OF BAGS IN THE UNDERLYING ROW.
CONSTRUCTION OF A SANDBAG BERM PERPENDICULAR TO THE DIRECTION
OF FLOW SHALL INCORPORATE BAGS PLACED IN A "PYRAMID"
CONFIGURATION, WITH ALL INDIVIDUAL BAGS ORIENTED PERPENDICULAR
TO THE DIRECTION OF FLOW. THE BERM SHALL BE CONSTRUCTED WITH
A SPECIFIED NUMBER OF ROWS AT THE BOTTOM (IN CONTACT WITH THE
GROUND), WITH SUCCESSIVELY FEWER ROWS IN EACH OVERLYING
COURSE. THE UPSTREAM AND DOWNSTREAM FACES OF THE BERM SHALL
BE NO STEEPER THAN 1 1/2 FEET HORIZONTAL TO 1 VERTICAL. THE
SPECIFICATION FOR SPILLWAYS AND/OR OUTLET PIPES SHALL BE PER THE
RESPECTIVE GRADING PLAN DETAILS.
