Monohon Landing Road is an important arterial road that connects the City of Raymond with the area west known as Old Willapa. This RAP funded project was located at two perpetual slides (known locally as Thompson Slide) on the road that date back over 50 years. The maintenance of these slides consumed many hours of labor and equipment. The roadbed surface was potholed nearly every day and weekly maintenance was needed for continual grading and surfacing.
Pacific County road crew personnel tackled the most easterly slide first by excavating the area to hardpan soils, constructing drainage control features, installing geotextile and geogrid in the roadbed, and finally placing base and top course. The second year Pacific County road crew personnel excavated the westerly slide to the hardpan soils, and repeated the corrective actions as done in the eastery slide. Finally a small works contract applied hot mix asphalt and guardrail. The project has received much positive public feedback.
