<br />City of CentalVllle <br />IF Trail Grant <br /> <br />Page 2 <br />4/15/09 <br /> <br />BrIdge DesIgn <br />With the change In I'OIJll! for Segment l, the bridge we had designed was eQminated. like the <br />trail segment, most of the bridge design and associated hydraulic analysis had been completed. <br />The new I'OIJll! necesslIates the extension of two large culverts under Brian Drtve. These culwrts <br />are large enough to be classified as a bridge. The extension of these culverts will need to be <br />designed and approved by a bridge engineer. Additionally, the extension of the culwrts will <br />necessitate hydraulic modeling to show that II: will not affect the flood elevations upstream. This <br />work Is beyond the scope of our original proposal. A aedit will be given for the final design work <br />not completed on the original bridge. <br /> <br />Permits <br />The change In I'OIJll! for Segment L will necessitab:: changes to our permit applications to RIa! <br />Creek Watershed DIsb1ct both for storm water treatment as well as wetland impacts. Addlliomllly <br />we must now mltiga~ for fill placed in the fIoodway around the culverts. This work Is beyond <br />the scope of our original proposal. <br /> <br />Coordination of Agency RevI_ SUbmittals <br />The change to Segment L will need to be reviewed by MNDOT, but should not represent much <br />additional alOI'dination. Unless MNDOT requests additional infonnation to justify the change, we <br />do not see any of this work as beyond our original scope. <br /> <br />Easements/R.O.W. DeII!lrmlnatlon <br />To this point, aty staff has done its best to handle easement acquisition. We now have a refined <br />design and are ready to begin creating specific and exact easement descriptions. For this task, <br />staff will likely require our assistance, including drafting figures, calculating areas and writing <br />legal descriptions. Easements are needed for about 15 parcels. Additionally, a certifIca~ of <br />survey Is needed for two properties along the lake adjacent to the proposed trail-side park. <br /> <br />Some segments of the trails go through unplatted areas where the exact location of property <br />tines is not immediately available electronically. Given the federal requirements for the width of <br />trails and setbacks from roadways, we are ~ within a foot or two of locating a traU into <br />existing right-m-ways. Therefore, we must determine the precise locations of these property <br />Qnes. <br /> <br />This work Is beyond the scope of our original proposal as no land surveying work was Included in <br />the original proposal. <br /> <br />35 <br />
