(1) Curves. The minimum radius of curvature on the centerline shall be 500 feet for primary or secondary thoroughfares, 200 feet for collector streets and 100 feet for minor residential streets.
(2) Grades. Maximum grades shall not exceed six percent for primary or secondary thoroughfares or twelve percent for collector or local streets. The minimum grade of all streets shall be 0.8 percent.
