The size determines whether a Stormwater Site Plan is required in conjunction with a stand-alone stormwater management permit application, building permit application, or other land use approval application that involves stormwater review. The basic information will also be helpful for completing a Stormwater Site Plan, if req PARCEL SIZE (I.E., SITIE) Size of parcel 5 acres An acre contains 43,560 square feet. Multiply the acreage by this figure. Size of parcel in square feet " 1 5 sq/ft Land -disturbing activity is any activity that results in movement of earth, or a change in the existing soil cover (both vegetative and non -vegetative) and/or the existing soil topography. Land disturbing activities include, but are not limited to clearing, grading, filling, excavation, and compaction associated with stabilization of structures and road construction. Native vegetation is vegetation comprised of plant species, other than noxious weeds, which reasonably could have been expected to naturally occur on the site. Examples include species such as Douglas fir, western hemlock, western red cedar, alder, big -leaf maple, and vine maple; shrubs such as willow, elderberry, salmonberry, and salal; herbaceous plants such as sword fern, foam flower, and fireweed.

This document is required to be kept by the contractor performing the work at the jobsite for reference and update during the life of the project. Construction BMP's must be indicated on the stormwater site plan. REFERENCE 61A includes diagrams of common BIVIP's that may be used on the site plan. My completed SWPPP (WORKSHEET 61 or equivalent) is included in this application packet! Minimum Requirement # 3 : Source Control of Pollution (not construction related) The intent of source control is to prevent stormwater from coming in contact with pollutants. Source control BMPs can be operational or structural in nature. A roof over a material storage area is an example of a structural source control BMP. Washing your vehicle on the lawn rather than in the street is an operational BMP. This requirement is generally not applicable to Single Family Residences (SFRs); however, ways to minimize pollution from moving downstream should be considered during the design phase of every project. Specifications on standard source control BMPs that are applicable to various commercial and industrial -type facilities can be found in Volume IV of the 2014 Stormwater Management Manual for Western Washington (SWMMWW) (continued on page 2). page 1 of 6 Worksheet Al -- . Medium & Large Project Report �.s•� f t � �:� i` Minimum Requirement # 3 : Source Control of Pollution (continued from page 1) Check one of the following boxes that best represents your project with regards to MR #3. My project is a Single Family Residence (SFR) and after considering operational and structural measures to prevent stormwater from coming in contact with pollutants, I have: ❑ determined this MR to not be applicable. ❑ made appropriate adjustments to my project. El My project is not a SFR and after reviewing Vol. IV of the SWMMWW, I have determined that this MR is not applicable because of the following reason: ❑ My project is not a SFR and after reviewing Vol. IV of the SWMMWW, I have determined that the following source control BMPs are applicable to my project and shall be incorporated into the project design and operation. page 2 of 6 ;-k)N {•� Worksheet Al .--- _ Medium & large Project Report 1'S•1I1 \Lid Minimum Requirement # 4 : Preservation of Natural Drainage Systems Creating new drainage patterns results in more site disturbance and more potential for erosion and sedimentation during and after construction. to the maximum extent possible, proponents must 1) maintain the natural on -site drainage pattern and concentrated discharge location at the downstream property boundary, and 2) prevent erosion at and downstream of the discharge location. NOTE: All outfalls require energy dissipation. See Table 4.5.1 in Vol. V of the SWMMWW for minimum design standards for rock protection at outfalls. Choose the option below that best describes your project: The project site does not currently have any intermittent, seasonal, or continuous concentrated water moving across any part of the property and the proposed improvements to the site will not create new concentrated flow paths or not discharging to existing drainage systems. The project site has existing concentrated flow drainage systems and outfalls. (NOTE: These items must be graphically shown on the Site Plan or equivalent, to include: type, slope, dimensions, channel lining, direction of flow, buffer, etc.) Select below how it will be addressed. This project will not alter the existing drainage system in any way. If the existing outfall(s) show signs of erosion and scour, energy dissipation measures will be installed or improved upon. Construction activity of any kind will not occur within at least 10 ft. of the edge of the channelized flow. BMP C102: BUFFER ZONES will be implemented during the life of the project to include visible flagging or other demarcation technique. The existing concentrated drainage system traversing the property will be impacted as part of this project, as described in the space below and shown on the site plans. Engineering calculations are required that show the altered drainage design can accommodate the existing flows and the added runoff contributed by the project. page 3 of 6 Worksheet Al Medium & Large Project Report ���'�rl�cs��, Minimum Requirement # 5 : On -site Stormwater Management On -site stormwater management techniques shall be implemented where possible to accommodate the permanently added stormwater runoff being generated by development. Some on -site stormwater management techniques provide better stormwater detention and treatment than others; however, they are not always appropriate for use due to varying individual site characteristics. Therefore, techniques are presented to applicants on the next pages in a hierarchical order and shall be considered for use in the order listed. The first technique on the list that is determined to be possible shall be implemented. See WORKSHEET C to determine which techniques are feasible. Runoff from developments occurring in drainage basins that drain directly or indirectly to a creek require a higher level of stormwater management, thus, the techniques are presented in three lists below: All properties will be in one of these three categories: ❑My project is located in a drainage subbasin that My Project will discharge to a subasin draining to drains to directly or indirectly to freshwater. salt water, Dosewallips River, or Hoh River.
