MHNHS Parcel 25 Development

SERVICE:

Air Quality and Sound Analyses

DESCRIPTION:

Tech performed air quality and noise analyses as well as a greenhouse gas (GHG) study to satisfy the BRA Article 80 Expanded PNF and the Expanded Environmental Notification Form (EENF) for the Mission Hill Parcel 25 Project. The Project involves development for a mixed-use, residential, retail and commercial development of approximately 305,750 gsf, to be developed in three phases, which will include at full build-out: 98,000 gsf of residential space (88 apartment units), 10,000 gsf of retail, 1,250 gsf of community space, and up to 196,500 gsf of office. Additionally the full build-out of the Project will contain up to 201 surface and below-grade structured parking spaces. Tech performed baseline sound monitoring, noise modeling of the rooftop equipment, and an air quality analysis on the proposed parking garage. In addition to the work listed, Tech performed a carbon monoxide (CO) microscale analysis for three intersections. All modeling results and analyses demonstrated compliance with federal, state and local standards. The GHG study demonstrated that the building design will be able to achieve a 22 percent reduction in GHG emissions.
