CLEAR CUTTINGThe harvest of timber products in a fashion which removes all species of trees down to a two-inch diameter at breast height.
CONTINUAL FLOWA flow of water which persists for an extended period of time. This flow may be interrupted during periods of drought or during the low flow period of the annual hydrological cycle, June through September, but it recurs in prolonged succession.
DEPOSITIncludes, but shall not be limited to, fill, grade, dump, place, discharge or emit.
DESIGNATED AGENTIndividual(s) designated by the Agency to carry out its functions and purposes.
DISCHARGEThe emission of any water substances or material into watercourses or wetlands, whether or not such substance causes pollution.

FEASIBLEThe ability to be constructed or implemented consistent with sound engineering principles.
GARDENINGThe tilling of soil and the planting, cultivating and harvesting of vegetable matter.
GRAZINGUsing any tract of land to feed or supply farm animals with grass or pasture, to tend farm animals or to feed or grow silage and herbage.
HARVESTING OF CROPSThe gathering of plants or animals or plant or animal products which have been grown to be harvested.
MANAGEMENT PRACTICESA practice, procedure, activity, structure or facility designed to prevent pollution or other environmental damage or to maintain or enhance existing environmental quality. Such management practices include, but are not limited to: erosion and sedimentation controls, restrictions on land use or development, construction setbacks from wetlands or watercourses, proper disposal of waste materials, procedures for equipment maintenance to prevent fuel spillage, construction methods to prevent flooding or disturbance of wetlands or watercourses, procedures for maintaining continuous stream flows, confining construction that must take place in watercourses to times when water flows are low and fish and wildlife will not be adversely affected.
MARSHAn area normally covered with shallow water, subject to seasonal variations, that contains an association of herbaceous, soft-stemmed plants as marsh vegetation. Typical examples of marsh species are listed in the booklet titled "Inland Wetland Plants of Connecticut," May 1973.
MATERIALAny substance, solid or liquid, organic or inorganic, including, but not limited to: soil, sediment, aggregate, land, gravel, clay, bog, peat, mud, debris, sand, refuse or waste.
NURSERIESLand used for propagating trees, shrubs or other plants for transplanting, sale or for use as stock for grafting.
PERMITThe whole or any part of any license, certificate or approval or similar form of permission which may be required of any person by the provisions of these regulations under the authority of the Inland Wetlands Agency.
PERMITTEEThe person to whom such permit has been issued.
PERSONAny person, firm, partnership, association, corporation, company, organization or legal entity of any kind, including municipal corporations, government agencies or subdivisions thereof.
POLLUTIONThe contamination or rendering unclean or impure of, or harmful thermal effect on, any watercourses or wetlands by reason of any waste or other materials discharged or deposited therein by any public or private sewer or otherwise so as to come in contact with any waters, directly or indirectly. This includes, but is not limited to, erosion and sedimentation or turbidity resulting from any filling, land clearing or excavation activity.
POORLY DRAINED SOILSoils wherein water is removed so slowly that the soil is saturated periodically during the growing season or remains wet for long periods. Poor drainage results from a high water table, a slowly pervious layer within the profile, seepage, nearly continuous rainfall or a combination of these.
PRUDENTEconomical and otherwise reasonable in light of the social benefits to be derived from the proposed regulated activity, provided that cost may be considered in deciding what is prudent and further, provided, that a mere showing of expense will not necessarily mean an alternative is imprudent.
REGULATED ACTIVITYAny operation within or use of a wetland or watercourse involving removal or deposition of material or any obstruction, construction, alteration or pollution of such wetland or watercourse, but shall not include the activities specified in §
60A-4 of these regulations. Regulated activity shall also include activity(ies) in nonwetland areas, such as (but not limited to) clear cutting, land clearing, soil disturbance, regrading of land or construction of buildings, which may have the effect of increasing or decreasing drainage or increasing sedimentation or erosion or causing discharge, deposition within or pollution to the wetland or watercourse.
REGULATED AREAAny inland wetlands or watercourses as defined in these regulations.
REMOVEIncludes, but shall not be limited to, drain, excavate, mine, dig, dredge, suck, grub, clear cut, bulldoze, dragline or blast.
RENDERING UNCLEAN OR IMPUREAny undesirable alteration of the physical, chemical or biological properties of any watercourses or wetlands, including, but not limited to, change in color, odor, turbidity or taste.
SIGNIFICANT ACTIVITY, IMPACT OR MAJOR EFFECTIncluding but not limited to:
A. Any activity involving a deposition of material which will or may have a substantial adverse affect on the regulated area or on another part of the inland wetland or watercourse system.
B. Any activity involving a removal of material which will or may have a substantial adverse effect on the regulated area or on another part of the inland wetland or watercourse system.
C. Any activity which substantially changes the natural channel or may inhibit the natural dynamics of a watercourse system.
D. Any activity which substantially diminishes the natural capacity of an inland wetland or watercourse to support desirable plant or animal life, prevent flooding, supply water, assimilate waste, facilitate drainage and/or provide recreation and open space.
E. Any activity which causes a substantial diminution of flow of a natural watercourse or groundwater levels of the regulated area.
F. Any activity which creates hydrological conditions which may adversely affect the health, welfare and safety of any individual or the community.
G. Any activity which destroys unique wetland or watercourse areas having demonstrable scientific or educational value.
H. Any activity which causes or has the potential to cause pollution of a wetland or watercourse.
SOIL SCIENTISTAn individual duly qualified in accordance with standards set by the Federal Office of Personnel Management.
SUBMERGED LANDSThose lands which are inundated by water on a seasonal or more frequent basis.
SWAMPAn area with a water table at or near the surface of the ground throughout most of the year and containing vegetation dominated by an association of trees and/or shrubs recognized as swamp species. Typical examples of swamp species are listed in the booklet titled "Inland Wetland Plants of Connecticut," May 1973.
VERY POORLY DRAINED SOILSoils wherein water is removed from the soil so slowly that free water remains at or on the surface during most of the growing season. Very poorly drained soils are commonly level or depressed and are frequently ponded. Where rainfall is high and nearly continuous, very poorly drained soils can have moderate or high slope gradients.
WASTESewage or any liquid, gaseous, solid or radioactive substance which may pollute any of the watercourses or wetlands.
WATERCOURSERivers, streams, brooks, waterways, lakes, ponds, marshes, swamps, bogs and all other bodies of water, natural or artificial, vernal or intermittent, public or private, which are contained within, flow through or border upon the City of Norwalk or any portion thereof, not regulated pursuant to Sections 22a-28 through 22a-35 of the Connecticut General Statutes (the Tidal Wetlands Act), as amended. An intermittent watercourse shall be delineated by a defined permanent channel and bank and the occurrence of two or more of the following characteristics:
A. Evidence of scour or deposits of recent alluvium or detritus;
B. The presence of standing or flowing water for a duration longer than a particular storm incident; and
C. The presence of hydrophytic vegetation.
WETLANDSLand, including submerged land, not regulated pursuant to Sections 22a-28 through 22a-35, inclusive, of the Connecticut General Statutes (the Tidal Wetlands Act), as amended, which consists of any of the soil types designated as poorly drained, very poorly drained, alluvial and floodplain by the National Cooperative Soils Survey, as it may be amended from time to time, of the Natural Resources Conservation Service of the United States Department of Agriculture (USDA). Such areas may include filled, graded or excavated sites which possess an aquic (saturated) soil moisture regime as defined by the USDA Cooperative Soil Survey.
