(a) Interpretation of Terms and Words.
(1) Words used in the present tense include the future tense and the singular includes the plural, unless the context clearly indicates the contrary.
(2) The term “shall” is always mandatory and not discretionary; the word “may” is permissive. The term “should” is permissive but indicates strong suggestion.
(3) The word or term not interpreted or defined by this section shall be construed according to the rules of grammar and common usage so as to give these Rules their most reasonable application.
(b) The following terms shall have the following meanings, as used in this chapter:

Disturbed Area: An area of land subject to erosion due to the removal of vegetative cover and/or soil moving activities, including filling.
Ditch: An open channel, either dug or natural, for the purpose of drainage or irrigation with intermittent flow.
Drainage: The removal of excess surface water or ground water from land by surface or subsurface drains.
Drainage Surface Area: An area, measured in a horizontal plane, enclosed by a topographic divide from which surface run-off from precipitation normally drains by gravity into a stream, river or lake above the specified point of measurement.
Drainage Improvement: As defined in Ohio R.C. 6131.01 (C), and/or conservation works of improvement, Ohio R.C. Chapters 1511 and 1515.
Engineer: A Professional Engineer registered by the State of Ohio.
Erosion: The process by which the land surface is worn away by the action of wind, water, ice, gravity or any combination of those forces.
Erosion & Sediment Control: The control of soil material, both mineral and organic, during soil disturbing activity to prevent its transport out of the disturbed area by means of wind, water, ice or gravity.
Farm: Land or water devoted to growing crops and nursery crops.
Grading: Excavating, filling, or stockpiling of earth material or any combination thereof, including the land in its excavated or filled condition.
Impervious: That which does not allow infiltration.
Inspector: The delegated representative of the developer to inspect and maintain erosion/sediment control practices on site and complete reports for review by the City of Louisville. Any inspector in the City of Louisville requires a minimum of 16 hours of training and a certificate of completion by the Stark SWCD.
Landslide: A rapid mass movement of soil and rock materials downhill under the influence of gravity.
Multi-family development: Apartments, condominiums, duplexes or other similar buildings housing more than one family
One Hundred-Year Frequency Storm: A storm that is capable of producing rainfall expected to be equaled or exceeded on the average of once in 100 years. It may also be expressed as an exceedence probability with a 1 percent chance of being equaled or exceeded in any given year
Person: Any individual, corporation, firm, trustee, commission, board, public or private partnership, joint venture, agency, unincorporated association, municipal corporation, county or state agency, the federal government or any combination thereof.
Pre-construction Meeting: A meeting between the City of Louisville, including the Inspector assigned to the project, and all principal parties, prior to the start of any construction, at a site that requires an Erosion and Sediment Control Plan.
Pre-Winter Stabilization Meeting: A meeting between the Louisville Inspector and all principal parties, prior to October 1, in order to plan winter erosion and sediment controls for a site that requires an Erosion and Sediment Control Plan.
Qualified Person: Professional Engineer, Surveyor, Landscape Architect, Soil Conservationist, Certified Professional in Erosion/Sediment Control. All persons who submit a plan for review must complete a mandatory minimum of 20 hours of accredit training in erosion sediment control instituted by the Stark SWCD. (See Section 1324.04(b))
Retention Structure: A permanent structure whose primary purpose is to permanently store a given volume of storm water runoff for release of the given volume by infiltration and/or evaporation.
Seeding/Temporary Vegetation: The placement of seed and mulch to disturbed soil. A seeding must result in vegetation.
Sediment: Soils or other surface materials that can be transported or deposited from its site of origin by the action of wind, water, ice or gravity as a product of erosion.
Sedimentation: Deposition of sediment particles in water bodies.
Sediment Basin: A temporary barrier or other suitable retention structure built across an area of water flow to intercept runoff and allow transported sediment to settle and be retained prior to discharge into waters of the State.
Sediment Pollution: Degradation of Waters of the State by sediment as a result of failure to apply management or conservation practices to abate wind or water soil erosion, specifically in conjunction with soil-disturbing activities on land used or being developed for commercial, industrial, residential or other non-farm purposes.
Sloughing: A slip or downward movement of an extended layer of soil resulting from the undermining action of water or the earth-disturbing activity of man.
Soil Conservation: The use of the soil within the limits of its physical characteristics and protecting it from unalterable limitations of climate and topography.
Soil-Disturbing Activity: A clearing, grading, excavating, filling or other alteration of the earth’s surface where natural or man-made ground cover is destroyed, which may result in, or contribute to, erosion and sediment pollution.
Soil Loss: Soil moved from a given site by the forces of erosion, measured using “T”.
Stabilization: The installation of vegetative and/or structural measures to establish a soil cover in order to reduce soil erosion by storm water runoff, wind, ice, and gravity.
Storm Drain: A conduit, pipe, or human-made structure, which serves to transport storm water runoff.
Storm Water Management: Runoff water safely conveyed or temporarily stored and released at an allowable rate to minimize erosion and flooding.
Storm Water Runoff: The direct response of a watershed to precipitation and includes the surface and subsurface runoff that enters a stream, ditch, storm sewer or other concentrated flow during and following the precipitation.
Stream: A body of water running or flowing on the earth’s surface in which flow may be perennial and/or seasonally intermittent.
Subsoil: That portion of the soil below the topsoil or plow layer, beginning 6-12” below surface down to bedrock parent material.
T: The soil loss tolerance expressed in tons per acre per year as determined by the USDA Revised Universal Soil Loss Equation (RUSLE).
Temporary Soil Erosion and Sediment Control Measures: Interim control measures which are installed or constructed to control soil erosion or sedimentation until permanent soil erosion control measures are established.
Top soil: The upper layer of soil that is usually darker in color and richer in organic matter and nutrients than the subsoil.
Unstable Soils: A portion on land surface or area which is prone to slipping, sloughing, landslides or is identified by Natural Resource Conservation Service, USDA methodology as having a low soil strength.
Watercourse: A definite channel with bed and banks within which concentrated water flows, either continuously or intermittently; e.g. streams.
Watershed: The total drainage area contributing runoff to a single point.
