' <br /> � WETLA D DEFI IT <br /> N N ION <br /> ' According to the 1987 U.S. Army Corps of Engineers "Wetlands Delineation Manual" (1987 <br /> Manual;the document used by all delineators to define wetlandsj a wetland is "Those areas that are <br /> ' inundated or saturated by surface or ground water at a frequency and duration sufficient to support, <br /> and that under normal circumstances do support, a prevalence of vegetation typically adapted for life <br /> in saturated soil conditions." The Minnesota State Wetland Conservation Act Rules,Chapter 8420, <br /> � further clarifies that"...wetlands must: (1)have a predominance of hydric soils;(2)be inundated or <br /> saturated by surface water or groundwater at a frequency and duration sufficient to support a <br /> prevalence of hydrophytic vegetation typically adapted for life in saturated soil conditions; and(3) <br /> ' under normal circumstances, support a prevalence of hydrophytic vegetation." The I 9$7 U.S. Army <br /> Corps of Engineers Manual in Part II,item 24. states that, "The interaction of hydrology,vegetation, <br /> and soil results in the development of characteristics unique to wetlands. Therefore, the following <br /> � technical guidelines for wetlands are based on the three parameters, and diagnostic environmental <br /> characteristics used in applying the technical guideline are represented by various indicatars of these <br /> parameters." It is this premise by which SER ecologists has, in their professional judgment, <br /> � delineated the wetlands on the subject parcel described in this report. <br /> , Wetland Hydrology <br /> The most important wetland criterion is hydrology.The presence and persistence of water influences <br /> the vegetation types and changes soil morphology. Hydrology may be observed as standing water <br /> , (inundation),or may be observed as freestanding water within the soil pit ar auger hole(saturation) <br /> usually within Che upper ]2 inches. This is what would be considered primary hydrology indicators. <br /> Only one primary indicator is necessary to make the determination that wetland hydrology indeed <br /> � exists. The 1987 Corps Manual also has a range of hydrologic zones established based on period of <br /> inundation or saturation. These zones and the periods of inundation or saturation for each can be <br /> observed in Table 1 below. <br /> � Exce ted from the 1987 Manual,H drolo 'c Zones—Nontidal Areas <br /> Zone Name Duration Comments WeCland or Not <br /> � I Permanently Inundated 100% Inundation>6.6 ft. mean Not(Aquatic Habitat Zone,or Deep Water <br /> water de th Habitat) <br /> Semipermanently To Nearly Inundation detined as <br /> II Permanently Inundated Or �75 <_6.6 feet mean wate�r Wetland <br /> � Saturated <100%o de th <br /> I[I Regularly Inundated Or �25-75% Wetland <br /> Saturated <br /> � IV Seasonally Inundated Or <12.5- Wetland <br /> Saturated 25% <br /> Irre ularl Inundated or Many areas having these Wetland �f h dro h tic ve and h dric <br /> V g y >5-12.5% hydrologic characteristics � y p y �' y <br /> ' Saturated soils also present <br /> are not wetlands <br /> Intermittently Or Never Areas with these <br /> VI Inundated Or Saturated <5% hydrologic characteristics Not <br /> � are not wetlands <br /> � Svoboda Ecological Resources 744 Brown Road North <br /> Project No.:2007-081-03 2'] Ted Sehultze <br /> ' <br />
