Good morning Jeff,
In response to your question about traffic calming on Bergman Ave see ACHD policy below. It appears that the plan set
was designed using two of the traffic calming and speed control measures discussed below.
7208.3.7 Speed Control and Traffic Calming
Design of local commercial street systems, where higher pedestrian activity is anticipated, should discourage excessive
speeds by using passive design elements. If the design or layout of a development is anticipated to necessitate 7200 - 49
Adopted: Revised: Res. 469 (7/13/94) Res. 675 (1/29/03); Res. 690 (10/15/03); Ord. 201 (4/12/06); Ord. 211 (12/15/10);
Ord. 233 (1/25/17); Ord. 236 (11/29/17); Ord. 238 (12/12/18) future traffic calming implementation by the District, then
the District will require changes to the layout and/or the addition of passive design elements such as horizontal curves,
bulb-outs, chokers, etc. The District will also consider texture changes to the roadway surface (i.e. stamped concrete) as
a passive design element. These alternative methods may require a maintenance and/or license agreement. Passive
design elements are to be considered the preferred method to calm traffic and achieve the desired travel speed for the
roadway. Speed humps, valley gutters, stop signs, and cross drains are not an acceptable tool for traffic calming new
local streets.
