MARKUP VERSION -– Additions and creations underlined, deletions in strikethrough Multifamily Housing Zoning Petition – Part One City of Cambridge, MA Page 4 of 70 3.32.1Where more than one-half the area of said lot is in a less restricted district, (either in terms of the district's overall regulations or a single regulation), the Board of Zoning Appeal may grant a special permit allowing any of the less restrictive dimensional regulation(s) to may be extended up to twenty-five (25) feet into the more restricted district as-of-right for buildings or portions of buildings containing residential uses listed in Section 4.31 a-j or upon issuance of a special permit by the Board of Zoning Appeal for buildings or portions of buildings containing other uses. Uses not allowed in the more restricted districts shall not extend into the more restricted districts. 3.32.2Dwelling units and/or gGross floor area allowed in the more restricted district, according to the formulas specified in Subsection 5.27, may be located in the less restricted district, but dwelling units or gross floor area allowed in the less restricted districted may be located in that portion of the lot located in the more restricted district only to the extent permitted in Section 3.32.1. Amendments to Article 4.000. Amend Section 4.21, Paragraph c. to read as follows: c. Provisions of garage or parking space for occupants, employees, customers, or visitors shall be considered as an accessory use, provided that where accessory to residential uses in Residence A and B districts such garage or parking space shall be limited to the accommodation of three passenger vehicles, or two passenger vehicles for each dwelling unit, whichever is greater. Amend Section 4.21, Paragraph h. to read as follows: h. In Residence A, B, C, and C-1 Districts an accessory building shall not be located nearer than ten (10) feet to the principal building or nearer than five (5) feet to any side or rear lot line or nearer to the frontany lot line than the minimum setback in the zoning district. Amend Section 4.21, Paragraph j. to read as follows: j. A dwelling or mobile home shall not be considered an No accessory building shall be used as a dwelling except in an Industrial District for the accommodation of a night watchman or janitor or if it otherwise meets the definition of an Accessory Apartment. Amend Section 4.21, Paragraph k. to read as follows: k. An accessory building in Residence A, B, C, C-1, and Office-1 districts shall not exceed fifteen (15) feet in height above the ground level. Amend Section 4.22 to read as follows: 4.22Accessory ApartmentsAccessory Apartments shall be permitted in all zoning districts where Residences are permitted. The purpose of this Subsection 4.22 is to allow for the creation of accessory apartments in all districts. Many large existing single and two-family dwellings or other accessory buildings on their lots are underutilized. Alteration of these buildings to provide one additional dwelling unit on the lot would be prohibited in most cases due to the existing floor area ratio and/or lot area per dwelling unit requirements of Subsection 5.31, among other zoning limitations. Given contemporary lifestyles,

MARKUP VERSION -– Additions and creations underlined, deletions in strikethrough Multifamily Housing Zoning Petition – Part One City of Cambridge, MA Page 5 of 70 housing needs, and energy and maintenance costs, it is beneficial to the City to allow greater flexibility in the use of such buildings to add new dwelling units without substantially altering the environmental quality of their surrounding neighborhoods. This Subsection 4.22 gives the Board of Zoning Appeal the authority to relax such requirements in certain instances as enumerated below. 4.22.1In all districts the Board of Zoning Appeal may grant a special permit for the alteration of an existing single-family detached dwelling, two-family dwelling, or accessory building on the same lot as a single-family or two-family dwelling to provide one accessory apartment if the following conditions are met: 1. The building containing the accessory apartment has been in existence since on or before February 1, 2019. 2. In the case of an accessory apartment within a single-family or two-family dwelling, prior to alteration the dwelling contains at least one thousand eight hundred (1800) square feet of gross floor area. 3. In the case of an accessory apartment within a single-family or two-family dwelling, such accessory apartment shall not occupy more than 900 square feet or thirty-five (35) percent of the gross floor area of the principal dwelling, whichever is less. An accessory apartment created within an accessory building shall not occupy more than 900 square feet. 4. No more than one accessory apartment shall be allowed on any lot. 4.22.2In all districts any existing two-family dwelling may be converted to a single-family detached dwelling with one accessory apartment by right, without need for a Special Permit, if the conditions set forth in Section 4.22.1 above are met. 4.22.3In granting a special permit for an accessory apartment, the Board may relax or waive applicable zoning requirements to enable the creation of the accessory apartment as set forth below: 1. Accessory apartments shall not be counted in applying the lot area per dwelling unit limitations of the zoning district. 2. The Board may relax applicable floor area ratio (FAR) or gross floor area (GFA) limitations, to the extent necessary, to enable the creation of an accessory apartment within the envelope of an existing structure; however, any additional GFA created outside the envelope of the existing structure shall comply with applicable FAR or GFA limitations for the lot. 3. The Board may alter applicable yard setback or height limitations, to the extent necessary, to enable site improvements that may be required to ensure the safe habitation of the accessory apartment, including but not limited to emergency egress routes; however, any movement or alteration to the principal exterior walls or roof of a building shall comply with applicable yard setback and height limitations for the lot. 4. No off-street parking shall be required for an accessory apartment. 4.22.4In granting a special permit for an accessory apartment, the Board shall determine that the General Special Permit Criteria set forth in Section 10.43 of this Zoning Ordinance are met and that any alterations that are visible from the exterior of the building shall be compatible with the appearance and character of the neighborhood and are minimally necessary to enable the creation of the accessory apartment. The Board may impose such conditions as it may deem appropriate to ensure ongoing compliance with such criteria and to avoid undue detriment to the neighborhood or to nearby persons or property.

In Residence B, C, C-1, C-1A, 2, 2A, 2B, 3, 3A, and 3B Districts, certain Retail and Consumer Service Establishments identified in the Table of Use Regulations may be allowed by special permit from the Board of Zoning Appeal, subject to the criteria set forth in Sections 10.43 and 10.43.1 of this Zoning Ordinance, if all of the following conditions are met: Amend Section 4.53 to read as follows: 4.53Approach. This Section 4.50 establishes special use regulations for institutional activities in the Residence A-1, A-2, B, C and C-1 zoning districts. These regulations encompass the full range of institutional uses. Each use is regulated based on its expected physical impacts on nearby residences, on the existing or recent use of the lot or structure proposed for such use, and on the location of the lot either within or outside of an area in which there has already been extensive institutional development. Amend Section 4.54 to read as follows:

MARKUP VERSION -– Additions and creations underlined, deletions in strikethrough Multifamily Housing Zoning Petition – Part One City of Cambridge, MA Page 9 of 70 4.54Institutional Overlay District. The designation Institutional Overlay District is hereby established on the Zoning Map as provided for in Subsection 3.12. An Institutional Overlay District delimits an area where there has been extensive contiguous development of institutional use types subject to regulation under this Section 4.50. Institutional Overlay Districts are defined in order to identify areas where prior development patterns create a precedent for more flexible institutional use regulation than in areas where non institutional uses predominate. The conditions regarding development of new or expanded institutional uses under Subsections 4.55 and 4.56 are determined in part by whether a lot is located inside or outside an Institutional Overlay District. The boundaries of these districts are drawn based on several physical factors; consequently, for purposes of definitional clarity, they encompass areas both inside and outside zoning districts subject to use regulation under this Section 4.50. Regardless of the location of an Institutional Overlay District boundary, the special institutional use regulations of this Section 4.50 shall only apply within the Residence A-1, A-2, B, C and C-1 districts. The following Institutional Overlay Districts are hereby established on the Zoning Map. Amend Section 4.55 to read as follows: 4.55Existing Lot Status. The institutional use of land or structures for each category of institutional activity in a Residence A-1, A-2, B, C and C-1 district shall be governed by the Table of Institutional Use Regulations in Subsection 4.56. The institutional use regulation in the table shall be the same in the aforementioned five (5) zoning districts, but shall differ according to: (1) the applicable use category, (2) the location of the lot in relation to the Institutional Overlay Districts, and (3) the status of the lot in relation to its existing or recent use. If two or more of the lot status types listed below would pertain to the proposed development of an institutional use, then the more restrictive designation among the types of lot status for the use would apply. The column heading in Subsection 4.56 refers to the types of lot status listed in Subsection 4.55.1 and applies to institutional development whether by conversion of an existing structure or lot or by new construction or new use of a lot. Amendments to Article 5.000. Amend Section 5.11 to read as follows: 5.11No building or structure shall be built nor shall any existing building or structure be enlarged which does not conform to the regulations as to maximum ratio of floor area and lot areas, minimum lot sizes, minimum lot area for each dwelling unit or equivalent, minimum lot width, minimum dimensions of front, side, and rear yards and maximum height of structures, in the several districts as set forth in Article 5.000, Section 5.30 except as hereinafter provided and except in the Cambridge Center MXD District, which shall be governed by the requirements of Section 14.30. Amend Section 5.13 to read as follows: 5.13In the case of multiple buildings on a lot that do not contain Residences as listed in Section 4.31 a-j., the minimum distance between such buildings shall not be less than the sum of the heights of the buildings divided by six or ten feet, whichever is greater. In determining compliance with this section, portions of buildings exempted by Section 5.23 shall not be counted in computing building height. Delete Section 5.14 as follows: 5.14[Deleted]For residential uses permitted in Residence A, B, C, and Office districts which are not divided into dwelling units, each one thousand square feet of gross floor area of the building shall be considered equivalent to one dwelling unit for purposes of computing minimum lot area.

This paragraph shall not apply where a portion of the lot or development parcel is acquired for a public purpose. This paragraph shall not apply to townhouse development, as governed by Section 11.10. Amend Section 5.21.1 to read as follows: 5.21.1There shall be no required minimum lot area or width except as set forth belowOn lots of less than the required area for the district in which they are located and which have been duly recorded by plan or deed with the Registry of Deeds before the date of the first passage of the applicable provisions of this or any prior Ordinance the minimum lot size and lot width regulations need not apply, but the floor area ratio and the minimum lot area regulations for each dwelling unit shall be applicable. In case of such lots of less than the required width the sum of the two required side yards need not be more than thirty (30) percent of the lot width, except that each side yard shall be a minimum of seven feet, six inches (7' 6").

This Section explains how the height limits in the Table of District Dimensional Regulations in Section 5.30 apply. (a) Buildings or portions of buildings used as Residences, listed in Section 4.31 a-j of this Zoning Ordinance, are generally limited by the maximum number of Stories Above Grade and by the maximum building height above grade in feet, which is intended to enable the allowed number of Stories Above Grade while limiting excessive story height. Where there is no explicit limit on Stories Above Grade, including but not limited to special districts, overlay districts, or PUD districts, any number of Stories Above Grade shall be permitted within the applicable height limit.

Where the computation of the total number of dwelling units allowed in each district results in two fractional numbers and where the sum of the resulting remainders from both districts equals or exceeds one, an additional unit shall be permitted. 5.27.2To the extent that FAR or GFA limitations are applicable to a particular use, Tthe maximum gross floor area permitted for that use on a lot located in two or more zoning districts shall be the sum of the total allowed gross floor area permitted for that use in each districtportion of the lot, typically determined by adding multiplying the lot area in each district multiplied by the maximum allowed floor area ratio (FAR) for that use in that for each district and adding the results for each portion of the lot. Maximum Gross Floor Area = (Lot area in district 1 x district 1 FAR applicable to that use) + (Lot area in district 2 x district 2 FAR applicable to that use) Delete Section 5.28.1 as follows: 5.28.1[Deleted]Dwellings in Non Residential Districts. A dwelling shall be subject to the dimensional standards generally applicable in the district set forth in the Tables of Dimensional Requirements in Section 5.30, except as provided for below. a. A dwelling in a Business A district shall be subject to the same dimensional requirements and other restrictions as a dwelling in a Residence C-2B district, except that the height limitation on lots abutting Hampshire Street shall be sixty-five (65) feet. b. A dwelling in a Business A-1 district shall be subject to the same dimensional requirements and other restrictions as a dwelling in a Residence C-1 district. c. A dwelling in a Business B district shall be subject to the same dimensional requirements and other restrictions as a dwelling in a Residence C-3 district. Amend Section 5.28.2 as follows (with the intent of facilitating as-of-right conversions to residential use if they conform to existing conditions or underlying zoning standards): 5.28.2Conversion of Non Residential Structures to Residential Use. Where it is proposed to convert an existing principal use structure, designed and built for non residential use, to residential use (excluding Transient Accommodations listed in Section 4.31.1 and Trailer Park or Mobile Home Park listed in Section 4.31 (j)), the dimensional standards generally applicable in the district as set forth in the Tables of Dimensional Requirements in Section 5.30 and other applicable regulations in this Ordinance, including permitted uses, Section 4.30 - Table of Use Regulations, shall apply except where modifications are permitted, either as-of-right or . However, where some or all of those requirements cannot be met, including any use, dimensional or procedural requirement that may apply in the base district, the

MARKUP VERSION -– Additions and creations underlined, deletions in strikethrough Multifamily Housing Zoning Petition – Part One City of Cambridge, MA Page 13 of 70 following provisions shall apply to such conversion after issuance of a special permit by the Planning Board, as set forth below. The provisions in this Section 5.28.2 shall apply in all zoning districts with the exception of districts with an Open Space designation. Intent of this Section: (a) To allow the economic reuse of buildings that may be substantially out of compliance with the dimensional requirements of the zoning district within which they are located, especially as they are converted to residential use. (b) To encourage the preservation of buildings of historic or cultural significance by providing opportunities for reuse of the structures. (c) To establish a framework of development standards and criteria within which existing non-residential buildings that are out of scale and character with surrounding residential uses can be converted to housing of an appropriate style and density while limiting potential negative impacts on neighbors. 5.28.20Allowed Uses. The Planning Board may by special permit authorize uses not otherwise allowed in the base zoning district, subject to the following conditions and limitations: (a) The permitted uses shall be limited to the following: (1) All residential uses listed in Section 4.31 (a-h), but specifically excluding Transient Accommodations listed in Section 4.31.1 and Trailer Park or Mobile Home Park listed in Section 4.31 (j). (2) The following institutional uses: Religious uses (4.33.a); Public or non-profit educational uses (4.33.b.1); Private preschool, day care, kindergarten (4.33.b2); Local government or other government facility (4.33.f, 4.33.g); Private museum, library, non-commercial gallery (4.33.h.2). (3) The following office uses: Office of an accountant, attorney, or other non-medical professional (4.34.b); Real estate, insurance or other agency office (4.34.c); General office use (4.34.d). (4) Any uses allowed as accessory uses to the permitted principal uses. (b) All permitted non-residential uses shall be limited to the ground floor or basement of the building. The Planning Board may permit non-residential uses to occupy other floors of the building only after determining that the location and design of such spaces, including access and egress, will not impact the privacy or security of residential occupants. However, the total floor area occupied by non-residential uses shall not exceed the floor area of the ground floor and basement. (c) The Planning Board shall determine that any proposed non-residential uses are generally compatible with residential uses in the area, including the dwelling units located within the same building, and will not cause harm or nuisance to surrounding uses. (d) The Planning Board shall determine that by permitting non-residential uses, there will be a compensating reduction in the number of dwelling units that would otherwise be permitted, and that the proposed non-residential uses will balance the potential adverse impacts of additional residential units, such as demand for nighttime parking.

Permitted residential uses shall not be limited by GFA or FAR. Permitted non-residential uses shall be subject to the FAR or GFA limitations applicable to non-residential uses in the zoning district.The Gross Floor Area permitted shall be that which is the result of the application of the FAR permitted in the district in which the structure is located, or the existing Gross Floor Area of the structure itself, whichever is greater. However, the Planning Board may permit additional Gross Floor Area to be added to the non residential structure without limit provided all construction creating additional Gross Floor Area occurs within the physical limits of the existing structure. Where it is proposed to add Gross Floor Area above what would normally be allowed in the zoning district, the Planning Board shall determine that such additional floor area is necessary to accommodate a reasonable arrangement and layout of residential units within the existing structure. If Gross Floor Area is added to an existing structure such that the resulting Gross Floor Area is greater than twice what would be allowed under normal zoning district regulations (including the Inclusionary Housing provisions of Section 11.200 if applicable), then half the amount of Gross Floor Area added to the existing structure such that it exceeds twice the normal district limit shall be deducted from the total Gross Floor Area of the structure for the purpose of calculating the maximum permissible number of dwelling units under Subsection 5.28.22 below. For projects of at least 30,000 square feet or twenty (20) dwelling units for which the total Gross Floor Area is greater than twice what would be allowed under normal zoning district regulations (including the Inclusionary Housing provisions of Section 11.200 if applicable), no more than seventy percent (70%) of the project's total Gross Floor Area shall be occupied by living space within private dwelling units, and the remaining Gross Floor Area shall be occupied by common areas such as hallways, stairways, lobbies, fitness/recreational spaces, common storage areas, above-grade parking facilities, laundry or other resident services, or approved non-residential uses. 5.28.22Dwelling Units. There shall be no limit on the number of dwelling units permitted shall be the number of dwelling units allowed under normal zoning district regulations (including the Inclusionary Housing provisions of Section 11.200 if applicable). However, the Planning Board may permit a greater number of dwelling units, with the maximum permissible number of units determined by dividing the Gross Floor Area of the structure as permitted in Section 5.28.21 above, after subtracting any Gross Floor Area occupied exclusively by non-residential uses as permitted under Section 5.28.20, by 1,100 square feet for the first ten (10) units and by 1,900 square feet for any additional units. If a portion of the dwelling units meet the definition of Elderly Oriented Housing (notwithstanding the number of such units within the building), the Planning Board may permit the number of units to exceed the allowed maximum only for the specific purpose of accommodating such units, which may be smaller than conventional housing units. 5.28.23Yard Requirements. The required yards shall be those of the structure existing at the time of the conversion to residential use. However, any construction occurring outside the limits of the existing structure shall be subject to the yard requirements of the district in which the structure is located. 5.28.24Maximum Stories Above Grade and Building Height.

MARKUP VERSION -– Additions and creations underlined, deletions in strikethrough Multifamily Housing Zoning Petition – Part One City of Cambridge, MA Page 15 of 70 (a) The maximum Stories Above Grade and maximum building height, respectively, shall be that heightthose permitted for residential uses in the district in which the structure is located, or the building heightthe pre-existing conditions of the non-residential building, whichever is are greater. However, a (b) Any construction that occurs outside the existing limits of the structure, other than construction exempt from the height limit as set forth in Section 5.23, shall be subject to the applicable maximum Stories Above Grade and building height limit of the district in which the structure is located. (c) In granting a special permit, the Planning Board may approve the construction of additional Stories Above Grade beyond those permitted in Paragraph (a) if they are contained entirely within the existing structure and the Planning Board finds that the additional Stories provide space suitable for dwellings, in addition to meeting other applicable special permit criteria. 5.28.25Private Open Space Requirements. The Private open space requirement shall be that required in the district in which the structure is located, except as modified herein. The dimensional and locational limitations for Private open space set forth in Section 5.22 shall not apply; any combination of at-grade private open space and decks and balconies at other levels shall be permitted as shall walks intended for non vehicular use. However, in every case where those requirements of Section 5.22 waived by this Paragraph (a) are not met, all portions of the surface of the lot shall be Green Area as defined in Article 2.000 that are (1) not covered by the building or (2) devoted to the minimum area necessary to provide at grade, conforming parking spaces and the minimum necessary circulation and driveways for no more than one parking space per dwelling unit. The amount of Private open space required may be reduced upon issuance of a special permit by the Planning Board should the Board find that full compliance cannot reasonably be expected given the existing development of the lot and the provision of parking necessary to serve the dwelling units. However, where open space requirements are not met, the Applicant shall explore the use of portions of the interior of the building to provide recreational opportunities not possible on the exterior. 5.28.26Conforming Additions. Conforming additions to such non-residential structures shall be permitted without reference to the limitations set forth in Section 8.22 for such additions to non-conforming structures. 5.28.27Required Parking. Off-street parking shall be provided as required in the Schedule of Parking and Loading Requirements, Section 6.36. In instances where 6.36 does not apply due to the proposed use not being allowed in the base zoning district, required off-street parking for approved residential uses shall be provided at a rate of one space per dwelling unit, and required off-street parking for non-residential uses shall be determined by the Planning Board after reviewing the requirements for that use within other zoning districts. 5.28.28Criteria for Approval of a Special Permit. In acting upon thisgranting any special permit, the Planning Board shall consider the standards and criteria set forth in Sections 10.43 , 10.47 and 10.47.1and the Urban Design Objectives set forth in Section 19.30 of this Ordinance in addition to the following review standards. 5.28.28.1Criteria Applicable to All Projects.

MARKUP VERSION -– Additions and creations underlined, deletions in strikethrough Multifamily Housing Zoning Petition – Part One City of Cambridge, MA Page 16 of 70 (a) Provision of Parking. Where it is proposed to add dwelling units above the limits established in the base zoning regulations, the Board shall evaluate the impact of increased numbers of dwelling units above that normally permitted in the district on the demand for on-street parking by residents and visitors to the proposed building, particularly in neighborhoods where off street parking is limited. In reaching a determination, the Board may require that the Applicant provide elements of a Parking Analysis as set forth in Section 6.35.3 of the Zoning Ordinance. Where a project is subject to additional criteria as specified in Section 5.28.28.2 below, a Parking Analysis shall be required to be included with the Special Permit Application. (ba) Privacy Considerations. Where significant variations from the normally required dimensional standards for the district are proposed, the Board shall evaluate the impact on residential neighbors of the new housing use and any other proposed use as it may affect privacy. The location and size of windows, screening elements, decks, entries, security and other lighting, and other aspects of the design, including the distribution of functions within the building, shall be reviewed in order to assure the maintenance of reasonable levels of privacy for abutters. In reviewing a proposed development plan, the Board shall consider, among other factors, the potential negative impacts of the new activity on abutters as a result of the location, orientation, and use of the structure(s) and its yards as proposed. (cb) Reduction in Private Open Space. Where it is proposed to reduce the amount of on-site Private Open Space below that required in the applicable district, the Board shall evaluate the proposal in light of the following: (1) The extent to which screening and buffering from neighbors will be accomplished (2) The quality and viability of the proposed open spaces as they are designed (3) The tradeoff in benefits and negative impacts of the loss of green space in order to provide the required amount of parking, including consideration of the feasibility of alternate parking arrangements that might produce additional green area, such as placing some or all parking within the structure (4) The availability of common recreational spaces within the building to compensate for the loss of usable outdoor open space (dc) Community Outreach. The Planning Board shall consider what reasonable efforts have been made to address concerns raised by abutters and neighbors to the project site. An applicant seeking a special permit under this Section 5.28.2 shall solicit input from affected neighbors before submitting a special permit application. The application shall include a report on all outreach conducted and meetings held, shall describe the issues raised by community members, and shall describe how the proposal responds to those issues. 5.28.28.2Additional Criteria Applicable to Larger Projects. Where the proposed project includes more than 10,000 Gross Square Feet or more than ten (10) dwelling units, and the proposed Gross Floor Area or number of dwelling units isStories Above Grade are increased above the maximum allowed under base zoning regulations, the Board shall evaluate the proposal in light of the following: (a) The implications of the size or number of additional dwelling units on the anticipated demand for parking. In order to assist the Planning Board in evaluating parking impacts, an applicant for a special permit shall be required to submit a Parking Analysis, as set forth in Section 6.35.3 of the Zoning Ordinance, as part of the special permit application.

MARKUP VERSION -– Additions and creations underlined, deletions in strikethrough Multifamily Housing Zoning Petition – Part One City of Cambridge, MA Page 17 of 70 (b) The appropriateness of the proposed layout of floor space within the building for a multifamily residential use, with attention to the typical range of unit sizes and types that would be expected for housing in the neighborhood. Considerations may include the suitability of proposed unit configurations for a variety of households, the extent to which unusual unit sizes or shapes may impact parking or overall quality of life for residents or neighbors, and the availability of customary amenities for residents such as storage, utilities, common rooms and recreational facilities. (c) The potential mitigating effects of the proposed occupancy of dwelling units. For instance, units designed for elderly residents or live/work spaces for professionals or artists may provide desirable housing options for Cambridge residents with fewer adverse impacts on parking or neighborhood character. Delete Sections 5.30.1, 5.30.11, and 5.30.12. 5.30.1Rules for Applying Certain Provisions of the Tables of Dimensional Requirements 5.30.11FAR and Height. Where two numbers appear in Column (1) - Maximum Ratio of Floor Area to Lot Area and Column (6) Maximum Height in Feet, the first number shall apply to all permitted uses in the district except Residential Uses, Section 4.31 a-h, and Dormitory (but excluding resident fraternity or sorority) Uses, Section 4.33 b(7), both of which shall be governed by the second number. 5.30.12Calculation of Permitted Gross Floor Area on a Lot Where two numbers regulate the permitted FAR on a lot, the Gross Floor Area of any uses proposed on the lot shall be determined by the following formula: Gross Floor Area Permitted = [(A × FAR 1 ) × Lot Area] + [(B × FAR 2 ) × Lot Area] Where A equals the percentage of Gross Floor Area in the building to be used for nonresidential use(s), and Where B equals the percentage of Gross Floor Area in the building to be used for residential and dormitory use(s), and Where A + B = 100% (or 1.0) or less, and FAR 1 equals permitted FAR for nonresidential uses, and FAR 2 equals permitted FAR for residential and dormitory uses. Replace in their entirety Sections 5.30 and 5.40 to read as follows. Note that this amendment will consolidate tables and footnotes that are separated by district type in the current zoning into a single Table of District Dimensional Requirements and set of footnotes. Where markups are shown below, they only indicate substantive changes to development standards and do not necessarily include all formatting changes: 5.30 DISTRICT DIMENSIONAL REGULATIONS 5.30.1 Dimensional regulations shall apply as set forth in the table below for the indicated zoning districts.

For those portions of any lot exceeding five thousand (5,000) square feet, the applicable Maximum Ratio of Floor Area to Lot Area shall be 0.35 for all permitted residential uses and the Minimum Lot Area for Each Dwelling Unit shall be four thousand (4,000) square feet. However, for any lot in existence as of June 30, 1995 that is subsequently subdivided into two or more lots, the total amount of gross area and number of units on the subdivided lots, in total, shall at no time exceed that permitted by this footnote (j) on the lot before the subdivision occurred. Unless otherwise permitted by special permit from the Board of Zoning Appeal, the gross floor area and dwelling units permitted on each subdivided lot shall be in the same ratio as that lot's area is to the area of the unsubdivided lot. Nothing in this footnote (j) shall prohibit the subdivision of a Townhouse Development conforming at the time of its construction, as permitted in Section 11.10. (k9) Yard Requirements for non-residential buildings in the Residence C-2B District 1(a) Setbacks—In the Residence C-2B District, non-residential buildings shall comply with these yard requirements by being set back above and below ground. 2(b) Green Area—general. Two of the yards on a lot shall consist exclusively of green area as defined in section 2.000. Contrary to the provisions of said definition, hard surfaced walks and terraces shall not exceed twenty-five (25) percent of the area of each yard. At a minimum, green area setback shall consist of permanently maintained densely planted trees and shrubs that may be expected to form within three (3) years after the time of planting a continuous unbroken, year round visual screen. Every effort shall be made to retain the best existing trees in said setbacks to meet the requirements this section in whole or in part. Plans for landscaping and maintenance shall

No Certificate of Occupancy may be granted until landscaping under the terms of this section is completed. (3c) Lots with more than four yards. If the shape of a lot creates a situation where there are more than four yards, this green area requirement shall apply to half of the yards, rounded up in the instance of an odd number of yards. (4d) Lots in two or more zoning districts. Where a zoning district boundary line or lines split a lot, a lot partially in the Residence C-2B district shall comply with provisions elsewhere in this zoning ordinance with regard to lots in two or more zoning districts, except that the setback and green area requirements of this footnote shall apply to all parts of the lot regardless of zoning district. (5e) Lots abutting more restrictively zoned districts. When any lot abuts a more restrictively zoned district or districts, all yards abutting the more restrictively zoned district)s) shall be designated as yards required to comply with the green area requirements of this footnote. This provision shall apply to that quantity of abutting yards numbering up to and including the maximum number of green area yards required by this footnote. The total number of green area yards required on a lot shall not be changed by the provisions of this subsection (5). (6f) Pedestrian and vehicular access. (ai) When a yard used to satisfy the Green Area Open Space requirement of this footnote is a front yard, the Green Area Open Space may be interrupted by not more than one path for pedestrian access to the building. Said pedestrian path shall be constructed perpendicular to the lot line and shall not be more than eight (8) feet wide. The green area yard may also be interrupted by not more than one driveway constructed perpendicular to the lot line and which is not more than twelve (12) feet wide. (bii) The sum of the width of the said pedestrian path and driveway may not exceed the setback provided by the smallest of the yards provided on the lot. (ciii) The areas allowed to be used for access under this subsection (6) shall be counted as part of the twenty-five (25) percent of the total required green area which is allowed to be use for hard surfaced walks and terraces for the front yard in which the access areas are constructed. (7g) Townhouse Development When a lot is used for townhouse development, the provisions of this footnote shall apply to the lot before subdivision into townhouse lots. Subdivision into townhouse lots shall be done in such a manner as to not affect the application of this footnote to the entire unsubdivided lot. In particular, the pedestrian path and driveways allowed. (l10) These requirements may be reduced to a minimum required setback of ten (10) feet with the grant of a special permit from the Planning Board provided that the yard is suitably landscaped to effectively buffer the building walls from abutting lots. (m11) For purposes of calculating FAR and for no other purpose, notwithstanding the definition of Lot in Article 2.000, a Lot in the Residence C-3B district may contain non-contiguous parcels provided that all parcels are held in identical ownership, are all located within the Residence C-3B district orf any abutting Business B district, and further provided that development on any contiguous portion of the lot does not exceed an FAR of 4.0.

Setback exceptions: (a) In a Residence A-1 or A-2 district a dwelling need not set back more than the average of the setbacks of the buildings, other than accessory buildings, on the lots adjacent thereto on either side, but in no case may any part of a building or accessory building extend nearer to any street line, or building line if such has been established, than fifteen (15) feet. A vacant lot or lot occupied by a building set back more than twenty-five (25) feet in a Residence A-1 district and more than twenty (20) feet in a Residence A-2 district shall be considered as though occupied by a building set back twenty-five (25) feet and twenty (20) feet respectively. (b) In a Residence B district a dwelling need not set back more than the average of the setbacks of the buildings, other than accessory buildings, on the lots adjacent thereto the on either side, but in no case may any part of a building or accessory building extend nearer to any street line, or building line if such has been established, than ten (10) feet. A vacant lot or a lot occupied by a building set back more than fifteen (15) feet shall be considered as though occupied by a building set back fifteen (15) feet. (c13) In a Residence C, C-1, C-2, C-2A, C-2B, C-3, or C-3A district or Business A-2 district if a building is hereafter erected on a lot adjacent to a building having a blank wall directly on the side lot line, the new building may be so designed and erected that it will be flush with that portion of the blank wall of the former building which extends along the lot line; otherwise, however, not less than the required side yard shall be provided; in any case the required side yard shall be provided for the remainder of the full lot depth. In case a side wall contains windows or in case any part of a side blank wall of an existing building shall be set back from the side lot line, then a building hereafter erected on the lot adjacent to such an existing building shall be set back from the side lot line in accordance with the provisions thereof. (a) Measured from the centerline of the street, but in no case may a building be nearer the street line than ten (10) feet. (b) Measured from the centerline of the street, but in no case may a building be nearer to the street line than five (5) feet. (c14) In no case may a non-residential building be nearer the rear lot line than twenty (20) feet. (d) Deleted. (a) In no case may a building be nearer the rear lot line than twenty (20) feet.

MARKUP VERSION -– Additions and creations underlined, deletions in strikethrough Multifamily Housing Zoning Petition – Part One City of Cambridge, MA Page 24 of 70 (d16) Open space requirements for a lot shall be determined by the mix of uses on the lot. Where one hundred (100) percent of the principal uses on a lot are residential uses listed in Subsections 4.31 a, b, d, e, and g, an area equivalent to fifteen (15) percent of the lot area shall be reserved as private open space. Where one hundred (100) percent of the principal uses on the lot are other uses, an area equivalent to fifteen (15) percent of the lot area shall be reserved as publicly beneficial open space. Where development on a lot contains both the aforesaid residential uses and other uses, an area equivalent to fifteen (15) percent of the lot area shall be devoted to both types of open space in relative proportion to the gross floor areas occupied by residential uses and other uses. The amount of each type of open space shall be determined by the formulae below. The results of said formulae notwithstanding, a minimum of fifteen (15) percent of the area of that portion of a lot within forty-five (45) feet of a front lot line facing Green Street shall be devoted to landscaped green space as specified in Subsection 4.27.3. Where more than fifty (50) percent of the area of that portion of a lot is devoted to landscaped green space, as specified in Subsections 4.27.2 and 4.27.3, none of such green space shall be counted in determining compliance with this Subsection 5.332d. Where fifty (50) percent or less of the area of that portion of a lot is devoted to landscaped green space, such area may be counted in determining compliance with this Subsection 5.33 2d. (1a) Minimum required total area reserved for both types of open space = lot area multiplied by .15. (2b) Share of development devoted to residential uses = gross residential floor area divided by gross floor area of entire development. (3c) Minimum required private open space associated with residential use = total open space required multiplied by residential share. (4d) Share of development devoted to other uses = other gross floor area divided by gross floor area of entire development. (5e) Minimum required publicly beneficial open space = total open space requirement multiplied by other use share. (e17) Where any lot abuts a residential district, non-residential buildings above and below ground shall be set back a minimum of twenty (20) feet from the zoning district boundary line, notwithstanding anything to the contrary provided in Article 6.000 of this Ordinance. Said setback shall consist exclusively of landscaped green area as defined in Article 2.000. Where the zoning district boundary line splits a lot the minimum twenty (20) foot setback shall be measured from the lot line(s) located in the residential district. At a minimum green area setback shall consist of permanently maintained, densely planted trees and shrubs that may be expected to form within three (3) years after time of planting a continuous, unbroken, year round visual screen. Every effort shall be made to retain the best existing trees in said setbacks to meet the requirements of this section in whole or in part. Plans for landscaping and maintenance shall be approved by the Committee on Public Planting as appointed by the City Manager. No Certificate of Occupancy may be granted until landscaping under the terms of this section is completed. (f18) Subject to the provisions of Footnote 1 in Section 4.40 - Footnotes to the Table of Use Regulations. (g19) Thirty-five (35) feet [or maximum non-residential height permitted in the abutting residential district, but in no case higher than fifty-five (55) feet] within fifty (50) feet of a residential district line. Where the zoning district boundary splits a lot the fifty (50) feet shall be measured from the lot lines located in the residential district. The height, however, may exceed thirty-five (35) feet provided the non-residential building is set back a minimum distance equal to two-thirds (2/3) the height. (h) Measured from the centerline of the street but in no case may a building be nearer the street than ten (10) feet. (i20) However, for the side yard of any lot abutting another lot (where that lot does not abut Massachusetts Avenue and where all or a majority of it is located in a residence district) no non-residential building shall be set nearer than twenty feet to (1) either the residence/Business A-2 zoning

MARKUP VERSION -– Additions and creations underlined, deletions in strikethrough Multifamily Housing Zoning Petition – Part One City of Cambridge, MA Page 25 of 70 district line where the lot line is located in the BA-2 District or (2) the side lot line itself where that lot line is located in the residence district. Nevertheless, the provisions of the following paragraphfootnote (13) shall continue to apply. If a building is hereafter erected on a lot adjacent to a building having a blank wall directly on the side lot line, the new building may be so designed and erected that it will be flush with that portion of the blank wall of the former building which extends along the lot line; otherwise no less than the required side yard setback shall be provided. In the case that any portion of a side wall of the existing building contains windows or is set back form the property line, then a building hereafter erected on the lot adjacent to such an existing building shall be set back from the side lot line as required. (j21) Or two-thirds (2/3) of the height of the rear wall whichever is greater; however in the Business C and Business C-1 districts no rear yard shall be required where the rear lot line abuts a lot all of which lies in a business or industrial district. (k22) Provided however that any portion of a non-residential building having a height greater than thirty-five (35) feet shall be set back of a bulk control plane rising at an angle of forty-five (45) degree from the plane of the principal front wall and rear wall planes beginning at a height of thirty-five (35) feet. Where the parcel has frontage on two or more streets, this setback plane provision shall apply only to the front wall plane facing the principal abutting arterial street and to the opposite wall plane facing either a side or front property line. In addition to the above provisions, that portion of a non-residential building located within fifty (50) feet of a residential zoning district line shall be limited to thirty-five (35) feet where the maximum non-residential height permitted in the residential district is thirty-five (35) feet or less. (l) The maximum height of a building may be increased to sixty (60) feet provided the average height of the building is fifty (50) feet (excluding any portion of the building devoted to parking which is not covered with building included in gross floor area). The heights of the several parts of the building shall be such that the volume of building exceeding fifty (50) feet in height shall be equal to or less than the volume of space lying between the fifty (50) foot height and portions of building less than fifty (50) feet in height, as illustrated below: Volume 1 (area of a building at a single height - 1 above fifty feet x the difference between height - 1 and fifty feet ) + Volume 2 (area of building at a single height - 2 above fifty feet x the difference between the height - 2 and fifty feet ) MUST EQUAL OR BE LESS THAN THE SUM OF Volume 1' (area of building at a single height - 1' below fifty feet x the difference between height 1' and fifty feet ) + Volume 2' (area of building at single height - 2' below fifty feet x the difference between height - 2' and fifty feet). (m23) Or the setback of the principal front wall plane of any adjacent building facing the same street, whichever is less. (n) Of the total FAR permitted on the lot the maximum ratio of floor area to lot area for permitted principal uses other than residential uses specified in Section 4.31 shall not exceed 2.75. The maximum ratio of floor area to lot area for permitted residential uses specified in Section 4.31 shall be 2.5 as of right; it may be increased to 3.0 and lot area per dwelling unit decreased to three hundred (300) after the issuance of a special permit by the Planning Board provided the following conditions are met: 1. At least seventy-five (75) percent of the gross floor area on the lot is devoted to residential uses specified in Section 4.31. 2. All parking on site is covered and enclosed.

Sites with two front yards that have a radiused front yard where two streets intersect may be considered as if the adjoining property lines are projected to intersect. Projecting bays and roof decks which are located on portions of a non-residential building below thirty-five (35) feet in height shall be eligible for the setback exception allow in Section 5.24.2 even if the structure itself if greater than 35 feet in height. (iii) Building height for a residential or mixed-use structure may be increased to a maximum of forth-four (44) feet. However, for any portion of a structure that abuts a lot in a residential district, the height of the building shall not exceed thirty-five (35) feet within fifteen (15) feet of the lot line. (q25) The following dimensional modifications shall apply in the Business A-5 district: (ia) For any portion of a building within fifty feet (50') of a residential district, the height of that portion of the building shall not exceed thirty- five feet (35'). (iib) The Planning Board may grant a special permit to exclude Retail or Consumer Service Establishments, as listed in Section 4.35 of the Zoning Ordinance, from the calculation of Gross Floor Area (GFA) and Floor Area Ratio (FAR) on the lot if they are located on the Ground Story. The conditions of the special permit shall clearly describe what areas are excluded and what range of uses shall be permitted, along with other conditions to ensure that the objectives of the area are met.

MARKUP VERSION -– Additions and creations underlined, deletions in strikethrough Multifamily Housing Zoning Petition – Part One City of Cambridge, MA Page 34 of 70 (4) A site plan of the development parcel, drawn to scale, showing proposed lot subdivision, if any, the location of proposed buildings, retained and proposed vegetation, location of parking spaces, driveways, proposed curb cuts and walkways, proposed treatment of the perimeter of the parcel including techniques and materials used (screens, fences, walls) and the location of required private open space. (5) Front, side and rear elevations for each structure on the lot indicating building height and heights of buildings on abutting lots. (6) Quantitative data on the proposed development including floor area ratio, floor area per unit, number of bedrooms and the amount of private open space allocated to each unit and reserved for common use of the residents. (7) A list of any zoning violations which would customarily require variances from the requirements of this Ordinance. (8) A Tree Study, certified complete by the City Arborist, as required by the Tree Protection Ordinance of the City of Cambridge, Chapter 8.66. 10.47.2No application shall be accepted by the Planning Board until all of the information required in Subsection 10.47.1 is completed and included in the development plan. Any changes in the development plan by the applicant following submittal of the application, other than those which might be negotiated at the public hearing, shall require resubmittal of an application for a special permit. 10.47.3Upon receipt of the application and development plans, the Planning Board shall transmit forthwith one copy of the plan to the Traffic Department. Within forty-five (45) days of receipt of the plan, the Traffic Department shall review said plan and submit a report and recommendation on the development proposal to the Planning Board.

In reviewing applications for townhouse developments and multifamily dwelling, the special permit granting authority shall consider and address the following site plan criteria as applicable: (1) Key features of the natural landscape should be preserved to the maximum extent feasible. Tree removal should be minimized and other natural features of the site, such as slopes, should be maintained. (2) New buildings should be related sensitively to the existing built environment. The location, orientation and massing of structures in the development should avoid overwhelming the existing buildings in the vicinity of the development. Visual and functional disruptions should be avoided. (3) The location, arrangement, and landscaping of open space should provide some visual benefits to abutters and passersby as well as functional benefits to occupants of the development. (4) Parking areas, internal roadways and access/egress points should be safe and convenient. (5) Parking area landscaping should minimize the intrusion of onsite parking so that it does not substantially detract from the use and enjoyment of either the proposed development or neighboring properties. (6) Service facilities such as trash collection apparatus and utility boxes should be located so that they are convenient for resident, yet unobtrusive. 10.47.41Additional Criteria for Townhouses and Multifamily Dwellings in Industry A and A-2 districts, Industry B, B-1 and B-2 districts, and the Industry C district. In addition to the criteria set forth in Section 10.47.4 above, the following shall be considered by the Planning Board in these industrial districts:

MARKUP VERSION -– Additions and creations underlined, deletions in strikethrough Multifamily Housing Zoning Petition – Part One City of Cambridge, MA Page 35 of 70 (1) On balance the location is appropriate for the proposed residential uses, because: (a) Residential use at the proposed location will not preempt space particularly suitable for nonresidential uses; and (b) Existing or anticipated uses on nearby premises will not make residential use inappropriate because of external impacts such as noise, glare, odors or safety concerns; and (c) The proximity of the proposal to other residential development or reasonably anticipated residential development in the future, helps to establish an amount of housing sufficient to ensure a viable, supportive and healthy residential environment; or (d) The proposal will act as a transition to neighboring residential districts and uses; or (e) The proposal is of sufficient scale to create its own supportive residential environment. (2) The proposed design includes amenities appropriate to provide a supportive service environment for the anticipated residential uses. (3) Other potential benefits can be identified, including: (a) The proposed residential use may make feasible the preservation of an historic structure; (b) The proposed residential use and nearby commercial uses are linked through work/live arrangements or in other ways. Amendments to Article 11.000. Delete Section 11.10 and subsequent subsections as follows: 11.10 DELETEDTOWNHOUSE DEVELOPMENT 11.11Statement of Purpose. This Section 11.10 has been adopted to encourage the development of one and two family townhouses. The townhouse development use created herein is intended to promote development designs that are compatible with traditional neighborhood development patterns and sensitive to existing streetscapes, to encourage a townhouse pattern of development where higher densities are permitted and to discourage the demolition of existing residential structures as well as the excessive infill of townhouses on lots already containing residential structures. Provisions for the townhouse development use are intended to overcome obstacles to the development of one and two family townhouses, by providing special incentives where appropriate. This section provides guidelines for both as of right and townhouse developments which require special permit review. The distinction allows for expeditious review and approvals for smaller scale infill townhouse developments, while ensuring detailed examination of the site and building plans for larger developments and consideration of their neighborhood impacts. 11.12Applicability of Regulations. The development standards specified in this Section 11.10 are applicable only to townhouse developments and do not change the development standards for other uses in the Residence, Office and Business, and Industry A-1 districts. Townhouse developments which meet the requirements specified in Sections 11.14, 11.15, and 11.16 shall be allowed in Residence B, C, C-1, C-1A, C-2, C-2A, C-2B, C-3, C-3A, C-3B, Office and Business and Industry A-1 districts as follows:

MARKUP VERSION -– Additions and creations underlined, deletions in strikethrough Multifamily Housing Zoning Petition – Part One City of Cambridge, MA Page 36 of 70 11.12.1Construction of a townhouse development containing six (6) or more dwelling units in a Residence B district and Residence C district shall require a special permit. 11.12.2Construction of a townhouse development containing twelve (12) or more dwelling units in a Residence C-1, Residence C-1A, Office 1, Office 2, Business A-1, Industry A-1 or Business A-3 district shall require a special permit. 11.12.3Construction of a townhouse development in a Residence B, C, C-1, Residence C-1A, Office 1, Business A-1 or Business A-3 district which contains fewer units than specified in Section 11.12.1 or 11.12.2 shall require a special permit if both of the following conditions pertain to the development: (1) Another permit for townhouse development has been granted within the twelve (12) month period immediately preceding the date of permit application for the lot on which the development would be located or on an abutting lot; (2) The townhouse development for which the permit is being sought would increase the total number of dwelling units on said lot(s) to the threshold specified in Section 11.12.1 or 11.12.2. 11.12.4Construction of all townhouse development in Industry A and A-2 districts, Industry B, B-1 and B-2 district, and the Industry C district shall require a special permit granted by the Planning Board where any one of the following conditions exist: 1) The development exceeds fifty thousand (50,000) square feet of gross floor area; 2) The lot area per dwelling unit proposed is less than one thousand two hundred (1,200) square feet in an Industry C district six hundred (600) square feet in an Industry A district, or three hundred (300) square feet in an Industry A-2, Industry B, or Industry B-1 district; or 3) Twelve units or more dwelling units are proposed where any portion of the development is located within one hundred (100) feet or a Residence A- 1, A-2, B, C, or C-1 district. 11.12.5Where a townhouse development is constructed on two or more abutting lots, the requirements applicable to the development shall be determined as if the parcel were a single lot. 11.12.6Where a townhouse development is constructed on a lot or lots with other buildings existing prior to such development, the dimensional requirements of this Section 11.10 shall apply to those structures or portions of structures on the lot(s) which constitute the townhouse development. 11.12.7Where a townhouse development is proposed on a lot on which a preferably preserved significant building, as determined by the Cambridge Historical Commission under the provisions of the Demolition Ordinance #965, has been demolished within the five (5) years immediately preceding the application for a building permit or a special permit or where such building is proposed to be demolished to permit the townhouse development under the provisions of this Section 11.10, the provisions of Subsections 11.14, 11.15, and 11.15.1 - 11.15.4 shall not apply; the townhouse development shall in such circumstances be subject to the dimensional requirements normally applicable in the district. 11.13Special Permit Granting Authority. The Planning Board shall be the special permit granting authority for any townhouse development included in Section 11.12.1, 11.12.2, or 11.12.3. The Board of Zoning Appeal shall be the special permit granting authority for special permits required by Sections 11.15.5, 11.16.2, and 11.16.4 for any townhouse development which does not require a special permit from the Planning Board. 11.14Subdivided Lots. A developer, or any subsequent owner, who desires to subdivide a townhouse development must record a subdivision plan with the Registry of Deeds of Middlesex County. A copy of the recorded subdivision plan must also be filed with the Building Commissioner. Subdivided lots may

MARKUP VERSION -– Additions and creations underlined, deletions in strikethrough Multifamily Housing Zoning Petition – Part One City of Cambridge, MA Page 37 of 70 be less than five thousand (5,000) square feet and must include an individual dwelling, together with front and rear yards or rights to yards in common areas. 11.15Dimensional Standards for Townhouse Development. The following development controls apply to the parcel of land upon which a townhouse development is constructed and are not applicable to the initial subdivision of the townhouse parcel into individual lots. The townhouse development parcel as a whole must conform to these controls. But once satisfied for the total parcel, the controls are waived for the subsequent subdivision into individual lots. The required minimum lot size for a townhouse development shall conform to the existing regulations for the district in which the townhouse development is constructed. However, modifications to the townhouse development after a subdivision plan has been recorded in the Registry of Deeds shall be subject to the dimensional standards as set forth in this Section 11.15 applied to the individual lot lines of the subdivided lots; modifications that do not so conform may be permitted as set forth below: a. For any townhouse development, after issuance of a building permit, projecting eaves, chimneys, bay windows, and balconies that do not project more than three and one half (3 1/2) feet. b. For any townhouse development for which a special permit has been granted by the Planning Board, modifications specifically enumerated in the special permit. For those modifications not so enumerated, or where the special permit fails to specifically enumerate allowed modifications, after issuance of a new special permit (a Major Amendment to the original special permit) by the Planning Board to allow the proposed modification(s). c. For any townhouse development originally constructed as of right, after issuance of a special permit by the Board of Zoning Appeal. Where a special permit is required in paragraphs b. and c. above, all owners of lots that together constitute the original townhouse development parcel shall receive notice of the special permit public hearing, in the manner provided for in Chapter 40A for parties of interest; such owners shall be considered parties in interest, however, only as they are so defined in Section 11, Chapter 40A. 11.15.1Minimum Lot Width. In a townhouse development there shall be no minimum lot width, except that in Residence B, Residence C, and Residence C-1 districts the minimum lot width applicable in the district shall apply. 11.15.2Maximum Floor Area Ratio. In a townhouse development, the maximum permitted floor area ratio in districts where townhouse developments are permitted shall be as normally applicable in the district. 11.15.3Maximum Height. In a townhouse development the maximum permitted height shall be four habitable stories and the maximum height of the cornice line shall be thirty (30) feet. Any part of a townhouse structure which projects above the cornice line shall be set below an imaginary inclined plane beginning at the thirty (30) foot cornice line on any facade of the structure facing a street or facing any lot line abutting a residentially zoned lot, and thereafter rising at a forty-five degree (45°) angle. However, portions of the building may rise above the imaginary inclined plane provided the area of those portions above the inclined plane projected onto the vertical plane does not exceed ten (10) percent of the area of the vertical plane lying between the thirty (30) foot cornice line and the maximum height of the structure, calculated for and limited to each separate plane. However, the maximum height of any portion of a townhouse development shall be forty (40) feet, except that in a Residence B district the maximum height shall be thirty-five (35) feet.

MARKUP VERSION -– Additions and creations underlined, deletions in strikethrough Multifamily Housing Zoning Petition – Part One City of Cambridge, MA Page 38 of 70 11.15.31In any zoning district that limits building height to thirty-five (35) feet or less, the maximum permitted height in a Townhouse Development shall be thirty-five (35) feet. 11.15.32In all other districts the maximum permitted height in a townhouse development shall be four habitable stores and the maximum height of the cornice line shall be thirty (30) feet. Any part of a townhouse structure which projects above the cornice line shall be set below an imaginary inclined plane beginning at the thirty (30) cornice line on any façade of the structure facing a street or facing any lot line abutting a residentially zoned lot, and thereafter rising at a forty-five (45) degree angle. However, portions of the building may rise above the imaginary inclined plane provided the are of those portions above the inclined plane projected into the vertical plane does not exceed ten (10) percent of the area of the vertical plane lying between the thirty (30) foot cornice line and the maximum height of the structure, calculated for and limited to each separate plane. However, the maximum height of any portion of a townhouse development shall be forty (40) feet, except that in a Residence B district the maximum height shall be thirty-five (35) feet. 11.15.4Yard Requirements. The yard requirements in the district shall be applicable for each townhouse development. 11.15.5Minimum Private Open Space. In a townhouse development the minimum ratio of private open space as defined in Article 2.000 to lot area shall be twenty-five (25) percent or that amount required in the district, whichever is greater. (1) The minimum dimension of any area counted toward required private open space shall be fifteen (15) feet. A ten (10) foot minimum open space dimension may be allowed on special permit by the Special Permit Granting Authority upon its determination that the peculiarities of the parcel warrant such a reduction, that the smaller dimension will result in a superior site design, and that the total amount of private open space will not be reduced. (2) Where it is proposed to subdivide a townhouse development in accordance with the requirements of Section 11.14 then the minimum ratio of private open space to subdivided lot area shall be that required for the Townhouse Development as a whole. Where the townhouse development is not to be subdivided into individual lots and therefore the private open space in a townhouse development is not to be provided on subdivided lots but is to be provided on a common basis to be held in joint ownership by a group of townhouse owners such as a cooperative or an association, then the minimum ratio of private space to the total lot area in the townhouse development shall be that required in this Section 11.15.5. 11.16Parking Standards for Townhouse Development. A Townhouse Development shall be subject to the requirements of Article 6.000 except as they may be modified below. 11.16.1One off street parking space per dwelling unit in a townhouse development shall be provided unless a special permit is granted in accordance with Section 11.16.2(4) below. 11.16.2Required parking spaces may be located as follows: (1) Within the townhouse structure or a separate structure on the parcel. (2) On a lot in accordance with the requirements of Sections 6.20 and 6.40. (3) On lots not more than two hundred (200) feet away from the building to be served subject to the conditions set forth in Sections 6.20 and 6.40.

MARKUP VERSION -– Additions and creations underlined, deletions in strikethrough Multifamily Housing Zoning Petition – Part One City of Cambridge, MA Page 39 of 70 (4) On street in the vicinity of the townhouses if the special permit granting authority determines that the lack of off street parking for the townhouse development will not unreasonably reduce the quantity of on street parking in the area. Applicants for an exception from off street parking shall submit a report on parking usage and availability in the vicinity of the development with their permit application. 11.16.3Landscaping of On Grade Open Parking. (1) On grade open parking areas should be arranged and landscaped to properly screen cars from adjacent properties as well as from streets and sidewalks and to diminish the negative environmental impacts of multiple automobiles parked on site in residential neighborhoods. (2) Twenty-five (25) percent of the area devoted to on grade open parking shall be landscaped. The area devoted to on grade open parking shall be that portion of the lot containing parking spaces, driveways, and landscaped area located between or adjacent to parking spaces and drives. No portion of the lot required as a setback between a parking space and a building or a lot line shall be counted in computing the twenty-five (25) percent landscaping requirement. (3) Where more than one "area devoted to on grade open parking" exists within a townhouse development twenty-five (25) percent of each such area shall be landscaped. (4) For every two (2) on grade open parking spaces or fraction thereof there shall be a minimum of one three (3) inch caliper tree located within the area devoted to on grade open parking. (a) The special permit granting authority may grant a special permit for a reduction of this planting requirement upon its determination that such a reduction will not prevent suitable screening of on grade parking and will result in a superior site plan. Any reduction shall require a special permit. (b) The trees required for the landscaping of on site parking areas - whether such trees are coniferous or deciduous, flowering or nonflowering - should be tolerant to urban environmental conditions; able to screen parking areas by virtue of their size, form, density of foliage and spread; and easy to maintain. A suggested list of trees which meet these criteria is: Deciduous. Botanical name (common name) Acer platanoides (Norway Maple); Acer rubrum (Red Maple); Acer saccharum (Sugar Maple); Carpinus betulus (European Hornbeam); Fraxinus americana (White Ash); Ginkgo biloba (Ginkgo); Gledistsia triacanthos inermis (Thornless Honey Locusts); Liquidambar styraciflua (Sweet Gum); Liriodendron tulipfera (Tulip Tree); Platanus occidentlis (Syamore); Quercus coccinea (Scarlet Oak); Quercus palustris (Pin Oak); Quercus rubra (Red Oak); Tilia cordate greenspire (Littleleaf Linden); Tilia europea (Common Linden). (5) On grade open parking areas located in front of the townhouse structure(s) shall maintain the visual definition of the front lot line and separation of public from private space in keeping with the appearance and character of the existing streetscape. Such definition shall be achieved by using a change of ground materials at the front lot line and by installing at least one of the following: fences, plantings, walls, or stone monuments which mark the transition from street or sidewalk to residential lot. 11.17Additional Requirements. (1) Fences may not exceed four (4) feet in height in any front yard unless otherwise permitted by the special permit granting authority.
