2. The county sprawl index variables were gross population density, percentage of popu
lation living at less than 1,500 persons per square mile (low suburban density), percentage
living
at greater than
12,500 persons per square mile (transit supportive), net population
density
of urban lands, average block size, and percentage of small blocks (less than
.01
square mile).
3. For a range of definitions of sustainable development see, for example, Beatley and
Manning 1998, Berke and Manta-Conroy 2000, Laurence 2000, Wheeler 2002.
4. In many respects, the agenda for sustainable development is the next natural progres
sion in the evolution
of planning history.
Since the 1970s, the planning field has experi
enced a gradual expansion
of the notion of planning, from narrow considerations of zon
ing
and subdivisions to broader public-interest goals focused on growth management.
5.
Several documents indicate the detailed and specific guidelines and standards for
New Urban development projects ( Calthorpe 1993, Duany and Plater-Zyberk 1991, Duany,
Plater-Zyberk, and Speck 2000).
6. Donaghy and Hopkins (2004) criticize the concept of a network of plans, asserting
that it assumes a command-and-control structure of planning and decision making that
ignores markets and diverse planning efforts. They view the network framework as rigid
and unresponsive to the contingent needs for different types
of plans. They argue that the
network concept falsely assumes the existence
of a hierarchy of authorities that work in
harmony to create a seamless and internally consistent network of plans across spatial
scales.
On the contrary, we believe that network theory nicely represents the often messy,
overlapping,
and loosely coordinated planning institutions, initiatives, and processes that
make
up the context ofland use planning in a democratic society.
7.
Studies indicate that plans have a positive influence on land use patterns that support
natural hazard mitigation (Nelson and French 2002), economic development (Knapp, Deng,
and Hopkins 2001), and watershed protection (Berke et al. 2003).

Maryland,
on October 6,
2000.
