LASSOCIATES, IN Consulting Engineers —Land Surveyors September 5, 1989 CITY COUNCIL CITY OF LITTLE CANADA 515 East Little Canada Road Little Canada, MN 55115 RE: PAYNE AVENUE Dear Councilmembers: 500 West Highway 96 St. Paul, Minnesota 55126 484-3301 Pursuant to the council meeting of August 9, 1989, we have researched our files as well as those we can find in the City Hall relative to Payne Avenue. In reviewing these records and letters, we have formed a recollection of events which have until now been largely forgotten or at least overlooked. We will attempt to reply to the questions raised at the August 9th meeting based on the minutes of said meeting. At the same time we will lay out a chronology of events as pieced together from the records. Payne Avenue was first discussed in 1974. It was tabled from time to time until a majority of the owners could agree. The decision to order the improvement was made in 1978. Plans were drawn and bids taken. The project was completed in 1979. The project consisted of construction of sanitary sewer, watermain, storm sewer and bituminous street. This was the first street in the City to have concrete curb. Although the soils were a concern at the time, the greatest concern was the water table. With this in mind, soil borings were taken to determine conditions at depths of 10 to 12 feet insofar as sewer and watermain construction was feasible. Construction of sanitary sewer and watermain necessitated the complete excavation of the street to an average depth of eight to 10 feet. The borings were taken to determine the water level and any special construction technique that might be required such as dewatering. Consequently borings of the type taken in 1986 and 1988 simply do not exist. Even if they did, they would be meaningless since virtually the entire street was excavated, backfilled and a fill of 30 inches of sand gravel was placed over the street. The soil conditions were, therefore, quite different after the utilities were built than before. Page 64
