Measurement: the unit of system capacity. used to determine the relative effect of a new <br />development on the capacity of a specific system. For example, plumbing fixture units are used to <br />determine the effect of development on the {sa~tttary-sewe~j wastewater system. <br />Impervious Surface: used as an impact measure for the .{:~i~r-m-se+^~erj starmwater SDG. An <br />impervious surface is that which prevents or retards saturation of water into the surface of the soil <br />or causes water to run off the surface in greater quantity. or an increased rate of flow compared to <br />the natural condition. of the property before development. Asphalt, concrete, and roofing materials <br />are examples of impervious materials. <br />Improvement Fee: the portion of the system-specific SDC charged to coveran equitable share of <br />-the capital improvements required to increase capacity of the system to accommodate new <br />development.. <br />Level of Service:,, (per unit of development) - as used in development of SDC rates, represents. the <br />amount of system (orsub-system) capacity provided at a certain point in time.
