The BNSF railway was notifIed of this problem <br />on May 6, 1999. An inspection of the reservoir on May 11, 1999 indicated that problem was <br />getting worse. Railroad personnel visited the site on the afternoon of May II, 1999. <br />Subsequently, the railroad placed a speed limit on all trains in the area and took action to make <br />the necessary repairs. The railroad dumped at least 69 train cars of riprap at this site to stabilize <br />the slide. With the slope stabilized, the railroad began placing riprap in specifIc areas that <br />required protection. Incidentally, the Corps made arrangements to purchase riprap from the <br />railroad. The riprap will be stockpiled for future emergency use. <br /> <br />INTER-AGENCY COORDINATION EFFORTS <br /> <br />Reports and advisories addressing the potential for heavy rain were fIrst issued early on the <br />morning of April 28, 1999.
