<br />3.2 Minimal Wetland Disturbance Alternative <br />Maintaining this additional 9.3 acres of wetlands results in losing the approximately 2.7 acres of <br />associated dryland, located within and adjacent to these preserved wetlands. The lost dryland <br />contains an estimated 86,000 tons of gravel that would be unavailable for mining. In addition, <br />unavailable gravel reserves within the 9.3-acre wetland are estimated at 298,000 tons. <br />Cumulative lost volumes associated with preserving these wetlands result in an estimated total of <br />about 384,000 tons of gravel made unavailable for mining. <br />Mining profits lost by under developing these significant gravel resources detract from overall <br />project economics making altemative unfavorable for project proponent and landowner. The <br />associated lost payments to landowner and project proponent amounts to approximately $223,000 <br />and $883,000, respectively. Gravel resources would be poorly utilized leading to further <br />environmental impacts as alternative County gravel sources are sought for future development. <br />The Texas Crossing would be constructed during reclamation, thus potentially creating critical <br />fish habitat for threatened and endangered fish species. Also, the 4.8 acres of undisturbed <br />wetlands will remain and probably not be affected by the adjacent mining activities as discussed in <br />previous section. <br />3.3 No Action Alternative <br />Under this alternative the tail water ditch wetlands would not remain undisturbed as proposed in <br />other alternatives. Mining the additional 4.8 acres of wetland would yield about 154,000 tons of <br />gravel available for mining. Developing these additional reserves increases landowner payments <br />by about $89,000 and project proponent's by approximately $354,000. Also, mining operations <br />would be uninterrupted by wetland removal and mitigation thus proceeding at a faster and more <br />economical rate. <br />Overall project economics depend on the associated costs required to construct span bridges <br />crossing jurisdictional waterways. This cost might be offset by reaping the benefit of maximizing <br />the yield potential of available gravel resources carried by the site. Potential environmental <br />impacts would be greater because of lost wetland habitat and function associated with wetland <br />excavation. These losses in wetland habitat would be permanent and not offset by wetland <br />mitigation. In addition, the Texas Crossing and outlet would not be constructed for potential <br />critical fish habitat, thereby increasing the non-native fish habitat. <br />3-2 <br />
