Chanhassen outlines strategy for maintaining 119 miles of city streets
The Chanhassen City Council discussed its Pavement Management Plan on Friday, detailing how the city will maintain and repair its extensive street network using a systematic approach that evaluates road conditions and prioritizes improvements.
The City of Chanhassen is responsible for maintaining approximately 119 miles of streets, a significant infrastructure challenge that requires careful planning and prioritization. To manage this task, the city has developed a comprehensive Pavement Management Plan that guides decisions about which roads to repair and when.
The plan relies on a rating system called the Overall Condition Index, or OCI, which scores roads on a scale of 0 to 100 based on their current condition. The city reviews and updates these scores every three years to track how streets are deteriorating over time. This data-driven approach allows city officials to focus limited repair budgets on roads that need attention most urgently.
One key technique discussed is called "mill and overlay," a repair method designed for roads that show surface wear but still have a solid foundation underneath. These roads typically score between 60 and 80 on the OCI scale. The mill and overlay process removes the top layer of pavement and replaces it with fresh asphalt, extending a road's useful life by 15 to 20 years. This approach is more cost-effective than complete reconstruction for roads that aren't yet in critical condition.
By using the Pavement Management Plan, Chanhassen can strategically schedule construction projects, allocate funding efficiently, and communicate clearly with residents about which streets will be improved and when. The plan balances the city's need to maintain safe, drivable roads with the reality of limited municipal budgets.

[0:00] the city of Chanhasson manages
[0:02] approximately 119 miles of streets in
[0:04] their upkeep We review and grade
[0:06] sections every 3 years Based on funding
[0:08] we prioritize what roads need work and
[0:11] schedule construction and repairs This
[0:14] is our pavement management
[0:17] plan One technique the city uses to
[0:19] rehabilitate our streets is a procedure
[0:21] called mill and overlay Mill and overlay
[0:23] is a road construction technique that
[0:25] involves grinding off that top layer of
[0:27] a road surface and installing a new top
[0:29] layer of pavement This is a structural
[0:31] improvement that extends a road's life
[0:33] cycle We use this construction technique
[0:36] when a road starts showing signs of
[0:37] deterioration and scores somewhere
[0:39] between the 60 to 80 range on the
[0:41] overall condition index A 100point scale
[0:43] we use to rate a road's health Although
[0:45] we use the OCI to address road
[0:47] rehabilitation keep in mind that other
[0:49] engineering factors may play a role in
[0:51] the selection process For more
[0:53] information on the selection process
[0:54] make sure to check out the first video
[0:56] in our pavement management series Those
[0:58] ranges indicate that the pavement is
[0:59] starting to show signs of distress such
[1:01] as cracking but the underlying aggregate
[1:04] base and sub layer are still in good
[1:06] condition The lower the score the deeper
[1:08] we have to mill and the more that we
[1:10] have to take off the top Regardless of
[1:13] how much is mil just replacing that top
[1:15] layer alone saves a ton of cash and
[1:17] gives the road an approximate 15 to 20
[1:20] year boost in life expectancy That's
[1:22] milling overlay a road construction
[1:24] technique that replaces the top layer of
[1:26] the road and extends its life cycle For
[1:28] more information about why we choose
[1:30] certain repair methods over others an
[1:31] overview of the construction process and
[1:33] more intensive construction techniques
