Placer 267 CAPM Project

Placer 267 CAPM Project

Caltrans proposes this Capital Preventative Maintenance (CAPM) Project along State Route 267 (SR 267) in Placer County between Post Mile (PM) 0.0 at the Nevada County Line and PM 9.63 at the intersection of SR 267 and Dolly Varden Avenue. This project proposes to cold-plane and overlay 0.20-foot of Hot Mix Asphalt-Type A (HMA-A) on all lanes from edge of pavement (EP) to EP. The existing southbound truck climbing lane would be extended approximately 2,800 feet from 370 feet south of Martis Peak Road (PM 6.30) to approximately 700 feet past Carnelian Bay Avenue (PM 6.80). This work would require roadway widening to accommodate the added lane and the construction of a 3,145-foot-long soil nail wall adjacent to SR 267 at the easterly cut slope and a 262-foot-long retaining wall along the embankment over the 78-inch-diameter corrugated metal pipe (CMP) culvert just past Martis Peak Road. The proposed project would also extend the life of existing drainage systems in poor condition by replacing or lining. Other work would include replacing nonstandard guardrails to Midwest Guardrail System (MGS) with end terminals that meet current Manual for Assessing Safety Hardware (MASH) standards; replacing HMA-A dikes with concrete dikes; upgrading sign panels and striping to meet current standards; placing shoulder backing; constructing new or modifying existing stormwater treatment facilities between PM 6.00 and PM 7.00 to treat the stormwater runoff from the newly widened roadway; and rehabilitating the existing cut slope for SR 267 northbound (NB) on the east side from PM 4.95 to PM 5.07 (540-foot-long) by excavating and replacing rock slope protection.
