CHANNEL. A natural or constructed/manmade watercourse with definite bed and banks to confine and conduct continuously or periodically flowing water. CHANNEL FLOW is that water which is flowing within the limits of the defined channel.
CLEAN WATER ACT (CWA). Federal regulation that prohibits the discharge of pollutants to waters of the United States unless the discharge is in accordance with an NPDES permit.
CLEARING. Any activity that removes the vegetative surface cover.
CRITICAL AREA. A site difficult to stabilize due to exposed subsoil, steep slope, extent of exposure, or other conditions.
DETENTION. The temporary delay of storm water runoff prior to discharge into receiving waters.
DEVELOPER. Any individual, firm, corporation, association partnership, or trust involved in commercial proceedings to affect development of land for himself, herself or others.
DRAINAGE BASIN. A part of the surface of the earth that is occupied by and provides surface water runoff into a storm water management system, which consists of a surface stream or a body of impounded surface water together with all tributary surface streams and bodies of impounded surface water.
DRAINAGE WAY. Any channel that conveys surface runoff throughout the site.
DRAINAGE/DRY WELL. A bored, drilled, driven, dug, or naturally occurring shaft or hole with a depth greater than the largest surface dimension; used to drain surface fluid, primarily storm water runoff, into a subsurface formation.
EPHEMERAL STREAM. A stream or part of a stream that flows only in direct response to precipitation or snowmelt. Its channel is above the water table at all times.
EROSION. The wearing away of land surface by the action of wind, water, gravity, ice, or any combination of those forces.
EROSION PREVENTION AND SEDIMENT CONTROL PLAN (EPSC). A set of plans prepared by or under the direction of a qualified professional in the State of Kentucky indicating the specific measures and sequencing to be used to control sediment and erosion on a development site during and after construction.
EXCAVATION. Any portion of land surface or area from which earth has been removed or will be removed; the depth below original ground surface to remaining surface.
EXISTING GRADE. The slope or elevation of existing ground surface prior to cutting or filling.
FILL. Portion of land surface or area to which soil, rock, or other materials have been or will be added; height above original ground surface after the material has been or will be added.
FINISHED GRADE. The final slope or elevation of the ground surface after cutting or filling.
FLOODPLAIN. The relatively flat or lowland area adjoining a river, stream, watercourse, lake, or other body of standing water which has been or may be covered temporarily by floodwater; the 100-year floodplain having a 1% chance of being equaled or exceeded in any given year.
GRADING. Any stripping, cutting, filling or stockpiling of earth or land, including the land in its cut or filled condition, to create new grades.
IMPERVIOUS SURFACE. Any ground or structural surface that water cannot penetrate or through which water penetrates with great difficulty.
KYDOW GENERAL PERMIT. An agreement between the regulating authority (KYDOW) and the permittee which specifies conservation practices that shall be implemented in the construction of activities specified in the terms and conditions of the general permit.
LAND DISTURBANCE. The purposeful act of clearing, grubbing, excavating or grading; disrupting ground surface by or for construction activities, including access/roads, staging, and storage sites producing significant areas of exposed soil and soil piles.
NATIONAL POLLUTANT DISCHARGE ELIMINATION SYSTEM (NPDES). The EPA’s program to control the discharge of pollutants to waters of the United States. NPDES is a part of the federal CWA, which requires point and non-point source dischargers to obtain permits. These permits are referred to as NPDES PERMITS.
NOTICE OF INTENT (NOI). A formal notice to the KYDOW that a construction project seeking coverage under a general plan is about to begin.
NOTICE OF TERMINATION (NOT). A formal notice to the KYDOW that a construction project is complete and seeking release for the EPSC and the state general permit.
PERIMETER CONTROL. A barrier that prevents sediment from leaving a site by filtering sediment-laden runoff or diverting it to a sediment trap or basin.
PERMIT PHASING. Clearing a parcel of land in distinct phases, with the stabilization of each phase completed before the clearing of the next.
PERMITTEE. The person, company, contractor, or developer who is responsible for the land-disturbing activity.
PERMITTING AGENCY. The City of Ashland’s Public Services Department, or other city department deemed appropriate, responsible for review and approval permits and EPSC plans.
PUBLIC STORM DRAIN. Drain system provided and maintained by the City of Ashland, that is designed to help maintain storm water runoff and also provides inlets for water to travel to holding areas attempting to remove excessive water from streets and other areas.
SEDIMENT. Solid material, both mineral and organic, that is in suspension, is being transported, or has been moved from its site of origin by air, water, or gravity as a product of erosion.
SEDIMENT CONTROL. Measures that prevent eroded sediment from leaving the site.
SITE. A parcel of land or a contiguous combination thereof, where grading work is performed as a single unified operation subject to erosion of sedimentation as a result of cutting, filling, grading, or other disturbances of the soil.
SITE DEVELOPMENT PERMIT. A permit issued by the Ashland Public Services Department for the construction or alteration of ground improvements and structures for the control of erosion, runoff, and grading.
SITE WASTE CONTROL. The requirements set forth in this chapter are also intended to control or eliminate waste from construction site operators that may cause adverse impacts to water quality.
STABILIZATION. The use of practices that prevent exposed soil from eroding.
START OF CONSTRUCTION. The first land- disturbing activity associated with a development, including land preparation such as clearing, grading, and filling; installation of streets and walkways; excavation for basements, footings, piers, or foundations; erection of temporary forms; and installation of accessory buildings such as garages.
STORM WATER MANAGEMENT PLAN (SWMP). A plan which is based on hydrologic and hydraulic calculations to determine flood stage and required improvement to minimize impacts by development.
STORM WATER POLLUTION PREVENTION PLAN (SWPPP). A plan required by storm water regulations or permits that includes site map(s), an identification of construction/contractor activities that could cause pollutants in the storm water, and a description of measures or practices to control these pollutants. This is synonymous with the term BMP PLAN used in the KYDOW general permit.
TEMPORARY PROTECTION. Short-term stabilization of erosive or sediment producing areas.
VEGETATIVE PROTECTION. Stabilization of erosive or sediment producing areas by covering the soil with any of the following materials: permanent seeding for long-term vegetative cover, short-term seeding for temporary vegetative cover, sodding, producing areas covered with a turf of perennial sod- forming grass, tree planting, or other planting.
WATERCOURSE. Any body of water, including, but not limited to, lakes, ponds, rivers, streams, and bodies of water designated as part of the storm water conveyance system.
WATERWAY. A channel that directs surface runoff to a watercourse or to the public storm drain.
