The City’s street maintenance process is influenced by the amount of funding the department receives and ratings produced through Infrastructure Management Services software. In terms of funding, there are four ways that the City funds street maintenance. This includes grants, TIF funds, local gas tax, and the State Motor Fuel Tax of 1990. Unfortunately a majority of that funding, including grants and TIF funds are beginning to decrease. Due to limited funding, the City must direct funds in a strategic way to ensure the best quality roads the City of DeKalb can provide.

                For that reason, the City utilizes software called Infrastructure Management Services (IMS). IMS provides each street with a pavement index number that allows the City to understand the condition of the roads.  Streets with an IMS rating from 0 to 59 are red, need immediate attention, and are failing. Streets with an IMS rating from 60-79 are yellow, and indicate that the streets need maintenance to prevent them from deteriorating to the failing, red condition. An IMS rating above 80 means the street is green, and indicates the street is in an acceptable condition. The pie chart below shows how the Streets in DeKalb are performing currently. The average IMS rating for roads in DeKalb is 78.

From this information, the City can direct maintenance to focus on the pre-failing and satisfactory IMS level streets in order to prevent them from reaching the failing stage. It is for that reason that you may see one road being fixed and not the other. For more information on the City’s Street Maintenance process, please refer to the document link here.
