Warrenville presents LiDAR‑based tree canopy data and FY26 sustainability highlights
Summary
Staff reported Warrenville's tree canopy at about 36% based on 2022 DuPage County LiDAR; FY25 tree investments were about $216,000 and FY26 about $140,000. The city also summarized fleet biodiesel/hybrid use, water conservation recognitions, and waste‑reduction efforts.
Warrenville — Asset Management Analyst Hernandez Galvin briefed the council on the city’s parkway tree management program and FY26 sustainability highlights on July 6.
Using LiDAR data supplied by DuPage County and mapping tools (ViewWorks), staff estimated Warrenville’s tree canopy at roughly 36%, above the Chicago Region Trees Initiative’s 30% benchmark. Hernandez Galvin said the LiDAR‑informed dashboard helps target plantings to where canopy gains would be greatest and allows staff to track inspections, trimmings, removals and plantings in a centralized system.
Staff reported total investment in tree initiatives during FY25 at about $216,000 (a year that included a larger grant‑funded planting push) and about $140,000 in FY26. Hernandez Galvin said FY25 work included roughly 176 newly planted trees; FY26 plantings were smaller (about 47 trees recorded in the year’s sustainability summary). The city will continue to use the data to prioritize future planting and maintenance work.
The FY26 sustainability highlights also noted operational measures: continued use of B20 biodiesel, expansion of the hybrid police fleet, water‑conservation outreach (the city received gold‑level recognition for water ambassador work), LED lighting retrofits and an upcoming solar project at Well Site 13. The police department’s annual shredding event collected 5,540 pounds of material and the prescription‑drug drop box accepted 858 pounds for the fiscal year.
The presentation was informational and no action was requested.
