Construct outlet ditch according to specified grades or proposed contours when indicated on the plans. When gradesor proposed contours are NOT specified on plans; construct ditch using either of the following options: i) Construct ditch at the minimum depth indicated above, maintaining the minimum depth while constructing the ditch on a slope that mimics the natural terrain/topography. (Typically used when terrain has positive slope in the direction of flow).; OR ii) Construct ditch on a minimum 0.5% grade (1% desirable), maintaining at least the minimum ditch depth. (Typically used when terrain is flat or terrain slope is opposite the direction of flow - "bucking grade"). ---Sometimes a combination of these two methods may be required along the entire length of the ditch. 2. Construct temporary diversion diches along permanent swales/ditches as needed during construction.SWALE SECTION SOILSTOCKPILEDOUBLE SILT FENCEW/OUTLET (TYP.)EARPSBORO-CHAMBLEE ROAD - S.R. 1723

Construct outlet ditch according to specified grades or proposed contours when indicated on the plans. When gradesor proposed contours are NOT specified on plans; construct ditch using either of the following options: i) Construct ditch at the minimum depth indicated above, maintaining the minimum depth while constructing the ditch on a slope that mimics the natural terrain/topography. (Typically used when terrain has positive slope in the direction of flow).; OR ii) Construct ditch on a minimum 0.5% grade (1% desirable), maintaining at least the minimum ditch depth. (Typically used when terrain is flat or terrain slope is opposite the direction of flow - "bucking grade"). ---Sometimes a combination of these two methods may be required along the entire length of the ditch. 2.

Construct outlet ditch according to specified grades or proposed contours when indicated on the plans. When gradesor proposed contours are NOT specified on plans; construct ditch using either of the following options: i) Construct ditch at the minimum depth indicated above, maintaining the minimum depth while constructing the ditch on a slope that mimics the natural terrain/topography. (Typically used when terrain has positive slope in the direction of flow).; OR ii) Construct ditch on a minimum 0.5% grade (1% desirable), maintaining at least the minimum ditch depth. (Typically used when terrain is flat or terrain slope is opposite the direction of flow - "bucking grade"). ---Sometimes a combination of these two methods may be required along the entire length of the ditch. 2.
