Site Location: The property is located to the south of SW 27`h Street, in the City of Renton, Washington. The site presently is undeveloped with wetlands along the southern border of Tract H. This project proposal is to develop roadway infrastructure and all the associated paving, utilities, storm drainage and landscaping improvements to serve this 17.32-acre site to accommodate approximately 16.33 acres of future office development. Design Criteria: The City of Renton utilizes a modified version of the 1990 King County Surface Water Design Manual (KC-SWDM). For this project the 2-, 10-, and 100-year, 24-hour storm events were evaluated using StormSHED 2G release 7.0.0.9. Stormwater detention, water quality and conveyance design will be addressed through the 1990 KC-SWDM as summarized below. Pond geometrics wil) be designed using the 2005 KC-SWDM.

Water quality wil) be provided via a permanent wetpond below the required (ive storage. The proposed system has been designed to provide sufficient capacity for the future office business park development. The runoff will leave the site at the pre-developed rates through an outlet in the wetpond and disperse into the existing 50-foot wetland buffer along the southern border of Tract H. Conclusion: The proposed stormwater management system for this project has been designed in accordance with regulatory criteria described above and consistent with sound engineering practice. This design has matched the pre-developed peak runoff and incorporated stormwater quality BMP's. Therefore, no significant adverse impacts to the stormwater management system are expected as a result of this proposed development.

The proposed project includes the development of the roadway infrastructure, adjacent to the future Boeing Longacres Office Park, with all associated roadway paving, utilities, storm drainage, and landscaping improvements to serve this 17.32-acre site. Stormwater treatment and detention are being provided through a wet detention pond system located in the southeast portion of the site (Tract H on Binding Site Plan), and has been designed to provide stormwater quantity and quality control for the proposed development. A general project vicinity map is also included in Appendix A as Figure 1. The topographic survey indicates that the existing site presently has earthen remains that stretch from Lot 29 to Lot 31, with an elevation range from 24 ft to 42 ft. The existing site is undeveloped with the exception of the mound of earthen remains, and an existing gravel and dirt roadway. The existing topography slopes down from the north to the south, with slopes ranging from 0.7% to 40°/0. Site vegetation consists of grasses, small deciduous trees, larger cedar and fir trees, blackberry bushes, and other vegetation. The King County Soil Survey of the Renton Quadrangle, King County, Washington (1972) shows soils in the vicinity of the site mapped as predominately Woodinville Silty Loam , (Wo) with traces of Newberg Silty Loam (Ng) and Puget Silty Clay Loam (Pu), see Appendix A - Figure 6. Wo and Pu are described as being poorly drained soils that have - engineering limitations due to a high seasonal water table and the high potential of flooding. The Ng soil is described as being a well drained soil, but still has engineering limitations due to its potentia) to flood. Considering all of the soils have engineering limitations associated with flooding, the curve number for the existing soils will be represented by the Hydrologic group D as a conservative approach to the quality of soils on-site. According to the FEMA Map, see Figure 8, the Flood Zone Designation for the site is primarily Zone X and Zone AE. The 100-year floodplain is located at an approximate elevation of 16 in Zone AE; however, according to the e-mail conversation between Ron Straka with the City of Renton and KPFF, between 4/8/05 and 4/11/05, for the Federal Reserve Building site, the FEMA 100-year floodplain elevation is 20.58 (NAVD 88) and the compensatory elevation is at an elevation of 19.18 (NAVD 88). As mentioned above, the compensatory storage elevation for the Federal Reserve Building site is 19.18 (NAVD 88), for the purposes of this report we assume the same for the Boeing Longacres Office Park Improvements. The existing site elevations for this site range from approximately 18 to 37. There are two areas with elevations less than 19.18. The first is along the southwest corner of Tract H and the other is at approximate station 24+00. Per our calculations, the total fill volume below an elevation of 19.18 for the proposed improvements is approximately 80 cf. Compensatory storage has been provided by the proposed pond in Tract H. The compensatory storage area will be connected to the PACLAND Job#50063002 Page 5 Storm Drainage Analysis Renton, WA floodplain via an overflow spillway (elevation 17.9) outletting into the wetland buffer south of Tract H; areas within the buffer disturbed during construction will be restored using native plant vegetation. The proposed stormwater detention pond is providing over 100,000 cf of what would be considered compensatory storage below an elevation of 19.18 (NAVD 88). Table 2 Existing Conditions Area Condition CN 17.32 Youn Underbrush (Pervious) 86 Discharge at Natura!(Existing) Location Stormwater presently discharges to the South Marsh Wetland "M" located to the south of Tract H. The same discharge point will be used in the site development. The City of Renton has indicated that installing a storm drainage discharge pipe within the buffer is allowed by their codes, and does not require a special permit. Please see the downstream analysis for more information. Soils Condifions Presently, there has not been a geotechnical study completed on-site; therefore, in-depth information concerning ground soils is not available. The site surface soils are classified by The United States Departments of Agriculture Soil Survey for King County, Washington, to be the Woodinville Silty Loam (Wo), Newbery Silty Loam (Ng) and Puget Silty Clay Loam (Pu), as described above. With regard to hydrology, these soils are described by the Natural Resources Conservation Service (NRCS) to be very susceptible to flooding, therefore, for design purposed the report will use the SCS Soil Hydrologic Group class „p „ Wells, Sepfic Tanks and Fuel Tanks Based upon field reconnaissance and the topographic survey, it appears that no fuel tanks, wells or septic tanks are presently located on the property. Proposed Development The proposed project includes the development of the supporting roadway infrastructure for the future 16.33 acre Boeing Longacres Office Park, which includes all the associated paving, utilities, storm drainage, and landscape improvements. Tabte 3 shows the break down of the proposed surface areas. Table 3 Pro osed Conditions Area Condition CN 14.85 Im ervious Surfaces 98 2.47 Irri ated Landscaping 90 PACLAND )ob#50063002 Page 6 Storm Drainage Analysis Renton, �NA In the developed condition, the newly constructed roadway will be an 875 LF extension of an existing 291 LF roadway, and will serve the future development of the Boeing Longacres Office Park. The impervious and pervious areas relating to stormwater calculations were assumed to be 85% impervious and 15% pervious for each lot, the roadway right-of-way was assumed to be 100°/o impervious, and the location of the wet detention pond, Tract H, was assumed to be 80°Jo impervious and 20% pervious. The stormwater runoff from each lot will be collected into catch basins located within the roadway, and will be conveyed to the wet detention pond located in Tract H. I I I . I ' • I As required by the City of Renton, storm drainage design for this project complies with the 1990 King County Surface Water Design Manual (KC-SWDM). For this proposed project, a full drainage review is required if one of the following criteria is met: 1.) the project is expected to cost more than $500,000 in construction fees, 2.) will replace more than 5,000 SF of on-site impervious area, 3.) abuts a floodplain, wetland, stream, lake, or sensitive area, per 1990 KC-SWDM Section 1.1.1. This project will require a full drainage review; therefore, all five core requirements and the applicable special requirements listed ` in the KC-SWDM will be met. These requirements are addressed below. i Core Requirement No.l: Discharge of the Natural Location: The drainage produced from ; the proposed project site must occur at the natural location. Response: The natural point of discharge for the property is to the existing wetlands located south of Tract H. The proposed project will outlet at a flow rate equal to or slightly less than the pre-developed flow rate; this will help maintain the existing hydrology of the wetlands; therefore, this requirement has been met. Core Requirement No.2: Off-site Analysis: Al! proposed projects must identify the upstream tributary drainage area and perform a downstream analysis, the level of analysis , required depending on the problem identified or predicted. __ Response: As stated in the off-site analysis, there is no significant off-site source of tributary runoff from the adjoining properties. This project will maintain the site's current runoff ' � characteristics; however, a downstream analysis was conducted considering the natural � ' point-of-discharge is a wetland that eventually drains to a Springbrook Creek located about Ya mile from the southeast corner of the site. i - Core Requirement No.3: Proposed project must provide runoff control to limit the developed condition peak rate of runoff to the existing peak rate for a specific design i storm event based on the proposed project site's existing runoff condition, and install biofiltration measure. Response: The King County Surface Water Design Manual allows post-development release rates to be at or below the 2-year, 10-year, 24-hour storm events; however, for the 100-year, 24-hour storm event, the release rate depends on the significance of downstream impacts. The proposed peak runoff for all the storm events is slightly less than the existing peak runoff due to the existence of a wetland. The project proposes to provide treatment of PACLAND 1ob#50063002 Page 7 Storm Drainage Analysis Renton, l-ti'A runoff from paved surfaces through the wetpool volume, with a 50°/o Factor of Safety added to the wetpool volume in lieu of the biofiltration system. Core Requirement No.4: Conveyance System: All new conveyance systems for a proposed project must be analyzed, designed, and constructed for existing tributary off-site runoff and developed on-site runoff from the proposed project. Response: All new pipe systems will be designed to convey the 25-year storm peak flow. An analysis will be performed to provide for an overflow route of the 100-year runoff event to prevent on-site flooding or erosion. A backflow analysis was also completed to ensure the conveyance capacities are appropriate. Core Requirement No.S: Erosion / Sedimentation Control Plan: All engineering plans for the proposed project that propose to construct new, or modify existing drainage facilities, must include a plan to provide all measures for the control of erosion and sedimentation during construction and to permanently stabilize soils exposed during construction. Response: Erosion and sediment control requirements, as outlined in the KC-SWDM, wil) be an integral part of the project documents. These measures include methods to reduce erosion of on-site site soils and to prevent sediments from inadvertently leaving the project site during construction. Permanent stabilization design is also included. Special requiremenf #5: Special Water Qual ity Controls Response: This site does meet the requirements to apply special water quality controls to all stormwater runoff generated by the proposed development. Due to the natural point- of-discharge being a wetland, a wetpond will be utilized to treat the proposed development's runoff prior to discharging into the wetland buffer in accordance with the 1990 King County Surface Water Design Manual. In lieu of adding a biofiltration system to the water quality control measures, a 50% Factor of Safety was added to the wetpool volume by request from the City of Renton. / In accordance with the 1990 KC-SWDM and to verify the suitability of the on-site improvements, a level one analysis was performed. This involves studying the watershed conveyance path approximately Y mile along the upstream and downstream of the site to check for conditions, such as flooding or excessive erosion, that might indicate that additional standards are required. Downstream Analysis According to USGS Maps and the King County GIS System, Springbrook Creek exists approximately Ya mile downstream from the southeast corner of the site. South Marsh Wetland "M" eventually drains to Springbrook Creek, since this is the natural runoff location of the existing site. Since the proposed detention wetpond will release into the wetland at or below the pre-developed peak release rates, the proposed development will not have an adverse impact on the downstream system. PACLAND Job#50063002 Page 8 Storm Drainage Analysis Renton, ��VA Upstream Analysis The project site does not receive a significant amount of upstream runoff. The Union Pacific Railway produces runoff along the western edge of the site, which is routed via a ditch that runs parallel with the site and eventually drains into South Marsh Wetland "M". No adverse impact from upstream runoff is expected. The topography on-site appears to be somewhat of a high point, therefore, there is little off-site drainage contributing to the site. I , � Hydrologic Modeling Method Hydrologic analysis of the project area was performed using the computer-modeling program StormSHED 2G, release 7.0.0.9, which uses the Santa Barbara Urban Hydrograph (SBUH) methodology. The program effectively models pre-developed and developed runoff conditions using hydrographs for each basin. Given a specified design storm (precipitation value) and its associated distribution, the computer model calculates runoff hydrographs in terms of peak rates and total volume based on the approximated characteristics of the basin (i.e. area, curve number (CN), time of concentration (Tc), etc.). The StormSHED software program has been designed to enable the user to route the hydrographs generated from the basin analysis through a proposed conveyance system and/or detention facility. The modeled peak flows and volumes were used in the analysis of the proposed drainage system. These flows were used to size the flow control outlet structure and detention facility. For the proposed project, the 2-year, 10-year and 100-year, 24-hour design storm events were analyzed in accordance with the King County requirements. The proposed system was developed to mitigate peak runoff rates with one detention wetpond to serve the site. The calculated detention facility volume capacity was increased by 30% for the 2-year and 10-year storm events, in accordance with the 1990 KC-SWDM Section 1 .2.3. The design volume for the live storage in the wetpond, according to the size of the development, is 58,126 cf. A detention pond with dimensions of 130'x130'x2.5' and 3:1 side slopes was used in the StormSHED for the calculations. The constructed detention wetpond will contain two cells, in accordance with 2005 KC-SWDM Section 6.4.1.2; the two celled pond was modeled as a single unit in StormSHED due to both ponds being hydraulically connected through a berm with a top elevation of 14.5, in accordance with the 1990 KC-SWDM. The design volume for the live storage will be increased by a factor of safety of 30%, and will be increased proportionately in 1-foot increments without impacting the depth of storage. The required volume calculated by StormSHED is 44,464 cf and the required volume, including the Factor of Safety, is 57,803 cf, and the provided volume is 58,126 cf. To meet the required factor of safety, between contours 15.5 ft and 22 ft, the interior pond slopes will be graded with a 2:1 (H:V) slope, and a fence must be constructed around the pond according to the 2005 KC-SWDM. Two internal Lock-Block walls, with dimensions of 48'x2.5'x2.5' and 53'x2.5'x2.5,' were added to the pond to lengthen the hydraulic flowpath in the pond. The Lock-Block walls will be between elevations 15.5 and 16.8, see Figure 7 for specifications of the Lock-Block. PACLAND Job#50063002 Page 9 Storm Drainage Analysis Renton, WA A 48" storm drain manhole will comprise the flow control structure, which will be located at the southwestern corner of Tract H, and will outlet into South Marsh Wetland "M." A multiple orifice system will allow the pond to outlet into the wetlands at different intervals, with the lowest orifice at elevation 13.50 with a diameter of 8.1 inches, the second orifice will be at an elevation of 16.85 with a diameter of 10.3 inches, and the third orifice will be at an elevation of 17.4 with a diameter of 9.8 inches. The invert elevation of the 18 inch outlet pipe will be set at 15.5, and the rim elevation of the structure will be approximately 21.0, see the Flow Contro) Structure Detail in Appendix 6. Water Quality The wetpond must contain a Permanent Pool Volume (PPV) equal to or greater than 1/3 the precipitation value of the 2-year, 24-hour event, equaling 25,665 cf, utilizing the 1990 KC-SWDM design criteria. With regard to providing both a biofiltration swale and a wetpond to satisfy Special Requirement #5, the City of Renton allowed the wetpond PPV to incorporate a 50% factor of safety in lieu of a biofiltration swale, though it was not stated in the manual; therefore, the required PPV must be equal to or greater than 38,485 cf. The wetpond will provide a total PPV of 53,036 cf between elevations 11 .0 and 15.5. Cell 1 contains 10,815 cf and Cell 2 contains 42,221 cf of the total PPV, Cell 1 contains 28% of the required PPV satisfying the requirement of the 1990 KC-SWDM. Cel! 1 is providing 1,056 cf of sediment storage between elevations 10.0 and 11.0, in accordance with the 2005 KC-SWDM Section 6.4. The design surface area at elevation 15.5 is equal to 21,714 SF, in accordance with the 1990 KC-SWDM Section 1.3.5, which states the surface area at the top of dead storage must be equal to 1% of the impervious area contributing to the detention wetpond; therefore, the required surface area is 6,469 SF. To further facilitate stormwater treatment, the flowpath length to width ratio must be equal to or greater than 3:1. In order to maintain this ratio, two additional Lock-Block walls were added to lengthen the hydraulic flowpath to 3.33:1 . After treatment, the runoff will leave the site by out-falling into the wetland buffer south of Tract H. Calculations for sizing the wetpond are included in Appendix 6. The following table summarizes the Pre-Developed and Post-Developed runoff peak rates for the wet detention pond: Table 5: Stormwater Detention Wetpond Rainfall Event Pre-developed Site (cfs) Developed Site(cfs) Release Rates (cfs) 2-year 1.995 6.698 1.991 10-year 4.334 10.259 4.326 100-year 7.429 14.484 7.407 Provided Dead Storage/Permanent Pool Volume: 53,036 cf (1.24 ac-ft) Required Dead Storage/Permanent Pool Volume: 38, 485 cf(0.884 ac-ft) Provided Live Storage Detention Volume: 58, 126 cf(1.337 ac-ft) Required Live Storage Detention Volume: 57, 803 cf (1.021 ac-ft) PACLAN D Job#50063002 Page 10 Storm Drainage Analysis Renton, WA Table 6: Pro osed Pond Stage Storage Elevation Area Volume FT SF CF Cell1 Cell2 Total Incremental Cumulative ' Sediment 10 893 0 893 Storage 11 1218 0 1218 1056 1056 11.5 1445 6445 7890 2277 2277 12 1671 7224 8895 4196 6473 Dead 13 2197 8842 11039 9967 16440 Storage 14 2803 10539 13342 12191 28631 � (11.0-15.5) 15 Combined Combined 16407 14875 43505 15.5 Combined Combined 21714 9530 53036 Total Dead Storage 16 Combined Combined 22650 11091 11091 Live 16.75 Combined Combined 24608 17722 28813 2-yr,24-hr Storage 17 Combined Combined 24891 6187 35000 (15.5-17.9) 17.3 Combined Combined 25482 7556 42556 10-yr,24-hr 17.9 Combined Combined 26445 15578 58134 100-yr,24-hr Conveyance For conveyance design, Uniform Flow Analysis utilizing Manning's equation was employed with a Manning's "n" value of 0.014.

The stormwater volume quantities used were calculated from the StormSHED software using the SBUH methodology. Once the conveyance system was appropriately sized for the flo�vrates of the 25-year, 24- hour storm event, a backwater analysis was performed to analyze the capacity of the 25- year and 100-year, 24-hour storm events. The Backwater Calculation Sheet used the backwater analysis method, according to the 1990 KC-SWDM Section 4.3.4, to determine the head losses and headwater elevations for each pipe segment, see Appendix B for Backwater Calculation Sheet. According to the 1990 KC-SWDM requirements, the backwater analysis must demonstrate that the proposed conveyance system can provide a minimum of 0.5' of freeboard between the headwater surface and the rim elevation for the 25-year, 24-hour storm event; however, overtopping is permissible for the 100-year, 24- hour storm event, but does not occur within the proposed development. PACLAND Job#50063002 Page 11 Storm Drainage Analysis Renton, WA 100-Year Flood/Overflow Condition The stormwater system for this project has been designed to address all storm events in accordance with design criteria described previously. In the event of a storm larger than the 100-yr, 24-hr event, the system may overflow into the existing wetland buffer. Based on our review, we anticipate the overflow of the stormwater drainage system would allow water to discharge to the existing wetland south of the proposed development via an emergency overflow spillway, see Sheet CR-2.4 for the exact location of the spillway. � � � � All erosion and sediment control measures shall be governed by the requirements of King County and the City of Renton, where a 21,354 SF sedimentation pond is required with a orifice of 1.57 SF. A temporary erosion and sedimentation control plan has been prepared to assist the contractor in complying with these requirements. See the attached TESC plan in Appendix C. 1. Construction Sequence And Procedure The proposed development includes an erosion/sedimentation control plan designed to prevent sediment-laden run-off from leaving the site during construction. The erosion potential of the site is influenced by four major factors: soil characteristics, vegetative cover, topography, and climate. Erosion/sedimentation control is achieved by a combination of structural measures, cover measures, and construction practices that are tailored to fit the specific site. Prior to the start of any grading activity upon the site, all erosion control measures, including installation of a stabilized constriction entrance, shall be installed in accordance with the construction documents. The best construction practice will be employed to properly clear and grade the site and to schedule construction activities. The planned construction sequence for the construction of the site is as follows: 1 . Flag and stake clearing limits. 2. Arrange and attend a preconstruction meeting with the City of Renton. 3. Install perimeter erosion control features (silt fence, construction entrance etc.) 4. Field locate all utilities. 5. Clear/demo and grub site. 6. Grade the site. 7. Install sanitary sewers, storm, water, and other site utilities; provide CB inlet protection at the new inlet locations. 8. Thoroughly clean new storm system upon completion of paving to prevent sediment from leaving the site. 9. Install wetland seed mix within pond or seed to a healthy stand of grass prior to bringing "on-line". PACLAND Job#50063002 Page 12 Storm Drainage Analysis Renton, 1�1.�A 10. Remove temporary erosion control facility upon stabilization of entire project site, , as approved by governing jurisdiction and project engineer. ' 2. Trapping Sediment Structural control measures will be used to reduce erosion and retain sediment on the construction site. The control measures will be selected to fit specific site and seasonal conditions. '� The following structural items will be used to control erosion and sedimentation processes: ', • Stabilized construction entrance ' • Temporary gravel construction entrance ', • Filter fabric fences '! • Cover measures �I • Temporary swale and sediment pond , Weekly inspection of the erosion control measures will be required during construction. Any sediment buildup shall be removed and disposed off site. Vehicle tracking of mud off-site shall be avoided. Installation of a gravel construction entrance will be installed at a location to enter the site. The entrances are a minimum requirement and may be supplemented if tracking of mud onto public streets becomes excessive. In the event that mud is tracked off site, it shall be swept up and disposed off site on a daily basis. Depending on the amount of tracked mud, a vehicle road sweeper , may be required. Because vegetative cover is the most important form of erosion control, construction ' practices must adhere to stringent cover requirements. More specifically, the contractor will '', not be allowed to leave soils open for more than 7 days and, in some cases, immediate i seeding will be required. During the period of November lst through April 30`", all ' disturbed soil areas will be stabilized within seven days. Areas next to paved areas may be armored with crushed rock subbase in place of other stabilizing measures. A sediment trapping pond was designed according to the 1990 KC-SWDM Section 5.4.5.2- 2. The sediment trapping pond will be designed for the 10-year, 24-hour storm event since the pond will be discharging into a sensitive area such as the wetlands. The flowrate used for the 10-year, 24-hour storm event was 10.25 cfs; the provided surface area of the temporary sedimentation pond is 24,600 SF, the required orifice diameter is 1 .35 in, and the minimum depth of the pond is 3.5 feet from the top of the riser to the battom of the pond.
