The city makes supplements to the budget every year to accommodate for increases in expenses or revenue which weren't anticipated before the original document was adopted.
Several large projects which are included in the supplement are the result of grant revenue. The City of Hermiston regularly does not budget for anticipated grant revenue until it is actually awarded. Several supplements had to be made to cover the costs of the Oxbow Trail project, which received $135,000 in State of Oregon grant revenue and $20,000 in donations. The FAA also awarded a $270,000 grant to the city for its fencing project at the airport.
The full list of budget supplements can be viewed on the City's website as a report under the March 24 City Council agenda.
