The average discharge for two pumps pumping (which is a simulated situation for storm inflow) is 242 gallons Der minute. Honey Creek P.S. The knife Yates require 26 turns to travel from full open to full closed position. We performed tests for 3 to 4 foot drawdowns ranging from B-1/2 feet to 12 feet below top of floor. One test that had a drawdown of a little over 4 feet (13 feet below floor level ) was influenced by the concrete conical shaping. The measure- ment into the cone area was not used in computing flow rates. It is interesting that the second minute of each test normally has a higher pumping rate. I will review our design flow rate analysis with this information and pas., on comments regarding operation to you and Bob. Sincerely, HAMMOND, COLLIER & WADE - LIVINGSTONE ASSOCIATES, INC.

This review completed the study work analysis outlined in our letter proposal dated December 17, 1986. 0 Bob concurs with the recommendations ve made at the meetings and asked that we assist you with coordinating the scheduling and arrangements for work that should not be delayed. 0 Presented with this letter as Bob requested is a brief report of findings and recommendations for reinforcement of or stabilizing identified unstable areas together with an estimate of costs. o The prediction of when major movements could occur is not possible; there- fore, we have ta1•en the position that remedial work should proceed immedi- ately. We do know that the Coun,y side of the ravine which is a bit steeper in places has slipped and required temporary reinforcement work. o Bob emphasized that he wants us to pursue as aggressively as possible a schedule with which you are comfortable. RHErM ONATTLt ❑NEFATCM[ Mr. Richard C. Houghton January 14, IP87 Page Two Zone 1, the most uphill unstable area, repair can be accomplished now by use of a transverse trench drain buttress system. The proposed and most economical repair for Zone 2 is: a. To excavate and move the roadway prism downhill and compact material to provic not less than a 1 1/2 horizontal to 1 vertical slope. b. Replace the excavated prism with imported select fracture rock. Zone 3 needs correction but cra,.king has not yet developed. Near stream bank work requires fisheries approval. The problem at Zone 3 is extremely loose embankment coupled with stream erosion of the embankment toe. W^ are ready to assist you immediately. Pledse review the enclosed report and tail me on specific instructions. I will provide assistance on a priority emer- gency basis. � Thank you.

At your request, we have evaluated three slide zones on 127th Street in Renton to determine the cause of the sliding and develop recommendations for remedial work. Our evaluation included drilling one soil boring in each of the slide areas with a true: mounted drilling rig and performing hand probes at two of the slides. Logs of the truck bortngs are presented on Figures 7, 8, and 9. The results of our evaluation< and our recommendations are presented in the following: Slide M 1 , Station 10+00 The subsurface conditions and our recommended measures to improve stability are Illustrated on Figure 1 . Our explorations B-I and HP-1, indicate that the soils consist of loose silty sand overlying stiff silt, which in turn overlays very dense sand. Groundwater is perched atop the stiff silt, causing the lower portion of the loose sand layer to be saturated. T')e stability of the sand layer decreases as the ground water level increases, and failure has occurred during recent heavy rains To Increase the stability of this section of roadway, we recommend that finger drains be installed in the toe of the slope on approximately 12 foot centers. The finger drains should be installed by excavating trenches Perpendicular to the road along the top of the silt layer approximately as shown on Figure I . Slotted ADS pipe bedded in washed pea gravel should be plsced in the bottom of each trench and it shOUld be backfilled with compacted 2-inch minus crushed rock. The drains will lower the ground water level in the loose sand and the compacted crushed rock will serve as high shear strength buttresses, further increasing stability. SHANNON & WILSON. INC. i January 14, 198'i W-4689-01 Attn: Mr. Fred Kern Page 2 Slide 02, Station 7+25 The second slide appears to be the result of a very steep slope and very loose soils. The upper 20 feet of the road embankment slopes approximately 38 degrees to the horizontal, while the angle of internal frictfon of the soil appears to be about 30 degrees. The rather small amount of cohesion In these predominately granular soils has thus far prevented more extensive Sliding; however, additional sliding is very likely. Ground water was not encountered within the apparent slide mass, and does not appear to be a contributing factor to this slide. Our analysis Indicates three alternative means of increasing the stab1ity of the slope. These are Illustrated on Figures 2, 3 and 4, and are discussed below: •1 Fatten the slope by shifting the road and sewer pipeline to the south into the hillside and remove soil from the existing downslope shoulder of the road. This would entail excavation into the hillside and construction of a retaining structure such as the ecology block wall shown on Figure 2 or a soldier pile and lagging wall, to retain the cut. An ecology block wall will probably be less expensive, however, a soldier pile and lagging wall would OCCUPY less space, thereby minimizing the amount of excavation required. Soil removed from the hillside could b,; placed as fill to flatten the slope below the woad. A typical ecology block wall is illustrated on Figure 6. 02. Excavate the loose materials from the slide zone and replace them with densely compacted structural fill. This would require removal and replacement of most of the existing roadway to a depth of about 15 f-et in the slide area, including both utility pipelines. See Figure 3. The excavated material should be placed and compacted on the hillside to flatten it to 1 .5 horizontal to I vertical, as shown on Figure 3. 03. Flatten the slope by placing fill on the hillside below the road to achieve a 2 horizontal to i vertical slope. This alternative is illustrated on Figure 4. Preliminary calculations Indicate that about 50 cubic vards of fill per foot of road way would be required to achieve this slope. Slide 03 The area we have Identified as Slidc 03 has yet to fail, however, its failure is Inevitable if remedial measures are not Implemented. At this location the creek actively erodes the toe of the slope during periods of high flew, causing it to be oversteepened. The existing conditions are .�Ilistrated on Figure 5. SHANNON Q WILSON. INC. i P e January 14, 1987 W-4669-01 Attn: Mr. Fred Kern Page 3 In our opinion this section of roadway should be protected by the placement of a buttressing fill to flatten the already oversteepened area and a rip rap lanket to pr evont further erosion. These recommendation are illustrated on Figure S. For any of the above stabflization schemes, stripping of the existing organics and the placement of a freely draining blanket of sand and gravel will be required prior to placement and compaction of fill on the hillside. In the case of slide 113, the crushed rock wouid be sufficifmly permeable to serve as a drainage blanket. All fill should be placed in approximately horizontal lifts and compacted to at least 92 percent of ;is Modified Proctor maximum dry density. We appreciate the opportunity to be of service.

Y TABLE OF CONTENTS I. Report by Shannon & Nilson with Figures and Preliminary Analysis (Draft) 2. Summary of Repairs and Budget Estimates for Repairs SUMMARY OF REPAIRS AND BUDGET ESTIMATES FOR REPAIRS Basis of Budget Estimates: Based on Shannon & Wilson's recommendations for repairs (and a crn,s section at each area) , we have completed analysis of costs and other detail described below. Drawings of the repair areas are enclosed as 1" = 40' scale reduced plans and 1" = 20' scale reduced profiles (Figures 1 , 2, 3 and 4). The refer- enced station numbers used below are consistent with those detailed in Shannon 8 Wilson's report. Actual subsurface conditions may vary from the generalized detail determined from the bore pits. Therefore, the quantities and resultant budget estimate computations should be reviewed as probable. Changed subsurface conditions could change actual quantities used, removed, etc. Force Account: Due to the urgent nature of making emergency repairs , a -odified force account contracting procedure is recommended. We have ins a nominal allowance for preparing a modified force account agreement with the contractor selected to complete repair work. The contractor selected should have a good familiarity with the site(s) and be a contractor who has demonstrated competence on similar modified force account work. Instructions to the Contractor: Construction period forces (i.e. , heavily loaded trucks, vibratory compaction) all need to be considered as repairs are made. Truck routing, loading, dumping are all items that will be addressed by the consultant in monitoring repair work to reduce disruption of adjacent areas. Although there is no assurance that adjacent area slumps will not be induced, we believe with proper care adjacent areas can be protected and maintained stable. The consultant can make no warranty that additional slippage or slides will not develop. However, it appears that correction of the three areas identified is a reasonable slope improvement program. Permits for Downhill Embankment Construction: Fisheries Department officials should be advised of construction plans even though in-creek work is not planned. The downhill embankment slope catch points for the proposed repair work are beyond the existing right-of-way boundaries. If slope easements are not a part of the road ownership documents, pe—its for embankment modification should be addressed. The downhill property for oume of the force main route is apparently in County ownership. All property ownership in the new embankment area should be confirmed and appropriate agreements, easements, etc. , arranged before construction repairs commence. Slide No, 1, Station 10+00 (10+09): Water is the driving force in movement in this area. The procedure recommended is to excavate with backhoe bucket transverse to the slope and progressively use this procedure in about six locations. Our budge* estimate for repair of the 10+09 slip area does not include rr,n - struction or relocation of the existing f rce main. Budget Estimate Slide No. 1 Repair: Force Account Contract Document S 500.00 Survey Layout 500.00 Construction with Sales Tax 12,600.00 Monitoring, Time & Quantity Verification $ 1,�600 00 Total Probable Schedule Time for Repair = 3 Days. Slide No. 2, 7+25 (7+19): Too steep a slope related to embankment strength is the driving force in move- ment for Slide No. 2. Water- occurs higher up at a seepage outcropping in the cut slope. Water seepage is a factor in surface slumping which periodically occurs above the road; however, water does not appear to contribute to the present instability of the roadbed at this site. Shannon & Wilson provided three alternative correction measures (1, 2 and 3) i _r Slide No. 2. All alternatives involve relocating or rebuilding a segment of the force main. Alternative No. 2 would also involve reconstructing a segment of the water main. Slide No. 2, Alternative No. 1, would have greater benefit if additional right- of-way could be secured and the reverse roadway curve eliminated. Figures 1 and 2 illustrate the alignment improvement which would be achieved by containing a soldier pile - ecology wall system within the right-of-way.

Flattening and heavy rocking of this area is recommended. Because of close proximity of the slope toe to the creek, a fisheries permit for near stream improvements should be discussed with Fisheries Department representatives.

This review completed the study work analysis outlined in our letter proposal dated December 17, 1986. o Bob concurs with he recommendations we made at the meetings and asked that we assist you with coordinating the scheduling and arrangements for work that should not be delayed. o Presented with this letter as Bob requested is a brief report of findings and recommendations for reinforcement of or stabilizing identified unstable areas together with an estimate of costs. o The prediction of when major movements could occur is not possible; there- fore, we have taken the position that remedial work should proceed immedi- ately. We do know that the County side of the ravine which is a bit steeper in places has slipped and required temporary reinforcement work. o Bob emphasized that he wants us to pursue as aggressively as possible a schedule with which you are comfortable. REPIr TO 0SEAM9 pWENATCNU Mr. Richard C. Houghton January 14, 1987 Page Two Zone 1, the most uphill unstable area, repair can be accomplished now by uti2 of a transverse trench drain buttress system. The proposed and most economical repair for Zone 2 is: a. To excavate and move the roadway prism downhill and compact material to provide not less than a 1 1/2 horizontal to 1 vertical slope. b. Replace the excavated prism with imported select fracture rock. Zone 3 needs correction but cracking has not yet developed. Near stream bank work requires fisheries approval . The problem at Zone 3 is extremely loose embankment coupled with stream erosion of the embankment toe. We are ready to assist you immediately. Please review the enclosed report and call me on specific instructions. I will provide assistance on a priority emer- gency basis. Thank you.

At your request, we have evaluated three slide zones on t27th Street in Renton to determine the cause of the sliding and develop recommendations for remedial work. r Ou evaluation included drilling one soil boring in each of the slide areas with a truck mounted drilling rig and performing hand probes at two of the slides. Logs of the truck borings are presented on Figures 7, 8, and 9. The results of our evaluations and our recommendations are presented in the following: Slioe III , Station 10+00 The subsurface conditions end ou.- re,.ommended measures to improve stability are illustrated on Figure I. Our ernlorations 8-1 and HP-I , Indicate that the soils consist of loose salty sand overlying stiff silt, which in turn overlays very dense sand. Groundwater is perched atop the stiff silt, causing the lower portion of the loose sand layer to be saturated. The stability of the sand layer decreases as the ground water level increases, and failure nas occurred during recent heavy rains. To Increase the stability of this section of roadway, we rec,)mmend that finger drains be installed in the toe of the slope on approximately 12 foot centers. The finger drains should be insk. ..ed by excavating trenches perpendicular to the road along the top of the silt layer approximately as shown on Figure 1 . Slotted ADS pipe bedded in washed pea gravel should be placed in the bottom of each trench and it should be backfilled )with compacted 2-inch minus crushed rock. The drains will lower the grounwater level in the loose sand and the compacted crushed rock will serve as high shear strength buttresses, further increasing stability. SHANNON a WILSON. INC. W-4689-01 January 14, 1987 Attn: Mr. Fred Kern Page 2 Slide 02, Station 7+25 The second slide appears to be the result of a very steep slope and very loose soils. The upper 20 feet of the road embankment slopes approximately 38 degrees to the horizontal, while the angle of internal friction of the soil appears to be about 30 degrees. The rather small amount of cohesion in these predominately granular soils has thus far prevented more extensive slldino; however, additionr.l sliding is very likely. Ground water was not encountered within the apparent slide mass, and does not appear to be a contributing factor to this slide. Our analysis indicates three alternative means of increasing the stability of the slope. These are Illustrated on Figures 2, 3 and 4, and are discussed below: 01 . Flatten the slope by shifting the road and sewer pipeline to the south into the hillside and remove soil from the existing downslope shoulder of the road. This would entail excavation into the hillside and consti n of a retaining structure such as the ecologv block wall shown on Figs a soldier pile and lagging wall, to retain the cut. An ecology block w( ill probably be less expensive, however, a soldier pile and lagging wall would occupy less space, thereby minimizing the amount of excavation required. Soil removed from the hillside ^ould be placed as fill to flatten the slope below the road. A typical ecology block wall is illustrated on Figure 6. 112. Excavate the loose materials from the slide zone and replace them with densely compacted structural fill. This would require removal and replacement of most of the existing roadway to a depth of about 15 feet in the slide area, including both utility pipelines. See Figure 3 The excavated material should be placed and compacted on the hillside to flatten it to 1 .5 horizontal to I vertical, as shown on Figure 3. 03, Flatten the slope by placing fill on the hillside below the road to achieve a 2 horizontal to I vertical slope. This alternative is illustrated on Figure 4. Preliminary calculations Indicate that about 50 cubic yards of fill per foot of road way would be required to achieve this slope. Slide 03 The area we have identified as Slide 03 has yet to fail, however, its failure is Inevitable if remedial measures are not Implemented. At this location the creek actively erodes the toe of the slope during periods of high flow, causing it to be oversteepened. The existing conditions are illustrated an Figure 5. SHANNON at WILSON. INC. i F January 14, 1987 W-4689-01 Attn: Mr. Fred Kern Page 3 In our opinion this section of roadway should be protected by the placement of a buttressing fill to flatten the already oversteepened area and a rip rap blanket to prevent further erosion. These recommendation are illustrated on Figure 5. For any of the above stabilization schemes, stopping of the existing organics and the placement of a freely draining blanket of sand and gravel will be required prior to placement and compaction of fill on the hillside. In the case of slide 03, the crushed rock would be sufficiently permeable to serve as a drainage blanket. All fill should be placed in approximately horizontal Ilfts and compacted to at least 92 percent of its Modified Proctor maximum dry density. npreciate the opportunity to be of service.

Summary of Repairs and Budget Estimates for Repairs SUMMARY OF REPAIRS AND BUDGET ESTIMATES FOR REPAIRS Basis of Budget Estimates: Based on Shannon & Wilson's recommendations for repairs (and a cross section at each area) , we have completed analysis of costs and other detail described below, Drawings of the repair areas are enclosed as 1" = 40' scale reduced plans and 1" = 20' scale reduced profiles (Figures 1 , 2, ind 4). The refer- enced station numbers used below are consistent with those detailed in Shannon & Wilson's report. Act i subsurface conditions may vary from the generalized detail determined from the bore pits. Therefore, the quantities and resultant budget estimate computations should be reviewed as probable. Changed subsurface conditions could change actual quantities used, removed, etc. Force Account: Due to the urgent nature of making emergency repairs, a modified force account contracting procedure is recommended. We have ine,uded a nominal allowance for preparing a modified force account agreement with the contractor selected to complete repair work. The contractor selected should have a good familiarity with the site(s) and oe a contracto, who has demonstrated competence on similar modified force account work. Instructions to the Contractor: Construction period forces (i.e. , heavily leaded trucks, vibratory compaction) all need to be considered as repairs are made. Truck routing, loading, dumping are all items that will be addressed by the consultant in monitoring repair work to reduce disruption of adjacent areas. Although there is no assurance that adjacent area slumps will not be inducea, we believe with proper care adjacent areas can be protected and maintained stable. The consultant can make no warranty tha additional slippage or slides will not develop. However, it appears that correction of the three areas identified is a reasonable slope improvement program. Permits for Downhill Embankment Construction: Fisheries Department officials shou',d be advised of construction plans even though in-creek we ,k is not planned. The downhill e,.;bankment slope catch points for the propose epair work are beyond the existing right-of-way boundaries. If slope easei,,.ots are not a wart of the road ownership documents, permits for embankment modification shoula be addressed. The downhill property for some of the force main route is apparently in County ownership. All property ownership in the new em4ankment area should be confirmed and appropriate agreements, easements, etc. , arranged before construction repairs commence. Slide No. 1, Station 10+00 10+09 : Water is the driving force in movement in this area. The procedure recommended is to excavate with backhoe bucket transverse to the slope and progressively use this procedure in about six locations. Our budget estimate for repair of the 10+09 slip area does not include recon- struction or relocation of the existing force main. Budget Estimate Slide .No. 1 Repair: Force Account Contract Document $ 500.00 Survey Layout 500.00 Construction with Sales Tax 12,600.00 Monitoring, Time & Quantity verification 1,60O�Ob Total li Probable Schedule Time for Repair = 3 Days. Slide No. 2, 7+25 (7+19): Too steep a slope related to embankment strength is the driving force in move- ment for Slide No. 2. Water occurs higher up at a seepage outcropping in the cut slope. Water seepage is a factor in surface slump'lg which periodically occurs above the road; however, water does not appear to contribute to the present instability of the roadbed at this site. Shannon & Wilson provided three alternative correction measures (1, L and 3) for Slide No. 2. All alternative involve relocating or rebuilding a segment of the force main. Alternative No. 2 would also involve reconstructing a segment of the water main. Slide No. 2, Alternative No. 1, would have greater benefit if additional right- of-way could be secured and the reverse roadway curve eliminated. Figures 1 and 2 illustrate the alignment improvement which would be achieved by containing a soldier pile - ecology wall system within the right-of•way.

O Probable Schedule Time for Repair = 7 Days. Slide No. 3 (1+97): Creek erosi at the toe of a too steep slope will progressively erode and jeopardize �lcpe stability. Flattening and heavy rocking of this area is recommended. Because of close proximity of the slope toe to the creek, a fisheries permit for near stream improvem-nts shoul, :',e discussed with Fisheries Department representatives.

City of Renton 200 ti,I I Aver .c South Renton, Washill9ton 980 E Re: Honey Creek N.E. 27th Street Slumping Study Proposal Dear Bob: As discussed, here is our proposal to perform the detailed field investigation and prepare the conceptual design for remedial work in the three areas that show evidence of slope instability. Background: Bill Laprade of Shannon and Wilson and I walked the pressure sewer route and measured the surfic.ial extent of slope instability zones on Monday, December 15, 1986. There i! evidence of slope instability at three locations along N.E. 27th. Similar scarps in the county road areas are evident on the opposite side of the ravine (120th Place S.E. ). One of these scarp zones apparently failed The county has reconstructed the roaa embankment utilizing gabion baskets. The visual pavement distress area (cracking zones) on N.E. 27th intersect the horizontal location of the pressure sewer. Based on recent experience on the county portion of the road, ultimate slippage failure and pipeline damage should be anticipated on N.E. 27th. In order to develop an engineered remedial solution, the depth and slope of the slide zone need to be determined by drilling. There is some evidence of water seepage springs downhill of one of the unstable areas. A good uphill ditch flow was apparent near another unstable area. These water sources need to be located. P86082 REPLYTO ❑WTTLE LYWENATCHEE Mr. Robert E. Bergstrom, P.E. December 17, 1986 Page Two As a result of this preliminary investigation, we have prepared the attached Scope of Work Budget Estimate and Project Authorization form. We have based the budget estimate on study of three specific areas exhibiting distress. If unusual or unanticipated circumstances are discovered during the course of the field observations, a scope modification may be appropriate. However, we are not aware of any specific unusual circumstances and we will not exceed the budget detailed above without further authorization by the City of Renton. Bill Laprade advises he has a drill truck arranged for Monday, December 22, 1986, He will be prepared to start the field reconnaissance on Friday, December 19th. The drill truck length will require blocking off 27th N.E. to through-traffic. During drilling, the truck could be moved for an emergency event only. Our surveyors are also set to start cross-sections on Monday December 22, 1986, and pick up specific detail that Bill Laprade requests. It all detail is in order will you start the arrangement to shut down 27th N.E. on Monday; the drill truck is scheduled to arrive about 8:00 a.m. and we plan one day of drilling. We plan to complete the analysis and discuss results with y oefore the year-end. We are transmitting two copies of this letter with attachments and our standard Project Authorization form.

We will next plot the survey and soils information, including locations of uphill/downhill springs that are detected, to provide a good picture of conditions at each unstable roadway area. 5. With plots and information compiled, we will review data and with Shannon and Wilson prepare sketches of several alternative methods of slope stabilization with an index of cost for each. With these worksheets, we will meet with you or designated staff and review our analysis.

Should one pump fail to operate, the other will be activated. The sequential operation of the pumps is discussed in greater detail in the Pump level Controls Section. The pumps have been provided with carbon-ceramic mechanical seals, which are to be water lubricated (from protected potable supply). Either pump can be removed for inspection or service by means of a trolley and chain hoist, with crane rail and supports, which is provided in the enclosure. The local supplier of the Clow Yeomans pumps is N.O. Fowler Com- pany; 13440 SE 30th Street; P.O. Box 160; Bellevue, WA 98009; telephone (206) 746-8400. The vertical pumps are enclosed in a prefabricated reinforced fiberglass pump house which sits directly above a 96" diameter wet well . Each pump has a 4" ductile iron suction intake line 15'-4" long, which extends from 8" above the floor of the wet well . From the 4" pump dis- charge, the sewage line is increased to 6", then passes through a wafer check valve designed to reduce operational fouling. This is followed in turn by a 6" knife gate which permits a defined "Y" orifice flow con- trol . The two discharge links meet in a wye with an increaser adaptor connecting to the 8" ductile iron force main. At any time, either pump may be taken out of service for maintenance operation by isolating the line at the knife gate (i .e. closing it) and adjusting the alternator to utilize a one pump mode. Note all maintenance operations on pumps should be preceded by electrical pump operation lockout to avoid accidental start-up during maintenance. A specific checkout procedure based on experience at other stations of the same type is recommended. The pump motor and top housing can be removed for access to the impeller volute. When the housing is reassembled, all elements must be tightly secured and gasketed to assure vacuum units will not draw air. The motors are equipped with eye bolts which are diagonally situated on the top of the motor. To avoid torsion or eccentric loading when (13) lifting, insert a solid steel shaft that will just pass through the lifting eyes. Each end of the bar should be threaded such that nuts can be placed on each end of the rod to avoid accidental rod slippage. The lifting shaft is used to avoid weak direction lateral loading cf the eye bolts. See sketch below. memo` e ONE )mYEt�LT (�►2).

Don Holt says Lakeside iydustries (Washington Asphalt) insists on waiting until weather :s warmer (45D minimum with temperature rising). In my mind, I completely agree that overlaying Lake Washingto)) Blvd. should be done during optimum warm weather for good adhesion; however, the ?8th Place paving is much less sensitive to temperature deficiency. Don, says he'll pave, but he wants a release to order pavers in. Bt-ause of holiday shutdown, paving will not start before January 5, 1986 in any event. In the meantime, I 'vc asked Dun to find out what additional mob lization costs would be encountered if we were to do Lake Washington B1 )d. and 28th Place separately. You and I can then better make a decision on various paving alternatives. Sincerely, -fie C Frederick G. Kern, P.E.

Relocating requires access to the camera at these intervals along the line. The access must be much iarger than the cleanouts on this project, as the camera will not fit through them. Therefore, if TV monitoring is felt required, it would require the cutting of the line every 450 LF which would be 12 cuts. At each cut a 4 or 5 foot section of pipe would have to be removed and then replaced, and fastened back with 2 each Romac type couplings. It shnuld also be considered that 4 of these cuts would have to be made in the upper regior, in the creek itself. The cuts and Romac couplings in the pipeline would do much to diminish the integrity of the line as it was constructed. As it is now, this line is maintenance free as It is one entire unit, every joint either being shackled, flanged or fused. This many Romac type joints should be unacceptable. When receiving bids for this item, it was assumed there was no limit on the camera's range or need for access as none was ever brought to our attention by the specs or by the firms quoting the work. It was onl)Afterward, in subsequent conversations with the camera people that it became evident they were no more aware of the unique properties '•J� of this project from use of the poly pipe in curvlinear fashion any lIT' more than we were aware there were restrictions on their abilities. 1 In talking to these people, it almost seems as though a TV monitor (J does not lend itself to this project. The line has passed a 40 PSI for 6 hours test for air tightness and could have gone longer, have flaked to Jerry of Precision Sealing, Gary Vasey of Gary's Telescan and Jim of A & R Eductor services All do this camera work and all are of the same opinion_ My personal feeling is that since CONTRACTORS LICENSE NUMBER RL AL-1-262KP page 2 the line tests, there should be no need for visual inspection at expense of cutting the line. A thought would be to video the top and bottom 400 LF of the line. Please review and advise. Thank you, R L All ny - � r Richard L a, President °1 HAMMOND,COLLIER&WADE - LIVINGSTONE ASSOCIATES. INC.

Warren, City Attorney AE: Professional Services Contract Amendment µ4 Honey Creek Sanitary Sewer Dear Bob: The contract amendment is approved as to legal form with two concerns. The first concern is that I have no way of gauging the reasonableness of the expense of nearly $26,000 .00 to monitor construction, diary events and record material quantities and suryeyors to stake work . I presume that the Engineering staff feels that figure is accurate . My real concern is the breakdown of the budget by month which indicates that $6 , 500 .00 of the budget. was to be expended in August and $10, 300 .00 in September . We are nearly through with September and nearly 75% of the amount to be paid under this contract amendment will have already been expended. It _j2oks_to me like this contract amendment �gg;te late. If thegg_.Expenditures were not authorized in the riginal contract, then I presume that somebody on the City staff authorized the expenditures. If those expenditures were aut orized, I presume the amounts were ir,clude 1 budget . If these statements are not correct, then a royal for the new expenditures should have been obcair�g e the work began. Preparing con-.racts for work that has large y been done distorts the normal balance of power between the Executive and Legislative branches of government. While I am sure that there is nothing exceptional in this contract, the timing does raise concerns. Lawrence J.

Pankiewicz Re: Honey Creek Phase II Your Letter of August 28, 1985 Dear Gary: Thank you for providing cost detail on the upsizing of subdrain from 4" to 8" size. The upsizing was determined reasonable because of several factors after consultation with the firm of Shannon & Wilson. Your cost figures including excess rock were just under $3,600 for the 1210 lineal feet (roughly $3.00 per foot). I have therefore advised Jim Chatterbon that all the subdrain would be paid for on the basis of the $6.00 bid plus $3.00 per lineal foot for upsizing. To keep everything simple we'll just multiply the actual footage by 1.5 to account for upsizing and leave the bid price constant. Sincerely, Frederick G. Kern, P.E.

The pump station finish up work could proceed now; however, because Of the staging area for Phase II wrrk it would be better to wait until R. L. Alia Company completes the curved pipeline and road-construction. 2. If favorable weather continues it appears that the creek restoration roadwo-k and services will be finished by the end of August. 3. Easement finalization for the electrical service schedule D work needs finalization. Schedule D work should also logically be finished before the pump station is finished to reduce dust damage to electrical pump station equipment. 4. The fisheries would like to see the removal of the 54 inch culvert east cf the pump station; and, with relocation of the pump station, the culvert could be removed. 5. Ron Scott and Tom Kivley have been most helpful in staying clear of the operation for the last month; but, in fairness to their finishing work in good weather too, we should collectively coordinate a finish-up program that favors everyone. 6.

Note the project has an access road along most of the route to permit City crews a route to maintain the pipe and streambed. The pipe will most likely be polyethylene but the contractor has not yet confirmed ti s. I would appreciate your comments on: 1 ) A maintenance- procedure recommendation for the City. (Note the minimum Radius on the 12" pipe is in the range of 50-60 feet) The claaning concept we f discussed is to clean the entire 5000+ feet of curved sewer in one pigging operation. 2) Specific type of pig recommended for routine maintenance. 3) Type of pig and procedure to knock off the fusion rings assuming poly fusion process is used. (I had not included this as a requirement in the specifications. ) 4) Uoes the direction of the cleanout present a potential problem. We do not want to get a unit stuck and not be able to dislodge it. I will relay your cow nents c -) the City with our recommendations or maintenance techniques, The —k bidder on the Phase 2 Pipeline work is R.L. Alia Company of Seattle. The construction work in the creek is scheduled to begin about Thank you for your assistance. rze Sincerely, W8-109 Frederick G. Kern, P.E.

Hammond, Collier & Wade - Livingstone Assoc. , Inc. 4010 Stone Way North Seattle, Washington 98103-8090 Dear Mr. Kern: Thank you for the drawings and specifications ft. r the Reuton- Honey Creek Sewer Project. We will attempt to answer your q�restions in the order you pre- sented them. i:lA. The maintenance procedure should be set so that as the , ,;.ping pressure increases , say 5 P.S. I . , then a pig is rui. provided the pipeline is a full flow system. This will remove the deposits before they have an opportunity to set up ha ' Usually one pig run is sufficient to keep the pipe clean. #1B. If the system is more gravity flow rather than a pressure system, as most new force mains are, then the routine pigging should be set up on a calendar schedule, i.e. , once a week, once a month, etc. The rapidity of buildup will help in the establishment of this routine. This type of line is usually the one that requires the most attention because low flow sol;,'s will drop out much faster; but until maximum capacitl- is needed, tt,e problem does not show up. #2. Pecause of the smooth inter-' or surface of the polyethylene pipe, our Aqua Bare pigs or Aqua Crisscross pigs are all that are needed. You are wise to choose cleaning tt.e entire length at one time. !a not break the line up into shorter lengths for maintenance cleaning . Most lines such as this are 3 to 10 miles long - all m ,r . ed clean with one pig run the total length. Plants in USA. Canada,Japan, Holland and South Africa page 2 Mr. Frederick G. Kern, P.E. June 21, 1985 � #3. We are glad you proposed the idea of removal of fusion rings prior to canstruction. Our suggest-ion is to install an ACC-T in the first joint of pipe laid and then lay 5 or 6 joints. Then 11s4_ng air pressure, shoot the pig through this section, count the rings , and if all have been collected, insert pig again and continue laying 5 or 6 more joints . Repeat the process. Of course, after about 2500 ' , you will probably want to begin anew and then fuse join the center section as the final connec- tion. Make one last pig run f-om beginning to end. Should you wait until the line is complete to attempt removing the rings , then the task may be too :such for a pig and plug the line. #4. The direction of the clean out does not present a problem. We would suggost, however, that should you wish to launch through one of the clean outs, that it be turned in the reverse direction.

Each pipeline is approximately 18.5 miles in length . The pipe)i.nes were constructed of plastic lined carbon steel. :n each pipeline, there were eighteen 10" DeZurick plug valves that the pigs had to pass through. We initially attempted piuying with sludge, but due to low volwne available (50 -- 306 GPM, 140 PSI) , we were unable to successfully pig through the plug valves . However, by rearranging the valving at the pump station, we could deliver 1200 GPm of non-potable water (@ 50 PSI) into ,ither line. This proved to be more than enough flow to nut the Aqua Swab, Aqua Fare, and Aqua Criss Cross type pigs we used. Each pig ran with no problems and came in on schedule. For future reference, however, we attempted to run an Aqua Criss Cross pig with the Heath transmitter . This pia lodged in the "irst plug valve it entered. Even with 1200 GPM, this pig would not pass through the plug valve. We backed out th= pig and noted the transmitter cavity was damaged. There- fore, ue would recommend that transmitter pigs not be used when trying to pig through 10" or smaller DeZurick plug valves . Very truly yours, 1 V� Spencer Cubage, Mgt.

Existing Situation Seasonal sewage flows contributory to the Sunset Bills Pump Station (No.2) exceed the capacity of the pump station; and, excess pump station in'low overflows into Honey Creek. There is also another emergency overflow from the Honey Creek Pump Station No. I into Honey Creek. II. Improvements Program Scope An interceptor sewer down Honey Creek is planned to capture Sunset Pimp Station 02 overflows and permanently collect sewage from the oney Creek Pum Station Pio. 1. The Hone Creek Pum Station No. I which present y serves some Tresidences wi e a ando%n . The route of the interceptor traverses a short section of Union Street from the existing Sunset Pump Station vicinity north to Honey Creek. The sewer location continues down Honey Creek to a ne•- pump facility at Devils Elbow (Hereinafter referred to as the Devils Elbow Pump Station) . Several properties :n the Honey Creek water shed will have connections into the interceptor. The interceptor can eventually be extended downstream (beyond the Devils Elbow Pump Station) if a future Metro May Creek interceptor is construc+ed. The Devils Elbow Pump Station will lift sewage up to existing gravity sewer west of Edmonds Avenue in NE 27th Street. Certain sectors of the existing downstr �im gravity sewer are design capacity deficient. Introduction of additional sewage diverted from Honey Creek and Sunset Pump Stations I and 2 requires replacement of design capacity deficient sewer segments. Replacement of other sectors will increase the capability of the existing system to accept future design flow from both Honey Creek diversion and additional Kennydalc vicinity growth Flows in the existing sewer both diversion and existing contribution are to be monitored by flow measurement at selected manholes. The Devils Elbow Pump Station will be equipped with special variable orifice type knife gate to permit diversion flow modulation. The modulating operation and system setting will be described in the Devils Elbow Pump Station operations manual . ill. Design Criteria Each of the project elements has multiple benefit. That is in addition to providing relief of the intolerable sewage overflow into Honey Creek the features have long term benefit potential . The design criteria has there- fore been established to satisfy several condi ,ions for each element . Interceptor Sewer Criteria The interceptor route is principally located in steep terrain Honey Creek Watershed. The interceptor pipe slope provides excellent velocity and capacity potential . III Design Criteria (Cont'd) Two principal criteria were considered in evaluating the design require- ments: o The interceptor sewer must be of sufficient size to accommodate full time diversion of Honey Creek Pump Station No. 1 inflow plus overflow sewage that Sunset Pump Station No. 2 cannot pump during peak inflow infiltration wet season occurrences. Due to higher power consumption costs for the new Devils Elbow diversion pumping system, the Sunset Pump Station is to be maintained and kept in continuous operation. The high lift Devils Elbow Pump Station requires more power per unit ^f sewage to pump than does the Sunset system; so, the inflow to the Devils Elbow Pump Station will be regulated. To maintain a modest continuous flow in upper reaches of the interceptor, a portion of the gravity system in Union Street will be diverted directly to the interceptor at Phase 2 Mdnhole No. 3. o The interceptor sewer must also be capable of accommodating the full service area flow from the Sunset Pump Station contributory area. Sewers in this area are being upgraded by grouting operations; and, thus some flow reductions due to I and I correction are probable. Devils Elbow Pump Station and Pressure Sewer Criteria The pump station must have sufficient storage capacity to permit pumping modulation. Peak pump discharge must be regulated such that existing downstream sewer capacity (as improved) is not exceeded. Flow rate in the 8 inch pressure discharge line should not be less than 2 fps. A velocity of 2 fps translates to a flow rate of roughly 350 gpm in the 8" pressure sewer, Downstream Existing Sewer Rebuild and Replacement The existing capacities of various sectors of downstream gravity sewers were calculated based on .013 "n" values as required by Washirgton State Depart- ment of Ecology. Existing and near term Kennydale area flow quantities were estimated and subtracted from the calculated capacities to obtain residual capacity. The amount of inflow infiltration into the existing downstream collection system (West of Edmonds) is not known; and, estimates based on "Metro" I and I criteria are noted in the analysis support detail . Monitoring flow is an integral part of the program operation. By monitoring existing system flow, the Devils Elbow Pump station and or other pump stations can be "pinched" down to keep total flows restricted to the pipeline design capacities. Two principle criteria on upsizing were established: 1. Sewer upsizing should be completed to accommodate a Honey Creek diversion. The diversion flow rate should not be less than that required to maintain adequate new force main velocities. 2.. Sewer upsizing should be such that any such upsizing will satisfy ultimate Kennydale development d0f/3 iV. Design Analysis Summary Phase 2 Construction (Interceptor) A brief analysis of the interceptor sewer is presented in the Referendum 39 December 19E2 Grant Application. Flow calculations noted in the application are: Interim: A portion of sewage that currently overtaxes the Sunset Pump tat on will be routed to the Devils Elbow Pump Station. This peak overflow is conservatively estimated at ; ;0 gpm, An 3 inch sewer at the general stream gradient slope is in the range of 2.4 c.f.s. or 1075 gpm. Thus an 8 inch size would be sufficient to handle the total existing high infiltration over flow rate. Future Sunset Hills and Honey Creek basin area future sewage flow for full development is estimated in the grant application to be 2200 gpm peak or 4,9 cfs, 10 and 12 inch sewer sizes at stream gradient slope will carry respectively 4.4 and 7.1 cfs respectively. I & I grouting work on the area contributory to the Sunset Pump Station is planned; and, peak flow rate reduction will result. The design of the interceptor should most logically be based on not less than 10 inch size. 4-am/3 CITY OF RCNTON HONE1' CREEK INTERCEPTOR REF. 39 GRANT APPLICATION DECEMBER 1982 GENERAL DESCRIPTION OF PROJECT Construction of approximately 5,300 L. F. of the Honey Creek Interceptor, together with an interim sewage lift station and downstream gravity line improvements. The goal of the proJ.ct is to eliminate 4 to 5 sewage overflows Per year at the Sunset Lift Station, and to eliminate one additional small lift station (see attached map) . PROJECT ELEMENTS 1 . 5,300 L.F. of 12" gravity sewer line connecting the existing Sunset Lift Station to a new interim lift station. The Sunset Lift Station curr'ntly has a capacity in excess if 50U 9.p.m. which will remain. It is intended that overflows beyond 500 9.p,m, will dis-harge into the Honey Creek Interceptor. 2. Interim lift station - the capacity of this facility will be 450 9-p.m. and will lift overflows from the existing Sunset Lift Station to an existing gravity sewer line through 2,300 L. F. of 6" diameter force main. 3. Downstream gravity sewer improvements - approximately 1 ,550 L. F. of 8" gravity sewer line at minimum slopes will be upgraded to 121, diameter to Provide capacity for both existing connections as well as anticipated flows from the interim lift station, FLOW CALCULATIONS I .

Shannon & Wilson have been retained to provide construction period advice on all areas of Honey Creek where roadway or pipeline excavation will be made. Mr. Bill La Prade is providing specific advice on steep sewer area. There are other nearly identical locations where smaller 6" service sewers traverse equally steep bank. To our knowledge potential soil slides are of a surficial nature in the Honey Creek area. Deep seated slides are not anticipated. In any event there is no alternative method to satisfy elimination of overflow except to cDnstruct sewer down the bank; and,we will make sure the steep pipe is properly constructed. 2. The N.E. 17th Place diversion represents a very small flow contribution from approximately 17 homes. The peak flow rate from N.E. 17th Place would be in the range of 5 gallons per minute or less. Five gallon: per minute flow rate is roughly 1% of the new Devils Elbow pump station pumping capacity. n[rEr To ❑sur•Lc U w[N+rcrEc Mr. Chris A. Haynes, P.E. , Supervisor May 31, 1985 Page 2 3. Addendum N1 to the Phase 2 bid documents included required detail . 4. Mr. Joe Robel advised the low bidder on May 29 that construction could begin in June. I have requested,to Mr. Robel , that he issue a permit to the City for the Phase 2 work. We will send a copy when same is in hand. 5. The pavement patching is to be completed only to the depth required to match existing pavement structure. We recognize that DOE is net committed to and will not participate in grant funds for improving the roadway. 6. Washington Fisheries requested that the willow starts be generously matted in locations. Root intrusion should not be a problem; the pipe will be an impervious continuous fuse welded polyethylene pipe. Bob Bergstrom has been handling the Honey Creek emergency power for the pump station; and, he will separately respond to this natter. The State Fisheries Department has advised R. L. Alia Company that the July 22 date can be moved up to this date (June); so, we are most anxious to get r the award made and allow the contractor as much good skmmer weather work period as possible. Please advise us as soon as the Phase II work can he awarded. A preconstruction conference for Phase II work is scheduled for 10:00 a.m. June 12, 1985 at the 4th Floor Conference Room, Renton Municipal Building. Thank you for your assistance.

Note the project has an access road along most of the route to permit City crews a route to maintain the pipe and stre3mbed. The pipe will most likely be polyethylene but the contractor has not yet confirmed this. I would appreciate your comments on: 1) A maintenance procedure recommendation for the City. (Note the minimum radius on the 12" pipe is in the range of 50-60 feet) The cleaning concept we discussed is to clean the entire 5000+ feet of curved sewer in one pigging operation. 2) Specific type of pig recommended for routine maintenance. 3) Type of pig and procedure to knock off the fusion rings assuming poly fusion process is used. (1 had not included this as a requirement in the specifications. ) 4) Does the direction of the cleanout present a potential problem. We do not want to get a unit stuck and not be able to dislodge it. I will relay your comments on to the City with our recommendations on maintenance techniques. The low bidder on the Phase 2 Pipeline work is R.L. Alia Company of Seattle. The construction work in the creek is scheduled to begin about J�. Thank you for your assistance.

We will be making field checks on utilities next week and will he ready to advertise on June 7, presuming we can obtain D.O.E. approval to do so by then. Specific things you may wish to comment on are: 1. Full width repaving. The pavement structure sections illustrated arp my recommendations; however, the City may have other preferred sections or materials. I believe the full width repavement is most practical for the streets involved; but I would appreciate your thoughts on this too. 2. The casing carrier pipe replacement can be deferred if we allow surcharge to take care of additional flow. I think Bob may prefer to allow a surcharge condition in the casing sector and not tackle carrier pipe replacement. 3. Prequalification requirements are outlined. I took out the requirement of submission of two years of financial statements because this was challenged or ignored by contractor's on Phase 2. Advise if you prefer not to prequalify contractors on this contract. 4. We don't have an accurate index of existing flow in the Phase 3 sewer system and a metering station is proposed. The logical location for a metering manhole is in N. 28th Street. The purpose of the metering manhole is to m ke sure REPlYTO. ❑6EARLE ❑WENATCHEE Mr. Don Monaghan May 28, 1985 Page 2 we set the pumping rate such that we don't "drown" the downstream sewers. A system to regulate the pumps is being integrated into the pump station in conjunction with some valving changes Gary Morrison requested. These are the main review items tha,. occur to me.

An agreement regarding granting an easement on one section (although generally agreed to verbally last year) has now become an issue to resolve. It may be necessary to delay this contract for some period of time or simply terminate the schedule D portion of your contract. Some type of power arrangement to test and maintain the pump station will be required. We don't have answers on all the options yet. However, you should plan to continue to defer schedule D work. Bob plans to have a better estimate of options within the next week or so. Therefore, we will set June 3 as the date to resolve how the schedule D contract portion of our work will be handled.

W. Scott. We have reviewed the initial proposals with Tom Kivley and Run Scott and negotiated adjustments where appropriate. Change Order 01 Tempor,.ry Fence This work has been completed based on verbal authorization to the contractor. Addition of the fence was required to reduce unauthorized entry and satisfy adjacent property owners requests. Change Order #2 Pump Station Relocation Weak surficial soils of approximately 5 foot thickness slid at the original design location. Fir safety and cost reasons it was deemed appropriate to relocate the pump station to the west side of the 54 inch culvert. The change order consists of making payment for the proportionate share of site development costs incurred prior to the slide. The differential costs of site features at the relocated site versus those at the new site are included in the change order. Foundation stabilizatiol, will be required based on a test pit dug by the contractor; therefore, allowance for heavy rock bedding of the 6' horizontal wet well is also included. The foundation base is considered a changed condition and wc.:ld be an extra to the original contract.

All materials for the pump station are on order and have been approved. Gary Morrison with the City has requested that we consider using a wafer check in lieu of the conventional check valve specified. His comment is that they've had pitting of conventional check valves for the type of installation we've designed. We have not used the single leaf wafer check valves in a sewage system; and, we will appreciate any advice on use of a wafer unit for the Honey Creek Station. Specifically we would like some comparative detail on headloss through the var+ous wafer options -ersus a conventional cneck valve. The contractor R. W. Scott Construction Company has ordered all pump and plucbing equipment through H. D. Fowler. We do need to make a quick decision on any change; and, we will thank you for your prompt consid- eration.

He wants to obtain a change order proposal for the changed location; but, we can proceed on cleanup of the east bank as we discussed. Bob agrees that the east bank cleanup work including diversion work you've already accomplished should be done on a force account. This work needs to be carefully documented as to time and materials charges. Please provide us detail each day on hours spent and costs of materials with weigh tickets for backup. Larry Larson will check with you daily on this and we will have personnel on-site to monitor progress. I've enclosed APWA force account samples, you should use this format in submitting billings for payment. Please get costs and charges for the by-pass work to Larry Larson. You ex ressed concern for personnel safety in your letter dated April 24, 1985; nd, we exptct you tc make decisions relative to proper safety standards. If the large tree needs to be taken down, so be it. Trench work for the 6 foot pipe will be eliminated on the east side and removal lir;ited to slide debris. Bill La Pldat has provided some sketches for your information. Sketch A is the desi -ed arrangement we want to build; additional spalls can be used if necessary. The objective is to hold the bank and permit creek restoration. A future road will probably be constructed over this area under Phase 2 work. Please contact Larry Larson or me when you are ready to proceed with the force account cleanup work. When we °inish up 'he layout for the west bank pump station relocation, we' ll get blueprints to ycu so we can then establish a lump sum contract adjustment for the relocated pump station. We anticipate finishing this layout by Munday April 29th.

Prior to starting construction on the pump station, in March, R.W. Scott Construction Company excavated two test pits to determine sufficiency of areas for pump station construction. The test pits were excavated at about the mid-point of the storage structure one west of the 54" culvert and one east of the 54" culvert. Thi test pit on the east, side revealed competent material . Toni Kively made a subsequent excavation near the wet well chamber which revealed apparent good material . On April 18, at the south end of the storage structure, wet 5't deep surficial overburden slid on a glacial till interface during excavation. The slide pushed over the ecology block wall and partially dammed the creek. The Fisheries Department was notified Thursday, April 18th; and, Joe Robel gave an emergency bypass authorization to route the creek around the slide debris. Bill LaPrade of Shannon and Wilson and I took measurements on the slope plane Friday afternoon and probed the area. As a result of this investigation we determined that the slide was h+sically surficial material (averaging 5 feet thick) that slid on a very der•se till plane. A recommend- ed method for correction is to 1) remove the extensive soft material debris back to the dense glacial till; 2) set the storage structure on i rock spall foundation (bottom of spalls at or below creek flow line); 3) backfili the excavated void with clean pit run sand and gravel while progressively building a gabion wall on the stream side of the storage structure. This method was reviewed with Joe Robel Monday morning, April 22, 1985; and, he agreed to issue a permit to reconstruct features in and adjacent to the creek if we would send a drawing of the reconstruction prorused. A drawing REPLY TO 0 SEATTL.E ❑WENATCHEE Mr. Bob Bergstrom April 25, 1985 Page 2 was sent to Mr. Robel ; and, a permit for construction is to be issued Friday, April 26, 1985. During construction of the emergency bypass the surficial materials have continued to break away; Tom Kivaly gave me a letter Wednesday morning, April 24, 1985 at R.W. Scotts office relative to concern for safety during excavation. This concern coupled with a fairly expensive ($40,000) cost to stabilize and rebuild the bank for the pump station prompted a decision to move the pump station site to the west.

It appears that the face exposeG just uphill from the slump is hard dense till . There are some loose sands perched On the till above which could continue to slip down. Our conclusion was that the soft slide debris should be excavated back to the dense till (see sketch;. The test hole was located between 2 slough areas; so a similar situation could develop north of the pump station. Therefore the same recommended procedure of excavation applies along the entire pump station site. The depth of soft material relative to stream bottom is not known. Therefore the material should be cleaned out to firm base or to creek bottom elevation and several feet of crushed fourdation rock placed under the pipe to key the embankment in. All backfill material should be clean pit run gravel so that water seeps out. The fisheries people may prefer to use gabions rather than concrete blocks. We will get a better reading on this today, April 22, 1985. Bob Bergstrom requests that we come to an agreement on extra work before we proceed. So if you will prepare a changed condition proposal we will try and get you started back up again as quickly as possible. Sincerely, Frederick G. Kern, P.E.

Our conclu°.ion was that the soft slide debris should be excavated back to the dense till (see sketch) . The test hole was located between 2 slough areas; so a similar situation could develup north of the pump station. Therefore the same recommended procedure of excavation applies along the entire pump station site. The depth of so' t material relative to stream bottom is not known. Therefore the material should he cleaned out to firm base or to creek bottom elevation and several feet of crushed foundation rock placed under the pipe to key the embankment in. All backfill material should be clean pit run gravel so that water seeps out. ThL fisheries people may prefer to use gabions rather than concrete blocks. We will get a better reading on this today, April 22, 1985. Bob Bergstrom requests that we come to an agreement on extra work before we proceed. So if you will prepare a changed condition proposal we will try and get you started back up again as quickly as possible. Sincerely, L Frederick G. Kern, P.E.

The unit should be furnished with the flexible connection rather than the close coupled unit noted in the submittal data. 2) The suction elbow is to b, eliminated and the inlet fitted with a vertical suction pipe. 3) The sizes and locations of the vacuum priming pumping connections to the body of the Clow pump and suction connection piece should be approved in writing by the Clow factory design engineer as suitable for intended pump operations. Clow factory personnel should refer to the specific design plan when preparing a response. 4) We have also asked H.D. Fowler to provide comment on vertical suction connection piece size.

Motor, City Clerk From: Richard Houghton, Public Works Director Re: Honey Creek Sewer Interceptor Professional Services Contract Amendment No. 3 Please have executed the attached Amendment No. 3 on the Honey Creek Sanitary 1Z::wer Project Professional Services contract with HCWL Engi- neers. City Attorney review is attached. This project is the Honey Creek Sewer Interceptor which the City has received Department of Ecology Referendum 39 Grant Funds, This pro- ject is on a "fast track" short construction schedule. About $1 .2 Million dollars of construction work will be compressed into several months of time this summer. Amendment No. 3 provides full time con- sultant inspection and construction management on this large project. City staff is unable to cover this project in addition to our already scheduled projects. The issue raised by the City Attorney on costs is, of course, a legitimate question. However, the Inspection fee of $77,500 amounts to about 6% of the construction project cost of $1 .2 Million dollars. This compares favorably to other inspection costs such as Grady Way Bridge, $750,000 inspection and construction management fee on a $4.5 Million dollar job - 16.6% cost of inspec- tion. It is the department's recommendation to do this work. After execu- tion, please return a photo copy for our files.

In reviewing available access down from Honey Creek Estates, Ken advised that the corridor on City land is too restrictive to build a road in the steep area. If easements can be secured, then the road can be added. In the meantime until a decision is made on easements, we've deferred this road design. We intend to put in a unit for willow saplings if desired. However, this work may better be accomplished by others. We can discuss this in more detail when we talk with Joe P,obel .

The ductile iron pipe is capable of resisting large rock damage and the polyethylene pipe selected also has design reserve for tough handling and rock. The AWWA C-900 PVC is tough T but I 'm not satisfied that it could meet the same criteria for selection. e--- , So I 've eliminated it as an alternate. We have not yet used polyethylene on a large job; so, I carefully researched the merits of various manufacturers of polyethylene pipe. The polyethylene pipe we specified has a higher melt index which separates it from other polyethylene resins. The resin used in manufacture of the product specifies results in longer molecules which from my research indicates it has less notch sensitivity; and, therefore it would be tougher for the in creek location where rock impingement could conceivably occur. A good friend of mine in the construction business has given me the best verification of the selection we made. He states that the 8600 Drisco pipe (which meets the spec) is more fool proof in fusing. We personally will use no other poly pipe for underwater application if he has a choice. Additionally, he indicates that in their own dredging operations, they' used 26 inch polyethylene and given it rough treatment including kinking. The material has been used and reused and they believe the product is definitely superior. As I mentioned this could be an issue which manufacturers, who choose not to use the resin and process to meet our specified material , will argue with. It may be well for us to discuss this in more detail . We can discuss further after you make your final review.

February 26, 1985, Letter Comments: 1. Any trees and shrubs planted will he placed as directed; however due to bank steepness planting other than hydroseeding on access road banks are not planned. a. The in stream trench incorporates large rock for pipe protection with permit required gravel above. This will be further discussed with Mr. Robel , b. For roadway we have used a scour protection rock wrapped into the existing slope. c. Limits of scour rock stream crossing will be field determined because it is bid at a unit price. Also spawnine, gravel pro- visions at crossings and under bridges will oe included. Spawn- ing gravel is bid at a unit price. 2. Maintenance road bridges and details are now shown. RERY TO. ❑EEATT1t ❑wtw HEE Mr. Ed O'Brien March 14, 1985 Page 2 3. The curvilinear pipeline maintenance is considered nil due to the steep existing stream bed grade. If creek or pipe maintenance is required access will need to be made via side lots generally perpendicular to the thread of the stream. A road above 68 + 30 is not considered impossible but economically impractical . A. The tributary stream has fairly small flow. However two pipes were selected to provide redundancy for potential plugged condition. The pipes were oversized to m0imize maintenance commitment. 5. Acknowledged. We normally consider tees and pipe within confines of right-of-way or easement as part of the public system. City will obtain clarification on ruling before requesting grant reimbursement for same. 6. The characteristics of the curvilinear pipe normally precludes maintenance when placed at steep slope. The lengths between cleanouts were selected to accommodate City equipment. An independent-statement from the maintenance department can be provided if necessary. 7. Acknowledged, now completed. 8. Locations confirmed. Detail provided from DOE water-sewer clearance criteria. 9. All permits have been secured. 10. the connection between Manhole No. 1 and Manhole No. 3 was made for future operational considerations to intercept flow into the gravity system. 11. Bidding documets now specify a completion .ime, liquidated damages and award provisions. March 6, 1985 Letter Comments: 1.

CONSULTING ENGINEERS 4010 STONE WAY NORTH SEAUtE, WASWNfiTQU 98103 CONTENTS o Brief Summary o Storm Water Flow Estimation and Stream Characteristics o Scour Protection Rock Sizing Summary The following computations were completed to find the following: 1. The instream construction of the sanitary sewer required a scour protection rock cover which was large enough to withstand scouring from the heavy storm water flows. This rock also requires a gradation of smaller rock to eliminate downward movement of the bid rock causing possible breakage of the sewer pipe. The established gradation is shown in the co ,utations. A rock size large enough to withstand the scouring forces was found to be in the range of 6 to 9 inches. 2. A maintenance road will be installed along approximately three fourths of the sanitary sewer installation. This access road must cross the stream by bridge in two locations. The stream characteristics were estimated to determine width and depth of flow for bridge design and a relative vertical distance between the access road surface and the stream bed. The 100 year stream flow was estimate,' in the range of 140 to 180 cubic feet per second. A nomograp,', was used to estimate the stream veloc',ty at approximately 6.4 fps and a stream depth of approximately 1.7 feet. This estimation assumed a stream bed width of 10 feet which is generally conservative. For determining the minimum clearance and span of the bridge a conservative 3 feet was added to the approximate maximum stream depth of say 2 feet to provide a 5 foot clearance. A 20 foot minimum channel width for the bridge crossing was found to be conservative. This allows for some debris passage in addition to sufficient capacity for stream flow. The minimum vertical distance between the access road and the stream bed will ordinarily be in the range of 1} to 2 feet. The road surface is constructed of scour protection rock to elimi- nate stream bed migration into the road. Z of I s �: � , -s.''r.'£'V>�" .

Warren, City Attorney RE: Honey Creek Sewer Interceptor-Professional Services Contract Amendment No. 3 Dear Bob: I have reviewed the contract, Amendment No, 3, and find it to be in generally acceptable legal form. I do question whether or not the scope of work as detailed herein s worth $77, 500 .00 . That figure seems high to me . I particularly note that there are separate inspection estimates for Phase I and Phase II of the project with 320 hours being dedicated to Phase I and 420 hours being dedicated to Phase II . In each instance that amounts to approximately one-half of the bid amount . However, the description of the inspection services as contained in paragraph 3 .1 leaves me wondering whether or not we really are getting the inspection that we are paying for. I am not really aware of the magnitude of this project. Perhaps it is necessary for the Engineer to have periodic on-site inspections amounting to almost 900 hours. If so, I anticipate that the City is going to have a full time inspector on the job. I see that as the number one concern about this contract. I do not wish to second guess the Public Works Department but I felt uneasy about this particular topic and hope that you will review the time and figures before having the contract signed. If you find the time and figures are reasonable, then 1 have no objection to this ccntLact . awrence J�Qarren LJW:nd cc: Mayor i INTEROFFICE CORRESPONDENCE Date TO; FROM; Maxine E.

In some areas slopes - c11c s1iie. Tc best account for what we should budget for as a potential contingency or fork account work, geotech review of geologic conditions is being in-4er akvn. Scope of Geotech 1) Look at hill areas which will be cut, Phase I & 2, determine where and what type of drainage relief (if any) would be good to plan for and budget for some horizontal or other drains to include in force account contingency. 2) If sliding occurs what slip back removal should be anticipated and budgeted for as a contingency dollar amount now. 3) Which areas should be most carefully watched for signs of major slide potential during construction, Proposed Specifications The following is extracted from the draft proposal incorporated in Phase 2 documents and provides an overview of how the slope contingency is to be handled in the field by force account. W6-25 REnr To. ❑fEATTLE ❑wENATCE(¢ Force Accounts Work Some bank drainage procedures and or removal of slide back area may be required (refer to Technical Provisions Section 12-3.07). To efficiently effect corrective action for any bank contingency conditions that may be required a contingency force account allowance has been established to reduce delay. The Field Engineer will have limited authorization to schedule corrective action force account from this allowance if such work is required. The amount of the contingency allowance is set as a not to exceed amount. If no adverse bank stability problems are encountered the fund will not be used. Payment for force account work will be made only when specifically autF,orized by the Owner written order to the contractor. The Engineer may permit c direct changes in alignment such change will not be consider to be paid for from the contingency allowance; but rather, alignment change will be adjusted by use of applicable unit prices as set forth in the Contractors proposal . The contingency fund applies only to unanticipated bank stability soils conditions which may be encountered. The firm Shannon & Wilson has been retained through Owners consultant to provide technical advice on procedures to the Engineer and permit a more expedient resolution of any stability problems. When directed by the Engineer and approved by the Owner in writing the Contractor shall take action to provide any bank drainage and remove slide bank zone. The Contractor shall submit certified payrolls, equipment rental rates and time sheets, and material invoices to substantiate all force account statements.

V6G 1A5 Re: City of Renton, WA Honey Creek Sewer Project Dear Tony: We appreciate the information you have provided us in evaluating the use of polyethylene pipe for use in the City of Renton's Honey Creek project. Because of the specific terrain selected, test pressure and other consi- derations we have, with the City of Renton public works department approval , opted to use the following in creek materials options. 1) Class 51 Ductile iron pipe. 2) Class 150 AWWA C900 PVC. 3) Ultra High Density Polyethylene Pipe ASTM D-335 355434C. Some may not agree with our cho . es but we have researched and evaluated the materials issue carefully and trust you will accept our decision on the materials options selected. Thank you for your assistance. If you do have concerns or questions, I would greatly appreciate your contacting me directly rather than the City of Renton. Sincerely, Frederick G. Kern, P.E.

This project being environmentally sensitive and also quite out of the ordinary seems to be a natural for construction management. For example, if unstable area is encountered, a programmed procedure to reduce the likely- hood of claims makes good sense to me. The City has to be in a position to rapidly respond to any changes that may be necessary to avoid claims. Therefore, a X rmat for procedures change related to a construction management program, I believe, should be integra`ed into the contract.

If the GRANTEE fails to name an item of cost in the request for payment, this does not imply it is either allowable or unallowable; rather, determination of allowability shall be based upon the treatment of similar or related items of cost. 1. Factors Allowing Costs: In order to be all wable, costs must: a. Be necessary and reasonable and not be a general expense, b. Not be prohibited by any laws or regulations, C. Conform to any cost limitations or exclusions, d. Be consistent with state and federal (when applicable) policies, regulations and procedures, e. Be given consistent treatment through uniform accounting principles, f. Not be allocated to or included as a cost of any other state/ federallv financed program, past, or present, g. Be net of all allowable credits. 2. Certification: To assure expenditures are proper, vouchers requesting payment must be certified by the GRANTEE. Form A19-1, has a certification provision which must be signed by the GRANTEE or his/her authorized representa- tive before payment will be allowed. 3. Credits: The applicable portion of arty income, rebate, allowance, and other credit relating to any allowable cost, received by or accruing to the GRANTEE, must be credited to the DEPARTMENT, either as a cost reduc- tion, or by casn refund, as appropriate. 4. Unforeseen/Emergency Expenditures: A contingency line item proviaing a specified amount for reimbursements for unforeseen expenditures may be made only with the prior written approval of the DEPARTMENT. 5. Allowable Expenditures: No request for pavment will he honored for those expenditures incurred before the commencement date of the agreement, or after termination of such agreement, unless otherwise agreed upon in writing. B-1 6. Contract Provisions Controlling: Where any discrepancies between the specific provisions of the agree- ment and the applicable cost principles arise, the agreement provisions shall apply. 7 . Deviation From Major Project Elements: Payment will be disallowed when the GRANTEE's request for reimburse- ment of a given major project element exceeds that element's total by more than five (5) percent without prior written approval. Pro- vided, however, total reimbursement will not exceed the total agreed compensation. S. Phone Number: The GPANTEE mast include his/her business phone number along with the documents requesting ps.-ment so that expeditious processing of such documents may proceed without delay should any questions involving the request for payment arise. 9. Instructions - Form A19-1: Specific instructions for filling out the A19-1 voucher and supportive documents are found in Financial Guidelines for Grants Manageme:t , Chapter 6, published by the Washington State Department of Ecology (DOE) . A copy of this text is available from the DEPARTMENT and is furnished to all GRANTEES. 10. Cost Object Breakdown: The documents supporting each request for payment must have a brief concise breakdown of each cost object under the agreement, along with a brief explanation for the charges. 11. Allowable Costs: Generally, whether costs are allowable depends upon cost princtpl�s applicable to the particular project agreement. However certain costs are commonly allowed. These include: advertising compensation for personal services depreciation and use allowances employee fringe benefits employee morale, health and we.fare maintenance and repair materials and supplies memberships, subscriptions and professional activities taxes training and education transportation travel B-2 Employee benefits in the form of regular compensation paid to employees during periods of authorized absences from the job, such as for annual leave, sick leave, court leave, military leave, and the like, if they are: ( 1) provided pursuant to an approved leave system, and (2) the cost thereof is equitably allocated to rll related activi- ties, including grant programs. Employee benefits in the form of employers' contributiin or expenses for social security, employees' life and health insurance plans, unemployment Insurance coverage, workmen's compensation insurance, pension plans, severance pay, and the like, provided st :n benefits are granted under approved plans and are distributed equitably to grant programs and to other activities. Where any questions involving allowability of costs arise, the DEPARI- MENT contracts officer should be consulted; otherwise, certain costs may be disallowed. 12. Payroll and Distribution of Time: Amounts charged for personal service, regardless of whether treated as direct or indirect costs, will be based on payrolls documented and approved in accordance with the generally accepted practice of the state or local agency. Payrolls must be supported by time and atten- dance or equivalent records for individual employees. Salaries and wages of employees chargeable to more than one cost objective moat be supported by appropriate time distribution records. The method used should produce an equitable distribution of time and effort. Such time records must be certified by the project director. Such certified records are the only allowable source document for charging and report- ing personnel expenditures. 13. Costs Allowable With Prior Written Aerroval: Certain costs require prior written approval of the Federal granting agency and/or the DEPARTMENT. Costs requiring prior approval Lnclude indirect costs, some direct costs such as equ!pment, insurance and indemnification, and preagreemee,t costs. Again, reference to cost principles and consultation with DEPARTMENT officials should eliminate anv questions and possible rejection of incurred costs. 14. Unallowable Costs: Certain costs are commonly disallowed. These unallowable costs include: bad debts contingencies conLributions and donations entertainment fines and penalties interest and other financial costs unde n ecovery of costs under grant agreements Once again, whether a cost is unallwable depends upon the applicable cost principles to the agreement. Failure to clarify any question whether a cost is unallowable or allowable may result in its disallow- ance by the DEPARTMENT. B.-3 APPENDIX A SPECIAL CONDITIONS MI. Design/Construction. This project will be designed and constructed in accordance with applicable provisions of Chapter 90.48 RCW and Chapter 173-240 WAC. The construction shall conform to the plans and specifications and major change orders approved by the DEPARTMENT. M2 Payment Limits. The total estimated eligible cost for design (Step II) of this project is S _ Payments toward design. (Step II) will not be grant eligible until an engineering report has been approved by the DEPARTMENT. Payments toward construction (Step III) will not be made until the plans and specifications have been approved by the DEPARTMENT. M3. Construction_Bid Overruns. A 10 percent contingency figure will be allowed on the estimated bid :onstruction costs per major project element used as the basis for this grant as identified in Appendix A. If the sum of the lowest acceptable bids in each major project ele- ment is in excess of the amount of this grant, including the 10 per- cent contingency, the grantee will be responsible for the increased cost. M4. Grant Amount AdLustment. When the lowest acceptable bid(s) has been approved for Step III, the construction cost element(s) will be amended. The "construction estimated bid" line items(s) shall be changed to "construction" and the dollar value, excludi% , ..ales tax, changed to the approved bid amount, but in no event shall the SLIM of the "construction" line item actual bid amounts exceed 110 percent of the original estimated bid construction costs for each major project element. The 10 percent construction contingency line item{s) will be eliminated and replaced with "change order" 0%) line item(s) for each construction line item. The "change order" line item(s) will be calculated at 5 percent of each new "construction' line item. The remaining line items will be revised t� reflect these adjustments. 115. Change Orders. All change orders must be approved by the DEPARTMENT. If they are declared eligible for grant funding the DEPARTMENT will pay its predetermined grant percentage share of those change orders %,hose cumulative total for each construction line item does not exceed the 5 percent allowance. The GRANTEE will be responsible for all costs associated with change orders exceeding the 5 percent allowance. M6. Construction Schedule. Within 30 days after the award of the construction contract, the GRANTEE will submit to the DEPARTMENT a copy of the actual construction schedule and a CPM diagram of the proiect, by month, for the entire construction period. When the time for the construction of work exceeds three calendar years, these diagrams must show monthly goals, except during the last calendar year of work, when only quarterly goals need to be show. M7. Force Account. The use of force account is permitted for any Step I, II, or III grant work provided that prior written approval is obtained from the DEPARTMENT. Approval is based upon the GRANTEE'S ability to show that he/she possesses the necessary competence to accomplish the work, that the work can be accomplished economically, that adequate cost-accounting records can be maintained, and that use of force account work is legally allowable. M8. Operation and Maintenance Manual. An Operation and Maintenance Manual shall be prepared in conformance with WAf. 173-240-080 and the DEPARTMENT'S guidelines, and submitted to the DEPARTMENT for review at the 50 percent stage of the Step III process. A com- pleted and approved Operation and Maint-cnance Manual shall exist at the 90 percent stage of the Step III process. Failure to comply with the above may result in the withholding of payments by the DEPARTMENT. M9. Plan of Operation. A Plan of Operation shall be developed by the GRANTEE in conformance with the DEPARTMENT'S guidelines and sub- mitted to the DEPARTMENT for review and approval no later than the start of construction. The Plan of Operation shall be updated at the 50 percent and 90 percent stage of Step III (or more often if significant project changes occur) and resubmitted to the DEPARTMENT for approval. M10. Grant_Percentage. The DEPARTMENT has determined that the con- struction costs of this project are percent eligible for grant participation. Mll. Architectual/E�gineering Contract. The GRANTEE shall submit a copy of the final negotiated A/E contract to the DEPARTMENT fifteen (15) days prior to execution. The A/E contract will be reviewed to ensure adequate scope of work, level of effort, reasonableness of costs and responsibility for testing by the consultant. This review is required for A/E contracts for both Step II and Step III work. Grant eligible funds will be disallowed for A/E services performed prior to an executed A/E contract. M12.

The construction quality assurance plan must show how ade- quate and competent construction mai.agement will be provided by the GRANTEE during Step III. The plan must include the requirements of Chapter 173-240 WAC and appropriate DEPARTMENT guidelines. M13. On-site Wastewater Disposal Ordinance. The GRANTEE shall implement a DEPARTMENT approved On-site Wastewater Disposal Ordinance for the designated service area prior to award of bid for Step III construction. A-2 7lfH �J -lf v Memorandum of Progress TO: Bob Bergstrom FROM: Fred Kern DATE: December 27, 1984 RE: Interceptor Sewer - Honey 9% Creek Summarized below are our preliminary thoughts and •ecommendations togetn- er with a little background. Pipe Materials I 've briefly discussed with contractors and Larry Larson my desire to use efficient cost competitive materials. A general conclusion is ASTM D3034 PVC is not suitable for our stream bed environment. Materials that appear best suited are Ductile Iron and Polyethylene pipe. Relative costs of materials only are: PVC ASTM D 3034 $ 5.00/ft Poly Pipe SDR 325 $ 10.00/ft Duciile Iron Class 50 $ 12.50/ft Ductile Iron Class 51 $ /ft Pipe Geometry Option 1 - Curved pipe presents serveral advaritaoes and the pipe best suited for cureed alinement is Polythylene pipe. Polypipe in 12 size is capable of radius down to 30 feet. Most of the stream bed radius are much greater with minimums in the range of 50 feet. A layout with this concept is enclosed. ASTM D3034 can be constructed to no less than a 300-400 foot radius according to the manufacturer recommendations, (see attached). Curvature for plastic pipe is not predicated on joint deflection as is the case with ductile r OEM iron. As a result there is not a great deal of benefit in using the curved alinement with ASTM D3034 PVC pipe. From Station 30+ 50- (Pump Station) up to 68+ 50a the sewer main location is illustrated outside the stream bed to comply with fisheries requirements. F• Station 68+ 504 up to Station 81+ 00± the pipe is located in the stream bed. In either location the value of the tight curve radiia capability of poly pipe permits the best least expensive routing and the least disruption. To permit in stream location a cleanout concept is mandatory because manholes coula not be set in the creek. We propose to use cleanouts through the entire creek interceptor run. The cleanout concept provides excellent interceptor location adjustment. That is, if we adjust the main location we just add a little length to the cleanout to best position the cleanout oper,ing in a protected location. I Sstem Dependability The polyethylene pipe concept provides several features that make it ideal for the Honey Creek interceptor. 1) Geometry - Easily laid to any reasonable radius with no concern about join; leakage associated with a deflected pipe apro . Contractors I've discussed this material with believe Honey Creek is an ideal application. 2) t ntinuity - The steam bed or adjacent ground can be eroded by extreme storm conditions with a continuous pipe even if erosion of a portion of creek bank occurs the pipe still has continuity with no joints to come apart. 3) Strength - The high density poly pipe has tremendous impact resistance and therefore has better application in a though stream bed environment. 4) Leakage - The creek location guarantees that the pipe will in some areas be continuously underwater. With no joints to be concerned with poly Z- _ i pipe literaliv assures a leak tight system. Ali Tent Fisheries requirements to keep pipe out of the stream bed compounds construction problems because trench excavation on steep side slopes is more difficult and must be installed deeper than an in creek configuration. Except for a few crossings the locations of the line is illustrated outside the stream channel defined on the drawings in areas stipulated by Fisheries. Even though we have illustrated the pipe line outside the creek, we believe that it li can be demonstrated that in stream work during selected summer months will substantially accelerate the stream "healing" by avoiding vulnerable soils on I steep side slopes. Approaching fisheries with this type of rational construction procedure ` to enhance the stream fish productivity may be best left untii construction i commences. In stream bed excavation will require a stable non-erodible backfill over the pipe. We have analyzed flows and veloci 'es for several types of storm. Tke erosion force of storms analyzed has moderately high velocity capable of rolling fairly large stone. We are now researching the best protective material measures necessary to provide pipe and stream bed security. Integrating features which enhance the stream from a fisheries standpoint will also be reviewed as they relate to stream rebuilding. Pipe Depth and Excavation Our design criteria proposed is to dig about 2'-6" below the stream bed in areas where the bed is in hard pan and some additional depth where the stream bed may be in alluvial deposit zone. Typically pipe would have a 4-/-inch cushion of gravel above and below the pipe and a I foot layer of erosion control balla. '. I Maintenance Consideraitons i 1) Road - Access to the cleanouts along portions of the pipe is con0&ren essential . In all probability the smooth continuous steep gradient pipe will never experience clogging, A c ... 3,. _. `.P gg g, procedure that abuia;.es routing maintenance need for a road would make "water splash" type crossings more acceptable for emergency. Therefore, in obtaining fisheries concurrence to construct water splashes in lieu of bridges, the emphasis should be that an access way along the creek will be principall, construction related and not used routinely by the City for maintenance. 1 2) Continuous Reach Cleaning - With the curved continuous pipe barrel , the continuous reach cleaning maintenance concept is to routinely "pig" the pipe. That is start a scouring ball at especially designed maintenance manhole and allow the "pig" to traverse the entire interceptor line down to the large pipe wetwell . This maintenance procedure would require a letter or other reasonable retrieval system to fish the Pig out of the wet well . A 12" pipe stoppage with the system proposed is unlikely; however, frequently spaced cleanouts assure localized accessability For manual transported apparatus. 3) Curved pipe in close proximity to the stream requires a protective barrier to keep excavated soils from muddying the stream. For shallow depths excavating equipment can be of modest size if pipe location is kept close to the creek. The sewer pipe trench excavation should be entirely wasted and hauled away from the site and replaced with selected bedding of partially crushed product that will have some keying property and prevent migration of the heavy ballest. Heavy ballpst sized in the I � I I ' 4-6" range will protect against scour forces. The ballast can be sculptured in various areas to provide stream grains to contain selected spawing gravel . In very confined areas of the creek the roadway location can diverge from the creek to avoid longitudinal maintenance travel in the creek. The main- �I tenance road will be routed to access cleanouts along this route. The capacity of the 12" pipe is such that it can be nicely used to flume water around the areas to be excavated. The entire stream could be contained in this fashion from roughly station 68 down to the pump station. The concepts set forth seem to us to br very r-asonable that is: 1) Use curved pipe with a continuous tube access for pig. 2) Provide cleanouts for emerging accP1 oy construction road. 3) Provide the system that has the least probability of leakage at joints. 4) Provide a system that has gopd continuity in the remote event section of pipe trench are scoured away. To determine if the general design proposal made sense construction wise, we discussed the construction aspects of the concept to see what c')ncern; they may have. LA summary-of comets`are as followS. Our principal aEquest for input does this make sense cost wise and also does A provide a reasonably secure product to the owner.

Allowable deflection at the joint is minimal, and should not be considered in your calculations. The enclosed table #35 and diagram illustrates the maximum allowable bend of ASTM 3034-SDR35 PVC Sewer Pipe. Both taken from the Uni-Bell PVC Hand- boo k. Twelve inch sewer pipe can be outset 6. 80 for 12. 5' ten gfh pipe and 11° for 20' length pipe. Laying 12. 5' length pipe, each joint can negotiate a max- imum deflection of 6. 81; therefore, a minimum radius of 110' can be "pulled". Using 20' lengths of pipe, one can pull a radius of approximately the same value. Looking on table 35, you can observe the amuunt of force received to obtain such a deflection. A radius of 400, would require far less force applied to the end of the length of pipe. If we can be of any further assistance, please do not hesitate to call. .I Yours truly, yy�a�c� A.

The inaccessibility and slopes involved serve to create an installation which will be very difficult to install and maintain. Also, the long range stability of the embankment and thus the installation cannot be obtained in advance. Our recommendation is to serve the station via the existing overhead line on N.E. 27th Street. This would involve installing thrEe phase underground about G.2 mile from 24th and Edmonds to the existing pole line on 27th, Puget Power adding two phases to the existing pole line, and about 1200 feet of underground 3 phase on 27th to the station (common trench with force main OK). J As the City of Renton is determining how to install the station power the ramifications of this decision are the City of Renton's 31one. Very truly yours, SPARLING E ASSOCIATES, INC. Daniel G.

This is Metro standard. 2. Force Main - U.K. to use PVC - C-900 pipe. Can be "Blue Brute", but no so e—source call-out. 3. Watermain - Use 8" Class 52 Ductile Iron. City will do final design. us7' L lay out alignment on plans. 4. King County Permit - Please submit as soon as possible. Assume County pavement overly. Do not delay. 5. Fisheries Permit - Gravity pipe work is delayed until June 15, 1985 throug October 1 , 1985.

Shinpoch, Mayor (<;gAVnR'S OFFICE Municipal Building Renton, WA 98055 Subject: Professional Service for Construction Inspection Dear Mayor Shinpoch: The Public Works Department needs to hire consultants for assistance in construction inspection of public works. The Traffic Engineering, Engineering Design and Utilities Engineering Divisions have an extremely heavy load of municipally funded construc- tion projects and has, for the near terin, a heavy load of privately financed development construction projects, all requiring inspection. This shortage of construction inspection is acute now and will be criti- cal until this fall . We have considered hiring inspection services on the City pay r)il ; however, we are unsure of the strength of this current mini-construction boom, and we also recognize that some major municipally- managed projects, such as L. I .D. 314 in the valley, will be complete this fall . We feel that by using consultant inspection, while it is a higher hourly cost, also provides us the flexibility tc avoid overstaffing if the economic recovery falters. Our request for professional services would include: construction inspec- tion and construction survey. We propose to develop a roster of at least three and no more than five consultants that are pre-qualified through the selection process who would be utilized on a rotating basis to provide construction inspection assistance to the City on a project by project basis. This process is commonly used by the Corps of Engineers. City of Seattle and many local municipalities. The source of funds for this work is varied: Utilities Engineering will utilize their construction funds already budgeted for support and con- struction of approved water and sewer projects; Traffic Engineering will utilize federal and state funds already granted for support and construc- tion of grant approved traffic ana signal projects; Engineering Design will utilize funds already budgeted for support and construction of approved utilities or street projects. To: Mayor Shinpoch - 2 - June 6, 1983 If the work load becomes especially acute, the department will have to request that the inspection fee money collected from developers be diverted to support consultant inspectors on private development work. Our present inspection program collects about 2% of the value of the construction work in fees which can finance construction inspection. Our need for construc- tion inspection for developer work is not firm. At this time I request approval to hire outside construction inspection and survey services already funded and budgeted municipal construction projects using a roster of prequalified professional consultants.
