<br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br /> <br />./ Digital terrain data for Area 3 (eastern most - DTM03.dxf) showed an abrupt 6 <br />foot break (waterfall) along the river near coordinates x=3666345 y= 1518699. <br />This data set also had inconsistent elevations scattered throughout its boundary. <br />Actions Taken: <br /> <br />. The COE informed the CWCB of the initial findings in early 2000. <br />. The CWCB and the COE jointly agreed to contact the mapping contractor <br />(Kucera) regarding the inconsistent data. <br />. The COE contacted Kucera on or about 14 April 2000 (spoke with and faxed data <br />to Mr. Scott Antolovich) <br />. The COE and CWCB met at the COE office on 25 April 2000 to discuss the <br />inconsistent data. <br />. Kucera resubmitted (through e-mail) dtm data for Areas 2 and 3 on June ih and <br />8th respectively. These files came as Microstation files. <br />. There was no data resubmitted for area I <br />. The review process was repeated for the two resubmitted Areas. <br /> <br />Presentation of Data: <br /> <br />AREA I (original data from 8/99): <br /> <br />. 1 sheet layout - overall area map <br />. 17 composite plan view plots (I" = 400') <br />. 4 profile plots (H 1"=400' /V 1"=10') <br /> <br />AREA 2 (revised DTM data) <br /> <br />. 1 sheet layout - overall area map <br />. 17 composite plan view plots (I" = 200') <br />. I profile plots (H 1"=400' /V 1"=10') <br />. 9 cross section sheet plots (H 1"=40' / V 1"=10') <br /> <br />AREA 3 (revised DTM data) <br /> <br />. I sheet layout - overall area map <br />. 10 composite plan view plots (I" = 200') <br />. 1 profile plots (H 1"=400' /V 1"=10') <br />. 5 cross section sheet plots (H 1"=40' / V 1"=10') <br />
