7.2.C. - Page 16 <br /> directly linked to conduits and open channels in the model hydraulics component. Once model stability for <br /> extreme events is assured, Consultant shall run the model for the full suite of design storms with detailed <br /> representation of system tail water conditions. Develop 2D Existing Condition Floodplain Model: <br /> The interior model will include the infrastructure identified in Table 1 below: <br /> Table 1:Interior ModelInfrastructure Included <br /> Price 0.0 1.5 14 <br /> Veterens 0,0 1.5 12 <br /> Bradford 0.0 2.0 26 <br /> Oddstadt 0,0 1.4 14 <br /> Maple and Kmart ■ 0.3 ME- 14 <br /> Redwood Creek 0.8 0.3 MEM <br /> TOTAL: 1.1 8.2 82 <br /> Develop Tidal/Boundary Condition Model Component: Consultant shall develop open channel hydraulic <br /> models for reaches of K.-Mart, Redwood Creek, and the channel along 101 and Blair Island from the Bay to <br /> the end points. <br /> Develop Tidal Boundary Conditions. FEMA is developing a new regional South Bay 2D model. DHI has been <br /> brought on the team so that the most recent version of this model can be utilized for development of the <br /> tidal still water elevations. Consultant shall use the most recent version of the South Bay 2D model to <br /> develop tidal still water elevations. <br /> Calibration:Consultant shall place a recording gage at the following locations: <br /> 1. In interior pipes upstream of either the Maple or Bradford Pump Station <br /> 2. In Redwood Creek underground pipe upstream of Bradford Pump Station <br /> Consultant shall use Data from the gages in the first significant storm of the season to calibrate the <br /> hydrologic parameters. The first gage will help calibrate interior system models, and the second will be used <br /> to calibrate the Redwood Creek hydrology In the tidal/boundary condition model. Doppler RADAR data for <br /> the selected storm will be collected and used as input to the calibration model. Consultant shall collect and <br /> compile the Doppler RADAR and gage-adjust with a resolution of 1 square kilometer, at 5 minute increments. <br /> The gage adjusting is done with local on the ground precipitation data to calibrate the RADAR depths to <br /> actual depths. <br /> Deliverable:Calibrated Interior H&H Model of Five Watersheds, Linked to Calibrated Boundary Condition <br /> Model. <br /> Schedule: to be completed by July 31,2014. <br /> REV:01-15-14.t5 <br /> Page 13 of 18 <br /> ATTY/AGR.2014.007/Wood Rodgers Storm Plan <br />
