All streets to be closed require a fully signed Detour Route in accordance with M.U.T.C.D. standards. The City Engineer establishes the maximum number of hours a street can be closed for a particular project. Arterial streets can be closed no longer than 48 hours, while collector or local streets can be closed no longer than 30 days. Before receiving a street cut permit, the contractor must set up an escrow account as a performance guarantee for the timely completion of the project. The amount to be held in escrow is $10,000 on arterial streets and $1,000/day for collector or local streets. The contractor must pay the City $200/hour for every hour an arterial street is not open past the maximum time period or $1,000/day for each and every day a collector or local street is not open past the maximum time period.
