If this occurs, replace the <br /> fence or remove the trapped sediment. <br /> • Sediment deposits shall either be removed when the deposit reaches <br /> approximately one-third the height of the silt fence, or a second silt <br /> fence shall be installed. <br /> I • If the filter fabric(geotextile) has deteriorated due to ultraviolet <br /> breakdown, it shall be replaced. <br /> I Pending height POST SPACING: <br /> max.24- 7'tea. on open rune <br /> Top of Fabric <br /> 4'MIMIC•n pooling areas <br /> ' . •, stilt <br /> I Attack fabric to h <br /> upstream side N put ' <br /> FLOW t <br /> ,441 <br /> Drive ever each side N r POST DEPTH: <br /> set Niece 2 W 4 Sr... % As meek below pound <br /> I wtth device•wtehy S as fabric above pound <br /> SO p.aJ.or•rester :. <br /> f Mogen&attachment <br /> 100%cetaps.. 100%e•tep.CS.I doublet strenoth <br /> /, mu,.•'kiF!i4f <br /> /\\/\\/\/ \ \\\\\\\\\ \\\ :.i:. 1 <br /> //:\/.\//� \\///\\/\\/\\/\\ ATTACHMENT DETAILS: <br /> 4 4/ � � '+ t• / / �/\\\ •Gather labdc at posts.I needed <br /> . <br /> / \\j\\ \\\//\/ •Wise three ties per pol a/within lop S'o/rabic. <br /> /\/\/\/ s \\ \ \ Position each tie diagonally.puncturing holes wstcaly <br /> /\\ /"•/ f �\\/' j a minimum of t'apart. <br /> iii \ \ •Hang each on• and � <br /> No more than 24'of a 36'fabric I .c tie <br /> ties so or t wire.. securely <br /> is allowed above ground. <br /> Rol of sit fence <br /> Post <br /> P installed <br /> I <br /> compaction <br /> 0 /Fabric Am <br /> q' . <br /> aboveSat fence ra <br /> \ 'fir-�-`—�� /;t1��t-.- <br /> ,c7;_- -:`' r ;"�' ram' <br /> t P' �� f ` �r ✓�6.4 ,y.. .yr r. . <br /> ),>it' ..Y-^L—s,VM.,\>ssr.II.-,,' <br /> • " 4‘'ri r ihi//nd it. . r,�.`err. r. x• <br /> ,�tr �P;���?(r�•i��' '.. \\��\'„„ �h 'ice ?f0-30fTIfT1 ��� • 1$!e% <br /> `0.4- ' •�! +%Cam-_: „„��\�,\\\\\\\\\\\\\\\\.. j ,/ti ,., <br /> r, <br /> Horizontal c Niel pit Siting blade <br /> (76 mm htAdifh) (18 rtxn width) Completed Metalation <br /> IVibratory plow is not acceptable because of horizontal compaction <br /> Figure 4.20—Silt Fence Installation by Slicing Method <br /> I <br /> I4-98 Volume II— Construction Stormwater Pollution Prevention February 2005 <br />
