Various flood control, drainage works and storm water systems that include but are not limited to inlets, conduits, manholes, energy dissipation structures, channels, outlets, retention basins, detention basins, other structural components, ditches, floodwalls, basins, pipes, walls, channels, creeks, ponds, drainage easements, drainage rights-of-way, drainage dedications, and other interests in property used, dedicated, controlled, possessed, maintained or leased by the City, for drainage purposes, together with all appurtenances which connect or assist in drainage of water or flood control.
   "IMPERVIOUS SURFACE." Those hard surface areas either which prevent or retard the entry of water into the soil in the manner that the water entered the soil under natural conditions pre-existent to development, or which cause water to run off the surface in greater quantities or at an increased rate of flow than that present under natural conditions pre-existent to development, including, without limitation, the surfaces as roof tops, asphalt or concrete paving, driveways, and parking lots, walkways, patio areas, storage areas, or other surfaces which similarly affect the natural infiltration or runoff patterns existing prior to development.
   "PREMISES." A lot or parcel, and the building and other improvements situated thereon.
