The details of a settlement monitoring program (SMP) at a multipurpose site development project are presented in this paper.

The SMP consisted of constructing:

(1) two test fill pads, one over about 55-year old waste and the second one over about 45-year old waste;

(2) thirty shallow surface monuments, and

(3) four deep (Sondex) settlement monitoring systems. These settlement measuring instruments were monitored for about three years. Based on the evaluation of these monitored data the coefficients of secondary compression for municipal solid waste (MSW) were estimated to be 0.01 due to external loading for test locations, and 0.39 and 0.12 due to self-weight of 45-year old and 55-year old wastes, respectively. The results of this SMP can be used to locate structures in different areas at the site depending on their relative sensitivity to settlements. Also, using these results, a predicted settlement contour plan can be prepared that may be used for site grading and drainage plans.
