The impactS <br />identified are those which can be expected to occur as a result of the proposed activities and <br />alternatives detailed in Chapter 2. The pOlentia] for successful mitigation of impacts to wetlands is <br />also discussed. Table 4-3, Wetland Acreage to be Impacted by Alternative, depicts the total acreages <br />to be directly impacted by the various alternatives. <br /> <br />I TABLE 4-l I <br />. .

No Action <br /> <br />Under Alternative A, the project area would essentially remain in its existing state, supporting <br />current land uses. The total acreage of wetlands and the characteristics of the plant communities <br />would not likely change significantly in the future, barring any unforeseen site developments or <br />alterations in recreation or grazing policy. <br /> <br />4.5.2.2 Alternetive B . Proposed RB8erYoir Expension <br /> <br />Under Alternative B, the primary impact to the wetlands resource would be the inundation of a <br />portion of the wetlands surrounding the reservoir as a result of the planned increase in storage <br />capacity. This inundation is a form of "filling" and is, therefore, considered to be an impact to be <br />addressed. A total of approximately 15.09 acres of wetlands would be affected as a result of this <br />Alternative. This acreage includes the wetland area to be inundated by the increased storage capacity <br /> <br />$::~:::z:;:,~~w;:;~~~~~...:W~~;::::r~~"0*:.....,:.}:%'7l{:<<<.,~~~::.::;:r:<'........x:::3m:::m:::;:::::i~>>3:::;';">>.:?::;:::<<''ii:,>0. <br /> <br />Page 4.16 <br /> <br />September 1993 <br />
