                            PROPOSED RESIDENCE

       This FOS result satisfies the generally accepted minimum requirement for hillside development (i.e.
        minimum FOS of 1.5).

Our analysis indicates that the proposed development will achieve the required minimum FOS against slope
instability. Subject to implementation of the recommendations made in Section 7 during building works,
there would be a Low Risk of slope instability affecting the proposed residence.

General recommendations to help maintain the stability of the site are given in the document “Some
Guidelines for Hillside Construction”, which is attached in Appendix C.
