Subcut Work Finished On Loring Lane, Continues On Woodstock Ave & Yosemite Circle
Loring Lane
Crews completed the subcut of Loring Lane last week and started to bring in class 5 gravel.
A utility crew will install drain tile on the west half of Loring Lane the first part of this week. Once the west portion is finished, they will move to the east half and continue installing drain tile. Each property will receive a drain tile stub into which residents can tie their sump pump discharge hose.
Yosemite Circle
Crews will be subcutting Yosemite Circle the first part of the week. Yosemite Circle east of the West End Apartments will also be subcut this week, weather permitting.
Woodstock Ave
Most of the utility work on Woodstock has been completed. Crews will finish subcutting the area once finished with Yosemite Circle. They will start at the Turners Crossroad intersection and work their way towards Yosemite Ave N.
Perry Ave
The Perry Ave addition is scheduled for curb and gutter this week. The contractor will install class 5 on top of the sand section and grade the street. Once the class 5 is down, crews will pour the curb, weather permitting. .
Construction Terms: What Is A Subcut?
Golden Valley’s original streets were built on soils that did not provide the best foundation for roads with vehicle traffic. Therefore during reconstruction, it’s often necessary to improve the soil base beneath the roadway.
The subcut operation is a soil correction procedure that removes the poor soil beneath a roadway and replaces it with sand. The sand is spread evenly and compacted to increase density and provide extra strength for the future road.
The high permeability of sand allows better drainage than native soils, an important component in extending the life of the street. Poor drainage can cause issues such as potholes and road heaving.
Ground-up asphalt from the old road is put on top of the sand to provide a drivable surface until the curb and road are installed. The subcut is typically 3 feet below the surface of the new street.
Why Install Curb And Gutter?
Concrete curb and gutter provides superior drainage as well as a structural edge to support the roadway—two key advantages over rolled bituminous curbs or no curb at all. Moisture collecting on the street and in the street subgrade is a primary cause of premature street failure.
Concrete curb and gutter:
• collects water and transports it to storm pipes, providing superior drainage following rainfall and snowmelt. Without curb and gutter the water would run to the side of the road and either go into the subgrade or run along the boulevard.
• assists the contractor control the grade of the street to reduce the formation of low spots (“bird baths”) along the edge of the road.
• helps collect sediment from the street (eg, sand) that can later be cleaned up through routine street sweeping. Such maintenance efforts help to improve the quality of the water that runs off of the streets and into Golden Valley’s streams and ponds.
Without the structural support provided by curb and gutter, pavement distress (settlements, edge cracking, and alligator cracking) will appear along the edge of a roadway much sooner, ultimately resulting in the premature failure of the street and increased maintenance costs.
Golden Valley is committed to building and maintaining quality roads and installing curb and gutter is an essential component in extending the life of a road as long as possible and significantly reducing long-term maintenance costs.
Prioritize Construction Safety
During the construction season, the No. 1 concern for the City of Golden Valley and the contractor is the safety of both the workers and the public. This goal can only be met through everyone’s help and cooperation.
Please do all you can to keep yourself and children away from the construction work and equipment, especially over the holiday weekend. Do not let children or pets climb on or play near dirt piles, trenches, equipment, or other work areas. Should an accident occur, call 911.
