Prior to placement of structural fill, the surface to receive fill should be prepared as previously recommended by removing topsoil and fill material, pre- rolling and compaction. Structural fill should be placed in loose lifts not exceeding 8 inches in thickness. Individual lifts should be mechanically compacted to a , uniform density of at least 95 percent of the modified Proctor dry density (ASTM D- 15�7). All fill placed on the site slopes should be properly keyed and benched into firm materials in accordance with section 2-03.3(14), "Embankment Consb7rch'on", of the WSDOT Standard Specifications.

Generally wlien constructing a rockery in a fill section, the fill should be overbuilt and then cut back to allow for the placement of the rockery rock. The space constraints at this site do not allow for this type of construction procedure. Por tliis reason, material placed behind thc proposed rockeries should be placed as stated �o r,Es, l„�.
