PAGE 4 of 4 – Ward Variance Request
The proposed geothermal aqueous closed loop system for the address listed on
page 1 is in need of a distance requirement variance. The residential and
accessory structure size and positioning are impeding the location of the
geothermal closed loop field, causing the boreholes to be located within the
required 15’ building perimeter setback distance respectively. We are proposing
to locate the vertical bores to the left of the residence. The vertical bores will be
grouted from top to bottom with high quality, low permeability grout using the
tremie method to assure the bore hole will be a solid plug of environmental
protection. The bore holes we construct will be the safest points of ground water
intrusion on the property when compared to the native geology. We will
construct triangulated borehole construction maps for each hole for permanent
locating and install metal detection tape in all of the horizontal connecting
trenches to facilitate easy bore hole locating if ever needed for any reason. Due
to the fact a geothermal vertical closed loop is constructed in the same manner as
an abandoned well and does not move water, does not contain well screens or
casing and is not an actual water well, fu ture service will not be required.
