The Seattle District, U.S. Army Corps of Engineers (USACE), Regulatory Branch is implementing an interactive web -based mitigation bank tracking system known as the Regional Internet Bank Information Tracking System (RIBITS).1 Many USACE districts have already implemented RIBITS, and it has proven to be a very successful tool for the commercial bankers, the public, and the governmental agencies associated with tracking mitigation banks and compensatory mitigation credits for approved mitigation banks. The information contained in RIBITS is in accordance with 33 CFR parts 325 and 332 and 40 CFR part 230, Subpart J, "Compensatory Mitigation for Losses of Aquatic Resources; Final Rule, (Rule) published in the Federal Register on April 10, 2008. RIBITS will allow everyone, including the public and all governmental entities, to track the status of USACE approved mitigation banks in Washington. The website will also allow the public to -identify those banks that provide a given type of compensatory mitigation (wetland, stream, or species) and present detailed information on banking processes and procedures. Ultimately, RIBITS will provide up-to-date mitigation banking information to bank sponsors, permit applicants, and the general public. The website will publicize bank specific information to include: service area boundaries; sponsor information (to include the. company name, point of contact, address, and telephone. number); the USACE Co -Chair assigned to each bank; the Interagency Review Team (IRT) and respective contact information; total acres within the bank site; bank type (private commercial or public commercial); total released credits; total potential credits; credit release schedules; credit ledger (to include transaction type, date of transaction, number of credits initiated, released, and/or withdrawn for each transaction); total credits withdrawn; balance of released credit; balance of maximum potential credits; and types of credits (wetland, stream, or species). RIBITS will also include a cyber repository (electronic copies of the final mitigation banking instrument (MBI) and associated appendices which will include site performance standards, credit release schedules, baseline site evaluations, monitoring requirements, ledger reports pertaining to mitigation credits, credit release requests); monitoring reports; service area maps; and any MBI modifications. t RIBITS .was developed by the U.S. Army Corps of Engineers' Engineer Research and Development Center (ERDC) -and Applied Research Associates, with support from the U.S. Army Corps of Engineers' Regulatory Program Headquarters and the U.S. Environmental Protection Agency.

This action was taken on the following application: APPLICANT: WSDOT PROJECT: Springbrook Creek Wetland Mitigation Bank DEVELOPMENT DESCRIPTION: The Washington State Department of Transportation (WSDOT) is requesting Shoreline Substantial Development Permit approval for the development of the Springbrook Wetland and Habitat Mitigation Bank (Springbrook Bank) by re-establishing, rehabilitating, enhancing, and preserving 131.54 acres of wetland and riparian area. The proposed bank will increase overall wetland area, hydrologic functions, water quality functions, habitat functions, and provide passive environmental education opportunities. The purpose of the Bank is to provide compensatory mitigation in advance of unavoidable impacts to wetlands and other aquatic resources from future projects within portions of the Cedar-Sammamish Watershed and the Green-Duamish Watershed. The Springbrook Bank is composed of 5 sites, labeled Units A through E (see attached description). Construction of the Springbrook Bank would include extensive site grading on Units C and E; breaching the existing earthen berms adjacent to Springbrook Creek on Units A, B, and E; removal and control of invasive reed canary grass in Units A, B, and C; constructing an elevated boardwalk trail on Unit A; installing habitat structures; and planting native woody vegetation on all units. This work is intended to enhance a broad range of ecological functions to improve wetland habitat, water quality, and hydrologic functions. Units A, B, C, and E are identified on the City's Shoreline Boundary Map as containing wetlands that are State Shorelines as they are associated with Springbrook Creek. Unit D does not have wetlands associated with Springbrook Creek, however a portion of the 200-foot Shoreline buffer from Springbrook Creek extends onto the site. Units A, B, and E are classified as Conservancy Shoreline Environments and Units C and D are classified as Urban Shoreline Environments.

Capital Way, Suite 106 Olympia, WA 98504-8343 RE: WSDOT Springbrook Creek Wetland and Habitat Mitigation Bank Project Log #: 110805-05-FHWA Dear Dr. Brooks: Per provisions of 36CFR800, we are continuing consultation for the above project. Enclosed please find a copy of Historical Research Associates' (HRA) technical report (I-405, Springbrook Creek Wetland and Habitat Mitigation Bank Project: Final Historical, Cultural, and Archaeological Discipline Report, dated November 2005) summarizing their cultural resources investigations for the above project. As you will note in the report, the consultants did not identify any cultural resources during their systematic survey the 130-acre Springbrook Mitigation Bank Site. The results of HRA's investigation confirms that the Springbrook Bank project APE is archaeologically sensitive because Springbrook Creek is a tributary of the Green River and both waterways are associated with known archaeological sites and traditional tribal place names. Although field investigations, which incorporated subsurface probes, failed to identify any archaeological resources in the APE, the planned wetlands re-establishment efforts may still have the potential to impact any undiscovered, deeply buried archaeological resources. Therefore, during construction, WSDOT recommends that a qualified archaeologist will monitor project units where re-establishment activities are planned. For the remainder of the Springbrook Bank project areas, WSDOT will incorporate an Inadvertent Discovery Plan for implementation of the Springbrook Bank project. WSDOT will continue consultation with DAHP during the development of the monitoring and inadvertent discovery plans. We look forward to your concurrence our determination of No Historic Properties Affected for this project. We respectfully request your response and comments by January 24, 2006.

Give brief, complete description of your proposal, including the proposed uses and the size of the project and site. 00 There are several questions later in this checklist that ask you to describe certain aspects of your proposal. You do not 01 need to repeat those answers on this page. (Lead agencies may modify this form to include additional specific information 02 on project description.) 03 04 Background 05 WSDOT and the City of Renton, in partnership, are developing the Springbrook Wetland and Habitat Mitigation Bank 06 (Springbrook Bank) by re-establishing rehabilitating, enhancing, and preserving 131.54 acres of wetland and riparian area 07 located in the southwest portion of the Renton, Washington. The Springbrook Bank will increase wetland area, hydrologic 08 functions, water quality functions, habitat functions and provide passive environmental education opportunities. 09 2 10 The City of Renton owns the five land parcels (Units A, B, C, D, and E) that comprise the Springbrook Bank. The Springbrook 11 Bank is located in the Lower Green River Basin within Water Resource Inventory Area 9 (WRIA 9), as shown on Sheet VI. The 12 purpose of the Springbrook Bank is to provide compensatory mitigation credits for future unavoidable impacts to wetlands and 13 similar resources caused by WSDOT highway construction projects and other projects permitted by the City of Renton within the 14 service area of the bank. 15 16 Project Description 17 The proposed project focuses on improving wetland area and function, and riparian functions near Springbrook Creek. 18 Construction work includes extensive site grading on Units C and E; breaching the earthen berms adjacent to Springbrook Creek 19 on Units A, B and E; removal and control of invasive reed canarygrass in Units A, B, and C; constructing an elevated boardwalk 20 trail on Unit A; installing habitat structures; and planting native woody vegetation on all units. This work will enhance a broad 21 range of ecological functions to improve wetland habitat, water quality, and hydrologic functions. 22 23 Work will be done on the five parcels as follows: 24 25 Wetland Re -Establishment Areas: Removal of historically placed fill material will allow groundwater and surface water to 26 restore hydrology to former wetlands on Units C and E (Table 1). The excavation in Unit E includes removing sections of an 27 existing earthen berm to connect re-established wetlands on Unit E with Springbrook Creek (Sheet GR6). Native woody plant 28 species and habitat structures (including vertical snags, brush piles, and/or anchored logs) will be installed on Units C and E 29 (Sheets P4 and P6). These activities will restore wetland area, function, and value where wetlands formerly existed. 30 31 Wetland Rehabilitation Areas: Improving the hydrologic regime of existing wetlands (e.g., reconnecting floodplain wetlands on 32 Units A and B to Springbrook Creek, and providing additional hydrology to wetlands on Unit C) will facilitate the rehabilitation 33 of existing wetlands on Units A, B, and C (Table 1). Microtopography (planting hummocks) will be installed on Units A, B, and 34 C to provide additional habitat niches and hydrologic regimes, as well as facilitate conifer establishment (Sheets P1, P2, P3 and 35 P4). Native woody plant species and habitat structures will be installed in Units A, B, and C to improve species diversity and 36 habitat structure and complexity (Sheets P14). 37 38 Wetland Enhancement Type I Areas: Existing wetlands on Unit C will be enhanced by increasing plant and habitat diversity in 39 large areas of invasive non-native vegetation (reed canarygrass and Himalayan blackberry) through a combination of several 40 activities: implementing reed canarygrass removal and control measures; densely planting native trees and shrubs; placing habitat 41 structures; and installing planting hummocks in reed canarygrass removal areas (Sheets P3 and P4). These activities will increase 42 species diversity and habitat structure and complexity. 43 44 Wetland Enhancement Type II Areas: Supplemental hydrology will be provided to existing seasonally inundated areas on the 45 northern portion of Unit D (Table 1). The additional water will be redirected from an existing stormwater treatment pond located 46 at the southern end of Unit D via a new conveyance pipe to the northern end of Unit D (Sheet GR5). This additional hydrology 47 will supplement the existing hydrologic regime. 48 49 Forested Wetland Enhancement Areas: Native conifer plant species will be under -planted within the forested wetland portions 50 of Units C and D (Sheets P3, P4, and P5). This will enhance species and structural diversity in both units. 51 52 Upland Habitat Enhancement Areas: Removing invasive species and installing habitat structures will enhance upland habitat in 53 Units C and E (Sheets P3, P4 and P6). In addition, Unit C will be densely planted with native woody species and Unit E will be 54 under -planted with native conifer plant species in existing deciduous forest areas. 55 56 Riparian Upland Enhancement Areas: Establishing riparian vegetation through a combination of mowing/herbicide treatment 57 of reed canarygrass, clearing and grubbing other invasive, non-native vegetation, and planting native woody species will enhance 58 riparian function on Units A, B, and E (Table 1, Sheets P1, P2, and P6). Establishing woody species will also provide tree canopy 59 shade for Springbrook Creek. In Unit E, habitat structures will be placed in portions of the enhancement. 60 61 Protection Setback (Buffer): Portions of all units, except Unit D, will include 40-foot-wide perimeter buffers to be planted with 62 native woody species in both wetlands and uplands. This will promote structural diversity and protect habitat from disturbance 63 from adjacent land uses. 64 65 Table 1 provides a summary of treatment types and acreage amounts for the Springbrook Creek Bank. 66 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 00 01 02 03 Table 1 Habitat Treatment Type and Acreage Summary l l...._ ..... ...... --- - ... -- Acreage Habitat Treatment Type !

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. The Springbrook Bank project comprises five units, totaling 131.54 acres, south of SW 27th Street and west of Lind Avenue SW in the city of Renton (Sheets VI and T 1). Unit A is located in Section 30, Township 23N, Range 5E; Units B, C, and E are located in Section 25, Township 23N, Range 4E; Unit D is located in Section 36, Township 23N, Range 4E. Specifically, locations of the five units are as follows: Unit A is located between SW 27th Street, and SW 34th Street, west of Lind Avenue and east and adjacent to Springbrook Creek. The undeveloped site covers 26.33 acres and is bordered along its northern and eastern sides by road arterials serving industrial activities. The southern boundary is an undeveloped road right of way adjacent to industrial zoned property that is currently being developed. Unit A is bordered to the west by Unit B. Unit B is located immediately south of SW 27th Street, adjacent to Springbrook Creek, east of Oakesdale Avenue SW and north of the Seattle Times property. This 36.49-acre undeveloped site is bordered on the north and south by industrial development and on the east by Unit A. Unit C encompasses 47.90 acres. It is located east of the Burlington Northern Santa Fe (BNSF) Railroad and west of Oakesdale Avenue SW. North of the site is undeveloped land owned by the Boeing Company. South of the site is a railroad facility and undeveloped land. Unit D is a 5.60-acre site located immediately north of the land owned by City of Tukwila, which is a wetland mitigation site for the 180th Street grade -separation project. Unit E is a 15.22 acre undeveloped piece of property located south of SW 34th Street, west and adjacent to Springbrook Creek, north of SW 41 st Street, and east of Oakesdale Avenue SW. It is bordered to the north by developed light industrial zoned land. B. ENVIRONMENTAL ELEMENTS 1. Earth 4 04 a. General description of the site (circle one): Ifil rolling, hilly, steep slopes, mountainous, 05 other...... 06 07 b. What is the steepest slope on the site (approximate percent slope)? 08 09 The Springbrook Bank is located within the nearly flat Green River Valley. The only existing sloping areas at the 10 Springbrook Bank site are the sides of the earthen berms adjacent to Springbrook Creek on Units A, B, and E. These 11 slopes may range from I percent to approximately 40 percent. The steepest berm slopes are located on Site E. 12 13 c. What general types of soils are found on the site (for example, clay, sand, gravel, peat, 14 muck)? If you know the classification of agricultural soils, specify them and note any prime 15 farmland. 16 17 The King County Soil Survey describes four soil types at the Springbrook Bank site: Puget silty clay loam, Puyallup fine sandy 18 loam, Snohomish silt loam, and Woodinville silt loam. 19 20 d. Are there surface indications or history of unstable soils in the immediate vicinity? If so, 21 describe. 22 23 The City of Renton Critical Areas Ordinance maps indicate that all five parcels lie within a seismic hazard area. 24 25 e. Describe the purpose, type, and approximate quantities of any filling or grading proposed. 26 Indicate source of fill. 27 28 Approximately XX cubic yards of fill will be excavated to breach the berms in Units A and B (Sheets GRI and 2). 29 Approximately 110,000 cubic yards of fill in Unit C and 152,000 cubic yards in Unit E will be excavated to re-establish former 30 wetlands in those units (Sheets GR3, GR4 and GR6). In order to install a stormwater pipe to supplement hydrology to Unit D, 31 approximately XX cubic yards of fill will be excavated (Sheet GR5). 32 33 The existing conveyance ditch in Unit C will be plugged with approximately XX cubic yards of clean fill in order to redirect 34 surface hydrology into the wetland re-establishment area on Unit C (Sheets GR3 and GR4). 35 36 f. Could erosion occur as a result of clearing, construction, or use? If so, generally describe. 37 38 Some temporary erosion could occur during construction activities; however, erosion control measures and best management 39 practices (BMPs), such as placement of silt fences, will be utilized to control erosion and turbidity. Upon completion of 40 clearing/grubbing /grading and elevated boardwalk trail construction, the site will be re -vegetated with native vegetation, which 41 will prevent future erosion from occurring at the site. 42 43 g. About what percent of the site will be covered with impervious surfaces after project 44 construction (for example, asphalt or buildings)? 45 46 None. 47 48 h. Proposed measures to reduce or control erosion, or other impacts to the earth, if any: 49 50 High visibility temporary construction fencing will be placed around designated work areas to ensure no construction impacts will 51 occur beyond those designated work areas. Additionally, to prevent erosion and impacts to water quality, 52 clearing/grubbing/grading and elevated boardwalk trail construction will only occur during seasonally dry periods. Some 53 temporary erosion could occur during construction activities; however, erosion control measures and BMPs, such as placement of 54 silt fences, will be utilized to control erosion and turbidity. Upon completion of clearing/grubbing/grading and elevated 55 boardwalk trail construction, the site will be re -vegetated with native vegetation, which will prevent future erosion from occurring 56 at the site. 57 58 2. Air 59 60 a. What types of emissions to the air would result from the proposal (i.e., dust, automobile, 61 odors, industrial wood smoke) during construction and when the project is completed? If 62 any, generally describe and give approximate quantities if known. 63 64 During construction, there would be internal combustion engine emissions from construction equipment. Most of these short- 6 5 term air quality impacts would be localized and would consist of particulate matter or slight increases in carbon monoxide during 66 the construction phase. 67 68 No long-term increase in air emissions will occur as a result of this project. 69 70 b. Are there any off -site sources of emissions or odor that may affect your proposal? If so, 71 generally describe. 72 73 There are no known sources of emissions or odor that may affect the proposal. 74 75 c. Proposed measures to reduce or control emissions or other impacts to air, if any: 76 77 Minimal air quality impacts are anticipated from the engines of equipment during construction and no long-term impacts 78 are anticipated; therefore, no measures are proposed to reduce or control emissions. 79 80 3. Water 81 82 a. Surface: 83 84 1) Is there any surface water body on or in the immediate vicinity of the site (including 85 year-round and seasonal streams, saltwater, lakes, ponds, wetlands)? If yes, describe type 86 and provide names. If appropriate, state what stream or river it flows into. 87 88 Units A, B, and E are adjacent to Springbrook Creek. Its upstream tributaries, Mill and Garrison Creeks (in 89 Kent), and downstream tributaries, Panther and Rolling Hills Creeks (in Renton), originate on plateaus east of 90 the Green River Valley. The channel of Springbrook Creek is approximately 12 miles long. Downstream of 91 SW 16th Street and I-405, Springbrook Creek enters the improved portion of the creek referred to as the P-1 92 Channel, which flows into the Black River. The Black River empties into the Green/Duwamish River. 93 94 Units A, B, C, and D contain existing wetlands that drain into Springbrook Creek. 95 96 2) Will the project require any work over, in, or adjacent to (within 200 feet) the described 97 waters? If yes, please describe and attach available plans. 98 99 Three berm breaches on Units A and E, and four berm breaches on Unit B will be excavated. The earthen berm is 00 located adjacent to Springbrook Creek. Existing fill material will be removed from Unit E adjacent to Springbrook 01 Creek. An elevated boardwalk trail will be constructed immediately east of Springbrook Creek on Unit A. Reed 02 canarygrass removal and native vegetation planting will occur along the creek banks on Units A, B and E. 03 04 3) Estimate the amount of fill and dredge material that would be placed in or removed 05 from surface water or wetlands and indicate the area of the site that would be affected. 06 Indicate the source of fill material. 07 08 Approximately 110,000 cubic yards of fill on Unit C and 152,000 cubic yards on Unit E will be excavated to re- 0 9 establish former wetlands in those units (Sheets GR3, GR4 and GR6). 10 11 The existing conveyance ditch on Unit C will be plugged with approximately XX cubic yards of clean fill in order to re- 12 direct surface hydrology into the wetland re-establishment areas on Unit C (Sheets GR3 and GR4). In order to install a 13 stormwater pipe to supplement hydrology to Unit D, approximately XX cubic yards of fill will be excavated (Sheet 14 GR5). 15 16 4) Will the proposal require surface water withdrawals or diversions? Give general 17 description, purpose, and approximate quantities if known. 18 19 No natural surface water withdrawals or diversions will occur. However, wetland and floodplain hydrology will be 20 improved as a result of this project. 21 22 Improving the hydrologic regime of existing wetlands (e.g., reconnecting floodplain wetlands on Units A and B to 23 Springbrook Creek, and providing additional hydrology to wetlands on Unit C) will facilitate the rehabilitation of 24 existing wetlands on Units A, B, and C (Table 1). 25 26 Supplemental hydrology will be provided to existing seasonally inundated areas on the northern portion of Unit D 27 (Table 1). The additional water will be redirected from an existing stormwater treatment pond located at the southern 28 end of Unit D via a new conveyance pipe to the northern end of Unit D (Sheet GR5). This additional hydrology will 29 supplement the existing hydrologic regime. 30 31 5) Does the proposal lie within a 100-year floodplain? If so, note location on the site plan. 32 33 Nearly the entire area of Units A and B is located within the 100-year floodplain. The northeastern portion of Unit C is 34 also located within the 100-year floodplain. 35 36 6) Does the proposal involve any discharges of waste materials to surface waters? If so, 37 describe the type of waste and anticipated volume of discharge. 38 39 No. 40 41 b. Ground: 42 43 1) Will ground water be withdrawn, or will water be discharged to ground water? Give 44 general description, purpose, and approximate quantities if known. 45 46 No. 47 48 2) Describe waste material that will be discharged into the ground from septic tanks or 49 other sources, if any (for example: Domestic sewage; industrial, containing the 50 following chemicals... ; agricultural; etc.). Describe the general size of the system, the 51 number of such systems, the number of houses to be served (if applicable), or the number of animals or 52 humans the system(s) are expected to serve. 53 54 No waste material will be discharged into the ground from any source. 55 56 c. Water runoff (including stormwater): 57 58 1) Describe the source of runoff (including storm water) and method of collection 59 and disposal, if any (include quantities, if known). Where will this water flow? 60 Will this water flow into other waters? If so, describe. 61 62 The amount of existing stormwater runoff that enters the site from adjacent roads surrounding properties will 63 remain unchanged. The project will not generate any additional stormwater runoff. . 64 65 2) Could waste materials enter ground or surface waters? If so, generally describe. 66 67 The project will not introduce the potential for waste materials to enter ground or surface waters. 68 6 9 d. Proposed measures to reduce or control surface, ground, and runoff water impacts, if any: 70 71 High visibility temporary construction fencing will be placed around designated work areas to ensure no construction impacts will 72 occur beyond those designated work areas. Additionally, to prevent erosion and impacts to water quality, 73 clearing/grubbing/grading and elevated boardwalk trail construction will only occur during seasonally dry periods. Some 74 temporary erosion could occur during construction activities; however, erosion control measures and BMPs, such as placement of 75 silt fences, will be utilized to control erosion and turbidity. Upon completion of clearing/grubbing/grading and elevated 76 boardwalk trail construction, the site will be re -vegetated with native vegetation, which will prevent future erosion from occurring 77 at the site. Water quality at the Springbrook Bank is expected to improve as a result of the project. 78 79 4. Plants 80 81 a.

(Lead agencies may modify this form to include additional specific information 02 on project description.) 03 04 Background 05 WSDOT and the City of Renton, in partnership, are developing the Springbrook Wetland and Habitat Mitigation Bank 06 (Springbrook Bank) by re-establishing, rehabilitating, enhancing, and preserving 131.54 acres of wetland and riparian area 07 located in the southwest portion of the Renton, Washington. The Springbrook Bank will increase wetland area, hydrologic 08 functions, water quality functions, habitat functions and provide passive environmental education opportunities. 09 2 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 The City of Renton owns the five land parcels (Units A, B, C, D, and E) that comprise the Springbrook Bank. The Springbrook Bank is located in the Lower Green River Basin within Water Resource Inventory Area 9 (WRIA 9), as shown on Sheet V1. The purpose of the Springbrook Bank is to provide compensatory mitigation credits for future unavoidable impacts to wetlands and similar resources caused by WSDOT highway construction projects and other projects permitted by the City of Renton within the service area of the bank. Project Description The proposed project focuses on improving wetland area and function, and riparian functions near Springbrook Creek. Construction work includes extensive site grading on Units C and E; breaching the earthen berms adjacent to Springbrook Creek on Units A, B and E; removal and control of invasive reed canarygrass in Units A, B, and C; constructing an elevated boardwalk trail on Unit A; installing habitat structures; and planting native woody vegetation on all units. This work will enhance a broad range of ecological functions to improve wetland habitat, water quality, and hydrologic functions. Work will be done on the five parcels as follows: Wetland Re -Establishment Areas: Removal of historically placed fill material will allow groundwater and surface water to restore hydrology to former wetlands on Units C and E (Table 1). The excavation in Unit E includes removing sections of an existing earthen berm to connect re-established wetlands on Unit E with Springbrook Creek (Sheet GR6). Native woody plant species and habitat structures (including vertical snags, brush piles, and/or anchored logs) will be installed on Units C and E (Sheets P4 and P6). These activities will restore wetland area, function, and value where wetlands formerly existed. ,(.wi5�'rv�'1^�` Wetland Rehabilitation Areas: Improving the hydrologic regime of existing wetlands (e.g., reohnecting floodplain wetlands on �r�afiti Units A and B to Springbrook Creek, and providing additional hydrology to wetlands on Unit (,will facilitate the rehabilitation , of existing wetlands on Units A, B, and C (Table 1). Microtopography (planting hummocks) will be installed on Units A, B, and C to provide additional habitat niches and hydrologic regimes, as well as facilitate conifer establishment (Sheets P1, P2, P3 and k) P4). Native woody plant species and habitat structures will be installed in Units A, B, and C to improve species diversity and habitat structure and complexity (Sheets P1-4). Wetland Enhancement Type I Areas: Existing wetlands on Unit C will be enhanced by increasing plant and habitat diversity in large areas of invasive non-native vegetation (reed canarygrass and Himalayan blackberry) through a combination of several activities: implementing reed canarygrass removal and control measures; densely planting native trees and shrubs; placing habitat structures; and installing planting hummocks in reed canarygrass removal areas (Sheets P3 and P4). These activities will increase species diversity and habitat structure and complexity. Wetland Enhancement Type II Areas: Supplemental hydrology will be provided to existing seasonally inundated areas on the northern portion of Unit D (Table 1). The additional water will be redirected from an existing stormwater treatment pond located at the southern end of Unit D via a new conveyance pipe to the northern end of Unit D (Sheet GR5). This additional hydrology will supplement the existing hydrologic regime. Forested Wetland Enhancement Areas: Native conifer plant species will be under -planted within the forested wetland portions of Units C and D (Sheets P3, P4, and P5). This will enhance species and structural diversity in both units. Upland Habitat Enhancement Areas: Removing invasive species and installing habitat structures will enhance upland habitat in Units C and E (Sheets P3, P4 and P6). In addition, Unit C will be densely planted with native woody species and Unit E will be under -planted with native conifer plant species in existing deciduous forest areas. Riparian Upland Enhancement Areas: Establishing riparian vegetation through a combination of mowing/herbicide treatment of reed canarygrass, clearing and grubbing other invasive, non-native vegetation, and planting native woody species will enhance riparian function on Units A, B, and E (Table 1, Sheets P1, P2, and P6). Establishing woody species will also provide tree canopy shade for Springbrook Creek. In Unit E, habitat structures will be placed in portions of the enhancement. Protection Setback (Buffer): Portions of all units, except Unit D, will include 40-foot-wide perimeter buffers to be planted with native woody species in both wetlands and uplands. This will promote structural diversity and protect habitat from disturbance from adjacent land uses.

Are there any off -site sources of emissions or odor that may affect your proposal? If so, 71 generally describe. 72 73 There are no known sources of emissions or odor that may affect the proposal. 74 75 c. Proposed measures to reduce or control emissions or other impacts to air, if any: 76 77 Minimal air quality impacts are anticipated from the engines of equipment during construction and no long-term impacts 78 are anticipated; therefore, no measures are proposed to reduce or control emissions. 79 80 3. Water 81 82 a. Surface: 83 84 1) Is there any surface water body on or in the immediate vicinity of the site (including 85 year-round and seasonal streams, saltwater, lakes, ponds, wetlands)? If yes, describe type 86 and provide names. If appropriate, state what stream or river it flows into. 87 88 Units A, B, and E are adjacent to Springbrook Creek. Its upstream tributaries, Mill and Garrison Creeks (in 89 Kent), and downstream tributaries, Panther and Rolling Hills Creeks (in Renton), originate on plateaus east of 90 the Green River Valley. The channel of Springbrook Creek is approximately 12 miles long. Downstream of 91 SW 16th Street and I-405, Springbrook Creek enters the improved portion of the creek referred to as the P-1 92 Channel, which flows into the Black Rive The Blaek Rivefinto Green/Duwamish River. 93 P, �i 94 Units A, B, C, and D contain existing wetlands that drain into Springbrook Creek. rs lalc i2P "*'t ' 95 96 2) Will the project require any work over, in, or adjacent to (within 200 feet) the described 97 waters? If yes, please describe and attach available plans. 98 99 Three berm breaches on Units A aim, and four berm breaches on Unit B will be excavated. The earthen berm is 00 located adjacent to Springbrook Creek. Existing fill material will be removed from Unit E adjacent to Springbrook 01 Creek. An elevated boardwalk trail will be constructed immediately east of Springbrook Creek on Unit A. Reed 02 canarygrass removal and native vegetation planting will occur along the creek banks on Units A, B and E. 03 04 3) Estimate the amount of fill and dredge material that would be placed in or removed 05 from surface water or wetlands and indicate the area of the site that would be affected. 06 Indicate the source of fill material. 07 08 Approximately 110,000 cubic yards of fill on Unit C and 152,000 cubic yards on Unit E will be excavated to re- 0 9 establish former wetlands in those units (Sheets GR3, GR4 and GR6). 10 11 The existing conveyance ditch on Unit C will be plugged with approximately XX cubic yards of clean fill in order to re- 12 direct surface hydrology into the wetland re-establishment areas on Unit C (Sheets GR3 and GR4). In order to install a 13 stormwater pipe to supplement hydrology to Unit D, approximately XX cubic yards of fill will be excavated (Sheet 14 GR5). 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 4) Will the proposal require surface water withdrawals or diversions? Give general description, purpose, and approximate quantities if known. No natural surface water withdrawals or diversions will occur. However, wetland and floodplain hydrology will be improved as a result of this project. Improving the hydrologic regime of existing wetlands (e.g., reconnecting floodplain wetlands on Units A and B to Springbrook Creek, and providing additional hydrology to wetlands on Unit C) will facilitate the rehabilitation of existing wetlands on Units A, B, and C (Table 1). Supplemental hydrology will be provided to existing seasonally inundated areas on the northern portion of Unit D (Table 1). The additional water will be redirected from an existing stormwater treatment pond located at the southern end of Unit D via a new conveyance pipe to the northern end of Unit D (Sheet GR5). This additional hydrology will supplement the existing hydrologic regime. 5) Does the proposal lie within a 100-year floodplain? If so, note location on the site plan. Nearly the entire area of Units A and B is located within the 100-year floodplain. The northeastern portion of Unit C is also located within the 100-year floodplain. 6) Does the proposal involve any discharges of waste materials to surface waters? If so, describe the type of waste and anticipated volume of discharge. No. b. Ground: 1) Will groundwater be withdrawn, or will water be discharged to groundwater? Give general description, purpose, and approximate quantities if known. No. 2) Describe waste material that will be discharged into the ground from septic tanks or other sources, if any (for example: Domestic sewage; industrial, containing the following chemicals... ; agricultural; etc.). Describe the general size of the system, the number of such systems, the number of houses to be served (if applicable), or the number of animals or humans the system(s) are expected to serve. No waste material will be discharged into the ground from any source. c. Water runoff (including stormwater): l) Describe the source of runoff (including storm water) and method of collection and disposal, if any (include quantities, if known). Where will this water flow? Will this water flow into other waters? If so, describe. The amount of existing stormwater runoff that enters the site from adjacent roads surrounding properties will remain unchanged. The project will not generate any additional stormwater runoff. . 2) Could waste materials enter ground or surface waters? If so, generally describe. The project will not introduce the potential for waste materials to enter ground or surface waters. d. Proposed measures to reduce or control surface, ground, and runoff water impacts, if any: High visibility temporary construction fencing will be placed around designated work areas to ensure no construction impacts will occur beyond those designated work areas. Additionally, to prevent erosion and impacts to water quality, 73 clearing/grubbing/grading and elevated boardwalk trail construction will only occur during seasonally dry periods. Some 74 temporary erosion could occur during construction activities; however, erosion control measures and BMPs, such as placement of 75 silt fences, will be utilized to control erosion and turbidity. Upon completion of clearing/grubbing/grading and elevated 76 boardwalk trail construction, the site will be re -vegetated with native vegetation, which will prevent future erosion from occurring 77 at the site. Water quality at the Springbrook Bank is expected to improve as a result of the project. 78 79 4. Plants r ,` 80 81 a.

If WSDOT is doing the SEPA/JARPA for the project, a public notice to property owners within 300 feet is required by SEPA. We can do this but probably not by the end of today. >>> "Hamilton, Brooke" <HamiItB@wsdot.wa.gov> 11/01/05 12:41 PM >>> Hi Ron. I was wondering if you were able to find the property owner information we discussed a need for last Wednesday. A list of the all the property owners that surround the bank units will be at least what I need. If there is a figure w/ the names and location on a map, that would be great too. This is something that needs to be put in the prospectus that will be used for the public notice. Is there anyway I could have this by COB today or first thing in the morning? Thanks.

Receive early coordination letter 6/10/05 1-405 - Springbrook EEI Permitting Strategy Springbrook Creek Wetland and Habitat Mitigation Bank PURPOSE This document describes the permitting approach for local, state, and federal permitting processes to deliver the Springbrook EEI project. OBJECTIVES This document has three main objectives: 1. Identify Key Issues and Assumptions 2. Describe the Springbrook EEI Permit Strategy 3. Identify and Describe Anticipated Permits Objective 1: Key Issues and Assumptions • This project will utilize the Multi -Agency Permit (MAP) Team permit process. • Section 7 Endangered Species Act (ESA) Consultation will be formal. • ESA Consultation must be completed prior to the signing of the Environmental Assessment (EA) for the Renton Nickel project. Currently, the Renton Nickel EA is scheduled to be signed on April 18, 2006. • The EEI ProjectTeam will address and obtain any environmental approvals required for Section 106 of the National Historic Preservation Act (NHPA) to meet the permit schedule. • In coordination with the Springbrook EEI Design Team, the Renton Nickel Design Team will provide permit figures for the DARPA. • Tribal consultations will occur during the NEPA/SEPA process and permitting • ` The Springbrook EEI project assumes the Springbrook Wetland Compensation Bank Mitigation Banking Instrument (MBI) will be approved by the Banking Oversight Committee (BOC) in a timeline that is sufficient to release enough credits to accommodate the permitting needs of the Renton Nickel project. The exact credit needs of the Springbrook EEI project and the exact date of the Springbrook Wetland Compensation Bank completion, and subsequent availability of mitigation credits, is not known at this time. As these details become known, this permit strategy and project schedule will be revised to include these updated details. • The project does not permit geotechnical borings. Geotechnical borings required for preliminary design and environmental documentation will be permitted independently prior to the permitting for the actual Springbrook EEI project. Additional borings prior to construction may also be independently permitted on an as -needed basis. In the event in -water borings are needed, the existing WSDOT programmatic geotechnical boring HPA may be used, provided that the required conditions of that HPA can be met. • WSDOT will be the lead SEPA agency and will utilize the WSDOT SEPA process and policies. C:\DOCLTW—I\aquynn\LOCALS-1\Temp\Springbrook EEI Permit Strategy-draft_v3 - 6_13_05.doc Page 1 of 4 6/10/05 • The Springbrook EEI project does not intend to permit railroad relocations or alterations. • The Springbrook EEI project does not include utility relocation or protection activities. -- - • T e City of Renton will provide the Springbrook EEI team with data that clearly details where the SW 43rd Street undercrossing hydrology is current) Lou to, eluding discharge location(s). ny a i iona wa er quality information regar ing is water should a so be provided. Additionally, if the SW 43rd Street undercrossing was a City of Renton project and a project Biological Assessment (BA) was produced, the City of Renton will provide the Springbrook EEI team with a copy of the approved BA. To meet the ESA schedule, this will be provided to the Springbrook EEI team no later than July 7, 2005. • If the City of Renton has water quality and habitat related data and information #J regarding the Springbrook Creek and its drainage basin, this information will be jl,' provided to the Springbrook EEI team no later than July 7, 2005. �''a� • The City of Renton will provide data, analysis and/or descriptions indicating the wetlands and/or streams that the City of Renton may permit to be altered or filled in exchange for mitigation bank credits. To meet the ESA schedule, will be provided to the Springbrook EEI team no later than July 7, 2005. Objective 2: Describe the Springbrook EEI Permit Strategy Unlike the Renton Nickel project, the Springbrook EEI project will not follow a design - build model. Under the design -build model, permits for the project elements will be based on a 15% design. For the Springbrook EEI project, permits will be based on a 100% design. Similar to the Renton Nickel project, the Springbrook EEI project will work with the Multi Agency Permit (MAP) Team to permit the project. The MAP Team is currently comprised of representatives from the following agencies: Washington Department of Ecology (Ecology), Washington Department of Fish and Wildlife (WDFW), Washington Department of Transportation (WSDOT), United States Army Corps of Engineers (Corps), and King County Department of Development and Environmental Services (DDES). Since the Springbrook EEI project is not located within King County jurisdiction, King County DDES will not be included as a MAP Team participant. Therefore, agencies represented within the MAP Team will include the Washington Department of Ecology (Ecology), Washington Department of Fish and Wildlife (WDFW), Washington Department of Transportation (WSDOT), and the United States Army Corps of Engineers (Corps). The local permitting jurisdiction for the Springbrook EEI project is the city of Renton. It is not anticipated that the city of Renton will participate in the MAP Team process-, however, coordination between Renton permitting staff and the MAP Team may occur at the discretion of the 1-405 Project Environmental Manager. Since the project will not receive federal funding, the Corps will be the NEPA Lead Agency. WSDOT will be the SEPA Lead Agency. SEPA adoption is required before state and local permits can be issued.

Critical areas review will address the adequate protection of aquifer recharge areas, floodplains, geologically hazardous areas, shorelines, streams, wetlands and buffers. • Washington Shoreline Management Act (SMA), Shoreline Substantial Development Permit (SSDP) or SSDP Exemption, RMC 4-3-090 — This will be necessary for proposed work near Springbrook Creek and associated wetlands. Additional Permits or approvals acquired by the Contractor, as needed • Noise Variances — As needed. • ROW construction permit — As needed.

Section 404(b)(1) alternatives analysis will occur as part of the Corps Section 404 permit application review. Washington Department of Ecology • Clean Water Act Section 402 National Pollution Discharge Elimination System Permit (NPDES) — General or Individual — It is anticipated that the Renton Nickel project will also fall under the General Permit. This will be better understood as design information is revealed and MAP Team coordination begins. • Clean Water Act Section 401 Water Quality Certification — Because a Section 404 permit is required, a Section 401 Water Quality Certification (WQC) will be required. At the moment, it is unclear whether this project will require a General or Individual 401 Water Quality Certification. This will be better understood as design information is revealed and MAP Team coordination begins. • Coastal Zone Management Act (CZMA) Consistency Determination — A CZMA Consistency Determination will be required for the Springbrook EEI project. Washington Department of Fish and Wildlife • Hydraulic Project Approval (HPA) — We anticipate that in -water work will be performed and, therefore, an HPA will be required. Coordination on fish habitat design requirements between permitting and design staff will occur early in the design stages so the appropriate considerations can be properly incorporated into the design. Permits or approvals separate from the MAP Team process Washington Department of Natural Resources • Aquatic Use Authorization, if needed. U.S. Fish and Wildlife Service • Endangered Species Act (ESA) Section 7 Consultation and Concurrence — The Springbrook EEI project will actually have confirmed presence of ESA listed species (bull trout, bull trout Critical Habitat, and bald eagle) in the project area. We anticipate going through the formal consultation process.

Identify and Describe Anticipated Permits Objective 1: Key Issues and Assumptions • This project will utilize the Multi -Agency Permit (MAP) Team permit process. • Section 7 Endangered Species Act (ESA) Consultation will be formal. • ESA Consultation must be completed prior to the signing of the Environmental Assessment (EA) for the Renton Nickel project. Currently, the Renton Nickel EA is scheduled to be signed on April 18, 2006. • The EEI Project Team will address and obtain any environmental approvals required for Section 106''of the National Historic Preservation Act (NHPA) to meet the permit schedule. • In coordination with the Springbrook EEI Design Team, the Renton Nickel Design Team will provide permit figutes for the DARPA. • Tribal consultations will occur during the NEPA/SEPA process and permitting Public Notic processes. • The Springbrook EEI pr ect assumes the Springbrook Wetland Compensation Bank Mitigation" Bankiri instrument (MBI) will be approved by the Banking Oversight Committee (BOC) in a timeline that is sufficient to release enough credits to accommodate the permitting needs of the Renton Nickel project. The exact credit needs of the Springbrook EEI project and the exact date of the Springbrook Wetland Compensation Bank completion, and subsequent availability of mitigation credits, is not known at this time. As these details become known, this permit strategy and project schedule will be revised to include these updated details. • The project does not permit geotechnical borings. Geotechnical borings required for preliminary design and environmental documentation will be permitted independently prior to the permitting for the actual Springbrook EEI project. Additional borings prior to construction may also be independently permitted on an as -needed basis. In the event in -water borings are needed, the existing WSDOT programmatic geotechnical boring HPA may be used, provided that the required conditions of that HPA can be met. • WSDOT will be the lead SEPA agency and will utilize the WSDOT SEPA process and policies. C:\DOCUME-1\aquynn\LOCALS-1\Temp\Springbrook EEI Permit Strategy-draft_v3 - 6_13_05.doe Page 1 of 4 6/10/05 • The Springbrook EEI project does not intend to permit railroad relocations or alterations. • The Springbrook EEI project does not include utility relocation or protection activities. • The City of Renton will provide the Springbrook EEI team with data that clearly 5�. details where the SW 43r0 Street undercrossing hydrology is currently routed to, including discharge location(s). Any additional water quality information regarding this water should also be provided. Additionally, if the SW 43rd Street Q undercrossing was a City of Renton project and a project Biological Assessment r/4V4' *4a'L_— (BA) was produced, the City of Renton will provide the Springbrook EEI team with a copy of the approved BA. To meet the ESA schedule, this will be/provided to the Springbrook EEI team no later than July 7, 2005. 2Q,h '1 - 15i rW6'- • If the City of Renton has water quality and habitat related data and information regarding the Springbrook Creek and its drainage basin, this information will be 0"� provided to the Springbrook EEI team no later than July 7, 2005. �q�t}1 ,a • The City of Renton will provide data, analysis and/or descriptions indicating the wetlands and/or streams that the City of Renton may permit to be altered or filled in exchange for mitigation bank credits. To meet the ESA schedule, will be/ provided to the Springbrook EEI team no later than July 7, 2005. ,w, vu(4 be yi v� 1 I � si�+'e+o--v1✓1"��rti Objective 2: Describe the Springbrook EEI Permit Strategy Unlike the Renton Nickel project, the Springbrook EEI project will not follow a design - build model. Under the design -build model, permits for the project elements will be based on a 15% design. For the Springbrook EEI project, permits will be based on a 100% design. Similar to the Renton Nickel project, the Springbrook EEI project will work with the Multi Agency Permit (MAP) Team to permit the project. The MAP Team is currently comprised of representatives from the following agencies: Washington Department of Ecology (Ecology), Washington Department of Fish and Wildlife (WDFW), Washington Department of Transportation (WSDOT), United States Army Corps of Engineers (Corps), and King County Department of Development and Environmental Services (DDES). Since the Springbrook EEI project is not located within King County jurisdiction, King County DDES will not be included as a MAP Team participant. Therefore, agencies represented within the MAP Team will include the Washington Department of Ecology (Ecology), Washington Department of Fish and Wildlife (WDFW), Washington Department of Transportation (WSDOT), and the United States Army Corps of Engineers (Corps). The local permitting jurisdiction for the Springbrook EEI project is the city of Renton. It is not anticipated that the city of Renton will participate in the MAP Team process; however, coordination between Renton permitting staff and the MAP Team may occur at the discretion of the 1-405 Project Environmental Manager. Since the project will not receive federal funding, the Corps will be the NEPA Lead Agency. WSDOT will be the SEPA Lead Agency. SEPA adoption is required before state and local permits can be issued.

Section 404(b)(1) alternatives analysis will occur as part of the Corps Section 404 permit application review. Washington Department of Ecology • Clean Water Act Section 402 National Pollution Discharge Elimination System Permit (NPDES) — General or Individual — It is anticipated that the Renton Nickel project will also fall under the General Permit. This will be better understood as oox�j design information is revealed and MAP Team coordination begins. 0• Clean Water Act Section 401 Water Quality Certification — Because a Section D oa� 404 permit is required, a Section 401 Water Quality Certification (WQC) will be s6p �& Q required. At the moment, it is unclear whether this project will require a General a ) l or Individual 401 Water Quality Certification. This will be better understood as design information is revealed and MAP Team coordination begins. ,7 f • Coastal Zone Management Act (CZMA) Consistency Determination — A CZMA Consistency Determination will be required for the Springbrook EEI project. Washington Department of Fish and Wildlife • Hydraulic Project Approval (HPA) We anticipate that in -water work will be performed and, therefore,: an HPA will be required. Coordination on fish habitat design requirements between permitting and design staff will occur early in the design stages so the appropriate considerations can be properly incorporated into the design. ("- 11 Permits or approvals separate from the MAP Team process Washington Department of Natural Resources • Aquatic Use Authorization, if needed. U.S. Fish and Wildlife Service • Endangered Species Act (ESA) Section 7 Consultation and Concurrence — The Springbrook EEI project will actually have confirmed presence of ESA listed species (bull trout, bull trout Critical Habitat, and bald eagle) in the project area. We anticipate going through the formal consultation process. National Marine Fisheries Service (NMFS) • Endangered Species Act (ESA) Section 7 Consultation and Concurrence — The Springbrook EEI project will actually have confirmed presence of ESA listed C:\DOCUME—I\aquynn\LOCALS—I\Temp\Springbrook EEI Permit Strategy-draft_0 - 6_13_05.doc Page 3 of 4 6/10/05 species (chinook salmon and chinook salmon Critical Habitat) in the project area We anticipate going through the formal consultation process. • Essential Fish Habitat (EFH) Concurrence Permits or approvals from local jurisdictions City of Renton • Washington Growth Management Act (GMA), Critical Areas Ordinance compliance review and approval, RMC 4-3-050 — It is anticipated that we will coordinate Critical Areas review with City of Renton staff to demonstrate project compliance with the substantive requirements of Renton's Critical Areas Ordinance. Critical areas review will address the adequate protection of aquifer recharge areas, floodplains, geologically hazardous areas, shorelines, streams, wetlands and buffers. • Washington Shoreline Management Act (SMA), Shoreline Substantial Development Permit (SSDP) or SSDP Exemption, RMC 4-3-090 — This will be necessary for proposed work near Springbrook Creek and associated wetlands. Additional Permits or approvals acquired by the Contractor, as needed • Noise Variances — As needed. • R-9W construction permit — As needed. u CADOCUME-1\aquynn\LOCALS-1Jemp\Springbrook EEI Permit Strategy-draft_0 - 6_13_05.doc Page 4 of 4 DEVELOPMENT SERVICES DIVISION WAIVER OF SUBMITTAL REQUIREMENTS FOR LAND USE APPLICATIONS . ...... ....................... ............... ...... .......

The proposal will be routed to other City departments and other jurisdictions or agencies who may have an interest in the application. The reviewers have two weeks to return their comments to the Development Services Division. Within approximately two weeks, the Development Services Division will prepare a report regarding the proposal's compliance with applicable codes and the City's review criteria. The proposal will then be presented to the City's Environmental Review Committee. The Environmental Review Committee is comprised of the Administrator of the Planning/Building/Public Works Department, the Administrator of Community Services, and the Fire Chief. The Committee is responsible for determining whether the proposal will result in significant adverse environmental impacts. To do this, the committee will consider such issues as environmental health hazards, wetlands, groundwater, energy and natural resources and will then issue its decision (Environmental Threshold Determination). The Environmental Review Committee will either issue a: Determination of Non -Significance (DNS) -Make a determination the proposal will have no significant negative environmental impacts or; Mitigated Determination of Non -Significance (DNS-M)-Make a determination the proposal, if modified, would have no significant negative environmental impacts or; Determination of Significance (DS)-Make a determination the proposal will have significant adverse environmental impacts and require the applicant to submit an Environmental Impact Statement (EIS) prepared by a qualified consultant Once the Environmental Review Committee has issued its Environmental Threshold Determination (provided an EIS is not required), a public notice of the Determination is printed in the South County Journal and three notices are posted at or near the site. A 14-day appeal period commences following the publication date. At the discretion of the City, a separate and additional 15-day comment period may be added prior to the 14-day appeal period. APPEAL AND RECONSIDERATION PROCESS FOR DECISIONS: Any person, including the applicant, aggrieved by the threshold determination, may make a written application for reconsideration to the Environmental Review Committee within 14 calendar days of the date of the decision. After review of the request, the Environmental Review Committee may take whatever action is deemed proper. The Environmental Review Committee decision on the reconsideration request will be mailed to all parties of record within 10 days from the date the request was filed. If any party is still not satisfied after a reconsideration decision has been issued, an appeal may be submitted within 14 days to the Hearing Examiner. An appeal may be filed without requesting reconsideration by the Reviewing Official first, however, it must be filed within 14 days of the date when the original decision was issued. See Renton Municipal Code, Section 4-8-110 for further information on the appeal process and time frames. Q:\WEB\PW\DEVSERV\Forms\Planning\envrev.doc BUILDING AND CONSTRUCTION PERMIT ISSUANCE AND INSTALLATION OF IMPROVEMENTS: In the City of Renton, a Building Permit must be obtained to build buildings and structures. A Construction Permit must be obtained to install utility lines, transportation improvements and undertake work in City right-of-ways. Building and Construction Permits are separate permits. Applicants may apply for building and construction permits concurrently with their request for a land use application. However, the applicant should be aware any conditions of land use permit approval may create a need for revisions to other permit applications whereby additional fees may be charged. Refunds of building permit charges are not available. If no appeals or reconsideration requests are filed within 14 days of the effective date of the decision to approve the application, the applicant may obtain building and construction permits. A construction permit for the installation of on -site and off -site utilities will be issued upon the review and approval of civil engineering drawings by the Division's Public Works Section and receipt of all applicable development and permit fees. A building permit will be issued upon the Building Section's approval of building plans and receipt of all applicable fees. DEFERRAL OF IMPROVEMENTS: If a developer wishes to defer certain on -site or off -site improvements (i.e. landscaping, curbs and sidewalks), written application with full and complete engineering drawings must be submitted to the Development Services Division. The application should explain the reasons why such delay is necessary. If approval is granted, security in the form of an irrevocable letter of credit, set -aside fund, assignment of funds, certified check or other type of security acceptable to the City shall be furnished to the City in an amount equal to a minimum of 150% of the estimated cost of the required improvements.

An Environmental Impact Statement (EIS) must be prepared for all proposals with probable significant adverse impacts on the quality of the environment. The purpose of this checklist is to provide information to help you and the agency identify impacts from your proposal (and to reduce or avoid impacts from the proposal, if it can be done) and to help the agency decide whether an EIS is required. INSTRUCTIONS FOR APPLICANTS: This environmental checklist asks you to describe some basic information about your proposal. Governmental agencies use this checklist to determine whether the environmental impacts of your proposal are significant, requiring preparation of an EIS. Answer the questions briefly, with the most precise information known, or give the best description you can. You must answer each question accurately and carefully, to the best of your knowledge. In most cases, you should be able to answer the questions from your own observations or project plans without the need to hire experts. If you really do not know the answer, or if a question does not apply to your proposal, write "do not know" or "does not apply". Complete answers to the questions now may avoid unnecessary delays later. Some questions ask about governmental regulations, such as zoning, shoreline, and landmark designations. Answer these questions if you can. If you have problems, the governmental agencies can assist you. The checklist questions apply to all parts of your proposal, even if you plan to do them over a period of time or on different parcels of land. Attach any additional information that will help describe your proposal or its environmental effects. The agency to which you submit this checklist may ask you to explain your answers or provide additional information reasonably related to determining if there may be significant adverse impact. USE OF CHECKLIST FOR NONPROJECT PROPOSALS: Complete this checklist for nonproject proposals, even though questions may be answered "does not apply." IN ADDITION, complete the SUPPLEMENTAL SHEET FOR NONPROJECT ACTIONS (part D). For nonproject actions (actions involving decisions on policies, plans and programs), the references in the checklist to the words "project," "applicant," and "property or site" should be read as "proposal," "proposer," and "affected geographic area," respectively.

An Environmental Impact Statement (EIS) must be prepared for all proposals with probable significant adverse impacts on the quality of the environment. The purpose of this checklist is to provide information to help you and the agency identify impacts from your proposal (and to reduce or avoid impacts from the proposal, if it can be done) and to help the agency decide whether an EIS is required. INSTRUCTIONS FOR APPLICANTS: This environmental checklist asks you to describe some basic information about your proposal. Governmental agencies use this checklist to determine whether the environmental impacts of your proposal are significant, requiring preparation of an EIS. Answer the questions briefly, with the most precise information known, or give the best description you can. You must answer each question accurately and carefully, to the best of your knowledge. In most cases, you should be able to answer the questions from your own observations or project plans without the need to hire experts. If you really do not know the answer, or if a question does not apply to your proposal, write "do not know" or "does not apply". Complete answers to the questions now may avoid unnecessary delays later. Some questions ask about governmental regulations, such as zoning, shoreline, and landmark designations. Answer these questions if you can. If you have problems, the governmental agencies can assist you. The checklist questions apply to all parts of your proposal, even if you plan to do them over a period of time or on different parcels of land. Attach any additional information that will help describe your proposal or its environmental effects. The agency to which you submit this checklist may ask you to explain your answers or provide additional information reasonably related to determining if there may be significant adverse impact. USE OF CHECKLIST FOR NONPROJECT PROPOSALS: Complete this checklist for nonproject proposals, even though questions may be answered "does not apply." IN ADDITION, complete the SUPPLEMENTAL SHEET FOR NONPROJECT ACTIONS (part D). For nonproject actions (actions involving decisions on policies, plans and programs), the references in the checklist to the words "project," "applicant," and "property or site" should be read as "proposal," "proposer," and "affected geographic area," respectively.

Give brief, complete description of your proposal, including the proposed uses and the size of the project and site. There are several questions later in this checklist that ask you to describe certain aspects of your proposal. You do not need to repeat those answers on this page. (Lead agencies may modify this form to include additional specific information on project description.) Background WSDOT and the City of Renton, in partnership, are developing the Springbrook Wetland and Habitat Mitigation Bank (Springbrook Bank) by re-establishing, rehabilitating, enhancing, and preserving 131.54 acres of wetland and riparian area located in the southwest portion of the Renton, Washington. The Springbrook Bank will increase wetland area, hydrologic functions, water quality functions, habitat functions and provide passive environmental education opportunities. 10 The City of Renton owns the five land parcels (Units A, B, C, D, and E) that comprise the Springbrook Bank. The Springbrook 11 Bank is located in the Lower Green River Basin within Water Resource Inventory Area 9 (WRIA 9), as shown on Sheet V I. The 12 purpose of the Springbrook Bank is to provide compensatory mitigation in advance of unavoidable impacts to wetlands and other 13 aquatic resources from future projects within portions of the Cedar-Sammamish Watershed (WRIA. 8) and Green-Duwamish 14 Watershed (WRIA 9). Project Description The proposed project focuses on improving wetland area and function, and riparian functions near Springbrook Creek. Construction work includes extensive site grading on Units C and E; breaching the earthen berms adjacent to Springbrook Creek on Units A, B and E; removal and control of invasive reed canarygrass in Units A, B, and C; constructing an elevated boardwalk trail on Unit A; installing habitat structures; and planting native woody vegetation on all units. This work will enhance a broad range of ecological functions to improve wetland habitat, water quality, and hydrologic functions. Work will be done on the five parcels as follows: Wetland Re -Establishment Areas: Removal of historically placed fill material will allow groundwater and surface water to restore hydrology to former wetlands on Units C and E (Table 1). The excavation in Unit E includes removing sections of an existing earthen berm to connect re-established wetlands on Unit E with Springbrook Creek (Sheet GR6). Native woody plant species and habitat structures (including vertical snags, brush piles, and/or logs) will be installed on Units C and E (Sheets P4 and P6). These activities will restore wetland area, function, and value where wetlands formerly existed. Wetland Rehabilitation Areas: Improving the hydrologic regime of existing wetlands (e.g., reconnecting floodplain wetlands on Units A and B to Springbrook Creek, and providing additional hydrology to wetlands on Unit C by constructing log weir and redirecting flows from an existing stormwater pond upstream of Unit Okwill facilitate the rehabilitation of existing wetlands on Units A, B, and C (Table 1). Microtopography (planting hummocks) vAlf be installed on Units A, B, and C to provide additional habitat niches and hydrologic regimes, as well as facilitate conifer establishment (Sheets P1, P2, P3 and P4). Native woody plant species and habitat structures will be installed in Units A, B, and C to improve species diversity and habitat structure and complexity (Sheets P1 4). 39 Wetland Enhancement Type I Areas: Existing wetlands on Unit C will be enhanced by increasing; plant and habitat diversity in 40 large areas of invasive non-native vegetation (reed canarygrass and Himalayan blackberry) through a combination of several 41 activities: implementing reed canarygrass removal and control measures; densely planting native trees and shrubs; placing habitat 42 structures; and installing planting hummocks in reed canarygrass removal areas (Sheets P3 and P4). These activities will increase 43 species diversity and habitat structure and complexity. 44 45 Wetland Enhancement Type II Areas: Supplemental hydrology will be provided to existing seasonally inundated areas on the 46 northern portion of Unit D (Table 1). The additional water will be redirected from an existing storm water treatment pond located 47 at the southern end of Unit D via a new conveyance pipe to the northern end of Unit D (Sheet GR5) This additional hydrology 48 will supplement the existing hydrologic regime. 49 50 Forested Wetland Enhancement Areas: Native conifer plant species will be under -planted within the forested wetland portions 51 of Units C and D (Sheets P3, P4, and P5). This will enhance species and structural diversity in both units. 52 53 Upland Habitat Enhancement Areas: Removing invasive species and installing habitat structures will enhance upland habitat in 54 Units C and E (Sheets P3, P4 and P6). In addition, Unit C will be densely planted with native woody species and Unit E will be 55 under -planted with native conifer plant species in existing deciduous forest areas. 56 57 Riparian Upland Enhancement Areas: Establishing riparian vegetation through a combination of mowing/herbicide treatment 58 of reed canarygrass, clearing and grubbing other invasive, non-native vegetation, and planting native woody species will enhance 59 riparian function on Units A, B, and E (Table 1, Sheets P 1, P2, and P6). Establishing woody species will also provide tree canopy 60 shade for Springbrook Creek. In Unit E, habitat structures will be placed in portions of the enhancement. 61 62 Protection Setback (Buffer): Portions of all units, except Unit D, will include 40-foot-wide perime:er buffers to be planted with 63 native woody species in both wetlands and uplands. This will promote structural diversity and protect habitat from disturbance 64 from adjacent land uses. 65 66 Table 1 provides a summary of treatment types and acreage amounts for the Springbrook Creek Bari. 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 Table 1 Habitat Treatment Type and Acreage Summary Acreage I--.._..- - . - _..... . _..... __ ................. ............................... ............................................ ;_._............ _............ _...... .._........... --_.... .........

Unit E is a 15.22 acre undeveloped piece of property located south of SW 34th Street, west and adjacent to Springbrook Creek, north of SW 41 st Street, and east of Oakesdale Avenue SW. It is bordered to the north by developed light industrial zoned land. 4 01 B. ENVIRONMENTAL ELEMENTS 02 03 1. Earth 04 05 a. General description of the site (circle one): FFlaJ, rolling, hilly, steep slopes, mountainous, 06 other...... 07 08 b. What is the steepest slope on the site (approximate percent slope)? 09 10 The Springbrook Bank is located within the nearly flat Green River Valley. Existing slope areas at the Springbrook 11 Bank site include the sides of the earthen berms adjacent to Springbrook Creek on Units A, B, and E and the roadway 12 slopes adjacent to Units A and B. These slopes may range from 1 percent to approximately 40 percent. The steepest 13 berm slopes are located on Site E. 14 15 c. What general types of soils are found on the site (for example, clay, sand, gravel, peat, 16 muck)? If you know the classification of agricultural soils, specify them and note any prime 17 farmland. 18 19 The King County Soil Survey describes four soil types at the Springbrook Bank site: Puget silty clay loam, Puyallup fine sandy 20 loam, Snohomish silt loam, and Woodinville silt loam. 21 22 d. Are there surface indications or history of unstable soils in the immediate vicinity? If so, 23 describe. 24 25 The City of Renton Critical Areas Ordinance maps indicate that all five parcels lie within a seismic hazard area. 26 27 e. Describe the purpose, type, and approximate quantities of any filling or grading proposed. 28 Indicate source of fill. 29 30 Approximately 583 cubic yards of previously placed fill material will be excavated and removed to breach the berms in Units A 31 and B (Sheets GRl and 2). Approximately 100,000 cubic yards of previously placed fill material in Unit C and 160,000 cubic 32 yards in Unit E will be excavated and removed to re-establish former wetlands in those units (Sheets GR3, GR4 and GR6). In 33 order to install a stormwater pipe to supplement hydrology to Unit D, approximately 20 cubic yards of fill will be excavated and 34 removed (Sheet GR5). 35 36 The existing conveyance ditch in Unit C will be plugged with approximately 67 cubic yards of clean fill in order to redirect 37 surface hydrology into the wetland re-establishment area on Unit C (Sheets GR3 and GR4). 38 39 f. Could erosion occur as a result of clearing, construction, or use? If so, generally describe. 40 41 Some temporary erosion could occur during construction activities; however, erosion control measures and best management 42 practices (BMPs), such as placement of silt fences and compost berms, will be utilized to control erosion and turbidity. Upon 43 completion of clearing/grubbing /grading and elevated boardwalk trail construction, the site will be re -vegetated with native 44 vegetation, which will prevent future erosion from occurring at the site. 45 46 g. About what percent of the site will be covered with impervious surfaces after project 47 construction (for example, asphalt or buildings)? 48 49 None. 50 51 h. Proposed measures to reduce or control erosion, or other impacts to the earth, if any: 52 53 High visibility temporary construction fencing will be placed around designated work areas to ensure no construction impacts will 54 occur beyond those designated work areas. Additionally, to prevent erosion and impacts to water quality, 55 clearing/grubbing/grading and elevated boardwalk trail construction will only occur during seasonally dry periods. Some 56 temporary erosion could occur during construction activities; however, erosion control measures and BMPs, such as placement of 57 silt fences and compost berms, will be utilized to control erosion and turbidity. Upon completion of clearing/grubbing/grading 58 and elevated boardwalk trail construction, the site will be re -vegetated with native vegetation, which will prevent future erosion 59 from occurring at the site. 60 61 2. Air 62 63 a. What types of emissions to the air would result from the proposal (i.e., dust, automobile, 64 odors, industrial wood smoke) during construction and when the project is completed? If 65 any, generally describe and give approximate quantities if known. 66 67 During construction, there would be internal combustion engine emissions from construction equipment. Most of these short- 6 8 term air quality impacts would be localized and would consist of particulate matter or slight increases in carbon monoxide during 69 the construction phase. 70 71 No long-term increase in air emissions will occur as a result of this project. 72 73 b. Are there any off -site sources of emissions or odor that may affect your proposal? If so, 74 generally describe. 75 76 There are no known sources of emissions or odor that may affect the proposal. 77 78 c. Proposed measures to reduce or control emissions or other impacts to air, if any: 79 80 Minimal air quality impacts are anticipated from the engines of equipment during construction and no long-term impacts 81 are anticipated; therefore, no measures are proposed to reduce or control emissions. 82 83 3. Water 84 85 a. Surface: 86 87 1) Is there any surface water body on or in the immediate vicinity of the site (including 88 year-round and seasonal streams, saltwater, lakes, ponds, wetlands)? If yes, describe type 89 and provide names. If appropriate, state what stream or river it flows into. 90 91 Units A, B, and E are adjacent to Springbrook Creek. Its upstream tributaries, Mill and Garrison Creeks (in 92 Kent), and downstream tributaries, Panther and Rolling Hills Creeks (in Renton), originate on plateaus east of 93 the Green River Valley. The channel of Springbrook Creek is approximately 12 miles long. Downstream of 94 SW 16th Street and 1405, Springbrook Creek enters the improved portion of the creek referred to as the P-1 95 Channel, which flows into the Black River Forebay and is pumped into the Green/Duwamish River via the 96 King County owned and operated Black River Pump Station. 97 98 Units A, B, C, and D contain existing wetlands that drain into Springbrook Creek. 99 00 2) Will the project require any work over, in, or adjacent to (within 200 feet) the described 01 waters? If yes, please describe and attach available plans. 02 03 Three berm breaches each on Units A and E, and four berm breaches on Unit B will be excavated. The earthen berm is 04 located adjacent to Springbrook Creek. Existing fill material will be removed from Unit E adjacent to Springbrook 05 Creek. An elevated boardwalk trail will be constructed immediately east of Springbrook Creek on Unit A. Reed 06 canarygrass removal and native vegetation planting will occur along the creek banks on Units A, B and E. 07 08 3) Estimate the amount of fill and dredge material that would be placed in or removed 09 from surface water or wetlands and indicate the area of the site that would be affected. 10 Indicate the source of fill material. 11 12 Approximately 100,000 cubic yards of fill on Unit C and 160,000 cubic yards on Unit E will be excavated to re- 13 establish former wetlands in those units (Sheets GR3, GR4, and GR6). 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 The existing conveyance ditch on Unit C will be plugged with approximately 67 cubic yards of clean fill in order to re- direct surface hydrology into the wetland re-establishment areas on Unit C (Sheets GR3 and GR4). In order to install a stormwater pipe to supplement hydrology to Unit D, approximately 20 cubic yards of fill will be excavated (Sheet GR5). 4) Will the proposal require surface water withdrawals or diversions? Give general description, purpose, and approximate quantities if known. No natural surface water withdrawals or diversions will occur. However, wetland and floodplain hydrology will be improved as a result of this project. Breaching of berms will not divert surface water during normal flow conditions. High flows are currently impounded within the flood control berms along Springbrook Creek. After breaching, these high flows will spread out over the natural floodplain. Improving the hydrologic regime of existing wetlands (e.g., reconnecting floodplain wetlands on Units A and B to Springbrook Creek, and providing additional hydrology to wetlands on Unit C) will facilitate the rehabilitation of existing wetlands on Units A, B, and C (Table 1). Supplemental hydrology will be provided to existing seasonally inundated areas on the northern portion of Unit D (Table 1). The additional water will be redirected from an existing stormwater treatment pond located at the southern end of Unit D via a new conveyance pipe to the northern end of Unit D (Sheet GR5). This additional hydrology will supplement the existing hydrologic regime. The water from the treatment pond is currently piped to the municipal stormwater system, which eventually empties into Springbrook Creek near Site E. Following construction, the water will reach Springbrook Creek by flowing through the wetland. 5) Does the proposal lie within a 100-year floodplain? If so, note location on the site plan. Nearly the entire area of Units A and B is located within the 100-year floodplain. The northeastern portion of Unit C is also located within the 100-year floodplain. 6) Does the proposal involve any discharges of waste materials to surface waters? If so, describe the type of waste and anticipated volume of discharge. No. b. Ground: 1) Will groundwater be withdrawn, or will water be discharged to groundwater? Give general description, purpose, and approximate quantities if known. No. 2) Describe waste material that will be discharged into the ground from septic tanks or other sources, if any (for example: Domestic sewage; industrial, containing the following chemicals... ; agricultural; etc.). Describe the general size of the system, the number of such systems, the number of houses to be served (if applicable), or the number of animals or humans the system(s) are expected to serve. No waste material will be discharged into the ground from any source. c. Water runoff (including stormwater): 1) Describe the source of runoff (including storm water) and method of collection and disposal, if any (include quantities, if known). Where will this water flow? Will this water flow into other waters? If so, describe. A temporary construction entrance and tire wash area will be installed at the northwest corner of Unit A, the northeast corner of Unit B, the east end of Unit C, the southeast corner of Unit D, and the northwest corner of Unit E. The tire 71 wash water will be discharged to a Baker tank and then either hauled off -site or discharged into a sanitary sewer. The 72 exact method of removal will be determined by the contractor. 73 74 2) Could waste materials enter ground or surface waters? If so, generally describe. 75 76 The project will not introduce the potential for waste materials to enter ground or surface waters. 77 78 d. Proposed measures to reduce or control surface, ground, and runoff water impacts, if any: 79 80 High visibility temporary construction fencing will be placed around designated work areas to ensure no construction impacts will 81 occur beyond those designated work areas. Street sweeping activities may be required to control soil that gets tracked onto 82 adjacent roadways from construction equipment. Additionally, to prevent erosion and impacts to water quality, 83 clearing/grubbing/grading and elevated boardwalk trail construction will only occur during seasonally dry periods. Some 84 temporary erosion could occur during construction activities; however, erosion control measures and BMPs, such as placement of 85 silt fences, will be utilized to control erosion and turbidity. Upon completion of clearing/grubbing/grading and elevated 86 boardwalk trail construction, the site will be re -vegetated with native vegetation, which will prevent future erosion from occurring 87 at the site. Water quality at the Springbrook Bank is expected to improve as a result of the project. 88 89 4. Plants 90 91 a. Check or circle types of vegetation found on the site: ,maple, aspen, the cottonwood, willow 92 X deciduous tree: aide 93 evergreen tree: fir, cedar, pine, other 94 X shrubs Himalayan blackberry, red -osier dogwood, Scot's broom 95 X grass bentgrasses, orchard grass, ryegrass 96 pasture 97 crop or grain 98 X wet soil plants: attai buttercu , bullrush, skunk cabbage, the :reed canarygrass, bittersweet 99 nightshade, scouring rush, yellowflag iris, waterpepper, stinging nettle 00 water plants: water lily, eelgrass, milfoil, other 01 X other types of vegetation: English ivy, hedge bindweed, tansy, teasel, thistle 02 03 b. What kind and amount of vegetation will be removed or altered? 04 05 A large amount of reed canarygrass and Himalayan Blackberry will be removed and controlled by mowing and spraying. 06 Himalayan blackberry and other invasive species present within the buffer will be cleared and grubbed in preparation for the 07 planting of native woody species. Himalayan blackberry will be cleared in some places to allow access for berm breaching. 08 Clearing and grubbing are required to create construction access entrances and routes (Sheet SP 1-SP6). Portions of Units C, D, 09 and E will be cleared in the process of fill removal and a portion of Unit A will be cleared for the construction of the elevated 10 boardwalk trail (Sheets SP1-SP6). 11 12 c. List threatened or endangered species known to be on or near the site. 13 14 Marsh sandwort and golden paintbrush appear on the USFWS species list as likely to occur, but have not been found to occur at 15 the site. 16 17 d. Proposed landscaping, use of native plants, or other measures to preserve or enhance 18 vegetation on the site, if any: 19 20 Native woody vegetation will be planted in reed canarygrass removal areas to discourage recurrence of invasive reed canarygrass. 21 Areas surrounding the berm breaches in Units A, B, and E will be densely planted with native trees and shrubs to provide tree 22 canopy shade for Springbrook Creek (Sheets P 1-P6). Recently excavated surface areas will receive a minimum of 3 inches of 23 organic compost material. All disturbed soils will be covered with a minimum of 3 inches of woody mulch to deter reed 24 canarygrass growth and promote native woody plant establishment. Disturbed soil areas near Springbrook Creek will be 25 protected with coir or jute fabric to prevent erosion. Efforts will be made to preserve as much existing native vegetation on site as 26 possible. 27 28 Selection of native vegetation species was based on native species known to occur in the project area that will provide cover, 29 tolerance of flood conditions, value to wildlife, and likelihood of success. Tree plantings will include 24- to 36-inch bare root, 1- 3 0 gallon containers, or live stakes. Shrub plantings will include 24- to 36-inch bare root or live stakes.

If applicable, what is the current shoreline master program designation of the site? 49 50 The section of Springbrook Creek adjacent to the Springbrook Bank site designated as a shoreline of the state. The Springbrook 51 Creek shoreline zone, which is designated as Urban Environment, extends 200 feet landward from the creek's ordinary high water 52 mark (OHWM). All adjacent wetlands associated with Springbrook Creek are also regulated shorelines and are designated as 53 Conservancy Environment. The wetlands on Units A, B and C are all regulated as shorelines. 54 55 h. Has any part of the site been classified as an "environmentally sensitive" area? If so, specify. 56 57 Units A, B, C, and D contain existing wetlands, shown on Sheet Tl . All five site units lie within a seismic hazard zone, as shown 58 on the City of Renton's Critical Areas map. 59 60 i. Approximately how many people would reside or work in the completed project? 61 62 None. j. Approximately how many people would the completed project displace? None. k. Proposed measures to avoid or reduce displacement impacts, if any: None. 1. Proposed measures to ensure the proposal is compatible with existing and projected land uses and plans, if any: The City of Renton will review the project during the Shoreline Substantial Development permitting process. 9. Housing a. Approximately how many units would be provided, if any? Indicate whether high, mid- dle, or low-income housing. None. b. Approximately how many units, if any, would be eliminated? Indicate whether high, middle, or low-income housing. None. c. Proposed measures to reduce or control housing impacts, if any: No measures are proposed because no impacts are anticipated. 10. Aesthetics a. What is the tallest height of any proposed structure(s), not including antennas; what is the principal exterior building material(s) proposed? No building structures are proposed. Vertical habitat snags up to 30 feet high will be installed throughout the five units. The elevated boardwalk trail structure will reach a maximum height of 9 feet. Within a few growing seasons after construction, it is expected that the boardwalk structure elevation will be exceeded by the height of the surrounding native vegetation. b. What views in the immediate vicinity would be altered or obstructed? Vicinity views will not be obstructed by the project. c. Proposed measures to reduce or control aesthetic impacts, if any: The native vegetation plantings are expected to be more aesthetically pleasing than the current degraded wetlands. A raised boardwalk will allow public enjoyment and passive environmental education, while protecting soils and vegetation from the impacts of foot traffic. 11. Light and glare a. What type of light or glare will the proposal produce? What time of day would it mainly occur? No light or glare will be produced. The elevated boardwalk trail will not contain lights and the construction materials used will not produce light glare. 12 20 b. Could light or glare from the finished project be a safety hazard or interfere with views? 21 22 No light or glare will be produced from the finished project. 23 24 c. What existing off -site sources of light or glare may affect your proposal? 25 26 None. 27 28 d. Proposed measures to reduce or control light and glare impacts, if any: 29 30 No measures are proposed because no impacts are anticipated. 31 32 12. Recreation 33 34 a. What designated and informal recreational opportunities are in the immediate vicinity? 35 36 Bicycle lanes exist on Oakesdale Avenue SW. The road is heavily used by bicyclists traveling between Renton and popular 37 cycling roads in the Puyallup Valley. 38 39 The City of Renton's Springbrook Trail and King County's Interurban Trail and Green River Trail serve this area. The proposed 40 boardwalk through Unit A is a missing link in the Springbrook Trail system. Completing this missing link will help in connecting 41 the Springbrook Trail to the Interurban and Green River Trails. Interpretive signs along the boardwalk will provide passive 42 environmental education opportunities. The boardwalk will also furnish passive recreational opportunities for wildlife viewing 43 and bird watching. The elevated boardwalk trail on Unit A will only allow foot traffic. 44 45 b. Would the proposed project displace any existing recreational uses? If so, describe. No existing legal recreational uses will be displaced. c. Proposed measures to reduce or control impacts on recreation, including recreation opportunities to be provided by the project or applicant, if any: The boardwalk will protect the surrounding area from impacts due to foot traffic in the wetlands. 13. Historic and cultural preservation a. Are there any places or objects listed on, or proposed for, national, state, or local preservation registers known to be on or next to the site? If so, generally describe. No historical or cultural resources are known to be on or near the site. 61 b. Generally describe any landmarks or evidence of historic, archaeological, scientific, or 62 cultural importance known to be on or next to the site. 63 64 No landmarks or evidence of such resources are known to be on or near the site. 65 66 c.

The site units are also bordered by Lind Avenue SW and SW 76 27th, 34th, 41 st, and 43rd Streets. 13 77 78 b. Is site currently served by public transit? If not, what is the approximate distance to the 79 nearest transit stop? 80 81 King County Metro Routes 153, 163, and 247 currently serve the area near the site. The nearest stop is at SW 27th Street and 82 Lind Avenue SW. 83 84 c. How many parking spaces would the completed project have? How many would the 85 project eliminate? 86 87 No parking spaces are proposed and none will be eliminated. 88 89 d. Will the proposal require any new roads or streets, or improvements to existing roads or 90 streets, not including driveways? If so, generally describe (indicate whether public or 91 private). 92 93 No. 94 95 e. Will the project use (or occur in the immediate vicinity of) water, rail, or air transporta- 9 6 tion? If so, generally describe. 97 98 No. 99 00 f. How many vehicular trips per day would be generated by the completed project? If known, indicate when 01 peak volumes would occur. 02 03 A very small number of vehicular trips, if any, will be generated by the completed project. 04 05 g. Proposed measures to reduce or control transportation impacts, if any: 06 07 Truck traffic generated during excavation hauling may produce short-term impacts to transportation. WSDOT and the City of 08 Renton are currently developing a haul route and plan in order to control impacts. This plan will include hours of hauling (to 09 avoid peak traffic times), haul routes (to avoid impacts to traffic and to infrastructure), and traffic control plans (to provide safe 10 access to the sites). 11 12 15. Public services 13 14 a. Would the project result in an increased need for public services (for example: fire protection, police 15 protection, health care, schools, other)? If so, generally describe. 16 17 No additional public services will be needed as a result of the project. 18 19 b. Proposed measures to reduce or control direct impacts on public services, if any. 20 21 None. 22 23 16. Utilities 24 25 a. Circle utilities currently available at the site: electricity, natural gas, water, refuse service, telephone, sanitary 26 sewer, septic system, other. 27 28 Utility easements exist around the perimeter of all the units in areas adjacent to roadways. In addition, there are utility easements 29 across Units D and E. 30 31 b. Describe the utilities that are proposed for the project, the utility providing the service, 32 and the general construction activities on the site or in the immediate vicinity which might 33 be needed. 14 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 No new utilities are proposed to support construction. Construction equipment will be powered by internal combustion engines A stormwater pipe will be installed to convey stormwater from the existing treatment pond at the southern end of Unit D to the northern end of Unit D, where it will outfall to enhance existing wetland hydrology. To ensure the survival of the plantings at the site, 1-inch-diameter PVC pipes with sprinkler heads will be laid above ground through planted areas. These pipes will be connected to the existing municipal water system and will operate on a timer system. This sprinkler network will be left in place until plants are established at the site, probably 2 to 3 years. C. SIGNATURE The above answers are true and complete to the best of my knowledge.
