<br />n01SJ2 <br /> <br />Alternatives, Including Proposed Action <br /> <br />2-32 <br /> <br />remedial measures probably would be limited to rock touch ups and seeding and sprigging <br />with native species to encourage vegetation. <br /> <br />After operational commencement, aerial monitoring, field inspection, and landowner <br />contacts will be used to identify additional sites that may need protection. The same <br />selection criteria would be used for the new sites as for the original stabilization sites. <br /> <br />Additional details of the Sponsors proposed monitoring program are presented in <br />Attachment A to this report. <br /> <br />2.4.6.2 Wetlands Mitigation Sites - Monitoring and Performance <br />Standards <br /> <br />Wetlands will be created in areas where surface and groundwater are available in <br />sufficient quantities for natural growth of new vegetation. This may require earthmoving <br />or lowering of the ground surface elevation prior to planting. It may also be necessary to <br />irrigate some areas during the first growing season. <br /> <br />Wetland mitigation sites will be monitored until the later of three years after <br />establishment, or until full vegetative cover has been established. Monitoring will <br />include recording species diversity, cover, and shrub density. During the first growing <br />season, the sites will be observed three times to ensure proper establishment and growth <br />of vegetation. After the first year, monitoring will occur annually. Supplemental visits <br />may be scheduled after particularly high flow events. Remedial measures, including <br />overseeding, new planting, or hydrologic modification, will be taken if target success <br />rates are not achieved. <br /> <br />Performance standards that indicate success or failure of the mitigation effort will depend <br />upon the specific site and functional impact that is being addressed. Success rates will be <br />dependent upon planting density and methods. Generally, the goal will be to establish <br />100 percent vegetative cover with sufficient hydrophytic vegetation that the functional <br />loss being mitigated is replaced. <br /> <br />Beginning at the end of the first year of project operations, an annual report will be <br />submitted to the COE and Reclamation detailing implementation of the Wetlands <br />Mitigation Site and supplemental mitigation sites, planting efforts, and success rates. <br />Annual reports will be submitted until the later of three years after completion, or when <br />full vegetative cover (and functional replacement) has been achieved. <br /> <br />2.4.6.3 Uncompahgre River Wetlands and Riparian Vegetation Monitoring <br /> <br />In addition to the proposed mitigation sites, the Sponsors will monitor wetlands and <br />riparian vegetation along the affected reaches of the Uncompahgre River. This monitoring <br />will be used to ensure that sufficient mitigation has been established to mitigate Project- <br />related impacts, Because the Sponsors plan to mitigate, in advance, for wetland impacts <br />that may not actually occur (i.e. the Supplemental Mitigation), then there may ultimately <br /> <br />AS Lateral Hydropower Project <br /> <br />July2000 <br /> <br />, <br />J <br /> <br />.\~ ;... <br /> <br />~ <,. ~-, <br /> <br />"I <br />,- ",~ <br />--;~ -,:>! <br />J,i ~0 "~iii,-_"" ~ _:J~-.~-i:1i11 <br />
