In Column 1, enter the square footage of impervious area that each facility will manage, 4. Multiply each impervious area from Column 1 by the corresponding sizing I factor in Column 2, and enter the result in Column 3. This is the facility surface area needed to manage runoff from the impervious area. 5. Total Column 1 (Rows 1.12) and enter the resulting "Impervious Area Managed" in Box 2. 6. Subtract Box 2 from Box 1 and enter the result in Box 3. If this number is less than 500 square feet, stormwater quality and quantity requirements have been met. ,Submit this form with the application for permit. , 7.

'i Simolified AODroach Desilm Criteria: GrassV Swale General Description:,Grassy swales are long narrow facilities integrated into site landscaping. Swales are planted with a dense grass mix. Flow through the grass slows the water and facilitates sedimentation and infiltration. General Specifications: Sites with more than 15,000 square. feet of impervious development footprint area call1lot use Form SIM simplified sizing forgrassy swales. For these larger projects, the design criteria presented in Chapter 3.0: Alternative Methods for Stormwater Management shall be used, and additional facilities may be required to meet flow.control requirements. Acceptable for all soil types. All swales will require additional means for disposal. Maximum swale slope is 5%, while minimum slope is I %. Swales using these design criteria will not need to include a bypass of larger storms. Required setback from property lines is 5 feet. Checklist of minimal information to be shown on the permit drawings: (Additional information may be required on the drawings during permit review, depending on individual site conditions.) 1) Facility dimensions and setbacks from property lines and structures 2) Profile view of facility, including typical cross.sections with dimensions 3) Growing medium specification 4) Impermeable fabric specification (if applicable) 5) Filter fabric specification 6) All stormwater piping associated with the facility, induding pipe materials, sizes, slopes, and invert elevations at every' bend or connection 7) Landscaping plan (See Chapter 5.0) Landscaping requirements: See Chapter 5.0. * Liuk to facility-specific planting requirements Inspection requirements and schedule: The following table shall be used to determine which stormwater facility components require City inspection, and when the inspection shall be requested: : .
