Capital Improvements

COMB's Capital Improvement Program or Infastructure Improvement Plan (IIP) is designed to address issues regarding the conveyance system and involves repair, improvement, rehabilitation or replacement as indicated by engineered evaluations, analysis, design, planning, and implementation.

The IIP provides an inventory of those assets determined to require rehabilitation over a five-year planning horizon. The IIP identifies the improvements needed in the Cachuma Project System and sets forth review criteria to enable the prioritization of projects for budgeting and scheduling improvements during the five-year period. Prepared as a guidance document and in anticipation of review by COMB Directors, the IIP serves to inform the Member Agencies served by COMB prior to presentation to the COMB Board of Directors for adoption as a component of the annual Operating Budget.
