    The Cerro Grande fire of 2000 destroyed vegetation which resulted in dramatic increases in stormwater run-off in the canyons surrounding Los Alamos; only 2% of the watershed area was not burned. The increased flows through Pueblo Canyon were carried by an 86\u201d diameter storm drain which transported the flow beneath Diamond Drive. Hydraulic modeling indicated that under these increased flows, a 1 in 100 year storm would overtop Diamond Drive, which stands some 140\u2019 above the invert of the storm drain. It was calculated that a 12\u2019 diameter tunnel would be required to accommodate these flows. In addition, debris basins, silt traps, culverts, and channelling works would be necessary to control the flows. Mechanically Stabilized Earth (MSE) and retaining structures would be constructed to retain and reinstate highways washed out during storm events.<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n

    URS Corporation designed the solutions with assistance from Maccaferri\u2019s technical department. The project consisted of; Three MSE and Gabion structures: Max. 36′ high MSE structures using Paralink\u00ae and Terramesh\u00ae soil reinforcement geogrids, with a 9′ high gabion wall above, supporting North Road Retaining walls: Terraced gabion walls of 30\u2019 total height (12\u2019, 12\u2019 and 6\u2019) supporting Diamond Drive. Channeling works and sediment \/ debris traps: Gabions, Gabion mats\u00ae and wire enclosed rip-rap were used to form drop structures and channel linings to control the flow and prevent sediment and debris from damaging downstream structures. The MSE structures incorporated different varieties of geogrid within the design; Terramesh\u00ae, a steel woven wire mesh geogrid used as secondary reinforcement; and Paralink\u00ae, a polyester geogrid with a tough polypropylene protective sheathing used as primary reinforcement. Paralink\u00ae strengths of up to 55,000 lb\/ft (800 kN\/m) were used on this project. Structural backfill was compacted in layers upon the reinforcing geogrids as the embankment was constructed<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>
