General Description: 2 of 23 \\$NDS\.RAPHAEL_SYS.RH2\DATA\REN\196-024\SEPA2.DOC 05/07/98 SEPA CHECKLIST C� o Honey Creek Stream Restoration at Devil's Elbow ♦ 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, 3 of 23 \\$NDS\.RAPHAEL_SYS.RH2\DATA\REN\196-024\SEPA2.DOC 05/07/98 SEPA CHECKLIST ' Y per Honey Creek Stream Restoration at Devil's Elbow ;; ` Environmental Checklist ♦ ♦ 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 J P 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.) . C.

General description of the site (circle one): Flat, rolling, hilly, steep slopes, ountainous, other b. What is the steepest slope on the site (approximate percent slope)? Honey Creek is located within a narrow, confined valley. The valley walls are at an approximate 30-60 percent slope. c. What general types of soils are found on the site (for example, clay, sand, gravel, peat, muck)? If you know the classification of agricultural soils, specify them and note any prime farmland. 5 of 23 \\$NDS\.RAPHAEL_SYS.RH2\DATA\REN\196-024\SEPA2.DOC 05/07/98 SEPA CHECKLIST \,(SY o Honey Creek Stream Restoration at Devil's Elbow ♦ ♦ Environmental Checklist ru INTO 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 6 of 23 \\$NDS\.RAPHAEL_SYS.RH2\DATA\REN\196-024\SEPA2.DOC 05/07/98 SEPA CHECKLIST 0� Honey Creek Stream Restoration at Devil's Elbow Ef:♦ ♦ Environmental Checklist ru 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 7 of 23 \\$NDS\.RAPHAEL_SYS.RH2\DATA\REN\196-024\SEPA2.DOC 05/07/98 SEPA CHECKLIST .(cY o Honey Creek Stream Restoration at Devil's Elbow ♦ ♦ Environmental Checklist 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 yes, describe 8 of 23 \\$NDS\.RAPHAEL_SYS.RH2\DATA\REN\196-024\SEPA2.DOC 05/07/98 SEPA CHECKLIST Honey Creek Stream Restoration at Devil's Elbow Environmental Checklist♦ ♦ ..0 - >NT°� 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 9 of 23 \\$NDS\.RAPHAEL_SYS.RH2\DATA\REN\196-024\SEPA2.DOC 05/07/98 SEPA CHECKLIST Honey Creek Stream Restoration at Devil's Elbow ♦ . Environmental Checklist ru 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. 11, 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.

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. 11 of 23 \\$NDS\.RAPHAEL_SYS.RH2\DATA\REN\196-024\SEPA2.DOC 05/07/98 SEPA CHECKLIST p� Honey Creek Stream Restoration at Devil's Elbow ♦ ht. ♦ Environmental Checklist ..0 Approximately one week prior to beginning construction activities on the site, turbidity monitoring will be started approximately 100 feet upstream of the construction site.

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.

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. Cnnke Scientific Services Inc 1 Aril 17.1991E 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. 2.0 PROJECT DESCRIPTION 2.1 Responsible Parties Devil's Elbow is owned by the City of Renton. The project manager and contact staff at the City of Renton for the project is John D. Hobson P.E. The address and phone number are as follows: John Hobson.P.E. Wastewater Utility 200 Mill Avenue South Renton,Washington 98055 425-277-6179 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. • Cmb Scientific Services. 0 Anvil 17.199N 5.0 REFERENCES Cooke,S.S., and Azous, A. 1997.

Air Impacts: Minor, temporary impacts to air quality can be anticipated during construction of the proposed project. Impacts during construction could include dust from disturbance of exposed soils and emissions from construction equipment. As a part of the construction documents, the applicant's contractor shall be required to keep dust to a minimum by keeping exposed soils moistened. All vehicles and equipment will meet federal, state, and local emission requirements. Mitigation Measures: No further mitigation is recommended. Nexus: N/A 3. Water Impacts:. During removal of the existing culvert and restoration of the stream bed, Honey Creek will be rerouted through a temporary pipe or pumped around the construction site to minimize construction impacts to the water. Mitigation Measures: One week prior to construction, monitoring will take place to establish background turbidity in the creek. During construction, monitoring will take place approximately 100 feet upstream and downstream of the construction site. If downstream turbidity levels exceed 5 NTU's above upstream conditions,then construction will stop and corrective action shall take place to eliminate the source of the turbidity. Nexus: N/A 4. Transportation Impacts: The construction is taking place in Honey Creek adjacent to a portion of NE 27th Street which is not open to public vehicles. Impacts to traffic would be limited to the delivery and removal of construction materials to the project site by dump trucks. The dump trucks will make approximately 90 trips over a five month period. All vehicle trips will take place during the working hours of 7 AM to 5 PM. Mitigation Measures: No further mitigation is recommended.. Nexus: N/A E.

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. oar--16r11,Al C>S,rCY 0 Honey Creek Stream Restoration at Devil's Elbow Environmental Checklist ♦ ru� � ♦ seP ENVIRONMENTAL CHECKLIST A.

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 6 of 23 \\ENDS\.RAPHAEL_SYS.RH2\DATA\REN\196-024\SEPA2.DOC 05/07/98 SEPA CHECKLIST ,V i p Honey Creek Stream Restoration at Devil's Elbow U �s Environmental Checklist N 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.

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 yes, describe 8 of 23 \\ENDS\.RAPHAEL_SYS.RH2\DATA\REN\196-024\SEPA2.DOC 05/07/98 �� SEPA CHECKLIST COTY3 Honey Creek Stream Restoration at Devil's Elbow Environmental Checklist 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 9 of 23 \\ENDS\.RAPHAEL_SYS.RH2\DATA\REN\196-024\SEPA2.DOC 05/07/98 SEPA CHECKLIST C�*�Y o Honey Creek Stream Restoration at Devil's Elbow ♦ 4 , Environmental Checklist ru �-N rod 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.

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. 11 of 23 r, \\$NDS\.RAPHAEL_SYS.RH2\DATA\REN\196-024\SEPA2.DOC 05/07/98 SEPA CHECKLIST U� p� Honey Creek Stream Restoration at Devil's Elbow �., Environmental Checklist • mil ant Approximately one week prior to beginning construction activities on the site, turbidity monitoring will be started approximately 100 feet upstream of the construction site.

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, 12 of 23 i! \\ENDS\.RAPHAEL_SYS.RH2\DATA\REN\196-024\SEPA2.DOC 05/07/98 SEPA CHECKLIST ��Y p Honey Creek Stream Restoration at Devil's Elbow G �'� Environmental Checklist • - _1\Try0 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.

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. Ccnke Sden Services Atoll Service Atll 17.199g 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. 2.0 PROJECT DESCRIPTION 2.1 Responsible Parties Devil's Elbow is owned by the City of Renton. The project manager and contact staff at the City of Renton for the project is John D. Hobson P.E. The address and phone number are as follows: John Hobson.P.E. Wastewater Utility 200 Mill Avenue South Renton, Washington 98055 47.5-277-6179 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. Conks Scientific Services.hoc 5 Ateil 17.199K 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.
