The following represents my analysis of each of the CIP projects: This is the third independent review of the District s CIP program, 1992 93 being the first year reviewed. The 1994-95 proposed improvement projects appear warranted and the report continues to properly reflect the on-going capital improvement program. Project 1112100-139 Congress Pump Station Abandonment This is the second of several projects to eliminate pump stations. Based on discussions with staff approximately 1300-feet of 12-inch sewer will be constructed. Project will abandon the existing pump station, and will include new manholes as well as revamp of several others. For budget purposes the estimated design/construction cost and contingency cost appears reasonable. It is suggested that future and similar projects include a location/vicinity map, estimated footage of pipe to be placed and other appropriate items (major). Project 112100-140 Reconstructing Various Sewer Line This project is similar to previous years projects and is in keeping with the Districts rehab and maintenance program. Previous years projects were Nos. 122, 126 & 132.
