Cnnncilmember Helmbrecht moved to direct Staff to reassess the Seivert Property with the same options as 6994 Centerville Road and to execute a letter as soon as possible to the property owner. Councilmember Brenner seconded the motion. Motion carried unanimously. 20th Avenue Forcemain Update Mr. Bergem updated the Council on the 20th Avenue Forcemain and its construction. Currently, Bonine Excavating continues to make progress on the 20th Avenue project and to utility installation. However, a determination needs to be made regarding where the final segment of the forcemain is to located. This issue is complicated by the potential development of the Lake Area Utilities parcel (Center Villa Plat). There are four options for the location of this forcemain. Each of the option, is summarized below. * The forcemain could run through the proposed Center Villa plat (center of Lake Area property) This is an optimal choice, but the timing does not work well as the plat has not been approved and is currently on hold. This would be a cost to the Developer if the plat were approved. This option is at a cost of $39,500. * The forcemain could extend north along 20th Avenue to an existing sanitary sewer manhole at the southwest corner of the Industrial Park. Temporary construction easements would be required from adjacent properties and the link would be temporary. The existing line along the Industrial Park is eight inches, which is insufficient for full development of the area served by the forcemain. Eventually, a hook up to the 12 -inch sewer in Brian Drive will be required. The cost would need to be determined at a later date. This option is at a cost of $32,500. * The forcemain could be installed as shown in the plans for the 20th Avenue Sanitary Sewer and Watermain Improvements. This is along the north property line of Lake Area Utilities. This alignment works well except for the row of trees would need to be removed in order to install the forcemain using open cut methods. This option is at a cost of $35,500. * The last construction option is a directional bore along the north line of the Lake Area Utilities. This option is more expensive than installing it through open cut methods. The cost for this option, bid as an alternate for the 20th Avenue Sanitary Sewer and Watermain Improvement project, would be hight than the other options. However, this option would allow the trees to remain along the property line. This option is at a cost of $48,390. Mr. March favored the possibility of running a 10" pipe parallel with the 8" pipe line from the lift station, north along 20th Avenue. Mr. Terry Mauer (H.R. Green Consulting Engineers) commented it is difficult to plan for vacant industrial land. Basically, textbook numbers are used to assist in developing the utilities for vacant land. 5
