Title

Resolution to Increase a Best Source Purchase Order with Liquid Calcium Chloride Sales, Inc. for Roadway Calcium Chloride ($30,000.00 Increase, Total Purchase $54,971.86)

Memorandum

Attached for approval is a resolution authorizing an increase to the Best Source purchase order with Liquid Calcium Chloride Sales, Inc. for roadway surface treatment materials related to the Public Works operations in FY26.

 

Liquid calcium chloride is used as a dust suppressant on gravel roads and is applied generally three times per year between spring and fall. Additional spot treatments are conducted as needed contingent upon seasonal weather. Liquid calcium chloride is also used during winter maintenance operations as a deicer for roadway surfaces.

 

Public Works has historically been able to provide these treatments for less than $25,000.000 annually, yet recent changes have led to a projected increase in the use of liquid calcium chloride.

 

Gravel roadway maintenance is a variable task based upon seasonal changes and remains challenging to predict as a result. Public Works continues to provide gravel road maintenance when dry roadway conditions permit optimal liquid calcium chloride applications. Winter maintenance pavement surface treatments vary based upon seasonal climate variations in a similar manner.

 

Additionally, newly purchased Public Works trucks have been equipped with larger liquid tanks in comparison to the outgoing trucks they replaced. The additional capacity will provide increased application rates for improved precision of surface treatment during winter maintenance operations.

 

Public Works is requesting an increase to the liquid calcium chloride purchasing ability as a result of the operational changes as well as the incidental inflationary cost increases that have historically been absorbed in the former funding requests.

 

A prior best source purchase order was approved in an amount of $24,971.86. Public Works is seeking an increase in the purchase order to $54,971.86 to provide the ability to purchase additional liquid calcium chloride for FY26. The Charter language requires best source goods procurement over $25,000.00 receive City Council Approval.

 

Liquid Calcium Chloride Sales, Inc. complies with the requirements of the City’s Conflict of Interest, Living Wage, and Non-Discrimination ordinances.

 

Budget/Fiscal Impact: Funding is available in the approved FY26 Major and Local Streets Operations and Maintenance budgets. Costs will be charged as appropriate.

 

Charter language requires best source goods procurement over $25,000.00 receive City Council Approval.
