Questions about this bond
Does this cover general construction performance?
Its focus is the erosion-control obligation. Use a separate contract performance bond when a construction contract requires one.
Who sets the amount?
Use the security amount required for the county project. Have its calculation or written request ready so the application identifies the correct site and obligation.
Is an assignment of funds the same document?
No. The county publishes an assignment-of-funds alternative. A surety bond and pledged bank funds are different security instruments.
When can the security be released?
Follow the county's inspection and release instructions. Keep required controls maintained until the county releases the obligation.
