Wetlands, Wetland Buffers, and Surface
Water
These coverages where used in both the buildout
and the openspace analysis.
The wetlands coverage comes from the RIGIS database.
The intended use for the coverage is land use planning, which
fits with the its use in this study.
The spatial resolution of this coverage is one
quarter of an acre. For buildout, this could have dramatic
effects on the number of houses that are estimated to be built
on each specific lot, but these effects will most likely not
be seen on the aggregate.

RIGIS Metadata
The wetland buffers were created in Arc Info
using the buffer command set at 300 ft. These buffers were
used for the openspace study. 50 ft buffers were created for
the buildout study. The spatial resolution of these buffers
is comparable to the spatial resolution of the original coverages.
Surface water is comprised of 2
coverages. The rivers are from the hydrolines
coverage, and the water bodies are derived from the parcel
coverage.
The hydrolines coverage was created
by interpreting aerial photographs, and has a resolution of
20 ft.
