Memorandum MATERIALS AND GEOTECHNICAL BRANCH SOILS AND ROCKFALL PROGRAM 4201 EAST ARKANSAs, DENvER, COLORADo 80222-3400 (303) 757-9424 DATE: February 27, 2004 TO: Wendy Turner, Region 4 Engineering FROM: Ty Ortiz, Rockfall Program Manager SUBJECT: Rock Slope Stability, SH 14 — Approximate Mile Marker 16.5 Regarding the road cut on SH 14 at mile marker (MM) 116.5, the most recent site visit was on January 13, 2004, with Ms. Wendy Turner of Region 4 and Mr. Jason Stutzman of the Ft. Collins Park Planning and Development Department, and Mr. Robert Florez and Ty Ortiz of the Rockfall Program. Our understanding of this road cut is that the project was funded and managed by the City of Fort Collins with input from the CDOT. At this point, construction is complete, however, there are concerns regarding the slope stability of the road cut at this location. This report summarizes our evaluation of the rock fall potential and rock slope stability of the road cut and provides recommendations for rockfall and rock slope mitigation. Our evaluation is only for the area of slope disturbed during the construction of the road widening needed to accommodate improvements made to the Gateway Park entrance. A comparison or evaluation of any adjacent rock cut is not considered. Figure 1 outlines the area of slope evaluated. Site Description and Observations The slope is located on the eastbound lane of SH 14 near the Gateway Park entrance. The cut is around 20 ft in height and located within highly weathered metamorphic and igneous rock. Large boulders, up to about 10 ft in diameter, which appear to be partially supported by a soil matrix, are exposed in the cut. Several small, loose boulders were also Figure l: View of slope looking eastbound Rock Slope Stability, SM 14 —Approximate Mile Marker 16.5 Page 2 of observed. The ditch at this location does not seem to be acting as an adequate rockfall catchment area. Conversations with Region 4 Maintenance personnel indicate the same. Figure 2 shows a panoramic view of the slope face. Figure 2: Panoramic view of slope face being considered for mitigation Conclusion and Recommendation The slope, in its current state, does not appear to be stable. Conversations with maintenance indicate that rock is often found in the roadway in this area. Rockfall at this location is most likely the result of cobbles and boulders raveling from the slope. The sandy, soil matrix helping to support these cobbles and boulders is easily eroded during heavy rain and snowmelt. Erosion of this material causes undermining of larger boulders, which eventually ravel from the slope. Since the ditch does not serve as an adequate rockfall catchment area, the boulders roll onto the highway. Based on our observations of the slope, the following mitigation alternatives or combination of alternatives are offered: 1. Since the underlying cause of rockfall at this slope appears to be erosion of the soil matrix, erosion control by applying shotcrete to specific locations throughout the slope can be utilized. 2. A rockfall barrier can be installed at the base of the slope, which would reduce the amount of rock rolling onto the highway. Rockfall barriers can range form Type 7 barriers to rockfall fences. The amount of shoulder available at this location should be considered when evaluating the constructability of this option. Draped netting can be installed to help control the rockfall and reduce the amount of rock reaching the travel lanes. When evaluating the effectiveness of this option, wire rope or Tecco netting should be considered. Rack Slope Stability, SM lt—APpraximate Mile Marker IQS Page 3 of 3 4. The slope angle can be reduced and an adequate catchment area can be created with additional excavation. Also recommended in addition to the mitigation alternatives listed above is the installation of a buttress to help support a large boulder, which has the potential to be come significantly undermined with the continued erosion of the soil matrix. The large boulder is outlined in Figure 2.
