7.2.C. - Page 15 <br /> 2, Provide Model Software Evaluation <br /> Consultant shall review three software suites/combinations for this project: <br /> 1. XP-SWMM (and TUFLOW if required) <br /> 2. MIKE-URBAN, MIKE-11 (and MIKE-21 if required) <br /> 3. InfoWorks lCM <br /> Consultant shall set up the database to accommodate any of these, and the concept is to provide the City <br /> with an expandable model that can be used for other evaluations of the area in the future. <br /> Deliverable:Recommendation of Software. <br /> Schedule: to be completed by April 25,2014. <br /> 3, Develop S.Calibrate Hydrologic/Hydraulic Model <br /> Consultant shall develop a comprehensive hydrologic/hydraulic interior system model component of the five <br /> watersheds and pipe systems.This model will be calibrated with one gage placed upstream of selected pump <br /> stations. A second hydrologic and hydraulic tidal/boundary condition model component will be developed <br /> and then linked to the first model. The boundary conditions model component will include a model of <br /> Redwood Creek calibrated with a gage upstream of the Price pump station, a hydraulic model of the Slough In <br /> front of Blair Island, and a dynamic tidal boundary from Kmart outfall along Smith Slough to the San Carlos <br /> Airport,This second dynamic model component will provide realistic boundary conditions for each of the six <br /> pump stations.Any areas that are expected to have significant overland flow in any of the design events will • <br /> be overlain with a 2D hydraulic model. Based on the relative lack of historical flooding in the five basins,this <br /> may not be needed. <br /> Develop Watershed,Pump Station,Pipe,Open Channel,and Floodplain Database <br /> Consultant shall use the 2010 USGS LIDAR, the 2005 County LIDAR, and FRCS Soils Maps, to develop the <br /> watershed database. Land use will be defined using the 1985 County General Plan (assuming in GIS format), <br /> aerial photography, and field inspections. Land uses will be delineated in polygons for use in the models.The <br /> City's GIS database and the 2006 Storm Drain System Map supplemented with the available as-built <br /> information, available survey data, and newly surveyed pipe inverts will be used to develop the existing pipe <br /> and pump system database. The database will include all the pipe trunks shown in the 2006 Storm Drain <br /> System Map. The 2010 USGS LIDAR and available as-built information and the available survey data will be <br /> used to document the open channel system (including the two 101 bridges). <br /> Develop Interior Model <br /> Develop Existing Condition Hydrologic Model: Consultant shall delineate the Watersheds on a base using the <br /> LIDAR,the City pipe system,the street networks,and property development extents. Watershed parameters <br /> will be defined using existing land use,soil group, percent impervious(from the land use),and flow paths and <br /> will be clearly defined in the project database. Consultant shall conduct and document the QA/QC task in the <br /> data base. <br /> Develop Interior Hydraulic Model Component-- 1D Pump Station Basins and Pipe Hydraulic Models: Once <br /> QA/QC on the pipe data for the major trunks within each of the five watersheds has been completed, <br /> Consultant shall import the data from the GIS Database to the model and verify and parameterize conduit <br /> and manhole connectivity within the hydrologic portion of the model to create runoff output for the full <br /> range of design storms. The detailed sub-watershed runoff developed in the hydrologic component will be <br /> REV:01-15-14!S <br /> Page 12 of 18 <br /> ATTY/AGR.2014.007/Wood Rodgers Storm Plan <br />
