Tables (like use tables) may not copy cleanly, so check any table against the official code.
Confirm anything here with Erda planning before you rely on it.
All uses in Zone 4 shall be governed by the underlying zone, except that any commercial or industrial use that has a storage, discharge or disposal of material onsite shall be a conditional use. A conditional use permit shall only be approved on the provision that such storage or disposal methods shall not permit any waste to leach into the aquifer. The planning commission, zoning administrator or health department may have the applicant conduct a study to show the neutralization or long-term effect by retention of such material in the geologic and hydrologic conditions of the site and/or aquifer.
