Body
DEPARTMENT RECOMMENDATION
Community Development Agency, Transportation Division (Transportation), recommending the Board approve and authorize the Chair to sign Resolution 150-2016 sanctioning a new speed restriction for the following:

A traffic study was conducted by Transportation in December 2015. The study concluded that the establishment of a posted speed limit on Greenstone Road was not justified due to:
1) The varied roadway geometrics of the northern and southern portions of Greenstone Road and;

This recommendation was presented at the May 4, 201...
