C-2 r BELFAIR HUB WNEK ENGINEERING Drainage Analysis February 12, 2014 3. OVERVIEW The purpose of this report is to provide storm mitigation for the development. The project is a two story commercial building on a parcel. Road access from Old Belfair Hwy NE will be established to serve the building. The site contains a wetland and steep slope on the western portion of the parcel. The critical areas will remain in a dedicated native vegetation buffer. The project basin is an undeveloped lot with native vegetation and shrubs. The proposed development will clear the eastern portion of the lot and create a commercial building as well as porous pavement parking areas to serve that building. The stormwater from the building roof will be routed to the porous pavement parking lot. Flow control criteria is met through infiltration. Stormwater treatment is met through infiltration of >91% of runoff. The porous pavement will be parking over a shallow gravel bed in the hydrology calculations in order to correctly model the flow of water through subsurface storage spaces provided by the paving system. The porous pavement design will be separated into three areas reflecting the proposed grades and low points where the water will naturally flow. Each area will have a perforated pipe and catch basin connected to a main stormwater pipe running to the downstream outlet; this outlet will discharge the remaining 0.03% of the stormwater and provide an emergency overflow. Each of the three areas will receive 1/3 of the building downspout runoff. The system will allow emergency overflows to flow down the perforated pipe in each basin before surface water is evident in the porous pavement. At maximum capacity, the 4" perforated pipe flows 85% full, providing a freeboard of 7 inches between the crown of the 4" perforated pipe and the surface of the porous pavement. The overflows will be routed to the western discharge point which has a shallow pipe slope to ensure low flow velocities during all flow periods. 4. MINIMUM TECHNICAL REQUIREMENTS (MR) REVIEW a. MR#1, Preparation of Stormwater Site Plans A stormwater site plan will be provided for the project. b. MR#2, Construction Stormwater Pollution Prevention (SWPP) A SWPP plan will be provided for the project. c. MR#3, Source Control of Pollution There are no source controls warranted for the construction. d. MR#4, Preservation of Natural Drainage Systems and Outfalls Stormwater overflows will be discharged to the west, however the majority of the project runoff infiltrates in-place. D-1 l � BELFAIR HUB WNEK ENGINEERING Drainage Analysis February 12, 2014 e. MR#5, On-Site Stormwater Management Stormwater management techniques proposed: Stormwater will be infiltrated on this site in the porous pavement areas. f. MR#6, Runoff Treatment All areas will be treated through infiltration in the porous pavement areas. g. MR#7, Flow Control Flow control for all areas will be met by infiltration in the porous parking area. h. MR#8, Wetlands Protection The wetlands delineated in the western portion of the parcel is protected by a dedicated native vegetation buffer as shown on the site plan. i. MR#9, Operations and Maintenance A Stormwater O&M Manual for the project will be provided after completion of construction. 5. WATERSHED DESCRIPTION a. Contributing Basin The basin consists of the slopes and surfaces on the parcel being developed. There is no off-site drainage added to the basin. b. Receiving Waters Adequate Receiving Body No Downstream Enclosed Sewer or Manmade Channel No Stream or Wetland Yes c. Watershed Description The project is in the Union River watershed. 6. DESCRIPTION OF UPSTREAM BASINS a. Sources of Runoff Onto Project Site Minimal. See Section 2.e. 'Existing Conditions, Offsite Drainage Onto Property' b. Existing Drainage & Erosion Problems No obvious drainage/erosion problems within the upstream basin. D-2 BELFAIR HUB WNEK ENGINEERING Drainage Analysis February 12, 2014 7. DOWNSTREAM ANALYSIS (Level 1) a. Basin Limits (Logical subsets of watershed) See Section E exhibits. Area Basin - Upstream and project basin. Project Basin —The project basin is defined by the area of project development. Upstream Basin — Minimal, included in Area Basin. Downstream Basin — Union River, Hood Canal. b. Resource Information Aerial photo (Google Earth Pro) and USGS topography. Mason County GIS Department c. Field Inspection A general field inspection & inventory of the downstream route was performed on August 23, 2013. The project area in parcel 12329-13-90042 flows either east to an existing ditch system along Old Belfair Hwy NE and subsequently west through an 18" culvert which discharges to slopes leading to the Union River, or west to the Union River. Further inspection was not performed in the field. Google Earth and USGS topographic maps were used to evaluate that the culvert discharge flows to the Union River. The Union River flows generally southwest to the Hood Canal. d. Area Basin Map See exhibit: SITE & BASIN PLAN, Section E. e. Area Basin Characteristics Native vegetation and lawn/landscape. f. Structures & Channel All streets in the vicinity are served by roadside ditches which lead to the Union River. g. Problem Areas None. h. Summary No obvious erosion or capacity problems were observed in the downstream routes. 8. SOILS REPORT Soils data included. 9.

Methodology The "Western Washington Hydrology Model" (Continuous Simulation) is used for analysis of recharge, flow control and treatment using WWHM4 software. b. References WWHM4 Software, Version 2013111120, Clear Creek Solutions, Inc. Stormwater Management Manual for Western Washington, February 2005 Low Impact Development, Puget Sound Action Team, January 2005 Mason County Code 17.80.010 Low Impact Development(LID) c. Soils The existing soils consist of a layer of topsoil underlain by medium to medium dense silty sand. Results of the soil samples are included in the Geotechnical Report. Infiltration is modeled at a rate of 2 in/hr and a safety factor of 4. This rate is very conservative. Porous pavement provides the advantage of infiltrating over a wide area; full scale in-situ infiltration testing is not warranted. The soils were tested for Cation Exchange Capacity (CEC), a result of 7.82 was determined; therefore the existing native soils are adequate for providing stormwater treatment (CEC 7 5). d. Hydrology Calculations are provided from WWHM4 to show flow control / water quality criteria for the parcel. e. Hydraulic Volumes of storm runoff discharged to the western portion of the parcel will be less than the volumes prior to the proposed project due to infiltration of the porous pavement system. 8" diameter piping is adequate to convey the entire project. f. Flow Control Flow control criteria is met by infiltration in the parking area. g. Dispersion No dispersion will be done. h. Treatment Treatment requirements for the PGIS are met by infiltration. D-4 • BELFAIR HUB WNEK ENGINEERING Drainage Analysis February 12, 2014 i. Overflow The perforated pipes and catch basins provide overflow capacity to the proposed discharge point. 12. EROSION & SEDIMENTATION CONTROL This section describes the temporary erosion control features to be used during construction. For permanent water quality features, see Section 11 of this report. a. Erosion Control Objectives To prevent sediments, and sediment laden runoff, from leaving the site. b. Erosion Control /Temporary Water Quality Facilities The following temporary erosion control facilities will be used for the project: Filter Fabric Fence, sediment Traps. c. Revegetation Plan The wetland will be enhanced per the projects Habitat Mgt. Plan. Areas not specifically designated for gravel or pavement will be landscaped. d. Soil Stability In general, no slopes steeper than 2:1 will be required for the project. Where slopes steeper than 2:1 are necessary, retaining walls will be used. Retaining walls over 4 feet in height require a building permit from Mason County. e. Computations for Conveyance The types of erosion control facilities proposed for this project do not require any engineering calculations. f. Computations for Sediment Containment The types of erosion control facilities proposed for this project do not require any engineering calculations.

Factor K is one of six factors used in the Universal Soil Loss Equation(USLE) and the Revised Universal Soil Loss Equation (RUSLE) to predict the average annual rate of soil loss by sheet and rill erosion in tons per acre per year. The estimates are based primarily on percentage of silt, sand, and organic matter and on soil structure and saturated hydraulic conductivity(Ksat).Values of K range from 0.02 to 0.69. Other factors being equal, the higher the value, the more susceptible the soil is to sheet and rill erosion by water. "Erosion factor Kw (whole soil)" indicates the erodibility of the whole soil. The estimates are modified by the presence of rock fragments.
