„ ,/, 4/L MEMORANDUM Memo To :Mayor and Council Members From :Ric Minetor, City Engineer/Director of Public Works Date :February 28, 1990 Subject :Stop Sign Request on Knoliwood Drive at Woodcrest Drive We have received a request from residents in the area of Knoliwood Drive between County Road H and Woodale Drive for STOP SIGNS on Knoliwood Drive at Woodcrest Drive. This would be a multi-way STOP SIGN and is regulated by state statute. The requirements are that these installations meet the "warrants” listed in the Minnesota Manual of Uniform Traffic Control Devices. The manual lists the following conditions as justifying a multi-way STOP SIGN installation: 1. Where traffic signals are warranted and urgently needed, multi-way STOP SIGNS may be used on an interim basis while arrangements are made for installing traffic signals. • 2. An accident problem, as indicated by 5 or more accidents in a 12 month period, which are susceptible to correction by the installation. 3 . Minimum traffic volumes of: a) A total from all approaches of 500 vehicles per hour for any 8 hour period, and b) The combined vehicular and pedestrian volume from the minor street must average 200 units per hour for the same 8 hours, with an average delay to vehicles on the minor street of 30 seconds, but c) When the 85th percentile approach speed of the major street exceeds 40 miles per hour, the minimum vehicular volume is 70 percent of the above requirements. These warrants are not met at this location. Therefore, my recommendation is not to install any STOP SIGNS due to the liability of unwarranted Stop Signs. The request also mentioned speed limit signs or "watch for children" signs. Speed limit signs could be installed, but there is the trade-off of posting 30 mile per hour speed limits for those over this limit versus those drivers that currently drive less than 30 m.p.h. because they are unsure of the speed limit.
