City of Mounds View Staff Report Highway 10 Pedestrian Bridge February 24, 1997 Page 5 by the utility companies as is required by the permit they have to be in MnDOT right-of-way. The cost of signal modifications are expected to be much less and may be paid in part from grant funds. We are now estimating the projected cost at$30,000 to $35,000 less with this new information as follows: Amount/Responsible Agency Costs C Others Bridge Construction $120,000 $480,000 Design&Inspection $65,000 Easements $ 10,000(1) Landscaping $ ? Design work on drainage pond alternatives $ 7,600 Improvements to drainage pond $ 33,900 Utility modifications,undergrounding $ 30,000 Traffic signal modifications $ 5,000 $ 5,000 Contingency $ 5,000 $246,500 $515,000 (1) This is an estimate of what the fmal amount might be. Expenditures to date have been$5827.50. The primary reason for the project budget being greater than the $190,000 anticipated has been the drainage pond; $51,500 of the additional $56,500 is attributable to dealing with this item. Without that expense, the City is within$5,000 of the original obligation of$190,000 and $5,000 of that budget was contingency. The landscaping costs could be covered by directing, to this project, a portion of the money spent on landscaping throughout the city each year. We also learned from MnDOT that if there are unanticipated additional expenses which occur in the field which occur during construction,they will be covered by the grant and the local share at the same split as is in the contract award. So if the bridge bids come in below or at$600,000,then the split on any additions will be 80% federal and 20% local. The City does not have total exposure for these additional costs. Impact of Bridge • What will be the effect of"funneling" children into the shopping centers along Highway 10 north of Long Lake Road? • Will the bridge present a false sense of security and safety for people using it? • Was a professional engineer's opinion obtained as to the advisability of placing a pedestrian bridge over an uncontrolled highway? • What do we know about the demographics of the community, and how they relate to expected usage of the bridge? • Will maintenance costs go up with the addition of the bridge? • What has been the history of vehicular, bicycle and pedestrian accidents on Highway 10 Funneling children: Staff feels that bridge would not funnel children to the shopping centers any more or less than the road and sidewalk systems do from the residential neighborhoods surrounding these shopping centers. If children are now going to the shopping centers on their
