S lJ LJ! N G E N _ j6_. Job No.1123-002-004 With this letter and accompanying information, ESM Consulting Engineers is requesting the scheduling of a Pre -application Meeting with the County to discuss the future development of approximately 7.7 acres, located in unincorporated King County, on the East Hill of Kent The project is more specifically located between 1161h Avenue SE and 120�h Avenue SE, just north of SE 192Ild Street, and includes King County Tax Parcel Numbers 6198400- 0080, 619840-0100, 619840-0120, 619840-0140, and 619840-0320, 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 property has a Comprehensive Plan designation of Urban Residential, Medium (Single Family, 4-12 Units per Acre) and a zoning designation of R-6 (Single Family Residential, 6 Units per Acre). The conceptual layout depicts a total of 49 lots with appropriate areas for roads, recreation space and a stormwater detention pond. We understand that the proposed density exceeds the base density, and expect our client will obtain density credits for use in this project The configuration of this project is somewhat unique as we are proposing two separate developed areas that are to be connected via a 30' wide parcel of land, which is proposed to be part of the required park area. Access is proposed from 116"' Avenue SE into the northern portion of the development The southern portion of the project will gain access to SE 192Id Street through the approved preliminary plat of Sharmila Rathinam (KCLU L04S0003), and will extend the road to the east to connect with 120'h Avenue SE. The northern portion of this road is proposed to be a half -street at this time, as the property to the north is under -developed and is likely to be further developed in the future. 720 South 3481h Street Tel (253) 838 6113 $othell 1425) 415 6144 Federal Way.

B-12 Job#A4-366 Dear Ty, This letter describes my findings regarding jurisdictional wetlands, streams and buffers on the proposed "Jessie Glen" subdivision located off 1161h Avenue SW in unincorporated King County, Washington (the "site"). Specifically, the 7.7 acre site is an irregular shaped combination of five (5) parcels (Parcels #619840-0080, #619840-0100, #619840-0120, #619840-0140, and #€619840-0320) located between 1161h Avenue SE and 120th Avenue SW in the SW '14 of Section 33, Township 23 North, Range 5 East of the Willamette Meridian. The site is generally located within a suburban area surrounded by residential development. A Sewall Wetland Consulting, Inc. Company The Herbrand Co. -Jessie Glen/#A4-366 B-I2 Wetland Consulting, Inc. December 14, 2004 Page 2 The site includes several existing single family homes with associated landscaping, lawns gravel driveways, and scattered outbuildings. Portions of the site have immature (20- 45yrs old) deciduous forest covering them. No wetlands, streams or associated wetland or stream buffers were found on the site. The proposed project is the construction of a 49 lot subdivision with associated road, and stormwater facilities. METHODS On December 7, 2004, I inspected the site for jurisdictional wetlands and streams using methodology described in the Washington State Wetlands Identification Manual (WADOE, March 1997). This is the methodology currently recognized by King County and the State of Washington for wetland determinations and delineations. The Washington State Wetlands Identification Manual as well as the 1987 Federal Manual requires the use of the three -parameter approach in identifying and delineating wetlands. A wetland should support a predominance of hydrophytic vegetation, have hydric soils and display wetland hydrology. To be considered hydrophytic vegetation, over 50% of the dominant species in an area must have an indicator status of facultative (FAC), facultative wetland (FACW), or obligate wetland (OBL), according to the National List of Plant Species That Occur in Wetlands: Northwest (Region 9) (Reed, 1988). A hydric soil is "a soil that is saturated, flooded, or ponded long enough during the growing season to develop anaerobic conditions in the upper part." Anaerobic conditions are indicated in the field by soils with low chromas (2 or less), as determined by using the Munsell Soil Color Charts; iron oxide mottles; hydrogen sulfide odor and other indicators. Generally, wetland hydrology is defined by inundation or saturation to the surface for a consecutive period of 12.5% or greater of growing season. Areas that contain indicators of wetland hydrology between 5%-12.5% of the growing season may or may not be wetlands depending upon other indicators. Field indicators include visual observation of soil inundation, saturation, oxidized rhizospheres, water marks on trees or other fixed objects, drift lines, etc. Under normal circumstances, indicators of all three parameters will be present in wetland areas. OBSERVATIONS Prior to visiting the site a review of existing inventories that included the area of the site was completed. The inventories reviewed included the Soil Survey of King County, Washington, the National Wetlands Inventory Map (NWI), and the King County Wetland Inventory and iMap website. There are no wetlands, streams or hydric soils mapped for the site. The Herbrand Co. - Jessie Glenl#A4-366 B-12 Wetland Consulting, Inc. December 14, 2004 Page 3 Field Observations The portions of the site that are not already developed with single family homes and associated lawn, landscaping and driveways consists primarily of deciduous forest on the east, and on the north, an area of mixed forest and shrubs and small saplings on the north. The eastern forested area is a mix of alder, big leaf maple, scattered hemlock, salmonberry, Indian plum, sword fern and Himalayan blackberry. Soil pits excavated within the site revealed a well drained gravelly soil with a 1"4' A - horizon of I OYR 3/2 loam over a B-horizon of IOYR 3/4-3/6 gravelly loam. No hydric soil indicators were noted, and excavated test pits on the site that were 6' deep were dry to the bottom. No indication of wetland hydrology is present on the site. The two northern parcels include a forested area on the extreme north, and a shrub area just south of that parcel. The forested area includes a mixed third growth forested area with a mix of Douglas fir, big leaf maple, red alder, sword fern, Indian plum, hazelnut and salmonberry. Soils are dry with high chroma soils colors and hydric soil indicators. The shrub area contains large thickets of Himalayan blackberry as well as scattered cherry, alder, and Indian plum. Several small (100sf-400sf) depressions are located within some tire rutted areas where vehicles and debris have been driven and stored. Some scattered patches of buttercup were found in these areas but no evidence of wetland soils or hydrology. Soils were similar to other areas of the site previously described. Off -site Areas I inspected the area of off -site forest to the north of proposed Lot 32 (see "Jessie Glen Conceptual Site Plan — ESM Consulting Engineers, Inc. 11/5/04) for wetlands with the landowner's permission. This area has several large cottonwoods as well as some red - osier dogwood which looked like a potential wetland area. However, soil pits excavated within this area revealed only moist, non-hydric soils not meeting wetland criteria. I also inspected the area to the south of the site in just south of proposed lots 33, 36, & 37-41. This area has a subdivision proposed on it (KCLU L04SO003). Some very small depressions within old fill were noted with wetland flags on this site. Only one, just south of Lot 39 appeared to have any evidence of wetland hydrology or soils. This area is a small (approximately 500sf) area of scrub -shrub wetland. Since this wetland is <2,500sf in size it would not be regulated by the County within the urban area. Conclusion There are no jurisdictional wetlands, streams or buffers on the Jessie Glen site. The Herbrand Co. -Jessie Glen/#,44-366 B-12 Wetland Consulting, Inc.

To approve the desgin, I need to see some calculations for the access intersection of 116th Avenue SE. The intersection needs to be illuminated to an average of 1.5 footcandles with an averge/minimum uniformity of 3:1. Mr. Singh should be able to get this information from Jim Kennedy of PSE, their PSE contact.

This assumes the facility will be full due to plugged orifices or high inflows; the primary overflow is intended to protect. against breaching of a pond embankment (or overflows of the upstream conveyance system, in the case of a detention tank or vault)_ The design must provide controlled discharge directly into the downstream conveyance system or another acceptable discharge point. A secondary inlet to the control structurc must be provided in ponds as additional protection against overtopping should the inlet pipe to the control structure become plugged. A grated opening ("jailhouse window") in the control structure manhole functions as a weir (see Figure 5.3.1.B, p. 5-27) when used as a secondary inlet. Note: The maximum circumferential length of this opening shall not exceed one-half the control structure circumference. The "birdcage" overflow structure as shown in Figure 5.3.1.0 (p. 5-28) may also be used as a secondary inlet, Emergency Overflow Spillway 1. In addition to the above overflow requirements, ponds must have an emergency overflow spillway sized to pass the 100-year, 15-minute developed peak flow in the event of total control structure failure (e.g., blockage oCtbe control structure outlet pipe) or extreme inflows. Emergency overflow spillways arc intended to control the location of pond overtopping and direct overflows back into the downstream conveyance system or other acceptable discharge point, Emergency overflow spillways must be provided for ponds with constructed berms over 2 feet in height, or for ponds located on grades in excess of 5%. As an option for ponds with berms less than 2 feet in height and located at grades less than 5%, emergency overflow may be provided by an emergency overflow structure, such as a Type I1 manhole fitted with a birdcage as shown in Figure 5.3.1.0 (p. 5-28). The emergency overflow structure must be designed to pass the 100-year developed peak flow, with a minimum 6 inches of freeboard, directly to the downstream conveyance system or another acceptable discharge point. Where an emergency overflow spillway would discharge to a slope steeper than 15%, consideration should be given to providing an emergency overflow structure in addition to the spillway. 3. The emergency overflow spillway shall be armored with riprap in conformance with Table 4.22.A. The spillway shall be armored full width, beginning at a point midway across the berm embankment and extending downstream to where emergency overflows re-enter the conveyance system (see Figure 53.1.8, p_ 5-27)_ 4. Design of emergency overflow spillways requires the analysis of a broad -crested trapezoidal weir as described in Section 5.3.12 (p. 5--30). Either one of the weir sections shown in Figure 5.3,1.E (p. 5-27) may be used. Access Requirements 1. Maintenance access road(s) shall be provided to the control structure and other drainage structures associated with the pond (e.g., inlet, emergency overflow or bypass structures). Manhole and catch basin lids must be in or at the edge of the access road and at least three feet from a property line. Rims shall be set at the access road grade. 2. An access ramp is required for removal of sediment with a trackhoe and truck. The ramp must extend to the pond bottom if the pond bottom is greater than 1500 square feet (measured without the ramp) and it may end at an elevation 4 feet above the pond bottom, if the pond bottom is less than 1,500 square feet (measured without the ramp), provided the pond side slopes are 3:1 or flatter. Intent: On large, deep ponds, truck access to the pond bottom via an access ramp is necessary so loading can be done in the pond bottom. On small deep ponds, the truck can remain on the ramp for loading.

April 13, 2006 Page 2 3) Specify the lengths, critical cross sections and slopes of every ditch and swale 4) Revise the existing drainage map and table describing it to show and describe As discussed in the March 15, 2006 meeting, the information requested above is not necessary for the design of this project. As requested in the meeting, an exhibit has been prepared that shows the existing drainage basins upstream of the proposed CB #31 to determine the approximate capacity of the existing drainage system along SE 192"d Street Please insert the attached existing basins exhibit and a table summarizing the peak flows at the end of Section 3 of the TIR. B. The current backwater analysis and downstream analysis lack sufficient details to determine whether or not the tailwater elevation at proposed CB#31 is reasonable. We need to know whether or not this tailwater will have unacceptable adverse affects on the pond's storage or the existing upstream/downstream drainage system along SE 192"d Street. Please modify the offsite 100-year undetained backwater analysis and downstream analysis so it includes the following; 1) A basin map and calculations for the following: a) Drainage entering proposed CB#31 from the west (along SE 192"d Street). b) For the existing CB immediately to the east of proposed CB#31, show and determine the flows entering this CB from the north. 2) For the drainage system within two CB's east and west of CB#31 (along the northern side of SE 192"d Street) map and specify the pipe sizes, pipe invert elevations, pipe lengths, pipe materials and CB rim elevations. As discussed in the March 15, 2006 meeting, the information requested above is not necessary for the design of this project Plan sheet 8 has been revised to show the pipe sizes, pipe invert elevations, pipe lengths, and CB rim elevations for one CB east and west of CB #31. C. Design the pond's overflow and (secondary) emergency overflow per SWDM pages 5-19, 5-27, 5-28, 5-30 and 5-48. Address the following in these designs: 1) Clarify where the 100-year design flow rate came from. The 100-year 15-minute design flow rate of 9.34 cubic feet per second was used for the pond overflow calculations. This Mr. Ted Cooper, P.E. April 13, 2006 Page 3 flow rate is mentioned in the Overflow Calculations and the KCRTS printout is attached following the calculations page. 2) Design the overflow riser pipe (in the control structure) using the riser curves (SWDM page 5-48). Determine the overflow water surface elevation for the 1 00-year storm flow rate. As requested, using the riser curves and the 100-year 15- minute storm with a flow rate of 9.34 cubic feet per second, the overflow riser pipe has been revised on plan sheet 13 to have a 21 inch diameter with 0.67 feet of head. The overflow water surface elevation calculation for the 100-year storm flow rate is shown in the Overflow Calculations in Section 4. 3) Design the size of the vertical bar grate opening for the control structure using a weir equation. Subtract the widths of the bars to get its effective width. The grate's maximum water surface elevation for the 100-year storm must be less than or equal to that of the overflow riser. As discussed in the meeting on March 16, 2006, the impact of the bars width to the overflow water surface elevation is negligible. The grate's maximum water surface elevation for the 100-year 15-minute storm is set equal to that of the overflow riser. 4) Set the overflow elevation of the ponds (secondary) emergency overflow (or birdcage per SWDM page 5-28) at or above the riser's 100-year design water surface elevation. As shown in the TIR Section 4, Overflow Calculations, the emergency overflow elevation of 502.49 is above the riser elevation of 501.75. D. Modify the bond quantities sheets for any changes. The bond quantities have been modified as requested. Please replace the Site Improvement Bond Quantity Worksheet in Section 9 of the TIR with the attached revised version. 5_ Please make the following changes to plan sheet 3 and all other affected plan sheets: A. Modify the part of the `Tract E" PAT roadway that serves 3-lots so it meets minor access roadway standards (per KCRS 2.09B). Notice the 25'-radii required at the entrance. Mr, Ted Cooper, P.E. April 13, 2006 Page 4 This comment was revised on March 20, 2006 to read as follows: A. Modify the part of the "Tract E" PAT roadway that serves 3-lots so it meets minor access roadway standards (per KCRS 2.09B). Notice the 25'-radii required at the entrance. Use one of the following methods to provide access to Lots 4, 5 and 6- 1) Get an approved variance (to KCRS 3.01 C.3.a.) that will allow these three lots to be served by a JUD. If all 3-lots use a common driveway stub to access "Road A", then an access easement across Lot 4 (for a JUD) won't reduce the number of lots served by this driveway stub to 2. 2) Provide two adjacent 2o'-wide pipe stem lot extensions to serve these lots. One pipe stem would have a JUD serving 2-lots. The other one would have a single driveway. Driveways must be centered in the pipe stems. 3) Use a single access roadway PAT long enough to serve all 3-lots and a JUD where this roadway only serves 2-lots. A PAT must meet the same roadway design standards as a minor access roadway (per KCRS 2.09B), "Tract E" was revised using method 2). B. Where the `Tract E" roadway serves 2-lots it can be a joint -use driveway (see KCRS 3.01 C 3.a). See response to the revised part A of this comment C. Please relocate the two 16-box mailbox units on "Road A" to north of the common property line for lots 25 and 26, as approved by the U.S Postmaster. The two 16-box mailbox units have been relocated as requested. D. Correct the sheet referenced for all mailbox details. It should be DT-04. The sheet references have been corrected. E Show, dimension and label all necessary drainage and utility easements for each proposed lot Outside of the R/W, a1/ lot drain pipes serving more than one lot must be in a drainage easement The plan sheets have been updated to show the requested easements. 6. Modify all of the sidewalk ramps as follows: Mr. Ted Cooper, P.E. April 13, 2006 Page 5 A. Design them per the details on sheet DT-02. B. Locate all proposed sidewalk easements 1'-behind the sidewalks. The sidewalk ramps have been revised as requested and as discussed in the March 15, 2006 meeting. 7. At all mailboxes, widen the proposed sidewalk easements so each is 1'-back of the sidewalk widening. The easements have been revised as requested. 8. Provide an enlarged detail for the roadway and sidewalk improvements at the southern end of `Tract B" as follows: A. Dimension the location of the northern rolled curb so it is centered 12'- north of the "Road A" centerline. This comment was revised on March 20, 2006 to read as follows: A. Adjacent to the southern boundary of 'Tract B" use a standard concrete pedestrian ramp that matches the one opposite it. Label this ramp as `TEMPORARY" because it may need to be relocated for future roadway widening. Where the pavement is wider than that of the half -street, separate the widened area from the half -street pavement width with a fogline stripe. The revised comment has been incorporated on plan sheet 5. B. Across the frontage of `Tract B" maintain the proposed half -street width and connect the roadway to the ramp with a temporary 5'-wide ACP walkway. See response to the revised Part A of this comment C. Locate the "Road A" northern R/W line 20'-north of the roadway centerline. This is needed to place the R/W line 1'north of the ramps 6'- wide sidewalk (per sheet DT-02). The northern R/W line has been located as requested. 9. Please make the following changes to plan sheet 4: A. Specify that all 12"-diameter pipes must have smooth (not corrugated) linings between CB#19 and CB#22 and between CB#20 and CB#21. This is necessary to meet the minimum 3-fps full -flow requirement (SWDM page 4-11). Mr. Ted Cooper, P.E. April 13, 2006 Page 6 Drainage Note #12 that has been added to plan sheet 13 incorporates the requested smooth lining for all storm drainage PVC pipe. B. Make the following changes to the profile of CB#12. 1) Raise the invert of the 18"-pipe so its invert is clearly within 5'-0" of this CB's rim (as required by KCRS DWG 2-003, Note 7). Otherwise, this CB mast be changed from a TYPE 1 to a TYPE 2. This is strictly enforced by our construction inspectors. 2) Add the missing 12"-pipe and its invert elevation. The revisions have been made as requested. 10. On plan sheets 4 and 5, per the Postmaster's approval, show and specify the locations of all new, proposed and relocated mailboxes. Mailbox locations belong on these roadway sheets. This comment was resolved in the March 15, 2006 meeting. The existing mailboxes that are being relocated and the new locations are shown on plan sheets 4 and 6. 11. Please make the following changes to plan sheet 5: A. Please remove CB#1 A from the pond tract because it isn't needed. As discussed in the March 15, 2006 meeting, this catch basin is required. B. At "Road A" STA 35+58 (101T) place a CB with its rim low enough to drain the lowest point along the northern side of this roadway. Add a plan note that says to grade the R/W along the northern side of "Road A" to drain to this CB. This comment was revised on March 20, 2006 to read as follows: B. At "Road A" STA 35+58 (101T) show a CB with a rim low enough to drain the lowest point along the northern side of this roadway. Add a plan note stating that this CB may be omitted if approved by the LUIS inspector. The CB and plan note have been provided as requested. 12. Please make the following changes to plan sheet 6. Mr. Ted Cooper, P.E. April 13, 2006 Page 7 A. in the `Tract A" detail, specify the all 12"-pipes must have smooth (not corrugated) linings (to provide the 3-1ps full -flow velocity required on SWDM pg 4-11). See response to comment #9.A. 13. Please make the following changes to plan sheet 8: A. Provide a plan view (to scale) of CB#29 showing a revised design that it is physically large enough to accommodate both inlet pipes and the steps. A 487-diameter CB isn't large enough to accommodate the angle between the two inlet pipes. On KCRS DWG NO. 2-005, in Note 5, notice the required knockout sizes and the required spacing between them. Either a larger CB or an increased angle between these pipes is needed. CB#29 has been revised to show a 5411-diameter CB. A plan view of CB#29 has been provided as requested on plan sheet 13. B. For all existing pipes that will connect to CB #31 provide the pipe data (i.e., materials, diameters, invert elevations, slopes). Also, please verify that the pipe show with a 2W-diameter actually has this non-standard diameter. The information has been provided as requested. The pipes shown as 20"-diameter have been verified and revised to show 18% diameter. 14. Please make the following changes to plan sheet 10: A. Correct the labeling of both CB#28 and CB#29 and the sheets referenced for their details. The information has been corrected as requested. B. Install the pond gravity drain pipe, as required by SWDM item 7 on pages 6-75 and 6-100. It is possible to drain the pond with a gravity drain by only lowering the inverts of all pipe inverts at CB#29 and CB#30. The pipe run between CB#29 and CB#31 would need to have roughly a 0.5% slope (see minimum allowable pipe slope requirements on SWDM page 4-11). This gravity drain pipe could be connected directly to proposed CB#29. Its control valve should be located within the pond trace As discussed in the March 15, 2006 meeting, the gravity drain pipe is not required for this project Mr. Ted Cooper, P.E. April 13, 2006 Page 8 C. We recommend replacing the pond's overflow emergency spillway with a "birdcage" structure that is located immediately downstream of the control structure. it would also have to be as close as possible to the access road. This would have the following benefits: 1) It may eliminate the need to upsize CB#29 just to physically accommodate its inlet pipes. 2) The control valve for the gravity drain pipe could be located inside this structure. 3) It should eliminate the possibility of R/W ponding and erosion from drainage flowing over the emergency overflow. 4) It would be more compatible with future R/W improvements and more aesthetically pleasing_ As discussed in the March 15, 2006 meeting, the pond's overflow emergency spillway meets SWDM requirements and will remain. D. Please notice that a CB with a FROP-T (CB#1A) isn't needed (or desirable) upstream of the pond. If you propose to keep it, provide its design details on the plans. See response to comment #11.A 15. Please make the following changes to plan sheet 11: A In al/ cross sections, replace the words "GRANULAR SUB BASE" with the words "CRUSHED SURFACING BASE COURSE' We don't have specifications for "GRANULAR SUB BASE". B. Eliminate "APPROX." from the dimensioning of the lanes adjacent to the site, for 116'1' Ave SE and 120'h Ave SE C. In the cross section for 116"' Ave SE change "CRUSHED ROACK BASF COURSE" to "CRUSHED SURFACING BASE COURSE", a standard item. D. in "15' POND ACCESS ROAD SECTION D-D" replace the "CRUSHED ROCK" with "1-1 /2 INCHES CSTC OVER 5" CSBC" per SWDM page 5-20 (Construction of Access Roads). F In "ROAD A(SUBACCESSS 112 STREET) specify a R/W width of 38' at "Tract B" (approx. STA 32+47 to STA 32+77). The revisions have been made as requested. 16. On plan sheet 12, please remove the "CURB RAMP ALTERNATE" because it requires a KCRS variance. The detail has been removed as requested. 17. Please make the following changes to plan sheet 13: A Modify the plan view of CB#28 to show the true locations and alignments of all pipes and other internal CB components to scale. Mr. Ted Cooper, P.E. April 13, 2006 Page 9 B. In note 2 of the "Structural Notes'; add the missing "O's" to "RIGHT-F- WAY" (two occurrences). C. In the profile of CB#28 make the fallowing changes: 1) Add a note specifying `handholds, steps or ladder see KCRS dwg. 2-006" per SWDM Fig 5.3.4.A (on page 5-40). 2) Show the shear gate rod extending all the way to the bottom of the solid locking lid (so the gate must be closed to install the lid and the shear gate rod is easily accessible). 3) Show and dimension the vertical bar grate to scale. The changes to plan sheet 13 have been made as requested. 18. Please make the following changes to plan sheet 14: A. Omit the following details that are replaced by updated details on sheet DT-02: 1) ASPHALT TRANSITION RAMP & LANDING. 2) CURB RAMP IN ROLLED CURB DETAIL The details have been removed from plan sheet 14 as requested. B. Revise%mit the "OVERFLOW SPILLWAY DETAIL" per previous comments, As discussed in the March 15, 2006 meeting and responded in the previous comments, the overflow spillway detail will remain. C. In the "NEIGHBORHOOD MAILBOX UNIT'detail, specify 1 S-boxes in each unit, per Postmaster -approved plan. The detail has been updated as requested. D. in the "NEIGHBORHOOD MAILBOX SIDEWALK MOUNTING LOCATION" detail, show and dimension the specify sidewalk easement 1'-behind the sidewalk The easement has been shown and dimensioned as requested. 19. Please make the following changes to plan sheet 15: A. Show the final grading contours for the site. The cut and fill quantities suggest that a large amount of cut material will be spread across much of the site. B. Expand the clearing limits to allow for storage of materials and final grading. C. Specify temporary drainage pipes at all locations where drainage crosses a proposed roadway. Mr. Ted Cooper, PE April 13, 2006 Page 10 D. We strongly suggest using the permanent pond and at least some of its permanent downstream system. See SWDM Section 03.5 (page D-44) "Use of Permanent Drainage Facilities': Only show those parts of the permanent drainage system that will be required for the TESL plan. Remove the overlap of temporary and permanent ponds/traps so we can tell what is proposed for TESC. E. Show downstream conveyance details for the "Tract D" sediment pond/trap. This comment was discussed extensively in the March 15, 2006 meeting. The final grading contours for the site are already shown. No temporary drainage pipes are proposed, stormwater runoff shall flow along and across the roadways using interceptor ditches that have a detail provided on plan sheet 16. Sediment Trap #2 will be constructed within the permanent pond, as suggested. The proposed drainage system is shown in order to identify the location of the catch basin sediment barriers. The following changes have been made to plan sheet 15 following the March 15, 2006 meeting: the clearing limits have been expanded to allow for storage of the cut material, the roof drain pipe system has been removed from this sheet, and minor items have been revised for clarity. 20. Please add street trees to the following locations: A. Northwest corner of Lot 27. B. Along the eastern side of "Tract D" The street trees have been added as requested. The following comment was added on March 20, 2006 to read as follows: 21. Provide a design that addresses the increase and concentration of drainage flow at the southern end of the proposed curb along 116th Avenue SE. Use one of the following options to resolve this drainage issue: A. Within the R/W, provide an infiltration swale extending south from the southern end of the proposed curb. Notice that if this swale's drainage creates a pond that extends into the neighbor's property then the second option must be used. B. Collect and convey this drainage to a drainage system (existing or proposed). Plan sheet 7 has been revised to incorporate option A The following comments were received from Kristen Langley on March 28, 2006 to read as follows: Label radii of (a) fogline striping and (b) pavement edge on NE quadrant of intersection of Road "C" at 116th Avenue SE Mr. Ted Cooper, P.E. April 13, 2006 Page 11 2. Label beginning STA of removal of fogline on 116th Avenue SE 3. If full -width overlay is required on 116th Avenue SE, label beginning and end STAB for "existing" and "new" centerline channelization 4. Label radii of curb return on SE quadrant of intersection 5. Identify unlabelled signs shown south of SE quadrant of intersection of Road "C" on 116th Avenue SE. 6. Label offsets of fogline stripe (from centerline and from edge of pavement) on NE quadrant of Road "C"I116th Avenue SE intersection 7. Add note regarding type of, and disposition (relocate, remove and transfer to KCDOT, ...) unlabelled signs in new paved area at intersection 8. Label radii of (a) fogline striping and (b) pavement edge on NW quadrant of intersection of Road 'A" at 116th Avenue SE 9. Identify unlabelled object at STA 205+00 (approx) on 120th Avenue SE 10. Provide illumination plan (per requirements of KCRS 5.05) for 116th Avenue SE The information on plan sheet 17 was revised as requested in comments #1 - #10 above.

Project Engineer CC: Joe Singh, JPS Holdings, LLC.: 1 copy of submittal set I 0 Jessie Glen Plat 1 Project No. L05P0005 (Activity No. L05SR054) Plan Review ##3 April 21, 2006 1. The following pending reviews need to be completed for engineering plan approval: A. B. DCDOT Traffic: illumination & Channelization plans. C. Significant Tree Retention Plan: Bruce Engell. 2. Please add the following items (from the previous list) to the TIR: A. Please use Figure "5.3.4H Riser Inflow Curves" (on page 5-48) to determine the 100-year water surface elevation for the 21"-diameter riser (at 9.34 cfs). Use either the nomograph or the appropriate equation below it. B. Using the results immediately above, design the pond's overflow and (secondary) emergency overflow per SWDM pages 5-19, 5-27 5-28 5-30 and 5-48. Change the following TIR calculations and pond design items on the plans• 1) overflow water surface. 2) Use 1'-thick rock for emergency overflow spillway. 3) Emergency overflow water surface. 4) Top of berm elevation (minimum 0.3' freeboard). C. Please modify the offsite 100-year undetained backwater analysis and downstream analysis so it includes the following calculations: 1) Drainage entering proposed CB#31 from the west (along SE 192nd Street). 2) For the existing CB immediately to the east of proposed CB431, show and determine the flows entering this CB from the north. Jessie Glen Plat 2 Project No. L05P0005 (Activity No. L05SR054) Plan Review #3 April 21, 2006 D. Modify the bond quantities sheets if any changes are made 3. Please make the following changes to plan sheet 3: A. Across the southern boundary of "Tract B", correct the existing note which says "30' RIGHT OF WAY". It should read as follows: "38'-ROAD "A" R/W WIDTH". B. Show and dimension the "Tract B" walkway as shown on the landscape/recreation space plans. This curvy walkway must be centered in its public access easement. C. Label and dimension the proposed "10'-UTILITY & DRAINAGE EASEMENTS" along all plat roadways north of errR T 4. Please make the following changes to plan sheets 4 and 5: A. Provide a plan view enlargement and a cross section for the Road "A" improvements adjacent to "Tract B", as follows: 1) Include the following details in the enlargement: a) Make the northern and southern boundaries of the concrete curb ramp to Tract "B" perpendicular to Road "A". b) Add dimensions/stationing for all proposed roadway paving and sidewalk along the Tract "B" frontage. c) Beginning and ending stations, with offsets, for all proposed fogline striping. 2) Provide a detailed and dimensioned roadway section that extends through the curb ramps on both sides of the roadway here. There should be a smooth Jessie Glen Plat 3 Project No. L0SP0005 (Activity No. L05SR054) Plan Review #3 April 21, 2006 transition between the "Tract B" curb ramp and this widened section of the half -street. B. Show and specify that both pairs of bollards at the ends of the Tract "B" walkway shall be placed 10'-back of the edge of the traveled way (as required by KCRS 5.11) with 50" O.C.--spacing. 5. Please revise plan sheets 10, 13, and 14 per changes required in item 2 (near the beginning of this list). 6. Please make the following changes to plan sheet 13: A. In the profile of CB#28 make the following changes: 1) Add a note specifying "handholds, steps or ladder see KCRS dwg. 2-006" per SWDM Fig 5.3.4.A (on page 5-40) . 2) Show the shear gate rod extending all the way to the bottom of the solid locking lid (so the gate must be closed to install the lid and the shear gate rod is easily accessible). 3) Show and dimension the vertical bar grate to scale. 7. Please make the following changes to plan sheet 15: A. Design the temporary drainage path flow and clearing limits so drainage doesn't flow through stored materials (Expand the clearing limits?). B. Provide an outlet for the sediment trap so it will remove sediments as designed. Drainage can't exit immediately next to its inflow stream because sediments won't settle out in such a short flow path. Jessie Glen Plat 4 Project No. L05P0005 (Activity No. L05SR054) Plan Review #3 April 21, 2006 8. Please submit plan sheets 18, 19 and 20 so they can be reviewed. The following are some of the items that could not be reviewed: A. Please add street trees to the following locations: 1) Northwest corner of Lot 27. 2) Along the eastern side of "Tract D".

Please contact Trisha Bull (DDES Planner) at 206-296-6758 because she says she can't start reviewing the recreation space plan until the review fee and other design details are submitted. 2. Please provide design details now for the luminaire required (by KCRS 5.05) at the intersection of proposed Road "D" and 116th Ave SE. KCDOT Traffic needs to review and approve it before engineering plan approval. 3. The following reviews are pending: A. Channelization plan: KCDOT Traffic. B. Significant Tree Retention Plan: Bruce Engell. 4. Please make the following changes to the TIR: A. Please provide the following information in the downstream analysis: 1) In a plan view map of the existing downstream system, show and uniquely label each pipe, drainage structure, ditch and swale. 2) Specify the lengths, diameters and slopes of all pipes. 3) Specify the lengths, critical cross sections and slopes of every ditch and Swale 4) Revise the existing drainage map and table describing it to show and describe B. The current backwater analysis and downstream analysis lack sufficient details to determine whether or not the tailwater elevation at proposed CB#31 is reasonable. We need to know whether or not this tailwater will have Jessie Glen Plat 2 Project No. L05P0005 (Activity No. L05SR054) Plan Review #2 March 13, 2006 unacceptable adverse affects on the pond's storage or the existing upstream/downstream drainage system along SE 192nd Street. Please modify the offsite 100-year undetained backwater analysis and downstream analysis so it includes the following; 1) A basin map and calculations for the following: a) Drainage entering proposed CB#31 from the west (along SE 192nd Street) . b) For the existing CB immediately to the east of proposed CB#31, show and determine the flows entering this CB from the north. 2) For the drainage system within two CB's east and west of CB#31 (along the northern side of SE 192"6 Street) map and specify the pipe sizes, pipe invert elevations, pipe lengths, pipe materials and CB rim elevations. C. Design the pond's overflow and (secondary) emergency overflow per SWDM pages 5-19, 5-27, 5-28, 5-30 and 5- 48. Address the following in these designs: 1) Clarify where the 100-year design flow rate came from. 2) Design the overflow riser pipe (in the control structure) using the riser curves (SWDM page 5- 48). Determine the overflow water surface elevation for the 100-year storm flow rate. 3) Design the size of the vertical bar grate opening for the control structure using a weir equation. Subtract the widths of the bars to get its effective width. The grate's maximum water surface Jessie Glen Plat 3 Project No. L05P0005 (Activity No. L05SR054) Plan Review #2 March 13, 2006 elevation for the 100-year storm must be less than or equal to that of the overflow riser. 4) Set the overflow elevation of the pond's (secondary) emergency overflow (or birdcage per SWDM page 5-28) at or above the riser's 100-year design water surface elevation. D. Modify the bond quantities sheets for any changes. 5. Please make the following changes to plan sheet 3 and all other affected plan sheets: A. Modify the part of the "Tract E" PAT roadway that serves 3-lots so it meets minor access roadway standards (per KCRS 2.09B). Notice the 25'-radii required at the entrance. B. Where the "Tract E" roadway serves 2-lots it can be a joint -use driveway (see KCRS 3.01C.3.a). C. Please relocate the two 16-box mailbox units on "Road A" to north of the common property line for lots 25 and 26, as approved by the U.S. Postmaster. D. Correct the sheet referenced for all mailbox details. It should be DT-04. E. Show, dimension and label all necessary drainage and utility easements for each proposed lot. Outside of the R/W, all lot drain pipes serving more than one lot must be in a drainage easement. 6. Modify all of the sidewalk ramps as follows: A. Design them per the details on sheet DT-02. B. Locate all proposed sidewalk easements 11-behind the sidewalks. Jessie Glen Plat 4 Project No. L05P0005 (Activity No. L05SR054) Plan Review #2 March 13, 2006 7. At all mailboxes, widen the proposed sidewalk easements so each is 1'-back of the sidewalk widening. 8. Provide an enlarged detail for the roadway and sidewalk improvements at the southern end of "Tract B" as follows: A. Dimension the location of the northern rolled curb so it is centered 12'-north of the "Road A" centerline. B. Across the frontage of "Tract B" maintain the proposed half -street width and connect the roadway to the ramp with a temporary 5'-wide ACP walkway. C. Locate the "Road A" northern R/W line 20'-north of the roadway centerline. This is needed to place the R/W line 1'-north of the ramp's 6'-wide sidewalk (per sheet DT-02) . 9. Please make the following changes to plan sheet 4: A. Specify that all 12"-diameter pipes must have smooth (not corrugated) linings between CB419 and CB#22 and between C9#20 and C9#21. This is necessary to meet the minimum 3-fps full -flow requirement (SWDM page 4-11). B. Make the following changes to the profile of CB#12: 1) Raise the invert of the 18"-pipe so its invert is clearly within 5'-0" of this CB's rim (as required by KCRS DWG 2-003, Note 7). Otherwise, this CB must be changed from a TYPE 1 to a TYPE 2. This is strictly enforced by our construction inspectors. 2) Add the missing 12"-pipe and its invert elevation. Jessie Glen Plat 5 Project No. L05P0005 (Activity No. L05SR054) Plan Review #2 March 13, 2005 10. On plan sheets 4 and 5, per the Postmaster's approval, show and specify the locations of all new, proposed and relocated mailboxes. Mailbox locations belong on these roadway sheets. 11. Please make the following changes to plan sheet 5: A. Please remove CB#1A from the pond tract because it isn't needed. B. At "Road A" STA 35+58 (10'LT) place a CB with its rim low enough to drain the lowest point along the northern side of this roadway. Add a plan note that says to grade the R/W along the northern side of "Road A" to drain to this CB. 12. Please make the following changes to plan sheet &: A. In the "Tract A" detail, specify the all 12"-pipes must have smooth (not corrugated) linings (to provide the 3- fps full -flow velocity required on SWDM pg 4-11). 13. Please make the following changes to plan sheet 8: A. Provide a plan view (to scale) of CB#29 showing a revised design that it is physically large enough to accommodate both inlet pipes and the steps. A 48"- diameter CB isn't large enough to accommodate the angle between the two inlet pipes. On KCRS DWG NO. 2-005, in Note 5, notice the required knockout sizes and the required spacing between them. Either a larger CB or an increased angle between these pipes is needed. B. For all existing pipes that will connect to CS #31 provide the pipe data (i.e., materials, diameters, invert elevations, slopes). Also, please verify that Jessie Glen Plat 6 Project No. LOSP0005 (Activity No. L05SR054) Plan Review #2 March 13, 2006 the pipe show with a 20"-diameter actually has this non-standard diameter. 14. Please make the following changes to plan sheet 10: A. Correct the labeling of both CB#28 and CB429 and the sheets referenced for their details. B. Install the pond gravity drain pipe, as required by SWDM item 7 on pages 6-75 and 6-100. It is possible to drain the pond with a gravity drain by only lowering the inverts of all pipe inverts at CB#29 and CB#30. The pipe run between C9#29 and C9#31 would need to have roughly a 0.5% slope (see minimum allowable pipe slope requirements on SWDM page 4-11). This gravity drain pipe could be connected directly to proposed CB#29. Its control valve should be located within the pond tract. C. We recommend replacing the pond's overflow emergency spillway with a "birdcage" structure that is located immediately downstream of the control structure. It would also have to be as close as possible to the access road. This would have the following benefits: 1) It may eliminate the need to upsize CB#29 just to physically accommodate its inlet pipes. 2) The control valve for the gravity drain pipe could be located inside this structure. 3) It should eliminate the possibility of R/W ponding and erosion from drainage flowing over the emergency overflow. 4) It would be more compatible with future R/W improvements and more aesthetically pleasing.

Provide illumination plan (per requirements of KCRS 5.05) for 116th Avenue SE GUIDELINES FOR DEVELOPER PROJECTS: CHANNELIZATION PLANS Channelization is the separation or regulation of conflicting traffic movements into definite paths of travel by islands or pavement markings to facilitate the orderly movements of both vehicles and pedestrians. Proper channelization increase capacity, , provides maximum convenience, and instills driver confidence. — A Policy on Geometric Design of Highway and Streets, AASHTO, 2001. Channelization devices include painted or plastic lines, raised pavement market, and traffic islands. In addition to standard items such as roadway centerlines and edge lines, channelization includes crosswalks, .stop lines, and turn arrows. In projects involving roadway construction or improvement, channelization should be addressed early in the design process. Items such as lane widths, taper lengths, and radii affect the required width of pavement. Determining the channelization requirements early in the process can avoid costly redesign of roadside features such as sidewalks and drainage improvements. For this reason, it is recommended that the channelization review be the first step in the Road and Drainage review process. Channelization Review Process Unlike most development plans, channelization plans are not reviewed by DDES. As authorized under Title 14 of the King County Code, King County DOT is the agency responsible for reviewing and approving all channelization plans. The Traffic Systems Unit reviews and signs channelization plans. As with other plan sets, channelization platys should be submitted to your DDES project manager. DDES then forwards the plans to the King County DOT Traffic Engineering Section for review. The plans are reviewed for compliance with the King County Road Standards (KCRS) and generally accepted engineering practice. Plan submittals are reviewed by the Traffic Systems unit, and redlines returned to DDES and the applicant. Multiple reviews of plans sets are frequently required and should be anticipated. The quality of the plan submittal and complexity of the project has a major impact on the number of reviews required. Meetings are scheduled as necessary to resolve any issues identified during the review process. Once the plans are approved, the final plans are submitted on mylars for signature by King County DOT. A Road Variance approved by the County Road Engineer is required for all roadway designs that deviate from the KCRS. It is recommended that applicants obtain all related variances prior to submitting channelization plans to avoid delays. See DDES Customer Service Bulletin number 34A for more information on the variance process. Developer Channelization Plan Guidelines Page .I Standards and Guidelines Standards and guidelines used when reviewing channelization plans, listed in the order of precedence, include: • King County Road Standards (KCRS), including Drawings 4-001 through 4-0091 • WSDOT Design Manual Chapter 910 • WSDOT Standard Plans Section H • MUTCD Part 3 Items to Include on Plan Sheets initial plan submittals should be printed on paper. Half size (I I"x 17") drawings are preferred. A scale of 1 "= 40' is required for half size drawings and 1'= 20' for full size drawings. Final plans submitted for signature shall be full size drawings printed on Myiar. It is recommended that copies of Hearing Examiner conditions and variances related to channelization be provided along with the first plan submittal. Each plan sheet shall contain a signature block with spaces for signature by the King County DOT Review Engineer and Supervising Engineer. Each plan sheet should also contain the following note: "Contractor shall notify Traffic Engineering (206-263-6110) at least 3 working days prior to striping to coordinate channelization layout and sign installation." The appearance of channelization lines on plans should be similar to the actual lines as they appear on the pavement, For example, a double yellow centerline should be shown using two 4" wide (at scale) polylines. Existing channelization should be shown throughout the project using the same line type as proposed channelization but with half- tone line weights (aka screened). Plans should show the entire roadway width with all elements listed below. Where new channelization matches with existing roadway sections, plans should show no less than 100 ft of the roadway beyond the project limits. • Survey centerline with stationing in 100' increments. • All intersecting roadways and driveways should be shown and labeled Beginning and ending stationing of project. • North Arrow and Scale Bar. • DDES Permit Number. • All roadway names along with classifications and posted speed Iimit. I These drawings are in the proposed KCRS revision, and are numbered 6-001 through 6-009 in the current KCRS. There is little substantive difference between the two drawing sets. The proposed drawings are subject to change in the adopted KCRS revision. Developer Channelization Plan Guidelines - Page 2 • Right -of -Way Lines (labeled). • Edge of pavement (labeled). • Curb, gutter and sidewalk. + Curb ramps. All pavement markings, including striping, arrows, bike symbols, stop lines, and cross walks. The type of pavement marking and beginning/ending stationing should be called out. + Beginning/ending stationing for all tapers. • Callout for removal of existing striping where necessary. • CalIout where channelization at project limits matches existing. • The following dimensions should be shown at all matchlines, intersection approaches, and where there are changes in width: - Lane widths (both sides of road, include bike lanes). - Intersection curb and/or edgeline radii. - Radii of reverse curves and other curvilinear striping. - Shy distance to roadway features (e.g. islands, vertical curb). • All signs are installed by King County DOT. Signs should be called out "to be installed by others". Sign installation details should not be included on plans. Features that are not relevant to channelization, such as topography lines, drainage, and utilities, should not be shown. Helpful Hints for Channeiization PIans Many errors can be eliminated by reviewing KCRS Drawings 4-001 through 4-009 prior to submitting plans, particularly with respect to the required striping types, pocket lengths, and tapers. It is recommended that applicants use the attached channelization checklist to review plans prior to submittal. An example plan sheet is also attached for reference. Designers should also check to ensure that intersections can accommodate the turning movements for the design vehicle using turning templates or software packages such as TM Autoturn , and should be prepared to provide documentation to support the choice of design vehicle and turning movement design upon request. Frequent errors include: • Minimum pocket and/or taper lengths not met. • Dimensions of existing channelization at project limits not shown. • Marked crosswalks provided at unsignalized intersections (crosswalks are usually provided only at signalized intersections). • Lane alignments not maintained through intersections. • Thermoplastic striping used next to bicycle lanes.

Please make the following changes to plan sheet 5: Please label Road "A" in big letters in plan view. Road "A' has been labeled as requested. In "CURB FL TABLE 9" correct the offset distance. It can't be 9.33' It must be at least the width of the southbound lane here. The curb tables have been renumbered due to the addition of a low speed curve at the intersection of Roads B and C. Curb Table #9 Mr. Ted Cooper, P.E. February 14, 2006 Page 9 has been renumbered to #7 and the radius has been revised as requested in comment #11.H. in "CURB FL TABLE 10' correct the low point CB to CB#26. As mentioned in the response above, Curb Table #10 has been renumbered to #8 and the low point CB has been corrected. Please remove the unnecessary Traffic approval block The Traffic approval block has been removed as requested. 17. Please make the following changes to plan sheet 6: lL Please label Tracts "A" and "C'; including their roadway types, in big letters in their plan views. 'B. Add the required note from Examiner's Condition 9J to the plan view of the JUD shown in the Tract "C' detail. Provide a 30' minimum lane width around the cul-de-sac island as required in KCRS DWG NO. 1-007. Revisions for parts A and B of this comment have been incorporated in plan sheet 6 as requested. For part C of this comment, the cul-de-sac island has been removed as discussed in the meeting on January 31, 2006. 18. Please make the following changes to plan sheet 7: Resolve the conflict between the proposed northern curb radius return of 116th Ave NE and the neighbor's property. There should be at least a 1'- distance between the back of the curb and the offsite property. The conflict has been resolved as discussed in comments #12.C.2) #14.A and #14.13. 8. Add a luminaire at the intersection of proposed Road "D" and 116"' Ave SE, per KCRS 5.05. Provide its design details for KCDOT Traffic to review and approve. We have notified Puget Sound Energy and they will include this item in their design. Provide drainage collection and conveyance design for drainage that will leave the proposed gutter line of 116"' Ave. SE near STA 106+40, RT. Drainage may pond immediately south of this location in an area where Mr. Ted Cooper, RE~. February 14, 2006 Page 10 where there is no established conveyance system. As discussed in the meeting on January 31, 2006, stormwater runoff for this area will flow overland towards the existing depression that runs parallel to the road, in the same direction as the road currently drains to. This information has also been mentioned in the revised Section 4 of the TIR. X( Add a plan note to contact Henry Perrin of King County DOT (206-263- 6138) before changing any pavement markings or sign locations. This note has been provided as requested. i� Please label the existing roadway, SE 89 LN (Private Road), located across from the proposed 116"' Ave. SE entrance. The existing roadway has been labeled as requested. F. Specify that existing power poles and hydrants which require relocation shall be placed behind the sidewalk This information has been added as requested. 49. Specify all sawcuts in existing pavement to be at the existing fog line (or, if necessary, within a traveled lane). in all areas where the pavement is to be widened, sawcuts should not be made within the shoulders because shoulders are not typically designed to carry the same traffic loading as traveled lanes. This information has been specified as requested. 20. Please make the following changes to plan sheets 8 & 9: A. For simplicity and clarity, please notice that plan sheets 8 and 9 probably could be combined because they duplicate many design details. Plan sheets 8 and 9 require a different scale, and as discussed in the meeting on January 31, 2006, they will not be combined. Add for the proposed abandonment and relocation of the existing driveway near the proposed intersection of Road OX 120th Ave SE. Specify that this must be coordinated with the owner of this driveway. Please see response to comment #3.E Mr. Ted Cooper, P.E. February 14, 2006 Page 7 1 L�ja Please address the following problems concerning the proposed drainage design downstream of the pond: 41}` A drainage collection/conveyance system and its details must be provided for surface flows along the western side of 120"' Ave SE, from the site to SE 192"d Street As discussed in the meeting on January 31, 2006, the ditch along the west side of 120"' Avenue SE will be restored to the original conditions and an existing drainage ditch restoration detail has been provided on plan sheet 16 to describe the approximate layout of the existing ditch shape and structure. ) Grading contours and/or ditch sections must be provided where this work is proposed. Grading contours are shown on plan sheet 15. An approximate existing ditch section is shown on plan sheet 16. Remove the "Beehive"/ "birdcage" grates from all CB's in the R/W (i.e., CB# 27, CB 430 & CB #31. We have included a dome grate detail that you may want to use for CB #31 because the leaves and other debris I observed here are likely to plug a standard grate. The plans have been revised to show and call out a dome grate for CB #27 and CB #30 that will be located in the roadside ditch on the west side of 120"' Avenue SE. (4KAdd an inlet pipe stub to CB# 27 collect upstream ditch drainage. The inlet pipe has been provided as requested. 5) Notice that the following significant benefits would result from relocating CB#29 to the Proposed utter line at about STA 203+13 a) CB #30 would not be required the pipe run from CB #29 to CB #31 would not exceed our maximum 300'-long limit b) This CB relocation would also reduce the possible ponding and erosion near the southern end of the proposed sidewalk ramp (near STA 203+24, LT). c) Decreased backwater effects on the pond. ---mod) It would be possible to install the pond's gravity drain pipe, as required by SINDM item 7 on page 6-75). r Mr. Ted Cooper, P.E. February 14, 2006 Page 12 21. The suggestion above will certainly have significant benefits to the project; therefore CB #29 has been relocated. The pond gravity drain pipe could not be installed because of the calculated in and out invert elevations of the control structure. The detention pond was designed in KCRTS with a Stage 0 Elevation of 496.25 feet and locations of the three orifices are based on this elevation. This elevation of 496.25 feet is above the pond outlet elevation of 495.25 feet, therefore a gravity drain is not possible. Per SWDM item 7 on page 6-75, "a gravity drain for maintenance shall be provided if grade allows", and as clarified above, the grade that the detention pond was designed at does now allow a gravity drain. 6) For all existing pipes that will connect to CB #32 provide the pipe data (i.e., materials, diameters, invert elevations, slopes). This information has been provided as requested. ID. Add cross sections (extending from the roadway centerline to the western P/W line of 120t" Ave SE) to describe the proposed construction at about STA 201 +80 and about STA 203+80. Per discussions in the meeting on January 31, 2006, the approximate section shown on sheet GR-02 is adequate. Please make the following changes to plan sheet 10. V Use the control structure design in SWDM Fig. 5.3.4.A (page 5-40) Notice the required solid lid (i,e., no birdcage is allowed) and vertical bar grate through its side. The control structure has been revised as requested. Notice that the following can be substituted for a rock -lined pond emergency overflow spillway. 04 "Birdcage' overflow structure, per Fig 5.3.1.0 on page 5-28. t 2) Paved asphalt overflow spillway which can also serve as an access road to the control structure (see page 5-27). We have evaluated the use of both additional options and have determined that the current rock -lined pond emergency overflow spillway is adequate. Mr. Ted Cooper, P.E. February 14, 2006 Page 13 C. install a gravity drain pipe in the pond, as required by SWDM item 7 on page 6-75). Also see page 6-100. See answer to comment #20.C.5)d). Add two perpendicular cross sections that completely describe the pond's overflow spillway dimensions and materials. The pond overflow spillway detail on plan sheet 14 has been revised and an additional cross section has been provided as requested. 22. Please make the following changes to plan sheet 11: 11A. In all roadway sections, provide at least Vof R/W behind all curbs and sidewalks (per KCRS roadway section drawings).

The Postmaster approved plan of mailboxes that are proposed or relocated (2 sheets) is attached as requested. 7. Please make the following changes to plan sheet 1: A Add the Project No. L05P0005, Activity No. L05SR054 and SWM Variance No. L05VO052 to the title block: a Fill in the answer to the `YES/NO" question asking whether or not this is an erosion sensitive area site. C. Add a plan note in bold large letters stating the following, "COORDINATE THE ROADWAY AND SIDEWALK IMPROVEMENTS WITH THOSE OF SHORT PLAT L04S0003': D. Add the plat's 5-year expiration date of 10-25-2010. The information has been added to plan sheet 1 as requested. 8. On the plans, show details of the proposed construction for short plat L04S0003. Mr. Ted Cooper, P.E. February 14, 2006 Page 4 These details (i.e., dimensions of all improvements and the R/W width) must match those proposed onsite. The following problems must be addressed acceptably to make these two projects compatible: A. Their R/W centerlines and R/W widths must match. B. The pavement widths and roadway crowns must match. C. If these two projects are not constructed at the same time, the first one will have to construct a temporary cul-de-sac. Later, when the second one is constructed, it will have to remove this cul-de-sac and finish the roadway improvements connecting the two projects. This construction sequence needs to be described on the plans. The plan sheets have been updated to show the revised roadway and R/W width of the short plat L04S0003 to match the roadway and R/W width of the proposed Jessie Glen plat. The R/W width differs only at the transition of sidewalk from one side of the road to the other. As discussed in the meeting on January 31, 2006, short plat L04S0003 shows the temporary cul-de-sac and is planned to be constructed first. A note has been added to plan sheet 1 that states to coordinate the roadway and sidewalk improvements with those of short plat L04S0003. 9. Please modify the plan approval blocks on all plan sheets except sheet 1 so there is more vertical space for DDES staff approval signatures and dates of approval. The plan approval blocks have been modified on plan sheets 2 — 20 as requested. 10. Please make the following changes to plan sheet 2: A Either fix or remove the R/W dimensioning for both major frontage roadways. The R/W dimensioning has been removed as requested. B.

February 14, 2006 Page 5 11. Please make the following changes to plan sheet 3 and all other affected plan sheets: A Connect Roads "B" and "C" with a low speed curve (per KCRS 2.10A) because they will never have a true intersection. The low speed curve has been provided as requested. B. Use a private roadway stub (per. the KCRS) behind the curb of the curve to serve lots 5 and 6. The private roadway stub has been added as requested and it will serve lots 4 through 6. This private roadway stub will reside in a new tract, Tract "E" that is designated as a joint use drive. C. Add a plan note prohibiting direct access to 116th Ave NE, per Condition la The note has been added to plan sheet 3. D. Fix the ownership inconsistency for Tract "A': In plan view it is labeled as a "PAT" (Private Access Tract). However, in the `Tract Table" it says it is listed as a public roadway owned by King County. Tract "A" will be a Private Access Tract and the "tract Table" has been revised to reflect this. E Show a proposed construction design (on this sheet and all other affected plan sheets) that will be compatible with short plat L04SO003 (currently waiting for approval). This design should include the following: 1) Show the design details of the temporary cul-de-sac proposed by L04S0003. 2) Show details of the proposed work that will be required to remove the off -site cul-de-sac and extend all of its curb, gutter and sidewalk improvements to make a standard connection to this plat. 3) Show an alternative design for the temporary on -site cul-de-sac that would be needed if the temporary cul-de-sac for L04SO003 isn't constructed in time. 4) Match the on -site R/W lines to those of L04SO003 so they are not offset Mr. Ted Cooper, P.E. February 14, 2006 Page 6 The design details of the temporary cul-de-sac proposed by short plat L04S0003 have been added to this sheet. For further information, see response to comment #8. F. Add a public access easement for the required 5'-wide public path through Tract "B" (connecting Road "A" to Road "B"). Show this pathway and its easement here and on the roadway plans. The 5 feet wide public access easement and pathway are shown as requested. G. Per Condition 9.a., from Lot 37 to the south, design Road "A" per urban subaccess street standards. Please modify the other affected sheets too. Road "A" has been revised as requested on all affected sheets. H. Per Condition 9.a., provide adequate R1W for the northern curb return where Road "A" connects to 120'h Ave SE. As discussed in the meeting on January 31, 2006 and information received in an email from Ted Cooper dated February 1, 2006, the pavement radius design has been revised to be 25 feet with an 11 foot offset at the ECR station on 120th Ave SE and a 25:1 pavement taper from the 11 foot offset (at the ECR) northward to the existing western edge of pavement along 120th Ave SE. 12. Please provide the following requested by KCDOT Traffic: A Provide channelization plans for the roadway improvements along the frontages of both 116rt' Ave SE and 120« Ave SE. Roadway striping should be as follows: 1) South of these proposed intersections, maintain the existing lane widths along both existing roadway frontages using fog line striping. This striping should not extend across proposed intersections or their radius returns. 2) Striping for the proposed northern radius return of Road "D" should extend from the end of the proposed curb to the existing edge of lane on 116t'' Ave SE 3) Striping for the proposed northern radius return of Road "A" should extend along this radius return to the existing edge of lane for 120"' Ave SE. Mr. Ted Cooper, P.F. February 14, 2006 Page 7 The channelization plan has been provided for 116"' Avenue SE and 120"' Avenue SE on plan sheet 17. B. Provide an illumination design/plan. An illumination design/plan completed by Puget Sound Energy will be provided shortly after this submittal. C. Attempt to obtain additional R/W at the north side of the proposed intersection of Road "D" with 116th Ave SE to construct the ultimate curb return design here. !f R/W can't be obtained here, provide the following: 1) A letter stating that R1W can't be obtained here. 2) Locate all roadway improvements at least 1' away from the neighboring property so they can be constructed and maintained. Per comment #14.A, where Road "D" connects to 116"' Avenue SE, the proposed northern curb return has been revised to stop within the plat With this change, the pavement edge along the northern 35 foot radius is approximately 1 foot from the R/W on the north side. Therefore, obtaining additional R/W is no longer necessary. In addition, the roadway improvements have been revised to have 1 foot spacing to the neighboring property. 13. Please show the proposed final grading contours in all plan views of roadway and drainage design plan sheets. The proposed final grading contours have been provided as requested in all plan views of roadway and drainage design plan sheets. 14. Please make the following changes to plan sheet 4: A. Where Road "D" connects to 116th Ave NE, modify the proposed northern concrete curb return so it ends within this plat The proposed northern curb return has been revised as requested. B. If R/W can be obtained, provide at least 1' of RIW width between the on - site improvements and the adjacent property. Otherwise, move the entrance to provide at least 1 ' of RIW here. With the revision made per part A of this comment, the distance between the onsite improvements and the R/W on the north side has been revised and no additional R/W will be needed. For further detail, see response to comment #12.C.2). Mr. Ted Cooper, P.E. February 14, 2006 Page 8 C.

Please add sidewalk ramps per KCRS DWG's 4-001, 4-002 and 4-003 to all plan views at the following locations: A The intersection of Road "D" and 116th Ave SE. Notice that only arterials require two ramps on each curb return. For all curb ramps, specify that transitions from rolled curbs to vertical curbs will occur within the ramps. B. The intersection of Road "A" and 120th Ave SE C. At both ends of the public access pathway through Tract "B': D. Along the south side of Road "A" immediately across from the public access pathway through Tract "B". The sidewalk ramps have been added as requested. As discussed in the January 31, 2006 meeting, a sidewalk ramp will be provided only on the south end of the public access pathway through Tract "B". Also, an additional detail sheet has been provided, plan sheet 12, which shows the curb ramp details from KCRS DWG's 4-001, 4-002, and 4-003. 16. Please make the following changes to plan sheet 5: A. Please label Road "A" in big letters in plan view. Road 'W has been labeled as requested. B. In "CURB FL TABLE 9" correct the offset distance. It can't be 9.33' It must be at least the width of the southbound lane here. The curb tables have been renumbered due to the addition of a low speed curve at the intersection of Roads B and C. Curb Table #9 Mr. Ted Cooper, P.E. February 14, 2006 Page 9 has been renumbered to #7 and the radius has been revised as requested in comment #11.H. C.

For part C of this comment, the cul-de-sac island has been removed as discussed in the meeting on January 31, 2006. 18. Please make the following changes to plan sheet 7: A. Resolve the conflict between the proposed northern curb radius return of 116th Ave NE and the neighbors property. There should be at least a 1'- distance between the back of the curb and the offsite property. The conflict has been resolved as discussed in comments #12.C.2) #14.A and #14.B. B. Add a luminaire at the intersection of proposed Road "D" and 1106 Ave SE, per KCRS 5.05. Provide its design details for KCDOT Traffic to review and approve. We have notified Puget Sound Energy and they will include this item in their design. C. Provide drainage collection and conveyance design for drainage that will leave the proposed gutter line of 116"' Ave. SE near STA 106+40, RT. Drainage may pond immediately south of this location in an area where Mr. Ted Cooper, P.E. February 14, 2006 Page i o where there is no established conveyance system. As discussed in the meeting on January 31, 2006, stormwater runoff for this area will flow overland towards the existing depression that runs parallel to the road, in the same direction as the road currently drains to. This information has also been mentioned in the revised Section 4 of the TIR. D. Add a plan note to contact Henry Perrin of King County DOT (206-263- 6138) before changing any pavement markings or sign locations. This note has been provided as requested. E. Please label the existing roadway, SE 89 LN (Private Road), located across from the proposed 116`h Ave. SE entrance. The existing roadway has been labeled as requested. F. Specify that existing power poles and hydrants which require relocation shall be placed behind the sidewalk This information has been added as requested. 19. Specify all sawcuts in existing pavement to be at the existing fog line (or, if necessary, within a traveled lane). In all areas where the pavement is to be widened, sawcuts should not be made within the shoulders because shoulders are not typically designed to carry the same traffic loading as traveled lanes. This information has been specified as requested. 20. Please make the following changes to plan sheets 8 & 9. A For simplicity and clarity, please notice that plan sheets 8 and 9 probably could be combined because they duplicate many design details. Plan sheets 8 and 9 require a different scale, and as discussed in the meeting on January 31, 2006, they will not be combined. B. Add for the proposed abandonment and relocation of the existing driveway near the proposed intersection of Road "AU 120th Ave SE Specify that this must be coordinated with the owner of this driveway. Please see response to comment #3.E. Mr. Ted Cooper, P.E. February 14, 2006 Page 11 C. Please address the following problems concerning the proposed drainage design downstream of the pond: 1) A drainage collection/conveyance system and its details must be provided for surface flows along the western side of 120'h Ave SE, from the site to SE 192"d Street As discussed in the meeting on January 31, 2006, the ditch along the west side of 1200 Avenue SE will be restored to the original conditions and an existing drainage ditch restoration detail has been provided on plan sheet 16 to describe the approximate layout of the existing ditch shape and structure. 2) Grading contours and/or ditch sections must be provided where this work is proposed. Grading contours are shown on plan sheet 15. An approximate existing ditch section is shown on plan sheet 16. 3) Remove the "Beehive"/ "birdcage" grates from all CB's in the R/W (i.e., CB# 27, CB #30 & CB #31. We have included a dome grate detail that you may want to use for CB #31 because the leaves and other debris I observed here are likely to plug a standard grate. The plans have been revised to show and call out a dome grate for CB #27 and CB #30 that will be located in the roadside ditch on the west side of 120t' Avenue SE. 4) Add an inlet pipe stub to CB# 27 collect upstream ditch drainage. The inlet pipe has been provided as requested. 5) Notice that the following significant benefits would result from relocating CB#29 to the proposed gutter line at about STA 203+13 LT : a) CB #30 would not be required the pipe run from CB #29 to CB #31 would not exceed our maximum 300' iong limit b) This CB relocation would also reduce the possible ponding and erosion near the southern end of the proposed sidewalk ramp (near STA 203+24, LT). c) Decreased backwater effects on the pond. d) It would be possible to install the pond's gravity drain pipe, as required by SWDM item 7 on page 6-75). Mr. Ted Cooper, P.E. February 14, 2006 Page 12 21 The suggestion above will certainly have significant benefits to the project; therefore CB #29 has been relocated. The pond gravity drain pipe could not be installed because of the calculated in and out invert elevations of the control structure. The detention pond was designed in KCRTS with a Stage 0 Elevation of 496.25 feet and locations of the three orifices are based on this elevation. This elevation of 496.25 feet is above the pond outlet elevation of 495.25 feet, therefore a gravity drain is not possible. Per SWDM item 7 on page 6-75, "a gravity drain for maintenance shall be provided if grade allows", and as clarified above, the grade that the detention pond was designed at does now allow a gravity drain. 6) For all existing pipes that will connect to CB #32 provide the pipe data 0 e., materials, diameters, invert elevations, slopes). This information has been provided as requested. D. Add cross sections (extending from the roadway centerline to the western R/W line of 120'h Ave SE) to describe the proposed construction at about STA 201 +80 and about STA 203+80. Per discussions in the meeting on January 31, 2006, the approximate section shown on sheet GR-02 is adequate. Please make the following changes to plan sheet 10: A Use the control structure design in SWDM Fig. 5.3.4.A (page 5-40) Notice the required solid lid (i.e., no birdcage is allowed) and vertical bar grate through its side. The control structure has been revised as requested. B. Notice that the following can be substituted for a rock -lined pond emergency overflow spillway.- 1) "Birdcage" overflow structure, per Fig 5.3.1.0 on page 5-28. 2) Paved asphalt overflow spillway which can also serve as an access road to the control structure (see page 5-27). We have evaluated the use of both additional options and have determined that the current rock -lined pond emergency overflow spillway is adequate. Mr. Ted Cooper, P.E. February 14, 2006 Page 13 C. install a gravity drain pipe in the pond, as required by SWDM item 7 on page 6-75). Also see page 6-100. See answer to comment #20.C.5)d). D. Add two perpendicular cross sections that completely describe the pond's overflow spillway dimensions and materials. The pond overflow spillway detail on plan sheet 14 has been revised and an additional cross section has been provided as requested. 22. Please make the following changes to plan sheet 11: A. in all roadway sections, provide at least 1'of R/W behind all curbs and sidewalks (per KCRS roadway section drawings). The roadway sections have been revised as requested. B. In the "!VOTES FOR TYPICAL ROADWAY SECTIONS'; remove note 7 (County Engineer pavement approval requirement). The note has been removed. C. in the notes for Tract "C'; remove note 2 (County Engineer pavement approval required). The note has been removed. D. Remove the non-standard "ROLLED CURB SECTION DRIVEWAY" details because driveway cuts are not used in rolled curb, per the KCRS. The detail has been removed. E Please make the following changes to the cross section for 116'n Ave SE 1) Provide an arterial pavement design per KCRS 4.03. The arterial pavement design has been provided as requested. 2) Show the entire roadway width, its crown and the required overlay that will cover the full width of the roadway. This information has been provided as requested. 3) Label and dimension the location of the existing roadway centerline. Mr. Ted Cooper, P.E. February 14, 2006 Page 14 This information has been provided as requested. 4) Dimension the proposed pavement widening so it specifies a 22'- wide lane adjacent to the site. This information has been provided as requested. The proposed pavement widening is 28'-wide lane adjacent to the site. 5) Please notice that there are no existing roadside ditches along either side of this roadway here. The roadside ditch along the west side of 116t' Avenue SE has been removed. There is a slight existing drainage ditch or depression along the east side of 116t' Avenue SE. F. Please make the following changes to the cross section for 120`h Ave SE: 1) Show the entire roadway width, its crown and the required overlay that will cover the full width of the roadway. This information has been provided as requested. 2) Label and dimension the location of the existing roadway centerline. This information has been provided as requested. 3) Dimension the proposed pavement widening so it specifies a 16'- wide lane adjacent to the site. This information has been provided as requested. 4) Not Used G. Please make the following changes to the cross section for "ROAD A (SUBACCESS)". 1) Begin the stationing offsite at the point where onsite and offsite improvements will connect, within Short Plat L03S0003. Curbs, gutters and sidewalks for these two properties must connect. See response for comments #8 and #11.E. 2) Use the 24'pavement width (with 12'-lane widths) required for urban subaccess roadways, in KCRS 2.03H and 2.031. Mr. Ted Cooper, RE. February 14, 2006 Page 15 The pavement width has been increased to 24 feet. 3) Correct the R/W width, dimensions and sidewalk location in note 2 so they are consistent with the other plan sheets. The information has been corrected as requested. H. Please make the following changes to the cross section for "ROAD A (SLlBACCESS 112 STREET)": 1) Correct the stationing so it is a continuation of the stationing for the full -width street. The stationing for Road "A" is continuous. 2) Modify the design to comply with KCRS 2.07B.4. The half street improvements for Road "A" will be constructed as shown on the cross-section on sheet 11 to slope at two percent towards the south curb line. This layout will assure proper drainage, bank stability, and traffic safety. L Add the following plan note to the cross sections of 116th Ave SE and 120"' Ave SE.' Plan Note. Per KCRS Section 4.01 F, a 1 inch full width overlay shall be required. If existing road section does not meet KCRS requirements, all appropriate repairs to the existing subgrade, base material, surfacing and pre -level may be required prior to placing the overlay. The overlay may be waived only upon written request and after an evaluation of pavement conditions and/or channelization requirements has been completed and approved by the County Road Engineer or Development Engineer. The plan note has been provided as requested. J. On the plans, add our attached detail for the installation of through -curb inlets in rolled curbs. The attached detail has been added as requested. 23. Please make the following changes to plan sheet 12: Plan sheet 12 has been renumbered to 13 due to adding a sheet as mentioned in comment #15 and revised to show curb ramp details. Mr. Ted Cooper, P.E. February 14, 2006 Page 16 A. Revise the control structure to comply with the SWDM requirements in Fig. 5.3.4A on page 5-40. Notice the solid locking lid and vertical bar grate. The control structure has been revised. B. Notice that CB stations and offsets can be specified to only the nearest foot The Catch Basin Curb Offset Detail shows the relationship between the flowline and the center of structure. 24. On plan sheets 12 and 15, replace all of the "King County Standard Plan Notes" with those in SWDM Reference 7.a These notes need to be up-to-date and should not be reworded, renumbered or omitted. You can add notes to the ends of each of these lists. Plan sheets 12 and 15 have been renumbered to 13 and 16 respectively and the notes have been replaced as requested. 25. Please make the following changes to plan sheet 13: Plan sheet 13 has been renumbered to 14. A. Modify all curb ramp details so they comply with the detail we have attached with this list. The curb ramp details have been updated as requested. B. Specify where you propose to use the detail labeled nCONCRETE VERTICAL CURB" because it is probably only suitable for use around the cul-de-sac island. The detail has been removed from the plan set because the cul-de- sac island has also been removed. 26. Please make the following changes to plan sheet 14: Plan sheet 14 has been renumbered to 15. A. Provide a temporary drainage collection and conveyance system that will be used before all permanent pipes, paving and CB's are installed. Show a design with details that clearly describe what is proposed (instead of a vague conceptual design). s Mr. Ted Cooper, P.E. February 14, 2006 Page 17 Interceptor ditches will provide conveyance until the CB's are installed. The plan sheet has been revised to show the interceptor ditches clearly. B. Only show those parts of the permanent drainage system that will be required for the TESC plan. For clarity, the proposed storm drainage system has been revised in this sheet to show light and in the background. Proposed sediment barrier symbols are shown to be provided once catch basins are installed. C. Since there is no defined drainage path or ditch along the 1161'' Ave SE frontage, provide a TESC design that works here. Drainage paths have been added along 116"' Avenue SE to guide runoff. D. Show additional silt fence along all clearing limits that are adjacent to this site's property boundaries. Additional silt fence has been provided as requested. E. Show inflow and downstream conveyance details for the sediment pond and the sediment trap. This information has been provided as requested. F.

The construction sequence has been provided on plan sheet 14 with the first step as requested. G. Add a plan note specifying that access must be maintained to the existing offsite driveways along 11 Wh Ave SE and 120"' Ave SE. The plan note has been added to the notes on this sheet as Note 3. H. Don't show construction entrance rock (quarry spalls) overlapping the existing offsite driveway along 120rh Ave SE. The construction entrance from 120' Avenue SE has been revised to not show rock overlapping the existing offsite driveway. Mr. Ted Cooper, P.E. February 14, 2006 Page I a 27. On plan sheets 14 and 15, remove the note (and detail) requiring ditch restoration to original conditions along 120'h Ave SE. This note and detail don't match either the existing conditions or the necessary proposed work here. Along the 120th Ave SE frontage a new ditch design (with a 3:1 maximum slope adjacent to the roadway) will be required. Plan sheets 14 and 15 have been renumbered to plan sheets 15 and 16 respectively. As discussed in the meeting on January 31, 2006, the ditch along the west side of 120t' Avenue SE will be restored to the original conditions and the note and ditch detail are only approximate representations of the shape and structure of the ditch. 28. Please put the street trees and their details on the engineering plan sheets instead of the landscaping sheets. Street trees are part of the engineering review and bonding. The street trees have been designed by a landscaped architect and the plan sheets showing street trees needs to be stamped and signed by the same landscape architect Therefore, the street trees will remain on the landscaping sheets and be submitted for engineering review together with the engineering plan sheets.

NOTE: KCC 27A authorizes right of way and site restoration bonds to be combined when both are required. The restoration requirement shall include the total oost for all TESC as a minimum, not a maximum. In addition, corrective work, both on- and off -site needs to be included. Quantities shall reflect worse case scenarios not just minimum requirements. For example, if a salmonid stream may be damaged, some estimated costs for restoration needs to be reflected in this amount. The 30% contingency and mobilization costs are computed in this quantity, NOTE: Per KCC 27A, total bond amounts remaining after reduction shall not be less than 30% of the original amount (T) or as revised by major design changes.
