PROJECT APPROACH <br />While detailed metadata are not .available for the NFIP community participation dataset, a data <br />dictionary is available. The data dictionary lists all the attributes in the table along with their <br />definitions and any codes. An update schedule is not included, but Riverside does not expect the <br />dataset to change frequently. For the Flood DSS, the dataset will be scheduled for update every <br />six months. <br />FEMA MIP WMP Web Service - FEMA provides access to the National Flood Hazard Layer <br />(NFHL) through a Web Map Service (https://hazards.fema.~ov/femaportal/wps/ op rtal/ <br />NFHLWMS). The NFHL is a computer database that contains FEMA's flood hazard map data. <br />The data include flood hazard .information and supporting data. Riverside will evaluate the <br />utility of this web service for the Flood DSS. <br />Weather Modification Data -The Flood DSS prototype included weather modification data <br />created by HDR that consisted of Central Rocky Mountain .Generator Sites and Central Rocky <br />Mountain Target Sites. The data included in the original prototype was incomplete and likely <br />outdated. For the Phase I Flood DSS, Riverside will work with the CWCB and HDR to obtain <br />an updated dataset of generator and target sites. The datasets will be reviewed for their <br />completeness. If possible, the CWCB should establish an arrangement with HDR to receive a <br />copy of the data whenever it is updated. <br />Flow Conditions -Historical and real-time streamflow data are available from the State of <br />Colorado in HydroBase and from the USGS in the National Water Information System. Given <br />the easy accessibility of these data, there should be minimal data collection efforts related to <br />these data layers; rather, the effort will be focused on developing an automated process for <br />integrating the data into the Flood DSS and updating the data on a frequent basis (see Section <br />4.6.2). <br />SNOTEL Sites -The SNOTEL SWE and soil moisture data are available from the NRCS in a <br />variety of formats from their ftp server. One format that- was not available at the time of the <br />prototype development is a Google Earth KML file (Figure 4-6). If this data format can be <br />integrated into the Flood DSS, it will require little data collection effort. An automated <br />procedure will be developed to obtain the daily layer from the NRCS. <br /> <br />0 <br /> <br /> <br /> <br />I~ <br /> <br /> <br />Lam' <br />DNR RFP PDA-923 40 ~ R ~ V E R S ~ ~ E <br />
