SirenDear Jeanne, <br />We have reviewed the request for placement of an Emergency Preparedness Siren <br />in the vicinity of NSP pole #40 within the Windjammer Lane right-of-way. <br />1. We recommend that the siren be placed atop an anodized aluminum pole which <br />is the same type of pole used for the siren at the water treatment plant. <br />An anodized aluminum pole would be a long lasting pole and would require <br />little maintenance. <br />. ii <br />2. <br />3. <br />4. <br />Controls for the siren must be attached to the pole in watertight enclo­ <br />sure 10 feet off the ground. An antenna is situated at the controls for <br />activation of controls by radio signal. <br />The siren rotates 359* and then reverses direction back to its original <br />position. The siren is activated for 3 minutes when tested on the first <br />Wednesday of each month at 1;00 P.M. A 125 decibel siren will register <br />125 decibels at 100 feet and 70 decibels at 4500 to 5000 feet. <br />There is currently 1 siren located in Navarre and 2 in Long Lake. An <br />additional siren is needed in the Windjammer Lane area as it is a popu­ <br />lated area currently without a warning device. The siren is necessary for <br />public safety in the event of a tornado or other catastorphic events. <br />Placement on high ground is preferred so that the 4500 feet radius of <br />coverage is met. <br />The concrete <br />feet deep. <br />footing for the pole is anticiapted to be 24* in diameter 6 <br />If you have any questions, please contact this office. <br />Yours very truly, <br />BONES'- :0, ROSENE, ANDERLIK & ASSOCIATES, INC. <br />Michael C.
