3.12 	(5) natural drainage routes;
3.13 	(6) shorelines and riverbanks;

3.23 	(c) The commissioner shall establish a map to define bluffs and bluff-related features 
3.24 	within the Mississippi River corridor critical area. At the outset of the rulemaking process, 
3.25 	the commissioner shall create a preliminary map of all the bluffs and bluff lines within 
3.26 	the Mississippi River corridor critical area, based on the guidelines in paragraph (d). The 
3.27 	rulemaking process shall provide an opportunity to refine the preliminary bluff map. The 
3.28 	commissioner may add to or remove areas of demonstrably unique or atypical conditions 
3.29 	that warrant special protection or exemption. At the end of the rulemaking process, the 
3.30 	commissioner shall adopt a final bluff map that contains associated features, including 
3.31 	bluff lines, bases of bluffs, steep slopes, and very steep slopes.
3.32 	(d) The following guidelines shall be used by the commissioner to create a 
3.33 	preliminary bluff map as part of the rulemaking process:
3.34 	(1) "bluff face" or "bluff" means the area between the bluff line and the bluff base. A 
3.35 	high, steep, natural topographic feature such as a broad hill, cliff, or embankment with 
4.1 	a slope of 18 percent or greater and a vertical rise of at least ten feet between the bluff 
4.2 	base and the bluff line;
4.3 	(2) "bluff line" means a line delineating the top of a slope connecting the points 
4.4 	at which the slope becomes less than 18 percent. More than one bluff line may be 
4.5 	encountered proceeding upslope from the river valley;
4.6 	(3) "base of the bluff" means a line delineating the bottom of a slope connecting 
4.7 	the points at which the slope becomes 18 percent or greater. More than one bluff base 
4.8 	may be encountered proceeding landward from the water;
4.9 	(4) "steep slopes" means 12 percent to 18 percent slopes. Steep slopes are natural 
4.10 	topographic features with an average slope of 12 to 18 percent measured over a horizontal 
4.11 	distance of 50 feet or more; and
4.12 	(5) "very steep slopes" means slopes 18 percent or greater. Very steep slopes are 
4.13 	natural topographic features with an average slope of 18 percent or greater, measured over 
4.14 	a horizontal distance of 50 feet or more.
