Review Draft Eastern Gateway Wetland Restoration Site -- Annual Report <br /> reached design elevations as specified on the grading plan, there was still fill <br /> material in some parts of the site. It is assumed that this fill material most <br /> likely was placed on the site prior to the 1962 topographic survey(check this ?). <br /> A decision was made to continue excavation in those areas where native soil <br /> had not yet been reached. Unearthing the native soil was considered a critical <br /> aspect of the excavation. After excavation was completed, the site was finish <br /> graded and then raked to loosen the top 3 -4 inches of soil in preparation for <br /> 'seeding. _ <br /> The original design plans estimated 10,604 cubic yards of fill material would be <br /> removed from the site. The decision to excavate to reach native soil resulted in <br /> an additional 9,279.51 cubic yard of fill being hauled off site. In all 19,883.51 <br /> cubic yards of fill were removed from the site. The result of this additional <br /> excavation was an increase in the total number of wetland acres restored. The <br /> original grading plan estimated a total of 6.38 acres of wetland would be <br /> restored. However, the as-built survey showed a total of 7.29 acres were <br /> restored. The difference can be accounted for by the decision to extend the <br /> excavation area to remove all earthen fill material from the site. <br /> Planting list <br /> These are the species and amounts of seed that were sown at the East Gateway <br /> wetland mitigation site in the fall/winter of 1993 - 94: <br /> Graminoids: <br /> Agrostis exarata 0 38 lbs <br /> Beckmannia syzigachne (approximately 1.0 lbs.) <br /> Carex densa 1 20 lbs <br /> Carex leporina 0 36 lbs <br /> Carex unilateralis 0 83 Ibs <br /> Deschampsis cespitosa 18.5 lbs <br /> Eleocharis palustris 0 78 lbs <br /> Glyceria occidentalis 0 05 lbs <br /> Hordeum brachyantherum 4 38 Ibs <br /> Juncus tenuis 0 21 lbs <br /> Juncus oxymeris 0 50 lbs <br /> Forbs: <br /> Aster hallii .... 0.84 lbs <br /> Boisduvalia densiflora 0 19 lbs <br /> Brodiaea hyacinthina 0 02 lbs <br /> Camassia quamash 5 00 lbs <br /> Downingia elegans 0 97 lbs <br /> Eryngium petiolatum 0 25 lbs <br /> Gentiana scpetrum (small amount) <br /> Page 7 <br />
