Amend Section 19.40 and subsequent subsections, including the creation of a new subsection 19.47, to read as follows: 19.40 CITYWIDE ADVISORY DEVELOPMENT CONSULTATION PROCEDURES 19.41General Purpose. This Section 19.40 provides the opportunity for City staff and the general public (1) to review and comment on development proposals prior to the formulation of final plans and before the issuance of a building permit and (2) to determine compliance with the zoning requirements applicable to the development. Each application for a building permit for one of the categories of development specified in Sections 19.42 and 19.43 shall be accompanied by a written certification from the Cambridge Community Development Department (CDD) indicating that the applicant has participated in the Development Consultation Procedure specified in this Section 19.40, for the proposal for which the permit is being sought. In each instance where the application for a building permit occurs more than six (6) months after the consultation session, CDD shall additionally certify to the Superintendent of Buildings whether the plans submitted for a building permit are consistent with those reviewed at the consultation session, and if not how they differ. Unless otherwise indicated elsewhere in the Zoning Ordinance, the Community Development Department shall conduct the consultation session. No certification pursuant to provisions of this Section 19.40 shall be deemed to be in lieu of the responsibility of the Superintendent of Buildings to enforce all provisions of the Zoning Ordinance - each Certificate of Compliance is advisory to the applicant and the Superintendent of Buildings. The failure of CDD to hold the consultation session or to issue the Certificate of Compliance within the review time periods specified in this Section shall not prevent an applicant for a building permit from receiving such permit after such time period has expired. 19.41.1 Types of Advisory Development Consultations a. Staff Advisory Consultations are intended for City staff from CDD and other departments with relevant expertise to discuss requirements and City standards that will be applicable to the project and to provide non-binding comments on the project’s conformance with the Citywide Urban Design Objectives and design objectives specific to an area. The process is informal with few requirements for submission. b. Public Advisory Consultations are intended for members of the public to learn about a proposed development and provide non-binding input directly to the developer, sometimes through an

MARKUP VERSION Multifamily Housing Zoning Petition – Part Two – As Adopted by City Council 2/10/2025 City of Cambridge, MA Page 12 of 21 appointed Advisory Committee which makes a report. The process is more structured with requirements for materials submission, scheduling and notification. c. Planning Board Advisory Consultations are intended to provide a forum for input from the public, city staff, and the Planning Board through a process similar to a special permit hearing but not resulting in an approval or denial of permits for the proposed development. 19.42Staff Advisory Consultation Procedure. 19.42.1Applicability of Staff Advisory Consultation Procedure. a. For those zoning districts identified in Section 19.46 as Areas of Special Planning Concern, the following types of development proposals shall be subject to the Staff Advisory Consultation Procedure (unless the regulations for an individual Area of Special Planning Concern provide for specific exceptions or additional types): (1) Construction of any new building having a gross floor area of less than two thousand (2,000) square feet devoted to uses other than Residences listed in Section 4.31 a-j.; (2) Construction of any other new structure having a floor area of less than two thousand (2,000) square feet devoted to uses other than Residences listed in Section 4.31 a-j.; (3) Any exterior building alteration increasing gross floor area by one hundred (100) square feet or more; or (4) Construction of five or more parking spaces, whether on grade or in a structure. b. Where a Staff Advisory Consultation is not required by Paragraph b. above, it shall be required if the development is subject to the Building and Site Plan Requirements in Section 19.50. c. A Staff Advisory Consultation may be requested voluntarily for any development proposal, and is strongly encouraged for any development before requesting a Public or Planning Board Advisory Consultation procedure and before applying for any special permit from the Planning Board. 19.42.2Request for a Staff Advisory Consultation. Prior to application for a building permit, the applicant shall contact CDD and request a development consultation session. Upon making such a request, the applicant shall present for review such written or graphic materials necessary to give a reasonably complete, though not necessarily detailed, indication of the nature and scope of the development proposal. For projects that involve the construction of a new building or an addition to a building on a new foundation, for advisory purposes only, the materials should include those required by the Flood Resilience standards set forth in Section 22.80 and the Green Factor standards set forth in Section 22.90. For projects that involve an increase in the amount or area of surface parking, or a decrease in the amount of open space provided, the materials should include those required by the Green Factor standards set forth in Section 22.90. The consultation session shall occur no later than ten business days after the request for such a consultation, unless a longer timeframe is mutually agreed to by the developer and CDD. 19.42.3Completion of the Staff Consultation. In most cases CDD and other City staff will provide feedback during the consultation session and will discuss with the developer if further review will be needed to determine compliance with applicable standards. Where the Staff Advisory Consultation is required, the final staff comments and the issuance of the Certificate of compliance shall be made within ten business days of the consultation session, unless a longer timeframe is mutually agreed to by the developer and CDD. 19.43Public Advisory Consultation Procedure. 19.43.1Applicability of Public Advisory Consultation Procedure. For those zoning districts identified in Section 19.46 as Areas of Special Planning Concern, any development proposal involving the construction of a new building or new structure or an alteration of an existing building or structure that increases the gross floor by

MARKUP VERSION Multifamily Housing Zoning Petition – Part Two – As Adopted by City Council 2/10/2025 City of Cambridge, MA Page 13 of 21 two thousand (2,000) square feet but does not require a Planning Board Advisory Consultation or a special permit from the Planning Board. 19.43.2Application for a Public Advisory Consultation. Prior to application for a building permit, the applicant shall submit the following materials to CDD for its review. The written and graphic materials listed below shall give a reasonably complete indication of the nature and scope of the development proposal. Each of the following shall be submitted as appropriate to the proposal: (1) A site plan indicating the general location and boundaries of the lot, major anticipated changes in natural features, existing and proposed buildings, publicly beneficial open space and/or useable beneficial open space and/or private open space, existing and proposed curb cuts, off street parking areas, loading and service facilities, and generalized landscaping scheme or other anticipated treatment of open spaces. (2) Cross section(s), generalized floor plans and other diagram(s) indicating the anticipated locations of various land uses within the building and on the site and major pedestrian pathways. (3) Architectural elevations or sketches indicating anticipated facade treatment along public ways including the proposed entrances, fenestration, and signage. (4) A summary indicating compliance with applicable zoning requirements. (5) For projects that involve the construction of a new building or an addition to a building on a new foundation, materials identified in the Flood Resilience standards set forth in Section 22.80 shall be submitted to CDD for review and approval. If Section 22.80 is not applicable to the project, the materials shall nonetheless be provided for advisory purposes. (6) For projects that involve the construction of a new building, enlargement of an existing building footprint, increase in the amount or area of surface parking, or decrease in the amount of open space provided, materials identified in the Green Factor standards set forth in Section 22.90 shall be submitted to CDD for review and approval. If Section 22.90 is not applicable to the project, the materials shall nonetheless be provided for advisory purposes. 19.43.3Conduct of the Public Advisory Consultation. Abutters and representatives of various agencies and interest groups shall be invited to participate in a consultation session for proposals submitted for review in accordance with Section 19.43.2. Where an advisory committee has been established in this Zoning Ordinance for the area where the proposal is located (for example, the Harvard Square Overlay District or Central Square Overlay District), the consultation session shall be held at a public meeting of that advisory committee. Otherwise, CDD shall schedule a public meeting and give notification of any scheduled development consultation to each abutting property owner and to any individual or organization who each year files with CDD a written request for such notification, or to any other individual or organization CDD may wish to notify. Within twenty (20) business days of submittal of the application documents, or at a regularly scheduled meeting of an advisory committee if applicable, the Department will schedule and hold a consultation session with the applicant or the applicant’s representatives and any parties listed in this Section 19.43.3. Within ten (10) days of the consultation session, CDD shall issue to the applicant written comments on the development proposal as expressed by City staff and others in attendance, which shall constitute the Certificate of Compliance. Timeframes may be extended by mutual agreement of the applicant and CDD. CDD may seek the advice and assistance of other City departments and of the organizations given notice of the consultation procedure in reviewing a development proposal. 19.43.4Review Criteria and Required Findings of the Public Advisory Consultation Procedure. In reviewing each application, CDD shall: (1) Evaluate the proposal for general compliance with zoning requirements, for consistency with City development guidelines prepared for the proposal area, for appropriateness in terms of other planned or programmed public or private development activities in the vicinity and for consistency with the

MARKUP VERSION Multifamily Housing Zoning Petition – Part Two – As Adopted by City Council 2/10/2025 City of Cambridge, MA Page 14 of 21 Citywide Urban Design Objectives set forth in Section 19.30. The Department shall consider the proposal in terms of the specific and general impact of the use and/or dimensions proposed therein on the area of special planning concern and on adjacent neighborhoods and shall further take account of the following considerations: scale, bulk, density, aesthetic qualities, land use, traffic impacts and other functional characteristics; parking and loading; and impact on public services and facilities. (a) AddiƟonal Criteria in Business A-4 District Ground Floor Retail uses of less than 2,000 square feet which will serve as an amenity for the surrounding residenƟal neighborhood should be included in any building greater than 20,000 square feet. (2) Make recommendations in a written report to the applicant including general approval or disapproval of the proposal and in connection therewith may suggest specific project adjustments and alterations to further the purposes of this Ordinance. 19.44The Memorandum of Understanding ("MOU") dated October 5, 2015, signed by Eric Hoagland on behalf of Observatory Hill Apartments, LLC (the "LLC"), acting on behalf of the LLC as developer of the proposed development at 253 Walden Street, identified as Map 272, Lot 17 in the records of the City of Cambridge (the "Project"), and the Neighborhood Review Committee ("NRC"), consisting of residents of the surrounding community , is incorporated by reference hereto and shall be binding upon the Project as set forth in the MOU.
