' • Practical Approa~ for Effective E & S Conwl - 82 <br />' Cp Preparation Ctuts <br />' Some technologies, such as erosion control blankets, require a certain amount of <br /> surface work (i.e. seedbed preparation); other technologies, such as hydraulic <br /> applications typically do not. These preparation costs should be considered and <br />I added to the overall costs for a particular practice. Fore example: <br /> A specification has been written for hydraulic seeding of a 3:1 slope which <br />' requires no surface preparation: The Cp factor would be $0. <br />' A specification might also be written for erosion control blankets on the same <br />slope which might call for blankets to be installed as to "manufacturer's <br /> recommendations" ,which would necessarily include some seedbed preparation <br />' such as raking, rock removal and perhaps application of seed and fertilizer Rrior <br />to blanket installation <br /> . <br />' While the material costs of the seed and fertilizer might be the same for both <br /> applications, the method of application varies. In hydraulic applications, the <br /> seed and fertilizer application occurs in one step and is part of the technology: <br />' In blanket applications, seed and fertilizer is applied in a separate operation, and <br /> adds, along with surface preparation, to the cost of application. The Cp for <br /> blankets is then greater than $0. <br />1 <br /> Field Notes: Some technologies, such as turf reinforcement materials (T'RM) or <br /> biotecl:nical composites (BC) require extensive preparation <br /> procedures. However, these costs can generally be included <br />' under Cl, Installation Cosrs. <br />' SUMMARY <br />' Using the example of the straw blankets applied over 1 acre on a 3:1 slope <br />requiring surface preparation, we could derive the following costs: <br />' CM $2,904.12 per acre <br />CA + $ 484.00 (for staples) <br />' Cl + $ 403.33 per acre <br />Cp + $ 200.00 per acre (approx) <br />' TOTAL COSTS (C) _ $3,991.45 per acre <br />or = $ 0.83 per sq yd <br />' or = S 0.09 per sq ft <br />' O 1995 IECA <br />
