Height: Equals the vertical distance measured from the lowest elevation of the outside
limit of the dam (usually the downstream toe) to the emergency spillway crest,
or top of emergency spillway gates if so equipped. In unusual circumstances
where a dam does not have an emergency spillway, the height is measured to
the crest of the dam.
Capacity: Equals the storage capacity of the reservoir when the storage level is at the
crest of the emergency spillway, or at the top of permanently mounted
emergency spillway gates in closed position. In usual circumstances where a
dam does not have an emergency spillway, the capacity is measured to the
crest of the dam.
FEES:
A.R.S. § 45-1204 authorizes the director to collect a filing fee “based on the estimated cost of
the dam but in no event shall the fee exceed two percent of the estimated cost.” A.A.C. R12-
15-151 sets the application filing fee for the first $100,000 of dam cost at two percent of the
estimated cost, 1.5 percent for the next $400,000, one percent of the next $400,000, and one
half percent for the remainder over $1,000,000. The fee for a safety inspection is $100 plus $2
per foot of dam height per inspection.
