Freight land use clusters in northeastern Illinois

Freight is a critical component of the regional economy in northeastern Illinois and generates significant transportation demand across multiple modes. While much of the Chicago Metropolitan Agency for Planning's (CMAP) prior and ongoing work focuses on the economic and transportation aspects of freight planning, proper freight land use strategies and policies are also essential to ensuring a high-quality freight network. Freight-related land uses affect issues of regional concern, such as development patterns and the transportation system, as well as more local concerns such as mitigation of harms from incompatible land uses.

To help provide a foundation for freight land use issues, this Policy Update identifies the most significant clusters of freight-supportive land uses in metropolitan Chicago and presents key descriptive statistics regarding the land use and transportation context of those clusters. Previous CMAP Policy Updates have analyzed recent industrial development trends in the Chicago region and how those compare to trends in the rest of the country.

Identifying regional clusters

While freight activity can be generated from a variety of land uses, some are more freight-intensive than others. Moreover, these freight-intensive land uses tend to co-locate in order to take advantage of efficiencies derived from shared infrastructure and workforce. Identifying regional clusters of dense, freight-supportive land uses will help to focus future research and recommendations.

There are two ways to describe the density of freight-supportive land use: either the land area encompassed by freight-related activities, or the building stock of freight-related facilities. An area with most of its land set aside for industrial use will clearly have concerns related to freight, but so will an area with less total industrial land but many facilities generating freight traffic.

This cluster analysis assesses both the percentage of land designated for industrial use and the amount of rentable building area (RBA) classified as warehouse, manufacturing and food processing, or distribution in by CoStar, a provider of real estate data. These three subcategories of industrial facilities were judged to have the largest impact on freight movement; other industrial subcategories such as flex space were not included. The resulting individual clusters were classified based on geography, statistical profile, and a qualitative assessment of shared concerns, shown below.

Spatial analysis of land use and building stock data resulted in six regional clusters. Three of those clusters -- Core/Midway, Greater O'Hare, and South Cook -- are located near the center of the region, close to established transportation facilities and workforce. The other three -- North Chicagoland, Fox River Valley, and Will County -- lie further towards the edge of the region. These clusters contain 71 percent of the industrial land and 82 percent of freight-related building area in the region and roughly align with an initial staff assessment of trucking bottlenecks on the region's highway network.

This regional analysis is meant to identify and describe broader zones of freight-related activity, and future studies will analyze each of these clusters in greater depth. In some cases, it may be appropriate to further subdivide clusters for a more granular understanding of how to best address local routing, land use, and/or economic development issues.

Cluster statistics

Relevant statistics about these clusters can be organized into three sections: land use, RBA/buildings, and infrastructure. The cluster profiles below describe the varied makeups of these areas and highlight distinctions between the region's largest three clusters -- Greater O'Hare, Core/Midway, and Will County -- and the smaller clusters of Fox River Valley, South Cook, and North Chicagoland.

The land use statistics describe the total coverage of industrial land in each cluster. Other important considerations include the availability of that industrial land (i.e., whether it is occupied or vacant) and the size of parcels in the cluster. The latter two metrics suggest the cluster's potential for growth and its ability to adapt to demands for all kinds of industrial facilities, whether ever-larger distribution centers, or smaller, more flexible manufacturing, or warehouse spaces.

RBA statistics indicate the intensity of freight-supportive uses in a cluster, as well as describe the industrial mix. Median age and size of buildings in a cluster are also important indicators of divergent needs. Legacy areas filled with older, smaller buildings will have very different land use issues than emerging clusters with newer, larger buildings.

One of the most important infrastructure concerns for a freight cluster is access to a freight-suitable transportation network. This includes railroads, highways in the National Highway Freight Network (NHFN) as initially designated by the U.S. Department of Transportation per the Fixing America's Surface Transportation (FAST) Act, and designated state and local truck routes. Also, intermodal rail-highway facilities are increasingly key pieces in the freight transportation system, having grown in prominence as long-distance shippers continue to shift toward containerization.

Although access to water and air transportation is an important consideration for some shippers, those assets were not included in these statistical profiles due to the limited geography of air and water facilities in the region. Even without measuring this infrastructure directly, the region's major airports clearly serve as hubs of freight activity in metropolitan Chicago. CMAP has already evaluated workforce, stormwater, and land use issues in the O'Hare subregion.

Finally, these clusters house 62 percent of the region's freight and manufacturing employment. Employment totals and densities reflect the type of use – manufacturing requires more employment than warehousing or distribution might. These totals are also directly related to the total amount of rentable building area in the freight land use cluster. Access to a well-trained workforce is critical, and prior CMAP analysis has found that the region's freight and manufacturing workers tend to live in areas that are somewhat proximate to freight and manufacturing employment centers.

Brief cluster profiles

A brief review of the statistical profiles shown above can help identify the major issues facing each cluster.  With over 26 percent of the region's freight-supportive RBA in only 2.5 percent of the land, the Greater O'Hare cluster is by far the largest and densest freight cluster in metropolitan Chicago. That density stems in part from having a very high percentage of its land set aside for industrial uses, coupled with very low building vacancy and almost no land vacancy. While utilized parcels are quite large, vacant parcels are small; when combined with the cluster's low vacancy rates, this suggests that growth will likely occur via redevelopment rather than expansion. Other notable features of the cluster include a heavy concentration in warehouse uses, a very high density of truck routes, and easy access to O'Hare International Airport, the region's largest air cargo facility. This cluster contains 22 percent of the region's freight and manufacturing employment.

As the name suggests, the Core/Midway cluster is located in the center of the Chicago region, with extensive legacy infrastructure, the oldest median building age, smallest median parcel size, and highest building vacancy rate. There is some geographic variation, though, as the industrial areas near Midway Airport are relatively newer and larger than the areas to the north and east. Among all the clusters, Core/Midway has the lowest percentage of industrial land, though that land is also more intensively built out than in other clusters. Despite being home to the largest intermodal facilities in the region, it has few of the new, large distribution facilities increasingly utilized for goods movement. Instead, this cluster hosts the largest concentration of manufacturing and food processing space in the region. Core/Midway faces significant variation in planning issues, with some areas undergoing a transition to residential and commercial uses, while others seek public and private reinvestment to promote long-term industrial success.

In contrast to the older, established clusters, Will County is an emerging freight center with a median industrial building age of only twenty years. In addition to being new, industrial buildings in Will County are comparatively large, with median building RBA and parcel sizes nearly twice as large as any other cluster. It also has a strong specialization in modern distribution facilities and is home to several large and growing intermodal terminals. The Will County cluster has more total industrial land and more than twice as much vacant land as the next-largest? cluster. There is a significant geographic split in the cluster between the developed northern half, which would be the second-densest in the region, and the relatively undeveloped southern half. This cluster has the lowest employment density, likely reflecting the lesser employment needs for distribution facilities as compared to some other types of manufacturing.

The remaining three clusters have less significant footprints of industrial land and freight-supportive buildings. Descriptive statistics for the Fox River Valley cluster are average in most dimensions, and the cluster's division into multiple nodes lacks geographic coherence. Its most notable attribute is the relative paucity of truck routes and rail mileage. South Cook is the least-dense identified cluster and features relatively high vacancy rates paired with small parcels and old buildings, potentially making redevelopment of existing industrial land a challenge. It does, however, have access to an extensive network of rail and truck infrastructure, as well as much of the region's water cargo system. Lastly, North Chicagoland is a very small cluster notable for its high industrial land vacancy and heavy concentration in advanced manufacturing and food processing.

Looking ahead

GO TO 2040 emphasizes the need to plan for land use, transportation, and economic development comprehensively. Understanding freight-supportive land uses can help identify freight transportation needs. This research establishes a baseline understanding of the key freight land use clusters in the region. Staff intends to work with stakeholders to refine these clusters, with an eye toward developing evaluations of the most pressing opportunities and challenges facing each cluster. These findings will help the Regional Freight Plan make specific recommendations on potential topics for inclusion in detailed local freight plans, along with policy recommendations for best practices in freight land use preservation and conflict mitigation.

The areas identified in this Policy Update strongly support our region's economic success, employing the preponderance of our freight and manufacturing workers. This analysis supplements our understanding of where these workers are most concentrated, contributing to our understanding of the region's land use and economy as we develop more specific recommendations for ON TO 2050.
