The proposal is part of the East Side Green River Watershed Project Plan and will specifically address; Springbrook Creek flood control and habitat restoration. SEPA environmental review for the proposal was conducted as part of the East Side Green River Watershed Project Plan review completed in September of 1997. The storm water culvert will be aligned directly with Springbrook Creek and will provide a greater area of stream bed than the existing culvert configuration. As a result, the capacity of the creek will increase and the potential for flooding will be reduced. Habitat restoration aspects of the proposal include the revegetation of the stream bank and wetland areas surrounding the site with native plantings and the placement of spawning gravel on the creek bottom. The pr,)ject site is located within the Urban and Conservancy Elements of Springbrook Creek as designm,ited by the City of Renton's Shoreline Master Program. The proposal is considered a local utility Find is allowed in both the urban and conservancy zones. In addition, the subject site is surrounded by category 2 and 3 type wetlands as indicated in the Wetland Delineation Report prepared by Jones & Stokes Associates, Inc. submitted with the application. The replacement of an existincl structure within wetland areas is considered an exempt activity from the Wetland Regulations (RMC ::section 4-3-110G1.c). The installation of the box culvert will require the removal of the existing arch culverts as well as the excavation of sediment near and around the culverts. The box culvert, 30 feet wide by 10 feet high, will be installed on top of pile and pile cap supports. Rip-rap and stream bed gravel will be placed around the piles below the water surface level to eliminate the potential for erosion or scour. In addition, the placement of cofferdams approximately 40 to 50 feet upstream and downstream will be necessary in order to isolate the construction area. The cofferdam will divert the stream flow to two 48 inch temporary pipes which will bypass the work area to the west. Other components of the project include the placement of steel sheet pile walls at the four corners of the new culvert and the planting of native shrubs behind the sheet piles. After channel banks have been recontoured and topsoil replaced, native shrubs will be planted and the pro.iect area will be hydroseeded with a wetland or upland mix. Plant species include sitka willow, red-osi'.w dogwood, red elderberry and black twin-berry for areas along the bench adjacent to the low flow channel and red elderberry, common snowberry and indian plum at higher elevations outside of the wetlands. The revegetated area will total approximately 7,550 square feet and will replace areas currently dominated by reed canarygrass. The co istruction of the project is proposed to begin August 4, 1999 and will be completed by September 30, 1999. The box culvert will be installed one half at a time. Erosion will be minimized SME.DO(.\ by obse rving standard sediment and erosion control practices such as installing silt fencing, straw bails and stabilized construction entrances.

Said development is proposed to be within and/or its associated wetlands. Any person desiring to express his views or to be notified of the action taken on this application should notify the City of Renton Development Services Division, Renton Municipal Building, 200 Mill Avenue S., Renton, Washington 98055 in writing of his interest within thirty (30) days of the last publications of this notice. Publication dates of this notice are and U:\AQUYNN\1999\65290\MASTERAP.DOC\AQ • CONSTRUCTION MITIGATION DESCRIPTION Proposed construction dates: August 4, to September 30, 1999 Hours of Operation: Construction will take place between 8:00 AM and 5:00 PM. However, due to a likely aggressive work schedule, construction will probably extend into the evening hours and Saturdays. Proposed hauling/transportation routes: Trucks will likely access the site from Grady Way to Lind Avenue South and then turn west onto SW 27th Street(when approaching the site from I-405). When approaching the site from SR-167, trucks will probably take the SW 43rd Street exit, turn north onto Lind Avenue SW and then turn west into SW 27th Street. Measures to be implemented to minimize dust, traffic and transportation impacts, erosion, mud, noise and other noxious characteristics: To minimize traffic impacts, two lanes of traffic will be maintained at all times during construction. Erosion will be minimized by observing standard sediment and erosion control practices such as installing silt fencing, straw bails and stabilized construction entrance. To minimize noise impacts, construction will not take place late into the evening and early morning hours. Because the site is not in a residential area,excessive noise should not be a significant problem. tea'=LOPr^.ENT CITY OF RENTON MAR 1 1 tS9 RECEIVED H:\DI V ISION.S\UTILITIE.S\DOCS\I999\FILETWO\99-151 A.DOC\AQ\tb PROJECT NARRATIVE Project Name, Size and Location: SW 27th Street Culvert Replacement Project Zoning designation of site and adjoining properties: HI Current use of the Site: The project site consists of a culvert crossing at SW 27th Street which is a four lane road over Springbrook Creek. The roadway currently supports car and truck traffic in an urban, light industrial setting. Springbrook Creek, a tributary to the Black River, flows under the roadway via twin, side-by- side corrugated metal arch culverts each 10.7 wide feet by 6.9 feet high. Flows through the culverts are in the range of 3-4 cubic feet per second (cfs) during the summer construction season. There are several utilities that run under the road including gas, power, phone,water and sewer. Special site features: The project is located on Springbrook Creek. Several wetlands are in the vicinity of the project as shown on the wetland delineation map attached to the Wetland Delineation Report which is enclosed with this application. The project is located within the 100-yr. floodplain of Springbrook Creek. Statement addressing soil type and drainage condition: Soil information can be found in the geotechnical report enclosed with this application. Please note that the drawings of the proposed culvert shown in the geotechnical report are outdated and don't reflect the current design which is on the exhibits attached to the Shoreline Permit. Proposed use of the property and scope of the proposed development: Project work consists of replacing existing twin metal arch culverts with one 3-sided precast concrete box culvert. The box culvert would be 30-feet wide and 10-feet high and supported on cast-in-place concrete pile cap and concrete piles. A short, approximate 2.5-foot high, cast-in-place ponywall would be placed on the pile caps to support the box culvert and provide a clear height of 10-feet. The piles would be 14 inch square, approximately 40-feet long and on about 3.7-foot spacing. Some rip-rap would be placed around the pile cap below the water surface level to eliminate the potential for erosion or scour. The box culvert would be aligned directly with Springbrook Creek and would provide a wider stream bed and greater area of stream bed than the existing culvert configuration. Installation of the box culvert would require excavation of sediment near the existing culverts; excavation of fill material around the arch culverts; and removal of the arch culverts. Piles and pile caps would be placed and the box culvert installed on top of these supports. Over excavation of sediments, fill and native material would occur to allow construction of the box cul kgg 6fliprap 'and stream bed gravel. CITY OF REt1 MAR 11 1399 RECEIVED Page 2 To maintain a minimum of two-way traffic on SW 27th Street, the box culvert will be installed one-half at a time. The south half of the culvert would be installed first. Steel sheet piles would be installed along the roadway centerline to allow excavation on the south half while routing on the north half. Sheet piles would also likely be used along both sides of the new culvert for shoring the excavation. The box culvert construction would require placement of a cofferdam approximately 40 to 50 feet upstream and downstream of the existing culvert openings to isolate the construction area. Cofferdams would be placed with construction equipment accessing the site by temporary access along the west side of the creek. The cofferdams would allow for diverting the stream flow around the construction site and for dewatering of the site. Stream diversion would occur by placing two, 48-inch temporary pipes bypassing the construction site to the west. Placement of the diversion pipes would require digging the channel banks to allow the pipe to intercept stream flow and allow for gravity flow of water around the project site. Sheet piles and/or additional cofferdams would be installed along the bank edge at the upstream and downstream cofferdam to protect the stream water quality while digging the trench in the streambanks. The sheet piles/cofferdams would be removed after the trench is complete and the diversion pipe is in place. The trench would continue through the SW 27th Street roadbed on the west side of Springbrook Creek to allow for gravity flow of water around the project site. Dewatering will be required because of the high water table throughout the project area and will necessitate dewatering wells and pumps. Other components of the project include placing steel sheet pile walls parallel to the box culvert at the four corners of the new culvert. The sheet piles would extend approximately 15 to 20 feet beyond the end of the culvert for the purpose of retaining the embankment slope. Native shrubs would be planted behind the sheet piles. After channel banks have been recountoured and topsoil replaced, native shrubs would be installed in the project area. Plants that would be planted along the bench adjacent to the low flow channel include Sitka willow, red-osier dogwood, red elderberry and black twin-berry. Shrubs planted on higher elevations outside of the wetland would include red elderberry,common snowberry and Indian plum. The total area planted would be 7,550 square feet which represents an area currently dominated by reed canarygrass. Shrub plantings would be placed approximately 6 feet on center and all areas would be hydroseeded with a wetland or upland mix. SEPA review for this project was completed as part of the East Side Green River Watershed Project Plan (ESGRWP)Alternative SC3 - Element 1 and EIS under LUA-95-205, ECF(Final EIS, Sept. 1997). Total estimated construction costs and fair market value of the proposed project: The total estimated construction cost is approximately$800,000. Estimated quantities and type of materials involved if any fill or excavation is proposed: 540 cy of fill material composed of riprap, spawning gravel, pile cap, pony wall and pilings. 590 cy of excavated material composed of existing metal arch culverts, sediment and native soil.

JARPA, Revised 12/9f', contact Ecology's Permit Assistance Center for latest version, 360/407-7037 Page 4 of 4 6. 0 escribe current use of the property, including structures: T le project site consists of a culvert crossing at SW 27th Street, a four lane road, over Springbrcok Creek. SW 27th Street supports car and truck transport in an urban, light industry setting. Springbrcok Creek, a tributary to the Black River in the Green River Watershed, flows under the road in twin side by-side corrugated metal arch culverts, each 10.7-feet wide by 6.9-feet high. Springbrook Creek flaws at SW 27th Street are generally 3-4 cubic feet per second (cfs) during the summer construct on season, but can increase to 40 cfs during a 24-hour period with summer rainfall (based on measurer rents taken at SW 27th Street 1993-1997). There are several utilities (gas, power, and phone lines) thet run underneath the road and above existing Springbrook Creek culverts. There is also a sanitary F.ewer that crosses under the culverts. E oth north and south sides of the roadway slope downward to the culvert openings. The existing culvert openings are mitered (sloped). These areas are covered in small rock (rip-rap) with vegetation intersper::,ed throughout. This vegetation adjacent to the roadway consists of Himalayan blackberry (Rubus discolor), scotch broom (Cytisus scoparius), sword fern (Polysticum munitum), reed canary grass (Phalaris arundinacea), and scattered young black cottonwood (Populus balsamifera ssp. trichocarpa) trees generally 6-to7-inches diameter at breast height, and some herbaceous plants. Il nmediately upstream and downstream of the culverts, Springbrook Creek has a low flow channel with a vegetated bench on either side of the channel. The low flow channel banks are generally vertical up to the adjacent bench. The bench above the low flow channel varies in elevation (approximately 1-2 feet) above the channel's surface water elevation (as observed in April 1998). The bench was likely formed when Springbrook Creek was widened and channelized into a linear feature for flood control. Vegetation along the bench is dominated by reed canarygrass, stinging nettles, and thickets of Himalayan blackberry along the upper outer edges of the bench where elevations are slightly higher. The wetland report submitted with this JARPA describes wetlands in the project area. There is a utility crossing approximately one-half mile downstream of the SW 27th Street Crossing that creates a high point in the channel, such that water levels even at low flows are about 1.5 to 2 feet del)p. l he majority of the project will be constructed on City-owned property. A drainage easement will be obtair ed to allow temporary access during construction for a small portion of privately-owned property located on the northeast corner of the site. When completed, the new culvert and any required appurtenances will be entirely located on City-owned property. Is the prIperty in agricultural land? No. 7a. Describe the Proposed Work. F'roject work consists of replacing the twin metal arch culverts with one 3-sided precast concrete box culv,;rt. The box culvert would be 30-feet wide and 10-feet high and supported on cast-in-place concrete pile cap and concrete piles. A short, approximate 2.5-foot high, cast-in-place pony wall would be placed on the pile caps to support the box culvert and provide a clear height of 10-feet. The piles would be 14 inch square, approximately 40-feet long and on about 3.7-foot spacing. Some rip-rap would be place around the pile cap below the water surface level to eliminate the potential for erosion or scour. The box ,:ulvert would be aligned directly with Springbrook Creek and would provide a wider stream bed, and grea:er area of stream bed, than the existing twin culvert configuration. Installation of the box culvert would require excavation of sediment near the existing culverts, excavation of fill material around the arch culverts, and removal of the arch culverts. Piles and pile caps would be placed and the box culvert installed on top of these supportings. Over excavation of sediments, ATTACHMENT TO JARPA 03/04/99 CITY OF RENTON PAGE 1 SW 27TH STREET CROSSING OF SPRINGBROOK CREEK,RENTON,WA fill, and n;:rtive material would occur to allow for construction of the box culvert, placement of riprap and streambei I gravel. T) maintain a minimum of two-way traffic on SW 27th Street, the box culvert will be installed one- half at a t me. The south half of the culvert will be installed first. Steel sheet piles will be installed along the roadw ay centerline to allow excavation on the south half while routing traffic on the north half. Sheet piles will Oso likely be used on along both sides of the new culvert for shoring the excavation. Tie box culvert construction would require placement of cofferdams (sand-filled bags) approxim itely 40- to 50-feet upstream and downstream of the existing culvert openings to isolate the construction area. Cofferdams would be placed with construction equipment accessing the site by temporar) access along the west side of the creek. The cofferdams would allow for diverting the streamflow around the construction site and for dewatering of the site. Stream diversion would occur by placing two 48-inch temporary pipes bypassing the construction site to the west. The proposed diversion system and cofferdams are shown on Figure 5. Placement of the diversion pipes would require digging the channel banks to allow the pipe to intercept stream flow and allow for gravity flow of water around the project site. Sheet piles and/or additional cofferdams would be installed along the bank edge at the upstream and downstream cofferdam to protect the stream water quality while digging the trench in the streambanks. The sheet piles/coffE rdarns would be removed after the trench is complete and the diversion pipe is in place. The trench we uld continue through the SW 27th Street roadbed on the west side of Springbrook Creek to allow for gravity flow of water around the project site. C ewatering will be required because of the high water table throughout the project area and will necessita:e dewatering wells and pumps. The dewatering system will have to be installed prior to the bulk of a<cavation in order to allow for a drawdown of the water table and stabilization of the soil. Pumped :lewatering water will be treated in a temporary sediment pond. Water from the sediment pond will flow t:y gravity into the two 48-inch diversion pipes. The sediment pond would be constructed in an upland location between Springbrook Creek and the wetland west of the creek and south of SW 27th '3treet(Renton inventory wetland W-12b). The sediment pond would measure 20 feet by 20 feet and would be several feet deep. Other components of the project include placing steel sheet pile walls parallel to the box culvert at the four corners of the culvert. The sheet piles will extend approximately 15 to 20 feet beyond the end of the culvert for the purposes of retaining the embankment slope. The top of the sheet piles would slope down from the culverts at a 2.5 H:1 Vslope. Native shrubs would be planted behind the sheet piles (see response to block 7c). C'ther work would include temporary construction access routes established on the west side of Springbrook Creek on both sides of SW 27th Street. Construction equipment required on the project site includes lackhoes, cranes, dump trucks, and loaders. Backhoes and loaders would use the temporary access rc ads to the culvert, temporary coffer dams, diversion system, and sediment pond during project construction. Femoval of the existing arch culverts would occur after Springbrook Creek flow has been diverted and the ;ite dewatered. Removal of the culverts would be done by temporarily relocating/supporting utilities, removing the SW 27th Street roadbed, removing fill material surrounding the culverts, and lifting the culverts out of their location onto a truck to be hauled away. Most of the fill would be disposed of at a City-approved upland location. The existing sediment in the creek bed may need to be disposed of at a landfill. :,ediment testing for total petroleum hydrocarbons (TPH) would be done to determine if sediment disposal.,vould be required at a facility permitted to receive such sediments (e.g., Cedar Hills). kfter the box culvert is installed and backfilled, banks and streambed would be graded to specified contours, the diversion pipes would be blocked, and the cofferdams removed to allow for ATTACHMENT TO JARPA 03/04/99 CITY OF RE VTON PAGE 2 SW 27TH STREET CROSSING OF SPRINGBROOK CREEK,RENTON,WA streamflow to return to Springbrook Creek. Sediment accumulation behind the upstream cofferdam would be removed by a backhoe reaching into the stream before the cofferdams are removed. The streambed will be returned to existing grades. Gradual lowering of a spillway notch in the upstream cofferdam would regulate the amount of streamflow and subsequent amount of scouring in the original channel location. The diversion pipes would be then be removed. Figures 2-5 included in this JARPA show the general arrangement of the culvert and pile supports; locations of the diversion pipe, cofferdams, and sediment pond; and temporary access road alignments. In summary, the sequencing of steps generally taken for site preparation to divert Springbrook Creek flow and dewatering of the project site are listed below. (Actual construction sequencing may vary slightly di.iring the preparation of construction bid documents as final designs are completed, and that may be )roposed by the construction contractor, but the sequencing will be structured to minimize sediment ition and introduction of turbidity plumes in the channel. 1) Construct temporary sediment pond and other temporary erosion control features including p acement of sediment fencing. 2) Trench is excavated across SW 27th Street for placement of the diversion pipe. Sheet piles aid/or cofferdams will be placed at channel edge at inlet and outlet point along Springbrook Creek to isolate creek from diversion trench and allow creek to continue flow in channel. 3) Place 48-inch diversion pipe in trench and backfill. Place filter fabric around exposed soil at trench inlet and outlet points along Springbrook Creek. 4) Femove sheet piles/cofferdams at inlet and outlet and connect diversion pipe to streamflow to divert stream. 5) Install downstream and upstream cofferdams. 6) Ii istall dewatering wells and pumps and piping to sediment pond and pipe from sediment pond to tl ie temporary diversion pipe. 7) E!egin installing temporary sheet piles around south half of roadway excavation area. 8) (:oncurrent with sheet pile installation, dewater the project site. Proceed with the south half of the culvert replacement project. After the south half is complete, the area would be backfilled and a t)mporary road installed. Traffic would be diverted to the south half and excavation could begin an the north half. 9) /after the entire culvert and streambed construction is completed, grade the banks and slopes to design specifications. Install erosion control fabric along exposed bank slopes. 10) Remove downstream cofferdam and the portion of the diversion pipe in the creek. Gradually I>wer spillway of upstream cofferdam to allow streamflow to return to restored Springbrook Creek channel. 11) Remove diversion pipe and complete the final regrade of the site and channel banks along the diversion pipe trench. Remove temporary sheet piles along the channel banks at the diversion pipe inlet and outlet. Install erosion control blankets at the restored inlet and outlet points along the channel banks. 12) I lydroseed area and install native shrub plantings. ATTACHMENT TO JARPA 03/04/99 CITY OF RE NTON PAGE 3 SW 27TH STREET CROSSING OF SPRINGBROOK CREEK,RENTON,WA 7b. Describe the Purpose of the Proposed Work. Tie primary purpose of the project is to increase the conveyance capacity of Springbrook Creek at the crossing of SW 27th Street in order to reduce upstream water levels and alleviate flooding. The existing corrugated metal arch culverts are undersized and currently restrict stream flow during high flow events causing upstream water to back up and cause flooding during high rainfall periods. Replacing the existing culverts with a 30-foot wide by 10-foot high box culvert would increase flow capacity and decrease upstream water surface elevations by approximately 2 - 3 feet (based on 100-year future land use cond tion flows). This is consistent with the East Side Green River Watershed Project Final Environm,mtai Impact Statement previously adopted by the City of Renton. Aneliorating fish habitat is also an important objective of this project. By widening the open area of the culvert, stream velocities will be reduced and fish passage through the culvert will be improved. In addition, installation of a 3-sided box culvert will allow for improvements to the existing stream bed by placing spawning gravel along the length of the culvert and increasing the area of gravel covered stream bed from he existing condition. Other fish habitat improvements include placement of instream root wads and planting native shrubs along the stream channel. 7c. Describe the Potential Impacts to Characteristic Uses of the Water Body...ldentify Proposed Actions to Avoid, Minimize, and Mitigate impacts, and Provide Proper Protection of Fish and Aquatic Life. The primary adverse impacts of the project will be temporary, related to construction, and include the following: Sediment Generated by Construction Activities. Sediment may enter the Springbrook Creek channel e s channel bed sediment is briefly disturbed during initial placement of the cofferdams as well as removal cif cofferdams after project construction is completed. Placement and removal of the diversion pipes ma/ also create some sediment delivery to the channel as the diversion pipe is placed within the banks of Springbrook Creek. Dewatering of the project site will require pumping water into a sediment pond and some residual sediment will likely remain in the water that is discharged back into the channel from the :sediment pond. C irect Disturbance of Streambed and Potential Salmonid Habitat. Removal of the existing twin culv?rts, dewatering of the project site, and placement of the new box culvert and enhanced streambe i will occur in the Springbrook Creek channel. However, fish habitat conditions in the channel are gene ally degraded, with poor spawning habitat (fine sediment in channel bed) and lack of riparian vegetation providing shaded cover. The total area of streambed between the two cofferdams which will be dewat gyred and where construction will generally occur is approximately 3,000 square feet (in addition to the arc a of the twin arch culverts where sediment has formed a "streambed" in the culvert bottoms). Temporary Disturbance of Wetland. The wetland which occurs on the low bench adjacent to Springbrook Creek would temporarily be disturbed by construction activities. No permanent loss of wetland <Irea would occur although access roads and placement of the diversion pipes would occur in approximately 1,300 square feet of the wetland. This wetland is dominated by reed canarygrass and the total amc unt of wetland area would increase in area after construction is complete, the ground surface is graded tc final elevations, and the area is replanted with native shrubs. Aleasures taken to avoid, minimize, and mitigate for project impacts include the following: Fox Culvert Design. Based on discussions with the Washington Department of Fish and Wildlife (NDFW) the culvert will be a 3-sided box culvert with a natural mixed gravel streambed. The culvert will also be directly aligned with the existing channel to minimize flow obstructions through the culvert. The culvert is also wider than the existing twin culverts to provide a more natural stream ATTACHMENT TO JARPA 03/04/99 CITY OF RE 4TON PAGE 4 SW 27TH S1 REET CROSSING OF SPRINGBROOK CREEK,RENTON,WA condition entering and exiting the culvert. This will also reduce velocities which will improve fish habitat and passage. Sediment Fence and Filter Fabric. Sediment fence will be placed in buffers surrounding the wetlands located off the main Springbrook Creek channel on the northeast and south sides of SW 27th ;:itreet. Filter fabric will be placed on exposed soil along the edges of the trenching required to place the diversion pipe at the upstream and downstream openings along the bank of Springbrook Creek to minimi:'e soil erosion and sediment entering the stream flow. if needed, a silt curtain would be installed at specific times in Springbrook Creek downstream of the downstream cofferdam as an added precaution to contain turbid plumes which may be generated during construction. Construction Timing. Instream construction will occur during the summer, specifically from August 1 through September 30, when streamflows and precipitation are low. The construction will occur during this period to protect anadromous fish during sensitive life history periods that may occur in this reach of; pringbrook Creek such as migration and early rearing. Sedimentation Pond. Dewatering of the project site between the cofferdams will generate sediment laden water during the dewatering process. This water will be pumped to a sedimentation pond located in an upland location next to the creek before being discharged back into Springbrook Creek. Recontouring of Springbrook Creek Channel Banks With an Increase in Wetland Area. After construction of the box culvert is complete and construction activity is complete along the banks and bench ad acent to the creek, ground elevations will be contoured to final grade. The low bench along the creek will be recontoured to pre construction conditions and will continue toward the culvert openings. Final graces will increase the amount of area expected to be wetland from the existing conditions by 250 square feet as a greater area of the surrounding ground surface will be at an elevation equivalent to the existing wetland. Recontouring of the banks would eliminate the temporary sedimentation pond, trenches for the diversion pipe, and the temporary access roads. Topsoil that was salvaged during construction of the sedimentation pond and trenches would be replaced and soil would be disked to decrease soil bulk density that would be compacted from construction equipment traffic. Revegetation With Riparian Plant Species. After channel banks have been recontoured and topsoil replaced, native shrubs would be installed in the project area. Plants that would planted along the bench adjacent to the low flow channel (the wetland adjacent to Springbrook Creek) include Sitka willow (Salix sitchensis), red-osier dogwood (Corpus stolonifera), red elderberry (Sambucus racemosa), and black twin-berry (Lonicera involucrata). Shrubs planted on higher elevations outside of the wetland would include red elderberry, common snowberry (Symphoricarpos albus), and Indian plum (Oemleria cerasifonnis). The total area planted would be 7,550 square feet which represents an area currently dominated by reed canarygrass. Shrub plantings would be spaced approximately 6 feet on center and all areas wo.ild be hydroseeded with a wetland or upland seed mix. Erosion control blanket would be placed along the channel banks adjacent to the creek to prevent soil loss into the creek. Benefits to Fish Habitat Conditions. The project is expected to provide a long-term benefit to fish in the project area by increasing the amount of streambed by 1,200 square feet over current condition::;, reducing stream velocities through the box culvert, improving riparian vegbtation conditions with the planting of native shrubs, and installing two rootwads along the channel banks downstream of the culvert. Two rootwads would be anchored into the channel bed to provide instream wood debris for resting and cover habitat. Mitigation Summary. No wetland loss will occur and an increase of 250 square feet of wetland area will be created from the project. In addition, 1,050 square feet of wetland currently dominated by ATTACHMENT TO JARPA 03/04/99 CITY OF RENTON PAGE 5 SW 27TH STREET CROSSING OF SPRINGBROOK CREEK,RENTON,WA reed canal/grass will be enhanced by planting with native wetland shrubs; 6,500 square feet of upland area currently vegetated with reed canarygrass and Himalayan blackberry will be revegetated with native upland plants. Fish habitat will be enhanced in Springbrook Creek by restoration of 3,800 square feet of streambec covered with spawning gravel (representing a net increase of 1,200 square feet of streambed). In additior woody debris will be added to the stream channel for resting and cover habitat for fish and riparian plantings will improve riparian vegetation along the portion of Springbrook Creek in the project area. Figure 6 shows the areas to be planted with native shrubs and the area of enhanced gravel streambec. • ATTACHMENT"TO JARPA 03/04/99 CITY OF REN''ON PAGE 6 SW 27TH STF,EET CROSSING OF SPRINGBROOK CREEK,RENTON,WA . *• j 40' GREENBELT • 1 6 EASEMENT r:?,..,".._I I t CV \1,..\,;i\;1,:):i,iiifi'••1s1I,. 1•,i,± ,:•,;, 11.4.4i16%44li.'1 00r,.;,'--iI1t•;I//,1,'.‘1.i14I\,A' „.. i\4/i,\..,,•T,. ..__ 1 W•11-i.1,\.TET S. .4.E..,,..M...*.T.FN T ,.o*. 44.z,..........‘44....,.........,.............*.41.6.,.........._ ....* 15 RECREATIONAL: / VOTER GAUC EASEMENT- / 4 / * k * RENTON #2LLC \ 111/41 l 1 _71i , WATER "A `'A / 1r P • ' ... _...4' * 3 * * ...--...- '- ``'• -°41olik ' ';" '.Ik I; -'''. ..--/ .. ••••• CORP •, •••••• ...•••"5-"".- . - 14%14sgunimuihomm...„Lli "---',,•:.•••=ec..4.-.:::-,. al"_,,.._ 15_,1- ._ 13 -s r....-,...,g, , ........ itIMMINEZEMPINIZI=IME:.- .----..,......._........ ....................___-,-,-„,„„,...._ - ---- .............. - 4,.. r...........1 , ______,___ ................„........ imi............._............,.... 1 ASpHAL r • • . __ 1 1 1 „,_.....--_________ 1--- • ' 1 1 Ach n' CONCRETE 1 I • I I Nar St' 27,I NEW 30' WIDEsr X 10' HIGH : 'ri I CONCRETE BOX CULVERT Ilk . , , CURB a. ---__ I • \--14;topl,..

DRAFT GEOTECHNICAL REPORT - SW 27"i STREET CULVERT REPLACEMENT RENTON, WASHINGTON 1.0 INTRODUCTION 1.1 GENERAL This report presents the results of the geotechnical engineering study completed by A GeoSciences Inc. (HWA) for the proposed SW 27th Street Culvert Replacem project in Renton, Washington. The project site is located in an industrial area s of Renton, and is shown on the Vicinity Map, Figure 1. The intersecting alig - s •'SW 27th reet and Springbrook Creek are shown on the Site and Explor. '•n Plans, Fjaxres 2 and 3. The existing and proposed culvert alignments are also sho o -se figures. 1.2 SITE AND PROJECT DESCRIPTION We understand that the C. • Rento plan, to pla e o 12: ' ch wide by 8:-inch high corrugated metal pipe (CMP) cu erts hat 'on su 'ac: wat r in Springb oo Creek from the sout• '•e e SW 27 -et '• the no side of he s reet.

Alternative ho •n Figures• and , consi s of: i : • 30-foot wide by 10-feet high (inside di - .ioni •oncr- e cul -rt. Al -rnat v- , shown on Figures 3 and 5, consists of a 31 • •t w d; by feet (i side diameter) concrete culvert that would handle the ma •rinu•r, ok re; flo . d a second, 30-foot wide by 4.7-feet high culvert thit w• • pr. id- ca.acit 'n storm, or heavy flow conditions. Each of the culverts will b. 20 f et 1 •:. The walls of the proposed concrete culvert(s) are anticipated to be a.•roximately 10 inches thick and the roof and floor will each be about 14 inches this. . Current design options that are being considered by R. W. Beck include a four-sided box culvert or a three-sided culvert with an open channel bottom. The culvert(s) will consist of either pre-cast concrete sections or a cast-in-place structure. We understand a three- sided culvert is preferred by the Department of Fisheries. Selection of the three-sided culvert or four-sided box culvert options for the replacement culvert(s) will be based, in part, on the most feasible construction methodology, cost, and anticipated performance. - - October 26, 1998 HWA Project No. 98032 1.3 SCOPE OF SERVICES AND AUTHORIZATION Our work was conducted in accordance with our proposal letter, submitted by HWA to R. W. Beck on March 6, 1998. Verbal authorization for the work was subsequently given by Mr. Michael Giseburt, project manager with R. W. Beck. The scope of work completed for this project included performing two exploratory borings at the site, performing laboratory testing, performing engineering analysis based on the conditions observed in our explorations, and providing geotechnical engineering recommendations for the proposed culvert(s). 2.0 FIELD AND LABORATORY INVESTIGATIONS 2.1 FIELD INVESTIGATION On April 1998, HWAperformed a subsurface ex Lora ' program t•. incl ded PP drilling two exploratory borings (designated BH-1 .nd BF-2) e advance• to •epths of 59 feet below the ground surface.

Standard Penetration Test (SPT) sampling was perfoa-me' g a -1 ch •ut-'de •'• eter split-spoon sampler and a 140-pound hammer. Du i n S 'T est, . sample is obtained by driving the sampler 18 inches into the soil w.th t e ha er --falling 30 inches. The number of blows required for each 6 inches of oenetrat', is recorded. The Standard Penetration Resistance ("N-value") of the soil is calm.' • -• as the number of blows required for the final 12 inches of penetration. • This resistance, or N-value, provides a measure of relative density of granular soils and the relative consistency of cohesive soils. Soil samples were classified in the field and representative portions were placed in airtight plastic bags. These soil samples were then returned to our laboratory for further examination and testing. The soils were classified in general accordance with the classification system described in Appendix A on Figure A-1. A key to the boring log symbols is also presented in Figure A-1. The boring logs are presented on Figures A-2 and A-3. The stratigraphic contacts shown on the individual logs represent the approximate boundaries between soil types. 98032.doc 2 HWA GEOSCIENCES INC. October 26, 1998 HWA Project No. 98032 2.2 LABORATORY TESTING Laboratory tests were conducted on selected samples obtained from our borings to characterize certain engineering and index properties of the project soils. Laboratory tests included determination of in-situ moisture content, plasticity characteristics (Atterberg Limits), and grain size distribution. In-situ moisture content test results are displayed on the exploration logs in Appendix A, as appropriate. Plasticity characteristics are presented in Appendix B on Figure B-1. Grain size distribution test results are presented on Figures B-2 and B-3. 3.0 GEOLOGIC AND SUBSURFACE CONDITIONS 3.1 GENERAL GEOLOGIC CONDITIONS Geologic information for the site was obtained from the G•ologic Al,' - t ' R' ton Quadrangle, King County, Washington (Mulline. ., D.R. 19. .

Along the SW 27th Street alignment, the alluvium i; ov: • by ill soil us-. to • struct the roadway. Directly below the roadway emb. • ent ill, co •ressl.le organic silts were observed overlying the alluvium. Approximate = feet of a surficial roadway fill was encountered in the site borings. The fill soils generally consisted of medium dense to very dense, slightly gravelly, silty sand. In our analysis, we assumed that the fill soils had a in situ unit weight of 130 pounds per cubic foot (pcf). These fill materials were placed during original construction of SW 27th Street and the development of the industrial park. The pavement consisted of 7 inches of asphalt over a negligible thickness of base course material. Organic silt was encountered below the fill to depths of about 17.5 feet (or 8.5 feet thick). Based on the surrounding topography, it appears that little organic silt material was removed during road construction. Below the organic silt, borings encountered interbedded sands, silty sands and silts which ranged from loose to medium dense to soft to very stiff. The alluvium extended to the full depth in each exploration. 98032.doc 3 HWA GEOSCIENCES INC. - October 26, 1998 HWA Project No. 98032 • 3.3 GROUNDWATER AND SURFACE WATER The Springbrook Creek flows north through the existing culverts. Surface water level readings taken in September 1998 indicate the water in the culverts was about 11/2 feet deep, or at Elevation 7.5 to 8 feet. Groundwater level readings taken during our exploration program indicate the groundwater is at approximately Elevation 3 feet. However, during drilling the groundwater level in the borings were not allowed to stabilize and consequently the water level during drilling is typically lower than the static groundwater level at the site. It is anticipated that surface water and groundwater conditions will change in respon e to rainfall, level of Springbrook Creek, time of year, and other factors. 4.0 CONCLUSIONS AND RECOMME TIO S 4.1 GENERAL Based on our explorations, the SW 27th Stree alig ent is and r ain by co hpre-sible organic silts that range from ab•. I- ation 1 eet o Elevation feet, o 8.5 feet thick. In our opinion, fu er consolid.,ion ,•f t : or.:nic mat rial may occ r if :dditional loads are applied • he materi . The .ilty an i and on•org nic silts (all v'- ) which underlie th- . ignment .re anti ip ed • pr-►vi• - : eat- sLppo than the organic material, providing the loads are well di nbut,d. We reconanen3 th ne s:ruc -s be 1e gn:i and . , structed on mat foundations founded on the mo a c•m?ete t 'lty sa f,s a d silts, or on pile foundations. Four-sided box culverts sr.oul be .u i po 1-d •n . • 'oundations. The organic silts should be overexcavated to ppr•xi ate i Elevation 2.5 feet and the overexcavations backfilled with compacted cnas ed r,,ck. e foundations should be used to support three-sided culverts. We anticipate that •se of strip footings to support the stem walls of a three-sided box would crest- : excessive load on the underlying soils and would result in large potential settlements. Foundations supported on strip footings would also be susceptible to scour. Consequently, strip footing foundations are not recommended. For a pile supported culvert, feasible piles types include auger-cast, driven timber piles, or driven pre-cast concrete piles. Piles should be embedded well into the underlying alluvial sands to support the design loads using skin friction and end bearing resistance. In order create a habitat conducive to fish, we recommend the four-side box culvert(s) be partially filled with bank run gravel or similar material. The culvert(s) may have to deepened to accommodate the extra 1 to 2 feet of material and maintain design stormwater flows. 98032.doc 4 HWA GEOSCIENCES INC. October 26, 1998 HWA Project No. 98032 Groundwater control will play a large role during construction with either mat foundations or pile foundations. For mat foundations, dewatering will be required to lower the" groundwater level so that excavations and subgrade preparation can be performed during relatively dry conditions. Pile foundations can be driven under wet or submerged conditions, but dewatering will still be required to cast concrete pile caps and stem walls. We anticipate rerouting Springbrook Creek using cofferdams and pumps, and then lowering the local groundwater level within the excavation using sumps and pumps. Wells • or well points may also be required depending on the type of culvert structure installed and the depth of the excavation. Construction dewatering will depend on the time of year, the level of Springbrook Creek, recent rainfall and other factors. Geotechnical recommendations for subgrade preparation, mat foundation port, pi e foundations, backfill placement and compaction, temporary excava •: s and grou ater control/dewatering are discussed in the following sections. 4.2 CULVERT STRUCTURE(S) 4.2.1 Mat Foundation Support • Subg-ade Pr•par,tion Based on the results of oi. exploration., co pr sibl: or.:nic .oils extend o approximately El• .tion o.5 f- - :el. t • c res ibl: soil., we anticip ks_ose to medium d- - silty sa i ds and -. urn .tiff.ilt ' 1 be -n•.unt-red. We anticipate the silty sand' and non-or:.ni c sil will .rovi•e adequate s p i ort •f the proposed culvert, providing the . : not nduly distur.-d d ring •;rade . - •aration. We anticipate that the weigh of - ew • n ctur• ill b- sl'.htl grea - han the weight of the soil replaced by the strictu - e r,cc mat,n• using . ne soil bearing pressure increase of 800 pounds per square fo• • .f) for desig o he -• vert structure (i.e. the structure and backfill should weigh • 801 ps mo e than the in situ soil it replaces). We recommend u ' g a mat foundation, or crushed rock pad, bearing directly on the loose to medium • - se silty sands and medium stiff silts to support the four-sided box culvert. The crushed rock working pad will help to minimize damage to the subgrade during placement of precast concrete culvert sections, or during placement of forms and steel reinforcing for the cast-in-place option. We recommend supporting the 10-foot high culvert (Alternative 1) and the 6.7-foot high culvert (Alternative 2), on a 2-foot (minimum) thick layer of crushed rock. For the 4.7-foot high culvert (also Alternative 2), we recommend using 3 feet of crushed rock and "floating" the structure on the organic silt; our calculations indicate that there is no increase in load for the 4.7-foot high structure, located as shown on Figure 5. The crushed rock pad should extend beyond each end of the box culvert a distance equal to the height of the pad (e.g. 2 feet on each end for a 2-foot thick pad). 98032.doc 5 HWA GEOSCIENCES INC. ' October 26, 1998 HWA Project No. 98032 Excavation and subgrade preparation should be observed by the geotechnical consultant. A geotextile fabric may be used below the crushed rock pad to provide a separation barrier between the structural fill and the loose, saturated subgrade soils. The geotextile will prevent the loss of aggregate into the subgrade and minimize upward pumping of fine grained soil. However, the use of a geotextile will not eliminate the need to overexcavate. Crushed rock for overexcavations and for the working pad should be placed and compacted as described in Section 4.3. 4.2.2 Pile Foundation Support If three-sided box culverts are used for the culvert replacement project, we reco d supporting the abutments, or stem walls, using pile foundations. Compare strip footings, pile foundations will provide more support if the subgrade •• efies duri seismic event, and the pile supported structure would be more ista t to poten ial scour, and will exhibit negligible differential settlements. Pile fo dations • d nsist of either auger-cast piles, or driven piles such as timber or : e-cast on .- e piles. The fallowing paragraphs present preliminary design reco , enda ions d i st. . ion methods, including potential pile embedments .nd dia -ters, '►r ea•h of the r: ommended pile types.

By maintaining pressure in the grout li - . • slokvl y extra ting :au:-r no .ster than an equivalent volume of grout is pump, • . con inuous co mn •,'c•• rete is formed. A single reinforcing rod can be installed fo - full ile length t r•.: the hollow-stem of the auger, and/or, a reinforcing ca; - an place in the column. The allowable ca city of auger-cast concrete piles at the site will vary with pile length and diamet . Axial capacity is based on skin friction resistance and end bearing resistance. For preliminary planning and estimating purposes, we anticipate a 24-inch auger cast pile could support an average skin friction resistance of 2.5 kips per liner foot of pile and a tip resistance of 10 kips per square foot. These allowable resistances include a factor of safety of 2.5 for skin resistance and 3.0 for tip resistance. Based on this estimate, a 24-inch auger-cast pile supporting an allowable design load of 65 tons (130 kips) would have to be approximately 40 feet long. Driven Piles—Timber and pre-cast concrete piles could also be used to support the proposed structure. Timber and pre-cast concrete piles can be easily driven into the relatively loose to medium dense sands that underlie the site using a steam or diesel impact 98032.doc 6 HWA GEOSCIENCES INC. October 26, 1998 HWA Project No. 98032 hammer. Timber piles are the cheaper alternative of the two but are usually limited to shorter lengths; 30 to 40 feet long timber piles are common, with longer lengths available at higher cost. A 12-inch to 14-inch timber pile can be expected to support an allowable axial capacity of approximately 1.5 kips per linear foot of pile (this includes a factor of safety of 2.0) if embedded sufficiently into the alluvial soils at the site. Based on this analysis, a 40-foot long pile will provide an allowable axial capacity of 30 tons, or 60 kips. If timber piles are sufficiently embedded below the groundwater surface, chemical treatment (creosote) is not necessary. However, if piles will be exposed to air for any period of time, we recommend they be treated to resist decay. Concrete piles can be cast in various lengths and diameters and are pre-stressed •' .teel reinforcing. We anticipate 14-inch square and 161/2-inch octagonal piles - support oads of approximately 2 kips per linear foot and 2.5 kips per linear foot .•ectively. t .sed on this analysis, a 40-foot long pile will provide allowable axial .. .acitie if, . ton (80 kips) and 50 tons (100 kips) per pile, respectively. The capaciti s per li• •.r oot iste. here include both skin friction resistance and end be. and . fact.r of safety .f 2.1. 4.2.3 Lateral Earth Pressure For the four-sided box cul vert founded on a a un•ati. , it s anticipates that the proposed struct alls will e r tra' ed ,ga' s rot.do i an. will have re .

The•- . ues hould :1•o be s:d f. three-sided box culvert walls. This recommendati. . -.um s :hat he sac. .- nd the subsurface walls will consist of properly c pmp; • st ct,irai ill, • .: •oes not include adjacent surcharge loads. If the below-gra le a wil be •ub'-cted to the influence of surcharge loading during construction, e.g. ex avators or semi-trucks, within a horizontal distance equal to or less than the height a walls, the walls should be designed for the additional loads. We typically a• me traffic surcharge loading is equivalent to a uniformly distributed load at the ground surface of 250 psf. Using this value, traffic surcharge loading within a distance less than the height of the wall could be determined using an equivalent fluid weight of 75 pcf applied as a uniform rectangularly distributed load over the height of the wall. During a seismic event, lateral earth pressures acting on below-grade structural walls will increase by an incremental amount that corresponds to the earthquake loading. A concomitant decrease in passive earth pressure also occurs. However, if at-rest earth pressures are used in design, a conservative structural design that can readily accommodate the temporary seismic overloading conditions generally results. Therefore, 98032 doc 7 HWA GEOSCIENCES INC. October 26, 1998 HWA Project No. 98032 it is our opinion that the dynamic incremental pressures from earthquake loading may be neglected if the below-grade structures are designed based on at-rest earth pressures. Lateral forces acting on the three-sided culvert will be resisted by the lateral stiffness of the driven or drilled piles. HWA can provide criteria for calculating lateral capacities of piles in the final report if this foundation option is selected. 4.2.4 Estimated Settlement Differential settlement can occur between two foundation systems when one system settles more quickly than the other. Because the site is underlain by compressible organi :•ils, we anticipate that settlement of SW 27th Street will continue to occur. Pot- . ly differential settlement could occur between the settling roadway emb. •ment/pave • •nt and a culvert structure not supported on organic material. Cu. - tly, e arch C culverts are supported in/on the organic silt and are most 1' ely settli• t - sa e rate as the surrounding roadway embankment. Howeve tructu es f•. ded on pi I-s • d structures founded on less compressible alluvi. sans will settl• a otice. .le •ifferent rate. As a result, movement across the footp nt oft e ne cu vert(•I coul• cau e transverse cracking to develo• • the p•vem= t.

We anti t ip:to t at the culvert and backfill will weigh slig or; tr an the exis ' g ••it t . ' will 'i•• ace. In our opinion, this pressure incre. - • rel. ivrly rni or ant .•te ial se ement of the structure will depend largely on the . acts 's metros s and , e - ount of subgrade disturbance which occurs during cor.stru The exten• of•isturb ncee subgrade will depend, in part, on whether the structure is constructed in a d. or wet condition. Under ideal conditions, total post-construction settlement o e four-sided box culvert structure due to the increase in load may be less than inch. However, based on the subsurface conditions anticipated and the disturbance expected if construction is performed in the dry, we estimate total settlement may be on the order of 1 inch. If construction is performed in the wet, we anticipate maximum settlements will be on the order of 2 inches. Settlement from construction of the new box culvert will impact the supporting backfill soils around the existing utilities. Evaluations should be performed to verify that the existing pipelines can accommodate the magnitudes of settlement estimated above, which will depend on the method of installation. 98032.doc 8 HWA GEOSCIENCES INC. October 26, 1998 HWA Project No. 98032 Sand boils at the bottom of the excavation or subgrade soils disturbed during construction could result in settlement of the structure. Occurrence of sand boils can be minimized by proper construction dewatering, and/or providing sufficient sheet pile embedment below the bottom of excavation to provide base stability. In the event of sand boils or subgrades disturbed by construction activities, a minimum of the upper 12 inches of disturbed material should be removed and replaced with compacted crushed rock. 4.3 BACKFILL PLACEMENT AND COMPACTION All materials used for backfilling overexcavations of unsuitable soils, and used for the crushed rock working pad should consist of materials meeting the requirements for Crushed Surfacing Base Course, as described in Section 9-03.9(3) of the 19•' ' SD T Standard Specifications for Road, Bridge, and Municipal Constructi• . aterials -.ed to backfill excavations for the culvert should consist of Bank ' r. -1 for Tr:' ch Backfill, as described in Section 9-03.19 of the 1998 WS P • Stan,•. :•:cifi••tions.

During pl.ce - •f tie i itial lifts, the backfill material should not be bulldozed into the excavation or •roppe' dir - y on the structure. Furthermore, heavy vibratory equipment should not be pe •: ted to operate directly over the structure until a minimum of 3 feet of backfill has •: placed. In order to minimize subsequent settlement of the excavation backfill, new pavements, and existing utilities, we recommended that backfill soils be placed in horizontal lifts less than 8 inches in thickness, and compacted to at least 95 percent of maximum dry density, as determined using test method ASTM D 1557 (Modified Proctor). The procedure to achieve proper density of compacted fill depends on the size and type of compaction equipment, the number of passes, thickness of the layer being compacted, and certain soil properties. When access restricts the use of heavy equipment, smaller equipment can be used, but the soil must be placed in thin enough lifts to achieve the required compaction. 98032.doc 9 HWA GEOSCIENCES INC. . October 26, 1998 HWA Project No. 98032 4.4 EXCAVATION AND TEMPORARY SHORING Installation of the proposed culverts will involve open cuts. We anticipate excavations can be accomplished with conventional equipment such as backhoes and trackhoes. Excavations are anticipated to have maximum depths on the order of 20 feet below the existing ground surface for the 30 foot by 10 foot box culvert (Alternative 1) and the 30 foot by 6.7 foot box culvert (Alternative 2). Excavations for the 30 foot by 4.7 foot box culvert (Alternative 2) will require excavations on the order of 17 feet below the pavement surface. Providing the site is dewatered below the depth of the cut, temporary excavations can be sloped at 11/2H:1 V (horizontal:vertical) or flatter. This allowable cut slope inc - ion is applicable to excavations above the water table only. If excavations ext elow the water table, flatter side slopes will be required; the slope angle sh.• . h e monito and adjusted in the field based on local subsurface conditions a.: e con' ac 's m thods. With time and the presence of seepage and/or . i.itatio', th; stability of temp rary unsupported cut slopes can be significantly re i uced.

Shoring is expected o be required where excavations encroach on the existing roadways. For these cases •e recommend using steel sheet piling designed to withstand the lateral earth pres • e and surcharge loading against the shored wall. Design parameters for sheet pile walls are shown on Figure 6. We recommend that the contractor be required to submit a shoring/excavation plan for the review of the project engineer prior to construction. The plan should be required to contain specific measures for temporary support and protection of the existing utilities and structures. 4.5 GROUNDWATER CONTROL/DEWATERING We recommend implementing construction dewatering measures before subgrade excavation begins. Construction dewatering is important because it will be very difficult - 98032.doc 10 HWA GEOSCIENCES INC. ' October 26, 1998 HWA Project No. 98032 to prepare subgrade, evaluate subsurface conditions, and construct structures underwater. Placement of backfill material will also be difficult under submerged conditions. Groundwater seepage into the open excavation will tend to destabilize side slopes and increase lateral loads on temporary shoring systems. In addition, groundwater flow into the excavation can cause sand boils or heaving at the bottom of excavations. Because of these impacts dewatering should be accomplished so that excavating and construction of . the culvert can be completed in the dry. We recommend that temporary excavations be dewatered to maintain the groundwater level at least 2 feet below the base of the excavation. Dewatering should continue until the culvert has been placed and backfilled, and is capable of resisting hydrostatic forces. Recently, a box culvert crossing project was completed for the Olym.i.. ipe Line Company at the nearby intersection of Lind Avenue and SW 2 rd tr:- :. CompLed in September, 1998, the subgrade conditions at the site wer: ery simil. te'f�ie conditions at SW 27th Street and dewatering of the site require. he use of c• i.erdams, sI.mps, and deep wells. Based on the experience at that site an i the ubsu ace o •-jons ol:sery xd in boring BH-1 and BH-2, the followin• genera guide nes = be use• for dewatering estimates. These estimates a .. e tha con ru ion .ccu s in t : •rier summer months and that a storm event does not occur •urin th ur. ion .f t e project. • Sprin.• .ok Cree sh)uld a am ed si co' rd;m ( .g. a combination of sand bags, •color bloc s, ind eel s'eets) and then rer.u'-d ith pumps.

In our opinion, a combination of the above dewatering measures will allow excavations to extend to a depth of approximately 20 feet below the existing ground surface under ideal weather conditions and allow subgrade preparations to be completed in relatively dry conditions. Extended dewatering could result in lowering the water table over a large area which would cause settlement of the underlying alluvial soils. The magnitude of the settlement and its lateral extent would depend on the amount of change in the water level; the length of time the water level was lowered; and the compressibility, thickness, and permeability of the underlying soils. Based on the soil conditions encountered during our site 98032 doc 1 1 HWA GEOSCIENCES INC. October 26, 1998 HWA Project No. 98032 investigation, and the proposed dewatering plan described above, we estimate that the areas that may be impacted by groundwater drawdown could extend about 40 to 50 feet away from dewatered excavations. We estimate maximum settlements of the soil within this zone of influence as the result dewatering operations would be on the order of 1 to 11/2 inches. Settlement will be greatest where groundwater drawdown is at a maximum, and will decrease with increasing distance from the dewatered area; i.e. 20 feet from the well the settlements may be approximately one-third of the above settlements, 50 feet from • the well the settlements are estimated to be negligible. Dewatering within a sheet pile enclosed excavation with sufficient sheet pile embedment acting as a cut-off wall to groundwater flow will result in less groundwater discharge and drawdown over smaller areas. As a result, less settlement of the adjacent soils would be expected. The extent of dewatering-related groundwater drawdown should be . i nitored du •. construction to minimize the potential for settlement damage. ' ior t i onstruc I on, the contractor should determine an appropriate dewatering sc eme and .• t de atering plan to the project engineer for review. 5.0 UNC ' A ; TIE A D IM TATIO►' We have prepared this resort f. . e b the it f R to an• R.

The wetland report has been prepared for the City of Renton's Springbrook Creek flood control and S.W. 27th Street culvert improvements project. The S.W. 27th Street culvert project is located in Section 25, Township 23 North, Range 4 East and Section 30, Township 23 North, Range 5 East. A wetland delineation was conducted by Jones& Stokes Associates on April 8 to 11, 1998 between S.W. 19th Street and 100 feet south of S.W. 27th Street. Jones& Stokes Associates used the U.S. Army Corps of Engineers Wetland Delineation Manual (Environmental Laboratory 1987) and the Washington State Wetland Delineation Manual (Washington Department of Ecology 1997) as summarized in Appendix A. In addition, the report includes by reference previous studies which identified wetlands and waters of the United States associated with Springbrook Creek between the Oakesdale Avenue Bridge and S.W. 19th Street. This report has been prepared for the City of Renton Public Works Department and is intended to be used by the U.S. Army Corps of Engineers (Corps) and City of Renton Planning Department for review and verification of the delineation. Because project designs have not been completed at this time, project impacts and mitigation are not included in this document. This report is a stand-alone document which presents a brief project description and location, results of the wetland delineation, functions and values of the portion of wetlands within the project area, and methods for the delineation. The wetland delineation conducted by Jones & Stokes Associates was based on best professional standards using accepted field methods. Results of the delineation are based on the conditions observed in the field during the time of the delineation. Final verification of jurisdictional wetland boundaries, however, is the responsibility of the Corps and City of Renton. BECK/SPRINGBROOK 1 03/05/99e PROJECT DESCRIPTION AND LOCATION The City of Renton has prepared the East Side Green River Watershed Plan(ESGRWP) and Final Environmental Impact Statement that describes alternatives to implement a surface water management plan that will reduce flood hazards in the watershed (R.W. Beck 1996). One recommendation of the ESGRWP involves channel improvements along Springbrook Creek. These improvements are identified as Alternative SC3, elements 1 and 2. Element 1 proposes to replace tow undersized culverts across S.W. 27th Street. Element 2 consists of channel widening and restoration between S.W. 16th Street and S.W. 23rd Street, concentrating on flood conveyance and wildlife habitat improvements outside of the low flow channel. Emphasis will be placed on the introduction of high flow benches and more extensive plantings up to the ordinary high water mark. This action would be done to reduce flooding, improve the existing flow capacity of Springbrook Creek, and maintain or improve environmental resources associated with Springbrook Creek. The Joint Aquatic Resources Permit Application (JARPA) submitted in March 1999, and in conjunction with this wetland report, is for the specific S.W. 27th Street culvert replacement project. To determine where wetlands occur along the Springbrook Creek corridor, a wetland delineation was conducted within the project site. For the purposes of this delineation, the project site is a 140-foot-wide corridor centered along Springbrook Creek from S.W. 19th Street to 100 feet south of S.W. 27th Street (Figures 1 and 2). In addition, wetlands were delineated along the channelized portion of Rolling Mills Creek from Raymond Avenue to its confluence with Springbrook Creek (Figure 2). Wetlands between S.W. 16th Street and S.W. 19th Street along Springbrook Creek have been previously delineated and described in wetland reports submitted to Renton (Parametrix 1996, U.S. Army Corps of Engineers 1998). SUMMARY OF SITE CONDITIONS Most of the land within the 140-foot-wide Springbrook Creek corridor is undeveloped. Parcels surrounding the project site are developed as industrial complexes or remain as undeveloped areas dominated by grass or shrubs. The site is generally flat with topographic elevations of the areas outside of the main Springbrook Creek channel ranging from approximately 10 to 20 feet above sea level(1988 North American vertical datum [NAND 1988]). (Topographic information used in this report is based on maps prepared by the City of Renton at 0.5-meter intervals and onsite observations.) Upland and wetland areas are located in the undeveloped land outside of the main Springbrook Creek channel. Wetland areas identified in Renton's wetland inventory database are found in the lower lying areas where ponding or high groundwater occurs (Figure 3). Soils along Springbrook Creek in the project area include Puyallup fine sandy loam, Snohomish silt loam, and Woodinville silt loam(U.S. Soil Conservation Service 1973); Snohomish and Woodinville soils are considered hydric soils by the Natural Resources Conservation Service (NRCS) (U.S. Soil Conservation Service 1991) (Figure 4). BECK/SPRINGBROOK 2 03/05/99e Springbrook Creek is generally a trapezoidal-shaped channel with a 5- to 10-foot-wide bench on either side of a low flow channel. The low flow channel banks are generally vertical up to the adjacent bench; the ordinary high water mark can be seen on the banks where vegetation begins growing, rooted in the banks. The bench above the low flow channel varies approximately 2 to 6 feet in elevation above the channel's surface water elevation(as observed in April 1996 and April 1998). The bench was formed as Springbrook Creek has been widened in the past for flood control and channelized into a linear feature (between S.W. 23rd Street and south of S.W. 27th Street). The channel banks slope up to the top of the outer channel at approximately a 2:1 gradient. Vegetation along the bench and the banks above the bench includes reaches of riparian shrubs dominated by Sitka willow and reaches dominated by monotypic stands of reed canarygrass without shrub cover. Springbrook Creek is considered a state shoreline under Renton's Shoreline Management Program, as mean annual flows are greater than 20 cubic feet per second. The east bank of Springbrook Creek from 200 feet north of S.W. 23rd Street to S.W. 30th Street is designated as conservancy environment because of the adjacent wetlands. The west bank from the Oakesdale Avenue Bridge to S.W. 27th Street is designated as urban environment. Between S.W. 19th Street and S.W. 27th Street, the following drainages flow into Springbrook Creek: • Rolling Hills Creek flows into Springbrook Creek via a 48-inch culvert near S.W. 19th Street from the east (this drainage has been designated as Wetland 2 in this report); ■ two unnamed drainages flow into the west bank of Springbrook Creek approximately 800 and 1,100 feet south of S.W. 19th Street via separate culvert connection; and • the S.W. 23rd Street channel flows into Springbrook Creek on its east side at the S.W. 23rd Street gravel access road. RESULTS OF WETLAND DELINEATION Seven wetlands were delineated between S.W. 19th Street and 100 feet south of S.W. 27th Street within the 140-foot-wide corridor. The location and configuration of the wetlands are shown on the map in the back jacket pocket. Vegetation, hydrology, and soils for each wetland are described in the following section. The U.S. Fish and Wildlife Service classification and City of Renton rating are also presented in the following section. Wetland field data sheets are included in Appendix B. A list of plant species mentioned in this report and their indicator status is included in Appendix C. BECK/SPRBJGBROOK 3 03/O3/99e Wetland 1 - Springbrook Creek Wetland 1 is located along the bench above the low flow channel on both banks of Springbrook Creek (Figure 5). The wetland is considered palustrine emergent/scrub-shrub as classified by the U.S. Fish and Wildlife Service. The wetland is considered adjacent to Springbrook Creek as the wetland boundary is contiguous with the creek. The wetland continues along the entire reach of Springbrook Creek within the project area. This wetland is considered a Category 3 wetland based on Chapter 32, Section 32-4-3 of the City of Renton's ordinance because of the channelization which has disturbed wetland soil and vegetation. Vegetation Vegetation in the palustrine scrub-shrub portion of Wetland 1 is dominated by Sitka willow and reed canarygrass. The Sitka willow grows along the bench above the low flow channel and up the relatively steep (2:1 slopes)banks to the upper edge of the broader Springbrook Creek channel. The willows vary in height from approximately 6 to 18 feet tall. Other shrubs that were observed include red-osier dogwood, Douglas' spirea, and Himalayan blackberry. Understory herbaceous vegetation is dominated by reed canarygrass with horsetail and stinging nettles also present. The scrub-shrub portion of the wetland extends south from S.W. 19th Street for approximately 1,500 feet along the west bank, and 1,150 feet along the east bank in a nearly continuous reach. Vegetation in the palustrine emergent portion of Wetland 1 is dominated by reed canarygrass and stinging nettles. Sitka willow and red-osier dogwood are occasionally scattered along the flow channel bench. Other species include occasional horsetail, colonial bentgrass, and sedge. Reed canarygrass continues beyond the wetland onto the uplands along bank slopes. Soils As previously mentioned, soils along Springbrook Creek have been mapped as Puyallup fine sandy loam, Snohomish silt loam, and Woodinville silt loam(U.S. Soil Conservation Service 1973). Snohomish and Woodinville soils are considered hydric soils by the NRCS (U.S. Soil Conservation Service 1991). Because Springbrook Creek's channel profile has been manipulated by straightening the channel and forming a trapezoidal shape(with low flow benches), soils have been disturbed in the wetland. Indicators of hydric soils, whether they are to be considered relict soil characteristics or indicators of current conditions, include low matrix colors with redoximorphic features such as mottles. Matrix colors observed along the wetland include 10YR 3/2, 10YR 3/1, 10YR 4/1, and 10YR 4/2 in silt loam and sandy loam textures. Mottle colors observed were 10YR 3/3, 10YR 3/4, 10YR 3/6, 10YR5/1, and 7.5YR 3/4. Upland areas did include soils with upland soil characteristics with colors of 10YR 3/2 and 4/2 without mottles(e.g., see data plots W1-7A, 12A, 17A, 2B, and 6B). Hydric soil characteristics were also observed in other areas considered upland; i.e., high banks 6 to 10 feet above the surface water of Springbrook Creek(see data plots W1-10A, 8B, and 10B). These upland soils with hydric BECK/SPRBJGBROOK 4 03/05/99e characteristics may be the result of either(1) hydric soil dredged to form the low flow channel was placed on the upper channel banks, or(2)soil colors developed before the creek was channelized and hydric soil conditions existed along Springbrook Creek or surrounding wetlands. Hydrology Wetland hydrology in the form of saturated soils, flooded, or ponded conditions were not observed during the field delineation. Wetland hydrology is assumed to exist in Wetland 1 during the periods when Springbrook Creek flows are great enough to flood the adjacent bench immediately above the low flow channel. The delineated wetland adjacent to the creek includes that portion of the bench which varies from approximately 1 to 4 feet above the surface water elevations observed in the creek during early April 1996 and 1998. Although the bench is above the elevation of April flows,the elevation of the 2-year conveyance event is approximately 4 feet above the surface water elevations observed in April 1996 and 1998. Hydraulic modeling has determined the elevation of the 2-year conveyance event is 8.7 feet (NGVD) at S.W. 19th Street and 10.2 feet at S.W. 27th Street (R.W. Beck 1996). Therefore, it is assumed under normal conditions, the bench above the low flow channel within 4 feet of the early April surface water elevation would flood at least every 2 years. Field evidence which indicated that the bench occurs within the 2-year conveyance event included moist surface soil and the absence of dead and dry vegetation litter that would be swept away during a high flow event. Portions of the bench and banks above the 4-foot elevation were not as moist and muddy, and the dried litter from reed canarygrass was still present. Steep banks and stream reaches where the bench was higher than the estimated 2-year conveyance elevation (approximately 4 feet above the surface water in the creek)were considered uplands. In many places the wetland boundary corresponds to the topographic break between the low bench and the 2:1 slopes grading up to the upper, outer channel (Figure 5). Wetland 2 - Rolling Hills Creek Wetland 2 surrounds a linear, 350-foot-ong channelized portion of Rolling Hills Creek between Raymond Avenue and Springbrook Creek. The upper wetland boundary was delineated on steep banks rising off the channel bottom. This wetland boundary is approximately 1 foot above the ordinary high water mark of the channel as identified by the water lines on the channel's nearly vertical banks and water stains on the Himalayan blackberry hanging down into the channel. The wetland is considered palustrine scrub-shrub because of the predominance of young red alder and Himalayan blackberry growing at the ordinary high water mark and overhanging the channel. A small portion of the channel at the culvert under Raymond Avenue is sparsely vegetated with reed canarygrass and Himalayan blackberry. Soils in the channel bottom were inundated with 6 to 18 inches of water and had a sulfidic smell indicating anaerobic conditions. The channel discharges into Springbrook Creek via a 48-inch culvert. BECK/SPRINGBROOK 5 03/05/99e Based on Chapter 32, Section 4-32-3 of Renton's ordinance, Wetland 2 is considered a Category 3 wetland because wetland vegetation and soil have been disturbed from channelizing Rolling Hills Creek. Wetlands 3A and 3B (Renton Inventory Wetlands W-11 and W-12b) Wetlands 3A and 3B as labeled during the April 1998 field delineation are identified as Wetlands W-11 and W-12b, respectively, in Renton's Wetland Inventory. A small portion of the larger Wetlands W-11 and W-12b was delineated within the 140-foot-wide corridor on the east and west side of Springbrook Creek (Figures 2 and 3). The portions of these wetlands within the 140-foot corridor are classified as palustrine emergent. The wetlands are separated from Springbrook Creek and Wetland 1 by upland berms which parallel both sides of Springbrook Creek. Wetlands 3A(W-11)and 3B(W-12b)are considered Category 2 wetlands based on Renton's rating system because there has been minimal recent disturbance from human activities in these wetlands. Vegetation Wetland vegetation in the portion of these wetlands within the project site is dominated by reed canarygrass. A few scattered willow and red alder also occur along the edges of the wetlands. Soil Soils in these wetlands have been mapped as Snohomish silt loams and are considered a hydric soil by the NRCS. Hydric soil indicators observed during the delineation include low matrix colors (10YR 3/1)with redoximorphic features such as mottles(10YR 3/4) and presence of a sulfidic smell. Soils along the berms between Wetlands 3A and 3B and Wetland 1 were considered uplands because of the soil colors indicating nonhydric soil conditions. Soil colors of 10YR 3/2 without mottles and high chroma soils (10YR 4/3 and 4/4) with mottles of 10YR 4/1 were observed in soils with silt loam textures (see data plots W1-16A and 12B). Hydrology Wetland hydrology indicators were the presence of saturated soils and free water in the soil pit within the upper 12 inches of the soil surface. Saturated soil was not observed within the upper 24 inches in the upland berms separating the wetlands from Wetland 1 along Springbrook Creek. The source of water to the wetland is high groundwater apparently associated with Springbrook Creek. BECK/SPRINCBROOK 6 03/05/99e Wetland 4A (Renton Inventory Wetland W-10S) Wetland 4A as labeled during the April 1998 field delineation is identified as Wetland W-10S in Renton's Wetland Inventory. The area delineated as Wetland 4A within the 140-foot corridor is a small portion of the larger Wetland W-10S on the east side of Springbrook Creek. The portion of Wetland W-10S within the 140-foot corridor is classified as scrub-shrub. The wetland is separated from Springbrook Creek and Wetland 1 by an upland berm which parallels Springbrook Creek. Wetlands 4A(W-10S) is considered a Category 2 wetland based on Renton's rating system because there has been minimal disturbance from human activities in this wetland. Vegetation Vegetation within the portion of the wetland in the 140-foot corridor along Springbrook Creek is dominated by red-osier dogwood, willow, black cottonwood, and reed canarygrass. Vegetation within the upland area between Wetland 4A and Wetland 1 is reed canarygrass. Several large black cottonwood trees occur in the upland area or at the edge of Wetland 4A(W-10S). Soil Soils in this wetland have been mapped as Woodinville silt loam and are considered a hydric soil by the NRCS. Hydric soil indicators observed during the delineation include low matrix colors (10YR 3/2) with very few redoximorphic features such as mottles (10YR 3/4). Other areas of the wetland near the sample field plot show reduced mottle colors of 10YR 5/1 and bright color mottles of 10YR 5/6 in the 10YR 3/2 matrix (see data plot W4-1A). Soils along the berm between Wetlands 4A and Wetland 1 were considered uplands because of the soil colors indicating nonhydric soil conditions. Soil colors of 10YR 3/2 without mottles were observed in the upland berm between the two wetlands. Hydrology Wetland 4A (W-10S) is located on a flat area that is surrounded by the berm along Springbrook Creek and roadbeds which restrict the outlet of water that collects onsite during the rainy season. Although no ponding or saturation was observed during the field delineation, evidence of ponding was observed from sediment deposits within the wetland beyond the 140-foot corridor. Based on the presence of oxidized rhizospheres of living roots within the 140-foot corridor and the flat topography, it is assumed wetland hydrology exists when heavy spring rains could create ponding and/or saturation for long periods during the beginning of the growing season. BECK/SPRINGBROOK 03/05/99e Wetland 5A (Renton Inventory Wetland W-10N) Wetland 5A as labeled during the April 1998 field delineation is identified as Wetland W-10N in Renton's Wetland Inventory. The area delineated as Wetland 5A within the 140-foot corridor is a small portion of the larger Wetland W-10N on the east side of Springbrook Creek. The portion of • Wetland W-10N within the 140-foot corridor is classified as palustrine scrub-shrub. The wetland is separated from Springbrook Creek and Wetland 1 by a narrow upland berm which parallels Springbrook Creek. Wetland 5A(W-10N) is considered a Category 2 wetland based on Renton's rating system because there has been minimal disturbance from human activities in this wetland. Vegetation Vegetation within the portion of the wetland in the 140-foot corridor along Springbrook Creek is dominated by red-osier dogwood, Sitka willow, black twinberry, stinging nettles, and pig-a- back plant. Vegetation within the upland area between Wetland 5A and Wetland 1 is reed canarygrass. Soil Soils in this wetland have been mapped as Woodinville silt loam and are considered a hydric soil by the NRCS. Hydric soil indicators observed during the delineation include low matrix colors (10YR 4/2)with very few redoximorphic features such as mottles (10YR 3/4) at a 9-inch depth. A greater occurrence of mottles was observed at a soil depth of 12 to 16 inches where mottle colors of 10YR 3/4 and 10YR 3/6 were observed in a 10YR 4/1.5 matrix(see data plot Wetland 5A-plot 1A). Soils along the berm between Wetland 5A and Wetland 1 were considered uplands because of the soil colors indicating nonhydric soil conditions. Soil colors of 10YR 3/2 without mottles were observed in the upland berm between the two wetlands. The upland data plot (see Wetland 5A, plot 2A)is located on the berm approximately 3 feet higher in elevation than the wetland and 2 feet above the elevation of the 2-year conveyance event. Therefore, the upland berm is rarely inundated or saturated from flows in Springbrook Creek. Hydrology Wetland 5A (W-10N) is located in a flat area that is surrounded by the berm along Springbrook Creek and roadbeds which restrict the outlet of water that collects onsite during the rainy season. Although no ponding or saturation was observed during the field delineation, evidence of ponding was observed from sediment deposits within the wetland beyond the 140-foot corridor. Based on the site topography it is assumed wetland hydrology exists when heavy spring rains could create ponding and/or saturation for long periods during the beginning of the growing season. BECK/SPRBJGBROOK 03/0399e 8 1 \� Wetland 5B (Renton Inventory Wetland W-16b) Wetland 5B as labeled during the April 1998 field delineation is identified as Wetland W-16b in Renton's Wetland Inventory. The area delineated as Wetland 5B within the 140-foot corridor is a small portion of the larger Wetland W-16b on the west side of Springbrook Creek. The portion of Wetland W-16b within the 140-foot corridor is classified as palustrine emergent. The wetland is separated from Springbrook Creek and Wetland 1 by a narrow upland berm which parallels Springbrook Creek. Wetland 5B (W-16b) is considered a Category 3 wetland based on Renton's rating system because the site has been disturbed by removing native riparian vegetation, which has created a nearly monotypic stand of reed canarygrass in the wetland. Vegetation Vegetation within the portion of the wetland in the 140-foot corridor along Springbrook Creek is dominated by reed canarygrass. Vegetation within the upland area between Wetland 16b and Wetland 1 is reed canarygrass. Soil Soils in this wetland have been mapped as Woodinville silt loam and are considered a hydric soil by the NRCS. Hydric soil indicators observed during the delineation include low matrix colors (10YR 4/1) with redoximorphic features such as mottles (7.5YR 5/8) in the upper 10 inches of the soil. Wetland 5B (W-16b) is separated from Wetland 1 along Springbrook Creek by a berm that is 3.5 feet higher in elevation than Wetland 5B (W-16b) and approximately 6 feet higher than Wetland 1, above the elevation of the 2-year conveyance event. Therefore, the upland berm is rarely inundated or saturated from flows in Springbrook Creek. Hydrology Wetland 5B (W-16b) is located in a flat area that is surrounded by the berm along Springbrook Creek. Indicators of wetland hydrology were saturated soil at a depth of 4 inches with free water collecting at an 8-inch depth. The source of water to the wetland appears to be high groundwater. The groundwater is hydrologically connected to Springbrook Creek as water was observed seeping out of the banks above the surface water of the creek. BECK/SPRINGBROOK 9 03/05/99e OTHER WETLAND AREAS Other wetland areas within the 140-foot corridor include a narrow drainage with steep banks that is connected to Springbrook Creek via a culvert. This wetland is an unnamed drainage that flows into the west bank of Springbrook Creek approximately 1,100 feet south of S.W. 19th Street. The wetland is dominated by reed canarygrass with dense cover of Himalayan blackberry on the banks. The bottom of the drainage is approximately 9.5 feet lower than the surrounding upland area. Hydric soil characteristics in the wetland were the presence of redoximorphic features such as mottles (10YR 4/1) in a low chroma matrix(7.5YR 3/2). Data plots Wetland 1-13B and 14B describe the upland and wetland conditions. This drainage would be considered a Category 3 wetland because of its disturbed condition from the removal of native vegetation and the culverted connection to Springbrook Creek. The S.W. 23rd Street channel flows into Springbrook Creek on its east side at the S.W. 23rd Street gravel access road. The portion of this channel and the surrounding palustrine scrub-shrub wetland within the 140-foot corridor are included in the delineation as part of Wetland 1. Data plots Wetland 1-11A and 12A describe the wetland and upland conditions in this area. Sitka willow is the dominant shrub with an understory of reed canarygrass and stinging nettles. The wetland around the S.W. 23rd Street Channel is considered a Category 2 wetland. Wetlands within a 140-foot corridor along Springbrook Creek between the Oakesdale Avenue Bridge and S.W. 19th Street include the following: • A wetland constructed for mitigation on the Boeing Customer Service Training Center property west of the creek. • The wetland along the bench above the low flow channel on Springbrook Creek's west bank(U.S. Army Corps of Engineers 1998). This wetland edge was designated to occur at an elevation of 10 feet (NGVD) and includes scrub-shrub vegetation as described for Wetland 1 in this report. • Wetlands within the ordinary high water mark on Springbrook Creek's east bank (Parametrix 1996). Because the east bank becomes very steep south of the Oakesdale Avenue Bridge toward S.W. 19th Street, the jurisdictional limit of Springbrook Creek coincides with the ordinary high water mark. Vegetation within the jurisdictional area on the east bank of Springbrook Creek is similar to that previously described in this report. WETLAND FUNCTIONS AND VALUES Wetlands provide a variety of functions, many of which can directly or indirectly benefit society. Functions that are considered beneficial by society represent the values of wetlands. The relative amount of any given function provided by a particular wetland will depend on many factors BECK/SPRINGBROOK 1 O 03/05/99e such as the size of the wetland, topography, geology, hydrology, types and distribution of habitat present, relationship between the wetland and adjacent upland habitats, and surrounding land uses. Wetland functions for those wetlands delineated between S.W. 19th Street and S.W. 27th Street were qualitatively evaluated using a method developed for the Pacific Northwest (Cooke 1996). The rating system uses a low, moderate, or high quality rating based on a variety of physical and biological factors. Commonly assessed functions and values and criteria used to evaluate the wetland functions are listed in Table 1. The primary function of Wetland 1 along Springbrook Creek is flood storage capability which would be rated high. Another function associated with this wetland is the natural biological support along the scrub-shrub portion of the wetland that provides shade along the creek, organic input into the creek from the overhanging vegetation to support foodchains for aquatic organisms, and the available wildlife habitat. Primary species benefiting from the scrub-shrub vegetation are passerine birds and beavers that may be in the area. The natural biological support and habitat functions are rated as moderate. The vegetation growing along Springbrook Creek also provides a moderate level of erosion control protection along the ordinary high water mark of the creek with the shrubs and dense mat of reed canarygrass rooted in the banks. Reed canarygrass also provides a moderate level of sediment trapping when flood events occur outside of the low flow channel. Functions associated with the other wetlands located off of the main Springbrook Creek channel and within the 140-foot corridor include wildlife habitat for passerine birds and small mammals and flood storage capabilities. Water quality improvement is assumed to be low in the surrounding scrub-shrub wetlands because of the sparse cover of herbaceous vegetation and the lack of a "flow-through" wetland where water can enter and exit the wetland. As stated above, the wetlands off of the main channel are surrounded by berms and roadbeds essentially catching rainfall in the depressional area. These wetlands can act as groundwater exchange sites, where groundwater is recharged as surface water collects in the wetland and percolates through the soil into the groundwater. The small area of the 140-foot project site located in the larger wetland represents a relatively small area where associated wetland functions can occur. CITATIONS Cooke, S.S. 1996.

Cross-Section Showing Wetland Adjacent to Springbrook Creek and Relationship to Surface Flows Appendix A Summary of Wetland Delineation Methods Appendix A Summary of the 1987 Corps of Engineers Wetland Delineation and 1997 Washington State Wetland Delineation and Identification Methods INTRODUCTION Wetlands at the site were delineated using the methodology described in the U.S. Army Corps of Engineers Wetlands Delineation Manual and Washington State Wetland Delineation and Identification Method(Environmental Laboratory 1987, Washington Department of Ecology 1997). The 1987 manual is applied by the U.S. Army Corps of Engineers and the 1997 state manual by local jurisdictions. For regulatory purposes, the federal agencies define wetlands as follows: — Those areas that are inundated or saturated by surface or groundwater at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands generally include swamps, marshes, bogs, and similar areas. The methodology for wetland delineation requires examination of three wetland parameters: vegetation, hydrology, and soils. For an area to be considered a wetland, a positive indicator for all three of these parameters must be present. HYDROPHYTIC VEGETATION Hydrophytic plants are those plants adapted to life in water, soil, or on a substrate that at least periodically lacks oxygen. Commonly occurring plant species have been assigned a plant indicator status by the U.S. Fish and Wildlife Service based on their frequency of occurrence in wetlands. Plant indicator status categories are described in Table A-1. For a vegetation community to be considered hydrophytic, 50% or more of the dominant species in that area are typically rated as facultative or wetter. In the case where half of the dominant species are hydrophytic and half are nonhydrophytic(upland), the determination is made based on the total percent areal coverage of each of the two groups. For example, if more than 50% of the total areal coverage is composed of hydrophytic plants, the community is determined to be hydrophytic. BECK/SPRINGBROOK O3/03ro9e A-1 Table A-1. Plant Species Wetland Indicator Categories Estimated Indicator Probability in Category Occurrence Wetland OBL Obligate. Occur almost always under natural conditions in wetlands. >99% FACW Facultative wetland. Usually occur in wetlands,but occasionally found 67-99% in nonwetlands. FAC Facultative. Equally likely to occur in wetlands or nonwetlands. 34-66% FACU Facultative upland. Usually occur in nonwetlands,but occasionally 1-33% found in wetlands. UPL Upland. May occur in wetlands in another region,but occur almost <1% always under natural conditions in nonwetlands in this region(Region 9). Source: Reed 1988. WETLAND HYDROLOGY Areas possessing wetland hydrology are inundated either permanently or periodically, or the soil is saturated to within 1 foot of the surface for at least 5%, and generally greater than or equal to 12.5%, during the growing season. Direct observations of hydrology, including ponding and soil saturation, may be limited during the dry season or may be misleading during the winter rainy season. However, indicators may be present throughout the year which confirm the presence of wetland hydrology during the growing season. Indicators include water-stained leaves, watermarks, drainage patterns, drift lines, visible sediment deposits, and exposed mud. HYDRIC SOILS Hydric(wetland)soils are defined as those soils which are saturated, flooded, or ponded long enough during the growing season to develop anaerobic conditions that favor the growth and regeneration of hydrophytic(wetland)vegetation. Hydric indicators include low soil chroma, mottles, gleying, high organic content, and sulfidic materials: • Chroma is a measure of the intensity of grayness of the soil color. A chroma of 1, occurring with or without mottles, or a chroma of 2, occurring with mottles, is considered to be low and an indicator of hydric soils. BECK/SPRINOBROOK 03/05/S9e A-2 • Mottles are spots or blotches of contrasting color occurring within the soil matrix. • Gleyed soils are predominantly neutral gray in color. • Soils are considered to be organic if at least 18 inches of the upper part of the soil profile contains organic material, or if the soil consists of organic material resting on bedrock. • Sulfidic materials result when mineral soils are waterlogged. Over time, a reducing environment develops in the soil, producing materials that emit a sulfidic odor. Soils at the Springbrook Creek site were sampled with shovels and examined for hydric indicators. Soil pits were dug to a depth of approximately 20 inches to obtain soil profile information. Observed soil characteristics were compared to the U.S. Soil Conservation Service (SCS) descriptions of mapped soils (SCS 1973) to either confirm the mapping or determine if an inclusion is present. Most soils mapped by the SCS include areas of other soils (inclusions) which may compose from 2 to 50% of that unit. WETLAND BOUNDARY DETERMINATION An overall assessment was made of the site. Plots were sampled and evaluated for the three wetland criteria(vegetation, hydrology, and soils). A wetland or upland determination was made for each plot. Sample plot data were recorded on data sheets and are included in Appendix B. Wetland boundaries were determined based on plot determinations and visual observation of site characteristics. Wetlands were delineated in the field and marked on color aerial photographs. Wetlands were marked with pink and black striped flagging affixed to vegetation at a height of 4 to 6 feet at 25-foot intervals. The flagged wetland edge was surveyed by W&H Pacific. Wetlands were delineated by Mark Matthies and Sarah Cassatt, certified by the Seattle Corps Wetland Delineation Certification Program.
