4 Executive Summary Presently, a gap exists between the Springwater on the Willamette Trail ending at SE Umatilla and the Three ridges portion of the Springwater Corridor Trail starting at SE 19th. The optimal alignment to connect the trail segments utilizes the same railroad corridor and provides a direct and seamless connection. A costalignment alternative was produced for the railroad corridor connection. The cost estimate does not include right-of-way acquisition costs or compensation for loss of future business due to the removal of sidings. Cost estimates for all intersections were developed by the Portland Office of Transportation PDOT. Recommended Alignment Green line on maps $3,090, The recommended alignment is a rail-with-trail shared-use 12 foot path on the southwest side of the mainline track from SE Umatilla to SE 13th. From SE Umatilla to SE Marion, the track is shifted to the northeast to provide space for the trail. At SE 13th, the alignment moves to the north of the mainline track for its duration. etween SE 13th and 17th, the railroad track and spur line are shifted to the south to accommodate the trail. etween SE 17th and SE 19th, the multi-use path is a 10 foot wide segment on the north side of SE Ochoco. The cost estimate does not include the sum necessary to acquire an easement through private property between 11th and 13th. Alternative Alignment Light green lines on map $3,084, An alternative is offered which incorporates trail deviations in order to minimize costs associated with moving power poles and easement acquisition. Deviations occur from SE Marion to 11th Street through Metro owned property and along 11th and Ochoco St. to avoid the acquisition of an easement on private property. In this scenario, no easement or property acquisition is required. 1
