Post by aidai want useful principles for density
determination(e.g: the urban design(or traffic) guidlines and their
relation in density determination??would you plz help me ..
urban density is dependent on
1) Law/Zoning Ordinance/politics -- of which the most significan
factor is building height limitation
(most planner work to gradually increase building height /
skyline.). The US
Supreme Court ruling which gives local government the ability
to take lands to create
private commerical zones in the name of public domain allows
the politics
of big money to plays a even larger role than before.
2) Cost/Economics
( when buildings are taller than six stories high - the
construction
methods switches from bricks and sticks to reinforce concrete
and a steel superstructure which is more expensive. Bigger
building
also require bigger and more expensive foundations - the
increase
capital required for urban building requires a much more
robust
economy--- big money -- to finance)
3) Physical Infrastructure - maximum capacity of infrastructure
restrict the practical
density level that can be achieved.
a) an extensive roads/mass transit is needed to handle traffic
b) parking - expensive structured parking is usually a necessary
for urban environments
c) water/sewer capacity
d) electrical grid
e) for residential density
school system
recreation
police/fire/rescue services
other public facilities (e.g. public health care)
