also be inundated to become part of a reservoir. <br /> MITIGATION PLAN <br /> Disturbed and Mitigated Wetlands Constructio ents developed for the mitigation sites will <br /> include typical sections and site plans. A v etailed Wetland Mitigation Plan will be submitted to <br /> the Denver Regulatory Office for review and acceptance 000. <br /> Mitigation Site Description <br /> All wetland areas impacted will be mitigated on siteoan ki-z . Phase One is located just south <br /> of 1044, Avenue and just east of the South Platte River. Tkis-plrge of mitigation will be completed <br /> during the first year of the project and will include 6.86 acres of wetland creation (Drawing 3). In <br /> order to provide wetland hydrology, the topsoil of the area will be removed and the area will be <br /> excavated just below the water table. Once the proper depth is reached, the topsoil will be replaced to <br /> bring the soil surface to the water table and the area will be planted and monitored. <br /> _Rhase4tiwn of the mitigation plan is located just north of 100 h Avenue and east of the South Platte River <br /> and will be a remnant of the excavation of Area Two (Drawing 3). The site will begin as an open water <br /> area 30 feet deep and encompassing approximately 19.85 acres. Over five years, CAMAS will <br /> systematically fill the area from the south with fine particulate from the graveLwasbing operation. <br /> During the growing season Qf year five, f 11 will have be _gun to reach the water table surface in areas(3.5 <br /> ' feet below the ori�pal cn�l arfacn�g ---- - <br /> The point source of the fine particulate fill will then be relocated to the north each year for years six <br /> through ten. Start ig ysa six, approximately 20 the open water area will be fillad_cac_y=r until <br /> eKgigguad. At year ten, the entire 19.85 acres of open water area will have been filled, planted with <br /> wetland plants and properly monitored as indicated in the Special Conditions of the permit. <br /> Most excavated upland areas will be replaced by reservoirs and designated as conservation areas. All <br /> Wetland Mitigation areas for this project will be protected by being placed in a conservation easement. <br /> Mitigation Plan Detail <br /> Both phases of wetland mitigation are designed to replace disturbed wet meadow and seep areas. The <br /> plan establishes guidelines for providing a suitable soil medium, establishment of well-rooted plant <br /> materials and adequate hydrologic support for each-specific wetland habitat(Table 4)_ <br /> Planting will occur within the growing season(May through August). All plant material will be placed in <br /> 6 to 8 inches of topsoil. Where planting areas abut to open water, topsoil will be underlain by 10 to 12 <br /> inches of compacted sub-grade or structural fell. <br /> Vegetation Dominant species to be planted are willow, sedges, rushes, hydric grasses and emergents <br /> (Table 3). Planting will be accomplished in groupings that accomplish required densities equal to <br /> individual plants on specified centers, as follows: <br /> i? . herbaceous plants-1.5 OC (on center) small shrubs-76 OC <br /> • large shrubs-6-10'OC seeding at 25 #/acre PLS <br /> 5. <br />
