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 /> <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 /> <br />
