No. 6143J002 <br />Project: Portland Flume Reconstruction <br /> <br />It is recommended that free-draining, granular soils containing <br />less than five percent fines (by weight) passing a No. 200 <br />sieve be placed adjacent to the walls. Compaction of each lift <br />adjacent to unbraced walls should be accomplished with hand- <br />operated tampers or other lightweight compactors. Over- <br />compaction may cause excessive lateral earth pressures which <br />could result in progressive wall movements. <br /> <br />Existing Structures: Eleven structures have been identified <br />along Portland Flume which may be adversely affected by the <br />proposed construction. Of these, seven are within the portion <br />of the flume covered by this report. These structures are <br />identified as shown on the accompanying site plans. A detailed <br />description and location sketch plan of each structure is in- <br />cluded hereinafter. Photographs of all the structures are <br />available in our project files. <br /> <br />Structure No. SP - (Sta. 11 + 37): This structure is a rather <br />large one story, wood frame motel in good condition. The <br />structure rests upon a shallow concrete step footing with con- <br />crete stem walls along the perimeter and appears to have some <br />interior column footings. Very minor cracking was noted along <br />the north stem wall. The building has a suspended wood floor <br />and crawl space along the east end, and a full slab-on-grade <br />basement at the west end. Footing depth appears to be near the <br />middle of the existing flume wall on the east end and below the <br />bottom of the existing flume in the basement area. Wall loads <br />are assumed to be less than 10 kIf. the north wall footing is <br />located approximately 9 feet from the wall of the existing <br />flume at the closest point. <br /> <br />-7- <br />
