WHY CONTROL DESIGN?

ANYWHERE, USA
HERNDON, VA
You cant legislate good taste
4
ANYWHERE, USA The Old Lincoln Highway Western
Pennsylvania
Is it just to make places look better?
5
ANYWHERE, USA
PURCELLVILLE, VA
COMMERCIAL ZONING
ALSO COMMERCIAL ZONING
To protect property values investments in the
quality character of a place
6
ANYWHERE, USA
PORT WARWICK, VA
RESIDENTIAL ZONING
ALSO RESIDENTIAL ZONING
To ensure predictability in decision making and
outcomes expectation that places will grow and
develop as intended
7
ANYWHERE, USA
NEW TOWN, VA
MIXED USE ZONING
ALSO MIXED USE ZONING
To improve our quality of life create
harmonious beautiful built environment to
enrich the lives of its inhabitants

23
WAYS TO CONTROL DESIGN
HISTORIC/CORRIDOR
  • Must be tied to a historic district or a tourist
    corridor leading to a historic district
  • Historic district may be local (not State or
    Federal)
  • A.R.B. not strictly required, but intended

24
WAYS TO CONTROL DESIGN
HISTORIC/CORRIDOR
  • EXAMPLES
  • Leesburg
  • Portsmouth
  • Charlottesville
  • Lexington
  • Suffolk
  • Albemarle Co.

25
WAYS TO CONTROL DESIGN
CONVENTIONAL ZONING
  • Design controls through zoning standards (must be
    measurable - height, setback, etc.)
  • Design control through Site Plan review (staff
    administered usually not architectural review)
  • Separate district (TND or overlay)
  • Still need to be measurable standards to be in
    the Zoning Ordinance

26
WAYS TO CONTROL DESIGN
FORM BASED CODES
  • Dozens of localities nationwide are implementing
    Form Based Codes

27
FORM BASED CODES A New Trend in Design Control
28
A Method of Implementing the Principles of New
Urbanism
  • Walkable, human-scale streets, spatially-defined
    by building facades to create outdoor rooms
  • Interconnected street network
  • Mixed-uses in a fine-grain of buildings, uses,
    and streets
  • Usable, spatially-defined public spaces
  • Prominent civic buildings
  • Parking on-street and behind buildings
  • Multi-modal transportation and good congestion
  • Focus on urban design rather than architectural
    design

29
THE CONVENTIONAL SYSTEM
EUCLIDEAN ZONING
  • Focuses on separating and buffering land uses
  • Mainly controls Use Density
  • Secondary control of Management
  • Control of Form is incidental
  • Often implemented as a floating zone
  • Many words few graphics

31
THE EMERGING SYSTEM
FORM BASED CODES
  • Primarily control Urban Design and Spatial Form
    of Public Spaces
  • Less control of Use Density
  • Implements public policies regarding Urban Design
  • Not typically floating zones
  • Many graphics fewer words

32
The Results of TND and FBC
33
SUMMARY OF PURPOSE Form-Based Codes aim to
ensure (not just allow) that new development
will be compatible in character and scale with
traditional development without (necessarily)
using Architectural Review procedures
34
  • GENERAL DIFFERENCES
  • Conventional zoning districts contain no graphic
    depictions of standards
  • Conventional zoning districts often function as a
    floating zone rather than a set of regulations
    that apply to an existing urban fabric
  • When FBC is implemented as a Floating Zone, the
    developer/applicant actually creates FBC for his
    site, and a PUD serves as a regulatory
    framework for the actual site-specific FBC.

FORM BASED CODES SOME PROS CONS
  • Provides more flexibility in land uses and
    density
  • Focuses on creating what you want, rather than
    avoiding what you dont want
  • Focuses on creating human- scale public spaces
  • Can achieve high quality urban design without
    architectural review
  • Fairly sophisticated tool needs time
    expertise to set up correctly
  • Proper administration depends on staff training
  • May be unfamiliar and complicated to the
    development community
  • Works best for areas with an established urban
    pattern

EXAMPLES

Arlington, VA Columbia Pike Form-Based Code
  • 5 Components
  • Definitions
  • Regulating Plans
  • Building Envelope Standards
  • Streetscape Standards
  • Architectural Standards

Arlington, VA - Columbia Pike Form-Based Code-
Regulating Plan
  • Shows how each site relates to adjacent
    properties and streets
  • Also provides a coding key for the building
    envelope standards

CONCLUSIONS APPLICATION TO NEW KENT COUNTY, VA?
63
  • ISSUES
  • Does this kind of tool make sense in New Kent
    County?
  • What are key policy or regulatory
    issues/questions you have?
  • How would you like to see future growth areas in
    the County develop how should they look and
    feel (form and character)?
