We have applied for a tenant improvement permit and have been approved and it is ready to be picked up as of June 25'', 2011. Part of this minor tenant improvement project will require the use of the following steel storage containers on-site to store existing store produ_ctlshelving units while other areas of the store will be remodeled. Remodel project includes constructing a new consultation room adjacent to the pharmacy and relocating the waiting room to the sales floor area. Additionally, we will be relocating steel shelving and replacing some of the flooring. While replacing the floor, all product and shelving units will need to be removed and stored elsewhere. Thus, we will be proposing the following steel storage containers for this use: • (3) 8'x8'x40' steel storage containers located in the parking lot • (I) 8'x8'x30' steel dumpster located in the parking lot for refuse All units will be stored on-site in the parking lot for an approximate duration of2 weeks. The construction period start and completion period could range and may start as early as July 15" and may end as late as October 30"', 2011. Each storage container will have a double access door, 4' wide leafs, total 8' wide on one end of the unit. End of Project Narrative CONSTRUCTION MITIGATION DESCRIPTION: Proposed Construction Start Dates: Start date could be as early as July l 5'h and end dates could be as late as October 30'', 2011. Duration of construction project will be approximately 2 weeks within the above window. Hours of Operation: Primary hours ofoperation will be 7am to 10pm and work will be within the existing building.

The proposed project will consist of the creation of 14 single- family residential lots. The property is also known as Lot 4 of Bill Ruth Addition and is· located near SE I 83'd Street and 1121h Ave. SE .. All necessary utilities and ·stcirmwater facilities will be constructed to serve the development. This report is being prepared pursuant to the 1998 King County Surface Water Design Manual (SWDM). On-Site Drainage Analysis This project site is situated within the Panther Creek sub-basinofthe Black River Drainage sub-basin of the Green River basin. Presently, the site contains an existing residence near the center of the site. The remainder of the site is undeveloped and is covered with pasture grass and a sparse scattering of shrubs and trees native to the Pacific Northwest. The ground slopes from the northeast comer of the site to a low point at the southwest comer of the site. There is a half-acre offsite tributary area to the site. Runoff from the site flows to the southwest to be intercepted by the existing drainage system along the eastern side of 112•h Avenue S.E: The soils on the site are·Alderwood Gravelly Sandy Loam (AgB) as classified by the US Soil Conservation Service: · Upstream Drainage Analysis This site is located within the Panther Lake sub-basin·ofthe BlackR.iver bi-ainagC~ubc · basin of the Green River basin. There is a one half-acre area which drains onto the site from the east. Downstream Drainage System Description As discussed above, the flow from the site discharges to the eastern side of 1121h Avenue S.E. where it is collected by the existing drainage system and routed through the "Ruddells" detention pond at the northwest comer of SE 184th Place and 112th Ave. South. From there the flow is piped on to the "Maple Glen Regional Pond" to the northwest at the southeast comer of SE 182"d Street and 108th Ave. SE. Future Site Conditions An appropriately sized conveyance system will be designed and constructed to collect the developed on-site runoff from the proposed project: Given the proposed layout of the project, flows from the site will be collected and conveyed to the water quality and water quality facilities for discharge to 112th Avenue S.E.. The stormwater facilities will be constructed pursuant to King County Standards for level 3 ·detention in order to insure that the downstream drainage problems are not aggravated. The detention pond will be .. constructed at the west end of the site. 0 I I " 11 AV I "l 1181H AV~ -·· """ I '"' Pl S(j > I I -1321<) I I I ~ ' I !) 147111 uarn " S[ 1'811! i ,. .. :~ ..,..

The sul:!div\sion of Larson Parke proposes to extend the dead ended 114th Avenue SE an.additional 300 feet and add a cul- de-sac bulb. Also, a private road in a tract is proposed that will have inadequate stopping sight distance where the road's vertical crest curve intersects 1141h Avenue SE. . . You have sufficiently explained the site constraints in designing a conforming vertical curve. In. addition, you have agreed to provide access to the private street by means of a driveway curb drop that will control (reduce)· actual vehicular speed at the location where the stopping sight distance is diminished. The cul-de-sac length at 878 feet is over the KCRS 600-foot standard, however, there appears to be adequate provisions, via plat conditions, made to permit completion as a through road in the future. I approve this variance for cul-de-sac length on I 14th Avenue SE/SE 183rd Court. I will not require an on-site or off-site reconstruction to provide a mid-point turnaround. · . . . ·--~ ' ' I conditionally approve the variance for the reduction in stopping sight distance·on the private road serving 3 lots. The requirement shall be that the private road connect to 114'" Avenue SE across either (a) a rolled curb/gutter and.sidewalk section, or, (b) a driveway curb drop (K.CRS.Dwg. 3-004/ 005) - rather than by a radius return configuration indicated on the plat map submitted with your application. . .

Proposed Tract B will serve three lots and is required by Section 2.09.B of the KCRS to meet minor access street standards. The actual tract will be dedicated to King County for stormwater facility access.and also be encumbered with. private access ea~ements for the lot access. 2. The proposed 40-foot long vertical curve (on Tract B) at the intersection with I 14th Avenue SE has 71 feet of stopping sight distance and not the requisite 125 feet. 125 feet of sight distance would require a 152-foot vertical curve and the tract length is only 129 feet. 3. The sharp vertical curve design is necessary to meet the 15% road grade·. To improve the crest sight distance by providing fill at the far end of Tract B (and raising the road) would result in access problems for the lots adjacent to the tract. Lowering I l 4'h A venue SE to improve tlie crest sight distance is impractical as access problems to an existing driveway would.result. 4. The stopping sight distance entering the tract road is adequate; the sight distance is impaired in tlie opposite direction. Less stopping sight distance is required travelling toward the intersection · · because cars would all but stop at the intersection. · ' · ' 5. The cul-de-sac is 618 feet in length measured from the rciad intersection with SE 1851h Place. There is a high probability that I 14th Avenue SE will be.extended to the north with future development to meet with the existing southerly road stub some 330 feet away. Stafrs Findings and Conclusions: . I. 2. 3. Topographical site constrainis-(15% road grade on short private tract road) make the design of a stopping sight distance (SSD) conforming vertical curve a near impossibility. The private road in Tract B will only serve three lots and provide access to a County stormwater detention facility. The SSD entering the tract (over the crest and down the grade) is approximately 71 feet if measu~ed six feet back from the road (114'h Avenue SE) centerline. In the opposite direction, the SSD driving up the tract road is roughly 77 feet. Both SSD (entering and leaving the tract) are short of the requisite 125 feet. 71 feet of stopping distance roughly corresponds with a 14-mph vehicular speed. If the approach to the Tract B road is constructed as a.rlrivcway curb drop, vehicles would be forced to all but stop at the intersection, and the reduced sight distance should be adequate. The design of the tract road as a T intersection will also dimin.ish speeds for traffic turning into the private road. The driveway approach design would have· the added benefit of reducing the amount of traffic on the tract road as only the lot owners.and visitins would utilize the access. · @ I I I I I I I I I I I I I I I I I I I Variance File January 8, 2001 Page2 4. The proposed cul-de-sac is 878 feet long as measured from the intersection with SE 1861 h Street. 5.. Given the likely probability that 114th Avenue SE will be extended in the future, this part of the variance should be approved. The applicant is being required by DDES to provide proper!):' rights for the future road extension to the north.

You are.requesting approval for an adjustment from the 1998 King County Surface Water Design Manual (KCSWDM) Core Requirement No. I, Section 1.2.1, Discharge at the Natural Location. Our review of the information and a site visit provides the following findings: . ' . ' .. , .. L The proposed L~son Parke subdivision is loc.ited at ll41h A~enue.SE and SE.183'd Court. The 14 lot, 2.1 acre, proposed Larson Parke subdivisfoi'.i is 'filed· under Land Use Services Division (LUSD) file number L99P0003. · 2. The Larson Parke subdivision is located in the Panther Creek subbasin of the Black River basin. The parcel is subject to the Level One flow control and Basic water quality requirements of the 1998 KCSWDM. 3. The rectangular shaped lot, with its longest length in an east/west direction, sheet flows from east to west. In its present state with a single residence, sheet flow leaves the site at the southwest property comer, travels west and enters a catch basin on the east side of 112 1 h Avenue South. The flow then travels west under 1121h · Avenue South and enters Ruddell's Pond. From Ruddell's Pond, flow travels via piped conveyance northwest through the Maple Glen subdivision until reaching the · Maple Glen Regional Pond. At most, a half-acre of upstream flow enters the site from the east. · 4. The downstream drainage path has had historical flooding and conveyance problems. In 1998. Capital Improvement Project (CIP) #OA1595was constructed to increase the volume ofRuddell's and Maple Glen Regional Ponds by 25% and 300%, respectively. No drainage complaints have been recorded since the ponds ® / I I I I I I I I I I I I I I I I I I I ~ -~ -r"\ '; ; .. J \ ' Larson Parke September 28, 1999 Page 2 of3 and pipes have been upsized. Despite the recent improvements to the d~~tream conveyance and retention ponds to reduce the downstream conveyance restriction, a Phase II CIP has been defined to upgrade part of the conveyance system upstream of Ruddell's Pond. It is believed that the Phase II project will complete the . improvements needed to fully remedy the.flooding problem in the local vicinity. 5. The proposal is to collect most runoff from the project site and direct it to a single detention and water quality facility located in the southwest comer of the site. The allowed release would then be diverted from its natural discharge location and utilize a drainage easemeqt that travels west from tli.e northwest comer of the site to · l.12'h Avenue SE and then south to the catch basin that allows flows to enter · Ruddell's Pond.· Flows realign to their natural discharge path when they enter this catch basin. Nuisance flows to the parcels west of the site would be eliminated. ' :,, ~ '1 . ' 6. The applicant's engineer has already explored an altemate route suggested by the · DDES adjustment committee for released flows to bypass·Ruddell's Pond ·and enter ·the drainage system on SE 183rd Court. The applicant's engineer believes that.this alternative route also has conveyance· restrictions that would require an even ·greater amount of improvements to correct. If the applicant's suggestion of crossing under 1121h Avenue SE is utilized, then the existing pipe capacity would be evaluated for the additional I OO~year, developed, _undetained ·flows. 7. Despite the recent pond and conveyance upgrades through ·cIP #OAI 595, there remains concern for the capacity of the downstream system beyond the Meadow Glen Regional pond. Because of these concerns, the applicant is offering to increase the flow control standard used for the site from Level One to Level Two.· However, this suggestion assumes the completion of the Phase II CIP to rid the local vicinity of its flooding problem. Because of the potential timing problem between plat development and Phase II CIP improvements, other options exist The applicant could provide Level Three Flow Control on-site and ignore downstream problems. The applicant could also provide some or all of the improvements defined by the Phase II CIP. The applicant could also contribute to the. Phase II CIP. 8. No decorative ponds or shallow wells would be affected by the proposed diversion. 9. A consolidation of facilities for the proposed subdivision will be more economical in long tenn maintenance. · · Based on these findings, we hereby approve this adjustment· to allow the diversion of released flows around the downstream lots through piped conveyance with the following conditions: I. The release rates for the detention facility will be based on the land naturally draining from the site in all directions. The allowed release rate will be reduced by \ ,~,,, / ® I 11 I I I I :1 ' ' :I I I I I I 1 • I I I I I I I ,/'tarson Parke September 28, 1999 Page 3 of3 . :..: · any undetained flows that would bypass the proposed subdivision drainage.·. facilities. 2.

The purpose of the significant trees special district overlay is to provide a means to designate areas losing their natural vegetation that characterizes their community and receiving the accompanying impacts from increased stormwater runoff and decreased wildlife habitat. This district overlay limits removal of significant trees in these urbanizing areas to reduce visual impacts of development and maintain a portion of the natural vegetation and soils characteristic of the Pacific 'Northwest. B. The following development standards shall be applied to all residential, commercial (including golf courses), industrial or institutional development proposals located within a significant tree district overlay: 1.

The property is kn~wn as Lot 4 of Bill Ruth Addition. The site is located to the north of the Recorded Plat of Emerald Glen. Emerald Glen has provided a stub road to the site at the northern extension of 1141h Ave. South. The Larson property consists of approximately 2.06 acres per the assessor's map. There is an existing residence within the central portion of the site that will be retained. The remainder of the site is presently undeveloped and is mostly covered with pasture grass and a sparse scattering of shrubs and trees native to the northwest. The existing ground slopes from the northeast comer of the site to the low point at the southwest corner of the site. There is an area of approximately 0.50 acres, identified during our site visit that contributes to the flows through the site. (This area was not identified in a previous study by R. W. Beck, which is on file with King County). The field survey of the. existing condition for the site is included in this report as Exhibit A. In the existing condition surface stormwater runoff, generally flows to the southwest to be intercepted by the existing drainage system along the eastern side of 1121h Ave. SE. The site is within the Panther Creek sub-basin of the Black River Drainage sub-basin of the Green River basin. At the present time, it is proposed to develop the site into 14 lots. The structures are to be a combination of Townhouses and single family detached structures. The Larson property is within a sub-basin drainage area that is within the basin boundary of a Study prepared by R.W. Beck (on file with King County) that resulted in a King County C.I.P. The C.I.P. # is OA1595. The C.I.P. was constructed during the summer/fall of 1998. A copy of a map, taken from the R. W. Beck study, is included in this report as Exhibit B. This exhibit shows the project site in relation to the study basin. The lowest portion of the basin is approximately 2000 feet from the site. The site is approximately 1.3% of the basin. The point I-mile from the site is also shown in Exhibit B. A copy of the Thomas Brothers-pages 656 & 686-vicinity.map is included in this section. The site is within page 686 Section EI.

King County Basin Reconnaissance Summary Reports The site is within the Panther Creek sub-basin of the Black River Drainage Basin. King County has recently completed a C.I.P. that consisted of a reconstruction of the "D- 90914 Rudells" detention facility and the "Maple Glen Regional Pond. As a result, the King County Basin Reconnaissance Reports were not used in this report. 2. Flood plain/ floodway (FEMA) Maps The site is not within a 100-yr floodplain. 3. Sensitive Areas Folio Copies of the Streams, Wetlands, and Erosion Hazard portions of the Sensitive areas Folio (pages 5) showing the location of the site are included within this section. There are no King County mapped sensitive areas within or immediately adjacent to the site. 4. Drainage Investigation Information A chronological printout of historic drainage complaints made to the County within the area on grids DI & El of page 686, and B7, C7 and D7 of page 656 of the Thomas Guide is provided· in Appendix I. This covers an area beyond I mile downstream from the project site. This. information was obtained from King County DNR Drainage Investigations. The contact person was Dave Hancock@ 296-8230. Also included is a copy of the King County GIS ·color printout for the site that shows the properties.(outlined·in orange) where there have been drainage·complaints in the past. Mt. Hancock was contacted by telephone concerning the drainage complaints within the downs~ream area ofthe proposed Larson site: Mr: ·Hancock stated thalthere is a 15-year · history.of drainage problems within the downstream portion of the Larson property. King County W.A.L.R.D. has recently conducted extensive studies.within the area, which resulted in the reconstruction of the "Rudells" and "Maple Glen" detention facilities. Drainage complaints in the area were made prior to completion of the reconstruction of the Ruddell's and Maple Glen detention facilities. I I I I I I I I I I I I I •• I I I I I 5. King County Soils Survey Maps A copy of a portion of Sheet 11 of the King County Soils Survey Map is included. The site is underlain with Alderwood (AgB) soils. 6. Wetlands Inventory Maps The wetlands page of the folio does not show a King County Inventoried wetland within the site. 7. Review ofD.D.E.S. File for Toth Estates ( Recorded Plat of Emerald Glen) The D.D.E.S. file for "Toth Estates" was reviewed as a part of this report Toth Estates is located directly to the south of the Larson site and is a part of the same drainage basin. Toth Estates has been recorded as Emerald Glen. Currently houses are being constructed. Toth Estates is provided with a sophisticated infiltration system that infiltrates stormwater into a series of 36" diameter dry-wells that have been drilled to a depth of approximately 30', The current infiltration design for Toth Estate is a reconstruction of the original infiltration facility that failed shortly after construction. The Level II Downstream analysis for Toth Estates has been obtained and reviewed. However, since the construction of Toth Estates, King County has conducted additional studies within the basin that resulted in the reconstruction of the "Rudell" and Maple Glen" detention facilities. As a result, the Toth Estates Level Tl has become obsolete. The information within the Toth Estates file that may be relevant to the Larson project is the_ realization that any project that contributes stormwater runoff to the "Rudell" pond and beyond has the potential of adding to the historic fl~oding problems within the downstream system. The SEPA declaration for the Toth Estates project was appealed by the downstream property owners. 8. Conversations with W.AL.RD. Staff concerning CLP. within the Downstream System -. . ' During the initial field investigation for this report, it became obvious that since Ki11g C,ounty· had recently reconstructed two Detention Facilities, the best information is to be found at W.AL.RD. The Key Players are as follows: a. John Abdalkhani: _ Mr:Abdalkhani.was the Design Engineer for the CLP. #OA1595. Mr.Abdalkhani _ currently works for the wastewater section and can be contacted at (206) 263-4447. Mr. · · Abdalkhani was contacted in an effort to locate the CLP, file for. the basin. When Mr.Abdalkhani left W.AL.R.D., the files for the project remained in his old office. In a telephone conversation with Mr.Abdalkhani, the following information was obtained: (j) I I I I I I I I I I I I .-" I I I I I I I. 11. lll. R.W. Beck prepared a study for the entire basin that contributes runoff to the "Maple Glen Regional Pond". The study contains good information concerning the definition of the Basin and Sub-basins. The Larson Site is within the study definition area. Volume I and II of the R.W. Beck study is on file with King County. Mr. Abdalkhani estimates that after the completion of the C.I.P., the lower portion of the basin will continue to experience flooding during storin events greater than the 10-yr storm. We believe this estimate to be very conservative. If this assessment were true, more flooding should have been experienced in the area. Mr. Abdalkhani analyzed the basin independently using the hydraulic models "Extran" and "KCRTS". The same basin areas used in the R. W. Beck study was used by .Mr. Abdalkhani in his analysis. This report is on file with King County. We have reviewed the report prepared by Mr. Abdalkhani. The report contains generation of the Time Series for the different basins. b. Mike Tseng: Mr. Tseng was the Project Manager for the "Maple Glen/Ruddells" C.I.P. Mr. Tseng can be contacted at (206) 296-8319. Mr. Tseng is currently the contact person for all inquiries concerning the C.I.P. anc! has committed to making the project files available for review. Mr. Tseng has indicated that any future development within the basin needs to consider the reconstruction of the "Ruddells" and "Maple Glen" facilities. c. Fred Bennett: Mr. Bennett is with the construction services, and was involved in the reconstruction of the Ruddell's and Maple Glen facilities. Mr. Bennett assisted us in locating the files left by Mr. Abdalkhani. We visited his office in an effort to.locate additional information as tii"how the ponds were resized and how.the new conveyan'ce facilities were designed. We did not locate any other report except fo_r the one previously mentioned. Mr. Bennett said that he had spoken to Mr. Abdalkhani abouf tlie porids .. From our discussion, we · · understand that the capacity of the two ponds. were maximized as much as possible. Mr Berinett stated that the Ruddell's pond was increased by about 25 percent, while the Maple Glen pond is approximately 3 times it's former size. Mr. Bennett mentioned that the worst flooding occured on the lot across the street from the Ruddell's pond, however,· this lot has been filled and a new house has been built recently, he did not believe this new house will be flooded.
