ARDEN HILLS ClTY COUNCIL - MAY 10, 1999 11 would be no private land acquisition. Mr. Brown stated that the intent was to avoid private land . acquisition as it would bc hard to justify the acquisition of improved property. Mayor Probst asked that when the map is updated, references be made in the text and graphic to thc existing grit chambers. Councilmember Larson noted that staffs recommendation is that the Council accept the Drainage Survey and Report and direct staffto begin preparing plans and specifications for the 1999 Drainage Improvement Project. He asked if staff had determined what projects would be included in the 1999 project. Mr. Brown stated that the first two projects to be proposed would be McClung Drive and Siems Court. With regard to the Siems Court project, staff is waiting to see how the street grading turns out and this project is directly connected to the street improvement projects. The McClung Drive project is a stand-alone. Councilmcmber Larson asked, ifthe Siems Court project does not move forward this year, would the the Karth Lake project take its place. Mr. Brown stated that this would be a logical step and noted that thc Karth Lake project was another stand-alone project.

The motion carried unanimously (5-0). . E. Purchase of Sewer Maintenance Machine Mr. Stafford explained that the City currently has the capability to clean sewer lines, however it does not have tlle means to remove the sludge and debris from the sewer manholes. Currently, Public Works employees insert a shop-made screen in the downstream manhole while cleaning the lines. This screen collects sand and debris that is then removed by hand. Beyond the physical demands of this type of work, OSHA classifies any entry into a manhole or lift station as a confincd space entry. To legally perform this entry, the following steps must be taken: . Confined space entry permit must be filled out . Air quality tests must be continuously performed . Blowers must be provided to circulate fresh air . An additional spotter person must be present while any worker occupies a confined space The truck mounted vacuum machine is designed to vacuum sludge and debris from sewer manholes as lines are cleaned, thus eliminating most personnel entries into a confined space area. ~ Mr. Stafford indicated that here are other uses for the sewer vacuum machine as well. During water main, sewer main and forcc main repairs, other cities use their vacuum machines to draw the saturated soils away from the area to be repaired. This allows the dry soils to be returned and compacted in the repair excavation. When all the soils are excavated with a backhoe, often the entire excavation is hauled away and replaced with dry, compactable material.
