He noted that this particular line runs parallel to the railroad tracks 14 and vibrations in the soil are believed to have contributed to a shifting in the pipe.

I -Ie indicated he was okay with the additional cost for concrete if it 38 alleviates the water run-off from St. Anthony into Minneapolis but was unsure if this was a long - 39 term fix. 40 41 City Engineer Hubmer noted that an advantage with concrete curbing is that it will have catch 42 basins in the concrete and if asphalt was used, it would require rolled asphalt curbing which will 43 not last. He added the concrete curbing will keep the water on the St. Anthony side. 44 45 Councilmember Stille requested a detailed breakdown of the funding sources and project costs at 46 the time of the public hearing on February 28"i.
