This document appears to be from a presentation discussing options for a wastewater treatment facility project. It outlines two scenarios for Navy participation that impact costs, presents timelines and milestones, and analyzes the estimated rate impacts on users under different funding scenarios where the total project costs range from $70-93.5 million. Phasing and timing of the project would depend on city growth and Navy participation.
