For Miller Ferry Bridge <br /> We are asking for permission to permanently mount an acoustic doppler current meter on the <br /> far south west piling at Miller Ferry Bridge on West Walnut Grove Road, approximately 4.25 <br /> miles west of 1-5. (See photo 4, point 2.) The Doppler and instrument enclosure will be <br /> mounted to the piling in a similar way to the one depicted in photo 5. It will be attached with <br /> stainless steel lag bolts. We will pre-drill the holes and fill the hole with Henry's roofing cement <br /> before installing the lag screws. The installation will be done from the water by boat and will <br /> not interfere with vehicle traffic in any way. All of the equipment will be installed so that it will <br /> not interfere with the visibility of the red light on the piling. <br /> We need a source of power but because of the red light and the bridge sign I do not see a good <br /> way to mount our usual solar panel. We have a similar situation at our instrument located on <br /> the Highway 4 Bridge where it crosses the Old River. There we were given permission to tie <br /> into the power for the red light to run our battery charger at night when the red light is on. i <br /> was hoping we could do the same here. I propose to put the 110 power and our battery <br /> charger in a water proof box so that only 12 DC would leave that box and go to our instrument <br /> enclosure where the battery is. This way in the event that our equipment gets shorted it would <br /> blow the fuse in the charger and not impact the power for the red light. <br /> We hope to install this equipment during the first week of December 2010.
