File Number (To be filled in by DDES) PRELIMINARY SUBDIVISION WORKSHEET RELATING TO DENSITY AND DIMENSIONS Several development regulations play a role in the creation of a subdivision within King County. Determining the allowable density, minimum density, and a lot width on a piece of property can be confusing. This worksheet will assist you in correctly applying specific portions of the code and will be used to determine if a proposed subdivision or short subdivision meets the density and dimensions provisions of the King County Zoning Code (Title 21A). This worksheet is designed to assist applicants and does not replace compliance with adopted local, state and federal laws. Pre-application conferences are required prior to submittal of a subdivision or short subdivision. These conferences help to clarify issues and answer questions. They may save you both time and money by eliminating delays resulting from requests for additional information and revisions. You may call 206-296-6600 to find out how to arrange for a pre-application conference.

NOTE: For parcels in the RA Zone, no rounding is allowed when calculating the allowable number of dwelling units. For example, if the calculation of the number of dwelling units equaled 2.75, the result would be 2 dwelling units. Rounding up to 3 is not allowed. (See K.C.C. 21 A.12.070(E).) IV. Required On-site Recreation Space (K.C.C. 21A.14.180): This section must be completed only if the proposal is a residential development if more than four dwelling units in the UR and R zones, stand-alone townhouses in the NB zone on property designated Commercial Outside of Center if more than four units, or any mixed use development if more than four units. Recreation space must be computed by multiplying the recreation space requirement per unit type by the proposed number of such dwelling units (K.C.C. 21A.14.180). Note: King County has the discretion to accept a fee in lieu of all or a portion of the required recreation space per K.C.C. 21A.14.185.

Minimum Urban Residential Density (K.C.C. 21A.12.060): The minimum density requirement applies only to the R-4 through R-48 zones. Minimum density is determined by multiplying the base density in dwelling units per acre (see Section II) by the net buildable area of the site in acres (see Section V) and then multiplying the resulting product by the minimum density percentage from the K.C.C. 21A.12.030 table. The minimum density requirements may be phased or waived by King County in certain cases. (See K.C.C. 21A.12.060.) Also, the minimum density requirement does not apply to properties zoned R-4 located within the rural town of Fall City. (See K.C.C. 21A.12.030(8)12.)

Minimum Density Adjustments for Moderate Slopes (K.C.C. 21A.12.087): ,Residential developments in the R-4, R-6 and R-8 zones may modify the minimum density factor in K.C.C. 21A.12.030 based on the weighted average slope of the net buildable area of the site (see Section V). To determine the weighted average slope, a topographic survey is required to calculate the net buildable area(s) within each of the following slope increments and then multiplying the number of square feet in each slope increment by the median slope value of each slope increment as follows: -----sq. ft 0-5% slope increment X 2.5% median slope value= + -----sq. ft 5-10% slope increment X 7.5% median slope value= sq. ft 10-15% slope increment X 12.5% median slope value= -----+ sq. ft 15-20% slope increment X 17.5% median slope value= -----+ + -----sq. ft 20-25% slope increment X 22.5% median slope value= sq. ft 25-30% slope increment X 27.5% median slope value= -----+ + -----sq. ft 30-35% slope increment X 32.5% median slope value = + -----sq. ft 35-40% slope increment X 37.5% median slope value = Total square feet -----in net buildable area + ------ + ------ + ------ + ------ + ------+ ------ + ------ ______ Total square feet adjusted for slope Calculation: total square feet adjusted for slope divided by total square feet in net buildable area ----- = -----weighted average slope of net buildable area = -----% (Note: multiply by 100 to convert to percent -round up to nearest whole percent) Use the table below to determine the minimum density factor. This density is substituted for the minimum density factor in K.C.C. 21A.12.030 table when calculating the minimum density as shown in Section VI of this worksheet. Weighted Average Slope of Net Minimum Density Factor Buildable Area(s) of Site: 0% --less than 5% 85% 5% --less than 15% 83%, less 1.5% each 1% of average slope in excess of 5% 15% --less than 40% 66%, less 2.0% for each 1 % of average slope in excess of 15% EXAMPLE CALCULATION FOR MINIMUM DENSITY ADJUSTMENTS FOR MODERATE SLOPES: + + + + + + + _____ sq. ft 0-5% slope increment X 2.5% median slope value = --'==-sq. ft 5-10% slope increment X 7.5% median slope value= 10,000 20,000 --~--sq. ft 10-15% slope increment X 12.5% median slope value= -----sq. ft 15-20% slope increment X 17.5% median slope value= -----sq. ft 20-25% slope increment X 22.5% median slope value = 750 + 2,500 + + ----- + ----- + ----- + ----- + ----- _____ sq. ft 25-30% slope increment X 27.5% median slope value= _____ sq. ft 30-35% slope increment X 32.5% median slope value= _____ sq. ft. 35-40% slope increment X 37.5 % median slope value= ---===--Total square feet 30,000 3,250 Total square feet in net buildable area adjusted for slope 3,250 Total square feet adjusted for slope divided by 30,000 Total square feet in net buildable area = .108333 Weighted average slope of net buildable area = 11 % (Note: multiply by 100 to convert to percent -round up to nearest whole percent) Using the table above, an 11 % weighted average slope of net buildable area falls within the 5% --less than 15% range which has a minimum density factor of 83%, less 1.5% for each 1 % of average slope in excess of 5%. Since 11 % is 6% above 5%, multiply 6 times 1.5 which would equal 9%. Subtract g% from 83% for an adjusted minimum density factor of 74%. This replaces the minimum density factor in K.C.C. 21A.12.030 table. 071130 cruz SubdivDensityDimensionCalcFORM lc-cal-subden.pdf 11128/2007 Page 4 of 6 VIII. Maximum Dwelling Units Allowed (K.C.C. 21A.12.030 -.040): ·This section should be completed only if the proposal includes application of residential density incentives (K.C.C. 21A.34) or transfer of density rights (K.C.C. 21A.37). Maximum density is calculated by adding the bonus or transfer units authorized to the base units calculated in Section Ill of this worksheet. The maximum density permitted through residential density incentives is 150 percent of the base density (see Section II) of the underlying zoning of the development or 200 percent of the base density for proposals with 100 percent affordable units. The maximum density permitted through transfer of density rights is 150 percent of the base density (see Section II) of the underlying zoning of the development. _____ base density in dwelling units per acre see (Section II) X 150% = maximum density -----maximum density in dwelling units per acre X site area in acres = maximum dwelling units allowed utilizing density incentives (K.C.C. 21A.34) _____ base density in dwelling units per acre (see Section 11) X 200% = maximum density _____ maximum density in dwelling units per acre X site area in acres = maximum dwelling units allowed utilizing density incentives with 100 percent affordable units (K.C.C. 21A.34) _____ base density in dwelling units per acre (see Section 11) X 150% = maximum density _____ maximum density in dwelling units per acre X site area in acres= maximum dwelling units allowed utilizing density transfers (K.C.C. 21A.37) Calculation: + + base allowable dwelling units calculated in Section 111 ------ bonus units authorized by K.C.C. 21A.34 ______ transfer units authorized by K.C.C. 21A.37 ______ total dwelling units (cannot exceed maximum calculated above) IX. Minimum Lot Area For Construction (K.C.C. 21A.12.100): Except as provided for nonconformances in K.C.C. 21A.32: A. In the UR and R zones, no construction shall be permitted on a lot that contains an area of less than 2,500 square feet or that does not comply with the applicable minimum lot width, except for townhouse developments, zero-lot-line subdivisions, or lots created prior to February 2, 1995, in a recorded subdivision or short subdivision which complied with applicable laws, and; B. In the A, F, or RA Zones: 1. Construction shall not be penmitted on a lot containing less than 5,000 square feet; and 2.

The Project Manager Program (PMP) seeks to provide customers with increased predictability for the permit process and better accountability from County review staff. For permit applications using the PMP, a project manager is assigned to the permit to facilitate communication with the applicant and provide a fee estimate to cover the anticipated scope of review. The project manager will also monitor and manage the permit application throughout the review process to ensure review schedules remain in line with performance standards and the overall work hours are within the range of estimated fees for the project. The enclosed information provides a summary of the fee estimate for the anticipated work disciplines associated with the preliminary review phase and fee estimate revisions which may affect the final permit fees. If you have any questions regarding the permit fees, please contact me via e-mail at lanny.henoch@kingcounty.gov or by telephone at 206-296-6632.

These comments are being offered in addition to other comments provided on this subject by other LUSD staff members participating in the pre-application process (see memorandum from Mark Follmer and Pat Simmons). Please note that after filing a short subdivision application, the short plat application must be deemed "complete" by LUSD before "vesting" of the application occurs, and substantive review of the application can proceed. With regard to your future submittal of a short plat application, the following required documents have either not been provided thus far, or are deficient. I. Land Use Permit Application Form: This form must be completed for each of the short plat applications and submitted. 2. Certificate of Sewer Availability: A Certificate of Sewer Availability must be sub.mitted for the proposed applications, namely two, five-lot short plat applications. The Certificate which was provided references proposed buildings, rather than short subdivision applications. The Certificate must also reference the tax parcel numbers. We reco1runend that a separate Certificate be provided for each short plat application, since the parcels in question are under different ownership, and each short plat application must be able to stand on its own. 3. Certificate of Water Availability: The above comments regarding the Certificate of Sewer Availability also apply to the Certificate of Water Availability.

The attached list provides a summary of design issues which must be addressed in order to submit a complete application The scope of these comments is my evaluation of the application documents submitted on December 18, 2007, in preparation for Step 3 of the pre-application process. These comments pertain to the road and drainage engineering aspects of the application only. Zoning, environmental, and administrative issues are not addressed. The objective of the review was primarily to determine the completeness of the application and secondarily to follow up on comments that were offered in the two previous meetings. Some issues will not be finally decided at this point due to complexity and are beyond the scope of this review. Others may be recognized during the preliminary review or the engineering review that are not recognized now. Sincerely, /tllkA~ I Mark Follmer, P.E. Engineer Attachments Application Review Notes Benson Heights Short Plat 1 -Loranger Benson Heights Short Plat 2 -Cruz Page 1 of3 Roads -2007 KCRS January 16, 2008 A07PP003 A07PP004 1. The intersection spacing between the PAT and SE l 70'h is less than the required 500 feet for a minor arterial (2.10.B). A variance is required (Section 1.12). This does not cause the application to be deemed incomplete, but the variance must be approved prior to making a decision on the short subdivision application (Section 1.12). Multiple issues may be included in the same application. See Customer Information Bulletin No. 34, which explains the road variance process. 2. The existing frontage improvements along 108'h Ave. are shown as unchanged. No cross · section is shown. Frontage improvements and roadway width will be further reviewed during the engineering review phase of the project. 3. Stopping sight distance along SE 170'h Street has not been shown. This must be determined prior to recording. 4. The private access tract does not appear to have curbs. The tract shall include curb and gutter (Section 2.09 B.3). This will be a condition of preliminary approval but does not cause the application to be deemed incomplete. Drainage -2005 KCSWDM The Level I Drainage Analysis is incomplete according to the submittal requirements described in the Drainage Manual. A full Technical Information Report (TIR) is not required for the preliminary application, only the Level I Downstream Analysis is required (2.2.1 and Table 2.1.2.A). However, since it is obvious that this project will not be a small project review, a TIR will eventually be required as a part of the full drainage review, and it will include a Level I Downstream Analysis. There may be further requests for additional information that become necessary during the screening and review process. Organize the Level I Downstream Analysis according to tasks, per 2.3, p. 2-10. Include the exhibits applicable to the Level I Downstream Analysis with the Level I (TIR Section 3). Refer to King County Surface Water Design Manual (KCSWDM) Section 2.3.1.1, p. 2-9, for the complete requirements for the Level 1 Downstream analysis. The following comments refer to the tasks of a Level I Downstream Analysis as described in the KCSWDM. Task 1. Study Area Definition and Maps 1. The map of the downstream system does not show the flow path from the site to the 108th Ave. SE conveyance system. Show the existing flowpaths on the maps and describe in the narrative and on the Offsite Analysis Drainage System Table.

The map of the downstream area should be a scale large enough to show the locations of the drainage features mentioned in the na1rntive, such as individual catch basins, culve1ts, and ditches. 3. The proposal "to reroute the offsitc upstream away from private properties and to the public drainage system at the location shown in SE 170th Street" (as stated on page 9 of 19) may not be in compliance with Core Requirement #1, Discharge at the Natural Location. a. Include an approved drainage adjustment in your next submittal for the diversion of flow or revise the design. (This does not make the application incomplete, but it would put the review on hold.) b. The flow path is not showr downstream from the CB on the north side of SE 1701h Street. Provide a downstream map for this flow path. Task 2: Resource Review I. The resources shown on page 2-11 shall be reviewed for existing potential problems upstream and one mile downstream of the project site. List each resource and document any information pertaining to the site from each resource, noting existing and predicted problems. If the resource was unavailable, not relevant, or otherwise not reviewed for this application, so state. 2. Drainage complaints have not been included (Reference: KCSWDM 2.3. l, p. 2-11). Show the drainage complaints by number on the same map as the drainage system description (2.3, Task 4, p. 2-12). Label the parcel numbers and associated complaint numbers on the map. Provide copies of any relevant drainage complaints from DNRP Water and Land Resources Division. Task 4. Drainage System Description and Problem Descriptions Each drainage system component and problem shall be addressed in the offsite analysis report in three places: on a map (Task!), in the narrative (Task 4), and in the Offsite Analysis Drainage System Table (see Reference Section 8-B). Task 5. Mitigation of Existing or Potential Problems 1. Provide a statement addressing any existing or potential offsite drainage problem and how the project would neither aggravate any existing problem nor create an additional problem. 2. Give a description of the flow control system proposed. 3. State whether the downstream includes any of the three defined problem types defined on page 1-23 of the KCSWDM.

Seven lots may be created on each parcel. • Minimum Density: The minimum density is 75% of the allowable density. Five lots may be created on each parcel. The minimum density must be met by the proposed short plat unless the applicant can demonstrate the layout of the short plat will not preclude minimum density being met by future development. The proposed 5 lot on each parcel meets the minimum density requirements. • Maximum Density: The maximum density is R-27. Maximum density (i.e., exceeding the base density) may be achieved only through the use of Residential . Density Incentives (KCC 21 A.34) or the use of Transfer of Development Rights O<CC 21A.37). lfTDR's are to be utilized to achieve maximum density, a purchase & sale agreement or TDR certificate is required. • Minimum Lot Size, Minimum Width, and Other Related Requirements: The minimum lot area is 2,500 sq. ft., unless the lots are developed with townhouses. The minimum lot width is 30 feet, unless the lots are developed with townhouses. The required front yard setback is 10 feet (20 feet for garages), and the required Page 1 of 5 U:\My Documents\Short Plat Pre-Apps\A07PP003 & 004-Step 3 Memo.doc 01/18/2008 side yard setback is 5 feet. The maximum permitted impervious surface percentage of a lot in this zone is 85%. Recreation Tracts Area of the Recreation Tract: A recreation tract must be provided in each proposed short plat which contains at least 170 square feet for each lot. At minimum 850 square feet of recreation space for each site will be required. The recreation tract must be improved and landscaped per KCC 21A.16. It is recommended that the recreation tracts be located side by side to maximize the recreation area. • Recreation Tract Design Requirements: The following design requirements must be met per KCC 21A.14.180. " The recreation tract must be centrally located with good visibility from roads and sidewalks (KCC 21A.14.180C4). The proposed tract meets this requirement. " The recreation tract must be accessible and convenient to all residents within the proposed short plat (KCC 21A.14.180C8). The proposed tract meets this requirement. " The recreation tract must have no dimension less than 30 feet, except for trail segments (KCC 21A.14.180C5). The proposed tract meets this requirement. " The recreation tract must have a grade and surface suitable for recreation improvements; have a maximum grade of 5%; and be located in an area where the topography, soils, hydrology, and other physical characteristics are of such quality as to create as to create a flat. dry. obstacle-free space in a configuration that allows for passive and active recreation. (KCC 21A.14.180C1 and C3) • Recreation Tract Improvements: Recreation play equipment and landscaping are required in the recreation tract. Please provide a proposed conceptual improvement plan with the submittal of your short plat application. A final detailed recreation plan, equipment specs, landscape planting details (per KCC 21A.16), and a bond quantity worksheet will all be required after preliminary short plat approval is granted, and prior to engineering plan approval. • Pedestrian/Equestrian Trails: A community or regional trail corridor may be required across the proposed short plat (KCC 21A.14.230), or may be proposed by the applicant (KCC 21A.14.360). Short Plat Design/Layout and Limitation: Page 2 of 5 • , • In addition to other comments noted in this memorandum, the layout of lots and tracts in the proposed short plat will need to be revised to address the following: >-> Any critical Areas (wetland/stream) and its associated buffer must be delineated in a tract and shown on the site plan. KCC 19A 12.050 requires that a maximum of nine lots inside the urban growth area may be created from two or more contiguous parcels with any common ownership interests. The proposed sites for the two short subdivisions must demonstrate separate ownership with no common interests. Boundary Line Adjustment: >-> BLA must be submitted and approved prior to the short plat preliminary approval. >-> Density calcs must be based the approved BLA. Required Building Permit SEPA The division of an existing duplex residence into two lots is proposed. Modifications to the structure may be required in order to comply with the Building Code. We recommend contacting the Building Services Division to ascertain all building modifications, if any, which will be required. If changes to the building are needed, they must be completed before the related short plat can be recorded. • This proposed short plat may be subject to review under the State Environmental Policy Act (SEPA). A short plat is subject to SEPA review if it is a "second generation" short plat (i.e., the parcel proposed for short subdivision was itself created by a short plat); or the parcel contains land covered by water and physical intrusion into the inundated land will occur with the short plat improvements; or an acre or more of land will be disturbed (including future residential improvements such as homes and driveways). A portion of the site appears to meet the critical area criteria. Please submit 21 copies of the completed SEPA Environmental Checklist when you submit your short plat application. Note that as part of the Environmental Checklist, King County requires that your checklist evaluate potential impacts to Climate Change from your proposal. You may use a worksheet DOES provides with the Environmental Checklist to meet this requirement, or provide other information and analysis to address this issue. Both the Environmental Checklist and the worksheet are available on the ODES website · (www6.metrokc.gov/ddes/scripts/formsDetail.cfm?ListForm=1 ). Page 3 of 5 Utilities • Critical Areas Designation: A Critical Areas Designation (CAD) is required to be submi_tted with your application to the Health Department for preliminary Health Department approval, if the parcel proposed for short subdivision is located in an area designated "Rural" by the King County Comprehensive Plan. DOES staff will prepare a CAD upon the submittal of a request from an applicant, the submittal of the necessary fees and special Critical Area report(s). • Certificates of Water and Sewer Availability: Certificates of Water Availability and/or Sewer Availability from the Soos Creek Water & Sewer District are provided and must be submitted with your short plat application. Schools • Impact Fee: The site is located within the Renton School District. Currently, there is no school impact fee for this District. • School Walkways: State law requires that consideration be given to the adequacy of walkways to neighborhood schools or school bus stops as part of the review of a short subdivision application (RCW 58.17 .110). Therefore, please provide an inventory map of existing walkway conditions (i.e. widths, surface type, condition of surface, etc.) of the walking routes to the elementary, junior high and high schools, or to the appropriate bus stop locations associated with each school. Note, off-site improvements to walkway routes may be required as a condition on the approval of your short plat. Street Trees • Street trees will be required and must be planted at a rate of one tree for every 40 feet of frontage along all public roads (KCRS 5.03 and K.C.C. 21 A.16.050). Spacing may be modified to accommodate sight distance requirements for driveways and intersections. Transportation Concurrency • A Certificate of Transportation Concurrency is required. This can be obtained from the King County Dept. of Transportation. To secure a Certificate go to www.kingcounty.gov/kcdot/roads/planning/concurrency/ or contact Jeff Lee at 206-263-4759. The applicant has provided a certificate of concurrency. Road Mitigation Fees {MPS fees) • King County Code 14.75, Mitigation Payment System (MPS), requires the payment of a traffic mitigation fee (MPS fee) and an administration fee for each residential lot or dwelling unit created. MPS fees are determined by the zone in which the site is located. This site is in Zone 334. MPS fee ($1,775 current fee) may either be paid at the time of final short plat recording, or deferred until Page 4 of 5 ' ' Other building permits are issued for the recorded lots. The amount of the fee will be determined by the applicable fee ordinance at the time the fee is collected. Fire Protection: The proposed short plats will be reviewed following submittal by the King County Fire Marshall. It is likely fire protection sprinkler systems will be required for A07PP003, based on the proposed design for access.

PROJECT OVERVIEW The project site (see the Appendix, Site Vicinity Map) information is as follows: PARCEL A: I 080 I SE 170th St, Renton, WA 98055 KING CO Parcel 2923059026 (R-18) The site is located in: A PORTION OF NW 1/4 OF THE SE 1/4 OF SECTION 29-23-5 KING COUNTY, WASHING TON The site is located within the urban growth area of unincorporated King County of the Duwamish- Green River Watershed and located just downgrade of the ridgeline that defines the drainage basin in the Benson Hill vicinity. The Appendix, USGS Site Location Map shows the site in relation to the ridgeline and other features. The project proposes a boundary adjustment with the adjacent property to the south resulting in a 0.311-acre property area as shown in the Appendix A Exhibit, "Area Map: Benson Heights Plat-2". The site is currently developed with an existing duplex and associated asphalt parking area and concrete drives. The remainder of the site is lawn. The existing duplex will remain and a proposed lot line will serve to divide the units into 2 individual lots (Lots A & B) for the purpose of selling each duplex side independently. A 2-unit dwelling (Lot I) and two single family dwellings (Lots 2 & 3) are proposed to the east of the existing duplex. The duplex will continue to access from SE 170 1h Street via two existing concrete driveways, while three (3) proposed driveways will provide access to Lots 1-3 from SE 170th Street. The asphalt area indicated by the hatching in the Appendix exhibit, "Area Map: Benson Heights Plat -2" will be removed and planted with grass. The site is bounded by an adjacent property (Zoned R-18) to the west and south per the proposed boundary line adjustment, SE 170th Street to the north and a single family residence (R-12) to the east. The majority of the site is flat with 3-foot slope down to a swale located along the eastern half of the south property line. Frontage improvements for SE 170th Street are required as shown in the Appendix A Exhibit, "Area Map: Benson Heights Plat-2" including new curb, gutter and sidewalk The United States Department of Agriculture defines the site soil as AgC-Alderwood gravelly sandy loam (Hydrologic Group C). A geotechnical report (see Section 6. Special Reports and Studies) prepared for the site indicates that the site soil is silty sand (SM) and not recommended for general infiltration from impervious surfaces. BENSON HEIGHTS PLAT 2-TIR 12/17/2007 PAGE 3 OF' J 9 Site design criteria are based on the Requirements of the 2005 King County Surface Water Manual (KCSWDM), as currently adopted. The project proposes a total of 6,040 sf (square feet) of on-and off-site impervious area. Per the KCSWDM Flow Chart, p. 1-11 and per feedback from Mark Follmer, PE King County Engineer it appears that the site qualifies for Small Project Drainage Review even though one of the lots (Lot I) proposes a 2-unit multi-residential structure. The project requires as Targeted Drainage Review since alteration of an existing conveyance pipe larger than 12" is required. Should the project be subject to Full Drainage Review (since one of the proposed dwellings is a 2-unit multi-residential dwelling), an analysis of the project for Full Drainage Review with respect to flow control has been provided in Appendix B and is discussed further in the "Core Requirement 3: Flow Control" Section below. 2. CONDITIONS AND REQUIREMENTS SUMMARY Conditions Summary This section is intended to meet agency specific requirements for all applicable Core and Special Requirements of the 2005 King County Surface Water Manual (KCSWDM). For purposes of applying the threshold for small project drainage review, the new impervious surface onsite coverage will be limited to 4,772 sfby a covenant, which is 56.1 % of the property and less than the maximum allowed by code (85% impervious for R-18). The project exceeds the 2,000 sf threshold which triggers at a minimum a "Small Project Drainage Review". The site qualifies as a "Targeted Drainage Review" Project per modification to an onsite pipe larger than 12". The site lies within a "Conservation Flow Control Area". Consequently, this report intends to address all site specific drainage issues. Core and Special Requirements Analysis Core Requirement 1. Discharge at the Natural Location In the pre-developed site condition the 0.311-acre site, zoned R-18 runoff currently flows overland. Lots A & B currently developed with the a duplex and associated driving surfaces drain (uncontrolled) to an onsite catch basin ( cb) located at the site northwest corner. The Appendix map, "Level I Downstream Analysis Map" shows the downstream drainage condition once the site flow enters the existing northwest corner onsite cb. Refer to the level one-offsite analysis in section ill of this report for a detailed description of the downstream. Since the remainder of the site is grassed and flat (approximately 2% slope to the south) little to no drainage offsite to the adjacent property is expected to occur. There are no indications of erosion or drainage patterns that would indicate concentrated onsite drainage to offsite property. The developed site condition with proposed drainage system is shown in the Appendix A Exhibit, "Grading & Stormwater Plan". A new inlet is proposed to drain the frontage improvements via a BENSON HE113HTB PLAT 2-TIR 12/17/2007 PAGE 4 OF 1 g proposed pipe connecting to the existing SE 170th Street conveyance system located on the north street side. Per the manual Lots 1-3 require drainage systems and utilities in compliance with the King County storm drainage code, discussed in further detail in the following report sections. New onsite impervious drainage from Lots 1-3 will be tight-lined to the SE 170th Street system, while upstream offsite drainage will be routed in a new conveyance pipe to its current discharge location at the site southeast comer. Lots A & B currently developed with a duplex and associated driving surfaces drain (uncontrolled) to an onsite catch basin located at the site northwest comer and will continue to do so in the developed condition. There are no proposed basin diversions for the project, the same area will contribute to the same basin in the pre-and post-development conditions. Core Requirement 2. Offsite Analysis A level one-offsite analysis is required and is provided in section III of the Technical Information Report (TIR). Core Requirement 3: Flow Control The intent is to meet the requirements of the "Conservation Flow Control Area" for a Small, Targeted Project Drainage Review; however the included calculations show that the project is also exempt from formal detention under the Full Drainage Review. The project proposes a total of6,040 sf(square feet) of on-and off-site impervious area. With regard to the Small Drainage Project requirement the site does not qualify for dispersion due to lack of area / length of flow-path criteria or in.filtration due to a low infiltration rate per the geotechnical report (Section 6). In order to minimize impact the project proposes the following: I) Per a stormwater covenant limit the proposed impervious to 56.1 % of the site (allowable is 85%). 2) Remove 1,323 sf onsite and 138 sf offsite existing impervious asphalt and replace with grass. 3) Provide grass-crete surface for all proposed onsite driveway areas. 4) Provide perforated pipe connections. Assuming the project was required for Full Drainage Review, the provided calculations in Appendix B show that the project is exempt from flow control based on the KCSWDM Exception#2, p. 1-35 as follows: The difference in the sum of the I 00-year peak flow is 0. 098-cfefor the post-and pre-developed site, less than the 0.1-cfe difference threshold In summary, the drainage plan provides an onsite conveyance system utilizing perforated pipe that BENSON HEIGHTS PLAT 2-TIR l 2117/2007 PAGE 5 0~ 1 9 will convey all proposed roof drainage to the proposed SE 170fu Street inlet. Grass-crete is proposed for the driveways, which will retain precipitation in its porous sub-base to be slowly infiltrated. Restoring existing impervious areas to grass and limiting new impervious areas will minimize any potential downstream impact. Core Requirement 4: Conveyance System Conveyance system elements are shown in Appendix A Exhibit, "Grading & Stormwater Plan" and capacity calculations are provided in Appendix C. Core Requirement 5: Erosion and Sedimentation Control Erosion Control Systems are recommended in Section IX of the TIR. An ESC Plan is provided in the Appendix A Exhibit, "Erosion & Sedimentation Control Map". ESC details referenced on the civil plans are also included in Section 8. Core Requirement 7: Financial Guarantees and Liability Ifrequired, Financial Guarantees and Liability issues, forms, bonds and covenants will be addressed per request. Core Requirement 8: Water Quality The project is exempt from formal Water Quality per KCSWDM Surface Area Exemption #1 (less than 5,000 sf PGIS) since the proposed on-site PGIS is only 510 sf, while the proposed off-site PGIS is nearly zero, as the proposed and existing lane width are nearly identical. Grass-crete is proposed for the driveways. The grass protected within the modules functions to treat runoff that is not fully infiltrated. Special Requirement #1: Other adopted area-specific requirements. The site is located within the urban growth area of unincorporated King County of the Duwamish- Green River Watershed and located just downgrade of the ridgeline that defines the drainage basin in the Benson Hill vicinity. The Appendix A Exhibit, "USGS Site Location Map" shows the site in relation to the ridgeline and other features. The site is known to be listed in a "Conservation Flow Control Area". Special Requirement #2: Floodplain/Flood way delineation The project is not adjacent to streams or wetlands. Hence, formal floodplain delineation is not warranted nor required. Special Requirement #3: Flood Protection Facilities The project does not contain nor is it adjacent to a Class I or 2 Stream and the project does not propose to construct or modify any flood protection facility. BENSON HEIGHTS PLAT 2-TIR 12/17/2007 PAGE 6 OF 1 9 Special Requirement #4: Source Controls The project does not require a commercial building or commercial site development permit. Therefore, this requirement does not apply to the site. Special Requirement #5: Oil Control The site is not a high-use site. Therefore, this requirement does not apply to the site. BENBCN HEIBHTS PLAT 2-TIR 12/17/2007 PAGE 7 OF" 19 3. OFF-SITE ANALYSIS (LEVEL ONE DOWNSTREAM DRAINAGE ANALYSIS) The site is located within the urban growth area of unincorporated King County of the Duwamish - Green River Watershed and located just downgrade of the ridgeline that defines the drainage basin in the Benson Hill vicinity. The Appendix A Exhibit, "USGS Site Location Map" shows the site in relation to the ridgeline and other features. The site is known to be listed in a "Conservation Flow Control Area". LD Engineering, LLC performed a field reconnaissance on April 9, 2007 to conduct field observations and report any substantive issues with regard to the downstream conditions. Our reconnaissance included inspection of the downstream pipe network for a distance in excess of Y. mile. For the assessment, refer to the Appendix A Exhibits, "Level I Downstream Analysis Map" and Table, "Off-site Analysis Drainage System Table Surface Water Design Manual, Core Requirement #2. Proposed site impervious is directed to an offsite proposed catch basin located at a low point on the south side of SE 170th Street. A proposed pipe will convey drainage to the existing conveyance system within the north side of SE 170th Street. Drainage is conveyed west for approximately 219 lf (linear feet) in a 12" pipe to the intersection of I 08th Ave SE. Drainage is then conveyed south in the east side of I 08th Ave SE for approximately 507 lf, crossing 91 If to the west side of 108th Ave SE and discharging to a channel. The channel conveys drainage west for over 752 lffeet in an area heavily overgrown with briars. Visual reconnaissance of downstream properties or the downstream system revealed no indication of scour, flooding, plugged culverts, overtopping or general drainage problems. Our conclusions are: (I) Continued maintenance of the existing public storm drains is important to prevent future flooding. (2) Meeting the storm water flow control requirement BMP's may effectively mitigate impacts from the proposed development. The following is an analysis of the upstream condition. The Appendix A Exhibit, "Upstream Area Map" delineates the 1.76-acre upstream area which contributes runoff to the ditch line along the south side of SE 170th Street. The upstream drainage area consists of roof, yard and driveway runoff from approximately four ( 4) upstream residences. The flow contributed by the upstream area is estimated to be 0.53 cfs for the 100-year storm per the calculations presented in Appendix D. Currently, this drainage collects at the existing inlet located in the northeast site corner. The drainage is then conveyed south by an existing 21" CMP pipe, discharging at the toe of slope which defines the adjacent property to the south. The runoff travels approximately 87 If at the toe of slope where it encounters a retaining wall then has no defined course and sheets over the adjacent property, collecting during the wet season in a low spot just behind the house. LD Engineering, LLC could not BENSON HEll3HTB PLAT 2-TIR 12/17/2007 PAGE 8 OF 1 9 locate any drainage easements associated with any portion of the drainage system on either of the two private properties. The condition of the 21" pipe and channel are poor. The 21" pipe has reverse slope at -0.50%, promoting standing water and consequently much accumulated sediment, which in turn creates more standing water. The three property owuers bordering the pipe-ditch system report that the standing water is a nuisance and as a breeding area for misquotes. The site reconnaissance indicates that the 18"-pipe entering the north side of the cb has no associated flow as it is an abandoned stub, most likely abandoned in the year of 1994 with development of the Heron Glen Condominium across the street on the north side of SE 170th Street. Therefore, it is suspected that the 18-and 21-inchpipes are what remain of a larger abandoned system that predates the development to the north. Since the s abandonment of the original system the newer drainage system within the north side of SE 170th Street intercepts and collects all drainage from areas north of the road which would have previously discharged to what remains of the antiquated system. The adjacent property owner to the east and long time resident, Robert Lyon confirmed that the above analysis is accurate. Even though the proposed drainage plan does not alter the discharge point, this option is not the preference of any of the adjacent property owuers. We recommend tying proposed Area Drain#! (the new collection point for the off site runoff) to proposed CB# 1 which would redirect the upstream public street drainage back to the street system rather than onto private properties. Pipe capacity calculations in Appendix D show that the proposed 12" pipe capacity is more than sufficient to pass the 25-year storm of the upstream and developed project areas. However, the drainage plan does not propose to alter to the current discharge location and only reroutes the drainage in a new pipe in order to provide adequate offset to the proposed units. Hence, should the County establish a reason not to "fix" the drainage system as recommended this development would not be consequently impacted. As a final note, the adjacent property owuer to the south intends to direct this offsite drainage through his property to the storm drainage system within I 081h Ave SE, approximately 344 If dowustream of the recommended discharge location. Allowing the drainage to be directed to CB#! would provide the most effective and efficient solution. BENSON HEll3HT9 PLAT 2-TIR 1 2/l 7/2007 PAGE 9 OF 1 C;I 4. FLOW CONTROL AND WATER QUALITY FACILITY ANALYSIS AND DESIGN Existing Site Hydrology (Part A) In the existing site hydrology of the 0.311-acre site runoff flows overland. Lots A & B currently developed with the a duplex and associated driving surfaces drain (uncontrolled) to an onsite catch basin ( cb) located at the site northwest corner. The Appendix map, "Level I Downstream Analysis Map" shows the downstream drainage condition once the site flow enters the existing northwest comer onsite cb. Refer to the level one-offsite analysis in section III of this report for a detailed description of the downstream. Since the remainder of the site is grassed and flat (approximately 2% slope to the south) little to no drainage offsite to the adjacent property is expected to occur. There are no indications of erosion or drainage patterns that would indicate concentrated onsite drainage to offsite property. Off site runoff from the south ditch line concentrates at the northeast onsite inlet and is routed in an existing 21" pipe to the toe of slope at the south property line. This runoff collects at a low spot on the adjacent property to the south. Developed Site Hydrology (Part B) The site proposes to direct all new impervious onsite areas to an onsite conveyance system utilizing perforated pipe and discharging to a proposed SE 170th Street inlet as part of the frontage improvements. Grass-crete is proposed for the driveways, which will retain precipitation in its porous sub-base to be slowly infiltrated. Restoring existing impervious areas to grass and limiting new impervious areas will minimize any potential downstream impact. The existing duplex and concrete drive surfaces will continue to drain to the existing onsite cb located at the property northwest comer. Per the geotechnical report (Section 6) the site is not suitable for general infiltration. Performance Standards (Part C) The site lies within a Conservation Flow Control Area. The applicable flow control BMP's are perforated pipe and grass-crete as discussed in Section 2. Conveyance calculations are presented in Appendix C. Formal water quality, source or oil control is not applicable. Flow Control System (Part D) No formal control is required. Refer to the Appendix A Exhibit, "Grading & Stormwater Plan" for BMP's that will mitigate runoff quantity. Water Quality System (Part E) NIA BENSON HEIGHTS PLAT 2-TIR 1 2/ 1 7/2007 PAGE 10 OF 19 5.

Any sediment that is tracked onto pavement shall be removed immediately by sweeping. The sediment collected by sweeping shall be removed or stabilized onsite. The pavement shall not be cleaned by washing down the street, except when sweeping is ineffective and there is a threat to public safety. If it is necessary to wash the streets, a small sump must be constructed. The sediment would then be washed into the sump where it can be controlled and discharged appropriately. 4. Any quarry spalls that are loosened from the pad and end up on the roadway shall be removed immediately.

Mulch also enhances plant establishment by conserving moisture, holding fertilizer, seed, and topsoil in place, and moderating soil temperatures. There is an enormous variety of mulches that may be used. Only the most common types are discussed in this section. Conditions of Use As a temporary cover measure, mulch should be used: I. On disturbed areas that require cover measures for less than 30 days 2. As a cover for seed during the wet season and during the hot summer months 3. During the wet season on slopes steeper than 3H:JV with more than 10 feet of vertical relief. ce Water Design Manual -Appendix C l/24/2005 ~ \'\, C-81 • C.3.1 TEMPORARY ESC 3. Standard strength fabric requires wire backing to increase the strength of the fence. Wire backing or closer post spacing may be required for extra strength fabric if field performance warrants a stronger fence. 4. Where the fence is installed, the slope shall be no steeper than 2H; 1 V. 5. If a typical silt fence (per Figure C.3. l .E) is used, the standard 4 x 4 trench may not be reduced as long as the bottom 8 inches of the silt fence is well buried and secured in a trench that stabilizes the fence and does not allow water to bypass or undermine the silt fence. Maintenance Standards I. Any damage shall be repaired immediately. 2. If concentrated flows are evident uphill of the fence, they must be intercepted and conveyed to a sediment trap or pond. 3. It is imponant to check the uphill side of the fence for signs of the fence clogging and acting as a barrier to flow and then causing channelization of flows parallel to the fence. If this occurs, replace the fence or remove the trapped sediment. 4. Sediment must be removed when the sediment is 6 inches high. 5. If the filter fabric (geotextile) has deteriorated due to ultraviolet breakdown, it shall be replaced. I FIGURE C.3.1.E SILT FENCE JOINTS IN FILTER FABRIC SHALL BE SPLICED AT POSTS.

Conditions of Use Vegetated strips may be used downslope of all disturbed areas. Vegetated strips are not intended to treat concentrated flows, nor are they intended to treat substantial amounts of overland flow. Design and Installation Specifications I. The vegetated strip shall consist of a 25-foot minimum width continuous strip of dense vegetation with a permeable topsoil. Grass-covered, landscaped areas are generally not adequate because the volume of sediment overwhelms the grass. Ideally, vegetated strips shall consist of undisturbed native growth with a well-developed soil that allows for infiltration of runoff. 2. The slope within the strip shall not exceed 4H: l V. 3. The uphill boundary of the vegetated strip shall be delineated with clearing limits as specified in Section C.3.1.5 (p. C-86).

Note: Thicknesses may be increased for disturbed areas in or near critical areas or other areas highly susceptible to erosion. _}> Maintenance Standards I. The thickness of the mulch cover must be maintained. 2. Any areas that experience erosion shall be re-mulched and/or protected with a net or blanket. If the erosion problem is drainage related, then the drainage problem shall be assessed and alternate· drainage such as interceptor swales may be needed to fix the problem and the eroded area re-mulched. Quality Standards Air-dried; free from undesirable seed and coarse material No growth inhibiting factors No visible water or dust during handling. Must be purchased from supplier with Solid Waste Handling Permit This mulch category includes hydraulic Application Rates 2"-3" thick: 2-3 bales per 1000 sf or 2-3 tons per acre Approx. 25-30 lbs per 1000 sf or 1000-1500 lbs per acre 2" thick min.: approx. 100 tons per acre (approx. 800 lbs per cubic yard) Apply at rates from 3,000 lbs per acre Remarks Cost-effective protection when applied with adequate thickness. Hand-application generally requires greater thickness than blown straw. Straw should be crimped to avoid wind blow. The thickness of straw may be reduced by half when used in conjunction with seeding. Shall be applied with hydromulcher. Shall not be used without seed and tackifier unless the application rate is at least doubled. Some wood fiber with very long fibers can be effective at lower application rates and without seed or tackifier. More effective control can be obtained by increasing thickness to 3'. Excellent mulch for protecting final grades until landscaping because it can be directly seeded or tilled into soil as an amendment. Sources for compost are available from the King County Commission for Marketing Recyclable Materials at (206) 296-4439. (Bonded Fiber slurries composed of to 4,000 lbs per The BFM shall not be applied immediately before, during or immediately after rainfall so that the matrix will have an opportunity to dry for 24 hours after installation. Application rates beyond 2,500 pounds may interfere with germination and are not usually recommended for turf establishment. BFM is generally a matrix where all fiber and binders are in one bag, rather than having to mix components from various manufacturers to create a matrix. BFMs can be installed via helicopter in remote areas. They are approximately $1,000 per acre cheaper to install. Matrix) wood fiber. paper fiber or a combination of the two held together by a binding system. The BFM shall be a mixture of long wood fibers and various bonding agents. Chipped Site Average size shall be Vegetation several inches. 1/24/2005 acre and based on manufacturers recommendations 2H minimum thickness C-82 This is a cost-effective way to dispose of debris from clearing and grubbing, and it eliminates the problems associated with burning. Generally, it should not be used on slopes above approx. 10% because of its tendency to be transported by runoff. It is not recommended within 200 feet of surface waters. If seeding is expected shortly after mulch, the decomposition of the chipped vegetation may tie up nutrients important to grass establishment. 2005 Surface Water Design Manual -Appendix C 9.

A minimum of 6 inches of free draining base material (sand or gravel) is required under the modular grid material. 2. The modular grid material must be installed according to the manufacturer's instructions. 3. The surface area of the modular grid openings must be at least 50% of the total surface area of the modular grid pavement. 4. The modular grid openings must be filled with gravel, sand, or a mixture of both. 5. Smooth surface walkways may be run across modular grid pavements, provided the impervious surfaced walkways do not exceed 10 percent of the total pavement surface. C.2.6.6 GRASSED MODULAR GRID PAVEMENT Grassed modular grid pavement is basically a modular grid pavement with grass planted in the openings or in a thin layer of soil over the grid material. The benefits of this measure are reduced runoff peaks and volumes resulting from the increased infiltration of stormwater, the increased water storage provided in the grid soil and base, and the increased evapotranspiration provided by the grass. The grassed surface also helps remove pollutants that are left behind by vehicles. Uses: Low-traffic or infrequently used areas such as low-traffic driveways, overflow parking, event parking, church parking, employee parking, maintenance access roads, etc.; they are not allowed in King County road right-of-way. Design Specifications l. A minimum of 6 inches of free draining base material (sand or gravel) is required under the modular grid material. 2. The modular grid material must be installed according to the manufacturer's instructions. 3. The surface area of the modular grid openings must be at least 50% of the total surface area of the modular grid pavement. 4. The modular grid openings must be filled with a sandy soil mix suitable for growing grass as specified by the manufacturer's instructions or a landscape architect. 5. Smooth surface walkways may be run across modular grid pavements, provided the impervious surfaced walkways do not exceed 1 0 percent of the total pavement area. C.2.6.7 MAINTENANCE INSTRUCTIONS FOR PERMEABLE PAVEMENT lf the permeable pavement flow control BMP is proposed for a project, the following maintenance and operation instructions, plus any provided by the manufacturer or installer, must be recorded as an attachment to the required declaration of covenanl and grant of easement per Requirement 3 of Section C.1.3.3 (p. C-18). The intent of these instructions is to explain to future property owners, the purpose of the BMP and how it must be maintained and operated. These instructions are intended to be a minimum; DDES may require additional instructions based on site-specific conditions or manufacturer's recommendations. Also, as the County gains more experience with the maintenance and operation of these BMPs, future updates to these instructions will be posted on King County's Surface Water Design Manual website. Cl TEXT OF INSTRUCTIONS FOR NON-VEGETATED PERMEABLE PAVEMENT Your property contains a stormwater management flow control BMP (best management practice) called "permeable pavement," which was installed to minimize the stormwater quantity and quality impacts of some or all of the paved sunaces on your property. Permeable pavements reduce the amount of rainfall 2005 Surface Water Design Manual -Appendix C 1/24/2005 C-63 SECTION C.2 FLOW CONTROL BMPs that becomes runoff by allowing water to seep through the pavement into a free-draining gravel or sand bed, where it can be infiltrated into the ground. The type(s) of permeable pavement used on your property is: D porous concrete, D porous asphaltic concrete, D permeable pavers, D modular grid pavement. The area covered by permeable pavement as depicted by the flow control BMP site plan and design details must be maintained as permeable pavement and may not be changed without written approval either from the King County Water and Land Resources Division or through a future development permit from King County. Permeable pavements must be inspected after one major storm each year to make sure it is working properly. Prolonged ponding or standing water on the pavement surface is a sign that the system is defective and may need to be replaced. If this occurs, contact the pavement installer or the King County Water and Land Resources Division for further instructions. A typical permeable pavement system has a life expectancy of approximately 25-years. To help extend the useful life of the system, the surface of the permeable pavement should be kept clean and free of leaves, debris, and sediment through regular sweeping or vacuum sweeping. The owner is responsible for the repair of all ruts, deformation, and/or broken paving units. Q TEXT OF INSTRUCTIONS FOR VEGETATED PERMEABLE PAVEMENT 1124/2005 Your property contains a stormwater management flow control BMP (best management practice) called 'grassed modular grid pavement,' which was installed to minimize the stormwater quantity and quality impacts of some or all of the paved surfaces on your property. Grassed modular grid pavement has the runoff characteristics of a lawn while providing the weight-bearing capacity of concrete pavement. The grassed surface not only minimizes runoff quantity, it helps to filter pollutants generating by vehicular use of the surface. The composition and area of grassed modular grid pavement as depicted by the flow control BMP site plan ~) and design details must be maintained and may not be changed without written approval either from the King County Water and Land Resources Division or through a future development permit from King County. Grassed modular grid pavement must be inspected after one major storm each year to make sure it is working properly. Prolonged ponding or standing water on the pavement surface is a sign that the system defective and may need to be replaced. If this occurs, contact the pavement installer or the King County Water and Land Resources Division for further instructions. The grassed surface of the pavement must be regularly mowed and maintained in a good condition. Bare spots must be replanted in the spring or fall. 2005 Surface Water Design Manual -Appendix C C-64 APPENDIX A BENSON HEIGHTS PLAT 2-TIR 1 2/17/2007 PAGE 15 OF° 19 Cruz/Loranger Site . t ......;__-,-i- :!l ~·· " Site Vicinity Map LD Engineering LLC Cruz/Loranger Site J • .--------,-.-7-------,:"'_":.---------:,;"',-;-1-------;,~,;.-------3;.5 klll * M .. !Gi USGS Site Location Map LD Engineering LLc 'A DATA IN SQUARE FEET (SF) FOR KCRTS MODEL INPUT PRE-DE ...

Parcels: 2923059026 & 2923059028 Cruz/Loranger Site Dear Sirs: This geotechnical report presents the results of our geotechnical soils evaluation of the above referenced project; see the Appendix, Site Vicinity Map for the project location. The 0.78-acre project area includes two parcels one with an existing duplex and the other a single family residence, see the Appendix, Site Plan. The duplex will remain, while the residence will be demolished. A total of up to 10 new dwelling units will be developed. INTRODUCTION The project site (see the Appendix, Site Vicinity Map) is located on 2 parcels at the following addresses and information: PARCEL A: 10801 SE 170th St, Renton, WA 98055 KING CO Parcel 2923059026 (R-18) PARCELB: 17014 108th AVE SE 98055 KING CO Parcel 2923059028 (R-18) The site is located in: A PORTION OF NW 1/4 OF THE SE 1/4 OF SECTION 29-23-5 KING COUNTY, WASHINGTON The site is located within the Duwamish -Green River Watershed, located just downgrade of the ridgeline that defines the drainage basin in the Benson Hill vicinity. The Appendix, USGS Site Location Map shows the site in relation to the ridgeline and other features. The 0. 78-acre project area includes two parcels with an existing duplex (Parcel A) and single family residence (Parcel B), refer to the Appendix, Site Plan. The duplex will remain, while the residence will be demolished. A total ofup to 10 new dwelling units will be developed. Four new units are proposed for Parcel A with driveway access directly off SE 1701h Street. The six units proposed for Parcel B will have driveway access off a proposed interior drive accessing I 08th Ave SE. The site is bounded by Benson Road (I 08 1h Ave SE) to the west, SE 170th Street to the north and a single family residence to the east and south, zoned R-12 and R-18, respectively. The majority of the site is flat while an existing concrete retaining wall and hill slope, each with a maximum 4-foot relief separating the two parcels. The southeast site corner slopes at I 0% slope upgrade from west to east with a maximum 6-foot relief. SCOPE OF WORK The purpose of our services is to evaluate the site soils conditions as a basis for assessing the soil suitability for proposed site structure foundations, road surfacing and subgrade and infiltration recommendations. Specifically, our scope of services for this project includes the following: I. Review of available soils, geologic, topographic information regarding the subject site and adjacent areas with particular emphasis on subsurface information. LD Engineering ccc 2 Cruz/Loranger Site 2. A surface geologic reconnaissance of the site and adjacent areas to identify relevant information. 3. Excavate 6 test pits to a maximum depth of IO feet below ground surface to evaluate the subsurface soil condition. 4. Preparation of a geotechnical report providing our observations of soil conditions at the site pertinent to the proposed foundation work and providing our opinion as to the adequacy of such development. We will also provide criteria for allowable on-site drainage disposal solutions, if feasible. A summary of our findings will be included in a written report along with recommendations and the report will be suitable for submittal to King County with the permit application. If the subsurface conditions are significant, we will also provide a recommendation and cost for additional studies, which may include subsurface explorations such as mechanical soil borings or additional backhoe test pits and an engineering analysis of foundation soil stability. 5. Additional services that may be requested by you and agreed to by LD Engineering LLC. SITE CONDITIONS The project comprises two adjacent parcels, each measuring approximately 212' X 80'; see the Appendix, Site Plan. The highest and lowest site elevations are 428.19' and 415.69' at the southeast corner and midpoint of the southern property line of Parcel B, respectively. The topography of Parcel A is nearly flat, sloping slightly to the west or south at a maximum of 3% slope. Parcel B slopes from the north, east and west to a local low point located near the midpoint of the southern property line. There is a I 0% maximum slope at the site southeast corner, while the central portion of the site slopes at 4%. A duplex and paved parking area exists on Parcel A, while a single-family residence with gravel parking area and 4 sheds occupies Parcel B. The majority of each property is vegetated with grass, while the back corner of Parcel B has an area of brush. No evidence of erosion was observed at the site at the time of our site observations. SUBSURFACE EXPLORATIONS Our subsurface explorations were performed on June 16, 2007. A total of six (6) exploratory test pits were excavated by a backhoe to characterize subgrade conditions of the property. The test pits were extended to 10 feet below ground surface (bgs) with the locations shown on the Appendix, Site Soil Test Pit Location Map. The soil observed in the test pits is shown on the accompanying exploration logs in the Appendix. Exploration locations were determined by tape measurement from available reference points and should be considered accurate only to the degree of the method employed. Exploration elevations were established by a site topographic survey. Samples obtained from the explorations were placed in airtight containers and transported to a soil testing laboratory for further examination. Particle Size Gradation and Water Content Tests were performed on five samples with the results presented in tabular and graphical form in the Appendix. Generally, the site soil is characterized as silty sand encountered throughout the majority of all six (6) boring depths. LD Engineering LLC 3 Cruz/Loranger Site GEOLOGY AND SUBSURFACE CONDITIONS General Geology The geology of the site and surrounding area as taken from the USDA Soil Conservation Service is as follows: Map Unit Description - King County Area, Washington AgC-Alderwood gravelly sandy loam, 6 to 15 percent slopes Hydrological Group C Map Unit Setting - * Elevation: 50 to 800 feet * Mean annual precipitation: 25 to 60 inches * Mean annual air temperature: 48 to 52 degrees F * Frost-free period: 180 to 220 days Map Unit Composition - * Alderwood and similar soils: 95 percent * Minor components: 5 percent Description of Alderwood - Setting * Landform: Moraines, till plains * Parent material: Basal till with some volcanic ash Properties and qualities * Slope: 6 to 15 percent * Depth to restrictive feature: 24 to 40 inches to dense material * Drainage class: Moderately well drained * Capacity of the most limiting layer to transmit water (Ksat): Very low to moderately low (0.00 to 0.06 in/hr) * Depth to water table: About 24 to 42 inches * Frequency of flooding: None * Frequency of ponding: None * Available water capacity: Very low (about 2.5 inches) Interpretive groups * Land capability (nonirrigated): 4s Typical profile * 0 to 12 inches: Gravelly sandy loam * 12 to 27 inches: Very gravelly sandy loam * 27 to 60 inches: Very gravelly sandy loam LD Engineering uc 4 Cruz/Loranger Site Minor Components Norma * Percent of map unit: I percent • Landform: Depressions Bellingham * Percent of map unit: I percent * Landform: Depressions Seattle • Percent of map unit: I percent • Landform: Depressions Tukwila • Percent of map unit: I percent • Landform: Depressions Shalcar * Percent of map unit: 1 percent • Landform: Depressions LD Engineering LLc 5 Cruz/Loranger Site Subsurface Conditions Parcel A is overlain by approximately 2 feet of fill consisting of moist, medium dense, brown silty sand with intermittent stones and rubble, while silty sand with organics comprises the first foot of topsoil on Parcel B. Below the fill/topsoil a medium dense layer of brown silty sand with gravel extends to approximately 3.5 feet bgs. From 3.5 feet bgs to the 10 foot maximum depth of all the borings, dense to very dense, gray silty sand with gravel was encountered. A gradation analysis performed on the silty sand soil samples indicate a silt/sand content ranging from 27% to 40%. Ground Water Groundwater was not encountered in any of the three Parcel A test pits, but was encountered in all of the Parcel B test pits at approximately 3.5-feet bgs. A limited amount of shallow groundwater appears to be perched on top of the dense layer of silty sand in the vicinity of and at the base of the slopes on Parcel B. Infiltration tests were attempted in each of the pits, but were abandoned since the dense layer of silty sand at approximately 4 feet did not allow percolation of standing water after sufficiently long periods of soaking. With respect to hydraulic conductivity the high silt/clay content results in a soil that behaves more like silt or clay and thereby a very low permeably. Therefore, we do not recommend onsite infiltration as a means of stormwater discharge. CONCLUSIONS Based on the results of our site reconnaissance, data review, and subsurface explorations, it is our opinion that the site is suitable for the proposed multi-residential development. Based on the soils encountered and our understanding of the proposed site development, conventional earthwork and foundation support is feasible at the site provided that necessary precautions are taken for the perched, shallow groundwater encounter in the vicinity of the site low point. The high silt/clay soil content will make use of the site soil as fill difficult under wet seasonal conditions. We recommend that the contractor grade the site in as dry a period as possible, especially if the site soil is to be used as fill and be experienced in working with shallow ground water conditions. Conventional foundation support may be utilized for the structure. Pertinent conclusions and geotechnical recommendations regarding the design and construction of the proposed development are presented below. LANSLIDE -EROSION HAZARD AREA Classification The King County Ordinance defines a landslide hazard as 1) one containing slopes equal to or greater than 30% with more than a I 0-foot vertical relief and containing soils described by the Soil Conservation Service (SCS) Soil Survey as having "severe" limitation for building site development due to slope. There are no SAO Landslide Hazards mapped on the King County Landslide Hazard Areas map (see the Appendix) in the vicinity of the site. The maximum site slope is 10% and the soil rating is "somewhat limited" for a building site without a basement. The soils at the site are mapped as "AgC-Alderwood gravelly sandy loam" throughout the entire site, refer to the Appendix, SCS Soil Survey. The Alderwood soils are LD Engineering LLc 6 Cruz!Loranger Site described as having a slight erosion hazard. Therefore the site soil does not meet the technical criterion for either landslide or erosion hazard. Slope Stability Based on our field observations, explorations and experience with the soil type and site conditions, the site soil is generally stable relative to deep-seated slide failure in its present configuration. SEISMIC -LIQUEFACTION Seismic event following an earthquake generates vibrations within soil particles and results in complete loss soil strength. This phenomenon is called Liquefaction and it mainly affects geologically recent deposits of fine-grained sands that are below the groundwater table. Soils of this nature derive their strength from intergranular friction. The generated water pressure or pore pressure essentially separates the soil grains and eliminates this intergranular friction, thus reducing or eliminating the soil's strength. Based on our review of the subsurface conditions, we conclude that the site soils are not susceptible to liquefaction. The near surface soils are in a dense, cemented condition and of a glacially overridden nature. Although a limited perched water table was encounter at the low portions of Parcel B, site soils were not saturated at depths below 3.5 feet. Shaking of the already dense soil with subsequent excess pore pressure is not apt to produce a denser configuration. EARTHWORK Site Preparation All areas to be graded/excavated should be cleared of deleterious matter including any existing structures, foundations, abandoned utility lines, debris and vegetation. Graded areas should be stripped of any forest duff and organic-laden soils. Based on the explorations at the site, we estimate that stripping on the order of 4 to 12 inches will be necessary to remove the sod, root zone and surficial soils containing significant organic material. Areas with deeper, unsuitable organics should be expected in the vicinity of depressions or heavy vegetation. These materials may be stockpiled and later used for erosion control and landscaping/revegetation. Materials that cannot be used for landscaping or erosion control should be removed from the project site. Where placement of fill material is required, the exposed subgrade areas should be compacted to a firm and unyielding surface prior to placement of any fill. We recommend that trees be removed by overturning in fill areas so that a majority of the roots are removed. Excavations for tree stump removal should be backfilled with structural fill compacted to the densities described in the "Structural Fill" section of this report. We recommend that a member of our staff evaluate the exposed subgrade conditions after removal of vegetation and topsoil stripping is completed and prior to placement of structural fill. The LD Engineering LLc 7 CruzJLoranger Site exposed subgrade soil, especially in the area of fill on Parcel A should be probed with a 1/2-inch- diameter steel, as appropriate. Any soft, loose or otherwise unsuitable areas delineated during proof rolling or probing should be recompacted, if practical, or overexcavated and replaced with structural fill, based on the recommendations of our site representative. Any organics encountered in the fill should be removed. Structural Fill The brown silty sand and organics encounter in the top 6" to 12" below the surface should not be used for structural fill, but is suitable for use in landscaped areas. Due to the high content of silt/clay ranging from 27% to 40% in the underlying silty sand, we recommend that site grading occur during a dry seasonal period. The soil will be highly sensitive to moisture and therefore difficult to compact wet of optimum moisture content. All fill material/trench backfill should be placed as structural fill. The structural fill should be placed in horizontal lifts of appropriate thickness to allow adequate and uniform compaction of each lift. Fill should be compacted to at least 90 percent of MOD (maximum dry density as determined in accordance with ASTM D-1557) to within 2 feet of sub grade and 95 percent MOD in the upper 2 feet. The appropriate lift thickness will depend on the fill characteristics and compaction equipment used. We recommend that the appropriate lift thickness be evaluated by our field representative during construction. We recommend that our representative be present during site grading activities to observe the work and perform field density tests. The suitability of material for use as structural fill will depend on the gradation and moisture content of the soil. As the amount of fines (material passing No. 200 sieve) increases, soil becomes increasingly sensitive to small changes in moisture content and adequate compaction becomes more difficult to achieve. During wet weather, we recommend use of well-graded sand and gravel with less than 5 percent (by weight) passing the No. 200 sieve based on that fraction passing the 3/4-inch sieve. If prolonged dry weather prevails during the earthwork and foundation installation phase of construction, a higher (up to 10 to 12 percent) fines content will be acceptable. Material placed for structural fill should be free of debris, organic matter, trash and cobbles greater than 6 inches in diameter. The moisture content of the fill material should be adjusted as necessary for proper compaction. Cut and Fill Slopes All job site safety issues and precautions are the responsibility of the contractor providing services/work. The following cut/fill slope guidelines are provided for planning purposes. Temporary cut slopes will likely be necessary during grading operations. As a general guide, temporary slopes of 1 .5 to I (horizontal to vertical) or flatter may be used for temporary cuts in the upper 3 to 4 feet of the glacially consolidated soils that are weathered to a loose/medium dense condition. Temporary slopes of 3/4 to I or flatter may be used in the unweathered dense to very dense sands and gravels. LD Engineering ccc 8 Cruz/Loranger Site These guidelines assume that all surface loads are kept at a minimum distance of at least one half the depth of the cut away from the top of the slope and that significant seepage is not present on the slope face. Flatter cut slopes will be necessary where significant raveling or seepage occurs. We recommend a maximum slope of2 to I for permanent cut and fill slopes. Where 2 to 1 slopes are not feasible, retaining structures should be considered. Unretained fill material placed on slopes that are steeper than 5 to 1 should be "keyed' into the undisturbed native soils by cutting a series of horizontal benches. The benches should be 1 Y, times the width of equipment used for grading and a maximum of 3 feet in height. Subsurface drainage may be required in seepage areas. Surface drainage should be directed away from all slope faces. Some minor raveling may occur with time. All slopes should be seeded as soon as practical to facilitate the development of a protective vegetative cover or otherwise protected. FOUNDATION SUPPORT We recommend that spread footings for any residence be founded on medium dense or denser native soils or on structural fill that extends to suitable native soils. The soil at the base of the excavations should be disturbed as little as possible. All loose, soft or unsuitable material should be removed or recompacted, as appropriate. A representative from our firm should observe the foundation excavations to determine if suitable bearing surfaces have been prepared, particularly in the areas where the foundation will be situated in fill material. Perimeter foundations exposed to the weather should be at a minimum depth of 18 inches below final exterior grades. Shallow groundwater at the site requires that the footings must be placed above the ground water level. We recommend that spread footings for residence be founded on structural fill that extends to suitable native soils if the shallow ground water level is below the footing elevation. We recommend a minimum width of2 feet for isolated footings and at least 16 inches for continuous wall footings. Footings founded as described above can be designed using an allowable soil bearing capacity of 2,000 psf (pounds per square foot) for combined dead and long-term live loads. The weight of the footing and any overlying backfill may be neglected. The allowable bearing value may be increased by one-third for transient loads such as those induced by seismic events or wind loads. Lateral loads may be resisted by friction on the base of footings or floor slabs and as passive pressure on the sides of footings. We recommend that an allowable coefficient of friction of0.35 be used to calculate friction between the concrete and the underlying soil. Passive pressure may be determined using an allowable equivalent fluid density of 300 pcf (pounds per cubic foot). Factors of safety have been applied to these values. We estimate that settlements of footings designed and constructed as recommended will be less than 1 inch, for the anticipated load conditions, with differential settlements between comparably loaded footings of Y, inch or less. Most of the settlements should occur essentially as loads are being applied. However, disturbances of the foundation subgrade during construction could result in larger settlements than predicted. LD Engineering uc 9 Cruz/Loranger Site FLOOR SLAB SUPPORT Slabs-on-grade (garage or floor) should be supported on medium dense or denser native soils or on structural fill prepared as described in the Structural Fill section of this report. We recommend that floor slabs be directly underlain by a minimum 4-inch thickness of coarse sand and/or gravel containing less than 3 percent fines. The drainage material should be placed in one lift and compacted to an unyielding condition. A synthetic vapor barrier is recommended for the control of moisture migration through the slab, in particular where adhesives are used to anchor carpet or tile to the slab. A thin layer of sand may be placed over the vapor barrier and immediately below the slab to protect the liner during steel and/or concrete placement. A sub grade modulus of 400 kcf (kips per cubic foot) may be used for floor slab design. We estimate that settlement of the floor slabs designed and constructed as recommended, will be '/,- inch or less over a span of 50 feet. PAVEMENT AREAS Pavement area subgrades should consist of compacted structural fill. All loose material and material containing organic material should be removed from pavement subgrades and structural fill should be placed up to pavement subgrade. The grade should be brought up by placing and compacting structural fill to 90 percent of the material's maximum dry density, except for the top I-foot which should be compacted to 95 percent (ASTM Test Designation Q-1557 -Modified Proctor). We recommend placing a 4 inch thick base of crushed rock minus (5/8" or I 1/4 directly below the driveway pavement above the compacted structural fill. The native soils encountered at the site during our subsurface exploration program appeared to be compact below I foot and are likely to be acceptable for structural fill. Density tests can be conducted in these areas provided that an applicable proctor compaction test has been conducted. A proof-roll test may also be acceptable for confirming the firm and unyielding state of the pavement subgrade. A proof-roll test consists of a LD Engineering, LLC representative monitoring a fully loaded dump truck or large steel drum roller rolling over the sub grade to observe any deflection of the pavement subgrade. SITE DRAINAGE All ground surfaces, pavements and sidewalks should be sloped away from the residence and associated structures. Surface water runoff should be controlled by a system of curbs, berms, drainage swales, catch basins and then dispersed into vegetated areas, and/or conveyed to the site's storm water discharge system. We recommend that conventional roof and footing drains be installed for structures. The foundation drains and roof downspouts should be tightlined separately to an approved discharge system. LD Engineering LLc 10 Cruz/Loranger Site Drainage from the driveway area should be sheet flowed to the adjacent vegetated portions of the site and/or conveyed offsite by a drainage system. We do not recommend onsite infiltration due to the low permeability soil that underlies the site.

A PORTION OF NW 1/4 OF THE SE 1/4 OF SECTION 29-23-5 KING COUNTY, WASHINGTON EROSION AND SEDIMENT CONTROL NOTES 1. Approval of this erosion and sediment control (ESC) pion does not constitute an approval of permanent road or drainage design (e.g., size and location of roads, pipes, restrictors, channels, retention facilities, utilities, etc.). 2. The implementation of these ESC plans and the construction, maintenance, replacement, and upgrading of these ESC facilities is the responsibility of the applicant/ESC supervisor until all construction is approved. 3. The boundaries of the clearing limits shown on this plan shall be clearly flagged by a continuous length of survey tape (or fencing, if required) prior to construction. During the construction period, no disturbance beyond the clearing limits shall be permitted. The clearing limits shall be maintained by the applicont/ESC supervisor for the duration of construction. 4. The ESC facilities shown on this pion must be constructed prior to or in conjunction with all clearing and grading so as to ensure that the transport of sediment to surface waters, drainage systems, and adjacent properties is minimized. 5. The ESC facilities shown on this plan ore the minirnum requirements for anticipated site conditions. During the construction period, these ESC facilities shall be upgraded as needed for unexpected storm events and modiiied to account for changing site conditions (e.g., additional sump purnps, relocation of ditches and silt fences, etc.). 6. The ESC facilities shall be inspected daily by the applicant/ESC supervisor and maintained to ensure continued proper functioning. Written records shall be kept of weekly reviews of the ESC facilities during the wet season (Oct. 1 to April 30) and of monthly reviews during the dry season (May 1 to Sept. 30). 7. Any areas of exposed soils, including roadway embankments, that will not be disturbed for two days during the wet season or seven days during the dry season shall be irnrnediately stabilized with the approved ESC methods (e.g., seeding, mulching, plastic covering, etc.) . 8. Any area needing ESC measures not requiring immediate attention shall be addressed within fifteen (15) days. 9. The ESC facilities on inactive sites shall be inspected and maintained a minimum of once a month or within forty-eight ( 48) hours following o storm event. 10. At no time shall more than one (1) foot of sediment be allowed to accumulate within o catch basin. All catch basins and conveyunce lines shall be cleaned prior to paving. The cleaning operation shall not flush sediment-laden water into the downstream system. 11. Stabilized construction entrances and roads shall be installed at the beginning of construction and maintained for the duration of the project. Additional measures 1 such as wash pads, rnay be required to ensure that all paved areas are kept clean for the du1·a\ion of the project. 12. Any permanent flow control facility used as a temporary settling basin shall be modified with the necessary erosion control rneosures and shall provide adequate storage capacity. If the facility is to function ultimately as an infiltration system, \he temporary facility must be graded so that the botto1n and sides are at least three feet above the final grade of the permanent facility. 13. Where straw mulch for temporary erosion control 1s required, it shall be applied at a rn1n1mum thickness of 2 to 3 inches. 14. Prior ta the beginning of the wet season (Oct. 1), all disturbed areas shall be reviewed to identify which ones can be seeded in preparation for the winter rains. Disturbed areas shall be seeded within one week of the beginning of the wet season. A sketch map of those areas to be seeded and those areas to remain uncovered shall be submitted to the DOES inspector. The DOES inspector can requir-e seeding of additional areas in order to protect surface waters, adjacent properties, or drainage facilities. ··-~-- STRUCTURAL NOTES 1. These plans are approved for standard road and drainage improvements only. vaults, and retaining walls require a separate review and approval by ODES prior 14.20). Plans for structures such as bridges, to construction (KCC 16.04. 16. 70, 2. Rockeries are considered to be a method of bank stabilization and erosion control.
