(c) In the case of a subdivision plan approved on or after October 1, 1977, failure to complete all work within such five-year period or any extension thereof shall result in automatic expiration of the approval of such plan provided the commission shall file on the land records of the town in which such subdivision is located notice of such expiration and shall state such expiration on the subdivision plan on file in the office of the town clerk of such town, and no additional lots in the subdivision shall be conveyed by the subdivider or his successor in interest as such subdivider except with approval by the commission of a new application for subdivision of the subject land. If lots have been conveyed during such five-year period or any extension thereof, the municipality shall call the bond or other surety on said subdivision to the extent necessary to complete the bonded improvements and utilities required to serve those lots. “Work” for purposes of this section means all physical improvements required by the approved plan, other than the staking out of lots, and includes, but is not limited to, the construction of roads, storm drainage facilities and water and sewer lines, the setting aside of open space and recreation areas, installation of telephone and electric services, planting of trees or other landscaping, and installation of retaining walls or other structures.

(d) Notwithstanding the provisions of this section, any subdivision approval made under this section on or before October 1, 1991, shall expire not more than seven years from the date of such approval and the commission may grant one or more extensions of time to complete all or part of the work in connection with such subdivision, provided the time for all extensions under this subsection shall not exceed ten years from the date the subdivision was approved. If the subdivider or his successor in interest submits evidence to the commission that completion of the project was delayed because of a state or federal construction project, the approval shall expire not more than ten years from the date of such approval and the commission may grant one or more extensions of time to complete all or part of the work in connection with such subdivision, provided the time for all extensions shall not exceed fifteen years from the date the subdivision was approved. If the subdivider or his successor in interest prevails in an appeal of a decision of the commission on the subdivision under section 8-8 , the time to complete the subdivision shall be tolled for the time of such appeal and until the commission implements the judicial decision.
