Re: E98-0002
City of Tukwila Public Works Project
1996-1997 Winter Storms Event FEMA
South 104th Riverbank Sloughout/Drainage
City Project No. 97-DRO2
Project Description:
This SEPA review is for the stabilization of approximately 80 linear feet of riverbank on
the Duwamish River. This work includes the removal and restoration of 8 x 100 linear
feet of existing pavement, excavation and restoration of approximately 75 linear feet of
access road, construction of a rock toe key and vegetated geogrid, installation of fish
habitat components, revegetation of the disturbed areas, and installation of a catch
basin and pipe under South 104th Street (outfalling to the Duwamish River).
Agencies with Jurisdiction:
None.
Summary of Primary Impacts:
• Earth
The riverbank at this location is steep, containing Class 2 slopes which are
nearly vertical where sloughouts have occurred. The foundation soil includes
sands with gravels at the upper soils levels and silty sands and silts at the lower
pile elevations which are typical of those found along the Duwamish River. In
the past, the riverbank and roadway foundations in the vicinity have required
remedial work for stabilization purposes.
There will be approximately 1,200 cubic yards of excavation and fill to
accommodate the construction of the 75 foot long access road. This road will
drop 12 linear feet from the existing roadway grade. An erosion control plan will
be employed during construction.

• •
• Air
Dust and exhaust emissions will be generated during construction, with watering
as necessary to control dust.
• Water
Portions of the proposed construction must occur within the O.H.W.M of the
Duwamish River. Although erosion control measures will be in place, some silt
will likely enter the Duwamish as a result of construction activities. Construction
will occur at low tides and will be carried out expeditiously. A catch basin and
outfall pipe will collect and convey drainage from the street and adjacent
properties to a discharge point in the rip rap. This mitigation will prevent future
saturation of the upper bank as required by FEMA.
• Plants
Blackberry and various grasses are currently found along the riverbank.
Proposed property restoration suggests a constructed geogrid with willow
plantings of Red Osier Dogwood (Cornus stolonifera) along the upper and lower
riverbank. However, due to the salinity of the river at this location, Red Osier
Dogwood will not tolerate inundation. Staff recommends the substitution of
Pacific Willow (Salix lasiandra) and Sitka Willow (Salix sitchensis) for use along
the lower riverbank. Both Willow species have salinity tolerance. Red Osier
Dogwood may be used along the upper riverbank. Plantings are to occur above
the O.H.W.M. to provide additional riverbank stabilization and will replace the
existing blackberry and grasses in that location. Additionally, seeding and the
embedding of tree trunks will occur in the rip rap.
• Animals
Northwest Chinook Salmon are found in the Duwamish River and may be listed
as a threatened species in 1999. The river is part of a migration route for
anadromous fish. The site is located within the Pacific Flyway, a migration path
for various waterfowl.

FROM: Gary Schulz, Urban Environmentalist
DATE: March 5, 1998
RE: River Bank Stabilization/Repair on S. 104th Street - SEPA E98-0002.
At your request, I have reviewed the SEPA checklist, plan drawings, and contract document for this
project. Also, I have visited the site with planning and public works staff. The project is obviously
an emergency situation. My comments are as follows.
SEPA checklist
1) Under Section 4. Plants, "red osher polewood" is meant to be red osier dogwood. Due to the
salinity of the River in this location, I would not use this shrub on the bank where it may be
inundated. I would recommend that both Pacific willow (Salix lasiandra) and Sitka willow (Salix
sitchensis) cuttings be used in this project as they have some salinity tolerance.
2) Under Section 5. Animals b., it would be reasonable to mention the proposed listing of
Northwest Chinook salmon. Under c. I think the site is part of a migration route for anadromous fish
and we are located within the Pacific Flyway which is migration of waterfowl etc.
Riverbank Plans
1) My first comment is repeated from above which is not to stake red osier dogwood low on the
bank; however, it is appropriate to stake it on the upper portion. Secondly, the temporary access
road, as shown, may require some stabilization after it is excavated into the river slope. Due to the
oversteepened condition of the bank some additional toe rock could be necessary.

104th St. River Bank Stabilization
3/5/98
Page 2
Contract Document
1) Even though there is a 1 -year 10% retainage for the purpose of guaranteeing the work, the
specification of 75% survival of plantings after 1 year could be expanded to include cover and vigor
of willows. I observed the last bank fix to the east to have relatively poor willow growth and cover.
I would recommend that there be some additional language to encourage better growth and
additional staking of cuttings for areas that do not exhibit good growth the first year.
Please let me know if you have any questions.

Waiver of Development Permit (L98-0005)
PMT's
When you originally submitted this application I advised you that one set of. PMT's
reduced to 8-1/2" x 11" was required. This is necessary so that copies of the plans can
be sent to the appropriate agencies as part of the notice process.
When we discussed this requirement, you indicated that Public Works did not have the
capability to accomplish this. Michael Jenkins advised me that Kinko's will reduce the
plans to either 8-1/2" x 11" or 11" x 17".
As this is a standard requirement which Public Works has always met in the past,
please make arrangements to have a complete set of the plans reduced and
returned to me by no later than Friday, March 6th. Any delay beyond this date will
impact the notification process and delay the processing of SEPA and the Development
Waiver.

DEVELOPMENT
In response to your request for added input on right-of-way and emergency actions related to this project, I
provide the following:
S. 104th Street Right -of -Way:
South 104th Street into which this riverbank sloughout has occurred (see attached map) is currently used
as a commercial street in a public right-of-way. From my discussion with the City's engineering
consultant, Mike Yoeman, L.L.S. who has researched the S. 104th right-of-way, being in a public right-of-
way means the City has prescriptive rights, which means:
- The City is the owner of the pavement where S. 104th currently exists
- Also, the City has all precriptive land rights to maintain the integrety of the
roadway, including ditches, and suporting riverbank to the toe of their respective slopes
(in this case, to the toe of the ditch on the east side of the road; and, to the toe of the
Duwamish River on the west side).
Mike Yoeman has researched the width of the right-of-way for S. 104th and finds the City currently has a
60 foot right-of-way, eventhough some maps indicate only a 40 foot width.
There is a very narrow section of privately held land (approximately 60 square feet on one parcel and
approximately 100 square feet on the other parcel) which may be within the construction zone under the
ownership of two properties. As with past riverbank projects within 300 feet of this project, the City (and
previously, King County when this area was in unincorporated King County) will secure two temporary
construction easements from the two property ownerships. Mike Yoeman advises this is appropriate.
Evenso, according to Mike Yoeman, P.L.L., because this is a repair project and the re-establishment of the
bank in a manner is to maintain the integrety of the roadway, all work to the ditch line or toe of riverbank
is within the prescriptive rights of the City.
City Emergency Actions:
The slough in of the S. 104th Street riverbank and a portion of the shoulder, structural sub -base and asphalt
pavement occurred at the time of and as a result of the 96'/'97 Winter Storms Event. The City responded
to this federal declared disaster at the local level by:
1. A Local Procalmantion of Emergency by the Mayor of the City of Tukwila (December 30, 1996)
2. Resolution No. 1370 of the City Clouncil declaring an emergency in response to damages to public
and priaave property due to sever weather conditions.
I hope this information is helpful to your Department in making your decision on my request for waiver to
the Shoreline Substantial Development Permit (L98-0005).
If you have any questions please do not hesitate to call me at Extension #1641.
