"City storm water system"means the portions of the storm water system in public rights-of-way, within easements in favor of the City, or on City property.
"Equivalent dwelling unit" ("EDU")means a configuration of development or impervious surface estimated to contribute an amount of runoff to the City's storm water system that is approximately equal to that created by the average developed single-family residence. One EDU is equal to 2,500 square feet of impervious surface area. All single-family residences will be deemed to be one EDU, regardless of impervious surface area.
"Impervious surface"means an artificially created hard-surfaced area that either prevents or retards the entry of water into the soil mantle and/or causes water to run off the surface in greater quantities or at an increased rate of flow from that present under natural conditions. Impervious surfaces may include, but are not limited to, rooftops, concrete or asphalt paving, walkways, patios, driveways, parking lots or storage areas, trafficked gravel, and oiled, macadam or other surfaces which similarly impede the natural infiltration or runoff of storm water. However, not all driveways or concrete are impervious, and the Public Works Director will determine whether a particular surface is impervious.
"Improved premises"means any area that the Public Works Director determines has been altered such that the runoff from the site is greater than that which could historically have been expected. "Improved premises" do not include public roads under the jurisdiction of the City, County, State, or Federal government.
"Person responsible"means the occupant, lessee, tenant, contract purchaser, owner, agent or other person having possession of property, or if no person is in possession, then the person in control of the use of the property, or in control of the supervision of development on the property.
"Storm water"means water from precipitation, surface, or subterranean water from any source, drainage, and non-septic wastewater.
"Storm water service"means the operations of the City's storm water system in providing programs and facilities for maintaining, improving, regulating, collecting, and managing storm water quantity and quality within the City's service area.
"Storm water system"means any structure or configuration of ground that is used or by its location becomes a place where storm water flows or is accumulated, including, but not limited to, pipes, sewers, curbs, gutters, manholes, catch basins, ponds, creeks, open drainageways, ditches and their appurtenances.
