The report identified four key design strategies. They may be summarized as:
−===Effective grading===
+===Effective Grading===
*Areas for vehicular and pedestrian traffic should be graded between 2 - 4% to reduce the chances of depressions forming over time ([https://www.ontario.ca/laws/regulation/110191 maximum permitted 5% for AODA]). Small depressions can result in ponded water icing over in the winter.

*Sub bases should be well compacted for the same reason. Preventing ponding and ice formation reduces the salting requirements for those surfaces.
