Final Mitigation Plan for Long Hollow Reservoir La Plata River Mitigation Site (Permit No. 200375243) • At least six piezometers will be installed at the site and measured semi-monthly during the growing season (April - October). • Fixed photograph points will be created after construction and photographs will be taken each year for the monitoring report. • Observations on wildlife and waterfowl use of the area will be made. This will include direct observations of usage and indirect evidence (e.g., tracks, scat, grazed vegetation, etc.). 2.10 Long-Term Management Plan The Applicant has entered into a contract with BWC to perform the mitigation monitoring at the La Plata site required by the Section 404 permit. The contract with BWC is for a five-year period, starting when the mitigation is constructed. The mitigation sites will be observed and plans prepared for any corrective actions (CAs) needed. Bids will be obtained to implement CAs. Follow-up monitoring will then be completed to assess the success of the CAs. In terms of funding, it is proposed to escrow ten percent of the total mitigation construction cost for CAs. The mitigation will be protected through execution of a conservation easement (see Appendix B). 2.11 Adaptive Management Plan CAs will be implemented based on observations or data showing that at least one "trigger" is met at a site. Possible CAs are listed in Table 3. The list of CAS in this table is not exhaustive and other CAs may be identified. The most important part of the process is to identify the reason(s) for the problem, and to formulate a CA to address the problem. Oftentimes, more than one action may be needed. For example, the failure of wetland plants to become established is usually due to inadequate hydrologic conditions to sustain the species planted. Therefore, the first step is to remedy the hydrologic conditions, and the second step is to plant additional plants. August 2010 Bikis Water Consultants, LLC Page 11
