7. The presence of a high groundwater table an wetlands on and adjacent to this site indicate that the soils and site conditions are probably not suitable for an infiltration basin. In an infiltration basin is no feasible, a wetpond will be requireu. 8. In general, no stormwater facilities, with the exception of necessary discharge systems, may be located inside wetland or stream buffer areas. 9. � On-site detention of stormwater runoff is required per �ity standards. 10.

Discharge of water to wetlands should mimic naiural discharges as much as is feasible. Point source discharges should not be created where they do not naturally occur. Techniques that result in dispersed discharge, such as dispersion trenches or buried pertorated pipe located at wetland buffer edges, can be used to mimic naturally occurring sheet flow into wetlands. 13. Natural wetlands may not be used to meet detention requirements for stormwater. In addition, stormwater detention is generally not allowed in wetlands created for mitigation. However, with certain types of mitigation wetlands, a restricted outlet and fluctuating water table is desired and designed feature of the wetland.
