A total of one 6-inch diameter soil test boring will be drilled using 2. 25-inch continuous hollow stem flight augers. The boring will extend to a maximum depth of feet below current site grades using a truck-mounted drill rig. The samples will be containerized in glass jars for geotechnical classification and laboratory testing. The boring will be left open for a period of 24 hours to collect groundwater information. A slotted pvc pipe will be inserted into the hole at the completion of drilling. The pvc pipe will be capped to prevent runoff from entering the bore hole. After groundwater reading the borehole will be grouted with bentonite slurry 2 lbs of bentonite to 1 gallon of water and the auger cuttings and all other investigation derived waste idw will be containerized in sealed drums per ddoe permit.

The earth retention consists of a driven steel h-pile system at the complete perimeter of the below grade parking structure. The earth retention system will use a combination of tiebacks and interior steel braces to support the lateral forces. The adjacent townhouse structure shall be use bracket piles to support the existing building foundation.

Revision to permit #sh1700003 to sheeting and shoring activities will begin roughly 5-7 weeks after ntp is received. The duration is 60- days. Driving of piles will be done from inside the property lines and will start along the south elevation. Immediately following the completion of driving these piles the bracket installation will proceed so that the underpinning can be in place and the adjacent property will be stabilized prior to any mass excavation proceeding. Once driving of piles has reached 75% completion, excavation and lagging activities will begin. When the excavation has reached tie back wale elevation, roughly 8 below grade, tie back and wale installation operations will commence. The west side of the property will be excavated to the subgrade elevation while the east side will be left at a 1. 5:1 slope. The sloped material will be left in place till the rakers on the east side of the property are installed and in position to support the excavation on this side. At that
