1 <br />1 <br />1 <br />WCA/CWA Wetland Application <br />Gervais Hills <br />GES Project No. 2004.040 <br />June 16, 2004 <br />Page 5 <br />(25B) — Prairie Sedge Meadow Mix (seed mix presented in Appendix B). The <br />central marsh portion of the central and southern wetland basins is expected to <br />be colonized by native hydrophytes via seed transport from other wetlands in the <br />area. The northern basin is expected to result in a Type 2 inland fresh meadow. <br />After final grading has been completed, the areas to be seeded will be cultivated <br />with a light disking and dragging. Then the herbaceous seeding will be <br />broadcast over the sites in the ratios and rates specified in the MnDOT seed mix. <br />After seeding, the sites will be lightly dragged and cultipacked to ensure good <br />seed to soil contact. <br />A permanent conservation easement will be placed over all of the mitigation <br />wetland areas. <br />Table 1.

These requirements (per Minn. Rule 8420.0620) are as follows: <br />1) Description of the project location, size, current wetland type (Cowardin <br />classification), and desired wetland type (goal). <br />2) A comparison of the as -built specifications versus the design <br />specifications (first annual monitoring report only) and a rationale for <br />significant changes. <br />3) Hydrology measurements: seasonal water level elevations or areal <br />coverage measurements during the period April through October. <br />4) A map of plant communities within the boundaries of the replacement site, <br />including hydrologic indicators observed. <br />5) Color photographs of the project area taken any time during the growing <br />season. <br />Annual mitigation monitoring reports will be submitted to the Ramsey - <br />Washington -Metro Watershed District and U.S. Army Corps of Engineers as <br />required in their respective permits and approvals. <br />
