Following the method established in § 218-86, the calculation of the formula for the third and all subsequent quarters shall be performed by the Building Official and shall be submitted to the Town Council, the Planning Commission and posted in the office of the Town Clerk not less than thirty (30) days prior to the commencement of the quarter for which the quota is to be applied. To assist the Building Official in his/her calculation, the Building Official shall request, in writing, that the Superintendent of the Chariho Regional School District supply him/her the number of available seats in the school district based on the current capacity less the actual enrollment as of October 1 of the school calendar year, and the increase in seat capacity, projected from January 1, 2000 to December 31, 2009 based upon an adopted plan of the Chariho Regional School Committee. The Building Official shall monitor the Chariho Regional School District's overall capacity by checking with the Superintendent of the Chariho Regional School District every first day of February, March, August and November to determine if there are any changes in available seats. If there are no changes, the Building Official shall notify the Town Clerk that the number of permits to be issued the next quarter will be the same as the previous quarter. If there are changes in seats, the Building Official shall recalculate the quota and notify the Town Clerk of the new number of permits to be issued the next quarter. Notwithstanding any changes, the quota shall not change in the middle of any given quarter.
