� Gco�echnical Constniction \lonitoring I�inal Lcttcr England Avenuc Lot July 30, 2007 NGA Filc No. 41 1305 Pagc 2 We also evaluated the foundation �ub�rade for thc planned residential structure. Wc evaluated sub@radc by probin� with a '/:-inch diamcter probc rod under moderate pressure. In general the probe rod penetrated between 2 and 4 inches. We interpreted the foundation subgrade to be native glacial material in a dense condi�ion that should provide adequate support for the planned building loads. We visited the site on May 23, 2007 to obscrve the landscaping and erosion control. The areas on the eastem and western sides of thc residcnce, along the property lines, slope moderatcly to steeply down from the back of the residence to the front of the residence. We obscrved exposed soil and near vertir.il cuts on both sides oF Ihe house. Also, we observed exposed soil was nveling over the top oP a rockery at the southwestern corner of thc residence. And below a neighboring rail road tie wall. The soil consisted of native finc to medium s;md. Wc rcconmiend that thcse arcas bc landscaped to preven[ further soil crosion. Based on our part-timc obscr<:!tions, It is our opinion �hat thc carthwork actiaiiics at this sitc. including retaining wall sabgr..dc, retaining wall construction. and thc residenti:d foundation subgrade werc compfeted in generai accordance with our recommendations, and with contract plans and specifications, and should support the planned loads. Flowever, pennanent and effective erosion control measures h,n�c not becn implcmented yct• Thcre is a grcat potential for soil crosion and sloughing to take place if these areas are not addrcssed. We reconnnend that such me:�sures be devised and implemented as soon as possible. We shoidd be retained tu review the erosion control plans. Ne also recommend that we re- cvaluale [hc lin,il crosiun control mcasures prior to thc rainy scason after thc rccommcnded repairs arc implcmentcd. NELSON GEOTECHNlCAL ASSOCIATES, INC, ��
