Runoff coefficient means the fraction of total rainfall that will appear at the conveyance as runoff.
Stormwater means water resulting from precipitation (including rain and snow) that runs off the land’s surface, is transmitted to the subsurface, or is captured by separate storm sewers or other sewage or drainage facilities, or conveyed by snow removal equipment.
Stormwater runoff means water flow on the surface of the ground or in storm sewers, resulting from precipitation.
Stormwater system means constructed and natural features which function together as a system to collect, convey, channel, hold, inhibit, retain, detain, infiltrate, divert, treat, or filter stormwater. “Stormwater system” includes both public and privately owned features.
Coefficient means a number that represents the quantified relationship of each variable to the assessed value of a property when derived through a mass appraisal process
Stormwater management BMP means an excavation or embankment and related areas designed to retain stormwater runoff. A stormwater management BMP may either be normally dry (that is, a detention basin or infiltration system), retain water in a permanent pool (a retention basin), or be planted mainly with wetland vegetation (most constructed stormwater wetlands).
water meter means any apparatus for measuring or showing the volume of water supplied to, or of effluent discharged from any premises;
Stormwater management means the programs to maintain quality and quantity of stormwater runoff to pre-development levels.
Stormwater management system means any equipment, plants,
Stormwater management facility means a control measure that controls stormwater runoff and changes the characteristics of that runoff including, but not limited to, the quantity and quality, the period of release or the velocity of flow.
Stormwater management planning area means the geographic area for which a stormwater management planning agency is authorized to prepare stormwater management plans, or a specific portion of that area identified in a stormwater management plan prepared by that agency.
Irrigation efficiency (IE) means the measurement of the amount of water beneficially used divided by the amount of water applied. Irrigation efficiency is derived from measurements and estimates of irrigation system characteristics and management practices. The irrigation efficiency for purposes of this ordinance are 0.75 for overhead spray devices and 0.81 for drip systems.
Wastewater Facilities means the structures, equipment, and processes required to collect, carry away, and treat domestic and industrial wastes and dispose of the effluent.
Stormwater management measure means any practice, technology, process, program, or other method intended to control or reduce stormwater runoff and associated pollutants, or to induce or control the infiltration or groundwater recharge of stormwater or to eliminate illicit or illegal non-stormwater discharges into stormwater conveyances.
Stormwater management plan means the set of drawings and other documents that comprise all the information and specifications for the programs, drainage systems, structures, BMPs, concepts and techniques intended to maintain or restore quality and quantity of stormwater runoff to pre-development levels.
Water Year means the period commencing with October 1 of 1 year 20 and extending through September 30 of the next; and
high-efficiency cogeneration means cogeneration meeting the criteria laid down in Annex II;

Project Water means water made available for delivery to the contractors by project conservation facilities and the transportation facilities included in the System.
Raw water means water withdrawn from a reservoir or well prior to any physical treatment of such water.
Storm water means storm water runoff, snow melt runoff, and surface runoff and drainage.
Water Service means the procurement, treatment, and distribution of water for domestic use or any other purpose for which water can be used.
Transportation Facilities means any physical facility that moves or assist in the movement of people or goods including facilities identified in OAR 660-012-0020 but excluding electricity, sewage, and water systems.
