The topsoil of the <br /> 2000 whiCi; i; "Table ldountain Lc am" and a deep soil that sho:7ld <br />draina,e <br /> , <br />provide most of tt:e corer, but all other top soil that will be buried <br /> in file spoil should also be r_move3, suitably stoc4:}:iled and protected <br /> fro;r. erosion. Such as diversions or s~,all dais. The topsoil s!~ould <br /> Trot be removed until absolutely necessary al:d only as t:Ie spoil area <br /> pro3resse;. The spoil will be level between the drainage side^,, but <br /> any needed slope; will be 3:1 or flatter.After a desired aTOUnt o: <br /> spoil has been placed to conclude a section, the topsoil silculd be <br /> placed over the spoil with a mini:rum cover of sic (6) inches. If <br /> there isn't enou,;h topsoil for a cover of six (E) icciTes the topsoil <br /> should be incorporated into the spoil by ~isF:in;. ,.c weathered cczl, <br /> or coal sF.ale will be laCt on the surfac° as they are extremely acid <br /> and will prevent ~,^rmination of grass seed. <br /> 20-25 ac. Seed ins: As a section oC spoil is covered by topsoil it bill be seeded <br /> to grass. ai,hteen (18) pounds of pure live seed per ac r= cf Fubescer,t <br /> wheatgrass, Luna variety <br />will be drilled bet.aeen April 15th to June 1st. <br /> , <br /> 20-25 ac. Deferred Grazing The seeded area will be protected :rem rrazin~ by <br /> domestic aniTals. The most desirable prot,.ctior, of the entire drainage <br /> xould be to exclude the ;;razing of domestic ani;rals. <br /> Structures for draina~c under spoil: hydrology of the drainage area <br /> was corputed and found to be 950 c.f.s. for a fifty years storm and <br /> 1200 c.f.s. for a hundred years store. A detailed en,;ineerin3 survey <br /> would need to be made for the correct size of pipe and inlet and outlet <br /> structures, but for an example only, with at least one (1) Ct, fall in <br /> 120 ft., and a 9 ft. head of water, a 10 ft. diameter CIdP would carry <br /> 1200 c. C. s. If a pipe to handle a hundred years storm is not feasible <br /> then dams should he constructed in the upper drainage area Lo slow the <br /> runoff and release it over a ~2 hour period. <br />• • <br />
