Execution <br />1. Schedule <br />Site preparation and reseeding is to be done between October 10 and October 30, <br />2008, when temperatures are not expected to be above 90°F and the rainy season is <br />not expected to be underway. Though the erosion control layer of hydrostraw will <br />reduce seed predation by birds and small mammals some will still find and eat some <br />seed before it germinates. Because we rely on natural rainfall to germinate the seeds, <br />waiting until October shortens the length of time between application and germination. <br />This schedule will reduce the number of seeds eaten. <br />2. Site Preparation <br />a) Mow the existing vegetation on the site reducing the stubble to a minimum height <br />of six inches with a maximum height of 10 inches. <br />b) Leave the clippings where they fall. <br />c) A flail mower should be used rather than a rotary mower, but this is not required. <br />The flail mower breaks the clippings into smaller pieces, which decompose faster <br />adding to the organic components of the soil. <br />d) Disk minimum four inches deep in one direction. <br />e) Apply amendment. <br />f) Disk again cross -wise to the first disk direction. <br />g) Break up clods with a minimum 2 passes with a ring -roller (clod buster). <br />Additional fine grading may be necessary in order to create a smooth <br />surface suitable for drill seeding. <br />3. Seeding <br />a) Use seed mix presented above. <br />b) Thoroughly mix the seed and any necessary filler. <br />c) Drill seed using a range drill specifically adapted for large, long awned native <br />grass seeds. Range drill shall be calibrated on site in the presence of a County <br />representative to demonstrate that the seed is delivered at the specified rates. <br />d) Place seed between 0.5 inch and 1.25 inches deep and the soil surface <br />compacted lightly over the seed in the furrows. <br />e) Drill seed at right angles to the existing rows as much as possible where some <br />existing native grasses currently exist. <br />Driving at right angles to existing rows will prevent long swaths of overlap. <br />This minimizes damage to existing plants and minimizes competition <br />between new seed and existing plants. <br />Driving at right angles to existing rows may inoculate some existing <br />grasses without causing significant damage to the row as a whole. <br />ET Closure Cap Reseed 2 Foothill Sanitary Landfill <br />October 17, 2008 San Joaquin County Pub Works/Solid Waste <br />
