Horstkotte, Jr., General Manager -Chief Engineer SUBJECT: REPAIR PROJECT ON THOMPSON ROAD AND GLEN ROAD, LAFAYETTE 1. PROBLEM: On September 6, 1973, the Steinbach residence at 1067 Glen Road was flooded. The cause was determined to be a stoppage in the main line due to an accumulation of grease and papers. 2. BACKGROUND: Twenty years ago, the Steinbach residence was flooded due to a stoppage in the main line, A claim for approximately $145 was paid by the District. No backwater prevention device was installed at that time. Subsequently, other minor backups have occurred including flooding of the house at 1071 Glen Road. Some corrective work has been done on the main lines at the intersection of Glen and Thompson Roads and south of that intersection. A backwater overflow device was installed on the side sewer at 1067 Glen Road on September 7, 1973, by District forces. A field investigation of the existing main lines from M26 to M16 as shown on the attached map has been performed. The line is six inches in diameter and a portion of it is flat. There are a few protruding side sewers and at lease two bad joints. 3. ALTERNATIVES: (1) Perform minor corrective work at isolated locations. (2) Install a complete parallel system. 4. RECOMMENDATION: Due to the nature of the problem, it is recommended that a new eight inch diameter line be installed from M26 to M16. The existing six inch line will be kept in service for bypassing and extra capacity. Respectfully submitted, Robert H. Hinkson Manager, Maintenance Department Recommendation approved: W. C.

The contractor has asked for an extension of time due to the excessive rains in 1972-73; delay in delivering package pump station; rejection of the electrical wiring within the package pump station by Contra Costa County Industrial Electrical Inspection Department; Pacific -Gas and Electric late schedule of power service to the pump station, etc. It has been the District policy not to allow any extension of time until the project has been completed. The pump station was finally put in operation on September 13, 1973. District personnel are now maintaining the station. The contractor has approximately 300-feet of 8-inch line to be installed plus final cleanup to complete the project. We expect the project to be completed by October 15. 3.

Horstkotte, Jr., General Manager -Chief Engineer SUBJECT: Claim of $150.00 from Mrs. Grace Steele. 1. PROBLEM: Mrs. Grace Steele claims that District forces damaged her fence at 417 Kingsley Court, Pleasant Hill. 2. BACKGROUND: An existing rodding inlet located next to Mrs. Steele's fence was repaired by District forces. The work was performed carefully and no damage was done to the fence. The fence is in a bad state of repair. It is leaning due to pressure from an earth bank next to it. It was noted prior to starting work on the inlet that a vehicle had struck the fence dislodging some boards. As a courtesy to Mrs. Steele, these boards were renailed when work on the rodding inlet was completed. 3. RECOMMENDATION: Deny the claim as no damage was done to the fence by District forces.
