WnRK.4HOP ON AMENDMENTS TO THE ZONING ORDINANCE: Commissioner Mills said he
had invited Rollin Johnson to the meeting to discuss placing septic tanks in the
Heronwood area.
The sanitarians said approval of any septic tank over 3,000 gallons comes
under the State. The only thing the county gives is an application rate and a
design flow rate. They can also look at tonography (site location).
It was explained that this particular area had a .4 application rate, which
means each square foot of drainage area is capable of taking .4 gallons of sewage
drainage per day.
The amount of useage per household is figured at 120 gallons per bedroom per
dav, so a three-bedroom home would use 360 gallons per day.
The three types of soils are Class 2, Class 3, and Class 4 (under Class 4 are
4-A and 4-B). These classes identify the application rates. Class 3 application
rates are .6 to .4. Class 4-A is .4 to .2. In Class 4-B, the rate is unsuitable.
The lower the application rate, the more drainage field is required.
Usually Class 2 soils are something that are not found in Piedmont or at
least in this section of the state. Class 3 and Class 4 are clay soils (fine loams).
A project the size of Heronwood would be approved on the state level because it
' is over 3.000 gallons. The State has to approve the design submitted from an
engineer. The local sanitarians would supply the soil data and make site visits.
