Rezone: E & H Council President Keolker-Wheeler presented a Committee of the Whole Properties, R-016-87 report indicating status of mitigation elements related to the E & H Properties projects in North Renton. The Public Works Director presented a matrix identifying and describing the status of the mitigation requirements imposed on the Garden Plaza and Park Plaza developments. The presentation was informational in nature requiring no action from Council. The report noted for the record that the matrix developed by The Blaylock Company, representing E & H Properties, failed to indicate that all mitigation measures related to these projects must be complete and operational prior to occupancy of the facilities. Since Council required that all mitigation programs be operational prior to occupancy, it is appropriate to reiterate Council's direction to the Administration that no deferrals or waivers should be allowed for development improvements without formal review and approval by Council.

Utility Supervisor Storm and Waste Water Utility Section City of Renton 200 Mill Avenue South Renton, WA 98055 Re: Springbrook Creek Interlocal Agreement Dear Mr sons: As we discussed in our telephone conversation on July 30, 1991 , new issues have arisen regarding fish passage/mitigation on the North Fork Springbrook Creek Regional Bypass Pipeline. King County Surface Water Management Division is willing to increase the total project funding from our previ- ously agreed to amount of $162,550 each, to $186,000 each. The new total for the project will become $372,000, allowing approximately $47,000 in added funds for potential fisheries mitigation. Thank you for agreeing to work this change in the agreement through your process. Addressing the change now, during the agreement authorization process, is difficult but more preferable to King County than the alterna- tive of trying to process an amendment to cover an increase in project costs at a later date. I appreciate your interest in getting the project underway and your willingness to cooperate. I am enclosing the edited agreement showing the new totals for the project. The project description language already encompasses any required fisheries work so this should be the only change. As you confirmed over the telephone, the time allowed for project construction appears to be suffi- cient at two years from the effective date of the agreement or when the project is completed. I am planning to walk our conveyance packet through the King County system in an effort to get the agreement on the agenda for the August 14, 1991 , Public Works and Transportation Committee of the Council . If the Council acts on the motion on August 19, 1991 as planned, we will have an author- ized agreement by August 20, 1991. Mr. Randall Parsons August 1 , 1991 Page 2 Thank you again for agreeing to work this change through your process. I am enclosing six copies of the agreement for your convenience. Please call me at 296-8304 if you have questions, need more information or there is anything else I can do to assist your process.

Current budget does not include from private developer costs) contingency or possible fisheries mitigation measure costs.) Summary of Action: The purpose of the interlocal agreement with King County is to provide for the continued cooperative management and joint funding of the design, right-of-way, acquisition and construction of a drainage improvement project, known as the North Fork Springbrook Creek Regional Bypass Pipeline Project. This interlocal agreement replaces the original interlocal agreement entered into in June of 1988, which expired at the end of 1990. By conveying drainage through the steep and highly erodible section of channel at the headwaters of the North Fork of Springbrook Creek the project will reduce channel erosion, downstream sedimentation, and flooding that has caused property damage in the past. (See attached Exhibits for additional information). Due to the need for revisions and changed conditions since endorsing the original agreement, King County requested that the new interlocal agreement be endorsed rather than amending the original. The delay in presenting this new interlocal agreement for endorsement is due to County and the City staffs review -ind negotiations on its contents. STAFF RECOMMENDATION: Staff recommends Council passage of a resolution authorizing the Mayor and City Clerk to sign an interlocal agreement with King County to implement the North Fork Springbrook Creek Bypass Pipeline Project. northfrk/RS/bh ' J 1 CITY OF RENTON MEMORANDUM DATE: July 22 1991 TO: Kathy Keolker-Wheeler, Chair Members of Utilities Committee VIA: Earl Clymer, Mayor FROM: Joa G ann, Administrator t t of Planning/Building/Public Works STAFF CONTACTS: ll Parsons, Storm and Wastewater Utility Supervisor SUBJECT: Issue Paper - North Fork Springbrook Creek Regional Bypass Pipeline Resolution for Project Interlocal Agreement RECOMMENDATION: The Stormwater and Wastewater Utility Section of the Utility Systems Division recommends the passage of a resolution authorizing the Mayor and City Clerk to sign an interlocal agreement with King County that will allow for the continued joint funding of the design, right-of-way acquisition and construction of the North Fork Springbrook Creek Bypass Pipeline project. BACKGROUND: In 1988, the City of Renton and King County entered into an interlocal agreement to fund the design, right-of-way acquisition and construction, of drainage improvements which would prevent further erosion and flooding damage in the Springbrook Creek Watershed. Due to the revisions and changed conditions since endorsing the original interlocal agreement, King County requested that a new interlocal agreement be endorsed rather than amending the original. This project responds to and is named for implementation in the proposed settlement of the current litigation filed against King County and the City of Renton by Mr. Don Gallagher, owner of the Springbrook Trout Farm. This litigation resulted from damages to Mr. Gallagher's property due to the severe erosion and sedimentation generated by runoff during the January, 1990 storm event. The litigation calls for King County and the City of Renton to proceed as fast as possible to implement this project in order to reduce the potential for additional damage to Mr. Gallagher's property. Kathy Keolker-Wheeler, Chair Members of Utilities Committee July 22, 1991 Page Two King County has completed the design of the North Fork Springbrook Creek Regional Bypass Pipeline project. The City is in the process of completing the environmental and permitting requirements for the project. Construction on the project could start later this summer depending on all required permits being obtained and environmental concerns satisfied. The City assisted in the design phase of the project by providing survey, geotechnical information and design review. The City of Renton will take over ownership of the project following construction and will assume maintenance responsibilities for the facilities. DISCUSSION: The project is designed to reduce erosion and channel sedimentation that is occurring in the head waters of the North Fork of Springbrook Creek located in the Renton Watershed. The erosion and channel sedimentation has resulted in significant property damage during storm events of 10 years and larger over the last 20 years. The flows from King County enter the North Fork of Springbrook Creek located in the northeastern portion of the City of Renton Watershed. The ground slope is relatively steep in this portion of the watershed and also contains highly erodible soils. During storm events the velocity of the surface water flow in the channel causes the soils to erode and carry the sediment and debris downstream where it is deposited in lower gradient sections of the channel. This results in the plugging of road crossing culverts and filling in of the natural channel. The plugging of culvert crossings and the deposition of sediment in the channel cause water in the creek to back-up and overflow its banks which results in flood damage to public and private property. The purpose of this project is to convey the surface water flows through the steep and erodible section of the stream by a continuously welded high density polyethylene pipe which will outlet into an energy dissipation structure. The velocity of the flow leaving the energy dissipator will be greatly reduced which will help prevent erosion and sedimentation of the channel. CITY OF RENTON, WASHINGTON RESOLUTION NO.

Originally the County had proposed amending the original interlocal agreement to extend the duration (it expired December 31 st, 1990), but they changed their minds due the substantial errors and inconsistencies in the original interlocal agreement. Yesterday was the final day for comment on our Determination of Non-Significance (DNS)for this project. Enclosed you will note that Mr. Edwin Cleveland,the property owner adjacent to the west side of Talbot Road and south of the Springbrook Trout Farm (Gallagher) property, has appealed this determination to our Hearing Examiner on the grounds that the project will further adversely impact his property. The Hearing Examiner has requested that Mr. Cleveland provide additional description for the basis for his appeal within one week, prior to ruling whether the appeal is valid. If the appeal is ruled to be valid a public hearing will be scheduled likely in the later part of August. The Hearing Examiner will rule on whether the appellants' concerns are valid and may reject the DNS or impose mitigating conditions. If the appellant remains unsatisfied by this hearing, he will have two additional weeks in which to request the Hearing Examiner to reconsider. If following this two week time period the appellant remains unsatisfied he may take the matter before the King County Superior Court. In this case, it seems reasonable that we could request the Court to require the appellant to post a substantial bond from potential damages due to the delay of the project. If we are unsatisfied with the Hearing Examiner's decision, it is our understanding that we can appeal to the City Council to consider over-ruling his decision. We are currently awaiting resolution by King County staff of issues raised by the Washington State Department of Fisheries in their review of our Hydraulic Project Approval Application. If these issues can be resolved soon it seems that we still may have an opportunity to ad this project for proposed construction into this fall (The Fisheries habitat manager has indicated that she may authorize a construction window through November). Page 2: North Fork Springbrook Creek Regional Bypass Pipeline, July 10, 1991 We will appreciate your timely review of the interlocal agreement and preparation of the required resolution for consideration by the Council to authorize the Mayor to endorse the interlocal agreement. Please call me at 277-5548 should you have any questions regarding the project or the agreements I will be gone Friday, July 12th and will return on Tuesday July 16th.

Since I am forwarding the agreement to the King County Prosecuting Attorney' s Office (PAO) for review at the same time it goes to you, there may be changes from both reviews. The agreement has some new items in it. The total project expenditure of $325,100 reflects the revised cost breakdown I received from Doug Chin this week. Other changes, such as the project name change, specific location, and some of the responsibilities, reflect comments from your letter to me, dated January 25, 1991. If we can both get this reviewed quickly, we can get it started on its way through the system. With the King County Council ' s full agenda, approval of the authorizing motion may take a while so it is best to get it moving as soon as possible. If you have questions, comments or need more information, please call me at 296-6519. Thanks for your help on this.

RE: Springbrook Creek Interlocal Agreement Amendment Dear Randall : A draft amendment to the 1988 interlocal agreement between King County and Renton to design and construct the Springbrook Creek drainage facilities is enclosed with this letter. The amendment is necessary because the original agreement expires at the end of this year and the facility is not yet constructed. The proposed amendment redefines the project from a "facility" to a pipeline, increases the total project budget, and extends the agreement to December 31 , 1991 or when the project is built, whichever comes later. The budget or cost of the project is increased from $240,000 to $300,000, requiring each party to contribute an additional $30,000. These are the changes requested by Project Engineer Doug Chin. I will appreciate your review and comment on the changes. Because of the tight turnaround time, I am taking the liberty of enclosing four additional copies of the amendment in the chance that it will not need further changes. In that case, could you please have them all signed and return them to us for the Executive' s signature. If there are adjustments you wish, however, please let me know, we will make the changes and get copies back to you quickly. Thank you for your help and cooperation. Hope to see you soon.

References Sk q GENERAL t { The Springbrook Watershed is a 53 acre tract of property owned by the City of Renton and used by the City Water Department for eater supply. Location of the property and its vicinity is shown on r4ap 1 . Topography of the Watershed and vicinity is shown on Trap 2 . In general the tributary area upstream of the Watershed can be classed as gently rolling . The Watershed itself includes two relatively steep ravines , densely forested with mixed conifers and deciduous trees . In the newly platted resident- ! z 1 resident- ial areas surrounding the Watershed there are yard improve- ments .. �l) t but few trees . In general the soils are classified as the Alderwood series which consists of several inches of forest litter over a friable surface soil which in turn is i 3 underlain by a dense glacial drift soil. �l) At the Springbrook IVatershed itself the soils are classified t as rough broken and stony land. This type of material char- R acteristically occupies the steep terrain along breaks , a 3 ravines and gullies . The soil is derived from the adjacent a upland soils . p� t , a , 1. 0 1 ' i 1 , During and after heavy rainstorms on February 27 and 28 , 1972 considerable flood damage occurred at the Springbrook Ivatershed. The actual damage has been carefully documented by the City of Renton by reports and photographs . Classif- ication and extent of damage is not included in this Report . The references made in this Report to photograph numbers refer to the City of Renton ' s file of numbered damage photo- graphs . FINDINGS Certain flood damage occurred at the Springbrook '►•Jatershed during the rainstorms of February 27th and 28th, 1972 . The basic problem involved heavy rainfall during a storm that later was classed as a "2S year frequency" storm. The re- sulting runoff substantially saturated all available around i in the vicinity of S. E. 200th Street and 102nd Avenue S. E. i The extremely heavy runoff was caused by the heavy rainfall and was compounded by two other factors . Land development t 2 ' 1 .1 f P In the area had reduced the ability of the ground to absorb water by covering lar0e areas with paving and structures . C. Cl This caused runoff to be more rapid and consequently larger . Secondly in two cases storm water was partially diverted from natural water courses . Our investigation consisted of field work, conversations with adjacent property owners , and office computations . The investigation utilized field survey work as well as detailed rainfall intensity data secured from the National Climatic Center at Asheville , North Carolina - See Appendix 1 The investigation is divided into four units : 1 . Natural Causes 2 . Diversions from Natural Drainage 3. Runoff problems within the Watershed 0 4 . Hydraulic Computations a 1 . Natural Causes The surface soil in the upland drainage area is classified (1) under the Alderwood series . In the USDA soil survey the drainage characteristics were noted as follows : "Surface drainage is sufficient , however, internal movement is great- ly retarded by the cemented substratum. Waterlogging fre- . 3.- F fluently occurs at the surface of the indurated material in Winter and early Spring . " Tree roots mat horizontally due to the hardness of the substratum and generally pone- E tration is restricted to 3 feet . The permeability o the f 1 soil ranges from 0 . 63 to 2 . 0 inches of hater per hour as noted in a recent USDA study. The foregoing items coupled with the heavy rainfall involved provided a saturated con rainage area. When a High intensity dition throughout the d rainfall occurred on February 28 the resulting extremely high runoff caused considerable damage in the watershed. 2. Diversions from Natural Drainage The basic problem area involved was at Point 1 shown on y Map 2 . Heavy flows of storm water from the residential areas lying Southeasterly resulted in water bypassing the intended drain point - the storm manhole at Point 1 . The existing roadway cross sections showed that storm flows by- passed the manhole and proceeded both across S. E . 200th Street and Westerly on thru the grade break. Photos 15 16 showed that a substantial flow bypassed the b1H and flow- ed Westerly on the South side of S. E. 200th Street . Photos and survey data also verified that this flow was di- t a { 4.• vested to the North side of S. F.. 200th Street at approx- mately Survey Station 4 + 10 . 'Phis flow ultimately arrived at Pt. 2 removing considerahle gravel from the North shoulder of S. E. 200th Street and leaving it spread on the adjacent field. The water then flowed Northerly overland into the Watershed causing severe damage. When the Springbrook school was opened, 100th Avenue S. E. was protected by placing ditch- ing and culverting on the hest side of the then existing gravel road between S . E. 200th Street and the South property line . At soine point in time storm water flow was diverted Northerly from areas normally draining Westerly at S . E . 204th Street and 100th Avenue S. E. A portion of this diverted flow from the residential area lying S. E . of the intersection also found its way to Point 2 by the new ditch and culverting in the West side of 100th avenue S . E. The storm water cascading Westerly down the hill along S. E. 200th Street and all the water from the South concentrated at Point 2 . The flow con- centration was so great that it physically removed the surface soil causing large and small trees to topple in the forested t area lying above the dam on the Watershed property. See Photos 22 and 29. The soil removed was washed down the creek and 5 . completely filled the .first catchment dam. See Photos before and after. (2 and 46) Once the catchment dam was full all further debris was trapped by the main dam. See Appendix 3 for approximate chronology of events. 3. Runoff within the Watershed The Springbrook Watershed is a 53 acre tract used by the Renton Water Department as a water supply collection area. The water system improvements existing prior to February 1972 included; the upper collector dams , connecting culverts , lower dam, supply pipelines and chlorinator station. The upper collector dams are concrete cut off walls which confine and collect both surface and underground water. The lower dam is .earthfill with a reinforced concrete face . The dam also intercepts and collects both surface and under- ground water and in addition provides an estimated half million gallons of water storage. The dam has an overflow which protects the dam from being overtopped. When water rises above the level of the over- flow weir it will be diverted through two 12" pipes back to the downstream stream bed. The weir has an overflow capacity of approximately 17 cfs . The top of the dam is approximately 6.. • s 3 feet higher than the weir top and this in turn represents x zpprux-LhlUtely 36 , 000 cubic feet of water storage available r before overtopping; will occur. The effect of the dam is to t provide holding capacity for short duration high runoff and this then reduces the peak flows downstream of the dare. The average rate of discharge of crater into the City water system is 2 NIGD. (3 cfs) 4 . Hydraulic Computations a See Appendix 2 3 i t 7• • SS t f CONCI.US [ONS F ' f t 1 . The extremely high runoEF in the area was caused by: a) Extremely high precipitation as shown in .Appendix 2 b) Permeability and retentive capacity of the soil has been reduced by land development causing a more p rapid runoff. c) At the time of peal: rainfall the permeability and retentive capacity of the soil had been reduced by saturation of the soil by prior rainfall . d) Drainage structures have diverted flow from natural t drainage to Point 2 where it then entered the Water- i shed by overland flow. {s 2 . At the time of peak runoff an undetermined flow traveled 3 from Point 1 to Point 2 Westerly along and parallel to y to Street. This flow which is contrary S. E. 200th natural drainage occurred because the extremely high run- f t off concentrated at Point 1 was unable to flow Northerly into natural drainage clue to the restriction of a culvert 6 inlet structure . t i i 3. Damage in the 1`latershed was caused by the flow from a 8 1 r � • Point 2 which entered the Watershed by overland travel . . 4. Dariage to the Watershed would have been far less exten- sive if flow had not entered at Point 2 but instead had entered natural drainage at Point 1. S. The combined effect of the collector dams and the lower dam was to reduce the runoff in the natural stream below the Watershcd. The lower dam was not overtopped. The lower dam acted as a containment structure and prevented debris from .entering the natural stream. { 6 . During the period of high runoff fine suspended silt and debris was probably carried through the dam and out the overflow to the natural stream. This would have created a milky appearance in the stream. Y 7. Water which .is normally withdrawn into the City system was diverted into the stream due to the appearance of silt in the water. This diversion did not significantly contribute to the problem due to the relatively small volume in comparison to total runoff and also due to the fact that the diversion did not occur until 4 to S hours after time of peak flow. k } fi 9.. k r P � • With continuing development of land, rapid storm water runoff will continue to cause similar problems when heavy rainfall occurs . The most practical solution will. be: P 1) Careful design of storm facilities upstream of the watershed, coordinated with the City, so that run- off will remain in its natural drainage , or total 6 diversion of drainage to protect the watershed t from storm damage and polluted waters . { 2) The design of natural or artificial facilities which restore the water retentive qualities of the land. This will require the cooperation of prop- erty owners and the governmental agencies respons- ible for storm drainage planning . T } 6 t 10 S. E. 192 N*ST. I 1 a cI co ' rn s w / S.

Engineers from the King County Surface Water Management Division will describe possible improvements, answer questions, and listen to community concerns. They will present several options for reducing flooding and erosion in the vicinity of Southeast 200th Street and Talbot Road. Options include: -' increasing the size of the existing detention pond - increasing pipe capacities - piping flows through the eroding ravine, and - creating a sedimentation pond at the bottom of the ravine. Residences, and the City of Renton' s water supply reservoir, have experienced severe problems following major storms . The City of Renton will contribute to design and construction costs for the project, scheduled for construction in 1989. If you have any questions, please call Dave Carlton, Senior Engineer of the Project Management and Design Section, at 296-6586, or Jan Ostenson, Public Involvement Coordinator, at 296-6573.

Re: Springbrook Erosion North Fork Canyon Dear Mr. Price, This letter is a result of your September 13 meeting you called regarding the subject erosion problem. The question we believe that was asked of Lobruch was which method of erosion abatement does Lobruch prefer? Here is our answer. The potential for the erosion problems in the canyon now being encountered where known prior to the 1986 storm. Since the installation of the storm water diverting pipe from the Schneider home development in 1985, hundreds of years of erosion have occurred in only two short years. The invert of the creek bed has dropped six feet in some places since modification to the natural drainage. A native Douglas Fir, hundreds of years old stands precipitously close to falling into the deep creek bed formed from the accelerated erosion. This canyon is anticipated to be a park for a future planned development envisioned by Lobruch. It would be a tremendous amenity to a residential development as a park, play, or picnic area and a place of solitude. The solutions presented to rectify the erosion included: 1. Approximately 1300 feet of plastic pipe laid in the bottom of the creek bed. This pipe would transfer all water from the top to the bottom without going through the creek bed. 2 . Install channel made of gabion. 3 . Build a large holding reservoir at top of canyon and meter water out so that maximum flow is such that minimum erosion occurs. At the bottom, a siltation pond would be built. f 4 . Combination of the above solutions. The preferred solution to the erosion problem is #4 , a combination of the above. We would like a large pipe installed in the creek bottom adequate for future water flow including overflow from an 8 acre development on Lobruch property and anticipated runoff from an improved Benson highway. In addition, we see the following requirements necessary to reinstate this canyon area back to its pre-1986 condition: 1. The pipe should be covered with appropriate natural material to bring the creek bed back up to its pre-1986 elevation. 2 . The Old Fir should be propped up and filled around so that it remains standing. 3 . Annual inspections should be done by both the City and County. 4 . City and County assumes full responsibility and liability for the water flow through the drainage basin as well as maintenance and operation. 5. An effort will be made to minimize disturbing the land during construction and long term maintenance and operations. 6. The natural barriers and boundaries should be established again after construction. Your consideration of this solution would be most appreciated. Time is of the essence in this negotiation and an expedient commitment is necessary on your part. Sincerely, ,V�� J� Charlotte Ann Cline President, Lobruch, Inc. cc: Charles E.

He noted Homes Detention Pond that a copy of a letter he sent to King County Executive Tim Hill on 12/15/87 outlining his concerns was transmitted to the Renton City Council early this year, and he understood that correspondence was sent to the City by the County Ombudsman as well. In addition, Mr. Goldmann claimed that vegetation on his property was damaged recently by persons employed by Renton to perform a surface water drainage study. Councilwoman Mathews recalled that no action was taken on Mr. Goldmann's letter since it was addressed to King County regarding a County project, and she reported suggesting to Mr. Goldmann a year or more ago that he contact King County and file a claim with the City of Renton regarding this matter. MOVED BY REED, SECONDED BY KEOLKER, COUNCIL REFER THIS MATTER TO THE ADMINISTRATION FOR INVESTIGATION AND REPORT BACK TO COUNCIL. CARRIED. Advancement to Jeff Lukins, 1113 S. 23rd Street, Renton, Victoria Hills Homeowners' Correspondence Association President, requested advancement to Correspondence item 9.c. MOVED BY REED, SECONDED BY KEOLKER, COUNCIL SUSPEND THE REGULAR ORDER OF BUSINESS AND ADVANCE TO CORRESPONDENCE ITEM 9.C. CARRIED. PUD: Final, Victoria Hills Letter was read from Building and Zoning Director Ronald G. Nelson Phase II, FPUD-042-85 requesting Council to set a public meeting on 2/22/88 to discuss proposed revisions to the Victoria Hills Phase II Final Planned Unit Development. Attached letter from developer Charles G. Spoerer III outlined objections by residents to Phase II traffic being routed through the existing neighborhood; location of buildings, service road, and off-street parking too close to property lines; and excessive height of four-story buildings near residences. In response to these concerns, Mr. Spoerer proposed relocating two of the buildings, the road and parking area, and studying whether the buildings could be reduced in height. By removing one unit from each of the 21 six-plex buildings, the project could be reduced from 196 units with 152 garage parking stalls to a 175 unit complex with one garage for each unit. The uncovered parking requirement could be reduced by 44 cars to allow necessary space to relocate the two buildings. Administrative Assistant Michael Parness explained the purpose of the public meeting to allow an exchange of information between the residents and the developer, and allow Council to determine whether proposed changes are sufficiently minor to allow modification of the approved FPUD rather than requiring the developer to reapply for a new PUD. Mr. Lukins charged that the developer may be proposing revisions to reduce the cost and scope of the development, rather than responding to residents' concerns; noted desire of homeowners' association to adopt a plan that would be acceptable to both sides; advised that traffic through the neighborhood remains the major problem and has not yet been resolved; questioned whether the revised plan is the same one previously rejected by homeowners because traffic was not addressed; and stated his opinion that if the latest plan is the same, it may constitute major rather than minor changes. Mr. Chuck Spoerer, 10220 NE Points Drive, Kirkland, agreed with Mr. Lukins that the primary problem with proposed Phase II is traffic generated through the existing neighborhood, but he explained that because access has been previously approved by the City, it is beyond his control. He clarified that new plans are not the ones previously reviewed by residents. MOVED BY HUGHES, SECONDED BY KEOLKER, COUNCIL SET A PUBLIC MEETING ON FEBRUARY 22, 1988, TO CONSIDER PROPOSED REVISIONS TO THE VICTORIA HILLS FPUD. Councilman Stredicke requested that prior to the public meeting, copies of original, modified and proposed plans be available for review by Council members and citizens. MOTION CARRIED.
