iiortheast. of Amenity Building I in Decernber of` 2007, Slope restoration included construction of a gravity block
retaining wall to support the grade at the slide headscarp and regarding of the slide area below the wall. The
purpose of the work was to verify the restoration was completed in accordance with recommendations outlined in

completed in general accordance with our recommendations arid plans approved by the City of Ednio. nds. The
tipper block wall was founded on firm and stable soils and properly drained and backfilled. Slope restoration
below the wall was completed using amended soils compacted to a, firm condition and graded to an inclination of

sheet flow control boards and landscape planting were satisfactorily completed and would miliffate the erosion
