For New Hope Bridge <br /> We are asking for permission to permanently mount an acoustic doppler current meter on the <br /> south east piling at New Hope Bridge on West Walnut Grove Road, approximately 3.25 miles <br /> west of 1-5. (See photo 1, point 1.) The Doppler will be mounted to the piling in a similar way <br /> to the one depicted in photo 2. It will be attached with % stainless steel lag bolts. We will pre- <br /> drill the holes and fill the hole with Henry's roofing cement before installing the lag screws. The <br /> installation will be done from the water by boat and will not interfere with vehicle traffic in any <br /> way. <br /> The instrument will communicate through a 12 volt DC cable to a data logger to be housed in <br /> the California Department of Water Resources gage house that is located on the east bank, <br /> adjacent to the piling. For this we will install a 1 inch gray PVC conduit down one leg of the <br /> pylon to the river bottom and then up the levee to the gage house. <br /> We hope to install this equipment during the first week of December 2010. If you have any <br /> question or need further clarification, please call me at 916-826-4519. <br /> Jim George <br /> L <br /> Hydrological Technician <br /> US Geological Survey <br /> 1280 Terminal Street <br /> West Sacramento, Ca 95691 <br /> jegeorge@usgs.gov <br /> Cell (916) 826 4519 <br />
