Glendora and La Verne Collaborate on Water Use Efficiency Dashboard Project

The Water Commission Meeting held on July 24, 2025, in Glendora, California, focused on urban water use reduction targets and the challenges of data integrity in water management. The meeting highlighted the city's objective to achieve a 20.3% reduction in urban water use for the fiscal year 2024-2025, a target that has raised questions among commissioners regarding its comparison to neighboring cities like La Verne.

Commissioners discussed the complexities of comparing water reduction targets across cities, noting that Glendora has a larger population and significantly more irrigated area than La Verne. This discrepancy complicates direct comparisons and raises concerns about the accuracy of the data being reported to the state. The meeting underscored the need for validated data, as inconsistencies in service area maps between Glendora and neighboring agencies could impact reduction targets.

A key initiative discussed was the Water Use Efficiency Dashboard Project, funded by an $84,391 grant from the U.S. Bureau of Reclamation. This project aims to enhance landscape water use efficiency through aerial imagery analysis and land use classification. The dashboard will help validate data for urban water use reporting and is a collaborative effort with the city of La Verne.

The meeting also addressed the importance of accurate data collection methods, with discussions on the use of advanced technology to assess land coverage types. While the current project does not include individual parcel water usage data, there are possibilities for future enhancements that could allow for more detailed comparisons between different types of properties.

In conclusion, the meeting emphasized the ongoing challenges in achieving water conservation goals and the importance of reliable data in shaping effective water management strategies. The next steps will involve further validation of data and continued collaboration with neighboring agencies to refine urban water use objectives.
