980404B Final Inspections Summary,6/30/98,page 2 of 3 a 3. Part-time testing of compaction of fill material placed on the benches to build the new fill slope; 4. A final inspection of the completed fill. Future Required Maintenance The owner and future owners must understand that the long-term successful performance of the fill may require some maintenance. The owner is responsible for maintaining drainage and repairing any erosion if it occurs. This includes, but is not limited to the following: • The access road must be graded so that runoff is directed down the center of the road and into the catch basin of the drainage system. The catch basin(s) must be keep free of debris so that the system does not become clogged. A clogged system could cause surface water to flow over the side of the slope with possible erosion or sloughing resulting. Catch basins should be inspected at least monthly. This includes any catch basins at the top of the plat around residences. • Any erosion channels should be filled with compacted fill or crushed rock to reduce further down-cutting. • The fill slope was hydroseeded as per our design. We recommend that the slope be kept vegetated. Trees may be planted by mixing organic peat moss into the planting holes. Care must be exercised in watering new plantings so that water does not flow over the slope and cause erosion. • It is our opinion that any fill slope should be monitored. The owner should watch for signs of any erosion or larger soil movements. Any signs of soil sloughing or large movements should be immediately brought to the attention of GeoSource Engineering. Closure Based on our observations, testing and inspections during construction, it is our opinion that all geotechnical-related work observed by us, was performed, or was made to perform, in suitable conformance with our approved design. Geotechnical-related work on this hillside fill is now complete.
