The values from the web survey
are derived from the results of the Charlestown
Openspace Prioritization Project. The values
from the planning and conservation commissions were derived
through discussion with the commissions during planing workshops.
More information about this process
is available on this site.
These maps show areas that are currently vacant, and could
potentially have houses built on them according to the buildout
analysis. The parcels that are important to protect in dark
red, and areas that are less important in blue. The darker
the red, the more important it is to protect the parcel. To
see how this scoring system is created, go to the methodology
section.
There is very little difference between the results from
the planning and conservation commissions' and the web survey's
scoring systems. A map of the differences between scoring
is below. This map shows parcels that score higher with the
web survey's scoring system in red and parcels that are the
same in green. The parcels that score higher according to
the conservation commission and planning commission's scoring
system are in blue. This map does not show the amount of difference
in the actual scores, but this difference was not very great
for any of the parcels. The difference was no more than 16%
on any given parcel. More discussion about the evaluated the
consequences of the differences is in the potential
impacts section.
These maps should be used to evaluate the scoring systems.
If a policy is created using one of these scoring systems,
the parcels that are dark red will tend to be protected before
parcels that are blue. Of course, this will happen only if
there are several parcels that could be bought at any given
time and the town has to decide between potential purchases.
These maps also help identify parcels that should proactively
be pursued to be protected as openspace. The parcels that
score high, should be investigated individually to determine
if they can be protected.
Finally, these maps should help evaluate the scoring systems
themselves. The parcels that score high
should have characteristics that are compatible with
the town's goals. If not, there
is a flaw in the scoring system. This flaw should be fixed
before the scoring system is incorporated in the openspace
plan.
An in-depth discussion of evaluating
the point systems is in the potential
impacts section.
