CAMBRIDGE CITY COUNCIL Quinton Zondervan City Councillor To: ​Paula Crane, Interim City Clerk From: ​Quinton Y. Zondervan, City Councillor Date: ​July 30, 2019 Subject: ​Memorandum Submission Please place the attached memorandum, “AHO Amendments from Councillor Zondervan” on the City Council agenda as “Late Communications and Reports from Other City Officials” for the July 30, 2019 meeting. Thank you, Councillor Quinton Y. Zondervan 1

CAMBRIDGE CITY COUNCIL Quinton Zondervan City Councillor MEMORANDUM To: ​Cambridge City Council From: ​Quinton Y. Zondervan, ​City Councillor Date: ​July 30, 2019 Subject: ​AHO Amendments from Councillor Zondervan AHO Amendments from Councillor Zondervan Introduction With nearly 20,000 individuals and families on the housing waitlist, it is frustrating to have spent most of the term and so much energy on a proposal that will lead to a few hundred additional units (at best) over the next decade, beyond what would have otherwise been built. Nobody disagrees that our zoning code could use a citywide overhaul, and the conclusion of the Envision master plan process seems to be a great time to do it. But this proposal takes a very narrow lens to that task, and for all the controversy, it seems likely that it will not meaningfully address the problem at hand. Ultimately, we will need to be much bolder in our approach if we truly want to make a difference. Nonetheless, the AHO is before us and it is our duty as a council to carefully weigh the costs and benefits and to improve it as best we can before finally making a decision. I have listened to the perspectives of hundreds of constituents on this issue, and I have taken the time to seek out voices we don’t often hear from. A few themes have emerged from these conversations, which I have done my best to capture in the attached amendments for your consideration. 2

CAMBRIDGE CITY COUNCIL Quinton Zondervan City Councillor In order for me to support an as-of-right citywide rezoning, there are three critical points I will be considering: 1. We must protect existing tenants from displacement, and we must protect our local businesses as well. 2. We must build with the climate crisis in mind, and that means anything we build should not be making global warming worse, and should protect the health and safety of its occupants from the impacts of climate change. 3. We must be assured that the resulting buildings will be of the highest quality, that they will meet the architectural and design standards that we expect, and that they will serve the needs of the occupants. This is by no means a final or exhaustive list of changes that will be required, and we are very much still at the beginning of the conversation in terms of evaluating whether or not the AHO is a good idea for Cambridge. The question does not hinge on the severity of the housing affordability crisis, which is high, but on the expected benefits of the policy proposed to address it. Whether or not we approve the AHO, we still have a lot more work to do in meeting the twin challenges of housing our residents affordably and protecting ourselves from climate change. That is why I am an outspoken supporter of Representative Connolly’s Housing for All agenda, and that is also why I will be introducing a bolder series of reforms this fall, including a ban on fracked gas in new construction and a proposal to allow multifamily housing everywhere in our city. Summary of Zondervan Amendments 1. I was glad to receive the latest AHO design guidelines from CDD yesterday. While these are a good start, a great deal more work remains to be done before these guidelines can be considered an acceptable tradeoff for eliminating discretionary project design review. I look forward to the continuing development of these guidelines. 3

CAMBRIDGE CITY COUNCIL Quinton Zondervan City Councillor 2. Any tenant directly displaced by an AHO construction must be guaranteed a right to return. (Definitions, 3.b.iv) 3. For AHO units, we should give preference to those who have experienced a no-fault eviction from a market unit within city limits within the past year. (3.b.i) 4. AHO construction should not be exempt from the ​Tree Protection Ordinance​. This is a fundamental matter of equity; everyone deserves access to the health and safety benefits of trees in close proximity to their dwelling units. The Affordable Housing Trust Fund should cover any additional costs incurred while achieving these standards, so that compliance won’t limit or prevent affordable housing construction. (7.6) 5. AHO buildings must be built ​Net Zero Ready​ (Definitions)​,​ which means: as energy efficient as possible, with no on-site fossil fuel combustion, and maximum on-site solar production (if technically feasible), geothermal or air-source heating & cooling, and rainwater capture. (7.6) 6. FAR (density) should be limited to ensure sufficient land area for green open space for residents to enjoy and to protect against the heat and flooding impacts of climate change. (7.6.d) 7. Protect existing retail in buildings that are rebuilt/refurbished under the AHO. (4.b.i) 8. Allow retail services in any AHO building. (4.b) 9. 20% of GFA should be set aside explicitly for homeownership purposes in projects greater than 10 units. We could put these units directly into the city’s Homeownership Resale Pool, so there would be no additional administrative overhead. (3.b.iii) 10. Off-street surface parking cannot be counted as part of the 30% minimum open space requirement. (5.2.3.a.i) 4

CAMBRIDGE CITY COUNCIL Quinton Zondervan City Councillor 11. 100% of the required open space shall meet the city’s definition of permeable. (5.2.3.c) 12. Waive the minimum lot area per dwelling unit dimensional requirement in table 5-1 to allow multiple dwelling units on a site. (4.a). 13. We should completely eliminate parking minimum requirements for AHO construction, with the only exceptions being to provide sufficient accessible parking as well as ample space for pickup and dropoff. Developers would still be allowed to build parking, but they wouldn’t be required to do so.

CAMBRIDGE CITY COUNCIL Quinton Zondervan City Councillor elsewhere in the Zoning Ordinance shall not apply if the following standards are met; however, the design standards specific to the project area are encouraged to be met to the extent possible if they are not in conflict with the purpose of this Section. (b) The following design standards shall apply to new construction and to additions to existing structures. Except as otherwise provided, an existing building that is altered or moved to accommodate an AHO Project shall not be subject to the following standards, provided that such alterations do not create a condition that is in greater nonconformance with such standards than the existing condition. 7.2 Site Design and Arrangement (a) The area directly between the front lot line and the principal wall plane of the building nearest to the front lot line shall consist of any combination of landscaped area, hardscaped area accessible to pedestrians and bicyclists, and usable spaces such as uncovered porches, patios, or balconies. Parking and other motor vehicle uses, including service and loading facilities, shall not be located within such area, except for driveway access which shall be limited to a total of thirty (30) feet of width for any individual driveway for each one hundred (100) feet of lot frontage. (b) Pedestrian entrances to buildings shall be visible from the street, except where the building itself is not visible from the street due to its location. All pedestrian entrances shall be accessible by way of access routes that are separated from motor vehicle access drives. (c) A building footprint exceeding 250 feet in length, measured parallel to the street, shall contain portions that are set back by at least 40 feet in depth measured from and perpendicular to the front lot line and at least 40 feet in width measured parallel to the front lot line. 7.3 Buildings Façades​ (a) At least 15% of the area of building façades facing a public street or public open space shall consist of clear glass windows. For buildings located in a Business A (BA), Business A-2 (BA- 2), Business B (BB) or Business C (BC) zoning district, this figure shall be increased to 25%. 18

CAMBRIDGE CITY COUNCIL Quinton Zondervan City Councillor (b) Building façades shall incorporate architectural elements that project or recess by at least two feet from the adjacent section of the façade. Such projecting or recessed elements shall occur on an average interval of 40 linear horizontal feet or less for portions of the façade directly facing a public street, and on an average interval of 80 linear horizontal feet or less for other portions of the façade. Such projecting or recessed elements shall not be required on the lowest Story Above Grade or on the highest Story Above Grade, and shall not be required on the highest two Stories Above Grade of a building containing at least six Stories Above Grade. The intent is to incorporate elements such as bays, balconies, cornices, shading devices, or similar architectural elements that promote visual interest and residential character, and to allow variation at the ground floor and on upper floors where a different architectural treatment may be preferable. (c) To provide additional visual interest to the façade, for window openings above the ground floor facing a public street or public open space, the developer is encouraged to include architectural elements that provide depth and/or surface relief such as recessed or projecting window surfaces, sills, sun shades, or shutters. 7.4 Ground Floors (a) The elevation at floor level of the ground floor of a building, meaning the lowest story above Grade, shall be at the mean Grade of the abutting public sidewalk, or above such mean Grade by not more than four feet. Where active non-residential uses are provided at the ground floor, the ground floor shall be accessible directly from the sidewalk without requiring use of stairs or a lift. The requirements of this paragraph shall not apply if it is determined by the City Engineer that a higher ground floor elevation is necessary for the purpose of flood protection.
