Channel Improvements/Inouye 26 May 1, 2012 Project Number 10-3030C ADDENDUM CONTRACTOR'S QUALIFICATION STATEMENT ' (RCW 39.04.350) THE CITY WILL REVIEW THE CONTRACTOR'S RESPONSES TO THIS FORM TO DETERMINE WHETHER THE BIDDING CONTRACTOR IS RESPONSIBLE TO PERFORM THE CONTRACT WORK. THIS FORM REQUIRES CRITERIA ESTABLISHED BY STATE LAW AS WELL AS SUPPLEMENTAL CRITERIA ESTABLISHED BY THE CITY THAT ARE APPLICABLE TO THIS PUBLIC WORKS PROJECT. THE BIDDER SHOULD READ AND RESPOND TO THIS FORM CAREFULLY. Indicia of contractor's responsibility inherently involve subjective determinations as to the contractor's ability to perform and complete the contract work responsibly and to the owner city's satisfaction. The city has an obligation and a duty to Its citizens and its taxpayers to administer its budgets and complete its projects in a businesslike manner. Accordingly, it has a duty to exercise the type of Inquiry and discretion a business would conduct when selecting a contractor who will be responsible to perform the contract work. The city's supplemental criteria are based, in large part, on the qualification statement form used by the American Institute of Architects. The city provides these criteria so as to provide the most objective framework possible within which the city will make Its decision regarding the bidder's ability to be responsible to perform the contract work. ' These criteria, taken together, will form the basis for the city's decision that a bidder is or is not responsible to perform the contract work. Any bidder may make a formal written request to the city to modify the criteria set forth in this qualification statement, but that request may only be made within 48 hours of the date and time that the bidder first obtains the bid documents or three (3) business days prior to the scheduled bid opening date, whichever occurs first. If the city receives a modification request, it will consider any information submitted in the request and will respond before the bid submittal deadline. If the city's evaluation results in changed criteria, the city will issue an addendum establishing the new or modified criteria. If the city determines that, based on the criteria established in this statement, a bidder is not responsible to perform the contract work, the city will provide written notice of its determination that will include the city's reason for its decision. The bidder has 24 hours from the time the city delivers written notice to the bidder that the bidder is not responsible to perform the contract work to appeal the city's determination. No appeals will be received after the expiration of this 24 hour appeal period. The city may deliver this notice by hand delivery, email, facsimile, or regular mail. In the event the city uses regular mail, the delivery will be deemed complete three days after being placed in the U.S. Mail. The bidder's right to appeal is limited to the single remedy of providing the city with additional information to be considered before the city issues a final determination. Bidder acknowledges and understands that, as provided by RCW 39.04.350, no other appeal is allowed and no other remedy I of any kind or nature is available to the bidding contractor if the City determines that the bidder is not responsible to perform the contract work. 641"Ave S Channel Improvements/Inouye 27 May 1, 2012 Project Number 10-3030C ADDENDUM If the bidder fails to request a modification within the time allowed, or fails to appeal a determination that the bidder is not responsible within the time allowed, the city will make Its determination of bidder responsibility based on the information submitted.

The Contractor shall assume full responsibility for detailed dimensions, elevations, and excavation slopes ' measured from these City furnished stakes and marks. The Contractor shall provide a work site clear of equipment, stockpiles and obstructions which has been prepared and maintained to permit construction staking to proceed in a safe and orderly manner. A City survey crew can stake a finite amount of work in a single day (see Section 1-05.5(6) of the Kent Special Provisions herein). The Contractor shall provide staking requests for a reasonable amount of work to the Engineer at least 3 working days in advance to allow the I survey crew adequate time for setting stakes. If the work site is obstructed so that survey work cannot be done, a new request for work shall be submitted by the Contractor so that the survey can be rescheduled once the site is properly prepared. Up to an additional 3 working days may be required depending on work load, to complete the rescheduled work. Note: A working day is a consecutive eight hour period between 7:00 AM and 6:00 PM, Monday through Friday, except holidays as listed in Section 1-08.4 of the Kent Special Provisions. It is illegal under Revised Code of Washington 58.09.130 and Washington State Administrative Code 332-120 to willfully destroy survey markers. Stakes, marks, and other reference points set by City forces, and existing City, State or Federal monumentation, shall be carefully preserved by the Contractor. The Contractor shall notify the Engineer immediately if it becomes apparent that a survey marker will t be disturbed due to construction. The Contractor will allow ample time for City Survey Department personnel to acquire adequate information so that the monument may be replaced in its original position after construction. If the City is not notified and a stake, marker or monument is disturbed or destroyed the Contractor will be charged at a rate of $150/hr for City Surveyors to replace the stake, marker or 64'Ave S Channel Improvements/Inouye 1 - 9 April 18, 2012 Project Number 10-3030C monument that was not to be disturbed or damaged by the Contractor's operations. This charge will be deducted from monies due or to ' become due to the Contractor. Any claim by the Contractor for extra compensation by reason of alterations or reconstruction work allegedly due to error in the Surveyor's line and grade, will not be allowed unless the original control points set by the Surveyor still exist, or unless other satisfactory substantiating evidence to prove the error is furnished the Surveyor. Three consecutive points set on line or grade shall be the minimum points used to determine any variation from a straight line or grade. ' Any such variation shall, upon discovery, be reported to the Engineer. In the absence of such report the Contractor shall be liable for any error in alignment or grade. 1-05.5(2) Roadway and Utility Surveys The Engineer shall furnish to the Contractor, one time only, all principal lines, grades and measurements the Engineer deems necessary for completion of the work. These shall generally consist of one initial set of: 1. Cut or fill stakes for establishing grade and embankments, 2. Curb or gutter grade stakes, 3. Centerline finish grade stakes for pavement sections wider than 25 feet, and 4. Offset points to establish line and grade for underground utilities such as water, sewers, storm drains, Illumination and signalization. No intermediate stakes shall be provided between curb grade and , centerline stakes. On alley construction projects with minor grade changes, the Engineer ' shall provide offset hubs on one side of the alley to establish the alignment and grade. Alleys with major grade changes shall have embankments staked to establish grade before offset hubs are set. 1-05.5(4) Control Stakes , Stakes that constitute reference points for all construction work will be conspicuously marked with an appropriate color of flagging tape. It will be the responsibility of the Contractor to inform his employees and subcontractors of their importance and of the necessity for their preservation. The Contractor shall determine appropriate construction stake offset distances to prevent damage to stakes by his construction equipment. Should it become necessary, for any reason, to replace these control stakes, the Contractor will be charged at the rate of $150/hr for City Surveyors to replace the stakes. The Contractor may not charge the City for any standby or "down" time as a result of any replacement of control stakes. If the removal of a control stake or monument is 641'Ave S Channel Improvements/Inouye 1 - 10 April 18, 2012 Protect Number 10-3030C required by the construction operations of the Contractor or Its subcontractors, and advance notice of at least two (2) full business days is given to the City, the City will reference, remove, and later replace the stakes or monument at no cost to the Contractor. 1-05.5(5) Staking Services Work requests must be made at least 3 days in advance of the required staking. 1 The City will furnish the following stakes and reference marks: 1. Clearing Limits - One set of clearing limit stakes will be set at I approximately 25 foot stations where needed. 2. Rough Grading - One set of rough grade stakes will be set along the construction centerline of streets at 50 foot stations as required. (If superelevations require intermediate stakes along vertical curves, the City will provide staking at closer intervals.) One set of primary cut and fill stakes will be set for site work. One set of secondary final grade cut and fill stakes will be set where applicable. 3. Storm Sewers - Two cut or fill stakes for each inlet, catch basin or manhole will be set at appropriate offsets to the center of the structure. After installation and back fill, inverts will be checked for correctness. 4. Sanitary Sewers - Two cut or fill stakes for each manhole or cleanout location will be set at appropriate offsets to the center of the structure. After installation and backfill, inverts will be 1 checked for correctness. 5. Water Main - One set of line stakes will be furnished for water mains at 50 foot stations. Additionally, two reference stakes for each valve, hydrant, tee and angle point location will be set concurrently with these line stakes. 6. Staking for Embankments - Catch points and one line stake will be set in those cases where the vertical difference in elevation from the construction centerline to the toe or top of a cut or fill slope exceeds 3 feet. In all other areas, stakes shall be set at an appropriate offset to the street centerline to allow for the preservation of said offsets through the rough grading phase. In both cases the stakes shall be clearly marked with appropriate information necessary to complete the rough grading phase. 7.

Joint manufacturers shall be prepared to meet with the Engineer for discussion of the submitted data. Joints approved for bidding, other than those with prior approval as listed above, will be identified by issuing a letter of approval to the manufacturer. This letter shall be included with any quotes from manufacturers to contractors for the joint in question during the bid preparation. Review and approval will not relieve the contractor of responsibility for proper performance and service of all materials and construction relating to the restraint of unbalanced hydrostatic forces. i i i t i i ' 64th Ave S Channel Improvements/Inouye 9 - 9 April 18, 2012 Project Number 10-3030C KENT STANDARD PLANS The following Kent Standard Plans supplement all other plans, which have been prepared for this project and are considered to be a part of the project plans.

Project Description- Improvement plans call for replacing the two existing channel crossings in the drainage channel that parallels the west side of 641h Avenue S, one at the railroad crossing of 641h Avenue S, and the other at the intersection of S 2261h Street and 64,h Avenue S, Both channel crossings consist of three 60-inch-diameter concrete culverts that will be replaced with either two, 14- foot by 5-foot by 128 feet long (railroad crossing) or two, 10-fcot by 7-foot by 106 feet long(S 226'h Street crossing) segmented concrete box culverts. Exploratory Methods We explored subsurface conditions by means of four borings, two at each drainage channel crossing, advanced through fill and native soils at the anticipated alignment of the Ireplacement culverts The borings were advanced to depths of 20 to 45 feet below existing grade Sod Conditions- Soils along the drainage channel alignment consist of 2 to 11 feet of medium dense, moist to wet, silty sand with some gravel and medium stiff to hard sandy silt with trace to some gravel fill soils Beneath the fill soils are 1 to 3 feet of medium stiff to stiff sandy silt with some organics mantling 17 to 21 feet of very soft to medium stiff silt with trace to some organics (Floodplain Deposits)with interbedded silty sand layers. Beneath the fill and floodplain soils are 5 to 18 feet of loose to medium dense silty fine sand (Alluvial Deposits)with interbeds of sandy silt (Floodplain deposits. At approximately 43 feet below the ground surface, very soft to soft silt with peat seams was encountered, to the full depth of our explorations of 511/2 feet iGroundwater Conditions- Our explorations encountered groundwater in the alluvial deposits ranging from a depth from 23 to 27 feet below ground surface (elevations ranging from 4 to 8 feet) Also, we encountered perched groundwater ranging from a depth of 10 to 15 feet below the ground surface (elevations of 16 to 23 feet) at the approximate level of the surface water in the drainage channel 1 Pavement Conditions- The existing pavement overlying the S 2261h Street culvert crossing appears to be in relatively good condition The pavement did not exhibit any excessive cracking, raveling, settlement or aging Since our borings were advanced adjacent to the pavement section, we were unable to determine the thickness of the pavement section AMEC Environment& Infrastructure, Inc Project No,1-917-17292-0 1 P 117292-0_64th Ave 8—Channel ImprovementslGeoReports164th Ave 5 Eng Rpt DraN 111412 docx I amecl* Liquefaction Our analyses indicate that the loose to medium dense sands and soft to stiff sandy silts have a high susceptibility to liquefaction. Settlement due to liquefaction is estimated to be from 6 to 12 inches - Foundation Considerations: Subsurface and loading conditions vary at the two culvert replacement locations The culvert crossing at S 226" Street has more favorable granular subgrade soils with some soft silt and lower loading due to vehicles than the culvert crossing at the railroad spur which has a much thicker layer of soft silt and is subject to higher, but infrequent railroad loading. At the railroad crossing, the preferred option would be to support the culvert using compacted aggregate I piers Aggregate piers would also have the benefit of mitigating the native sandy soils for liquefaction settlement. If the railroad surcharge loading can be neglected a 2 foot bearing pad of lightweight aggregate fill would be feasible to support the culvert At the S 226th Street crossing, we recommend removal of the soft silt layer and replacement with a 4 foot bearing pad comprised of quarry spalls, Excavation and Temporary Shoring Considerations:We understand that an open cut construction method is the preferred option for culvert replacement If temporary cut slopes cannot be excavated due to site constraints, temporary shoring will be necessary for worker access In our opinion, driven sheet piles would be feasible for the subsurface conditions encountered in our explorations and expected excavation depths Temporary Traffic Considerations. Our reconnaissance disclosed the existing embankment side slopes to consist of relatively loose soil with moderate vegetation If the roadway will not be closed, and if temporary road widening is required for maintaining traffic flow on roadway shoulders, remedial repairs to the outer portion of the existing embankments would likely be required. On-Site Soil Considerations- Because the on-site soils are moisture-sensitive and would be readily disturbed when wet, the contractor should install appropriate temporary drainage systems at the construction site and should minimize traffic over exposed subgrades Ideally, earthwork would be scheduled for the summer and fall months, when drier weather will maximize the potential for reusing on-site soils and when groundwater levels will likely be at their seasonal low 2.0 SITE AND PROJECT DESCRIPTION The project site is located on the west side of 64th Avenue S, from just north of the intersection with S 226th Street to approximately 500 feet south The approximate location of the project site is shown on the enclosed Site Location Map (Figure 1) The project site is comprised of two crossings ofthe drainage channel that parallels the west side of 64`h Avenue S, one the Union Pacific Railroad crossing of 64th Avenue S, and the other at the intersection of S 2261h Street and 64'h Avenue S Both existing channel crossings consist of three 60-inch-diameter concrete culverts with invert elevations of AMEC Environment& Infrastructure, Inc 2 ProleciNo 1-91 7-1 7292-0 P 117292-0_64th Ave S_Channel ImprovemenWGeoReports164th Ave S Eng Rpl Ora(1 111412 docx i i ame& approximately 21 feet the railroad crossing and 22 feet at the 226th Street crossing, with some indication of differential settlement opposite to the northward flow direction.. We understand the protect is to replace the existing concrete culvert pipes at each location with concrete box culverts At the railroad crossing, we understand two side-by-side culverts are planned, each approximately 128 feet long by 14 feet wide by 5 feet high Existing ground surface is approximately elevation 32 feet with the bottom of the proposed culvert footing at approximately elevation 20 feet. At the northern culvert crossing of S. 226th Street, two side-by-side culverts each approximately 106 feet long by 10 feet wide by 7 feel high Existing ground surface is approximately elevation 31 feet with the bottom of the proposed culvert footing at approximately elevation 19 feet. According to the structural engineer, the estimated applied loading at the base of the culvert will be 3,000 pounds per square foot (psf) The enclosed Site and Exploration Plan (Figure 2) illustrates the site boundaries and adjacent existing features The conclusions and recommendations contained in this report are based on our understanding of the currently proposed utilization of the project site, as derived from layout drawings, written information, and verbal information supplied to us. Consequently, if any changes are made in the currently proposed project, we may need to modify our conclusions and recommendations contained herein to J Y reflect those changes 3.0 EXPLORATORY METHODS AMEC explored surface and subsurface conditions at the project site during November 2011. Our exploration and testing program comprised the following elements • A visual surface reconnaissance of the site; • Four borings (designated B-1 through B-4)with Standard Penetration Tests, advanced at strategic locations beneath the culvert replacement locations, • Three gradation analysis, two Atterberg limit tests, four US No 200 Wash gradations, and nine moisture content determinations performed on representative soil samples obtained from beneath the site, and A review of published geologic and seismologic maps and literature. Table 1 summarizes the approximate locations, surface elevations, and termination depths of all pertinent subsurface explorations, and Figure 2 depicts their approximate relative locations. Appendix A of this report includes boring logs and a description of our field exploration procedures, and Appendix B presents laboratory testing procedures and results AMEC Environment&Infrastructure Inc Protect No 1-917.17292-0 3 P 117292-D_64th Ave S Channel ImprovementmGeoRepodM64th Ave S Eng Rpt Draft 111412 dom amec%6 Table 1 Approximate Locations, Elevations, and Depths of Explorations Surface Termination Elevation Depth Exploration Location (feet) (feet) B-01 Channel Station 14+45, 31' Right 312 265 B-02 Channel Station 15+78, 27' Left 312 515 B-03 Channel Station 18+36, 33' Left 31 1 265 B-04 Channel Station 19+72, 38' Left 309 51 5 �I Elevation datum.Topographic survey provided by City of Kent Public Works Department The specific number, locations, and depths of our explorations were selected by AMEC in relation to the existing and proposed site features, under the constraints of surface access, underground utility conflicts, and budget considerations, The relative location of each exploration was determined by a site survey provided by the City of Kent Public Works Department The elevations of each exploration were provided on the site survey. Consequently, the data listed in Table 1 and the locations depicted on Figure 2 should be considered accurate only to the degree permitted by our data sources and implied by the measuring methods. j It should be realized that the explorations performed for this evaluation reveal subsurface conditions only at discrete locations across the project site and that actual conditions in other areas could vary. Furthermore, the nature and extent of any such variations would not become evident until additional explorations are performed or until construction activities have begun. If significant variations are observed at that time, we may need to modify our conclusions and recommendations contained in this report to reflect the actual site conditions. 4.0 SITE CONDITIONS The following sections of text present our observations, measurements, findings, and interpretations regarding utility, surface, soil, groundwater, seismic and liquefaction conditions at the project site i 4.1 UTILITY CONDITIONS Based on the site plans supplied to us and surface markings provided by the utility locating specialists, underground utilities that are known to cross the proposed southern culvert alignment consist of electrical, gas and water. Those underground utilities that are known to cross the northern culvert alignment are electrical, gas, water, telephone and a sanitary sewer line at the south end of the culvert Also, there is overhead street lighting along the west side of 641h Avenue S that could be impacted during the culvert replacement project. I AMEC Environment& Infrastructure, Inc. 4 Project No 1-91 7-1 7292-0 P 117292-0_641h Ave S_Channel Improvemen1slGeoReporls164th Ave S Eng Rpl Draft 111412 docx ame& 4.2 SURFACE CONDITIONS Our observations of the surface conditions for the two channel crossings were made during our site visits on August 26 and November 10, 2011. Both existing channel crossings consist of three 60-inch- diameter concrete culverts with Invert elevations of 21 feet to 22 feet The topographic relief around the channel is relatively flat-lying with elevations ranging from 30 to 34 feet. There is a 25-foot wide paved private entry off of 641h Avenue S drive just south of the 60-foot wide railroad right-of-way. At the S 226" Street intersection with 641h Avenue S, the entrance and exit from S 2261h Street consists of single paved lanes separated by a median. Approximately 60 feet to the west of the channel, there is a paved public trail that parallels the channel in a north-south direction. i The existing drainage channel is approximately 65 to 70 feet in width and is bordered by a row of secondary growth deciduous trees (with a scattering of conifer trees)from the south end of the project side to the south side of S 2261h Street There are a couple of young deciduous trees on the grassy median in S 226g'Street Vegetation along the slopes of the channel consists of blackberry bushes, ivy, and grasses The channel has cattails and a variety of grasses. Surface water in the channel runs in a south to north direction. 4.3 SOIL CONDITIONS According to published geologic maps (Mullineaux, 1970)the project site is located along the eastern flank of the Duwamish Valley in the Puget Sound lowland The Duwamish Valley lies within a broad glacial drift plain developed from multiple episodes of glaciation occurring during Pliestocene time, The glacial drift plain is underlain by Tertiary age bedrock at depth. The Duwamish Valley is believed to have been incised into the glacial drift plain from scouring of the Puget lobe and as a relict subglacial melt-water channel during the retreat of glacial ice during the Vashon Stade of Fraser glaciation The Duwamish Valley was occupied by proglacial lakes, and later filled by progradation of deltas from both the White and Green rivers supplied with sediment from Mt Rainier lahars Our explorations revealed somewhat uniform near surface soil conditions and confirmed the mapped stratlgraphy throughout the project site. Based on the information attained, the depositional environments for the sediments in the project area are comprised of floodplain (overbank and backwater pond) and channel deposits interfingered with deltaic deposits consisting of silty sands, sandy silts, clayey silts and peat, and andesitic sands, respectively The observed soil deposits can be summarized as several layers with similar physical properties, as described below • Fill. We observed soil which we interpreted to be fill (Hf) placed along the channel alignment to depths of 5 feet below the ground surface The fill soils are comprised of medium stiff to hard sandy silts to medium dense silty sand with some gravel, cobbles and quarry spalls Larger AMEC Environment& Infrastructure, Inc.

Since our explorations were advanced outside the zone of backfill for the existing culverts, we expect that fill thickness may approach 10 to 12 feet in center of channel • Upper Floodplain Deposits- Beneath the fill soils there are overbank and backwater pond deposits (He) consisting of very soft to medium stiff silts to sandy silts with trace to some organics present in borings B-1 and B-4 for a thickness of 18 to 25 feet Within these deposits in borings B-2 and B-3 there are loose to medium dense silty fine sand layers that range in thickness from 2 to 9 feet. • Alluvial Deposits Beneath the upper floodplain deposits (He) are alluvial deposits (Ha) consisting of medium dense blackish gray silty fine sand with trace organics. These deposits range in thickness from 5%2 feet at boring B-4 to 18 feet at boring B-2 • Lower Floodplain Deposits- The alluvial deposits (Ha) are underlain by very stiff sandy silt to medium dense silty sand overbank (He) deposits in boring B-4 to a depth of 43 feet below the ground surface. At 43 feet below the ground surface, borings B-2 and B-4 both encountered backwater pond deposits (He) of very soft silt with some clay and organics to the full depth of our explorations of 51%feet.

This perched groundwater develops when the vertical infiltration of water through a shallow, more permeable soil is slowed by a deeper, less permeable soil. Because our explorations were performed during an extended period of generally dry weather, the groundwater conditions present at that time may closely represent the yearly low levels; somewhat higher levels probably occur during the winter and early spring months It appears the fine-grained floodplain deposits beneath the channel act as an aquitard, partly separating the perched aquifer from the groundwater observed within the sandy alluvium at elevation 4 to 8 feet Groundwater seepage would therefore be anticipated during wetter portions of the year, where sandy interbeds occur below the level of the channel bottom Throughout the year, groundwater levels would likely fluctuate in response to changing precipitation patterns, off- site construction activities, and site utilization. 4.5 SEISMIC CONDITIONS Based on our analysis of subsurface exploration logs and our review of published geologic maps,we interpret the on-site soil conditions to correspond to a seismic site class D, as defined by Table 3 4 2 1-1 of the 2009 American Association of State Highway and Transportation Officials (AASHTO) AMEC Environment& Infrastructure, Inc ProiectNo 1-917-17292-0 7 P 117282-o_641h Ave S_Channel ImprovemenWGeoRep0ds164th Ave S Eng Rpt Draft 111412 docx I � amec'0 manual entitled Guide Spectfications for LRFD Seismic Design First Edition Based on review of AASHTO seismic hazard maps, AMEC recommends using the following parameters for Seismic Site Class D: Ss = 1.318 Fa = 1.0 SDs = 1 318 S1 = 0 449 Fv = 1 55 SDI = 0 696 • Fpga= 1.0 (site coefficient for peak ground acceleration) The AASHTO maps are labeled with a probability of exceedance of 7 percent in 75 years corresponding to a return interval of 1,000 years Current (2007) Probabilistic Uniform Response Spectra Data prepared by the USGS for 7 percent in 75 years indicate a peak bedrock site I acceleration coefficient of about 0.43g. 4.5.1 Liquefaction Evaluation �I Liquefaction is a sudden increase in porewater pressure and a sudden loss of soil shear strength caused by shear strains, as could result from an earthquake Research has shown that saturated, loose sands with a fines (silt or clay) content less than about 25 percent are most susceptible to liquefaction Although other sod types are generally considered to have a low susceptibility, liquefaction may still occur during a strong earthquake. Typically, due to confinement, liquefaction does not extend deeper than about 50 feet below ground surface Our on-site subsurface explorations did reveal saturated (or potentially saturated), loose, clean to silty sand layers or lenses within the upper 50 feet, as discussed above. To evaluate the possibility that the on-site native sands could liquefy during a seismic event, we performed a liquefaction analysis based on these site conditions, For purposes of evaluating liquefaction potential,we used the computer program SHAKE2000 to evaluate liquefaction based on the equation for factor of safety against liquefaction This program evaluates the cyclic resistance ratio (CRR) required to initiate liquefaction based on Standard Penetration Test(SPT) results, as recommended by Seed, et al. (1983, 1985), and recently reviewed in the Proceedings of the NCEER Workshop on Evaluation of Liquefaction Resistance of Soils (Youd, et al 1997, 2001) We evaluated the potential for liquefaction assuming a magnitude 7 5 earthquake with a peak ground r acceleration of 0 43 g We used this method to determine the relative factor of safety against liquefaction for the loose, silty sand layers underlying the site vicinity Our analyses revealed that the loose to medium dense sand and very soft to stiff sandy silt layers have a high potential for liquefaction We analyzed the liquefaction-induced settlement potential using the method developed by Tokimatsu and Seed (1987) Based on our analysis, we estimate that liquefaction-induced settlements in the upper 50 feet of site soils to be on the order of 6 to 12 inches AMEC Environment&Infrastructure, Inc 8 Protect No 1-917-17292-0 P 117292-0_641h Ave S_Channel Improvemenis\GeoRepods1641h Ave S Eng Rpt Draft 111412 docx Amok ame 5.0 CONCLUSIONS AND RECOMMENDATIONS Improvement plans call for replacement of the two existing culvert crossings with concrete box culverts We offer the following general geotechnical conclusions and recommendations concerning this project. Feasibility Based on our field explorations, research, and analyses, the proposed culvert replacements appear feasible from a geotechnical standpoint, contingent on the recommendations presented herein Culvert Foundation Considerations- Subgrade Improvement will need to be accomplished to provide adequate bearing capacity for the new culverts. The method selected will depend on tolerable settlements from underlying compressible native soils If minimal settlement is required at the railroad crossing and E80 Cooper loading needs to be assumed the subgrade should be Improved using compacted aggregate piers or deep foundations. At the S. 226th Street crossing, overexcavation and replacement with a 4-foot thick bearing pad of quarry spalls appears feasible. 1 Temporary Sloping and Shoring Considerations: We expect that S 226th Street may be partially closed and that the railway spur will be out of service during construction of the new culverts While temporary sloping may be feasible toward the west, it is likely that temporary cut slopes cannot be accommodated to the east due to proximity to 641h Avenue. Temporary shoring may therefore be required to construct the replacement culverts Based on soil conditions, temporary shoring using sheet piles appears feasible. Liquefaction Considerations- Liquefaction is a sudden increase in porewater pressure and sudden loss of sod shear strength caused by shear strains, as could result from an earthquake Research has shown that saturated, loose sands with a silt content less than about 25 percent are most susceptible to liquefaction, whereas other soil types are generally considered to have a lower susceptibility Our analysis Indicated that the soils underlying the project site have a high susceptibllty to liquefaction during a strong earthquake (AASHTO 1,000 year return interval event) Liquefaction Mitigation: Our analyses indicate that settlement due to liquefaction of soils between a depth of 20 to 25 feet and 35 to 50 feet could be on the order of 6 to 12 Inches. Based on our iknowledge of subsurface conditions In the vicinity of the site, we anticipate widespread liquefaction will likely occur during a seismic event Mitigation of liquefaction settlement could be accomplished beneath the new culverts using compacted aggregate piers or deep foundations, however, this would AMEC Environment& Infrastructure, Inc Project No.1-917-17292-0 9 P 117292 0_841h Ave S Channel ImprovemenhkGeoRepodM640 Ave S Eng Rpt Draft 111412 doc% i amen result in a significant amount of differential settlement between improved and adjacent unimproved areas On-site Sal Reuse. Our visual sod classifications and laboratory testing indicate that the on-site soils �I are over-optimum and highly moisture-sensitive and susceptible to disturbance when wet To maximize the potential for reusing on-site soils as structural fill, earthwork should be scheduled for periods of dry weather, such as that usuaily occurring during the summer and early fall months Subarade Protection. Due to the moisture-sensitive nature of the on-site soils, the contractor should Install appropriate temporary drainage systems to keep water out of the construction areas, and should minimize traffic over any subgrades prepared within these soils. The following text sections of this report present our specific geotechnicai conclusions and recommendations concerning site preparation, excavations, culvert footings, temporary and permanent slopes, and structural fill American Society for Testing and Materials (ASTM) specification codes cited herein refer to the current ASTM manual Washington State Department of Transportation (WSDOT) specification codes and plan designations cited herein refer to WSDOT publications M41- 10, 2010 Standard Specifications for Road, Bridge, and Municipal Construction, and M21-01, Standard Plans for Road, Bridge, and Municipal Construction, respectively 5.1 SITE PREPARATION Depending on the contractor's work plan and sequencing, preparation of the project site may involve erosion control, pavement removal and demolition, temporary diversion, drainage, and dewatering, temporary sloping /shoring, and excavations, followed by backfilling and site restoration. The paragraphs below discuss our geotechnical comments and recommendations concerning site preparation Erosion Control Measures It is recommended that a staked silt fence be installed around the area to be disturbed The base of the silt fence should be buried so that sediment cannot pass beneath it, and the silt fence should be inspected and maintained during the time that the site soils are exposed, on a periodic basis, and after any major rainstorm event Because stripped surfaces and soil stockpiles are typically a source of runoff sediments, they should be given particular attention If earthwork occurs during wet weather, we recommend that all stripped surfaces be covered with straw to reduce runoff erosion Similarly, soil stockpiles and cut slopes should be covered with plastic sheeting for erosion protection It may be prudent to maintain a berm and swale around the downslope side of stripped areas and stockpiles In order to capture runoff water and thereby reduce the downslope sediment transport In addition, the stripped areas should be revegetated as soon as possible, also reducing the potential for erosion.

Removal of the existing culverts may need to occur in sections depending on the Contractor's work plan The roadway embankment on both sides of the project site ranges between approximately 10 to 12 feet high as measured from the road grade to the culvert's invert elevation. Temporary Drainage: We recommend intercepting and diverting any potential sources of surface or near-surface water within the construction zones before stripping begins. Because the selection of an appropriate drainage system will depend on the water quantity, season, weather conditions, construction sequence, and contractor's methods,final decisions regarding drainage systems are best made in the field at the time of construction. Nonetheless, we anticipate that curbs, berms, or ditches t placed around the work areas to adequately intercept surface water runoff Temporary Dewatering, Our explorations encountered groundwater in the alluvial deposits at depths ranging from 23 to 27 feet below ground surface (elevations from 4 to 8 feet) Also, we encountered perched groundwater ranging from 10 to 15 feet below the ground surface (elevations of 16 to 23 feet) e approximate level of the surface water in the e channel We expect that drainage corresponding to the pprox 9 groundwater levels will rise several feet during the winter and spring Consequently, site excavations might extend below the groundwater level, depending on the actual excavation depth and time of year. If groundwater is encountered, we anticipate that an Internal system of ditches, sumpholes, and pumps will be adequate to temporarily dewater the excavation If compacted aggregate piers are used for culvert support, the contractor should expect higher groundwater flows into the excavation. Temporary Cut Slopes: All temporary cut slopes associated with site excavations should be adequately inclined to prevent sloughing and collapse For the various sod layers that will likely be exposed in on-site cuts, we tentatively recommend the following maximum cut slope inclinations However, appropriate inclinations will ultimately depend on the actual soil conditions exposed during earthwork Maximum Soil Type Inclination Existing Embankment Fill 1'/zH,1V Floodplain Deposits 2H 1V Note Temporary slopes are for soils without seepage Where seepage occurs, dewatering would be required, otherwise temporary slope inclinations would need to be flatter AMEC Environment& Infrastructure, Inc j t ProectNo 1-917-17292-0 it P W292-0_641h Ave S_Channel ImprovementslGeoRepods1641h Ave S Eng Rpt Draft 111412 dou t . amec,O Temporary Shoring- If temporary cut slopes cannot be accommodated due to site constraints, and �I worker access is necessary within the excavations, temporary shoring would need to be installed prior to excavation Temporary shoring may also be required to support the roadway embankment if a i single lane of traffic Is to be maintained through the work area 5.2 TEMPORARY SHORING WALLS Temporary shoring walls should be constructed along any excavation sidewalls that cannot be adequately sloped or set back. We offer the following design and construction recommendations concerning temporary shoring Applicability In our opinion, sheet piles could be used for shoring the proposed culvert excavation sidewalls at the site The design of temporary shoring walls should be the responsibility of the contractor. The contractor will need to submit a shoring design and a work plan describing proposed means and methods for construction as well as a program for deflection monitoring, if required for protection of surrounding roadways, utilities or other structures.. Pile Embedment All sheet piles should have sufficient embedment below the final excavation level to provide adequate "kick-out" resistance to horizontal loads. We recommend a minimum embedment of 10 feet below the excavation base, or 5 feet below any excavations located within about 15 horizontal feet of the pile, whichever is greater However, deeper embedments might be needed to develop adequate vertical capacity or passive resistance at specific locations. Installation Conditions- Based on our explorations, we expect that sheet pile walls will encounter site soils comprised of very soft to hard sandy silt and loose to medium dense silty sands Installation of sheet piles using a vibratory hammer appears feasible within the site sods. Although the explorations did not encounter buried logs, It should be noted that these obstructions could exist at random locations within these flood deposits. Applied Loads: Temporary shoring walls should be designed to resist the various applied loads, which can be classified as static pressures, surcharge pressures, and hydrostatic pressures Our recommended design pressures are discussed in the following paragraphs. • Static Pressures- Static lateral earth pressures are assumed to act over the entire height of the wall. For walls that are cantilevered, we generally recommend using an active earth pressure modeled as an equivalent fluid unit weight equal to 40 pcf In the special case of walls that are located adjacent to existing structures or sensitive utilities, we recommend using an appropriate at-rest earth pressure of 60 pcf, this will minimize lateral deflections of the wall face and vertical subsidence of the backslope surface For walls that are cantilevered, we AMEC Environment& Infrastructure, Inc. 12 Protect No 1-917-17292.0 P U7292-0_64th Ave S_Channel Inlprovemen1slGeeReporis164th Ave S Enq Rpt Draft 111412 docx amec'0 generally recommend using an active earth or at-rest pressure modeled as equivalent fluid unit weights (with a triangular pressure distribution) of 40 pcf and 60 pcf, respectively • Surcharae Pressures. Lateral earth pressures acting on the shoring wall should be increased to account for surcharge loads resulting from any vehicle traffic, railroad equipment(Cooper E80 Loading) if applicable , construction equipment, material stockpiles, or structures located within a horizontal distance equal to the wall height. • Hydrostatic Pressures: If adequate drainage Is provided behind the shoring wall, we expect that hydrostatic pressures will not develop However, if groundwater were allowed to collect behind the wall, a hydrostatic pressure of 62 pcf would act against the portion of wall above the foreslope level and below the saturation level. Resisting Forces Lateral resistance can be computed by using an appropriate allowable passive earth pressure acting over the embedded height of the temporary shoring wall, neglecting the upper 2 feet. For a level foreslope, the allowable passive pressure can be modeled as a trapezoidal distribution Assuming a level foreslope at the wall location, we recommend the design values of 200 pounds per cubic foot for static conditions and 270 pounds per cubic foot for seismic conditions. These values incorporate static and seismic safety factors of at least 1.5 and 1.1, respectively, An allowable coefficient of base friction of 0.30 may be assumed between the soil and concrete for static conditions Base friction is typically neglected under seismic loading conditions Construction Monitoring. We recommend that an AMEC representative be retained to continuously Imonitor the construction of the temporary shoring walls, to verify that suitable depths are reached and soil conditions encountered are consistent with those assumed. This monitoring program would include observation and documentation of installation procedures, construction materials, driving conditions, soil conditions, and pile plumbness. 5.3 BOX CULVERTS The soft silts underlying the proposed culvert locations are moderately compressible and settlement will be a function of culvert crossing loading, bearing pad thickness and bearing pad material type. The bearing pad will serve to dissipate foundation stresses uniformly across the culvert, thereby reducing total and differential post-construction static settlement. Bearing Pads, We evaluated settlement of bearing pads comprised of lightweight aggregate fill and quarry spalls ranging In thickness from 2 to 4 feet. Neglecting the loading from vehicle or railroad ; traffic, the new culverts will impose no new net loading to the site soils Overexcavation and replacement with lightweight fill will also not impose any new soil loading as It weighs less than the native sods that would be removed However, using quarry spalls would impose a net increase in load j applied to the native soils which would cause settlement as it is much heavier.

An array of aggregate piers would improve the bearing capacity of sods beneath structures This approach would limit static and seismic settlements to less than 1 inch. A "Geopier" or"Vibropier'are proprietary names for the most common type of aggregate pier, but others might be available Regardless of type, all aggregate piers are installed by boring down to a suitable soil horizon and then backfilling the borehole with compacted granular soil Typical borehole diameters range from about 30 to 42 inches For all locations, we recommend the aggregate pier designer ensure that the piers have sufficient depths and widths to provide an allowable bearing capacity of 3,000 psf. Surcharge loading. Given the infrequent trams that will be travelling across the railroad spur each year; we assumed this live load can be neglected in our static settlement calculations However, we consider the live load for the culvert crossing beneath S 226't' Street that is subjected to frequent truck traffic applicable in evaluating static settlement Estimated Settlement* A summary of estimated settlement for various subgrade improvement options is presented in Table 4 below Table 4 Estimated Settlements for Sub grade Improvement Options Estimated Settlement Location Subgrade Improvement Options (inches) Railroad Crossing 2-foot bearing pad using lightweight Less than 1 inch aggregate fill assuming no railroad surcharge 4-foot bearing pad using lightweight 7 _ aggregate fill assuming ESO Cooper railroad surcharge (3,000 psf) Aggregate Piers assuming ESO Less than 1 inch Cooper railroad surcharge (3,000 sf S 226th Street Crossing 4-foot bearing pad using quarry Less than 1 inch spalls assuming H-20 surcharge (1,000 psf) Recommended Option At the railroad crossing, the preferred option would be to support the culvert using compacted aggregate piers unless the railroad surcharge can be neglecter! Aggregate piers would also have the benefit of mitigating the native sandy soils for liquefaction settlement. At the 226g' Street crossing,we recommend removal of the soft silt layer and replacement with a 4 foot bearing pad using comprised of spalls AMEC Environment& Infrastructure, Inc. 14 Project No 1-917-17292-0 P 117292-0_64th Ave S_Channel improvemenls\G¢oReportsl6,th Ave S Eng Rpt Draft 111412 dacx dme 5.4 BACKFILLED WALLS Lateral earth pressures will act on the walls of the proposed box culverts. Recommended design parameters for backfilled walls are presented below. Curtain Drains: To preclude hydrostatic pressure development behind the retaining walls, we recommend that a curtain drain be placed behind the entire wall This curtain drain should consist of pea gravel, washed rock, or some other clean, uniform, well-rounded soils, extending outward a minimum of 1 foot from the wall and extending from the footing drain upward to within about 12 inches of the ground surface We also recommend that a minimum 4-inch-diameter perforated drain pipe be installed behind the heel of the wall. Applied Loads Overturning and sliding loads applied to retaining walls can be classified as static pressures, surcharge pressures, seismic pressures, and hydrostatic pressures. We offer the following specific values for design purposes Static Pressures: At-rest pressures should be utilized for non-yielding (restrained) walls. Assuming a level backslope, we recommend using an at-rest pressure of 60 pounds per cubic foot (pcfl Seismic Pressures- Static lateral earth pressures acting on a backfilled retaining wall should be increased to account for seismic loadings However, this would not be applicable to the buried culvert structures with equal pressures on either side These pressures should, however be considered for the case of unbalanced loading such as a wing wall or similar retaining wall If the unbalanced retaining wall condition is required, these pressures would act over the entire back of the wall and vary with the backslope inclination, the seismic acceleration, and the wall height Based on a design acceleration coefficient of at least 0.43g for an earthquake having a 7 percent probability of exceedance in 75 years (corresponding to a return Interval of 1000 years) and a wall height of"H" feet, we would recommend that this seismic loading be modeled as the following uniform horizontal pressures for level ground. Backslope Angle Active Pressure At-Rest Pressure Level 12H psf 36H psf Hydrostatic Pressures If groundwater is allowed to saturate the backfill soils, a hydrostatic pressure will act against a retaining wall below the saturation level and above the foreslope level In contrast, if an adequate drainage and discharge system is Included behind the retaining wall, we do not expect that hydrostatic pressures will develop. f AMEC Environment& Infrastructure, Inc.

These values incorporate static and seismic safety factors of at least 1 5 and 1.1, respectively An allowable coefficient of base friction of 0.30 may be assumed between the soil and concrete for static conditions. Base friction is *, typically neglected under seismic loading conditions. 5.5 PERMANENT SLOPES Restoration of embankment and channel slopes will be required at the completion of culvert replacement Provided below are recommendations for embankment construction Permanent Slope Restoration. All permanent fill slopes should be adequately inclined to minimize long-term raveling, sloughing, and erosion. We generally recommend that no slopes be steeper than 2H 1V(Horizontal Vertical) above any portion of slope exposed to standing or flowing water For all portions below water, a 3H 1V or flatter slope is recommended. Slopes should be maintained until grass vegetation is fully restored Subgrade Conditions: All existing organic matter, sod, topsoil, and other deleterious materials should be stripped from the area to receive fill. We recommend the exposed subgrade be observed by a qualified geotechnical engineer or engineering geologist prior to fill placement. Embankment Soils. In our opinion, excavated on-site fill soils are not suitable for reuse as embankment fill. We recommend using imported granular soils such as "Gravel Borrow' per 2010 WSDOT Standard Specification 9-03.14(1) The Structural Fill section of this report discusses various moisture-content considerations and restrictions for fill soils, Benching, We recommend that a series of horizontal benches be cut into the existing roadway embankment before or during construction of the new embankments The final slopes should be constructed as terraced fills upon a stable subgrade, in accordance with WSDOT 2-03 3(14) Embankment construction, Hillside Terraces, In our opinion, these benches should have a maximum height of 4 feet and a minimum width of 4 feet. Fill Placement and Compaction We generally recommend that all embankment fill be placed and compacted in accordance with Method B of 2010 WSDOT Standard Specification 2-03 3(14)C AMEC Environment& Infrastructure_, Inc 16 Project No 1-917-17292-0 P%17292-0_641h Ave S_channel Improvemenis%GeoReportM64%Ave S Eng Rpt Draft 111412 doex i I eme I Method B stipulates that the upper 2 feet of the embankment be compacted to 95 percent of the maximum dry density in accordance with WSDOT Test Method 606 and that all soils below a 2-foot depth be compacted to 90 percent of this same maximum density The Structural Fill section of this report provides additional criteria regarding fill sods and placement methods, Slope Protection We recommend that a permanent berm, swale, or curb be constructed along the top edge of all permanent slopes to intercept surface flow In addition, a hardy vegetative groundcover should be established as soon as feasible, to further protect the slopes from runoff water erosion Alternatively, permanent slopes could be armored with quarry spalls or a geosynthetic erosion mat. 5.6 STRUCTURAL FILL The term "structural fill" refers to any materials used for roadway embankments, as well as materials placed under foundations, retaining walls, sidewalks, pavements, and other features Our comments, conclusions, and recommendations concerning structural fill are presented in the following paragraphs. Materials- Typical structural fill materials include clean sand, granulithic gravel, pea gravel, washed rock, crushed rock, quarry spalls, controlled-density fill (CDF), lean-mix concrete (LMC), well-graded mixtures of sand and gravel (commonly called "gravel borrow" or"pit-run"), and miscellaneous mixtures of silt, sand, and gravel Recycled asphalt, concrete, and glass, which are derived from pulverizing the parent materials, are also potentially useful as structural fill in certain applications, Soils used for structural fill should not contain any organic matter or debris, or any individual particles greater than approximately 6-Inches in diameter. Fill Placement: Generally, pea gravel, washed rock, quarry spalls, CDF, and LMG do not require special placement and compaction procedures In contrast, clean sand, granulithic gravel, crushed rock, soil mixtures, and recycled materials should be placed in horizontal lifts not exceeding 8-inches in loose thickness, and each lift should be thoroughly compacted with a mechanical vibratory compactor jCompaction Criteria Using the Modified Proctor test(ASTM D-1557)as the standard, we recommend structural fill be used for various on-site applications and compacted to the following minimum densities, Fill Application Minimum Compaction Culvert subgrade 90 percent Railway embankment 95 percent Roadway embankment(upper 2 feet) 95 percent AMEC Environment& Infrastructure, Inc. Protect No 1.917-17292-0 17 P 117292-0_64th Ave S_Channel ImprovementslGeoReports1641h Ave S Eng Rpi Draft 111412.doex 1 i amec,O Roadway embankment(below 2 feet) 90 percent Subgrade Verification and Compaction Testing; Regardless of material or location, all structural fill should be placed over firm, unyielding subgrades prepared in accordance with the Site Preparation section of this report The condition of all subgrades should be verified by an AMEC representative before filling or construction begins In addition, fill soil compaction should be verified by means of in- place density tests performed during fill placement so the adequacy of the soil compaction efforts may be evaluated as earthwork progresses Soil Moisture Considerations The suitability of soils used for structural fill depends primarily on their grain-size distribution and moisture content when they are placed As the "fines"content (the soil fraction passing the U.S No 200 Sieve) increases, sods become more sensitive to small changes in moisture content. Soils containing more than about 5 percent fines (by weight) cannot be consistently compacted to a firm, unyielding condition when the moisture content is more than 2 percentage points above or below optimum. For fill placement during wet-weather site work, we recommend using "clean"fill, which refers to soils that have a fines content of 5 percent or less (by weight), based on the soil fraction passing the U S. No 4 Sieve CDF Strength Considerations CDF is normally specified in terms of its compressive strength, which typically ranges from 50 to 200 psi CDF having a strength of 50 psi (7,200 psf) provides adequate support for most structural applications and can be readily excavated with hand shovels A strength of 100 psi (14,400 psf) provides additional support for special applications but greatly increases the difficulty of hand-excavation. In general, CDF having a strength greater than about 100 psi requires power equipment to excavate and should not be used where future hand-excavation might be needed Subgrade Compaction- Exposed subgrades for culverts, pavements, and other structures should be compacted to a firm, unyielding state Any localized zones of loose granular soils observed within a subgrade should be compacted to a density cornmensurate with the surrounding soils Onsite Soils We offer the following evaluation of the on-site soils in relation to potential use as structural fill • Sarflcial Organic Soils The sod, duff, topsoil, and organic-rich sods mantling most of the site are not suitable for use as structural fill under any circumstances, due to their high organic content Consequently, these materials can be used only for non-structural purposes, such as in landscaping areas.

The embankment fill soils consisted of silty gravelly sand and would be suitable for reuse as structural fill, contingent upon moisture content of the material and its ability to be compacted to meet project specifications There may be zones of organics, rubble, or similar deleterious material which would need to be segregated prior to reuse of these materials as structural fill. • Alluvial Deposit Sods- The alluvial sand deposit sods do not appear suitable for reuse as structural fill at their present moisture content. It is anticipated these sods may only become suitable for reuse during an extended period of dry weather if they can be aerated to reduce itheir moisture content. s • Floodofaln Deposit Soils-The silty sands/sandy silts do not appear suitable for reuse as structural fill at their present moisture content It is anticipated these sods may only become suitable for reuse during an extended period of dry weather if they can be aerated to reduce their moisture content These soils could be difficult or Impossible to reuse during wet weather, due to their moderate silt contents. 6.0 RECOMMENDED ADDITIONAL SERVICES 1 Because the future performance and integrity of the structural elements will depend largely on proper site preparation, drainage, fill placement, and construction procedures, monitoring and testing by experienced geotechnical personnel should be considered an Integral part of the construction process Consequently, we recommend that AMEC be retained to review or provide the following post-report services* • Review all construction plans and specifications to verify that our design criteria presented in this report have been properly Integrated Into the design; Prepare a letter summarizing all review comments (if required by City of Kent); • Attend a pre-construction conference with the design team and contractor to discuss Important geotechnically related construction issues, • Monitor the installation of all shoring walls to verify conformance with the construction plans and to document the contractor's procedures, • Review all shoring wall deflection data collected by the project surveyor; Observe all exposed subgrades after completion of stripping and overexcavation to confirm that suitable soil conditions have been reached and to determine appropriate subgrade compaction methods, AMEC Environment&Infrastructure, Inc Project No 1-917-17292-0 19 P 117292-o_64th Ave S_Channel Improvements%GeoReporls1641h Ave S Eng Rpl Draft 11102 docx amec* • Monitor the installation of aggregate piers to verify embedment depth and construction , methods, • Monitor the placement of all structural fill and test the compaction of structural fill soils to verify their conformance with the construction specifications, , • Check all completed subgrades for footings before concrete is poured, in order to verify their bearing capacity; �I • Prepare a post-construction letter summarizing all field observations, Inspections, and test results (If required by City of Kent). �I AMEC Environment& Infrastructure, Inc. 20 Project No 1-917-17292-0 P M292-0 64th Ave S_Channel ImprovementskOeoReporW54th Ave S Eng Rpt Draft 111412 docx amecle 7.0 CLOSURE The conclusions and recommendations presented in this report are based, in part, on the explorations AMEC performed and used for this study; therefore, if variations in the subgrade conditions are observed at a later time, we may need to modify this report to reflect those changes In addition, because the future performance and Integrity of the project elements depend largely on proper initial site preparation, drainage, and construction procedures, monitoring and testing by experienced geotechnical personnel should be considered an integral part of the construction process AMEC is available to provide earthwork monitoring, soils testing, and geotechnical engineering services throughout construction.

Descriptive logs of our explorations are enclosed in this appendix AUGER BORING PROCEDURES Our exploratory borings were advanced with a hollow-stem auger, using a truck-mounted drill rig operated by an independent drilling firm working under subcontract to AMEC An engineering geologist from AMEC continuously observed the borings, logged the subsurface conditions, and collected representative sod samples All samples were stored in watertight containers and later transported to our office for further visual examination and assignment of lab testing After each boring was completed, the borehole was backfilled with a mixture of bentonite chips and soil cuttings, and the surface was patched with asphalt or concrete (where appropriate). Throughout the drilling operation, soil samples were obtained at 2 5-or 5-foot depth intervals by means of the Standard Penetration Test (SPT) per American Society for Testing and Materials (ASTM) D-1586. This testing and sampling procedure consists of driving a standard 2-inch diameter I steel split-spoon sampler 18 inches into the sod with a 140-pound hammer free-falling 30 inches The number of blows required to drive the sampler through each 6-inch interval is counted, and the total number of blows struck during the final 12 inches is recorded as the Standard Penetration Resistance, or"SPT blow count." If a total of 50 blows are struck within any 6-inch interval, the driving is stopped and the blow count is recorded as 50 blows for the actual penetration distance The resulting Standard Penetration Resistance values indicate the relative density of granular soils and the relative consistency of cohesive sods. >� The enclosed Boring Logs describe the vertical sequence of soils and materials encountered in each boring, based primarily on our field classifications and supported by our subsequent laboratory examination and testing Where a sod contact was observed to be gradational, our logs indicate the average contact depth. Where a sod type changed between sample intervals, we inferred the contact depth Our logs also graphically indicate the blow count, sample type, sample number, and approximate depth of each sod sample obtained from the borings, as well as any laboratory tests iperformed on these sod samples, If any groundwater was encountered in a borehole, the approximate groundwater depth is depicted on the boring log Groundwater depth estimates are typically based on the moisture content of soil samples, the wetted height on the drilling rods, and the water level measured in the borehole after the auger has been extracted 1 I t PROJECT, 64th Avenue S-Channel Improvements JOB No, 1-917-17292-0 BORING No B-1 Soil Description N 0 W z a .

See Standard Plan 3-2. A hydrant meter and an approved backflow prevention device shall be used whenever drawing water from the City's water system. Hydrant meters and backflow prevention devices may be obtained from the Public Works Operations Division, Water Section located at 5821 South 240th Street. The Contractor will be required to complete the billing forms for a Water Permit and making the required damage deposit. There will be a charge for all water i used in accordance with KCC 7.02.180 - Temporary Water Meters. ■ Prior to the new watermain being installed, the Contractor has the option of cutting in the connection tee on the existing watermain, or providing potable water from an existing hydrant or blowoff to provide a temporary water supply. If the contractor chooses the option of installing a new connection - tee, the contractor shall install new resilient wedge valves on all sides of the tee, or otherwise as required by the Engineer. A mechanical joint plug with a 2" minimum tap and proper blocking shall be installed on the new incoming mainline valve at the new tee with piping accessible to accommodate filling ' the new water main. 3.22 CUBING iFoam cubes (pigs) shall be inserted into and pushed through the new water main to remove any residue, dirt, debris, obstruction or possible foreign material in the new water main. 3.22.A Cube Usage ' 1. The Water Section will supply the foam cubes to the Contractor based on the water system design as shown on the approved Engineering Plan. 2. The Contractor shall pickup the cubes at Public Works Operations and shall install two (2) foam cubes at the initial connection and two (2) foam cubes at each lateral connection 6" in diameter and larger (downstream of each connecting valve), as the new main is installed. This would include all 6" and larger diameter lateral runs to hydrants that are longer than one full pipe length, or have more than a single joint in them. 3. A mechanical joint cap with a 2" minimum tap shall be installed ' with proper blocking at the initial connection point on the new main with piping accessible to accommodate both flushing and , chlorine injection. 4. The Water Section shall retrieve the foam cubes when the contractor performs the cubing process. All cubing and flushing shall be under the supervision of the Water Section or the Inspector. 5. To accommodate the launch and the retrieval of the cubes, the minimum blow-off size shall be 6" for watermain diameters up to 12 6. It shall be the contractor's responsibility to properly dispose of all flush water per Section 3.23 below as well as locating and retrieving any "lost" or missing cubes or partial cubes from the watermain. 7. In the event that the initial cubing does not adequately clean the new water mains, the contractor shall be required to provide additional point(s) for launching and retrieval of additional cubes, and re-cube those sections of main that have debris in them until clean, as determined by the Water Section. 3.23 CHLORINE INJECTION After the Contractor has cleaned the watermain by Cubing and flushing, the Contractor shall inject a liquid chlorine solution evenly throughout the new , main and all connections and Appurtenances for complete and optimal disinfection. The chlorine dosage shall be a minimum of 50 mg/I and a maximum of 100 mg/l. AWWA C651-99 Standards include detailed ' procedures for the adequate disinfection, flushing and microbiological testing of all watermains. If the Contractor wishes the Water Section to do the injection, the Inspector shall give the Water Section five (5) working days notification to perform the chlorine injection. The Contractor must sign a waiver holding the City harmless for any failure of purity samples due to the work performed by the Water Section, as well as agreeing to reimburse the City for all costs associated with the disinfection process. Work may be scheduled after hours, outside of the 5-day notification period, or refused by the City due to manpower or workload constraints. ' The chlorine shall remain in the main for the time specified according to the procedure used from AWWA Standards C651-99. After the 24-hour disinfection period, the remaining residual throughout the watermain and Appurtenances shall not be lower than 25 mg/L, if so it would require reapplication of chlorine. The Contractor shall be responsible for disposing of all chlorinated water. Chlorinated water shall be disposed of in an approved sanitary sewer. If a sanitary sewer is not available, or the capacity of the sanitary sewer will be at risk, the Contractor shall be responsible for disposing of the water per all applicable regulations. Amount of chlorine needed to produce 50mg/L in 18' of pipe (one pipe length) for 5.25% household bleach (with no additives), 12.5% sodium hypochlorite solutions and 65% available dry calcium hypochlorite is shown in the following table.

Costs shall be the actual costs including hourly overtime rate for labor, overhead, equipment and materials and any other associated charges. The costs shall be based on the latest cost schedule prepared and approved annually by the Engineer. ' 3.24 BACTERIOLOGICAL PURITY SAMPLES Two (2) consecutive sets of acceptable purity samples, taken at least 24 hours apart, shall be collected from representative points of the new watermain, all appurtenances and all other connections to the new watermain(s). Water Section personnel will take the first bacteriological purity sample(s) after the chlorine is removed, flushing is completed and the chlorine level is no greater than, or less than, the level present in the adjacent distribution system. Water services installed prior to watermain testing shall also be purity tested with the water main and all other connections to the new watermain. The second set of purity samples shall be taken 24 hours after ' the first set of samples. A representative background sample of the City water system may be taken from the distribution source at the same time purity samples are taken from the new main. In the event that the Water Section or the Inspector determines that trench water, dirt or debris has entered the new main during construction, the first purity samples shall not be taken until the water has stood in the new main for at least 16 hours after final flushing. As above, the second set of purity samples shall not be taken until the water in the new main has stood for an additional 24 hours. No water shall be flushed during the 16- or 24-hour incubation periods described above, or prior to the purity samples being taken. It shall be the Contractor's responsibility to make arrangements to transport the sample(s) to a state-certified laboratory approved by the Water Section. The Contractor shall be responsible for paying all costs for the purity ' samples. Two (2) consecutive samples, 24 hours apart, must show no coliform presence before performing final connections to the existing water system. The Water Section may be available during normal working hours, depending upon workload, (7:30 am to 4:00 pm), excluding holidays and weekends, to take purity samples, assist with cubing and chlorine injections. The Contractor shall reimburse the City for all associated costs including labor, ' overhead, equipment, and material charges. Outside of normal working hours, the Contractor shall reimburse the City at the most current hourly overtime rate for labor, overhead, equipment and material and any other ' associated charges. The costs shall be based on the latest cost schedule prepared and approved annually by the Engineer. 3.25 PRESSURE AND LEAKAGE TESTS ' All new water mains, extensions of existing mains, water system ' appurtenances and water services larger than 2" shall be pressure tested for leakage in accordance with Section 7-17.3(2) of the WSDOT Standard Specifications.

The guidance document addresses waste generated from stormwater maintenance activities such as street sweeping and the cleaning of catch basins, and to a limited extent, other stormwater conveyance and treatment facilities. Limited information is available on the characteristics of wastes from detention/retention ponds, bioswales,and similar stormwater treatment facilities. The recommendations provided here may be generally applicable to these facilities,with extra diligence given to waste characterization. These recommendations do not constitute rules or regulations, but are suggestions for street waste handling,reuse,and disposal using current regulations and the present state of knowledge of street waste constituents. The recommendations are intended to address the liquid and solid wastes collected during routine maintenance of stonnwatei catch basins, detention/retention ponds and ditches and similar storm water treatment and conveyance structures,and street and parking lot sweeping. In addition to these recommendations, end users and other authorities may have their own requirements for street waste reuse and handling. "Street Wastes" include liquid and solid wastes collected during maintenance of stormwater catch basins, detention/retention ponds and ' ditches and similar storm water treatment and conveyance structures, and solid wastes collected during street and parking tot sweeping. "Street Wastes," as defined here, does not include solids and liquids from street washing using detergents, cleaning of electrical vaults,vehicle wash sediment traps, restaurant grease traps, industrial process waste, sanitary sewage, mixed process, or combined sewage/stormwater wastes. Wastes from oil/water separators at sites that load fuel are not included as street waste. Street waste also does not include flood debris, land slide debris, and chip seal gravel Street waste does not ordinarily classify as dangerous waste. The owner of the stone water facility and/or collector of street waste is considered the waste generator and is responsible for determining whether or not the waste designates as dangerous waste. Sampling to date has shown that material from routine maintenance of sheets and stormwater facilities does not classify as dangerous waste (See Table G.6 below). However, it is possible that street waste from spill sites could classify as February 2005 Volume IV- Source Control BMPs G-1 dangerous waste. Street waste from areas with exceptionally high average daily traffic counts may contain contaminants - such as heavy metals, total petroleum hydrocarbons (TPH), and carcinogenic polycyelic aromatic hydrocarbons (c-PAH) -at levels that limit reuse options. Street Waste Solids Street waste is solid waste. While street waste from normal street and highway maintenance is not dangerous waste, it is solid waste, as defined under The Solid Waste Management Act (Chapter 70 95 RCW) and under Minimum Functional Standards for Solid Waste Handling (Chapter 173-304 WAC). Under the Solid Waste Management Act, local health departments have primary jurisdiction over solid waste management. Street waste solids may contain contaminants at levels too high to allow unrestricted reuse. At the time this document is being prepared, the Minimum Functional Standards are being revised. Chapter 173-304 WAC will be replaced with Chapter 173-350 WAC. "There are currently no specific references in the Minimum Functional Standards to facilities managing street waste solids. These facilities will typically fit under the section dealing with Piles Used for Storage and Treatment(Section 320 of the proposed revisions). There are no specific references for reuse and disposal options for street wastes in the Minimum Functional Standards, although the Minimum Functional Standards do not apply to clean soils. In the proposed rule, clean soils are defined as `soils that do not contain contaminants at concentrations which could degrade the quality of air, waters of the state, soils, or sediments; or pose a thereat to the health of humans or other living organisms' (WAC 173-350-100). Whether or not a soil is a clean soil depends primarily upon the level of contaminants and, to a lesser degree, on the background level of contaminants at a particular ' location and the exposure potential to humans or other living organisms. Therefore, both the soil and potential land application sites must be evaluated to determine if a soil is a clean soil. Local health departments should be contacted to determine if a street waste meets the definition of "clean soil" when it will be reused as a soil There is no simple regulatory mechanism available to classify street waste solids as "clean" for uncontrolled reuse or disposal Local health districts have historically used the Model Toxics Control Act Cleanup Regulation (MTCA) Method A residential soil cleanup levels to approximate 'clean" and to make decisions on land application proposals. These regulations were amended in February 2001. The MTCA regulation is not intended to be directly applied to setting contaminant concentration levels for land application proposals. However, they may provide human health and environmental threat information and a useful framework for such decisions, when used in conjunction with other health and environmental considerations. The local health department should be contacted to determine local requirements for making this determination. G-2 Volume IV- Source Control BMPs February 2005 Using the old MTCA regulations,many local health departments have set a criteria of 200 mg/Kg Total Petroleum Hydrocarbons (TPH) for diesel and heavy fuel oils as a threshold level for clean soil. Using the new MTCA terrestrial ecological evaluation procedures, allowable TPH levels for land I application could range from 200—460, depending on site characteristics and intended land use Street waste sampling has historically yielded TPH values higher than 200 mg/kg for hydrocarbons in the diesel and heavy oil range. These values typically reflect interference from natural organic material and,to a lesser extent,relatively immobile petroleum hydrocarbons. The mobile hydrocarbons that are of concern for ground water protection are generally not retained with street waste solids. Ecology's Manchester Lab has developed an analytical method to reduce the problem of natural organic material being included in the TPH analysis for diesel and heavier range hydrocarbons. This new method, called NWTPH- Dx, reduces the background interference associated with vegetative matter by as much as 85%to 95%. However, even with the new methodology, TPH test results for street waste may still be biased by the presence of natural vegetative material and may still exceed 200 mg/kg. . Where the laboratory results report no `fingerprint' or chromatographic match to known petroleum hydrocarbons,the soils should not be considered to be petroleum contaminated soils.

This is complicated further by analytical interference caused by organic matter that raises practical quantitation or reporting limits. To greatly reduce the level of interference, the use of US EPA Test Method 8270, incorporating the February 2005 Volume IV-Source Control BMPs G-3 silica gel cleanup step, is recommended. The calculated c-PAH value can vary greatly depending upon how non-detect values are handled. The new MICA Method A criterion for c-PAH is 0.1 mg/kg(the sum of all seven c-PAH parameters multiplied by the appropriate toxicity equivalency factor)) for unrestricted land uses. The MTCA criteria for soil cleanup levels for industrial properties is 2.0 mg/kg Following this guidance, most sites where street wastes could be reused as soil will be commercial or industrial sites, or sites where public exposure will be Limited or prevented.

I Under the Solid Waste Management Act, local health departments have primary jurisdiction over solid waste management Street waste handling facilities are subject to the requirements of the Minimal Functional Standards for Solid Waste Handling. The specific requirements will depend upon the manner in which the waste is managed Most facilities will probably be permitted under the section dealing with Piles Used for Storage and Treatment (Section 320 of the proposed revisions) For most facilities,permit requirements include a plan of operation, sampling, record keeping and reporting, inspections, and compliance with other state and local requirements. The plan of operation should include a 1 procedure for characterization of the waste and appropriate reuse and disposal options, consistent with the recommendations in this document and applicable federal, state and local requirements. A street waste site evaluation (see sample at end of this appendix) is suggested for all street waste as a method to identify spill sites or locations that are more polluted than normal. The disposal and reuse options listed below are based on characteristics of routine street waste and are not appropriate for more polluted wastes. The collector of street waste should evaluate it both for its potential to be classified as dangerous waste and to not meet end users requirements. Street waste that is suspected to be dangerous waste should not be collected with other street waste.Material in catch basins with obvious contamination (unusual color, staining, corrosion, unusual odors, fumes, I and oily sheen) should be left in place or segregated until tested. Testing should be based on probable contaminants. Street waste that is suspected to be dangerous waste should be collected and handled by someone experienced in handling dangerous waste. If potential dangerous waste must be collected because of emergency conditions, or if the waste becomes suspect after it is collected, it should be handled and stored separately until a determination as to proper disposal is made. Street waste treatment and storage facilities should have separate "hot load" storage areas for such waste. Dangerous Waste includes street waste]mown and suspected to be dangerous waste. This waste must be handled following the Dangerous Waste Regulations (Chapter 173-303 WAC) unless testing determines it is not dangerous waste. 1 Spills should be handled by trained specialists. Public works maintenance crews and private operators conducting street sweeping or February 2005 Volume IV-Source Control BMPs G-5 cleaning catch basins should have written policies and procedures for dealing with spills or suspected spill materials.Emergency Spill Response telephone numbers should be immediately available as part of these operating policies and procedures. The end recipient of street waste must be informed of its source and may have additional requirements for its use or testing that are not listed here. This document is based primarily on average street waste's chemical constituents and their potential affect on human health and the environment. There are physical constituents (for example, broken glass or hypodermic needles) or characteristics (for example, fine grain size) that could also limit reuse options. Additional treatment such as drying, sorting, or screening may also be required, depending on the needs and requirements of the end user. Street waste treatment and storage facilities owned or operated by governmental agencies should be made available to private waste collectors and other governmental agencies on a cost recovery basis. Proper street waste collection and disposal reduces the amount of waste released to the environment. The operators of street waste facilities should restrict the use of their facilities to certified and/or licensed waste collectors who meet their training and liability requirements. The use,of street waste solids under this guidance should not lead to designation as a hazardous waste site,requiring cleanup under MTCA. Exceeding MTCA Method A unrestricted land use cleanup levels in street waste and products made from street waste, does not automatically make the site where street waste is reused a cleanup site. A site is reportable only if"-a release poses a threat to human health or the environment-" (Model Toxic Control Act). The reuse options proposed below are designed to meet the condition of not posing a threat to human health or the environment. Testing of street waste solids will generally be required as part of a t plan of operation that includes procedures for characterization of the waste. Testing frequency, numbers of samples,parameters to be analyzed, and contaminant limit criteria should all be provided as part of an approved plan of operation. Tables G 4 and G.5 below provide some recommended parameters and sampling frequencies for piles of street waste solids from routine street maintenance. These are provided as guidance only, and are intended to assist the utility and the local health department in determining appropriate requirements. Sampling requirements may be modified, over time, based on accumulated data. When the material is from a street waste facility or an area that has never been characterized by testing, the test should be conducted on a representative sample before co-mingling with other material. Testing in these instances would be to demonstrate that the waste does not designate G-6 Volume IV- Source Control BMPs February 2005 as dangerous waste and to characterize the waste for reuse. At a y minimum, the parameters in Table GA are recommended for these cases. Note that it will generally not be necessary to conduct`1'CLP analyses when the observed values do not exceed the recommended values in Table G.4. Table G.6 illustrates some observed relationships between total metals and TCLP metals values.

For street waste not exceeding the suggested maximum values in Table GA, the following street waste solids reuse and disposal options are recommended: • Street sweepings that consist primarily of leaves, pine needles and branches, and grass cuttings from mowing grassy swales can be composted Litter and other foreign material must be removed prior to composting or the composting facility must provide for such removal as part of the process. The screened trash is solid waste and must be disposed of at an appropriate solid waste handling facility. • Coarse sand screened from street sweeping after recent road sanding, may be reused for street sanding, providing there is no obvious contamination from spills. The screened trash is solid waste and must be disposed of at an appropriate solid waste handling facility. • Roadside ditch cleanings, not contaminated by a spill or other release and not associated with a stormwater treatment system such as a bioswale, may be screened to remove litter and separated into soil and G-8 Volume IV-Source Control BMPs February 2005 vegetative matter(leaves, grass, needles,branches, etc.). The soils from these activities are not generally regulated as solid waste. Ditching material that may be contaminated must be stored, tested and handled in the same manner as other street waste solids. It is the generator's responsibility to visually inspect and otherwise determine whether the materials may be contaminated. • Construction street wastes - solids collected from sweeping or in storm water treatment systems at active construction sites -may be placed back onto the site that generated it, or managed by one on the methods listed below, provided that it has not been contaminated as a result of a spill For concrete handling at construction site, refer to BMP C151 in Volume 11, Construction Stormwater Pollution Prevention. • Screened street waste soils may be used as feedstock materials for topsoil operations. This option should be reserved for street waste soils with very low levels of contaminants. Diluting street waste soils with clean soils or composted material must not be used as a substitute for treatment or disposal. There may be physical contaminants (for example, glass, metal,nails, etc.) in street waste that cannot be entirely screened from the waste Where present, these contaminants in street waste could preclude its use as feedstock material for topsoil 1 operations. • Fill in parks,play fields, golf courses and other recreational settings, where direct exposure by the public is limited or prevented. One way to accomplish is to cover the fill with sod, grass or other capping material to reduce the risk of soil being ingested. The level of contaminants in the street waste must be evaluated to ensure that the soils meet the definition of clean soils when used in this manner. • Fill in commercial and industrial areas, including soil or top dressing for use at industrial sites, roadway medians, airport infields and similar sites,where there is limited direct human contact with the soil, and the soils will be stabilized with vegetation or other means. The level of contaminants in the street waste must be evaluated to ensure that the sods meet the definition of clean soils when used in this manner. • Top dressing on roadway slopes, road or parking lot construction material and road subgrade, parking lot subgrade, or other road fill. The level of contaminants in the street waste must be evaluated to ensure that the soils meet the definition of clean soils when used in this manner. • Daily cover or fill in a permitted municipal solid waste landfill,provided the street waste solids have been dewatered Street waste solids may be acceptable as final cover during a landfill closure The local health department and landfill operator should be consulted to determine conditions of acceptance. • Treatment at a permitted contaminated soil treatment facility. IFebruary 2005 Volume IV-Source Control BMPs G-9 i • Recycling through incorporation into a manufactured product, such as Portland cement, prefab concrete, or asphalt The facility operator should be consulted to determine conditions of acceptance. • Other end-use as approved by the local health department • Disposal at an appropriate solid waste handling facility. For street waste that exceed the suggested maximum values in Table GA, the following street waste solids reuse and disposal options are recommended: • Treatment at a permitted contaminated soil treatment facility. • Recycling through incorporation into a manufactured product, such as Portland cement,prefab concrete, or asphalt. The facility operator should be consulted to determine conditions of acceptance. • Other end-use as approved by the local health department • Disposal at an appropriate solid waste handling facility. Street Waste Liquids Street waste collection should emphasize solids in preference to liquids. Street waste solids are the principal objective in street waste collection and are substantially easier to store and treat than liquids. Street waste liquids require treatment and/or must follow location limitations before their discharge. Street waste liquids usually contain high amounts of suspended and total solids and adsorbed metals. Treatment requirements depend on the discharge location Discharges to sanitary sewer and storm sewer systems must be i approved by the entity responsible for operation and maintenance of the system. Ecology will not generally require waste discharge permits for discharge of stormwater decant to sanitary sewers or to stormwater treatment BIv1Ps constructed and maintained in accordance with Ecology's Stormwater Management Manual for Western Washington (See Volume 5 for further detail). The following disposal options are recommended, in order of preference, for catch basin decant liquid and for water removed from stormwater treatment facilities. Under the Municipal General Permit, municipalities are required to use this guidance in determining appropriate means of dealing with street wastes from stormwater maintenance activities. Your regional ' Department of Ecology water quality staff can help you with treatment standards and permit requirements for your particular situation. G-10 Volume IV-Source Control BMPs February 2005 Discharge of catch basin decant liquids to a municipal sanitary sewer connected to a Public Owned Treatment Works (POTW) is the preferred disposal option. Discharge to a municipal sanitary sewer requires the approval of the sewer authority. Street waste liquids discharged to a POTW may be treated at a combined street waste liquid and solid facility (decant facility) or at separate liquids only facilities. These liquid only facilities may consist of modified type 2 catch basins (with a flow restrictor or oil/water separator) or water quality vaults, strategically located through the sanitary collection system. These should provide 24-hour detention for the expected volumes and should be constructed and operated to ensure that the decant discharge does not resuspend sediments. Sewer authorities should require periodic sampling and decant facility operators should test their waste effluent on a regular basis, but street waste decant liquid should meet the most restrictive local limits with 24 hours of undisturbed gravity settling. Overnight settling is more practical and will likely meet most local pretreatment requirements (See Table G.9 Catch Basin Decant Values Following Settling for typical catch basin decant values from King County's decant facility at Renton). State and local regulations generally prohibit discharge of stormwater runoff into sanitary sewers, to avoid hydraulic overloads and treatment performance problems. The volume of storm water discharged from catch basins and small stormwater treatment facilities is generally not sufficient 1 to be a problem, provided the discharge point is properly selected and designed. Stormwater removed from catch basins and stormwater treatment wetvaults may be discharged into a Basic or Enhanced Stormwater Treatment BMP. L Decant liquid collected from cleaning catch basins and stormwater treatment wetvaults may be discharged back into the storm sewer system under the following conditions: • The preferred disposal option of discharge to sanitary sewer is not reasonably available, and • The discharge is to a Basic or Enhanced Stormwater Treatment Facility (See Volume V, Chapters 3 and 4), and • The storm sewer system owner/operator has granted approval and has determined that the treatment facility will accominodate the increased loading. IPretreatment may be required to protect the treatment BMP. Reasonably available will be determined by the stormwater utility and by the circumstances, including such factors as distance, tirne of travel, load restrictions, and capacity of the stormwater treatment facility. Some jurisdictions may choose not to allow discharge back to the storm sewer February 2005 Volume IV-Source Control BMPs G-11 i 1 system. Currently King County does not allow such discharges, under King County Code 9.12—Water Quality. Discharge back into the storm sewer is an acceptable option, under certain conditions: • Other practical means are not reasonably available, and • Pretreatment is provided by discharging to a modified type 2 catch basin(with a flow restrictor or oil/water separator) or water quality vault, and • The discharge is upstream of a basic or enhanced stormwater treatment , BMP, and • The storm sewer system owner/operator has granted approval. Other practical means includes the use of decanting facilities and field decant sites that discharge to sanitary sewers or discharge to an approved stormwater treatment BMP. Limited field testing of flocculent aids has been conducted. While the use of flocculent aids is promising, sufficient testing has not been conducted to allow approval of any specific product or process In general, the following conditions must be met for flocculent use to be approved: • The flocculent must be non-toxic under circumstances of use and approved for use by the Department of Ecology • The decant must be discharged to an approved basic or enhanced stormwater treatment BMP, with sufficient capacity and appropriate design to handle the anticipated volume and pollutant loading • The discharge must be approved by the storm sewer system owner/operator. Water removed from stormwater ponds,vaults and oversized catch basins may be returned to storm sewer system. Stormwater ponds, vaults and oversized catch basins contain substantial amounts of liquid, which hampers the collection of solids and pose problems if the removed waste must be hauled away from the site Water removed from these facilities may be discharged back into the pond,vault or catch basin provided: ' • Cleai water removed from a stormwater treatment structure may be discharged directly to a downgradient cell of a treatment pond or into the storm sewer system • Turbid water may be discharged back into the structure it was removed from if G-12 Volume 1V_-Source Control BMPs February 2005 i I the removed water has been stored in a clean container(eductor truck,Baker tank or other appropriate container used specifically for handling stormwater or clean water)and there will be no discharge from the treatment structure for at least 24 hours. • The discharge must be approved by the storm sewer system owner/operator. Vegetation management and structural integrity concerns sometimes require that the ponds be refilled as soon after solids removal as possible. For ponds and other systems relying on biological processes for waste treatment, it is often preferable to reuse at least some portion of the removed water. 1 Table G.7 -Typical Catch Basin Decant Values Compared to Surface Water Quality Criteria PARAMETER State Surface Water Quality Criteria Range of Values Range of Values Reported Reported METALS Freshwater Acute Freshwater Chronic Total Metals(ug/1) Dissolved Metals (ug/1—dissolved (ug/I—dissolved (ug/1) metals) metals 1 Arsente 360 190 100—43000 60- 100 Cadmium* 273 084 64-2400 2-5 Chromium(total) 13 --90000 3-6 Chromium 111 * 435 141 I Chromium VI 05 10 Copper* 13.04 892 81 --200000 3-66 Lead* 473 1 85 255--230000 1 -50 Nickel* 1114 124 1 40 --330 20- 80 Zmc* 90 1 823 1 401 --440000 1 1900-61000 Mercury 1 210 1 012 1 0 5 --21 9 *Hardness dependent,hardness assmned to be 75 mg/1 February 2005 Volume 1V-Source Control BMPs G-13 Table G.8 -Typical Values for Conventional Pollutants in Catch Basin Decant PARAMETER Ecology 1993 (Min-Max) King County (Min-Max) 1995 Values as mg/l;except where Mean Mean stated H 694 618-798 8 6.18- 1125 Conductive umhos/cm 364 184- 1110 480 129- 10,100 Hardness (mg/1 CaCO3 234 73 - 762 Fecal Coliform(MPN/100 ml) 3000 BOD 151 28- 1250 COD 900 120-26,900 Oil&Grease 11 7 0-40 471 15-6242 TOC 136 49-7880 3670 203 -30,185 Total Solids 1 1930 586-70,400 Total Dissolved Solids 212 95-550 Total Suspended Solids 2960 265- 111,000 Settleable Solids ml/l/hr 27 2-234 57 1 -740 Turbid (ntu) 1000 55-52,000 4673 43 -78,000 Table G.9 - Catch Basin Decant Values Folio win Settlin i Parameter;Total Metals Portland—Inverness Site King County-Renton METRO Pretreatment in mg/1 Min-Max Min-Max Discharge Limits Arsenic 0027 015 <MDL—0 12 4 Cadmium .0009- 0150 <MDL—0 11 06 Chromium 0046- 0990 017— 189 5 Copper .015 - 8600 0501— 408 8 Lead 050—6 60 152—2 83 4 Nickel 0052- 10 056- 187 5 Silver 0003 - 010 <MDL 3 Zinc 130—1 90 .152—3.10 10 Settleable Solids;ml/L No Data 02-2 7 , Nonpolar FOG 5 7-25 5-22 100 Ph(std) 6.1-72 674-826 50- 12.0 TSS 28- 1310 Recorded Total Monthly Data not available 31,850- 111,050 Flow,Gallons Recorded Max Daily Data not available 4,500- 18,600 25,000 GPD Flow,Gallons Calculated Average Daily Data not available 1517-5428 Flow,GPD 1)Data from King County's Renton Facility(data from 1998—199)and the City of Portland's Inverness Site(data from 1999—2001),detention times not provided G-14 Volume IV-Source Control BMPs February 2005 Site Evaluation A site evaluation is suggested as method to identify spill sites or locations that are more polluted than normal. The site evaluation will aid in determining if waste should be handled as dangerous waste and in determining what to test for if dangerous waste is suspected. The site evaluation will also help to determine if the waste does not meet the requirements of the end users. There are three steps to a site evaluation: 1. An historical review of the site for spills, previous contamination and 1 nearby toxic cleanup sites and dangerous waste and materials. The historical review will be easier if done on an area wide basis prior to scheduling any waste collection. The historical review should be more thorough for operators who never collected waste at a site before. At a minimum, the historical review should include operator knowledge of the area's collection history or records kept from previous waste collections. Private operators should ask the owner of the site for records of previous contamination and the timing of the most recent cleaning. Ecology's Hazardous Substance Information Office maintains a Toxic Release Inventory and a"Facility Site" webpage,tracking more than 15,000 sites. This information is available through the Internet at http•//www wa.gov/ecology/iss/fsweb/fshome.htmi or by calling a toll- free telephone number(800-633-7585). The webpage allows anyone with web-access to search for facility information by address, facility name,town, zip code, and SIC code, etc. It lists why the Department of Ecology is tracking each one (NPDF,S, TSCA, RCRA, Clean Air I Act, etc.), as well as who to call within Ecology to find out more about the given facility. I 2. An area visual inspection for potential contaminant sources such as a past fire, leaking tanks and electrical transformers, and surface stains. ' The area around the site should be evaluated for contaminant sources prior to collection of the waste. The area visual inspection may be done either as part of multiple or as single site inspections. If a potential contaminant source is found, the waste collection should be delayed until the potential contaminant is assessed. A second portion of the area visual inspection is a subjective good housekeeping evaluation of the area. Locations with poor housekeeping commonly cut corners in less obvious places and should February 2005 Volume !V-Source Control BMPs G-15 be inspected in greater detail for illegal dumping and other contamination spreading practices. 3. A waste and container inspection before and during collection. The inspection of the waste and catch basin or vault is the last and perhaps most critical step in the site evaluation. For example, if the stormwater facility has an unusual color in or around it, then there is a strong possibility that something could have been dumped into it Some colors to be particularly wary of are yellow-green from antifreeze dumping and black and/rainbow sheen from oil and/or grease dumping. In addition, if any staining or corrosion is observed, then a solvent may have been dumped. Fumes are also good indicators of potential dangerous or dangerous waste. Deliberate smelling of catch basins should be avoided for worker safety, but suspicious odors may be encountered from catch basins thought to be safe. Some suspicious odors are rotten eggs (hydrogen sulfide is present), gasoline or diesel fumes, or solvent odors. If unusual odors are noted, contact a dangerous waste inspector before cleaning the basin. Finally, operator experience is the best guide to avoid collection of contaminated waste i 1 1 t G-16 Volume IV- Source Control BMPs February 2005 r Resource Materials — Management of Street Wastes Austin, City of, Removal Efficiencies of Stormwater Control Structures.
