Septic Suitability
High
Moderate
Low
| In the model, areas that are
most suitable for septic systems are indicated in green, and those that are
less suitable are in red. The
maximum value was 9, at areas where new septic systems should be developed
with care and old ones should be cited for repairs. These areas are characterized by high slopes and soil
types that drain too quickly to leach out nutrients. Areas that have low slopes and soils
that hold water for excessively long periods of time were also likely to have
low septic suitability. |
