not a threat to the residence.
In providing this opinion, we assume that the drainage measures installed after the slide will be maintained.
This opinion is not intended to apply to broader slope stability issues at the site, or to the generally understood
risk of instability at sites located within the Meadowdale area. Although the recent landslide has heightened
awareness of the possibility of such events, it is unlikely that the current overall risk of landsliding at the site,
and in the vicinity, is substantially different than the potential risk that existed before the landslide.

Dear Mrs. Walker,
This is a follow-up to City letter dated 2/20/98 which informed you of a slope failure on a portion of
property you own in the Meadowdale area of Edmonds. The letter required that you enlist the services of
a professional engineer to evaluate the slope and provide a report. It is our understanding that your
engineer, Mr. Bill Laprade, met with City officials on your behalf on 3/12/98. He was provided with
Meadowdale slide area studies, maps and LID information in an attempt to provide the necessary report.
However, as of this date we have not received the required report or even a site reconnaissance letter that
addresses temporary measures to mitigate further slope failure.
The adjacent property owner to the east has complied with the City and provided a report (Earth
Consultants, copy enclosed). The recommendations include additional site investigation and short term
and long term mitigation work. Please note the engineer states, "The site conditions do not warrant
vacating the residences at the top and bottom of the slope." Even though this is a favorable response
regarding your residence and the adjacent site conditions,. the City shall still require that your engineer
make a similar recommendation as to the safety of your home and adjacent properties in his report.
It is essential that you respond to the City and submit a report which provides a plan for temporary and
permanent slope protection and slope mitigation, as well as temporary and permanent erosion control and
surface or subsurface drainage improvements. As noted before, work deemed "emergency" by the
geotechnical engineer shall be immediately installed (provided no City permits or discretionary approvals
are necessary). Temporary or permanent work that requires a permit must be reviewed and approved by
the City, prior to the start of work, for review under Ordinance #2661 which regulates the Meadowdale
Earth Subsidence Landslide Hazard Area.

Dear Ms. Walker,
As you know, City officials conducted a site inspection on February 13, 1998 and observed a
slope failure on a portion of property you own at 16209 75th Place West in Edmonds.
Accompanying City officials were representatives of Landau Associates, professional
geotechnical consultants for the City. Landau Associates conducted a site. reconnaissance and
subsequently prepared a report, copy enclosed.
Based on the findings in the report and pursuant to Uniform Building Code Section 3307,
Excavation and Grading, the City shall require that you enlist the services of a State licensed
Geotechnical Engineer to monitor the site and conduct a detailed site investigation of the slope
failure. By March 6, 1998 the engineer must provide a report and plan for temporary and
permanent slope protection and slope mitigation, as well as temporary and permanent erosion
control and surface or subsurface drainage improvements. Any work deemed "emergency" by
the geotechnical engineer shall be immediately installed (provided no City permits or
discretionary approvals are necessary). Temporary or permanent work that requires a permit
must be reviewed and approved by the City, prior to the start of work, for review under
Ordinance #2661 which regulates the Meadowdale Earth Subsidence Landslide Hazard Area.
Please note, Landau Associates recommends that your home be to orariy vacated until site
drainage systems are repaired and water flow within the slide area has been diverted or otherwise
controlled. You should review this matter with your geotechnical engineer for concurrence with
this recommendation since the City consultant review was preliminary without detailed
investigation.

RE: SITE VISIT
LANDSLIDE IN 162ND BLOCK OF 75TH PLACE WEST
EDMONDS, WASHINGTON
This letter documents observations and recommendations related to a recent landslide in the 162nd
block of 75th Place West. At the City of Edmonds's (City) request, a representative of Landau Associates
visited the slide location to observe site conditions. Our representative met Don Fiene and Mike Lynn of the
City at the site.
The slide apparently occurred some time on February 13. At the time of our visit, the slide extended
from the top of the bluff to a point about 40 ft east of the house and ranged from about 30 to 40 ft in width.
The slope above the house consists of a moderately steep lower portion extending up to a relatively broad
midslope bench. The slope portion above the bench consists of a very steep to nearly vertical bluff. The slide
appeared to have originated near the top of the bluff. Slide debris crossed the top of the midslope bench and
scoured vegetation and near surface soil from the face of the lower slope. Post -slide conditions within the slide
area consisted of loose to soft, moist to saturated soil on the bench, lower slope, and across an approximately
20 ft wide lawn area west of the toe of the slope. Rivulets of water were observed flowing down slope within
the slide area. A mangled exposed portion of a drainage system was also observed near the top of the lower
slope within the slide area.
Conditions exposed near the top of the bluff (both within and adjacent to the slide area) consisted of
layered silt and sand units which appear to correspond to very dense and hard glacial outwash deposits
typically found in the site vicinity. Some minor seepage was observed from the base of sand units exposed
in the slide area, and surface moisture from seepage was observed on the face of silt units exposed to the south
of the slide area Significant quantities of flowing water were observed at two locations north of the slide area.
One source was observed at a point about 25 to 30 ft below the top of the bluff and just a few feet north of the
slide area. Water observed at that location (south) was estimated to be flowing at a rate of several gallons per
minute and was determined to be the source of the water observed flowing down the slide area. The point of
expression of the south water source could not be observed at the time of my visit. Another water source

(north) with a similar flow rate was observed about 30 ft north of the slide area. Water from the north source
was being channeled downslope away from the slide area through what appeared to -be fairly -well established
drainage paths. Based on the direction of the flow (and flows observed on the property to the north in a storm
drainage system at the base of the slope), the north source apparently was previously identified and has been
managed for some time. It is possible that the south source of water was being picked up by the existing
drainage system observed within the slide area, but conditions within the slide area obscured observation of
a direct connection.
Soil within the slide area is predominantly sandy and moist, except where exposed to flowing water.
Movement within the slide area was not observed at the time of our visit. A gradual ponding of water was
observed within the lawn area at the base of the slope. Prior to our leaving the. site, several city employees
arrived and began repairing the damaged drainage system and channeling water flow away from the house.
The loose and soft soil within the slide area may become saturated during wet weather or due to water
flow from above. If so, mud flows are likely to occur within the slide area. To limit the potential for mud
flows, additional sliding, or erosion to occur; water flow to or within'the slide area should be controlled or
eliminated, and vegetation reestablished as soon as possible. Ideally, water flows directly impacting the slide
area should be picked up prior to where they enter the slide area. At a minimum, flow within the slide area
should be diverted to the existing drainage, system if that system is still functioning. As an interim measure
(prior to revegetation), covering the slide area within the bench and lower slope with plastic sheeting would
help limit potential soil saturation from precipitation and related soil movement.
Based on the nature of the slide, the moderate steepness of the lower slope, and the presence of
substantial run out space between the base, of the slope and the house, it appears unlikely that the house is in
immediate danger from additional sliding of a similar nature. However, it,may be prudent to have the residents
of the house temporarily move out until site drainage systems are repaired and water flow within the slide area
has been diverted or otherwise controlled.
We appreciate this opportunity to be of assistance to the City. If you have any questions regarding the
content of this letter, or need additional assistance, please call.

immediate danger from additional sliding of a similar nature. However, it may be prudent to have the residents
of the house temporarily move out until site drainage systems are repaired and water flow within the slide area
has been diverted or otherwise controlled.
We appreciate this opportunity to be of assistance to the City. If you have any questions regarding the
content of this letter, or need additional assistance, please call.

Dear Ms. Walker:
SUBJECT: EXTRA SIDE SEWER CONNECTIONS
During. -the construction of the North Meadowdale
project, you were notified that each "extra" side sewer
connection would cost $900.in retrospect, we felt that
each existing habitable house .should receive a side sewer
connection without the additional fee.
The attached memo from the Community Services Director
is notification that the City will not attempt to collect
the additional charge from you in the future.
Thank you for your cooperation in this matter.
Very truly yours,
JEZ�/, Awl l

Subject: Meadowdale Sidesewer Connections
I have reviewed your September 9, 1985, memorandum, as well as the
letter that went out last year notifying property owners of the City's
policy on charging for additional side sewer connections. I.agree with
your recommendation that, if we had had more time to make the decision,.
we would have allowed all existing houses to connect without additional
charge. The "extra" connections would have applied, therefore,_only to
additional lots which would be developed at a future time. The .
rationale for the distinction is that the existing houses had been, and
still are, paying the bi-monthly sewer charges.
I request that you take whatever measures are necessary to see that the
two cases which are affected by this policy clarification -- Nelson and
Walker -- are propertly notified and either reimbursed or "forgiven"
for the extra charge that may have been made or billed to them. I
assume Finance will have to be notified.
