Updated 9/16/15: noise attenuation requirements for the new Coles building will adhere to the Restrictive Dec.

Maintenance and Protection of Traffic

For each new building project, NYU will prepare a plan and provide diagrams of proposed temporary curb lane and sidewalk closures (an MPT plan), including the duration of closures, the sidewalk protection measures to be installed for pedestrians, and other MPT items.

Updated 9/16/15: MPT for new Coles building currently underway.

Traffic Monitoring Plan

Due to the potential for transportation conditions to change over time, NYU will conduct a Traffic Monitoring Program (TMP) to determine the need for and any adjustments to transportation-related mitigation measures.

Traffic Mitigation

NYU will pay the costs of any required traffic mitigation measures (or implement such measures directly) under the direction of DOT, including signal timing changes, widening of the crosswalk at W 4th Street and Washington Square East, and improving the interaction approach at Bleecker and Mercer Streets.

Transit Mitigation

NYU will conduct a study prior to construction of the new Coles and Mercer Buildings to determine the necessity of widening stairs at the Broadway/Lafayette and W 4th Street subway stations. If the stairs must be widened, the work will be completed prior to the issuance of the temporary certificates of occupancy for the Coles Building (for Broadway/Lafayette) and Mercer Building (for W 4th Street).
