Figure 6 - Pumps Deployed to Draw Down Storage Impounded by Abandoned Railroad <br />Embankment. Source: RMA, 2013 <br />6.0 Field Investigation <br />The team described above collected onsite survey data during a single 2 hour site visit. A <br />summary of the raw data including photographs, gps coordinates, breach cross sections, high <br />water marks, downstream cross sections are illustrated in Appendices C &t D. <br />A high -level reconnaissance of the drainage basin immediately downstream of Havana Street <br />Dam was performed after the survey of the dam was complete. The main damage appeared <br />to be to the Havana Street road embankment approximately 1/a mile downstream of the dam. <br />The overtopping had resulted in some erosion of the downstream shoulder of the embankment <br />undermining a significant portion of the asphalt surfacing as shown in Figure 7 below. <br />Figure 7 - Overtopping Damage of Havana Street. <br />
