Appendix B
Comparable Utility Programs Reviewed
Scroll horizontally to view all columns.
| Utility | State | Administrative Topic | Primary Chapters |
|---|---|---|---|
| Irvine Ranch Water District (IRWD) | California | Resident-count water budgets; additional-occupant variance; documentation; annual renewal | 6, 7, 8, 9, 10 |
| Las Virgenes Municipal Water District (LVMWD) | California | Water-budget adjustments based on permanent-resident count; District review | 6, 7, 8, 9, 10 |
| City of Boulder | Colorado | Individualized water budgets; household-size adjustment; review and renewal mechanisms | 6, 7, 8, 9, 10 |
These programs are comparative implementation evidence. They demonstrate that resident-count adjustments can operate within conservation-oriented pricing and ordinary utility administration. They are not legal precedent for New York and do not establish Veolia-specific cost, eligibility, gallon allowances, or documentation rules.
