THE SPECIES TO BE USED ARE LISTED BELOW. AT LEAST TWO SEPAPATE <br />(JUNCUS EFFUSUS) <br />PLANT SPECIES SHALL BE PLANTED. AN OVERALL DENSITY OF ONE PLANT PER <br />SQUARE FOOT OF SWALE BOTTOM IS REQUIRED. <br />SMALL -FRUITED BULRUSH <br />(SCIRPUS MICROCARPUS) <br />WETLAND VEGETATION PLANTED AFTER MARCH 15 AND BEFORE OCTOBER 15 WILL <br />GENERALLY REQUIRE IRRIGATION THROUGH THE FIRST SUMMER TO ENSURE PLANT <br />CATTAILS (TYPHA LATIFOUA) MA1 iE USED IN PLACE OF ANY OF THE ABOVE <br />SURVIVAL.

IN GENERAL, USE A 10-20-20 (N-P-K) FERTILIZER. HOWEVER, USE A NON- <br />(FESTUCA PRATENSIS) <br />PHOSPHORUS CONTAINING FERTILIZER IF THE SWALE IS BEING CONSTRUCTED I,. <br />THE SILVER LAKE DRAINAGE BASIN OR IN THE DRAINAGE BASIN OF ANY OTHER <br />REC'OP BENT GRASS 20% <br />PHOSPHORUS -SENSITIVE WATER BODY. <br />(AGROSTIS ALBA) <br />SOD THE SWALE IMMEDIATELY AFTER THE SIDES AND BOTTOM OF THE SWALE HAVE <br />RED FESCUE 10% <br />BEEN PREPARED.
