Both the Department of Ecology and the Department of Game made reference to the water quality in the existing city drainage ditch going through the Park. Among other recommendations, it was suggested that the City of Renton evaluate the water quality in this ditch prior to proceed- ing with the improvements. It may be of interest to the City of Renton and to the monitoring agencies to review the Pacific Car waste discharge monitoring program. All storm drain runoff from the Pacific Car plant leaves the pro- perty at three points. Storm drainage from the Foundry area is collected in a main at 6th and Garden which goes directly west down 6th and empties into the Cedar River. Other storm drainage is con- tributed by property owners along 6th. Storm drainage from the central area of the plant is accumulated in closed drainage ditches which divert the drainage into an oil separation pit located in the northwest quarter of the property. The water travels in an open trench through several oil separation ponds until it goes under- ground at 8th Street. The third storm drain line picks up water from the eastern portion of the plant. This line comes from the Renton Highlands and carries storm drainage from that area. The latter two lines join together roughly at the Shuffleton property line and flow through the Park into Lake Washington. Our Waste Discharge Permit, No. 5105, with the State Department of Ecology, permits us to put storm drainage into the system at these three points. In compliance with Section B of the Department of Ecology requirements, we have, since 1972, taken weekly samples of the water at the property line, analyzed it, and reported the results to the Department of Ecology. Temperature and Ph measurements are Mr. Don Monih0 -2- 15 April 80 made weekly. A heavy metals analysis is made every six months and reported to the Department of Ecology. Since starting to report in 1972, our temperature, Ph, and heavy metals concentration has been well below maximum state limits. I am enclosing our latest report to the Department of Ecology and also a report covering the period from 3 August 79 through 25 January 1980. Many of our employees are long term residents of the City of Renton and users of Gene Coulon Park. For this reason, and because of our proximity to the Park, we have been extremely careful over the years about the quality of our runoff water. Please advise if we can be of further assistance to you in securing the necessary permits to proceed with the expansion of the Park.

C> y r na" RUN kpff FEB. 13 1980 JVIVtb C? JVINCS consulting engineers February 11, 1980 Mr. David Roberts Jones & Jones 105 South Mein St.. Seattle, WA 98104 Subject: Gene Coulon Beach Park Investigation of Pollution Abatement Facilities for Existing Stream Dear Mr. Roberts: As requested we have completed our investigation of the pollution problem at Gene Coulon Beach Park. Due to the extreme complexity of analyzing all types of pollutants we have limited the scope of our investigation to oil and other visible forms of pollution. We have identified what we feel to he the problem and the relative importance of various contri- buting elements. We have evaluated three treatment methods with respect to applicability, degree of treatment afforded, cost and ease of operation and maintenance. Our findings are contained below. Preliminary investigation to determine the nature and extent of an oil pollution problem began by talking with Bob,-,.Ray from the City of Renton's Engineering Department. We learned that there has been a problem in the past with oil pollution resulting from spills in the commercial/industrial area which drains to the stream from the south. In the past few years there have been three major spills requiring U.S. Coast Guard investigation. One of these spills apparently involved several hundred gallons of gasoline. A visit to the project site was made on January 30, 1980. The weather had been dry and cold for approximately 10 days. We estimated the dry weather steam flow at 10 cubic feet per second. Oil sheens were visible on the water surface at a number of locations. The oil appeared to issue from small deposits trapped in weeds alpng the bank and from heavy oil in the bottom sediments. From a visual observation it appears these bottom sediments are also contaminated with trace metals. While investigating the drainage area we noticed a swale bordering the south fence of Puget Power's property. The area inside the fence was being used as a storage yard for transformers. Since some trans- formers contain PCB's, a powerful carcinogen, we feel that a public 700 Iloyd bldg., seattle, wo 98101 (206) 622-5822 (inchorcip) In; (in(7olon r v)rllnnd Jones & Jones February 11, 1980 Page 2 health hazard may exist at the park 's swimming area in the event of an accident. This situation may not be unique as the stream serves to drain a large industrial area. Further action is warranted and we suggest that Puget Power be notified immediately. From our discussions with the City and observation of the site and surrounding area it appears that oils in the stream are from two major sources: 1. Those pollutants carried in the run-off from parking lots and other paved surfaces in the upstream industrial area. 2. Pollution resulting from spills at commercial/industrial sites which drain to the stream. It appears that the oil which is visible during dry weather is a residual from the above. The treatment systems that will be discussed represent a wide range of sophistication, effectiveness and cost. The nature of oil pollution is such that all systems will not provide an equal degree of treatment. The oil that must be dealt with will be present in floating, dispersed, and emulsified forms, which represent increasingly difficult levels of treatability. Floating oils may most simply be removed by providing a physical barrier to their travel . The other forms require long deten- tion times or the addition of chemicals for removal. The costs that are given for the treatment methods are rough "ball-park" figures, which are for comparative purposes only. A substantial design Effort will be required to obtain useful construction estimates. The treatment alternatives presented all share some common considera- tions. First and foremost is that any system must be inspected and maintained on a regular basis if it is to be effective. The cost and ability to provide this service will be a prime consideration in the selection of the final treatment method. A second point is that the performance of any system can be enhanced by improving the upstream conditions. This involves education, mainte- nance and enforcement actions with the parties involved. We understand that the State Department of Ecology has had some success in this regard, especially with the large upstream industries. Thirdly, if a treatment system is put into effect and maintained, wastes will be produced which will require disposal ; in this case an oily water waste, sludge and sediments. � f Jones & Jones February 11, 1980 Page 3 The following treatment systems have been identified: 1. Large catch basin structures with T-outlets, installed on certain existing storm drains. 2. An open channel pond with floating boom and absorbent barriers. 3. Mechanical Treatment. Alternative # 1 - Modified Catch Basin This involves placing a large manhole or other structure over an existing storm drain pipe and providing a tee or baffle to trap floating oil. This is identical to the catch basin with a tight trap that is often used in parking lots where drainage is to surface waters. This system will function well to retain floating oil from a spill and during periods of low flow. During storms the small size of the structure, in relation to the flows, will create a large amount of turbulence. This will serve to disperse the floating oil, carrying it through the system. In many cases it will "flush" the system. The larger structures necessary to reduce this turbulence would be very expensive and not economical for the degree of treatment provided. The total cost of four structures to be placed on selected storm drains would be approximately $60,000. Alternative #2 - Pond and Floating Boom This scheme involves widening and deepening a portion of the stream channel upstream of the park property. A floating boom will be placed across the channel to catch floating oil . The enlarged channel area will provide an area of reduced turbulence and velocity for the recovery of some dispersed oil. This provides more effective treatment than alternative #1 during storm flow because of the reduced turbulence. It will be less likely to "flush" through. It also has an advantage in that any floating pollutants will he readily visible to maintenance personnel . A pond with 6,000 SF of surface area, five feet deep, complete with floating booms, bank protection and fencing would cost approximately $30,000. Alternative #3 - Mechanical Sy%trms This is the most sophisticated alternative. A number of mechanical treatment methods are available which include: 1) dissolved air flotation (DAF) 2) rotating drum and 3) filtration. Dissolved air flotation is the most feasible. Jones K Jones February 11, 1980 Page 4 In a OAF system the water is contained in a tank in which microscopic air bubbles are introduced at the bottom. As these bubbles rise they carry small dissolved and dispersed oil particles to the surface. An oil froth is formed which is then skimmed for further treatment. This system will produce the highest degree of total oil removal . Unfortunately this system has high operating costs and requires mainte- nance personnel who are familiar with the mechanical equipment. The cost for this type of facility would be about $0.5 million. It is our conclusion that if a pollution control effort is adopted, it should be directed toward containing accidental spills of oil and other floatable material and removing a reasonable amount of oil con- tained in storm run-off. To meet this objective we feel that alterna- tive #2, the pond with floating boom, offers the best solution. It has the advantage of low capital and operating costs, is tolerant of varying flow rates and provides a good degree of treatment for the money invested.

Joining together at a collecting basin are a 36 inch concrete pipe and a 30 inch concrete pipe from the east, both from Sunset Highway, and a 54 inch concrete pipe from Garden Avenue 11orth from the west. This primary collecting basin is heavily silted and water action has caused erosion that threatens the roadbed. Two 48 inch concrete pipes which cross a sanitary sewer transfer the water to a second collection basin combining with a 48 inch concrete pipe from the west. The second collection basin is directly above a 96 inch concrete sanitary sewer O'IETRO) and this basin empties into two 48 inch concrete pipes and one 42 inch CMP. At the present water level , the CMP carries 50 to 60 percent of the water, the other pipes used for overflow. A third collection basin then carries the water through two 48 inch concrete pipes and one 48 inch CMP to the fourth basin, which has heavy silting, to the Shuffleton entrance culvert, basically two 48 inch Ct1P pipes. From this point the stream flows clean with little or no silting through the park entrance culvert to Lake Washington proper. While talking with Gene Coulon, Parks Director, regarding the channel that follows the Park east perimeter, he stated that this area is a fill that had been placed on an old fill originally set by a small lumher mill and that the channel and surrounding area is interlaced with wooden piling, concrete bulkhead and trees including large quantities of rein- forced concrete sections , some of which are evident in the present channel and were not removed due to additional expense. The existing culvert under the park entrance during construction was set on old pilings. It appears that Mr. Coulon and the Park Board are not receptive at this time to any further work within the Park boundary. Some minor bank protection may find favor however. • To: Lyman Houk March 20, 1973 From: Gary Case Page 2 -------------- ---------------------------------------------------------- At present the water in the channel is below lake level , presenting silting problems at the mouth, as the beach is primarily affected by northerly winds forcing beach sand to wash into the mouth . A large hole is evident at the very mouth, which I presume is the result of earlier "clamming" . Proposals have been made for rechannelization by Bert Ross and his sketches are available for reference. On March b, 1973, I investigated the area and spotted many small salmon fry in the creek bed, together with muskrat, the full length of the channel including the first collection basin north of the Boulevard. Whether or not this channel is used for spawning or the small fish just gather there for protection, I do not know. Mr. Coulon stated that carp also used the water for spawning. Considerations One consideration for dredging, as requested by this office, has been to increase the holding capacity required by the increase of water runoff caused by the State on the Sunset Boulevard project. I also am informed that Puget Power would like the channel dredged as their storm line, from the asphalt lot at the Shuffleton Plant to the cahnnel , floods at high water. Mr. Coulon has informed me that the park and other properties have not flooded and that the culvert under the park entrance has not yet reached capacity in the last 15 years of storms. Since the removal of the Pacific Coast Railroad tracks will allovt removal of the culvert in that area, a large collection basin can be formed from the second basin to the third and be cleaned as conditions warrant. Cost would be minimal as compared to the total estimated cost, which did not include excessive excavation which the old mill and its resultant structures left. Cleaning on an "as need" basis would require occasional checking and "clamming" to provide adequate water retention. The first two basins would be cleaned at the same time. The first basin north of the boulevard will need extensive wall protection and if the flow from Sunset is as great as is anticipated, a small buffer wall may be added to direct the flow to the pipes. The same conditions prevail at basin No. 2 inlet and outlet. I feel that even this small improvement would be hard pressed to succeed considering the evidence of fish and other wild life in the area, with opposition from Fisheries , Ecology, etc. and the Park Board. I suggest further studies in combination with these departments before large amounts of money are spent, although Engineering designs have been proposed all of which will probably suffice. Extensive studies have been performed by Mr. Ross in the design flow characteristics of the channel . We do not have sufficient information on flood conditions at this time to determine if dredging through the channel mouth would be To: Lyman Houk March 20, 1973 From: Gary Case Page 3 ------------------------------------------------------------------------- of any advantage as far as alleviating the storm sewer problem. Many of the existing pipes are not at adequate qrades with slopes running reverse to the flow. Some adjustment should be made so that these pipes will be self cleaning but dredging of the channel would result in slower water movement due to the head present from the lake and I feel would result in greater siltation problems than we have at this time. Included are reports , designs and alternatives as proposed by Mr. Ross, including two (2) final designs. Which design has been accepted has not yet been made known to me. A rough draft of the specification has been completed and preliminary drawings (included) have been made. Profile views and X-sections for dredging and cost analysis are yet to be done. To date, I do not know if funding is available or have not been informed of what request for fundings have or will have to be made. I will need to know which plan to follow through, the deadline and the amount of funding available before any further work can take place . Thank you.

Renton, Wa. 98055 Attention: Mr. Bert Ross Dear Sir: Please refer to ,your letter of August 27, 1972 and subsequent meeting at the site concerning proposed improvement to drainage in the vicinity of our track near Lake Washington Blvd. No. at Renton, Washington. This will confirm our feeling at this point in time concerning this proposal ; namely, 1. All costs of the project must be borne by the city. 2. Inasmuch as the waters carried by culverts installed are surface drainage, it is not likely that we will be able to obtain union release for culvert installation beneath our track. It will, therefore , be necessary for our forces to install any additional drainage structures under our track. 3. The removal of present pipes and installation in a new location will require track to be out of service for a considerable length of time. We believe, rather than relocate three pipes and install new pipe, a change in plan should be considered whereby only the 72-inch pipe would be installed adjacent to the three pipes under the former Lake Washington Belt Line. The 72-inch pipe could be in- stalled with its invert elevation one foot below the present culvert inverts. In so doing., the present 48-inch culverts would be running full before the 72-inch pipe was completely filled. This change would require a revision in the alignment for the drainage system. 4. Use of the 14 gauge corrugated metal pipe with 3" x 1" corruga- tions will be satisfactory. 5. We see no objections to the removal of culverts beneath the old PC RR grade. The removal of culverts will allow water to flow freely with no possibility of future obstruction. i City of Renton -2- 9/20/72 You have since requested an estimate of cost for our forces to place the 72" culvert based on two bases : 1. Our forces to install pipe with the city to supply same. 2. Railroad company to furnish and place the pipe. I will arrange to obtain necessary field information in this regard and request our Manager of Engineering to prepare estimates. In our discussion there was some question as to whether or not the City of Renton would take salvage of the pipe to be removed under the old PC RR grade. I will refer this matter to our people and advise you at a later date concerning this particular item. It must be remembered when this work is done there should be adequate advance preparation and planning so that we may take the necessary steps to provide changes in our switching to the Boeing plant.

Grady Way Renton, Washington 98055 Attention: Sam Hansen Gentlemen: This letter is in reference to the storm drainage outfall in the vicinity of the City of Renton Lake Washington Beach Park. The City plans to relocate and enlarge the five crossings involved, one of which is beneath the Shuffleton Plant driveway to the Beach Park Access Road. Plans and Specifications are nearing completion and will be ready for bidding soon. The City sent a previous letter dated June 23, 1972, for which no recorded reply has been received. A copy of said letter is enclosed in case it was not received by your office and for easy reference. All information previously stated remains the same, except that the cross-section size of the proposed corrugated metal pipe-arch has been made smaller to reduce the cost from the previously estimated $9,50000 to $8,217.50. This fi ure includes material ($5,100.00) , installation (2,082:50) , road repair 0135.00� and earthwork (900.00). We would appreciate a response as soon as possible to minimize de l ay of the project. For further information, please contact the undersigned at Ba6-4810. Thank you for your cooperation.

Intlekofer, the City of Benton engrged the consulting firm of Cornell , Howland, (-:ayes, and Merry:ield to calcul ate a design flog; r,_.te from the contributing -area for a Uen-year storm. The con- tributing area has essentially remained the same, although due to street imrpovements and other storm drainage improvements that have been constructed and are in Ilanning stages now, the so-called "Time of Consentraticn" factor relating to hydrologic formulae has been re- duced and will be further reduced as various street improvement pro- jects are conpleted . This will result in decreased "surface retent- ion" which will allow rapid inflow into the system. Overtopping of portions of the ditch banks have also been exper- ienced, resulting in the x.ossibility of foundation instability, eros- Ion And eventual failure of embankments that would be affected . The poor alignment would also contribute to the 'possibility of embank- ment erosion at the many shads bends in the channel .

Grady ;stay Renton, Washington 98055 Attention: Sam Hansen Gentlemen: This letter is in reference to the storm drainage outfall in the vicinity of the City of Renton Lake Washington Geach, Park. This outfall presently • has five crossings , one of which is beneath the driveway to the Puget Power Shuffleton steam plant. All of these culvert crossings are presently overloaded, based on data from a five year storm drainage flora. The City of Fenton engaged the Consulting Firm of Cornell , Howland, Mayes , £d _1•';erryfield to calculate a design flow rate from the contributing area for a ten-year storm period. Their findings indicate that a flour rate of 370 CFS is applicable, and accordingly the crossings involved need to be re-designed to accommodate this volume. The crossing beneath the Shuffleton Plant driveway includes two (2) 48" CMP lengths , capable of carrying a maximum flow rate of 130 CFS.R�eplacement of the existing culverts with one large structure, ,%gill tja required to provide the capaci ty for handling the additional 240 CFS. The City of Renton hereby requests that Puget Sound Power z Li, Co. give consideration to the appropriation of the necessary funding to cover t e subject Shuffleton driveway culvert improvement. It should be noted that the existing culvert is inadequate even for a five-year storm flow rate. Addition- ally, it is the responsibility of each company whicPi has a facility crossing a natural stream bed to ensure the proper functioning of the crossing. We would recommend that a repiaceiv.nt culvert be used, consisting of a 12'-10"x 8'4" 10 cage galvanized multi-plate !pine arch , 86' long and with leveled ends. The approximate cost of such a system has been estimated at $9,500.00, including material , installation, earthwork and pavement restoration. I 2.

Intlekofer Region Manager Engineer Gentlemen: This letter is in reference to the storm drainage outfall in the vicinity of the City of Penton Lake Washington Beach Park. This outfall presently has five crossings , two of which are beneath railway lines. All of these culvert crossings are presently overloaded based on data from a five-year storm drainage flow. The City of Renton engaged the Consulting firm of Cornell , Howland, Hayes, & lbrryfi el d to calculate a design flow rate from the contributing area for a ten year storm period. Their findings indicate that a flow rate of 370 CFS is applicable, and accordingly the crossings involved need to be re-designed to accommodate this volume. Enclosed is a map of the general area of the crossings involved. Information from Jerry Bergman, Auburn Train master, indicates that the western-most railway line maybe removed this summer. If such action is taken further consideration for enlarging the culvert at that location would be `unnecessary. The remaining crossing includes one (1 ) 42" CHP and two (2) 48" concrete sewer pipe lengths , capable of carrying a maximum flow rate of 205 CFS. To improve flow characteristics it will be necessary to relocate the remaining crossing. Forty-eight (48") inch concrete culvert removed from present crossing locations will be utilized to construct 3 lengths of pipe, each 85' long at the new location. The installation of another culvert will be necessary for the additional 165 CFS flow. The City of Renton hereby requests that Burlington ;Northern give consideration to the appropriation of the necessary funding to cover the subject culvert improvement. It should he noted that the existing culverts are inadequate even for a five-year storm flow-rate. Additionally, it is the responsibility of each company which has a facility crossing a natural stream bed to ensure that proper functioning of the crossing. 2. Burlington Northern We would recommend that the additional culvert be 72" diameter, 14 gage galvanized corrugated steel pipe, 85' long.

We understand that the proposed roadway improvements by the Washington State Highway Department, which will contribute additional storm water to the culvert system, are now in the design stages. It would be our recommendation that consider- ation be given to improving the existing culvert system prior to the completion of that project so that damages from the anticipated increased flows resulting from that project can be minimized. ery trul urs , _t J E.

Installation of 4 'xl4 ' Box structure at the Park Road This box is absolutely required as this cannot accept the present flow if all the above items are corrected and the lack of this facility will cause overtopping and extensive flooding. A double box of 4'xl5 ' could also be. eor.sid.ered -'thus reducing the spans . Considerable extensive deficiencies exist in the entire storm sewer system in the City of Renton as indicated by reference report #8 by CH2M. A con- tinual updating of the deficiencies in the system will be required to obtain optimum efficiency . Respectfully Submitted, Cha les W.

Look what I found in going through my files, after I told you that I had never written a letter about the flooding problem in the North Renton area! Is my face red! ! It looks as if I took those slides and wrote Jack the attached letter of October 4, 1968, proposing a drainage study of the area. I cannot recall that anything every developed from this letter. I know that this study was not done under the Phase II & III Park design contract. I'd certainly like the opportunity of doing a study along the lines of the attached letter for the City of Renton. Looking forward to the possibility of working with you, I remain Sincerely yours, Michael H. Yuhl, P. E. MHY:c Enclosure f RI .�944 , Flow z October r` Mr. Jack Wilson, P. E. City Engineer City of Renton City Hall Cedar River Park Renton, Washington 960SS Dear Mr. Wilson: As you are aware, the rapid industrial development within the North Renton area is producing some serious drainage problems. The stores of moderate intensity which we have experienced this past summer have produced some minor flooding within Boeing's parking area and Puget Power's Ehuffelton Plant. The Parks and Recreation Department is planning to proceed with the deslgp of additional improvements at the Lake Washington Beach Park. Some of these Improvements will involve facilities adjacent to or In the existing creek. ORB is faced with a dilemme however, as in order to correctly size the proposed now downstream culvert, a design flow for a specified return period is needed. Although we can arrive at this flow by means of the rational method, many of the factors which enter the equation would need to be conservatively estimated. The elevation affects all upstream facilities as well as the placement of all future culverts. In a conduit In this range, excess capacity would be fairly costly. In order to properly design this conduit for a 40 yr. + service life, a rather extensive study of the entire drainage basin would be necessary to- gether with a study of the inter-relations of the existing drainage culverts. Puget Sound Power and light has recently relocated two culverts adjacent to the park. The required size and slope inverts and locations were arrived at by rather imprecise methods due to lack of a definite plan to guide their recon- struction program. ORB would like to discuss with you the possibility of provid- ing certain consulting services which would assist the City In providing an overall csomprehensive drainage study of this area. It Is believed that a properly conducted comprehensive study of this nature would Involve the following items: 1) An inventory of all existing facilities together with an assessment of the structural and hydraulic conditions of these facilities . we understand that your staff has already started this basic and necessary step. 2) A determination of the drainage basin area. r (r' To: Mr. Jack Wilson, P. E. " City Engineer City of Renton October 4, 10,68 -2- 3) A calculated time of concentration together with field studies to substantiate this time for various points within the drainage basin. 4) A study of the drainage basin in order to evaluate the existing surface conditions which would affect the runoff coefficient. 5) A review of existing zoning to assess the future or ultimate develop- ment of the area as it relates to the runoff coefficient . 6) A field study to determine existing stream flows during storms of measured duration and intensity. (This would permit better correlation of the estimated runoff coefficients and the time of concentration with actual flows and hence would allow a statistically more reliable pro- jection to storm flows of a longer return frequency.) The foregoing steps involve essentially gathering the information necessary to define the scope of the problem. The subsequent analysis of the information would permit a prediction of the hydraulic and energy gradients for various storm return periods throughout the existing drainage system. ORB believes that much of this Information could be gathered by either your staff or Park Department staff during periods when their other duties would permit. Once this analysis was complete, ORS would utilize the results to define the relative magnitude of the problems within the system and recommend various improvements. The latter part of this study would consist of estimating the cost of the Improve- ments and then rating the various improvements in order of the cost to benefit ratio. We feel that a study of this nature would be extremely important in providing an orderly plan of improvements and betterments within the area. Sincerely yours, OLSON-RICHERT-BIGNOLD Michael H.

MEMORANDUM SUNSET BLVD NE (UAB) PROJECT Review of CR2Mletter of December 23, 1971 indicates certain items may need clarification and discussion relative to our original dis- cussion on the hydraulic study. We sug6est preliminary analysis be made of the five, ten, and twenty-five year flood conditions. We request recoi=endations on sizing relative to the weak areas in the system. We request identification of weak or problem areas in the system based on the information we provide . We desire reco,.Yutiendations of the correction for outfall condition from Lake Washington Boulevard outfalls ( south side ) to Lake Washington. Request has been made for contours of the drainage channel, which we do not have and at present have not ordered for this phase of the activity. We were under the impression that the hydro proCram you have and information available could. provide the information of outfall data at the lake Washington Boulevard location. We request a discussion period on this portion of the work on or about Tuesday, January 11, to clarify this item prior to proceeding further on the computer activities. We see no reason to spend $1500 for information which may not be directed at solving our outfall problem. Discussion with Bill O'Dell indicates our specific needs may not have been sufficiently clarified to Mr. Peyser to provide a successful project . By way of restatement, our needs are as follows : (1) Extent of flow to Lake Washington outfall (2) Corrections necessary and impro7ements needed from the outfall points just south. of Lako Washington Boulevard to the lake front. (3) Isolation of problem areas upstream and consideration for possible storage areas upstream.
