The citizen participation process including presentations, discussions, public hearings, letters and comments has been long and arduous. The issues are complicated and sometimes feelings run high. In such situations, there can be a feeling that citizens have not been heard. This document, “Guide to Zoning Amendments Related to Multifamily Uses and Mixed-Use“, summarizes many of the issues that have been raised and the changes that have been made in the zoning Articles as a result of the citizen participation in the public review process. Citizens have been heard.

Some years back, I took a bus ride to a climate rally in New York City with a bunch of other activists. My seatmate was 12 years old, a smart kid from the suburbs who had never been to New York. As we approached Manhattan on the Cross Bronx Expressway, he looked out at a block of concrete apartment buildings and said something like: This is what happens when you don’t care about the environment. Actually, I replied, this is green living: People live close together; they can walk or take public transit; they live in apartments, share walls and heat and are relatively energy efficient; their carbon footprint is far lower than a family in a “green”, leafy single-family suburban house.
But my traveling companion was not altogether wrong about what he saw: New York, Boston, and every other city are now at pains to make a humane, equitable adaptation to a changing climate. We don’t want to create living spaces that bake in the sun’s heat, that have no shade or greenery or open space, surrounded by asphalt and highway, beset with deadly particulate pollution, flooding risk, and polluted stormwater runoff. Heat and air pollution are an expensive and deadly burden that fall especially heavily on low- and middle-income folks — a burden cruelly increasing with climate change.
As we decide what kinds of housing we are going to encourage in Arlington, we can do things in a more compassionate and inclusive way. We can incorporate environmental and aesthetic concerns, while allowing a mix of housing types that accommodate people of diverse incomes, family sizes, and life stages.
We can address both the climate crisis and the crisis-level housing shortage in Greater Boston. Environmental concerns are not a reason to say no to new housing. Rather, they are a part of the housing solution, in Arlington and regionally.
As Laura Wiener detailed in another post, The Housing Corporation of Arlington development at 10 Sunnyside (between Broadway and Mystic Valley Parkway, near Route 16), is an excellent example of implementing environmental/sustainability measures in an affordable (i.e. income-subsidized) multi-family dwelling. It is Passive House certified: An extremely stringent standard, using a combination of advanced and repurposed materials, high- and low-tech, to provide human comfort while bringing energy use to an absolute minimum.* The development features plentiful bike parking and a roof garden. It converts previously impervious pavement to landscaping, like planters, where stormwater can infiltrate the ground rather than carrying unfiltered pollutants into Arlington’s water bodies.
Another example of green infrastructure lives charmingly and unassumingly on some of our street corners. In 2020, Arlington installed rain gardens at the corner of Milton Street and Herbert Road in East Arlington. These little curbside oases act as a kind of green filter for storm water, catching pollutants (Fertilizer! Salt! Dog poop! Oil! Brake dust!) before they reach Alewife Brook and the Mystic River. Perhaps co-sited with new housing, wider buildout of rain gardens could keep nutrient pollution out of Spy Pond, preventing nasty algae growth which literally suffocates other aquatic life.
A caveat: We must take care not to load so many creative requirements onto new housing that it doesn’t get built at all. We need the housing. (See “The Problem with Everything-Bagel Liberalism” by Ezra Klein in the New York Times.) And under the new MBTA Zoning that we are required to implement, we must allow three-family housing in our new multi-family zones by right, i.e. without extra requirements or rigamarole.
But we could decide to add incentives to allow more housing above those requirements if such environmental improvements (rain gardens, green roofs, pollinator habitat, Passive House innovations, etc.) are included. Every new building is an opportunity for environmental adaptation. A vision for a greener, cooler, more inclusive Arlington takes shape. We can do this.
New housing development provides an opportunity to incorporate inclusive, environmentally friendly, win-win adaptations. Our environmental and housing goals must not be in tension with each other. With a coordinated approach, we can address the challenges of pollution, climate change, and our chronic and unjust housing shortage.
*As far as I can tell, only two other buildings in all of Greater Boston are Passive House certified: A new multi-family in Roxbury, and a single-family in Somerville.
(This post was originally an email message, discussion open space changes proposed by an Affordable Housing article during the Arlington, MA’s 2019 town meeting. It’s also a decent description of our town’s open space laws.)
Sorry this turned out to be a long post. Our open space laws are kind of complicated.
Arlington regulates open space as a percentage of gross floor area, rather than as a percentage of lot area. Let me give a concrete example: say we have a-one story structure with no basement. It covers a certain percentage of the lot area, and has an open space requirement based on the gross floor area (i.e., the interior square footage of the building).
Now, suppose we want to turn this into a two- or three-story structure. The building footprint does not change, and it covers exactly the same percentage of the lot area. However, the open space requirements double (if you’re doing a two-story building), or triple (if you’re doing a three story building). If that quantity of open space isn’t on the lot, then you can’t add the stories.
For this reason, I’d argue that our open space regulations are primarily oriented to limiting the size of buildings. You really can’t allow more density (or taller buildings) without reducing the open space requirements. Alternatively, if the requirements were based on a percentage of lot area, we probably wouldn’t need a reduction. (Cambridge’s equivalent is “Private Open Space”, and they regulate it as a percentage of lot area.)
The other weird thing about our open space laws is that we define “usable open space” in such a way that it’s possible to have none. (Usable open space must have a minimum horizontal dimension of 25′, a grade of 8% or less, and be free of parking and vehicular traffic). I live on a nonconforming lot that does not meet these requirements, as do the majority of homes in my neighborhood.
Suppose I wanted to build an addition, which would increase the gross floor area. With the non-conformity, I’d have to go in front of the ZBA and show that the current lot has 0% usable open space, and that the house + addition produces a lot with 0% usable open space. Because 0% = 0%, I have not increased the nonconformity, and would be able to build the addition, provided that all of the other dimensional constraints of the bylaw are satisified. Although this isn’t directly related to Article 16, it’s an amusing side effect of how the bylaw is written.
Finally, roofs and balconies. Section 5.3.19 of our current ZBL allows usable open space on balconies at least six feet wide, and on roofs that are no more than 10′ above the lowest occupied floor. We allow 50% of usable open space requirements to be satisfied in this manner.
The relevant section of Article 16 would create a 8.2.4(C)(1) which includes the language
Up to 25% of the landscaped open space may include balconies at least 5 feet by 8 feet in size only accessible through a dwelling unit and developed for the use of the occupant of such dwelling unit.
Article 16’s incentive bonuses strike the usable open space requirement, and double the landscaped open space requirement. With only landscaped open space, 5.3.19 doesn’t apply (it only pertains to usable open space). The language I’ve quoted adds something 5.3.19-like, but for landscaped open space. I say 5.3.19-like because it has a 25% cap rather than a 50% cap, and requires eligible balconies to be at least 5’x8′, rather than 6′ wide.
Here are a few pieces of supporting documentation:
- definitions of landscaped and usable open space from our ZBL
- a diagram to illustrate the difference between landscaped and usable open space.
- The text of section 5.3.19 (which is referenced by the diagram)
- the main motion for Article 16

If you’ve lived in Arlington for a while, your housing costs, whether you rent or own, might be well below what they are for newcomers. Perhaps you, or someone you know is experiencing scary annual rent increases, or would like to buy a house but can’t get near Arlington’s $1 million-plus median price tag.
Arlington, and much of the Commonwealth, has a shortage of housing that is driving up housing prices and increasing homelessness. Renters are particularly hard hit, with median rents over $2500/month. About 1/3 of Arlington’s renters pay more than 30% of their income for housing. In order to get that rent down to something affordable for a low-income household, subsidies are needed. Arlington has been very supportive of building affordable housing, using its CDBG (Federal Community Development Block Grant) and CPA (local Community Preservation Act) funds to that end. It has also worked cooperatively with the Arlington Housing Authority and Housing Corporation of Arlington in support of their affordable housing projects. These subsidy dollars are necessary but not sufficient for building affordable housing.
Land cost is one thing that makes building any housing expensive, and one way to decrease the cost of building affordable housing is to allow more units to be built on a given piece of land. But our zoning limits much of our town to single- and two-family homes on a lot. The Affordable Housing Overlay allows more units to be built on a lot, throughout the Town, and targets those who need it most—low-income households.
A zoning overlay is an alternative set of zoning requirements that can be applied on a piece of land. A builder can choose to build under the alternative Overlay Zoning rules, or under the original zoning, known as the Underlying Zoning. In this case, the proposed Affordable Housing Overlay Zoning can be applied anywhere, on any lot, if at least 70% of the units are priced to be affordable to a household at or below 60% of median income. If 70% of units are affordable, then the structure can be up to 2 stories taller than with the underlying zoning. In addition, any number of units can be built, so long as yard and setback requirements are met. One additional change is that the parking requirement would be a minimum of ½ space per unit. This reflects the actual parking usage at existing affordable housing owned by the Housing Corporation of Arlington. This proposal includes both rental and ownership units that are affordable.
A group of Arlington residents is proposing an amendment to our current zoning to include an Affordable Housing Overlay. This proposal will come before the Redevelopment Board for hearings in winter 2025 (probably during February or March), and then go to Town Meeting in spring 2025. There has already been one informational meeting on November 7 (slides and video), and there may be additional public informational meetings scheduled.
A municipality’s master plan is intended to set the vision and start the process of crafting the future of the municipality in regard to several elements, housing, history, culture, open space, transportation, finance, etc. Arlington began a very public discussion about these issues and the development of the Master Plan in 2012. In 2015, after thorough community wide discussion, the Master Plan was adopted by Town Meeting. This year, 2019, the focus is on passing Articles that will amend the current zoning bylaws in order to implement the housing vision that was approved in 2015.
Interview with Aaron Clausen, AICP; City of Beverly, Director, Planning and Community Development
Rather than express generalized worry about the “lack of affordable housing”, Peabody, Salem and Beverly have created an intermunicipal Memorandum of Mnderstanding (MOU) to very specifically define and target the problem and the population they want to address.
According to Aaron Clausen, “There is a fair amount of context that goes along with the MOU, but primarily the communities got together as sort of a coalition to survey and understand what was going on relative to homelessness. What came out of that is a recognition that there is not enough affordable housing generally, and particularly transitional housing, or more specifically permanent supportive housing.
“Salem and Beverly both have shelters, however the shelters were basically serving as permanent housing (and running out of space). That won’t help someone into a stable housing situation. Anyway, this was the agreement (attached MOU) and the good news is that it has resulted in affordable housing projects; one is done in Salem for individuals and Beverly has a 75 unit family housing project permitted and seeking funding that has a set aside for families either homeless or in danger of becoming homeless.
“There is also a redevelopment of a YMCA in downtown Beverly that will increase the number of Single Room Occupancy units. I wouldn’t say that the MOU got it done by itself but it helps demonstrate a regional approach. ”

Many issues are under discussion as a result of these proposed zoning Articles. Issues include: housing affordability, the diversity of housing and incomes in Arlington, environmental concerns and sustainability, tax burdens or tax savings potentially resulting from growth, the risk of postponing the decisions, and the image of Arlington as a community that values diversity and equitability. This one page “fact sheet” attempts to address many of these issues and concerns.
(DRAFT – 7/11/2019)
Overview

Arlington Planning Department officials report on options for the Town to mitigate the effects of housing demolitions and housing replacements in neighborhoods.
Evidence suggests that lack of appropriate regulatory policies have led to incidences of “mcmansions” and other issues that concern neighborhood residents. This study looks at the data, the policy and regulatory options for Arlington. It also looks at how comparable nearby communities have managed similar circumstances.
This 42 page report covers a great deal of data and analysis of homes by zoning district, gaps in the effectiveness of the current regulatory structure, affects on affordability in Arlington by zoning district, information on housing prices and sales, etc.
“Best practices” include descriptions of demolition delay, expansion of local historic districts, neighborhood conservation districts, design review standards and guidelines and possible revisions to the regulatory framework in Arlington. The report also includes interesting case examples of how comparable communities near Arlington handle these issues.
This report was presented to the Arlington Select Board on July 22.
Read the complete report and see the available data and tables.
State Representatives Dave Rogers (Arlington, Belmont and Cambridge) and Sean Garballey (Arlington, Medford) have sent a letter to Town Meeting Members backing the MBTA Communities Plan. They write:
We believe the plan in front of Town Meeting provides a meaningful framework to address the housing shortage in Arlington.
