M Shoreland area identified in a zoning ordinance. <br /> N Floodplain area identified in a zoning ordinance or map. <br /> VeQetative Communities <br /> The following plant communities were observed: <br /> (See Appendix A for details on the Dominant Species per plant community) <br /> Shallow Marsh Type 3, PEMC. This community had a vegetative index of low and comprised 0 percent of <br /> the entire area. <br /> Functional RatinQs <br /> Function Rating Comment <br /> Vegetative Diversity Low If vegetation is present, the primary communities are compromised by <br /> extensive invasive and/or non-native species. Ongoing maintenance will <br /> be necessary to restore native ecologic communities, although the <br /> presence of invasives upstream will limit the success of restoration <br /> efforts. <br /> Additional stormwater Moderate Sediment removal would improve the ability of this site to maintain water <br /> treatment needs quality. <br /> Maintenance of Moderate There has been some degree of human alteration of the wetland <br /> Hydrologic Regime hydrology, either by outlet control or by altering immediate watershed <br /> conditions. However, the wetland retains some of the hydrologic regime <br /> similar to the original wetland type, either in part of the wetland or <br /> overall to some extent. Because of the interference (whether active or <br /> inadvertant), some characteristic vegetative communities have likely <br /> been affected, as also have the functions of flood attenuation, water <br /> quality and groundwater interaction. <br /> Flood/Stormwater/Att Moderate The wetland provides some flood storage and/or flood wave <br /> enuation attenuation. It may have either an altered or unrestricted outlet, <br /> disturbed wetland soils, thin or little emergent vegetation (with channels) <br /> or it may be situated high in a watershed with a low proportion of <br /> impervious surfaces, moderate runoff volumes, loamy upland soils, and <br /> one or more other wetlands present within the subwatershed. <br /> Downstream Water Moderate This wetland has some ability and opportunity to protect downstream <br /> Quality resources. The ability of the wetland to remove sediment from <br /> stormwater is determined by emergent vegetation and overland flow <br /> characteristics. A high nutrient removal rating indicates dense <br /> vegetation and sheet flow to maximize nutrient uptake and residence <br /> time within the wetland. The opportunity for a wetland to protect a <br /> valuable water resource diminishes with distance from the wetland so <br /> wetlands with valuable waters within 0.5 miles downstream have the <br /> greatest opportunity to provide protection, as do those that receive more <br /> (and less-treated) runoff. <br /> Page 2 of 4 <br />
