1.1 PROJECT OVERVIEW 145 BROADWAY STREET

PROJECT SUMMARY

Located at the intersection of Broadway & Galileo Galilei Way within the MXD area, the project at 145 Broadway Street (the "145 Building") is proposed to be a commercial building under the provisions outlined in the City of Cambridge's recently enacted Article 14 Zoning Ordinance. The 145 Building will replace an existing four-story masonry structure currently located on the site which occupies approximately the same footprint as the future project and totals approximately 78,636 SF of gross floor area ("GFA"). The proposed core and shell 145 Building will have a total GFA of approximately 453,768 SF and be up to nineteen floors plus a mechanical penthouse.

The total height of the 145 Building will be up to 250'-0" to the last occupied floor, as defined under zoning. The 145 Building is designed with a +/-12'-8" floor to floor height on typical floors above ground level in order to accommodate commercial office program, ensuring the building's longevity in a rapid ly evolving commercial office market.

The ground floor plan is designed to activate the adjacent public realm to the greatest extent possible, with a publ ic plaza providing direct and open access to the lobby and active use spaces, which extends along Broadway and wraps the corner of Galilee Galilei Way. Ground-level pedestrian circulation along Broadway and the West Service Road allows d irect access and views to the existing open park space. Service and loading is accessed along the northern side of the site, with a dedicated off street loading faci lity for both deliveries and waste management provided at the northeast corner of the building off the western internal drive. Access to vehicular and underground long term bike parking are also located in this area.

The 145 Building will accommodate up to approximately three hundred seventy four (374) vehicular parking spaces and one hundred and fifty-one (151) bike parking spaces in a five (5) story below grade garage, allowing it to serve not only the 145 Building, but also other projects identified as part of this In fill Development Concept Plan.

1.5 ARCHITECTURAL LIGHTING LIGHTING OPPORTUNITIES

a. Amble amount of warm and soft interior light spill from Active Use & Lobby Spaces help to energize the ground level during dusk and evening hours. Special attention to the bottom 20' of the building provides a clearly defined base at night.

b. Emphasize setbacks & vertical breaks to create visual interest and highlight variation that is appropriate to the urban context.

c. Softly graze soffits to emphasize variations in height and architectural elements, which break down the scale and mass of a tall building along a park edge.

d. Expressed Crown at the corner of Broadway and Galileo Way to reinforce a distinct identity for 145 Broadway which is legible from adjacent streets, critical viewpoints, and along the skyline both day and night.
