AGENDA AND SESSION OBJECTIVES
• Context-Based Zoning and Placemaking Toolbox
• Common Principles and Best Practices
• Typical Elements of Context-Based Zoning
• Where Form-Based Codes and Other Tools are being
Applied in the Region
• Advantages & Challenges Going Forward


CONTEXT-BASED ZONING/PLACEMAKING TOOLS
Some Common Tools
• Form-Based Code (Used to Facilitate Other
Placemaking Tool)
• Traditional Neighborhood Development (TND)
• Transit Oriented Development (TOD)
• Strip Commercial Corridor Retrofit Planning
• Smart Parking Standards
• Complete Street Design
• Civic Spaces, Livable Streets, the Outdoor Room
• Tactical Urbanism


FORM-BASED CODE AND TND/ The Origins
Congress for the New Urbanism (CNU)
• Founded in 1993 and dedicated to promoting traditional mixed-use
neighborhood development and healthier living conditions.

Seaside Florida and Other Planned Development
• 1981 Seaside Development Code first modern day application of FBC.

Traditional Neighborhood Development (TND)
• Late 1980s/early 1990s several cities in SE US adopted FBC variants::
– Traditional Neighborhood Development (TND) ordinances.
Mashpee Commons, MA – Early TND
– Unified Development Ordinances (UDO) Cavendish Partnership/Cornish Assoc.

The SmartCode©
• Released by Duany Plater-Zyberk (DPZ) in 2003
• Model transect-based development code applied to all scales of planning
• SmartCode Version 9.2 - Open source with new modules

From “Greenfields” to Existing Built Environments
• Over the past 10 years, FBC has been applied city-wide as well as districts
targeted for revitalization and redevelopment.

FORM-BASED CODE BASICS/Common Principles
Context-Based Zoning
• Focus on existing or desired context and spacial patterns of
development and the surrounding environment (The Transect).

Public-Private Relationships
• Address the relationships between buildings and the “public
realm” (such as streets, open spaces, and civic buildings and
places).

Hierarchy of Purpose and Scale
• Buildings form, mass and scale
• Street types, purpose and treatments
• Active civic and open spaces

Physical Form vs. Land Use
• Focus on positioning of buildings and spaces rather than
separation of uses


FORM-BASED CODE BASICS/ The Transect
• System of ordered human habitats in a range from the most natural to the most urban.
• Defined by common physical characteristics of place, scale, density and intensity of land use.
• FBC is Transect Based Zoning integrating the elements of existing or intended habitats.

From the SmartCode©
Duany Plater-Zyberk


FORM-BASED CODE BASICS
Differences Between FBC and Conventional Zoning

• Integrated (Unified) Development Ordinance vs.
separate regulations (zoning, subdivision, site plan)
• Uses (Separation vs. Mix of Uses)
• Dimensional Standards (Simple numerical vs.
calibrated to shape public and private relationships.
• Building Placement, Orientation and Frontages
• Street Design Standards (to fit the context)
• Parking Standards (for shared uses)
• Civic and Open Space Standards (for active use)
• Design Standards vs. Guidelines TND vs Conventional Development
Example - Pittsford, NY


FORM-BASED CODE CALIBRATION
Process of Creating Context-Based Zoning
Evaluate Existing/Desirable Development Patterns
• Key dimensional, design and use characteristics of
existing/desirable development patterns
• Parking demand, distribution and occupancy trends
• Existing street “livability” characteristics
• Potential integration of desired civic and open space
• Identify performance standards for desired uses and street
activities

Define and Translate Community Vision
• Visual (Image) Preference Surveys
• Public Visioning, Scenario Building, and Design Charrettes
• Preparing a Strategic Conceptual Development Plan

Financial / Market Analysis
Sandy Sorlien-Smart Code Specialist.
New Commons- Community Outreach
Asked by Town to help preserve the
character, scale, walkability, and affordability
of the Village through charrette, FBC, and
Design Guidelines
Restore and protect the character of the
village.


Step 1: Establish Community Vision – Online Surveys

“walking to shops and restaurants and keeping East Ferry waterfront
accessible“

“don’t want to loose the small town character”

“Affordable housing for those whose families were born here.”

“That it is an island with open space, active farms and easy access to water”


Step 1: Establish Community Vision –
Dotting Exercises / Visual Preference survey


Community Preference came down to choice between this:


And This:


Demonstrated to community that development will come and is
already happening. (Inventoried current development proposals)

Can’t avoid development altogether.

Question is what type and form?


Much more potential for development than they realized
Used simple, rapid visualization techniques.


Showed that despite a single “village commercial” zone,
character of Narragansett Ave varied greatly from one end to
the other.


“East Ferry” characterized by 2 to 3
stories, with retail frontage on the 1st
floor


West end of Narragansett distinctly
more residential and loose. No retail
frontage.


“Four Corners” area much more auto-
scaled. “Working” retail.


Observed and measured existing conditions. Presented this back to
the community to better understand what they wanted to preserve.



• Predominant 2-1/2 story form

• Primarily retail or office at first floor

• Second and third floor more residential in character

• Third floor primarily in dormers



• Lot parking at side or rear

• Variety of frontage
• Limited front setback


Repeated the exercise for each distinct area of the village.
Made explicit what community understood intuitively.


West end of Narragansett has a different pattern from East end

• Predominantly 2 – 2-1/2 story form
• Residential character at first floor.
•Looser spacing, hedging instead of fencing, etc.
•Third floor primarily in dormers


West end of Narragansett has a different pattern from East end
• Driveways predominantly
at front or side
• Deeper front setbacks
• Still maintains strong street
edge


“Four Corners” exhibits a post war, auto-centric pattern.


“Four Corners” exhibits a post war, auto-centric pattern.
•Very deep setbacks.
•Parking in front
•Contemporary architectural styles


STEP 2: Demonstrated how the current ordinance does not do enough to
protect what they have or ensure more of it.


Showed that Village was vulnerable to development along
patterns of stuff they said they didn’t like

Present Conditions


Showed that Village was vulnerable to development along
patterns of stuff they said they didn’t like

What if Hurricane of
‘38 struck again??


CURRENT ZONING ALLOWS (MANDATES!) VERY DIFFERENT
KINDS OF DEVELOPMENT

Residents were shocked!


For key sites demonstrated “risk” posed by current ordinance and
alternative vision which could be encouraged by FBC


Residents very anxious about future of 1 acre lot, zoned commercial, in
residentially scaled end of Narrgansett Ave


Gave specific design proposals to illustrate importance of “form” as
opposed to lot coverage, use, or setback alone.


Nothing in ordinance to prevent Self Storage units, for example.


With proper form and placement commercial could be fine


Showed how without “down zoning” currently permitted intensity of use
could be accommodated in sympathy with the neighborhood.


Showed how, without “down zoning,” currently permitted intensity of use
could be accommodated in sympathy with the neighborhood.


Showed how “most hated site” could be repaired over time by incremental
development guided by FBC


Different development scenarios explored to help community – and owner
– understand how it might build-out.


Different development scenarios explored to help community – and owner
– understand how it might build-out over time.


Very simple controls on form could transform this:


To this:


Had immediate effect. Town and local developer teamed up to flesh out a
master plan.


Advocated for different “visions” for different “zones”. One size does NOT
fit all. Not all of village, can or should be residentially scaled.


Needed a “working retail” location convenient to autos, but deferring to
pedestrians.


Proposal leveraged planned improvements (new post office, funded
streetscape work, branch bank relocation) to create “real” shopping.


Goals discovered by study, design, and community outreach translated
back into regulating plan.


A Single Commercial Downtown Zone redrawn as 3 “T-zones” reflecting
differing visions for each.


Civic buildings, civic spaces, recommended retail frontage, view
corridors terminated vistas, street and walkway types all identified.


Model “SmartCode” calibrated for each T-Zone.


Ordinance changes supplemented with Design Guidelines.


“Soft Ordinance” Serves to guide the willing (95%) without forcing the
unwilling (5%). “Objective” - wont change with changing personnel.


Adoption within Comprehensive Plan gives it legal standing… of a sort.
Since most projects require relief, it becomes effective bargaining chip.


Form Based diagrams can supplement conventional ordinance to great effect.

Somerville, MA
• 4.5 sq miles

• 70,000+ population

• North of Cambridge, MA

• Densest city in New England

• A city of squares

. . . And the community is preparing for it . . .

The Code:
Three Challenges of the SZO

The Code:
1. Code structure is unworkable:
• Language is unreadable and subject to wide interpretation
• Attempts to describe physical form through words
• Answers to basic questions are scattered across sections
• Additional districts are cobbled onto code structure

The Code:

2. RA/RB Districts don’t provide a predictable outcome:
• Nonconformity is used as a proxy for design review
• Large by-right lots have no design review
• Wide ranges of possible outcomes by special permit
• Larger mixed-income projects require much negotiation

The Code:


3. Transit station zoning is misapplied on the map
• Innerbelt and Brickbottom are in old industrial zones
• Gilman, Magoun and Ball Square have limited options
• Porter and Davis have select areas that are underzoned
• New Union Square and Broadway zoning need clarity

The Lesson
of
Organization

The Somerville Zoning Ordinance (SZO):

1. Built on a conventional code from 1925

2. Additions have been cobbled on for many years

3. Definitions in text / regulation in definitions
(lacks performance standards for specific uses)

4. Many cross-reference sections

5. 90+% of lots nonconforming – nonconformity used for design review

6. New additions for Assembly Square, Union Square and Broadway

Like many local codes: The results are good – but the process is not

Conventional Zoning

“To say (conventional zoning) is cookie-
cutter is unfair to the cookie industry . . .

. . . there is actually some thought to
alternative forms of cookies”

• “designed in a manner that is compatible with the
existing natural features of the site and is
compatible with the characteristics of the built and
unbuilt surrounding areas.”

• “consistent with the general purpose of this

Lots in Two Districts
Land in a more restrictive zoning district
may supply space for a use permitted in a
less restricted zoning district if the use of
the land in the more restrictive district
satisfies space and passive use
requirements (such as setbacks,
landscaping or parking) that are not
prohibited in the more restrictive district.

Lots Abutting Other Districts

Where a lot in a business or industrial
district abuts a lot or district line in a RA,
RB, or RC district, no building in the
business or industrial district shall be
erected closer to the residential line than
one-third (1/3) the height of the said
building, but not less than fifteen (15) feet.

The Extended Charrette: Lowell

Standard Charrette Phases:
• Research, Education and Preparation
• Charrette
• Plan Implementation


NCI Charrette
• At least four consecutive days
• Allowing for at least three design feedback loops
• Open process including all interested parties
• Creates a feasible product with minimal work


• Lowell Charrette
• Same preparation and
implementation steps
• Four days of design and public
participation spread over four
months
• Feedback loops


• Lowell Charrette
• Months of outreach before first session
• Early listening sessions
• Cross functional collaborative team
• Feasible outcome that is embedded in the code
• Design as the basis for the shared vision
• No opposition to FBC and universal political support for
the plan

Benefits of the Somerville by Design Code

• Establishes Somerville as ‘open for development’ in transit
areas

• Conserves the character of core residential neighborhoods

• Continues our tradition of using best practices in municipal
government

• Implements over 100 recommendations of the SomerVision
plan in a regulatory structure that will produce long-term
impacts

• Provides predictable high quality outcomes

A new solution to the SZO?

Structure of the SZO: The SZO as a FBC:

FORM-BASED CODE APPLICATIONS
The Legal Landscape in New England

Matthew Lawlor, CNU-A

Robinson & Cole LLP



• Legal authorization of FBCs has not been seriously challenged
• REPEAT: Legal authorization of FBCs has not been seriously challenged
• Multiple authors (Emerson, Sitkowski, Slone) have confirmed this reading
• Enabling statutes are not the problem
• Still need to confirm jurisdiction’s case law not a bar…
• …And beware of issues of application as follows



• First things first
• Plan and vision before drafting the FBC
• Otherwise, the FBC has no vision to which it is coding
• The overall goal: Plan, vision, and code to the maximum extent possible
• Seek diminishing discretion: Plan for the code, not each individual project.



• Specific implementation issues:

– Appreciate the potential for plan-based inverse condemnation (if you lay down too
many streets you don’t intend to take) [Tri-Town Example]
– Watch for regulatory schemes outside of zoning (state-mandated multi-
family/commercial site plan review, for example) [Dover Example]
– Sticking within the statutory scheme for zoning and building code review and permit
issuance (create a new scheme at your own peril) [Lowell Example]


Advantages
• Stronger Connections Between
Development Plans, The Community’s Vision
and Land Use Regulations
• Can be Calibrated to Existing Desirable
Conditions
• Predictable Physical Outcomes of
Development
• Encourages Diversity
• Higher Quality Development
• Effectively Replaces Design Guidelines
• Creates a Supportive Relationships between
Private Development and The Public Realm
