Brian & Michele,
On 9/17 and 9/20 1 conducted a bottom of septic bed inspection at the above property and found
the depth of excavation consistent with the approved plan. The inspections were done on 2
different days since the field was excavated/filled with clean sand in stages due to the length of the
field (75 feet)
I will complete and sign the installation card with these dates upon submission of the final as-built
plan unless you would like it done sooner.
Thank you.
