Kan. Admin. Regs. § 5-40-20 - Hazard classes of dams
(a) The hazard
classes of dams shall be determined from the following based on the location of
the dam, the hazards found within the inundation area, and the impact of a
failure of a dam:
(1) A "hazard class A dam"
shall mean a dam located in an area where failure could damage only farm or
other uninhabited buildings, agricultural or undeveloped land including hiking
trails, or traffic on low-volume roads that meet the requirements for hazard
class A dams as specified in subsections (b) and (c).
(2) A "hazard class B dam" shall mean a dam
located in an area where failure could endanger a few lives, damage an isolated
home, damage traffic on moderate-volume roads that meet the requirements for
hazard class B dams as specified in subsections (b) and (c), damage lowvolume
railroad tracks, interrupt the use or service of a utility serving a small
number of customers, or inundate recreation facilities, including campground
areas intermittently used for sleeping and serving a relatively small number of
persons.
(3) A "hazard class C
dam" shall mean a dam located in an area where failure could result in any of
the following:
(A) Extensive loss of life;
(B) damage to more than one home;
(C) damage to industrial or
commercial facilities;
(D)
interruption of a public utility serving a large number of customers;
(E) damage to traffic on
high-volume roads that meet the requirements for hazard class C dams as
specified in subsections (b) and (c) or a high-volume railroad line;
(F) inundation of a frequently used
recreation facility serving a relatively large number of persons; or
(G) two or more individual hazards described
in hazard class B.
(b) If there is a road across any part of the
embankment or a spillway, including the auxiliary spillway or service spillway
channel down to the receiving stream, the daily vehicular traffic shall be
considered in determining the hazard classification, in addition to the
criteria specified in subsection (a). The hazard classifications specified in
this subsection shall be used if these classifications are more stringent than
the hazard classifications required by subsection (a).
Hazard class Vehicles per day
A 0 through 100
B 101 through 500
C more than 500
(c) If any road in the inundation area does
not meet the criteria of subsection (b), the daily vehicular traffic shall be
considered in determining the hazard classification, in addition to the
criteria specified in subsection (a). The hazard classifications specified in
this subsection shall be used if these classifications are more stringent than
the hazard classifications otherwise required by subsection (a).
Hazard class Vehicles per day
A 0 through 500
B 501 through 1,500
C more than 1,500
