The effect of this change could cause damage to the <br />existing tree stand, resulting In a future stand of “dead and unhealthy" trees. <br />_ . . • ... • . • . _ _J ^ ^ J ^ ^ 4m <br />» IPresently, there Is field evidence that the existing stand of trees Is located <br />In a low, wet area and that during Intense storms, standing water may be <br />present. However, It would be very difficult, nearly Impossible, to predict the <br />future effects that the proposed basin will have on those trees. <br />If you have any questions or comments, please feel free to give m a call. <br />Very truly yours, <br />SCHOEUt S MADSON, iNC. <br />John Karwacki, P.E. <br />.. -»Vf/., -V. <br />mmm- m <br />^v; V • ...,: a <br />i ;; ■■ ■•<■ <ia«si^ <br />mmM g:? <br />Bissi <br />W^yr • V-V : <br />II <br />tv'-- ••..«..‘fc*^^ <br />p->wmmm V:S <br />mymm^ '■ ‘.Mi:':eB. :■ <br />.• , . ,: ■; <br />ll!S"tl!>.‘ v'.: ' ■ . ■ <br />■: ■ V ‘‘' ??: ■ <br />PI? <br />•og- • ■^ <br />B::IWfS <br />.V|' ^ <br />wy <br />.. y ■'.
