However SG12 calls for 18" willow shrubs. I thought the plans would call for willow stakes, not shrubs. / /e., e4s E;elf d1/e-&,f j-t d elc l,, My comment on coordinating the riprap and plantings was not addressed completely. However, adjusting the riprap/planting boundary line can be handled as a field directive that only affects the quantity to be paid. The WDFW permit may specify that plantings extend under edges of the bridge. �QI�C GS d14 L My comment regarding silt fence along Springbrook reek was not addressed (Comment #7 of 12/4/97 memo to Joe A). *4.,, & du/fhj Section 8-32.3(7)conflicts with the completion date listed for entire project in the Call for Bids, Dwg. A4, and other locations. There should be no timing issue for the wetland plantings since they will be irrigated and planting can start sooner that non-irrigated plantings. However, a completion date of Sept 30 only gives 15 days for plantings to be done along the creek and other non-irrigated areas according to Section 8-02. Is this enough time? � �h Sy,el / �r wo.� ayl a�F Al1°`i e.f 'p7 t 36 Jok k.�Gl �e '✓�"`^ `� We need to specify that water tight joints (air testable) are to be used for LCPE pipe (as opposed to soil tight). !�`r�ce4r ,, <�,e� (,wsro- sr„d) ram-,.., Section 8-32.3(10) calls for the contractor to remove the temporary irrigation when directed by the Engineer. The irrigation system won't probably be removed until after the contract guarantee period is over. How can we require the contractor to do work after the contract is accepted and there is no plant maintenance bid item? Don't we need to specify an interim draina a outlet (i.e., to Boeing) in the event the Corps permit is not obtained by the time work is to start? An1( L S1� aS c�d,�.�¢ o'��✓ lew—* 4."f l55a.ej.

The Virginia Creeper planting is a roadway cost item as are all plantings on the landward side of the trail (see Schedule B limits on SG4). The schedule of prices needs to be revised to reflect this. 2. A pay item for Live Willow Cuttings needs to be added to Schedule B. Shapiro is working on a special provision for willow cuttings to Section 8-31. �3. The relationship between Section 8-31 and Section 8-02 is unclear. Section 8-31 is said to cover the planting work along the creek but payment and many of the construction requirements for the plantings is listed under Section 8-02.5. It would be better to include the special provisions related to the planting along the creek in Section 8-02 (as was done for seeding in Section 8-01) and leave / Section 8-31 to pertain only to the woody debris. �/ 4. I have noted suggested locations for Douglas Fir on plan SG12. Please add some Douglas Fir it will not compromise the trails or walls. ,15. Please stop the riprap 5 or so feet from under edge of bridge and plant the area? WDFW will be looking for this. Shapiro and Entranco need to coordinate the riprap and planting limits so that they are in agreement. ✓6. Payment for clear plastic covering in Section 8-01.5 of the WSDOT spec is intended for a one time install and remove. If the covering must be installed at end of each work day then we need to amend Section 8-01.5 also. Maybe it would be better to say that the labor is to be paid under the TESC force account bid item, but the material to be under the clear plastic cover item. 7. Do we really need silt fence at Springbrook Creek if we are covering the soil with plastic at the end of each work day? Please check again with WDFW to see if only one measure is acceptable and which of the two measures is preferred. I think using both measures is excessive. ,,�8. Since soil amendments are being used, we need to note on SG2 that finish grades shown on the plans are to be as measured after placement of soil amendments per Section 8-01 of the specifications for the area within the Schedule B limits shown on SG4. �9. The Engineer's estimate for item B5 is equivalent to the amount listed in Schedule A. This must be a copying error as the amount seems much too high for the Schedule B work. Items B9 and B 18 also seem high when compared to Schedule A. Other comments are as noted on the attached copies of the plans and specifications.

The conclusions reached during that meeting and the additional direction received from Scott Woodbury the same day are summarized here. Per Kato & Warren's bid proposal, Schedule A is for roadway items, and Schedule B is for the channel widening items of work. On the west side of the creek, all grading to the stream side of the trail shoulder was agreed to be included in Schedule B, except that the grading on this side of the creek in the shadow of the bridge is to be included in Schedule A. All channel grading on the east side of the creek is Schedule B work. All riprap and other slope stabilization items under the bridge are included in Schedule A. All woody debris are included in Schedule B. It was agreed that the excavation, shoring, modular block wall, and backfill for Wall E would be included in Schedule B, while Schedule A will include the railing seat and handrail at this location. Similarly, Schedule B will include all excavation, shoring, modular block wall, and backfill for Walls G and H. The removal of a portion of the existing retaining wall near Wall E will be included in ScheduleX-& „ The parties involved agreed that the "Schedule A & B Definition" shown in the plans is a fair division of bid items between the roadway and channel projects.

Show the same note used for Wall G on both Wall E and H as well as on Wall G. Shoring/extra excavation would need to be added to the note as being a Schedule B cost unless it is to remain incidental to the wall cost as it was in the 95% specification submittal. 2. Show all of the area under the west side of the bridge as being under Schedule A, except that woody debris is to be Schedule B. cc: Lin Wilson Ron Straka THE CITY OF RENTON DEPARTMENT OF PLANNING/BUILDING/PUBLIC WORKS FIFTH FLOOR 200 MILL AVENUE SOUTH RENTON, WASHINGTON 98055-2189 FAX: (425) 277-4428 To: Barry Knight Company: Kato & Warren Phone: (206) 448-4200 Fax: (206) 728_ SCOS From: Lin Wilson Organization: City of Renton Phone: (425) 277-6223 Fax: (425) 277-4428 Date: November 10, 1997 Pages including this cover page: 3 Subject: Oakesdale Avenue - SW 16th Street to SW 27th Street Comments: Attached are sketches showing the alignment to be adopted for the trail relocation immediately south of the Oakesdale Avenue bridge over Springbrook Creek. The alignment shown is designed to: 1. Provide 8 feet clear headroom beneath the bridge girders soffit 2. Limit the grade on the trail to 5 percent maximum, and 3. Minimize excavation in the vicinity of the existing drainage vault. The revised alignment moves a section of the profile 40 feet to the north and requires a slight reconfiguration of Wall H, and steepening of the channel excavation slopes (keeping them within 1 V:3H). Also note that there is a penetration of Wall H by the existing outlet pipe from the drainage vault. Treatment of this penetration should be detailed, preferably on the MSE wall system manufacturer's submittals. This direction should bring to a conclusion a debate that has been unduly prolonged.

Phil Schneider is only looking for the creek mitigation plan per his October 23 letter to the Corps. I will not review the WI-W5 drawings until they address all of my comments to the 95% submittal so that I don't have to repeat my comments. If the consultant has a rationale for why a comment does not need to be addressed, then I would like to be informed of the reason why in a phone call or in writing. The WDFW package only need to include the following plans: • channel plan(SG2) • cross sections(SG4) • woody debris and planting plans(currently W6) • permanent erosion control measures(currently EC3) The cover letter transmitting the WDFW package should also identify important construction issues that may need to be reflected in the HPA. These issues include: • Dewatering and stream flow bypass plan. We are not proposing to bypass the stream during construction and need WDFW approval of this plan. Installation of the woody debris and riprap under the bridge will require some work below the ordinary high water, but bypassing the flow in a pipe would cause more impact to the stream than constructing at the edge of the water. • Construction schedule. If needed, we should request that the HPA allow some work to be completed outside the anticipated June 15 to September 15 fisheries window (see my comment to sheet EC3 regarding completing work under the bridge). The SG2 and SG4 drawings need to be updated per the City's comments on the 95% drawings. The bridge profile(piling, abutments, and superstructure)need to be shown in the appropriate sections. I request that all creek related drawings be included in the SG drawing series, followed by the wall detail sheets. Why didn't we use more of the plant types Phil Schneider already approved for the Drainage District No. 1? Bob Mahn,Oakesdale Extension/Springbrook Creek Widening Project d Comments to Draft WDFW Permit Drawing Package Page 2 SPECIFIC COMMENTS(see also comments on the attached drawings): Sheet W6(change to SG??) Plan view The planting plan need to be at 1"=20' scale and show the planting zones using hatch patterns and plant symbols as necessary to be clear where certain plant material are to be installed. Use a numeric or smaller symbol to show the woody debris locations so other information on the drawing will be more visible. I suggest that the short transition areas from widened channel to existing grade south of the bridge be revegetated using willow stakes since the area will be regraded again when the channel widening is extended in the future. No trees are to be planted below elevation 9. Only seven locations for woody debris are required. I suggest the locations marked in red on a copy of the plan. The locations in term of the channel stationing are: 666+55 left, 667+35 left, 667+70 right, 668+20 left, 669+00 left, 669+50 left, and 670+00 left. I thought we were going to provide temporary irrigation to the channel plantings. Please let me know whether temporary irrigation is feasible, what type of system is recommended, and what it would cost. Stream bank planting detail 1. This detail is unclear to me. The elevations are not labeled as such and the planting only is shown to elevation 10. The plant locations relative to elevation would be better shown in the sections on SG4. A table should also be included similar to the W5 sheet for the wetlands. Use hatch patterns to show the different planting zones on the plan view drawing. There needs to be some detail or note that shows how the plantings are to be located relative to the trail and walls. How far under the bridge can be expect plantings to survive? Ten feet? We need to clearly show where the plantings and riprap boundaries are(coordinate with the information currently on EC3). Why don't we also use cuttings from native willows just upstream of the project area? There is an abundant supply. Revise details 2 to 5 based on the attached schematic drawing for woody debris. We should specify the average width dimension for the root wad to be 3 times dbh. Sheet EC3 (change to SG??) The geotextile erosion control blanket, currently shown as Coir matting, only needs to be used from the OHW to elevation 8, not in all regraded areas. Other areas only need hydroseed (covered with a 2"thick loose layer of straw)and plantings for permanent erosion control. I wish to use a generic material specification such as what I provided Entranco from our previous channel widening job, rather than specifying Coir or equal. Coir is very expensive and is more Bob Mahn, Oakesdale Extension/Springbrook Creek Widening Project Comments to Draft WDFW Permit Drawing Package Page 3 appropriate in bioengineering applications where strength is important, not as an erosion control blanket. Do we need to use wood stakes to anchor the erosion control blanket? It seems that wire staples would be less expensive and easier to use. Installing filter fabric fence along the OHW will be difficult to install, require work below the OHW, and present an obstruction to flows in the channel. I also question its effectiveness relative to just using well planned construction sequencing. I would rather have the specifications require the contractor to expose only limited areas at a time and install the erosion control blanket on the completed portions as soon as possible. Plastic sheeting anchored with sandbags could also be used to protect exposed areas if necessary. The riprap should be constructed with a toe similar to the detail used on sheet 5 of the SW Grady Way to SW 16th Street previous channel widening project plans provided to Entranco. The riprap may not have to be hand-placed since the work may be done before the bridge girders are placed depending upon the construction schedule for the bridge. This should be looked into. At a minimum,we should try to pave the trail before the girders are set.

The current design plans use a maximum grade of 8 percent to bring the trail under the bridge. Apparently, there has 9 a 0 0 4 been some concern expressed by the City of Renton Parks Department that an 8 percent grade is unsuitable based on the American Disabilities Act (ADA). T E L E P H 0 N E It is important to note that the ADA Handbook published by the Equal Employment 2 0 6 Opportunity Commission and the U.S. Department of Justice is generally intended to 4 S 4 5 6 0 0 be applied to building and facility construction, not necessarily transportation projects in public right-of-way. There are some elements of the Handbook which are useful reference material, but trails and sidewalks do not have to conform strictly to the TO L L F X E E direction which is provided therein for buildings and facilities. The U.S. Architectural 800 and Transportation Barriers Compliance Board is the group tasked with implementing 4 S 4 S 6 0 1 rules that incorporate the American with Disabilities Act Accessibility Guidelines (ADAAG). On October 9, 1997, Jerrod Snyder of our office contacted Paul Beatty of the Compliance Board to find out if there are any specific requirements of ADA that FAX would govern the Oakesdale Trail gradients. Paul's response was that, at this point in 206 time, there are no specific federal guidelines governing trail gradient. 4 5 4 0 2 2 0 The recently published Bulletin #7:Accessible Rights-of-Way by the Compliance Board recommends that a gradient of 5 percent be utilized when possible on sidewalks, but that a maximum slope of 8.33 percent is permissible (page 6, attached). It should be noted that this same Bulletin cites the American Association of State Highway and Transportation Officials (AASHTO) A Policy on Geometric Design of Highways and Streets as a guide for the design of pedestrian facilities. In the State of Washington, many elements of the AASHTO Guide have been incorporated into the Washington State Department of Transportation's Design Manual. We have utilized the Design Manual as our principle source of design criteria on the subject of gradient. The WSDOT Design Manual stipulates a maximum grade of 10 percent on walking and hiking trails (Section 1020(4), page 1020-9). As currently ARIZONA designed, the section of trail with a grade of 8 percent is relatively short, approximately I D A H 0 WASHINGTON Joe Armstrong October 14, 1997 Page 2 78 feet in length. This section was designed to minimize cost, and to raise the trail up out of the potential flood zone as quickly as possible. Another resource on this topic is the Washington State Local Agency Guidelines LAG manual) which cites that running slope of sidewalks is to be the "Minimum feasible slope consistent with slopes established by the adjacent roadway". This approach avoids the requirement of any maximum allowable slope (Page 9 of the City and County Design Standards section). This same source also clarifies that the uniform building codes and ADA style requirements are for pedestrian paths off public right-of- ways. This information is intended to provide background to the discussion which occurred last week between our design staff, Lin Wilson, and Scott Woodbury of the City of Renton, regarding the appropriateness of a 8 percent grade for the trail. Enclosed are copies of selected sections of each of the above-referenced resources. If we can provide any additional information, please contact either myself or Peter De Boldt at (425) 454-5600.

New Sidewalks • Minimum Width—60 inches continuous clear width or 36 inches clear width with (when provided) 60 inch by 60 inch clear passing spaces at 200-foot minimum intervals. • Surface—Firm,stable,and slip resistant. • Crosdopes— 1:50(2%)maximum. Running Slope—Minimum feasible slope consistent with slopes established by the adjacent roadway. • Buffer—Separation from vehicular ways by curbs or other barriers. Note: For temporary work or alterations to existing sidewalks or pedestrian facilities,refer to ADA rules.For pedestrian paths off public rights-of-ways,the designer should refer to uniform building codes and WAC 51-30 forthe appropriate standards.

GENERAL REQUIREMENTS Fibers (threads and yarns) used in the manufacture of geotextile shall consist of synthetic polymers composed of at least 85 percent by weight polypropylenes, polyesters, polyamides, polyethylene, polyolefins, or polyvinylidene- chlorides. They shall be formed into a stable network of filaments or yarns retaining dimensional stability relative to 4 each other. The geotextile shall be free of defects and conform to the physical requirements contained in Tables 1 and 2 . The geotextile shall be free of any chemical treatment or coating that significantly reduces its porosity. Fibers shall contain stabilizers and/or inhibitors to enhance resistance to ultraviolet light. Thread used for factory or field sewing shall be of contrasting color to the fabric and made of high strength Polypropylene, polyester, or polyamide thread. Thread shall be as resistant to ultraviolet light as the geotextile being sewn. 3 . CLASSIFICATION Geotextiles shall be classified based on the method used to place the threads or yarns forming the fabric. The geotextiles will be grouped into the types described below. a. Woven. Fabrics formed by the uniform and regular interweaving of the threads or yarns in two directions. Woven fabrics shall be manufactured from monofilament yarn formed into a uniform pattern with distinct and measurable j openings, retaining their position relative to each other. The edges of fabric shall be selvedged or otherwise finished to prevent the outer yarn from unraveling. b. Nonwoven. Fabrics formed by a random placement of threads in a mat and bonded by heat-bonding, resin-bonding, or needle punching. i i /(j)3P 7 'FAX TRANSMITTAL MEMO . at P?oes 10 3CS-NEH-20 _ MC 59 Af , 1 8/91 .(�+o Cod S COMPANY _ f PHONE# l iAX 8 FAX 01 /I J V' �`P�L irpvn A��N1vkS jell Nonwoven fabrics shall be manufactured from individual fibers formed into a random pattern with distinct but variable small ) openings, retaining their position relative to each other when bonded by needle punching, heat, or resin bonding. The use of nonwovens, other than the needle punched geotextiles, is somewhat restricted (see Note 3 on Table 2) . 4 . SAMPLING AND TESTING The geotextile shall meet the specified requirements (Table 1 or 2) for the product style shown on the label.

GEOTEXTILE 1. SCOPE This work shall consist of furnishing all materials, equipment, and labor necessary for the installation of Igeotextiles. 2. 2UALJTy fGeotextiles shall conform to the requirements of Material Specification 592 and this specification. 3 . STORAGE Prior to use, the geotextile shall be stored in a clean dry place, out of direct sunlight, not subject to extremes of either hot or cold, and with the manufacturer's protective cover in place. Receiving, storage, and handling at the job site shall be in accordance with the requirements in ASTM D 4873 . 4 . SURFACE PREPARATION The surface on which the geotextile is to be placed shall be graded to the neat lines and grades as shown on the drawings. The surface shall be reasonably smooth and free of loose rock and clods, holes, depressions, projections, muddy conditions and standing or flowing water (unless otherwise specified in Section 7) . 5. PLACEMENT Prior to placement of the geotextile, the soil surface will be inspected for quality assurance of design and construction. The geotextile shall be placed on the approved prepared surface at the locations and in accordance with the details shown on the drawings and specified. The geotextile shall be unrolled along the placement area and loosely laid (not stretched) in such a manner that it will conform to the surface irregularities when material is placed on or against it. The geotextile may be folded and overlapped to permit proper placement in the designated area. SCS-NEH-20 95-1 8/91 A Method 1 The geotextile shall be joined by machine sewing erial meeting the chemical using thread of a mat geotextile fibers or yarn. The sewn requirements for the 11 overlap shall be 6 inches and the sewing of ahallrcoisist ofl 1 two parallel stitched rows at a spacing pp inch and shall not cross (except for any restitching) . The stitching shall be a lock-type stitch. Each row of stitching shall be located a minimum of 2 inches from the geotextile edge. The seam type and sewing machine to be used shall produce a seam strength, in the specified geotextile that, as a minimum, is 90 percent of the tensile strength in the weakest principal direction of the geotextile being used, when tested in accordance with ASTM D 4884 . The seams may be factory or field sewn. The geotextile shall be temporarily secured during placement of overlying materials to prevent slippage, folding, wrinkling, or other movement of the geotextile. Unless otherwise specified, methods of securing shall not cause punctures, tears or other openings to be formed in the geotextile. Method 2 The geotextile shall be joined by overlapping a minimum of 18 inches (unless otherwise specified) , and secured against the underlying foundation material. Securing pins, approved and provided by the geotextile manufacturer, shall be placed along the edge of the panel or roll material to adequately hold it in place during installation. Pins shall be steel or fiberglass formed as a "U" , "L" ,or. "T" shape or contain "ears" to prevent total penetration. Steel washers shall be provided on all but the "U" shaped pins. The upstream or up-slope geotextile shall overlap the abutting down-slope geotextile. At vertical laps, securing pins shall be inserted through both layers along a line through approximately the midpoint of the overlap. At horizontal laps and across slope laps, securing pins shall be inserted through the bottom layer only. Securing pins shall be placed along a line approximately 2 inches in from edge of the of the placed geotextile at intervals not to exceed 12 feet unless otherwise specified. Additional pins shall be installed as necessary and where appropriate,to prevent any undue slippage or movement of the geotextile. The use of securing pins will be held to the minimum necessary. Pins are to be left in place unless otherwise specified. I Should the geotextile be torn or punctured, or the overlaps or sewn joint disturbed, as evidenced by visible geotextile damage, subgrade pumping, intrusion, or grade I distortion, the backfill around the damaged or displaced area shall be removed and restored to the original approved condition. The repair shall consist of a patch of the same type of geotextile being used, overlaying the existing geotextile. When the geotextile seams are SCS-NEH-20 95-2 8/91 required to be sewed, the overlay patch shall extend a minimum of one foot beyond the edge of any damaged area and joined by sewing as required for the original geotextile except that the sewing shall be a minimum of 6 inches from the edge of the damaged geotextile. Geotextile panels joined fined b over J y la shall i P have the patch extend a minimum of 2 feet from the edge of any damaged area. Geotextile shall be placed in accordance with the following applicable specification according to the use indicated in Section 7: a. Slope Protection The geotextile shall not be placed until it can be anchored and protected with the specified covering within 48 hours or protected from exposure to ultraviolet light. In no case shall ' material be dropped on uncovered geotextile from a height greater than 3 feet. b. Subsurface Drains The geotextile shall not be placed until drainfill or other material can be used to cover it within the same working day. Drainfill material shall be placed in a manner that prevents damage to the geotextile. In no case shall material be .dropped on uncovered geotextile from a height greater than 5 feet. c. Road Stabilization The geotextile shall be unrolled in a direction parallel to the roadway centerline in a loose manner permitting it to conform to the surface irregularities when roadway fill material is placed on it. In no case shall material be dropped on uncovered geotextile from a height greater than 5 feet. Unless otherwise specified, the minimum overlap of geotextile panels joined without sewing shall be 24 inches. The geotextile may be temporarily secured with pins recommended or provided by the manufacturer but they shall be removed prior to placement of the permanent covering material. 6. MEASUREMENT AND PAYMENT Method 1 For items of work for which specific unit prices are established in the contract, the quantity of geotextile for each type placed within the specified limits will be determined to the nearest specified unit by measurements made of the covered surfaces only, disregarding that required for anchorage, seams, and overlaps. Payment will be made at the contract unit price. Such payment will constitute full compensation for the completion of the work. SCS-NEH-20 95-3 8/91 Method 2 For items of work for which specific unit prices are established in the contract, the quantity of geotextile for each type placed within the specified limits will be determined to the nearest specified unit by computing the area of the actual roll size, or partial roll size installed. The computed area will include the amount required for overlaps, seams,and anchorage as specified. Payment will be made at the contract unit price. ' Such payment will constitute full compensation for the completion of the work. Method 3 For items of work for which specific lump sum prices are established in the contract, the quantity of geotextile will not be measured for payment.

Two cross sections are also attached. I prepared these for Bryce Ecklein's use in discussing the channel work with Jim Green of the Corps. Since our federal sponsor for the East Side Green River Watershed Project cannot provide us with technical assistance in the time frame we need, I will be providing you a 1"=20' scale redline drawing (rather that AutoCad drawing) of the channel design for you to incorporate into the Oakesdale AutoCad drawings. I will also be preparing typical sections and a profile view of the channel. I intend to deliver the plan and section redline drawings to you on Monday next week, with the profile potentially being sent separately. Please call me at 277-5547 to discuss how the information on the channel design will be presented on the drawings. A separate bid schedule will need to be prepared for those items bid with the Oakesdale project that will be funded by the Surface Water Utility. At a minimum we intend to complete the trail realignment to SW 16th Street to accommodate the planned channel work. If we can obtain the necessary permits and sufficient funding, we will complete all of the channel widening work between Oakesdale and SW 16th Street under a separate bid schedule with the Oakesdale project. cc: Lin Wilson Barry Knight Ron Straka i�.
