[HISTORY: Adopted by the Annual Town Meeting of the Town
of Wayland 4-10-2008 by Art. 25;
amended in its entirety by the Annual Town Meeting 4-6-2015 by Art. 19. Subsequent amendments noted
where applicable.]
A.
The purpose of this chapter is to:
(1)
Protect the quantity and quality of water recharge to the Town's
water supply aquifers;
(2)
Protect cold water fisheries and other designated outstanding water
resources from discharges of toxic pollutants, nutrients, and temperature
changes;
(3)
Protect and enhance wildlife habitat;
(4)
Protect streams, rivers, and private property from additional flood
damage from changed flow patterns.
B.
This chapter seeks to implement these goals through the following
objectives:
(1)
Complement and expand upon the requirements of state and federal
statutes and regulations relating to stormwater and illicit discharges;
(2)
Establish provisions for long-term responsibility for and maintenance
of structural stormwater control facilities/devices and nonstructural
stormwater management practices to ensure they continue to function
as designed, are maintained, and pose no threat to public safety;
(3)
Ensure that soil erosion control measures, sedimentation control
measures and stormwater runoff control practices are incorporated
into the site planning and design process and are implemented and
maintained;
(4)
Require that new development and redevelopment maintain the pre-development
hydrologic characteristics in the post-development state as nearly
as practicable in order to reduce flooding, stream bank erosion, and
non-point source pollution, to maintain the integrity of stream channels
and aquatic habitats and to provide protection from property damage.
(5)
Establish minimum design criteria for the protection of properties
and aquatic resources downstream from land development and land conversion
activities from damages due to increases in volume, velocity, frequency,
duration and peak flow rate of stormwater runoff; establish minimum
design criteria for BMP measures to minimize point and non-point source
pollution from stormwater runoff which would otherwise degrade water
quality;
(6)
Control the volume and rate of stormwater runoff resulting from land
disturbance activities; establish minimum post-development stormwater
management standards and design criteria for the regulation and control
of stormwater runoff quantity and quality; establish minimum design
criteria for the protection of properties and aquatic resources downstream
from land development, redevelopment and land conversion activities
from damages due to increases in volume, velocity, frequency, duration
and peak flow rate of stormwater runoff;
(7)
Establish minimum design criteria for BMP measures to minimize point
and non-point source pollution from stormwater runoff which would
otherwise degrade water quality;
(8)
Require that there be no increase in post-development discharge from
storm drainage systems or any other changes in post-development conditions
that alter the post-development watershed boundaries;
(9)
Require that all catch basin discharge points or other point source
discharge points shall be designed with structures to disperse stormwater
energy;
(10)
Encourage the use of non-structural stormwater management and
low-impact stormwater site design standards such as reducing impervious
cover and the preservation of open space and other natural areas;
(11)
Require practices to control waste such as discarded building
materials, truck washouts, chemicals, litter and sanitary waste at
construction sites that may cause adverse impacts to water quality;
(12)
Ensure compliance with the provisions of this bylaw through
inspection, monitoring and enforcement;
(13)
Establish provisions to ensure there is an adequate funding
mechanism, including a performance guarantee, for the proper review,
inspection and long-term maintenance of stormwater facilities implemented
as part of this chapter;
(14)
Establish administrative procedures and fees for the submission,
review, approval or disapproval of stormwater management plans, and
for the inspection of approved active projects, and long-term follow
up.

and implementation of this chapter.
