Preserved Wetland

Technical Standards for Preserved Wetlands

1. Determine the extent of the existing wetland by analyzing topography soil, moisture levels and plant material species.

2. Conduct and inventory of all existing plant species and classify by plant type scientific and common name.

2. Determine the depth shape and size of the wetland was well as all points of inflow and outflow.

3. Calculate holding capacity.

4. Determine outflow rate and the route of the storm water flow by inspection and or testing.

5. Augment by creating a 12”-18” deep forebay at in-flow point to facilitate maintenance and filtering. 

6. Limit impact to the wetland area by barricading with fencing during construction activities.

7. Minimum size shall be matched to the drainage basin that feed it. Most wetlands need to be at least 2000 sf 940’ X 50”) to function effectively.

8. Introduce mosquito fish (Gambusia holbrooki) into the wetland to keep the mosquito population under control.
