The physical completion of all remaining work in the remaining contract 5 time. 6 7 Unresolved requests for time extensions shall be reflected in the Schedule Update 8 by assuming no time extension will be granted, and by showing the effects to 9 follow-on activities necessary to physically complete the project within the currently 10 authorized time for completion. 11 12 1-08.3(4) Measurement 13 No specific unit of measurement shall apply to the lump sum item for Type B 14 Progress Schedule. 15 16 1-08.3(5) Payment 17 Payment will be made in accordance with Section 1-04.1, for the following bid item 18 when it is included in the proposal: 19 20 "Type B Progress Schedule", lump sum. 21 22 The Lump Sum price shall be full pay for all costs for furnishing the Type B 23 Progress Schedule and preliminary Type B Progress Schedule. 24 25 Payment of 80 percent of the lump sum price will be made upon approval of the 26 Progress Schedule. 27 28 Payment will be increased to 100 percent of the lump sum price upon completion of 29 80 percent of the original total contract award amount. 30 31 All costs for providing Type A Progress Schedules and Weekly Look-Ahead 32 Schedules are considered incidental to other items of work in the contract. 33 34 No payment will be made for Schedule Updates that are required due to the 35 Contractors operations. Schedule Updates required by events that are attributed to 36 the actions of the Contracting Agency will be paid for in accordance with Section 1- 37 09.4. 38 39 1-08.4 Prosecution of Work 40 The first sentence is revised to read: 41 42 The Contractor shall begin work within 21 calendar days from the date of execution of 43 the contract by the Contracting Agency, unless otherwise approved in writing. 44 45 1-08.5 Time for Completion 46 This section is revised to read: 47 48 The Contractor shall complete all physical contract work within the number of "working 49 days" stated in the Contract Provisions or as extended by the Engineer in accordance 50 with Section 1-08.8. Every day will be counted as a "working day" unless it is a 51 nonworking day or an Engineer determined unworkable day. A nonworking day is 52 defined as a Saturday, a Sunday, a whole or half day on which the contract specifically TEST2 7 1 prohibits work on the critical path of the Contractor's approved progress schedule, or 2 one of these holidays: January 1, the third Monday of January, the third Monday of 3 February, Memorial Day, July 4, Labor Day, November 11, Thanksgiving Day, the day 4 after Thanksgiving, and Christmas Day. When any of these holidays fall on a Sunday, 5 the following Monday shall be counted a nonworking day. When the holiday falls on a 6 Saturday, the preceding Friday shall be counted a nonworking day. The days between 7 December 25 and January 1 will be classified as nonworking days. 8 9 An unworkable day is defined as a half or whole day the Engineer declares to be 10 unworkable because of weather or conditions caused by the weather that prevents 11 satisfactory and timely performance of the work shown on the critical path of the 12 Contractor's approved progress schedule. Other conditions beyond the control of the 13 Contractor may qualify for an extension of time in accordance with Section 1-08.8. 14 15 Contract time shall begin on the first working day following the 21st calendar day after 16 the date the Contracting Agency executes the contract. If the Contractor starts work on 17 the project at an earlier date, then contract time shall begin on the first working day 18 when onsite work begins. The contract provisions may specify another starting date for 19 contract time, in which case, time will begin on the starting date specified. 20 21 Each working day shall be charged to the contract as it occurs, until the contract work is 22 physically complete. If substantial completion has been granted and all the authorized 23 working days have been used, charging of working days will cease. Each week the 24 Engineer will provide the Contractor a statement that shows the number of working 25 days: (1) charged to the contract the week before; (2) specified for the physical 26 completion of the contract; and (3) remaining for the physical completion of the contract. 27 The statement will also show the nonworking days and any half or whole day the 28 Engineer declares as unworkable. Within 10 calendar days after the date of each 29 statement, the Contractor shall file a written protest of any alleged discrepancies in it. 30 To be considered by the Engineer, the protest shall be in sufficient detail to enable the 31 Engineer to ascertain the basis and amount of time disputed. By not filing such detailed 32 protest in that period, the Contractor shall be deemed as having accepted the statement 33 as correct. 34 35 The Engineer will give the Contractor written notice of the physical completion date for 36 all work the contract requires. That date shall constitute the physical completion date of 37 the contract, but shall not imply the Secretary's acceptance of the work or the contract. 38 39 The Engineer will give the Contractor written notice of the completion date of the 40 contract after all the Contractor's obligations under the contract have been performed by 41 the Contractor. The following events must occur before the Completion Date can be 42 established: 43 44 1. The physical work on the project must be complete; and 45 46 2. The Contractor must furnish all documentation required by the contract and 47 required by law, to allow the Contracting Agency to process final acceptance of 48 the contract. The following documents must be received by the Project 49 Engineer prior to establishing a completion date: 50 51 a. Certified Payrolls (Federal-aid Projects) 52 b. Material Acceptance Certification Documents TEST2 8 w 1 c. Annual Report of Amounts Paid as MBE/WBE Participants or 2 Quarterly Report of Amounts Credited as DBE Participation, as 3 required by the Contract Provisions. 4 d. FHWA 47 (Federal-aid Projects) 5 e. Final Contract Voucher Certification 6 7 1-08.8 Extensions of Time 8 Section 1-08.8 is revised to read: 9 10 The Contractor shall submit any requests for time extensions to the Engineer in writing 11 no later than 10 working days after the delay occurs. The requests for time extension 12 shall be limited to the affect on the critical path of the Contractor's approved schedule 13 attributable to the change or event giving rise to the request. 14 15 To be considered by the Engineer, the request shall be in sufficient detail (as determined 16 by the Engineer) to enable the Engineer to ascertain the basis and amount of the time 17 requested. The request shall include an updated schedule that supports the request 18 and demonstrates that the change or event: (1) had a specific impact on the critical 19 path, and except in cases of concurrent delay, was the sole cause of such impact, and 20 (2) could not have been avoided by resequencing of the work or by using other 21 reasonable alternatives. If a request combined with previous extension requests, 22 equals 20 percent or more of the original contract time then the Contractor's letter of 23 request must bear consent of Surety. In evaluating any request, the Engineer will 24 consider how well the Contractor used the time from contract execution up to the point 25 of the delay and the effect the delay has on any completion times included in the special 26 provisions. The Engineer will evaluate and respond within 15 calendar days of 27 receiving the request. 28 29 The authorized time for physical completion will be extended for a period equal to the 30 time the Engineer determines the work was delayed because of: 31 32 1. Adverse weather causing the time requested to be unworkable, provided that 33 the Engineer had not already declared the time to be unworkable and the 34 Contractor has filed a written protest according to Section 1-08.5. 35 36 2. Any action, neglect, or default of the Contracting Agency, its officers, or 37 employees, or of any other contractor employed by the Contracting Agency. 38 39 3. Fire or other casualty for which the Contractor is not responsible. 40 41 4. Strikes. 42 43 5. Any other conditions for which these Specifications permit time extensions 44 such as: 45 46 a. In Section 1-04.4 if a change increases the time to do any of the work 47 including unchanged work. 48 49 b. In Section 1-04.5 if increased time is part of a protest that is 50 found to be a valid protest. 51 TEST2 9 1 c. In Section 1-04.7 if a changed condition is determined to exist that 2 caused a delay in completing the contract. 3 4 d. In Section 1-05.3 if the Contracting Agency does not approve properly 5 prepared and acceptable drawings within 30 calendar days. 6 7 e. In Section 1-07.13 if the performance of the work is delayed as a 8 result of damage by others. 9 10 f. In Section 1-07.17 if the removal or the relocation of any utility by 11 forces other than the Contractor caused a delay. 12 13 g. In Section 1-07.24 if a delay results from all the right of way 14 necessary for the construction not being purchased and the special 15 provisions does not make specific provisions regarding unpurchased 16 right of way. 17 18 h. In Section 1-08.6 if the performance of the work is suspended, 19 delayed, or interrupted for an unreasonable period of time that proves 20 to be the responsibility of the Contracting Agency. 21 22 i. In Section 1-09.11 if a dispute or claim also involves a delay in 23 completing the contract and the dispute or claim proves to be valid. 24 25 j. In Section 1-09.6 for work performed on a force account basis. 26 27 6. If the actual quantity of work performed for a bid item was more than the 28 original plan quantity and increased the duration of a critical activity. 29 Extensions of time will be limited to only that quantity exceeding the original 30 plan quantity. 31 32 7. Exceptional causes not specifically identified in items 1 through 6, provided the 33 request letter proves the Contractor had no control over the cause of the delay 34 and could have done nothing to avoid or shorten it. 35 36 Working days added to the contract by time extensions, when time has overran, shall 37 only apply to days on which liquidated damages or direct engineering have been 38 charged, such as the following: 39 40 If substantial completion has been granted prior to all of the authorized working 41 days being used, then the number of days in the time extension will eliminate an 42 equal number of days on which direct engineering charges have accrued. If the 43 substantial completion date is established after all of the authorized working days 44 have been used, then the number of days in the time extension will eliminate an 45 equal number of days on which liquidated damages or direct engineering charges 46 have accrued. 47 The Engineer will not allow a time extension for any cause listed above if it resulted 48 from the Contractor's default, collusion, action or inaction, or failure to comply with 49 the contract. 50 The Contracting Agency considers the time specified in the special provisions as 51 sufficient to do all the work. For this reason, the Contracting Agency will not grant a 52 time extension for: TEST2 10 1 2 • Failure to obtain all materials and workers unless the failure was the result of 3 exceptional causes as provided above in subsection 7; 4 5 0 Changes, protests, increased quantities, or changed conditions (Section 1-04) 6 that do not delay the completion of the contract or prove to be an invalid or 7 inappropriate time extension request; 8 9 0 Delays caused by nonapproval of drawings or plans as provided in Section 10 1-05.3; 11 12 0 Rejection of faulty or inappropriate equipment as provided in Section 1-05.9; 13 14 Correction of thickness deficiency as provided in Section 5-05.5(1)6. 15 16 The Engineer will determine whether the time extension should be granted, the reasons 17 for the extension, and the duration of the extension, if any. Such determination will be 18 final as provided in Section 1-05.1. 19 20 SECTION 1-09, MEASUREMENT AND PAYMENT 21 December 4, 2006 22 1-09.6 Force Account 23 The last paragraph under "3. For Equipment" is revised to read: 24 25 Copies of the AGC/WSDOT Equipment Rental Agreement will be maintained on the 26 Contracting Agency's web site at www.wsdot.wa.gov. 27 28 1-09.9(1) Retainage 29 The fourth paragraph is revised to read: 30 31 Release of the retainage will be made 60 days following the Completion Date (pursuant 32 to RCW 39.12, and RCW 60.28) provided the following conditions are met: 33 34 1. On contracts totaling more than $20,000, a release has been obtained from the 35 Washington State Department of Revenue. 36 37 2.

Preserving Rock Below Subgrade. The Contractor shall take care not to break 10 down, loosen, or damage the rock under the subgrade line, except as provided by 11 Section 2-03.3(3). Normally cuts will be made from the top, lift by lift, to protect the 12 rock bench that will remain. The Contractor shall be responsible for methods used 13 and for any damage caused to the roadbed, regardless of any previous approvals 14 by the Engineer. 15 16 2. Scaling and Dressing. To leave rock cuts in a safe, stable condition, the 17 Contractor shall scale and dress them, removing all loose fragments and rocks not 18 firmly fastened to the rock slope. The Contractor shall also remove any 19 overhanging rock the Engineer sees as a hazard to roadway users. 20 21 If the Engineer requires it, the Contractor shall remove loose fragments and rocks 22 lying outside the slope stakes. Payment for such extra work shall be by force 23 account as provided in Section 1-09.6. The Contracting Agency will pay for loading 24 and hauling these materials at the unit contract prices that apply or as provided in 25 Section 1-04.4. 26 27 3. Drilling and Blasting. Not less than two weeks prior to commencing drilling and 28 blasting operations or at any time the Contractor proposes to change the drilling 29 and blasting methods, the Contractor shall submit a blasting plan to the Engineer 30 for review. The blasting plan shall contain the full details of the drilling and blasting 31 patterns and controls the Contractor proposes to use for both the controlled and 32 production blasting. The blasting plan submittal is required for all blasting 33 operations and shall contain the following minimum information: 34 35 a) Station limits of proposed shot. 36 37 b) Plan and section views of proposed drill pattern including free face, 38 burden, blast hole spacing, blast hole diameter, blast hole angles, lift 39 height, and subdrill depth. 40 +�41 c) Loading diagram showing type and amount of explosives, primers, 42 initiators, and location and depth of stemming. 43 44 d) Initiation sequence of blast holes including delay times and delay system. 45 46 e) Manufacturer's data sheets for all explosives, primers, and initiators to be 47 employed. 48 49 Review of the blasting plan by the Engineer shall not relieve the Contractor of the 50 responsibility for the accuracy and adequacy of the plan when implemented in the 51 field. TEST2 12 1 2 When blasting to establish slopes 1/2 to 1 or steeper, and more than 10 feet high, 3 the Contractor shall use controlled blasting. The Engineer may require the 4 Contractor to use controlled blasting to form the faces of other slopes, even if the 5 slopes could be formed by nonblasting methods. 6 7 Controlled blasting refers to the controlled use of explosives and blasting 8 accessories in carefully spaced and aligned drill holes to provide a free surface or 9 shear plane in the rock along the specified backslope. Controlled blasting 10 techniques covered by this specification include presplitting and cushion blasting. 11 12 In addition to the blasting plan submittal, when using controlled blasting the 13 Contractor shall: 14 15 a) Prior to commencing full-scale blasting operations, the Contractor shall 16 demonstrate the adequacy of the proposed blast plan by drilling, blasting, 17 and excavating short test sections, up to 100 feet in length, to determine 18 which combination of method, hole spacing, and charge works best. 19 When field conditions warrant, the Contractor may be ordered to use test 20 section lengths less than 100 feet. 21 22 Unless otherwise approved by the Engineer, the Contractor shall begin the 23 tests with the controlled blast holes spaced 30-inches apart, then adjust if 24 needed, until the Engineer approves the spacing to be used for full-scale 25 blasting operations. 26 27 b) The Contractor shall completely remove all overburden soil and loose or 28 decomposed rock along the top of the excavation for a distance of at least 29 30 feet beyond the end of the production hole drilling limits, or to the end 30 of the cut, before drilling the presplitting holes. 31 32 c) The controlled blast holes shall be not less than 21/2 inches nor more than 33 3 inches in diameter. 34 35 d) The Contractor shall control drilling operations by the use of the proper 36 equipment and technique to ensure that no hole shall deviate from the 37 plane of the planned slope by more than 9 inches either parallel or normal 38 to the slope. Drill holes exceeding these limits shall not be paid for unless 39 satisfactory slopes are being obtained. 40 41 e) Controlled blast holes shall extend a minimum of 30 feet beyond the limits 42 of the production holes to be detonated, or to the end of the cut as 43 applicable. 44 45 f) The length of controlled blast holes for any individual lift shall not exceed 46 20 feet unless the Contractor can demonstrate to the Engineer the ability 47 to stay within the above tolerances and produce a uniform slope. If 48 greater than 5 percent of the presplit holes are misaligned in any one lift, 49 the Contractor shall reduce the height of the lifts until the 9-inch alignment 50 tolerance is met. Upon satisfactory demonstration, the length of holes 51 may be increased to a maximum of 60 feet with written approval of the 52 Engineer. TEST2 13 1 1 2 g) When the cut height requires more than one lift, a maximum 2-foot offset 3 between lifts will be permitted to allow for drill equipment clearances. The 4 Contractor shall begin the control blast hole drilling at a point that will a 5 allow for necessary offsets and shall adjust, at the start of lower lifts, to 6 compensate for any drift that may have occurred in the upper lifts. 7 8 h) Before placing charges, the Contractor shall determine that the hole is free 9 of obstructions for its entire depth. All necessary precautions shall be 10 exercised so that the placing of the charges will not cause caving of 11 material from the walls of the holes. 12 13 i) The maximum diameter of explosives used in presplit holes shall not be 14 greater than '/z the diameter of the presplit hole. 15 16 j) Only standard explosives manufactured especially for controlled blasting 17 shall be used in controlled blast holes, unless otherwise approved by the 18 Engineer. Bulk ammonium nitrate and fuel oil (ANFO) shall not be allowed 19 to be loaded in the presplit holes. 20 21 k) If fractional portions of standard explosive cartridges are used, they shall 22 be firmly affixed to the detonating cord in a manner that the cartridges will 23 not slip down the detonating cord nor bridge across the hole. Spacing of 24 fractional cartridges along the length of the detonating cord shall not 25 exceed 30 inches center to center and shall be adjusted to give the 26 desired results. 27 28 1) Continuous column cartridge type of explosives used with detonating cord 29 shall be assembled and affixed to the detonating cord in accordance with 30 the explosive manufacturer's instructions, a copy of which shall be 31 furnished to the Engineer. 32 33 m) The bottom charge of a presplit hole may be larger than the line charges 34 but shall not be large enough to cause overbreak. The top charge of the 35 presplitting hole shall be placed far enough below the collar, and reduced 36 sufficiently, to avoid overbreaking and heaving. 37 38 n) The upper portion of all presplit holes, from the top most charge to the 39 hole collar, shall be stemmed. Stemming materials shall be sand or other 40 dry angular material, all of which passes a 3/8-inch sieve. 41 42 0) If presplitting is specified, the detonation of these holes shall be fired first. 43 44 p) If cushion blasting is specified, the detonation of these holes shall be fired 45 last on an instantaneous delay after all other blasting has taken place in i 46 the excavation. 47 48 q) Production blast holes shall not be drilled closer than 6 feet to the 49 controlled blast line, unless approved by the Engineer. The bottom of the 50 production holes shall not be lower than the bottom of the controlled blast 51 holes. Production holes shall not exceed 6 inches in diameter, unless TEST2 14 w 1 approved by the Engineer. Detonation of production holes shall be on a 2 delay sequence toward a free face. 3 4 r) The use of horizontal blast holes for either production or controlled 5 blasting is prohibited. 6 7 SECTION 2-09, STRUCTURE EXCAVATION 8 January 3, 2006 9 2-09.3(1)E Backfilling 10 Item 1 of the first paragraph under Compaction is revised to read: 11 12 1.

(HWA) for the planned replacement of the Renton Village storm sewer system, located between South Grady Way and 1-405, in the City of Renton, Washington. The project location is indicated on Figure 1. The objective of our work was to investigate subsurface soil and ground water conditions,and provide geotechnical recommendations for design and construction of the replacement storm sewer system. 1.2 PROJECT DESCRIPTION The project will replace two sections of existing pipe; a 440-foot long 42-inch concrete pipe, followed by a 220-foot long 48-inch corrugated metal pipe(CMP)culvert. The 42-inch pipe drains from an existing 72-inch pipe within the driveway just southeast of the Thriftway store in the Renton Village complex. The existing CMP discharges stormwater to a small stream (Rolling Hills Creek) at the south side of the One Renton Place(office building)parking lot, immediately north of 1-405. The existing and proposed storm sewer alignments,together with exploration locations,are shown on the Site and Exploration Plan, Figure 2. Presently, the invert elevations of the existing lines at inlet and outlet ends are understood to be of the order of 21 and 19 feet,respectively. Corrosion of the existing CMP at the outfall and collapse of the end of the pipe destroyed two parking spaces and left a portion of the existing culvert exposed, about two years ago. At the catch basin in the parking lot,which is the juncture of the concrete and CMP sections,we understand that the invert elevation of the 48-inch CMP is about 17.61 feet,while the invert elevation at the outfall is about 19.39 feet, giving the CMP a negative slope. The difference .. in elevations suggests that the catch basin has settled at least 1.78 feet. Based on information provided to date,we understand the City plans to remove the existing .. storm sewer and replace it with a larger culvert. The preferred and alternate alignments as determined before the geotecluucal exploration are shown on Figure 2. Based on the exploration data provided in the draft and final reports, a second alternative alignment close to the One Renton Place building was considered. To evaluate subsurface conditions along the second alternative alignment,three additional borings were advanced in December 2006. aw January 12,2007 ' HWA Project No. 2006-067-21 Based on the subsurface conditions encountered in the additional borings,we understand the original alignment remains the preferred. The preferred pipeline, as proposed by Gray&Osborne, Inc. (G&O), is a 4-sided, prefabricated concrete,box culvert, with dimensions of either 4 by 6 or 4 by 8 feet. It will consist of either an integral box section, or an inverted U-section set on a prefabricated concrete base. Alternatively,the existing culvert may be replaced with twin 48-inch diameter concrete pipes. Although design details of the new culvert are still in progress, we understand that the invert elevation will be of the order of 6 to 8 feet below existing grades. Based on existing ground elevations,this would provide for culvert invert elevations of approximately 21 feet at the upstream end,decreasing to approximately 19 feet at the outfall end. After culvert replacement,the asphaltic concrete pavement grades will be restored to approximately the existing ones. A new outfall area will be constructed and the lost parking spots restored. 1.3 SCOPE OF SERVICES AND AUTHORIZATION Our work was conducted in accordance with our Project Cost Estimate, submitted to Mr.Barry Baker,of G&O,on October 17,2005. Verbal authorization to proceed was given by Mr.Barry Baker on May 15,2006. Our initial scope of work included performing four exploratory boreholes at the site, installing two piezometer wells,slug testing and hydrogeological analysis,laboratory testing, geotechnical engineering analyses,and providing , geotechnical recommendations for the proposed replacement culvert. Additional work was authorized on December 5, 2006,per our scope and cost estimate of the same date, and included drilling three additional boreholes along an alternative alignment, consolidation testing of a peat sample and settlement analyses,and revision of the previously submitted final report. 2.0 FIELD AND LABORATORY INW4 STIGATIONS 2.1 FIELD INVESTIGATION We drilled four test boreholes along the proposed aliglunent on June 2ud and 13`x',2006. , Three additional boreholes were drilled on December 8, 2006. The boreholes were designated BH-1 through BH-7,whose approximate locations are shown on the Site and Exploration Plan, Figure 2. Borehole BH-2A was attempted beyond the east side of a high- voltage transmission line,but was terminated at 6.5 feet due to a hard obstruction(later determined to be an unmarked utility vault that was never used). To monitor ground water conditions, we installed slotted standpipe piezometers in boreholes BH-1 and BH-4. Ground water readings were taken on June 16,2006,and again on June 23, 2006-067 Rev Finalldoc 2 I IWA GLOSCir-�NcFs INC. MW January 12, 2007 m HWA Project No. 2006-067-21 aw 2006,to determine stabilized water table conditions. Slug testing in the piezometers was also performed on June 23, 2006. Field exploration methods are described in more detail,and summary borehole logs and ground water results are presented in Appendix A. 2.2 LABORATORY TESTING Laboratory tests were conducted on selected samples obtained from the boreholes to characterize relevant engineering properties of the site soils. Laboratory tests initially included determination of in-situ moisture content,particle size analyses,Atterberg Limits, and organic content of subsurface soil deposits where appropriate. During the second phase of investigation,an undisturbed sample of the peat deposit was obtained to permit consolidation testing for purposes of refining settlement estimates related to construction of the new stormwater conveyance system. The tests were conducted in general accordance with appropriate American Society of Testing and Materials(ASTM)Standards,and are discussed in further detail in Appendix B. The results are presented hi Appendix B,or are displayed on the exploratory logs in Appendix A. 3.0 GEOLOGIC AND SUBSURFACE CONDITIONS 3.1 SURFACE CONDITIONS The ground surface along the storm sewer alignment is relatively flat,sloping gently to the south at elevations ranging from approximately 26 to 30 feet. The ground surface along the alignment consists of paved parking lots on both sides of South Renton Village Place. The existing parking lot pavements are in good condition, aside from settlements experienced at the south end of the site, and settlement in the vicinity of the existing catch basin r. approximately 225 feet north of the south edge of the parking lot. Also,most of the parking lot south of Renton Village Place appears broadly down-warped, with scattered long pavement cracks existing in areas within which the boreholes encountered peat. Pavement damage at the south edge of the parking lot includes the erosion and loss of two parking spaces and the exposure of part of the existing CMP storm sewer culvert. In addition to the storm sewer,there are significant underground utilities in the project area,including sanitary sewer lines,water mains, telephone and natural gas. .. Water from the current storm sewer system is discharged into a drainage ditch/stream on the south end of the site. The amount of water discharged is variable and depends on local precipitation conditions. During a heavy rain storm,the water discharging from the storm sewer system was observed as high as a few inches from the top of the exposed culvert. aw 2006-067 Rev FinaMdoc 3 HWA GEOSCIENCES INC. TAW r January 12,2007 HWA Project No. 2006-067-21 3.2 GENERAL GEOLOGY Geologic information for the site was obtained from the Geologic Map of the Renton Quadrangle, King County, Washington(Mullineaux,D. R., 1965). This map indicates that there are three surficial geologic units crossed by the storm system. From north to south, these consist of the following: 1) Quaternary recessional glaciolacustrine deposits, consisting primarily of loose to medium dense sand with some silt and clay. This material was deposited in an ice- dammed lake in the Duwamish Valley,during recession of the latest continental glaciation;the Vashon Stade of the Fraser Glaciation. 2 Holocene alluvium from the Cedar River,consisting of loose sand and gravel with thin beds of silt, clay, and peat. 3 The Eocene Renton Formation,consisting of sandstone, mudstone, and shale and ' some coal beds. The sandstone is arkosic(25%or more feldspar)and irregularly cemented with calcium carbonate. Typically,it is poorly indurated and can be drilled with a hollow stem auger. The hill slope immediately south of I-405 is also mapped as the Renton Formation. 3.3 SUBSURTACE CONDITIONS Native soils encountered in the boreholes were in general conformance with the geologic , map. However,from 1 to 3 feet of fill was present,beneath the asphalt pavement, in each of the borings,overlying native soils. The soils encountered were as follows, in order from youngest to oldest: Fill: Gravel sub-base material was present beneath the parking lot pavement,to depths of approximately 2 to 3 feet. In BH-1,beyond the southern margin of the parking lot, silty sand fill was present to a depth of one foot. Buried Topsoil: A one-foot thickness of topsoil was present in BH-1,at a depth interval of 1 to 2 feet,and consisted of dark brown silty clay. Alluvium: Soft peat, organic silt,and loose to medium dense silty sand. deposited in a , fluvial environment,were encountered in borehole BH-2. The total thickness of peat and organic silt in BH-2 was approximately 15'/2 feet, extending from 8'/2 to 20 feet and 24 to 28 feet below the ground surface. Supplemental drilling was conducted along an alternative alignment to determine if it was possible to avoid the peat. However,the additional drilling encountered a 10 foot thickness of peat and organic silt at BH-5,nearly 6 feet of peat in BH- 6, and nearly 5 feet of peat in BH-7. The alluvium,as described above,extended to the full depths explored(26.5 to 31.5 feet)in these additional three boreholes. Both the peat and 1 2006-067 Rev Tinalldoc 4 HWA GEOSCIENCES INC. January 12, 2007 ••� HWA Project No. 2006-067-21 organic silt are highly compressible,which likely contributed to the settlement of the catch basin and storm pipe by borehole BH-2,and the segment of the north-south sanitary sewer line crossing this area. Boreholes BH-3 and BH-4 encountered silty sand alluvium to depths of 7 and 4'/2 feet, respectively. Recessional Glaciolacustrine: This deposit was encountered in boreholes BH-1 through BH-4,and was revealed to be a generally fining-upward sequence,typical of a glacial meltwater depositional environment in which the meltwater source is receding. It consisted of several feet of medium stiff clay, over stiff silt and medium dense silty sand. Sandstone(Renton Formation): Borehole 1311-1 encountered medium dense to very dense weathered sandstone,at a depth of 10%2 feet. The feldspar and rock grains crumbled under finger pressure,as well as during grain size analyses, indicating a high degree of chemical weathering. This does not occur with similar-appearing glacial advance outwash sands in the area. Boreholes BH-2 through BH-4 were terminated at greater depths than BH-1,without encountering the Renton Formation. 3.4 GROUND WATER CONDITIONS Ground water levels observed in the boreholes were recorded on the borehole logs. However, MW observations of water levels during drilling can be misleading. Actual ground water levels are often higher than those observed,because boreholes are typically open only for a short time,and the auger used to advance the borehole can smear the side of the hole inhibiting .� seepage. Moreover,the ground water elevations reported on the borehole logs are for the specific dates and locations indicated and,therefore, may not be indicative of other times and/or locations. Ground water level readings were taken in the open borings upon completion and in the piezometers on June 16 and 23,2006. Water level observations in the open borings and piezometers are summarized in Table 1. However,to gain an appreciation of seasonal ground water variations,measurements should be made during times of typical seasonal high ground water,in late winter and early spring. 2006-067 Rev Pinal2.doc 5 14WA GEOSCIENCES INC.

The methods are discussed in Appendix C,and conclusions are summarized in Section 4.5,Dewatering. 4.0 CONCLUSIONS AND RECOMMENDATIONS 4.1 GENERAL Based on the subsurface conditions encountered in our geotechnical investigation,the following will affect the design and construction of the proposed project: • The proposed storm sewer will traverse loose or soft alluvial soils below the ground water table. In general,the soils are capable of supporting the new sewer, considering that the culvert sections will likely weigh less than the soil it displaces. However,over- . 2006-067 Rev Final2.doc 6 HWA GROSCrFNCES INC. January 12,2007 HWA Project No. 2006-067-21 .w excavation of trench base through the peat area will be necessary to effect suitable subgrade support conditions and,depending upon the width and configuration of the IM trench excavation actually undertaken for the line by the contractor, it is possible that the weight of combined baekfill and culvert could increase stresses on the underlying compressible soils. Therefore,we recommend the use of a foamed concrete CDF as the culvert foundation,and lightweight fill such as bottom ash for trench baekfill up to 2 feet from the ground surface. Additionally, depending on trench characteristics, it may be desirable to backfill some of the culvert with the same material to reduce stresses to at .. least a neutral condition. • An existing 12-inch A.C. sewer pipeline is in close proximity to the proposed alignments, lying some 40 feet east of the existing 48-inch CMP and of the order of 20 feet east of the preferred replacement alignment,as indicated on Figure 2. This sewer line was camera surveyed by the City on October 23,2006, and the results indicate a sag in the line, extending from approximately its under-crossing of the existing 42-inch concrete storm line to a point about 160 feet to the south. This sag is considered to represent post- installation settlement,likely due to consolidation of underlying compressible soils. We understand that the City considers the settled sewer pipeline to be presently serviceable, but is presumably sensitive to additional settlement and vibration. "' • Ground water levels should be anticipated to range from approximately 3 to 7 feet above trench invert. Much of the dewatering requirements for this project are anticipated to be accomplished with sumps. The use of localized sumps would minimize potentially ' damaging settlements to adjacent utilities and pavements that can occur with dewatering wells in such soil conditions. • Shoring will be needed along most or all the storm sewer trench alignment, depending on soil type,ground water seepage conditions, and proximity to existing utilities. The following sections provide recommendations for foundation design, shoring and lateral earth pressures,dewatering,and construction considerations. MW 4.2 FOUNDATIONS ,,. 4.2.1 Seismic Considerations Buried culverts are typically not required to be designed to seismic design standards (AASHTO, 1996). Accorduigly, unless otherwise requested,seismic parameters have not been provided herein. Our assessment of the liquefaction potential of soil deposits at this site suggests that substantial portions of the silty sand(SP/SM)material encountered in the borings can liquefy under a moderate to severe earthquake event. Only the silt(ML) and clay(CL/CH), and 2006-067 Rev Finalldoo 7 HWA GEOSC[ENCES INC. r January 12,2007 HWA Project No. 2006-067-21 organic(0I-1/PT)layers are considered unlikely to liquefy during a design(i.e. 1 in 475 year) seismic event,because of either their very high fines content and/or inherent plasticity ' characteristics. We understand that the new culvert will have an invert level on the order of 6 to 8 feet in depth below existing site grades. Hence, allowing for over-excavation needed to construct the foundation system,the trench base will be I to 2 feet lower. Since this depth of over-excavation could result in penetration through the non-liquefiable clay layer and into the liquefiable silty sand, in the vicinity of BH-1,we recommend that the invert depth be established as high as practicable,particularly in the lower end of the system. Empirical relationships suggest that volumetric strains associated with soil liquefaction at this site may be on the order of 1 to 3 percent,dependent on variability of soil conditions. Conservatively assuming that soil confinement at depth will limit lateral straining, the , estimated vertical displacements associated with liquefaction range from 1 to S inches. However,the likely range of settlement would be of the order of I to 2 inches in our opinion. Lateral spreading of the soils near the outlet channel is probable during the design seismic event, inasmuch as the top of the liquefiable zone is near or within the base of the channel banks. This lateral spreading could cause culvert joints to pull apart along the Iower end of the pipeline. The cost of preventing liquefaction(i.e. installation of stone columns),or supporting the ' culvert on piles to eliminate settlement or lateral spreading effects would exceed the costs of repairs. Accordingly,these mitigation measures are considered unwarranted. 4.2.2 Subgrade Conditions For most of the alignment,it is anticipated that the trench base for the box culvert will expose medium stiff to stiff clay at foundation level,which will be suitable for support of the proposed culvert. Soft peat and organic silt were encountered at borehole BH-2, near the settled catch basin. The recent camera survey by the City of the 12-inch sanitary line, ' coupled with our review of site contours and additional borehole information, suggests that the soft peat and organic silt deposits exist as a relatively narrow buried channel infill. This subsurface channel feature appears to be of the order of 160 feet in width and appears to trend in a general northwest-southeast direction toward One Renton Place. Based on our borehole information and the camera survey,we believe that the northerly edge of the channelized soft , deposits lies just to the north of the 12-inch sanitary line under-crossing of the existing 42-inch concrete line. Our boring BH-2 and the existing storm manhole appear to lie in approximately the middle of this inferred channel of compressible materials. 2006-067 Rev Pinal2.doc 8 HWA GROSCIENCES INC. January 12, 2007 HWA Project No. 2006-067-21 To provide for a suitable foundation bearing layer, we recommend that the trench be over- excavated 2 feet where organic soils are present at or within 2 feet of bottom of culvert(see Figure 4, Trench Subgrade Preparation). To minimize disturbance to the foundation subgrade during excavation,the excavator should use a smooth-edged bucket rather than a toothed bucket. The over-excavated soil should be replaced with 2 feet of controlled density fill(CDF)comprising a foamed concrete,as discussed in Section 4.2.3. We anticipate approximately 160 feet of trench(for the preferred alignment shown on Figure 2) will require this treatment,based on the borehole logs,the observed asphaltic concrete pavement cracking and settlement in the vicinity,and the recent camera survey by the City. Another alternative alignment closer to the One Renton Place building was considered in order to reduce the length of alignment over peat. However, in view of the additional borehole(BH-5, BH-6, .. and BH-7)findings,it is evident that peat underlies the easternmost alternative alignment as well and may,in fact,represent a total lineal extent greater than that affecting the initially preferred alignment. Hence,we understand that the initially preferred alignment will be �- maintained for the proposed new system. In areas beyond the limits of the organic soils, it would be acceptable to employ 1 '/a-inch minus crushed rock as the foundation bearing layer, and the depth of over-excavation may be reduced to 1 foot for this support layer(see Figure 4). In transition zones between over- excavated sections within poorer subgrade areas, the base of the over-excavated areas should taper uniformly at no steeper than 5H:1 V(Horizontal:Vertical)to the areas where over- excavation is not required. Abrupt steps in the over-excavation intervals should be avoided. The crushed rock should conform to the requirements outlined in Section 9-03.9 (1)Ballast, of the 2006 WSDOT Standard Specifications. The replacement fill should extend to 3 feet on either side of the culvert. The crushed rock should be compacted in lifts of about 12 inches with a vibratory plate compactor, or by static rolling with a small drum compactor. Compaction should be discontinued if pumping of the pad and underlying subgrade becomes apparent. We prefer CDF as the bearing material throughout since its use prevents disturbance to the supporting subgrade soils beneath the new culvert and its foundation system. In this latter ,., regard,we anticipate that the foundation system will comprise precast concrete slab sections that may be supported on a thin(6 inches or less) granular leveling course,placed on the CDF, or directly on the structural fill. 4.2.3 Estimated Settlement We have analyzed the City's camera survey data,which indicates that the maximum settlement of the 12-inch sanitary sewer line has been of the order of 2 to 2.5 feet,assuming that it was initially installed on a linear uniform profile between the manhole intervals +• surveyed. This maximum sag occurs roughly in the same area as the adjacent storm manhole, which appears to have settled at least 1.78 feet, based on an assumed level pipe invert profile 2006-067 Rev Pinalldoc 9 HWA GEOSCIENCGS INC. r January 12, 2007 ' HWA Project No. 2006-067-21 between manhole and outfall. As indicated previously,the location of maximum settlement appears to be in the approximate center of what is inferred to be a subsurface or buried channel infilled with compressible organic silt and peat deposits. Boring BH-2 is in this area and indicates some 15.5 feet of compressible soils, which are overlain by a combined 8.5 feet of fill and alluvium of much lower compressibility. The fill thickness appears to be of the order of 3 feet at this location, and reduces to about 1-foot thickness at BH-1 to the south. Although we do not know the timing of construction of the sewer and the parking lot in this location,it seems apparent to us that the fill was placed for the parking lot development after the sewer line had been constructed. The added weight of 3 feet of granular fill would have induced loading of the compressible organic silt and peat and would have generated consolidation of these deposits,accompanied by settlements of the sewer line which is located at about 7 to 8 feet in depth in this location. Whereas the existing surface features of the parking lot do not immediately suggest this degree of surface settlement, available ground , profiles along the existing storm line and sanitary sewer tend to support this conclusion. To determine whether 3 feet of fill could generate this order of settlement,we undertook , settlement calculations based on the soil profile at BH-2 and assumed consolidation parameters for the various soil units,based on our experience. Our analyses indicate that from 18 to 23 inches(1.5 to 1.9 feet)would be generated by 3 feet of granular fill placed over ' the soil profile observed in BH-2,which we consider to be generally in good agreement with the settlement observations that have been made on both the existing sanitary and storm , sewer lines. Our recent consolidation testing of a sample of the peat from BH-5, which we consider to likely be representative of the peat deposit in this area,confirms the consolidation parameters initially assumed for this material. Recalculation of the settlement with the new , parameters provided an estimated amount of 17 inches. The additional laboratory testing has also confirmed that the deposit is normally consolidated under existing site conditions. In our opinion,this tends to support the assumption that the parking lot development occurred ' after installation of both sewer lines and consisted of filling the site area to provide for suitable grades. It also demonstrates that the existing organic silt and peat deposits are highly compressible and will undergo significant additional settlement if loaded to any significant degree. For static conditions, it is anticipated that the net loading contributed by the new culvert , section and backfill can be proportioned in such a manner as to approximately balance that removed in the form of excavated soil and fill materials that are present along the proposed alignment. Consequently, theoretical settlement for the culvert section should be zero. , However, the amount of loading that is experienced at and below the culvert invert level will depend to a significant degree on the contractor's trench excavation methods. If a broad, unbraced, sloped trench excavation is employed, it is possible that the combined weight of the culvert section and backfrll materials could,in fact, generate a net pressure increase on the soils supporting the proposed new culvert. We estimate that this net increase could ' 2006-067 Rev Finalldoc 10 HWA GFoSCIENCES INC. VW January 12, 2007 .. IOWA Project No. 2006-067-21 amount to as much as 300 psf at the base of the culvert bearing layer. Conversely,if the trench is braced and excavated with vertical walls to the limits necessary to place the bearing material and culvert,the backfill requirements will be substantially reduced and would provide for a small(estimated at less than 25 psf)unloading effect. Our estimate of settlement for these localized loading conditions indicates that the induced settlement could ow range from the order of 10 inches for the 300 psf loading level to zero for the Iatter case. In view of the uncertainties associated with trench excavation and backfilling methodologies aw that the contractor may employ,we recommend that it would be beneficial to consider use of light-weight materials for trQ;ich backfill,at least through the alignment section underlain by compressible organic silt and peat deposits. Moreover, subgrade disturbance during construction oftentimes results in soil recompression effects which manifest themselves in settlement of the newly installed pipe section. To prevent or mitigate this potential occurrence, it will be necessary to prevent subgrade disturbance during excavation, dewatering,pipe placement and backfilling to the extent practicable. To this end,use of CDF for foundation support material will limit subgrade disturbance to the maximum degree and be conducive to reduction of recompression settlement effects. With regard to the CDF material,we believe that it would be of further benefit to employ a foamed concrete product that can be mixed and installed with a substantially reduced unit- weight. Elastizell is such a product that we have experience with and can be produced on site in a wide range of unit weights ranging from about 30 to 110 pcf,with strengths ranging from the order of 150 to 1500 psi. We recommend use of an Elastizell,or equivalent foamed concrete,mix with unit weight of the order of 60 pcf,providing a strength in the range of 300 to 500 psi. Our research indicates that there is a local supplier of this material and costs are _ reported to be somewhat higher than conventional CDF,depending on volume of product required. Elastizell or foamed concrete could be placed as backfill around the pipe section as well,but is likely too costly for this purpose,and we suggest that bottom ash be considered as a light- weight alternative for backfill of the pipe zone and to within about 2 feet of finished grade. Our experience with this material indicates that it has a maximum compacted dry density of the order of 75 pcf, and for this project could be suitably compacted to about 95 pcf wet density. Again,we recommend that this treatment be considered for that section of culvert alignment crossing the compressible area to mitigate potential fixture settlements. The remainder of the culvert alignment should be amenable to conventional foundation and backfill treatment reeornmended herein, and settlements should be limited to tolerable levels �• if good construction practices are employed. Estimated settlement for seismic conditions is discussed in Section 4.2.1. These potential settlements will not be mitigated by the use of light-weight materials for pipe support and/or backfill, but will neither be exacerbated. 2006-067 Rev Final2.doc I I 14WA GEOSCIENCES NC. r i January 12, 2007 HWA Project No. 2006-067-21 4.3 LATERAL EARTH PRESSURES For determination of lateral earth pressure design parameters,we have assumed that the existing fill and native soils will be removed and replaced with a suitable granular backfill. hilt We have further assumed that the backfill adjoining/above the walls of the culvert will be placed to a horizontal condition at its surface and is compacted to the requirements provided for in Section 4.6. On the basis of an assumed wet unit weight of 125 pcf for the backfill and a friction angle of not less than 35 degrees,and seismic parameters appropriate for this site,we recommend the following equivalent fluid unit weights for a variety of potential design conditions. The earth pressure parameters presented in the first column are also based on fully-drained(dry) , conditions,or on conditions where the water levels within and exterior to the culvert are the same or balanced. That is,the culvert is not anticipated to be water tight and, if the water ' table rises, it is anticipated to infiltrate the pipe and maintain an equilibrium hydrostatic pressure condition on the culvert walls. More likely,water levels within the pipe will be somewhat higher than the adjoining water table, when storm runoff flows are being handled , by the culvert. In the extreme and most unlikely case that the pipe were to be dry and the backfill became flooded to the surface,buoyant conditions would apply and the second column of values provides the lateral earth pressures that would apply for design ' considerations. In our view,however,the pipe section should be considered a rigid element and we recommend that the static,at-rest,earth pressure value under balanced hydrostatic conditions be utilized for design of the culvert elements. Loading Condition Equivalent Fluid Unit Weight(yel) Dry or Balanced State Buoyant State , Active—Static(KA) 35 80 ' Active—Seismic(KAE) 40 85 At Rest—Static(Ko) 55 90 At Rest—Seismic (KoE) 80 100 , Passive- Static(KP) 460 295 Passive- Seismic(KPE) 435 280 ' It is also to be noted that the earth pressure parameters are unfactored or ultimate values. If passive earth pressure conditions need to be considered in respect to lateral restraint of the culvert section,an appropriate factor of safety(FS = 1.5) should be applied to the passive forces and we also recommend an allowable coefficient of sliding resistance equal to 0.45 ' 2006-067 Rev Final2.doe 12 HWA GEOScicNCFS INC. January 12,2007 .. HWA Project No. 2006-067-21 aw between foundation base slabs and underlying granular soils for determination of sliding resistance. i 4.4 EXCAVATION STABILITY AND SNORING 4.4.1 General Excavation for the storm sewer can be accomplished with conventional equipment such as backhoes and trackhoes. The excavation is anticipated to have a maximum depth on the order of 8 to 10 feet. Maintenance of safe working conditions,including temporary excavation stability,is the responsibility of the contractor. All temporary excavation in excess of 4 feet in depth must be sloped in accordance with Part N of WAC(Washington Administrative Code)296-155, or be shored. The near surface materials generally classify as Type C soil,for which WAC requires that unsupported excavation walls must be inclined no steeper than 1.5H:1 V,but flatter slopes may be necessary because of water seepage. With time and the occurrence of seepage and/or precipitation,the stability of temporary unsupported cut slopes may be significantly reduced. .� 4.4.2 Shoring We recommend the use of shoring in order to reduce impacts to adjacent utilities,minimize the volume of excavation spoils and backfill,and minimize the area of pavement to be restored. It should be recognized that trench boxes do not typically act as excavation slope shoring, but serve as protection for workers operating within the confines of the excavation. If trench boxes are used on this project, sloughing of excavation slopes may be anticipated resulting in potential disturbance to areas and facilities adjoining the open trenches where they are deployed. We understand that for the nearby 7th' Street storm sewer replacement, trench boxes were used with steel sheets installed just outside the boxes and pushed deeper into the soil. rSheet piles are not anticipated to be required,except perhaps in localized areas where it may be necessary to restrict the excavation to tight limits and prevent any potential for collapse of trench wails. In this condition, care will be essential to prevent potential damage to adjoining facilities from vibrations during pile driving. If required, we recommend that the design of temporary shoring should be based on a uniform lateral pressure distribution of 25H psf(where H is the depth of the excavation in feet). This pressure does not include any surcharges due to equipment or materials near the shoring and assumes that water pressures do not act above the base of the excavation. Dewatering may be necessary to achieve this ground water condition. II 2006-067 Rev Final2.doc 13 HWA GEOSCTENCES INC. January 12,2007 HWA Project No. 2006-067-21 4.5 DE-WATERING Design and implementation of temporary project dewatering systems is typically the responsibility of the contractor. Soils and ground water information that the contractor may use for design of his dewatering system needs are presented herein. However,within the scope of this investigation,we have made some preliminary assessments of ground water conditions at the site and potential dewatering requirements. We anticipate ground water will be present to approximately 3 to 7 feet above the trench ' invert elevation(including peat sections with 2 feet of over-excavation)along the planned trench section. We expect that much of the dewatering should be able to be accomplished with localized sumps. The use of localized short-term sumps for dewatering would minirnize , potentially damaging settlements to adjacent utilities and pavements that can occur with dewatering wells in such soil conditions. Well points may,however,be needed in the , vicinity of BH-4. For bidding purposes,we estimate that well points should be assumed for approximately one-fourth of the alignment. In the event that greater need for well point dewatering proves to be necessary,we recommend that a dewatering contingency allowance be included in the project contract. Dewatering voltunes will likely vary along the trench alignment,due to the variability of geologic conditions,and depending on ground water levels at the time of construction. Based ' on the available site infonnation and HWA's limited testing program, an estimated dewatering requirement of approximately 1 to IS gallons per minute(gpm)per 100 feet of ' trench is expected(see Table 3,Appendix A for projected pumping rates). Discharge flows are expected to be the highest along the north end of the alignment. Additionally,a wider trench(14 feet)for the twin 48-inch pipe option would require slightly higher dewatering , volumes. Soils in the vicinity of BH-4 are silty sands,and ground water may be under a slight confining condition. Soils in the vicinity if BH-3 and BH-2, in the central portion of the proposed alignment,consist primarily of fine-grained soils(peat,clay and silt)overlying a thin(less than five feet thick)layer of silty sand. Piezometers were not completed in these borings,but dewatering needs in this vicinity will likely be less than those in the vicinity of BH-4. The transition from silty soils to weathered sandstone occurs somewhere between BH- 2 and BH-1. One concern in the vicinity of the southern end of the proposed alignment will , be the recharge influence from the open channel which the stormwater system empties into. However,due to the low permeabilities of the weathered sandstone in the vicinity,there is a low likelihood that significant recharge will occur from the channel,and pumping rates beyond the highest estimated rates(Table 3,Appendix Q are not expected. The dewatering rates were calculated for water levels measured during June of 2006. , Seasonal variability in ground water elevations is expected and dewatering requirements during wet seasons will likely be higher. ' 2006-067 Rev Final2.doe 14 HWA GEOSCIENCES INC. January 12,2007 .� HWA Project No. 2006-067-21 Where excessive seepage infiltration is experienced, construction dewatering is important because it will be very difficult to maintain stable slopes,prepare subgrade, evaluate subsurface conditions, and construct structures in the wet. In addition, upward seepage into '! the excavation base can cause sand boils and/or heaving. This is likely to be of greater concern in the southern section of the line(i.e., south of 1311-2), where ground water is likely to be present in the silty sand and organic materials anticipated at or near proposed invert depths. In this section, we recommend that the proposed excavation be dewatered to maintain the ground water level at least 3 feet below the base of the excavation, and dewatering measures should be implemented before excavation to final subgrade level begins. Dewatering should continue until the culvert has been placed and backfrlled,and is capable of resisting hydrostatic forces. Disposal of water will be a consideration that will have to be suitably resolved with environmental and fisheries agencies having jurisdiction. The need for well points is dependent on the depth of the excavation, volume of ground water seepage,and potential presence of boiling or quick conditions in the excavation base. The latter condition will need to be evaluated at the time the excavation is undertaken,as it will depend on the shoring methods and dewatering measures implemented by the contractor. Construction dewatering requirements will also depend on the time of year,water level in the discharge channel,recent rainfall and other factors. For this reason,we recommend construction should be performed during the dry season. The contractor should be made aware that, if the ground water is lowered by more than about 7 to 10 feet below current elevations for significant periods, settlement of nearby facilities could occur. We recommend that settlement of nearby facilities such as the sanitary sewer be monitored using optical survey methods during the period of any dewatering. Piezometers ' installed as part of the geotechnical investigation should be left in place to monitor seasonal changes in ground water levels,and to monitor ground water levels during construction dewatering, in order to assure that dewatering is not excessive,and potential settlement of organic soils does not occur at the site. Additionally, it is recommended that ground water monitoring wells or piezometers be installed between the works and adjoining critical facilities to permit observation of ground water levels. Should potentially adverse drawdown and/or settlements become apparent,it may be necessary to suspend the dewatering operations until mitigation measures,such as re-injection wells are designed and implemented. 4.6 BACKI+ILL PLACEMENT AND COMPACTION Trench and culvert backfill should consist of Gravel Backfill f6r Walls, as described in Section 9-03.12(2)of the 2006 WSDOT Standard Specifications, and be compacted in lifts to MR 95 percent of Modified Proctor dry density(ASTM D:1557). W 2006-067 Rev PinalUoa 15 HWA GEOSCIENCES INC. Im January 12, 2007 ' HWA Project No. 2006-067-21 During placement of the initial lifts, the backfill material should not be bulldozed into the ' excavation or dropped directly on the structure. Furthermore, heavy vibratory equipment ' should not be permitted to operate directly over the structure until at least 2 feet of material is present above the crown of the culvert section, unless otherwise approved by the structural engineer. ' The procedure to achieve proper density of compacted fill depends on the size and type of compaction equipment,the number of passes,thickness of the layer being compacted, and , soil moisture-density properties. If access or load considerations restrict the use of heavy equipment, smaller equipment can be used,but the soil must be placed in thin enough lifts to achieve the required compaction. If granular material has been employed for foundation , support of the pipe, care must be exercised in the lower levels of the pipe backfill to prevent excessive compaction and potential disturbance to the foundation material and subgrade soils. 4.7 EROSION CONSIDERATIONS ' Erosion of exposed soils can be minimized by careful grading practices,the appropriate use , of silt fences and/or straw bails and use of surface cover materials,as appropriate. Surface runoff control during construction should be the responsibility of the contractor,and , should be treated prior to discharge to a permanent discharge system such as a storm sewer, so as to comply with State water quality standards. Water fiorn sumps will also require treatment prior to discharge to the storm sewer. Permanent control of surface water should ' be incorporated in the final grading design. Water should not be allowed to pond immediately adjacent to foundations or paved areas. Grading measures, slope protection, ditching, sumps, dewatering, and other measures should be employed as necessary to permit , proper completion of the work. 5.0 CONDITIONS AND LIMITATIONS , We have prepared this report for use by Gray&Osborne and the City of Renton for design of , a portion of this project.

APPENDIX A r FIELD INVESTIGATION r r r i r r r ar r r r r APPENDIX A FIELD INVESTIGATION The field exploration program was performed in two phases;the original scope of work and a supplemental scope that was requested based on findings of the initial phase. Four boreholes(designated BH-1 through BH-4)were drilled on June 2nd and 13"',2006, and three boreholes (designated 1314-5 through BI-1-7)were drilled on December 8, 2006. All drilling was conducted by Holocene Drilling,Inc. of Fife,Washington,under subcontract to HWA. The boreholes were advanced using a Mobile B-59,truck-mounted,drill rig employing hollow-stem auger. The borehole locations were determined approximately in the field by pacing and taping distances from existing site features,after completion of .� drilling,and are indicated on the site and exploration plan,Figure 2. An engineering geologist from HWA supervised and logged the explorations and recorded pertinent information including sample depths, stratigraphy,soil engineering characteristics,and ground water occurrence. The boreholes were drilled and sampled to depths between 21.5 feet and 36.5 feet. At select intervals within each borehole, Standard Penetration Test(SPT)sampling was performed using a 2-inch outside diameter split- spoon sampler and a 140-pound auto-hammer. During the SPT test,a sample is obtained by driving the sampler 18 inches into the soil with the hammer free-falling 30 inches. The number of blows required for each 6 inches of penetration is recorded. The Standard Penetration Resistance("N-value") of the soil is calculated as the number of blows required for the final 12 inches of penetration. This resistance,or N-value,provides an indication of relative density of granular soils and the relative consistency of cohesive soils. Relatively undisturbed samples of compressible soils(peat)were obtained from boreholes BH-5 and BH-6 by pushing 3-inch diameter, 30-inch long,steel Shelby tubes into the soil at selected depths. At the completion of boreholes BH-1 and BH-4,piezometers or monitoring wells, consisting of 2-inch diameter PVC pipe,were installed. The piezometers were finished with flush-mounted surface monuments. Well completion details are indicated on the individual borehole logs. Ground water levels in the piezometers were measured on June 16 and 23,2006. The other boreholes were abandoned with bentonite chips upon termination of drilling, and the pavement was patched with concrete. r Soil samples were classified in the field and representative portions placed in plastic bags. Two Shelby tube samples were sealed with plastic caps and duct tape. These soil samples were returned to our laboratory for further examination and testing. The sampled soils were classified in general accordance with the classification system described in. Appendix A on Figure A-1. A key to the borehole log symbols is also presented in Figure aw 2006-067 Rev rinalldoc A-I HWA GEOScFENCEs INC. i A-l. The borehole logs are presented as Figures A-2 through A-8,and should be referenced for specific subsurface details at the borehole locations. However,the stratigraphic contacts shown on the logs represent the inferred boundaries between soil types, and may be gradational in nature and much less distinct than represented. 2006-067 Rev Final2.doe A-2 HWA GEOSCIENCES INC.

Laboratory tests were conducted on selected soil samples to characterize relevant engineering properties of the on-site materials. The laboratory testing "' program was performed in general accordance with appropriate ASTM Standards,as outlined below. Liquid Limit,Plastic Limit,And Plasticity Index of Soils (Atterberg Limit): Selected samples were tested using method ASTM D 4318,multi-point method. The results are reported on the attached Liquid Limit,Plastic Limit, and Plasticity Index reports found in Figure B-1. Moisture Content: The moisture contents of selected soil samples were determined in general accordance with ASTM D 2216. The results are shown at the sampled intervals on the appropriate summary logs in Appendix A. Particle Size Analysis of Soil: Selected samples were tested to determine the particle size distribution of material in general accordance with ASTM D 422. The results are summarized on the attached Grain Size Distribution reports,Figures B-2 through B-5,which also provide information regarding the classification of the sample and the moisture content at the time of testing. Organic Content: Organic contents were measured on selected soil samples from borehole BH- �' 2 in general accordance with ASTM D 2974. The results are reported on the log for 13H-2 in Appendix A. One Dimensional Consolidation Properties of Soil:The consolidation properties of a relatively undisturbed Shelby tube sample from borehole 1311-5 were measured in general accordance with ASTM D 2435. Saturation was maintained by inundation of the sample throughout the test. The sample was subjected to increasing increments of total stress,the duration of which was selected to exceed the time required for completion of primary consolidation as defined in the Standard, Method B. Unloading of the sample was carried out incrementally. The test results,in terms of a i void ratio(e) versus log pressure(stress)plot,are presented in Figure B-6. i yr 2006-067 Rev rinalldoc B-1 HWA GEoSciENCEs INC. i z � m Q J ~ 0c (Y) U- � LL It 0X00 LL }_ ' ` W QOco ----77 ti E N N r N L Q _ Q f— F- 0 0 J Cl) f� O �' Cl) _ O CL N N N N N U N o � c u� M v -Ir O Q O U U _ —i w N C�7 M N l-L O ^ o y R J a 0 c U N O d J J z � o U ■ CO Q Q U U Cl) U >- U m CN4 C U c -i m U ■ � � � �° a o o C/) a o 3 `° Q � o L°i > N .L7 m O O � I.L 71 4)C _ _ N > m t L O in uy o 0 c cD v� of ai m tz- fL' N lJ t L6 o r- ti ❑ M � N O crJ M 0 CO 1 J U S S S S 2 Vj U m m m m m w () Q Q o o 0 - z (D in ° Od)X30NI k IIOIIS` -Icl � • ■ A o a U co �C a f'1 � 0 N m fTl 0 0 o ° LL J � o r` co 6� N c 1 � J I— r 'r r- W O co N 2 o Co o L, ❑ O 0 o - o W O CD CO O = O $ F- W CD 0- V Lo ui � O d f � 0 0 °- -- ----- -- ---- -- -- -- U?

Our aquifer testing program included rate-of-fall (falling head) and rate-of-rise(rising head)slug tests on piezometers BH-1 and BH-4. We used the Bouwer and Rice method to analyze the slug test results in piezometers that displayed suitable drawdown curves. The Bouwer and Rice method can be used for "slug tests on partially or completely penetrating wells in unconfined aquifers for a wide range of geometry conditions"(Bouwer and Rice, 1976). Pumping Test A short-tern pumping test was conducted at BH-4 using a two-inch diameter electrical submersible pump. Response to pumping at the pumping well,and recovery after pumping was stopped,were measured using data logging pressure transducers. We used the Theis and Jacob method to analyze the recovery test results (Driscoll, 1986). Data from some tests was not analyzed due to interference from the sand filter pack,or other interference. Table 2 summarizes the slug and pumping test results. HWA analyzed the results of the slug and pumping tests using the above listed methods with the Aquifer Test for Windows Version 2.55 software(Rohrich, 1996). The pumping test data, drawdown curves,and calculations are included at the end of Appendix C. r Table 2 Pumping Test Analysis Results Well Test Estimated Comments ID K(ft/min) BH-1 Falling head 4.16x10' BH-1 Rising head 4.67x10"5 BH-4 Failing head(two NA Very rapid response, possible tests) well filter pack influence BH-4 Rising head (test 1) 1.38x103 ..

Height of controlled potentiometric surface above base of aquifer(h) -This value was estimated based on measured ground water levels,and estimated trench invert depths with an added four r feet of drawdown. Radius of influence(R.)-Radius of influence was estimated based on Suchart's formula: R. =300(H—h),f with R„H and h in feet,and K in cm/sec. The above-listed principal dewatering parameters serve as the basis for estimating dewatering flows. Extreme variability(spatially and temporally)throughout the site of these dewatering ' parameters requires simplifying assumptions based on the available data in order to develop estimates of dewatering volumes. This method assumes flow to wells along the trench. Trench dewatering estimates are summarized in Table 3.

A. DESCRIPTION OF AUTHORIZED ACTIVITIES Outfall Structures and Maintenance. Activities related to: (i) Construction of outfall structures and associated intake structures where the effluent from the outfall is authorized, conditionally authorized,or specifically exempted,or are otherwise in compliance with regulations issued under the National Pollutant Discharge Elimination System Program(Section 402 of the CWA),and (ii) Maintenance excavation,including dredging,to remove accumulated sediments blocking or restricting �+ outfall and intake structures, accumulated sediments from small impoundments associated with outfall and intake structures, and accumulated sediments from canals associated with outfall and intake structures,provided the activity meets all of the following criteria: a. The permittee notifies the District Engineer in accordance with General Condition 13; b. The amount of excavated or dredged material must be the minimum necessary to restore the ' outfalls, intakes,small impoundments,and canals to original design capacities and design configurations(i.e.,depth and width); ' C. The excavated or dredged material is deposited and retained at an upland site,unless otherwise approved by the District Engineer under separate authorization;and ' d. Proper soil erosion and sediment control measures are used to minimize reentry of sediments into waters of the US. The construction of intake structures is not authorized by this NWP,unless they are directly associated with an authorized outfall structure. For maintenance excavation and dredging to remove accumulated sediments, the notification must include information regarding the original design capacities and configurations of the facility and the presence of special aquatic sites(e.g.,vegetated shallows)in the vicinity of the proposed work.(Sections 10 and 404) +r B. CORPS REGIONAL CONDITIONS FOR THIS NWP None r C. EPA, PUYALLUP TRIBE AND CHEHALIS TRIBE WQC CONDITIONS FOR THIS NWP EPA,Puyallup Tribe and Chehalis Tribe water quality certification(WQC)has been denied without prejudice. An individual WQC is required for all Section 404 activities. r D. STATE WQC CONDITIONS FOR THIS NWP State WQC has been partially denied without prejudice for this permit. 1. The NWP authorizes outfall construction only and does not authorize the discharge of effluent from the outfall. No effluent shall be discharged until the applicant has received a National Pollutant Elimination System permit,waiver, or other applicable approval from the appropriate Federal State or local authority. 2. An individual 401 Certification is required for projects or activities authorized under this NWP if the project/activity will likely result in any of the following adverse effects: a. The project or activity will likely cause or contribute to an exceedance of a State water quality standard(WAC 173-201A)or sediment quality standard(WAC 173-204). The requirement to obtain an individual 401 certification shall not apply to projects or activities that are carried out in accordance with the following permits,approvals,or management practices. These projects are presumed to comply with state water quality standards including state sediment • management standards: (1) Projects,activities or portions of projects or activities designed,constructed,and maintained in accordance with the stormwater standards and practices contained in the most current version of Ecology's Stormwater Manual or an Ecology approved equivalent. ■r (2) For WSDOT in-water or over-water construction and maintenance activities,an individual 401 certification is not required for those projects carried out in compliance r 2 with conditions 2 through 4 below and the Ecology approved Implementing Agreement regarding compliance with the state of Washington Surface Water Quality Standards. Compliance with this condition will be determined through receipt of a signed statement by the WSDOT project engineer or maintenance supervisor, guaranteeing that the project will meet the latest Ecology approved Water Quality Implementing Agreement for work In-Water. This statement shall be sent to the Corps of Engineers along with the JARPA application. b. For projects/activities not designed in accordance with either Ecology's stormwater manual or an Ecology approved equivalent,or for projects where there is credible site specific information which indicates that the permits,approvals, or management practices identified above will not be sufficient to meet state water quality standards,the applicant may provide documentation with the application that the project/activity will otherwise comply with state water quality standards. An individual 401 Certification is required for projects which are unable to provide documentation that the project/activity will otherwise comply with state water quality standards. c. Projects or activities that cause or contribute to a discharge to a waterbody on the state's list of impaired waterbodies[i.e.,the 303(d)list]and the discharge may result in further exceedances of a specific parameter the waterbody is listed for. The current list of 303(d)-listed waterbodies is available on Ecology's web site at .�. http://Www.ecy.wa.gov programs/wq/303d/1998/wrias/1998_water_Segs.pd.f or by contacting Ecology's Federal Permits staff. NOTE: An individual 401 Certification will not be required if the applicant provides documentation showing that ... the project or activity will either not result in a discharge containing the listed parameter or,if present,the parameter will not contribute to an increased impairment of the waterbody. ... d. Projects that do not incorporate structures and/or modifications beneficial for fish or wildlife habitat(e.g.,soil bioengineering,biotechnical design,rock barbs,etc.) .. NOTE:An individual 401 certification will not be required if the project/activity is designed and constructed in accordance to guidelines developed by the Washington State Department of Fish and Wildlife. E. STATE CZM CONSISTENCY DETERMINATION CONDITIONS FOR THIS NWP The Coastal Zone Management(CZM)Consistency Determination has been partially denied without prejudice for this NWP. An individual CZM Consistency Response must be obtained for projects requiring individual 401 Certification and located within counties in the coastal zone. F. CORPS NATIONAL GENERAL CONDITIONS FOR ALL NWPs 1. Navigation. No activity may cause more than a minimal adverse effect on navigation. 2. Proper Maintenance. Any structure or fill authorized shall be properly maintained,including maintenance to ensure public safety. 3. Soil Erosion and Sediment Controls. Appropriate soil erosion and sediment controls must be used and maintained in effective operating condition during construction,and all exposed soil and other fills,as well as any work below the ordinary high water mark or high tide line,must be permanently stabilized at the earliest practicable date. Permittees are encouraged to perform work within waters of the United States during periods of low-flow or no-flow. 3 4. Aquatic Life Movements. No activity may substantially disrupt the necessary life-cycle movements of those ' species of aquatic life indigenous to the waterbody,including those species that normally migrate through the area, unless the activity's primary purpose is to impound water. Culverts placed in streams must be installed to maintain low ' flow conditions. 5. Equipment. Heavy equipment working in wetlands must be placed on mats,or other measures must be taken to minimize soil disturbance. 6. Regional and Case-By-Case Conditions. The activity must comply with any regional conditions that may have been added by the Division Engineer(see 33 CFR 330.4(e))and with any case specific conditions added by the Corps or by the state or tribe in its Section 401 Water Quality Certification and Coastal Zone Management Act consistency determination. 7. Wild and Scenic Rivers. No activity may occur in a component of the National Wild and Scenic River ' System;or in a river officially designated by Congress as a"study river"for possible inclusion in the system,while the river is in an official study status;unless the appropriate Federal agency,with direct management responsibility for such river,has determined in writing that the proposed activity will not adversely affect the Wild and Scenic River designation,or study status. Information on Wild and Scenic Rivers may be obtained from the appropriate Federal land management agency in the area(e.g.,National Park Service,U.S.Forest Service,Bureau of Land Management,U.S. Fish and Wildlife Service). ' 8. Tribal Rights. No activity or its operation may impair reserved tribal rights,including,but not limited to, reserved water rights and treaty fishing and hunting rights. 9. Water Quality. ' (a) In certain states and tribal lands an individual 401 Water Quality Certification must be obtained or waived(See 33 CFR 330.4(c)). (b) For NWPs 12, 14, 17, 18,32,39,40,42,43,and 44,where the state or tribal 401 certification(either generically or individually)does not require or approve water quality management measures,the penmittee must provide water quality management measures that will ensure that the authorized work does not result in more than minimal degradation of water quality(or the Corps determines that compliance with state or local standards,where applicable,will ensure no more than minimal adverse effect on water quality). An important component of water quality management includes stormwater management that minimizes degradation of the downstream aquatic system, including water quality(refer to General Condition 21 for stormwater management requirements). Another important component of water quality management is the establishment and maintenance of vegetated buffers next to open waters,including streams(refer to General Condition 19 for vegetated buffer requirements for the NWPs). This condition is only applicable to projects that have the potential to affect water quality. While appropriate measures must be taken,in most cases it is not necessary to conduct detailed studies to identify such measures or to require. monitoring. 10. Coastal Zone Management. In certain states,an individual state coastal zone management consistency , concurrence must be obtained or waived(see 33 CFR 330.4(d)). 11. Endangered Species. , (a) No activity is authorized under any NWP which is likely to jeopardize the continued existence of a threatened or endangered species or a species proposed for such designation,as identified under the Federal ' Endangered Species Act(ESA),or which will destroy or adversely modify the critical habitat of such species. Non- federal permittees shall notify the District Engineer if any listed species or designated critical habitat might be affected or is in the vicinity of the project,or is located in the designated critical habitat and shall not begin work on the activity until notified by the District Engineer that the requirements of the ESA have been satisfied and that the activity is ' authorized. For activities that may affect Federally-listed endangered or threatened species or designated critical habitat,the notification must include the name(s)of the endangered or threatened species that may be affected by the rri 4 VO r proposed work or that utilize the designated critical habitat that may be affected by the proposed work. As a result of formal or informal consultation with the FWS or NMFS the District Engineer may add species-specific regional endangered species conditions to the NWPs. (b) Authorization of an activity by a NWP does not authorize the"take"of a threatened or endangered species as defined under the ESA. In the absence of separate authorization(e.g.,an ESA Section 10 Permit,a Biological Opinion with"incidental take"provisions,etc.)from the USFWS or the NMFS,both lethal and non-lethal "takes"of protected species are in violation of the ESA. Information on the location of threatened and endangered species and their critical habitat can be obtained directly from the offices of the USFWS and NMFS or their world wide web pages at http.//wwwfivs.govlr9endspplendspp.html and http://www.nmfs.noaa.govlprot res/overview/es.html respectively. 12. Historic Properties. No activity which may affect historic properties listed,or eligible for listing,in the National Register of Historic Places is authorized,until the District Engineer has complied with the provisions of 33 CFR part 325,Appendix C. The prospective permittee must notify the District Engineer if the authorized activity may affect any historic properties listed,determined to be eligible,or which the prospective pernittee has reason to believe may be eligible for listing on the National Register of Historic Places,and shall not begin the activity until notified by the District Engineer that the requirements of the National Historic Preservation Act have been satisfied and that the activity is authorized. Information on the location and existence of historic resources can be obtained from the State Historic Preservation Office and the National Register of Historic Places(see 33 CFR 330.4(g)). For activities that may affect historic properties listed in,or eligible for listing in,the National Register of Historic Places,the notification must state which historic property may be affected by the proposed work or include a vicinity map indicating the location of the historic property. 13. Notification. (a) Timing: Where required by the terms of the NWP,the prospective permittee must notify the District Engineer with a preconstruction notification(PCN)as early as possible. The District Engineer must determine if the r notification is complete within 30 days of the date of receipt and can request additional information necessary to make the PCN complete only once. However,if the prospective permittee does not provide all of the requested information, then the District Engineer will notify the prospective permittee that the notification is still incomplete and the PCN review process will not commence until all of the requested information has been received by the District Engineer. The prospective permittee shall not begin the activity: (1) Until notified in writing by the District Engineer that the activity may proceed under the NWP with any special conditions imposed by the District or Division Engineer;or (2) If notified in writing by the District or Division Engineer that an Individual Permit is required;or (3) Unless 45 days have passed from the District Engineer's receipt of the complete notification and the prospective permittee has not received written notice from the District or Division Engineer. Subsequently,the permittee's right to proceed under the NWP may be modified,suspended,or revoked only in accordance with the procedure set forth in 33 CFR 330.5(d)(2). (b) Contents of Notification: The notification must be in writing and include the following information: (1) Name,address and telephone numbers of the prospective permittee; (2) Location of the proposed project; (3) Brief description of the proposed project;the project's purpose;direct and indirect adverse environmental effects the project would cause;any other NWP(s),Regional General Permit(s),or Individual Permit(s) used or intended to be used to authorize any part of the proposed project or any related activity. Sketches should be provided when necessary to show that the activity complies with the terms of the NWP(Sketches usually clarify the project and when provided result in a quicker decision.); 5 2 (4) For NWPs 7, 12, 14, 18,21,34,38,39,40,41,4 ,and 43,the PCN must also include a delineation of affected special aquatic sites,including wetlands,vegetated shallows(e.g.,submerged aquatic vegetation,seagrass ' beds),and riffle and pool complexes(see paragraph 13(o); (5) For NWP 7(Outfall Structures and Maintenance),the PCN must include information regarding the original design capacities and configurations of those areas of the facility where maintenance dredging or excavation is proposed; (6) For NWP 14(Linear Transportation Projects),the PCN must include a compensatory mitigation proposal to offset permanent losses of waters of the US and a statement describing how temporary losses of waters of the US will be minimized to the maximum extent practicable; (7) For NWP 21 (Surface Coal Mining Activities),the PCN must include an Office of Surface Mining (OSM)or state-approved mitigation plan,if applicable. To be authorized by this NWP,the District Engineer must determine that the activity complies with the terms and conditions of the NWP and that the adverse environmental effects are minimal both individually and cumulatively and must notify the project sponsor of this determination in writing; +rr (8) For NWP 27(Stream and Wetland Restoration Activities),the PCN must include documentation of the prior condition of the site that will be reverted by the permittee; (9) For NWP 29(Single-Family Housing),the PCN must also include: (i) Any past use of this NWP by the Individual Permittee and/or the permittee's spouse; (ii) A statement that the single-family housing activity is for a personal residence of the permittee; (iii) A description of the,entire parcel,including its size,and a delineation of wetlands. For the ' purpose of this NWP,parcels of land measuring 1/4-acre or less will not require a formal on-site delineation. However, the applicant shall provide an indication of where the wetlands are and the amount of wetlands that exists on the property. For parcels greater than 1/4-acre in size,formal wetland delineation must be prepared in accordance with the current method required by the Corps.(See paragraph 13(f)); (iv) A written description of all land(including,if available,legal descriptions)owned by the prospective permittee and/or the prospective permittee's spouse,within a one mile radius of the parcel,in any form of ownership(including any land owned as a partner,corporation,joint tenant,co-tenant,or as a tenant-by-the-entirety) and any land on which a purchase and sale agreement or other contract for sale or purchase has been executed; (10) For NWP 31 (Maintenance of Existing Flood Control Facilities),the prospective permittee must either notify the District Engineer with a PCN prior to each maintenance activity or submit a five year(or less) maintenance plan. In addition,the PCN must include all of the following: (i) Sufficient baseline information identifying the approved channel depths and configurations and existing facilities. Minor deviations are authorized,provided the approved flood control protection or drainage is not increased; (ii) A delineation of any affected special aquatic sites,including wetlands;and, (iii) Location of the dredged material disposal site; , (11) For NWP 33(Temporary Construction,Access,and Dewatering),the PCN must also include a restoration plan of reasonable measures to avoid and minimize adverse effects to aquatic resources; (12) For NWPs 39,43 and 44,the PCN must also include a written statement to the District Engineer explaining how avoidance and minimization for losses of waters of the US were achieved on the project site; 6 ' r a' (13) For NWP 39 and NWP 42,the PCN must include a compensatory mitigation proposal to offset losses of waters of the US or justification explaining why compensatory mitigation should not be required. For discharges that cause the loss of greater than 300 linear feet of an intermittent stream bed,to be authorized,the District Engineer must determine that the activity complies with the other terms and conditions of the NWP,determine adverse environmental effects are minimal both individually and cumulatively,and waive the limitation on stream impacts in writing before the permittee may proceed; (14) For NWP 40(Agricultural Activities),the PCN must include a compensatory mitigation proposal to offset losses of waters of the US. This NWP does not authorize the relocation of greater than 300 linear-feet of existing serviceable drainage ditches constructed in non-tidal streams unless,for drainage ditches constructed in intermittent non-tidal streams,the District Engineer waives this criterion in writing,and the District Engineer has determined that the project complies with all terms and conditions of this NWP,and that any adverse impacts of the project on the aquatic environment are minimal,both individually and cumulatively; (15) For NWP 43(Stormwater Management Facilities),the PCN must include,for the construction of new stormwater management facilities,a maintenance plan(in accordance with state and local requirements,if applicable)and a compensatory mitigation proposal to offset losses of waters of the US. For discharges that cause the r loss of greater than 300 linear feet of an intermittent stream bed,to be authorized,the District Engineer must determine that the activity complies with the other terms and conditions of the NWP,determine adverse environmental effects are minimal both individually and cumulatively,and waive the limitation on stream impacts in writing before the permittee may proceed; (16) For NWP 44(Mining Activities),the PCN must include a description of all waters of the US adversely affected by the project,a description of measures taken to minimize adverse effects to waters of the US,a description of measures taken to comply with the criteria of the NWP,and a reclamation plan(for all aggregate mining activities in isolated waters and non-tidal wetlands adjacent to headwaters and any hard rock/mineral mining activities); (17) For activities that may adversely affect Federally-listed endangered or threatened species,the PCN must include the name(s)of those endangered or threatened species that may be affected by the proposed work or utilize the designated critical habitat that may be affected by the proposed work;and (18) For activities that may affect historic properties listed in,or eligible for listing in,the National Register of Historic Places,the PCN must state which historic property may be affected by the proposed work or include a vicinity map indicating the location of the historic property. L (c) Form of Notification: The standard Individual Permit application form(Form ENG 4345)may be used as the notification but must clearly indicate that it is a PCN and must include all of the information required in(b)(1)- (18)of General Condition 13. A letter containing the requisite information may also be used. (d) District Engineer's Decision: In reviewing the PCN for the proposed activity,the District Engineer will determine whether the activity authorized by the NWP will result in more than minimal individual or cumulative adverse environmental effects or may be contrary to the public interest. The prospective permittee may submit a proposed mitigation plan with the PCN to expedite the process. The District Engineer will consider any proposed compensatory mitigation the applicant has included in the proposal in determining whether the net adverse environmental effects to the aquatic environment of the proposed work are minimal. If the District Engineer r determines that the activity complies with the terms and conditions of the NWP and that the adverse effects on the aquatic environment are minimal,after considering mitigation,the District Engineer will notify the permittee and include any conditions the District Engineer deems necessary. The District Engineer must approve any compensatory mitigation proposal before the permittee commences work. If the prospective permittee is required to submit a compensatory mitigation proposal with the PCN,the proposal may be either conceptual or detailed. If the prospective permittee elects to submit a compensatory mitigation plan with the PCN,the District Engineer will expeditiously review the proposed compensatory mitigation plan. The District Engineer must review the plan within 45 days of r. receiving a complete PCN and determine whether the conceptual or specific proposed mitigation would ensure no more than minimal adverse effects on the aquatic environment. If the net adverse effects of the project on the aquatic environment(after consideration of the compensatory mitigation proposal)are determined by the District Engineer to be minimal,the District Engineer will provide a timely written response to the applicant. The response will state that 7 r. r the project can proceed under the terms and conditions of the NWP. If the District Engineer determines that the adverse effects of the proposed work are more than minimal,then the District Engineer will notify the applicant either: (1)That the project does not qualify for authorization under the NWP and instruct the applicant on the procedures to seek authorization under an Individual Permit;(2)that the project is authorized under the NWP subject to the applicant's submission of a mitigation proposal that would reduce the adverse effects on the aquatic environment to the minimal level;or(3)that the project is authorized under the NWP with specific modifications or conditions. Where the District Engineer determines that mitigation is required to ensure no more than minimal adverse effects occur to the aquatic environment,the activity will be authorized within the 45-day PCN period. The authorization will include the necessary conceptual or specific mitigation or a requirement that the applicant submit a mitigation proposal that would �3' eP P q reduce the adverse effects on the aquatic environment to the minimal level. When conceptual mitigation is included,or a mitigation plan is required under item(2)above,no work in waters of the US will occur until the District Engineer has approved a specific mitigation plan. (e) Agency Coordination: The District Engineer will consider any comments from Federal and state agencies concerning the proposed activity's compliance with the terns and conditions of the NWPs and the need for mitigation to reduce the project's adverse environmental effects to a minimal level. For activities requiring notification to the District Engineer that result in the loss of greater than 1/2-acre of waters of the US,the District Engineer will provide immediately(e.g.,via facsimile transmission,overnight mail,or other expeditious manner)a copy to the appropriate Federal or state offices(USFWS,state natural resource or water quality agency,EPA,State Historic Preservation Officer(SHPO),and,if appropriate,the NMFS). With the exception of NWP 37,these agencies will then have 10 calendar days from the date the material is transmitted to telephone or fax the District Engineer notice that they intend to provide substantive,site-specific comments. If so contacted by an agency,the District Engineer will wait an additional 15 calendar days before making a decision on the notification. The District Engineer will fully consider agency comments received within the specified time frame,but will provide no response to the resource agency,except as provided below. The District Engineer will indicate in the administrative record associated with each notification that the resource agencies'concerns were considered. As required by section 305(b)(4)(B)of the Magnuson-Stevens Fishery Conservation and Management Act,the District Engineer will provide a response to NMFS within 30 days of receipt of any Essential Fish Habitat conservation recommendations. Applicants are encouraged to provide the Corps multiple copies of notifications to expedite agency notification. (f) Wetland Delineations: Wetland delineations must be prepared in accordance with the current method required by the Corps(For NWP 29 see paragraph(b)(9)(iii)for parcels less than(1/4-acre in size). The permittee may ask the Corps to delineate the special aquatic site. There may be some delay if the Corps does the delineation. Furthermore,the 45-day period will not start until the wetland delineation has been completed and submitted to the Corps,where appropriate. 14. Compliance Certification. Every permittee who has received NWP verification from the Corps will submit a signed certification regarding the completed work and any required mitigation. The certification will be forwarded by the Corps with the authorization letter and will include: (a) A statement that the authorized work was done in accordance with the Corps authorization,including any general or specific conditions; (b) A statement that any required mitigation was completed in accordance with the permit conditions;and (c) The signature of the permittee certifying the completion of the work and mitigation. 15. Use of Multiple Nationwide Permits. The use of more than one NWP for a single and complete project is r prohibited,except when the acreage loss of waters of the US authorized by the NWPs does not exceed the acreage limit of the NWP with the highest specified acreage limit(e.g.if a road crossing over tidal waters is constructed under NWP 14,with associated bank stabilization authorized by NWP 13,the maximum acreage loss of waters of the US for the total project cannot exceed 1/3-acre). i 16. Water Supply Intakes. No activity,including structures and work in navigable waters of the US or discharges of dredged or fill material,may occur in the proximity of a public water supply intake except where the ' activity is for repair of the public water supply intake structures or adjacent bank stabilization. 8 r 17. Shellfish Beds. No activity,including structures and work in navigable waters of the US or discharges of dredged or fill material,may occur in areas of concentrated shellfish populations,unless the activity is directly related to a shellfish harvesting activity authorized by NWP 4. rn. 18. Suitable Material. No activity,including structures and work in navigable waters of the US or discharges of dredged or fill material,may consist of unsuitable material(e.g.,trash,debris,car bodies,asphalt,etc.)and material used for construction or discharged must be free from toxic pollutants in toxic amounts(see section 307 of the CWA). 19. Mitigation. The District Engineer will consider the factors discussed below when determining the acceptability of appropriate and practicable mitigation necessary to offset adverse effects on the aquatic environment that are more than minimal. (a) The project must be designed and constructed to avoid and minimize adverse effects to waters of the US to the maximum extent practicable at the project site(i.e.,on site). (b) Mitigation in all its forms(avoiding,minimizing,rectifying,reducing or compensating)will be required to the extent necessary to ensure that the adverse effects to the aquatic environment are minimal. (c) Compensatory mitigation at a minimum one-for-one ratio will be required for all wetland impacts requiring a PCN,unless the District Engineer determines in writing that some other form of mitigation would be more environmentally appropriate and provides a project-specific waiver of this requirement. Consistent with National policy,the District Engineer will establish a preference for restoration of wetlands as compensatory mitigation,with preservation used only in exceptional circumstances. (d) Compensatory mitigation(i.e.,replacement or substitution of aquatic resources for those impacted)will not be used to increase the acreage losses allowed by the acreage limits of some of the NWPs. For example, 1/4-acre of wetlands cannot be created to change a 3/4-acre loss of wetlands to a 1/2-acre loss associated with NWP 39 verification. However, 1/2-acre of created wetlands can be used to reduce the impacts of a 1/2-acre loss of wetlands to the minimum impact level in order to meet the minimal impact requirement associated with NWPs. (e) To be practicable,the mitigation must be available and capable of being done considering costs,existing technology,and logistics in light of the overall project purposes. Examples of mitigation that may be appropriate and practicable include,but are not limited to: reducing the size of the project; establishing and maintaining wetland or upland vegetated buffers to protect open waters such as streams;and replacing losses of aquatic resource functions and values by creating,restoring,enhancing,or preserving similar functions and values,preferably in the same watershed. (f) Compensatory mitigation plans for projects in or near streams or other open waters will normally include r a requirement for the establishment,maintenance,and legal protection(e.g.,easements,deed restrictions)of vegetated buffers to open waters. In many cases,vegetated buffers will be the only compensatory mitigation required. Vegetated buffers should consist of native species. The width of the vegetated buffers required will address documented water quality or aquatic habitat loss concerns. Normally,the vegetated buffer will be 25 to 50 feet wide on each side of the stream,but the District Engineers may require slightly wider vegetated buffers to address documented water quality or habitat loss concerns. Where both wetlands and open waters exist on the project site,the Corps will determine the appropriate compensatory mitigation(e.g.,stream buffers or wetlands compensation)based on what is best for the aquatic environment on a watershed basis. In cases where vegetated buffers are determined to be the most appropriate form of compensatory mitigation,the District Engineer may waive or reduce the requirement to provide wetland compensatory mitigation for wetland impacts. (g) Compensatory mitigation proposals submitted with the"notification"may be either conceptual or aw detailed. If conceptual plans are approved under the verification,then the Corps will condition the verification to require detailed plans be submitted and approved by the Corps prior to construction of the authorized activity in waters of the US. (h) Permittees may propose the use of mitigation banks,in-lieu fee arrangements or separate activity-specific compensatory mitigation. In all cases that require compensatory mitigation,the mitigation provisions will specify the party responsible for accomplishing and/or complying with the mitigation plan. 9 20. Spawning Areas. Activities,including structures and work in navigable waters of the US or discharges of dredged or fill material,in spawning areas during spawning seasons must be avoided to the maximum extent practicable. Activities that result in the physical destruction(e.g.,excavate,fill,or smother downstream by substantial turbidity)of an important spawning area are not authorized. 21. Management of Water Flows. To the maximum extent practicable,the activity must be designed to maintain preconstruction downstream flow conditions(e.g.,location,capacity,and flow rates). Furthermore,the activity must not permanently restrict or impede the passage of normal or expected high flows(unless the primary purpose of the fill is to impound waters)and the structure or discharge of dredged or fill material must withstand expected high flows. The activity must,to the maximum extent practicable,provide for retaining excess flows from the site,provide for maintaining surface flow rates from the site similar to preconstruction conditions,and provide for not increasing water flows from the project site,relocating water,or redirecting water flow beyond preconstruction conditions. Stream channelizing will be reduced to the minimal amount necessary,and the activity must,to the maximum extent practicable,reduce adverse effects such as flooding or erosion downstream and upstream of the project site,unless the activity is part of a larger system designed to manage water flows. In most cases,it will not be a requirement to conduct detailed studies and monitoring of water flow. This condition is only applicable to projects that have the potential to affect waterflows. While appropriate measures must be taken,it is not necessary to conduct detailed studies to identify such measures or require monitoring to ensure their effectiveness. Normally,the Corps will defer to state and local authorities regarding management of water flow. 22. Adverse Effects From Impoundments. If the activity creates an impoundment of water,adverse effects to the aquatic system due to the acceleration of the passage of water,and/or the restricting its flow shall be minimized to the maximum extent practicable. This includes structures and work in navigable waters of the US,or discharges of dredged or fill material. 23. Waterfowl Breeding Areas. Activities,including structures and work in navigable waters of the US or discharges of dredged or fill material,into breeding areas for migratory waterfowl must be avoided to the maximum extent practicable. 24. Removal of Temporary Fills. Any temporary fills must be removed in their entirety and the affected areas returned to their preexisting elevation. 25. Designated Critical Resource Waters. Critical resource waters include,NOAA-designated marine sanctuaries,National Estuarine Research Reserves,National Wild and Scenic Rivers,critical habitat for Federally listed threatened and endangered species,coral reefs,state natural heritage sites,and outstanding national resource waters or other waters officially designated by a state as having particular environmental or ecological significance and identified by the District Engineer after notice and opportunity for public comment. The District Engineer may also designate additional critical resource waters after notice and opportunity for comment. (a) Except as noted below,discharges of dredged or fill material into waters of the US are not authorized by NWPs 7, 12, 14, 16, 17,21,29,31,35,39,40,42,43,and 44 for any activity within,or directly affecting,critical resource waters,including wetlands adjacent to such waters. Discharges of dredged or fill materials into waters of the US may be authorized by the above NWPs in National Wild and Scenic Rivers if the activity complies with General r Condition 7. Further,such discharges may be authorized in designated critical habitat for Federally listed threatened or endangered species if the activity complies with General Condition 11 and the USFWS or the NMFS has concurred in a determination of compliance with this condition. qr (b) For NWPs 3,85 10, 13, 15, 18, 19,22,23,25,27,28,30,33,34,36,37,and 38,notification is required in accordance with General Condition 13,for any activity proposed in the designated critical resource waters including wetlands adjacent to those waters. The District Engineer may authorize activities under these NWPs only after it is determined that the impacts to the critical resource waters will be no more than minimal. 26. Fills Within 100-Year Floodplains. For purposes of this General Condition, 100-year floodplains will be identified through the existing Federal Emergency Management Agency's(FEMA)Flood Insurance Rate Maps or _ FEMA-approved local floodplain maps. 10 ' (a) Discharges in Floodplain;Below Headwaters. Discharges of dredged or fill material into waters of the US within the mapped 100-year floodplain,below headwaters(i.e.,5 cfs),resulting in permanent above-grade fills,are not authorized by NWPs 39,40,42,43,and 44. (b) Discharges in Floodway;Above Headwaters. Discharges of dredged or fill material into waters of the US within the FEMA or locally mapped floodway,resulting in permanent above-grade fills,are not authorized by NWPs 39,40,42,and 44. (c) The permittee must comply with any applicable FEMA-approved state or local floodplain management requirements. 27. Construction Period. For activities that have not been verified by the Corps and the project was commenced or under contract to commence by the expiration date of the NWP(or modification or revocation date),the work must be completed within 12-months after such date(including any modification that affects the project). For activities that have been verified and the project was commenced or under contract to commence within the verification period,the work must be completed by the date determined by the Corps. For projects that have been verified by the Corps,an extension of a Corps approved completion date maybe requested. This request must be submitted at least one month before the previously approved completion date. G. CORPS REGIONAL GENERAL CONDITIONS FOR ALL NWPS 1. Mature Forested and Bog and Bog-like Wetlands.

STATE CZM CONSISTENCY DETERMINATION CONDITIONS FOR THIS NWP I The Coastal Zone Management(CZM)Consistency Determination has been partially denied without prejudice for this NWP. An individual CZM Consistency Response must be obtained for projects requiring individual 401 Certification and located within counties in the coastal zone. F. CORPS NATIONAL GENERAL CONDITIONS FOR ALL NWPS r 1. Navigation. No activity may cause more than a minimal adverse effect on navigation. 2. Proper Maintenance. Any structure or fill authorized shall be properly maintained,including maintenance to , ensure public safety. 3. Soil Erosion and Sediment Controls. Appropriate soil erosion and sediment controls must be used and maintained in effective operating condition during construction,and all exposed soil and other fills,as well as any work below the ordinary high water mark or high tide line,must be permanently stabilized at the earliest practicable date. Permittees are encouraged to perform work within waters of the United States during periods of low-flow or no-flow. 4. Aquatic Life Movements. No activity may substantially disrupt the necessary life-cycle movements of those species of aquatic life indigenous to the waterbody,including those species that normally migrate through the area, unless the activity's primary purpose is to impound water. Culverts placed in streams must be installed to maintain low flow conditions. 5. Equipment. Heavy equipment working in wetlands must be placed on mats,or other measures must be taken to minimize soil disturbance. 6. Regional and Case-By-Case Conditions. The activity must comply with any regional conditions that may have been added by the Division Engineer(see 33 CFR 330.4(e))and with any case specific conditions added by the Corps or by the state or tribe in its Section 401 Water Quality Certification and Coastal Zone Management Act consistency determination. 7. Wild and Scenic Rivers. No activity may occur in a component of the National Wild and Scenic River W System;or in a river officially designated by Congress as a"study river"for possible inclusion in the system,while the river is in an official study status;unless the appropriate Federal agency,with direct management responsibility for such river,has determined in writing that the proposed activity will not adversely affect the Wild and Scenic River designation,or study status. Information on Wild and Scenic Rivers may be obtained from the appropriate Federal land r management agency in the area(e.g.,National Park Service,U.S.Forest Service,Bureau of Land Management,U.S. Fish and Wildlife Service). 8. Tribal Rights. No activity or its operation may impair reserved tribal rights,including,but not limited to, .r reserved water rights and treaty fishing and hunting rights. 9. Water Quality. �r (a) In certain states and tribal lands an individual 401 Water Quality Certification must be obtained or waived(See 33 CFR 330.4(c)). (b) For NWPs 12, 14, 17, 18,32,39,40,42,43,and 44,where the state or tribal 401 certification(either generically or individually)does not require or approve water quality management measures,the permittee must provide water quality management measures that will ensure that the authorized work does not result in more than minimal degradation of water quality(or the Corps determines that compliance with state or local standards,where applicable,will ensure no more than minimal adverse effect on water quality). An important component of water quality management includes stormwater management that minimizes degradation of the downstream aquatic system, including water quality(refer to General Condition 21 for stormwater management requirements). Another important 4 +� component of water quality management is the establishment and maintenance of vegetated buffers next to open waters,including streams(refer to General Condition 19 for vegetated buffer requirements for the NWPs). This condition is only applicable to projects that have the potential to affect water quality. While appropriate measures must be taken,in most cases it is not necessary to conduct detailed studies to identify such measures or to require monitoring. 10. Coastal Zone Management. In certain states,an individual state coastal zone management consistency concurrence must be obtained or waived(see 33 CFR 330.4(d)). 11. Endangered Species. it (a) No activity is authorized under any NWP which is likely to jeopardize the continued existence of a threatened or endangered species or a species proposed for such designation,as identified under the Federal Endangered Species Act(ESA),or which will destroy or adversely modify the critical habitat of such species. Non- federal permittees shall notify the District Engineer if any listed species or designated critical habitat might be affected or is in the vicinity of the project,or is located in the designated critical habitat and shall not begin work on the activity until notified by the District Engineer that the requirements of the ESA have been satisfied and that the activity is authorized. For activities that may affect Federally-listed endangered or threatened species or designated critical habitat,the notification must include the name(s)of the endangered or threatened species that may be affected by the proposed work or that utilize the designated critical habitat that may be affected by the proposed work. As a result of formal or informal consultation with the FWS or NMFS the District Engineer may add species-specific regional endangered species conditions to the NWPs. (b) Authorization of an activity by a NWP does not authorize the"take"of a threatened or endangered species as defined under the ESA. In the absence of separate authorization(e.g.,an ESA Section 10 Permit,a Biological Opinion with"incidental take"provisions,etc.)from the USFWS or the NMFS,both lethal and non-lethal "takes"of protected species are in violation of the ESA. Information on the location of threatened and endangered species and their critical habitat can be obtained directly from the offices of the USFWS and NMFS or their world wide web pages at http://www.fws.govlr9endspplendspp.html and http://www.nmfs.noaa.govlprot res/overviewles.html respectively. 12. Historic Properties. No activity which may affect historic properties listed,or eligible for listing,in the National Register of Historic Places is authorized,until the District Engineer has complied with the provisions of 33 CFR part 325,Appendix C. The prospective permittee must notify the District Engineer if the authorized activity may affect any historic properties listed,determined to be eligible,or which the prospective permittee has reason to believe may be eligible for listing on the National Register of Historic Places,and shall not begin the activity until notified by the District Engineer that the requirements of the National Historic Preservation Act have been satisfied and that the activity is authorized. Information on the location and existence of historic resources can be obtained from the State Historic Preservation Office and the National Register of Historic Places(see 33 CFR 330.4(g)). For activities that may affect historic properties listed in,or eligible for listing in,the National Register of Historic Places,the notification must state which historic property may be affected by the proposed work or include a vicinity map indicating the location of the historic property. 13. Notification. .. (a) Timing: Where required by the terms of the NWP,the prospective permittee must notify the District Engineer with a preconstruction notification(PCN)as early as possible. The District Engineer must determine if the notification is complete within 30 days of the date of receipt and can request additional information necessary to make the PCN complete only once. However,if the prospective permittee does not provide all of the requested information, • then the District Engineer will notify the prospective permittee that the notification is still incomplete and the PCN review process will not commence until all of the requested information has been received by the District Engineer. The prospective permittee shall not begin the activity: (1) Until notified in writing by the District Engineer that the activity may proceed under the NWP with any special conditions imposed by the District or Division Engineer;or 5 aw (2) If notified in writing by the District or Division Engineer that an Individual Permit is required;or (3) Unless 45 days have passed from the District Engineer's receipt of the complete notification and the prospective permittee has not received written notice from the District or Division Engineer. Subsequently,the permittee's right to proceed under the NWP may be modified,suspended,or revoked only in accordance with the procedure set forth in 33 CFR 330.5(d)(2).

For the purpose of this NWP,parcels of land measuring 1/4-acre or less will not require a formal on-site delineation. However, the applicant shall provide an indication of where the wetlands are and the amount of wetlands that exists on the r property. For parcels greater than 1/4-acre in size,formal wetland delineation must be prepared in accordance with the current method required by the Corps.(See paragraph 13(f)); (iv) A written description of all land(including,if available,legal descriptions)owned by the prospective permittee and/or the prospective permittee's spouse,within a one mile radius of the parcel,in any form of ownership(including any land owned as a partner,corporation,joint tenant,co-tenant,or as a tenant-by-the-entirety) and any land on which a purchase and sale agreement or other contract for sale or purchase has been executed; 6 (10) For NWP 31 (Maintenance of Existing Flood Control Facilities),the prospective permittee must either notify the District Engineer with a PCN prior to each maintenance activity or submit a five year(or less) maintenance plan. In addition,the PCN must include all of the following: (i) Sufficient baseline information identifying the approved channel depths and configurations and existing facilities. Minor deviations are authorized,provided the approved flood control protection or drainage is not increased; (ii) A delineation of any affected special aquatic sites,including wetlands;and, (iii) Location of the dredged material disposal site; (11) For NWP 33(Temporary Construction,Access,and Dewatering),the PCN must also include a restoration plan of reasonable measures to avoid and minimize adverse effects to aquatic resources; (12) For NWPs 39,43 and 44,the PCN must also include a written statement to the District Engineer explaining how avoidance and minimization for losses of waters of the US were achieved on the project site; (13) For NWP 39 and NWP 42,the PCN must include a compensatory mitigation proposal to offset losses of waters of the US or justification explaining why compensatory mitigation should not be required. For discharges that cause the loss of greater than 300 linear feet of an intermittent stream bed,to be authorized,the District Engineer must determine that the activity complies with the other terms and conditions of the NWP,determine adverse environmental effects are minimal both individually and cumulatively,and waive the limitation on stream impacts in writing before the permittee may proceed; (14) For NWP 40(Agricultural Activities),the PCN must include a compensatory mitigation proposal to offset losses of waters of the US. This NWP does not authorize the relocation of greater than 300 linear-feet of existing serviceable drainage ditches constructed in non-tidal streams unless,for drainage ditches constructed in intermittent non-tidal streams,the District Engineer waives this criterion in writing,and the District Engineer has determined that the project complies with all terms and conditions of this NWP,and that any adverse impacts of the project on the 1 aquatic environment are minimal,both individually and cumulatively; (15) For NWP 43(Stormwater Management Facilities),the PCN must include,for the construction of new stormwater management facilities,a maintenance plan(in accordance with state and local requirements,if applicable)and a compensatory mitigation proposal to offset losses of waters of the US. For discharges that cause the loss of greater than 300 linear feet of an intermittent stream bed,to be authorized,the District Engineer must determine that the activity complies with the other terms and conditions of the NWP,determine adverse environmental effects are minimal both individually and cumulatively,and waive the limitation on stream impacts in writing before the permittee may proceed; i (16) For NWP 44(Mining Activities),the PCN must include a description of all waters of the US adversely affected by the project,a description of measures taken to minimize adverse effects to waters of the US,a description of measures taken to comply with the criteria of the NWP,and a reclamation plan(for all aggregate mining activities in isolated waters and non-tidal wetlands adjacent to headwaters and any hard rock/mineral mining activities); w.

(c) Form of Notification: The standard Individual Permit application form(Form ENG 4345)may be used as the notification but must clearly indicate that it is a PCN and must include all of the information required in(b)(1)- (18)of General Condition 13. A letter containing the requisite information may also be used. �r 7 (d) District Engineer's Decision: In reviewing the PCN for the proposed activity,the District Engineer will determine whether the activity authorized by the NWP will result in more than minimal individual or cumulative adverse environmental effects or may be contrary to the public interest. The prospective permittee may submit a proposed mitigation plan with the PCN to expedite the process. The District Engineer will consider any proposed compensatory mitigation the applicant has included in the proposal in determining whether the net adverse environmental effects to the aquatic environment of the proposed work are minimal. If the District Engineer determines that the activity complies with the terms and conditions of the NWP and that the adverse effects on the aquatic environment are minimal,after considering mitigation,the District Engineer will notify the permittee and include any conditions the District Engineer deems necessary. The District Engineer must approve any compensatory mitigation proposal before the permittee commences work. If the prospective permittee is required to submit a compensatory mitigation proposal with the PCN,the proposal may be either conceptual or detailed. If the prospective permittee elects to submit a compensatory mitigation plan with the PCN,the District Engineer will expeditiously review the proposed compensatory mitigation plan. The District Engineer must review the plan within 45 days of receiving a complete PCN and determine whether the conceptual or specific proposed mitigation would ensure no more than minimal adverse effects on the aquatic environment. If the net adverse effects of the project on the aquatic environment(after consideration of the compensatory mitigation proposal)are determined by the District Engineer to be minimal,the District Engineer will provide a timely written response to the applicant. The response will state that the project can proceed under the terms and conditions of the NWP. If the District Engineer determines that the adverse effects of the proposed work are more than minimal,then the District Engineer will notify the applicant either: (1)That the project does not qualify for authorization under the NWP and instruct the applicant on the procedures to seek authorization under an Individual Permit;(2)that the project is authorized under the NWP subject to the applicant's submission of a mitigation proposal that would reduce the adverse effects on the aquatic environment to the minimal level;or(3)that the project is authorized under the NWP with specific modifications or conditions. Where the District Engineer determines that mitigation is required to ensure no more than minimal adverse effects occur to the aquatic environment,the activity will be authorized within the 45-day PCN period. The authorization will include the ar necessary conceptual or specific mitigation or a requirement that the applicant submit a mitigation proposal that would reduce the adverse effects on the aquatic environment to the minimal level. When conceptual mitigation is included,or a mitigation plan is required under item(2)above,no work in waters of the US will occur until the District Engineer has approved a specific mitigation plan. (e) Agency Coordination: The District Engineer will consider any comments from Federal and state agencies concerning the proposed activity's compliance with the terms and conditions of the NWPs and the need for it mitigation to reduce the project's adverse environmental effects to a minimal level. For activities requiring notification to the District Engineer that result in the loss of greater than 1/2-acre of waters of the US,the District Engineer will provide immediately(e.g.,via facsimile transmission,overnight mail,or other expeditious manner)a copy to the appropriate Federal or state offices(USFWS,state natural resource or water quality agency,EPA,State Historic Preservation Officer(SHPO),and,if appropriate,the NMFS). With the exception of NWP 37,these agencies will then have 10 calendar days from the date the material is transmitted to telephone or fax the District Engineer notice that they intend to provide substantive,site-specific comments. If so contacted by an agency, the District Engineer will wait an additional 15 calendar days before making a decision on the notification. The District Engineer will fully consider agency comments received within the specified time frame,but will provide no response to the resource agency,except as provided below. The District Engineer will indicate in the administrative record associated with each notification that the resource agencies'concerns were considered. As required by section 305(b)(4)(B)of the Magnuson-Stevens Fishery Conservation and Management Act,the District Engineer will provide a response to NUTS within 30 days of receipt of any Essential Fish Habitat conservation recommendations. Applicants are encouraged to provide the Corps multiple copies of notifications to expedite agency notification. • (f) Wetland Delineations: Wetland delineations must be prepared in accordance with the current method required by the Corps(For NWP 29 see paragraph(b)(9)(iii)for parcels less than(1/4-acre in size). The permittee may ask the Corps to delineate the special aquatic site. There may be some delay if the Corps does the delineation. Furthermore,the 45-day period will not start until the wetland delineation has been completed and submitted to the Corps,where appropriate. 40 14. Compliance Certification. Every permittee who has received NWP verification from the Corps will submit a signed certification regarding the completed work and any required mitigation. The certification will be forwarded by the Corps with the authorization letter and will include: 8 Im "W (a) A statement that the authorized work was done in accordance with the Corps authorization,including any general or specific conditions; (b) A statement that any required mitigation was completed in accordance with the permit conditions;and (c) The signature of the permittee certifying the completion of the work and mitigation. 15. Use of Multiple Nationwide Permits. The use of more than one NWP for a single and complete project is prohibited,except when the acreage loss of waters of the US authorized by the NWPs does not exceed the acreage limit of the NWP with the highest specified acreage limit(e.g.if a road crossing over tidal waters is constructed under NWP 14,with associated bank stabilization authorized by NWP 13,the maximum acreage loss of waters of the US for the total project cannot exceed 1/3-acre). 16. Water Supply Intakes. No activity,including structures and work in navigable waters of the US or .w discharges of dredged or fill material,may occur in the proximity of a public water supply intake except where the activity is for repair of the public water supply intake structures or adjacent bank stabilization. 17. Shellfish Beds. No activity,including structures and work in navigable waters of the US or discharges of dredged or fill material,may occur in areas of concentrated shellfish populations,unless the activity is directly related to a shellfish harvesting activity authorized by NWP 4. 18. Suitable Material. No activity,including structures and work in navigable waters of the US or discharges of dredged or fill material,may consist of unsuitable material(e.g.,trash,debris,car bodies,asphalt,etc.)and material used for construction or discharged must be free from toxic pollutants in toxic amounts(see section 307 of the CWA). 19. Mitigation. The District Engineer will consider the factors discussed below when determining the acceptability of appropriate and practicable mitigation necessary to offset adverse effects on the aquatic environment that are more than minimal. (a) The project must be designed and constructed to avoid and minimize adverse effects to waters of the US to the maximum extent practicable at the project site(i.e.,on site). (b) Mitigation in all its forms(avoiding,minimizing,rectifying,reducing or compensating)will be required to the extent necessary to ensure that the adverse effects to the aquatic environment are minimal. (c) Compensatory mitigation at a minimum one-for-one ratio will be required for all wetland impacts requiring a PCN,unless the District Engineer determines in writing that some other form of mitigation would be more environmentally appropriate and provides a project-specific waiver of this requirement. Consistent with National policy,the District Engineer will establish a preference for restoration of wetlands as compensatory mitigation,with preservation used only in exceptional circumstances. (d) Compensatory mitigation(i.e.,replacement or substitution of aquatic resources for those impacted)will not be used to increase the acreage losses allowed by the acreage limits of some of the NWPs. For example, 1/4-acre of wetlands cannot be created to change a 3/4-acre loss of wetlands to a 1/2-acre loss associated with NWP 39 verification. However, 1/2-acre of created wetlands can be used to reduce the impacts of a 1/2-acre loss of wetlands to IM the minimum impact level in order to meet the minimal impact requirement associated with NWPs. (e) To be practicable,the mitigation must be available and capable of being done considering costs,existing technology,and logistics in light of the overall project purposes. Examples of mitigation that may be appropriate and practicable include,but are not limited to: reducing the size of the project;establishing and maintaining wetland or upland vegetated buffers to protect open waters such as streams;and replacing losses of aquatic resource functions and values by creating,restoring,enhancing,or preserving similar functions and values,preferably in the same watershed. (f) Compensatory mitigation plans for projects in or near streams or other open waters will normally include a requirement for the establishment,maintenance,and legal protection(e.g.,easements,deed restrictions)of vegetated buffers to open waters. In many cases,vegetated buffers will be the only compensatory mitigation required. Vegetated �r 9 w buffers should consist of native species. The width of the vegetated buffers required will address documented water quality or aquatic habitat loss concerns. Normally,the vegetated buffer will be 25 to 50 feet wide on each side of the stream,but the District Engineers may require slightly wider vegetated buffers to address documented water quality or habitat loss concerns. Where both wetlands and open waters exist on the project site,the Corps will determine the appropriate compensatory mitigation(e.g.,stream buffers or wetlands compensation)based on what is best for the aquatic environment on a watershed basis. In cases where vegetated buffers are determined to be the most appropriate form of compensatory mitigation,the District Engineer may waive or reduce the requirement to provide wetland compensatory mitigation for wetland impacts. (g) Compensatory mitigation proposals submitted with the"notification"maybe either conceptual or detailed. If conceptual plans are approved under the verification,then the Corps will condition the verification to require detailed plans be submitted and approved by the Corps prior to construction of the authorized activity in waters of the US. (h) Permittees may propose the use of mitigation banks,in-lieu fee arrangements or separate activity-specific compensatory mitigation. In all cases that require compensatory mitigation,the mitigation provisions will specify the party responsible for accomplishing and/or complying with the mitigation plan. 20. Spawning Areas. Activities,including structures and work in navigable waters of the US or discharges of dredged or fill material,in spawning areas during spawning seasons must be avoided to the maximum extent practicable. Activities that result in the physical destruction(e.g.,excavate,fill,or smother downstream by substantial turbidity)of an important spawning area are not authorized. 21. Management of Water Flows. To the maximum extent practicable,the activity must be designed to maintain preconstruction downstream flow conditions(e.g.,location,capacity,and flow rates). Furthermore,the activity must not permanently restrict or impede the passage of normal or expected high flows(unless the primary purpose of the fill is to impound waters)and the structure or discharge of dredged or fill material must withstand expected high flows. The activity must,to the maximum extent practicable,provide for retaining excess flows from the site,provide for maintaining surface flow rates from the site similar to preconstruction conditions,and provide for not increasing water flows from the project site,relocating water,or redirecting water flow beyond preconstruction conditions. Stream channelizing will be reduced to the minimal amount necessary,and the activity must,to the maximum extent practicable,reduce adverse effects such as flooding or erosion downstream and upstream of the project site,unless the activity is part of a larger system designed to manage water flows. In most cases, it will not be a requirement to conduct detailed studies and monitoring of water flow. This condition is only applicable to projects that have the potential to affect waterflows. While appropriate measures must be taken,it is not necessary to conduct detailed studies to identify such measures or require monitoring to ensure their effectiveness. Normally,the Corps will defer to state and local authorities regarding management of water flow. 22. Adverse Effects From Impoundments. If the activity creates an impoundment of water,adverse effects to the aquatic system due to the acceleration of the passage of water,and/or the restricting its flow shall be minimized to the maximum extent practicable. This includes structures and work in navigable waters of the US,or discharges of dredged or fill material. 23. Waterfowl Breeding Areas. Activities,including structures and work in navigable waters of the US or discharges of dredged or fill material,into breeding areas for migratory waterfowl must be avoided to the maximum extent practicable. 24. Removal of Temporary Fills. Any temporary fills must be removed in their entirety and the affected areas returned to their preexisting elevation. 25. Designated Critical Resource Waters. Critical resource waters include,NOAA-designated marine sanctuaries,National Estuarine Research Reserves,National Wild and Scenic Rivers,critical habitat for Federally listed threatened and endangered species,coral reefs,state natural heritage sites,and outstanding national resource waters or other waters officially designated by a state as having particular environmental or ecological significance and identified by the District Engineer after notice and opportunity for public comment. The District Engineer may also designate , additional critical resource waters after notice and opportunity for comment. 10 Im op (a) Except as noted below,discharges of dredged or fill material into waters of the US are not authorized by NWPs 7, 12, 14, 16, 17,21,29,31,35,39,40,42,43,and 44 for any activity within,or directly affecting,critical resource waters,including wetlands adjacent to such waters. Discharges of dredged or fill materials into waters of the Im US may be authorized by the above NWPs in National Wild and Scenic Rivers if the activity complies with General Condition 7. Further,such discharges may be authorized in designated critical habitat for Federally listed threatened or endangered species if the activity complies with General Condition 11 and the USFWS or the NMFS has concurred in a determination of compliance with this condition. (b) For NWPs 3,8, 10, 13, 15, 18, 19,22,23,25,27,28,30,33,34,36,37,and 38,notification is required in accordance with General Condition 13,for any activity proposed in the designated critical resource waters including wetlands adjacent to those waters. The District Engineer may authorize activities under these NWPs only after it is determined that the impacts to the critical resource waters will be no more than minimal. 26. Fills Within 100-Year Floodplains. For purposes of this General Condition, 100-year floodplains will be identified through the existing Federal Emergency Management Agency's(FEMA)Flood Insurance Rate Maps or FEMA-approved local floodplain maps. (a) Discharges in Floodplain;Below Headwaters. Discharges of dredged or fill material into waters of the US within the mapped 100-year floodplain,below headwaters(i.e.,5 cfs),resulting in permanent above-grade fills,are not authorized by NWPs 39,40,42,43,and 44. (b) Discharges in Floodway;Above Headwaters.

DESCRIPTION OF AUTHORIZED ACTIVITIES Temporary Construction,Access and Dewatering. Temporary structures,work and discharges,including L. cofferdams,necessary for construction activities or access fills or dewatering of construction sites;provided that the associated primary activity is authorized by the Corps of Engineers or the USCG,or for other construction activities not subject to the Corps or USCG regulations. Appropriate measures must be taken to maintain near normal r, downstream flows and to minimize flooding. Fill must be of materials,and placed in a manner,that will not be eroded by expected high flows. The use of dredged material may be allowed if it is determined by the District Engineer that it will not cause more than minimal adverse effects on aquatic resources. Temporary fill must be entirely removed to upland areas,or dredged material returned to its original location, following completion of the construction activity,and the affected areas must be restored to the pre-project conditions. Cofferdams cannot be used to dewater wetlands or other aquatic areas to change their use. Structures left in place after cofferdams are removed require a Section 10 permit if located in navigable waters of the US. (See 33 CFR Part 322). The permittee must notify the District Engineer in accordance with the "Notification"General Condition. The notification must also include a restoration plan of reasonable measures to avoid and minimize adverse effects to aquatic resources. The District Engineer will add Special Conditions,where necessary,to ensure that environmental adverse effects are .. minimal. Such conditions may include: limiting the temporary work to the minimum necessary;requiring seasonal restrictions;modifying the restoration plan;and requiring alternative construction methods(e.g. construction mats in , wetlands where practicable). (Sections 10 and 404) B. CORPS REGIONAL CONDITIONS FOR THIS NWP ' 1. Temporary fills may be in place for up to six months only,unless the applicant requests and receives approval for an extension from the District Engineer. Additional timing adjustments may be included to lessen impacts during critical times for migratory species. 2. The permittee must avoid and minimize discharges into waters of the US at the project site to the maximum extent practicable,and the"Notification"must include a written justification to the District Engineer detailing compliance with this condition,i.e.,why the discharge must occur in waters of the US and why avoidance or additional minimization cannot be achieved. 3. This NWP is prohibited from use in playa lakes,prairie potholes,vernal pools,kettles,and camas prairie wetlands or within 100 feet of any such system. An individual permit application must be submitted for proposed work in these areas. , C. EPA, PUYALLUP TRIBE AND CHEHALIS TRIBE WQC CONDITIONS FOR THIS NWP , EPA,Puyallup Tribe and Chehalis Tribe water quality certification(WQC)has been denied without prejudice. An individual WQC is required for all Section 404 activities. , D. STATE WQC CONDITIONS FOR THIS NWP State WQC has been partially denied without prejudice for this permit. An individual 401 Certification is required for projects or activities authorized under this NWP if the project/activity will likely result in any of the following adverse effects: 1. The project or activity will likely cause or contribute to an exceedance of a State water quality standard (WAC 173-201A)or sediment quality standard(WAC 173-204). The requirement to obtain an individual 401 certification shall not apply to projects or activities that are carried out in accordance with the following permits,approvals,or management practices. These projects are presumed to comply with state water quality standards including state sediment management standards: ' a. Projects or activities where the discharges authorized under this NWP are explicitly authorized or covered by a National Pollutant Discharge Elimination System permit. b. Projects,activities or portions of projects or activities designed,constructed,and maintained in accordance with the stormwater standards and practices contained in the most current version of Ecology's Stormwater Manual or an Ecology approved equivalent. c. For WSDOT in-water or over-water construction and maintenance activities, an individual 401 certification is not required for those projects carried out in compliance with conditions 2 through 4 below and the Ecology approved Implementing Agreement regarding compliance with the state of Washington Surface Water Quality Standards. 2 ' "' Compliance with this condition will be determined through receipt of a signed statement by the WSDOT project engineer or maintenance supervisor,guaranteeing that the project will meet the latest Ecology approved Water Quality Implementing Agreement for work In-Water. This statement shall be sent to the Corps of Engineers along with the JARPA application. 2. For projects/activities not designed in accordance with either Ecology's stormwater manual or an Ecology approved equivalent,or for projects where there is credible site specific information which indicates that the permits,approvals,or management practices identified above will not be sufficient to meet state water quality standards,the applicant may provide documentation with the application that the project/activity will otherwise comply with state water quality standards. An individual 401 Certification is required for .� projects which are unable to provide documentation that the project/activity will otherwise comply with state water quality standards. aw 3. Projects or activities that cause or contribute to a discharge to a waterbody on the state's list of impaired waterbodies[i.e.,the 303(d)list]and the discharge may result in further exceedances of a specific parameter the waterbody is listed for. The current list of 303(d)-listed waterbodies is available on Ecology's web site at http:i%w,,x,,A,.ecy.wa.gov/'programs%�,q%30341998/1998_by_wrias.html or by contacting Ecology's Federal Permits staff. NOTE: An individual 401 Certification will not be required if the applicant provides documentation showing that the project or activity will either not result in a discharge containing the listed parameter or,if present,the parameter will not contribute to an increased impairment of the waterbody. 4. Projects that do not incorporate structures and/or modifications beneficial for fish or wildlife habitat(e.g., soil bioengineering,biotechnical design,rock barbs,etc.) NOTE:An individual 401 certification will not be required if the project/activity is designed and constructed in accordance to guidelines developed by the Washington State Department of Fish and Wildlife. E. STATE CZM CONSISTENCY DETERMINATION CONDITIONS FOR THIS NWP The Coastal Zone Management(CZM)Consistency Determination has been partially denied without prejudice for this NWP. An individual CZM Consistency Response must be obtained for projects requiring individual 401 Certification and located within counties in the coastal zone. L F. CORPS NATIONAL GENERAL CONDITIONS FOR ALL NWPS 1. Navigation. No activity may cause more than a minimal adverse effect on navigation. 2. Proper Maintenance. Any structure or fill authorized shall be properly maintained,including maintenance to ensure public safety. r 3. Soil Erosion and Sediment Controls. Appropriate soil erosion and sediment controls must be used and maintained in effective operating condition during construction,and all exposed soil and other fills,as well as any work below the ordinary high water mark or high tide line,must be permanently stabilized at the earliest practicable date. Permittees are encouraged to perform work within waters of the United States during periods of low-flow or no-flow. 4. Aquatic Life Movements. No activity may substantially disrupt the necessary life-cycle movements of those species of aquatic life indigenous to the waterbody, including those species that normally migrate through the area, unless the activity's primary purpose is to impound water. Culverts placed in streams must be installed to maintain low flow conditions. it 3 5. Equipment. Heavy equipment working in wetlands must be placed on mats,or other measures must be taken to minimize soil disturbance. 6. Regional and Case-By-Case Conditions. The activity must comply with any regional conditions that may have been added by the Division Engineer(see 33 CFR 330.4(e))and with any case specific conditions added by the Corps or by the state or tribe in its Section 401 Water Quality Certification and Coastal Zone Management Act ' consistency determination. 7. Wild and Scenic Rivers. No activity may occur in a component of the National Wild and Scenic River ' System;or in a river officially designated by Congress as a"study river"for possible inclusion in the system,while the river is in an official study status;unless the appropriate Federal agency,with direct management responsibility for such river,has determined in writing that the proposed activity will not adversely affect the Wild and Scenic River designation,or study status. Information on Wild and Scenic Rivers may be obtained from the appropriate Federal land management agency in the area(e.g.,National Park Service,U.S.Forest Service,Bureau of Land Management,U.S. Fish and Wildlife Service). 8. Tribal Rights. No activity or its operation may impair reserved tribal rights,including,but not limited to, reserved water rights and treaty fishing and hunting rights. 9. Water Quality. (a) In certain states and tribal lands an individual 401 Water Quality Certification must be obtained or waived(See 33 CFR 330.4(c)). (b) For NWPs 12, 14, 17, 18,32,39,40,42,43,and 44,where the state or tribal 401 certification(either generically or individually)does not require or approve water quality management measures,the permittee must provide water quality management measures that will ensure that the authorized work does not result in more than minimal degradation of water quality(or the Corps determines that compliance with state or local standards,where ' applicable,will ensure no more than minimal adverse effect on water quality). An important component of water quality management includes stormwater management that minimizes degradation of the downstream aquatic system, including water quality(refer to General Condition 21 for stormwater management requirements). Another important $. component of water quality management is the establishment and maintenance of vegetated buffers next to open waters,including streams(refer to General Condition 19 for vegetated buffer requirements for the NWPs). This condition is only applicable to projects that have the potential to affect water quality. While appropriate measures must be taken,in most cases it is not necessary to conduct detailed studies to identify such measures or to require monitoring. 10. Coastal Zone Management. In certain states,an individual state coastal zone management consistency concurrence must be obtained or waived(see 33 CFR 330.4(d)). 11. Endangered Species. (a) No activity is authorized under any NWP which is likely to jeopardize the continued existence of a threatened or endangered species or a species proposed for such designation,as identified under the Federal Endangered Species Act(ESA),or which will destroy or adversely modify the critical habitat of such species. Non- , federal permittees shall notify the District Engineer if any listed species or designated critical habitat might be affected or is in the vicinity of the project,or is located in the designated critical habitat and shall not begin work on the activity until notified by the District Engineer that the requirements of the ESA have been satisfied and that the activity is authorized. For activities that may affect Federally-listed endangered or threatened species or designated critical habitat,the notification must include the name(s)of the endangered or threatened species that may be affected by the proposed work or that utilize the designated critical habitat that may be affected by the proposed work. As a result of formal or informal consultation with the FWS or NMFS the District Engineer may add species-specific regional , endangered species conditions to the NWPs. (b) Authorization of an activity by a NWP does not authorize the"take"of a threatened or endangered species as defined under the ESA. In the absence of separate authorization(e.g.,an ESA Section 10 Permit,a ' Biological Opinion with"incidental take"provisions,etc.)from the USFWS or the NMFS,both lethal and non-lethal 4 , "takes"of protected species are in violation of the ESA. Information on the location of threatened and endangered species and their critical habitat can be obtained directly from the offices of the USFWS and NMFS or their world wide web pages at http://w ww.fws.govlr9endspplendspp.html and http://www.nmfs.noaa.govlprot_res/overviewles.html respectively. 12.

No activity which may affect historic properties listed,or eligible for listing,in the National Register of Historic Places is authorized,until the District Engineer has complied with the provisions of 33 CFR part 325,Appendix C. The prospective permittee must notify the District Engineer if the authorized activity may affect any historic properties listed,determined to be eligible,or which the prospective permittee has reason to believe may be eligible for listing on the National Register of Historic Places,and shall not begin the activity until notified by the District Engineer that the requirements of the National Historic Preservation Act have been satisfied and that the activity is authorized. Information on the location and existence of historic resources can be obtained from the State Historic Preservation Office and the National Register of Historic Places(see 33 CFR 330.4(g)). For activities that may affect historic properties listed in,or eligible for listing in,the National Register of Historic Places,the notification rr' must state which historic property may be affected by the proposed work or include a vicinity map indicating the location of the historic property. 13. Notification. (a) Timing: Where required by the terms of the NWP,the prospective permittee must notify the District Engineer with a preconstruction notification(PCN)as early as possible. The District Engineer must determine if the notification is complete within 30 days of the date of receipt and can request additional information necessary to make the PCN complete only once. However,if the prospective permittee does not provide all of the requested information, then the District Engineer will notify the prospective permittee that the notification is still incomplete and the PCN review process will not commence until all of the requested information has been received by the District Engineer. The prospective permittee shall not begin the activity: 1 (1) Until notified in writing by the District Engineer that the activity may proceed under the NWP with any special conditions imposed by the District or Division Engineer;or ' (2) If notified in writing by the District or Division Engineer that an Individual Permit is required;or (3) Unless 45 days have passed from the District Engineer's receipt of the complete notification and the prospective permittee has not received written notice from the District or Division Engineer.

For discharges that cause the loss of greater than 300 linear feet of an intermittent stream bed,to be authorized,the District Engineer must determine that the activity complies with the other terms and conditions of the NWP,determine adverse environmental effects are minimal both individually and cumulatively,and waive the limitation on stream impacts in writing before the permittee may proceed; 6 r (14) For NWP 40(Agricultural Activities),the PCN must include a compensatory mitigation proposal to offset losses of waters of the US. This NWP does not authorize the relocation of greater than 300 linear-feet of existing serviceable drainage ditches constructed in non-tidal streams unless,for drainage ditches constructed in intermittent non-tidal streams,the District Engineer waives this criterion in writing,and the District Engineer has determined that the project complies with all terms and conditions of this NWP,and that any adverse impacts of the project on the aquatic environment are minimal,both individually and cumulatively; (15) For NWP 43(Stormwater Management Facilities),the PCN must include,for the construction of new stormwater management facilities,a maintenance plan(in accordance with state and local requirements,if applicable)and a compensatory mitigation proposal to offset losses of waters of the US. For discharges that cause the loss of greater than 300 linear feet of an intermittent stream bed,to be authorized,the District Engineer must determine that the activity complies with the other terms and conditions of the NWP,determine adverse environmental effects are minimal both individually and cumulatively,and waive the limitation on stream impacts in writing before the permittee may proceed; (16) For NWP 44(Mining Activities),the PCN must include a description of all waters of the US adversely affected by the project,a description of measures taken to minimize adverse effects to waters of the US,a description of measures taken to comply with the criteria of the NWP,and a reclamation plan(for all aggregate mining activities in isolated waters and non-tidal wetlands adjacent to headwaters and any hard rock/mineral mining activities); (17) For activities that may adversely affect Federally-listed endangered or threatened species,the PCN must include the name(s)of those endangered or threatened species that may be affected by the proposed work or utilize the designated critical habitat that may be affected by the proposed work;and (18) For activities that may affect historic properties listed in,or eligible for listing in,the National Register of Historic Places,the PCN must state which historic property may be affected by the proposed work or include a vicinity map indicating the location of the historic property. (c) Form of Notification: The standard Individual Permit application form(Form ENG 4345)may be used as the notification but must clearly indicate that it is a PCN and must include all of the information required in(b)(1)- (18)of General Condition 13. A letter containing the requisite information may also be used. (d) District Engineer's Decision: In reviewing the PCN for the proposed activity,the District Engineer will determine whether the activity authorized by the NWP will result in more than minimal individual or cumulative adverse environmental effects or may be contrary to the public interest. The prospective permittee may submit a proposed mitigation plan with the PCN to expedite the process. The District Engineer will consider any proposed compensatory mitigation the applicant has included in the proposal in determining whether the net adverse environmental effects to the aquatic environment of the proposed work are minimal. If the District Engineer determines that the activity complies with the terms and conditions of the NWP and that the adverse effects on the aquatic environment are minimal,after considering mitigation,the District Engineer will notify the permittee and t include any conditions the District Engineer deems necessary. The District Engineer must approve any compensatory mitigation proposal before the permittee commences work. If the prospective permittee is required to submit a compensatory mitigation proposal with the PCN,the proposal may be either conceptual or detailed. If the prospective permittee elects to submit a compensatory mitigation plan with the PCN,the District Engineer will expeditiously review the proposed compensatory mitigation plan. The District Engineer must review the plan within 45 days of receiving a complete PCN and determine whether the conceptual or specific proposed mitigation would ensure no more than minimal adverse effects on the aquatic environment. If the net adverse effects of the project on the aquatic environment(after consideration of the compensatory mitigation proposal)are determined by the District Engineer to be minimal,the District Engineer will provide a timely written response to the applicant. The response will state that the project can proceed under the terms and conditions of the NWP. If the District Engineer determines that the adverse effects of the proposed work are more than minimal,then the District Engineer will notify the applicant either: (1)That the project does not qualify for authorization under the NWP and instruct the applicant on the procedures to .. seek authorization under an Individual Permit;(2)that the project is authorized under the NWP subject to the applicant's submission of a mitigation proposal that would reduce the adverse effects on the aquatic environment to the minimal level;or(3)that the project is authorized under the NWP with specific modifications or conditions. Where the District Engineer determines that mitigation is required to ensure no more than minimal adverse effects occur to the Irr 7 r.. aquatic environment,the activity will be authorized within the 45-day PCN period. The authorization will include the necessary conceptual or specific mitigation or a requirement that the applicant submit a mitigation proposal that wouldt reduce the adverse effects on the aquatic environment to the minimal level. When conceptual mitigation is included,or a mitigation plan is required under item(2)above,no work in waters of the US will occur until the District Engineer has approved a specific mitigation plan. (e) Agency Coordination: The District Engineer will consider any comments from Federal and state agencies concerning the proposed activity's compliance with the terms and conditions of the NWPs and the need for mitigation to reduce the project's adverse environmental effects to a minimal level. For activities requiring notification to the District Engineer that result in the loss of greater than 1/2-acre of waters of the US,the District Engineer will provide immediately(e.g.,via facsimile transmission,overnight mail,or other expeditious manner)a copy to the appropriate Federal or state offices(USFWS,state natural resource or water quality agency,EPA,State Historic Preservation Officer(SHPO),and,if appropriate,the NMFS). With the exception of NWP 37,these agencies will then have 10 calendar days from the date the material is transmitted to telephone or fax the District Engineer notice that they intend to provide substantive,site-specific comments. If so contacted by an agency,the District Engineer will wait an additional 15 calendar days before making a decision on the notification. The District Engineer will fully consider agency comments received within the specified time frame,but will provide no response to the resource agency,except as provided below. The District Engineer will indicate in the administrative record associated with each notification that the resource agencies'concerns were considered. As required by section 305(b)(4)(13)of the Magnuson-Stevens Fishery Conservation and Management Act,the District Engineer will provide a response to NMFS within 30 days of , receipt of any Essential Fish Habitat conservation recommendations. Applicants are encouraged to provide the Corps multiple copies of notifications to expedite agency notification. (f) Wetland Delineations: Wetland delineations must be prepared in accordance with the current method , required by the Corps(For NWP 29 see paragraph(b)(9)(iii)for parcels less than(1/4-acre in size). The permittee may ask the Corps to delineate the special aquatic site. There may be some delay if the Corps does the delineation. Furthermore,the 45-day period will not start until the wetland delineation has been completed and submitted to the Corps,where appropriate. 14. Compliance Certification. Every permittee who has received NWP verification from the Corps will submit a signed certification regarding the completed work and any required mitigation. The certification will be forwarded by the Corps with the authorization letter and will include: (a) A statement that the authorized work was done in accordance with the Corps authorization,including any general or specific conditions; (b) A statement that any required mitigation was completed in accordance with the permit conditions;and (c) The signature of the permittee certifying the completion of the work and mitigation. 15. Use of Multiple Nationwide Permits. The use of more than one NWP for a single and complete project is prohibited,except when the acreage loss of waters of the US authorized by the NWPs does not exceed the acreage limit of the NWP with the highest specified acreage limit(e.g.if a road crossing over tidal waters is constructed under NWP 14,with associated bank stabilization authorized by NWP 13,the maximum acreage loss of waters of the US for the total project cannot exceed 1/3-acre). 16. Water Supply Intakes. No activity,including structures and work in navigable waters of the US or discharges of dredged or fill material,may occur in the proximity of a public water supply intake except where the activity is for repair of the public water supply intake structures or adjacent bank stabilization. 17. Shellfish Beds. No activity,including structures and work in navigable waters of the US or discharges of ' dredged or fill material,may occur in areas of concentrated shellfish populations,unless the activity is directly related to a shellfish harvesting activity authorized by NWP 4. 8 18. Suitable Material. No activity,including structures and work in navigable waters of the US or discharges of dredged or fill material,may consist of unsuitable material(e.g.,trash,debris,car bodies,asphalt,etc.)and material used for construction or discharged must be free from toxic pollutants in toxic amounts(see section 307 of the CWA). 19. Mitigation. The District Engineer will consider the factors discussed below when determining the acceptability of appropriate and practicable mitigation necessary to offset adverse effects on the aquatic environment that are more than minimal. (a) The project must be designed and constructed to avoid and minimize adverse effects to waters of the US to the maximum extent practicable at the project site(i.e.,on site). r (b) Mitigation in all its forms(avoiding,minimizing,rectifying,reducing or compensating)will be required to the extent necessary to ensure that the adverse effects to the aquatic environment are minimal. (c) Compensatory mitigation at a minimum one-for-one ratio will be required for all wetland impacts requiring a PCN,unless the District Engineer determines in writing that some other form of mitigation would be more R environmentally appropriate and provides a project-specific waiver of this requirement. Consistent with National policy,the District Engineer will establish a preference for restoration of wetlands as compensatory mitigation,with preservation used only in exceptional circumstances. (d) Compensatory mitigation(i.e.,replacement or substitution of aquatic resources for those impacted)will not be used to increase the acreage losses allowed by the acreage limits of some of the NWPs. For example, 1/4-acre of wetlands cannot be created to change a 3/4-acre loss of wetlands to a 1/2-acre loss associated with NWP 39 verification. However, 1/2-acre of created wetlands can be used to reduce the impacts of a 1/2-acre loss of wetlands to the minimum impact level in order to meet the minimal impact requirement associated with NWPs. (e) To be practicable,the mitigation must be available and capable of being done considering costs,existing technology,and logistics in light of the overall project purposes. Examples of mitigation that may be appropriate and practicable include,but are not limited to: reducing the size of the project;establishing and maintaining wetland or upland vegetated buffers to protect open waters such as streams;and replacing losses of aquatic resource functions and ' values by creating,restoring,enhancing,or preserving similar functions and values,preferably in the same watershed. (0 Compensatory mitigation plans for projects in or near streams or other open waters will normally include a requirement for the establishment,maintenance,and legal protection(e.g.,easements,deed restrictions)of vegetated buffers to open waters. In many cases,vegetated buffers will be the only compensatory mitigation required. Vegetated buffers should consist of native species. The width of the vegetated buffers required will address documented water quality or aquatic habitat loss concerns. Normally,the vegetated buffer will be 25 to 50 feet wide on each side of the stream,but the District Engineers may require slightly wider vegetated buffers to address documented water quality or habitat loss concerns. Where both wetlands and open waters exist on the project site,the Corps will determine the appropriate compensatory mitigation(e.g.,stream buffers or wetlands compensation)based on what is best for the aquatic environment on a watershed basis. In cases where vegetated buffers are determined to be the most appropriate form of compensatory mitigation,the District Engineer may waive or reduce the requirement to provide wetland compensatory mitigation for wetland impacts. (g) Compensatory mitigation proposals submitted with the"notification"may be either conceptual or detailed. If conceptual plans are approved under the verification,then the Corps will condition the verification to require detailed plans be submitted and approved by the Corps prior to construction of the authorized activity in waters of the US. (h) Permittees may propose the use of mitigation banks,in-lieu fee arrangements or separate activity-specific compensatory mitigation. In all cases that require compensatory mitigation,the mitigation provisions will specify the party responsible for accomplishing and/or complying with the mitigation plan. �r 9 20. Spawning Areas. Activities,including structures and work in navigable waters of the US or discharges of dredged or fill material,in spawning areas during spawning seasons must be avoided to the maximum extent practicable. Activities that result in the physical destruction(e.g.,excavate,fill,or smother downstream by substantial turbidity)of an important spawning area are not authorized. 21. Management of Water Flows. To the maximum extent practicable,the activity must be designed to maintain preconstruction downstream flow conditions(e.g.,location,capacity,and flow rates). Furthermore,the activity must not permanently restrict or impede the passage of normal or expected high flows(unless the primary purpose of the fill is to impound waters)and the structure or discharge of dredged or fill material must withstand ' expected high flows. The activity must,to the maximum extent practicable,provide for retaining excess flows from the site,provide for maintaining surface flow rates from the site similar to preconstruction conditions,and provide for not increasing water flows from the project site,relocating water,or redirecting water flow beyond preconstruction conditions. Stream channelizing will be reduced to the minimal amount necessary,and the activity must,to the maximum extent practicable,reduce adverse effects such as flooding or erosion downstream and upstream of the project site,unless the activity is part of a larger system designed to manage water flows. In most cases, it will not be a requirement to conduct detailed studies and monitoring of water flow. This condition is only applicable to projects that have the potential to affect waterflows. While appropriate measures must be taken,it is not necessary to conduct detailed studies to identify such measures or require monitoring to ensure their effectiveness. Normally,the Corps will defer to state and local authorities regarding management of water flow. 22. Adverse Effects From Impoundments. If the activity creates an impoundment of water,adverse effects to the aquatic system due to the acceleration of the passage of water,and/or the restricting its flow shall be minimized to the maximum extent practicable. This includes structures and work in navigable waters of the US,or discharges of dredged or fill material. • 23. Waterfowl Breeding Areas. Activities,including structures and work in navigable waters of the US or discharges of dredged or fill material,into breeding areas for migratory waterfowl must be avoided to the maximum extent practicable. ON 24. Removal of Temporary Fills. Any temporary fills must be removed in their entirety and the affected areas ' returned to their preexisting elevation. 25. Designated Critical Resource Waters. Critical resource waters include,NOAA-designated marine sanctuaries,National Estuarine Research Reserves,National Wild and Scenic Rivers,critical habitat for Federally listed ' threatened and endangered species,coral reefs,state natural heritage sites,and outstanding national resource waters or other waters officially designated by a state as having particular environmental or ecological significance and identified by the District Engineer after notice and opportunity for public comment. The District Engineer may also designate ' additional critical resource waters after notice and opportunity for comment. (a) Except as noted below,discharges of dredged or fill material into waters of the US are not authorized by NWPs 7, 12, 14, 16, 17,21,29,31,35,39,40,42,43,and 44 for any activity within,or directly affecting,critical resource waters,including wetlands adjacent to such waters. Discharges of dredged or fill materials into waters of the US may be authorized by the above NWPs in National Wild and Scenic Rivers if the activity complies with General Condition 7. Further, such discharges may be authorized in designated critical habitat for Federally listed threatened or endangered species if the activity complies with General Condition 11 and the USFWS or the NMFS has concurred in a determination of compliance with this condition. (b) For NWPs 3,8, 10, 13, 15, 18, 19,22,23,25,27,28,30,33,34,36,37,and 38,notification is required in accordance with General Condition 13,for any activity proposed in the designated critical resource waters including wetlands adjacent to those waters. The District Engineer may authorize activities under these NWPs only after it is determined that the impacts to the critical resource waters will be no more than minimal. 26. Fills Within 100-Year Floodplains. For purposes of this General Condition, 100-year floodplains will be identified through the existing Federal Emergency Management Agency's(FEMA)Flood Insurance Rate Maps or FEMA-approved local floodplain maps. , 10 , (a) Discharges in Floodplain;Below Headwaters. Discharges of dredged or fill material into waters of the US within the mapped 100-year floodplain,below headwaters(i.e.,5 cfs),resulting in permanent above-grade fills,are not authorized by NWPs 39,40,42,43,and 44. (b) Discharges in Floodway;Above Headwaters. Discharges of dredged or fill material into waters of the US within the FEMA or locally mapped floodway,resulting in permanent above-grade fills,are not authorized by NWPs 39,40,42,and 44. (c) The permittee must comply with any applicable FEMA-approved state or local floodplain management requirements. 27. Construction Period. For activities that have not been verified by the Corps and the project was commenced or under contract to commence by the expiration date of the NWP(or modification or revocation date),the work must be completed within 12-months after such date(including any modification that affects the project). For activities that have been verified and the project was commenced or under contract to commence within the verification period,the work must be completed by the date determined by the Corps. For projects that have been verified by the Corps,an extension of a Corps approved completion date maybe requested. This request must be submitted at least one month before the previously approved completion date. G. CORPS REGIONAL GENERAL CONDITIONS FOR ALL NWPS 1. Mature Forested and Bog and Bog-like Wetlands.

CITY OF RENTON SURVEY CONTROL NETWORK The City of Renton Survey Control Network is the result of a three year project by the Technical Services Section of the Planning & Technical Services Division of the Planning/Building/Public Works Department and several private surveying firms working for the city. The purpose of this network is to provide an accessible common datum for all public and private projects within the city. Thus facilitating city wide infrastructure management and analysis and assuring compatibility between the various utility systems and system projects. This project started in 1992 with the formation of a Horizontal and Vertical Control Network Committee to prepare a plan for the development and maintenance of a Survey Control Network for the City. The committee members were: Robert Anderson PLS; Bush, Roed & Hitchings, Inc., Carrie Davis; Technical Services Section(Recorder), i Abdoul Gafour; Utility Systems Division, Arneta Henninger; Plan Review Section, Development Services Division, Jae Lee; Transportation Systems Division, Robert Mac Onie; Technical Services Section(Chairman), Jon Warren PLS; Dodds Engineers, Inc., Dennis Wegenast; National Geodetic Survey. The committee developed the standards, specifications and phasing for all ensuing work. All survey work meets the requirements specified by the Federal Geodetic Control Committee in Standards and Specifications for Geodetic Control Networks dated September 1984. The project was split into three phases: 1) monument recovery, 2) horizontal control and 3) vertical control. The monument recovery project was performed by Dodds Engineers, Inc., under the direction of Jon Warren PLS in 1992 and early 1993. This project identified existing Public Land Survey System comer monuments and other monuments (NGS, C&GS, King County, City of Bellevue, major intersections and those located near current and proposed capital improvement projects) important to the development of a survey control network. In most cases, street centerline monuments .. were selected for both horizontal and vertical control due to stability and maintenance considerations. The second and third phases ran concurrently during 1993 & 1994. The horizontal control phase was executed by Bush, Roed & Hitchings, under the direction of Robert Anderson PLS, using Global Positioning Systems (GPS) technology per the Federal Geodetic Control Subcommittee Standards for GPS control surveys as defined in Q Geometric Geodetic Accuracy Standards & Specifications for Using GPS Relative Positioning Techniques dated August 1, 1989. This phase established NAD 1983/1991, Washington State Plane, 2nd Order, I st Class, northing and easting values for 122 monuments in and TS_SERVER//SYS2\M"S\83m\conVol scn.doc i 2 May 2000 rr around the City. our NAD 1983/1991 National Geodetic Survey M ty� y (NGS) high precision geodetic network (HPGN) monuments (BROWN, PT B 1962, HAFF and MUD MTN) controlled the GPS survey. All coordinates show are "Washington Coordinate System of 1983/1991,North Zone." The vertical control phase was performed by Triad Associates, under the direction of Brad Freeman PLS, using a Wild NA2000 automatic auto reading level and Star*Lev adjustment software. This phase established NAVD 1988, 3rd Order, 1st Class, elevations on 190 monuments in and around the City with 70 of these being horizontal. Mr control monuments as well. The leveling project was divided into seven primary interdependent loops connected at a minimum of two points with common benchmarks. Additional legs were run across the primary loops tying into two benchmarks at both ends. A total of 15 NGS benchmarks were part of the network, four of which were held in the final adjustment (NGS Archive Numbers SY0232, SY0162, SY0163 and SY0617) and provided substantial agreement(less than or equal to 5mm) with 5 others. The City, in 1995, will have reference points set for all Survey Control Network street centerline monuments not currently referenced. Over the next several years monuments in need of upgrade will be reset as part of an ongoing maintenance program or where capital improvement projects would likely disturb them. As an adjunct to the Survey Control Network the city has developed the enclosed Surveying Standards. Al Hebrank of Hebrank & Associates developed the first draft of these standards which were modified to require the use of the Survey Control Network for all public and private development projects within the city and define the responsibilities of the surveyor in the establishment of new monuments and their r associated records. The standards have been reviewed by at least ten licensed surveyors for completeness and suitability. The City of Renton and its urban growth area lie between latitudes 47° 25' North to the south and 47° 32' 30" North to the north. In most cases the combined scale factor (elevation and grid scale) throughout this area can be treated as equal to 1.0000000. Table 1. shows the grid scale factors for each minute of latitude in the Renton area identified above. Please note that the relative accuracy for the grid scale factors is approximately 1 in 60,000 at 470 25' N to the south and 1 in 111,000 at 47° 33' N to the north and thus for, most survey work will have no impact on surveys covering less than 1.5 miles. �r► r a TS_SERVER//SYS2\MAPS\83m\controNcn.doc it 2 May 2000 TABLE 1.

When combined with the worst case grid scale factor of 0.99999195 it yields a combined factor of 0.99995998 for a relative accuracy of approximately 1 in 25,000. It should be noted that Washington state uses the US survey foot and the conversion between feet and meters is 3937/1200 or 3.28083333 feet per meter. i. An analysis of the differences between NGVD 1929 and NAVD 1988 elevations in and around Renton yields a conversion factor of+1.092 meters going from NGVD 1929 to NAVD 1988. The information in this document has been extensively reviewed but there is always the possibility that some particulars of the monument locations, descriptions or values are either misleading or incorrect.
