Traditional Neighborhood Development (TND)

In Brief: TND, also known as "new urbanism", "neo-traditional" or village-style development, includes a variety of housing types, a mix of land uses, an active center, a walkable design, and often a transit option within a compact neighborhood scale area either as infill in an existing developed area or as a district scale project.
The Problem
Traditional Neighborhood Development seeks to remedy the most pressing problems associated with recent suburban expansion - low-density, auto-oriented development, single-use developments lacking in context and distinction as a unique community.

Automoblie dependance results from the segmentation of residential, commercial, and industrial uses as is often required in modern zoning. This design practice results in the loss of community vitality and makes neighborhoods unwelcoming to pedestrians and bicyclists. It also increases traffic. However zoning utilizing TND development that mixes uses in a compact area and forms can acheive a high quality neighborhood.

Commercial "Big Box" sprawl and residential sprawl.
The segregation of uses has also led to isolated zones for commercial, residential and institutional areas, which are only linked by auto and are thus failing to create walk-able, pedestrian friendly neighborhoods. While conventional zoning closely regulates a variety of aspects related to use, parking, buffers etc., it does not regulate the aspects that help in enhancing the character of buildings, streets, and open spaces, which together form a neighborhood. How can development be planned in a way that not only encourages a mix of uses in a compact area but also provides a way to shape the form of a cohesive neighborhood?
Through form-based zoning and other standard bylaws, zoning can be an extremely effective tool that communities can use to implement TND. TND can guide new development patterns that are civic-oriented, pedestrian-friendly, economically vibrant, environmentally sustainable, and evoke a unique sense of place. However, certain principles that have been applied to New Urbanist developments across the United States - such as Kentlands, Maryland; Celebration and Seaside, Florida; and Stapleton, Colorado - will not meet the needs of most communities in Massachusetts without modification. New England communities have a long history that has already defined the form and fabric of neighborhoods in important ways. This section of the Toolkit explains how Traditional Neighborhood Design standards can be adjusted to fit within the New England context and work in diverse communities throughout Massachusetts.

Introduction to Traditional Neighborhood Development

TND planning graphic.Traditional Neighborhood Development helps to create vibrant mixed-use neighborhoods with higher densities and a range of complementary uses. TND is characterized by compact, pedestrian-oriented developments that provide a variety of uses, diverse housing types, and are anchored by a central public space and civic activity. TND is based on the principle that neighborhoods should be walkable, affordable, accessible, distinctive, and in Massachusetts, true to the significant historic context of each community.

The following are commonly found in TND:

  • Parks, schools, civic buildings, and commercial establishments located within walking distance of homes
  • Residences with narrow front setbacks, front porches, and detached rear garages or alley-loaded parking
  • Network of streets and paths suitable for pedestrians, bicyclists, and vehicles
  • Narrower streets with crosswalks, streetscaping, and other traffic-calming measures
  • In-scale development that fits the local context
  • Buildings oriented to the street with parking behind


TND can be used to revitalize existing town centers and neighborhoods or build new ones at transit nodes and in other locations. Current and future public transit stops are important places to consider during the planning stages to maximize access to alternatives forms of transport (see Transit Oriented Development). However, TND must be distinguished from Transit Oriented Development - TND need not focus as close on transportation areas and parking as components of urban design.

TND will not be appropriate for all neighborhoods in all contexts, though. Many of the design criteria and standards of TND can be applied to other development projects. However, not every neighborhood is suitable for the density required for a mixed-use TND development to succeed. While auto-oriented strip malls and large-lot developments are fundamentally incompatible with TND in their present condition. These types of locations represent prime opportunities for conversion to TND over the long term. Communities need to carefully consider local real estate markets in order identify the most viable locations for TND development.

Success

Mashpee CommonsWhile TND is defined by certain development patterns, TND's success is marked by its ability to blend into and enhance the unique spaces that it inhabits. This criteria of success becomes especially important in New England, where towns and cities have a strong sense of place. TND in New England must be customized to each place so that the rich character of towns and cities is strengthened, not fabricated, by Traditional Neighborhood Development.

Traditional Neighborhood Development in Massachusetts

What makes a traditional New England village?

As the birthplace of the nation, the New England village is a physical and historic representation of community.  Anchored by a village center, the New England village is walkable, provides a strong mix of uses, conveys a distinct sense of place, provides housing for residents at all income levels, and is accessible. Classic New England villages have retained their strong identities through time, resisting change and the impulse to completely replace old with new.  Each village’s character is informed by local history and geography and coastal, riverfront, highlands, and farming communities each convey a very different sense of place. 

More than historic relics, successful New England villages remain living, active places. The modern village integrates contemporary uses into the historic fabric of each community, with new residential and commercial developments built around the historic village district. The modern New England village is oriented to a quality of life associated with current conveniences, integrated with historic buildings, roads and open spaces, and designed for the unique character of the location.  As a result, the modern New England village can be any number of configurations. The richness of Massachusetts ’s landscape, history, and local culture provide a variety of ways for TND to be implemented in this state. 

What are the basic TND guidelines?

Generally, TND is neighborhood in scale, 10 to 15 acres in area based on the geometry of a 1/4–mile maximum walking distance. Open space is typically 10% to 20% of the area, and about 70%-80% of the area is devoted to residential blocks, with the remainder (approximately 10%) as mixed use with a focus on viable commercial space and civic functions. TND requires dense (e.g. quarter-acre and smaller lots) residential blocks in order to create an internally-oriented neighborhood with enough people to help support the commercial and civic functions.

However, a larger market area is often necessary to support businesses and provide outside job opportunities for residents. Consequently, access is provided in multiple ways to provide that choice and opportunity. The regional transportation systems; trains, buses, and highways, are also connected to facilitate mobility.

Beyond these basic requirements, TND principles can be modified to fit unique circumstances in each community.

How and where is TND working in Massachusetts ?

Here are some ways that TND is actually working in Massachusetts at very different scales and situations:

Large scale / Urban - Urban areas are usually characterized by a high degree of existing build-out, which makes it difficult to assemble raw land on which to build a new full-scale traditional neighborhood. However, some districts within the city, such as disinvested downtown neighborhoods and neighborhood surrounding academic institutions, can offer promising potential for TND. TND principles are also especially applicable to the development and redevelopment of large-scale housing projects (public and market-rate), mixed-use complexes, and failed shopping malls. Within suburban areas, large-scale vacancies – often caused by military base, airport, or strip mall closures – present great opportunities in which to introduce a Traditional Neighborhood Development. The greatest potential for TND in Massachusetts is in the repair of existing urban fabric. Infill and redevelopment of obsolete buildings present tremendous TND possibility

Examples of Large-scale / Urban Projects – In Massachusetts , many large-scale projects have been able combine TND and land use principles into economically successful developments. Marina Bay in Quincy has an active commercial boardwalk and provides housing for residents at all age and income levels, from seniors to single families.  Hingham Shipyard in Hingham will convert 130 underutilized acres of property into a new mixed-use development project with nearby MBTA access. Redevelopment of the South Weymouth Naval Air Station in Weymouth will create multiple new neighborhoods, provide new jobs, and increase connectivity to commuter rail and the regional highway system. Assembly Square in Somerville connects urban-scale commercial and residential uses to transit, highways, and riverfront open space.  The Fan Pier Plan in Boston is a nine-block, mixed-use, waterfront redevelopment in a dense urban setting.

Mid-scale / Suburban – TND is an alternative to and a means of combating the problems associated with suburban development.  The suburbs are growing at a significantly faster pace than urban and rural areas, and this growth offers ample opportunity in which to apply TND. Important elements of local character or history in established residential or commercial areas should be incorporated into the TND to distinguish the location. 

Examples of Mid-scale / Suburban Projects – Medium-scale projects that may have a more limited mix of uses can still fulfill many of the principles of TND.  Woodbourne in Boston , an historic district built between 1911 and 1945, has housing and civic uses that are closely oriented to the residents and create a sense of neighborhood. Although now located within a major metropolitan city, Woodbourne still provides the unique sense of place for its residents. Mashpee Commons in Mashpee developed a vibrant commercial center with a traditional main street on the site of a vacant shopping mall. Surrounded by significant residential and resort development, Mashpee Commons has established an updated community commercial center of regional signifigance.

Small-scale / Rural – Traditional suburban development patterns have migrated into rural areas and TND is as applicable in smaller towns as it is in suburban cities.  Development on greenfield sites located in rural areas can be guided by TND principles in order to minimize environmental impacts associated with new development. A more apt use of TND may be to re-establish or expand existing village centers as centers of community life.

Examples of Small-scale / Rural Projects - Village Commons in South Hadley is one of the smallest projects that effectively uses design to integrate a new commercial center into the fabric and life of a college neighborhood. At about 80,000 square feet of commercial space, it works in similar function as Mashpee Commons does in supporting the surrounding college and community residents. Dennis Village Center in Cape Cod utilizes the traditional Cape Cod building design in the existing village center and has generated reinvestment. By utilizing graphics to help residents visualize the changes, the town was successful in rezoning the area to meet the goals of TND, on a local scale.

Project Sites – TND’s are usually about 10 to 15 acres in size when done on a town scale. However, the incorporation of existing residential or commercial blocks into a TND means a project does not require a wholly undeveloped site, and the projects do not have to be completed by a single entity. The key is designing the new elements to fully connect with the old. Valuable TND projects may be infill development projects within existing downtown or neighborhood areas.

Comprehensive Design Standards – TND neighborhoods are carefully designed to function in ways that provide a high quality of life. It is therefore important that local governments have the authority to regulate many design aspects and aesthetics. TND often involves local regulations govering a wide range of urban design choices – from façade and paving materials, to geometry and dimensions, to specific organization of uses. These should be specific to the community based on local design principles. The local history should be an important consideration in the design of TND projects as the resulting community–oriented design and complementary architecture will then provide for a strong sense of place.

Diversity in Housing - The variety of types of housing units typical of TND gives people and households at all stages of life housing alternatives suited to their needs, thus providing stability to a community. The proper density of housing (typically very high) will also support the commercial and civic functions at the TND.

Accessibility and Mobility – TND’s require local connectivity and access to all areas, but cannot stand alone. Consequently, along with bicycling, walking, and vehicle access, TND’s should provide additional access with choices including public transit. Trains and buses provide transit options, but must be considered along with regional highway access.

Zoning Creation Process for TND

Because of the complexity of these projects, the recommendation is to follow three steps in the creation of the TND zoning:

  1. Establish the design principles from the criteria included in this module, and essentially create a first draft of the zoning code;
  2. Complete a charrette process where those design principles are used to develop potential projects and then review the results. This will help people to understand the potential outcome from the use of these design principles; and then,
  3. Complete the drafting of the zoning bylaws.

The recommended first step in crafting TND regulations is to define the community's approach through the adoption of principles and objectives for TND. The TND principles and objectives of particular importance are:

  • Sustainability
  • Compact Development
  • Mix of Uses
  • Accessibility and Transportation
  • Cultural and Environmental Context

More on these design principles can be found within the Model Bylaw.

The purpose of a charrette is to solve a design-related problem facing a community. The public is invited to attend and participate and the charrette process is best if facilitated by trained individuals.

The typical agenda of the charrette is to first educate participants on the process, and then incorporate their contributions in order to verify decisions. A charrette usually lasts a few hours or even several days and culminates with the presentation of a final plan, which is a compilation of the best ideas offered during the charrette. The results of this process should then inform the drafting of the bylaws.

The TND zoning bylaws may include three different types of regulatory standards to accomplish the design principles; Performance Standards, Design Guidelines, and Form-based standards.

Unlike prescriptive standards, Performance Standards present a specific statement of intent and the development must show how it meets that standard. These are typically used for environmental and management and mitigation of land use impacts. Design Guidelines can specify allowable architectural styles, building materials, colors, building heights, landscaping, and can also require diversity in the styles, including architectural and landscape design. Form-based zoning refers to the idea of identifying the form of the built environment based on the context of the physical surroundings or district, but not strictly regulating the allowed uses, which may otherwise be defined in the underlying zoning.

Form-based zoning creates the physical context, Design Guidelines allow for more granular control of the built elements, and Performance Standards ensure the best management of the land and built environment. However, in many cases traditional dimensional and prescriptive standards may be used in place of these newer types of regulations, as local preference requires.

TND advances several of the Patrick Administration's Sustainable Development Principles, including:

Concentrate Development and Mix Uses: TND increases development densities within the village or town center to promote the ability to work, shop, and live in one neighborhood and provides economical opportunities for mixed use redevelopment of existing properties. In addition, TND is compact, encourages reuse and rehabilitation of existing infrastructure, conserves land, integrates uses, and fosters a sense of place. It creates walkable districts mixing commercial, civic, cultural, educational and recreational activities with open space and housing for diverse communities.

Protect Land and Ecosystems: TND protects land in two ways; first by providing development opportunities that do not impact "greenfields" and second by providing economical redevelopment that allows for the correction of existing site deficiencies. TND increases the quantity, quality, and accessibility of open space, expands land and water conservation and promotes development that respects and enhances the region's natural resources.

Use Natural Resources Wisely: TND encourages efficient use of land and promotes buildings and infrastructure that uses land, energy, water and materials efficiently.

Expand Housing Opportunities: By linking commercial development in the district to the provision of rental and affordable housing opportunities, TND supports the construction and rehabilitation of housing to meet the needs of people of all abilities, income levels and household types. TND coordinates the provision of housing with the location of jobs, transit and services and fosters the development of housing, particularly multifamily, that is compatible with a community's character and vision.

Provide Transportation Choice: By improving pedestrian facilities in the village and increasing the viability of transit by increasing residential density, TND maintains and expands transportation options, in all communities, including land- and water-based public transit, bicycling, and walking.

Increase Job and Business Opportunities: By providing for increased intensities of development and encouraging the creation of new jobs in the village center, TND attracts businesses with good jobs to locations near housing, infrastructure, water, and transportation options and supports the growth of new and existing local businesses. TND strengthens the growth of local businesses, in addition to supporting economic development in industry clusters, which are consistent with regional and local character

Plan Regionally: By implementing recommendations found in the Town's Comprehensive Plan and the Regional Policy Plan, TND supports the development and implementation of local and regional plans that have broad public support and are consistent with sustainability principles. It also fosters development projects; land and water conservation, transportation and housing that have a regional or multi-community benefit.

Benefits to Community

By promoting development in existing neighborhoods and village areas using TND, municipalities can take advantage of existing infrastructure instead of building new. Within greenfield projects, the very compact nature of a TND also reduces infrastructure costs.

Mixed-use projects reduce the need for total vehicle trips. In addition, residents within these projects are able to reduce households expenses associated with car trips. The normal level of constant activity associated with mixed-use projects also improves the sense of security.

By adopting design guidelines or form-based codes as a part of a TND overlay zone instead of the conventional zoning standards, municipalities can more closely regulate the design and character of development. The result can be better utilization of land area, improved tax benefits, and lower capital costs. When correctly designed, the costs to the developers are returned with higher value projects.

By specifying design standards to the developers who are financing the TND's, municipalities can use the project investment to create safer streets and public open spaces. By capitalizing on the strength of the local housing market and broader economic and market trends which are favoring TND, municipalities can build on the demand for New Urbanist, village style development.

By improving the potential for development in the existing village and town centers and adjoining sites, not only can municipalities capitalize on the existing infrastructure, they can also benefit from the tax returns to the community as a whole form a reinvigorated commercial center.
