WHY DO THIS NOW
•Recent Development identified the need to adjust speed limits
on adjacent roadways.
•Review of the Town Code identified the need to update the
Speed Zone Map.
OPPORTUNITIES
•Add new roadway segments
•Simplify speed limits
–Eliminate short speed zones
–Minimize number of occurrences where the speed limit is different
for the same segment of roadway based on direction of travel
–Use common beginnings/endings of speed zones
•Re -evaluate speed limits using engineering study and judgment
TOWN CODE 12-2-11
•“Reasonable and prudent maximum speed limits on roadways
located within the town limits are set forth on the town speed
zone map and accompanying table, adopted and amended
from time to time by resolution of the council, upon
recommendation by the town engineer and based on
nationally-accepted traffic engineering standards.”
•Last adopted: 2006
ARIZONA REVISED STATUTES
•ARS 28-701
–Speed limits in business or residential districts = 25 mph
–Speed limits in other locations = 65 mph
•ARS 28-703
–A local authority may increase the speed limit above 25 mph within
any business or residential district
–A local authority may decrease the limit below 65 mph outside of any
business or residential district
