development, much of it in a gated community
established about 20 years ago. In contrast, Jones
Creek is much less developed, and development
follows traditional patterns with agricultural land
and residences in the valleys (Figure 8.8).
Mountainside development was clearly
correlated with land value (Figure 8.9), largely
driven by the presence of Highlands, a town with
a large seasonal population located at over 1250 m
elevation. There was also a good correlation
between nitrate concentration and the extent
of mountainside development with two notable
outliers: Franklin, where 11% of the parcel
area is commercial, and Rabbit Creek, which
is the only catchment with extensive row crop
agriculture.
