Changes to the civil plans prepared by Bruce McVeigh, dated 12.12.2004 and received 04.17.2006, and changes to the TIR and the analysis prepared by Bruce McVeigh and dated April 10, 2006 as follows: a) Provide the soil classification system used to classify the soils on page 2 of 3 of the plans. If this is the USDA system per the KCSWDM, then please explain the classification "sandy silty loam" or reclassify per the USDA. b) Remove the infiltration detail on page 2 of 3 of the plans, since the soils shown on page 2 of 3 do not meet KCSWDM criteria for infiltration. c) Reconcile the discrepancy between the soils shown on page 2 of 3 of the plans and the TIR, referring to "soils suitable for infiltration" (page 1) and "porous surface soils" (page 2). d) Page 1 of the TIR mentions a "Basin Sketch" but none was provided. Please provide this. e) The total area of the tributary area is computed with a width of 95'. The width of the property is 130'. A detailed basin sketch should cleanup this discrepancy. f) The pervious lawn area was modeled as outwash soils. Given that the lawn areas are made up of several smaller areas on soils that do not perk, this impervious area should be modeled as till soils. g) A computation of the areas of the existing ground cover was not provided. This is needed to verify the redeveloped flow rates. h) Please include all printouts from the KCRTS program, including the pre and post development Runoff Time Series. i) Use 8" minimum conveyance pipe size. This short plat approval decision is appealable to the Hearing Examiner. In order to appeal the decision, a written notice of appeal must be filed with the Department of Community Development within 21 days of the issuance of the Notice of Decision (June 13 , 2006). The requirements for such appeals are set forth in Tukwila Municipal Code Chapter 18.116.

Recording The signature of the Chairman of the Short Subdivision Committee certifies that your short plat application is ready for recording. It is your responsibility to record the City approved short plat documents with the King County Department of Records. You will need to pay the recording fees and submit your approved original short plat to King County. The short plat is not complete until the recording occurs and copies of the recorded documents are provided to the Department of Community Development. After recording, the County returns the recorded original to the City of Tukwila within 4 -6 weeks, at which time your short plat is considered complete. You can shorten this processing time by hand - delivering a copy of the recorded short plat to the project planner. In many circumstances, building permits on the short platted property may not be issued until a copy of the recorded short plat (or original) is returned to the Department of Community Development.

As has been noted the short plat expired on June 13, 2007. The preliminary approval letter listed specific conditions that must be met prior to final approval. One condition is the installation of common improvements. In order to install those improvements, a separate public works permit was required. The City issued that permit on August 29, 2006. No work has occurred on the site and thus because the short plat has expired and due to inactivity on the site the PW permit has expired as well. On August 24, 2007 you visited with Carol Lumb regarding this same project. You provided Ms. Lumb with the same document that you provide me, except you provided the following note, "We came back to see Ms. Carol Lumb on Friday, August 24, 2007 at 1:00 P.M. We have started construction on site ". No permits have been issued and thus no work can occur. Additionally, I drove by the site and could clearly see from view of S. 148 Street that no work has occurred on site nor is there any construction equipment on the property or on the right of way. While it is unfortunate that the partners of this project are in dispute, there is no remedy that the City can offer to extend the short plat permit. This short plat has been in the process since 2004 and no progress has been made to complete the project. If you wish to continue on this project you are required to submit a new short plat application. Once the short plat is approved you will be required to obtain a public works permit in order to install the common infrastructure. As part of the short plat application the City requires an owner's affidavit. The affidavit must be signed by all individuals who are listed as owners on the title.

Design Conveyance System Analysis and Design Special Reports and Studies Other Permits ESC Analysis and Design Bond Quantities and Declarations of Covenant Operations Manual RECEIVED APR 17 2006 uu,muriUNITY DEVELOPMENT Project Overview: The proposed project will create a total of four single family residential building lots. A new 20 foot wide paved common driveway to serve an existing residence and the three future residences will be constructed . along the west side of the property to allow access. A 20. foot wide turnaround will be provided between the two middle tots. The existing lot is approximately 129 feet wide east -west and approximately 311 feet north - south, with an area of 0.92 acres. The site is located on the south side of S. 148th Street in the 4200 block in Tukwila, Washington. The existing residence and associated lawn area is located at the north central end of the parcel, and is to remain. The existing site is level across the frontage east -west, with a relatively uniform down slope to the south of typically about 5 percent, with some areas up to 12 percent. Localized grading around the existing house allows driveway access to a lower carport. The area south and downhill from the lawn around the existing house is meadow. The storm drainage system will collect flows from the roofs and driveways of the new residences as well as the common driveway and some incidental on -site lawn areas. Also entering the system will be runoff from a small area of the south side of S. 148th Street. The surface soils on the site are of a type generally suitable for infiltration, 1 however high wet seasonal groundwater levels prevent infiltration from being a feasible option for this site. All flows from new impervious areas will be collected, led through a 100 LF engineered bio- swale, detained in a subsurface detention pipe, and released downstream through a FROP mounted in a 54 inch Type 2 catch basin. Detention will be Level 2. Released flows will pass through a supplemental pipe and catch basin system south through the adjoining new short plat and thence to the street system in S. 150th Street. Conditions and Requirements Summery: The detention system is sized for Level 2 control per guidelines in the 1997 KCSWM Manual. The soils in the area experience high seasonal groundwater preventing use of on -site infiltration. Runoff from the new impervious areas will be water quality treated using a 100 LF engineered bio- swale, detained, and control released to the piped system downstream from the site. Sizing for detention will be by KCRTS methodology and will be constructed per the large site construction standards given in Manual. Post development water quality will employ a formal bio- swale, per above. Off -Site Analysis: At present practically no observable surface runoff from the site flows beyond its borders due to the surface vegetation and porous surface soils. The proposed drainage system model this condition with the use of Level 2 detention, which is relatively conservative. Based on site topography, no off -site runoff enters the site, except for a small portion of the south side of S. 148th Street which will be intercepted by the new system. A Level 1 Downstream Analysis was done of the flows released from the site. The one- quarter mile below the site consists first of a continuation of the private pipe and catch basin system south through the newly constructed infrastructure of the adjacent short plat. The flows from the subject site will be conveyed separately from the adjacent short plats drainage. The distance in this portion is about 300 feet. The flows then enter the relatively recently installed in- street system on the north side of S. 150th Street. They then travel east in this system for a distance of about 400 feet, pass under the street to the south, and then continue generally south, passing through a pipe and catch basin system supporting an elementary school. The south limits of the school system are at the approximate one- quarter mile distance, and constitute the limit of this review. All portions of the flow path indicated adequate capacity and no areas with maintenance 2 problems were noted. The proposed flows should have no identifiable adverse effect on the downstream system portions observed. Flow Control and Water Quality Facility Analysis and Design: As referenced above, the flows from the impervious surfaces will be detained on -site and released using Level 2 flow release levels. The bio-swale, placed upstream of the detention system, is designed per usual criteria. Drainage standards are per the 1997 KCSWM Manual. The method of analysis is KCRTS. Calculations are attached. Conveyance System Analysis and Design: The 6 inch and 8 inch PVC lines connect the common driveway catch basins and the remaining portions of the on -site system. The perimeter downspout collectors for the new residences will be 4 inch PVC placed at a minimum 1 percent. By inspection, the provided /specified pipe systems will be adequate for estimated post - development flows. Special Reports and Studies: None. Other Permits: The installation of the common driveway, bio -swale and the detention system will be built or bonded prior to the approval of the short plat. A permit will be required. Simultaneously, the driveway installation and some utility connections in S. 148th Street will require a separate right-of-way permit. The design and installation of drainage lines associated with the individual new residences will be incidental to the residential permits. ESC Analysis and Design: As noted above, the site is small and warrants only the normal placement of standard filter fence along the downhill limit of clearing and a rock construction entrance. These measures are temporary and for use during construction only. Bond Quantities and Declaration of Covenant: 3 City of Tukwila standard fee calculation forms are provided. Construction to take place as part of future residential construction is excluded. Easements and associated covenants are provided as part of the information on the short plat drawing. Operations and Maintenance Manual: A facility operation/maintenance manual is provided, attached to this report. Bruce . MacVeigh, P.E.

RECEDED APR 17 2006 COi.iiviUNITY Operation and Maintenance Manual for Stormwata rr"ma T Collection and Detention System Lai /CheunglChiu 4 -Lot Residential Short Plat 4245 S. 148th Street, Tukwila, WA Table of Contents: Operations of System Inspection Checklist April 11, 2006 Prepared by Bruce S. MacVeigh, P.E. Civil Engineer/Small Site Geotechnical 14245 59 Ave. S. Tukwila, WA 98168 Office: (206) 242 -7665 Fax: Same Operation and Maintenance of Short Plat Storm System The operation of both the common and individual lot portions of the system is generally simple and requires only occasional inspections and maintenance procedures. An important periodic inspection is of the large catch basin with the restrictor tee device. This will need inspection on regularly basis along with the other catch basins, and on the same schedule as noted in the checklists. Attached within this manual is the set of checklists with scheduling and maintenance requirements for all portions of the drainage system. The system consists of several catch basins in the long on -site driveway which serves the rear lots. The drainage line from these catch basins is connected to a surface bio-swale across the rear lot, which serves to clean the oils and other pollutants from the runoff water. The flows then enter a large underground storage pipe, which is followed by a large catch basin with the flow restrictor tee. The restricted flows then flow south through a storm line in the short plat located just south of the site. When the flows leave this site and enter the one to the south, the operation and maintenance of the south line is also the responsibility of this short plat, and permission is granted to inspect and maintain it as needed. The responsibility ends as this site's flows enter the street system in S. 150th Street. It is the joint responsibility of all of the homeowners to inspect, clean and maintain this system. This is done by removing the collected silt and debris from all of the catch basins at least once per year, and mowing the bottom and sides of the bio-swale. As mentioned above, the large catch basin with the restrictor tee will need to be checked on a periodic basis along with the smaller catch basins. The handling of this joint responsibility is spelled out in the storm drainage easement recorded with the original short plat. Questions about inspection and maintenance of this facility may be directed to Bruce S. MacVeigh, P.E., Civil Engineer, (206) 242 -7665. laionm /0465 INSTRUCTIONS FOR USE OF MAINTENANCE CHECKLISTS The following pages contain maintenance needs for most of the components that are part of your drainage system, as well as for some components that you may not have. Ignore the requirements that do not apply to your system. You should plan to complete a checklist for all system components on the following schedule: 1. Monthly from November through April 2. Once in late 'summer (preferable September) 3. After any major storm (use 1 -inch in 24 hours as a guideline), items marked "S" only. Using photocopies of these pages, check off the problems you looked for each time you did an inspection. Add comments on problems found and actions taken. Keep these "checked" sheets in your files. Some items do not need to be looked at every time an inspection is done. Use the suggested frequency at the left of each item as a guideline for your inspection. REQUIRED ACTIONS: The following actions shall be taken to ensure that pollution generated on site shall be minimized: 1. Warning signs (e.g., 'Dump No Waste - Drains to Stream ") shall be painted or embossed on or adjacent to all storm drain inlets. They shall be repainted as needed. Contact the Municipality regarding availability of stenciling supplies. 2. Parking lots shall be swept when necessary to remove debris and, at a minimum, twice a year. Use of newer model high - velocity vacuum sweepers is recommended as they are more effective in removing the more harmful smaller particles from paved surfaces. 3. Sediment removed from detention vaults shall be disposed of in a proper manner. Contact the Municipality for instruction prior to completing this task. 4. No activities shall be conducted on site that are likely to result in short-term high - concentration discharge of pollution to the stormwater system. Such activities may include, but not be limited to, vehicle washing, vehicle maintenance, and cleaning of equipment used in the periodic maintenance of buildings and paved surfaces. 5. Employees shall receive basic instruction regarding the control of pollution from commercial operations. Contact the Department of Ecology for assistance in completing this task.

Direct Step Backwater Method The Direct Step backwater method can be used to compute backwater profiles on prismatic channel reaches (i.e., reaches having uniform cross section and slope) where a backwater condition or restriction to normal flow is known to exist. The method can be applied to a series of prismatic channel reaches in secession beginning at the downstream end of the channel and computing the profile upstream. 9/1/98 1998 Surface Water Design M( 4 -60 • • c) The conveyance requirements in Core Requirement #4 (see Section 1.2.4) must be met. 6.3.1.2 DESIGN CRITERIA An effective biofiltration swale achieves uniform sheet flow over and through a densely vegetated area for a period of several minutes. Figure 6.3.1.A (p. 6-49) shows a typical biofiltration swale schematic. Basic design requirements for achieving proper flow conditions through a biofiltration swale are described below. Swale Geometry 1. Swale bottom width shall be betw 16 feet. a) Minimum bottom width • to allow for ease of mowing. b) If the bottom width exceeds 10 feet, a length -wise divider shall be provided. The divider shall extend from the flow spreader at the inlet for at least three - quarters of the swale length. c) Maximum bottom width is 16 feet, excluding the width of the divider. Note: Multiple swales may be placed side by side provided the flow to each swale is split at the inlet and spread separately for each swale. Adjacent swales may be separated with a vertical wall, but a low berm is preferred for easier maintenance and better landscape integration. 2. The longitudinal slope (along the directio of flow) shall be between 1 percent and 6 percent. a) If the longitudinal slope is less th • rcent, underdrains must be provided (see next page and Figure 6.3.1.C, p. 6-50, for un • er • ain s . ifications). 1998 Surface Water Design Manual b) If the longitudinal slope is less than presented in Section 6.3.2 (p. 6- c) If the longitudinal slope exc shall be provided to ieve a bo 6-41 6.3.1 BASIC BIOFILTRATION SWALES — DESIGN CRITERIA rcent, the swale must be designed according to the criteria for wet biofiltration swales. , check dams with vertical drops of 12 inches or less slope of 6 percent or less between the drop sections. 3. The swale shall be flat in cross section (perpendicular to the flow direction) to promote even flow across the whole width of the swale. 4. The minimum swale length shall b 100 > " t; no maximum length is set. 5. The swale treatment area (below the WQ design water depth) shall be trapezoidal in cross - section. if trapezoidal, side sl s . :: • ' It the treatment area should be 3H:1 V or flatter whenever possible, but not steeper 6. Side slope sectio ove the treatment area • y be steeper than 3H:1 V, subject to the following provisions: a) If there is an interior, side slope betw n 111:1V and 2H: IV outside the treatment area, the slope shall be reinforced with erosion . ntrol netting or matting during construction. b) Any interior slope steeper th 1H:1 V shall be constructed as a rockery or structural retaining wall" to prevent the swat= lope from sloughing. To ensure that adequate sunlight reaches the swale bottom, only on all can be taller than 2 feet. If possible, the higher wall should be on the northern or easte • side of the swale to,maximize the amount of light reaching the swale bottom. ' 16 Experience with blofiltration swales shows that when the width exceeds about 10 feet it is difficult to keep the water from \.1 forming low -flow channels. It is also difficult to construct the bottom level and without sloping to one side. Biofilters are best constructed by leveling the bottom after excavating, and after the soil is amended. A single -width pass with a front -end loader produces a better result than a multiple -width pass. 17 Soil bioengineering techniques may be used as an alternative to a rockery or structural retaining wall. 9/1/98 SECTION 6.3 BIOFILTRATION FACILITY DESIGNS 9/1/98 Water Depth and Base Flow 1. A swale that will be frequentl • , r. . mmercial or landscaped areas, shall have a design water depth of no more th t) under the water quality design flow conditions. 2. A swale that will not be frequently mowed, such as along roadsides or in rural areas, shall have a design water depth of no more than 4 inches (0.33 feet) under the water quality design flow conditions. 3. If a swale is located downstream of a deten n pond providing Level 2 or Level 3 flow control, and it is located in till soils (according to KCRTS soil group in Chapter 3), then the swale must be designed as a wet biofiltration swale Section 6.3.2, p. 6 -52). 4. If a swale will receive base flows b ause of seeps and springs on site, then either a low - flow drain shall be provided or a wet biofiltration swale shall be used. Low flow drains are narrow surface drains filled with pea gravel that run lengthwise through the swale to bleed off base flows; they should not be confused with underdrains. In general, base flows less than 0.01 cfs per acre can be handled with a low -flow drain. If flows are likely to be in excess of this level, a wet biofiltration swale should be used. 5. If a low - flow drain is used, it shall extend the entire length of the swale. The drain shall be a minimum of 6 inches deep, and its width shall be no greater than 5 percent of the calculated swale bottom width; the width of the drain shall be in addition to the required bottom width. If an anchored plate or concrete sump is used for flow spreading at the swale inlet, the plate or sump wall shall have a v -notch (maximum top width = 5% of swale width) or holes to allow preferential exit of low flows into the drain. See Figure 6.3.1.D (p. 6 -51) for low -flow drain specifications and details. Flow Velocity, Energy Dissipation, and Flow Spreading - 1. 2. 7. Curved swales are encouraged for aesthetic reasons, but curves must be gentle to prevent erosion and • " allow for vehicle access to remove sediment. Criteria for maintenance access road curves should also be applied for swale curves (see Section 5.3.1.1 for design of access roads). The m not exc Them exc 3.

We had a meeting with Ted Peterson in regards to the right to his easement & he's positive with the concept. Now, we are waiting for a copy of Peterson's engineering plan (James Jaeger) 'cause he promised me that he can give me a copy of it as soon as he gets a copy from James. That's where we are at now and I will keep you posted as we are moving forward together. Thanks again Tony Lai Yahoo! Mail Mobile Take Yahoo! Mail with you! Check email on your mobile phone. February 14, 2005 Tony Lai 616 Shattuck Ave S Renton WA 98055 RE: 4 -Lot Short Plat 4245 So. 148 St L04 -088 Dear Tony: City of Tukvvila Steven M. Mullet, Mayor Department of Community Development Steve Lancaster, Director The City Of Tukwila Public Works, Building and Fire Departments have the following comments regarding your application: GEOTECHNICAL 1. Standing water was observed in an open excavation hole during a site visit on January 10, 2005. Also, standing water was observed last summer in an excavation hole immediately south of this site. The houses east of this site have experienced problems with springs and perched water. One of the houses required extensive foundation redesign due to springs encountered when excavating for the foundation. 2. A geotechnical report that meets Bulletin B4 (enclosed) is required. A geotechnical engineer, as defined in updated TMC 16.54 and TMC 18.06, must prepare the report. The geotechnical report will be sent for peer review paid for the by applicant. Please provide $2,000 to cover the initial review with your geotechnical report. SURFACE WATER 3. This site is in Gilliam Creek Basin and therefore requires Level 2 detention. Please refer to the Public Works Development Guidelines and Design and Construction Standards Chapter 5 (enclosed). 4. This site does not meet KCSWDM infiltration requirements of outwash soils and the infiltration rate provided by the engineer is not sufficient for infiltration when there are no outwash soils. Provide a surface water plan and technical information report that meets the 1998 King County Surface Water Design Manual. 6300 Southcenter Boulevard, Suite #100 • Tukwila, Washington 98188 • Phone: 206- 431 -3670 • Fax: 206 - 431 -3665 FIRE ACCESS Sincerely, Kathryn Devlin Assistant Planner 5. As provided, the maintenance plan does not specify which parcels are responsible for maintenance, nor does it state how costs for maintenance, repair and upgrades will be distributed between property owners. Since this document affects how real estate is used, the Owner should have his/her attorney review the maintenance agreement before it is submitted to Public Works and before it is recorded with King County. 6. Increase the keystone wall height to reduce angle of departure on fire access road. Increasing wall height to just under 4' should reduce access road grade to 10 % or 11 in first 100' and then increase the next 50' of access road from 2% to 6.44 %, thus reducing angle of departure issue. 7. Maintain access road cross slope not to exceed 4 %. The hammerhead turnaround is not clearly shown on plan. 8. Lot 4 exceeds the 250' travel distance to a fire hydrant. Applicant can ask for exception or have notation on the recording documents that lot 4 shall have fire sprinklers installed. If you have any questions regarding the geotechnical reports you may contact Jill Mosqueda, in Public Works at 206 431 -2449 or at: jill @ci.tukwila.wa.us . I enjoyed our meeting last week and encourage you to call if you have any other concerns. I can be reached at 206 433 -7166 or at: kdevlin @ci.tukwila.wa.us. Jill Mosqueda Re: L04 -088 4245 S. 148t From: Jill Mosqueda To: Kathryn Devlin Date: 2/8/05 5:33PM Subject: Re: L04 -088 4245 S. 148th St Kathryn, I got a copy of your memo to Bob G., so you don't need to provide me a copy. I have read your memo and think you may have forgotten our discussions and the information I provided regarding access to this site. Here are some points for you to consider: LOWER STANDARDS FOR SEVEN LOTS 1. You should have a copy of an information memo dated Nov. 17, 2003 and addressed to Jim Morrow, Steve Lancaster, and Jack Pace. I think this memo outlines the same proposal you have in your memo. On 12.15.03 Jim Morrow approved access for seven lots from the 25' easement on the private property to the east, without requiring a full street improvement. The fire department would use the same turn around already in place, pending FD approval. SHARED ACCESS FROM PRIVATE EASEMENT 1. Please refer to Ordinance 1933, which I think you have a copy of. This ordinance vacated the 25' on the "Thayer short plat ". That 25' is now a private easement on private property. When we were discussing options, I asked Shelley Kerslake to review the ordinance, which has a stipulation that the City could take back the 25'. It is Shelley's opinion that this stipulation is unenforceable. 2. The City has no authority to grant access to new lots from a private easement. 3. In order to get access from that easement, the developer for L04 -088 would have to get three or four of the owners to grant access. I believe that Don-Leabo, a developer who was interested in this site, made preliminary overtures to one or more of the owners and reported to me that there was no interest in granting access. 4. Your suggestion under Recommendation is to contact the owners of the private easement and negotiate an agreement. Your memo doesn't state who would contact the owners and negotiate an agreement. Since it is an advantage to the new developer to minimize new impervious surface, I assume you expect, as PW expects, that the developer would take that on under your auspices. 5. If you are suggesting that Public Works negotiate access for the developer, please make that clear and I will present your suggestion to Jim. P.S. Bob has asked that I respectfully remind Planning that he does not manage development services. Jim Morrow manages development services and has the authority to make exceptions to development standards. If Bob receives a request for an exception to a development standard, he just forwards it to Jim. L. Jill Mosqueda P.E. »> Kathryn Devlin 02/08/05 03:11 PM »> I've written a memo to Bob G, Nora and Jack re: making an exception to the private access road standards. The next step (allowing PW is ameniable) is to make contact with the property /easement owners to get their buy in. Then I'll take it to the applicant... The memo was written last week after Nora and I met w /Bob.

This block has seve a1 existing short plats with residential, private dead -end access roads. The east boundary of the proposed short plat, L04 -088, abuts a 25' private access road that had initially been dedicated to the city in order to create a connection between S. 148 and S. 150 Subsequent development made this connection no longer possible and the City vacated the right -of way. (Reminder: TMC 17.20.030 C the City's goal is to have an integrated system of local streets.) Issue: Current Public Works standards and per TMC 17.20.030; A private access road cannot serve more than four lots nor be longer than 200'. Roads greater than 150' must have a turnaround built to Fire Dept standards. The same standards stipulate, "Any access road serving more than four lots must have 50 -60' of right of way, must be paved 28 -36' wide, and have full width improvements." This standard is prohibitively expensive for the small developer and leads us toward impermeable surface overkill in a Level 2 detention area. Recommendation: Grant an exception to the standard and allow the proposed new lots access from the twenty -five foot wide road. The alternative would cause an additional 20' wide private access road next to the existing 25' of pavement (fig 1) or a 20' wide access road on the west boundary (fig 2). The typical 200' long, 20' wide private access road creates approximately 5400 square feet of new impervious surface. Combining access for the proposed short plat would reduce the new impervious surface and would eliminate the potential of creating a grid of fenced in lots resulting in front yards facing back yards. The current owners of the 25' easement would have to agree. The next step would be to contact them and try to facilitate an agreement.

November 17, 2003 0042000025 4245 S. 148 Street PRE03 -022, DP03 -002, L92 -0061 Exception to TMC 17.20.030 C. Streets The typical '0' long, 20' wide private residential access with a hammerhead, as proposed in the preapplication PRE03 -022, creates approximately 5400 square feet of new impervious surface. Due to previous development, the lots created by the proposed short plat would have paved accesses on two sides of each lot. Refer to Figure 1. BACKGROUND The proposed short plat is in a "super block" block bounded by S. 148 St., S. 150 St., 42 Av. S. and 46` Av. S. This block contains existing short plats with residential, private, dead -end access roads. Several lots in this super -block have the potential for four -lot short plats. The proposed short plat abuts short plat L92 -0061 to the east and L02 -037 to the south. As part of L92 -0061, the owner dedicated 25' at the boundary with the proposed short plat. The City intended to use. this 25' plus property dedicated from abutting lots to create a connection between S. 148 St and S. 150 St. Due to subsequent development, this connection is no longer possible. In 2000, the City vacated this 25' of right -of -way and the four lots created by L92 -0061 have access on an easement over this 25'. Refer to Figure 2 for existing development and possible future development configurations. DISCUSSION The proposed short plat drains to Gilliam Creek and is in a Level 2 detention area. The vault or pond size will be significantly larger than a Level one vault or pond. The proponent's engineer is attempting to include Low Impact Development techniques to reduce impervious surface. Combining accesses for the proposed short plat with the L92 -0061 access would reduce new impervious surface and would eliminate the problem of roads on two sides of each new house. If the existing access remained at 25' of paved surface, there would be no new impervious surface.

RECOMMENDATION Grant exception to the standards and to TMC 17.20.030 C. The exception would be: 1. Twenty -five feet wide access easement for seven lots, 2. Easement paved the full 25' width for a distance necessary to serve all seven lots and a surface retention tract for the proposed short plat. Condition the exception with the following: 1. The short plat proponent: a. Negotiates a new easement and a new maintenance agreement with the four homeowners on short plat L92 -0061. The easement and the agreement must include all seven lots. b. Rescinds the existing easement and maintenance agreement on short plat L92- 0061. c. Records the new easement and maintenance agreement and the rescissions with King County Records against each of the seven parcels (L92 -0061 and proposed short plat). d. Records a maintenance agreement with King County that assigns maintenance responsibilities for the detention on the proposed short plat to the three new lots created on parcel 004200 - 0025. e. Rescinds or modifies the access/utility easement for short plat L02 - 037. The new easement would extend to the north property line and: • Replace ingress /egress easement for lots created in L02 -037, • Allow ingress /egress for parcel 004200 -0095 in the event the parcel is short platted, • Replace utility easement for lots created in L02 -037, • Provide utility easement, including storm drainage for parcel 004200- 0025 (proposed short plat PRE03 -022).

Tukwila, WA 98168 Office: (206) 242 -7665 Fax: Same D E VE E LOPM t The proposed project will create a total of four single family residential building lots. A new 20 foot wide paved common driveway to serve an existing residence and the three future residences will be constructed along the west side of the property to allow access. A 20 foot wide turnaround will be provided between the two middle lots. The existing lot is approximately 129 feet wide east -west and approximately 311 feet north - south, with an area of 0.92 acres. The site is located on the south side of S. 148th Street in the 4200 block in Tukwila, Washington. The existing residence and associated lawn area is located at the north central end of the parcel, and is to remain. The existing site is level across the frontage east -west, with a relatively uniform down slope.to the south of typically about 5 percent, with some areas up to 12 percent. Localized grading around the existing house allows driveway access to a lower carport. The area south and downhill from the lawn around the existing house is meadow. The storm drainage system will collect flows from the roofs and driveways of the new residences as well as the common driveway and some incidental on -site lawn areas. Also entering the system will be runoff from a small area of the south side of S. 148th Street. The soils below the end of the common driveway are suitable for infiltration. AU flows from vehicular areas will pass through catch basins with tees prior to entering the common infiltration trench located south of the end of the common driveway. Conditions and Requirements Summery: The infiltration trench is sized for a ten year storm event per Level 1 control guidelines in the KCSWM Manual. The soils in the area of the trench have a measured average percolation rate of 21.6 minutes per inch. Runoff from the new impervious areas will be retained and infiltrated using KCRTS methodology and construction standards given in Appendix C of the Manual. Post development water quality factors will include the 6 inch tees in all catch basins prior to water reaching the infiltration trench. Off -Site Analysis: At present practically no surface runoff from the site flows beyond its borders due to the surface vegetation and porous surface soils. The proposed drainage system will continue this condition. Based on site topography, no off -site runoff enters the site, except for a small portion of the south side of S. 148th Street which will be intercepted by the new system. Flow Control and Water Quality Facility Analysis and Design: As referenced above, the flows from the impervious surfaces will be retained and infiltrated on -site in an underground trench designed for the 10 -year post development rate. Sizing of the infiltration trench is based on actual percolation tests performed in the area of the proposed trench. Drainage standards are per Appendix C of the KCSWM Manual. The method of analysis is KCRTS. Calculations are attached. Conveyance System Analysis and Design: The 6 inch PVC line connecting the common driveway catch basins is placed at 8.4 percent minimum grade. The perimeter downspout collectors for the new residences will be 4 inch PVC placed at a minimum 1 percent. By inspection, the provided /specified pipe systems will be adequate. 2 Special Reports and Studies: None. Other Permits: The installation of the common driveway and the infiltration trench will be built or bonded prior to the approval of the short plat. A permit will be required. Simultan- eously, the driveway installation and some utility connections in S. 148th Street will require a separate right -of -way permit. The design and installation of drainage lines associated with the individual new residences will be incidental to the residential permits. ESC Analysis and Design: As noted above, the site is small and warrants only the normal placement of standard filter fence along the downhill limit of clearing and a rock construction entrance. These measures are temporary and for use during construction only. Bond Quantities, Facility Summaries and Declaration of Covenant: City of Tukwila standard bond calculation sheets are provided for both on -site and off - site improvements. Construction to take place as part of future residential construction is excluded. Operations and Maintenance Manual: A facility operation /maintenance manual is provided, attached to this report.

MacVeigh, P.E. Civil Engineer /Small Site Geotechnical 14245 59 Ave. S. Tukwila, WA 98168 Office: (206) 242 -7665 Fax: Same Operation and Maintenance of Short Plat Storm System The operation of both the common and individual lot portions of the system is simple and requires only occasional inspections and maintenance procedures. Attached within this manual is a set of checklists with scheduling and maintenance requirements. The commonly maintained storm system consists of a series of three Type 1 catch basins and a large 65 foot long by 11 foot wide by 4 foot deep infiltration trench. The system collects and infiltrates storm water from the private common driveway surface and from the individual house driveways and roof tops. It is the joint responsibility of all of the homeowners to inspect, clean and maintain this part of the system. The handling of this joint responsibility is spelled out in the storm drainage easement recorded with the original short plat. The water from the individual driveways and roof tops, as well as the common driveway, passes through sediment control tees, one of which is located in each common driveway catch basin. The inspection, cleaning and maintenance for these sumps is a common or joint responsibility. Note that each lot's house downspouts and gutters should be checked and cleaned each year, or more often. Doing this will also reduce the work in cleaning out the sediment sumps in the catch basins when the time comes. Details for the overall system's inspection and clean out, for both floating debris and sediment in the bottom of all catch basins, are given in the attached checklists, along with maintenance items which may affect the system's proper operation. Note that some things apply only to the individual lot portions of the system, some apply to the commonly maintained portion of the system, and some apply to both. Questions about inspection and maintenance of this facility may be directed to Bruce S. MacVeigh, P.E., Civil Engineer, (206) 242 -7665. INSTRUCTIONS FOR USE OF MAINTENANCE CHECKLISTS The following pages contain maintenance needs for most of the components that are part of your drainage system, as well as for some components that you may not have. Ignore the requirements that do not apply to your system. You should plan to complete a checklist for all system components on the following schedule: 1. Monthly from November through April 2. Once in late summer (preferable September) 3. After any major storm (use 1 -inch in 24 hours as a guideline), items marked "S" only. Using photocopies of these pages, check off the problems you looked for each time you did an inspection. Add comments on problems found and actions taken. Keep these "checked" sheets in your files. Some items do not need to be looked at every time an inspection is done. Use the suggested frequency at the left of each item as a guideline for your inspection. REQUIRED ACTIONS: The following actions shall be taken to ensure that pollution generated on site shall be minimized: 1. Warning signs (e.g., "Dump No Waste - Drains to Stream ") shall be painted or embossed on or adjacent to all storm drain inlets. They shall be repainted as needed. Contact the Municipality regarding availability of stenciling supplies. 2. Parking lots shall be swept when necessary to remove debris and, at a minimum, twice a year. Use of newer model high - velocity vacuum sweepers is recommended as they are more effective in removing the more harmful smaller particles from paved surfaces. 3. Sediment removed from detention vaults shall be disposed of in a proper manner. Contact the Municipality for instruction prior to completing this task. 4. No activities shall be conducted on site that are likely to result in short-term high - concentration discharge of pollution to the stormwater system. Such activities may include, but not be limited to, vehicle washing, vehicle maintenance, and cleaning of equipment used in the periodic maintenance of buildings and paved surfaces. 5. Employees shall receive basic instruction regarding the control of pollution from commercial operations. Contact the Department of Ecology - — the Stec 6)-59+- 5x588 for assistance in completing this task.

A new 20 foot wide paved common driveway to serve an existing residence and the three future residences will be constructed along the west side of the property to allow access. A 20 foot wide turnaround will be provided between the two middle lots. The existing lot is approximately 129 feet wide east -west and approximately 311 feet north - south, with an area of 0.92 acres. The site is located on the south side of S. 148th Street in the 4200 block in Tukwila, Washington. The existing residence and associated lawn area is located at the north central end of the parcel, and is to remain. The existing site is level across the frontage east -west, with a relatively uniform down slope.to the south of typically about 5 percent, with some areas up to 12 percent. Localized grading around the existing house allows driveway access to a lower carport. The area south and downhill from the lawn around the existing house is meadow. The storm drainage system will collect flows from the roofs and driveways of the new residences as well as the common driveway and some incidental on -site lawn areas. Also entering the system will be runoff from a small area of the south side of S. 148th Conditions and Requirements Summery: Street. The soils below the end of the common driveway are suitable for infiltration. All flows from vehicular areas will pass through catch basins with tees prior to entering the common' infiltration trench located south of the end of the common driveway. The infiltration trench is sized for a ten year storm event per Level 1 control guidelines in the KCSWM Manual. The soils in the area of the trench have a measured average percolation rate of 21.6 minutes per inch. Runoff from the new impervious areas will be retained and infiltrated using KCRTS methodology and construction standards given in Appendix C of the Manual. Post development water quality factors will include the 6 inch tees in all catch basins prior to water reaching the infiltration trench. Off -Site Analysis: At present practically no surface runoff from the site flows beyond its borders due to the surface vegetation and porous surface soils. The proposed drainage system will continue this condition. Based on site topography, no off -site runoff enters the site, except for a small portion of the south side of S. 148th Street which will be intercepted by the new system. Flow Control and Water Quality Facility Analysis and Design: As referenced above, the flows from the impervious surfaces will be retained and infiltrated on -site in an underground trench designed for the 10 -year post development rate. Sizing of the infiltration trench is based on actual percolation tests performed in the area of the proposed trench. Drainage standards are per Appendix C of the KCSWM Manual. The method of analysis is KCRTS. Calculations are attached. Conveyance System Analysis and Design: The 6 inch PVC line connecting the common driveway catch basins is placed at 8.4 percent minimum grade. The perimeter downspout collectors for the new residences will be 4 inch PVC placed at a minimum 1 percent. By inspection, the provided /specified pipe systems will be adequate. 2 Special Reports and Studies: None. Other Permits: The installation of the common driveway and the infiltration trench will be built or bonded prior to the approval of the short plat. A permit will be required. Simultan- eously, the driveway installation and some utility connections in S. 148th Street will require a separate right -of -way permit. The design and installation of drainage lines associated with the individual new residences will be incidental to the residential permits. ESC Analysis and Design: As noted above, the site is small and warrants only the normal placement of standard filter fence along the downhill limit of clearing and a rock construction entrance. These measures are temporary and for use during construction only. Bond Quantities, Facility Summaries and Declaration of Covenant: City of Tukwila standard bond calculation sheets are provided for both on -site and off - site improvements. Construction to take place as part of future residential construction is excluded. Operations and Maintenance Manual: A facility operation /maintenance manual is provided, attached to this report.

MacVeigh, P.E. Civil Engineer /Small Site Geotechnical 14245 59 Ave. S. Tukwila, WA 98168 Office: (206) 242 -7665 Fax: Same RECEIVED DEVELOPMENT NT Operation and Maintenance of Short Plat Storm System The operation of both the common and individual lot portions of the system is simple and requires only occasional inspections and maintenance procedures. Attached within this manual is a set of checklists with scheduling and maintenance requirements. The commonly maintained storm system consists of a series of three Type 1 catch basins and a large 65 foot long by 11 foot wide by 4 foot deep infiltration trench. The system collects and infiltrates storm water from the private common driveway surface and from the individual house driveways and roof tops. It is the joint responsibility of all of the homeowners to inspect, clean and maintain this part of the system. The handling of this joint responsibility is spelled out in the storm drainage easement recorded with the original short plat. The water from the individual driveways and roof tops, as well as the common driveway, passes through sediment control tees, one of which is located in each common driveway catch basin. The inspection, cleaning and maintenance for these sumps is a common or joint responsibility. Note that each lot's house downspouts and gutters should be checked and cleaned each year, or more often. Doing this will also reduce the work in cleaning out the sediment sumps in the catch basins when the time comes. Details for the overall system's inspection and clean out, for both floating debris and sediment in the bottom of all catch basins, are given in the attached checklists, along with maintenance items which may affect the system's proper operation. Note that some things apply only to the individual tot portions of the system, some apply to the commonly maintained portion of the system, and some apply to both. Questions about inspection and maintenance of this facility may be directed to Bruce S. MacVeigh, P.E., Civil Engineer, (206) 242 -7665. ?c, oe ` 24. INSTRUCTIONS FOR USE OF MAINTENANCE CHECKLISTS The following pages contain maintenance needs for most of the components that are part of your drainage system, as well as for some components that you may not have. Ignore the requirements that do not apply to your system. You should plan to complete a checklist for all system components on the following schedule: 1. Monthly from November through April 2. Once in late 'summer (preferable September) 3. After any major storm (use 1 -inch in 24 hours as a guideline), items marked "S" only. Using photocopies of these pages, check off the problems you looked for each time you did an inspection. Add comments on problems found and actions taken. Keep these "checked" sheets in your files. Some items do not need to be looked at every time an inspection is done. Use the suggested frequency at the left of each item as a guideline for your inspection. REQUIRED ACTIONS: The following actions shall be taken to ensure that pollution generated on site shall be minimized: 1. Warning signs (e.g., "Dump No Waste - Drains to Stream ") shall be painted or embossed on or adjacent to all storm drain inlets. They shall be repainted as needed. Contact the Municipality regarding availability of stenciling supplies. 2. Parking Tots shall be swept when necessary to remove debris and, at a minimum, twice a year. Use of newer model high - velocity vacuum sweepers is recommended as they are more effective in removing the more harmful smaller particles from paved surfaces. 3. Sediment removed from detention vaults shall be disposed of in a proper manner. Contact the Municipality for instruction prior to completing this task. 4. No activities shall be conducted on site that are likely to result in short-term high - concentration discharge of pollution to the stormwater system. Such activities may include, but not be limited to, vehicle washing, vehicle maintenance, and cleaning of equipment used in the periodic maintenance of buildings and paved surfaces. 5. Employees shall receive basic instruction regarding the control of pollution from commercial operations. Contact the Department of Ecology -or- he City of Tacoma -- -- t- (206)- 591 -5588 for assistance in completing this task.
