Additionally, the report serves as the certificate of installation of 90% of the plantings. Each monitoring report should be a stand-alone document. In addition to the current monitoring results and general site conditions, each monitoring report should include sufficient information to allow other biologists to perform the monitoring, and for the City to verify the monitoring. This information will ensure accurate continuation of monitoring in the event of staff turnover in the current applicant's biologist's firm or if the applicant chooses to change consulting firms. In addition to the information currently provided in the submitted First Quarterly Monitoring Report, the following information should be included in future reports: 1. Please provide a list of dates and description of maintenance and planting activities. Include information on activities such as weeding, placing mulch, plants replaced (numbers, species, sizes, etc.), etc. 2. Please provide a copy of the planting plan and the site address, vicinity map, and project site map. 3. Please add the City file number LUA14-000480 to the submitted reports. The project appears to be meeting performance standards. The next monitoring report shall be provided in mid-March 2016 for review. Three copies of the second quarterly monitoring report are to be submitted. If you have any questions, please contact Kris Sorensen at 425-430-6593. cc: Leslie Betlach, Parks, Planning and Natural Resources Director File h:\ced\planning\current planning\wetlands\riverview park bridge\q 1 receipt_riverview park bridge_ lual 4-000480.doc ,Ir Northwest -= Environmental Consulting, LLC TECHNICAL MEMORANDUM TO: FROM: DATE: SUBJECT: Todd Black, City of Renton Brad Thiele, Northwest Environmental Consulting December 7, 2015 Monitoring 2015 Quarter 1 3639 Palatine Avenue North Seattle, Washington 98103 (206) 234-2520 PROJECT: Riverview Park Bridge Replacement l\,Iitigation Monitoring INTRODUCTION The Riverview Park Bridge Replacement project included project activities within the critical area buffer of the Cedar River. These activities require mitigation within the buffer to preserve the natural character of the area. The mitigation plan includes planting goals and performance standards that must be met, and calls for five years of monitoring starting in 2015. This memo summarizes the Quarter 1 site visit. SITE VISIT The Quarter 1 site visit was completed by Brad Thiele (Northwest Environmental Consulting) on November 3, 2015. At the time of the site visit, 90% of the plantings had been completed. The foundations for the new bridge were being poured during the site visit. Pictures from the visit are atrached. The mitigation plan specifies that the following be monitored during quarterly site visits: • Signs of grazing by deer or beaver to installed mitigation plants • Signs of plant mortality, other than herbivory, from disease, improper plant selection, exposure to extreme climate conditions, poor plant establishment • Signs of unacceptable reestablishment of non-native species • Signs of vandalism or illegal dumping • Condition of hog fuel mulch, including areas of erosion, depth less than 2 inches, and saturation at surface • Condition of irrigation system that include missing or damaged lines and heads or erosion resulting from leaks or damage OBSERVATIONS The following observations were made during the Quarter 1 site visit: Szgns ofgra,:jng by deer or beaver to installed mitigation plants: At least one of the planted conifer trees had been damaged by rutting. alive and may survive (see Photo 1). Page I of2 This conifer was still ' S{gns of plant mortality, other than herb ivory, Jrom disease, improper plant selection, exposure to extreme climate conditions, or poor plant estahlishment: The plants were recently installed. A few plants appeared stressed but were still alive (see Photo 2). If these plants do not survive the first year, they will be replaced in 2016. The plants may have been stressed due to the recent transplanting, or because of the change in seasons. Many deciduous shrubs had dropped leaves for the year. S {gns of nnacceptable reestablishment of non-native sped es: Two invasive species were noted within the planting areas during the site visit: Himalayan blackberry (Rubus armeniacus) and holly (Ilex aquifoli11m). These species appeared to have been removed and were resprouting (see Photos 3 and 4). Signs of vandalism or illegal dumping: No vandalism was apparent. A small amount of litter was observed along the edges of the planting areas. Some construction debris from past projects was present at the site (see Photos 5 and 7). Condition ofhogjue! mulch, including areas of erosion, depth less than 2 inches, and saturation at surface: Mulch had been spread in the planting areas. Mulched areas were covered by leaflitter, which will add to the effectiveness of the mulch (see Photos 1 through 6). Condition of imgation system that include missing or damaged lines and heads or erosion res11ltingfrom leaks or damage: The irrigation system was installed but was not in use (see Photos 7 and 8). ACTION ITEMS Based on the Quarter 1 site visit, Northwest Environmental Consulting recommends the following: • Remove debris from site. • Remove invasive species from planting areas before spring leafout.

There are no impact to Parks. Separate plans and permits are required for the re installation of this :,~i~f@~ijit~~w~.{j(i~1 Recommendations: I have completed a preliminary review for the above referenced bridge replacement proposal at Parcel Number 1623059033. The following comments are based on the application submittal made to the City of Renton by the applicant. EXISTING CONDITIONS WATER: The site is located in the City of Renton water service area. SEWER: The site is located in the city of Renton sewer service area. STORM: There is storm drainage in portions of Maple Valley Highway. STREET: Maple Valley Highway (SR 169) fronting the site is a Principal Arterial street. CODE REQUIREMENTS Water 1. The project proposes the temporary removal of the water service line that is currently hung underneath the bridge. Water permits are required for the cut and cap of the water service line. Sanitary Sewer 1. The site is served by City of Renton sewer service. The project proposes the temporary removal of the sewer line that is currently hung underneath the bridge. A portable toilet is proposed to be available to park users during bridge construction. The cut and cap of the sewer line must be done. The sewer line must be protected from damage, from things getting into it, and things getting out of it. Stormwater 1. A drainage report (TIR) based on the 2009 King County Surface Water Drainage Manual and City Amendments is required to be provided with the Utility Construction permit. All stormwater requirements will be based on the review of the drainage report (TIR). 2. The current surface water system development fee is $0.491 per square feet of new impervious surface with a minimum amount of 1,228.00. Transportation 1. The project involves the demolition of an existing bridge and the construction of a replacement bridge. This work will involve a building permit and as per RMC 4 6 060, may trigger frontage improvements. However, since this is a city and state funded project, frontage improvements may not be applicable. 2. There is a potential safety concern regarding the horizontal ropes proposed under the aluminum pipe handrail on the bridge side. It may be a concern for children climbing on the horizontal ropes. One alternative is to consider vertical ropes instead of the horizontal ropes. If the applicant decides to install horizontal bars on the bridge, it is recommended the City's Risk Manager review the design. 3. Will the bridge be designed for H20 loading? 4. Traffic Impact Fees -The proposed bridge replacement project does not generate additional new trips. Therefore traffic impact fee is not applicable on this project. General Comments 1. All construction or service utility permits for drainage and street improvements will require separate plan submittals. All utility plans shall conform to the Renton Drafting Standards. Plans shall be prepared by a licensed Civil Engineer. Ran: July 15, 2015 Page 1 of 2 ADVISORY NOTES TO APPLICANT LUA 14-000480 Version 1 I May 10, 2014 2. When utility plans are complete, please submit three (3) copies of the drawings, two (2) copies of the drainage report, permit a lication, an itemized cost of construction estimate, and a lication fee at the counter on the sixth floor.

First year monitoring shall be performed quarterly. Results for quarters 1 thru 3 shall be submitted to the City as a short report or memo. Fourth quarter monitoring shall include year 1 monitoring results. Compliance monitoring provides a means for tracking plant survival, cover of installed plants and up to 20 percent of any stratum composed of desirable native volunteers, health and growth, herb ivory, presence of weeds, trash and vandalism. Monitoring methodology includes a variety of ecological techniques. Standard techniques such as transect lines and sample plots may be used. Monitoring includes tracking mortality, establishing photo points and other methods deemed necessary to adequately document development of mitigation areas over the monitoring period. PART lA-MITIGATION APPROACH INSTALLATION Provide mitigation for 19,900 SF {0.5 AC). PART 18 -GOALS AND OBJECTIVES INSTALLATION 1. Enhance 19,900 SF of planting area by clearing existing invasive species {Himalayan Blackberry, Japanese Knotweed, and Reed Canarygrass) and replanting with native trees and shrub species to improve plant diversity and habitat functions. PART lC -PERFORMANCE STANDARDS Performance standards (Table 2) have been established that correspond to the stated mitigation goals and objectives. These standards are the primary factors that shall be used to measure the success of the mitigation areas. It is important to evaluate the development of the mitigation plan over the entire monitoring period when determining whether all standards have been met. While specific performance standards provide important benchmarks and shall help to direct maintenance and contingency efforts, the success of mitigation must be measured against the goals and objectives of the overall mitigation plan. By monitoring the project and comparing monitoring results to performance standards, a determination can be made for the need to implement maintenance efforts or the contingency plan (below). HABITAT MONITORING -RIVERVIEW PARK PAGE 3 OF 4 PART 3-LONG TERM VEGETATION MANAGEMENT The mitigation plan (Parts 1-3) identifies the required actions to be implemented by the City to ensure the establishment of the mitigation areas.

Location: Prior to commencement of planting operations, stake tree locations and stake outer limits of plant beds. The intent is to provide an even coverage of shrub and groundcover plantings throughout the plant bed, working around, and accommodating, existing plant material to remain. Plant spacing, or range of dimensions for plant spacing, is a recommendation but final spacing may be adjusted to accommodate location and spread of existing vegetation. Plant massing will likely be increased in areas where there has been more significant removal of invasive plant material. Obtain approval of Owner's Representative prior to planting, and adjust plantings as directed. D. Excavation of Plant Pits: Completely rip soils and scarify sides and bottom of all plant pits to dimensions shown on the plans. Remove any impervious or otherwise unsuitable soils or material to a minimum of 12" below bottom of plant pit and minimum 12" beyond sides of plant pit around each tree and shrub. 1. Tree and Shrub pits are to be excavated 6" deeper and 6" wider (all sides) than the root ball or container size. 2. Groundcover pits are to be excavated full depth of container and 3" wider (all sides) than the container size. E. Planting Soil Backfill: For trees and shrubs place minimum 6" depth of a blend of 50% topsoil, 50% native soil in bottom of plant pit and compact. Place plant material as noted below. Backfill with a well blended 50/50 mix and proceed as noted below. F. Placement of Plants (Trees, shrubs, and groundcover): Place at normal planting season, unless otherwise approved. Orient as directed for best appearance. Set in center of pits, on scarified site soil backfill. Set plantings to bear same relationship with finish grade after settlement as they bore to natural grade. Hold firmly in position while backfill mixture is being placed. Break down any smooth walls of the plant pit during this backfill process. Place backfill carefully, avoiding root damage and filling all voids. Compact fill by jetting to avoid air pockets. Allow to soak away and continue adding more backfill as required. Add fertilizer tablets, as specified below, near top of root ball during backfill. 1. For container stock: Cut 2 sides with approved type cutter, taking care to avoid any root damage. 2. For balled stock: Cut string and remove fasteners. Remove burlap. 3. For wire baskets: Cut wire and remove wire basket. G. Hog Fuel: Spread hog fuel throughout plant bed area, from limit of existing bed at lawn area to limit of invasive plant removal, as shown on the plans. Depth of hog fuel will range between 2" and 5", with an average calculated depth (for purposes of bidding) of 3W' throughout the plant bed area. Hog fuel shall be spread to a 2" depth in the vicinity of the crown of new plant material and up to 5" depth in areas where invasive plant material removal has left open ground. Depth of hog fuel at irrigation laterals shall be 5", per Section 328400. Adjust placement and depth of hog fuel as directed by Owner's Representative. 3.02 HYDROSEEDING A.

As discussed, the City noted difficulty in placing the trees back into the river due to various constraints. We concur with the City's revised mitigation proposal as acceptable substitute mitigation for this project. We would appreciate copies of the "as-built" planting plans and the annual monitoring reports when they are submitted to the City. Please let me know if you have any questions.

The purpose of the meeting was to discuss and identify an alternative mitigation opportunity to placing Large Woody Debris (LWD) in the river (as previously agreed to) in response to three trees that were removed on the right (north) bank of the river immediately downstream of the existing bridge structure. As part of the prior approval process to remove the three trees, the City coordinated with the Tribe and WDFW and agreed to replant trees at a 3:1 ratio in the same location. The City also agreed to retain the tree trunks to be installed as large woody debris the following year (2015) as part of the new bridge installation process. The contractor however cut the trunks in 8'-15' lengths as part of the tree removal process compromising the opportunity to install LWD at the bridge location -the focus of discussion for alternative mitigation options. The City will continue to replace the three trees at a 3:1 ratio at the same location. Background Renton acquired the bridge and property in 1979. The original bridge structure was estimated to have been constructed in the 1960's and was composed of treated timber pilings set mid- stream and at the edges of the river; the bridge was all-wood construction. In 1995 the City installed a steel girder, wood handrails with wire mesh, and interpretive sign age as part of the park construction and future connection to the Cedar River Trail. Structural repairs were completed in 2005 and included replacing the treated wood decking with precast concrete panels and replacing the timber abutment pilings with concrete abutments; the 18 in-stream creosote treated pilings remained in place. Structural repairs were again completed in 2010 and 2011 after major flood events. Also in 2011, PND Engineers, Inc. was retained to provide a structural assessment of the bridge. Their review found that the structural assembly was compromised due to the inadequate lateral support in the timber piles; the bridge was classified in "poor condition." Renton City Hall , 1055 South Grady Way • Renton, Washington 98057 • rentonwa.gov Karen Walter, Watersheds and Land Use Team Leader Muckleshoot Indian Tribe Fisheries Division Habitat Program October 27, 2014 Page 2 of 3 Renton reviewed several options to repair or replace the bridge. Since the in-stream timber pilings were the weakest link, and logs and other debris coming downstream got caught on the piles, the City determined the best course of action was to replace the bridge with a new single span bridge. An initial budget of $1.1 million was developed to replace the bridge. As full funding was not available through the City's budgeting process, the City sought outside funding assistance and applied for two $500,000 grants in 2012 [State Washington Wildlife and Recreation Program (WWRP) and Federal Land and Water Conservation Fund (LWCF)]. The City was unsuccessful in the two grant requests and then sought legislative funding and secured a $1,067,000 grant from the Department of Commerce in 2013 with a Renton commitment of $100,000. PND Engineers was retained to provide bridge demolition and design plans, habitat planting plans, and permitting applications and environmental support materials. Due to the tight timeframe for construction within the fish windows and as per the Department of Commerce grant requirements, it was determined that demolition would occur in 2014 and the new bridge installation, habitat planting, and interpretive signage installation would occur in 2015. Bridge Demolition To date, the bridge has been demolished. During demolition three Big Leaf Maple trees were identified to be removed in order for the crane operator to safely operate the equipment in the bridge removal process. Coordination with the Tribe and WDFW ensued and the City agreed to replant the trees at a 3:1 ratio in the same location. The City also agreed to retain the tree trunks to be installed as large woody debris the following year (2015) as part of the bridge installation process. During the tree removal process the contractor cut the trunks in 8' -15' lengths compromising the opportunity to install LWD at the bridge location. The City looked into alternative anchoring methods to securely locate the 8'-15' lengths of wood in the river at the Riverview Park location. Ultimately the short lengths of wood and the limited access to the river (more trees would be required to be removed for access to install any wood into the river), potential permit requirements associated with the anchoring methods, Department of Natural Resources Easement requirements, and grant funding time line led the City to discuss alternative solutions. Alternative Solutions The City, Tribe, and WDFW discussed four additional solutions to include the following: • Estimating the value of designing and installing LWD at Riverview Park and placing the value of that work into an account to go toward a future designed habitat enhancement project along the left bank of the Cedar River at Jones Park. • Karen Walter, Watersheds and Land Use Team Leader Muckleshoot Indian Tribe Fisheries Division Habitat Program October 27, 2014 Page 3 of 3 • • Estimating the value of designing and installing LWD at Riverview Park and placing the value of that work into one of the King County habitat sites along the Cedar River or adding onto one of the King County habitat sites nearing construction. • Estimating the value of designing and installing LWD at Riverview Park and placing the value of that work into habitat work to be completed behind the Maplewood Golf Course at the Elliot Levee, or adding onto projects at this location. • Completing a five year habitat monitoring program for the habitat enhancement the City is voluntarily including as part of the bridge replacement project. It was noted that in support of the five year habitat monitoring, the City has a 3-year partnership agreement with the Friends of the Cedar River Watershed and the King Conservation District for knotweed control from 1-405 east to Ron Regis Park which also includes knotweed control at Riverview Park. Final Solution The City, Tribe, and WDFW agreed that the City will monitor the habitat planting for five years and warranty the habitat enhancement for an 80% survival rate for the five-year period to also include plant material replacement and invasive species control. The nearly one-half acre habitat enhancement area is primarily on the top edge of th.e left (south) bank of the Cedar River and in the immediate vicinity of the bridge construction, from the top of bank to the river's edge, and extending approximately 30 feet from the bridge edges. The three Maple trees will continue to be replaced using the 3: 1 replacement ratio. Attached are the 5-year Habitat Monitoring Program specifications and the planting plans for the native habitat planting. The City wants to thank you for taking the time to meet and discuss alternative mitigation solutions and finding a solution so the new clear span bridge can be installed within the 2015 "fish window."

During project bidding, the contractors indicated that it was not feasible to demolish the existing pedestrian bridge without the removal of trees, as indicated in the original Shoreline Exemption. The intended purpose of the subject addendum is to disclose the potential for removal of up to three trees related to bridge demolition. The three trees that could be removed as a part of bridge demolition include three Big Leaf Maples, one 14 inches in diameter, one less than 4 inches in diameter and one multi-trunk with three trunks; 16 inches, 12 inches, and 10 inches in diameter. With the Addendum documentation, the applicant has provided a tree removal exhibit, an updated planting plan, and an Addendum to the Biological Evaluation and Stream Report submitted with the original application (attached). The Addendum to the Biological Evaluation and Stream Report was prepared by Hart Crowser dated June 17, 2014. The report provides an assessment on no net loss of ecological functions and values focusing on the removal ofthe three identified trees. The following areas were reviewed; bank stabilization, large woody debris (LWD), shade, leaf litter and insect fall. The report concludes that the overall removal of two mature trees (trees over 4 inches in diameter) and one smaller tree would represent a temporal loss of some ecological functions within the riparian zone of the Cedar River. However, the amended study indicates that the project conservation measures and new proposed mitigation actions would be sufficient to offset this temporal loss. These actions area as follows: Conservation Measures Addendum to Riverview Replace t Project Shoreline Exemption Page 2 of 2 June 23, 2014 • Potential adverse effects of project actions on salmon will be avoided or minimized through the adherence of agency-approved work windows when few out migrating juvenile salmon and adult spawning salmon are present in the action area (July 1- August 31). • The proposed new bridge replacement will be constructed with a slightly smaller overwater footprint as the old bridge. No increase in overwater coverage will occur. • No construction activities or machinery will occur in the water. All staging will occur in either the existing parking lot or the developed park on either side of the river. Mitigation Actions • Native tree species will be planted in the area of tree removal at a ratio of 3:1. This ratio would apply to individual trees that are removed. • The larger tree trunks (10-inch diameter or greater) that are removed will be anchored as large woody debris within the steam channel. • Areas of tree removal would be periodically inspected for bank instability and erosion control measures implemented if it is determined that tree removal has caused compromised stream banks that may adversely affect the steam channel. Finally, the provided amended study states that the removal of creosote-treated piles from near bank areas, mid-channel areas, and the placement of large woody debris in the stream channel would provide long-term improvements in habitat quality and that these habitat improvements would more than offset the immediate or temporal decreases in ecological functions causes by the removal of three trees. Pursuant to WAC 173-27-100 shoreline permits revisions are required whenever the applicant proposes substantive changes to the design, terms, or conditions of a project from that which is approved in the permit. Changes are substantive if they materially alter the project in a manner that relates to its conformance to the terms and conditions of the permit, the master program and/or the policies and provisions of chapter 90.58 RCW. Changes which are not substantive in effect do not require approval of a revision. The proposed change to the project scope to remove two mature trees and one smaller tree would not be considered a substantive change to the original shoreline exemption as such it has been determined that an revision to the shoreline permit is not warranted. Please note this memorandum is provided to document the change and the determination of a non-substantive change to the Shoreline Exemption for the Riverview Bridge Replacement Project.

MEMORANDUM DATE: TO: FROM: RE: CC: June 17, 2014 Laura Gurley, PND Engineers Jim Starkes, Fisheries Biologist Biological Evaluation and Stream Report Addendum -Riverview Park Bridge Replacement Project 12132-29 Jon Houghton, Senior Principal, Hart Crowser Introduction This memorandum serves as an addendum to the Draft Biological Evaluation and Draft Stream Report, dated March 2014, for the Riverview Park Bridge Replacement Project in Renton, Washington (Hart Crowser 2014a, b). This addendum evaluates a modification of the project description to determine whether the original conclusions of no net loss of ecological functions are still valid. The original project description proposed to conduct the bridge replacement without the removal of any mature trees in the project area. The revised project description calls for the removal of three trees of the following size (diameter at breast height [dbh]): • One multiple-trunk big leaf maple with trunks of 16, 12 and 10-inch dbh; • One single-trunk big leaf maple of 14-inch dbh; and • One single-trunk big leaf maple under 4-inch dbh. All of the trees are within 50 feet of the existing bridge on the north side of the river (right bank); contractors have reported that bridge demolition, removal, staging, and construction of the new bridge may not be possible without the removal of these trees. To compensate for their loss if they are removed, the City proposes to anchor the four tree trunks of 10-inches dbh or wider as large woody debris (LWD) in the stream channel. The City also proposes to replant the area of tree removal at a 3-to-1 ratio of 2-gallon-sized trees. Acceptable replacement species are big leaf maple, cottonwood, or native conifer species. Because the presence of the trees interferes with bridge replacement work, trees will be removed before the existing bridge is removed and replanting will not occur until the new bridge has been constructed. The existing bridge is scheduled for removal during the summer of 2014 and the 120 Third Avenue Sovth, Suite 110 Edmonds, Washington 98020~8411 Fax 425. 778.9417 Toi 425. 775.4682 -.. PND Engineers June 17, 2014 12132-29 Page 2 new bridge will be constructed during the summer 2015. The time between tree removal and replantation will be approximately one year. This construction schedule is necessary because both removal of the existing bridge and construction of the new bridge cannot be completed within a single agency-approved work window. Assessment of No Net Loss Ecological Functions The loss of the two mature big leaf maples and the smaller tree represents a loss of the following riparian functions: • Bank stabilization through root penetration and bank strengthening; • LWD supply; • Shade and moderation of water temperatures; and • Leaf litter and insect fall for the retention and recycling of nutrients. Bank Stabilization. The large root systems of mature trees usually contribute substantially to the strengthening of stream banks. In this case, the steep banks in the project area have been armored to protect adjacent park uplands to the south and roads to the north, so it is not known to what extent native vegetation contributes to bank stabilization. It is also unlikely that planted trees would recover this function for many years, since the trees proposed for removal are mature, and in one case, multi- trunked. LWD. LWD increases habitat complexity and contributes to building additional habitat features within the stream channel. Anchoring the larger of the removed trees into the stream channel will provide this important ecological function. Because of the existing steep slope of the river banks and the narrow riparian zone, there are also few candidate mature trees that can be recruited to the channel in the project area. There will be a temporal loss in ecological function given the time period between tree removal and stream channel placement. Shade. Proposed removal of the mature trees represents a minor temporal decrease of this function within the riparian zone since most of the existing trees that remain are young and replacement trees will be saplings. However, the amount of shade produced by the existing trees has been naturally limited on the north bank due to the sun's position and movement in the sky. Most of the shade falls onto the adjacent parking area on the north side of the river. Leaf Litter and Insect Fall. Mature big leaf maples provide substantially to this function since they have large leaves and tend to grow multiple trunks. The loss of this function will be offset by replacing -.. PND Engineers June 17, 2014 12132-29 Page 3 removed trees with planted trees at a 3-to-1 ratio. There will be a temporal loss in ecological function given the time period between removal and revegetation. Analysis The revised project description proposes to replace trees that are removed with native tree species, but there will be a temporal loss of function between bridge removal and construction. Regulators often require compensation for such temporal losses in ecological functions by increasing the size of mitigation needed, usually referred to as a mitigation ratio. Washington Department of Ecology (Ecology) has no identified guidance for riparian areas, but the proposed project will provide a ratio of 3:1. Ecology guidance also indicates that temporal losses increase with time and with them, the temporal loss factors applied as mitigation. The guidance states that the above mitigation ratios are appropriate for projects completed within one year of impacts (Ecology 2012). The time period between tree removal and revegetation/LWD placement will be approximately one year. Existing guidance suggests that the proposed delay between tree removal and conservation/ mitigation actions are sufficient if the project holds to this schedule. Available guidance suggests that the 3:1 planting ratio is sufficient to offset removal of mature trees. Even with the 3:1 planting ratio, the shading function will be lower; but, as reported, this function is somewhat diminished, given the position of the impact in relation to the stream channel. Any loss of this function also becomes more prominent and relevant with larger scale riparian removals, particularly with the size of the stream channel in the project area. Given the small number of trees proposed for removal, the level of temperature moderation is likely to be negligible or unmeasurable. However, it should be noted that the removal of riparian vegetation and the steepening of stream banks that prevent a mature riparian canopy from extending over the channel has historically contributed to temperature warming in the lower river (Kerwin 2001). In this sense, replacement trees should be placed in areas where they can grow to a mature size, since this is a limiting habitat factor in the project area. Placement of the larger removed trees in the stream channel will provide similar ecological functions of naturally downed trees within the riparian zone. For LWD placement, all but the narrowest portion of the tree trunk should be used. LWD will have to be securely anchored near the toe of the bank or on the gravel bar to prevent wood from being washed downstream from high flows or contact with other pieces of wood. The proposed pieces, properly and permanently anchored, will increase habitat complexity and contribute to the building of new stream habitat features such as backwater refuge areas, gravel bar development, and scour pools. This is particularly important in this reach of river where -.. PND Engineers June 17, 2014 12132-29 Page 4 LWD recruitment has been diminished because of steepened/armored banks, a diminished stream meander zone, and a narrowed riparian buffer. Conclusions Overall, the removal of two mature trees and one smaller tree will represent a temporal loss of some ecological function within the riparian zone of the Cedar River, but project conservation measures and mitigation actions will sufficiently offset this loss. These actions are outlined below. Conservation Measures • Potential adverse effects of project actions on salmon will be avoided or minimized through the adherence of agency-approved work windows when few outmigrating juvenile salmon and adult spawning salmon are present in the action area (July 1-August 31). • The proposed new bridge replacement will be constructed with a slightly smaller overwater footprint as the old bridge. No increase in overwater coverage will occur. • No construction activities or machinery will occur in the water. All staging will occur in either the existing parking lot or the developed park on either side of the river. • All creosote treated piles below ordinary high water will be removed and properly disposed of at an approved upland disposal facility. Replacement steel piles will be driven in entirely upland areas. Mitigation Actions • Native tree species will be planted in the area of tree removal at ratio of 3:1. This ratio will apply to individual trees that are removed. • The larger tree trunks (10-inch dbh or greater) that are removed will be anchored as large woody debris within the stream channel. • Areas of tree removal will be periodically inspected for bank instability and erosion control measures implemented if it is determined that tree removal has caused compromised stream banks that may adversely affect the stream channel. The removal of creosote-treated piles from near bank areas, mid-channel areas, and the placement of large woody debris in the stream channel will provide long-term improvements in habitat quality. The temporal lag in tree removal and the implementation of habitat improvements is necessary to protect multiple stocks of both juvenile and adult salmon that use the reach as a migratory corridor, rearing areas, and spawning grounds (Hart Crowser 2014a, b). These habitat improvements will more than -.. PND Engineers June 17, 2014 12132-29 Page 5 offset the immediate or temporal decreases in ecological functions caused by the removal of three trees.

Three trees may be removed from the bank on the north side of the bridge to accommodate safe operation of construction equipment. These trees are specifically: 1. Big Leaf Maple with three ttunks (16", 12" and 10" diameter); 2. Big Leaf Maple with single trunk (14" diameter); 3. Big Leaf Maple with single trunk (under 4" diameter, thus not shown on survey). Those trunks greater than 10-inch diameter dbh will be retained for installation in the Cedar River as large woody debris habitat. Each trunk shall be cut such that the trunk is kept intact between the closest cut to the ground and the point where the diameter of the trunk naturally tapers to 6- inch diameter. These trees will be stockpiled on site for installation in the river during the in-water work "vindow of summer 2015. Each tree will replaced with three trees of at least 2-gallon size (total of nine replacement trees). Acceptable replacement species are big leaf 1naplc, cottonwood, or native conifer species. Replacement trees will be located as shown on the attached 60°/,, Design Planting Plans (MacLeod Reckard) 1\s required by the City, an addendum to the Biological Evaluation and Stream Study Reports has been prepared by Hart Crowser 0 une, 2014) evaluating the net effects of the tree removal, replacement and L\v'D placement.

Assessment of No Net Loss Ecological Functions The loss of the two mature big leaf maples and the smaller tree represents a loss of the following riparian functions: • Bank stabilization through root penetration and bank strengthening; • LWD supply; • Shade and moderation of water temperatures; and • Leaf litter and insect fall for the retention and recycling of nutrients. Bank Stabilization. The large root systems of mature trees usually contribute substantially to the strengthening of stream banks. In this case, the steep banks in the project area have been armored to protect adjacent park uplands to the south and roads to the north, so it is not known to what extent native vegetation contributes to bank stabilization. It is also unlikely that planted trees would recover this function for many years, since the trees proposed for removal are mature, and in one case, multi- trunked. LWO. LWD increases habitat complexity and contributes to building additional habitat features within the stream channel. Anchoring the larger of the removed trees into the stream channel will provide this important ecological function. Because of the existing steep slope of the river banks and the narrow riparian zone, there are also few candidate mature trees that can be recruited to the channel in the project area. There will be a temporal loss in ecological function given the time period between tree removal and stream channel placement. Shade. Proposed removal of the mature trees represents a minor temporal decrease of this function within the riparian zone since most of the existing trees that remain are young and replacement trees will be saplings. However, the amount of shade produced by the existing trees has been naturally limited on the north bank due to the sun's position and movement in the sky. Most of the shade falls onto the adjacent parking area on the north side of the river. Leaf Litter and Insect Fall. Mature big leaf maples provide substantially to this function since they have large leaves and tend to grow multiple trunks. The loss of this function will be offset by replacing .. .. .. PND Engineers June 17, 2014 12132-29 Page 3 removed trees with planted trees at a 3-to-1 ratio. There will be a temporal loss in ecological function given the time period between removal and revegetation. Analysis The revised project description proposes to replace trees that are removed with native tree species, but there will be a temporal loss of function between bridge removal and construction. Regulators often require compensation for such temporal losses in ecological functions by increasing the size of mitigation needed, usually referred to as a mitigation ratio. Washington Department of Ecology (Ecology) has no identified guidance for riparian areas, but the proposed project will provide a ratio of 3:1. Ecology guidance also indicates that temporal losses increase with time and with them, the temporal loss factors applied as mitigation. The guidance states that the above mitigation ratios are appropriate for projects completed within one year of impacts (Ecology 2012). The time period between tree removal and revegetation/LWD placement will be approximately one year. Existing guidance suggests that the proposed delay between tree removal and conservation/ mitigation actions are sufficient if the project holds to this schedule. Available guidance suggests that the 3:1 planting ratio is sufficient to offset removal of mature trees. Even with the 3:1 planting ratio, the shading function will be lower; but, as reported, this function is somewhat diminished, given the position ofthe impact in relation to the stream channel. Any loss of this function also becomes more prominent and relevant with larger scale riparian removals, particularly with the size of the stream channel in the project area. Given the small number of trees proposed for removal, the level of temperature moderation is likely to be negligible or unmeasurable. However, it should be noted that the removal of riparian vegetation and the steepening of stream banks that prevent a mature riparian canopy from extending over the channel has historically contributed to temperature warming in the lower river (Kerwin 2001). In this sense, replacement trees should be placed in areas where they can grow to a mature size, since this is a limiting habitat factor in the project area. Placement of the larger removed trees in the stream channel will provide similar ecological functions of naturally downed trees within the riparian zone. For LWD placement, all but the narrowest portion of the tree trunk should be used. LWD will have to be securely anchored near the toe of the bank or on the gravel bar to prevent wood from being washed downstream from high flows or contact with other pieces of wood. The proposed pieces, properly and permanently anchored, will increase habitat complexity and contribute to the building of new stream habitat features such as backwater refuge areas, gravel bar development, and scour pools. This is particularly important in this reach of river where -.. PND Engineers June 17, 2014 12132-29 Page4 LWD recruitment has been diminished because of steepened/armored banks, a diminished stream meander zone, and a narrowed riparian buffer. Conclusions Overall, the removal of two mature trees and one smaller tree will represent a temporal loss of some ecological function within the riparian zone of the Cedar River, but project conservation measures and mitigation actions will sufficiently offset this loss. These actions are outlined below. Conservation Measures • Potential adverse effects of project actions on salmon will be avoided or minimized through the adherence of agency-approved work windows when few outmigrating juvenile salmon and adult spawning salmon are present in the action area (July 1-August 31). • The proposed new bridge replacement will be constructed with a slightly smaller overwater footprint as the old bridge. No increase in overwater coverage will occur. • No construction activities or machinery will occur in the water. All staging will occur in either the existing parking lot or the developed park on either side of the river. • All creosote treated piles below ordinary high water will be removed and properly disposed of at an approved upland disposal facility. Replacement steel piles will be driven in entirely upland areas. Mitigation Actions • Native tree species will be planted in the area of tree removal at ratio of 3:1. This ratio will apply to individual trees that are removed. • The larger tree trunks (10-inch dbh or greater) that are removed will be anchored as large woody debris within the stream channel. • Areas of tree removal will be periodically inspected for bank instability and erosion control measures implemented if it is determined that tree removal has caused compromised stream banks that may adversely affect the stream channel. The removal of creosote-treated piles from near bank areas, mid-channel areas, and the placement of large woody debris in the stream channel will provide long-term improvements in habitat quality. The temporal lag in tree removal and the implementation of habitat improvements is necessary to protect multiple stocks of both juvenile and adult salmon that use the reach as a migratory corridor, rearing areas, and spawning grounds (Hart Crowser 2014a, b). These habitat improvements will more than .. .. PND Engineers June 17, 2014 12132-29 Page 5 offset the immediate or temporal decreases in ecological functions caused by the removal of three trees.

We have determined that a DA permit is not required for your proposed work as described in your application and drawings. Under Section 10 of the Rivers and Harbors Act of 1899, a Section JO DA pe,mit is normally required for work or structures in or affecting navigable waters of the U.S. Because the reach of the Cedar River where the work would occur is not a navigable water, a Section 10 DA permit is not required. Under Section 404 of the Clean Water Act, a DA permit is normally required for the discharge of dredged or fill material (e.g., fill, excavation, oi mechanized land clearing) into waters of the U.S., including wetlands and navigable waters of the U.S. For more information, see the enclosed Clean Water Act Extracts and Definitions. The Cedar River is a water of the U.S. However, because removing and replacing the pedestrian bridge does not involve a discharge of dredged or fill material, a Section 404 DA permit is not required. While a DA permit is not required, local, state, and other federal requirements may still apply. For assistance in determining other permit requirements for the proposed project, we recommend you contact the Washington State Office of Regulatory Assistance via the internet at www.ora.wa.gov. .. .... -2- A copy of this letter without enclosures will be furnished to Ms. Laura Gurley, PND Engineers, Incorporated, 1736 Fourth Avenue South, Suite A, Seattle, Washington 98134.

We have been working with the Parks Department for some time on this project and were pleased to learn that the City is propose a grated, full spanning bridge as the bridge replacement design. Previously, we have discussed the need for invasive control, particularly Japanese knotweed, along the river in the park, as well as, reestablishing native conifers along the Cedar River banks. It appears that there will be some riparian enhancement as part of this project; however, the planting details and a proposed monitoring plan is lacking from the materials we have reviewed to date. We would like copies of both documents for our review.

The existing bridge provides pedestrian connections from the parking lot to Riverview park located on the south side of the Cedar River. The bridge crosses the Cedar River, in Reach C, where the north bank is designated Shoreline High Intensity and the south bank is designated Urban Conservancy. The park is zoned Resource Conservation (RC) and is 11.53 acres in size. The project would impact 6,000 SF for the bridge replacement and 19,873 SF for shoreline vegetation plantings and enhancement. The replacement bridge would be constructed of aluminum providing a clear span of the Cedar River. This would result in the removal of 18 piles currently below the Ordinary High Water Mark (OHWM). The project is located in the 100 year flood plain and floodway of the Cedar River, Aquifer Protection Zone 1, Landslide hazard area, protected slopes, and a seismic hazard area. The applicant submitted a geotechnical report, Biological Assessment and a Stream Study with the land use application. These studies conclude that the project would result in "no net loss of ecological functions and values". No trees are proposed to be removed as a result of the subject project. The subject project is compliant with the development standards and use standards of the Shoreline Master Program, specifically sub-sections; RMC 4-3-090D.4.d.iv Recreation, E.8.a when recreation is allowed and over-water structures; E.10. Transportation d. trails. In addition, pursuant to the Vegetation Conversation Buffer Standard for Reach C of the Cedar River, the SMP identifies enhancement of native riparian vegetation should be implemented as part of management of public parks. Enhancement of the native riparian vegetation in the vicinity of the project is proposed by the applicant; see further information in the Environmental Review Report attached.

The City's Park Maintenance Department also utilizes the bridge to access Riverview Park with their maintenance vehicles. The bridge crosses the Cedar River, in Reach C, where the north bank is designated Shoreline High Intensity and the south bank is designated Urban Conservancy. Riverview Park is zoned Resource Conservation (RC) and is 11.53 acres in size. The project would impact 6,000 SF for the bridge replacement and 19,873 SF for shoreline vegetation plantings and enhancement. The bridge is also located in an area identified to have geological hazards including seismic hazards, regulated slopes (sensitive and protected), and moderate landslide hazards. The bridge would span the Cedar River which contains both the floodway and the 100-year flood plain. Finally, the park is located in Aquifer Protection Zone l. The existing bridge is 12 feet wide and 135 feet long constructed with a concrete deck and supported with fourteen 12-inch diameter timber creosote piles and one 12-inch diameter steel pile. Five of the piles are located in the middle of the riverbed and are frequently impacted by floating debris. Five additional piles are located on the north bank and five on the south bank. On each bank immediately upstream of the bridge there are deflection walls protecting the piles on the bank. The south deflection wall is constructed with three lfi-inch diameter timber creosote piles and horizontal timbers while the north deflection wall is constructed with three 12:inch diameter timbefcrei:r5ote'j:l11es'andhorizontal timbers. Each end oHFie ' · existing bridge connects to a concrete abutment at the top of the river bank that connects to the sidewalk system_ Demolition of the existing bridge is planned for July 1 -August 31 of 2014. Following demolition of the existing bridge, the replacement bridge would be constructed of aluminum providing a clear span of the Cedar River. The new bridge would be 10 feet wide and 135 feet long with a grated deck and would be supported by concrete abutments at the top of the river bank, in the same location as the existing bridge. The abutments would be supported by piles and would consist of two subgrade 12-inch diameter steel piles with a concrete pile cap surrounded by concrete back and wingwalls. The new bridge, like the existing bridge, would be intended to be used for pedestrians only, with the exception of Parks maintenance vehicles. The demolition of the existing bridge would result in the removal of 18 piles currently below the Ordinary High Water Mark (OHWM) and the concrete abutments. The north deflection wall would remain and continue to offer bank protection beneath the new abutments_ The south deflection wall is in poor condition and is proposed to be removed. The existing bridge contains utilities hung beneath; these utilities would be disconnected during construction and reconnected upon completion of the new bridge. The north bank of the Cedar River is currently vegetated with mostly native plants with pockets of invasive species such as blackberry and Japanese knotweed. The vegetation on the south bank consists more of invasive species than native. The applicant provided a vegetation restoration plan with the application to restore vegetation disturbed during construction and the removal of invasive species at several locations along both river banks. The total area to be enhanced with native vegetation is 19,873 SF.

Environmental Impacts The Proposal was circulated and reviewed by various City Departments and Divisions to determine whether the applicant has adequately identified and addressed environmental impacts anticipated ta occur in conjunction with the proposed development. Staff reviewers have identified that the proposal is likely to have the following probable impacts: 1. Earth Impacts: The subject site located in an area identified to have geological hazards including seismic hazards, regulated slopes (sensitive and protected), and moderate landslide hazards. As such the ERC Report 14-000480.docx City of Renton Department of Community & Ee, RIVERVIEW PARK BRIDGE REPLACEMENT Report of May 12, 2014 ic Development onmental Review Committee Report WA14-00048a Page4 of9 applicant provided a Geotechnical Investigation Report, prepared by PND Engineering, Inc., dated April 2014. The provided report addresses slope stability, seismic hazards, and structural recommendations for the new clear span bridge. PND Engineering conducted four boreholes at the project site during January of 2014. Three of the four borings were located in the vicinity of the north bridge. abutment and one is located in the vicinity of the south bridge abutment. Three borings were completed along the north bridge abutment because PND Engineering experienced difficulty drilling in this area. These borings were drilled to about 27 feet below the ground'surface and were terminated due to the difficult drilling conditions. The result of the borings along the north bridge abutment concluded that the subsurface conditions comprised of 6-7 inches of Portland cement concrete, followed by medium dense sand with variable gravel and wood debris in the upper 10 feet, underlain by surficial layer of medium dense sand with variable gravel and wood debris, dense to very dense gravel with sand was encountered to the full depth of borehole. The boring completed along the south abutment included 6 inches of Portland cement concrete, underlain by sand and gravel to about 37 feet below the ground surface which progressively became denser from medium dense to very dense with depth. Layers of very stiff to hard silt and clay were encountered below 37 feet to the maximum depth drilled 62 Y, feet. Pursuant to the provided report the riverbank slopes adjacent to the bridge abutments are approximately 15 to 20 feet in height and are inclined at about 11/2 H: 1V. These banks are considered to be both sensitive slopes and protected slopes pursuant to RMC 4-3-050 Critical Areas. Development is not permitted on protected slopes; however the applicant has proposed a clear,pan bridge and has indicaterrin'theapplication materials that impacts are·not·proposeti'to~~.' the existing protected slopes. The provided Geotechnical Study addresses slope stability and concludes that the proposed bridge replacement would not significantly affect the stability of the existing riverbank slopes or increase the threat of other geologic hazards, provided best management practices are followed and bridge foundation elements are designed and constructed as recommended in the report. The applicant has indicated in the provided SEPA Checklist that the only earthwork proposed would be for the construction of the abutments. In order to drive the foundation piles and set the concrete caps and sidewalk it is estimated that 25 cubic yards of material would be excavated on each side of the bridge and 12 cubic yards of structural fill would be imported for each abutment. In addition to the slope stability recommendations provided in the Geotechnical Report recommendations are provided for the successful design, construction and long-term performance of the proposed.project. These recommendations included but are not limited i:o site preparation and earthwork, subgrade preparation, structural fill, excavation, trenching and shoring, bridge foundation considerations, pile foundation design, and pavement recommendations. Finally, the provided Geotechnical Report addresses potential seismic hazards at the project site. The identified seismic hazards include liquefaction, lateral spreading, and fault rupture. PND's evaluation indicates that because the riverbank slopes are not saturated and due to the prevalence of dense to very dense gravel within the site soils there is a low potential for liquefaction. The report concludes that because ofthe low potential for liquefaction the site would also have a low risk of liquefaction-induced ground disturbance including lateral spreading. Overall the report indicates that the nearest mapped fault is located about 3 miles from the project site and due to the absence of mapped faults across the site it is PND's opinion that the risk for fault displacement resulting in ground rapture at the surface is remote. Due to the recommendation included in the ERC Report 14-000480.docx City of Renton Department of Commun;ty & Ee RIVERVIEW PARK BR!DGE REPlACEMENT ic Development ronmentaf Review Committee Report LUA14-000480 Report of May 12, 2014 provided Geotechnical Report and the presence of geological hazards, staff recommends a mitigation measure that the applicant comply with the recommendations included the geotechnical report_ Page5of9 Mitigation Measures: The applicant shall comply with the recommendations included in the Geotechnical Investigation Report, prepared by PN D Engineers, Inc., dated April 2014.

Wetland, Streams, Lakes Impacts: The Cedar River is a shoreline of the State and therefore subject to the Shoreline Master Program. The existing pedestrian bridge crosses the Cedar River, in Reach C, where the north bank is designated Shoreline High Intensity and the south bank is designated Urban Conservancy. The Cedar River is located within the Water Resource Inventory Area (WRIA) 8, Cedar-Sammamish Basin. The applicant provided a Stream Report prepared by Hart Crowser, dated March 28, 2014. Pursuant to the provided stream report the existing bridge was built in the early 1960s and has been repeatedly damaged by floating debris during high water events which required emergency repairs each time. Log jams have historically formed beneath the bridge during these events causing dangerous conditions. The proposed new bridge is designed to be a clear span bridge with a grated deck surface. The clear span would offer habitat improvements by removal of creosote- treated piles in the stream channel and freeing up river bottom and waterway for fish migration. --~·-''"::: ;.. ·: .;;_ ,~.;: ·_; _-::...:..,, -.• -:;-·.

The river channel substrates are comprised primarily of cobble and gravel between about 0-5 and 4 inches in diameter. The maximum water depths within the project area at the OHWM are approximately 4 feet. The stream report identifies that important ecological functions within the stream channel of the project area include spawning grounds for Chinook, coho, and sockeye salmon. The proposed project includes the removal of creosote-treated piles below the OHWM. The provided study evaluated construction disturbance resulting from the removal of the piles. According to the provided stream study, the noise and construction disturbance is expected to be minor, but may result in the temporary avoidance of the project area by fish. Potential effects will be minimized by implementing all in-water work during agency-approved work windows (July 1- August 31). No in-water pile driving would occur as a result of the replacement bridge and existing creosote-treated piles would be removed with a vibratory pile driver, thus minimizing the disturbance to any juvenile fish in the area. The report states that the removal of the in-water piles would eliminate a potential long-term source of contamination to the river in the project area. The short-and long-term effects of pile removal to stream habitats and biota are expected to be minimal or positive as the removal of 14 treated wood piles and one steel pile would increase the amount of stream channel habitat that can be used for aquatic insects and other invertebrate colonization, salmon spawning, and rearing juveniles by approximately 11.8 square feet. The removal of the existing deflection wall and near bank piles would likely improve edge habitat for juvenile fish and the removal of mid-channel piles would likely improve potential spawning habitat and remove potential impediments to migration. Finally the design of the new dear span bridge ERC Report 14-000480.docx City of Renton Department of Community & _Ee RIVERVIEW PARK BRIDGE REPLACEMENT Report of May 12, 2014 ic Development ronmental Review Comm;ftee Report WA14-000480 Page 6 of 9 would include a grated decking which would improve light penetration to the stream channel and reduce sharply contrasting shadows, thus improving primary productivity and reducing impediments to migration in the stream reach. The applicant has proposed to utilize the vibratory pile removal technique for pile removal which may result in temporary and localized increase in turbidity that may result in avoidance of the immediate area by juvenile and adult salmon ids. The report concludes that is it unlikely that any short-term and localized elevated turbidities generated by pile removal operations would directly effect salmonids or other fish species that may be present during construction. Furthermore, turbidity is no expected to be high given the cobble/gravel substrates at the location of existing piles. Overall the stream report identifies the proposed pedestrian bridge replacement has been designed with several conservation measures and best management practices to preserve and improve existing ecological functions within the riparian zone and stream channel over existing conditions at the site (see list of conservation measures in Exhibit 10). The stream study concludes that the proposed project would meet the criteria of "no net loss of ecological function" because of design consideration, conservation measures, and best management practices, the net effect of the bridge replacement project in the project and action area would be to maintain or improve the overall habitat quality for listed species relative to current conditions. Based on the recommendations for best management practices, project construction, design and mitigation staff recommends a mitigation measure that the applicant comply with the recommendations included in the stream study.

Nexus: SEPA Environmental Regulations, Shoreline Master Program. b. Storm Water Impacts: The subject project is located within the floodway and the 100-year flood plain of the Cedar River. It is anticipated that the proposed project would not impact the floodway and/or flood plain as the applicant are proposing to remove piles from within the floodway and replace the bridge with a clear span bridge (i.e. no new piles would be added tci the river). The bridge is proposed to be constructed a minimum of 3 feet above the 100-year flood level. Mitigation Measures: No further mitigation required Nexus: N/A 3. Vegetation Impacts: Within the project area, the banks on both side of the river are steep, but highly vegetated. The trees present within the riparian zone in the vicinity of the pedestrian bridge include black cottonwood, red alder, and big leaf maple that range in size from 10 to 30 inches in diameter at breast height. Other species growing within the project area include willows and smaller red alders, sward fern, along with invasive species such as English ivy, Japanese knotweed, holly and Himalayan blackberry. The provided stream study indicates that the riparian plant communities support numerous ecological functions including bank stabilization through root strength, sediment deposition on floodplains during periods of overbank flow, interstitial flow through the sediments, and large wood supply which has a substantial influence on channel complexity and in stream habitat features.

Furthermore, the applicant has proposed enhancement plantings in the project area of 19,873 SF in size. Based on the provided landscape plans (Exhibit 8) the planting plan would comprise of a combination of upland lawn restoration area (in the developed park), top of bank plantings, mid bank restoration plantings, and low bank plantings. A plant schedule was provided which identifies a list of plants that would be included in each planting zone. In addition, the area identified for restoration plantings would include invasive plant removal. A comment was received from the Muckleshoot Tribe requesting a detailed planting plan (Exhibit 12) which included removal of knotweed and additional native conifers along the river bank. Based on the provided plant schedule both Grand Fir and Douglas Fir would be included in the mixture of plants to be installed in the top of bank and mid-bank restoration plantings. Based on the applicant's plan to establish native conifers and provide invasive plant removal including but not limited to knotweed it would appear the subject project would meet the intent of the comments received from the Muckleshoot Tribe. Mitigation Measures: No further mitigation required Nexus: N/A 4. Wildlife Impacts: The stream study provided with the application identified that the Cedar River is home to at least 19 resident species of fish including but not limited to rainbow and cutthroat trout, mountain whitefish, large-scale sucker, Chinook salmon and sockeye salmon. The riparian C ·--vegetatioiYirrlhe-pfojettarea·'could include species such as olack-tailed de'i:!r;tnuskraf,"raccoon;· -- striped skunk etc. The subject project is located in the flood way and the 100-year flood plain of the Cedar River; as such the applicant is required to submit a Biological Evaluation (BE) in compliance with Section 7 of the Endangered Species Act (ESA). The applicant provided a Biological Evaluation prepared by Hart Crowser, dated March 26, 2014. The BE indicates that the subject project work would occur on the Cedar River which has the potential to impact two species listed as threatened or endangered under ESA, or their critical habitat: Puget Sound Chinook salmon and Puget Sound steel head trout. The BE also looked at USFWS list of federally listed species that occur in King County and determined that the species listed by USFWS would inhabit areas along the Cascade foothills and mountains. None of these habitats are present at the project site and therefore the BE concludes that there would be no effect on these species. The BE evaluates Chinook Salmon, Steelhead Trout, and Bull Trout and their Critical and Essential Fish Habitat (EFH). Section 4.0 includes an evaluation of the effects ofthe proposed project on these listed species. This section looks at the short-term, long-term, and net effects of construction disturbances, water quality, sediment quality, and habitat and Biota. The BE indicated the net effect of the overall proposed action would be to maintain or improve the overall habitat quality for listed species relative to current conditions. Moreover the BE concludes that the effects from the proposed project activities would be minor, temporary, and highly localized to the immediate pile removal footprint with,in the Cedar River. Turbidity would be highly localized and temporary and noise would be limited to those emanating from vibratory pile removal during approved in- water work windows. Ultimately, pile removal would improve both spawning and rearing habitats in the long-term. Therefore the subject project may affect, but is not likely ta adversely affect, ERC Report 14-{)()1)480.docx City of Renton Department of Community & fC( RIVERVIEW PARK BRIDGE REPLACEMENT Report of May 12, 2014 ic Development anmental Review Commhtee Report LUA14-000480 Page 8 of9 Chinook salmon and steelhead trout or their designated or proposed critical habitat. For the same reasons, proposed project actions would have no effect on EFH within the project and action areas. In addition to the evaluation of listed species the BE identifies impact avoidance, minimization and conservation measures for the proposed project. The list of measures can be found in Exhibit 11. Due to the recommendation included in the BE staff recommends as a mitigation measure that the applicant comply with the impact avoidance, minimization and conservation measures identified in the BE. Mitigation Measures: The applicant shall comply with the recommendations included in the Biological Evaluation, prepared by Hart Crowser, dated March 26, 2014. Nexus: SEPA Environmental Regulations, ESA Section 7, RMC 4-3-050 Critical Areas. 5. Parks and Recreation Impacts: The subject project is anticipated to have limited impacts to Riverview Park during construction. According to the submitted construction mitigation description the parking lot and the entire park would be closed to the public during demolition and construction of the bridge. The park would be open during the period between demolition and construction. However, the adjacent Cedar River Trail is expected to remain open at all times throughout the project with only minor impacts during transport of equipment. The construction phasing plan submitted with the application indicates that demotion of the existing bridge is estimated to occur between July 1 and August 31 of 2014 and would be approximately 3-4 weeks long. The construction of the new bridge would be the same months as the demolition the following year (2015). ;.,c .J'.•'l!ijgaj:!oo !)lleasures: No further rnitig,!tion required-., Nexus: N/A 6.

Exemption Basis: The project represents Normal Maintenance and Repair and is exempt under WAC: 173-27-040(2W>): Normal maintenance or repair of existing structures or developments. Normal maintenance or repair of exfrtin,~ strudures or developments, indudin,g dam«ge by aaident, _fire or elements. "Normal maintenance" includes those usual acts to prevent a decline, lapse, or ,~ssation from a lawfully established conddion. "Normal repair" means lo restore a development to a state comparable to its original condition, inc!udin,~ but not limited to its size, shape, configuration, location and external appearance, within a reasonable period after decay or partial destruction, except whe,e repair causes substantial adverse ejjects to shoreline resource or environment. Rep/ac,ment ofa structure or development may be authorized as repair where such replamnent is the common method of repair for the type of strttdure or development and the replaament .1/mdure or development is compurable to the original structure or development including but not limited to its size, shape, configuration, location and external appearance and the replm~ment does not cause St1bstantial adverse effects to shoreline resources or environment; Current Use: The existing bridge connects the parking lot to Riverview Park and provides access to the Cedar River Trail system. It is used primarily for pedestrian traffic, but also provides access for maintenance vehicles. It is 12 feet wide and approximately 135 feet long with a concrete deck supported on piles. There arc fourteen 12-inch diameter timber creosote piles and one 12-inch diameter steel pile. Five of these piles are in the middle of the riverbed an<l arc frequently impacted by floating debris sometimes resulting in serious logjams. There are also five piles on the north bank and five on the south bank. On each bank immediately upstream of the bridge, there is a deflection wall protecting the piles on the bank. The south wall consists of three 16-inch diameter timber creosote piles an<l horizontal timbers while the north wall consists of three 12-inch diameter timber creosote piles and horizontal timbers. Each end of the bri<lgc connects to a concrete abutment at the top of the riverbank that connects to the sidewalk system. Several utility lines including water, sewer and electric run along the underside of the bridge. The riverbanks are steep with evidence of past armoring in some areas. Vegetation on the north bank is mostly native with pockets of invasive species such as blackberry and Japanese knotweed. Vegetation on the south bank consists more of invasive species than native. Description of Proposed Project Work: The proposed use will not change. The project includes replacing the bri<lge with a new aluminum clear span bridge at the same location. The clear span will remove 18 piles currently at or below Ol-lW subsequently eliminating any future logjam potential. All work will be accomplished using land-based equipment. Demolition of the existing bridge includes 1736 FOURTH AVENUES, SUITE A, SEATTLE, WASHINGTON 98134 I phone, 206.624.1387 I fax, 206.624.1388 Pagc2of2 April 10, 2014 Riverview Bridge Replacement removal of the fiticcn support piles and concrete abutments. '!'he north deflection wall will remain and continue to offer continued bank protection beneath the new almtme1Hs. The south deflection wall is in very poor condition and will be removed.· !'he new aluminum bridge will be 10 feet wide and 135 feet long with a grated deck and will be supported by concrete abutments at top of bank. The abutments will be pile supported. Each abutment will consist of two subgrade 12-inch diameter steel piles with a concrete pile cap surrounded by concrete back-and wingwalls. Existing utilities will be hung from the new bridge and reconnected. During demolition and construction, the public toilet will be temporarily closed and the Parks Division will make a portable toilet available to park users. A vegetation restoration plan is included as part of the project to restore vegetation disturbed during construction. Rcrnoval of invasive species will occur in several locations both on and adjacent to the riverbanks. These areas will be densely planted with native species. To insure acceptable plant survival, it is anticipated that both existing and tempora1·y irr·igation will be utilized. The total area to be enhanced or replanted is 19,873 SF (see sheet L.4 of the plan set). Site Access: The existing bridge serves as pedestrian and park maintenance access to the park. This will not change upon completion of the project. Most construction access will occur from the existing Riverview Park parking area off of SR 169. Certain equipment that needs to access the south side of the river will be brought in via the Cedar River Trail from the parking area located near I -405. During equipment transport on the trail, flaggers will be present in order to direct trail users safely around the equipment. For more details on construction access, please see the Construction Mitigation Description (also submitted) and Preliminary Traffic Control Plan. Schedule: Demolition would occur sometime between July 1 and August 31, 2014. Construction would occur between July 1 and August 31, 2015. Plantings would follow during the fall planting season. Other Permits Required: • Hydraulic Project Approval (WDFW) • Right of Entry Permit (DNR) • Section 404 (US Army Corps) -this has not been confirmed. Corps staff will determine upon submittal of documents. • Building Permit (City of Renton) • Demolition Permit (City of Renton) Special Features: The project occurs over and within the Cedar River. The riverbanks arc steeply sloped. Soils and Drainage: The geotechnical investigation revealed medium dense sand with variable gravel and some wood debris. Underlying the surficial layer of medium dense sand with variable gravel and wood debris, dense to very dense gravel with sand was encountered to the full depth of the borehole. Per the USDA online soils mapping application, the general area of the site consists of Puyallup fine sandy loam (http: //websoilsun·c,,.sc.e)!OI' .usda.)!O\' L \pp/WebSoilSm,·e\.aspx). The abutment areas and bridge location is not prime farmland as it is a river and riverbank. Drainage is infiltrated into the vegetated areas. Estimated Cost: $1.167 M Page 3 of 2 April 10, 2011 Rivcn,icw Bridge Replacement Estimated Cut/ Fill Quantities: The only earthwork proposed with this project is for the abutments. In order to drive foundation piles and set the concrete caps and sidewalk, approximately 25 CY of material will be excavated on each side. A pproximatcly 12 CY of structural fill will be imported for· each abutment. Fill will be sourced by the contractor from an approved source. Tree Removal: none proposed. OHW Work: Pile removal will occur below OHW. All other work will occur above OHW. Existing shoreline: r\ t this location, the Cedar River's banks are steeply sloped (15-20 feet). There is evidence of past armoring.

Permits\City App Material\SEPA Checklist 03-25-14 Riverview.doc The existing bridge was built sometime in the early 1960s and has been repeatedly damaged by floating debris during high water events requiring emergency repairs each time. Log jams have historically formed beneath the bridge during these events causing dangerous situations. In order to eliminate future damage and dangerous situations, the bridge will be replaced with a clear span structure so there will be nothing in the waterway for debris to hit or get trapped on. There will be no change in use. The clear span will also offer habitat improvements by removal of creosote timbers in the waterway and freeing up river bottom and waterway for fish migration. The existing solid concrete deck 135'x12' bridge and (15) piles will be removed and a new clear span aluminum bridge (135'x10') with a grated deck will be installed in the same location. The existing (3)-pile deflector wall on the south bank will be removed. The north (3)-pile deflector wall will remain. The sidewalk will be cut where it connects to the bridge at the top of the bank slope. The new bridge will be supported on foundations constructed at the top of the bank. Each abutment will consist of (2) 12-inch diameter steel piles driven at the top of the slope. Sidewalk will be replaced in the same location. Native vegetation will be planted on all sides immediately adjacent to the new bridge. 12. Location of the proposal. Give sufficient information for a person to understand the precise location of your proposed project, including a street address, if any, and section, township, and range if known. If a proposal would occur over a range of area, provide the range or boundaries of the site(s). Provide a legal description, site plan, vicinity map, and topographic map, if reasonably available. While you should submit any plans required by the agency, you are not required to duplicate maps or detailed plans submitted with any permit applications related to this checklist.

General description of the site (circle one); llli!I, rolling, hilly, !steep slopd, mountainous, other _____ _ The upper areas of the park site is relatively flat, however the river channel has carved out steep banks between 15 and 20 feet high. b. What is the steepest slope on the site (approximate percent slope?) The riverbank slopes adjacent to the two bridge abutments are approximately 15 to 20 feet in height and are inclined at about lYzH:1 V (horizontal to vertical). The slopes are locally steeper in some areas and some evidence of erosion was noted on the slopes during visits to the site. The steepest percent slope is approximately 67%. . 3 -06109 J:\2013 Project Files\134057.01 Riverview Park Bridge\F. Permils\Ci1y App Material\SEPA Checklist 03-25-14 Riverview.doc c. What general types of soils are found on the site (for example, clay, sand, gravel, peat, muck)? If you know the classification of agricultural soils, specify them and note any prime farmland. The geotechnical investigation revealed medium dense sand with variable gravel and some wood debris. Underlying the surficial layer of medium dense sand with variable gravel and wood debris, dense to very dense gravel with sand was encountered to the full depth of the borehole. Per the USDA online soils mapping application, the general area of the site consists of Puyallup fine sandy loam (http://websoilsurvey.sc.egov.usda.gov/App/WebSoilSurvey.aspx). The abutment areas and bridge location is not prime farmland as it is a river and riverbank. d. Are there surface indications or history of unstable soils in the immediate vicinity? If so, describe. Geologic hazard areas designated by Renton Critical Areas Ordinance No. 5137 regulates land development within and adjacent to areas defined by the ordinance as critical or sensitive areas. Geologic hazard regulations apply to areas defined by the ordinance as erosion, seismic, landslide, steep slope, and coal mine hazards. Based on the city of Renton Sensitive Areas Maps and site observations, the project area is classified as being within the following geologic hazard areas: • Regulated Slopes: Both riverbank slopes have areas mapped as Sensitive (25 to 40 percent) or Protected (40 to 90 percent) slopes (COR 2014). The City's mapping is consistent with the topography survey for the site which shows the slopes generally inclined at lY.H:1 V or approximately 37 percent grade. • Landslide: The area south of the bridge including shoreline is mapped as moderate landslide hazard area (COR 2014). • Seismic: The project area is within a mapped seismic hazard area (COR 2014); however, based on the ordinance (COR 2004) the site is classified as "Low Seismic Hazard" because it's underlain by dense soils. • The site does meet geologic hazard designations pursuant to the City of Renton regulations for coal mine or erosion hazard. e. Describe the purpose, type, and approximate quan.tities of any filling or grading proposed. Indicate source of fill. The only earthwork proposed with this project is for the abutments. In order to drive foundation piles and set the concrete caps and sidewalk, approximately 25 CY of material will be excavated on each side.

The existing bridge is a five-span steel girder bridge with a concrete deck and is supported on (14) in-water, creosote-treated, timber piles and one (1) steel pile. The proposed replacement bridge will be a single-span, aluminum arched thru-truss. The replacement bridge will span the floodplain. The impact of the replacement bridge on the floodplain will result in a slight reduction in the flood level immediately below and adjacent to the bridge by eliminating the in-water timber piles. The existing bridge low chord elevation is currently at elevation 59.5 (NAVD88). The base flood water surface elevation at the bridge is 54.5 (NA VD 88). The current, 30% level design shows a low- chord elevation of 59.5' (NAVD88). The final low-chord elevation will likely change as the design progresses, however, the final low-chord elevation will be greater than 3-feet above the 100-year base flood elevation of 54.5' (NAVD88) at the site. This will maintain adequate clearance between the 100 year water surface elevation and the low chord elevation. The proposed bridge reduces the risk of the bridge being damaged during 100-year flood or larger floods in the future. Elevations are shown in the plan set submitted to the City Planning Department. r<EC:EIVED .il.PR 1 1 ZO!L C!rY OF RENTON PU\l'..;'i\J:NG D!V'S!ON 1736 l•'ourth Avenue S. • SEATfl.l\ WA 98134 • phone: 206.624.1387 • fax: 206.624.1388 WASHINGTON STATE Joint Aquatic Resources Permit Application (JARPA) Form 1 ,2 lf.iiiF.il ~ us Army Corps of Engineers • Se.itne 0.sfnd USE BLACK OR BLUE INK TO ENTER ANSWERS IN THE WHITE SPACES BELOW.

[bt!Q] C2l Yes 0No D Don't know 51. Briefly describe the vegetation and habitat conditions on the property. [bt!Q] The Cedar River is a known salmon spawning river. At the project site, the river is approximately 100 feet wide at OHW. The banks on both sides are steep and vegetated. There is evidence of historic armoring of both banks. Native species such as sword fern, willows and large trees including oak, poplar, hemlock and alder are present. There are also several invasive species present including English ivy, Japanese knotweed, holly, and Himalayan blackberry. The streambed consists of medium sized cobbles and gravels. 5m. Describe how the property is currently used. [bt!Ql The property is a public park (Riverview Park) owned by the City of Renton. The bridge connects the parking area north of the river to the park on the south side of the river. The regional Cedar River Trail can also be accessed from the park on the south side of the bridge. 5n. Describe how the adjacent properties are currently used. [bt!Ql Immediately to the north, the property is bounded by State Route 169 (Maple Valley Highway). North of that is a cluster of single family homes. The state owned Cedar River Trail ROW bounds the site to the south. To the east and west is more City owned parks property. 5o. Describe the structures (above and below ground) on the property, including their purpose(s) and current condition. [help] There are two structures in the immediate vicinity. 1. Existing bridge-concrete deck, pile supported bridge approximately 135 feet long x 12 feet wide. It is supported on three pile bents. The north and south bents each consist of (5) 12-inch diameter timber creosote piles. The mid-span bent consists of (4) 12-inch diameter timber creosote piles and (1) 12-inch diameter steel pile. The bridge provides access across the river to the park and Cedar River Trail. Utilities including sewer and water are hung beneath it to serve the park facilities. The bridge has required emergency repairs several times as a result of damage to the piles from large logs floating down the river during high water events. 2. Existing toilet -this is a public toilet that serves the park users. It will not be affected by the proposed project except for a temporary interruption in utility service.

You can provide more detail in 6b. llllilm The existing solid concrete deck 135'x12' bridge and (15) piles will be removed and a new clear span aluminum bridge (135'x1 O') with a grated deck will be installed in the same location. The existing (3)-pile deflector wall on the south bank will be removed. The north (3)-pile deflector wall will remain. The sidewalk will be cut where it connects to the bridge at the top of the bank slope. The new bridge will be supported on foundations constructed at the top of the bank. Each abutment will consist of (2) 12-inch diameter steel piles driven at the top of the slope. Sidewalk will be replaced in the same location. Native vegetation will be planted on all sides immediately adjacent to the new bridge. 6b. Describe the purpose of the project and why you want or need to perform it. [!llilm The existing bridge was built sometime in the early 1960s and has been repeatedly damaged by floating debris during high water events requiring emergency repairs each lime. Log jams have historically formed beneath the bridge during these events causing dangerous situations. In order to eliminate future damage and dangerous situations, the bridge will be replaced with a clear span structure so there will be nothing in the waterway for debris to hit or get trapped on. The clear span will also offer habitat improvements by removal of creosote timbers in the waterway and freeing up river bottom and waterway for fish migration. 6c. Indicate the project category.

[b&J.ill • Identify where each element will occur in relation to the nearest waterbody . • Indicate which activities are within the 100-year floodplain . Bridge Demolition: The bridge will be cut into sections and removed by land based cranes situated near the top of both bank slopes and accessed from the parking lot on the north side and the trail on the south side. No activity will occur in the water and debris will not be allowed to enter the water. Pile Removal: The same cranes will be used to pull the bridge piles using vibratory methods. In the event that any piles break or cannot be extracted, they will be cut as close to mudline as possible.

Describe how the project is designed to avoid and minimize adverse impacts to the aquatic environment. [b§m) D Not applicable JARPA Revision 2012.2 Page 8 of 15 The project as proposed will improve the Cedar River habitat. In order to avoid and minimize adverse impacts to the aquatic environment, the design has been kept to the minimum required to meet the needs of the Park. Several bridge design iterations were considered based on the following criteria: meeting design loads for the park users and maintenance equipment; regulatory requirements and ecological impacts to the river and shoreline environments. Alternatives considered included various bridge and deck materials, abutment types and configuration were all examined. In order to eliminate any pile being driven in the water the pile supported abutments were placed well above OHW. The entirety of the bridge deck will be light penetrating grated aluminum. Since water will also pass through the grating, plantings can be added beneath the bridge. Piles will be installed using vibratory methods to the extent possible followed by impact proofing that will be kept to a minimum. No pile driving will occur in the water. The low cord of the new bridge is above the based flood elevation to avoid any flood impacts. In order to avoid and minimize adverse impacts to the aquatic environment typical construction BMPs for working over, in, and near water will be applied, including but not limited to the following measures: Construction Measures: 1. In water work timing restrictions as proposed and approved will be adhered to. 2. All manmade construction debris will be collected and not allowed to enter waters of the state. 3. Methods for containing debris during overwater demolition work may include use of tarps or shrouds. Other methods may be identified by the Port or contractor. 4. Land based equipment will not be operated on the substrate below the waterline. 5. Project construction will be completed in compliance with Washington State Water Quality Standards WAC 173-201A. 6. Contractor will check equipment for leaks and other problems that could result in discharge of petroleum- based products, hydraulic fluid, or other material to the Cedar River. 7. Contractors conducting in-water and over-water work, including demolition, will be familiar with implementation of BMPs and permit conditions typical of working in the aquatic environment. 8. The contractor will have a spill containment kit, including oil-absorbent materials, on site to be used in the event of a spill or if any oil product is observed in the water. 9. Pile will be removed using vibratory extraction to greatest extent possible. Pile which cannot be extracted will be broken/cut off at the mudline. 10. Pile will be removed slowly so as to minimize sediment disturbance and turbidity in the water column. 11. Prior to extraction the operator will "wake up" pile to break bond with sediment to break the friction between the pile and substrate to minimize sediment disturbance. 12. Where possible, extraction equipment will be kept out of the water to avoid "pinching" pile below the water line in order to minimize creosote release during extraction. 13. Pile will not be broken off intentionally by twisting, bending or other deformation in order to minimize creosote release during extraction. 14. Upon removal from substrate the pile shall be moved expeditiously from the water into an upland area. The pile shall not be shaken, hosed-off, stripped or scraped off, left hanging to drip or any other action intended to clean or remove adhering material from the pile. 15. All creosote treated pile removed will be disposed of at an appropriate upland facility. Design Features: 1. New bridge deck will be constructed of grated material to allow for light penetration to the water and streambanks. 2. No piles will be installed in the waterway and all existing bridge piles and the deflector wall piles on the south side will be removed from the waterway. Sb.
