EXECUTIVE SUMMARY
At a Coombsville Community Meeting on June 30, 2023, several residents raised safety and line of sight related concerns at the intersection of Coombsville Road at 1st Avenue and similar concerns at 4th Avenue. Public Works staff requested the Fehr and Peers (F&P) Engineering Consulting Firm to conduct a traffic safety survey and prepare a report on Coombsville Road at the 1st Avenue and 4th Avenue intersections.
F&P's report recommends installation of stop signs for eastbound and westbound traffic on Coombsville Road at 4th Avenue to provide a three-way stop intersection due to limited line of sight for safe traffic operations (4th Avenue already has a stop sign). The report does not recommend installing stop signs on Coombsville Road at the 1st Avenue intersection because none of the state established all-way stop control warrants are met, which are based on traffic volumes (motor vehicles, pedestrians, and bicyclists), vehicular speed, collision data and line of sight. The report indicates traffic calming measures at 1st Avenue should be implemented to improve safety conditions for motor vehicles, bicyclists, and pedestrians.
The proposed Resolution will authorize installation of an all-way stop control on eastbound and westbound Coombsville Road at 4th Avenue. The Director of Public Works intends to implement traffic calming measures at Coombsville Road and 1st Avenue (no Resolution is required for that action).
