24VAC30-91-90: Discretionary authority

The department's resident engineers are authorized considerable discretionary authority regarding the design of subdivision streets functionally classified as "local." Such judgments should take into consideration the individual situation, but in no instance are the safety features, structural integrity, or traffic capacities prescribed by these requirements to be sacrificed. Meandering alignment and rolling grades are satisfactory, provided adequate stopping sight distances and reasonable alignment and gradients are provided to safely accommodate the projected traffic at the design speed.
