SECTION 3.20.  STORM WATER CONTROL. The City Planning Commission (hereafter referred to as the COMMISSION) shall review and approve a storm water drainage plan for all classes of construction and property development prior to the issuance of any permits by the Building Inspector. The plan must include the following as a minimum:

1.) Provisions for storm water retention, if required by the terms of this ordinance.

2.) Plans for the controlled release of retained storm water into the Camilla storm water drainage system. (The rate of release cannot exceed predevelopment flow rates from the property being developed.)

3.) A topographic map of the property or sufficient spot elevations on the plan at critical points to confirm direction of storm water flow before and after development. Finished floor elevations must be shown.

4.) The approximate limits of any flood zone encroaching onto the property or a written statement that no part of the property is in a flood zone.

5.) Sizes of all existing and proposed storm water facilities on or near the property which will be used to drain the property. Calculations to support the sizing of all drainage structures shall be submitted simultaneously with the drainage plan.

6.) If the property to be developed is contiguous to a State route or proposes to use a State Department of Transportation (DOT) drainage system for storm water disposal, written evidence of coordination with DOT and copies of all DOT permits must be provided with the storm water plan.

The above described storm water plan shall be developed by and bear the stamp of a registered land surveyor or professional engineer, licensed to practice in the state of Georgia.

The above notwithstanding, a storm water plan shall not be required on:

a.) A single family residential lot of one (1) acre or less unless that lot is contiguous to a larger tract, which in the opinion of the COMMISSION is likely to be developed in the near future. In this latter case, the COMMISSION, at its discretion, may require a drainage plan for the entire tract.

b.) New construction, where the total area to be paved and/or to be covered by roof is less than 6,000 square feet. If, however, the property abuts a state right-of-way, written evidence of coordination with DOT will be required.

The developer must bear all costs associated with management of storm water on the property to be developed.
