1. When the improvements in any LID are to be acquired, constructed, and installed by a contractor or contractors, and if it appears that consideration of the contract cost plus all other costs of improvements will exceed the estimated cost as it appears on the approving ordinance by 20 percent or more, then at least 30 days before the notice to proceed is given the contractor or contractors, the clerk shall give notice of the estimated increased cost by certificate mailed to the owners of the lots, tracts, and parcels of land within the district at their last known address and shall also publish, on or before the same date, a similar notice at least once in a newspaper of general circulation within the borough.

2. The mailed and published notice shall state the amount and percentage of total cost of the expected additional charges over the last complete estimated cost, and shall further state that unless written objections to the assembly’s ordering the contractor or contractors to proceed are filed with the clerk by the owners of the property within the district within 25 days from the date of the mailing and publishing of the notice, the contractor or contractors will be ordered to proceed, and that the estimate of costs as increased shall be the cost of improvements until all actual costs after completion are known.

3. In the event written objections are filed by owners of property within the district, no notice to proceed shall be given the contractor or contractors and further work on the project shall cease until all objections are settled to the satisfaction of all the benefited landowners, unless a new LID is created pursuant to this chapter. Costs of the project to date of termination shall be considered LID costs and assessed according to the original ordinance creating the LID.
