So how do you plan Ort d.e.llng WIttI the extra wAr <br />thatwDl be diverted to the soutt)iork? <br />I have many pictures. a. well &SI50mevltleo clips that I ~n.emall you,to show <br />thl) oxtorrt of the floodIng on 'out' aIde of MaClsgy Draw. 1 ttllnk: In.~ WID show you <br />that by diverting water from the north, you may Qr'jly b. shifting the probllm- <br />unless some other wori{ Is perfOnTl8llllS well. I recogntze that the Rockland/oak <br />area is B blgosr problem, and n..d& the mo~ anentlon. but shifting"'. <br />problems southward does not I-.em to be an acceptBbls solullon. <br />Question - Based on eomment!l at the meeting plus what I have heard ,~ <br />other $Oumes. It sounds as if the overafl design tor the Massey Draw drainage <br />through Meadow Aandl was ftawed. or the BlteGution of the dealgn by ~.G <br />developer was poorly e;ll:ecutad. Or bolt'l. I'm not askin9 for- a legal o~nlon,.bu1 <br />simply an explanation Oftt\e proeou- how does Itwork1 I.SSWTIIIt18 basK:ally <br />similar to 08.9tgnlng and bulldu,g. house. Firs1, a flood control8n~n88f1ng firm <br />etaatu a design and 9811 it approved by the County. Then the bUilder/devotoper' <br />musllol1ow the pion, fcDowed by I CoUrfty inspection to certify that the developer <br />completed the wor~ per the apprclled daslgn. Is this basIcally correct? <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />David - First off, thanks for having the meeting LalOt 1\i9hf. Seeing some of tile <br />~oncepts and ideas helps.
