Example Questions the Database Can Answer
1. Where are the septic systems based on found county septic
2. When was the septic system approved or inspected?

This map shows locations for septic permits recorded in the
Gallatin County Department of Environmental Health which could be
on the 1995 Gallatin County Road Book. Not all systems could be
To be found the address or subdivision, block and lot identification

2. Year Permit Issued:

About the Data
This theme records septic permit numbers and locations which could be
identified on the county road book based on street address or
block, and information. There are two pieces of information that
are important. The first is the septic number and the second is
date the septic permit was issued. Most of this information has
carried forward to the Geocode theme. This theme differs in
two important ways. In the septic theme if more than one septic
permit is listed at a single address, a unique point was spawned
for each permit at that location. This insures that each permit
a unique location. The unique points are 10 m from the
duplicate point location. The first point was spawned to the
the second to the south, the third to the west the fourth to the north,
and the fifth (if present) to the north east. This insures that
septic system has a distinct location so that each located septic
number can be found. This theme is useful if the user is interested
in identifying a septic permit at a unique location. This theme
differs from the septic them in the geocode or well/septic theme where
points were not spawned. There are many attributes for each
Most relate to location in some way or another. The attributes
the meanings of the attribute names in the
table for septic permits are listed in the attached html
Only permits in the LWQD have been located. The theme is in UTM
meters NAD83. Data was entered by coordinating the section
in the county Road Book with section corners on the public land survey
theme (plss) and points located were digitized by hand.
