Prior to issuance of the permit following approval by the appropriate land use commission or agency, the professional who has been engaged to review the application shall provide to the land use agency an estimate of the cost for said professionals other than Town employees, to inspect construction at reasonable intervals to insure that construction complies with the approved plan, conformance with the Phase II Regulations of the Connecticut Clean Water Act, inspections for reductions of performance bonds, review of plan revisions and documents necessary to implement or complete the plans, and review and inspection of all improvements necessary for Town acceptance of the project infrastructure or for issuance of a certificate of zoning compliance. A fee equal to that estimated cost shall be paid to the Town through the agent issuing the permit prior to the recording of any plan in the land records and prior to the issuance of any permit for construction in accordance with the approval. All charges thereafter by said professionals in connection with a permit shall be charged against the deposit. If the deposit is exhausted, then an additional amount shall be collected based upon the professional's additional estimate of costs before any further work or inspections are conducted. Failure to make an additional deposit shall be grounds for the appropriate enforcement officer to issue a stop work or cease-and-desist order. Upon completion of the project and acceptance by the Town of any project infrastructure or issuance of a certificate of zoning compliance, any excess funds shall be returned to the applicant not later than 60 days following said event.
