EE EKING fiSSOUflTES Memo TO: Honorable Mayor and City Council Members FROM: Lee Elfering, City Engineer DATE: June 17, 2011 RE: Waterworks Trail Railroad Crossing Background This memo is a follow up to the Council's request for further review and information regarding the completion of the Waterworks trail north of South Owasso. As outlined in the previous memo the current BNSF railroad crossing permit has an allowed construction timeframe of 1 -year, which would require construction of the trail this summer. This does not leave sufficient time to obtain or even explore additional funding sources to lessen the unbudgeted additional costs for completion of the trail section. Anticipated Costs The previous memo estimated a cost of $140,000 to $150,000 for completion of the trail project. Attached to this memo is a detailed Engineer's estimate of the project costs to complete the Waterworks trail north of South Owasso Blvd. The estimate has separate schedules for the completion of the work associated with the railroad crossing and those associated with modifications of the existing trail segments. Included in the railroad trail crossing is 1,136 cubic yards of granular borrow at an estimated cost of $15,904.00. This cost includes both supplying the additional fill material and grading of the material to the desired grades. There is an opportunity to eliminate a large portion of the borrow material cost this year by utilizing excess material from the Dianna Lane reconstruction project. The street Contractor would haul the material to the site, but any grading of the material would be at an additional cost. We have requested pricing for grading the material from the street Contractor but to date have not received any pricing. We would estimate the grading costs around $5,000 - $6,000 resulting in a $10,000 savings on the project. This savings could be realized again next year if the trail project were delayed, as long as the City completes a street reconstruction project as outlined in the City's Capital Improvement Plan. BNSF Railroad Crossing Permit As stated above, the BNSF crossing permit currently requires the construction of the trail crossing this construction season. We have inquired about extending the construction timeframe granted within the permit with BNSF and have been informed that the permit can be amended to allow for construction through next year. The cost to amend the permit would be $600.00. 10062 Flanders Court NE — Blaine, MN 55449 — Ph: (763) 780 -0450 Fax (763) 780 -0452 Memo - 061711 -CC (RR Trail X -ing)
