C. CAPITAL IMPROVEMF2qTS PLAN
A Capital Improvements Plan (CIP) for both water and wastewater system
improvements will be developed based on the approved land use assumptions and
population projections together with the results of the Water System Study and
Wastewater Master Plan. This plan must provide for construction to commence
within two years and to have service available within five years. The CIP will
contain specific enumeration of the following items:
1. A description of the existing capital improvements within the service area and the
costs to upgrade, update, improve, expand, or replace the system components to
meet existing needs and usage and stricter safety, efficiency, environmental,
