ยง  231-a. Permanent financing of district improvements to be paid from
  general taxation. When the cost of any improvement is  to  be  assessed,
  levied and collected from the several lots and parcels of lands within a
  district  in the same manner and at the same time as other town charges,
  the town board may  finance  said  improvement  pursuant  to  the  local
  finance law. The town board shall raise annually by tax a sum sufficient
  to  pay  the interest and the principal of obligations issued to finance
  such improvement, if not otherwise paid, as the same shall  become  due;
  such  tax  shall be assessed, levied and collected from the several lots
  and parcels of land within the district in the same manner  and  at  the
  same time as the annual tax for other town charges.
Annual collections of such taxes shall be applied by the supervisor in
  payment  of  maturing  obligations and accruing interest, for which such
  taxes were levied. If the total of  annual  collections  of  such  taxes
  shall be less than the amount required for such purposes, the town board
  may direct that surplus moneys not otherwise appropriated be applied.
