Since I do not have exact elevation inf~on. I caunon~onf1rm that the fence <br />should be IS' high. That appears to be quite high sinee the homes ,~ on a hill. Do you <br />have any contours of the area? . .' . <br /> <br />New ACI sound measurements ...Th_ were ~ to. estimate the level.aUhe Wi1l~ . <br />home. The predicted 58.8 dBA using ~ ~ ~ very. weJl with the. <br />monitored 58 dBA L50 which was measured.9n the 4eck.. "~ it is pretty ~~ <br />that the noise emanates from ACL .However. these new reading, (on the avemge.) ate <br />about 8 dBA lower tban those taken for our previous study SO that some. sipificant <br />mitiaation has a1Ieady been implemented. . . ' <br /> <br />Walll.yout and ACI sources ~ The attac!;1ed uea layout. .shows .whD the majority ~ <br />sources are that appeared to be mAking the most noise (-and the ones 1bat were ~). <br />If it would be more helpful, I could come by this morniDg an" a~ over' this with yoU, <br />since the drawing may be a bit confusing. . <br /> <br />Please call after you have bad a chance to go over.this. ~tt8l (3131-4571).
