Harnessing Advanced GIS Data for Smarter Infrastructure in Rural and Suburban Counties

Key Takeaways

Winnebago County utilized federal grants to enhance its infrastructure data collection and management.
Advanced technologies like lidar have dramatically improved efficiency and accuracy in asset management.
The initiative allows for proactive maintenance, saving time and budget through informed planning.

Funding for Infrastructure Modernization

Cook County, the most populous in Illinois, oversees extensive infrastructure, including over 1,620 lane miles and numerous traffic signals. By contrast, Winnebago County operates on a smaller scale with 300 lane miles and constrained resources. This disparity highlights the need for effective asset management, particularly among counties lacking the budget for advanced technology.

Recognizing this challenge, Winnebago County shifted focus to grant opportunities that could fund asset modernization. Programs like Illinois’ Statewide Planning and Research Program (SPR) provide state and federal funds specifically for data collection and asset management. Securing a grant from SPR enabled Winnebago County to partner with NV5, facilitating the acquisition of lidar and high-resolution imaging data, which were previously unaffordable.

Impact of Geospatial Data

Given limited resources, Winnebago County could only gather necessary data during employee downtimes. This grant allowed NV5 to complete extensive surveys that would have taken the county’s staff decades to finish. The data collected included detailed features like driveway lines and stormwater catch basins, boasting a precision of 5 to 20 centimeters. Over 90% of this data was new and transformed into a modern digital format, significantly enhancing the county’s asset management capabilities.

The key benefits of this data were immediate. Time savings and increased efficiency were realized, with the ability to create accurate ground models quickly. By transitioning to this advanced method, savings of over 50% compared to traditional surveying techniques are projected.

Proactive Asset Management

Access to accurate data has transformed asset management in Winnebago County. A comprehensive inventory of street signs now enables compliance with Federal Highway Administration standards, moving away from reliance on public feedback for maintenance. Similarly, precise information on culverts and storm sewers allows for more accurate budgeting for maintenance prior to issues escalating.

Looking ahead, Winnebago County plans to leverage this wealth of data for future engineering projects, aiding in planning and execution, particularly for roadway improvements and storm sewer mapping. Enhanced GIS capabilities will facilitate complex queries, improving decision-making processes.

In conclusion, Winnebago County’s experience demonstrates that with strategic grants and partnerships, even smaller counties can utilize advanced technology to significantly improve infrastructure management and planning for the future.
