Article 79A - Stormwater Mgmt. & Erosion Control

STORMWATER MANAGEMENT AND EROSION CONTROL BY-LAW

Section 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 and flow in lakes, ponds, streams, rivers, wetlands and groundwater;
2.
 contamination of drinking water supplies;
3.
 erosion of stream channels;
4.
alteration or destruction of aquatic and wildlife habitat;
5.
flooding; and,
6.
overloading or clogging of municipal catch basins and storm drainage systems.

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 water bodies and groundwater resources within the Town of Natick, to safeguard the health, safety, and welfare of the general public and protect the natural resources of the Town.

B.  The objectives of this By-Law 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;
6.
promote infiltration and the recharge of groundwater;
7.
 maximize recharge of groundwater in the Natick Aquifer Protection District as defined by Section III-A.5 of the Natick Zoning By-Law;
8.
 prevent pollutants from entering the municipal storm drain system;
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 structural 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
13.
establish the Town of Natick's legal authority to ensure compliance with the provisions of this By-Law through inspection, monitoring and enforcement.

The maintenance plan shall be designed to ensure compliance with this By-Law and that the Massachusetts Surface Water Quality Standards contained in 314 CMR 4.00 are met in all seasons and throughout the life of the system. The Operation and Maintenance plan shall include any requirements deemed necessary by the Conservation Commission to insure compliance with said plan, including without limitation a covenant. The Conservation Commission shall make the final decision of what maintenance option is appropriate in a given situation. The Conservation Commission will consider natural features, proximity of site to water bodies and wetlands, extent of impervious surfaces, size of the site, the types of stormwater management structures, and potential need for ongoing maintenance activities when making this decision. Once approved by the Conservation Commission the Operation and Maintenance Plan shall be recorded at the South Middlesex Registry of Deeds by the permittee, shall run with the land, shall remain on file with the Conservation Commission and shall be an ongoing requirement. The Operation and Maintenance Plan shall conform to the requirements listed in the Regulations adopted by the Conservation Commission for the administration of this By-Law. Stormwater management easements shall be provided by the property owner(s) in areas and as necessary to carry out the required maintenance.

The purpose of such inspections will be to determine the overall effectiveness of the control plan, and the need for maintenance or additional control measures. The permittee or his/her agent shall submit monthly reports to the Conservation Commission or designated agent in a format approved by the Conservation Commission. The Conservation Commission may require, as a condition of approval, that an Environmental Site Monitor, approved by the Conservation Commission, be retained by the applicant to conduct such inspections and prepare and submit such reports to the Conservation Commission or its designated agent.

D.       

Access Permission

- To the extent permitted by law, or if authorized by the owner or other party in control of the property, the Conservation Commission, its agents, officers, and employees may enter upon privately owned property for the purpose of performing their duties under this By-Law and may make or cause to be made such examinations, surveys or sampling as the Conservation Commission deems reasonably necessary to determine compliance with the permit.

Section 12             Surety

The Conservation Commission may require the permittee to post before the start of land disturbance activity, a surety bond, irrevocable letter of credit, cash, or other acceptable security. The form of the bond shall be approved by town counsel, and be in an amount deemed sufficient by the Conservation Commission to insure that the work will be completed in accordance with the permit. If the project is phased, the Conservation Commission may release part of the bond as each phase is completed in compliance with the permit but the bond may not be fully released until the Conservation Commission has received the final report as required by Section 13 and issued a certificate of completion.

Section 13             Final Reports

Upon completion of the work, the permittee shall submit a report (including certified as-built construction plans) from a Registered Professional Engineer (P.E.) or Registered Professional Land Surveyor certifying that all erosion and sedimentation control devices, and approved changes and modifications, have been completed in accordance with the conditions of the approved permit.
