Pertinent definitions are provided in §
386-2 of the Town of Plainville Stormwater Management Bylaw.
The Stormwater Authority 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 Stormwater Authority and be in an amount deemed sufficient by the Stormwater Authority to ensure that the work will be completed in accordance with the permit. If the project is phased, the Stormwater Authority 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 Stormwater Authority has received the final report as required by §
895-14 and issued a certificate of completion pursuant to §
895-15.
Upon completion of the work described in the land disturbance
permit, or administrative land disturbance review if required, the
permittee shall submit a final report, including a cover letter and
topographic as-built plan, including electronic pdf copy, stamped
by a MA professional land surveyor (PLS) and/or MA registered professional
engineer (P.E.) as applicable, certifying that the site has been developed
in substantial compliance with the approved plan, including all permanent
erosion control devices, stormwater management facilities, and any
approved changes and modifications. All deviations and discrepancies
from the approved plan shall be noted in the cover letter. The as-built
drawings must depict all on-site controls, both structural and nonstructural,
designed to manage the stormwater associated with the completed site
(post-construction stormwater management). The final report shall
also include documentation to verify the stormwater management system
has been properly operated and maintained in accordance with the approved
O&M plan.
