PROJECT OVERVIEW The total site area, including improvements to adjacent roadways, is approximately 16.19 acres. The project site is located within a portion of Section 3, Township 23 North, Range 5 East, Willamette Meridian, King County, Washington. More particulazly, the site is located north of SR-900, west of 148th Avenue S.E., and has the approximate street designation known as S.E. 107th Place. Please see the attached Figure 2 — Vicinity Map for an exact location of the project site. There are several existing buildings located in the southeast portion of the project site and appropriate drive aisles, driveways, parking areas, and landscaping all under pre-developed conditions. The remainder of the site consists of fairly irregularly sloped ground consisting chiefly of brush and trees, which tends to slope towards the center of the project site in a northerly direction. One of the tributaries to May Creek passes through the center of the site and is considered a seasonal stream and consists of a small svip of wetland area with a buffer that will remain undisturbed with the development of this project. Slopes on the project range from 2 percent up to 30 percent. In addition to the on-site acreage there are improvements proposed for the SR-900 and 148th Avenue S.E. intersection in the form of road improvements consisting of chiefly 0.25 acres of new impervious surface. There are 58 lots proposed with this phase of the development. An additional 8 to 13 more lots aze proposed for the southwest corner of the project site. The site tends to slope in a northerly direction for the most part. There are well over 100 acres contributing runoff to the project site. This upstream basin of more than 100 acres is partially developed with existing single-family residences, a schoolyard, some wetland areas, and undeveloped areas as well consisting of trees and brush; however, for the most part the upstream basin is mostly developed. The proposal for this development is to construct the lots and adjoining streets with catch basin collection and pipe conveyance systems all draining into a centrally located wet/detention pond that will perform water quality as well as flow control, meeting the requirements of King County as well as the City of Renton, which has adopted the 1998 King County Surface Water Design Manual. The requirements for this project site are to provide Basic Water Quality and Level 3 Flow Control due to downstream problems. Please refer to the Section 3.0 Off-Site Analysis for a complete description of the downstream drainage course and problems associated with it. ; � I � 11189.00l.doc[JPJ/dcn/tep] II I— FIGURE 1 TECHNICAL INFORMATION REPORT (TIR) WORKSHEET ' King County Department of Development and Environmentai Services I TECHNICAL INFORMATION REPORT (TIR) WORKSHEET Part 1 PROJECT OWNER AND PROJECT ENGINEER Part 2 PROJECT LOCATION AND DESCRIPTION Project Owner KBS III,LLC Project Name Address 12320 N.E. 8th Street, Suite 100 Stonerid e Bellevue,WA 98005 Location Phone Township 23 North Project Engineer Ali Sadr Range 5 East Company Bar hausen Consultin En ineers, Inc.

Response: This project is proposing to discharge to the same seasonal stream it currently dces under existing conditions. However, runoff may be modified somewhat with the development of this site splitting flows somewhat between the two streams that drain through the project site in a different fashion than it currently does under existing conditions. The site will still drain to the same stream downstream though. Core Requirement No. 2: Off-Site Analysis. Response: This project should not have to provide an off-site analysis due to the fact that Leve13 Flow Control is required, which is the most severe flow control required for projects that contribute to areas prone to flooding. The off-site analysis wouId provide no more determination of required flow control above that; however, an off-site analysis is provided herewith with this project in Section 3.0 Off-Site Analysis of this Technical Information Report for a review. Core Requirement No. 3: Flow Control. Response: In accordance with the requirements of the City of Renton and King County, Leve13 Flow Control is proposed for this development and will be instituted with the final construction of the plat. Core Requirement No. 4: Conveyance System. Response: In accordance with the 1998 King County Surface Water Design Manual and since the project site consists of over 10 acres of new development, an SCS-based hydrograph methodology of computing runoff to each catch basin may be instituted in the design of the conveyance system draining to the wet/detention pond located in the central portion of the project site. In addition, the culvert draining underneath 148th Avenue S.E. that contributes runoff to the northeast portion of the project site will be analyzed based on the Santa Barbara Urban Hydrograph (SBtTH)methodology, which is an SCS-based methodology of computing runoff. Core Requirement No. S: Erosion and Sediment Control. Response: This project will prevent the transport of sediment to streams, wetlands, lakes, drainage system, and adjacent properties through the institution of carrying limits, cover measures, perimeter protection, traffic area stabilization, sediment retention, and surface water controls, all in accordance with Appendix D of the 1998 King County Surface Water Design Manual as adopted by the City of Renton. Core Requirement No. 6: Maintenance of Operations. Response: The drainage facilities on this property will be maintained by the City of Renton and any maintenance and operations requirements of the City will be instituted into the Final Technical Information Report prepared for this development. 11189.00l.dce[JPJ/dm/tep] Core Requirement No. 7: Financial Guarantees and Liabiliry. Response: Any financial guarantees and liability required by the City of Renton will be followed and maintained by this project prior to construction. Core Reguirement No. 8: Water Qualih�. Response: The City of Renton and King County have already indicated that Basic Water Quality is the required water quality methodology for this project, which is being provided in the form of a wet pond located below the live storage in the �vetldetention pond in the north central portion of the project. Analysis of the Five Special Requirements: Special Requirement No. 1: OtherAdopted Arece-Specific Re�jl�ire�r�e�its.

Special Requirement No. 4: Source Controls. Response: Source controls will be provided with this development in accordance with the 1998 King County Stormwater Pollution Control Manual and King County Code Section 9.12 for a multifamily development. Speeial Requirement No. S: Oil Control. Response: This project dces aot meet the requirements of a high-use site nor is it a redevelopment project;therefore,the requirement of oil control is not required for this site. The following pages of the report delineate the Stoneridge Plat final plat requirements as dictated by the City of Renton in a letter to Curtis G. Schuster dated July 24, 2003.

Upon annexation by the City of Renron, the final plat must be approved by Renton. It is our intent to require compliance «�ith the conditions of the preliminary plat where practical, and to reqnire eonformance �vith the intent of conditions that cannot be met exactly as worded. The following is a list of the King County Nearing Examiner conditions of the preliminary plat approval, along with the Renton reqoirement for comp)iance with each condition for final plat approval. l. Compliance "�ith all platting provisions of Title 19 of the King County Code. Renton Requireinent: The applicant shall complete the plat required street, utility and drainage I improvements per the approved preliminary plat. The applicant shall comply with the requirements of the Renton Subdivision Regulations for final plat approval procedores. 2 All persons having an o��mership interest in the subject property shall sign on the face of the final plat a dedication that includes the language set forth in King County Council Motion No_ 5952. Renton Requirement: The applicant shall comply with the requirements of the Renton Subdivision Regulations for final plat approval procedures. 3. The plat shaJl comply �vith the base density and minimum de�sity of the R-4 zone classification. All lots shal} meet the minimum dimensional requirements of the R4 zone classification or shall be generally as shown on the face of the approved preliminary plat,except that minor revisions to the plat that do not result in substantia) changes may be approved at the discretion of the Department of Development and Environmental Services. Any changes to the plat design which are mandated by the conditions ��hich follo�v shall also be permitted. Renton Requirement: The applicant shall comply ��ith the condition as written for density and dimension requirements. The app}icant shall provide a copy of the R-4 zone dimensional requirements with the final plat application.

The project is located within a poRion of Section 3, Township 23 North, Range 5 East, Willamette Meridian, King County,Washington. More specifically, the site is located on the west side of 148th Avenue S.E. north of SR-900 and covers the existing S.E. 107th Place roadway serving existing lots. The enclosed Exhibit A — Vicinity Map depicts the approximate location of the proposed site. The existing topography of the site is such that there are slopes ranging from 2 percent up to 30 percent draining in a northerly direction for the most part, with upstream basins contributing runoff from the east, south, and west. The southeast portion of the project site is currently partially developed with existing single-family residences and buildings with drive aisles, landscaping, and associated improvements at that location. The remainder of the site is mostly forested or pasture with thick brush,which will be cleared with this development. The proposal for this development is to construct 58 lots with appropriate streets, sidewalks, stormwater collection and conveyance facilities,as well as a weddetention pond sized for Level 3 Flow Control in the north-central portion of the project site. Access to the site will be off of 148th Avenue S.E. There are two seasonal streams contributing runoff to the project site, one from the south and one from the east ' from underneath 148th Avenue S.E. These streams join up to become Green Creek, which is a tributary to May Creek and this project site drains to Green Creek. The two seasonal streams drain through II wetland areas that will be preserved with the development of this project site. � UPSTREAM DRAINAGE ANALYSIS I Based on the USGS Quad Map, our site visit, and ]rnowledge of the property, there aze two seasonal I streams that have runoff contributing from upstream flowing through the site. These upstream basins consist of well over 100 acres of partially developed land. There are also existing wetlands in the ' upstream basin as well as pasture and forested areas. The impervious surface in the upstream basin is approximately 3 to 5 percent.

It is not known if a Basin Reconnaissance Summary Report has been prepared for this basin as of the writing of this report;however, we do not have a copy on file in our office. • Critical Drainage Area Maps: The City of Renton and King County have already indicated that Basic Water Quality and Level 3 Flow Control will be the means of water quality treatment and detention proposed for this development. • Floodplain and Floodivay FEMA Maps: Please see the enclosed E�chibit D—FEMA Map utilized for this analysis, Panel No. 6b9 of 1,725, Map No. 53033C0669 F, revised May 16, 1995. As indicated by this map,the proposed project site dces not lie within a floodplain or a floodway of a stream; however, it is known that two seasonal streams pass through the site, which will be conveyed through the site under developed conditions as well. They are much lower in elevation that the proposed lot elevations by over 10 feet. • Other Off-Site Analysis Reports: A review of the United States Department of Agriculture Soils Conservation Service Map was performed with this analysis. • Sensitive Areas Folios: Based on our review of the King County Sensitive Areas Map Folios, it was found the subject site has a Class III stream passing through it and the areas contributing to it are mapped wedands as well as the downstream drainage course from the project site. In addition, there are known wetlands located within the seasonal stream locations on site. Those are the only known sensitive areas as indicated by the Sensitive Areas Map Folios. • Road Drainage Problems: This is not applicable. • United States Department of Agriculture King County Soils Survey: Based on the soils survey for this portion of King County, the entire downstream drainage course and the entire site occurs through Alderwood type soils until entering May Creek where the soils are a Ragnar-Indianola Association. • Wetland Inventory Map: The Wetland Inventory Map for this area is included herewith. See the exhibit within this section of the report indicating May Creek Wetland 6, which is located on the south side of SR-900,of which drainage from this wetland contributes to the project site. • Migrating River Studies: This is not applicable. 11189_003.doc[JPJ/dm] A � � � � � � � � W W w To determine if flood insurance is available,contact an insurence agent or call the National Flood Insurance Program at 1,8001635-6620.

I WETLAND EVALUATION SUMMARY: Data was collected in the five categories shown below. Within each category the data was evaluated to produce numerical values. Composite values for each category vrere produced in order to compare exh wetland to other wetlands in its sub-basin and in King County. The result of that comparison was a percentile ra�k. The percentile is expressed on a scale of one hundred and indiptes the percent of wetlands tfiat scored equal to or below that particul�site. For example,a percentile renk of SO under wb�asin means that the wetland scored equal to or better than 80 percent of all sites within the wb-basin for that evaluation category.NOTE: The percentile ranks are valid only within the individual evaluation category and are intended solely tor reference and comparison. Rank Evaluation Category . (by percentile) Sub-basin County-wide Hyd�OlOgy: runoff storage potential,water quality,potential for minimizing damage 64 82 in downstream areas BlolOgy: quality of habitat,abundance and diversity of plant and animal species 2i 25 Visuel: diversity and contrast of wetla�d and surrounding vegetation, 35 3!1 surrounding landforms Cultural: types of access,proximity to schools/institutions,overell 50 56 environmental quality EConOmIC: presence of agriculture/peat extraction,anadromous or game fish, 35 25 game birds or mammals of commerciel value WETLAND RATING: ch wetland was assigned one of three possible wetland ratings. The wetland ratings were determined by examining the scores of selected ntory tasks, specific data or percentile ranks for individual evaluation categories. The criteria used to assign the wetland ratings are ribed in the Introduction. For each rating a number of specific guidelines fw new development in or adjacent to wetlands were prepared. The guidelines are intended to assist in carrying out King County's Sensitive Areas Ordinance and other wetland policies. They are included in a separate report titled"Guidelines for King County Wetlands".

Based on a review of the drainage complaints in the downstream drainage course, there was one property owner who has indicated that erosion is occurring on her property at several occurrences during major storm events in the last 15 years. In addition,that same property owner has indicated that flow rates contributing to the stream in her backyard are increasing as development occurs in the upstream basin. This property owner has written several letters to King County's various divisions including governmental offices requesting assistance with problems on her property. That is why Leve13 Flow Control is proposed for this development. Based on the drainage complaints and ow site visit, it appears flooding has not been a major problem in the downstream drainage course from the subject property; however, Level 3 Flow Control will be provided. The upper 5/6 of the do��nstream course courses through mostly backyards and brushy areas, until runoff enters May Creek on the far north end of the section. Most of the downstream drainage course investigated by this site visit and a review of the Soils Map indicate that the downstream drainage course occurs through Alderwood soils for the most part and then Ragnar-Indianola type soils near May Creek. The field reconnaissance for this off-site analysis drainage report was conducted on March 3, 2004. The skies �vere partly overcast and the hibh temperature on this day ��as approrimately 50 degrees. 1 llft9.(H)3 d<k[JPJIdm] TASK 4 DRAINAGE SYSTEM DESCRIPTION AND PROBLEM DESCRIPTIONS TASK 4 DRAINAGE SYSTEM DESCRIPTION AND PROBLEM DESCRIPTIONS Runoff leaves the site through the north-central portion of the project site and courses through backyard areas and vegetated swale consisting of wetland areas until coursing underneath S.E. 104th Street through a 30-inch corrugated metal pipe culvert. Flows continue in a northerly direction for the most part passing through backyards in a well-defined channel until flows pass undemeath 26th Street in the City of Renton, flowing north through 4.5-foot by 5-foot CMP arch culvert and then a little bit later the flow courses into May Creek. A review of the E�►ibit J — Drainage Complaints shows there is a one property owner that is very concerned about stormwater runoff surrounding her home. Many complaints were addressed by her from adjacent property owners. In addition the upstream drainage basin, which contributes runoff to the seasonal stream passing through her backyard, is the downstream drainage course from the project site. This property owner is the only complainant on the downstream drainage course from the project site, but she was complaining of erosion during peak flows contributing to an ongoing problem in her backyard. That is why Level 3 Flow Control is being instituted with this development. Please refer to the drainage complaints for a complete description of the problems associated with the downstream drainage course.

He has a one acre lot that he has cleared for,j�E construction of a home in the new year. Slope of the surrounding properties is from SE to NW, and neighbors to the south have dug an interceptor ditch across the back of their lot that is also said to drain another ditch from the next southerly neighbor. This had drained to an area on his lot that is proposed to be the foundation for his house. Mr Simon in turn dug a ditch along the property line to the ditch on 148th which he intends to tight line. BALD is said to have informed him drainage from the properties should go to the roadside ditch. Because the neighbors drained t� his property it is up to him to handle. At the time of observation there was drainage from the neighboring properties to Simon's southerly ditch, down the ditch to where it goes sub surface to a small pond in a low spot in the front, and from there to a cross culvert under 148th to a small swale. There was indication of some erosion from upstream due to siltation of the small swale. Followed the drainage to where it outlets west of 147th Av SE and observed no silt at that location. Pf�oto 1) Looks east from 148th across mid portion of the Simon property.

The stream tended to wander thru heavy brush and ferns and then culverted under 147th near 102nd Av SE. Where the stream crossed the ditch on the east side of 147th and at the outlet, there was no signs of silt. It appeared the silt was deposited on the property by the Dipple residence. At the time of the muddy water Mr Dipple feTt there v�ras a speed of run off at .2 cfs, whereas the run off normally flows at approx .02 cfs. At the time of observation run off was clear.

The roads are shoulder type with open ditches and x-tiles.There have been recent complaints regarding drainage that fiows to the lot being inquired upon by Ms Nagel. There appears to be a large area tF�at drains to the ditch on 148th upstream of the x-tile that drains towards the Nagel lot. Concerns had to do with quantity of water and siltation from clearing and construction. The x-culvert on 147th by the Nagel residence collects water from the drainage under 148th, the ditch on the south side of 102nd and west of 148th, plus some run off from the sloped area between 147th and 148th. The ditch draining to the x-culvert under 147th is grass lined and mowed, p�oviding a sodded ditch. Did not observe siltation or erosion in the ditch or at the outlet. There did not appear to be a disgnated stream as such at the outlet and thru the vacant lot, but there was a difference in vegetation coloration as if to identify moisture. Photo 11 Looks north on 148th from driveway leading to 10220. May Creek is just prior to end of road. 2) Looks south on 147th trom 102nd. x-tile is in first part of ditch. 3) Reverse view where x-tile is at hole lower right. 4) x-tile outlet is at buttercup line between two posts. 5) View of lot of interest by complainant. , �- � � , ketch: �`�a� . ,A� SE - � �— SE�otMQSt � t— •-- •--- �-- �� - --- � � - ��;_ . ��si�� Z,, � r � ,�, �� ,v,� � ,� � � � �i�'c�� .��. n �� f � I � i � /��' i � i� � Investigated by �j2 �/�„�,�f,�..., �� Date 7 -l3-f� I �.,c, L � K1NG COUNTY SURFACE WE4TFR,MANAGEMENT DIVISION . � � ' DRAINAGE INVESTIGATION REPORT Page 1: INVESTIGATION�REQUEST Type__� `I �ceived by: � � Date: S / _ S OK'd by: Fue No. q5- o yza s�� - ReCeic';:�1 fiom: (Please print plainly for scannin9)• (QaY� (Eve) � NAME: �'J�1 u�{ � �a�e�1 c L � PHONE v?SS- �.�4 D ADDRESS: �D��S� ��7f/� ,/V!/C Sc City /�c-�O� State�� Zip /�'�CI� Location of problem, ff different: Reporfed Problem: CL.4-SS �- S�.eE�l/1% �2t✓c�-Sc=S �prs'/O��aJ/l�/Ts /��.oPz��r� ��i�� /S ��/c��JG/�JS- Sc%xt= �i2�� ♦vc� /�c�t/S cs'� D� CJ��/G L �t��Z d P✓i7b-�(/�f wl�l�i � ��= �G s✓c T S�fi't�/G/�� C►�i/�J,f/EL ? �vuTv XI3S/SZ4R'Gar � � ��c �-� ` � s�� i✓�oT ,��,i� �,�N�2 r -r,�� /t/��C f�d.e .

' complaint 95-0420 DONNEI.Y, CLAUDIA Investigated by Doug Dobkins on 5-3-95 Meet with Claudia Donnelly and her husband at their home at 10415 147th ave southeast. The Donnelly's aze concerned about the small creek that runs through their property. A class III stream runs along their west propertY 1in0. Mr.Donnelly thinks that upstream development is causing some erosion amd saturating their properiy. I took Mr. Donnely on a tour of the area to show lum what is draining towards his property. There is no new development_ upstream of their property. The drainage basin consist mostly of grass and pasture. Most of the houses are iocated on large grassy lots or on 5 acre tracts. After driving the area with Mr.Donnely I didn't see any violations or problems in this area with the drainage. The Donnel}y's live in a low area were water collects in a small channel and drains to May Creek. The other concern of the Donnelly's is a new plat that is going in on the north side of their property. This plat is actuall located in the Ci of Renton. There is a outlett ditch on the northside of the neighbor to he northwest wluch even y drains to May Creek. The Donnely's want to know if this water is being aa:ounted for by the New Plat of . I said I would check into this for them. I explained that the county has no authority over this plat but I would check on the plans. � Cec awss m srxrwM ;.,,,.. ;::,. ..... .......,,.:.:::...... ............. r.••.:,�:�. ,...... ........:.�:::::.�::.-:...... ..:..:.........:..:........:. v','x"':'r":.............t4�+�"5:,:' ...... .................................................."'"...:::::::::::::iiiii:::....... ............................................................................ ..... ......""""".............................. ...........

Dear County Executive Sims: It has been two weeks since I sent you my first letter_ I haven't heard back from eith��7_Q you or any one else, so I figured i'd write again. I made a r�py of the video tape of Greenes Stream from March 19, 1997 and need to know if 1 should send it to you or someone else. Severaf years ago, when Gary Locke was County Executive, I wrote to Mr. Locke about our problem at ihat time. Some County people came out and took a look at our stream/neighborhood probfem. 1 also received a letter from him . . . Please advise me if i shoufd sent the tape to your office or to someone else's office for viewing. Would it also be possible to get an apology from David St_ John? To have him tell me that the County doesn`t care abaut us -- we'll only be annexed or incorporated in the future -- Is that the attitude of all County employees about us? Like I said, we are only 3 houses, but our property is being destroyed and no one seems to care. We also pay taxes like everyone else. Since we've been told that the County won't fix the culvert allowing water to flow underneath 148th Avenue SE to Greenes Stream, h�w are we to protect our properry from future flooding that will only be getting worse? Just ignore it? I would appreciate hearing from you. Thank you for your time.

I RE: Frustrations of a County Resident �_�BY ND FOR EXECUTIYE I f.Y.l: Dear County Executive Locke: - I would like to explain to you the frustrations of a county resident who is getting answers to a ' problem we are experiencing. The problems I will discuss are partially caused by the county. '� My husba�d and I,along with neighbors Steve and Mary Keech, live aiong and at the bottom a. I, Class 3 Stream — it has no fish in it and is dry part of the year. The vounty(DDFS and Surface I Water Management)considers it"Sensitive"land. Last winter we had very bad erosion probiems. Above us on 148th Avenue SE a property owner clear cut his 5+acres. The stream runs through this property. We aze getting run-off from his property. Another property owner � (Blac�:mun) lives at the corner of State Route 900(Renton-Issaquah Road)and 148th Avenue SE. I Over the last year or so,he has been clearing his property(which he has every right to do). Now , we are getting additional run off Crom his property. The county's part of this problem comes from , the drunage ditch down 148th Avenue SE. Half way down the road,a culvert diverts the water ' under 148th Avenue SE and into our Class 3 stream. Now there is even more runoff water for us. In addition, there is runoff from a City of Renton Development called Summerwind. The City doesn't even acknowledge that this is something they aze to take care of. The water is coming down the hill and eating away at the property(in King Counry). Eventually it will affect us. And in the long-run,ttus siltlwater/debris runs into May Creek. � Last April,just to make sure everything was done properly,I called the Surface Water Management people to see what could be done. They came out and investigated. Last July Alan Meyers of SWM came out and again looked at our problem. Because we are only 2 home owners affected by this stream that have complained, nothing can be done. We were told that if a property owner's access to his home is threatened or a home is threatened by water/flooding, then something can be done. Earlier this week Mr. Blackmun was doing some additional grading/clearing of his property apparently with no permit,so after'talking to Mr. Meyers at SWM, I called in a violation. I got a call back from the Grading Depar[ment and they said that what he was doing was legal and no pennit was required. How can it be legal? We need a permit to fix our stream and he doesn't need a permit to fill it full of silt--it's the same water. Our property is being partially destroyed by the people upstream from us and we can't stop them. Mr. Blackmun wants to put a development on his properiy and we aze writing a letter to the Planning Department to express our concerns. It is going to cos[us$500- $2,000 to get a permit from the county and buy materials to fix our stream only to have it destroyed again next winter. I[will cost more for the pernut than it will to fix the job. We pay taxes to the Surface Water Management System, but we can't use the funds to . w j' � �-� �P v`� -" • a-� help us. We were also told that it would take 3 months for DDFS to review our application before we can even start—if we get approved. By then,it will be the middle of winter and the rainy season. We will probably have more problems this year. I know that everyone is just going by the ruleslregulations that are on the book, but this is frustrating. Will the county ever help us? I doubt it The reo�rds from SWM will confirm there is a problem. I was told by one of the county employees that the squeakiest wheel usually gets greased. I will continue to complain to SWM, the City of Renton and whomever until we get help. All I get from various officials aze comments like, "We don't have enough money to help everyone. If you had more of a problem,then we might be able to help you." "Maybe you should get politics involved." What does it take to have a real problem? I would like to invite you to our house to see what the problem is. The people in SWNi realize that there's a serious problem,but their hands are tied. Maybe if you come out and see some of the problems of us"little people"maybe then someone in government will help us and others like us instead of the"bigger fish". Maybe the money to be voted upon for the new stadium should go � instead to helping people with drainage problems. This is a lot bigger problem that keeping the . baseballlfootball teams in town. . Thank you in advance for listening to my frustrations. Sincerely, , C�-L�t��C.«/ � tJYI� � Claudia R.

I apologize for the delay in responding. The flooding of King County's major rivers - at the end of November drew staff inembers away from other duties. I would like to clarify Mr. Gettle's comments to you concerning the sediment leaving Mr. Backman's property. The Surface Water Management (SWM) Division's process for addressing this type of pmblem is through the Enforcement Program. Since the SWM Division does not have the resources to address all enforcements, they are prioritized to best utilize the resources available. As you can see on the enclosed Enforcement Prioritization System worksheet, the Enforcement Program does not address impacts to private property. (Private property impacts are addressed through the Neighborhood Drainage Assistance Program (NDAP), which I addressed in my previous letter.) The initial step in the Enforce- ment Program is to contact the owner of the property on which the violation ezists and ask them to correct the problem. The Backmans have been contacted by both SWM and Depart- ment of Development and Environmental Services staff and have been cooperative in imple- menting and maintaining Temporary Erosion and Sedimentation Controls. When Mr. Gettle referred to the problem on your property, he was referring to the cloudy 'i appearance of the water flowing through your property. The only idendfied problem ' associated with the suspended solids in the water flowing through your property is an aesthetic one. The particles in the water will not settle out of the water until the water comes to rest for a long period of time. The particles do not cause additional erosion, they do not pose a hazard to wildlife on your property, and they do not affect the capacity of the channel on your property. Although aesthetic problems are real problems, King County does not have the ' resources to address aesthetic problems on private property at this time. , SWM personnel have spoken with Paul Lumbert of the City of Renton Public Works Department. Mr. Lumbert indicated that he had not actually spoken with any King County �a � Claudia Donnelly - December 27, 1995 Page 2 employees regarding the County's policy of worldng in potential annexadon areas. Rather, he made a general comment that at some point King County would stop working (and spending money) in an area that had been, or would soon be, annezed. In general, this is an accurate statement; as I indicated in my last letter, however, the NDAP will continue to work on a project up until the date of annexation, at which point King County will wait for direction from the new jurisdiction on how to proceed with the project. Mr. Lumbert also confirmed that the drainage facilities in Summerwind Division 3 have recently been maintained and are functioning as they were designed. I regret any confusion created by a lack of communication between King County and the City of Renton. King County personnel are aware that Green Creek is a tributary of May Creek, and the SWM Division is currently preparing the May Creek Basin Plan, which will be submitted to the County Council and affected cities for approval in 1996. The Basin Plan is a comprehen- sive study of the May Creek basin and includes recommendations to improve water quality, improve wildlife habitat, and reduce flooding in the basin. The Basin Plan does not contain any recommendations for Green Creek and does not identify it as a significant source of sediment or suspended solids. Thank you again for your continued concern for Green Creek and the May Creek Basin in general. SWM has many volunteer programs for people who are concerned about the water resources of King County. If you would like more information about volunteer opportunities 'I at SWM, please contact Anne Bikl�, Cedar River/May Creek Basin Steward, at 296-1908. � S' , , I, I � � �, P Tanaka ! � Director � PT:bgo6o , Enclosure cc: Paul Lumbert, Office Engineer, City of Renton Public Works Jim Kramer, Manager, Surface Water Management Division ATTN: Dick Tfiiel, Manager, Engineering and Environmental Services Section Anne Bikl�, Cedar River Basin Steward, Watershed Support Unit .� �� . `�'�-� KING COUNTY SURFACE 1��ATER t�1ANAGEMEt�tT DIVISION , D�ZA.I�AG� ZI�IVESTIGA`Z'ION R�PORT � � Page t: INVESTIGATION REQUEST Type ��/ _ Received by: � - - Date.: , � - Cl OK'd by:� '-�t�� File ho, q'� _ �L,� ____ �---- ------------ -- -1�-��_- ___----------_--_------- -------� ReCe%v2d/fOR7: (Please print piainly fot scanninp), (Day) (Eve} NAM,c: /`-1�-•�G W�S�/i'?

There is no street drainage in front of her home so the water runs from the road frontage of the property to the west to the Westing property. It appears the water ponds in the frontyard and driveway against the house. Also contributing to the problem is the downspouts don't connect to a system so they flow into the same low area as the road runoff. It appears when the water gets high enough it runs towards the neighbors to the east. SR900 is maintained by the State. I will confirm that this road is not maintained by King County. If maintained by King County then information will be forwarded to King Co. Roads.

Seattle, WA _jtESPONO FOR EXECUTIVE REVIfWED iY � RE: King County Giving Permit Granting Authority to Renton f.Y.l. DearCountyExecutiveLocke: �: �N��C�� I would like to explain to you the frustrations of a county resident who is getting no answers to a � problem we are experiencing. You are our top County official who is running for governor. I ' would hope that you are also concerned about damage being done to our environment and the flaunting of rules that I have seen or heard abouG Just north of our house is the development of Stonegate. In January 1995, this property was annexed to the City of Renton. After talking to a Department of Fsheries person in November about some erosion problems in that development, I was told that the City of Renton has a poor e�vironmental record. This person also told me that every time he hears the City of Renton that it .� raises a red flag in his mind. This development has a habit of doing work on County property without having the proper permits. An example: At the north end of 148th Avenue SE, there is a bridge going across May Creek. The developers had private contractors put in a little walkway over the bridge and put a water pipe under the bridge without having the proper permits. How do I know this: I was told this information by someone in the Public Works DepartmenL This developer is now getting the necessary permits or intergovernmental agreement. On February 21, a contractor employee did some clearing work on a right-of-way on land located in this development. He then crossed over into property located in King County. This property is also located near a Class 3 Stream. There are no erosion barriers in place--just straw. (See enclosed pictures). If we get another heavy rainstorm, there is going to be alot of erosion coming down into that stream and going into May Creek. May Creek, by the way, has salmon in it. When • I asked this gentteman if he was going to put up the black erosion barriers, he said no. Then I told him I «•as going to call the City of Renton officials. He said,"Do what you have to do lady."- So, I called the City of Renton officials and they gave me no satisfaction. Then I called a land-use violation into DDES,I called SWM and filed a complaint,and I called another County oftice in � DDES concerned with environmental issues. I also talked to a lady in the land use office and she stated that this developmenticontractor had no permits to do any type of clearing in King County. Since I didn't get any response from the County, I also called the State Department of Ecology. On that Friday, I got a call from an inspector and she said that the County would fine the developer for not having pennits. Then I got a call the next day from this same lady and she said that Renton had all the permits. I did not understand what she meant. In addition, I received another call from a different DDFS office who said that I shouldn't call the Department of Ecology. Well,if the County dcesn't care about this land then maybe I should call the state. This afternoon, I spoke to someone in a DDFS car and he told me that King County had given the City of Renton the authoriry to grant whatever permits it wants for work on County land. How can that be? It we did some clearing by this Class 3 stream, we would have to get permits from the `�..- � �� County. Plus we would have to put some erosion barriers. How are we going to protect this stream from damage?The City of Renton surely isn't going to do so. Last November I called the . City of Renton about environmental damage(that I had pictures on that was occumng in this development. This Renton official only got concerned when a Department of Fishenes person came out to do an inspection. Who do we call to complain to when the contractor screws up on County land? No one in the Counry seems to care about this land except us. Do you also know that the Ciry of Renton wants to vacate a portion of a County Road -- SE 100th �'� Street. The City of Renton is wing to do this without all the necessary permits. What gives the � City of Renton Ehe right to do this without talking to the County? I have been told that the City;� now talking to the Department of Public Worlcs about vacating this road. Again, this is happening after the fact Sincerely, �� '� Claudia R.

On 148th Avenue SE, north af State Route 900, are two culverts diverting water from the ditch along side 148th, under the road through people's yards and into Greenes Stream and then onto May Creek. My neighbors and I get tl'ie wafer from the first culvert—500 feet north of the State Route 900. We have tried for years to get help from SWM. But since we are only 3 houses that flood out, have erosion damage, etc.,we don't counUrate. I wrote you previously about this problem. I eventually fold SWM to forget us as we were 9 out of 9 probjects. This personmtold the Renton City officials and the developer that if the water got to be too bad coming from 148th at SE 102nd ST. and it started flooding the nice new homes that are to be built in Stonegate, that the County might have to fix that problem and divert the wate�to May Creek alongside the road. DDES told another lady that gets the same water and is wrecking her property NO when she asked if she could put a pipe in to channel the water �^a �rotect her property.

I, As I mentioned to Mr. Irons in my response to him, this isn't the only '�i incident that KC seemed to look the other way. Last summer, when the stream � bed (Greenes Stream)was dry, a neighbor down my road, dumped 4-5 dump trucks I loaded with top soil into his back yard. His back yard borders on Greenes Stream. He put no erosion barriers up or planted grass- nothing . I still think there is just dirt back there. Anyway, f called DDES and filed a i complaint. I was told that because the stream was dry that DDES didn't care about all the dirt. I called Governor Locke's Puget Sound person and he told � me to call someone in Seattle. Then I sent a note to someone in the Dept. of Natural Resources. I got a reply back, I'm not say from whom; saying that because KC Dept. of Natural Resources had over 700 miles of streams to take I care of(and ours was dry), he didn't care about possible erosion when winter came. I guess we just don't rate. And then this. Like I said, as soon as it is daylighE, I will check the water quality to see what I can see.

Thank you for expressing your continued concems regarding the water quality of Greenes Stream and its impact on May Creek. I understand how much you care about the health of May I Creek as a long rime resident of the May Creek basin. I am writing to let you Imow the resuits of our I investigarion and what we plan to do next. I, Staff from the King County Departments of Transportation and Natural Resources completed a site visit oo �' January 30,2001 to assess potential sources of contaminants that are entering Greenes stream and May Creek based on the water samples you collected. Water Quality staff in the Department of Natural Resources(DNR)reviewed the analysis performed by AmTech on your water samples of January 4 and 5,2001. Based on the information provided to you by AmTech,we recognize that oil is entering Greenes sh-eam which is a concern. As only one sample was analyzed for oil,it is difficult to determine if the oil was from a one-time event such as an intentional '� dumping of oil,or from an ongoing problem within the watershed. T'he rainfall event on January 4,2001 , was the fust heavy rain in over 2 weeks. This"fust flush"event would have elevated pollutant loading into ' all drainages. However,we are still concemed that oil and grease is being introduced to the stream system, which discharges to May Creek. The regulation that currently exists to control the release of contaminants from residential properties is the King County Water Quality Code. If pollutant discharges are observed on residential properties,the water quality code dces allow for recommendations and technical assistance to property owners to reduce and eliminate pollution generating activities,such as vehicle repair and increased erosion conh�ol. Our first response to these problems is technical assistance and education. However,violations of the water quality code can be issued to residential property owners if best management practices are not implemented or an intentional act of dumping pollutants has occurred that is well documented. Although the samples you had analyzed do not provide us with data that can be used to enforce our water quality code at one specific site,through additional investigarion and sampling,we may be able to idenrify sources that would allow us to pursue our regulatory authority of the water quality code. Our sampling and monitoring will include all areas where stormwater enters Greenes stream throagh pipes or ditches. These additional invesrigations and sampling procedures requue the approval from private property owners for , access to theu properties. By gaining access to private properties we can assess activities that may be ' conh-ibuting to water quality degradarion within the May Creek watershed. We will continue to work within our regulatory guidelines and authority to assist property owners in implementing source controls to reduce pollution generating activities that affect Greenes Sh�eam and May Creek. DNR staff will keep you apprised of the work being completed in the Greens s�eam basin and the results of this work. If you have any further questions please feel free to contact Susan Clarke,Engineer in the Water and Land Resources Division of the Department of Natural Resources,at(206)296-8311. z � . � � O_ ... a � , .�� ,. - r� - ,.:. _ ,�� .-w...z<.' . ;:�.a f r � DRAIN"AGE INVESTIGATION REPUf2`I' �"��r �. .; '� ,,� y x :�'�.� - �� . - • , ,� , ' _ = � , ��, �1yESTIGATION REQUEST , ., -_ "j YP� � � �L�T��.�i/J//! . � - .?:� ItOBLEM: w,- �:� � �- �_ x� �� .x �,�' ,'�,-s � ?.,,• y *';.,, ...., . . . . . . .� � '.. -:_,._` ' _ . .;.-. ?,aF';t'r�'�r _ ^�C 32t.�-��. rRECEIVED BY: �U� "e-- Date: �� OK�c� �.��_ �-: .5 � FiF: Received from: . _ - -. k��.�,.�.�� - �.~ 1 y _ � __ (Day} �l��-:" NAME: �Yti .

I also nppreciated having the chance to talk with you on the telephone. King County Executive Ron Sims has asked me to respond to you on his behalf as well. I hope this single email will cover nll of your concerns! I understand your frustration regarding the many issues you have rc►ised and the vorious depQrtments that are involved. I hope your conversntion with Sue Clarke of my stnff hns clarified some of the issues that are within the responsibilites of the Water and Land Resources Division (WLRD)and the Department of Natural Resources (DNR). In regards to your question about how King County will protect your property from flooding and erosion/sedimentation problems; King County regulations, specifically the King County Surfnce Water Design Manual uddresses the potentinl downstream impncts from new developments nnd construction. The requirements in the Manual use the best avoilable science und technology to avoid or minimize adverse impacts to downstrenm properties. As pointed out in your emnil transmittal of April 6th, the current Design Manual requires wetpond designs to meet the goal of 80 percent Totn! Suspended Solids (T55) removal through the construction of water quality facilities. Sometimes, even higher removals are renlized. Additionally, the May Creek Action Pfan recommends Level 2 stream protection standards to over detain flows to reduce flow and sediments ta May Creek. The upstream development (Stoneridge) currently under review by the Department of Development nnd Environmentnl Services (DDES) is using Level 3 protection in the detention nnd water quulity facility design. This protection standard is a more restrictive standard than currently required by the Design Mnnual or recommended in the May Creek Basin Plan. I Other regulotions include the King County wnter qunlity code, which uses technical assistnnce ns its first approach to water qunlity problems on existing developed properties. The sediment/oil you have seen in Greenes Stream comes from many non point sources such as individual residential drivewnys and gravel roads,which King County can't (egully enforce because the Water QuQlity code I� exempts these types of normnl residential activities in regards to these pollutants. However, if a I determination is made thnt polfutant discharges are due to intentional dumping or illicit connections, I� violations can be issued. You might want to work with the Moy Valley Environmental Council (MVEC) as well ns the Basin Steward to provide outreach to neighbors in encouraging individual property owners to voluntarily reduce runoff from their sites. KCWLRD has printed information that cnn be �� made available to MVEC to use in an outreach cnmpaign. Additionnlly some staff time could be made ; available to provide informational workshops or mailings to residents within the bnsin. � i � .;:,. . �:- : - , �- ��..::,.x � 3�:�, _ . our concerns that Greenes Strenrn does not seem to be getting the snme leve) of attention as other urban streams in King County. Other streams that you have referred to currently hnve adopted Basin Plans. Through the planning process, projects are identified and prioritized for potential construction when funds become available. Once the May Creek Plan is adopted, this process can be applied to May Creek. As the May Creek Plan recognizes, the creek does huve viable habitat in its lower rwches and King County nnd other jurisdictions ngree that this habitat needs to be protected. However,ngreements with these other jurisdictions such ns the cities of Newcnstle nnd Renton along with privute property owners must occur before projects, like those in the �esMoines Creek wntershed can be pursued. This cooperative effort in the DesMoines Creek watershed is an excellent example of what can be accomplished when private and public interests work together. Through the May Creek Bnsin pinn we hope thnt the snme type of cooperntive agreements cnn be reached. Your comment regarding King County staff calling citizens names is of n great concern to me. King County WLRD staff nre expected to treat all citizens with respect and concern even "off the clock" I am not aware of any staff making derogatory remarks or ►wme calling of citizens. If you hove knowledge of such incidents,I encournge you to speak with me so that I can address any specific problems. Plense do not hesitate to contact me at (206)296-6585. I believe your comments regarding the DDES permit file for the mobile home at 10726 - 148th SE was nddressed during your conversation with Sue Clnrke on Thursday April 5th. To reiterate whnt she shared with you,she recognizes that there is a hydraulic connection between Greenes Strenm and May Creek, however, no distinct channelized connection of surface water is evident. Greenes Stream enters wetland #5, which is noted in the May Creek Current and Future Conditions Report as among the largest known freshwater wetland in King County. Water from 6reenes stream flows in a braided fnshion through this wetlnnd, which allows for naturnl wnter qunlity treatment prior to discharge to May Creek. During Sue's site visit of April 5th this wetland nrea was found to hnve n large nmount of nnimal droppings (horse manure) Sue will research the ownership of this property, work with the owner on removal of the pollutants and refer the problem to the Livestock Program Analyst Laurie Clinton. The May Creek Conditions report acknowledges thnt Greenes Stream is n flnshier creek and responds to precipitation much more quickly than other drninages within the Basin which is why you are probably seeing flow increnses occurring on your property quite quickly nfter n rainstorm. However, the impacts to May Creek are not ns significant regnrding peak flow as other basin wide strenms due to the attenuation within Wetland #5. Overull the May Creek Basin Plnn contnins I recommendations to correct or reduce flooding and water quality problems in the basin and to help prevent probfems from worsening in the future. ' Thank you again for writing nnd expressing your concerns. We look forward to working with you in the protection of water quality nnd hnbitat values in May Valley. If I can be of further assistance at this point, please do not hesitate to contact me again.

Senator Murray forwarded your letter to me requesting that I look into your concerns and respond to you directly. Most of the questions raised in your letter have been addressed in previous correspondence dated February 20, 2001 and April 12, 2001, from Nancy Hansen, Manager of the King County Water and Land Resources(WLR) Division of the Department of Natural Resources, and me. Copies of these letters are enclosed. I have coordinated this response with Ms. Hansen, and this letter constitutes a response from her on the specific questions you have previously addressed to her. I want to first reassure you that King County is not ignoring the Endangered Species Act (ESA), and shares your goal of protecting salmon in May Greek. King County is considered a leader in the development and implementation of new programs and regulatory updates to address the listing of the Chinook salmon and Bull Trout in response to the ESA listings. These approaches will be applicable Countywide, including May Creek. In your letter yoU asked why you, as a downstream property owner, must accept increased runoff and sedimentation from upstream development. King County's drainage code is designed to minimize impacts from new developments and comply with Washington State case law. Washington State case law states, in general, that a property owner is not liable for incremental increases in storm water quantity or velocity in a downstream natural conveyance system provided that the increases are not done in a negligent manner and water is not diverted from one drainage basin to another. Core Requirement #1 of the Surface Water Design Manual prevents diversions of water from one basin to another. Core Requirement #3 requires flow control facilities to reduce peak flows leaving a development to match peak flows occumng prior to development. Core Requirement #8 requires water quality facilities to reduce the impact of development on the quality, including sedimentation, of our local waters. While following the Manual's requirements will reduce the effects of new developments, it cannot eliminate all the effects of new development.

The 80 percent removal of TSS goal for new retention/detention (r/d) facilities is a matter of economics and technology. Larger r/d facilities would remove more suspended solids, but larger facilities are also more expensive to build. The cost to build larger facilities is passed along to the consumer in the form of higher housing prices. From a technological standpoint, there is also a point where building a larger facility will not remove any more TSS because the particles become so small they will not settle out without chemical treatment. The goal of 80 percent TSS ' removal was chosen as an appropriate standard because it is believed to provide the best cost/benefit ratio for removal of TSS and is the standard that is required by the Washington State Department of Ecology for stormwater yuality. With regard to the questions you feel Ms. Hansen has not responded to, here are the answers that she has provided me with: . 1) What is King County's real plan for the May Creek Basin Urban area? There is no secret associated with the May Creek Basin Plan. The Basin Plan contains comprehensive zoning and regulation recommendations to address issues related to future growth, as well as basinwide and site specific recommendations to address existing problems. May Creek Wetland #5 is a Class 1 wetland, which King County Code does not allow to be developed into a regional detention facility. However, one of the benefits of wetlands is that they store large amounts of water. The basin plan ', recommendations seek to protect the natural benefits associated with the May Creek � system while addressing specific flooding problems through capital projects and technical assistance. The "real" plan for May Creek Basin is the Basin Plan, which was very recently approved and adopted by the King County Council, the City of Renton, and the City of Newcastle. 2) What May Creek tributaries does King County consider important? King County does not typically undertake a thorough ranking of the relative importance of all tributaries within a basin planning effort. However, areas of particularly high-quality habitat which make significant contributions to the resource base of the basin, are identified as "Significant Resource Areas" and are categorized as either"Regionally"significant, or"Locally"significant. Stream reaches and wetland areas considered to be Significant Resource Areas in the May Creek basin are identified in Appendix E of the adopted basin plan. This is not to say, however, that Greenes stream is an unimportant resource just because it does not provide the same habitat values as the significant resource areas. � - Page 5 _�_._..� _ _ I also understand that you have been in contact with the King County Ombudsman with your concerns. 1 think this is a very appropriate step if you feel that you are not getting appropriate treatment from County staff. I have asked Ms. Hansen to work closely with the Ombudsman's office to ensure that the Division is being appropriately responsive to your concems. If you have further questions or concerns, please continue to contact Nancy Hansen, Water and Land Resources Division Manager in the Department of Natural Resources, at (206)296-6585. As is King County procedure, she will assign follow-up to the staff with the appropriate programmatic and technical expertise.

This e-mail speaks to a plugged culvert that was investigated by SWM. While she mentions that SWM advised her that there was a code violation, no such report has come into DDES from SWM. To the contrary, our most recent conversations w/Brian Sleight of SWM indicated that he saw no code violations out there. Ms Donnelly made a FOIA request of DDES on 12/18/01 for specific information about which developments in the area required a level 3 detention pond. We provided her w/that information (see red highlighted response from Ms Donnelly, below) In her 1/9/02 e-mail, she stated her recent request for information was not made to DDES, however it is not clear to which department she made the request. 1 am cc'ing folks in SWM to see if they are aware of any recent request for information from Ms Donnelly. If so, please let Ron know and respond to Ms Donnelly on his behalf. If not, also advise Ron and I guess we should ask her to specify which department she made the request of. DDES and DNR have been extremely responsive to Ms Donnelly over the years...she simply does not like the answers we are providing her and I doubt she ever will. That being said,we still need to respond to any and all FOIA requests. gk -----Original Message----- From: Sims, Ron Sent: Wednesday, January 09, 2002 10:26 AM To: Kipp, Greg Cc: Whalen, Caroline; Brandon, Rod Subject: FW: RCW 42.17 and FOIA violations Greg-please follow-up, thanks. - ron -----Original Message----- From: Mike and Claudia Donnelly[mailto:thedonnellys@oo.net] Sent:Wednesday,January 09, 2002 10:32 AM To: ron.sims@metrokc.gov Cc: david.irons@metrokc.gov Subject: RCW 42.17 and FOIA violations Dear County Executive Sims: 2 P . ,. - I have told you over and over again that KC doesn respon o _ :.._ us who live in this part of the May Creek Basin area. Here is another example. A neighbor down our road has plugged a culvert draining water from 148th Avenue SE through her property to Greenes Stream. She plugged the culvert up because she didn't want the water flowing through her property. In November,this plugged culvert sent water down a small, shallow ditch alongside 147th Avenue SE. That excess water caused sheet flooding over the road. It also caused water to go through another neighbor's garage. This problem was called in Roads and SWM. It was investigated and supposedly something will be done--once Roads gets the permits its has applied for. SWM investigated and found out that this neighbor(plugging the culvert) is violating County Code. They were going to send a letter to this person advising them of this violation. Well, I talked to the neighbor who got the water in her garage and asked if she had gotten a copy of the letter that was supposed to be sent. She said that she might get a copy--she wasn't sure. On December 28, I typed several letters to KC Departments (not DDES (emphasis added by kipp)--even though I don't like DDES and they don't answer my questions) requesting documents under the Pubtic Disclosure Law (RCW 42.17)and FOIA. I mailed these letters on December 29. I also sent a letter to a Washington State agency-- they responded promptly. heard from one person--they said that they'd return my 30 cents and the letter to the person plugging up the culvert had just gotten back from the Word Processing Dept(this is last week). I still haven't gotten a copy of that letter. Has it been sent????? I sent this person a note today asking if the letter has been sent and if not, when will it be sent? So far, no response. The other KC agency hasn't responded at all. The letters should have gotten to the people on December 31. If I have to go to an attorney to get a response from this KC agency, I will send my attorney bill to you. You might want to send out a note to all County employees that the public has a right under FOIA and RCW 42.17 to see and have copies of County documents. Again, maybe you can answer the question as to why KC doesn't want to make my neighbors comply with County and State laws? There is Mr. Wolf, who change the course of Greenes Stream and he didn't get fined; there are the 2 Code violations on the Luck property that have been in limbo for many years now; there is the Nagel culvert problem? But then another neighbor put a little dirt in her back yard next to Greenes Stream and she had to pay a fine? Why are people treated differently? Thank you for your time. iia Donnelly -----Original Message----- From: Mike and Claudia Donnelly[mailto:thedonnellys@oo.net] Sent: Wednesday, January 09, 2002 1:59 PM To: paula.adams@metrokc.gov; robert_ware@metrokc.gov 3 Dear Ms.Adams: I just received your letter with the list of developments that were required to have a Level 3 detention pond along with a Level 3 Flow Control. THANK Y�U VERY, VERY MUCH FOR THE INFORMATION! It was nice and timely. I don't need to see the files--so they can be returned to wherever they are kept. For this part of my research, I just needed the development name and file number. For the next part, I need to go somewhere else. But thank you, any way, in having Mr. Ware keep them for me. Mr. Ware is a wonderful, friendly person — I like him very much. He is a good asset to DDES. You are, also, a pleasure to work with. THANK YOU AGAIN.

The letter has not gone out yet (i just got it back from word processing today) but I will get you a copy when it is sent out. I'll also send your 30 cents back with it. Technically there should be a charge for the copy but our office doesn't accept cash (only checks) and even if they did, the cost in time for me to get a receipt and such for one copy would be way more than the cost of the copy. Len Juhnke and I met with D.O.T. staff last week to look at the quick fix. I called you before we left downtown but you were not there. Len will be handling the project in my office. The project will involve paving that area that the cars drive over, extending the berm, and digging a shallow ditch a short way to the north. The project will not dig the ditch past the area where the retaining wall is failing. The idea is to piggyback our work with the roadside ditch cleaning because the crew will already be out there. Therefore, the timing is dependent on the roadside ditch project. At the time of our meeting, the environmental paperwork had been submitted and they were waiting for approval. E�en with the intent of the piggyback project, if the weather is not appropriate for paving when they clean the ditch, they won't do the quick fix. The quick fix will still get done, it will just get done at a different time when weather permits. If our current run of dry weather holds, it shouldn't be a problem but if we start getting steady rains day after day, the weather and crew availability could push the project off to this spring.

Executive Suns has asked me to respond to your concerns. Your email also expresses concems about King County enforcement of drainage problems in your area. I understand your public disclosure requests were made to the Department of Transportation(DOT)and the Department of Natural Resources,which is now called the Department of Natural Resources and Parks(DNRP). DNRP staff sent you an email on January 2,2002,the day your request arrived. T'he letter you requested was only in draft form at the time of your request and,as such,was not yet disclosable by law. Rather than ask you to resubmit your request after the letter had been signed and sent,DNRP staff said they would send you a copy as soon as the letter was sent,which they did on January 10,2002. DOT staff sent you a letter on January 9,2002,five working days after your request amved. Your request involved a large file and it was not clear what specific documents you were requesting. DOT staff thought the best response would be to make the file available for your review so you could decide which documents you wanted to copy. From my understanding of RCW 42.17,the response from both the DNRP and the DOT exceeded the requirements of RCW 42.17. In regards to your enforcement concems,King County's enforcement authority applies to all of unincorporated King County. In the practical application of the codes granting such authority,there is no distinction between people living in rural areas or in urban areas. King County,however,has a high burden of proof when it comes to taking enforcement action against a code violator. As unfortunate as it may seem,there are times when it appears a code violarion has occurred but King County cannot take action because we cannot prove that a code violation occurred or do not lrnow who performed the act. In the case of Mr.Wolf,both the Departrnent of Development and Envuonmental Services(DDES)and DNRP staffhave invesrigated the complaint and found no evidence that a code violation has occurred. Mr. Wolf stated the stream relocated when several trees fell during an ice storm in the winter of 1996/97. T'his is a natural and common occurrence and,with the number of fallen trees on Mr. Wolfs property,there is nothing to suggest it did not occur. With no physical evidence to support an enforcement case,the word of one neighbor against another is unfortunately not enough to overcome our burden of proof. In the case of the Luck property,enforcement action was initiated against the property owner for installing a culvert in a sensitive area without a permit. The property owner has applied for a grading permit for the culvert installation to resolve the enforcement. There are other code compliance issues on this property but they cannot be addressed until the grading permit is issued so the rest of the property can be accessed. • In the Nagel case,Water and Land Resources Division(WLRD)staff has an open enforcement case for this violation and the first step in the enforcement process has been taken. WLRD allows the property owner 30 days to voluntarily resolve the problem before a formal enforcement process with possible civil penalties is initiated. If Ms.Nagel does not resolve the violation within 30 days,she will be sent a Citation in accordance with King County Code 23.20. My staff who are most familiar with your neighborhood do not recall a fine levied against your neighbors. However, if your neighbors think the fine was inappropriately levied,they should contact the department that they were working with. The resolution of any code violation is greatly affected by the conduct of the violator. While the enforcement and possible enforcement cases you have mentioned each have a different resolution and may not be the resolution you want,there does not seem �be any inequity in the application of King County's enforcement authority. While 1 am sure the issues you have raised are of great concern to you,in the case of your public disclosure request,if you had waited an appropriate length of time(i.e. a couple days after the response deadline to allow delivery by ihe post office)you would have seen that County staff did comply with the requirements of RCW 42.17. Similarly,in the case of the enforcements you mentioned,County 1 staff is taking action as aut orize y ing oun co e on e i issue they have looked at and determined that acrion cannot be taken(Wol�. I admire the amount of effort and encrgy you put into your community but I ask you to accept the determinations made by County staff and limit future contacts to new issues. Thank you again for the opportunity to address your concerns. I hope we can move forward to new issues and opportunities.

This e-mail speaks to a plugged culvert that was investigated by SWM. While she mentions that SWM advised her that there was a code violation, no such report has come into DDES from SWM. To the contrary, our most recent conversations w/Brian Sleight of SWM indicated that he saw no code violations out there. Ms Donnelly made a FOIA request of DDES on 12/18/01 for specific information about which developments in the area required a level 3 detention pond. We provided her wl that information (see red highlighted response from Ms Donnelly, below) In her 1/9/02 e-mail, she stated her recent request for information was not made to DDES, however it is not clear to which department she made the request. I am cc'ing folks in SWM to see if they are aware of any recent request for information from Ms Donnelly. If so, please let Ron know and respond to Ms Donnelly on his behalf. If not, also advise Ron and I guess we should ask her to specify which department she made the request of. DDES and DNR have been extremely responsive to Ms Donnelly over the years...she simply does not like the answers we are providing her and I doubt she ever will. That being said, we still need to respond to any and all FOIA requests. gk -----Original Message----- From: Sims, Ron Sent: Wednesday, January 09, 2002 10:26 AM To: Kipp, Greg Cc: Whalen, Caroline; Brandon, Rod Subject: FW: RCW 42.17 and FOIA violations Greg -please follow-up, thanks. - ron ---Original Message----- From: Mike and Claudia Donnelly[mailto:thedonnellys@oo.net] Sent: Wednesday, January 09, 2002 10:32 AM To: ron.sims@metrokc.gov 1 � _".__ `.."_.._�_.�. ..._J / ar C De ounty Executive Sims: I have told you over and over again that KC doesn't respond to those of us who live in this part of the May Creek Basin area. Here is another example. A neighbor down our road has plugged a culvert draining water from 148th Avenue SE through her property to Greenes Stream. She plugged the culvert up because she didn't want the water flowing through her property. In November, this plugged culvert sent water down a small, shallow ditch alongside 147th Avenue SE. That excess water caused sheet flooding over the road. It also caused water to go through another neighbor's garage. This problem was called in Roads and SWM. It was investigated and supposedly something will be done--once Roads gets the permits its has applied for. SWM investigated and found out that this neighbor(plugging the culvert) is violating County Code. They were going to send a letter to this person advising them of this violation. Well, I talked to the neighbor who got the water in her garage and asked if she had gotten a copy of the letter that was supposed to be sent. She said that she might get a copy--she wasn't sure. On December 28, I typed several letters to KC Departments (not DDES (emphasis added by kipp)--even though I don't like DDES and they don't answer my questions) requesting documents under the Public Disclosure Law(RCW 42.17)and FOIA. I mailed these letters on December 29. I also sent a letter to a Washington State agency—they responded promptly. I heard from one person --they said that they'd return my 30 cents and the letter to the person plugging up the culvert had just gotten back from the Word Processing Dept(this is last week). I still haven't gotten a copy of that letter. Has it been sent????? I sent this person a note today asking if the letter has been sent and if not, when will it be sent? So far, no response. The other KC agency hasn't responded at all. The letters should have gotten to the people on December 31. If I have to go to an attorney to get a response from this KC agency, I will send my attorney bill to you. You might want to send out a note to all County employees that the public has a right under FOIA and RCW 42.17 to see and have copies of County documents. Again, maybe you can answer the question as to why KC doesn't want to make my neighbors comply with County and State laws? There is Mr. Wolf, who change the course of Greenes Stream and he didn't get fined; there are the 2 Code violations on the Luck property that have been in I limbo for many years now; there is the Nagel culvert problem? But then another neighbor put a little dirt in her back yard next to Greenes Stream and she had to pay a fine? Why are people treated differently? I Thank you for your time.

King County Executive Ron Sims has asked me to respond on his behalf. I understand that Brian Sleight, Stormwater Services (SWS) Section Senior Engineer from my staff, visited your neighbor's property on March 7, 2003. At the time, no sediment was leaving the site even though it was raining lightly. There were no indications that sediment had previously left the site. The owner was not home so Mr. Sleight left a note on their door requesting that they contact him. Your neighbor called Mr. Sleight that day and was advised of his responsibility to minimize sediment transport from his property. Your neighbor said his intention was to stabilize the area this past �veekend 3121/2003 - � and asked Mr. Sleight to visit the site on Monday, March I 0 to determine if the site was properly stabilized. A Monday site visit showed that straw had been placed on much of the site. Mr. Sleight asked your neighbor to extend the straw to the end of the existing railroad tie wall, which the neighbor said he would do. ' It is im ortant to note that installation of erosion control ment ractices BMPs will n I p best manage p ( ) ot completely eliminate sediment transport from your neighbor's property. Erosion control BMPs are intended to minimize the impact of exposing bare soil by preventing soil from getting suspended in water or removing suspended soil from water. Once sediment is suspended in water, short of using , chemicals, erosion control BMPs will not remove very fine sediment from the water. Although these I BMPs are not perfect, they are consistent with Washington State's requirements to use all known, '' available, and reasonable methods of prevention, control, and treatment of stormwater. These BMPs �I also meet the Clean Water Act's requirement of stormwater controls to reduce the discharge of pollutants , to the maximum extent practicable. I Thank you for taking an interest in the environment.

Since the City of Renton has indicated that Level 3 Flow Control and Basic Water Quality are the required means of detaining runoff and treating the runoff, which is more than the Flow Control Applications Map in the 1998 King County Surface Water Design Manual requires, this project assumes those are adequate for this site. By utilizing Level 3 Flow Control this project should not aggravate or create a problem as specified in the problem-specific mitigation requirements set forth in Section 1.2.2.1 of the 1998 King County Surface Water Design Manual. A Level 2 or a Level 3 off-site analysis should not be required for this project site. In addition, the project site is not flat no: is ihe downstream drainage course flat and the site does not contribute more than 15 percent of the total peak flow drainage downstream from the site. 11189.003.doc[]PJ/dm] 4.0 FLOW CONTROL AND WATER QUALITY FACILITY ANALYSIS AND DE5IGN 4.0 FLOW CONTROL AND WATER QUALITY FACILITY ANALYSIS AND DESIGN A. E�sting Site Hydrology The pre-developed and post-developed basin areas match each other in size and the upstream basin contributing runoff to the project site will be bypassed around the project site or through the project site and not impact the detention system proposed for this development. Please see the following table for a list of assumptions and parameters used in sizing the pre-developed conditions hydrographs for this project. EXISTING CONDITIONS TABLE On-Site• Existing impervious = 0.52 Acre Effective impervious area of gravel=0.3 Ac. x 0.5 =0.15 Acre Existing impervious total = 0.52+0.15 =0.6"7 Acre Till forest = 9.51 Acres Till grass = 3.1 Acres+0.15 Acre(1/2 gravel area)=325 Acres Total On-site = 0.67+9.51 +3.25 = 13.43 Acres Additional Tract to Northwest: Till forest = 2.34 Acres Imnrovements to 148th Avenue S.E.: ' Till grass = 0.17 Acres Imnrovements to SR-900/148th Avenue S.E.: I' Till grass = 0.25 Acres I b Total existing azea = 16.19 Acres of which there is: till forest = 11.85 Acres till grass = 3.67 Acres impervious = 0.67 Acres 16.19 Acres B. Developed Site Hydrology The existing site as well as the developed site occurs in Alderwood type soils that are a till type soil. The proposal for this development is to construct a Level 3 Flow Control detention pond above a basic water quality wet pond in the north central portion of the site. Upstream runoff from the south, east, and west will be routed around the detention and water quality facilities located on-site and bypass those facilities. Please see the 11189.00I.doc[JPJ/dm/tep] following table for the assumptions and parameters used in determining basin areas contributing runoff to the weddetention pond. DEVELOPED CONDITIONS TABLE On-Site• ' Impervious: 491ots x 4,000 SF/lot=4.5 Acres Future 81ots in southwest corner= 8 x 4,000=0.73 Acre Streets and sidewalks=2.26+0.45 =2.71 Acres Total Impervious On-site = 7.94 Acres Till grass = 5.49 Acres Additional Tract to Northwest: Impervious = 1.27 Acres Till grass = 1.07 Acres Improvements to 148th Avenue S.E.: Impervious = 0.17 Acres Imnrovements to SR-900/148th Avenue S.E.: Impervious = 0.25 Acres TOTAL DEVELOPED AREA: Impervious = 7.94 + 1.27 +0.17 +0.25 =9.63 Acres Till grass = 6.56 Acres TOTAL = 16.19 Acres C. Performance Standards As mentioned previously the flow control performance standard utilized for this development is Level 3 Flow Control due to downstream problems that are well , documented at King County. The water quality performance standard is to provide Basic Water Quality as dictated by the City of Renton and King County, which this project proposes to do in the form of a wet pond. The conveyance system capacity standard is to convey the 25-year storm based on the SCS-based Santa Barbaza Urban Hydrograph methodology of computing peak flow rates contributing to each catch basin since the project site is over 10 acres in size. 1 ll89.001.dce[JPJ/dm/tep] D.

This will act as a sediment pond, trapping sediments on-site and preventing erosion from occurring on-site and sedimentation downstream. In addition a rock construction entrance and perimeter protection in the form of a silt fence with temporary V-ditches and rock check dams will all be instituted on-site to minimize erosion from occurring. Also, streets will be swept should any sediment be tracked off-site from truck hauling activities and the site shall be sprinkled with water during the summer months should dust contro} be a problem on the site. Cover measures will be instituted for any areas left unworked over the time allotted by King County and the City of Renton. 1 I]89.00l.doc[JPJ/dmltep) Appended on: 11:34:11 Thursday, March 18, 2004 11189site east graded Event Summary � Event �'�Peak Q (cfs)IPeak T (hrs)�Hyd Vol (acft);Area (ac) �Method �'Raintype� �6 month ' 0.4798 �8.00 � 0.1808 I 3.2500 SBtTH ;TYPEIA I r-- j 2 year � 1.0549 8.00 0.3629 " 3.2500 � SBU:TYPEIA � � � � � , --�--------r------ ` 10 year :-_1.6545 � 8.00 I 0.5534 j 3.2500 !

There is 33.6 acres of upstream area contributing runoff to the south property line of the site. Please refer to the upstream basin map within the appendix of this report for an explanation of the upstream basin. In addition, a hydrograph has been prepared for this upstream basin and is also incorparated herewith in the appendix in the form of a basin summary from the storm shed model for your reference, which indicated a 100-year peak runoff rate of 7.27 cfs, which is being conveyed through mostly 24-inch pipe through the center of the site bypassing the on-site water quality and detention facilities proposed for the Stoneridge plat. To be conservative, the entire upstream basin was routed through the 24-inch pipe, which is laid at 0.5 percent of slope. Please refer to plan and profile drawings also included in the appendix of this report for an explanation of how water is conveyed through the site. The worst-case condition was to route the 100-year Q from the entire upstream basin through the 24-inch pipe, laid at a 0.5 percent slope, and the Flow Master computation form indicated the pipe would flow approximately half full during the 100 year storm event. The remainder of the 24-inch pipe downstream of the slope laid at 0.5 percent is at a much steeper slope and will have no problem conveying the runoff from this entire upstream basin. We think this a very conservative design and should pose no problem for bypassing flows through the site. 11189.013.doc [JPJ/tep] APPENDIX A UPSTREAM BASIN MAP �� i � � !_. i ,, J'/--- / V�' , ��/./O�/ / ; . � '',;�, .
