Street Maintenance, McFarlen, MN To report problems with street maintenance please call the pubic works department at 341-472-3680 during our normal office hours: 7:00 a.m. -4:00 p.m. After hours, please leave a message on the Public Works Hotline at 341-472-3600, or e-mail the public works department at maintenance@mcfarlendpw.gov. In case of an emergency, please contact the McFarlen Police Department at 341-472-3000. If you notice any of the following, please report the problem: Potholes, street asphalt, guardrails, or reflective markers on City-maintained streets need to be repaired or replaced. This excludes areas where road maintenance is in progress. Street traffic signs need to be repaired or replaced Pavement marking needs repair (e.g., yellow lines between lanes) Parking meters are knocked down or not working Streets are flooded due to storms Spill response is needed Graffiti is found To: maintenance@mcfarlendpw.gov From: Becky Price Date: January 23, 20- Subject: Stop sign down To Whom It May Concern: I am writing to let you know that there is a stop sign down, at the corner of Cherry Street and Tenth Avenue. It must have fallen down during the storm last night. I'm concerned because this is a residential area that borders the high school property. The corner gets a lot of traffic, especially when school is in session, and I believe it could be dangerous without a stop sign. Normally, Cherry and Tenth is a four-way-stop intersection. As you can no doubt imagine, without the stop sign, the possibility for accidents is high. If you would like to contact me, please feel free to do so: 742-488-3126. Thanks, Becky Price When does the department of public works open?
