'I'I��� <br />i�►-�i�������r� <br />�����i���������. ��; <br />September 29, 1993 <br />Mr. Ted Budden <br />Building Inspector <br />City of Everett <br />3200 Cedar Street <br />Everett, WA 98201 <br />Re: Anderson Residence at 2010 Mukilteo Blvd. <br />Dear Mr. Budden, <br />BY FACSIMILE <br />This letter is in response to your request for clarification <br />reyarding an over-excavation for the footinq of an adQition <br />to the above referenced residence. Due to a previously <br />buried stump falling in the line of the footing excavation, <br />over excavation in an area 12 ft. long and approximately 3 <br />ft, wide was required. Once firm qray clay material was <br />encountered, the contractor was instructed to stop and clean <br />up the excavation. Following that, the contractor was <br />instructed t� fill the excavation 30 inches deep with 2 inch <br />to 4 inch quarry spals. Geotechnic fabric was to beplaced <br />over the spals and then crushed rock to fill the void to the <br />point of the bottom of the footing. In actual construction, <br />the contractor used pea gravel which does not appear to <br />adversely affect the bearing of the footing. <br />The method used above was used as a precautionary measure to <br />compensate Por the over. excavation of the footing area. <br />While a geotechnical engineer could have been involved, it is <br />my opinion that such recommendations would not exceed the <br />construction as outlined above. The one story light <br />construction nature of the addition does not overload either <br />the existing bearing nor the gravel fill. <br />If you have additional questions or concerns, please contact <br />me at 828-614fr�—� <br />�ck Driftinier AIA, Presi�ent <br />The Driftmier rchitects, P.S. <br />cc: Mike Kelly, Contractor <br />Bob Anderson, Owner <br />; � t��.ki� <br />
