These facts are in reference to King County tax parcel identification number 726320-0020 located at 29929 Military Road South, Federal Way, WA 98003. 1. Proposal — The applicant proposes to subdivide one existing 0.74-acre single-family residential lot into three lots, one private ingress/egress tract, and one landscaping tract. As shown on the short plat, the following are total square footage for each lot/tract: Lot 1 — 7,346 square feet; Lot 2 — 7,347 square feet; Lot 3 — 7,292 square feet; Tract A — 6,891 square feet; and Tract B — 833 square feet. 2. Review Process — Pursuant to FWCC Chapter 20, the proposed short plat is subject to administrative review and decision rendered by the Director of Community and Economic Development. The proposal has been reviewed by staff from Community and Economic Development, Public Works, Lakehaven Utility District, and South King Fire and Rescue. City staff has used the following FWCC development regulations when reviewing the short subdivision application: Chapter 19 `Planning & Development;' Chapter 20 `Subdivisions;' Chapter 21 `Surface & Stormwater Management;' and Chapter 22, `Zoning.' 3. Site Profile — The subject property is located in the north eastern portion of the city, along the west side of Military Road South between South 299`h Street and South 30151 Street. Access to the subject property is via South 300t' Street. The subject property is rectangular shaped, with 30 feet of right- of-way street frontage along South 300'1' Street and 373 feet of depth. According to available King County and City of Federal Way property information, historical improvements on the property include a 540 square -foot single-family residence constructed in 1946, and one outbuilding. The 1973 King County soils survey map lists the soils type as Alderwood gravelly sandy loam (AgB), 0-6 percent slopes. The Alderwood series contains moderately well drained soils consisting of predominately Arents and Alderwood material. Runoff and erosion hazards are medium. The site topography is flat with an elevation of 488 feet at the western border, 490 feet in the central portion and 488 feet at the eastern border. The subject property is located within the Lower Green River watershed. 4. Comprehensive Plan & Zoning — The subject property is within Single -Family High Density Residential and RS 7.2 designation. ' The application was deemed complete prior to the city's adoption of the currently used Federal Way Revised Code and is therefore vested to its predecessor Federal Way City Code. 5. Density Regulations — Minimum lot size for RS 7.2 zoning designations is 7,200 square feet or approximately 6 single-family dwelling units per acre. The proposed 3-lot short subdivision meets minimum density standards of FWCC 22-631 `Detached dwelling unit.' 6. State Environmental Policy Act (SEPA) —The proposal is exempt from a SEPA threshold determination pursuant to Washington Administrative Code (WAC) 197-11-800(6)(a). 7. Critical Areas — The city's Critical Areas inventory shows no streams, wetlands, geologically hazardous areas, wellheads, etc. on the subject property or within their respective buffers. 8. Public Notice & Comment — A Notice of Land Use Application for the short subdivision was published in the Federal Way Mirror and posted at the subject property and city designated notice boards on October 24, 2009. No written comments were submitted regarding the short subdivision application. 9. Open Space — Pursuant to FWCC 20-156(b), all residential subdivisions shall provide open space in the amount of 15 percent of gross land area of the site or 4,851 square feet. The applicant has provided a 10-foot-wide Type III landscape buffer totaling 833 square feet adjacent to Military Road South. As permitted by FWCC 20-178, the landscaping tract will be credited (limited to 2 percent of the gross land area or 647 square feet) as provided open space. The applicant has requested to satisfy the remaining open space obligation as a fee -in -lieu payment to the Parks Department. The applicant will be required to pay 13 percent of the assessed value of the subject property at the time of plat recording or defer the payment as permitted by Federal Way Revised Code 19.100.070(1). Pursuant to FWCC 20-178, a homeowners' association will be established for ownership and maintenance responsibilities of the landscape tract. As conditioned, the applicant will provide a short plat note referencing the HOA document recording number and submit HOA paperwork to the department for review prior to short plat recording. 10. Landscape Tract — A ten -foot -wide Type III landscaping strip has been provided as the short subdivision is adjacent to a city designated arterial (Military Road South). The landscape tract (Tract B) will be equally owned and maintained by the short subdivision's homeowners' association. Tract B has been credited towards the open space requirements in the amount of 2 percent. As a condition of short subdivision approval, the applicant shall submit HOA documents for department review prior to recording and add the following to the short plat notes: (1) a reference to the HOA document recording number; and (2) trees and vegetation shall not be removed from Tract B without approval granted from the Director of Community and Economic Development. 11. Significant Trees — The subject property will retain all five significant trees (4 western red cedars and 1 douglas fir) and therefore requires no replacement. 12. Clearing and Grading — As the site is relatively flat, only limited grading will be necessary, primarily for stormwater and right-of-way improvements. Temporary Erosion and Sedimentation Control (TESC) measures will include a rock entrance, silt fence, and inlet protection. The city's Public Works Department will periodically inspect the construction site and enforce TESC measures. 13. Concurrency — The city's Traffic Division reviewed the applicant's concurrency application and concludes the proposed short subdivision will generate 3 peak hour trips. A Capacity Reserve Certificate was issued November 25, 2008. Traffic Division staff have determined the new trips Statement of Facts Page 2 Gehring Short Plat File 08-102706-00-SU/Doc I D 59106 1 generated by the short subdivision will impact the following project in the city's six -year Transportation Improvement Plan (TIP) as identified in the Federal Way Comprehensive Plan. The applicant will be required to mitigate the impacts via a pro -rats share payment of $1,495 for the capital improvement. Payment is due to the city at the time of plat recording.

Frontage and Internal Road Improvements — Access to the site will be via a new public 32-foot extension from South 300`h Street. The applicant will be required to construct the 20-foot wide driveway entrance per Public Works Standard DWG 3-6. Internal roadway will be a 26-foot-wide private ingress, egress and utilities easement per Standard DWG 3-2DD with an emergency vehicle hammerhead turnaround. The hammerhead will be a recorded easement with the intent of emergency use only and therefore will not be considered a vehicle access easement for lot size purposes. Existing Military Road South access will be permanently closed. A dedication of approximately 20 feet of right-of-way along Military Road South will be required for future capital improvements. The dedication will be conveyed to the city via Statutory Warranty Deed prior to plat recording and must contain clear title. 15. Stormwater — The proposed development meets criteria requiring full drainage review. Development of the site will create additional runoff from new impervious surfaces such as streets, driveways, and rooftops. The applicant will be required to design a facility which meets the requirements of the city's amended version of the 1998 King County Surface Water Design Manual. Stormwater from the pollution generating surfaces (internal road and driveways) will be conveyed to a biofiltration swale within the ingress, egress and utilities easement. Rooftop stormwater will be conveyed to infiltration trenches on each lot. Flow control will not be required as the project does not exceed thresholds from the existing condition. 16. Fire Protection — South King Fire and Rescue has accepted the hammerhead easement as an alternative to a typical cul-de-sac turnaround. As a condition of their acceptance, sprinklers are required on lots 2 and 3. As a condition of short plat approval, the applicant shall include plat note description of the fire sprinkler requirement. 17. Water and Sewer — The applicant proposes to serve the short subdivision with a public water supply and distribution system managed by the Lakehaven Utility District. The June 2, 2008, Certificate of Water Availability indicates Lakehaven's capacity to serve the proposed development via an existing water main and water service connection application. The applicant proposes to serve the short subdivision by a public sewer system managed by Lakehaven Utility District. A June 2, 2008, Certificate of Sewer Availability indicates the district's capacity to serve the proposed development with a side sewer service connection, sewer trunk improvements, and service connection permits. 18. Engineering Requirements — The applicant must obtain authorization to proceed from the Public Works Department prior to construction of plat infrastructure. 19. Homeowners' Association — As the short subdivision contains two tracts containing required landscaping, streets, and stormwater facilities, the applicant will be required to form a Homeowners' Statement of Facts Page 3 Gehring Short Plat File 08-102706-00-SU/no.. t.n. 59106 Association (HOA) to administer responsibilities and duties of the residents of the development. Such duties shall include but not be limited to the maintenance and repair of internal roadways, stormwater facility, and landscaped areas. As a condition of approval, the applicant shall draft documents related to the formation of the HOA and shall be noted on the plat document and recorded concurrently with the short subdivision. 20. Conditions of Approval —Planning staff recommends the following conditions of approval be incorporated into the short subdivision decision. Unless otherwise permitted in FWRC 18.30.280, all conditions shall be met prior to plat recording: (1) The applicant shall submit to the city for review, a Conditions, Covenants and Restrictions (CC&Rs) document detailing the duties and obligations of the homeowners regarding shared tract maintenance within the short subdivision. The CC&Rs shall contain, but not be limited to repair and maintenance activities associated with: internal roadway; stormwater facility; and landscaping within Tract B.

Let me know if you have any questions or need additional information. HAZMAT INVENTORY STATEMENT • The eastern one -quarter (approximately) of the parcel is within the 1-Year Capture Zone, and the western three- quarters (approximately) of the parcel is within the 5-Year Capture Zone, for Lakehaven's Well 9. The typical materials & activities associated with this type of development are not normally cause for any significant concern with regard to wellhead protection, so long as standard precautionary spill -protection measures are considered and employed during design & construction. WATF R A separate water service connection application submitted to Lakehaven is required for each new service connection to the water distribution system, or any modification to an existing water service connection. SEWER As previously noted, in lieu of the typical re uirement for a Developer Extension Agreement, separate sewer service connections for the proposed single-family residential development may be allowed by Lakehaven. Owner/developer/applicant will need to submit a brief written request (letter, email, or fax) separately to Lakehaven for this standards modification. Lakehaven will review the request and provide a response, typically within two weeks from receipt of this type of request, although Lakehaven continues to encourage owners/developers/applicants to submit this separately to Lakehaven, early in the pre-design/planning phase to avoid delays in overall project development. If the above standards modification if approved by Lakehaven, a portion of the property will be subject to Temporary Service Charges and execution of a temporary service agreement(s), as part of Lakehaven's service connection/permitting process. The resubmitted information does indicate Tract "A" as a (necessary) private sewer easement for the benefit of the property's proposed sewer service lines. Owner/developer/applicant will need to submit a brief written request (letter, email, of fax) to Lakehaven for modification to the standard requirement of no horizontal alignment changes in public right-of-way (ROW) for sewer service lines. When received, Lakehaven will coordinate further review and seek approval from the jurisdictional ROW agency, providing a response when the ROW agency has notified Lakehaven of its determination. This type of request can be submitted with, or prior to, submittal of the associated service connection application(s). <<08-102706-00-SU. pdf» Brian Asbury Engineering Technician III Lakehaven Utility District f lL#:_lfwww.lakehaven.orglstandards.htm FAX 253-529-4081 NOTE: Lakehaven Utility District neither warrants nor guarantees the accuracy of any facility information shown.

The driveway approach has been revised to City standards. 4) The plans (Sheet PG1) indicate retaining walls along each side of the water quality bio-Swale, with a maximum height of 3.5 feet. According to Section 6.3.1.2 (6.b) of the 1998 King County Surface Water Design Manual (KCSWDM), only 1 wall (preferably the north wall) should exceed 2 feet in height. Plans have been revised to show actual height of retaining walls along each side of the bioswale. The revised design has been discussed with Kevin Peterson. 5) Since infiltration is proposed for each new residence as well as for road runoff, a soils report shall be prepared that meets the requirements of Section 5.4.1 of the KCSWDM. The soils report is included with re -submittal package. We appreciate your assistance with this project. Please feel free to contact me if you have questions regarding this resubmittal.

T 206.658.0125 ■ F 206.658.0127 ■ www.TheConceptGrp.com December 30, 2008 Ken Miller, P.E. Deputy Public Works Director City of Federal Way Public Work Development Services Division P.O. Box 9718 Federal Way, WA 98063-9718 Subject: Private Driveway Modification Request Gehring Short Plat (File #08-102706-00-SU) 29929 Military Road South Dear Ken: EC -INFO JAN 0 7 2009 CITY CF FEDERAL WAY This letter is written to request a variance approval for the private driveway design for the above referenced three (3) lot short plat. Applicable Standard Drawings • The City of Federal Way Development Standard DWG No. 3-2DD requires a 25-ft tract width with a 20-ft wide driveway pavement to serve three (3) or four (4) lots. • DWG No. 3-2CC requires a 20-feet tract width with a 16-feet wide driveway pavement width serving up two (2) lots. Background Information Because the existing house currently takes access from a driveway along Military Road South, the property owners have the following options: • Option A: Maintain existing driveway on Military Road South for one lot and provide a new access on South 300th Street for additional two (2) new lots • Option B: Remove existing driveway on Military Road South and provide a new access on South 300th Street for all three (3) lots A pre -application meeting was held on March 13, 2008 with the City's Development Review Committee, property owners and me. It was determined that the four (4) lot option was not feasible due to minimum lot size requirements. At this time, City staff expressed the preference to remove the existing access on South Military Road, a principal arterial, so that all three lots take access from the less congested South 300th residential Street. For this pre -application meeting, The Concept Group (TCG) submitted two conceptual site plans showing proposed building setback locations (see attached Conceptual Site Plans. Also attached are Exhibits A and B showing my notes from the discussions regarding the proposed site plans. The setback requirements were discussed; however, there was no mention regarding the proposed frontage setback on the conceptual plans facing away (perpendicular) A NEW DIMENSION OF DESIGN PERCEPTION Gehring Right -of -Way Modification Rey, Page 12 12/30/08 from the private access road. Subsequently, TCG submitted a proposed site plan (see attached Figure A) with our Preliminary Short Plat application to maximize the buildable footprint of the property. This layout allows for a building depth of 43.5 ft. On June 30, 2008, we received correspondence from Joanne Long -Woods informing us that the front setback needed to be oriented to face the private access driveway. In order to accommodate this requirement and still meet Public Works DWG No. 3-2DD for a 3 lot private driveway, the depth of the building will be reduced to only be 29.5-ft (see attached Figure 9). This would create a low -value narrow house that would not be aesthetically pleasing to the neighborhood. On August 11, 2008, 1 meet with Joanne Long -Woods and other representatives of the City's Development Review Committee. During the course of this meeting, it was determined that that was no possibility of an approval from the planning department to allow the front setback of the building to face away from the private driveway. Variance Request TCG proposes to use DWG No. 3-2CC for the design of the private driveway. We request your approval of this modification request for the following reasons: • City staff requested that the existing driveway on Military Road South be removed. It is to the benefit of the City to remove this existing access from Military Road South due to existing speeds and limited site distance coming from the driveway. DWG No. 3-2CC allows for a larger building footprint to promote a house design consistent with the neighboring properties (see attached Figure Q. Structures on Lot 2 and 3 will be sprinklered so Fire Department access is not an issue. The property owners agree that it would be beneficial to close the existing driveway on Military Road South. However, if this reduces the value of their property by limiting the size of the new buildings to narrow 29.5-ft deep structures, then the will be forced to reconsider the access issues. I respectfully request that you grant an approval for this Right -of -Way Modification since it is to the mutual benefit of the City and property owner to allow for all three lots to access from South 300th Street. I appreciate your assistance with this project. Please feel free to contact me if you have questions. Sincerely, The C ncept Group, Inc. Anna T. Nguyen, P.E. I Project Manager The Concept Group, Inc.

Prior to Public Works approval of the preliminary short plat, the applicant shall address the following comments: Short Plat — 1) The Title Report is over 30-days old. An updated Title report is required. 2) The short plat pages are not printed on current City Title Block pages. If the surveyor does not have the current Title Block, the electronic versions can be sent via e-mail. 3) The Section -Township -Range given is incorrect. The site appears to be located in the NE 1/4of the SE 1/4of Section 4, Township 21 North, Range 4 East. The surveyor should verify. 4) Add the City File number (08-102706-00-SU) to the space provided in the Title Block. 5) The surveyor shall provide a statement, indicating the equipment and procedures used for the survey. Preliminary Engineering Plans — 1) The applicant is required to either construct the street improvements on Military Road South, and show the improvements on the plans, or submit a request to waive the required improvements. A processing fee of $86.50 shall accompany the waiver request. 2) The Section -Township -Range given on Sheet CV is incorrect. See Short Plat comment 2, above. 3) A City standard driveway approach is required at the connection of the private access road and the public roadway. 4) The plans (Sheet PG1) indicate retaining walls along each side of the water quality bio-swale, with a maximum height of 3.5 feet. According to Section 6.3.1.2 (6.b) of the 1998 King County Surface Water Design Manual (KCSWDM), only 1 wall (preferably the north wall) should exceed 2 feet in height. 5) Since infiltration is proposed for each new residence as well as for road runoff, a soils report shall be prepared that meets the requirements of Section 5.4.1 of the KCSWDM. 6) Comments pertaining to the preliminary engineering plans are preliminary in nature.

Box 972 Cehurst, Washington 98062 Attention: Mr. Brad Gehring Subject: Infiltration Study Gehring Short Plat 29929 Military Rd. South Federal Way, Washington 98003 Dear. Mr. Gehring: At your request, we are pleased to present this report summarizing textural analysis of site soils and providing design recommendations for infiltrating storm water at the subject site. The recommendations contained in this study are based on infiltration testing and textural analysis of site soils sampled at proposed infiltration locations as defined by The Concept Group data provided to us. Our scope of work for this study included the following: ■ Excavating four test pits, one at each of the proposed infiltration areas; ■ Conducting laboratory tests on the representative samples of the soils; • Performing infiltration tests at two of the proposed locations; • Interpreting the data, in order to provide our recommendations for infiltration rates for the Civil Engineer's design. - The infiltration tests were performed using the EPA falling Head Percolation Test Procedure from the Design -Manual-- On -Site Wastewater Treatment and Disposal Systems, EPA, 1980.

Storm water from the proposed development will be disposed of using infiltration systems designed by The Concept Group based on our analysis of site soils. The roof run-off infiltration systems will be located on the West side of the lots, and the Tract "A" access road infiltration area between St 12+00 to St 13+00. The infiltration trenches for the storm water systems will be underlain by sandy gravel to sandy silt with gravel, type soils. These soils were loose to dense, suitable for infiltration. No ground water was encountered during our exploration test pits at the proposed infiltration locations. Moderately weathered glacial till consisting of sandy gravel was encountered on the site at three to four feet below existing grade. Based on the anticipated bottom of facility elevations, the planned infiltration of storm water should not be adversely impacted by the presence of till which has moderately low permeability. Infiltration Evaluation Our subsurface exploration was conducted on August 29a', 2008. Four test pits were excavated within the proposed infiltration areas as depicted on the site plan Reference Sheet UT I, Sheet 5 of 8 The Concept Group. We have denoted the approximate locations of the test pits on the plan sheet included in this report labeled TP-1 to TP-4. The test pit logs, grain size analysis data from Krazan, and infiltration test results are summarized for your convince. Please refer to the test pit logs for a more detailed description of the conditions encountered at each location. Summary Test Infiltration Soils Tested infiltration Location Test Depth Rate (iph) TP-1 1.5 Feet SM 5 inch/hr TP-2 1.5 Feet SM 6 inch/hr � 2�r Brad Gehring Development Page 3 September 8, 2008 Infiltration Recommendations Based on the results of our infiltration tests and observed soil conditions, in our opinion, infiltration of storm water runoff should be feasible in the proposed areas. Based on our infiltration tests and review of the King County Surface Water Design Manual, Section 5.4.1 the following infiltration values and factors of safety should be used: • Measured infiltration rate: 5 inch/hr • F testing = 0.30 (EPA Test Method) • F plugging = 0.8 (for fine sands and loamy, sands) ■ F geometry = The Concept Group ■ D = Depth to maximum wet -season water table or nearest impervious layer not reached, test pits terminated at 8 feet below existing grade. W = width of the facility, The Concept Group to determine Limitations Our recommendations and conclusions are based on the site materials observed, selective laboratory testing and engineering analyses, the design information provided to us, and our experience and engineering judgment. The conclusions and recommendations are professional opinions derived in a manor consistent with that level of skill and care ordinarily exercised by other members of the profession currently practicing under similar conditions in this area. No warranty is expressed or implied. The recommendations submitted in this report are based upon data obtained from the test pits, infiltration tests, laboratory test data, and our visual observations. Soil and groundwater conditions between test pits may vary from those encountered. The nature and extent of variations between exploratory locations may not become evident until construction. If variations do appear, a representative from our office should be requested to reevaluate the recommendations of this report and to modify or verify them in writing prior to proceeding with the construction. Additional services TJ Engineering Consultants Inc. has provided only the specific services requested and outlined in the scope of this report. No other conclusions should be derived from the geotechnical data gathered from our site exploration without further consultation from our office. TJ Engineering Consultants Inc. should be retained to provide geotechnical services during construction. This is to observe compliance with the design concepts, specifications or recommendations, and allow design changes in the event subsurface Brad Gehring Development September 8, 2008 Page 4 conditions differ from those anticipated prior to the start of construction. We do not accept responsibility for the performance of the foundation or earthwork unless we are retained to review the construction drawings and specifications, and to provide construction observation and testing services. We trust this information meets with your needs. If you have any questions, please don't hesitate to call. Respectfully submitted, TJ Engineering Consultants, Inc. 1 r� Randall E.

All construction based on this report shall be stopped and shall not proceed until the impact of the changes can be reflected in a supplement report. 2. This report is based on limited subsurface exploration. During construction, if soils conditions are found that are significantly different from those identified in this report, construction should stop until those items affected by the changed conditions can be identified and adjusted, if needed to reflect the changed conditions. 3. This report is prepared for the sole use of client for the purpose of subdividing the property located at 29929 Military Road South in Federal Way, Washington. All other uses are expressly prohibited without prior written approval from the engineer. 4. All construction related to the drainage system for this project will be in accordance with the 1998 King County Surface Water Design Marival and the City of Federal Way current standards unless specifically mentioned in this report and/or approved by the City of Federal Way. Gehrinq Short Plat — Preliminary TIR May 2008 SECTION 1: PROJECT OVERVIEW The property is located at 29929 Military Road South in the City of Federal Way, Washington. There is currently one (1) single family residence on the property. The project proposes to short plat the existing parcel into three (3) single family residential lots. The existing house and shed will be demolished. Proposed improvements include the construction of three (3) single-family structures, a Private Access/Utility tract, associated utilities and stormwater management facilities. Site Information Refer to Appendix A for the Vicinity Map and site photos of this project. Location: 29929 Military Road South; Federal Way, Washington 98003 Section/Township/Range: QW o SW ' Sec. 3 .23N, 4E of W.M. Nf1l`>` 5 I Size: 31,372 sq ft (approximately 0.72 acre) City, County, State: Federal Way, King County, Washington Governing Agency: City of Federal Way Design Criteria: 1998 King County Surface Water Manual Water and Sewer District: Soos Creek Water & Sewer District L Drainage Basin The entire property drains to one basin with a contributing area of 0.72 acres. The general topography of the site slopes from northwest to southeast. Elevations on the site vary from a high point of 490 feet at the northern property line to 488 feet at the southern property line, with grades varying from 0.5% to 5.0%. Soils Information Soils Survey The Soil Survey prepared by the United States Department of Agriculture Natural Resource Conservation Service, indicates the soil type within the project as Ag6 (Alderwood gravelly sandy loam), SCS Hydrologic Soil Group C. This Alderwood soil series contains moderately well drained soils consisting predominately of Arents and Alderwood material with slopes between zero (0) to six (6) percent. Runoff and erosion hazards from this soil type is medium. This series of soil is suitable for urban development. The KCRTS equivalent soils group, as defined in Table 3.2.2.13 of the 2005 King County Surface Water Manual (KCSWM), is Till. The Concept Group Page 1 Gehring Short Plat — Preliminary TIR Refer to Appendix 8 for the Soils Survey map. SECTION 2: CONDITIONS AND REQUIREMENTS 2008 Existing Site Hydrology There is currently one (1) single family residence on the property. The site grades generally from northeast to southwest. Stormwater runoff presently infiltrates to native soils. During heavy rainfall events, stormwater sheet flows in an easterly direction towards the drainage ditches on Military Road South. Developed Site Hydrology The project proposes to short plat the existing parcel into three (3) single family residential lots. Each of the new residential lots will consist of a total of approximately 2,400 sq ft of new impervious surface with the remainder of the new lots consisting of landscape and lawns. Stormwater for the roof, driveway and Private Access Tract will be infiltrated to native soils. Refer to the Drainage Plan in Appendix C for the proposed storm drainage design. Design Requirements The 1998 King County Surface Water Manual sets forth the drainage requirements for this project. This the proposed drainage facilities have been designed to meet or exceed the 1998 KCSWM using the design procedures set forth in the 2005 KCSWM. The drainage requirements are summarized in Table 1. Table 1 -jurisdictional Requirements Peak Run-off Control: N/A - based on 0.1 cfs exemption Water Qualit Basic treatment menu Conveyance: 25- ear developed flow Downstream Analysis: Level 1 SECTION 3: LEVEL 1 OFFSITE ANALYSIS Downstream Analysis Stormwater runoff presently infiltrates to native soils. During heavy rainfall events, stormwater sheet flows in an easterly direction toward Military Road South. Stormwater runoff is conveyed in a series of grass -lined ditches and driveway culverts along Military Road South. There is no sign of erosion within a quarter mile of the project. _J The Concept Group Page 2 __J Gehring Short Plat - Preliminary TIR May 2008 Discharge at Natural (Existing) Location �i Stormwater presently infiltrations to native soils. During heavy rainfall events, stormwater may sheet flow to the ditches along Military Road South. SECTION 4: FLOW CONTROL / WATER QUALITY ANALYSIS & DESIGN Flow Control 1 This project will create approximately 13,925 square feet of new impervious surface. However, per the Sizing Credits for Use of Flow Control BMP's on page 1-41 of the 2005 KCSWM, any area infiltrated per the requirement in Section C.2.2 of Appendix C 1 will not be counted in the total new impervious area for flow control facility sizing ( requirements. The runoff from the new impervious areas on the proposed lots will be infiltrated; therefore, for flow control sizing calculation purposes, this project will create 1 approximately 900 square feet of impervious surface of right-of-way improvements that will not be collected in the proposed infiltration trenches. Flow control facilities are not required because the project creates less than 0.1 cfs increase in discharge from the existing condition for the 100-year storm event per the KCRTS data below. Refer to Appendix D for flow control calculations. Refer to Appendix D for flow control calculations. Infiltration Facility Design A soils analysis was performed and it was determined that the project soils can be classified as coarse sand. Per section C.2.2.3, infiltration trenches must be at least 20 feet in length (40 square feet bottom area) per 1,000 square feet of impervious surface based on a 2 feet wide bottom. The infiltration trenches for the roof drains have been designed with an overflow outlet to sheet flow storm water during heavy rainfall events. Refer to Table 2 and Appendix D for infiltration trench calculations and details. Table 2 — Infiltration Facility Design Areas (SF) New Impervious Surface Required Infiltration Bottom Area Provided Infiltration Bottom Area 2,400 (lot 1) 96 100 2,400 (lot 2) 96 100 2,400 (lot 3) 96 100 access driveway + 20% overflow 280 300 } Drainage Analysis (KCRTS) 1j The King County Runoff Time Series (KCRTS) Hydrologic Model is the required ., methodology under the 1998 King Coun Surface Water Desi n Manuel for sizing b detention facilities. The project Is ocated in the Basic Flow Control Area. Tables 3-5 summarize the KCRTS inputs.

With the proposed infiltration trenches the 100-year peak flow rate of the developed site is less than the existing condition due to the infiltration credits. Table 6 — 100 Year Peak Runoff Rates (cfs) Existing Condition Developed Condition Difference in Discharge 0.156 0.085 decrease of 0.071 Water Quality Although the project will create 13,925 square feet of new impervious surface, approximately 7,925 square feet is pollution -generating impervious surface (PGIS). PGIS is defined as "an impervious surface considered to be a significant source of pollutants in surface and storm water runoff. Such surfaces include those subject to vehicular use or storage of erodible or leachable materials, wastes, or chemicals, and which receive direct rainfall or the run-on or blow-in of rainfall." Non-metal rooftops are not considered PGIS; therefore, are not included in the PGIS area calculations. In accordance with the 1998 King County Surface Water Manual, basic water quality treatment will be provided for the 6-months storm event for this project. A biofiltration Swale is proposed upstream of the infiltration trench to treat 60% of the 2-year developed flow rated as determined using the KCRTS model with the 15-minute time steps. Refer to Table 7 and Appendix D for biofiltration calculations and details. �) Table 7 — Biofiltration Swale Design I PGIS Area Required Swale Provided Swale Dimensions Dimensions 7,925 SF 1.91 FT x 73.7 FT 2.0 FT x 100 FT The Concept Group Page 4 J wJ Gehring Short Plat - Preliminary TIR May 2008 SECTION 5: CONVEYANCE SYSTEM The conveyance system has been sized to convey the 25-year developed flow rate based on the rational method.

SECTION 6: SPECIAL REPORTS AND STUDIES There are no special reports or studies are expected to be prepared for this project. SECTION 7: OTHER PERMITS Permit for this project included: • Short Plat Approval • Building Construction Permit • Clearing & Grading Permit SECTION 8: CSWPP (EROSION CONTROL) ANALYSIS AND DESIGN All erosion and sediment control measures shall be governed by the requirements of the City of Federal Way. An Erosion and Sedimentation Control plan has been prepared to assist the contractor in complying with these requirements and designed to prevent sediment -laden run-off from leaving the site during construction. Refer to Appendix E for Erosion Control plans and details. j The erosion potential of the site is influenced by four major factors: soil characteristics, vegetative cover, topography, and climate. Erosion/ sedimentation control is achieved by a combination of structural measures, cover measures, and construction practices that are tailored to fit the specific site. Construction Sequence and Procedure 1 Prior to the start of any grading activity upon the site, all erosion control measures, including installation of a stabilized construction entrance, shall be installed in accordance with the construction documents. The best construction practice will be employed to properly clear and grade the site and to schedule construction activities. The planned construction sequence for the construction of the site is as follows: J The Concept Group Page 5 __J Gehring Short Plat - Preliminary TIR May 2008 - i 1. Pre -construction meeting. 2. Post sign with name and phone number of ESC supervisor (may be consolidated with the required notice of construction sign). -� 3. Flag or fence clearing limits. 4. Install catch basin protection if required. 5. Grade and install construction entrance(s). 6. Install perimeter protection (silt fence, brush barrier, etc.). 7. Construct sediment ponds and traps. 8. Grade and stabilize construction roads. 9. Construct surface water controls (interceptor dikes, pipe slope drains, etc.) simultaneously with clearing and grading for project development. 10. Maintain erosion control measures in accordance with King County standards and manufacturer's recommendations. 11. Relocate erosion control measures or install new measures so that as site conditions change the erosion and sediment control is always in accordance with the King CountyErosion and Sediment f'ontrol Standards. ? 1 12. Cover all areas that will be unworked for more than seven days during the dry season or two days during the wet season with straw, wood fiber mulch, compost, plastic sheeting or equivalent. 13.Stabilize all areas that reach final grade within seven days. 14.Seed or sod any areas to remain unworked for more than 30 days. 15. Upon completion of the project, all disturbed areas must be stabilized and BMPs } removed if appropriate. Trapping Sediment Structural control measures will be used to reduce erosion and retain sediment on the construction site. The control measures will be selected to fit specific site and seasonal conditions. The following structural items will be used to control erosion and sedimentation - processes: • Temporary gravel construction entrance • Filter fabric fences (Silt fences) j Ground cover measures such as straw cover and/or hydroseeding f • Inlet protection F ] Vehicle tracking of mud off -site shall be avoided. Installation of a gravel construction 1 entrance will be installed at a location to enter the site. The entrances are a minimum requirement and may be supplemented if tracking of mud onto public streets becomes 1 excessive.

Filter fabric (geotextile) must be placed on top of the drain rock (if proposed to be covered with backfill material) and on the trench sides prior to filling with the drain rock. 6. Spacing between trench centerlines must be at least 6 feet. 7. Infiltration trenches must be setback at least 15 feet from buildings with crawl space or basement elevations that are below the overflow point of the infiltration system. 8. To prevent damage to overlying pavement, trenches located beneath pavement shall be constructed such that the trench pipe is connected to a small yard drain or catch basin with a grate cover so that if the trench infiltration capacity is exceeded, the overflow would occur out of the catch basin at an elevation at least one foot below that of any overlying pavement, and in a location that provides a safe path for the overflow. 9. Runoff from roadways, driveways, and parking areas shall pass through a yard drain or catch basin fitted with a down -turned elbow prior to entering the infiltration trench (see Figure C.2.2.13, p. C-43). The elbow is intended to trap spilled material in the catch basin sump so that the spilled material can I be cleaned up more easily by the homeowner. C.2.2.4 USE OF DRYWELLS FOR FULL INFILTRATION Drywells are gravel filled holes as opposed to trenches and therefore may allow for a more compact design in areas where the depth to the maximum wet -season water table is relatively deep (e.g., 6 feet or greater). Figure C.2.2.0 on page C-44 illustrates the specifications for drywell infiltration systems as outlined below: 1. When located in coarse sands and cobbles, drywells must contain a volume of gravel equal to or greater than 60 cubic feet per 1,000 square feet of impervious surface served. When located in medium sands, drywells must contain at least 90 cubic feet of gravel per 1,000 square feet of impervious surface served. 2. Drywells must be at least 48 inches in diameter and deep enough to contain the gravel amounts specified above for the soil type and impervious surface area served. 3. The gravel used for drywells must be 11/2-inch to 3-inch washed drain rock. The drain rock may be covered with backfill material as shown in Figure C.2.2.0 (p. C-44) or remain exposed at least 6 inches below the lowest surrounding ground surface. 4. Filter fabric (geotextile) must be placed on top of the drain rock (if proposed to be covered with backfill material) and on the drywell sides prior to filling with the drain rock. 5. Spacing between drywells shall be a minimum of 10 feet. 6. Drywells must be setback at least 15 feet from buildings with crawl space or basement elevations that are below the overflow point of the drywell. C.2.2.5 USE OF GROUND SURFACE DEPRESSIONS FOR FULL INFILTRATION Ground surface depressions (also called "infiltration depressions") are another option for full infiltration if the maximum wet -season water table or hardpan is at least 3 feet below the bottom of the depression. Figure C.2.2.13 illustrates the specifications for infiltration depressions as outlined below: 1. When located in coarse sands or cobbles, infiltration depressions must be able to store at least 40 cubic feet of stormwater per 1,000 square feet of impervious surface served. When located in medium sands, ground surface depressions must be able to store at least 60 cubic feet of stormwater per 1,000 square feet of impervious surface served. This volume of water storage must be achieved through the excavation of existing native soil, not through the construction of berms. 2. The stormwater storage areas of infiltration depressions must be at least 12 inches in depth with a minimum 6 inches of freeboard before overflow. 1/24/2005 2005 Surface Water Design Manua] — Appendix C C-40 I SECTION C.2 FLOW CONTROL BMPs 6" 6" 12" 1 /24/2005 FIGURE C.2.2.A TYPICAL TRENCH INFILTRATION SYSTEM roof drain PLAN VIEW NTS 4" rigid or 6" flexible perforated pipe infiltration trench sump wlsolid lid a Ae roof drain overflow _ 4" rigid or 6" flexible splash block F perforated pipe in washed rock ° a ° �Q t�L irs 5.0' min 1 1/2"-3/4" ° °° o °' -------- --------•-.� �_o -�-- --�R finemeshCB sump w/solid lid varies — filter fabric ---% 6" v } °o ❑a O ❑ 24" ° o V ❑ �a a p°Va ❑° ❑ 12" ❑ a o a7 <3 ❑ . 9°da0 ova° SECTION A NTS C-42 — compacted backfill _. 4" rigid or 6" flexible perforated pipe — washed rock 1 1/2"-3/4" 2005 Surface Water Design Manual — Appendix C u Project name: Brad Gehring Residence Project Address: 29929 - Military Road South Federal Way, WA 98003 Date: 14May-08 Designer.

For projects in Small Project Drainage Review, these measures may be used if no more than 3 acres of soil will be disturbed by the project. Other ESC measures may be allowed or required by DDES if these are inappropriate for the project or fail to contain sediment on the project site. A description of other measures and a more detailed description of those included here can be found in the ESC Standards. Projects that disturb 3 acres or more of soil will require an ESC plan developed by a civil engineer under a Targeted Drainage Review. Intent of ESC Measures The intent of ESC measures is to prevent, to the maximum extent practicable, the transport of sediment and other construction -related pollutants to streams, wetlands, lakes, drainage systems, and adjacent properties during and after construction. Erosion of disturbed areas on construction sites can result in excessive sediment transport to adjacent properties and to surface waters. This sediment can result in major adverse impacts, such as flooding due to obstructed drainage ways, smothering of salmonid spawning beds, creation of algal blooms in lakes, and violation of State water quality standards for turbidity. In addition to sediment, other construction -related pollutants can be generated by uncovered waste materials, stockpiles, and demolition debris; de -watering; maintenance and operation of heavy equipment; chemical spills; oil spills; placement of concrete; and application of fertilizers and pesticides. Such pollutants can be toxic to both fish and humans and may violate State water quality standards and the prohibited discharges section of KCC 9.12. Stabilization of the site after construction and prior to the wet season is also important to preventing these impacts. Organization of Section C.3 The ESC measures in this section are divided into two categories, those used during construction and those used after. Those measures used during construction are referred to as temporary ESC measures while those used after construction are referred to as permanent or final stabilization measures. Thus, the section is organized as follows: Section C.3.1, "Temporary ESC" (p. C-79) Section C.3.2, "Final Stabilization" (p. C-90) C.3.1 TEMPORARY ESC Temporary ESC measures are used during construction to minimize the amount of sediment mobilized and trap any mobilized sediment before it leaves the project site. This section presents the requirements and specifications for those temporary ESC measures typically applied to projects in Small Project Drainage Review. They include the following: • "Stabilized Construction Entrance," Section C.3.1.1 (p. C-80) • "Mulching," Section C.3.1.2 (p. C-81) ■ 'Nets and Blankets," Section C.3.1.3 (p. C-83) • 'Plastic Covering," Section C.3.1.4 (p. C-85) • "Mark Clearing Limits/Minimize Clearing," Section C.3.1.5 (p. C-86) • "Silt Fence," Section C.3.1.6 (p. C-86) • "Vegetated Strip," Section C.3.1.7 (p. C-88) 2005 Surface Water Design Manual — Appendix C C-79 1/24/2005 SECTION C.3 EROSION AND SEDIMENT CONTROL (ESC) MEASURES • "Triangular Silt Dike," Section C.3.1.8 (p. C-89) i ■ "Winter Stabilization," Section C.3.1.9 (p. C-90) The above measures must be implemented as needed to prevent the discharge of sediment -laden water I from the construction site. Proposed measures must be shown on the small site ESC plan required to be I submitted with the small project drainage plans. Site -specific conditions during construction may require additional measures as deemed necessary by DDES. As noted in Section C.3 above, other temporary ESC measures found in Appendix D of the SWDM may be needed or may be more appropriate for the project site as determined by DDES. C.3.1.1 STABILIZED CONSTRUCTION ENTRANCE Purpose Construction entrances are stabilized to reduce the amount of sediment transported onto paved roads by motor vehicles or runoff by constructing a stabilized pad of quarry spalls at the entrances to construction sites. Application Construction entrances shall be stabilized wherever traffic will be leaving a construction site and traveling on paved roads or other paved areas within 1,000 feet of the site. Design and Installation Specifications 1. See Figure C.3.1.A for details. 2. A separation geotextile shall be placed under the spalls to prevent fine sediment from pumping up into the rock pad. The geotextile shall meet the following standards: Grab Tensile Strength (ASTM D4751) 200 psi min. Grab Tensile Elongation (ASTM D4632) 30% max. Mullen Burst Strength (ASTM D3786-80a) 400 psi min. AOS (ASTM D4751) 20-45 (U.S. standard sieve size) 3. Hog fuel (wood based mulch) may be substituted for or combined with quarry spalls in areas that will J not be used for permanent roads. The effectiveness of hog fuel is highly variable, but it has been used successfully on many construction sites. It generally requires more maintenance than quarry spalls. Hog fuel is not recommended for entrance stabilization in urban areas. The inspector may at any time require the use of quarry spalls if the hog fuel is not preventing sediment from being tracked onto pavement or if the hog fuel is being carried onto pavement. Hog fuel is prohibited in permanent roadbeds because organics in the subgrade soils cause difficulties with compaction. 4. Whenever possible, the entrance shall be constructed on a firm, compacted subgrade. This can substantially increase the effectiveness of the pad and reduce the need for maintenance. Maintenance J1. Quarry spalls (or hog fuel) shall be added if the pad is no longer in accordance with the specifications. 2. If the entrance is not preventing sediment from being tracked onto pavement, then alternative measures to keep the streets free of sediment shall be used. This may include street sweeping, an Jincrease in the dimensions of the entrance, or the installation of a wheel wash. If washing is used, it 1 1/24/2005 2005 Surface Water Design Manual — Appendix C `JJ C-80 C.3.1 TEMPORARY ESC shall be done on an area covered with crushed rock, and wash water shall drain to a sediment trap or pond. 3. 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: 1. 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:1 V with more than 10 feet of vertical relief. 2005 Surface Water Design Manual — Appendix C 1/24/2005 C-81 SECTION C.3 EROSION AND SEDIMENT CONTROL (ESC) MEASURES Design and Installation Specifications For mulch materials, application rates, and specifications, see Table C.3.1.A. Note: Thicknesses may be increased for disturbed areas in or near critical areas or other areas highly susceptible to erosion. Maintenance Standards 1. 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.

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. 1/24/2005 2005 Surface Water Design Manual — Appendix C C-82 C.3.1 TEMPORARY ESC C.3.1.3 NETS AND BLANKETS Purpose Erosion control nets and blankets are intended to prevent erosion and hold seed and mulch in place on steep slopes and in channels so that vegetation can become well established. In addition, some nets and blankets can be used to permanently reinforce turf to protect drainage ways during high flows. Nets are strands of material woven into an open, but high -tensile strength net (for example, jute matting). Blankets are strands of material that are not tightly woven, but instead form a layer of interlocking fibers, typically held together by a biodegradable or photodegradable netting (for example, excelsior or straw blankets). They generally have lower tensile strength than nets, but cover the ground more completely. Coir (coconut fiber) fabric comes as both nets and blankets. Conditions of Use Erosion control nets and blankets should be used: 1. For permanent stabilization of slopes 2H:1 V or greater and with more than 10 feet of vertical relief. 2. In conjunction with seed for final stabilization of a slope, not for temporary cover. However, they may be used for temporary applications as long as the product is not damaged by repeated handling. In fact, this method of slope protection is superior to plastic sheeting, which generates high -velocity runoff. 3. For drainage ditches and swales (highly recommended). The application of appropriate netting or blanket to drainage ditches and swales can protect bare soil from channelized runoff while vegetation is established. Nets and blankets also can capture a great deal of sediment due to their open, porous structure. Synthetic nets and blankets may be used to permanently stabilize channels and may provide a cost-effective, environmentally preferable alternative to riprap. Design and Installation Specifications 1. See Figure C.3. LB and Figure C.3.1.0 for typical orientation and installation of nettings and blankets. Note: Installation is critical to the effectiveness of these products. If good ground contact is not achieved, runoff can concentrate under the product, resulting in significant erosion. 2. Jute matting must be used in conjunction with mulch. Excelsior, woven straw blankets, and coir (coconut fiber) blankets may be installed without mulch. There are many other types of erosion control nets and blankets on the market that may be appropriate in certain circumstances. Other types of products will have to be evaluated individually. In general, most nets (e.g., jute matting) require mulch in order to prevent erosion because they have a fairly open structure. Blankets typically do not require mulch because they usually provide complete protection of the surface. 3. Purely synthetic blankets are allowed but shall only be used for long-term stabilization of waterways. The organic blankets authorized above are better for slope protection and short-term waterway protection because they retain moisture and provide organic matter to the soil, substantially improving the speed and success of re -vegetation. Maintenance Standards 1. Good contact with the ground must be maintained, and there must not be erosion beneath the net or blanket. 2. Any areas of the net or blanket that are damaged or not in close contact with the ground shall be repaired and stapled. 3.

Conditions of Use 1. Plastic covering may be used on disturbed areas that require cover measures for less than 30 days. 2. Plastic is particularly useful for protecting cut and fill slopes and stockpiles. Note: The relatively rapid breakdown of most polyethylene sheeting makes it unsuitable for long-term applications. 3. Clear plastic sheeting may be used over newly -seeded areas to create a greenhouse effect and encourage grass growth. Clear plastic should not be used for this purpose during the summer months because the resulting high temperatures can kill the grass. 4. Due to rapid runoff caused by plastic sheeting, this method shall not be used upslope of areas that might be adversely impacted by concentrated runoff. Such areas include steep and/or unstable slopes. Note: There have been many problems with plastic, usually attributable to poor installation and maintenance. However, the material itself can cause problems, even when correctly installed and maintained, because it generates high -velocity runoff and breaks down quickly due to ultraviolet radiation. In addition, if the plastic is not completely removed, it can clog drainage system inlets and outlets. It is highly recommended that alternatives to plastic sheeting be used whenever possible and that its use be limited. Design and Installation Specifications 1. See Figure C.3.1.D for details. 2. Plastic sheeting shall have a minimum thickness of 0.06 millimeters. 3. If erosion at the toe of a slope is likely, a gravel berm, riprap, or other suitable protection shall be installed at the toe of the slope in order to reduce the velocity of runoff.

Torn sheets must be replaced and open seams repaired. 2. If the plastic begins to deteriorate due to ultraviolet radiation, it must be completely removed and replaced. C.3.1.5 MARK CLEARING LIMITS/MINIMIZE CLEARING 1 Purpose { Minimizing clearing is the most effective method of erosion control. Undisturbed vegetation intercepts and slows rainwater. Plant roots hold soil in place, and dead vegetation on the ground acts as a mulch. Applications Clearing limits shall be marked and clearing minimized on any site where significant areas of undisturbed vegetation will be retained. Design Specifications Minimizing clearing should be incorporated into the site design. Clearing limits must be marked on the small site ESC plan. On the ground, clearing limits must be clearly marked with brightly colored tape or plastic or metal safety fencing. If tape is used, it should be supported by vegetation or stakes, and should be about 3 to 6 feet high and highly visible. Equipment operators should be informed of areas of vegetation that are to be left undisturbed. Maintenance Fencing shall be inspected regularly and repaired or replaced as needed. C.3.1.6 SILT FENCE j J- j I j j1/24/2005 Purpose Use of a silt fence reduces the transport of coarse sediment from a construction site by providing a temporary physical barrier to sediment and reducing the runoff velocities of overland flow. Conditions of Use Silt fence may be used downslope of all disturbed areas. Silt fence is not intended to treat concentrated flows, nor is it intended to treat substantial amounts of overland flow. Design and Installation Specifications 1. See Figure C.3.1.E and Figure C.3.11 for details. 2. The geotextile used must meet the standards listed below. A copy of the manufacturer's fabric specifications must be available onsite. AOS (ASTM D4751) 30-100 sieve size (0.60-0.15 mm) for slit film 50-100 sieve size (0.30-0.15 mm) for other fabrics Water Permittivity (ASTM D4491) 0.02 sec-1 minimum Grab Tensile Strength (ASTM D4632) 180 lbs. min. for extra strength fabric 100 lbs. min. for standard strength fabric Grab Tensile Elongation (ASTM D4632) 30% max. Ultraviolet Resistance (ASTM D4355) 70%m1n. C-86 2005 Surface Water Design Manual — Appendix C 11 C.3.1 TEMPORARY ESC R I j 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:IV. 5. If a typical silt fence (per Figure C.3. LE) 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 1. 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 important 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. 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 4 1. 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:1 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). J 1/24/2005 2005 Surface Water Design Manual — Appendix C _ j C-88 a� C.3.1 TEMPORARY ESC Maintenance Standards 1. Any areas damaged by erosion or construction activity shall be seeded immediately and protected by mulch. 2. If more than 5 feet of the original vegetated strip width has had vegetation removed or is being eroded, sod must be installed. C.3.1.8 TRIANGULAR SILT DIKE Purpose Triangular silt dikes (TSDs) may be used as check dams, for perimeter protection, for temporary soil stockpile protection, for drop inlet protection, or as a temporary interceptor dike. Silt dikes, if attached to impervious surfaces with tack or other adhesive agent may also be used as temporary wheel wash areas, or concrete washout collection areas. Conditions of Use 1. May be used for temporary check dams in ditches. 2. May be used on soil or pavement with adhesive or staples. 3. TSDs have been used to build temporary sediment ponds, diversion ditches, concrete washout facilities, curbing, water bars, level spreaders, and berms. Design and Installation Specifications 1. TSDs must be made of urethane foam sewn into a woven geosynthetic fabric. 2. TSDs are triangular, 10 inches to 14 inches high in the center, with a 20-inch to 28-inch base. A 2- foot apron extends beyond both sides of the triangle along its standard section of 7 feet. A sleeve at one end allows attachment of additional sections as needed 3. Install TSDs with ends curved up to prevent water from flowing around the ends 4. Attach the TSDs and their fabric flaps to the ground with wire staples. Wire staples must be No. 11 gauge wire or stronger and shall be 200 mm to 300 min in length. 5. When multiple units are installed, the sleeve of fabric at the end of the unit shall overlap the abutting unit and be stapled. 6. TSDs must be located and installed as soon as construction will allow. 7. TSDs must be placed perpendicular to the flow of water. 8. When used as check dams, the leading edge must be secured with rocks, sandbags, or a small key slot and staples. 9. When used in grass -lined ditches and swales, the TSD check dams and accumulated sediment shall be removed when the grass has matured sufficiently to protect the ditch or swale unless the slope of the swale is greater than 4 percent. The area beneath the TSD check dams shall be seeded and mulched immediately after dam removal. Maintenance Standards 1. Triangular silt dikes shall be monitored for performance and sediment accumulation during and after each runoff producing rainfall event. Sediment shall be removed when it reaches one half the height of the silt dike. 2. Anticipate submergence and deposition above the triangular silt dike and erosion from high flows around the edges of the dike/dam. Immediately repair any damage or any undercutting of the dike/dam. 2005 Surface Water Design Manual — Appendix C I C-89 1/24/2005 SECTION C.3 EROSION AND SEDIMENT CONTROL (ESC) MEASURES C.3.1.9 WINTER STABILIZATION Purpose In order to minimize sediment -laden runoff, as much of the bare and disturbed portions of the project site as possible should be covered during any period of precipitation. Once sediment is mobilized, it is much more difficult to effectively control. Application All project sites require winter stabilization between October 1 and April 30 (the wet season). Design Specifications During the above time frame, slopes and stockpiles 3H:1 V or steeper and with more than 10 feet of vertical rise shall be covered if they are to remain unworked for more than 12 hours. Other disturbed areas shall be covered or mulched according to Table C.3. LA (p. C-82) if they are to remain unworked for more than two days. Cover material sufficient to cover all disturbed areas shall be stockpiled on the site at the beginning of the wet season. Areas that are to be left unworked during the winter shall be seeded prior to September 23. Maintenance The project site should be inspected weekly and immediately before, during, and after storms. Cover and other erosion control measures shall be repaired and enhanced as necessary to prevent or minimize sediment runoff and transport. C.3.2 FINAL STABILIZATION Purpose Final stabilization minimizes sediment -laden runoff from the project site after construction has been completed. Application All sites require final stabilization prior to final construction approval. Design Specifications Prior to final construction approval, the project site shall be stabilized to prevent sediment -laden water from leaving the project site after project completion. All disturbed areas of the project site shall be vegetated or otherwise permanently stabilized. At a minimum, disturbed areas must be seeded and mulched to ensure that sufficient cover will develop shortly after final approval. Mulch without seeding is adequate for small areas to be landscaped before October 1. All permanent surface water facilities (including catch basins, manholes, pipes, ditches, channels, flow control facilities, and water quality facilities) impacted by sedimentation during construction must be cleaned. Maintenance Permanent erosion control is the responsibility of the owner. The project site must be kept stabilized using landscaping, mulch, or other measures to prevent sediment -laden water from leaving the project site and to prevent sediment from being transported onto adjacent properties and roads. 2005 Surface Water Design Manual — Appendix C C-90 Gehring Short Plat - Preliminary TIR May 2008 Appendix F Maintenance Procedures The Concept Group Appendices APPENDIX A MAINTENANCE REQUIREMENTS FOR FLOW CONTROL, CONVEYANCE, AND WQ FACILITIES � NO.2 - INFILTRATION FACILITIES Maintenance Defect or Problem Conditions When Maintenance Is Needed Component Infiltration Pond Trash & Debris See "Detention Ponds" Table No. 1 General Infiltration Pond Side Slopes Infiltration Pond Emergency Overflow Spillway and Berms over 4 feet in height.
