FORWARD TO PLAN AMENDMENTS 10 AND 11 REGARDING THE RE-STATED KENDALL SQUARE URBAN RENEWALREDEVELOPMENT PLAN In the nearly forty years since the adoption of Amendment 1 to the Kendall Square Urban Renewal Plan (Plan), the Cambridge Redevelopment Authority (CRA) has adopted many changes to the Plan in response to the dynamic development environment in Cambridge. The execution of the Plan within the Project Area has been a key catalyst to the overall transformation of the Kendall Square neighborhood. The emergence of Kendall Square as a center of innovation, creativity and technology has exceeded the expectation of the planners, designers, and developers who first drafted the Plan in 1977. The CRA adopted Amendment 10 in December 2015, in order to aim to reflect these changes and to chart a way forward in furtherance of the recommendations from the 2013 K2 Planning Study. The update of the Plan’s objectives reflected not only the important work of bringing jobs to Kendall Square, but also the larger goal of creating a sustainable, inviting, and inclusive neighborhood. As in prior adopted amendments, the proposed a Amendment No. 10 increases increased the development limits to reflect the continued demand for commercial and laboratory space, with an emphasis on bringing additional housing and retail to the Project Area. New provisions will assist the CRA in linking transit investment to development, aiming to ensure that the Project Area’s transit assets grow along with it. Provisions for innovation space and affordable housing are were included so that Kendall Square remains not only a destination for the great thinkers of today, but also a laboratory for the great ideas of tomorrow and a great urban neighborhood for Cambridge. The Plan under Amendment 10 was re-stated, not remade anew. Consequently, some sections - such as those discussing land clearance - addressed matters already undertaken, and have been were modified accordingly to reflect things that happened in the past. This is was by design as the document is meant not only to guide Kendall Square’s development in the future, but also to tell the story of its past. For this reason, bracketed numbers appearing at the ends of paragraphs throughout the Plan indicate where language has been changed, and sometimes changed again and again. The bracketed numbers identify which plan amendment facilitated the revisions. The CRA is proposing Amendment 11 to the Plan for two reasons. The first is to accommodate the relocation of a planned electrical substation within the MXD District. This site would move the infrastructure facility out of the residential neighborhoods along Fulkerson Street to the location of an existing above ground parking garage. There are many complex technical and financial challenges associated with relocating the substation to this parcel. The proposed MXD site involves not only the design of the substation and high voltage access routes to the location, but also completing plans for the housing program outlined in the current Infill Development Concept Plan, fulfilling interim and future parking requirements, and designing locations for additional development to provide financial support for this alternative location. The second reason to undertake this Amendment 11 is to rename the Kendall Square Urban Renewal Plan the Kendall Square Urban Redevelopment Plan (sometimes referred to in this Amendment as the “Plan.”). The reason for this proposed title change is to recognize that the

urban renewal programs of redevelopment authorities throughout the country have had a disproportionate impact on communities of color, and in many cases implemented overtly racist urban policies. While the redevelopment of Kendall Square involved mostly industrial and commercial land, approximately ten households were relocated from the project area through the federally sponsored urban renewal program. Although there is no evidence of outward racism in the implementation of the plan, the CRA wishes to acknowledge the historic and cumulative impact of our nation’s urban renewal programs, particularly on Black communities. Moving forward, the CRA is committed to improving our community engagement to amplify the voices of communities of color, and by implementing projects and programs that provide economic opportunities, quality of life improvements and other equity focused outcomes, and that serve communities of color, both within Kendall Square and throughout the surrounding neighborhoods. Amendment 11 follows the same approach toward restating the Plan text as Amendment 10 did five years ago. The proposed language changes of Amendment 11 are designated with underlined and strikethrough text. Formatting updates and clarifications of defined terms are not highlighted or numbered. The term “urban renewal” is replaced throughout the Plan, except where there is a specific reference to historic activities under the state and federal programs at the time.

Kendall Square Urban Redevelopment Plan page 1 1.28.21 CHAPTER 1: DESCRIPTION OF PROJECT ________________________________________________________________ This document, prepared by the Cambridge Redevelopment Authority (CRA), sets forth a plan for urban renewal action in the so-called Kendall Square Area of Cambridge, in accordance with the terms of Section 48 and other applicable provisions of Chapter 121B of the Massachusetts General Laws, and with the provisions of the U.S. Housing Act of 1949 as amended. Section 101: Boundaries of the Project Area The project is situated in an area bounded generally by Main Street, the land or right of way now or formerly of the Boston and Albany (Grand Junction) Branch Railroad, Binney Street, and Third Street. A description of the perimeter boundary of the project area is attached hereto as Exhibit A of the Urban Renewal Urban Redevelopment Plan and is made a part hereof as if fully set forth herein. [11] The perimeter boundary of the project area is shown on Map 1: Proposed Land Use Plan, which is attached hereto as Exhibit B of the Urban Renewal Urban Redevelopment Plan and made a part hereof as if fully set forth herein. [11] As shown on Map l Proposed Land Use Plan, that portion of the project area which has not been conveyed to the United States of America (and which is bounded generally by Binney Street on the North, the Boston and Albany (Grand Junction) Branch Railroad on the west, Main Street on the South and discontinued Sixth Street and Broadway on the East) is hereinafter described as the “MXD District” or “MXD District portion” and the remaining portion of the Project Area is hereinafter described as the “remainder of the project area.”[10] Section 102: Urban Renewal Redevelopment Plan Objectives The Urban Renewal Urban Redevelopment Plan objectives of the project are as follows: [11] (a) To secure the elimination and prevent the recurrence of blighted, deteriorated, deteriorating, or decadent conditions in the project area; (b) To insure the replacement of such conditions by well-planned, well-designed improvements which provide for the most appropriate reuse of the land in conformity with the general plan for the City of Cambridge (the “City”) as a whole and with definite local objectives, which objectives are: 1. The provision of land uses which maximize job opportunities at a variety of skill levels within Kendall Square’s knowledge and innovation based economy, including blue-collar and non-professional white-collar employment, for present and future Cambridge residents; upgrade Cambridge workers' skills and wages in a manner

Kendall Square Urban Redevelopment Plan page 2 1.28.21 commensurate with the cost of living in Cambridge; and help stabilize the City's economic base and maximize the provision of local jobs; [10] 2.

Subsequent plan amendments have revised the dimensional requirements for the lands both acquired and cleared by the CRA, but have not expanded those land clearance activities. References to those activities are preserved in the document for historic reference. [11]

Kendall Square Urban Redevelopment Plan page 14 1.28.21 Section 402: Dimensional Requirements Dimensional requirements pertaining to floor area ratios, dwelling unit densities, and height limitations in the MXD District of the project area shall be as follows: 1) Aggregate GFA: The Aggregate Gross Floor Area ("GFA") of development in the MXD District shall not exceed three million, six hundred and seventy-three thousand, (3,673,000) square feet four million, four hundred seventy three thousand (4,473,000) square feet, plus six hundred thousand (600,000) square feet that shall be limited to multi-family residential, for a total GFA not to exceed four million, two hundred seventy-three thousand (4,273,000) five million, seventy three thousand (5,073,000) square feet. Aggregate GFA of development in the MXD District is at any time the sum of the GFA of all buildings (i) which are then located in the MXD District, (ii) which are being constructed or may be constructed in the MXD District pursuant to the effective building permits, and (iii) which, pursuant to then outstanding contracts (including options) with CRA and so stated in certificates from the CRA to the Superintendent of Buildings, may be constructed in the MXD District in the future.6 [5] [6] [8] [9] [10] [11] 2) Any additional Infill GFA (as that term is defined in Section 504 below) for commercial uses that is not the subject of the existing Concept Plan approved by Special Permit PB #315 on March 20, 2017 (as amended by Amendment #1 (Major) dated January 31, 2019) (collectively, the “Existing Concept Plan”) may only be utilized in conjunction with the development by NSTAR Electric Company d/b/a Eversource (or its successors and assigns) of a substation within the MXD District (“the Substation Project”) and only on property within the MXD District owned by the entity (or an affiliate thereof) that provided the land on which the Substation Project is to be developed. For the purposes of this Plan, the eight hundred thousand (800,000) square feet of Infill GFA for commercial uses that is not the subject of the Existing Concept Plan may sometimes be referred to as “Utility Project GFA”. The issuance of a building permit for the Substation Project shall precede or be issued concurrently with the issuance of a building permit for any project utilizing Utility Project GFA. [11] Additionally, a building permit for construction of a residential project of at least four hundred thousand (400,000) gross square feet shall be issued prior to or concurrently with the issuance of a building permit for any project utilizing Utility Project GFA. The design review process for a residential project of at least four hundred thousand (400,000) gross square feet shall also precede, or proceed concurrently with, the design review process for any project utilizing Utility Project GFA, in accordance with a special permit approving a Concept Plan as set forth in Section 14.32.2 of the Zoning Ordinance. [11] 3) Two hundred thousand (200,000) square feet of the multi-family residential GFA shall occur only within the area designated on the Zoning Map as the “Ames Street District” (the “Ames Street Residential Project”)., the construction of which shall precede the occupancy of any commercial GFA in excess of three million and seventy three thousand (3,073,000) square 6 Previous versions of the Plan included an additional 29,100 GFA provided to Seven Cambridge Center via Amendment 6 and a subsequent variance from the MXD Zoning. The GFA limitations have been revised to match the zoning ordinance and additional language allowing GFA exemptions for variances is added in Section 402 (4).

Kendall Square Urban Redevelopment Plan page 15 1.28.21 feet, other than the 60,000 square feet of commercial space that may be permitted by special permit pursuant to Section 416.1 [10] Additionally, the commencement of construction of a second residential project of at least 200,000 square feet shall precede the occupancy of any commercial GFA utilizing Infill GFA (as defined in Section 504 below) in excess of three hundred and seventy-five thousand (375,000) square feet. [10] 4) Cumulative GFA: In addition to the Aggregate GFA limitation, the Cumulative GFA for each of the use groups shall not exceed the respective amounts stated below, except as provided hereinafter. The sum of the Cumulative GFA limitations below exceeds the Aggregate GFA limitation to provide flexibility between uses in the Project Area. Cumulative GFA for a use group is at any time the sum of the GFA of all portions, occupied or to be occupied by uses within such use group, of all buildings (i) which are then located in the MXD District, (ii) which are being constructed or may be constructed in the MXD District pursuant to then effective building permits, and (iii) which, pursuant to then outstanding contracts (including options) with the CRA to the Superintendent of Buildings, may be constructed in the MXD District in the future. [10] 1. Industrial uses permitted by Section 401(1): Cumulative GFA = 770,000 square feet. 2. Office and Biotechnology Manufacturing Uses permitted by Section 401(2): Cumulative GFA = 2,265,000 3,065,000 square feet. [3] [8] [10] [11] 3. Retail and consumer service uses permitted by Section 401(3): Cumulative GFA = 200,000 square feet. [10] 4. Residential uses permitted by Section 401(4): (i) Multi-family housing: Cumulative GFA = 800,000 square feet. [5] [10] (ii) Hotel/Motel: Cumulative GFA = 440,000 square feet. [4] 5. Entertainment, recreational, institutional, transportation, communication and utility uses permitted by Sections 401(5), 401(6) and 401(7) and additional development of industrial, office, retail, consumer service and hotel/motel uses exceeding the foregoing cumulative GFA limitations: 1 Provision allows the GFA provided by the Whitehead Institute zoning petition to be added independent of the residential obligation.

Kendall Square Urban Redevelopment Plan page 16 1.28.21 Cumulative GFA = 973,000 square feet for buildings which are located or are being constructed or may be constructed at any location within the MXD District. [2] [6] [10] Any construction or change of use within the MXD District, which would cause the foregoing aggregate or cumulative GFA limitations to be exceeded shall not be allowed. The Cambridge Redevelopment Authority (CRA) and Cambridge Inspectional Services Department (ISD – also referred to as the Superintendent of Buildings) shall maintain a record of the Aggregate GFA within the MXD District. The CRA shall also maintain a record of Cumulative GFA for each use group specified in Section 401. The CRA and ISD shall further maintain a separate record of any development within the area of the MXD district designated in Exhibit F as the “Ames Street District.” These records shall be adjusted, as appropriate, from time to time, including upon issuance, revocation, or expiration of a building permit or certificate of occupancy and upon receipt of a certificate from the CRA as to an outstanding contract (including an option) for the construction of a building. Additional building area within the MXD District authorized by variance issued by the Board of Zoning Appeal, shall not be counted by the CRA or the ISD against the GFA Limitations of this Section 402. [9] [10] In determining Cumulative GFA for a building containing uses in more than one use group, spaces to be utilized by users in more than one of the use groups (such as lobbies, interior courts, elevator shafts and basement storage areas) shall be apportioned to each use group in proportion to the share of space that use group will occupy within the building. 5) Floor Area Ratio: In addition to both the Aggregate and Cumulative GFA limitations established herein, there shall also be a density limitation for each within the MXD District. The following Floor Area Ratios (hereinafter referred to as "FAR") for each lot shall not be exceeded, except as provided hereinafter. The area of the lot to be counted in determining FAR shall include land dedicated by the owner or former owner of the lot as public open space under Section 403, as well as developed land. Notwithstanding the provisions of the immediately preceding paragraph, there shall be no maximum FAR for any project utilizing Infill GFA (including Utility Project GFA). However, the other Dimensional Requirements in this Section 402 shall continue to apply. [11] Industrial and Wholesale Uses: FAR 4.0 Office Uses and Biotechnology Manufacturing Uses: FAR 8.0 [3] Retail and Consumer Services Uses: FAR 5.0 Residential uses: - Multi-family housing: FAR 8.0 [10] - Hotel/Motel: FAR 6.0

Kendall Square Urban Redevelopment Plan page 17 1.28.21 Other uses: FAR 4.0 If development on a lot is to include activities in more than one of the uses above, the maximum FAR for the lot shall be the FAR for the use group containing the largest proportion of space on the lot. (4) GFA Exemptions: The following items shall be excluded from the calculation of Aggregate GFA within the District for the purposes of determining compliance with the intensity of development requirements of the Plan and Article 14 of the Zoning Ordinance: (A) Variances: Aggregate GFA within the District authorized by a variance issued by the Board of Zoning Appeal. [9] (B) Residential Outdoor Area Exemptions: Private outdoor decks or balconies, up to five eight percent (58%) of the building floor area for multi-family residential or commercial development. [10] [11] (C) Innovation Space: Innovation Space GFA up to the lesser of either twenty percent (20%) of the Infill GFA dedicated to Office and Biotechnology Manufacturing uses, or one hundred five thousand (105,000) square feet. In order for the Innovation Space to be exempt from the Aggregate GFA limitations, at least twenty five percent (25%) of the Innovation Space utilization (measured by square footage or shared space membership) must be set aside as below market rate space to be offered by the CRA and/or the City to qualifying tenants. [10] [11] (D) Retail: The GFA occupied by retail and consumer service uses listed in Article 14.21.3 of the Zoning Ordinance, if the conditions set forth in Section 14.32.6(4) or 14.72.4, as applicable of the Zoning Ordinance are met. [10] (E) Middle Income Residential Housing Units: The GFA committed to the provision of middle-income housing units per the provisions of Section 411 below. (F) Transfer of Development Rights: Any GFA acquired through the transfer of development rights provisions of the Zoning Ordinance. [10] (G) Electrical Substation: The Substation Project shall be exempt from Aggregate GFA calculation as well as the requirements as to Floor Area Ratio. Further, substation construction shall not constitute Infill GFA (or Utility Project GFA). [11] (H) Educational Lab, Classroom, or Training Facility: Up to twenty thousand (20,000) square feet of educational, health, or workforce training facilities operated to provide services to the general public (as opposed to private facilities that are solely accessible by tenants or occupants of commercial buildings within the MXD District), which such services are either permitted as of right within the MXD District in accordance with the provisions of Article 14 of the Zoning Ordinance or may otherwise be permitted by special permit. [11]

Kendall Square Urban Redevelopment Plan page 18 1.28.21 (5) Building Height Limits The maximum building height for commercial buildings in the MXD District shall be 250 feet, except for the area of the District more than 450 feet north of Broadway where the maximum building height for any portion of a building located in such area shall be 200 feet. Up to two (2) mixed-use buildings elsewhere in the District may be permitted to be built up to 350 feet within the 250-foot building height area of the District provided, however, that the occupied floors above 250 feet may only contain residential uses and associated amenity space. No more than two buildings within the MXD District may exceed 250 feet in height. Additionally the average floorplate of the occupied portions of a building above 250 feet shall not exceed 12,000 square feet. [10] The maximum building height in the MXD District shall be two hundred and fifty (250) feet. Notwithstanding the foregoing, one building within the MXD District may reach four hundred (400) feet provided, however, that the occupied floors above two hundred and fifty (250) feet may only contain residential and associated amenity space. Additionally, the floorplate of any portion of a building above two hundred fifty (250) feet shall not exceed twelve thousand five hundred (12,500) square feet. [11] These requirements shall not apply to chimneys, water towers, air conditioning equipment, elevator bulkheads, skylights, ventilators, solar or wind turbine energy systems, and other necessary features appurtenant to buildings, which are usually carried above roofs and are not used for human occupancy. These requirements shall also not apply to (i) domes, towers or spires above buildings if such features are not used for human occupancy and occupy less than ten percent (10%) of the lot area, (ii) wireless or broadcasting towers and other like un-enclosed structures which occupy less than ten percent of the lot area or (iii) rooftop terraces and enclosed structures ancillary thereto (provided that such structures occupy less than ten percent (10%) of the lot area). [10] Section 403: Open Space Requirements To the maximum feasible degree, the CRA will dispose of project land in such a manner as to achieve the mixture and density of those land uses needed to produce balanced development in accordance with the objectives set forth in Section 102. 1) Public Open Space Requirement: The CRA will reserve at least 100,000 square feet of land in the MXD District for the development of public open space for parks, gardens and plazas. Public open space shall be open space reserved for public use and enjoyment as guaranteed through one or more of the following: [10] (l) Retention by the CRA; (2) Dedication to and acceptance by the City or other public entity; (3) Easements or deed restrictions over such land sufficient to ensure its perpetual reservation for public open space purposes; (4) Dedication, by covenant or comparable legal instrument. to the community use of the residents, lessees and visitors to the MXD District for reasonable amounts of time on a regular basis; or

Kendall Square Urban Redevelopment Plan page 19 1.28.21 (5) Lease agreements of 99 years or longer from the private developer or owner to the City or other public entity. 2) Project Open Space Requirement: Each development project shall be required to contribute to the open space network of the Project Area. Table One lists the minimum amount of open space (public, private or combined) to be provided by each development within the MXD District, subject to the reduction provided hereinafter. When development on a lot includes uses in more than one of the use categories in Table One, the requirement for each use category shall be calculated and totaled to determine a total requirement for the project. This open space requirement may be met by any combination of the following: (a) Creating open space on the development lot. Some or all of this required open space may be designated and also serve as public open space, if reserved by one of the methods specified above. (b) Creating new public open space within the MXD District (not otherwise reserved by another project to meet its lot open space requirement), or enhancing existing open areas to create more publicly accessible open space (e.g., by physical improvements, access dedication, public programming, etc.). The CRA shall set conditions on the level of enhancement necessary to utilize space to qualify as an open space contribution toward the objectives of linking existing open space and activating previously unused open areas. Additionally, a project may provide, as qualifying open space, funding toward sustaining, continuous public programming and maintenance of special features of open space enhancements. [10] (c) Providing land and/or adequate acquisition and development funds for the creation of new public open space, or adequate funds for the enhancement of existing or future public open space, elsewhere within one half mile of the MXD District. This outside of the MXD option may be used to provide up to fifty percent (50%) of the Project Open Space Requirement. The CRA will set a funding level necessary for this financial contribution to meet a portion of the open space requirement, based on the then-prevailing market costs of acquiring, improving and/or enhancing an equivalent amount of space within a comparable open space project. [10] The CRA shall maintain and shall make publicly available a record of Cumulative GFA by land use for the purpose of determining and tracking open space requirements for existing and future development. [10]

For each linear foot of pedestrian way meeting the requirements within Exhibit E provided by a development project, 20 square feet may be deducted from the Project Open Space Requirement. [10]

Kendall Square Urban Redevelopment Plan page 21 1.28.21 Section 404: Vehicular Access, Parking and Loading Regulations 1) Buildings erected in the MXD District need not be located on lots that have frontage on a street. However, provisions for access to all buildings by emergency and service vehicles in lieu of public street access shall be made possible by the layout and design of driveways, interior service roads, or pedestrian and bicycle circulation corridors not normally open to vehicular traffic to the reasonable satisfaction of the City Fire Department, and the City Traffic Department. 2) With the exception of multi-family residential development, there are no minimum parking requirements in the MXD District. Multi-family residential development shall provide a minimum of 0.4 0.25 parking spaces per dwelling unit. All proposed development shall be restricted from constructing parking spaces, either on or off the lot within the MXD District, beyond the maximum allowances of Table Two. The CRA may approve arrangements for shared parking of such residential parking spaces with commercial spaces or otherwise adjust the minimum residential parking requirements based on review and analysis of anticipated parking demand. Otherwise off-street parking allowance for motor vehicles within the MXD District shall be restricted according to building use, with additional standards as follows in Table One: [10] [11] Table Two: Off Street Parking Maximum Allowance Use Group Maximum Parking Allowance Light Industrial and Wholesale Uses .8/1000 sq ft allowed by Section 401(1) Office and Biotechnology Manufacturing Uses .9/1000 sq ft allowed by Section 401(2) Retail and Consumer Service Uses .5 /1000 sq ft allowed by Section 401(4) Residential Uses allowed by Section 401(4) Multifamily housing .75/unit Hotel or Motel 1 / 4 sleeping rooms Other Uses .9/1000 sq ft No permanent surface (i.e. not structured), off-street parking areas shall be allowed in the MXD District.

Section 410: Landscaping All open areas within the project area on land disposed of by the CRA must be suitably landscaped so as to provide a visually attractive environment in accordance with development guidelines established pursuant to Section 502 of the Plan. Section 411: Housing 1) Affordable Housing Requirements Multi-family housing development shall provide that at least a final net twenty percent (20%) of the Infill GFA of new housing development is made permanently available to households qualifying for affordable housing under the Inclusionary Housing Ordinance, or the minimum percentage required by the Zoning Ordinance, whichever is greater. The CRA will utilize this square footage measurement rather than unit counts for meeting this requirement to provide opportunities for larger affordable units with two and three bedrooms to be constructed. [10] 2) Middle Income Housing Middle Income Units (as defined in Article 14.35(c) of the Zoning Ordinance.) shall occupy at least five percent (5%) of the total residential GFA of each residential building utilizing Infill GFA. Such Middle Income Units shall be distributed throughout each residential building and be comparable in size, configuration and quality to the market rate units. The floor area of Middle Income Units provided per this Section 411 shall not be counted against the Aggregate or Cumulative GFA limitations in the District. [10] 3) Dwelling Type Mixture New housing development utilizing Infill GFA shall include a range of dwelling unit types and sizes. At a minimum, five percent (5%) of the residential GFA utilizing Infill GFA shall be devoted to dwelling units with three (3) bedrooms or more, which shall be designed to accommodate families with children. To the extent legally permissible under Section 11.200 of the Zoning Ordinance and other applicable legal requirements, these three-bedroom units will all be Middle Income Units and Affordable Units; provided, however, that if three-bedroom units comprise more than

Kendall Square Urban Redevelopment Plan page 24 1.28.21 five percent (5%) of the total floor area devoted to multi-family residential units, any such units in excess of five percent (5%) of the total floor area may be market-rate units. [10] Section 412: Innovation Space Any proposal for new commercial development utilizing Infill GFA (as defined in Section 14.32.2 of the Zoning Ordinance) and containing more than 100,000 square feet for Office and Biotechnology Manufacturing Uses shall include a plan for Innovation Space meeting the requirements below. Innovation Space within the MXD District must occupy GFA equal to, or in excess of, ten percent (10%) of newly constructed Infill GFA used for Office and Biotechnology Manufacturing Uses. Existing GFA within the MXD District may be converted to meet this requirement. The Innovation Commercial Space requirement shall be met through the provision of office spaces of at least 10,000 square feet within a single building (or ten percent (10%) of newly constructed Infill GFA used for Office and Biotechnology Manufacturing Uses, if less), and may be satisfied by means of a lease to a single user who will operate and manage a facility meeting the requirements hereof. (a) Combined Spaces. Developers of properties within the MXD District may collaborate with other developers in adjacent zoning districts in the Kendall Square area (defined as zoning districts reviewed as part of the K2 Planning Study) to create a Joint Innovation Space Plan. In such a case, the total square footage of joint Innovation Space must be large enough to satisfy the sum of the requirements, if any, for such participating developers and zoning districts. (b) Characteristics. For the purposes of this Section 412, Innovation Space shall have the characteristics specified in Article 14.32.5(c) of the Zoning Ordinance. (c) Variations. In reviewing development proposals, variations in the specific characteristics set forth above, may be allowed if the proposed Innovation Space is found to be consistent with the purposes of these characteristics. [10] (d) Inapplicability to Utility Project GFA. Notwithstanding the foregoing provisions of this Section 412, there shall be no innovation space requirement for any project utilizing Utility Project GFA (nor shall any such project utilizing Utility Project GFA be entitled to utilize Innovation Space in order to obtain a GFA Exemption under Section 402(4) above). [11] Section 413: Interim Uses The CRA may devote real property designated to be acquired, or acquired under special conditions, prior to the time such properties are needed for disposition for reuse and development in accordance with the provisions of the Urban Renewal Redevelopment Plan to temporary, interim uses for signs for project identification, relocation, parking, traffic circulation and public transportation, project or site improvements or building construction, storage, recreation, or landscaping in accordance with such provisions, requirements, standards, controls, and regulations as the CRA may deem essential, necessary, or appropriate to the carrying out of the objectives of the Urban Renewal Redevelopment Plan.

Kendall Square Urban Redevelopment Plan page 27 1.28.21 CHAPTER 5: DESIGN PRINCIPLES, DEVELOPMENT GUIDELINES AND DESIGN REVIEW, AND REDEVELOPMENT PROPOSALS ________________________________________________________________ Section 501: General Design Principles Proposals by redevelopers shall be designed to: (1) Create an environment which will be lively and attractive and provide daily amenities and services for the use and enjoyment of the working population and City residents. (2) Establish an active urban character for the area by the intensive utilization of land and by the mixing of compatible land uses, especially near the Kendall rapid transit station. (3) Achieve a proper integration of buildings and spaces within and outside the project area by carefully relating the scale and materials in new development both among project components and with respect to the scale and materials of surrounding development. (4) Establish a focus through building form and open space which will serve to create development identity of sufficient positive impact. (5) Preserve and enhance long and short-range views, visual privacy, and sun orientation by the careful positioning of buildings and open space. (6) Obtain a relationship between buildings, open space and public ways, which provides increased protection to the pedestrian during unfavorable weather conditions. (7) Link all project components with continuous and safe pedestrian and bicycle circulation systems. [10] (8) Establish an orderly sequence and hierarchy of open spaces and pedestrian routes throughout the site. (9) Provide maximum opportunity for safe and convenient pedestrian and bicycle access to surrounding areas. [10] Section 502: Development Guidelines The CRA shall from time to time establish land disposition policies and procedures, design standards, and other development guidelines and evaluate the quality and appropriateness of development proposals with reference to the Plan objectives, land use provisions, building requirements, design principles and other controls as set forth in this Plan, in the disposition documents, and development guidelines.

Kendall Square Urban Redevelopment Plan page 38 1.28.21 Exhibit D: Historic Relocation Assistance Program A relocation assistance program was established by the CRA for this purpose of finding standard dwelling or business accommodations to meet the rehousing and business relocation needs of displaced residents and business, within their financial means, in reasonably convenient locations at the earliest practicable time. The basic objectives of the relocation assistance program were: 1) To provide such measures, facilities, and services as were necessary to determine the needs of displaced site occupants for relocation assistance; and 2) To make information and assistance available to them in such a way as to minimize the hardships of displacement. Assistance included the making of such relocation payments as were provided for under the provisions of Federal, State, or local laws and regulations. The CRA administered the relocation assistance program. It was the only agency responsible for the relocation of site occupants displaced from the Project Area as a result of its land acquisition. There were some 10 families and individuals who occupied property, all of whom were relocated when the Project Area was originally cleared. [10] The method for the relocation of persons previously living in the Project Area, and the availability of and the means by which there were provided dwelling units for such persons substantially equal in number to the number of dwelling units cleared from the Project Area were as follows: 1) Method for Relocation: Each dwelling unit vacancy found by or referred to the CRA will be inspected for the CRA by a trained housing inspector in order to determine (l) that it is decent, safe, and sanitary; (2) that it complies with the provisions of the Cambridge Housing Code; (3) that it contains adequate heating, lighting, cooking, and sanitary facilities; and (4) that it is structurally sound. Only standard dwelling units reasonably accessible to the places of employment of displaced site occupants, and in areas not less desirable in regard to public utilities and commercial facilities than the project area, will be referred to families and individuals to be displaced from the Project Area. The cost of any dwelling unit referred to a family or individual for rehousing purposes will, generally, not exceed (l) one-quarter of monthly income, in the case of dwelling units for rent, or (2) twice annual income, in the case of dwelling units for sale. In order to make such referrals, the CRA will secure and maintain listings of all standard dwelling units for sale or rent in Cambridge and the Cambridge housing market area. Preference will be accorded by the Cambridge Housing Authority to persons who appear to be eligible for (l) state-aided veterans’ housing and housing for the elderly; and (2) federally-aided low-rent housing and housing for the elderly. Persons eligible to be

Kendall Square Urban Redevelopment Plan page 39 1.28.21 accorded preference will be admitted to public housing projects under “continued occupancy” income limits by the Cambridge Housing Authority. (b) Availability of Dwelling Units: Availability of private rental housing: As of the date of the original adoption of the Plan, records maintained by the CRA indicated that 1131, 1083, 1105 and 1126 private dwelling units were available for rent in the City alone for each year during a recent four- year period. [10] Availability of private sales housing: As of the date of the original adoption of the Plan, records maintained by the CRA indicated that 107, and 122 private dwelling units were available for sale in the City alone for each year during a recent two-year period. [10] Availability of public housing: As of the date of the original adoption of the Plan, records maintained by the Cambridge Housing Authority, as reported in December of 1964, indicated that 220 dwelling units in public housing developments become available on the average for occupancy each year. Clearly, dwelling units for the relocation of persons living in the Project Area at that time substantially equal in number to the number of units to be cleared are available, as are the means by which they can be provided through suitable methods, for the relocation of persons now living in the project area. [10]
