We will send a cost proposal request on Monday with further details. The City would still prefer that the light pole gets moved,but we will likely adjust the location from that shown on the current drawings. Marc/Randy H.-if you have feedback regarding the exact location let us know. I believe we are well away from the electrical lines with the new location,but please confirm Travis Anderson,P.E Strand Associates.Inc't dmiBIODLlarl 608.251.4843 ext 1023 traus.andersonostra<nd.com I www.strard.com P.E.(a,WI) Excellence in Engineering Since 1946.
