Subject: Plat Approval S-9981S BINGMAN S/D TRACTS A & B
Gentlemen;
We are submitting soil and percolation data for this proposed subdivision. Both tracts satisfy the
requirements of AMC 15.65.180. There are no wells on the adjoining properties that will interfere
with this proposed subdivision. Development of these two tracts will not prevent existing,
undeveloped lots to be developed.
Copies of water well log from Lots 6,9, and 10 of Sandy Beach S/D. These wells are from 179 to
202 feet deep, with recorded yield of from 7 to 30 gpm.
Yours
