Post-Construction Soil Depth and Quality Notes: Required Elements: Soil retention: Retain, in an undisturbed state, the duff layer and native topsoil to the maximum extent practicable. Soil quality: All areas subject to the Standard shall demonstrate the following: ■A topsoil layer with a minimum organic matter content of 4% dry weight in planting beds and turf areas. The topsoil layer shall have a minimum depth of 4 inches, except where tree roots limit the depth of incorporation of amendments needed to meet the criteria. ■Compost and other materials shall be used that meet the following requirements: o The compost or other materials shall have a carbon to nitrogen ratio below 25:1. o Compost shall meet the definition of “compost” in the Agency's Solid Waste Management Rules or shall meet the contaminant standards in the Vermont Solid Waste Management Rules §6-1104(g)(6- 7), §6-1105(e)(8-9), and §6-1106(e)(7-9).

Except for within the drip line of existing trees, the entire surface shall be disturbed by scarification; ▪Amend soil to meet organic content requirements: ·PRE-APPROVED RATE: Place 1 inch of composted material with an organic matter content between 40 and 65% and rototill into 3 inches of soil, or ·CALCULATED RATE: Place calculated amount of composted material or approved organic material and rototill into depth of soil needed to achieve 4 inches of settled soil at 4% organic content. *Contractor to provide calculation and site sketch indicating areas used for calculations. ▪Rake beds to smooth and remove surface rocks larger than 2 inches in diameter; and ▪Water or roll to compact soil in turf areas to 85% of maximum dry density. Smooth and reshape existing composting pad. After steel has been removed. Silt fence to be used as construction limit demarcation until steel is removed.
