I suspect the design is conservative and <br />perhaps a little overkill for a trail bridge. <br />However, we paid for a professional recommendation and considering the amount of erosion <br />we are seeing, and the controversy we've seen to date we should follow it. Go ahead with <br />the pile foundation and let us get this thing finished. We will cover any project <br />shortages from our general fund operations budget. <br />(Kurt, I don't know if you will become involved in this topic again, but this information <br />gives support to the lower alignment.) - Johnny <br />-----Original Message----- <br />From: RICHARDSON Philip S <br />To: MEDLIN Johnny R <br />Cc: RINER Andrea G <br />Sent: 9/1/2004 6:01 PM <br />Subject: Amazon Headwaters Trail - 3rd bridge <br />Importance: High <br />Hi Johnny, <br />I have Gunnar's report back and have read through it. Gunnar is the GeoTech consultant we <br />hired to examine the conditions and provide a recommendation about the best place to <br />locate the trail and bridge between the BPA easement and Canyon Drive. I have a copy of <br />the report if you'd like to read it. Basically he says that a trail on the side slope <br />wouldn't be as stable as a trail along the flatter bottom, with the additional bridge. Of <br />the bridge locations, he feels that the middle one is best, but recommends using pile <br />foundations at least 10' deeper than the creek bottom, and preferably all the way down to <br />bedrock. He was surprised by the depth of soil in the area, which is 23.5' on one side and <br />31' on the other. The estimated cost of installing the four piles to bedrock for a bridge <br />foundation will be somewhere in the vicinity of 8,000 to 10,000 dollars. This would be in <br />addition to the cost of the bridge materials. <br />Even though our agreement with SEN was for them to install the bridge, with us supplying <br />all the materials, it doesn't seem quite fair to ask them to pay for a pile foundation <br />when we aren't using them on the two upstream bridges. I need to know if you approve <br />using city funds to install the piles - I'm certain we don't have ridgeline bond funds <br />available for this. Also, we're really cutting this project close to the grant deadline in <br />December, and I don't think we can afford to delay the bidding any further. Since this <br />bridge is a part of the trail, we can't separate out the pile driving into a separate no- <br />bid contract and would have to go through the regular public bidding process. <br />Let me know if you have any other questions. <br />Philip Richardson <br />Landscape Architect <br />City of Eugene Parks and Open Space Division <br />1820 Roosvelt Blvd <br />1 <br />
