Performance Guarantee: As a condition of site plan approval, the Planning Board shall determine whether to require that a performance bond, deposit of money, negotiable securities, or other such surety acceptable to the Planning Board, be posted with the Town. This surety is to cover costs of non-building construction, including, but not limited to, any street disturbance, utilities, erosion control measures, stormwater management measures, and other on-site or off-site improvements which present a public health and safety hazard or nuisance if left incomplete or improperly constructed. The Board may also require that an amount be included for restoration of land disturbed during the course of construction. The amount of security shall be determined based on an estimate prepared by a professional cost estimator paid for by the Applicant, which estimate may be confirmed or increased by the Board. The Town may use the secured funds for their stated purpose in the event that the applicant does not complete all improvements in a manner satisfactory to the Board within two years from the date of approval, or the final date of the last extension of such approval, if any.
