Tall
Alternative 1--color. Total estimated square footage within this
model is about 5 million square feet of new space with most coming from
the yellow buildings (about half of 3+ million in the yellow and about
half of 2- in the blue). Model uses widely-spaced tall buildings
to keep increases in height along First and Ashley quite modest.
About one half million new square feet come from North Main (out of this
picture). This model has the widest variety in height (most 3D texture)
and lowest height changes in existing residential sections of the DDA.

At the meeting of April 1, Fred Beal presented
an alternative zoning scenario. This
animation shows Beal's changes; there are five seconds between successive
animation frames. The entire animation will repeat three times, after
which it will stop to show the entire zoning pattern. To reload the
animation, simply refresh the browser window. The zoning here simplifies
the existing zoning pattern; that is, spatial fragmentation is not as prevalent
in non historic districts.

up from meeting at DDA of February 2, 2004. The following set of Virtual
Reality files, with the sun in the south in a "high" position and with
terrain underlying the street pattern based on City contour files, was
created based on assigning
-
VR1: 300% to
all parcels in red, lot line to lot line (back and forth; side to side)
-
VR2: FAR to all
parcels in red by zoning category, lot line to lot line (back and forth;
side to side)
-
VR3: FAR premiums
as "by-right" values to all parcels in red by zoning category, lot line
to lot line (back and forth; side to side)
-
VR4: 600% to all
parcels in red, lot line to lot line (back and forth; side to side).
The set of VR files is organized roughly according
to amount of height, from least to most. The first two files are
quite similar to each other; the second one has two buildouts that are
one story shorter than in the first one (in C1A); it has more than that
that are one story taller than in the first one (in C2A). The last
two files (third and fourth) are even more similar to each other.
They are identical everywhere except that there are two buildouts, in the
S. University area, that are 400% on the third one, and 600% on the fourth
one.

building footprints are superimposed on parcels in the downtown core zones.
These VR experiments depict the downtown using actual building heights,
where known that are extruded from a topographic base. This base is a Triangulated
Irregular Network (TIN) made from a City of Ann Arbor contour map with
a contour interval of 5 feet. There are three sets of files for June
21:
-
VR
5: sun in the southeast (morning)
-
VR
6: in the south (noon)
-
VR
7: and in the southwest (afternoon)
This was done in order to suggest variation
in lighting conditions with season and with time of day. The lighting scheme
is designed for hill shading and is therefore really only useful for suggesting
shadow location as it does not account for light reflected from impervious
surface.
-
Model
with three different viewpoints entered
-
This set of files shows a sequence of views,
all with the same two camera angles--the first is a view of the entire
downtown and the second is a view looking west along Huron Street, from
a vantage point to the east of State Street. Use the navigation system
in the lower left-hand corner to see the views from these preset camera
positions; they offer a standard source for comparison as one switches
from model to model that the free-roaming form of navigation does not.
The red building in each model is a virtual building built on the southeast
corner of Huron and Fifth, across from City Hall.
