SUMMARY 
The Airport has two existing snow removal contracts. On November 9, 2021, Commission
approved an increased contract value for these existing contracts by $1,200,000, to a new contract
value of $4,000,000. 
In preparation for the December 2021 snow event Port staff became aware that one of our snow
removal contractors was in a labor dispute with one of their unions, which had the potential to
impact Airport operations. 
Due to concerns of having proper resources for snow removal to ensure Airport operations, Port
staff issued two emergency snow contracts via policy waiver. Staff are now returning to ratify the

expenditures incurred. Two emergency snow contracts were issued due to resource limitations on
the part of contractors. A single contractor could not provide the services, equipment, and operators
required to meet the needs of the Airport for snow removal. 
We are requesting ratification of the two new contracts and amending one of our previously
authorized contractor's (Ceccanti) costs for the equipment and operator resources they provided
above their contract requirements. The extension of the emergency snow removal contracts is
being requested to ensure the Airport has the necessary snow removal capacity should another
winter event take place. These emergency contracts would only be needed if the labor dispute is
not resolved with our previously authorized contractor. 
We are still waiting to receive invoices from our snow removal contractors, below are the estimated
costs for the December snow events for all three contractors.

ANNUAL BUDGET STATUS AND SOURCE OF FUNDS 
While the airport is always prepared to deal with a snow event, the airport has not budgeted for
snow event costs for many years due to the variability. Over the past five years, the annual cost
of snow events (contracted services, de-icing chemicals, staff overtime, etc.) has averaged $1.7

million, with a high of $3.6 million in 2019 and a low of $113 thousand in 2018. For the most
recent snow event in December 2021, we spent an estimated amount of $1.2 million on contracted
snow removal services. So far, the airport has been able to absorb snow event costs within the
approved budget. Excluding these costs from the budget has been part of a strategy to tighten the
budget by eliminating contingency funds. Most snow event costs are included in the airline rate
bases, and any excess costs are recovered through the annual settlement. Given the desire to
manage airline costs through the recovery period, staff did not add snow event costs to the 2022
budget. Still, given the recent history of more regular snow events, staff will revisit the budget
strategy for the 2023 budget, and may recommend inclusion of some amount. The funding source
will be the Airport Development Fund.
