Road and Driveway Assessment

	High Risk (3) Modify Practice	Moderate Risk (2) Possible Hazard	Low Risk (1) Recommended	Your Rank
Road shape	Steep road, soft, berms on sides, no center crown; portions of the road wash out every year; cars are "swallowed whole."	Not much of a crown; some potholes, berms, or ruts; road sometimes soft; no water diversions.	Proper crown; has water diversions if road is long and steep; road always firm; no berms on sides.
Ditches	Steep sides (less than 2:1 slope); nothing to stabilize soil surface.	Sides somewhat steep (2:1 slope); only parts of the ditch are stabilized with grass or rock.	Gentle side slopes (3:1); grass or rock lined with filter fabric to secure surface.
Ditch turnouts	Road is steep and long with no ditch turnouts.	Only a few ditch turnouts; they have channelized water, sediment delta at end.	Frequent use of turnouts; spreads water in a thin sheet into a vegetated buffer.
