Local let maintenance contract, trinity CO, ditch cleaning and reshaping

I cannot write a summary from this source. The government file attachment (6508-34-001_1026.txt) is referenced but its content is not provided — only a meta-note indicating the file exists. Without the actual scope, specifications, eligibility rules, contract value, timeline details, and other substantive terms from the attachment, I cannot extract the decision-relevant facts needed to lead with the issuing body, the procurement action, what is being procured, and the hard deadline.

Provide the full text of the attachment or a source document that contains the solicitation details, and I will deliver the summary.
