adequate amoWlt offine and course matenal to fill all vOids after compactIOn The matenal
should be free of slIt, clay or orgamC' matenal that would react adversely to compactivc effort or
to vanatlollS in moisture content
5) Compact aH areas after each hft A 6000# Vlbratol)' compactor IS recommended, optimum
mOIsture content can be Identified from the crushed rock supphcr
Compaction requirement is: 91 % relative compaction, modified proctor
Contact our office for compactlon testing b~ proof roll, or make arrangements \Vlth a testmg
service to perform a test to achIeve the reqUIred compactiOn
6) Dramage' provide perimeter drainage whl~h IS led to the storm water system
A recommended solutIon IS a 4" PVC drainpipe \\,inch is surrowl.Q_ed Wlth a mInImum 15'! radIus
of drain rock and is wrapped Wlth a gco-tcxtilc Dramagc should be located at the lo\\'Cst

7)Roofrain leaders must be installed and maltltamcd so as to prevent roof stonn water from
migrating mto the cngmecrcd fill
SpeCIal oonsideration should be given to foundaHon elements, so as to avotd crackmg We
recommend that all fowldatlon elements be remforced and detailed to accommodate expansive
