1.4 Wetland Management Standards Wetland management standards are proposed to maintain tolerable hydrologic and water quality changes in wetlands based on the goals stated for the management classifications. The recommended wetland management system (Table 1.1) presents a framework for management of storm water in and around wetlands as well as considering the regulation of impacts to wetlands and wetland mitigation; it is not meant to be used for specific wetland area designs. Replacement plans must also consider other laws that may apply, including local regulations, state Wetland Conservation Act rules, and U.S. Army Corps of Engineers 404 or other permit requirements. Additional investigations or evaluations, including detailed hydrologic modeling and modeling of nutrient loadings and removals, will need to be performed to determine final pipe sizes, pipe configuration, pipe elevations, pipe location, and site grading. 1.4.1 Wetland Hydrology Standards 7 Wetland hydrology management standards were developed to protect wetlands from hydrologic impacts. These standards present tolerable hydrologic changes in terms of bounce (difference between the peak flood elevation and the normal wetland elevation), inundation period (time that flood waters temporarily stored in the wetland exceed the normal wetland elevation), and runout control (elevation of the outlet). It is assumed that wetland impacts will be minimized and existing wetland functions and values will be maintained if these standards are implemented. 7 Standards shown in Table 1.1.
