MEMORANDUM Date: February 27, 1996 To: Mike Mornson, City Manager From: Larry Hamer, Director of Public Works Re: Silver Lane and Silver Lake Terrace Water Break The City experienced three water breaks in the 4" water line that services Silver Lake Terrace. The water break was so bad that the City backhoe could not reach the pipe that needed repair. A cave-in of ground material which was caused by a water break on the 4" line on Silver Lane destroyed the pipe on Silver Lake Terrace. We stabilized the ground and replaced 74' out of 91' of cast iron pipe. • The cost of material, equipment, labor (not counting City equipment and labor) was approximately $15,933.00. The water breaks caused hardship for the residents on Silver Lake Terrace. The line should be replaced the full length of Silver Lake Terrace with 4" ductal iron pipe with a 4" hydrant at the end. We need an engineered drawing to submit to the State Health Department. The line could be replaced by the Public Works Department or a contractor. We may have to have a large machine dig the excavation. If it is decided to contract out the job the Public Works Department could put the road back. In any case I recommend that we put the road back. It is estimated that the watermain replacement is about $23,100.00 for labor and equipment and $5332.00 for the watermain. I recommend that we replace the watermain with the City removing the asphalt for the contractor and replacing the asphalt road with budget money.
