Budget estimate

$500,000 – $2,000,000

The budget for this contract is estimated to be between $500,000 and $2,000,000 per year, based on the scope of work and the requirements for insurance and bonding. The County reserves the right to award a contract to one or multiple firms, and the selected firms will be required to provide a cost proposal, including unit prices for all items.

However, the actual budget will depend on the specific services provided and the rates negotiated with the selected firms.
