Placing of materials which have a reasonable likelihood of contributing to pollution or of impacting water quality through surface runoff, groundwater infiltration or airborne transport, including but not limited to yard and landscaping wastes and debris, slash, soils and sediments, wood chips, mulch, grit, gravel or other organic and inorganic materials.
APPLICATION FOR PERMIT UNDER THE BYLAWThe written application filed by any person intending to remove, fill, dredge, discharge into, build upon, otherwise alter or carry out activity not exempted from the Bylaw in an area subject to regulation under the Bylaw or activity that will significantly alter, pollute or degrade these areas. It shall be made on WPA Form 3 or 4.
AREAS SUBJECT TO FLOODINGDepressions or closed basins that serve as ponding areas for runoff, snowmelt, heavy precipitation, or high groundwater that has risen above the ground surface in most years, and areas that flood from a rise in a bordering waterway or water body.
BUILDINGAny structure, requiring a building permit under the State Building Code, 780 CMR
101.0 et seq., and/or Wenham Bylaws, that is enclosed within exterior walls or fire walls, built, erected and framed of a combination of any materials, whether portable or fixed, having a roof, to form a structure for the shelter of persons, animals or property. For the purpose of this definition, "roof" shall include an awning or similar covering, whether or not permanent in nature. The word "building" shall be construed where the context requires as though followed by the words "or parts thereof."
BYLAWThe Town of Wenham Water Resources Protection Bylaw, General Town Bylaws Chapter
242.
CONTINUOUS STREAMAll flowing watercourses shall be considered to be a continuous stream unless a preponderance of evidence deemed acceptable to the Conservation Commission rebutting this presumption is presented.
A. Information necessary to overcoming this presumption includes, but is not limited to, direct observation and documentation of the:
(1) Absence of a continuous sheet of surface water throughout the watercourse, or relevant segment, for a minimum of five consecutive days annually in most years (excluding periods when local drought or other conditions abnormally lowering the water table are known to exist, or due to water withdrawals), as witnessed by a member of the Conservation Commission or its staff, which shall be considered definitive evidence in overcoming the presumption of continuous status;
(2) Absence of gravel, mineral, and riffle substrate;
(3) Absence of a clearly defined flow channel;
(4) Absence of bank undercutting; or
(5) Presence of established nonaquatic plants in the flow path (i.e., plants that are unable to grow in continuously submerged conditions).
B. The Conservation Commission will also consider estimates from modeling studies of surface water and groundwater hydrology in the relevant watershed. However, such information will only be considered as evidence in conjunction with the observable indicators noted above.
C. Observational evidence shall, in all instances, take precedence over estimates, calculations, and other inferential evidence.
D. The Conservation Commission shall consider all of the evidence available together, judging the validity and reliability of the information, and base its determination on the preponderance of acceptable evidence.
EMERGENCY WORKWork falling within the jurisdiction of the Bylaw but where delays in its initiation and/or completion would jeopardize public health, safety and welfare.
HYDRIC SOILSSoils which, in an undrained condition, display characteristics of a hydrologic regime of periodic annual saturation due to high groundwater, flooding or ponding that results in an anaerobic condition which favors the growth and regeneration of hydrophytic (wetland) vegetation. The following types of soils are hydric:
A. All organic soils (Histosols) except Folists.
B. Mineral soils in Aquic subgroups, Albolls suborder, Salorthids great group, or Pell great groups of Vertists which are:
(1) Somewhat poorly drained (as the soils type may be defined from time to time by the U.S. Natural Resources Conservation Service) and have a water table less than 15 cm from the surface at some time during the growing season; or
(2) Poorly drained or very poorly drained (as those soil types may be defined from time to time by the U.S. Natural Resources Conservation Service) and have either:
(a) A water table at less than 30 cm from the surface at some time during the growing season if permeability is equal to or greater than 15 cm/hour in all layers within 60 cm; or
(b) A water table at less than 45 cm from the surface at some time during the growing season if permeability is less than 15 cm/hour in any layers within 60 cm.
(3) Mineral soils that are ponded during any part of the growing season; and
(4) Mineral soils that are frequently flooded for long duration (more than seven days) or flooded for very long duration (more than one month) during the growing season.
INTERMITTENT PONDAn area subject to flooding that forms temporary confined bodies of water during periods of high water table and high input from spring runoff or snowmelt or heavy precipitation and supports wetland vegetation and does not serve as breeding habitat for species of amphibians and is not a vernal pool.
INTERMITTENT STREAMA body of running water that does not flow throughout the year, including brooks and creeks, evidenced by a hydraulic connection between bodies of water, and which flows within, into or out of an area subject to protection under the Bylaw.
PROJECT REVIEWA review by a qualified professional engaged by the Commission that examines engineering design, calculations and other information provided by the applicant and other sources for completeness, accuracy, and effectiveness, including but not limited to the following: runoff calculations, drainage and drainage structures, slopes, headwalls and retaining structures, siting of septic system relative to resource areas, soils information, subsurface hydrology, plans for sequencing construction, and proposed erosion and sedimentation controls.
RESOURCE AREAAll areas subject to regulation under the Bylaw as listed in the Bylaw and §
500-2A.
SPECIAL ENVIRONMENTAL IMPACT REVIEWA review by a qualified professional that examines the information provided by the applicant and other sources of implications and impacts of a project on resources, including but not limited to hydrology, wildlife, wildlife habitat, water quality, and the other values protected by the Bylaw, and function and feasibility of proposed wetland replication areas.
STRUCTUREA combination of materials assembled or fabricated at a fixed location to give support, storage, or shelter, such as a building, framework, retaining wall, tent, reviewing stand, platform, bin, fences over six feet high, sign, flagpole, recreational tramway, mast for radio antenna, or the like. The word "structure" shall be construed, where the context requires, as though followed by the words "or part or parts thereof."
WORKThe performance of activities, including, but not limited to, the following activities: filling, excavation, grading, operation of motorized construction equipment, and storage or stockpiling of earth or construction materials.
