Challenges Faced As written, the Citys Traffic Calming Policy requires a great

deal of staff time to get neighborhoods to the point of amaster plan adoption only for residents to find that they

dont have the support for plan implementation. Large neighborhoods face an especially difficult time

gathering majority support for even temporary measures.

Policy requires a Citizen Traffic Calming Committee but

does not provide a purpose for the group. Mature neighborhoods with offset driveway and other

geometric conditions often limit measure selection andplacement.


24/24

The Citizen Traffic Calming Committee has recommendedrevisiting the policy to improve the likelihood of successfulTraffic Calming implementation:

Require neighborhood support in the very earliest stages. Tailored impact areas to improve support ratios.

Reasonable time limits so City Staff and the Committee canmove forward if neighborhood support is not forthcoming.

Minimum point threshold from the Scoring Matrix forconsideration.
