Re: Zoning Amendment Petition

Dear Mayor Siddiqui, Vice Mayor Mallon, Ordinance Committee Co-Chair Carlone, Ordinance Committee Co-Chair McGovern, and Councilors Nolan, Simmons, Sobrinho-Wheeler, Toomey, and Zondervan: On behalf of BMR-Third LLC, a subsidiary of BioMed Realty, L.P., we are pleased to submit for your review the enclosed rezoning petition for a proposed amendment to the Zoning Ordinance and the Zoning Map of the City of Cambridge, which, upon adoption, would result in a new Planned Unit Development ("PUD") District CDK.

As you know, we have worked closely with the City to see to the stewardship of what is now branded as Canal District Kendall (formerly Kendall Square and Cambridge Research Park) since completing the acquisition of the former Lyme Properties portfolio in 2007.

Specific stewardship projects include ongoing improvements to the public realm (including renovation of the plaza abutting the Broad Canal, the introduction of public art, improvements to the ice skating rink and boat launch, a commitment to local retail, and the on-going redevelopment and dedication of Termeer Square) and the development of 450 Kendall Street.

We now come to you with what we hope is the final step in finishing what Lyme Properties started in 1999 by realizing on the longstanding goal of having a significant arts and culture facility in the neighborhood. At the same time, we hope to replace the Eversource gas facility located along Third Street to make way for an iconic architectural building that enhances the public realm and the connections among surrounding open spaces.

As you will see in the enclosed proposed Zoning Map amendment, the new overlay district covers the portion of the Canal District Kendall that was originally developed as Kendall EAST 171778189.9 Square plus the Eversource site (referred to here as the gas transfer station site, or "GTS Site," for ease of reference). A. Background.

We submit this petition after soliciting extensive public feedback through community open houses, surveys, deeply engaging with the arts community, and other means to determine what type of arts and culture facility the City wants to see at 585 Third Street. the former Constellation Center site (also known as "Parcel C"). As you know, Consteliation acquired the site in 2002 and spent over 15 years trying to raise the capital for a theater complex at the location.

In the interim, the rest of the area within the proposed PUD- CDK has been improved to now include approximately 757,970 square feet of office and laboratory space, 75,500 square feet of retail and restaurant uses, and 465 residential units. Unfortunately, a standalone theater proved not to be economically viable on Parcel C. We acquired Parcel C in 2018, and have subsequently entered into an option agreement with Eversource that creates the possibility of combining Parcel C with the abutting GIS Site.

The finite duration of the option agreement and the unique ability to relocate the GTS in coordination with a development spanning both parcels makes this a one-in-a-generation opportunity. We continue to work diligently on establishing a new location for the GTS facility, and are nearer than ever to achieving our goal, but have not yet completed that effort.

We and our affiliates are the owners of abutting first class laboratory facilities that serve as key locations for companies like Takeda, Alnylam, and Eli Lilly; the success of development on Parcel C was and is highly important to us and our shareholders. As majority owners in the association that manages the public realm of the Canal District Kendall, the public realm is also essential to us and to our tenants - both biotech and retailers alike.

We are convinced that we can make a significant impact with an arts and culture facility in a way that fits into the neighborhood, is attractive to a diverse set of Cambridge residents and visitors, enhances the public realm, is economically viable, and otherwise furthers the development goals of the community, while being within the guidelines of our mission as a real estate investment company focusing on high quality life sciences space. B. Summary of Petition.

Our zoning petition memorializes the previously approved and constructed density at each site within the proposed PUD-CDK, and allows for additional development on Parcel C and the GTS Site to achieve the project concept described below.

The proposed amendment permits a mixed use development project that is a new building containing an arts, culture, and public space component that complements the existing 465 apartments and commercial space, and, as noted above, creates incentives for incorporating the GTS Site by allowing for greater bulk and height, and public realm amenities, if the GTS Site is included.

The height and floor area, under a scenario where the GTS facility is removed from Third Street, would be 250 feet and up to 550,000 gross square feet, respectively. The proposed amendment does not grant further development potential to the existing buildings constructed within PUD- CDK C. Project Concept. Since acquiring Parcel C, we have worked tirelessly with our consultant team to unlock the full potential of the site. The renderings enclosed show the fruits of our labor.

To accommodate the building and concepts shown, the proposed PUD-CDK allows us to combine Parcel C with the GTS Site and construct mixed use laboratory and office above EASTVI71778189.9 approximately 40,000 square feet of arts, culture, and public space, all in a striking 21 st-century building consistent with existing and other proposed building heights in the vicinity.

This building will significantly enhance the open spaces surrounding it, and will help strengthen the pedestrian corridor that ties together Termeer Square to the north, the Broad Canal and Broad Canal Way retail to the south, and the future Volpe Center project to the west (across Third Street). All of this can be done in a manner that meets the sustainability practices of modern construction and caters to a community as economically and culturally diverse as Cambridge.

Compare the renderings of our proposed project to the existing condition, also shown in the enclosed renderings. Parcel C is the "missing tooth" in the Canal District Kendall, and the location of the GTS Site (the last remnant of an industrial zone on Third Street) exacerbates the problem from an urban planning perspective. We believe that the project facilitated by the enclosed rezoning is a massive improvement, and a welcome addition, to the Cambridge pedestrian environment.
