Dear Paul.


I have reviewed the revised stormwater                     Management          Plan completed           by BE Collective [#6532, C200, May
2015, Rev 4J which shows the stormwater                      infiltration tank relocated            from the rear of the residence                 Ibehind
the paoLI to the southern              boundary        and closer       up the slope [between               the existing concrete                patio and
retaining walls!.


A further review of the existing report, "Geotechnical                        Investigation",       #112-14608,        Jan 2013 by Soil Surveys,
was conducted         and I confirm that this new location of the infiltration pit will have no adverse effect on the
existing structural        elements,        Further,     the concrete        patio and pool are both piered using steel screw-in
piers as per our original structural               documentation,


It has been concluded            that this geological          region has a moderate/high                 risk of slope instability, However,
with the adoption of the recommendations                       contained       within the referenced            report from Soil Surveys and
with the new location of the infiltration pit; this risk can be maintained                             as "low",


Please don't hesitate to contact me with any queries regarding                              this letter,



Yours faithfully,
Scott Brimetow
