2. Objectives
• Understand the roots of city and town
planning
• Understand the elements of a good
community
• Identify and understand the planning process
• Understand the nature of plan
implementation
• Engage in long range decision making
consistent with long term planning vision
3. “I know of no safe depository of the ultimate powers of
society but the people themselves, and if we think
them not enlighten to exercise their control with a
wholesome discretion, the remedy is not to take it
from them, but to inform their discretion by
education.”
Thomas Jefferson
5. “We ought to plan the ideal of our city with an
eye to four considerations. The first, as being
the most indispensable, is health.” — Aristotle
6. An Ancient Concern
“Thanks to you Germanicus, no
pillar is now with chained flagons,
nor does the grimy cook-shop
monopolize the public way. Barber,
tavern-keeper, cook and butcher
keep within their threshold. Now
Rome exists, which was so recently
one vast shop.”
Domitian, praising Roman City Planning Efforts, A.D.

8. 19th Century Roots in
Sanitation Reform
• Rapid Urbanization – 6% live in cities in 1800; 51% by 1920
•Miasma theory prevalent
•Council of Hygiene and Public Health in New York established in 1864
calls for elimination of noxious gas sources, dirty streets and overflowing
sewers
•U.S. Sanitation Commission established in 1861; Fredrick Law Olmstead
appointed Secretary during the civil war
•Urban landscape viewed as “crowded, dirty, polluted, smelly, noisy and
dangerous” and diseases originate and spread in poor neighborhoods
9. John Snow – 1854 - Broad Street, London
Established a connection of physical form and health
11. Urban Conditions at the Turn of the
Century
• Crowded tenements, 10 and 12 people to a
room
• Homes built 15 feet x 12 feet
• Cholera outbreaks
• No sewers

26. The Next 50 Years
• The United States will grow by 124 million people over the
next 50 years.
• We will need to build 40 to 50 million new housing units to
support that growth. What will the next generation of
development look like?
• The world’s population will grow by 2.3 billion people over the
next 50 years.

68. Three Small Town Development Eras
• Initial settlement towns – 1830’s to 1850’s,
first settlements, government centers
planned around town squares accessible to

town development prompted by railroad
development, either linear or gridded in form
70. • Automobile Towns – Post World War II
Development – 1920’s to present, linear in
form, develop around major auto routes

117. We are Downtown Brandon
We are Downtown Brandon, and we are real and genuine.
• In a region where communities are defined more by chain stores and highway development,
Brandon has remained the one traditional and authentic downtown in the metro area. With
our Town Square and historic architecture, quaint shops and active spaces, Downtown
Brandon has become a place to emulate and recreate.
• Downtown is the place that connects our people, and it the window to our community's
heart ands spirit. That spirit is seen on Red Friday's in our local shops, heard in children's’
voices playing at our downtown school, and tasted in the home town cooking in our
downtown restaurants. Most importantly, it is felt in the hospitality that our people are
known for, where Boy Scouts and beauty queens once greeted visitors on the Square with a
Coke and a smile.
• We strive to retain and enhance the character of our downtown. With an improved Town
Square, pedestrian enhancements, mixture of uses and active spaces, Downtown Brandon
will solidify its place as the heart and soul of our community and beyond. We are creating
new experiences in downtown, with opportunities for living, new cultural activities and
events, and more dining and shopping opportunities.
• This will only grow the spirit of our downtown and community, solidifying our place as the
singular quaint, small town experience surrounded by ordinary of the urban metro.
Downtown Brandon. Real Character. Genuine Charm

150. Subdivision Control
• Generally administrative in nature
• Usually involves the application of technical
engineering criteria to development
•As opposed to zoning, subdividing property is
considered “by-right “ if criteria are met
• Generally a heavy emphasis on infrastructure

165. Summary of Advantages and Disadvantages
Type of Code Advantages Disadvantages
Euclidean • Easy for City staff to implement and for the
public to interpret, if well organized.
• Familiar to professionals, staff, public officials,
and public.
• Flexibility for varied design within parameters
of use and dimensional standards.
• Lack of flexibility to address
different site characteristics and
surroundings.
• Only prevents the “worst” from
happening.
Performance Zoning • Flexibility to vary uses, density and intensity
of development and to address impacts.
• Impact approach may not
address site-specific conditions or
constraints.
• Difficult to implement - complex
calculations.
Form-based Codes • Graphics are more readily understood by public,
public officials, and professionals.
• "Prescriptive" approach outlines design
visually.
• Integrates the principles of mixed-use and
pedestrian orientation.
• Useful for developing new areas and some infill
sites.
• Not readily applicable to built-out
urban or suburban areas.
• Requires much up-front effort to
develop regulating plan and
design specifics.
• Can be highly subjective.
Incentive Zoning • Optional for developer.
• May provide public amenities with "win-win"
approach.
• Incentives may not be used, and
amenities not provided
• Win/win may be hard to achieve.

171. “And let's be careful how we regulate. Planners
from all across the U.S. have told me that they
are obliged to substantially revise form-based
codes adopted only five to 10 years ago. In one
case, the code had made 70 percent of the city
nonconforming and complicated simple home
additions, not to mention making new
development almost impossible. With due respect
to others, it's our obligation to respect the
strengths of various professions but our
responsibility to think comprehensively, anticipate
unintended effects, and deliver what it takes to
help a community grow both jobs and long-term
prosperity.”

185. A city’s built form is achieved through coding –
zoning, subdivision regulations, design codes,
building codes, preservation codes and
others…
And the administration of those codes over time
211. Consider the private and public costs and benefits of this place at 10 years and at 50
years?
212.

214. Guiding Site and Building Design
• Aligning both public and
private design interests
•Durable materials convey
characteristics of quality
and stability.
•The use of façade materials
native to the area, such
brick, stucco, and wood or
wood simulated siding
Discourage
Encourage
252. Why Programs Fail
• Most plans are poorly conceived and easily
challenged
• Disregard of the facts
• No defined goals or goals are ignored
• Poor administration by non-professionals
• Overly politicized, planning commissions
marginalized or non existent
253. Case Studies
What would you do?
• Background
• Issue is before the Planning Commission
• Implications
254. Rezoning Case Study # 2
Two applicants (Case 1 and Case 2) have requested rezoning of a small parcel to Office
to accommodate a Hair Salon. They will be heard at the same meeting.
Both application are vigorously opposed by the neighborhoods
Your planner has evaluated the applications and in a staff report has indicated the
following:
– The City Plan states that small scale traditional offices transitional offices in residential areas
may be appropriate principally for transitions and buffering between residential uses and
incompatible non-residential activities that cannot be reasonably mitigated through
landscaping, fencing, screening, or similar methods of buffering.
– The site should be suitable for the use based on its physical characteristics.
– The site should be of sufficient size shape to accommodate the proposed use and achieve an
acceptable design relationship with the adjoining uses.
– Access to the site should be from adjoining non-residential area or a side street that leads
directly into a non-residential area.
The Planning Commission has recommended approval of both case. How would
you vote?

upon that labor,
“See! This our mothers and fathers did for us.””
