♦ A _ ♦ Environmental Checklist
Background
Honey Creek, a 1.2-mile tributary to May Creek, has experienced serious
in-stream salmonid habitat and water quality degradation due to high-
density residential stormwater inputs and roadway related bank and
ravine destabilization.
Previous stream survey and inspection work conducted by RH2
Engineering and King County indicates that most of Honey Creek is
utilized by cutthroat trout. Coho salmon have been stocked at times, but
no evidence of their survival or return to the stream exists to date. Adult
and juvenile coho and chinook salmon do utilize May Creek, to which
Honey Creek is tributary.
In the project reach near Devil's Elbow, Honey Creek flows through two
culverts and a concrete ring structure. The City of Renton, the Muckleshoot
Indian Tribe (MIT), the Washington Department of Fish and Wildlife
(WDFW), and King County (KC) met previously to identify restoration
strategies for this section of Honey Creek. WDFW and the Tribe expressed
a preference that the City removes the 54-inch diameter culvert because it
is believed to be a fish passage barrier.
Project Objectives
1. Daylight this portion of Honey Creek by removing the 54-inch culvert.
2. Improve the fisheries habitat characteristics of the site via bank
restoration/stabilization, planting, and in-stream habitat features.
3. Reduce sediment accumulations in the 60" culvert via channel creating
a small sediment trapping and removal area upstream of the culvert.
4. Obtain long term (10-year) HPA permit conditions, which will allow the
City to maintain the sediment trap.
Project Approach
The project involves: removal of the existing 54-inch diameter, 98 foot
long culvert from Honey Creek; removal of the concrete ring structure;
removal of concrete walls from the stream corridor; creation of a small
sediment trapping area; re-grading approximately 160 feet of the stream
banks; installation of Large Woody Debris (LWD) for habitat; removal of
invasive exotic vegetation from the stream banks; installation of dense
native plantings on and above the banks for salmonid cover and shade;
installation of spawning size gravel; and bank stabilization with rock,

geo-textile and native vegetation. Bank and channel rock was used to: 1)
withstand the high velocities experienced in this ravine stream impacted
by urban stormwater inputs, 2) prevent bank failure from the existing
unstable steep banks which experience frequent mass wasting, and 3)
accommodate improved channel width and depth in this reach while
minimizing impacts to the existing unstable banks on the east side of the
channel and while avoiding impacts to the existing road and sewer
facilities and the west side of the channel.
Live stakes will be joint-planted between the rock for additional bank

stability and habitat value. The wing walls on the upstream side of an
existing 60-inch culvert will be extended into the ground several feet below
the culvert to prevent scour from damaging the culvert.
The creek will be temporarily diverted around the construction site. Any
fish within the construction area will be relocated downstream of work site.
Construction of this project is expected in the summer of 1998.
B. Acreage of Site:
The project site involves approximately 160 linear feet of Honey Creek
with a work area of approximately 0.12 acres. The work conducted below
the historic ordinary high water mark to reconstruct the stream channel
and banks affects approximately 0.03 acres. Additional work affecting
areas above the ordinary high water mark involves approximately 0.09
acres. (Refer to B. Environmental Elements, 1.Earth, e.) .

The stream banks and bed are composed primarily of sand, silt and small
gravel. A test boring was drilled approximately 25 feet west of the stream
channel to a depth of 38.5 feet below existing grade. Generally, the boring
consisted of 11 feet of colluvium, which consists of very loose silty fine to
medium sand and very soft sandy silt with occasional.organic material.
Below this depth exists very dense clean to silty sands and hard sandy silt.
d. Are there surface indications or history of unstable soils in the
immediate vicinity? If so, describe.
Yes. There is evidence of frequent stream bank erosion and destabilization.
Landslides are common in this area.
e. Describe the purpose, type, and approximate quantities of any
filling or grading proposed. Indicate source of fill.
Excavation and grading activities will be necessary to remove the 54"
culvert, reconstruct the channel to approximately 10 feet wide, construct a
sediment trapping pool, grade the banks, remove the existing concrete
walls, remove piled rip-rap from the stream corridor, create a habitat pool,
and to install Large Woody Debris (LWD) for habitat.
The banks will be excavated to allow for a slope of approximately 13/4: 1 to
2:1. Grading will involve approximately 160 linear feet (about 2500 square
feet) of stream bank area. Total excavation at the site involves
approximately 825 cubic yards of earth materials from the historic stream
corridor, current streambed, and banks. The total area affected by
excavation is approximately 0.12 acres.
Of the total, an estimated 300 cubic yards of earth materials will be
excavated from below the historic ordinary high water from the historic
stream channel and its bank. In addition, approximately 20 cubic yards of
streambed material will be excavated from the current stream channel to
create a habitat pool in conjunction with LWD installation. The area
affected by this work is approximately 0.03 acres. This excavation would
occur on the creek banks and also in the creek.
Filling activities include: the placement of rock walls along the stream
banks for stability (67 cubic yards), installation of filter gravel (107 cubic

yards) and rip-rap (84 cubic yards) in the sediment trapping area, and
installation of spawning gravel (12 cubic yards). Total fill will involve
approximately 270 cubic yards of materials. Fill material would be
obtained from a local gravel pit in Kent or Auburn.
f. Could erosion occur as a result of clearing, construction, or use? If
so, generally describe.
Yes, erosion along the stream corridor could occur during construction, see
B.1.h. below.
g. About what percent of the site will be covered with impervious
surfaces after project construction (for example, asphalt or
buildings)?
None.
h. Proposed measures to reduce or control erosion, or other impacts
to the earth, if any:
Erosion in the project area will be minimized by erosion and sediment
control measures. The stream restoration may deliver some sediment to
the creek on a short-term basis. Temporary erosion and sediment control
measures will be implemented. The procedures include routing the
stream around the construction area, filter fencing, sand bagging,
hydroseeding, and mulching over exposed soils. After the banks are set
back, the new slopes will be vegetated with native species. Potential
erosion will be limited by doing the construction during the dry season.
Approximately one week prior to beginning construction activities on the
site, turbidity monitoring will be started approximately 100 feet
upstream of the construction site. This data will be used to establish
background turbidity concentrations in Honey Creek. During
construction and for one week after construction has ended, turbidity
monitoring will be employed approximately 100 feet upstream and 100
feet downstream of the construction site on Honey Creek. Data will be
evaluated on an on-going basis. Downstream turbidity levels exceeding 5
NTU's above upstream conditions will be considered indicative of
construction site impacts. Corrective actions will be implemented

immediately to eliminate the construction site source of turbidity to the
stream.
Contingency actions for stream impacts will be outlined and discussed in
the pre-construction meeting with contractors. Actions will include use of
Baker Tanks, employing other containment structures, disposing of
turbid water into the sanitary sewer, overland infiltration or spray
irrigation of turbid water, and placement of straw and silt fences.
Pumps, hoses, straw, one Baker Tank, and fencing materials shall be on-
site during the construction period.
2. Air
a. What types of emissions to the air would result from the proposal
(i.e., dust, automobile odors, industrial wood smoke) during
construction and when the project is completed? If any, generally
describe and give approximate quantities, if known.
During construction, there will be minor dust and internal combustion
engine emissions. Construction will be limited to daylight hours.
b. Are there any off-site sources of emissions or odor that may affect
your proposal? If so, generally describe.
None known.
c. Proposed measures to reduce or control emissions or other
impacts to air, if any:
Idling equipment will be shut off during construction.
3. Water
a. Surface:
1) Is there any surface water body on or in the immediate

type and provide names. If appropriate, state what stream
or river into which it flows.
Yes. Honey Creek is the focus of this restoration project. Honey
Creek is a 1.2-mile tributary to May Creek. May Creek flows into
Lake Washington. The culvert that will be removed is in a portion of
Honey Creek known as Devil's Elbow. About 1000 feet downstream
from this area is the confluence with May Creek. The project site is
approximately 1.6 miles from Lake Washington.
2) Will the project require any work over, in or adjacent to
(within 200 feet) the described waters? If yes, please
describe and attach available plans.
Yes. The restoration work will occur along about 160 feet of Honey
Creek and its banks. The purpose of the project is to return the
creek to a more natural state. The process will require the removal
of long culvert and fill associated with the culvert. The banks along
the stream channel will be re-graded and stabilized with rock and
vegetation.
3) Estimate the amount of fill and dredge material that would
be placed in or removed from surface water or wetlands and
indicate the area of the site that would be affected. Indicate
the source of fill material.
Of the total excavation (825 cubic yards), an estimated 300 cubic
yards of earth materials will be excavated from below the historic
ordinary high water (OHWM) from the historic stream channel and
its bank. In addition, approximately 20 cubic yards of streambed
material will be excavated from the current stream channel to create
a habitat pool in conjunction with LWD installation. The area
affected by this work (below the OHWM) is approximately 0.03
acres. This excavation would occur on the creek banks and also in
the creek.
Filling activities include: the placement of rock walls along the
stream banks for stability (67 cubic yards), installation of filter
gravel (107 cubic yards) and rip-rap (84 cubic yards) in the sediment

trapping area, and installation of spawning gravel (12 cubic yards).
Total fill will involve approximately 270 cubic yards of materials.
Fill material would be obtained from a local gravel pit in Kent or
Auburn.
4) Will the proposal require surface water withdrawals or
diversions? Give general description, purpose, and
approximate quantities, if known.
Work within the stream channel will require a temporary stream
by-pass. Sandbags will be used to dam the creek. The creek could
then be diverted through the construction site a couple of ways,
depending on creek conditions. A temporary pipe could be imbedded
in the sandbags and used to convey water through the construction
site. The second and most likely method would be to pump the
water around the construction site through a pipe. The stream
water will be conveyed through the pipe directly to the stream
channel, just downstream of the construction site. The water will
not be dispersed on the site.
5) Does the proposal lie within a 100-year floodplain? If so,
note location on the site plan.

No.
6) Does the proposal involve any discharges of waste materials
to surface waters? If so, describe the type of waste and
anticipated volume of discharge.
No.
b. Ground
1) Will ground water be withdrawn, or will water be
discharged to ground water? Give general description,
purpose, and approximate quantities, if known.

2) Describe waste material that will be discharged into the
ground from septic tanks or other sources, if any (for
example: domestic sewage; industrial, containing the
following chemicals ....; agricultural; etc.). Describe the
general size of the system, the number of such systems, the
number of houses to be served (if applicable), or the number
of animals or humans the system(s) are expected to serve.
None.
c. Water Runoff(including storm water):
1) Describe the source of runoff (including storm water) and
method of collection and disposal, if any (including
quantities, if known). Where will this water flow? Will this
water flow into other waters? If so, describe.
Stormwater discharge from nearby development drains directly into
Honey Creek and will continue to do so after project completion.
Stormwater runoff during construction is expected to be minimal
since work will be conducted in the summer. However, any runoff
that does occur will be passed through filter fabric fencing before
being discharged into the creek. The existing storm drain and catch
basin that drains runoff from NE 27th Street drains into the concrete
ring in the Creek will be removed. A new storm drain and catch
basin will be constructed 20 feet south of the existing drain and will
route runoff from NE 27th Street to an energy dissipater near the
stream (refer to plans).
Erosion in the project area will be minimized by erosion and
sediment control measures. The stream restoration may deliver
some sediment to the creek on a short-term basis. Temporary
erosion and sediment control measures will be implemented. The
procedures include routing the stream around the construction
area, filter fencing, sand bagging, hydroseeding, and mulching over
exposed soils. After the banks are set back, the new slopes will be
vegetated with native species. Potential erosion will be limited by
doing the construction during the dry season.

2) Could waste materials enter ground or surface waters? If so,
generally describe.
As noted above, some sediment could enter Honey Creek during
construction. There is also the possibility that construction vehicles
could leak small amounts of petroleum products onto the ground
during routine operations. Construction equipment will be inspected
daily for leaks.
d. Proposed measures to reduce or control surface ground, and
runoff water impacts, if any.
A temporary erosion and sediment control plan and best management
practices will reduce the erosion and filter the sediment during
construction. This plan will utilize filter fences, hydroseeding, straw
mulching over exposed areas, and flagging of sensitive areas. In addition,

the project activity will occur during the dry season. Excavated areas and
side slopes will be stabilized with vegetation. The vegetation should
provide long-term benefits to the stream in terms of erosion control and
habitat protection. Construction best management practices (BMP's) will
be used to minimize the potential for accidental spills of fuel or oil from
heavy equipment during construction.
Approximately one week prior to beginning construction activities on the

RIPARIAN RESTORATION PLAN FOR
THE DEVIL'S ELBOW LIFT STATION REPLACEMENT
(PHASE 2: HONEY CREEK RSTORATION PROJECT)
1.0 PROJECT SUMMARY
The City of Renton removing a 54-inch diameter 98-foot long culvert from
Honey Creek and restoring and stabilizing the banks. The creek restoration in-
cludes approximately 170 linear feet of Honey Creek in Renton, Washington
(shown on Figures 1 and 2). This report describes the elements of the restoration
plan for the riparian stream banks.
The Devil's Elbow site is located west of the unimproved intersection of NE 27th
Street and 120th Place SE in the City of Renton. The site is relatively flat,but
slopes steeply along the banks of the creek and to the east and west. The vegeta
tion of the Devil's Elbow site consists of several deciduous tree species with an
understory of scrub-shrub and herbaceous plants, including several exotic spe-
cies.
1.1 Regulatory Background and Permits
Honey Creek is not regulated under the City of Renton Shoreline Master Pro-
gram; environmental impacts are regulated through the City of Renton
Environmrntal Ordinance (SEPA). Clearing within 25 feet of the edge of the
stream or 15 feet from the top of bank is regulated under the City of Renton Land
Clearing and Tree Cutting Ordinance (Ordinance No. 4219, City of Renton Mu-
nicipal Code).
Washington State, through the Department of Ecology (DOE), has authority to
issue Temporary Water Quality Exceedance Approval. Hydraulic Project Ap-
proval (HPA) permits for work within a stream channel arc issued through the
Washington State Department of Fish and Wildlife (WDFW).
The Muckleshoot Indian Tribe, King County DNR, WDFW, and the City of Ren-
ton have worked cooperatively to identify strategies to improve Honey Creek.
Under Section 404 of the Clean Water Act, the US Army Corps of Engineers
(Corps) and the US Environmental Protection Agency (USEPA) have joint
authority over waters of the United States, including streams and wetlands.
These agencies regulate the discharge of dredged and fill materials into waters of
the United States through the Corps permitting process.

1.2 Impacts
The City of Renton proposes to divert Honey Creek to remove the 54-inch culvert
and concrete walls and install a sediment trap,LWD (logs and root wads),bank
vegetation, and riprap (photos 1 and 2). Temporary impacts may include small
quantities of sediment entering the creek during clearing and grading, and
clearing of vegetation. No permanent impacts associated with development of
the site are expected.

2.2 Description of the Overall Project
The Devil's Elbow project consists of two phases,which are proposed to occur
almost simultaneously. Phase 1 involves removal and replacement of the lift
station. Phase 2 is designed to improve fish passage and habitat with the fol-
lowing:
• removing the 54-inch culvert
• daylighting the channel
• removing the concrete walls along the culvert
• installing riprap and vegetation for bank stabilization
• installing large woody debris for habitat
• joint planting in the riprap for fish cover
• removing invasive plants
• planting native plants for habitat
3.0 ECOLOGICAL ASSESSMENT OF CREEK TO BE IMPACTED
The project includes approximately 170 linear feet of the Devil's Elbow reach of
Honey Creek. Maps of the project site and the restoration plan are included in
Cooke Scientific Services.Inc 2 Ante 17.1991s
this report. A summary of the creek and bank areas and the proposed impact is
given below.
3.1 Existing Water Regime
Honey Creek is a 1.2-mile long tributary of May Creek, which drains into Lake
Washington approximately 1 mile northwest of the site. In the Devil's Elbow
Reach,Honey Creek flows to the northwest through a narrow, steep-walled val-
ley.
On the Devil's Elbow site,water flows approximately 100 feet through the 54-
inch culvert and empties into a concrete ring structure south of the NE 27th
Street culvert (see photo 3). Two additional culverts, 12-inch and 18-inch, empty
into the concrete ring structure from stormwater to the south and north, respec-
tively. Water then flows from the concrete ring structure at the downstream end
of the 54-inch culvert (photo 6) under NE 27th Street through a 60-inch culvert
(photo 1). Considerable instream debris produce several elevation drops from 2
to 2-1/2 feet, creating fish barriers upstream of the culverts. Sedimentation in the
culverts may prevent fish passage in some areas. The steep-sloped walls along
Honey Creek fail frequently contributing to sediment loading in the creek. In-
tense development surrounding the creek has increased peak stormwater flows
and frequencies, increasing erosion and incision into the creek.
3.2 Existing Vegetation
Vegetation growing upstream of NE 27th Street includes bigleaf maple (Acer
macrophyllum), red alder (Alnus rubra), Sitka willow (Salix sitchensis), Pacific wil-
low (Salix lucida var. lasiandra), Himalayan blackberry (Rubus procerus),
salmonberry (Rubus spectabilis), and reed canarygrass (Phalaris arundinacea).
Vegetation downstream of NE 27th Street consists of Himalayan blackberry,
Japanese knotweed (Polygonum cuspidatum), redstem dogwood (Corpus sericea
ssp. sericea), reed canarygrass, piggyback plant(Tolmeia menziesii), deer fern
(Blechnum spicant), and mosses. Fxotic plant species include Himalayan black-
berry,Japanese knotweed, and reed canarygrass. No endangered, threatened, or
sensitive species have been found or identified on the project site (Washington
National Heritage Program, 1991).
3.3 Existing Fauna
Previous stream survey and inspection work conducted by RH2 and King
County indicate that Honey Creek is utlli7ed both up and downstream of the
culverts by cutthroat trout. Coho salmon have been stocked in the stream at
times,but no evidence of their survival exists to date. Adult salmon utilise May
Creek, to which Honey Creek is a tributary. The fish that now live in the Devil's
Conies Scientific Services.Inc 3 Ante I?.199M
cedar, redstem dogwood and rose. The existing vegetation is Japanese knotweed
to the west(photo 8) and blackberry to the east(photo 9).
The first step in restoring the native vegetation will be removing existing exotic
and invasive vegetation;herbicide will be applied to invasive species whenever
possible. The banks will then be heavily planted so that returning invasive and
exotic species will be crowded and shaded out. Native species were selected on
the basis of their presence at other less disturbed locations along the creek, as
well as their erosion prevention characteristics.
4.2 Goals and Objectives for Riparian Restoration
• Improve the fisheries habitat characteristics of the site via bank
restoration and stabilization,planting, and/or in-stream habitat
features.
• Re-establish a predominace of native plants in the project area.
4.3 Proposed Performance Standards and Monitoring
Performance standards, or success criteria, are proposed for the Devil's Elbow
site to achieve the riparian restoration goals and objectives. Performance stan-
dards, listed below, will have to be accepted by regulatory agencies before they
can be finalized.
• Development of layers of scrub-shrub and forested communities
with sufficient density (percent cover) and canopy development to
provide bank stabilization and shading of fish runs.
• Establishment of minimum of 80 percent plant cover by native
plants with not more than 15 percent of the cover consisting of ex-
otic and/or invasive species in the restoration areas. Exotic and
invasive species may include,but are not restricted to,the follow-
ing: reed canarygrass, non-native blackberry, and Japanese
knotweed.
The performance standards will aid in determining the success of the restoration
project and will ensure that the restoration goals have been achieved. Monitor-
ing is an important part of the restoration sequence and ensures that the
performance standards are met. Regulatory agencies determine the timing of
monitoring. Monitoring should consist of the tasks listed below:
• Monitor vegetation characteristics (community type, species pres-
ence and percent cover) of the restoration areas to determine if
habitat type and density goals are met. Recommended methods for
long-term monitoring of vegetation status include establishing
permanent transect lines, sample plots, and photo stations.
Conks Scientific services.Inc 5 anvil 17.199
4.4 Hydrology
The planting design is based on the estimated hydrologic characteristics that
will be achieved after excavation and bank reconstruction. The stream varies in
depth and velocity across thc year with as much as 60 CFS in thc winter and 1
CFS by late August. Plantings have been selected based on their tolerance of
depth, frequency, and duration of inundation. Most plants have specific re-
quirements for these hydrologic characteristics (Cooke and Azous 1997,Taylor
1993).
4.5 Soils and Grading
Earthwork will be necessary during construction and renovation of the restora-
tion area. The removal of the 54-inch culvert and the concrete walls will require
bank regrading. A 6- to 12-inch deep filter layer of drainage gravel under 18
inches of riprap will be installed to filter sediment, withstand high velocity
stormwater, and withstand maintenance dredging of sediment. A riprap-lined
sediment collectin area will be created to the south of the road. The final con-
struction plan will be designed to create stable banks promoting fish habitat and
passage. Care will be taken during excavation to minimally disturb the steep
creek slopes as well as the emergency sewage storage pipe that lies parallel to the
creek.
Soil will be added to the upland (old lift station) after removal of the building
and underground vault. A layer of top soil 12 to 18 inches thick will be applied
to the lift area and where the existing gravel road will be restored to Creek bank
vegetation. The lift station hole will be filled in and soil placed in and over the
entire area. Then the lift area will be graded level.
4.6 Plants
Scrub-shrub and forested habitats were selected for the restoration design to re-
place and enhance lost communities. See attached plan sheet. Reference plant
communities were examined using less disturbed Creek reaches in order to de-
velop the plant list. The layout of the plant communities in both the Creek bank
and old lift station areas was designed to maximize interspersion of species, pro-
vide bank stability and shading for fish runs while considering the hydrologic
requirements of the plants. Exotic invasive plant species will be removed prior
to planting. Species to be used in the plantings are listed in Table 1.
Sitka willow and redstem dogwood stakes will be joint planted between the
riprap to provide cover and increased bank stability. The area upslope from the
riprap to the top of the bank will be a shrub community consisting of beaked ha-
zelnut, thimbleberry, and salmonberry. The steep 13/4:1 slope requires the
shrubs to be planted as stakes rather than pocket plantings. The upland on the
north side of the creek will be planted in beaked hazelnut to create shading. The
site of the old lift station south of the creek will be planted in large trees includ-
cake scientific Services Inc 6 A rfl 17.199N
planted within the riprap will be obtained at a length sufficient to penetrate up to
30 inches of riprap and filter to root in native soil. See Planting Schedule.
The planting sequence for the restoration will be to plant the trees and shrubs
first and then the herbaceous plants. It is expected that the planting will occur in
the fall of 1998. The single exception involves the availability of certain species.
Shrub species are supplied as bare root material during dormancy and in con-
tainers during the active growing season. Deciduous trees are supplied as bare
root during dormancy or in containers during the growing season. Evergreen
trees are generally supplied year-round as balled and burlapped or containerized
specimens.
4.7 Construction Management
The project biologist should be present on site during the various implementa-
tion phases of the creek restoration plan. It is always necessary to make field
adjustments to a planting plan as well as to supervise the planting of nursery
stock. In addition, it is important that the biologist examine and approve the
plant material before it is installed.
4.8 Watering
Plant material must have adequate water after installation. This is often the most
crucial component in ensuring the success of any wetland mitigation project.
There are several components of the design that can assist in the establishment of
plantings, especially during the critical phases. By planting during the fall or
early spring when the plants are in their hibernation phase, the plants' initial
need for water is decreased. Planting during this time period, typically the rainy
season, provides a natural source of water. Artificial watering will be necessary
during any spring installation and throughout at least the first growing season.
Hydrologic monitoring of this area will allow for an accurate determination of
the water needs of the plantings. Unlike the creek bank plantings, upland areas
are more likely to require additional water. Successful establishment of the up-
land plantings can be encouraged by planting as early as possible in the dormant
season in order to take advantage of the winter rains.
4.9 Landscape Maintenance
The objective of this restoration project is to stabilize the banks and improve fish-
eries habitat characteristics and fish passage through the Devil's Elbow reach of
Honey Creek. The only maintenance that would be required once the riprap is
installed and the creek banks and old-lift station site have been planted is re-
moval of weedy species. Exotic and invasive species, such as Japanese
knotweed, non-native blackberry, and reed canarygrass should be hand weeded
from the newly planted areas for two years after the installation. This will be
Cooke Scientific Services_Inc 8 Awn 17.199X
monitored accordingly. Preparation of a detailed monitoring plan in the final
restoration report will address any landscape maintenance necessary for the suc-
cessful completion of the restoration plan.
Mowing should be done only in the hydroseeded areas within the restoration
site. Any trees or shrubs that die over time should be left in place to provide ad-
ditional wildlife habitat,unless they are aesthetically objectionable or pose a
safety threat.
4.10 Site Protection
The creek will need to be sandbagged to divert the flow around the construction
site during the stream restoration phase. A pipe through the construction site
will divert stream flow, or the creek will be pumped to the downstream side to
the 60-inch culvert, depending on creek conditions. Any fish remaining in up-
stream pools will be removed and relocated downstream of the culvert. The 54-
_ inch culvert and the concrete wall can then be removed and riprap installed
without risk of sediment, erosion, or machinery affecting fish populations.
Orange barricade fencing will also be placed along the edges of the site to protect
the restoration area from encroachment during construction. Signs can also be
placed on the perimeter of construction areas to indicate the presence of the res-
toration area.
Earth work operations will be scheduled during dry weather to avoid erosion.
Hydroseeding would be installed after final grading, or after installation of
scrub-shrub and forested communities is completed. Hydroseed mixes will be
determined during the final design stage and will be compatible with native Pa-
cific Northwest plant communities. Hydroseeding would include wood mulch
and a tackifier to prevent erosion of soil and seed. If hydroseeding occurs too
late in the fall to ensure prompt seed germination, erosion blankets should be in-
stalled after the earthwork is done and planting is completed.
Any topsoil used in the buffer enhancement area should be applied during the
dry season as well. This will minimize erosion and subsequent sedimentation of
adjacent wetland areas.
4.11 Maintenance and Contingency Plans
This section will be completed for the final restoration report.
4.12 Implementation Schedule
Implementation of the Honey Creekreek restoration phase of the project is ex-
pected for the summer and early autumn of 1998. Construction times are based
on a fisheries window from approximately June 15 to September 15, 1998 when
culls Scientific Services.Ina 9 April 1?.199R
spawning runs will be minimally impacted. Phase 1 lift station removal is
scheduled for June through November 1998 overlapping the Creek restoration
phase.
Ideally, restoration should be done in either the fall or early spring when plants
are in hibernation and are most hardy for transplanting. Planting during this
time will take advantage of winter and spring rains and will maximize the op-
portunity for the successful establishment of plants. Early spring or fall planting
will also decrease the cost of plant materials because bare root plants may be
used. Planting later in the spring will require use of the more expensive balled
and burlapped or container-grown material as well as regular supplemental wa-
tering.
Earth work should be done during dry weather to minimize the risk of erosion
and sedimentation. This is especially important on this site as the banks along
the creek are very steep and susceptible to erosion and mass wasting. It may also
be difficult to impossible to move the soils during a wet period because the ma-
chinery may not be operable.

Project Narrative r r:C E C VE D
The above named project proposes to remove an existing 98 foot long, 54 inch diameter located in
Honey Creek. This culvert is located in Honey Creek approximately 13 feet south of the intersection
of the creek and NE 27th St.
Background
Honey Creek, a 1.2-mile tributary to May Creek, has experienced serious
in-stream salmonid habitat and water quality degradation due to high-
density residential stormwater inputs and roadway related bank and
ravine destabilization.
Previous stream survey and inspection work conducted by RH2
Engineering and King County indicates that most of Honey Creek is
utilized by cutthroat trout. Coho salmon have been stocked at times, but
no evidence of their survival or return to the stream exists to date. Adult
and juvenile coho and chinook salmon do utilize May Creek, to which
Honey Creek is tributary.
In the project reach near Devil's Elbow, Honey Creek flows through two
culverts and a concrete ring structure. The City of Renton, the Muckleshoot
Indian Tribe (MIT), the Washington Department of Fish and Wildlife
(WDFW), and King County (KC) met previously to identify restoration
strategies for this section of Honey Creek. WDFW and the Tribe expressed
a preference that the City removes the 54-inch diameter culvert because it
is believed to be a fish passage barrier.
Project Objectives
1. Daylight this portion of Honey Creek by removing the 54-inch culvert.
2. Improve the fisheries habitat characteristics of the site via bank
restoration/stabilization, planting, and in-stream habitat features.
3. Reduce sediment accumulations in the 60" culvert via channel creating
a small sediment trapping and removal area upstream of the culvert.
4. Obtain long term (10-year) HPA permit conditions, which will allow the
City to maintain the sediment trap.
Project Approach
The project involves: removal of the existing 54-inch diameter, 98 foot
long culvert from Honey Creek; removal of the concrete ring structure;
removal of concrete walls from the stream corridor; creation of a small
sediment trapping area; re-grading approximately 160 feet of the stream
banks; installation of Large Woody Debris (LWD) for habitat; removal of
invasive exotic vegetation from the stream banks; installation of dense
native plantings on and above the banks for salmonid cover and shade;
installation of spawning size gravel; and bank stabilization with rock,
Documentl\ 1-
geo-textile and native vegetation. Bank and channel rock was used to: 1)
withstand the high velocities experienced in this ravine stream impacted
by urban stormwater inputs, 2) prevent bank failure from the existing
unstable steep banks which experience frequent mass wasting, and 3)
accommodate improved channel width and depth in this reach while
minimizing impacts to the existing unstable banks on the east side of the
channel and while avoiding impacts to the existing road and sewer
facilities and the west side of the channel.
Live stakes will be joint-planted between the rock for additional bank
stability and habitat value. The wing walls on the upstream side of an
existing 60-inch culvert will be extended into the ground several feet below
the culvert to prevent scour from damaging the culvert.
The creek will be temporarily diverted around the construction site. Any
fish within the construction area will be relocated downstream of work site.
Construction of this project is expected in the summer of 1998.

be conducted concurrent with the stream restoration work. Phase 1 involves the
removal of the existing Devil's Elbow Lift Station and wet well approximately 10
feet west of Honey Creek. The current lift station will be replaced with a new
underground lift station located under NE 27th Street. The new lift station will be
approximately 120 feet northwest of the existing station. Phase 1 will also
include road improvements along NE 27th and installation of a force main. Some
limited slope stabilization along NE 27th Street in the Honey Creek stream
buffer will also occur in Phase 1. Erosion control measures and monitoring of the
creek will be implemented.

The stream banks and bed are composed primarily of sand, silt and small
gravel. A test boring was drilled approximately 25 feet west of the stream
channel to a depth of 38.5 feet below existing grade. Generally, the boring
consisted of 11 feet of colluvium, which consists of very loose silty fine to
medium sand and very soft sandy silt with occasional.organic material.
Below this depth exists very dense clean to silty sands and hard sandy silt.
d. Are there surface indications or history of unstable soils in the
immediate vicinity? If so, describe.
Yes. There is evidence of frequent stream bank erosion and destabilization.
Landslides are common in this area.
e. Describe the purpose, type, and approximate quantities of any
filling or grading proposed. Indicate source of fill.
Excavation and grading activities will be necessary to remove the 54"
culvert, reconstruct the channel to approximately 10 feet wide, construct a
sediment trapping pool, grade the banks, remove the existing concrete •
walls, remove piled rip-rap from the stream corridor, create a habitat pool,
and to install Large Woody Debris (LWD) for habitat.
The banks will be excavated to allow for a slope of approximately 13/4: 1 to
2:1. Grading will involve approximately 160 linear feet (about 2500 square
feet) of stream bank area. Total excavation at the site involves
approximately 825 cubic yards of earth materials from the historic stream
corridor, current streambed, and banks. The total area affected by
excavation is approximately 0.12 acres.
Of the total, an estimated 300 cubic yards of earth materials will be
excavated from below the historic ordinary high water from the historic
stream channel and its bank. In addition, approximately 20 cubic yards of
streambed material will be excavated from the current stream channel to
create a habitat pool in conjunction with LWD installation. The area
affected by this work is approximately 0.03 acres. This excavation would
occur on the creek banks and also in the creek.
Filling activities include: the placement of rock walls along the stream
banks for stability (67 cubic yards), installation of filter gravel (107 cubic

yards) and rip-rap (84 cubic yards) in the sediment trapping area, and
installation of spawning gravel (12 cubic yards). Total fill will involve
approximately 270 cubic yards of materials. Fill material would be
obtained from a local gravel pit in Kent or Auburn.
f. Could erosion occur as a result of clearing, construction, or use? If
so, generally describe.
Yes, erosion along the stream corridor could occur during construction, see
B.1.h. below.
g. About what percent of the site will be covered with impervious
surfaces after project construction (for example, asphalt or
buildings)?
None.
h. Proposed measures to reduce or control erosion, or other impacts
to the earth, if any:
Erosion in the project area will be minimized by erosion and sediment
control measures. The stream restoration may deliver some sediment to
the creek on a short-term basis. Temporary erosion and sediment control
measures will be implemented. The procedures include routing the
stream around the construction area, filter fencing, sand bagging,
hydroseeding, and mulching over exposed soils. After the banks are set
back, the new slopes will be vegetated with native species. Potential
erosion will be limited by doing the construction during the dry season.
Approximately one week prior to beginning construction activities on the
site, turbidity monitoring will be started approximately 100 feet
upstream of the construction site. This data will be used to establish
background turbidity concentrations in Honey Creek. During
construction and for one week after construction has ended, turbidity
monitoring will be employed approximately 100 feet upstream and 100
feet downstream of the construction site on Honey Creek. Data will be
evaluated on an on-going basis. Downstream turbidity levels exceeding 5
NTU's above upstream conditions will be considered indicative of
construction site impacts. Corrective actions will be implemented

immediately to eliminate the construction site source of turbidity to the
stream.
Contingency actions for stream impacts will be outlined and discussed in
the pre-construction meeting with contractors. Actions will include use of
Baker Tanks, employing other containment structures, disposing of
turbid water into the sanitary sewer, overland infiltration or spray
irrigation of turbid water, and placement of straw and silt fences.
Pumps, hoses, straw, one Baker Tank, and fencing materials shall be on-
site during the construction period.

type and provide names. If appropriate, state what stream
or river into which it flows.
Yes. Honey Creek is the focus of this restoration project. Honey
Creek is a 1.2-mile tributary to May Creek. May Creek flows into
Lake Washington. The culvert that will be removed is in a portion of
Honey Creek known as Devil's Elbow. About 1000 feet downstream
from this area is the confluence with May Creek. The project site is
approximately 1.6 miles from Lake Washington.
2) Will the project require any work over, in or adjacent to
(within 200 feet) the described waters? If yes, please
describe and attach available plans.
Yes. The restoration work will occur along about 160 feet of Honey
Creek and its banks. The purpose of the project is to return the
creek to a more natural state. The process will require the removal
of long culvert and fill associated with the culvert. The banks along
the stream channel will be re-graded and stabilized with rock and
vegetation.
3) Estimate the amount of fill and dredge material that would
be placed in or removed from surface water or wetlands and
indicate the area of the site that would be affected. Indicate
the source of fill material.
Of the total excavation (825 cubic yards), an estimated 300 cubic
yards of earth materials will be excavated from below the historic
ordinary high water (OHWM) from the historic stream channel and
its bank. In addition, approximately 20 cubic yards of streambed
material will be excavated from the current stream channel to create
a habitat pool in conjunction with LWD installation. The area
affected by this work (below the OHWM) is approximately 0.03
acres. This excavation would occur on the creek banks and also in
the creek.
Filling activities include: the placement of rock walls along the
stream banks for stability (67 cubic yards), installation of filter
gravel (107 cubic yards) and rip-rap (84 cubic yards) in the sediment

trapping area, and installation of spawning gravel (12 cubic yards).
Total fill will involve approximately 270 cubic yards of materials.
Fill material would be obtained from a local gravel pit in Kent or
Auburn.
4) Will the proposal require surface water withdrawals or
diversions? Give general description, purpose, and
approximate quantities, if known.
Work within the stream channel will require a temporary stream
by-pass. Sandbags will be used to dam the creek. The creek could
then be diverted through the construction site a couple of ways,
depending on creek conditions. A temporary pipe could be imbedded
in the sandbags and used to convey water through the construction
site. The second and most likely method would be to pump the
water around the construction site through a pipe. The stream
water will be conveyed through the pipe directly to the stream
channel, just downstream of the construction site. The water will
not be dispersed on the site.
5) Does the proposal lie within a 100-year floodplain? If so,
note location on the site plan.
No.
6) Does the proposal involve any discharges of waste materials
to surface waters? If so, describe the type of waste and
anticipated volume of discharge.
No.
b. Ground
1) Will ground water be withdrawn, or will water be
discharged to ground water? Give general description,
purpose, and approximate quantities, if known.
No.

2) Describe waste material that will be discharged into the
ground from septic tanks or other sources, if any (for
example: domestic sewage; industrial, containing the
following chemicals ....; agricultural; etc.). Describe the
general size of the system, the number of such systems, the
number of houses to be served (if applicable), or the number
of animals or humans the system(s) are expected to serve.
None.
c. Water Runoff(including storm water):
1) Describe the source of runoff (including storm water) and
method of collection and disposal, if any (including
quantities, if known). Where will this water flow? Will this
water flow into other waters? If so, describe.
Stormwater discharge from nearby development drains directly into
Honey Creek and will continue to do so after project completion.
Stormwater runoff during construction is expected to be minimal
since work will be conducted in the summer. However, any runoff
that does occur will be passed through filter fabric fencing before
being discharged into the creek. The existing storm drain and catch
basin that drains runoff from NE 27th Street drains into the concrete
ring in the Creek will be removed. A new storm drain and catch
basin will be constructed 20 feet south of the existing drain and will
route runoff from NE 27th Street to an energy dissipater near the
stream (refer to plans).
Erosion in the project area will be minimized by erosion and
sediment control measures. The stream restoration may deliver
some sediment to the creek on a short-term basis. Temporary
erosion and sediment control measures will be implemented. The
procedures include routing the stream around the construction
area, filter fencing, sand bagging, hydroseeding, and mulching over
exposed soils. After the banks are set back, the new slopes will be
vegetated with native species. Potential erosion will be limited by
doing the construction during the dry season.

Approximately one week prior to beginning construction activities
on the site, turbidity monitoring will be started approximately 100
feet upstream of the construction site. This data will be used to
establish background turbidity concentrations in Honey Creek.
During construction and for one week after construction has ended,
turbidity monitoring will be employed approximately 100 feet
upstream and 100 feet downstream of the construction site on
Honey Creek. Data will be evaluated on an on-going basis.
Downstream turbidity levels exceeding 5 NTU's above upstream
conditions will be considered indicative of construction site
impacts. Corrective actions will be implemented immediately to
eliminate the construction site source of turbidity to the stream.
Contingency actions for stream impacts will be outlined and
discussed in the pre-construction meeting with contractors.
Actions will include use of Baker Tanks, employing other
containment structures, disposing of turbid water into the sanitary
sewer, overland infiltration or spray irrigation of turbid water, and
placement of straw and silt fences. Pumps, hoses, straw, one
Baker Tank, and fencing materials shall be on-site during the
construction period.
2) Could waste materials enter ground or surface waters? If so,
generally describe.
As noted above, some sediment could enter Honey Creek during
construction. There is also the possibility that construction vehicles
could leak small amounts of petroleum products onto the ground
during routine operations. Construction equipment will be inspected
daily for leaks.
d. Proposed measures to reduce or control surface ground, and
runoff water impacts, if any.
A temporary erosion and sediment control plan and best management
practices will reduce the erosion and filter the sediment during
construction. This plan will utilize filter fences, hydroseeding, straw
mulching over exposed areas, and flagging of sensitive areas. In addition,

the project activity will occur during the dry season. Excavated areas and
side slopes will be stabilized with vegetation. The vegetation should
provide long-term benefits to the stream in terms of erosion control and
habitat protection. Construction best management practices (BMP's) will
be used to minimize the potential for accidental spills of fuel or oil from
heavy equipment during construction.
Approximately one week prior to beginning construction activities on the
site, turbidity monitoring will be started approximately 100 feet
upstream of the construction site. This data will be used to establish
background turbidity concentrations in Honey Creek. During
construction and for one week after construction has ended, turbidity
monitoring will be employed approximately 100 feet upstream and 100
feet downstream of the construction site on Honey Creek. Data will be
evaluated on an on-going basis. Downstream turbidity levels exceeding 5
NTU's above upstream conditions will be considered indicative of
construction site impacts. Corrective actions will be implemented
immediately to eliminate the construction site source of turbidity to the

RIPARIAN RESTORATION PLAN FOR
THE DEVIL'S ELBOW LIFT STATION REPLACEMENT
(PHASE 2: HONEY CREEK RSTORATION PROJECT)
1.0 PROJECT SUMMARY
The City of Renton removing a 54-inch diameter 98-foot long culvert from
Honey Creek and restoring and stabilizing the banks. The creek restoration in-
eludes approximately 170 linear feet of Honey Creek in Renton,Washington
(shown on Figures 1 and 2). This report describes the elements of the restoration
plan for the riparian stream banks.
The Devil's Elbow site is located west of the unimproved intersection of NE 27th
Street and 120th Place SE in the City of Renton. The site is relatively flat,but
slopes steeply along the banks of the creek and to the east and west. The vegeta-
tion of the Devil's Elbow site consists of several deciduous tree species with an
. understory of scrub-shrub and herbaceous plants, including several exotic spe-
cies.
1.1 Regulatory Background and Permits
Honey Creek is not regulated under the City of Renton Shoreline Master Pro-
gram;environmental impacts are regulated through the City of Renton
Entiironmrntal Ordinance (SEPA). Clearing within 25 feet of the edge of the
stream or 15 feet from the top of bank is regulated under the City of Renton Land
Clearing and Tree Cutting Ordinance (Ordinance No. 4219, City of Renton Mu-
nicipal Code).
Washington State, through the Department of Ecology (DOE), has authority to
issue Temporary Water Quality Exceedance Approval. Hydraulic Project Ap-
proval (HPA) pciutits for work within a stream channel arc issued through the
Washington State Department of Fish and Wildlife (WDFW).
•
The Muckleshoot Indian Tribe, King County DNR, WDFW, and the City of Ren-
ton have worked cooperatively to identify strategies to improve Honey Creek.
Under Section 404 of the Clean Water Act, the US Army Corps of Engineers
(Corps) and the US Environmental Protection Agency (USEPA) have joint
authority over waters of the United States, including streams and wetlands.
These agencies regulate the discharge of dredged and fill materials into waters of
the United States through the Corps permitting process.

1.2 Impacts
The City of Renton proposes to divert Honey Creek to remove the 54-inch culvert
and concrete walls and install a sediment trap,LWD (logs and root wads),bank
vegetation, and riprap (photos 1 and 2). Temporary impacts may include small
quantities of sediment entering the creek during Bearing and grading, and
clearing of vegetation. No permanent impacts associated with development of
the site are expected.

2.2 Description of the Overall Project
The Devil's Elbow project consists of two phases,which are proposed to occur
almost simultaneously. Phase 1 involves removal and replacement of the lift
station. Phase 2 is designed to improve fish passage and habitat with the fol-
lowing:
• removing the 54-inch culvert
• daylighting the channel
• removing the concrete walls along the culvert
• installing riprap and vegetation for bank stabilization
• installing large woody debris for habitat
• joint planting in the riprap for fish cover
• removing invasive plants
• planting native plants for habitat
3.0 ECOLOGICAL ASSESSMENT OF CREEK TO BE IMPACTED
The project includes approximately 170 linear feet of the Devil's Elbow reach of
Honey Creek. Maps of the project site and the restoration plan are included in
conks scientific&Servicaa Inc 2 Area 17.19915
this report. A summary of the creek and bank areas and the proposed impact is
given below.
3.1 Existing Water Regime
Honey Creek is a 1.2-mile long tributary of May Creek, which drains into Lake
Washington approximately 1 mile northwest of the site. In the Devil's Elbow
Reach,Honey Creek flows to the northwest through a narrow, steep-walled val-
ley.
On the Devil's Elbow site,water flows approximately 100 feet through the 54-
inch culvert and empties into a concrete ring structure south of the NE 27th
Street culvert (see photo 3). Two additional culverts, 12-inch and 18-inch, empty
into the concrete ring structure from stormwater to the south and north,respec-
tively. Water then flows from the concrete ring structure at the downstream end
of the 54-inch culvert (photo 6) under NE 27th Street through a 60-inch culvert
(photo 1). Considerable instream debris produce several elevation drops from 2
to 2-1/2 feet, creating fish barriers upstream of the culverts. Sedimentation in the
culverts may prevent fish passage in some areas. The steep-sloped walls along
Honey Creek fail frequently contributing to sediment loading in the creek. In-
tense development surrounding the creek has increased peak stormwater flows
and frequencies, increasing erosion and incision into the creek.
3.2 Existing Vegetation
Vegetation growing upstream of NE 27th Street includes bigleaf maple (Acer
macrophyllum), red alder (Alnus rubra), Silica willow (Salix sitchensis),Pacific wil-
low (Salix lucida var. lasiandra), Himalayan blackberry (Rubus procerus),
salmonberry (Rubus spectabilis), and reed canarygrass (Phalaris arundinacea).
Vegetation downstream of NE 27th Street consists of Himalayan blackberry,
Japanese knotweed (Polygonum cuspidatum), redstem dogwood (Cornus sericea
ssp. sericea), reed canarygrass, piggyback plant(Tolmeia menziesii), deer fern
(Blechnum spicant), and mosses. Fxotic plant species include Himalayan black-
berry,Japanese knotweed, and reed canarygrass.No endangered, threatened, or
sensitive species have been found or identified on the project site (Washington
National Heritage Program, 1991).
3.3 Existing Fauna
Previous stream survey and inspection work conducted by RH2 and King
County indicate that Honey Creek is utilized both up and downstream of the
culverts by cutthroat trout. Coho salmon have been stocked in the stream at
times,but no evidence of their survival exists to date. Adult salmon utilize May
Creek, to which Honey Creek is a tributary. The fish that now live in the Devil's
Conks Scientific services.inc. 3 Anvil 17.199X
cedar, redstem dogwood and rose. The existing vegetation is Japanese knotweed
to the west (photo 8) and blackberry to the east(photo 9).
The first step in restoring the native vegetation will be removing existing exotic
and invasive vegetation;herbicide will be applied to invasive species whenever
possible. The banks will then be heavily planted so that returning invasive and
exotic species will be crowded and shaded out. Native species were selected on
the basis of their presence at other less disturbed locations along the creek, as
well as their erosion prevention characteristics.
4.2 Goals and Objectives for Riparian Restoration
• Improve the fisheries habitat characteristics of the site via bank
restoration and stabilization,planting, and/or in-stream habitat
features.
• Re-establish a predominace of native plants in the project area.
4.3 Proposed Performance Standards and Monitoring
Performance standards, or success criteria, are proposed for the Devil's Elbow
site to achieve the riparian restoration goals and objectives. Performance stan-
dards, listed below,will have to be accepted by regulatory agencies before they
can be finalized.
• Development of layers of scrub-shrub and forested communities
with sufficient density (percent cover) and canopy development to
provide bank stabilization and shading of fish runs.
• Establishment of minimum of 80 percent plant cover by native
plants with not more than 15 percent of the cover consisting of ex-
otic and/or invasive species in the restoration areas. Exotic and
invasive species may indude,but are not restricted to,the follow-
ing: reed canarygrass, non-native blackberry, and Japanese
knotweed.
The performance standards will aid in determining the success of the restoration
project and will ensure that the restoration goals have been achieved. Monitor-
ing is an important part of the restoration sequence and ensures that the
performance standards are met. Regulatory agencies determine the timing of
monitoring. Monitoring should consist of the tasks listed below:
• Monitor vegetation characteristics (community type, species pres-
ence-and percent cover) of the restoration areas to determine if
habitat type and density goals are met. Recommended methods for
long-term monitoring of vegetation status include establishing
permanent transect lines, sample plots, and photo stations.

4.4 Hydrology
The planting design is based on the estimated hydrologic characteristics that
will be achieved after excavation and bank reconstruction. The stream varies in
depth and velocity across the year with as much as 60 CFS in the winter and 1
CFS by late August. Plantings have been selected based on their tolerance of
depth, frequency, and duration of inundation. Most plants have specific re-
quirements for these hydrologic characteristics (Cooke and Azous 1997,Taylor
1993).
4.5 Soils and Grading
Earthwork will be necessary during construction and renovation of the restora-
tion area. The removal of the 54-inch culvert and the concrete walls will require
bank regrading. A 6- to 12-inch deep filter layer of drainage gravel under 18
inches of riprap will be installed to filter sediment, withstand high velocity
stormwater, and withstand maintenance dredging of sediment. A riprap-lined
sediment collectin area will be created to the south of the road. The final con-
struction plan will be designed to create stable banks promoting fish habitat and
passage. Care will be taken during excavation to minimally disturb the steep
creek slopes as well as the emergency sewage storage pipe that lies parallel to the
creek.
Soil will be added to the upland (old lift station) after removal of the building
and underground vault. A layer of top soil 12 to 18 inches thick will be applied
to the lift area and where the existing gravel road will be restored to Creek bank
vegetation. The lift station hole will be filled in and soil placed in and over the
entire area. Then the lift area will be graded level.
4.6 Plants
Scrub-shrub and forested habitats were selected for the restoration design to re-
place and enhance lost communities. See attached plan sheet. Reference plant
communities were examined using less disturbed Creek reaches in order to de-
velop the plant list. The layout of the plant communities in both the Creek bank
and old lift station areas was designed to maximize interspersion of species, pro-
vide bank stability and shading for fish runs while considering the hydrologic
requirements of the plants. Exotic invasive plant species will be removed prior
to planting. Species to be used in the plantings are listed in Table 1.
Sitka willow and redstem dogwood stakes will be joint planted between the
riprap to provide cover and increased bank stability. The area upslope from the
riprap to the top of the bank will be a shrub community consisting of beaked ha-
zelnut, thimbleberry, and salmonberry. The steep 13/4:1 slope requires the
shrubs to be planted as stakes rather than pocket plantings. The upland on the
north side of the creek will be planted in beaked hazelnut to create shading. The
site of the old lift station south of the creek will be planted in large trees includ-
ennke Scierrtlec Services.Inc 6 Atr it 17.199N
planted within the riprap will be obtained at a length sufficient to penetrate up to
30 inches of riprap and filter to root in native soil. See Planting Schedule.
The planting sequence for the restoration will be to plant the trees and shrubs
first and then the herbaceous plants. It is expected that the planting will occur in
the fall of 1998. The single exception involves the availability of certain species.
Shrub species are supplied as bare root material during dormancy and in con-
tainers during the active growing season. Deciduous trees are supplied as bare
root during dormancy or in containers during the growing season. Evergreen
trees are generally supplied year-round as balled and burlapped or containerized
specimens.
4.7 Construction Management
The project biologist should be present on site during the various implementa-
tion phases of the creek restoration plan. It is always necessary to make field
adjustments to a planting plan as well as to supervise the planting of nursery
stock. In addition, it is important that the biologist examine and approve the
plant material before it is installed.
4.8 Watering
Plant material must have adequate water after installation. This is often the most
crucial component in ensuring the success of any wetland mitigation project.
There are several components of the design that can assist in the establishment of
plantings, especially during the critical phases. By planting during the fall or
early spring when the plants are in their hibernation phase, the plants' initial
need for water is decreased. Planting during this time period, typically the rainy
season, provides a natural source of water. Artificial watering will be necessary
during any spring installation and throughout at least the first growing season.
Hydrologic monitoring of this area will allow for an accurate determination of
the water needs of the plantings. Unlike the creek bank plantings, upland areas
are more likely to requfre additional water. Successful establishment of the up-
land plantings can be encouraged by planting as early as possible in the dormant
season in order to take advantage of the winter rains.
4.9 Landscape Maintenance
The objective of this restoration project is to stabilize the banks and improve fish-
eries habitat characteristics and fish passage through the Devil's Elbow reach of
Honey Creek. The only maintenance that would be required once the riprap is
installed and the creek banks and old-lift station site have been planted is re-
moval of weedy species. Exotic and invasive species, such as Japanese
knotweed, non-native blackberry, and reed canarygrass should be hand weeded
from the newly planted areas for two years after the installation. This will be
t nnke Scientific Service.Inc 8 Awn 1?.1990T
monitored accordingly. Preparation of a detailed monitoring plan in the final
restoration report will address any landscape maintenance necessary for the suc-
cessful completion of the restoration plan.
Mowing should be done only in the hydroseeded areas within the restoration
site. Any trees or shrubs that die over time should be left in place to provide ad-
ditional wildlife habitat,unless they are aesthetically objectionable or pose a
safety threat.
4.10 Site Protection
The creek will need to be sandbagged to divert the flow around the construction
site during the stream restoration phase. A pipe through the construction site
will divert stream flow, or the creek will be pumped to the downstream side to
the 60-inch culvert, depending on creek conditions. Any fish remaining in up-
stream pools will be removed and relocated downstream of the culvert. The 54-
._ inch culvert and the concrete wall can then be removed and riprap installed
without risk of sediment, erosion, or machinery affecting fish populations.
Orange barricade fencing will also be placed along the edges of the site to protect
the restoration area from encroachment during construction. Signs can also be
placed on the perimeter of construction areas to indicate the presence of the res-
toration area.
Earth work operations will be scheduled during dry weather to avoid erosion
Hydroseeding would be installed after final grading, or after installation of
scrub-shrub and forested communities is completed. Hydroseed mixes will be
determined during the final design stage and will be compatible with native Pa-
cific Northwest plant communities. Hydroseeding would include wood mulch
and a tackifier to prevent erosion of soil and seed. If hydroseeding occurs too
late in the fall to ensure prompt seed germination, erosion blankets should be in-
stalled after the earthwork is done and planting is completed.
Any topsoil used in the buffer enhancement area should be applied during the
dry season as well. This will minimize erosion and subsequent sedimentation of
adjacent wetland areas.
4.11 Maintenance and Contingency Plans
This section will be completed for the final restoration report.
4.12 Implementation Schedule
Implementation of the Honey Creekreek restoration phase of the project is ex-
pected for the summer and early autumn of 1998. Construction times are based
on a fisheries window from approximately June 15 to September 15, 1998 when
conk*Sdantifia Servics9.Inc 9 April 17.199X
spawning runs will be minimally impacted. Phase 1 lift station removal is
scheduled for June through November 1998 overlapping the Creek restoration
phase.
Ideally, restoration should be done in either the fall or early spring when plants
are in hibernation and are most hardy for transplanting. Planting during this
time will take advantage of winter and spring rains and will maximize the op-
portunity for the successful establishment of plants. Early spring or fall planting
will also decrease the cost of plant materials because bare root plants may be
used. Planting later in the spring will require use of the more expensive balled
and burlapped or container-grown material as well as regular supplemental wa-
tering.
Earth work should be done during dry weather to minimize the risk of erosion
and sedimentation. This is especially important on this site as the banks along
the creek are very steep and susceptible to erosion and mass wasting. It may also
be difficult to impossible to move the soils during a wet period because the ma-
chinery may not be operable.
