Memorandum
To: Mayor and City Council
Justin Miller, City Administrator
From: Paul Oehme, Public Works Director
Date: February 24, 2020
Subject: Pavement Management System Review
Staff will discuss the current pavement management program and review the current pavement CIP
Projects. We are also recommending some changes to the current pavement project plan.
Pavement management is a systematic process of maintaining, upgrading and operating a network of
pavements to optimize pavement life and economic pavement conditions over the entire network
within an agency's budgetary constraints. The City currently maintains 311 miles of streets with an
estimated value of $366,100,000. Pavements are the largest capital asset the City maintains. It is
important to have a good pavement management system for a cost-effective program.
The City’s current pavement management program started in 2009. Approximately 25% of local
public streets and collector roads are inspected each year and rated based on general surface overall
condition and a value is assigned to each pavement segment as an overall condition index (OCI). The
rating scale is 100 for new streets to 0 for completely deteriorated streets. OCI ratings assist in
identifying areas for reconstruction or rehabilitation and when these improvements should take
place. The City’s OCI goal is to have a 75 OCI rating for an average network rating.
Lakeville's current pavement management plan is generally addressing the worst condition streets
first. This is not always the best cost-effective approach. Fewer miles are getting done spending large
amounts of money reconstructing poor pavements and allowing streets in fair condition to
deteriorate. More miles can be overlaid for the same amount of City funds with roads that are in fair
condition. This approach typically provides better customer service since pavements are not allowed
to deteriorate to a poor condition.
Staff would like the City Council to consider funding a pavement preservation treatment program and
increasing the miscellaneous project budget to mill and overlay more miles of streets annually. The
powerpoint presentation is attached to this background.
