2 APPENDIX A EXISTING CONDITIONS HYDRAULIC MODEL UPDATE TECHNICAL DATA

3 MEMORANDUM 5.0 Datum Adjustment for East Lake, Curiosity Creek, and Duck Pond Watersheds As required by the scope of work, the datum adjustment from NGVD 929 to NAVD 988 has been conducted for all the three watersheds following the steps below: () NGS VERTCON was applied to find out the conversion factor (CF) for each non-dummy junction within a particular watershed: (a) East Lake has 484 non-dummy junctions, the CF ranges from to (in feet); (b) Curiosity Creek has 3 non-dummy junctions, the CF ranges from to (in feet); (c) Duck Pond has 272 non-dummy junctions, the CF ranges from to (in feet); (d) For all the dummy junctions, the CF is set as zero. (2) A VBA macro has been developed to apply datum adjustment for.s4d files of the existing model: (a) Since the CF is junction-based, the information will be automatically updated whenever a junction-related elevation appears, as follows: C Card: ZP (N,), ZP (N,2) (invert of conduit N at two connected junctions, respectively); D Card: Z (J) (invert elevation of junction J), Y0 (J) (initial water elevation of junction J ); E2 Card: QCURVE (N,I,J) (elevation of point J corresponding to surface area of storage junction). (b) For elevation of cross-section in C4 Card, average CF of the two connected junctions of the reach was calculated and applied as the CF of the cross-sections corresponding to the reach. (c) For the elevation of weir crest in G Card, the same method as above has been applied to conduct the datum adjustment. (d) Some elevations (usually set as a large number such as 99), are remained the same in the.s4d files, including: Ground elevation in D Card Junction crown elevation in E Card Elevation of weir opening in G Card (e) Datum adjustment for the Orifice Invert ZP (I) in the F Card. (3) QA/QC with the updated.s4d file, including: Rerun the existing model while keeping all the other condition the same; Storage verification based on the -foot contour (in NAVD 988) and most recent aerials. Attached please find sample datum adjustment for USF East portion within Duck Pond Area. g:\county - hillsborough\ _curiousity_duckpd_eastlk\working_folder\task-5_datum_adjustment\memo_datumsadjustment.doc Engineers/Planners/Scientists Hidden River Parkway, Suite 200, Tampa, FL 33637, (83) , FAX (83) Page of
