Financial Surety. Owners or operators of large-scale ground-mounted solar photovoltaic projects shall provide a form of surety, either through escrow account, bond or otherwise, to cover the cost of removal and restoration of the site, in an amount and form determined to be acceptable by the Planning Board, but in no event to exceed 125% of the prevailing wage cost of removal, site restoration, and compliance with the additional requirements set forth herein. Such surety shall remain in force for so long as the project is in existence, and the owner shall annually provide the Planning Board and Building Commissioner with proof that the surety continues in effect. Surety shall include oblige notification clause. Lapse of surety shall be a violation of this bylaw and the Town may take appropriate enforcement action. Such surety will not be required for municipally- or state-owned facilities. The project proponent shall submit a fully inclusive estimate of the costs associated with removal, prepared by a qualified engineer. The amount shall include a mechanism for calculating increased removal costs due to inflation. It shall be a condition of every special permit that the Planning Board may, at intervals of no less than five years, request the owner or operator to provide an updated estimate of the cost of removal, and to increase the amount of security accordingly.
