MEETING DATE: April 4, 2017
DEPARTMENT: Development Services / Engineering
CONTACT: Robyn Root, P.E., P.T.O.E., Traffic Engineer
RECOMMENDED CITY COUNCIL ACTION:
* Approval of the Ordinance.
ITEM SUMMARY:
* This Ordinance will establish a speed limit on Coit Road of 50 mph from Virginia Parkway to a point 525 feet south of Rambling Road.

? The design speed of the roadway.
? The measured 85th percentile speed.
? The established speed limit on adjacent section of the same roadway.
? The adjacent land uses along the roadway.
* The design speed of the roadway is 45 mph. However, due to roadway geometry, there are no horizontal or vertical curves limiting vehicle speeds.
* Cur...
