1.0 PROJECT OVERVIEW
The project is located in the City of Federal Way at 35XXX 6th Avenue SW, Federal Way, WA on tax parcel
number3021049155. Mores pecifica I ly, the project is located in Section 31, Township 21 North, Range
4 East, Willamette Meridian, King County, Washington. The project proposes subdivide the existing
parcels into 2 total lots. An area table has been provided below in this section. The 0.73 -acre property
is bound by single-family residences to the north and east with SW 366th Street to the south and
6thAveue SW to the west. The existing topography varies from approximately 0 to 40 percent and the
site generally falls from northwest to southeast. The vegetation on the project site consists of existing
forest with some pasture. In the existing condition, runoff from the project area sheet flows to the
southeast to the existing storm system in SW 366th Street. Runoff in the developed condition will be
handled through the use of infiltration to the maximum extentfeasible. Where infiltration is infeasible,
dispersion will be utilized.
There are no known critical areas on the subject property.

4.0 FLOW CONTROL, LOW IMPACT DEVELOPMENT (LID) AND WATER QUALITY FACILITY ANALYSIS AND
DESIGN
A. Existing Site Hydrology
The existing project area consists of an existing forest with some pasture. On -site soils consist of
Alderwood till soils according to the NRCS soil survey. Runoff in the existing condition sheet flows to the
southeast. An area summary of the predeveloped condition has been included in section 1.0.
B. Developed Site Hydrology
The developed site consists of 2 new single-family residences and associated driveway and landscaping.
The site is currently forest with some pasture. Stormwater runoff from the proposed surfaces will be
handled through a combination of dispersion and infiltration if possible. Infiltration is feasible for
shallow systems with testing and/or comparison of the original soil testing during the building permit
phase with site layouts determined. Infiltration is proposed to the maximum extent feasible in
accordance with the septic/soils recommendations of utilizing sandy loam as determined in the field.
The driveways will utilize permeable pavement. WWHM calculations have been prepared to
demonstrate that up to 3,000 SF of rooftop could be dispersed and still meet the flow control standards
such that a detention system would not be required.
C. Performance Standards
The project is located within the City of Federal Way. The project site lies within the Level 2 flow control
standards. The project does not exceed the thresholds requiring a flow control facility. The project is
resulting in an increase of less than 0.15 cfs in the developed condition above the existing predeveloped
condition. Calculations have been completed to demonstrate that up to 3,000 SF of rooftop per lot
could be dispersed and still meet the flow control standards such that a detention system would not be
required. See calculations in Appendix B. As a part of the Flow Control BMPs and minimum
requirement#9, the proposed project is choosing the list approach for minimum requirement#9. The
BMP Requirements have been summarized below for feasibility:
Full Dispersion: This BMP is infeasible due to lack of available flow path and native vegetation.
Full Infiltration: This BMP is infeasible as the site does not contain outwash soils and does not meet
groundwater indicator separation requirements.
Limited Infiltration: This BMP is feasible and will be utilized to the maximum extentfeasible through
infiltration trenches sized for 21 lineal feet oftrench per 1,000 square foot of tributary area.
Bioretention: This BMP is not applicable as limited infiltration is proposed.
Permeable Pavement:This BMP is feasible and will be utilized forthis project.
Basic Dispersion: This BMP is feasible for portions of the development and will be utilized where
infiltration is infeasible.
Soil Amendment: All disturbed soils will be amended in accordance with the City of Federal Way and
KCSWDM requirements.
Perforated Pipe Connection: Not applicable.
D. Flow Control System
The proposed project will utilize a combination of infiltration and dispersion to handle runoff in
accordance with the performance standards identified above. The driveways will be handled by
infiltration or sheetf low dispersion. The proposed rooftops will be handled via infiltration or dispersion
where infiltration is infeasible.
E. Water Quality System
Water quality is not required forthis project as the pollution generating impervious surface is less than
5,000 square feet.

6.0 SPECIAL REPORTS AND STUDIES
Soils Report: Soils testing was completed by Westside Septic dated December 10, 2018. The report has
been included in Appendix A.
7.0 OTHER PERMITS
Other permits necessary forth is project include:
• ROW permit
8.0 CSWPP ANALYSIS AND DESIGN
The site will utilize Appendix D of the 2021 KCSWDM and the standard design details from the 2019
Stormwater Management Manual for Western Washington for the erosion and sedimentation control
design. Refer tothe approved TESC plan. Below is a breakdown of how each require element is
addressed:
1. Clearing Limits
Clearing limits will be established in the field. Clearing limits will be clearly marked forfenced.
2. Cover Measures
Disturbed areas will be covered through temporary or permanent means. Any soils unworked for more
than 7 days during the dry season (May 1 to September 30) or 2 days during the wet season (October 1
to April 30) will have erosion control nets/blankets, plastic sheeting and temporary or permanent
seeding.
3. Perimeter Protection
Perimeter protection is proposed forthe downslope areas as shown on the approved plans. Perimeter
protection shall be used in the form of silt fence.
4. Traffic Area Stabilization
A temporary construction entrance is proposed atthe entryto the site.
5. Sediment Retention
Sediment retention is proposed in the form of catch basin inlet protection as downstream catch basins
from the subject project area.
6. Surface Water Collection
Surface waterwill be intercepted bythe silt fence. Any runoff that leaves the proposed site will be
intercepted in downstream storm drainage systems.
7. Dewatering Controls
No dewatering is anticipated as a part of this project.
8. Dust Control
Dust control will be achieved by watering any exposed soils.
9. Flow Control
Additional flow control measures are not required as part of this project.
10. Control Pollutants
The only anticipated potential source of pollutants associated with the projectwould be from mobile
fueling of construction equipment as necessary. If necessary, mobile fueling shall be done in accordance
with BMP A-48 from the 2021 King County Stormwater Pollution Prevention Manual.
11. Protect Existing and Proposed Flow Control BM Ps
Thereare noexistingor proposed BMPs on or immediately downstream of the project site. The
perimeter protection measures along with catch basin inlet protection will aid in the protection of any
downstream storm drainage systems.
12. Maintain BMPs
All BMPs will be maintained and repaired in accordance with BMP specifications.
13. Manage the Project
The projectwill be managed to ensure that all applicable and installed BMPs are adequately maintained
and functioning. In addition, any necessary modifications or repairsto the erosion control BMPs will be
done immediatelyto avoid impact to downstream properties and storm systems.
9.0 BOND QUANTITIES, FACILITY SUMMARIES, AND DECLARATION OF COVENANT
Maintenance covenants will be prepared, reviewed, and recorded priorto plan approval if required.
All bond quantityforms and required bonds will be secured priorto permit issuance.
10.0 OPERATIONS AND MAINTENANCE MANUAL
A separate maintenance exhibit will be prepared fore ach of the single family residences at the time of
building permit if required.

Project Description
Septic Feasibility for 3 bedroom (450 gpd) single family residence septic system meeting
King County Health Standards
King County Parcel # 302104-9154 (east property) and 302104-9155 (west property)

Acres - 0.74 acres (32,184 sq ft) and 0.83 acres (36,070 sq ft)
Water — Proposed public, no water availability letter at this time
Critical Areas — May impact proposed site
Dear Mike,
As per your request, on 12-06-18 sixteen test holes were dug over the two parcels. The soils and site conditions were evaluated in
regards to an on -site septic system on the above referenced property to determine the feasibility of obtaining an approved septic
design from King County Health Department. The soil log descriptions are below. As the properties are under 5 acres, King County
Health requires a minimum of 18" of permeable soil above the High Winter Water Table. The site is slightly sloping downward
(+/- 7') from the west portion of the property to the east portion of the property.
Based upon my site observations and soil logs I believe that the east property can achieve a pre-treatment shallow pressure or
shallow pressure system without having to go through a High Winter Water Review process. In my opinion, the West lot will have
to go through a High Winter Water Review process prior to proceeding with a septic design.
This letter is based upon the King County Health Code (Title 13) and my understanding of the requirements thereof.
If you require any further information, please do not hesitate to ask. Thank you.
Si�}cerely,
