Summary
COUNCIL GOAL: Operational Excellence
MEETING DATE: February 7, 2017
DEPARTMENT: Development Services / Engineering
CONTACT: Robyn Root, P.E., P.T.O.E., Traffic Engineer
RECOMMENDED CITY COUNCIL ACTION:
• Approval of this Ordinance.
ITEM SUMMARY:
• This Ordinance will establish a speed limit on Wilmeth Road of 40 mph from a point 140 feet west of Ridgeway Drive westward to the new city limits at approximately 1400 feet west of Ridgeway Drive.
• This Ordinance will also re-establish a speed limit on Wilmeth Road of 40 mph from Lake Forest Drive to Ridgeknoll Avenue.
BACKGROUND INFORMATION:
• The new lanes of Wilmeth Road have been constructed adjacent to the Wilmeth Ridge and Auburn Hills subdivisions. These lanes of Wilmeth Road have been opened to traffic and thus a speed limit needs to be established on this extension of Wilmeth Road.
• When developing a recommendation for a speed limit, the following factors should be considered:
o The design speed of the roadway.
o The measured 85th percentile speed.
o The established speed limit on adjacent section of the same roadway.
o The adjacent land uses along the roadway.
• A design speed of 45 mph was used for construction of this arterial, along with the rest of the corridor.
• The area is zoned residential with new residential developments along this new section of Wilmeth Road with construction underway.
• The established speed limit along Wilmeth Road from a point 140 feet west of Ridgeway Drive to Ridgeknoll Avenue is 40 mph.
• Due to the above factors, a proposed speed limit of 40 mph is recommended on Wilmeth Road from a point 140 feet west of Ridgeway Drive to the new city limits approximately 1400 feet west of Ridgeway Drive.
• In 2013, per Ordinance 2013-02-013, the speed limit on Wilmeth Road between Lake Forest Drive and Ridgeknoll Avenue was inadvertently removed when the speed limit was extended on Wilmeth Road from Ridgeknoll Avenue to a point 140 feet west of Ridgeway Drive. This Ordinance will re-establish the speed limit of 40 mph on this section of Wilmeth Road.
FINANCIAL SUMMARY:
• The installation of the speed limit signs associated with the agenda item is in the operating budget of the Engineering Department.
BOARD OR COMMISSION RECOMMENDATION:
