This factor should be taken into <br />consideration before their use over more proven and time tested <br />techniques. <br /> <br />With any method of flood protection it is essential to seal <br />-- -- - --sewel li,ies, drain,ilt:~ amI ulht:I wuduillhal witr-allow warer 10 <br />bypass the expedient flood work an flood the area. It is also <br />important that once these systems have been plugged, provisions <br />may be needed to pump sewer lines or systems to prevent other <br />forms of flooding. <br /> <br />As part of the planning process, options should be listed for the <br />placement and use of expedient flood works. Several options may <br />be presented for each situation as this allows for adaptation to <br />changing water conditions, resource capabilities, and time before <br />the crest.
