2018 MnDOT Highway 50 Mill and Overlay

In 2018, MnDOT will be doing a mill and overlay project on Highway 50 from Highway 3 in Farmington to Highway 52 in Hampton.  The project will consist of resurfacing, sign replacements, ADA upgrades, and other miscellaneous improvements.  This project was originally scheduled for construction in 2017, however, due to a funding approval delay from the state legislature, the project was delayed.  More information regarding the project may be found on the MnDOT website.

If you have any questions related to the MnDOT Highway 50 Mill and Overlay, please contact Civil Engineer John Schmeling at 651-280-6846 or Email.

2017 Street Maintenance

The city performs annual street maintenance in selected areas of the city on about a 7 year cycle.  This maintenance is performed to extend the life of the streets.  The maintenance consists of street crack sealing and seal coating.  These maintenance strategies are performed by private contractors and administered by the Engineering Department.  The following are explanations of each maintenance strategy:

Street Crack Sealing

Asphalt streets are designed to be flexible to accommodate the freeze/thaw cycle of our climate.  Subsequently, longitudinal and transverse (thermal) cracking will occur in relatively new streets continuing throughout its life due to age, traffic, weather, etc.  To minimize the infiltration of water through these cracks, they are periodically sealed with a flexible asphalt sealant.

Street Seal Coating

Exposure to the sun leads to the degradation of streets by “baking out” of the asphalt.  To seal and rejuvenate the surface of streets the asphalt is periodically sprayed with an asphalt emulsion.  Rock is then applied to facilitate quick access and safe surface friction.  This strategy is typically preceded by a crack seal the year before.

Street crack sealing and seal coating will be taking place this summer between May 15 and August 15, 2017.  No parking signs will be posted a minimum of 24 hours prior to the start of service. No parking in these areas will be enforced by local law enforcement.

To see which streets are receiving crack sealing and/or seal coating, please refer to the 2017 Farmington Projects Map.

If you have any questions related to the street maintenance projects, please contact Engineering Technician Shawn Snyder at 651-280-6844 or Email.

2017 Trail Maintenance

The city performs annual trail maintenance in selected areas of the city on about a 5 year cycle.  This maintenance is performed to extend the life of the trails.  The maintenance consists of trail crack sealing and fog sealing.  These maintenance strategies are performed by private contractors and administered by the Engineering Department.  The following are explanations of each maintenance strategy:

Trail Crack Sealing

Asphalt trails are designed to be flexible to accommodate the freeze/thaw cycle of our climate.  Subsequently, longitudinal and transverse (thermal) cracking will occur in relatively new trails continuing throughout its life due to age, usage, weather, etc.  To minimize the infiltration of water through these cracks, they are periodically sealed with a flexible asphalt sealant.

Trail Fog Sealing

Exposure to the sun leads to the degradation of trails by “baking out” of the asphalt.  To seal and rejuvenate the surface of trails the asphalt is periodically sprayed with an asphalt emulsion and is left to dry for a period of time.  This strategy is typically either preceded or followed by a crack seal.

Trail crack sealing and fog sealing will be taking place this summer between May 15 and August 15, 2017.  Properties with driveways that have trail crossings will be notified at least 24 hours in advance of the fog seal operation.  Access to driveways that have trail crossings will not be available after the fog seal is applied and while it dries.  Depending on conditions, a dry time of at least 2 hours should be expected.

To see which trails are receiving crack sealing and fog sealing, please refer to the 2017 Farmington Projects Map.
