§ 20-407. Permit required.

No person shall drain, excavate in the permanent or semi-permanent flooded areas of open water wetlands, or fill a wetland, wholly or partially, or otherwise impact wetlands without first having a wetland replacement plan or other determination approved by the city. Draining, grading, excavating, filling, removing healthy native vegetation, or otherwise altering or destroying a wetland of any size or type not subject to an exemption under section 20-417 of this article requires a wetland alteration permit. Activity in a wetland requiring a wetland alteration permit includes, but is not limited to:

(1)

Construction of new streets and utilities.

(2)

Creation of ponds or dams and alterations of the natural drainageways of watercourses. This shall only be allowed as part of a mitigation project, or to restore or improve the function and value of the wetland.

(3)

Installation of boardwalks and docks. Docks shall meet the additional requirements in section 20-920 Structures, Boats and Waterways of this Code.

(4)

Discharge of untreated stormwater runoff into wetlands.

(5)

Changes in wetland hydrology that result in an increase in the ordinary high water level of a wetland by more than 12 inches.
