Abstract
Deformation of man-made structures in and adjacent to the public right-of-way in the Manoa Valley was mapped to locate existing and incipient slow-moving landsliding. The results are shown on two kinds of maps. One map consists of four sheets that show field observations. The other, an interpretive map, shows locations where there is evidence of landslide movement.
No slow-moving landslides were found that are similar in size and degree of development to the existing Alani-Paty or Hulu-Woolsey landslides. Nine areas, however, were found where deformation might be related to such movement, including five sites of small landslides in fill and four sites where deformation is consistent with the early stages of development of a larger landslide.
Locations of all nine areas that show evidence of recent or incipient movement are plotted on the interpretive map. For these areas, possible courses of mitigation range from no action to monitoring and remediation. Four areas that have the greatest potential for enlargement and movement are in Woodlawn and within several hundred feet of the existing Alani-Paty and Hulu-Woolsey landslides.
