Stormwater Operation & Maintenance
34 Glenore Circle
North Andover, MA 01845
Beginning with the construction of the drainage system, and continuing in perpetuity thereafter, the owner(s)
of the site shall maintain in accordance with the following schedule:
a. Pavement and walkways shall be swept in the early spring immediately after snow melt
b. Roof drain inlets,downspouts, and roof drain pipes - All components of the roof drain collection
system shall be inspected at least 2 times per years Sediments and debris shall be removed and
disposed of in accordance with all applicable federal, state, and local laws. Any components that
become damaged shall be repaired or replacd immediately upon discovery to assure proper
conveyance of stormwater runoff into the drywell systems.
c. Infiltration Chambers —The level of water in the infiltration chambers shall be monitored during and
after heavy rain storms at least 2 times per year during the ftrst year of operati<;m and at least twice
annually thereafter for evidence of clogging or other problems. If water does not leave the chambers
within 72 hours after the storm, or if water breaks out on the surface above the system,or ifthe roof
collection system begins to overflow frequently (for the 10 year storm intensity or less intense storms),
the infiltration bed is likely clogged. The infiltration bed shall be cleaned and repaired or replaced as
needed to maintain proper functioning.
d. Vegetation shall be maintained in healthy condition to prevent erosion and sedimentation in the
drainage system and wetland resource areas.
e. Existing Catchbasin—The existing catchbasin shall be inspected twice a year. Any accumulated
sediment, branches, or leaves shall be removed from the grate area to allow free flow of water.
Additionally, the inside of the catchbasin should be inspected to see if any accumulated sand or
sediment needs to be removed from the basin.
f. Permeable Bluestone paver—Twice a year the pavers shall be inspected after a 1"rain storm to see how
water infiltrates thru the gaps in the pavers into the underlying base. The owner shall avoid placing
sand on the pavers during winter conditions.
Attached is a simple sketch plan which provides an illustration of the stormwater BMP's referenced above with
