Thoughts on Newton Village Center Zoning
Contents
Introduction
This web site is intended to examine Village Center Zoning in general and also to focus on special issues related to the VC1 districts in particular.
I will use quotations from city documents and snapshots of data tables. Along the way, I will raise issues, ask questions, and make suggestions.
My impression is that the proposed zoning ordinance will lead to a dramatic increase in the residential density in the neighborhoods that already have residential buildings and that have been placed into VC districts.
Is this impression correct?
If so: Why is such a dramatic increase in the residential density being proposed?
For access to copies of the city documents and to details of the data studies, go to:
The District Purpose of the Village Center 1 (VC1) District
The first draft of the Village Center Overlay District (VCOD) Ordinance states that the purpose of the VC1 district is:
Village Center 1 (VC1). The VC1 District facilitates small to medium scale multi-family buildings given its proximity to amenities, mixture of uses, and transit options found in Newton’s village centers. This district acts as a transition between the mixed-use cores of village centers and the surrounding residential neighborhoods.
The buildings that currently have been placed in the VC1 districts according to the draft maps are close to 100% residential. This begs a question:
Why do existing residential buildings have to become “transformed” to act as a transition to existing adjacent residential buildings in the “surrounding neighborhood”?
If the question is simply one of modestly increasing the residential density in the area encompassed by certain buildings then this may be accomplished by an adjustment to an existing MR zone or by the creation of a new MR zone if needed.
This is not merely a semantic issue.
If the buildings in question are zoned with a residential designation then:
- These residential buildings will be entitled to greater setbacks from the buildings in adjacent VC2 or VC3 zones.
- These residential buildings will be required to have 15 foot side setbacks from one another rather than the more limited 10 foot side setbacks in the VC1 regulations.
Existing residential buildings should not lose their residential status simply by being placed on zoning maps.
Study of the Village Center Zoned Area based on the 1.0 Zoning Maps
Conclusions:
- There are large disparities between the zoned area impact across the 12 villages.
- Newton Corner and Newtonville are the most impacted with 2.6 and 2.2 million square feet zoned.
- West Newton and Newton Centre are the next most impacted with over 1.7 million square feet zoned.
- All other villages have less than 1 million square feet zoned.
- The total of all zoned area is only 2.72% of the area of Newton.
- To me, it seems unlikely that this small an area will meet the desired housing needs of Newton. Therefore additional zoning will need to be done outside of village centers.
Data Analysis of Existing Residential Buildings in VC Zones
Conclusions:
- There are large disparities between the residential buildings impacted across the 12 villages.
- Newtonville and Newton Corner are most impacted with 110 and 85 residential buildings rezoned.
- There are 4 villages with between 28 and 39 residential buildings rezoned.
- The remaining 6 villages have 16 or fewer residential buildings rezoned.
- Overall, there are 401 residential buildings rezoned, 71 apartments and 330 homes.
- In VC1 districts, there are 263 residential buildings rezoned, 26 apartments and 237 homes.
- Although transit orientation is often spoken of in relation to village centers:
-
- Only 3 of the 8 Green Line stops in Newton appear in the list of village centers.
- The commuter rail stops are listed but we know that commuter rail service is limited.
- Newton Corner has good bus service to Boston (57, 501, 504) but not to the rest of Newton.
- The 553, 554, 556, 558 bus lines no longer go express to Boston but rather terminate at Newton Corner.
- The bus lines that pass through Newton (other than the 57 bus) have limited service.
- 2 of the 12 villages have no transit whatsoever.
- Given that 9 of the 12 villages have poor transportation or no transportation at all, it would seem that transit orientation should be less of the conversation.
Residential Density in VC1 Districts
The meeting of Zoning and Planning (ZAP) committee on December 12 2022 was quite important because it provided a detailed look at the residential density enabled by version 1.0 of the village center zoning ordinance. Since the details cannot be included here, I give the references.
Version 1.0 of the village center zoning ordinance:
Slides from the ZAP meeting on December 12 2022:
Data analysis of the slides from the ZAP meeting on December 12 2022:
The West Newton Armory Affordable Housing Project {for comparisons}
The slides from the ZAP meeting on December 12 2022 have:
- 3 main studies of residential density in a VC1 setting
- a study of the smallest lot that may contain a 4000 square foot (SF) building
- a reference to one home in Newton Corner (11 Washington St) that exemplifies quality adaptive reuse
The 3 main studies of residential density in a VC1 setting are:
- Slides 6-7: Lot Size Greater than 30000 SF {based on 714-724 Beacon St}
- Slides 8-9: Combining Two Lots {based on 1359 Centre St and 1365 Centre St}
- Slides 10-11: Small Lot {based on 1359 Centre St}
Here are the number of units in each example based on whether there will be underground parking or surface parking:
Lot Size Greater than 30000 SF
- Lot Size: 31221
- Number of Units:
-
- Underground parking: 31
- Surface parking: 22
Lot Combining Two Lots
- Lot Size: 17710
- Number of Units:
-
- Underground parking: 21
- Surface parking: 15
Small Lot
- Lot Size: 6500
- Number of Units:
-
- Underground parking: 8
- Surface parking: 6
I was astonished at the intensity of the residential density enabled by the proposed VC1 zoning rules, both when listening at the ZAP meeting and later when examining the data in depth.
To wrap my head around the situation, I decided to consider my own house and its lot as an example. I realized that 6500 SF is approximately the size of my lot in Newton Corner and of many other lots on my block. The buildings on my block currently have 1-3 units. Therefore:
The proposed VC1 zoning rules would permit doubling the residential density on my block or even multiplying that density by 2.67 {8/3}.
Another, less anecdotal, way to look at the residential density question is to extrapolate the 6500 SF density data to estimate the number of units per acre. One acre = 43560 SF. The ratio 43560/6500 is 6.7. Therefore, we may estimate the number of units per acre using small lots of size approximately 6500 SF by multiplying the above counts by 6.7 and then rounding down.
One acre via using multiple small lots
- Number of Units:
-
- Underground parking: 53
- Surface parking: 40
Either of these “number of units per acre” values are far in excess of the mandate of the MBTA communities law that requires only a minimum of 15 units per acre.
A third way to approach the residential density question is to look at the West Newton Armory Affordable Housing Project to seek comparisons. It is best to look at a single floor in the plans and to use an upper floor since there are no complications of the building lobby.
West Newton Armory data for a single upper floor:
- Floor footprint: 12360
- Units per floor: 11
- Unit makeup:
-
- 4 units with 1 bedroom of sizes from 608 SF to 720 SF
- 5 units with 2 bedrooms of sizes from 850 SF to 888 SF
- 2 units with 3 bedrooms of sizes from 990 SF to 1018 SF
- Total area of all units: 8978 SF
- Average unit size area: 816 SF
- Percentage of total floor area that is useful as apartment floor area: 8978/12360 or 73%.
This data is relevant since it shows a plan with a distribution of room sizes and shows the net areas of the rooms rather than the gross areas. This data also shows that the net area of the apartments is smaller than the gross floor plan area. In the West Newton Armory case, the ratio is 73%. I believe that in other cases 80% would be the most that might be achieved.
One key constant in the 3 main studies of residential density is the gross area per unit which is set at 1000 SF. The corresponding net area would be 800 SF or less. Given the apartment sizes for the West Newton Armory, this seems to be a skimpy allowance for the apartment sizes in the VC1 districts.
The second study in the December 12 ZAP slides is a study of the smallest lot that may contain a 4000 square foot (SF) building designed as 40 feet by 100 feet. The building is estimated to have 10 units by the same methods as in the earlier examples. The interesting information is:
- Lot size: 13050 SF
- Building footprint: 4000 SF
- Total space for parking: 6040 SF
-
- Rear parking for 10 cars: 3840 SF
- 20 foot wide driveway: 2200 SF
- Usable open space: 3010 SF
- Usable open space / Lot size: 23%
The total space for parking is 1.5 times the building footprint. This shows the impact of parking on development.
Finally, there is a slide entitled "Residential Building Comparison for VC1" that shows photos of three buildings. The one that interests me is a home in my neighborhood: 11 Washington St. This home is described as: Multi-Family Residential: 6-unit converted Victorian, with footprint 3831 SF.
This is a charming building on the north side of Washington St whose lot abuts the Newton Brighton line. It has indeed been subdivided into 6 condos with one 4 RM 1 BR, three 4 RM 2 BR, and two 5 RM 2 BR units. The unit sizes range from 1003 SF to 1541 SF. The total unit area of all condos is 7896 SF.
What is not mentioned on the ZAP slide is that the building has a front setback of 64 feet and that it is the sole building on a very large lot of size 60002 SF. The 11 Washington St lot is not in a VC1 district but if it were then it would be subject to having a large number of buildings built on the lot. By doubling the numbers in the 30000 SF study above, we might estimate the number of units as anywhere from 40 to 60 total units. Furthermore, the current 11 Washington St structure might be unlikely to survive such development.
Some key questions are:
Have I described the current residential density policy for VC1 accurately?
If so, on reflection, is the policy of ZAP and the Planning Dept to strive for this intensity of residential density in VC1 districts?
If so, what is the justification in terms of benefit to the residents of the village centers?
Reuse and Revitalization of Existing Buildings
There is little in the draft zoning ordinance about reuse and revitalization of existing buildings.
Section 7 entitled Adaptive Reuse has the following paragraph:
The reuse and revitalization of existing buildings, particularly large homes, within the VCOD tiers will benefit the general health and welfare of the Newton community by fulfilling stated goals on housing, transportation, sustainability, and historic preservation.
This paragraph is simply followed by a section marked “[reserved]” that is presumably to be filled in later.
As it stands, these words represent a “wish list” that has no legal force. It is up to a developer to decide to renovate or tear down an existing building.
In my opinion, the intense increase in residential density allowed by the current version of the zoning ordinance and the ability of developers to do what they wish “by right’ is a financial and legal combination of forces that incentivizes tear downs. To state it bluntly:
Residential buildings in the VC zones will be designated for demolition.
Suggestions
I believe that the cleanest solution to the problems of the current zoning starts with replacing VC1 by an MR type zone that is explicitly residential. Let me call the zone MRX.
The huge advantage of this solution is that MRX may be used all over Newton and be introduced to well chosen areas on a gradual basis. This can lead to a graceful increase in density over time.
For the purposes of further discussion, let me use the term MRX {which may turn out to be VC1}.
Here are some ideas about how to handle MRX {or VC1}.
- MRX should be designed to permit significant but moderate increases in residential density as compared to the existing MR zones. The definition of “significant but moderate” should be a topic of discussion between the city and the community given the concerns with the current definitions.
- MRX will have the privileges of a “residential” zone vis-a-vis VC zones.
- MRX will not permit multi-use or commercial buildings.
- The next conditions are intended to secure more usable open space including rear open space.
- An MRX lot should have at least 10 feet of front setback.
- An MRX lot should have at least 15 feet for each side setback.
- One side setback may be used for a driveway and may be 20 feet in width.
- An MRX lot should have at least one side setback that is non-paved usable open space.
- An MRX lot should have at least 15 feet for a rear setback that is non-paved usable open space.
- If a change is made to a building or buildings on an MRX lot, the total number of housing units on the lot may not be reduced.
- In MRX, a developer may do the following by right subject to standard dimensional restrictions and subject to the constraint that the total number of housing units may not be reduced:
-
- Reconfigure the interior of an existing building.
- Add an addition to the rear of an existing building.
- Add an accessory dwelling unit (ADU).
- Add porches or decks.
- A proposed “tear down” in an MRX district should require a special permit.
- The special permit application should require:
-
- An explanation of why adaptive reuse is either not possible or not desirable.
- A discussion of the benefits of the new structure(s) to the city.
- A discussion of the benefits of the new structure(s) to the neighborhood.
- If tear downs are becoming common in an MRX neighborhood, the city must slow the process.
- I propose that if 50% of the structures in a neighborhood have already been torn down then there must be a 5 year gap between each subsequent tear down. This will maintain the core fabric of the neighborhood over time.
There are some issues that apply to both MRX {or VC1} and VC2, VC3 zones. These are the questions of what is a half story and how should the top story be treated if it is not a half story. The half story constraint that I propose is based on how half stories are handled in the December 12 ZAP slides. The constraint applies whether or not roof lines are sloped.
- The footprint of a top story is the footprint of the area within that story where the ceiling is at least 7 feet in height.
- A top story may be considered to be a half story provided that its footprint is no more than 2/3 of the footprint of the building.
- A top story that is not a half story should have a flat roof, should not have visible equipment on the flat roof, and should have setbacks of 10 feet on the front and sides above the roof of the story below.
Final Thoughts
My sense in early January 2023 is that the city is listening to concerns about the village center zoning maps and beginning to come to grips with what areas should be residential and what areas should be VC2 or VC3 as seen by the local communities.
The harder issues are that
guard rails are not in place that promote density in a significant but moderate fashion, that incentivize adaptive reuse of residential buildings, and that discourage tear downs. I have tried to put forth some ideas along these lines in the
Suggestions above.
It is clear from the small area of the village centers (2.72% of the city) that additional zoning to promote additional housing must be done in areas beyond the village centers. These areas will necessarily be residential. To do the additional zoning, you will need to invent something like the MRX zone that I propose. It would be wise to invent MRX now and then use it in chosen area across the city as well as in the village centers. Such a plan will work provided that MRX supports significant but moderate increases in density and promotes adaptive reuse. It will not work if people are frightened of the intensity of the proposed residential density.
