Study Area Definition and Maps The Jessie Glen Preliminary Plat is a proposal to subdivide a 7.7 acre parcel into 48 single-family residences. The project is located in unincorporated King County, on the east hill of Kent The project is more specifically located between 116th Avenue SE and 120th Avenue SE, just north of SE 192nd Stree~ and includes King County Tax Parcel Numbers 6198400-0080, 619840-0100, 619840-0120, 619840-0140, and 619840- 0320. Please see Appendix A for vicinity map. This property is partially undeveloped and also contains a few existing residential homes. This property is generally surrounded by lower density single-family residential development; however, there are a few similar, higher density projects in various stages of development in the immediate vicinity. The runoff from the site currently sheet flows from the west to the east toward 120th Avenue S.E. Approximately 2.9 acres of area drains to the site from the west The project is located within the Soos Creek drainage basin. The drainage study area is approximately one quarter mile long path encompassing the site's downstream corridor. See the exhibit in rear pocket of this report for a topographic map of the site and a map of the basin study area 1 Task 2. Resource Review The following resources have been reviewed for the downstream analysis: Adopted Basin Plans • The site is located within the Soos Creek Basin. Floodplain/floodway (FEMA) Maps • There is no mapped floodplain in this area per the available FEMA Maps. The site is located in Zone X per the Flood Insurance Rate Map (FlRM) map number 53033C0991 F. A copy of the FlRM map is included in Appendix B of this report Sensitive Areas Folio • Wetlands -None mapped. • Streams and 100-Year Floodplains -None mapped • Erosion Hazard Areas -None mapped. • Landslide Hazard Areas -None mapped • Seismic Hazard Areas -None mapped • Coal Mine Hazard Areas -None mapped. DNRP Drainage Complaints • Drainage complaints are located in Appendix E of this report U. S. Department of Agriculture, King County Soils SUNey • The soils are predominantly of the Alderwood series (AgB). A copy of the King County Soils SUNey map is included in Appendix C of this report Wetlands Inventory Map • There are no wetlands located on this site. Erosion Hazard and Landslide Hazard Area Map • The site is not located in a erosion or landslide hazard area Flow Control Applications Map • The site is located in a ConseNation Flow Control area per the 2005 King County Surface Water Design Manual Water Quality Applications Map • The site is located in the Basic Water Quality treatment area per the 2005 King County Surface Water Design Manual. 2 lask3. Field Inspection A site reconnaissance was performed on February 16, 2005 for the purpose of analyzing the proposed project site and its upstream and downstream corridors. The offsite drainage system was inspected V. mile downstream. These ten items were inspected during the field inspection per the 2005 King County Surface Water Design Manual. 1. Investigate ahy problems reported or observed during the resource review. • The culvert that was plugged in drainage complaint 96-1550 appears to be plugged again. 2. Locate all existing /potential problems constrictions or lack of capacity in the existing drainage system. • The existing drainage system appears to have adequate capacity. 3. Identify all existing/potential downstream drainage problems as defined in section 1.2.2.1. • The drainage complaints are included in Appendix E of this report Drainage complaints 1991-1132 and 1997-1301 were missing and not available. 4. Identify all existing/potential overtopping, scouring, band sloughing, or sedimentation. • None observed. 5. Identify significant destruction of aquatic habitat or organisms (e.g., severe siltation, bank erosion, or incision in a stream). • None observed. 6. Collect qualitative data features such as land use, impervious surfaces, topography, and soil types. • This information is included in Task 4 of this report 7. Collect information on pipe sizes, channel characteristics, drainage structures, and relevant critical areas (e.g., wetlands, streams, steep slopes). • This information is included in Task 4 of this report 8. Verify tributary basins delineated in Task 1. • The tributary basins were verified. 9. Contact neighboring property owners or residents in the area about past or existing drainage problems, and describe these in the report (optional). • No property owners were contacted 10. Note the date and weather conditions a the time of the inspection. • The site visit was conducted on February 16, 2005. The weather conditions were dry, 50 degrees Fahrenheit and clear and sunny. 3 Task 4. Drainage System Description and Problem Descriptions Please see Appendix 0 for downstream photos and off-site analysis drainage system table. The site currently drains from the west to the east The northwest 4.3 acres drains toward the adjacent property to the east The southeast 3.5 acres drain toward the drainage ditch located along 120th Avenue S.E. This area also receives runoff from approximately 2.9 acres to the west Surface water runoff that leaves the site enters a ditch along the west side of 120th Avenue S.E. It flows to the south to the intersection of SE 192nd Street and 120th Avenue S.E. There it enters a 12" storm drainage pipe and flows to a catch basin in 120th Avenue S.E. The runoff then flows to the east through 18" storm pipe at approximately 4% slope. The road continues down the hill and the pipes slopes increase to approximately 10%. The pipe size increases to 24" and the flow discharges to a half concrete pipe. The flow continues through a heavily vegetated swale toward a driveway. It appears that the runoff is supposed to flow through a concrete culvert This culvert is plugged and the runoff appears to be infiltrating in the ground. There is evidence that water has been flowed across the driveway and caused some erosion. One problem observed during the site visit was the ditch along the north side of 120th Avenue S.E. had some debris in it This is a minor problem and the ditch could be cleaned out easily to allow for better flow. The other problem observed was the plugged pipe that caused erosion across the driveway. This appears to have been a problem before and was mentioned in drainage complaint #96-1550. The offsite drainage complaints from King county are Included in Appendix E. 4 Task 5. Mitigation of Existing or Potential Problems The existing downstream problem that was observed was the erosion of the driveway described in Task 4. The developed site will not aggravate this existing problem because the site will also have Level 2 flow control. This will restrict the flow of the 2-year release to 50% of the pre-developed site. 5 APPENDIX A Vicinity Map SE 186TH ST SE 189TH LN SE 190TH LN SE 192ND ST SE 196TH ST w (I) ~ iE to ~ SE 188TH ST w (I) ~ iE o N VICINITY MAP KING COUNlY.

You are requesting approval for an adjustment from the 2005 King County Surface Water Design Manual (KCSWDM) Core Requirement No.1, Section 1.2.1, Discharge at the Natural Location. Our review of the information and a site visit provides the following findings: I. The proposed Jessie Glen subdivision is located between 116 th and 120th Avenues SE north ofSE 192 nd Street. The 49 lot, 7.7 acre, proposed Jessie Glen subdivision is filed under Land Use Services Division (LUSD) file number L05P0005. 2. The Jessie Glen subdivision is located in the Upper Soos Creek subbasin of the Soos Creek basin. The site is subject to the Conservation (level two) flow control and Basic water quality requirements of the 2005 KCSWDM. 3. The irregularly-shaped site consists of two separated rectangular-shaped areas connected by a unique 30-foot strip that provides continuity. The entire site and surrounding area gently slopes from west to east. The northwest rectangle abuts the east side of 116 th Avenue SE. Sheet flow from the northwest rectangle crosses its eastern property line onto the abutting properties. To the south, the southeast rectangle abuts the west side of 120 th Avenue SE. Based on topography, sheet flow from the southeast rectangle crosses its south property line onto the adjacent property. All excess now eventually recombines in the ditch on the west side of 120th Avenue SE and flows south. Upon reaching SE 192 nd Street, flows tum east toward Soos Creek. It appears that some upstream area would be tributary to the site. 4. The proposal is to collect most runoff from the northwest rectangle and direct it to the southeast rectangle where all site flows will enter a single detention and water quality facility locatcd at the eastern end of the site adjacent to 120th Avenue SE. From 120th Jessie GlenlL05V0052 September 22, 2005 Page 2 of3 A venue SE, the allowed release would then travel east on the north side of SE 192nd Street. Nuisance flows to adjoining properties would be largely eliminated. Only frontage improvements along I I 6th Avenue SE appear to be included in the conceptual drainage plan. 5. No decorative ponds or shallow wells have been identified that would be affected by the proposed diversion. 6. The Level One Downstream Analysis identified an apparent repeat of drainage complaint 1996-1550. At the downstream end of the conveyance path on the north side of SE 192 nd Street is a driveway culvert crossing for the residence at 19121 124th A venue SE. This driveway crossing is just prior to flow entering Soos Creek. It has been observed to be plugged and appears to need cleaning. This situation does not trigger the need for a higher level of flow control. 7. A consolidation offacilities for the proposed subdivision will be more economical in long term maintenance. . Based on these findings, we hereby approve this adjustment to allow the diversion of runoff to a single combined drainage facility draining to 120 th Avenue SE with the following conditions: I. The release rates for the detention facility will be based on the tributary area being directed to the facility. 2. The volume for the detention facility will be based on all flows directed to the facility at full development under current zoning. The allowed release rate will be reduced by any undetained flows that would bypass the proposed subdivision drainage facilities. The detention volume shall be sized using the Conservation flow control standard in the 2005 KCSWDM. A 10 to 20 percent volumetric factor of safety must be applied to all storm events requiring detention. The design Technical Information Report shall state the factor of safety selected and the basis of that determination. 3. Water quality facilities must be sized based on the entire proposed subdivision draining to the facilities including any required frontage improvements. 4. All onsite or offsite drainage facilities must be located in a public right-of-way, recreation space tract with easement or storm drainage tract dedicated to King County. 5. Additional storm drainage requirements identified by SEPA or the plat hearing review will apply to this project. The applicant retains all rights and privileges afforded in Section 1.4. If you have any further questions regarding this KCSWDM adjustment or the design requirements, please contact Mark Bergam at (206) 296-7270.

The adjustment is being requested based on the Preliminary Plat Application comment letter from Trisha Bull dated June 21, 2005. The proposed project encompasses approximately 7.7 acres and is located in unincorporated King County, on the East Hill of Kent More specifically, the project is located between 116th Avenue SE and 120th Avenue SE, just north of SE 192nd Stree~ and includes King County Tax Parcel Numbers 619840-0080, 619840-0100, 619840-0120, 619840-0140, and 619840-0320. The configuration of this project is somewhat unique as we are proposing two separate developed areas that are connected via a 30' wide parcel of land, which is proposed to be part of the required park area. See attached Preliminary Plat sheets for more detail. Stormwater drainage for the two separate proposed developed areas will be collected and conveyed to a detention pond as shown on the attached Preliminary Road and Drainage Plan. The adjustment to the Core Requirement #1 is being requested because we would like to combine the subbasins for the north and south sites into one post developed stormwater drainage facility. Ordinance 15052 dated May 26, 2005 for the 2005 King County Surface Water DeSign Manual describes Core Requirement #1 as follows: "Discharge at the natural location. All surface and storm water runoff from a project shall be discharged at the natural location so as not to be diverted onto, or away from, downstream properties. The manner in which runoff is discharged from the project site shall not create a significant adverse impact to downhill properties or drainage systems as specified in the discharge requirements of the Surface Water Design Manual.' The review criteria which will be used to evaluate this adjustment were also taken from Ordinance 15052 and are listed below in italics with a response addressed in bold: 33915 1 sl Way South Suite 200 Tel (253) 838 6113 Fax (253) 838 7104 Bothell (425) i.15 6144 www.esmcivil.com UU CiV:,l Engineering la1.u,an,in4 Project Management Puollc Wor"s 2005 Land Surveying Landscape Architecture Mr. Mark Bergam June 22, 2005 Page 2 (1) Produce a compensating or comparable result in the public interest, and The project proposes to direct stormwater drainage from two separate areas into one detention pond. The public community will benefit from this design because It will reduce the maintenance and operation activities to one detention pond Instead of two. (2) Meet this chapter's objective of safety, function, appearance, environmental protection and maintainability based on sound engineering judgement. Existing topography shows the north project site (Lots 1 -31 and respective roadways and tracts) draining to the east through adjoining private lots prior to reaching a ditch flowing south on the east side of 120th Avenue SE. Since the project site was originally heavily forested, most of the stormwater runoff would infiltrate prior to reaching the existing ditch. Therefore, with this adjustment, the Impact to the existing lots to the east will be minimal. The natural location for a stormwater detention facility for Lots 1 -31 would be along the east property line with a discharge of existing undeveloped stormwater flows through the existing lots to the east to ultimately reach the existing ditch along 120th Avenue SE. Routing the stormwater to the detention pond in Tract D provides a safer and more functional alternative due to the fact that stormwater drainage will not be directed through private properties. As mentioned In response to criteria (1), It is in the public Interest to limit maintenance to one detention pond. In addition, no adverse environmental Impacts will result from this adjustment of the stormwater discharge location. In summary, the proposed adjustment to the Core Requirement #1 is in the public interest and meets the objective of safety, function, appearance, environmental protection and maintainability based on our engineering judgment As requested, we are enclosing a completed Surface Water Design Manual Requirements/Standards Adjustment Request, three copies of sheets 1, 2, and 4 of the Preliminary Plat plans, one copy of each Certification and Transfer of Applicant Status forms, a copy of the Level One Downstream Analysis, an aerial photograph of the project site, courtesy of King County Imap, and a check for the current fee of $2,672.00.
