The District updates on a regular basis its Water Master Plan and Wastewater Master Plans. These Master Plans are based on the best known information at the time they were prepared considering proposed development within the District’s Boundary and Area of Influence which are areas proposed to be annexed to be within the District. These Master Plans represent the Capital Improvement Projects (CIP) and their value in 2021 dollars in order for the District to meet system demand for water and sewer capacity to complete system build out. Values shown will be adjusted based on the Engineering News Record Construction Cost Index for the Los Angeles Area on an annual basis. These CIP costs are used to determine Connection and Capacity Fees for new construction projects to join into the District’s Water and Sewer Systems.”
