The owner shall provide to the Town a surety or cash bond, irrevocable letter of credit, or other means of security acceptable to the Town prior to the issuance of any permit, approval or waiver involving the grading, construction or operation of a stormwater management practice, system or facility. The amount of the security shall not be less than the total estimated construction cost of the stormwater management practice, system or facility. The bond required in this section shall include provisions relative to forfeiture for failure to complete work specified in the approved stormwater management plan, compliance with all of the provisions of this chapter, and other applicable laws and regulations, as well as any time limitations for making such practice, system or facility fully operational and completed.
The performance bond or other security shall not be fully released without a final inspection of the completed work by the enforcement authority, submission of sealed as-built plans by the owner to the enforcement authority, and certification of completion by the owner to the enforcement authority that the stormwater management facilities comply with the approved plan and the provisions of this chapter. A procedure may be used to release parts of the bond or other security held by the Town after various stages of construction have been completed and accepted by the enforcement authority after inspection by the enforcement authority. The procedures used for partially releasing performance bonds or other security must be specified by the enforcement authority in writing, prior to stormwater management plan approval.
