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). Compost or
other organic materials may be amended to meet the foregoing requirements.
o Exceptional Quality biosolids (EQ biosolids) may be used as a soil amendment, at a maximum proportion of 35% of the total
soil volume, and shall be well mixed with existing soil before or during application.
■The soil quality requirements shall be met by the following methods:
o Option 2: Amend existing site topsoil or subsoil in place.
▪Scarify or till subsoils to 4 inches of depth or to depth needed to achieve a total depth of 8 inches of uncompacted soil after
calculated amount of amendment is added. 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.
Remove and dispose of silt fence at the
completion of the project
