WHEREAS the Rural Integrated Roads for Growth (RIRG) program's minimum design standards for side slopes is 4:1 regardless of the height of the embankments of the road; and 

WHEREAS when the height of the road embankment is in excess of 3.0 metres this minimum side slope requirement of 4:1 results in the side slopes being beyond the 42-metre required minimum right-of-way resulting in a significant increase to project cost; and 

WHEREAS the Saskatchewan Highways Municipal Road Program Manual, 1996 minimum design standards for primary grid roads with an embankment height of more than 4.0 meters allows for a minimum side slope of 3:1; and  

WHEREAS the present Ministry of Highways design criteria on super grid roads with an embankment height of more than 3.0 meters allows for a minimum side slope of 3:1.   

BE IT RESOLVED the Rural Integrated Roads for Growth (RIRG) program's minimum design standards for side slopes be changed to the standards provided in the Municipal Road Program Manual,1996 for primary grid roads or required by the Ministry of Highways design criteria for large embankments encountered on super grid roads.
