Stormwater Management&Erosion Control Bylaw
160-1. Purpose
- A. Increased volumes of stormwater, contaminated stormwater runoff from impervious
surfaces, and soil erosion and sedimentation are major causes of:
1. impairment of water quality in lakes, ponds, streams, rivers, wetlands and
groundwater.
2. decreased flow in lakes,ponds, streams,rivers,wetlands and groundwater;
3 contamination of drinking water supplies;
4. erosion of stream channels;
5. alteration or destruction of aquatic and wildlife habitat;
6. flooding; and,
7. overloading or clogging of municipal and private catch basins and storm drainage
systems; and
8. flooding and erosion on abutting properties.
The United States Environmental Protection Agency has identified sedimentation from land
disturbance activities and polluted stormwater runoff from land development and
redevelopment as major sources of water pollution, impacting drinking water supplies,
natural habitats, and recreational resources. Regulation of activities that result in the
disturbance of land and the creation of stormwater runoff is necessary for the protection of
the Town of North Andover water bodies and groundwater resources, to safeguard the health,
safety, and welfare of the general public and protect the natural resources of the Town.
B. The objectives of this Bylaw are to:
1. Protect water resources;
2. Require practices that eliminate soil erosion and sedimentation;
3. Control the volume and rate of stormwater runoff resulting from land disturbance
activities in order to minimize potential impacts of flooding;
4. Require practices to manage and treat stormwater runoff generated from new
development and redevelopment;
5. Protect groundwater and surface water from degradation or depletion;
6. Promote infiltration and the recharge of groundwater;
7. Prevent pollutants from entering the municipal and private storm drain system;
8. Prevent flooding and erosion to abutting properties.
9. Ensure that soil erosion and sedimentation control measures and stormwater runoff
management practices are incorporated into the site planning and design process and
are implemented and maintained;
10. Ensure , adequate long-term operation and maintenance of stormwater best
management practices;
11. Require practices to control waste such as discarded building materials, concrete
truck washout, chemicals, litter, and sanitary waste at construction sites that may
cause adverse impacts to water quality;
12. Comply with state and federal statutes and regulations relating to stormwater
discharges; and
1
13. Establish the legal authority of the Town of North Andover to ensure compliance
with the provisions of this Bylaw through inspection,monitoring and enforcement.
160-2 Definitions
ABUTTER: The owner(s) of land abutting the land disturbance site.
AGRICULTURE: The normal maintenance or improvement of land in agricultural or
aquacultural use, as defined by the Massachusetts Wetlands,Protection Act(M.G.L. C. 131 §
40) and its implementing regulations (310 CMR 10.00).
ALTERATION OF DRAINAGE CHARACTERISTICS: Any activity on an area of land
that changes the water quality, or the force, quantity, direction, timing or location of runoff
flowing from the area. Such changes include, but are not limited to: change from distributed
runoff to confined, concentrated discharge; change in the volume of runoff from the area;
change in the peak rate of runoff from the area; and change in the recharge to groundwater on
the area.
APPLICANT: Shall be the owner of record of all of the land shown on any plan submitted
for approval to the Planning Board in accordance with the Stormwater Management Bylaw
and Regulations, any person or persons acting on behalf of the applicant for purposes of
preparing and submitting plans and documents to the Planning Board, and may include
engineers, surveyors, contractors or attorneys, and may also include any person or persons
having an equitable interest in the land under an agreement or option to purchase the land.
The owner shall certify in writing the identity of each applicant who is authorized to submit
plans and/or documents and act on behalf of the owner. Without such certification an
applicant shall not act on behalf of the owner. The applicant shall submit the title reference or
references from the Essex County Registry of Deeds indicating the owner of record. All
applications shall include original signatures of all owners.
BEST MANAGEMENT PRACTICE (BMP): An activity, procedure, restraint, or
structural improvement that helps to reduce the quantity or improve the quality of storumwater
runoff.
CONSTRUCTION AND WASTE MATERIALS: Excess or discarded building or
construction site materials that may adversely impact water quality, including but not limited
to concrete truck washout, chemicals, litter and sanitary waste.
CLEARING: Any activity that removes the vegetative surface cover and/or organic layer.
Clearing activities generally include grubbing activity as defined below.
DESIGN CRITERIA: Engineering design criteria as contained in the Storm-water
Regulations authorized under this bylaw.
DETENTION: The temporary storage of storm runoff; used to control the peak discharge
rates, and which provides settling of pollutants.
