In areas devoid of quarried stone, soil cement is often economically <br />effective due to the availability and low cost of materials, and the ease of application. <br />Soil cement is recommended if vegetation is difficult to establish. It should be noted that <br />this method should not be used where traffic is expected due to the fact that soil cement <br />is not flexible. Effectiveness of soil cement on existing projects has not been adequately <br />evaluated. <br /> <br />FIGURE 4.8 <br /> <br />Geotextiles <br /> <br />Top of Embankment <br /> <br /> <br />+ <br /> <br /> <br /> <br />Slope I V on 3H <br /> <br />Streambed <br /> <br />Flow <br /> <br />Existing <br />Bankline <br /> <br /> <br />Geotextile Material With <br />Soil Fill And Seeded 1YJ>ical <br /> <br />tVon3H <br /> <br />Varies <br /> <br />Lin Anchor <br /> <br />N.W.S. <br /> <br />~ <br />Varies <br /> <br />Fill <br /> <br />Pin Anchor <br /> <br />-L <br /> <br />Costs can be expected to vary from $60 to $250 per linear foot with a projected <br />maintenance cost of $10 to $20 per year per linear foot of stream bank. <br /> <br />e <br /> <br />Tire Mats - Old automobile tires can be used to fonn mals or panels to protect the <br />streambank.
