Designing and
Analyzing Boundaries
using Parcels
In the previous chapter,
you completed the road-design portion of the
example project by creating and displaying cross sections. With the roads
in place, it's now time to look at another aspect of the design: the layout of
real-estate lots. Although the road design and lot layout are very different
types of designs, they are still dependent on one another because the roads
determine the front boundaries of the lots. In the example project, you won't
return to road design; but in a real project, there are often adjustments to
the road layout that can affect the parcels as well as other design aspects.
As the designer in this project, you'll be asked to design the layout of
the single-family lots as well as open space areas, community areas, utility
easements, and so on. The developer makes money by selling the lots, so
the more lots there are to sell, the more profit that can be had. So why not
make a thousand tiny little lots? Well, of course, if a lot is too small to fit
a house, it will be nearly useless and won't sell. In addition, other aspects
determine minimum size requirements for lots, such as the market the
developer is targeting and/or zoning laws. Your job as the designer will
be to create as many lots as possible while meeting these minimum size
requirements.
