CITY OF CAMBRIDGE, MASSACHUSETTS P L A N N I N G B O A R D CITY HALL ANNEX, 344 BROADWAY, CAMBRIDGE, MA 02139 Page 1 of 3 Date: Wednesday, May 27, 2015 Subject: PUD-KS Rezoning Petition To the Honorable, the City Council, Submitted herein is a zoning petition to amend the provisions of the PUD-KS District set forth in Section 13.10 of the Zoning Ordinance. The intent of these proposed changes is to implement the zoning recommendations of the Kendall Square (“K2”) Planning Study in order to facilitate future redevelopment of the John A. Volpe Transportation Systems Center site, which occupies the majority of the PUD-KS District, in accordance with that study. The proposed zoning retains the current boundaries of the PUD-KS District (see attached maps) and retains the current Planned Unit Development (PUD) zoning structure that would permit new development according to a master plan requiring public review and approval by the Planning Board. The petition proposes the following changes to advance the recommendations of the K2 study.  Increase allowed development capacity and height to achieve development of the density and scale anticipated in the K2 study.  Retain existing mixed-use requirement, with at least 40% of private development in a PUD devoted to housing.  Establish maximum rather than minimum parking requirements and encourage shared parking facilities in order to reduce the amount of new parking created, discouraging automobile traffic and encouraging sustainable modes of transportation.  Require retail and other active ground floor space along major streets, with incentives for small retail spaces throughout a PUD.  Require “innovation space” as a component of all new office development, with shared spaces and facilities designed to serve small companies and start-ups.  Enhance sustainable design, including a requirement to design to a LEED Gold standard with a focus on energy-related measures, meet stormwater management objectives, employ cool roofs, investigate district energy and on-site energy solutions, and consider urban heat island mitigation and climate change adaptation as part of building and site design.

The proposed change would require, at a minimum, one quarter of a development parcel to be public open space whose location and design would be reviewed through the PUD process. City plans and guidelines, including open space framework and principles being developed through the Connect Kendall Square process, would inform that future review.  Require funding contributions from new commercial development to support area-wide open space programming, transit improvements and workforce development. Another aspect of the proposed zoning change is meant to enable a redevelopment plan that incorporates the creation of a new government facility to house the Volpe Center. The zoning proposal includes provisions that clarify how a Federal government facility would be treated as part of a PUD. Because it is beneficial to include such a facility as an integral part of a development master plan, the proposal exempts such a facility from requirements to which it would already be immune. Federal government uses are immune from local regulations, which would nonetheless apply to private development on the site. In a process that parallels this rezoning initiative, the U.S. General Services Administration (GSA) and U.S. Department of Transportation (DOT) are undertaking a process to select a private development partner to construct a new Volpe Center facility on a portion of the site and redevelop the remainder of the site for private use according to the City’s zoning. Given that this is truly a once in a generation opportunity to encourage change on this site, it is crucial that the final zoning enables private development that is capable of supporting the needs of the Federal agencies who control the land while meeting the City’s planning objectives. GSA and DOT have been engaged in the rezoning process and have informed discussions with the Board, staff and the public. There are some additional aspects of this zoning petition that go beyond the recommendations in the K2 study. These differences are based on objectives that have been discussed and emphasized since the completion of the K2 study, and which the Board believes are worthy of the Council’s consideration.  For a PUD project the petition proposes eliminating the standard inclusionary housing structure of a “base” requirement and an additional “bonus,” and instead requiring 10% of total housing to be affordable and available to low and moderate income households and 5% of total housing to be affordable and available to middle income households. The proposed requirement is based on minimum square footage rather than units, in order to encourage affordable units of larger sizes. To offset the removal of the “bonus,” the base FAR limit is increased to 4.5, which results in approximately the same total amount of private development as envisioned in the K2 study. The Board had extensive discussion about the specific percentages of low-moderate and middle income housing requirements for a PUD. A range of ideas up to a total of 20%,

City of Cambridge, MA • Planning Board Communication PUD-KS District Rezoning Petition (Volpe Center Site) May 27, 2015 Page 3 of 3 rather than the current 15%, were discussed. While all members would like to see the maximum amount of affordable housing accommodated in the district, the majority of Board members support a minimum requirement of 15% total subsidized housing in recognition of the special constraints posed by the Federal ownership and equity transaction envisioned for a redevelopment plan.  The K2 study recommends 250 feet as a maximum height for commercial buildings and 300 feet for residential. The petition also proposes allowing the Board to consider a limited number of buildings in the section closest to Broadway to reach 350 feet, and potentially one building of even greater height, up to 500 feet. The Board believes that it is worth considering whether this district is uniquely suited to a signature landmark building that exceeds the prevailing height of surrounding buildings. To approve a building at such a height, the Board would need to verify through the PUD approval process that it meets a high standard for architectural excellence. The Board looks forward to the Council’s referral of this petition for public hearings, where Board members, staff and the public can discuss the broad objectives and the particular provisions of the proposal in greater depth. Respectfully submitted for the Planning Board, H Theodore Cohen, Chair. Attachments Zoning Petition (clean version) Text Changes to Section 13.10 (with edits shown)

The PUD-KS district is intended to provide for the creation of a vibrant mixed-use district of high quality general and technical office and retail activity, with a significant components of residential use and open space. The retention of government office facilities on the site is desired, as well as space for smaller innovation companies as a component of the commercial office space that is created. The creation of public open space to serve residents of the district and the larger neighborhood, as well as workers, students from nearby institutions and visitors, a large public park is desired. The PUD-KS district permits larger scale development and supporting commercial activities close to Kendall Square and the major public transit services located there. It encourages strong linkages between new development at Kendall Square, the East Cambridge riverfront, and the PUD-KS area and the neighborhoods of eastern Cambridge, facilitated in part by a strong and continuous retail presence along Third Street and Broadway. Development in the PUD-KS district is expected to meet high standards for urban design, environmental sustainability and open space design and should be generally consistent with the policy objectives set forth in the Kendall Square Final Report 2013 (K2 Plan) Eastern Cambridge Plan and the guidance provided in with the Eastern Cambridge Kendall Square Design Guidelines. 13.11.1 Master Plan Area. To further the purpose of this Section 13.10, any Development Parcel or portion of a Development Parcel meeting the requirements set forth in Section 13.13.2 below and that is at least five (5) acres in area may be designated as a Master Plan Area, within which physical information shall be presented in a more generalized way, subject to more detailed approval by the Planning Board at a time and in a manner determined by the Board in its PUD special permit decision. 13.11.2 Master Plan Requirements. At a minimum, a Development Proposal for a Master Plan Area must contain the following components: a. Site Development Plan – identifying each of the proposed existing and new building sites within the Master Plan Area and the characteristics of each, including potential uses and Gross Floor Area. b. Site Massing Plan – illustrating the height and massing of building volumes for each proposed building site, and including studies of anticipated shadow and wind impacts resulting from building mass. The purpose is modified somewhat  to reflect the current goals  articulated in the K2 study, which  are nevertheless similar to those in  the prior Eastern Cambridge (ECaPS)  Plan. In addition, the purpose  supports retaining Federal facilities,  while the zoning is structured to  recognize that Federal facilities  would, under normal circumstances,  be immune from local regulation.  A provision for PUD Master Plan  approval (which is also in the North  Point PUD zoning) is included. It  describes the elements of a PUD  Master Plan and the criteria and  process for approval. Given the  urban design goals of the area to  create connectivity and open space,  the PUD Master Plan review will be  a critical part of the planning  process.

Parking and Loading Plan – identifying the locations of all parking facilities, bicycle parking facilities and facilities for loading or other vehicular service functions, and the number of spaces proposed at each location. d. Connectivity Plan – illustrating all pedestrian, bicycle and vehicular circulation routes within the Master Plan Area, their connections to public circulation routes and destinations outside the Master Plan Area, and approximate locations of access and egress points on each building and parking facility within the Master Plan Area. e. Open Space Plan – illustrating and quantifying the areas of all proposed open space and the ownership and designation of each area (e.g., Public Open Space, Publicly Beneficial Open Space) as well as descriptions of major design elements and themes to be incorporated into each space and the types of uses and activities that will be accommodated in each space. f. Ground Floors Plan – illustrating the conceptual arrangement of functions such as retail establishments and other active uses, residential and office lobbies, and utility spaces at the ground floor of each building in the Master Plan Area, including the locations and sizes of retail and other active uses that may be required or incentivized by the specific provisions of this Section 13.10. g. Housing Plan – providing the approximate number and mix of housing unit types proposed on each residential site, and identifying the location of dwelling units that may be required or incentivized by specific provisions of this Section 13.10. h. Phasing Plan – describing the general sequence in which development is proposed to proceed, and specifically describing how the phasing requirements set forth in this Section 13.10 will be met. 13.11.3 Master Plan Approval. The Planning Board shall grant a PUD special permit for a Master Plan Area upon finding that the Final Development Plan is consistent with the criteria set forth below, in addition to all other criteria applicable to approval of a Final Development Plan and any other special permits being sought, and upon consideration of the K2 Plan, Kendall Square Design Guidelines, PUD-KS Site Planning and Design Guidelines and other City plans and guidelines applicable to Kendall Square.

Otherwise, any modifications to a Final Development Plan for a Master Plan Area shall be considered pursuant to the PUD Amendment provisions set forth in Section 12.37 of this Zoning Ordinance. 13.11.4 Master Plan Criteria. A Final Development Plan for a Master Plan Area shall meet the following objectives, subject to approval by the Planning Board: (1) Providing a mix of commercial, including research and technology, and residential uses, with particular emphasis on housing and ground-floor retail, to encourage activity throughout the day and evening.

In the PUD-KS District the maximum ratio of floor area to Development Parcel shall be 3.0 4.5, subject to the further use limitations set forth below in Section 13.13.11. For the purposes of calculating FAR, the GFA of the following uses shall be exempt from the requirements of this Section 13.13.1: (1) GFA devoted exclusively to a use designated as Other Government Facility in the Table of Use Regulations on a Government Owned Lot, as set forth in the provisions of Section 13.113 below. Notwithstanding such exemption, a Government Owned Lot can be included in calculating the area of a Development Parcel. (2) GFA devoted to retail and consumer service uses, provided the GFA is located on the ground floor or basement level, is clearly identified within the Active Use Plan as described in Section 13.112.1 below (though the exempt GFA may exceed the required Active Use), fronts on and has a public entrance onto a public street, park, or plaza, and for each individual establishment the GFA does not exceed 5,000 square feet. The Planning Board may approve such an exemption for a space of a larger size if it is devoted to a particular type of retail that is desired in the neighborhood but requires a larger space to be feasible. (3) Fifty (50) percent of the GFA devoted to innovation office space, up to a maximum of five (5) percent of non-residential GFA in a Final Development Plan, as described in Section 13.112.3.3 below. 13.13.1.1 Limitations on Non-Residential Development. In the PUD-KS District all non-residential uses shall be further limited as set forth below. Where the amount of non-residential GFA is limited to a percentage of the total GFA authorized, the calculation shall be based on GFA authorized exclusive of any GFA that may be constructed as a result of the application of the FAR bonuses permitted in Section 11.200 or any GFA devoted exclusively to structured parking. (1) For any lot or combination of lots held in common ownership as of June 1, 2001 having in total an area of less than five acres, the total GFA devoted to non-residential uses shall not exceed ten (10) percent of the total GFA authorized in a PUD for that portion of a PUD Development Parcel containing such lot or lots, or any portion thereof. This limitation shall apply to each Development Parcel individually. This limitation shall not apply to any individual lot created subsequent to the Planning Board’s approval of the PUD Final Development Plan. The increased FAR and exemptions  are in accordance with the  recommendations of the K2 study.  The base FAR is set at 4.5 rather  than 4.0 because the “inclusionary  bonus” is removed below to simplify  the affordable housing calculation.  This text is removed because the  FAR bonus for affordable housing is  removed further below.

(2) For any lot or combination of lots held in common ownership as of June 1, 2001 having in total an area of more than five (5) acres, the total GFA devoted to non-residential uses shall not exceed sixty (60) percent of total GFA authorized, exclusive of GFA exempted in Section 13.13.1 above, inclusive of any GFA otherwise exempt from the provisions of the Cambridge Zoning Ordinance in a PUD for that portion of a PUD Development Parcel containing such lot or lots, or any portion thereof. This limitation shall not apply to any individual lot created subsequent to the Planning Board approval of the PUD Final Development Plan. The limitations set forth in this Section 13.13.1.1(2) shall not apply to any individual lot within a Development Parcel created subsequent to the Planning Board approval of the PUD Final Development Plan. The Final Development Plan shall include a Phasing Plan providing a general sequence for the construction of residential and non-residential uses. The Planning Board shall approve such a Phasing Plan if it is found to ensure that residential uses will be completed on a schedule that meets the objectives of the City and ensures compliance with the requirements of this Paragraph (2). In general, non-residential development shall not be authorized to exceed sixty percent (60%) of the total non-exempt GFA permitted for non-residential uses until substantial construction activity of residential uses has commenced. Full completion of the permitted non-residential GFA shall not be allowed before the full permitted residential development has been completed or substantial construction activity has commenced. The Planning Board may approve variations to the standards in this Paragraph if the Phasing Plan is found to be in general conformance with the intent of this Paragraph. 13.13.1.2 Special Affordable Housing Provisions. For any lot or combination of lots held in common ownership as of June 1, 2001 having in total an area of more than five (5) acres, the following requirements shall apply in place of the Inclusionary Housing requirements set forth in Section 11.200 of this Zoning Ordinance. a. Notwithstanding anything to the contrary in this Ordinance, no less than ten percent (10%) of the total floor area devoted to private residential dwelling units shall be devoted to Affordable Units in accordance with the definitions and Required residential development is  kept at the same percentage as  recommended in the K2 Plan.  Standards for phasing are added.  In addition, the typical Inclusionary  Housing requirements are  superseded by a required  percentage of Affordable (low‐to‐ moderate income) and Middle‐ Income residential space that does  not result in an additional floor area  bonus. Because no bonus is  provided, the requirement (as a  percentage of total housing)  exceeds the amount of affordable  housing required under current  zoning. However, in recognition of  the desire to provide larger‐sized  affordable units, the requirement is  conceived as a percentage of floor  area rather than a number of units.

Such Affordable Units shall be distributed evenly throughout all residential buildings within the PUD. b. In addition to the Affordable Units specified in Paragraph (a) above, no less than five percent (5%) of the total floor area devoted to private residential dwelling units shall be devoted to Middle Income Units. In a Master Plan Area, such Middle Income Units may be located in one or more residential buildings, provided that buildings containing Middle Income Units are identified in the Housing Plan and Phasing Plan. For the purposes of this Section 13.13.12, Middle Income Units shall be defined as residential dwelling units for which: i. the occupancy is restricted to households whose total income exceeds eighty percent (80%) but does not exceed one hundred twenty percent (120%) of the median income of households in the Boston Standard Metropolitan Statistical Area adjusted for family size, or such other equivalent income standard as may be determined by the Board of Trustees of the Affordable Housing Trust Fund; and ii. the rent (including utilities) does not exceed thirty percent (30%) of the income of the renting household or, in the instance of home ownership units, the monthly mortgage payment (including insurance, utilities and real estate taxes) does not exceed thirty percent (30%) of the income of the purchasing household, or such other equivalent standard as may be determined by the Board of Trustees of the Affordable Housing Trust Fund. c. In general, Affordable Units and Middle Income Units shall be provided in accordance with the Standards for Construction and Occupancy set forth in Section 11.204 of this Zoning Ordinance. As an exception, to serve the objective of providing additional two-bedroom and three-bedroom units suitable for families with children, the Planning Board may approve a Final Development Plan providing Affordable Units and Middle Income Units that are, on average, larger in area than the other dwelling units in the building. Where such units are larger in size, they may be accordingly fewer in number, provided that the requirements in Paragraph (a) and (b) are met. Nevertheless, Affordable Units and Middle Income Units shall be reasonably distributed throughout a building and may not have different interior or exterior finishes from other units, and occupants shall have access to common amenities available to other residents of the building. For a Master Plan Area, the Housing Plan component of a Development Proposal must indicate the approximate

Notwithstanding the provisions of Section 11.203.2 of the Inclusionary Housing requirements, no increase in Floor Area Ratio or Gross Floor Area beyond the limitations set forth in Section 13.13.1 shall be provided for a PUD subject to the requirements of this Section 13.13.1.2. e. Notwithstanding paragraphs (a) through (d) above, if the Inclusionary Housing requirements applicable citywide are amended subsequent to June 1, 2015 such that more than fifteen percent (15%) of the total floor area devoted to residential units must be devoted to Affordable Units or Middle Income Units, then those citywide Inclusionary Housing requirements shall supersede the requirements of this Section 13.13.1.2. Notwithstanding the above limitations, additional non-residential GFA shall be permitted as set forth in Paragraph (3) below. At least ninety-five (95) percent of the authorized non-residential GFA must be located on the portion of said lot or lots having an Office 2 base district designation. However, where circumstances related to the transfer of property from the federal government to other governmental or private entities (for the purpose of private development on a portion or all of the land in the control of the federal government) the Planning Board may in its discretion approve a Final Development Plan providing GFA in excess of sixty (60) percent of the authorized GFA in the PUD provided it is conclusively demonstrated to the Planning Board that all residential GFA required to be developed on such lot or lots in their entirety, by this Paragraph, has already been constructed. (3) For the entire PUD-KS district, the first 50,000 square feet of retail and customer service uses authorized in total in all approved PUDs shall not be counted toward the non-residential GFA limitations of Paragraphs (1) and (2) above provided the GFA is located on the ground floor of a multistory building, fronts on and has a public entrance onto Third Street, Broadway, or a public park, and for each individual establishment the GFA does not exceed 10,000 square feet.

The minimum size of a Development Parcel within the PUD-KS shall be the greater of (1) 40,000 square feet or (2) seventy-five percent of the area of a lot or combination of lots (a) in existence as of June 1, 2001 and (b) held in common ownership where it is proposed to incorporate any portion of such lot or lots within the Development Parcel. A Development Parcel within the PUD-KS may contain noncontiguous lots elsewhere in the PUD-KS district or within a contiguous PUD district. There shall be no specified minimum lot size for lots located within a Development Parcel. However, where circumstances related to the transfer of property from the federal government to other governmental or private entities (for the purpose of private development on a portion or all of the land in the control of the federal government) limit the feasibility of creating a Development Parcel meeting the size requirements of this Section 13.13.2, the Planning Board may in its discretion approve a PUD application having a smaller Development Parcel size. 13.13.3 Residential Density. For the purpose of computing residential density, the minimum lot size for each dwelling unit shall be three hundred (300) square feet. Residential density shall be computed based on the entire development parcel. There shall be no required minimum Lot Area Per Dwelling Unit in the PUD-KS District. 13.13.4 Maximum Building Height. 13.13.4.1 The maximum height permitted in the district shall be sixty-five (65) two hundred fifty (250) feet except as it may be further limited or permitted below. The permitted heights are further illustrated on the Building Height Regulation Map for the PUD-KS, Map 13.11. (1) Reduced Building Height to One Hundred Forty Feet. The maximum height shall be reduced to one hundred forty (140) feet in portions of the PUD-KS District within one hundred fifty (150) feet of the centerline of Binney Street. (2) Reduced Building Height to Eighty-Five Feet. The maximum height shall be further reduced to eighty-five (85) feet in the portion of the PUD-KS District bounded by the centerline of Binney Street, the centerline of Third Street, a line four hundred twenty-five (425) feet north of and parallel to the centerline of Broadway, and a line seventy-five (75) feet west of and parallel to the centerline of Fifth Street, including the extension of such lines to their intersection with other reference lines identified in this Paragraph. The K2 study recommends removing  limits on unit density to allow for a  variety of unit types and sizes,  including micro‐units. Height limits are modified to  establish a base height of 250 feet  (as in the adjacent MXD District),  with reductions to 85 feet in areas  adjacent to existing housing of that  scale, reductions to 140 feet  elsewhere along Binney Street, and  the option to increase height to 350  feet in the section closest to  Broadway, and to allow no more  than one building that may be even  taller (with a strict limit of 500 feet).  See map for reference.

In the portion of the district within a distance of four hundred twenty-five (425) feet from the centerline of Broadway, the Planning Board may approve one building that is of exceptional architectural quality to exceed two hundred fifty (250) feet but not to exceed five hundred (500) feet, and other buildings to exceed two hundred fifty (250) feet but not to exceed three hundred fifty (350) feet, provided that no more than twenty percent (20%) of the area of that portion of the district may be covered by buildings or parts of buildings exceeding two hundred fifty (250) feet in height. Additional Building Height to Eighty-Five Feet. The maximum height shall be eighty-five (85) feet in the areas described below: (a) An area bounded by the centerlines of Fifth Street, Monroe Street, Third Street and Potter Street. (b) An area bounded by the centerline of Potter Street and its northwesterly extension; then the centerline of the former Sixth Street (the MXD district boundary line); then a line northeasterly of, parallel to and two hundred (200) feet distant from the northeasterly sideline of Broadway; then a line northwesterly of, parallel to, and three hundred (300) feet distant from the northwesterly sideline of Third Street, to the point of beginning. (2) Additional Building Height to One Hundred and Twenty Feet. The maximum height shall be one hundred and twenty (120) feet in that area bounded by areas described in Paragraph (1) above; then the centerline of Third Street; then a line northeasterly of, parallel to, and one hundred (100) distant from the northeasterly sideline of Broadway; then the centerline of the former Sixth Street (the MXD district boundary line) to the point of beginning. (3) Additional Building Height to One Hundred and Eighty Feet with Portions to Two Hundred and Fifty Feet. The maximum height shall be one hundred and eighty (180) feet in that area bounded by the area described in Paragraph (2) above; then the centerline of Third Street; then the centerline of Broadway; and then the centerline of the former Sixth Street (the MXD district boundary line) to the point of beginning. However, portions of buildings may rise above one hundred and eighty (180) feet to no more than two hundred and fifty (250) feet provided the area of all floorplates of portions of buildings above 180 feet do not exceed ten percent of the total area of the Development Parcel.

Notwithstanding the provisions of Paragraphs (1) – (3) above, any portion of a building that is within fifty (50) feet of an existing or proposed Public Open Space or single intervening street abutting that open space may exceed 45 feet only if for each floor above 45 feet, that floor is set back an additional 10 feet from the façade of the floor below, until the maximum height is attained, or until a 20 foot setback from the façade at 45 feet is attained. Alternately, a set back of 20 feet from the façade of the building at a height of 45 feet shall be permitted, and the remaining portions of the building allowed to achieve the maximum height permitted in Paragraphs (1) – (3) above or any variation between the two provisions. 13.13.42 The Planning Board shall not approve any Final Development Plan in the PUD-KS District not in conformance with the regulations of Section 13.13.4 above. In the portion of the PUD-KS that allows buildings to 200 feet or more, the Planning Board may approve a building up to 250 feet if other buildings or portions of buildings in that portion of the Development Parcel are no higher than one hundred and fifty (150) feet. 13.13.43.2 In evaluating a development proposalDevelopment Proposal and/or a Site Massing Plan for a Master Plan Area providing building height in excess of one hundred and twenty (120) one hundred twenty-five (125) feet, the Planning Board shall give consideration to evidence presented on the following: (a) that increased height is located on the site and designed in such a way to reduce the impact of shadows, excessive wind, and obstruction of light and views, with specific consideration given to residential buildings and public spaces will not cast shadows or alter air currents in ways that will unreasonably limit the amount of light and air reaching other buildings in the vicinity to a significantly greater extent than if the building height did not exceed one hundred and twenty (120) feet; (b) that increased height would mitigate detrimental environmental impacts such as excessive ground coverage, diminution of open space, and monotonous development; (c) that increased height would not adversely affect and would result in increased sensitivity to the visual and physical characteristics of the particular location be sensitively managed to provide an appropriate scale at interfaces with adjoining lower scale uses, such as through more harmonious relationships to the terrain and to the proposed and existing buildings and open spaces in the vicinity that have functional or visual relationships to the proposed building; The criteria for height review are  changed somewhat to be more  consistent with the vision of the K2  Plan and the Kendall Square Design  Guidelines.

The(d) if applicable, the additional height permits accommodation of GFA transferred from the Eastern Cambridge Development Rights Transfer Donating District. Notwithstanding the provisions of Paragraphs (a) through (d) above, the Planning Board shall give consideration to the consistency of any Final Development Plan in achieving the design and site planning goals, as well as the measures set out to achieve these goals, as set forth in the Kendall Square Design Guidelines. 13.13.5 Other Dimensional Requirements. There shall be no minimum width for the Ddevelopment Pparcel and no minimum width for lots located within the Ddevelopment Pparcel. There shall be no minimum required front, rear and side yard requirements for a Ddevelopment Pparcel or for lots located within a Ddevelopment Pparcel. The Planning Board shall approve all such lot sizes and building setbacks. 13.14 Open Space. The following Open Space requirements shall be met on each Development Parcel. (1) For that portion of a Development Parcel consisting of lots described in Section 13.13.1.1, Paragraph (1) above, any combination of Public Open Space, Green Area Open Space or Permeable Open Space, as defined in this Ordinance, shall be provided on the Development Parcel and shall in the aggregate equal at least twenty (20) percent of the area of that portion of the Development Parcel. (2) For that portion of a Development Parcel or Master Plan Area consisting of lots described in Section 13.13.1.1, Paragraph (2) above, any combination of Public Open Space, Green Area Open Space or Permeable Open Space, as defined in this Ordinance, shall be provided on the Development Parcel and shall in the aggregate equal at least Forty-two (42) twenty- five (25) percent of the area of that portion of the Development Parcel, subject to the further limitations set forth in Section 13.14.1 below. For the purpose of this Section 13.10, Open Space on a Government Owned Lot in accordance with Section 13.113 shall be For larger development parcels (i.e.,  the Volpe parcel), the current  complex and onerous open space  requirements are replaced with a  simple requirement that at least  25% of the development parcel be  public open space as currently  defined in the Zoning Ordinance.  This would remain the highest open  space requirement for any large  development area in the city, and  would result in at least 3.5 acres of  public open space being created if  the site is redeveloped.

Owners of adjacent Development Parcels may collectively provide the required open space by easement, deed restriction, covenant, or comparable legal instrument enforceable by the City of Cambridge or other public entity provided the Planning Board finds that the owners of each Development Parcel have provided written evidence of an agreement that the total amount of open space required for both Development Parcels is provided and that the Open Space Plans for each Development Parcel meet the standards for approval. In that event, the Planning Board shall record in the Special Permits for each PUD the amount of open space required on each Development Parcel each Development Parcel shall, for purposes of this Section 13.10 be deemed to include that portion of such open space as the owners shall allocate to it in chosen legal instrument. All required open space shall be generally accessible to the public for reasonable periods throughout the day for the purposes for which the open space is designed and approved by the Planning Board, which may include but not be limited to walking, bicycling, active and passive recreation. The Planning Board must approve any proposal to significantly limit public access to the required open space. 13.14.1 Required Public Open Space. For that open space required in Section 13.14, Paragraph (2) above, the required open space shall consist in part of a contiguous 7.5 acre Public Open Space to be located in the northwest quadrant of the PUD-KS district as further described and located in the Eastern Cambridge Plan. The Public Open Space shall be under the control of the City of Cambridge through fee simple conveyance, easement, or other legal mechanism acceptable to the City. In the event that the City of Cambridge does not accept the facility, the PUD permittee shall maintain the park for the use of the general public as originally designed and approved by the Planning Board in the Special Permit. The Public Open Space shall be designed and constructed by the permittee according to the conditions of the PUD special Permit and when conveyed to the City shall be environmentally and otherwise suitable for the recreational uses for which it is designed. However, where circumstances related to the transfer of property from the federal government to other governmental or private entities (for the purpose of private development on a portion or all of the land in the control of the federal government) limit the feasibility of creation of a 7.5 acre park, the Planning Board may at its discretion approve a Final Development Plan providing a contiguous Public Open Space of less than 7.5 acres.

(a) For the purpose of this Section 13.113, a Government Owned Lot shall mean a lot owned by the federal government that may be developed in conjunction with a transfer of land to a private entity, where such transferred land abuts the Government Owned Lot, and where, for the convenience of the government, the Government Owned Lot is included as part of a Development Parcel or Master Plan Area. If so included, such Government Owned Lot shall be clearly identified in a Development Proposal and Final Development Plan. (b) Uses on a Government Owned Lot categorized as Other Government Facility in Section 4.33, item (g) in the Table of Use Regulations in this Zoning Ordinance, if included within a Final Development Plan, shall be exempt from the requirements set forth in this Section 13.113 and elsewhere in the Ordinance, including but not limited to Floor Area Ratio (FAR) limitations, limitations on non-residential use allowed in a Final Development Plan, Active Use requirements, Innovation Space requirements, Community Fund contributions and Incentive Zoning contributions. (c) Notwithstanding the above, a Government Owned Lot shall be included in calculating the area of a Development Parcel for all purposes, including the calculation of FAR limitations and Open Space requirements. Public Open Space on a Government Owned Lot may be counted toward meeting the open space requirements of Section 13.14, regardless of any temporary limitations on access or use that may be imposed by the controlling government entity. (d) If a Special Permit has been granted authorizing development on a Development Parcel or Master Plan Area containing a Government Owned Lot in accordance with a Final Development Plan, and the controlling government entity later separates the Government Owned Lot from the remainder of the Development Parcel or Master Plan Area, then no future modification to development on the Government Owned Lot shall affect the development authorized in the approved Final Development Plan on the remainder of the Development Parcel or Master Plan Area, and such development shall be allowed to proceed in accordance with the Final Development Plan. These provisions are included  acknowledging that the  development of Federal facilities  would, under normal circumstances,  be immune from local regulation.  There would be a benefit to  including such facilities in a PUD  plan rather than having them  developed separately on a stand‐ alone site. This text seeks to remove  requirements that may be seen as  impediments by a Federal agency, to  incentivize development of  government facilities within a PUD  area.
