5.0 Stormwater System The stormwater SDC is based upon impervious surface area (e.g., rooftops, driveways, sidewalks, parking lots, patios, and other non-porous surfaces). The detailed formulas for calculating the stormwater SDC unit cost (rate) per square foot of impervious surface area is set forth in Appendix D. The stormwater SDC is determined by multiplying the applicable rate by the unit of measure for the proposed development type. The costs per unit of measure and resulting rates can be found in Table 12 and the fee schedule in Appendix F. Where the stormwater SDC is a fixed amount per dwelling unit or space, it shall be determined by multiplying the applicable rate per dwelling unit or space times the number of units or spaces plus, for manufactured home park development, the. SDC . is based upon the impervious surface area of all additional common areas times the stormwater unit cost per square foot of impervious surface area. Where the stormwater SDC is not a fixed amount per dwelling unit or space, it shall be determined by multiplying the rate per square foot of impervious surface area times the total impervious surface area of the proposed development. Where a development creates impact not attributable to impervious surface area, the stormwater SDC shall be determined by evaluating equivalent impervious surface area, multiplied by the rate per square foot of impervious surface area.
