A :meeting war held on the site last week with Ar. Qullickson, dike
Caffron, of the City of Orono, and -myself present to review the findings
of the tests and discuss the possible systems, locations, etc., and
how they would best be utilized on.this property. The conclusion was
lat a mound system would be mist satisfactory in the location
the sketch.
3 mound system using a rock area of 10' x 50' with 3
rated distribution pipes is recom•lended. The uphill face
and should have a varying slope which is flatter at the
order to divert the runoff around either end. The details
and construction are shown in the "Orono .Bound Package".
r information is required please feel free to call me.
