rk.? <br /> ity of `I ` MEMORANDUM <br /> rdlk <br /> 1' TO: PHIL HALS, TREET/PARK <br /> River <br /> PE INTEND <br /> SU NT R � <br /> FROM: CLIFF SKOGSTAD,BUILDING <br /> OFFICIAL <br /> DATE: JUNE 29, 1994 <br /> SUBJECT: MAIN STREET HOLE IN THE GROUND <br /> As to your request on June 21, 1994, I did an inspection on this property <br /> which is know as the Main Street hole in the ground. Your concern was to <br /> determine if the cinema wall would be able to withstand a filled condition <br /> upon it. My inspection consisted of a visual inspection only, and I found that <br /> the cinema building is in three different sections. The upper-most part of <br /> this wall is 12 inch blocks with mortar joints. The middle layer is a poured <br /> wall with plaster on the exterior, and the lowest wall is also a poured wall. I <br /> have no concerns regarding the lowest part of this poured wall. It appears to <br /> • be in excellent condition with minimal expansion cracks and I feel this area <br /> would be capable of supporting a filled condition, providing the area where <br /> the floor joists extended into this area was capped off at a 45 degree angle <br /> with mortar and damp-proofed with a tar base or plastic down to footings. <br /> The second part of this wall is approximately seven feet to 10 feet higher <br /> than the original footing. The condition of this part has more concerns in it <br /> since it is a plaster exterior which seems to be deteriorating, along with quite <br /> large expansion cracks running vertically in this wall. Further investigation <br /> should be done to determine if this wall could accept a filled condition. <br /> The third level is of 12 inch block with motor joints. This area would not be <br /> receiving any filled condition and is no great concern except for sealing this <br /> wall and turning it into an exterior wall. Keep in mind that this wall was <br /> designed as an interior bearing wall, and not an exterior bearing wall, since <br /> the old hardware store was connected to it. <br /> In summary, I feel as though the lowest level would be able to accept any <br /> kind of filled condition. In regards to the second level, depending upon how <br /> much fill would be placed onto this section, would determine if this part of <br /> the wall would be able to withstand this filled condition. If the fill was to be <br /> • starting at sidewalk level and ending at the end of the southern footings, <br /> P.O.
