Hi Chris,
We observed proper drainage installed for the continuous block wall installed along the south side of 707 and 711 Main
Street. We documented the drainage for the wall in the attached field report. The field report states 707 Main Street
but is applicable for both 707 and 711 as the wall is continuous across the properties. Let me know if you need anything
else from us.
Thanks,
Henry T. Wright, P.E.

As requested, ESNW representative was on site to observe wall construction:
ESNW rep performed compaction testing on SG of 1 st tier block wall on southern site boundary. An 18" vertical
section of washed drain rock was observed to be directly behind the wall face, with native materials being placed
behind the drain rock. A perforated drain pipe was observed to be installed at the base of the wall face, with drain
pipe infiltrating into a sump drain. Synteen SF 55 geogrid was observed to be installed behind the wall face. ESNW
rep performed compaction testing on backfilled soils, and observed them to be adequately compacted to at least
95% of the modified proctor at the locations tested.
ESNW will return as requested.
