Topographic survey with WSB drone technology: Topographic survey to develop current <br />existing elevation data for the wetland bank site. <br />3. GIS based conceptual construction plans, vegetative plans, and monitoring pl ans for the <br />project. <br />4. Prospectus document and application: existing conditions, historical conditions, draft <br />project goals and outcomes, ecological suitability and sustainability, draft vegetation plan, <br />draft construction plan and draft monitoring plan, NHIS and SHPO data requests. <br />5. Draft site exhibit and conservation easement description boundary: Location of the site <br />and legal description including existing easements and historical data review. <br />6. Technical Evaluation Panel review meeting: correspondence with landowners, Local <br />Government Unit (LGU), BWSR, Soil and Water Conservation District (SWCD), and <br />USACE. <br />7. Hydrologic and hydraulic analysis: evaluate the watershed, subwatersheds, and <br />movement of water to the site based on modelling and surrounding land use. Evaluate <br />the wetland condition based on the proposed construction elements. <br />8. Hydrology monitoring: install water level data loggers and wells to conduct pre- <br />construction hydrology data of the bank site. <br />9. Respond to TEP/IRT Comments. <br /> <br />Task 3: Mitigation Banking Instrument (DMBI and MBI) <br />1. Site exhibit and final conservation easement description boundary: Location of the site <br />and legal description including existing easements and historical data. <br />2. CAD based final construction plans, vegetative plans, and monitoring plans for the <br />project. <br />3. Engineers Estimate: develop a construction estimate based on final design. <br />4. Mitigation Banking Instrument and application: existing conditions, historical conditions, <br />final project goals and outcomes, ecological suitability and sustainability, final vegetation <br />plan, final construction plan and final monitoring plan, final hydrologic and hydraulic <br />analysis. <br />5. LGU TEP field review and meeting, final wetland bank plan meeting correspondence with <br />LGU and USACE. <br />6. Level 2 wetland delineation. This delineation may be completed later upon further <br />establishment of the bank. <br />7. Respond to TEP/IRT Comments. <br />8. Bidding documents and administration. <br /> <br />Task 4: Wetland Bank Construction <br />1. Site Construction: includes contractor mobilization for grading, ditch plugs, and outlet <br />control structure installation. A detailed breakdown of the preliminary construction cost is <br />included in Appendix C. <br />2. Year 1 Restoration: Vegetation management will include a site-wide herbicide application <br />on invasives and selected tree removal in the spring or fall. Another site-wide herbicide <br />application would be completed during the late summer followed by either a controlled <br />burn or mowing in the fall or following spring. The site would be seeded with native <br />vegetation and supplemental plantings of trees and shrubs would be installed in the <br />wooded areas. Site construction would occur in the late fall or winter following initial <br />vegetation management to increase the amount of water on the site and to create less <br />desirable growing conditions for reed canary grass to reestablish. <br /> <br />Task 5: Wetland Bank Monitoring/Maintenance <br />1. Required five years of bank monitoring (years 1-5): vegetation surveys, hydrology <br />monitoring, maintenance recommendations, and annual summary reports. <br />2. Mitigation Certification: Certifying the bank with the TEP for final credit deposit. <br />3. Years 2-5 Restoration Maintenance: This includes vegetation maintenance that may be <br />necessary to establish native vegetation and meet performance standards. These
