- Maintenance and Protection of Traffic
Overview: NYU will prepare construction mitigation plans for each new building on the superblocks. Construction mitigation plans will include construction-related environmental commitments such as diesel emission reduction measures, a dust control plan, construction noise reduction measures, construction vibration measures, a construction dewatering plan, a pest management plan, a hazardous materials plan, and a historic resources protection plan. NYU will collaborate with various city and state agencies on this project. For further reference, please review Restrictive Declaration section 4, pages 24 - 41 and Construction Mitigation FAQ for the 181 Mercer Street Project.
Current Status: Construction mitigation plans are in place for the 181 Mercer Street Project and may be updated for different construction phases of the project. Consult the Construction Mitigation FAQ for more information.
Overview: Prior to the start of construction, NYU provided sound-attenuating windows (either new windows or secondary storm windows) and new air conditioners or air conditioner covers for NYU buildings on the superblock site and non-NYU buildings on the periphery of the project site, depending on their proximity to the zone of impact. For further reference, please review Restrictive Declaration section 4.4 (e), page 57.
Current Status: New window and AC or PTAC installation is complete at both WSV and Silver Towers. Off-site noise mitigation for buildings on the periphery of the 181 Mercer Street site that were identified in the Final Environmental Impact Statement as having a significant impact due to construction noise is ongoing.
Overview: NYU will meet noise attenuation requirements for new buildings, including 181 Mercer Street. Noise attenuation involves installing Outdoor-Indoor Transmission Class-rated glass on the building facades. Noise attenuation requirements for 181 Mercer Street will adhere to the Restrictive Dec. sec 4.2 (b), pages 42-43.
Current Status: Noise attenuation planning will be part of the design/construction due diligence process for each building, including 181 Mercer Street.
Overview: NYU will pay the costs of any required traffic mitigation measures (or implement such measures directly) under the direction of the Department of Transportation. For the 181 Mercer Street project, traffic mitigation measures include improving the intersection approach at Bleecker and Mercer Streets. For further reference, please review Restrictive Declaration section 4.4 (d), page 56, and section 4.4 (c), page 54.
Current Status: The identified traffic mitigation for 181 Mercer Street will be implemented prior to completion of the building.
Overview: Due to the potential for transportation conditions to change over time, NYU will conduct a Traffic Monitoring Program to determine the need for and any adjustments to transportation-related mitigation measures. NYU will collaborate with the Department of Transportation on this project. For further reference, please review Restrictive Declaration section 4.4 (c)(iii), page 54.
Current Status: Traffic monitoring will occur after the completion and occupancy of the LaGuardia Building.
Overview: NYU will conduct a study prior to completion of 181 Mercer Street project to determine the necessity of widening stairs at the Broadway/Lafayette subway station. If the subway stair must be widened, the work will be completed prior to the issuance of the temporary certificates of occupancy for 181 Mercer Street. NYU will collaborate with NYC Transit Authority and the Department of City Planning. Refer to Restrictive Dec. sec 4.4(d), page 56 for further reference.
Current Status: The transit stair study is underway.
Overview: NYU will consult with the State Historic Preservation Office regarding aspects of the new construction, including: preparing a Level II HABS documentation of Washington Square Village; a Construction Protection Plan for certain adjacent buildings; and historic plaques and markers in the former Sasaki Garden. For further reference, please review Restrictive Declaration, section 4.4 (b) page 54.
Current Status: This project will be part of the design/construction due diligence process related to the Mercer and LaGuardia buildings.
Overview: NYU will undertake a Phase 1B archaeological investigation in consultation with the Landmarks Preservation Commission to determine the presence of archaeological resources that may exist in areas as denoted in the Final Environmental Impact Statement Figure 7-1A on the superblocks. NYU will also collaborate with the State Historic Preservation Commission on this project on the north block. For further reference please review the Restrictive Declaration section 4 (h) page 36.
Current Status: An area with moderate to high historic period archaeological sensitivity has been identified adjacent to the Bleecker Building development site (sensitive areas were not found in the vicinity of the 181 Mercer Street project site). As part of pre-construction due diligence for the Bleecker Building, NYU will consult with the NYC Landmarks Preservation Commission.
Overview: NYU will prepare a Maintenance and Protection of Traffic (MPT) Plan and provide diagrams of proposed temporary curb lane and sidewalk closures for the 181 Mercer Street project, including the duration of closures, the sidewalk protection measures to be installed for pedestrians, and other MPT items. The Department of Transportation will review and approve NYU’s MPT for the 181 Mercer Street project. For further reference, please refer to Restrictive Declaration section 4.1 (i), page 41.
Current Status: MPT plans for initial construction phases of 181 Mercer Street are approved by DOT. See the site plan for street and lane closures.
