**Please Note:At a minimum,you must establish good soil quality and depth in,all areas that will <br /> remain vegetated after your project is complete,including lawn and landscaped areas.One of the <br /> t_hrge following options must be chosen(Select Check Boxes as applicable)per BMP 12.20: <br /> OPTION 1-Amend Existing Soils in Place: <br /> Scarify or till existing subgrade to 4 inches depth(or to depth needed to achieve a total depth of 12 inches of <br /> uncompacted soil after calculated amount of amendment is added,see specific subsections below).Entire surface <br /> should be disturbed by scarification.Do not scarify within drip line of existing trees to be retained. <br /> Within Stormwater Drainage System locations or Landscaped Areas(10percent organic content)-Place and <br /> rototill 3 inches of composted material into 5 inches of soil(a total depth of about 9.5 inches,for a settled depth of 8 <br /> inches).As noted previously,subsoils below this layer should be scarified at least <br /> 4 inches,for a finished minimum depth of 12 inches of uncompacted soil.Rake beds to smooth and <br /> remove rocks larger than 2 inches diameter.Mulch areas with 2 inches of organic mulch. <br /> Within Lawn Areas(5 percent organic content)-Place and rototill 1.75 inches of composted material into 6.25 <br /> inches of soil(a total amended depth of about 9.5 inches,for a settled depth of 8 inches).As noted previously, <br /> subsoils below this layer should be-scarified at least 4 inches,for a finished minimum depth of 12 inches of <br /> uncompacted soil.Water or roll to compact soil to 85 percent of maximum.Rake to level,and remove surface <br /> woody debris and rocks larger than 1 inch in diameter. <br /> 0 OPTION 2-Stockpile Site Topsoils Prior to Grading for Reapplication: <br /> If placed topsoil plus compost or other organic material will amount to less than 12 inches: scarify or till subgrade <br /> to depth needed to achieve 12 inches of loosened soil after topsoil and amendment are placed.Entire surface <br /> should be disturbed by scarification.Do not scarify within drip line of existing trees to be retained. <br /> Stockpile and cover soil with weed barrier material that sheds moisture yet allows air transmission,in approved <br /> location,prior to grading. <br /> Replace stockpiled topsoil prior to planting. <br /> Within Stormwater Drainage System locations or Landscaped Areas(10percent organic content)-Place and rototill 3 <br /> inches of composted material into 5 inches of replaced soil(a total depth of about <br /> 9.5 inches,for a settled depth of 8 inches).Subsoils below this layer should be scarified at least 4 inches,for a <br /> finished minimum depth of 12 inches of uncompacted soil.Rake beds to smooth and remove rocks larger than 2 <br /> inches in diameter. Mulch areas with 2 inches of organic mulch or stockpiled duff. <br /> Within Lawn Areas(5 percent organic content)-Place and rototill 1.75inches of composted material into 6.25 inches <br /> of replaced soil(a total amended depth of about 9.5 inches,for a settled depth of 8 inches).Subsoils below this layer <br /> should be scarified at least 4 inches,for a finished minimum depth of 12 inches of uncompacted soil.Water or roll to <br /> compact soil to 85 percent of maximum.Rake to level,and remove surface woody debris and rocks larger than 1 inch <br /> in diameter. <br /> 0 OPTION 3-Import Topsoil Meeting Organic Matter Content Standards: <br /> Scarify or till subgrade in two directions to 6 inches depth.Entire surface should be disturbed by <br /> scarification.Do not scarify within drip line of existing trees to be retained. <br /> Within Stormwater Drainage System locations or Landscaped Areas(10 percent organic content)-Use imported <br /> topsoil mix containing 10 percent organic matter(typically around 40 percent compost). Soil portion must be <br /> sand or sandy loam as defined by the USDA.Place 3 inches of imported topsoil mix on surface and till into 2 <br /> inches of soil.Place 3 inches of topsoil mix on the surface.Rake smooth and remove surface rocks over 2 inches <br /> diameter.Mulch planting beds with 2 inches of organic mulch. <br /> Within Lawn Areas(5 percent organic content)-Use imported topsoil mix containing 5 percent organic matter <br /> (typically around 25 percent compost).Soil portion must be sand or sandy loam as defined by the USDA.Place 3 <br /> inches of imported topsoil mix on surface and till into 2 inches of soil.Water or roll to compact soil to 85 percent <br /> maximum.Rake to level,and remove surface rocks larger than 1 inch in diameter. <br /> Page 5 of 7 <br />
