Washington State Department of Labor and Industries Policy Statement (Regarding the Production of "Standard" or "Non-standard" Items) Below is the department's (State L&I's) list of criteria to be used in determining whether a prefabricated item is "standard" or "non-standard". For items not appearing on WSDOT's predetermined list, these criteria shall be used by the Contractor (and the Contractor's subcontractors, agents to subcontractors, suppliers, manufacturers, and fabricators) to determine coverage under RCW 39.12. The production, in the State of Washington, of non-standard items is covered by RCW 39.12, and the production of standard items is not. The production of any item outside the State of Washington is not covered by RCW 39.12. 1. Is the item fabricated for a public works project? If not, it is not subject to RCW 39.12. If it is, go to question 2. 2. Is the item fabricated on the public works jobsite? If it is, the work is covered under RCW 39.12. If not, go to question 3. 3. Is the item fabricated in an assembly/fabrication plant set up for, and dedicated primarily to, the public works project? If it is, the work is covered by RCW 39.12. If not, go to question 4. 4. Does the item require any assembly, cutting, modification or other fabrication by the supplier? If not, the work is not covered by RCW 39.12. If yes, go to question 5. 5. Is the prefabricated item intended for the public works project typically an inventory item which could reasonably be sold on the general market? If not, the work is covered by RCW 39.12. If yes, go to question 6. 6. Does the specific prefabricated item, generally defined as standard, have any unusual characteristics such as shape, type of material, strength requirements, finish, etc? If yes, the work is covered under RCW 39.12. Any firm with questions regarding the policy, WSDOT's Predetermined List, or for determinations of covered and non-covered workers shall be directed to State L&I at (360) 902-5330.

(See Definitions in the Construction Stormwater General Permit).* http://www.ecy.wa.gov/programs/wq/stormwater/construction/contacts.html *Note that if you receive permit coverage without indicating the preference for a demonstrably equivalent BMP and later decide to use one, you must provide Ecology with notice of the selection of an equivalent BMP no less than 60 days before the intended use of the equivalent BMP.

IX. Discharge/Receiving Water Information Indicate whether your site’s stormwater and/or dewatering water could enter surface waters, directly and/or indirectly: Water will discharge directly or indirectly (through a storm drain system or roadside ditch) into one or more surface waterbodies (wetlands, creeks, lakes, and all other surface waters and water courses). If your discharge is to a storm sewer system, provide the name of the operator of the storm sewer system: (e.g., City of Tacoma): City of Redmond (NOTE: If your stormwater discharges to a storm sewer system operated by the City of Seattle, King County, Snohomish County, City of Tacoma, Pierce County, or Clark County, you must also submit a copy of this NOI to the appropriate jurisdiction.) Water will discharge to ground with 100% infiltration, with no potential to reach surface waters under any conditions. If your project includes dewatering, you must include dewatering plans and discharge locations in your site Stormwater Pollution Prevention Plan. Location of Discharge into Surface Waterbody Enter the waterbody name and latitude/longitude of the point(s) where the site has the potential to discharge into a waterbody (enter all locations). • Include the names and locations of both direct and indirect discharges to surface waterbodies, even if the risk of discharge is low or limited to periods of extreme weather. • Some large construction projects (for example, subdivisions, roads, or pipelines) may discharge into several waterbodies. • If the creek or tributary is unnamed, use a format such as “unnamed tributary to Deschutes River.” • Attach a separate list if necessary.

REDMOND CENTRAL CONNECTOR  Redmond, Washington

INTRODUCTION This report presents results of our geotechnical engineering services for the Redmond Central Connector (RCC) project in Redmond, Washington. The site is shown relative to surrounding physical features on the Vicinity Map, Figure 1, and the Site Plans, Figures 2 and 3. The purpose of this study was to complete subsurface explorations at the project site and to provide geotechnical engineering conclusions and recommendations for the design and construction of the proposed improvements. GeoEngineers is concurrently providing permitting services for this same site as a separate project. We issued this report in draft form on November 23, 2011 and the report was updated and reissued on February 17, 2012. This final report incorporates project team comments from review of the draft and updated reports as well as additional information developed during additional evaluations completed subsequently. Therefore, this final report supersedes all prior reports. Our geotechnical engineering services were completed in general accordance with the Subconsultant Agreement between GeoEngineers, Inc. (GeoEngineers) and The Berger Partnership PS (TBP) dated July 21, 2011. We also provide supplemental services and a contract amendment for those services is being processed currently. Our scope of work includes:

■ Reviewing background data including geologic maps, topographical maps, and geotechnical engineering studies of the site and vicinity, as available and appropriate;

■ Completing a reconnaissance and explorations (borings) along the Burlington Northern Santa Fe (BNSF) embankment to characterize the subsurface conditions along the project alignment (initial agreement);

■ Completing a reconnaissance and explorations (hand-augered borings and probes) adjacent to the 170th Avenue NE sidewalk that will be widened to characterize the subsurface conditions (supplemental services);

■ Completing laboratory testing on selected soil samples obtained from the explorations (initial agreement and supplemental services);

■ Evaluating pertinent physical and engineering characteristics of the soils based on the results of the field exploration, laboratory testing and our experience, and provide conclusions and geotechnical recommendations for the following: 

Project Description Our understanding of the project is based on discussions with and information provided by the TBP project team, the City of Redmond, and our experience with similar projects. We understand that the project will construct a regional trail that ties the north and south sides of Downtown within the heart of the City. The trial corridor runs along the former Redmond Spur of the Woodinville Subdivision of the BNSF Rail Corridor, which extends approximately 3.9 miles from the junction of SR-520 and Redmond Way in Southeast Redmond to the intersection of Willows Road and NE 124th Street in the Sammamish Valley neighborhood. The first phase of construction will include a 1.1 mile regional trail and park amenities covering nearly 12 acres of Downtown Redmond. The focus of this geotechnical engineering study is the intersection of RCC and SRT where new infrastructure improvements will include an approximately 500-foot-long ramp descending from the RCC, connecting the two trails. This will entail regrading of the existing embankment and construction of new fill and retaining walls along the connecting trail. We were also subsequently asked to estimate likely soil infiltration rates at the various rain gardens and infiltration pipes that are scattered throughout the entire length of the downtown trail segment. Subsequently, we were asked to evaluate site and subsurface conditions to help complete a new retaining wall and fill to accommodate widening of the sidewalk along a segment of 170 th Avenue NE that will become part of the trail. Note all elevations in this report are NAVD 88.

FIELD EXPLORATIONS AND LABORATORY TESTING Field Explorations The subsurface soil and groundwater conditions at the site were evaluated by drilling four borings, B-1 through B-4, and completing a series of hand-augered borings and hand probes, HA-1, HA-2, P-1, and P-2. These borings were completed using track-mounted, continuous-flight, hollow-stem

Page 2 | March 13, 2012 | GeoEngineers, Inc. File No. 0500-172-01

REDMOND CENTRAL CONNECTOR  Redmond, Washington

auger drilling equipment. The hand-augered borings were completed using a manually operated sampling auger, and the hand probes were completed using a ½-inch-diameter steel probe rod. The approximate locations of the explorations completed for this project are presented on the Site Plans, Figures 2 and 3. Details of the field exploration program and logs of the explorations are presented in Appendix A.

Laboratory Testing Soil samples were collected during the explorations and taken to GeoEngineers’ laboratory for further evaluation. Selected samples were tested for the determination of moisture content, grain size distribution (sieve analysis), and plasticity characteristics (Atterberg limits). A description of the laboratory testing and the test results are presented in Appendix B.

Additional Geotechnical Data Subsurface soil and groundwater information from past projects completed by GeoEngineers and others is attached as Appendix C. This additional information includes the site plans, exploration logs, and laboratory data from the following reports: GeoEngineers, Inc., Geotechnical Engineering Services Report, Redmond Way Stormwater Trunk, Redmond Washington, File No. 0500-149-02, March 11, 2011. GeoEngineers, Inc., Geotechnical Engineering Services Report, 164th Avenue NE Extension, Redmond Washington, File No. 0500-176-02, January 16, 2012.

SITE CONDITIONS Site Geology and Sensitive Area Designations The project alignment is within the floor of the Sammamish River Valley, a broad, north-south trending valley. The Sammamish Valley is the result of glacial scouring during several glacial episodes in the Puget Sound region. The valley was subsequently filled with recessional glacial outwash deposits and post glacial deposits. Recessional outwash deposits primarily include sand, gravel and cobbles with varying amounts of silt. Portions of the valley, including the RCC alignment, have also been filled with alluvial deposits consisting of peat, silt, sand and gravel (surficial soil deposits in the vicinity of the RCC alignment are mapped as such). The ground is disturbed and/or fill has been placed in portions of the valley as a result of past agricultural and construction activities. Sensitive areas maps produced by the City of Redmond indicate that the project area is within a Seismic Hazard Area and Aquifer Recharge Area with High Significance (Wellhead Protection Zone). The seismic hazard is due to the presence of moderately dense sandy alluvium below groundwater that could liquefy if these soils were subjected to strong, earthquake-induced ground shaking. The aquifer recharge sensitive classification is because the upper sand and gravel formation (aquifer) is in direct continuity with the ground surface and is therefore at risk of degradation of water quality from surface spills of contaminants. The City of Redmond water wells are established in this upper sand and gravel aquifer.

Much of the area around the Sammamish River is within the 100-year flood plain delineation and the mapped floodplain encroaches upon portions of the RCC alignment.

Surface Conditions The RCC corridor runs along the former BNSF Rail Corridor. In the Connecting Trail to SRT project area, the RCC is on top of an embankment reaching heights of up to 20 feet in relation to the surrounding grade. The embankment top is ballast covered (Railroad tracks were removed previously) and the side slopes, inclined about 1Â˝H:1V (horizontal to vertical), are vegetated with weeds and brush. The embankment terminates to the west where an existing trestle maintains connectivity from the embankment over at the SRT and Sammamish River. Surface conditions along the remainder of the downtown trail corridor are essentially level ground that is mostly gravel surfaced except where the corridor is crossed by paved roads. Adjacent to 170th Avenue NE the trail crosses through a low drainage area that is crossed by a low railroad trestle. The surrounding developments are consistent with Downtown Redmond core, which is generally developed with low-rise commercial, and/or residential buildings, paved roadways and parking lots, and landscaped areas. The property immediately north of the BNSF embankment within the study area is currently undeveloped. We understand that an extensive buried drainage system is constructed in this vacant lot, which, based on discussion with City utility staff, drains the shopping center to the north of the site.

Subsurface Conditions The subsurface conditions in the Connecting Trail to SRT project area were evaluated by completing four explorations, borings B-1 through B-4. The subsurface conditions in the widened sidewalk at 170th Avenue NE project area were evaluated by completing a series of hand-augered borings and hand probes, HA-1, HA-2, P-1, and P-2. The logs of the explorations are presented in Appendix A. We also reviewed exploration data from available source, which we incorporated into our recommendations for the project. The reviewed data included numerous studies for commercial developments; data from numerous City of Redmond capital improvement projects including roads, utilities and municipal buildings; data from public and private soil and groundwater contamination and remediation studies; and approximately 80 groundwater monitoring wells used by the City of Redmond as part of their wellhead protection monitoring program. Logs of prior explorations are included in Appendix C. Soil

Soil conditions encountered in the borings (Connecting Trail to SRT project area) indicate that soils below the zone of man-made disturbance and fill consist of alluvial deposits of sand, silt, clay and peat underlain by relatively clean sand and gravel alluvium and recessional outwash that extends to the depths explored. The fine-grained silt, clay and peat alluvial deposits are located near the Sammamish River (borings B-1 through B-3) and likely near Bear Creek, as well. The very soft to very stiff silts, clays and organics are found to depths of 13 to 17 feet (Elevation 18 to 21 feet) in these three borings. These borings also encountered several feet of diatomaceous earth directly

REDMOND CENTRAL CONNECTOR  Redmond, Washington

below the turf zone. It should be noted that it has been standard City of Redmond practice to remove diatomaceous earth for roadway projects. The fill soils within the BNSF embankment, as encountered in B-4, consists of silty sand with gravel that is generally in a very loose to loose condition. A void measuring about 1 to 1½ feet was encountered in the embankment at about 3 feet below the ground surface (bgs) in boring B-4. Fill soils occasionally contain some building debris. The native soils below the fill and the fine grained alluvium (below Elevation 18 to 21 feet in the borings), generally consist of coarse-grained alluvium and outwash (medium dense to very dense sand and gravel with variable silt content). Previous experience in the area suggests that there may be abundant oversized material in the coarse-grained alluvium and outwash. Excavations in the area have encountered abundant cobbles and occasional boulders. The soils below the trail corridor east of the BNSF embankment consist of fill and native deposits. The soils below the zone of man-made disturbance consist of relatively clean sand and gravel alluvium and recessional outwash that extend to depths more than 30 or 40 feet. The soils in the zone of man-made disturbance are generally in a loose to medium dense condition and range up to several feet in thickness. Fill soils occasionally contain some building debris. It should be noted that the corridor east of the embankment has recently been disturbed during the installation of a large diameter stormwater pipe that extended to depths in excess of 15 feet. The soils within the pipe zone should now be classified as fill to the full depth of the pipe zone. The hand explorations completed in the vicinity of the widened sidewalk at 170 th Avenue NE encountered silty sand with gravel and occasional cobbles, interpreted as fill, to about Elevation 35½ feet underlain by silt with sand and trace organic matter to about Elevation 31 feet. Below about Elevation 31 feet, the hand explorations were terminated due to practical refusal conditions on a dense soil, assumed to be the sand and gravel aquifer present below the City’s core. Groundwater Conditions

Alluvium and outwash deposits form an extensive and prolific aquifer that extends beneath the City of Redmond. The aquifer is fed from the east by recharge and aquifer through flow generated in Bear Creek and Evans Creek valleys. Groundwater typically flows from east to west through the downtown Redmond area and is in hydraulic continuity with the Sammamish River, the stage of which strongly controls groundwater levels in the aquifer. Groundwater is relatively shallow and fluctuates seasonally and also in response to flood events with both direct infiltration as well as in response to the water level in the Sammamish River and in Bear Creek. As part of the City’s wellhead protection program, a numerous array of wells distributed throughout the city have been read regularly over the past several years affording a database of groundwater levels throughout the city and subsequently around the project area. Groundwater data indicate that the seasonal low and high levels at the study area (RCC near the SRT) range between approximately Elevation 23 and 28 feet. Groundwater rises to the east and is typically about 5 feet higher in the eastern end area of the RCC corridor for both seasonal highs and lows.

March 13, 2012 | Page 5 File No. 0500-172-01

REDMOND CENTRAL CONNECTOR  Redmond, Washington

Groundwater levels were observed at the time of drilling at around Elevation 20 to 22½ feet (borings completed near the Connecting Trail to SRT project area) and perched water was encountered around Elevation 38 feet in the hand explorations completed in the vicinity of the widened sidewalk at 170th Avenue NE. The observed levels are in general agreement with the expected range of the available historical data. However, the depths to groundwater noted at the time of drilling represent conditions observed during the exploration and may not represent the true static groundwater level because it can take hours or even days for the groundwater level observed in a boring to reach equilibrium. All projected groundwater elevations given in this section are estimates provided for general guidance only. Groundwater conditions to be encountered in excavations for construction will depend on the time of year, amount of recent and previous rainfall, stage of the Sammamish River and other indeterminate factors.

CONCLUSIONS AND RECOMMENDATIONS Summary of Geotechnical Considerations We conclude that the planned improvements can be successfully completed from a geotechnical perspective, provided the considerations presented in this report are incorporated into the project planning and design. A summary of the primary geotechnical considerations is provided below. The summary is presented for introductory purposes only and should be used in conjunction with the complete recommendations presented in this report.

■ Within the BNSF embankment study area (within about 500 feet southeast of the SRT), the near surface native soils that surround and underlie the railroad embankment fill consist of compressible silt, clay and organic rich deposits, including diatomaceous earth. 

These soils are generally not suitable for concentrated load foundation support.



These soils are highly moisture sensitive.

■ The fill soils within the railroad embankment are suitable for reuse as structural fill; albeit only during dry weather grading. Because the embankment fill contains a significant amount of silt, we recommend that they not be used for structural fill during the wet season.

■ The soils near the Sammamish River are only suitable for slow stormwater infiltration. Accordingly, we recommend that consideration be given to incorporating an underdrain into the rain gardens near the Sammamish River.

■ The soils below the remainder of the downtown trail segment are suitable for moderate stormwater infiltration for shallow facilities. High infiltration rate soils are present in a few of the borings in downtown; however, they are not pervasive or continuous.

■ The groundwater level was encountered in the borings at the BNSF embankment at about 13 to 15 feet below the current site grade. Groundwater data in this area indicate that the seasonal low and high levels at the study area range between approximately Elevation 23 and 28 feet. Groundwater rises to the east across downtown Redmond up to a seasonal high level near Bear Creek of 34 feet (NAVD 88). These groundwater levels need to be considered for designing the depths of stormwater infiltration facilities.

■ Various alternatives for accomplishing the trail down the railroad embankment to the SRT have been discussed by the project team that included a pile supported elevated structure and several embankment supported trail alternatives with and without retaining walls. We previously provided recommendations for pile support of the elevated structure; however, that alternative was not selected because of the associated high costs. Therefore, we have deleted from this report the sections that pertained to the elevated structure. This report contains recommendations and considerations that pertain to the embankment supported trail alternative with retaining walls. These and other geotechnical considerations are discussed further, and recommendations pertaining to the geotechnical aspects of the project are presented in the following sections of this report.

Earthquake Engineering 2009 IBC Seismic Design Information

For this site, we recommend the following 2009 IBC parameters for Site Class, short period spectral response acceleration (SS), 1-second period spectral response acceleration (S1), and Seismic Coefficients Fa and Fv. The values presented below in Table 1 are based on the 2002 USGS National Seismic Hazards Mapping project for determining a peak ground (bedrock) acceleration coefficient for design.

Recommended Value E 122.2

1-Second Period Spectral Response Acceleration, S1 (percent g)

41.4

Seismic Coefficient, Fa

0.9

Seismic Coefficient, Fv

2.4

Seismic Hazards

We evaluated the site conditions for seismic hazards including liquefaction, lateral spreading, and seismically induced landsliding. Our evaluation indicates the site has moderate risk of liquefaction because of the presence moderately dense relatively clean sands below the groundwater level. Because there is a moderate risk of liquefaction, the site has a moderate risk of liquefaction-induced ground disturbance. There is also a low potential for seismically induced landsliding and/or lateral spreading resulting from liquefaction. Surface Fault Rupture

Based on USGS maps of active faults in the Puget Sound region, the site is located approximately 6½ miles north of the Seattle Fault Zone. Because the thickness of Quaternary sediments below the site, which are commonly more than 1,000 feet thick, and lack of fault displacement evidence in the area, the potential for surface fault rupture is considered very remote.

Earthwork General

Fill and alluvial deposits underlain by relatively clean sand and gravel alluvium and recessional outwash were observed in the explorations. We anticipate that these soils observed in the explorations can be excavated with conventional grading equipment, such as track excavators or dozers. The contractor should be prepared to deal with oversize material (cobbles and boulders) in the native soils and perhaps rubble within the BNSF embankment fill. It may be possible to bury some of the cobbles and boulders, if encountered, in the deeper portions of the new connector trail ramp. Rubble cannot be placed in fill and should be removed and properly disposed of. Clearing and Grubbing

Significant clearing and grubbing is not expected with the current improvements as planned, and these activities are expected to be limited to the removal of existing vegetation. The work area should be cleared of all surface and subsurface deleterious matter, including debris, trees, shrubs and associated stumps and root wads, and should be stripped of any sod and organic soil. The woody debris should be removed from the project site for disposal. Removal and demolition of existing structures should include removal of below-grade elements. Existing voids or new depressions created during site preparation should be cleaned of loose soil or debris and backfilled with structural fill. Erosion and Sedimentation Control

Potential sources or causes of erosion and sedimentation depend upon construction methods, slope length and gradient, amount of soil exposed and/or disturbed, soil type, construction sequencing and weather. The project’s impact on erosion-prone areas can be reduced by implementing an erosion and sedimentation control plan. The plan should be designed in accordance with applicable City and/or county standards. The plan should incorporate basic planning principles including:

■ Scheduling grading and construction to reduce soil exposure; ■ Retaining existing vegetation whenever feasible; ■ Revegetating or mulching denuded areas; ■ Directing runoff away from denuded areas; ■ Minimizing the length and steepness of slopes with exposed soils; ■ Decreasing runoff velocities; ■ Confining sediment to the project site; ■ Inspecting and maintaining control measures frequently; ■ Covering soil stockpiles; and ■ Implementing proper erosion control BMPs. Page 8 | March 13, 2012 | GeoEngineers, Inc. File No. 0500-172-01

REDMOND CENTRAL CONNECTOR ď Ž Redmond, Washington

Temporary erosion protection should be used and maintained in areas with exposed or disturbed soils to help reduce the potential for erosion and reduce transport of sediment to adjacent areas. Temporary erosion protection should include the construction of a silt fence around the perimeter of the work area prior to the commencement of grading activities. Permanent erosion protection should be provided by reestablishing vegetation using hydroseeding and/or landscape planting. Until the permanent erosion protection is established and the site is stabilized, site monitoring should be performed by qualified personnel to evaluate the effectiveness of the erosion control measures and repair and/or modify them as appropriate. Provisions for modifications to the erosion control system based on monitoring observations should be included in the erosion and sedimentation control plan. Subgrade Preparation

Prior to the placement of new fill, subgrade areas should be proof-rolled to locate areas of loose, soft or pumping soils. Proof-rolling can be completed using a piece of heavy tire-mounted equipment or a loaded dump truck. If soft or pumping soils are observed, such unsuitable subgrade soils should be recompacted or overexcavated and replaced. The depth of overexcavation should be determined by the Geotechnical Engineer. If deep pockets of soft or pumping soils are encountered, it may be possible to limit the depth of overexcavation by placing a construction geotextile for separation/soil stabilization (Washington State Department of Transportation [WSDOT] Standard Specification 9-33) on the overexcavated subgrade and covering the geotextile with structural fill. The geotextile will provide additional support by bridging over the soft material, and will help reduce fines contamination into the structural fill. The need for geotextile fabric and overexcavation should be evaluated by the Geotechnical Engineer. The Geotechnical Engineer should monitor the subgrade preparation operations to help determine the depth of removal of soft or pumping soils, and to evaluate whether subgrade disturbance or progressive deterioration is occurring. Subgrade disturbance or deterioration could occur if the subgrade is wet and cannot be dried. If the subgrade deteriorates during proof-rolling or compaction, it may become necessary to modify the proof-rolling or compaction criteria or methods. Structural Fill Materials

Materials used to construct roadways and embankments, backfill utility trenches, vaults or other structures are classified as structural fill for the purpose of this report. Structural fill material quality varies depending upon its use, as described below: 1. As a minimum, structural fill placed to construct embankments and roadways and to backfill utility trenches, vaults or other structures should meet the criteria for common borrow, WSDOT 9-03.14(3). Common borrow will be suitable for use as structural fill during dry weather conditions only. The existing railroad embankment fill generally qualifies as common borrow. 2. If structural fill is placed during wet weather, the structural fill should consist of gravel borrow, WSDOT 9-03.14(1).

March 13, 2012 | Page 9 File No. 0500-172-01

REDMOND CENTRAL CONNECTOR  Redmond, Washington

3. Pipe bedding placed to surround utility pipe should meet the criteria for gravel backfill for pipe zone bedding, WSDOT Standard Specifications Section 9-03.12(3). 4. Structural fill placed as crushed surfacing base course below pavements should conform to WSDOT 9-03.9(3). ON-SITE SOILS

The near surface native on-site soils adjacent to the BNSF embankment and 170th Avenue sidewalk widening generally contain a high percentage of fines (silt and clay) and/or organic matter and are highly moisture sensitive and not suitable for reuse as structural fill. These materials are capable of supporting the new connecting trail fill. The railroad embankment fill generally qualifies as common borrow and can be used for structural fill; however, only during dry weather conditions. We recommend against using the embankment fill for structural fill during wet weather conditions. FILL PLACEMENT AND COMPACTION CRITERIA

Structural fill should be mechanically compacted to a firm, non-yielding condition. Structural fill should be placed in loose lifts not exceeding 1 foot in thickness. Each lift should be conditioned to the proper moisture content and compacted to the specified density before placing subsequent lifts. Structural fill should be compacted to the following criteria: 1. Structural fill in embankment and new pavement areas, including utility trench backfill, should be compacted to 90 percent of the maximum dry density (MDD) determined in general accordance with the American Society for Testing and Materials [ASTM] D 1557 test method), except that the upper 2 feet of fill below final subgrade should be compacted to 95 percent of the MDD (ASTM D 1557). 2. Structural fill placed to support foundations/structures should be compacted to 95 percent of the MDD (ASTM D 1557). 3. Crushed surfacing base course below pavements should be compacted to 95 percent of the MDD (ASTM D 1557). We recommend that monitoring of the placement of backfill be provided to observe that the required compaction criteria are being met, the proper materials are used for structural backfill and that the contractor is placing the material in appropriate lifts for the compaction equipment being employed. The near surface native on-site soils adjacent to the BNSF embankment and 170th Avenue sidewalk widening generally contain a high percentage of fines (silt and clay) and/or organic matter and are highly moisture sensitive. Disturbance of exposed soils should be expected if earthwork is completed during periods of wet weather. For wet weather construction, we recommend that:

■ The ground surface in and around the work area should be sloped so that surface water is directed away from the work area.

■ Slopes with exposed soils should be covered with plastic sheeting or similar means of protection.

Page 10 | March 13, 2012 | GeoEngineers, Inc. File No. 0500-172-01

REDMOND CENTRAL CONNECTOR  Redmond, Washington

■ The contractor should take necessary measures to prevent fill soils from becoming wet or unstable. These measures may include the use of plastic sheeting, sumps with pumps, and grading. Construction activities should be scheduled so that the length of time that soils are left exposed to moisture is reduced to the extent practical. The contractor must make sure that temporary erosion and sedimentation measures also meet all requirements of the City of Redmond, and all other permitting agencies. Temporary Slopes

We recommend that temporary unsupported cut slopes higher than 4 feet be inclined no steeper than 1½H:1V. This recommendation applies to the native soils and the embankment fill. This recommendation applies to fully dewatered conditions. Flatter slopes may be necessary if seepage is present on the cut face. Temporary cut slopes should encroach no closer than 5 feet laterally from roadways, pavements, structures or other improvements. Some sloughing and raveling of the cut slopes should be expected. Temporary covering, such as heavy plastic sheeting, should be used to protect these slopes during periods of rainfall. Surface water runoff from above cut slopes must be prevented from flowing over the slope face by using curbs, berms, drainage ditches, swales or other appropriate methods. If temporary cut slopes experience excessive sloughing or raveling during construction, it may become necessary to modify the cut slopes to maintain safe working conditions and protect adjacent facilities or structures. Slopes experiencing excessive sloughing or raveling can be flattened or can be regraded to add intermediate slope benches, or additional dewatering can be provided if the poor slope performance is related to groundwater seepage. Permanent Slopes

We recommend that permanent unreinforced cut and fill slopes be constructed no steeper than 2H:1V. Steeper permanent fill slope inclinations can be achieved by reinforcing the fill with geogrids. If the geogrids extend only to the face of the slope, the slope can be inclined at a maximum steepness of 1½H:1V. Steeper fill slope face inclinations can be achieved by wrapping the geogrid around the outer face of the fill lifts (burrito wrap) or by introducing a facing element at the outer face of the fill lifts. Considerations related to reinforced earth slopes are discussed in greater detail in the subsequent “Trail Embankment” section of this report. To achieve uniform compaction, we recommend that unreinforced fill slopes be overbuilt slightly (1 foot) and subsequently cut back to expose properly compacted fill. We recommend that the finished slope faces be compacted by track walking with the equipment running perpendicular to the slope contours so that the track grouser marks help provide an erosion-resistant slope texture. Reinforced fill slopes without facing wraps or facing elements should also be track walked if feasible; however, care should be exercised to avoid damaging the reinforcement material. To reduce erosion, newly constructed slopes should be planted or hydroseeded shortly after completion of grading. Until the vegetation is established, some sloughing and raveling of the slopes should be expected. This may require localized repairs and reseeding. Temporary covering,

REDMOND CENTRAL CONNECTOR  Redmond, Washington

such as clear heavy plastic sheeting, jute fabric, loose straw, or excelsior or straw/coconut matting should be used to protect the slopes during periods of rainfall.

Infiltration Evaluation We understand the Low Impact Design (LID) improvements that will be incorporated into the project will consist of rain gardens (bioretention), infiltration pipes. and trenches for stormwater management. Pursuant to the 2005 Department of Ecology (DOE) Stormwater Management Manual for Western Washington (SMMWW), design infiltration rates shall be determined using one of the three methods outlined in Volume III, Chapter 3 and Appendix C of the DOE Manual (SMMWW); USDA Textural Classification, ASTM Gradation, or In-Situ Infiltration Measurements. It should be noted that Ecology is in the process of drafting an updated SMMWW that is slated for final issuance in 2012, the guidelines of which may not concur with the current 2005 issue and the recommendations herein for selection of design infiltration parameters for LID improvements. Two methods were used to evaluate an appropriate design infiltration rate for the various soils encountered at the site in the current explorations. The methods consist of correlations based on United States Department of Agriculture (USDA) soil textural classification and ASTM gradation testing, as discussed in Section 3.3.6 of the SMMWW (Ecology, 2005). Table 2 presents a summary of the estimated infiltration rates at two of the recent borings based on the two methods: (1) USDA textural class and (2) ASTM laboratory gradation testing. Groundwater conditions at the site are summarized in the “Subsurface Conditions” section of this report. TABLE 2. INFILTRATION DATA

We were subsequently asked to help evaluate stormwater infiltration rates for the various rain gardens, infiltration pipes, and trenches that are planned for the remainder of the downtown trail segment. This evaluation is to be based on the existing available subsurface information that is nearest to the various facilities. We reviewed the available boring data at or nearest to the proposed infiltration locations to estimate the likely infiltration rates for shallow stormwater infiltration. We preface this information by noting that much of the area along the RCC corridor has been highly disturbed by past activity

Page 12 | March 13, 2012 | GeoEngineers, Inc. File No. 0500-172-01

REDMOND CENTRAL CONNECTOR ď Ž Redmond, Washington

including the original railroad line construction, construction of the roads and utilities that cross the corridor, site remediation activities at the old King County Shops site west of Leary Way, and, most recently, by the installation of the Downtown Redmond Stormwater Collection Pipeline. Because of this past disturbance, subsurface conditions in the borings may not accurately represent the current subsurface conditions at the proposed infiltration facilities. The design infiltration rate for an individual facility will depend on the type of facility. Long Term Design Infiltration Rates for infiltration pipes and trenches must incorporate a correction factor to account for site variability, maintenance to prevent siltation and bio clogging, etc. As discussed in greater detail below, Long Term Infiltration Rates for rain gardens that incorporate an amended soil (bioretention soil) layer must be the lower of the long-term rate of the amended soil or the initial (Short Term) infiltration rate of the underlying (native) soil. Correction factors need not be applied to the Short Term Infiltration Rate of the native soil. Based on the boring data, the surficial soils along the majority of the RCC corridor likely have an uncorrected, Short Term Infiltration Rate of 8 inches per hour, in our opinion. Sandy gravel is locally present below the site; however, it is not pervasive or continuous. If an infiltration pipe is completed in a sandy gravel deposit, the design long-term infiltration rate can be raised to 10 inches per hour. Based on discussions with the design team, we understand that the project infiltration pipes are intended to be sited in the sandy gravel and that they will be designed using a long-term infiltration rate of 10 inches per hour. We also understand that the subsurface conditions at each pipe will be explored prior to construction to verify the presence of sandy gravel soils and that infiltration tests will be performed to verify the design infiltration rate. We concur with this approach. For bioretention areas (rain gardens), Section 7.7 of Appendix C of the 2005 Ecology Manual, Subsection 7.7.4 Infiltration Rate Determinations, states that the assumed infiltration rate for the bioretention area must be the lower of the long-term rate of the imported soil (amended soil) or the initial (short-term) infiltration rate of the underlying (native) soil. This section also states that the underlying native soil does not need a (infiltration rate) correction factor because the overlying imported soil protects it. Accordingly, we propose that LID improvements which incorporate an amended soil layer be designed using the lower of the amended soil long-term infiltration rate or the short-term infiltration rate of the native soil based on values determined using the USDA soil textural classification. We recommend that the Long Term Design Infiltration Rate for the majority of the rain gardens be assumed to be 2Â˝ inches per hour; this corresponds to our estimated infiltration rate for a typical amended/bioretention soil. The soils near the rain garden at Station 13+46 consist of silt that has an estimated Long Term Design Infiltration Rate of less than Â˝ inches per hour. The nearest boring to the rain garden at Station 57+77 is about 175 feet to the east. The soils in that boring suggest a Short Term Infiltration rate of 2 inches per hour. Because this rate is lower than the estimated infiltration rate of the amended/bioretention soil, it should be considered the design infiltration rate for this rain garden.

The City of Redmond Clearing, Grading and Stormwater Management Technical Notebook, dated January 1, 2007 with Addendum dated August 18, 2010, supplement the 2005 Ecology SMMWW and defines how the Ecology Manual is to be applied in Redmond. The August 18, 2010 Appendix contains the following provisions that pertain to stormwater infiltration:

■ Section 2.9.3 revises Volume III of the Ecology Manual in the following ways: 

Sub-Section 3.3 – Infiltration Facilities for Flow Control and Treatment. Infiltration of stormwater is limited in Wellhead Protection Zones.



Sub-Section 3.3.5 – Site Characterization Criteria. Infiltration is unacceptable if the design infiltration rate is less than 1 inch per hour and the rate cannot be greater than 20 inches per hour.



Sub-Section 3.3.9 – General Design, Maintenance and Construction Criteria for Infiltration Facilities. Construction plans shall include a note to require field verification during construction of the facility, of soil conditions, and infiltration rates by an engineer with experience in stormwater management and licensed in the State of Washington. The engineer shall provide a written statement to the City of Redmond related to the field verification of the design parameters.

■ Section 2.9.5 revises Volume V of the Ecology Manual in the following ways: 

Sub-Section 2.9.5.7 – Chapter 7 – Infiltration and Bio-Infiltration Facilities. This provision stipulates that infiltration for treatment is not allowed in Wellhead Protection Zones 1, 2 or 3.

We recommend that the construction plans for this project include a statement that is consistent with the Redmond August 18, 2010 Appendix revision of Sub-section 3.3.9 of the Volume III Ecology Manual.

Rain Garden Site Preparation In addition to the recommendations presented above under Earthwork Considerations, we recommend the following site preparation recommendations for rain gardens and other LID facilities. Rain gardens should be excavated to final depth and configuration using equipment that operates outside the footprint of the rain garden. Under no circumstances should equipment be allowed with the footprint of the rain garden; otherwise the native soil subgrade could be compacted by the weight of the equipment and possibly reduce the infiltration performance of the soil. Consideration should be given to hand raking the final subgrade to help scarify the subgrade. Depending on the type of native soil below the rain garden, consideration should be given to placing a non-woven geotextile (Mirafi 140N, or sim.) on the native soil subgrade prior to placing the retention zone gravel (if used) or amended soil in the rain garden. A geotextile should also be placed between the retention zone gravel (if used) and the amended soil. Stormwater runoff should not be allowed to enter the rain garden until the vegetation is established. This is particularly critical during the construction phase when stormwater runoff can be very silty.

Connecting Trail to Sammamish River Trail The project team discussed several alternatives for the trail down from the railroad embankment to the SRT. We understand that the preferred alternative is to complete the trail on a new widened embankment with retaining walls. The following sections present recommendations for this alternative. Trail Embankment

We understand that the widened embankment is intended to be constructed against to the north face of the BNSF embankment. We recommend that the widened embankment be constructed in accordance with the recommendations presented in the “Earthwork” section of this report. The proximity to the adjacent property boundary may prevent the new trail embankment from being completed with a finished face of 2H:1V necessitating a structure at the base of the slope to truncate the fill. Recommendations for design of retaining walls are presented subsequently. Alternatively, the face of the fill can be oversteepened by incorporating geogrids (reinforced earth) in the fill prism that effectively strengthens the fill. The face of the fill can be completed at a steepness of 1½H:1V with geogrids placed at every 2 feet vertically within the fill. The length of the grids will be a function of the overall height of the reinforced fill embankment and the type of soil used to construct the embankment. We recommend assuming that the grids lengths equal 70 percent of the height of the reinforced slope. We recommend using a grid with a strength of 1200 pounds per foot in the cross direction (roll width direction) such as Tensar BX1300 (or similar strength material). The grids should be located immediately behind the face of the slope. A steeper embankment can be achieved by incorporating facing elements that are connected to the geogrids to create a Mechanically Stabilized Earth (MSE) wall. Geotechnical parameters for design of MSE walls are also presented subsequently.

170th Avenue NE Widened Sidewalk We understand that a relatively short retaining wall is planned to accommodate the planned sidewalk widening where the trail intersects east side of 170 th Avenue NE. We recommend that the retaining wall be design in accordance with the “Earthwork” and “Retaining Wall Design Considerations” sections of this report.

Retaining Wall Design Considerations Retaining walls for this project can consist of gravity block walls or concrete cantilever walls. For these walls we recommend using an equivalent fluid density of 33 pounds per cubic foot (pcf) to calculate active earth pressures acting on the wall. This value of active earth pressure assumes a level back-slope. We recommend a rectangular seismic pressure acting over the height of the wall equal to 6H psf, where H is the height of the wall in feet. If the walls will be subjected to the influence of surcharge loading (for example, traffic loading) within a horizontal distance equal to the height of the wall, the walls should be designed for the additional horizontal pressure using an appropriate design method. A common practice is to assume a surcharge loading equivalent to 2 feet of additional fill to simulate traffic loading; we consider this method appropriate for typical situations. Where large surcharge loads such as from

March 13, 2012 | Page 15 File No. 0500-172-01

REDMOND CENTRAL CONNECTOR  Redmond, Washington

heavy trucks, cranes, or other construction equipment are anticipated in close proximity to the retaining walls, the walls should also be designed to accommodate the additional lateral pressures resulting from these concentrated loads. Retaining walls should be supported on medium dense or denser granular fill soils. If the foundation subgrade is determined to be soft, the subgrade should be overexcavated to a depth of two feet and replaced with crushed gravel. It will also help to place a woven geotextile fabric on the subgrade at the base of the overexcavation to help bridge over the soft soil. A geotextile similar to TenCate Mirafi 500X should be used in this situation. Retaining wall footings should be embedded slightly below the adjacent ground surface. Gravity block walls should be embedded at least 1 foot below grade. Concrete retaining walls should be embedded 2 feet below grade. These wall footings may be designed using an allowable average soil bearing value of 3,000 psf, with a maximum toe bearing pressure of 4,500 psf. These allowable soil bearing values apply to the total of dead and long-term live loads and may be increased by up to one-third for seismic loads. Lateral wall loads can be resisted by a combination of friction between the footing and the supporting soil. If the wall footing is embedded deeper than 2 feet below grade it can also be evaluated using the passive lateral resistance of the soil surrounding the embedded portions of the footings. A coefficient of friction between concrete and soil of 0.45 and a passive lateral of 250 pcf can be used for design. We recommend that the upper 2 feet of passive resistance be ignored. The friction coefficient and passive lateral resistance are allowable values and include a factor of safety of 1.5. If soils adjacent to footings are disturbed during construction, the disturbed soils must be recompacted; otherwise the lateral passive resistance value must be reduced. Recommendations for wall drainage are given in the section below titled “Wall Drainage.” Mechanically Stabilized Earth Walls

MSE retaining walls are often a cost-effective method for support of fill embankments, provided sufficient space is available for the back-cut required for placement of the reinforcing materials. Design of such a wall system must be based on site-specific conditions and geotechnical parameters. Pre-cast concrete members (panels or blocks) are widely used as facing elements. Principal advantages of MSE walls include relatively low unit cost and tolerance of relatively large differential settlements. MSE walls consist of alternating layers of backfill soil and reinforcing material with facing elements. Commonly used reinforcing elements include steel strips and various geosynthetic products such as geogrid and geotextile sheets. The vertical spacing of the reinforcing elements is typically on the order of 1 to 3 feet. For MSE walls designed using the IBC level seismicity, the reinforcing material lengths are typically on the order of 80 percent of the wall height, which includes the embedment depth in addition to the exposed height of the wall. The actual reinforcing material spacing and length will be determined by the wall designer and will depend on the reinforcing material specified

Page 16 | March 13, 2012 | GeoEngineers, Inc. File No. 0500-172-01

REDMOND CENTRAL CONNECTOR  Redmond, Washington

and other parameters. If geosynthetic products are selected, long term creep characteristics should be taken into consideration in product selection. Many MSE proprietary wall systems are available. The design procedures and wall details of several proprietary wall systems have been evaluated by WSDOT, which has resulted in a pre-approved status for certain walls. An agreement between WSDOT and the proprietary wall manufacturers exists for pre-approved systems, which allows the proprietary wall manufacture to competitively bid a particular project without having to provide a detailed wall design in the contract plans. Pre-approved proprietary wall systems with specific requirements and details are available in the Appendix of Chapter 15 of the WSDOT Geotechnical Design Manual (GDM). WSDOT should be contacted for a current list of the pre-approved proprietary systems prior to choosing the system. We recommend that proprietary wall system designs be reviewed by the Geotechnical Engineer to confirm that valid assumptions were made relative to material properties, site conditions and other factors. DESIGN PARAMETERS

We recommend the design parameters summarized in Table 3 for use in design of MSE walls. The values shown below assume the backfill soil is compacted as recommended in the “Earthwork” section of this report. TABLE 3. RECOMMENDED DESIGN PARAMETERS FOR MSE WALLS Reinforced Zone Soil

The MSE walls should be designed for seismic loading as discussed in the “Earthquake Engineering” section of this report. In accordance with the GDM, MSE walls that are free to translate or move during a seismic event should be designed with a reduced coefficient of horizontal acceleration (kh) of approximately half of the peak ground acceleration (PGA) for the site. For the project site, half of the PGA equates to 0.15g. Alternatively, the value of the horizontal coefficient of acceleration can be calculated using the Mononobe-Okabe method specified in Article 11.6.5 of the AASHTO LRFD Bridge Design Specifications. The vertical coefficient of acceleration (kv) shall be set to 0 for the analysis.

March 13, 2012 | Page 17 File No. 0500-172-01

REDMOND CENTRAL CONNECTOR  Redmond, Washington

The minimum embedment depth of the MSE retaining walls will be a function of the height of the wall and the slope in front of the wall. We recommend that the permanent cut slopes in front of and above the MSE wall be inclined no steeper than 1½H:1V. Temporary cut slopes to install the MSE walls should be inclined no steeper than 1½H:1V. The minimum embedment depth for walls founded on sloping ground should be provided as described in Table 4 but should not be less than 2 feet. In addition, the minimum embedment depth should be provided below a theoretical 4-foot-wide horizontal bench that extends from the face of the wall and intersects the sloping ground in front of the wall. TABLE 4. MINIMUM EMBEDMENT DEPTHS FOR MSE WALLS Slope in Front of Wall

Minimum Embedment Depth (feet)

If the MSE walls will be subjected to the influence of surcharge loading (for example, traffic loading) within a horizontal distance equal to the height of the wall, the walls should be designed for the additional horizontal pressure using an appropriate design method. A common practice is to assume a surcharge loading equivalent to 2 feet of additional fill to simulate traffic loading; we consider this method appropriate for typical situations. Where large surcharge loads such as from heavy trucks, cranes, or other construction equipment are anticipated in close proximity to the retaining walls, the walls should also be designed to accommodate the additional lateral pressures resulting from these concentrated loads. The foundation subgrade for the MSE walls should be prepared in accordance with the recommendations provided in the “Earthwork” section of this report. We recommend that the condition of all MSE wall foundation excavations be observed by the Geotechnical Engineer to evaluate if the work is completed in accordance with our recommendations and that the subsurface conditions are as expected. Recommendations for wall drainage are given in the section titled “Wall Drainage.” Wall Settlement

Provided all loose soil is removed and the subgrade is prepared as recommended under Construction Considerations below, we estimate the total settlement of wall foundations will be on the order of 1 to 1½ inches. The settlements will occur rapidly, essentially as loads are applied. Differential settlements over 100 feet of wall length are expected to be on the order of half the total settlement. GeoEngineers can provide more accurate settlement estimates once the wall alignment, foundation elevation, and wall heights are established. Wall Drainage

Positive drainage should be provided behind concrete, gravity block, and MSE walls. For concrete and gravity block walls, drainage should be provided by placing a 2-foot-wide zone of gravel backfill for walls (WSDOT 9-03.12(2)) against the rear face of the wall and draining the gravel with a 4-inch-diameter perforated pipe or through weepholes. The perforated pipe should be sloped slightly and lead to a discharge point at the end of the wall or though the face of the wall.

Page 18 | March 13, 2012 | GeoEngineers, Inc. File No. 0500-172-01

REDMOND CENTRAL CONNECTOR ď Ž Redmond, Washington

We recommend using either heavy-wall pipe (SDR-35 PVC) or rigid corrugated polyethylene pipe (ADS N-12, or equal) for the collector pipe. We recommend against using flexible tubing for wall drain pipe. The pipe installations should include cleanouts to allow for future maintenance. Weepholes should be in accordance with the WSDOT Standard Plans and Section 6-02.3(21) of the WSDOT Standard Specifications. MSE walls constructed using common borrow in the reinforced zone can be drained by placing a 4-inch minimum diameter perforated drain pipe at the back of the footing/reinforced zone enveloped within a minimum thickness of 6 inches of gravel backfill for walls (WSDOT 9-03.12(2)). Construction Considerations

If soft or loose areas are present at the foundation subgrade elevation, they should be removed and replaced with lean mix concrete or structural fill at the direction of the Geotechnical Engineer. In such instances, the zone of structural fill should extend laterally beyond the footing edges a horizontal distance at least equal to the thickness of the fill. The condition of all subgrade areas must be observed by the Geotechnical Engineer to evaluate if the work is completed in accordance with our recommendations and that the subsurface conditions are as anticipated.

Traffic Signal and Luminaire Foundations We understand that new traffic signals and luminaires are planned for the project. Pole foundation dimensions and loading have not been finalized; however, we anticipate that all project poles and foundations will comply with WSDOT preapproved signal pole and foundation designs. The following recommendations are based on the WSDOT Geotechnical Design Manual. Design Considerations

Drilled shaft foundations designed in accordance with the 2011 WSDOT Design Manual and 2011 WSDOT GDM, require a lateral-bearing pressure to determine the shaft depth required. The WSDOT design method to estimate lateral-bearing pressures is based on empirical correlations with blow count data and the angle of internal friction of the soil. Pole foundation may be designed using a soil unit weight of 125 pcf, a soil friction angle of 30 degrees, and an allowable lateral bearing pressure of 1,500 psf. These recommendations assume that new pole foundations are founded in medium dense or denser native sand and gravel soils or properly compacted structural fill. Traffic signal pole foundations can be sized in accordance with the criteria presented on WSDOT Standard Plan J-26.10-00. Luminaire pole foundations can be sized in accordance with the criteria presented on WSDOT Standard Plan J-28.30-01. Construction Considerations

We recommend that drilled shaft foundations for the poles be installed using the WSDOT procedure. Concrete should be cast near against excavation sides. The use of temporary casing, drilling mud or other types of procedures should be used, as necessary, to control sloughing of

March 13, 2012 | Page 19 File No. 0500-172-01

REDMOND CENTRAL CONNECTOR  Redmond, Washington

sidewalls. However, any casing should be removed while the concrete is still fluid so that proper soil/cement contact is achieved. Sonotube casings should not be used. Slough should be removed from the bottom of the excavation prior to placement of concrete, as loose or disturbed soil in the excavation base could result in increased settlement. Structures that require relatively short shafts (less than 9 feet deep) may be formed and constructed in an open excavation. Following the removal of the concrete forms (the forms may be left in place ONLY if corrugated metal pipe is used), compacted backfill should be placed around the shaft to provide containment. The backfill placed around the foundation in the excavation must be compacted to at least 95 percent of the MDD (ASTM D1557) and as described in the “Earthwork” section of this report using high quality soil backfill. Controlled density fill may be used as an alternative for structural backfill. We recommend that the Geotechnical Engineer be present during foundation excavation and/or drilling. Geotechnical Engineer should evaluate and confirm the adequacy of the subgrade soils with respect to the anticipated conditions based on the borings and foundation design recommendations presented in this report.

Additional Geotechnical Services Throughout this report, recommendations are provided where we consider additional geotechnical services to be appropriate. These additional services are summarized below:

■ We recommend completing additional explorations (test pits) at the infiltration pipe facility locations. The purpose of this is to evaluate the presence and depth of gravel that could accommodate an infiltration rate of 10 inches per hour.

■ During construction, the Geotechnical Engineer should observe and evaluate the excavations, the suitability of subgrade soils, the suitability and the compaction of the backfill, and the installation of deep foundation elements. The purposes of the Geotechnical Engineers’ construction phase services are to confirm that the subsurface conditions are consistent with those observed in the explorations and other reasons described in Appendix D, Report Limitations and Guidelines for Use.

LIMITATIONS We have prepared this report for the exclusive use of the City of Redmond, TBP and other project team members for the RCC project in Redmond, Washington. The data should be provided to prospective contractors for their bidding or estimating purposes, but our report and interpretations should not be construed as a warranty of the subsurface conditions. Within the limitations of scope, schedule and budget, our services have been executed in accordance with generally accepted practices in the field of geotechnical engineering in this area at the time this report was prepared. No warranty or other conditions, express or implied, should be understood.

APPENDIX A Field Explorations

REDMOND CENTRAL CONNECTOR  Redmond, Washington

APPENDIX A FIELD EXPLORATIONS General Subsurface conditions at the site were explored by drilling four borings, B-1 through B-4, and completing a series of hand-augered borings and hand probes, HA-1, HA-2, P-1, and P-2. The borings were completed to depths between about 26½ and 39 feet below the existing ground surface. The drilling was performed by Geologic Drill, Inc. under subcontract to GeoEngineers on October 25, 2011. The hand explorations were completed using a manually operated sampling auger, and the hand probes were completed using a ½-inch-diameter steel probe rod on February 15, 2012. The locations and elevations of the explorations were estimated by taping/pacing from existing site features. The approximate locations of the explorations are shown on the Site Plans, Figures 2 and 3.

Borings The borings were completed using track-mounted, continuous-flight, hollow-stem auger drilling equipment. The borings were continuously monitored by geologist from our firm who examined and classified the soils encountered, obtained representative soil samples, observed groundwater conditions and prepared a detailed log of each exploration. The soils encountered in the borings were sampled at 2½- or 5-foot vertical intervals with a 2-inch outside diameter split-barrel standard penetration test (SPT) sampler. The samples were obtained by driving the sampler 18 inches into the soil with a 140-pound hammer free-falling 30 inches. The number of blows required for each 6 inches of penetration was recorded. The blow count (“N-value”) of the soil was calculated as the number of blows required for the final 12 inches of penetration. This resistance, or N-value, provides a measure of the relative density of granular soils and the relative consistency of cohesive soils. Where very dense soil conditions precluded driving the full 18 inches, the penetration resistance for the partial penetration was entered on the logs. The blow counts are shown on the boring logs at the respective sample depths. Soils encountered in the borings were visually classified in general accordance with the classification system described in Figure A-1. A key to the boring log symbols is also presented in Figure A-1. The logs of the borings are presented in Figures A-2 through A-5. The boring logs are based on our interpretation of the field and laboratory data and indicate the various types of soils encountered. The logs also indicate the depths at which these soils or their characteristics change, although the change may actually be gradual. If the change occurred between samples, it was interpreted. The densities noted on the boring logs are based on the blow count data obtained in the borings and judgment based on the conditions encountered. Observations of groundwater conditions were made during drilling, and these observations represent a short-term condition and may or may not be representative of the long-term groundwater conditions at the site.

REDMOND CENTRAL CONNECTOR  Redmond, Washington

Hand Explorations The hand explorations (hand-augered borings and hand probes) were completed by a representative from our firm who examined and classified the soils encountered, obtained representative soil samples, observed groundwater conditions, and prepared a summary log of each hand exploration. The subsurface conditions encountered in the hand explorations are summarized in the “Subsurface Conditions” section of this report. The locations of the hand explorations are shown on the Site Plan, Figure 3. Hand-augered borings

The hand-augered borings were completed using a manually operated sampling auger. The auger bucket is approximately 3 inches in diameter and 12 inches long and is extended into the ground using a series of extendable rods. The auger was advanced into the soil by hand. The logs of the hand-augered borings are presented in Figures A-6 and A-7. Hand Probes

The hand probe explorations were completed using a ½-inch-diameter steel probe rod. The probe rod was pushed downward through the soil until a hard or dense layer was encountered that precluded advancement of the probe.

APPENDIX B Laboratory Testing

REDMOND CENTRAL CONNECTOR  Redmond, Washington

APPENDIX B LABORATORY TESTING General Soil samples obtained from the explorations were transported to our laboratory and examined to confirm or modify field classifications, as well as to evaluate index properties of the soil samples. Representative samples were selected for laboratory testing consisting of the determination of the moisture content, grain size distribution (sieve analyses), and plasticity characteristics (Atterberg limits). The tests were performed in general accordance with test methods of the American Society for Testing and Materials (ASTM) or other applicable procedures.

Moisture Content Testing Moisture content tests were completed in general accordance with ASTM D 2216 for representative samples obtained from the explorations. The results of these tests are presented on the exploration logs in Appendix A at the depths at which the samples were obtained.

Sieve Analyses Sieve analyses were performed on selected samples in general accordance with ASTM D 422 to determine the sample grain size distribution. The wet sieve analysis method was used to determine the percentage of soil greater than the U.S. No. 200 mesh sieve. The results of the sieve analyses were plotted, classified in general accordance with the Unified Soil Classification System (USCS), and are presented in Figure B-1. It should be noted that the sieve analyses were performed on soils obtained from samplers that have an opening size of 1½ inches so larger sized particles can’t be obtained by the samplers. Therefore, the sieve results do not account for soil particles that are larger than 1½ inches. Soils with larger sized materials are described in this report qualitatively based on visual observations and experience on projects where excavations were made into similar formations. Atterberg Limits

Atterberg Limit Tests were performed on selected samples in general accordance with ASTM Test Method D 4318 (includes organic determination). The test was used to classify the soil as well as to evaluate index properties. The liquid limit and the plastic limit were estimated through a procedure performed in general accordance with ASTM D 4318. The results of the Atterberg limits testing are summarized in Figures B-2 and B-3.

APPENDIX D Report Limitations and Guidelines for Use

REDMOND CENTRAL CONNECTOR  Redmond, Washington

APPENDIX D REPORT LIMITATIONS AND GUIDELINES FOR USE1 This appendix provides information to help you manage your risks with respect to the use of this report.

Geotechnical Services Are Performed for Specific Purposes, Persons and Projects This report has been prepared for the exclusive use of the City of Redmond, The Berger Partnership PS and other project team members for the Redmond Central Connector (RCC) project. This report is not intended for use by others, and the information contained herein is not applicable to other sites. GeoEngineers structures our services to meet the specific needs of our clients. For example, a geotechnical or geologic study conducted for a civil engineer or architect may not fulfill the needs of a construction contractor or even another civil engineer or architect that are involved in the same project. Because each geotechnical or geologic study is unique, each geotechnical engineering or geologic report is unique, prepared solely for the specific client and project site. Our report is prepared for the exclusive use of our Client. No other party may rely on the product of our services unless we agree in advance to such reliance in writing. This is to provide our firm with reasonable protection against open-ended liability claims by third parties with whom there would otherwise be no contractual limits to their actions. Within the limitations of scope, schedule and budget, our services have been executed in accordance with our Agreement with the Client and generally accepted geotechnical practices in this area at the time this report was prepared. This report should not be applied for any purpose or project except the one originally contemplated.

A Geotechnical Engineering or Geologic Report Is Based on a Unique Set of Projectspecific Factors This report has been prepared for the RCC project in Redmond, Washington. GeoEngineers considered a number of unique, project-specific factors when establishing the scope of services for this project and report. Unless GeoEngineers specifically indicates otherwise, do not rely on this report if it was:

■ not prepared for you; ■ not prepared for your project; ■ not prepared for the specific site explored; or ■ completed before important project changes were made.

Developed based on material provided by ASFE, Professional Firms Practicing in the Geosciences; www.asfe.org .

March 13, 2012 | Page D-1 File No. 0500-172-01

REDMOND CENTRAL CONNECTOR  Redmond, Washington

For example, changes that can affect the applicability of this report include those that affect:

■ the function of the proposed structure; ■ elevation, configuration, location, orientation or weight of the proposed structure; ■ composition of the design team; or ■ project ownership. If important changes are made after the date of this report, GeoEngineers should be given the opportunity to review our interpretations and recommendations and provide written modifications or confirmation, as appropriate.

Subsurface Conditions Can Change This geotechnical or geologic report is based on conditions that existed at the time the study was performed. The findings and conclusions of this report may be affected by the passage of time, by manmade events such as construction on or adjacent to the site, or by natural events such as floods, earthquakes, slope instability or groundwater fluctuations. Always contact GeoEngineers before applying a report to determine if it remains applicable.

Most Geotechnical and Geologic Findings Are Professional Opinions Our interpretations of subsurface conditions are based on field observations from widely spaced sampling locations at the site. Site exploration identifies subsurface conditions only at those points where subsurface tests are conducted or samples are taken. GeoEngineers reviewed field and laboratory data and then applied our professional judgment to render an opinion about subsurface conditions throughout the site. Actual subsurface conditions may differ, sometimes significantly, from those indicated in this report. Our report, conclusions and interpretations should not be construed as a warranty of the subsurface conditions.

Geotechnical Engineering Report Recommendations Are Not Final Do not over-rely on the preliminary construction recommendations included in this report. These recommendations are not final, because they were developed principally from GeoEngineers’ professional judgment and opinion. GeoEngineers’ recommendations can be finalized only by observing actual subsurface conditions revealed during construction. GeoEngineers cannot assume responsibility or liability for this report's recommendations if we do not perform construction observation. Sufficient monitoring, testing and consultation by GeoEngineers should be provided during construction to confirm that the conditions encountered are consistent with those indicated by the explorations, to provide recommendations for design changes should the conditions revealed during the work differ from those anticipated, and to evaluate whether or not earthwork activities are completed in accordance with our recommendations. Retaining GeoEngineers for construction observation for this project is the most effective method of managing the risks associated with unanticipated conditions.

A Geotechnical Engineering or Geologic Report Could Be Subject to Misinterpretation Misinterpretation of this report by other design team members can result in costly problems. You could lower that risk by having GeoEngineers confer with appropriate members of the design team after submitting the report. Also retain GeoEngineers to review pertinent elements of the design team's plans and specifications. Contractors can also misinterpret a geotechnical engineering or geologic report. Reduce that risk by having GeoEngineers participate in pre-bid and preconstruction conferences, and by providing construction observation.

Do Not Redraw the Exploration Logs Geotechnical engineers and geologists prepare final boring and testing logs based upon their interpretation of field logs and laboratory data. To prevent errors or omissions, the logs included in a geotechnical engineering or geologic report should never be redrawn for inclusion in architectural or other design drawings. Only photographic or electronic reproduction is acceptable, but recognize that separating logs from the report can elevate risk.

Give Contractors a Complete Report and Guidance Some owners and design professionals believe they can make contractors liable for unanticipated subsurface conditions by limiting what they provide for bid preparation. To help prevent costly problems, give contractors the complete geotechnical engineering or geologic report, but preface it with a clearly written letter of transmittal. In that letter, advise contractors that the report was not prepared for purposes of bid development and that the report's accuracy is limited; encourage them to confer with GeoEngineers and/or to conduct additional study to obtain the specific types of information they need or prefer. A pre-bid conference can also be valuable. Be sure contractors have sufficient time to perform additional study. Only then might an owner be in a position to give contractors the best information available, while requiring them to at least share the financial responsibilities stemming from unanticipated conditions. Further, a contingency for unanticipated conditions should be included in your project budget and schedule.

Contractors Are Responsible for Site Safety on Their Own Construction Projects Our geotechnical recommendations are not intended to direct the contractor’s procedures, methods, schedule or management of the work site. The contractor is solely responsible for job site safety and for managing construction operations to minimize risks to on-site personnel and to adjacent properties.

Read These Provisions Closely Some clients, design professionals and contractors may not recognize that the geoscience practices (geotechnical engineering or geology) are far less exact than other engineering and natural science disciplines. This lack of understanding can create unrealistic expectations that could lead to disappointments, claims and disputes. GeoEngineers includes these explanatory “limitations” provisions in our reports to help reduce such risks. Please confer with GeoEngineers if you are unclear how these “Report Limitations and Guidelines for Use” apply to your project or site.

Geotechnical, Geologic and Environmental Reports Should Not Be Interchanged The equipment, techniques and personnel used to perform an environmental study differ significantly from those used to perform a geotechnical or geologic study and vice versa. For that reason, a geotechnical engineering or geologic report does not usually relate any environmental findings, conclusions or recommendations; e.g., about the likelihood of encountering underground storage tanks or regulated contaminants. Similarly, environmental reports are not used to address geotechnical or geologic concerns regarding a specific project.

Biological Pollutants GeoEngineers’ Scope of Work specifically excludes the investigation, detection, prevention or assessment of the presence of Biological Pollutants. Accordingly, this report does not include any interpretations, recommendations, findings, or conclusions regarding the detecting, assessing, preventing or abating of Biological Pollutants and no conclusions or inferences should be drawn regarding Biological Pollutants, as they may relate to this project. The term “Biological Pollutants” includes, but is not limited to, molds, fungi, spores, bacteria, and viruses, and/or any of their byproducts. If Client desires these specialized services, they should be obtained from a consultant who offers services in this specialized field.

EXAMPLE TEXT This Stormwater Pollution Prevention Plan (SWPPP) has been prepared as part of the NPDES stormwater permit requirements for the Riverside Heights construction project in Yakima, Washington. The site is located on the north side of Yakima, southwest of the interchange for Interstate 82 (I-82) and State Route 12 (Hwy 12). The existing site is a 2.3-acre lot with a 10,000 square foot one-story apartment building. The proposed development consists of the construction of a new apartment building complex that will include 48 residential units, a swimming pool, underground parking lot, stormwater detention facility, and landscaping. Construction activities will include demolition, excavation, grading, relocation of onsite services/utilities, a poured concrete underground garage and indoor swimming pool complex, and construction of a three-story wood frame building. The purpose of this SWPPP is to describe the proposed construction activities and all temporary and permanent erosion and

Stormwater Pollution Prevention Plan

sediment control (TESC) measures, pollution prevention measures, inspection/monitoring activities, and recordkeeping that will be implemented during the proposed construction project. The objectives of the SWPPP are to: 1.

Implement Best Management Practices (BMPs) to prevent erosion and sedimentation, and to identify, reduce, eliminate or prevent stormwater contamination and water pollution from construction activity.

Prevent violations of surface water quality, ground water quality, or sediment management standards.

Prevent, during the construction phase, adverse water quality impacts including impacts on beneficial uses of the receiving water by controlling peak flow rates and volumes of stormwater runoff at the Permittee’s outfalls and downstream of the outfalls.

This SWPPP was prepared using the Ecology SWPPP Template downloaded from the Ecology website on July 2, 2005. This SWPPP was prepared based on the requirements set forth in the Construction Stormwater General Permit, Stormwater Management Manual for Western Washington (SWMMWW 2005) and in the Stormwater Management Manual for Eastern Washington (SWMMEW 2004). The report is divided into seven main sections with several appendices that include stormwater related reference materials. The topics presented in the each of the main sections are:

Section 1 – INTRODUCTION. This section provides a summary description of the project, and the organization of the SWPPP document.

Section 2 – SITE DESCRIPTION. This section provides a detailed description of the existing site conditions, proposed construction activities, and calculated stormwater flow rates for existing conditions and post– construction conditions.

Section 6 – INSPECTION AND MONITORING. This section provides a description of the inspection and monitoring requirements such as the parameters of concern to be monitored, sample locations, sample frequencies, and sampling methods for all stormwater discharge locations from the site.

Section 7 – RECORDKEEPING. This section describes the requirements for documentation of the BMP implementation, site inspections, monitoring results, and changes to the implementation of certain BMPs due to site factors experienced during construction.

Supporting documentation and standard forms are provided in the following Appendices: Appendix A – Site plans Appendix B – Construction BMPs Appendix C – Alternative Construction BMP list Appendix D – General Permit Appendix E – Site Log and Inspection Forms Appendix F – Engineering Calculations REQUIRED TEXT This Stormwater Pollution Prevention Plan (SWPPP) has been prepared for the City of Redmond – Redmond Central Connector (RCC) Project located in the downtown district along the vacated BNSF right-of-way corridor from Sammamish River Trail to Bear Creek Trail, Redmond, WA 98052. The existing site is the abandoned BNSF rail corridor purchased from the City of Redmond to establish a linear park and multi-modal path across downtown Redmond. This corridor passes through a variety of zoning areas, from natural landscapes to residential and commercial retail. The site is generally flat with little vegetation due to construction of the Stormwater Trunkline. Although the majority of the site currently infiltrates, there are ditches located at the north side of NE 76th Street which connect to storm sewers and catch basins along NE 76th Street. The Central Connector will be located directly above the newly completed Downtown Stormwater Trunkline from Redmond Way to 170th Avenue NE. Proposed stormwater connection to the trunkline will be made at multiple locations along the corridor.

The proposed development consists of the first phase of the RCC, which is a 1.1 mile regional trail that runs through downtown Redmond connecting the Sammamish River Trail to the Bear Creek Trail. See Figure 1 Vicinity Map in Appendix A. This corridor will be designed as a multi-modal trail for shared used by both cyclists and pedestrians. This initial phase of the trail will pass through five roadway intersections and is adjacent to various commercial, mixed-use

Stormwater Pollution Prevention Plan

retail and residential land use zones, and natural wetlands near the connection to the existing Bear Creek Trail. Construction activities will include: • Installing a 12-foot asphalt and cement concrete multi-modal regional trail • Installing concrete landscape elements along the corridor • Excavating and constructing embankments and landforms • Installing gravity block walls • Installing bioretention planters • Installing cement concrete sidewalk, curb and gutter at four (4) intersections • Installing a Rectangular Rapid Flash Beacon (RRFB) at Leary Way • Installing 1 new traffic signal at NE 76th Street and 170th Avenue NE • Paving with hot mix asphalt • Planting trees and shrubs • Installing lawn • Installing irrigation between 161st Avenue NE and Leary Way • Adjusting surface utilities to grade The purpose of this SWPPP is to describe the proposed construction activities and all temporary and permanent erosion and sediment control (TESC) measures, pollution prevention measures, inspection/monitoring activities, and recordkeeping that will be implemented during the proposed construction project. The objectives of the SWPPP are to: 1.

Implement Best Management Practices (BMPs) to prevent erosion and sedimentation, and to identify, reduce, eliminate or prevent stormwater contamination and water pollution from construction activity.

Prevent violations of surface water quality, ground water quality, or sediment management standards.

This SWPPP was prepared using the Ecology SWPPP Template downloaded from the Ecology website. This SWPPP was prepared based on the requirements set forth in the Construction Stormwater General Permit.

2.0 Site Description INSTRUCTIONS

2.1

The following section requires site specific information such as a description of the site area, topography, proposed construction activities and anticipated stormwater runoff flows from the site.

This section is not as automated as some of the other sections of this SWPPP template and will require significant text input from the applicant into the “Required Text” box. Example text is provided.

The example text provided below is specific to a different site and should not simply be copied and reused, but may be copied into the “Required Text” area and then edited as necessary.

The grey shaded text boxes require text inserts. Click the text box to highlight the ENTIRE grey area, then type in text.

Existing Conditions

INSTRUCTIONS

Read the example text, copy relevant text, and edit to suit the specific characteristics of the site.

The recommended format includes 3 paragraphs that cover the mandatory information as follows:

Description of site (location, size, existing structures, topography, typical soil and groundwater characteristics).

Description of drainage (onsite runoff conveyance and downstream receiving water bodies and drainage systems).

Description of critical areas (high erosion risk areas, wetland/stream/shoreline areas, steep slope areas, and landslideprone areas)

The applicant may use their own format for this section, but must include all of the required information described above.

Stormwater Pollution Prevention Plan

EXAMPLE TEXT The proposed site is located just south of Interstate 5 (I-5) and west of Meridian Street in Bellingham, Washington. A site vicinity map and coordinates are provided in Appendix A. The site is 3.5 acres in size and includes a one-story industrial warehouse on the north side of the site, and large gravel parking lot on the south side of the site. The topography of the site and surrounding properties gently slopes to the northwest. Surficial soils consist of 3 feet of silty sandy loam underlain by a deep layer of sands and gravels. The site is well drained and groundwater lies approximately 15 feet below the surface. Runoff from the site generally drains from south to north to a series of catch basins. The catch basins convey runoff to a storm drain system that flows to the northwest corner of the site and discharges to a city owned storm drain system. The city system discharges to Squalicum Creek. At the point of discharge, Squalicum Creek is listed as a Category 5 polluted water of the state under the Stateâ&#x20AC;&#x2122;s Clean Water Act Section 303(d) list, due to zinc and fecal coliform bacteria contamination. There are no critical areas on the site such as high erosion risk areas, wetlands, streams, or steep slopes (potential landslide area). There is a wetland and stream approximately 400 feet north of the site (Squalicum Creek and surrounding riparian habitat). REQUIRED TEXT The first phase of the RCC focuses on the 1.1 mile regional trail that runs through downtown Redmond connecting the Sammamish River Trail to the Bear Creek Trail. See Figure 1 Vicinity Map. This corridor will be designed as a multi-modal trail for shared used by both cyclists and pedestrians. This initial phase of the trail will pass through five roadway intersections and is adjacent to various commercial, mixed-use retail and residential land use zones, and natural wetlands near the connection to the existing Bear Creek Trail. The RCC corridor runs through the abandoned BNSF right-of-way purchased by the City of Redmond. The typical corridor is generally between 50ft and 130ft wide with variations at the proposed plaza locations. The site is generally flat, with steeper slopes along the existing railroad embankement at the west end of the project. The soils are generally recessional outwash with relatively clean sand and gravel. Temporary erosion protection should be used and maintained in areas with exposed or disturbed soils to help reduce the potential for erosion and reduce transport of sediment to adjacent areas This RCC project is within the Cityâ&#x20AC;&#x2122;s Wellhead protection zones 1 and 2 as shown in the City Wellhead Zone map. Part of the City of Redmond potable water supply is pumped from the shallow aquifer beneath these areas of the City. To recharge the aquifer, the City encourages infiltration techniques for runoff from non-pollution generating surfaces (non-PGIS). The Stormwater Trunkline project, currently under construction through the RCC corridor, will serve as a high flow bypass for the City Center drainage basins and will serve as an overflow

Stormwater Pollution Prevention Plan

connection for the RCC or connected adjacent parcel rooftop runoff that is not completely infiltrated. The site predominately infiltrates but also contains an existing storm drain system that gravity flows to the City’s storm system on NE 76th Street, which drain to the Sammamish River located within ¼ mile of the site. At the point of discharge, the Sammamish River is listed as a Category 5 polluted water of the state under the State’s Clean Water Act Section 303(d) list, due to oxygen and a Category 2 due to temperature. On the east end of the project, between 170th Ave NE and the Bear Creek Trail connection, the trail passes through and existing wetland. The proposed trail will be constructed on top of the existing railroad embankment. There are no other critical areas on the site such as high erosion risk areas, streams, or steep slopes (potential landslide area).

2.2

Proposed Construction Activities

INSTRUCTIONS

Similar to the previous section, read the example text, copy relevant text, and edit to suit the specific characteristics of the site.

The recommended format includes the 4 paragraphs shown and the table format showing total site area, proposed area of disturbance, pervious areas, impervious areas, and anticipated runoff flows. The four paragraphs include the following mandatory information:

Description of site development

Description of construction activities (site preparation, demolition, excavation, etc…)

Description of site drainage

Description of final site soil stabilization, revegetation, etc…

The applicant may use their own format for this section, but must include all of the required information described above.

Stormwater Pollution Prevention Plan

EXAMPLE TEXT The proposed development includes the construction of a two-story commercial building that will be used as a storage and retail area for automotive parts and accessories. The proposed building will be centrally located on the site with a new asphalt paved parking lot on the front (north) and a paved loading dock area on the south. A combined stormwater detention and treatment vault will be constructed in the northwest corner (low drainage spot) of the site. New sanitary, electrical, gas, and storm drain utilities will also be constructed. Construction activities will include site preparation, TESC installation, demolition of the existing warehouse structure, excavation for the building foundations and pre-cast concrete stormwater vault, poured concrete foundations, concrete tilt-up building construction, site-wide grading, and asphalt paving. The schedule and phasing of BMPs during construction is provided in Section 4.0. INSTRUCTIONS

For stormwater design information for Western Washington, refer to the SWMMWW for hydraulic analysis and design. The web link is: http://www.ecy.wa.gov/biblio/0510031.html.

For stormwater design information for Eastern Washington, refer to the SWMMEW for hydraulic analysis and design: The web link is: http://www.ecy.wa.gov/biblio/0410076.html.

Stormwater runoff volumes were calculated using the Western Washington Hydrology Model (WWHM). The temporary sedimentation pond that will be used during construction was designed using the 2-year storm event since construction will not occur over a long time-frame (approximately one year). The combined detention and treatment vault was designed using WWHM where the treatment sump was sized using the 6-month treatment volume and the live storage detention volume was designed by matching pre and post construction flows and durations for 50 percent of the 2-year flow and the 50-year flow. After the building is constructed and all new utilities are installed, the site will be graded and paved. A landscape buffer area will be constructed on the north side of the site and the parking area will contain median lane divide planters. The following summarizes details regarding site areas:

The schedule and phasing of BMPs during construction is provided in Section 4.0. Stormwater runoff volumes were calculated using the Western Washington Hydrology Model (WWHM). The general goal for stormwater management within the RCC is to integrate the rainwater collection, transportation and infiltration within the corridor urban design features to the extent possible. Since the water collected through the onsite LID facilities would be limited to nonPGIS area, infiltration can be provided without additional treatment requirements. Any rain gardens that capture and treat runoff from PGIS areas will be lined facilities with all treated water connected to the downstream conveyance system. For the collected water from adjacent parcel rooftop areas, the water would flow from the rooftop downpipe either through shallow piped conveyance or through a decorative swale into the RCC corridor. The water from the adjacent rooftop could also be captured in a rainwater cistern or elevated water feature adjacent to or within the RCC right-of-way. The collected runoff could then flow through a visible art installation or flow to the nearest LID facility. The onsite runoff is collected to a integrated water feature or allows sheet flow to a LID facility. After the collection point, the water would be directed to one or more LID facilities. Overflow from any of the initial LID facilities will connect to the nearest infiltration pipe. Runoff that exceeds the capacity of the infiltration pipe connects to the regional bypass Stormwater Trunkline that runs through most the RCC corridor.

3.0 Construction Stormwater BMPs INSTRUCTIONS

This section mostly consists of pre-programmed text inserted into the document based on input from the Wizard. Some required text such as a brief description of locations and scheduling of BMPs that were chosen in the SWPPP Wizard.

BMPs chosen in the Wizard will automatically appear in the SWPPP text.

Unselected BMPs will automatically be inserted into Appendix C as alternative BMPs that can be referenced at a later date if the selected BMPs are not performing as intended or if site conditions change, warranting implementation of different BMPs than included in the original SWPPP.

A list of BMPs selected in the Wizard is generated in Appendix B. The applicant should photocopy and place the corresponding Ecology fact sheets into Appendix B for each BMP. The Fact sheets can be found in the SWMMWW Volume II Chapter 4 Section 4.1 http://www.ecy.wa.gov/biblio/0510030.html, or the SWMMEW Chapter 7 Section 7.3.1 http://www.ecy.wa.gov/biblio/0410076.html. These fact sheets include specifications and installation requirements for each BMP. Each of the 12 elements described below must be included in the SWPPP, unless it can be justified that a particular element does not apply for the project site, in which case a brief narrative providing the justification must be written and included in the SWPPP. Depending on the site, multiple BMPs for each element may be needed.

The SWPPP preparer should be thoroughly familiar with BMP C160: Certified Erosion and Sediment Control Lead and BMP C161: Payment of Erosion Control Work before completing this section of the SWPPP, because those BMPs are referenced throughout the discussion of BMP selection in this section.

3.1

The 12 BMP Elements

3.1.1

Element #1 â&#x20AC;&#x201C; Mark Clearing Limits

To protect adjacent properties and to reduce the area of soil exposed to construction, the limits of construction will be clearly marked before land-disturbing activities begin. Trees that are to be preserved, as well as all sensitive areas and their buffers, shall be clearly delineated, both in the 15

Stormwater Pollution Prevention Plan

field and on the plans. In general, natural vegetation and native topsoil shall be retained in an undisturbed state to the maximum extent possible. The BMPs relevant to marking the clearing limits that will be applied for this project include: Preserving Natural Vegetation (BMP C101) Buffer Zones (BMP C102) High Visibility Plastic or Metal Fence (BMP C103) Stake and Wire Fence (BMP C104) Alternative BMP not included in the SWMMWW (2005) or SWMMEW (2004) INSTRUCTIONS

Provide a detailed description of the alternative BMP in the required text box below. Describe where, when, and how it will be applied to the site. If applicable, provide a drawing of the BMP in Appendix C. Start the text as â&#x20AC;&#x153;An alternative BMP includes . . . . . . .â&#x20AC;?

REQUIRED TEXT

INSTRUCTIONS

Provide a detailed description for each selected BMP where and when the BMP will be implemented.

REQUIRED TEXT

Alternate BMPs for marking clearing limits are included in Appendix C as a quick reference tool for the onsite inspector in the event the BMP(s) listed above are deemed ineffective or inappropriate during construction to satisfy the requirements set forth in the General NPDES Permit (Appendix D). To avoid potential erosion and sediment control issues that may cause a violation(s) of the NPDES Construction Stormwater permit (as provided in Appendix D), the Certified Erosion and Sediment Control Lead will promptly initiate the implementation of one or more of the alternative BMPs listed in Appendix C after the first sign that existing BMPs are ineffective or failing.

Element #2 – Establish Construction Access

Construction access or activities occurring on unpaved areas shall be minimized, yet where necessary, access points shall be stabilized to minimize the tracking of sediment onto public roads, and wheel washing, street sweeping, and street cleaning shall be employed to prevent sediment from entering state waters. All wash wastewater shall be controlled on site. The specific BMPs related to establishing construction access that will be used on this project include: Stabilized Construction Entrance (BMP C105) Wheel Wash (BMP C106) Construction Road/Parking Area Stabilization (BMP C107) Water Bars (BMP C203) may also be applicable.

Stormwater Pollution Prevention Plan

NPDES Construction Stormwater permit (as provided in Appendix D), the Certified Erosion and Sediment Control Lead will promptly initiate the implementation of one or more of the alternative BMPs listed in Appendix C after the first sign that existing BMPs are ineffective or failing. In addition, sediment will be removed from paved areas in and adjacent to construction work areas manually or using mechanical sweepers, as needed, to minimize tracking of sediments on vehicle tires away from the site and to minimize washoff of sediments from adjacent streets in runoff. Whenever possible, sediment laden water shall be discharged into onsite, relatively level, vegetated areas (BMP C240 paragraph 5, page 4-102). In some cases, sediment discharge in concentrated runoff can be controlled using permanent stormwater BMPs (e.g., infiltration swales, ponds, trenches). Sediment loads can limit the effectiveness of some permanent stormwater BMPs, such as those used for infiltration or biofiltration; however, those BMPs designed to remove solids by settling (wet ponds or detention ponds) can be used during the construction phase. When permanent stormwater BMPs will be used to control sediment discharge during construction, the structure will be protected from excessive sedimentation with adequate erosion and sediment control BMPs. Any accumulated sediment shall be removed after construction is complete and the permanent stormwater BMP will be restabilized with vegetation per applicable design requirements once the remainder of the site has been stabilized. INSTRUCTIONS

The following text includes more complex sediment control/treatment BMPs. These BMPs should be used if sediment controls are not (or not anticipated to be) adequate for the site-specific construction activities. These BMPs are primarily used on:

Larger sites (i.e. greater than 5 acres), or,

Sites that have continual soil disturbance and are difficult to temporarily stabilize, or,

Sites at higher risk of erosion (i.e. slopes), or,

Sites where the downstream environment is particularly sensitive and more stringent discharge controls are required.

On larger, more complex sites, it is recommended to have these BMPs as possible contingencies if turbidity is determined to be an issue during construction. The order of the BMPs presented is from least to most

Stormwater Pollution Prevention Plan

complex and involved. A typical approach to these BMPs is to use the sediment pond approach first, then move to filtration or chemical treatment. This approach can be added to the text provided below if applicable.

It is recommended that these BMPs are considered, or sequentially implemented, in the order shown below in the event that more stringent sediment controls are deemed necessary based on either anticipated sediment control issues or onsite monitoring/inspection. Implementation of BMP C250 is complex. Chemical Treatment requires written approval from Ecology prior to implementation (see BMP C250 fact sheet in the SWMMWW (2005)) and needs to be specifically written into the permit.

The following BMPs will be implemented as end-of-pipe sediment controls as required to meet permitted turbidity limits in the site discharge(s). Prior to the implementation of these technologies, sediment sources and erosion control and soil stabilization BMP efforts will be maximized to reduce the need for end-of-pipe sedimentation controls.

The project site is located east of the Cascade Mountain Crest. As such, all temporary on-site conveyance channels shall be designed, constructed, and stabilized to prevent erosion from the expected peak flow velocity of a 2-year, 24-hour recurrence interval storm for the developed condition. Stabilization, including armoring material, adequate to prevent erosion of outlets, adjacent streambanks, slopes, and downstream reaches shall be provided at the outlets of all conveyance systems. 3.1.9 Element #9 â&#x20AC;&#x201C; Control Pollutants â&#x20AC;&#x201C; Spill Prevention, Control, and Countermeasure (SPCC) Plan (Appendix G) This section supplements the SPCC Plan in Appendix G. All pollutants, including waste materials and demolition debris, that occur onsite shall be handled and disposed of in a manner that does not cause contamination of stormwater. Good housekeeping and preventative measures will be taken to ensure that the site will be kept clean, well organized, and free of debris. If required, BMPs to be implemented to control specific sources of pollutants are discussed below. Vehicles, construction equipment, and/or petroleum product storage/dispensing:

All vehicles, equipment, and petroleum product storage/dispensing areas will be inspected regularly to detect any leaks or spills, and to identify maintenance needs to prevent leaks or spills.

On-site fueling tanks and petroleum product storage containers shall include secondary containment.

Spill prevention measures, such as drip pans, will be used when conducting maintenance and repair of vehicles or equipment.

In order to perform emergency repairs on site, temporary plastic will be placed beneath and, if raining, over the vehicle.

Contaminated surfaces shall be cleaned immediately following any discharge or spill incident.

Demolition:

Dust released from demolished sidewalks, buildings, or structures will be controlled using Dust Control measures (BMP C140) and contained. Non-hazardous runoff from dust control will be filtered using listed BMPâ&#x20AC;&#x2122;s to avoid getting into the storm system and infiltrating into unpaved areas.

Stormwater Pollution Prevention Plan

Storm drain inlets vulnerable to stormwater discharge carrying dust, soil, or debris will be protected using Storm Drain Inlet Protection (BMP above for Element 7).

Process water and slurry resulting from sawcutting and surfacing operations will be prevented from entering the waters of the State by implementing Sawcutting and Surfacing Pollution Prevention measures (BMP C152).

Excavation and tunneling spoils dewatering waste:

Dewatering BMPs and BMPs specific to the excavation and tunneling (including handling of contaminated soils) are discussed under Element 10.

Concrete and grout:

Process water and slurry resulting from concrete work will be prevented from entering the waters of the State by implementing Concrete Handling measures (BMP C151).

Other BMPs will be administered as necessary to address any additional pollutant sources on site.

3.1.10 Element #10 â&#x20AC;&#x201C; Control Dewatering All dewatering water from open cut excavation, tunneling, foundation work, trench, or underground vaults shall be discharged into a controlled conveyance system prior to discharge to a sediment trap or sediment pond. Channels will be stabilized, per Element #8. Clean, nonturbid dewatering water will not be routed through stormwater sediment ponds, and will be discharged to systems tributary to the receiving waters of the State in a manner that does not cause erosion, flooding, or a violation of State water quality standards in the receiving water. Highly turbid dewatering water from soils known or suspected to be contaminated, or from use of construction equipment, will require additional monitoring and treatment as required for the specific pollutants based on the receiving waters into which the discharge is occurring. Such monitoring is the responsibility of the contractor. However, the dewatering of soils known to be free of contamination will trigger BMPs to trap sediment and reduce turbidity. At a minimum, geotextile fabric socks/bags/cells will be used to filter this material. Other BMPs to be used for sediment trapping and turbidity reduction include the following:

All temporary erosion and sediment control BMPs shall be removed within 30 days after the final site stabilization is achieved or after the temporary BMPs are no longer needed. Trapped sediment shall be removed or stabilized on site. Disturbed soil resulting from removal of BMPs or vegetation shall be permanently stabilized. 3.1.12 Element #12 â&#x20AC;&#x201C; Manage the Project Erosion and sediment control BMPs for this project have been designed based on the following principles:

Design the project to fit the existing topography, soils, and drainage patterns.

Emphasize erosion control rather than sediment control.

Minimize the extent and duration of the area exposed.

Keep runoff velocities low.

Retain sediment on site.

Thoroughly monitor site and maintain all ESC measures.

Schedule major earthwork during the dry season.

In addition, project management will incorporate the key components listed below: As this project site is located west of the Cascade Mountain Crest, the project will be managed according to the following key project components: Phasing of Construction

The construction project is being phased to the extent practicable in order to prevent soil erosion, and, to the maximum extent possible, the transport of sediment from the site during construction.

Revegetation of exposed areas and maintenance of that vegetation shall be an integral part of the clearing activities during each phase of construction, per the Scheduling BMP (C 162).

Seasonal Work Limitations

From October 1 through April 30, clearing, grading, and other soil disturbing activities shall only be permitted if shown to the satisfaction of

Stormwater Pollution Prevention Plan

the local permitting authority that silt-laden runoff will be prevented from leaving the site through a combination of the following:

Site conditions including existing vegetative coverage, slope, soil type, and proximity to receiving waters; and

Limitations on activities and the extent of disturbed areas; and

Proposed erosion and sediment control measures.

Based on the information provided and/or local weather conditions, the local permitting authority may expand or restrict the seasonal limitation on site disturbance.

The following activities are exempt from the seasonal clearing and grading limitations:

Routine maintenance and necessary repair of erosion and sediment control BMPs;

Routine maintenance of public facilities or existing utility structures that do not expose the soil or result in the removal of the vegetative cover to soil; and

Activities where there is 100 percent infiltration of surface water runoff within the site in approved and installed erosion and sediment control facilities.

Coordination with Utilities and Other Jurisdictions

Care has been taken to coordinate with utilities, other construction projects, and the local jurisdiction in preparing this SWPPP and scheduling the construction work.

Inspection and Monitoring

All BMPs shall be inspected, maintained, and repaired as needed to assure continued performance of their intended function. Site inspections shall be conducted by a person who is knowledgeable in the principles and practices of erosion and sediment control. This person has the necessary skills to:

Assess the site conditions and construction activities that could impact the quality of stormwater, and

Stormwater Pollution Prevention Plan

Assess the effectiveness of erosion and sediment control measures used to control the quality of stormwater discharges.

A Certified Erosion and Sediment Control Lead shall be on-site or on-call at all times.

Whenever inspection and/or monitoring reveals that the BMPs identified in this SWPPP are inadequate, due to the actual discharge of or potential to discharge a significant amount of any pollutant, appropriate BMPs or design changes shall be implemented as soon as possible.

Maintaining an Updated Construction SWPPP

3.2

This SWPPP shall be retained on-site or within reasonable access to the site.

The SWPPP shall be modified whenever there is a change in the design, construction, operation, or maintenance at the construction site that has, or could have, a significant effect on the discharge of pollutants to waters of the state.

The SWPPP shall be modified if, during inspections or investigations conducted by the owner/operator, or the applicable local or state regulatory authority, it is determined that the SWPPP is ineffective in eliminating or significantly minimizing pollutants in stormwater discharges from the site. The SWPPP shall be modified as necessary to include additional or modified BMPs designed to correct problems identified. Revisions to the SWPPP shall be completed within seven (7) days following the inspection.

6.0 Site Inspections and Monitoring INSTRUCTIONS

Monitoring requirements are based on thresholds for the size of the site and the amount of disturbance that will occur during construction. Below includes standard text and automatically inserted text based on your response to the questions in the Wizard.

For most of this section, there is no required text to be written or selected. The text will be inserted based on your responses to the questions in the SWPPP Wizard.

Make sure all questions were answered in the Wizard.

There may be some required text to be inserted if Ecology has instructed the applicant to perform special monitoring.

Monitoring includes visual inspection, monitoring for water quality parameters of concern, and documentation of the inspection and monitoring findings in a site log book. A site log book will be maintained for all on-site construction activities and will include:

A record of the implementation of the SWPPP and other permit requirements;

Site inspections; and,

Stormwater quality monitoring.

For convenience, the inspection form and water quality monitoring forms included in this SWPPP include the required information for the site log book. This SWPPP may function as the site log book if desired, or the forms may be separated and included in a separate site log book. However, if separated, the site log book but must be maintained on-site or within reasonable access to the site and be made available upon request to Ecology or the local jurisdiction.

6.1

Site Inspection

All BMPs will be inspected, maintained, and repaired as needed to assure continued performance of their intended function. The inspector will be a Certified Erosion and Sediment Control Lead (CESCL) per BMP C160. The name and contact information for the CESCL is provided in Section 5 of this SWPPP.

Stormwater Pollution Prevention Plan

Site inspection will occur in all areas disturbed by construction activities and at all stormwater discharge points. Stormwater will be examined for the presence of suspended sediment, turbidity, discoloration, and oily sheen. The site inspector will evaluate and document the effectiveness of the installed BMPs and determine if it is necessary to repair or replace any of the BMPs to improve the quality of stormwater discharges. All maintenance and repairs will be documented in the site log book or forms provided in this document. All new BMPs or design changes will be documented in the SWPPP as soon as possible. 6.1.1

Site Inspection Frequency

Site inspections will be conducted at least once a week and within 24 hours following any discharge from the site. For sites with temporary stabilization measures, the site inspection frequency can be reduced to once every month. 6.1.2

Site Inspection Documentation

The site inspector will record each site inspection using the site log inspection forms provided in Appendix E. The site inspection log forms may be separated from this SWPPP document, but will be maintained on-site or within reasonable access to the site and be made available upon request to Ecology or the local jurisdiction.

6.2

Stormwater Quality Monitoring

6.2.1

Turbidity Sampling

Monitoring requirements for the proposed project will include either turbidity or water transparency sampling to monitor site discharges for water quality compliance with the 2005 Construction Stormwater General Permit and DOE Letter Dated May 25, 2010 (Appendix D). Sampling will be conducted at all discharge points at least once per calendar week. Turbidity or transparency monitoring will follow the analytical methodologies described in Section S4 of the 2005 Construction Stormwater General Permit (Appendix D). The key benchmark values that require action are 25 NTU for turbidity (equivalent to 32 cm transparency) and 250 NTU for turbidity (equivalent to 6 cm transparency). If the 25 NTU benchmark for turbidity (equivalent to 32 cm transparency) is exceeded, the following steps will be conducted: 1.

Ensure all BMPs specified in this SWPPP are installed and functioning as intended.

Assess whether additional BMPs should be implemented, and document revisions to the SWPPP as necessary.

Stormwater Pollution Prevention Plan

Sample discharge location daily until the analysis results are less than 25 NTU (turbidity) or greater than 32 cm (transparency).

If the turbidity is greater than 25 NTU (or transparency is less than 32 cm) but less than 250 NTU (transparency greater than 6 cm) for more than 3 days, additional treatment BMPs will be implemented within 24 hours of the third consecutive sample that exceeded the benchmark value. Additional treatment BMPs to be considered will include, but are not limited to, off-site treatment, infiltration, filtration and chemical treatment. If the 250 NTU benchmark for turbidity (or less than 6 cm transparency) is exceeded at any time, the following steps will be conducted:

6.2.1

Notify Ecology by phone within 24 hours of analysis (see Section 5.0 of this SWPPP for contact information).

Continue daily sampling until the turbidity is less than 25 NTU (or transparency is greater than 32 cm).

Initiate additional treatment BMPs such as off-site treatment, infiltration, filtration and chemical treatment within 24 hours of the first 250 NTU exceedance.

Implement additional treatment BMPs as soon as possible, but within 7 days of the first 250 NTU exceedance.

Describe inspection results and remedial actions taken in the site log book and in monthly discharge monitoring reports as described in Section 7.0 of this SWPPP.

Turbidity Sampling

Additional monitoring requirements may apply for: 1) discharges to 303( d) listed waterbodies and waterbodies with applicable TMDLs for turbidity, fine sediment, high pH, or phosphorus - see Condition S8; and 2) sites required to perform additional monitoring by Ecology order - see Condition G 13.

D. pH Monitoring: Sites with Significant Concrete Work or Engineered Soils

Stormwater Pollution Prevention Plan

Beginning October I, 2006, if construction activity will result in the disturbance of 1 acre or more, and involves significant concrete work or the use of engineered soils, and storm water from the affected area drains to surface waters of the state or to a storm sewer system that drains to surface waters of the state, the Permittee shall conduct pH monitoring as set forth below: 1. For sites with significant concrete work, the pH monitoring period shall commence when the concrete is first exposed to precipitation and continue weekly until stormwater pH is 8.5 or less. a. "Significant concrete work" means greater than 1000 cubic yards poured concrete or recycled concrete. 2. For sites with engineered soils, the pH monitoring period shall commence when the soil amendments are first exposed to precipitation and shall continue until the area of engineered soils is fully stabilized. a. "Engineered soils" means soil amendments including, but not limited, to Portland cement treated base (CTB), cement kiln dust (CKD), or fly ash. 3. During the pH monitoring period, the Permittee shall obtain a representative sample of stormwater and conduct pH analysis at least once per week. 4. The Permittee shall monitor pH in the sediment trap/pond(s) or other locations that receive stormwater runoff from the area of significant concrete work or engineered soils prior to discharge to surface waters. 5. The benchmark value for pH is 8.5 standard units. Any time sampling indicates that pH is 8.5 or greater, the Permittee shall: a. Prevent the high pH water (8.5 or above) from entering storm sewer systems or surface waters; and b. If necessary, adjust or neutralize the high pH water using an appropriate treatment BMP such as CO2 sparging or dry ice. The Permittee shall obtain written approval from Ecology prior to using any form of chemical treatment other than C02 sparging or dry ice. 6. The Permittee shall perform pH analysis on-site with a calibrated pH meter, pH test kit, or wide range pH indicator paper. The Permittee shall record pH monitoring results in the site log book.

Turbidity or transparency monitoring will follow the analytical methodologies described in Section S4 of the 2005 Construction Stormwater General Permit (Appendix D). The key benchmark values that require action are 25 NTU for turbidity (equivalent to 32 cm transparency) and 250 NTU for turbidity (equivalent to 6 cm transparency). If the 25 NTU 47

Stormwater Pollution Prevention Plan

benchmark for turbidity (equivalent to 32 cm transparency) is exceeded, the following steps will be conducted: 1. Ensure all BMPs specified in this SWPPP are installed and functioning as intended. 2. Assess whether additional BMPs should be implemented, and document revisions to the SWPPP as necessary. 3. Sample discharge location daily until the analysis results are less than 25 NTU (turbidity) or greater than 32 cm (transparency). If the turbidity is greater than 25 NTU (or transparency is less than 32 cm) but less than 250 NTU (transparency greater than 6 cm) for more than 3 days, additional treatment BMPs will be implemented within 24 hours of the third consecutive sample that exceeded the benchmark value. Additional treatment BMPs to be considered will include, but are not limited to, off-site treatment, infiltration, filtration and chemical treatment. If the 250 NTU benchmark for turbidity (or less than 6 cm transparency) is exceeded at any time, the following steps will be conducted: 1. Notify Ecology by phone within 24 hours of analysis (see Section 5.0 of this SWPPP for contact information). 2. Continue daily sampling until the turbidity is less than 25 NTU (or transparency is greater than 32 cm). 3. Initiate additional treatment BMPs such as off-site treatment, infiltration, filtration and chemical treatment within 24 hours of the first 250 NTU exceedance. 4. Implement additional treatment BMPs as soon as possible, but within 7 days of the first 250 NTU exceedance. 5. Describe inspection results and remedial actions taken in the site log book and in monthly discharge monitoring reports as described in Section 7.0 of this SWPPP.

Recordkeeping

7.1.1

Site Log Book

A site log book will be maintained for all on-site construction activities and will include:

A record of the implementation of the SWPPP and other permit requirements;

Site inspections; and,

Stormwater quality monitoring.

INSTRUCTIONS

This SWPPP may function as the site log book if the project has minimal monitoring requirements or construction duration is shorter than 2 to 3 months. The appendices can include multiple copies of the blank checklists and inspection forms as needed to supplement for the site log book. This is recommended for smaller, simple construction sites. This is the flexible and depends on the preference of the applicant. If the duration of the project is greater than 2 to 3 months or if there is significant monitoring requirements, it is recommended that a separate site log be maintained incorporating the example forms provided in this SWPPP Template document.

Provide a brief explanation in the â&#x20AC;&#x153;Required Textâ&#x20AC;? box below if the site log book is attached to the SWPPP or maintained in a separate site log book.

For convenience, the inspection form and water quality monitoring forms included in this SWPPP include the required information for the site log book.
