. . • the site is relatively stable; • the risk of damage to the existing structures or to adjacent properties from soil instability during and following construction will be minimal, subject to the conditions set forth in the report, • the proposed construction will not increase the potential for soil movement. The repon includes recommendations for site prepazation, excavation, structural fitl, foundation support, slab-on-grade, retaining structures, drainage and utilities. Thc recommendations include, but are not limited to, the following: 1. It should be the contractor's responsibility to maintain safe slope configuration. It may be necessary to cover temporary slopes. All temporary excavations should be shored or sloped back at one horizontal to one vertical. Seeps may occur during excavation. 2. If structural fill is needed, it should be placed in maximum 12-inch lifts and compacted to 95% of maximum dry density. A representative from a qualified testing lab should be on-site ro monitor � the placement of the fill and verify that the required compaction is achieved. � 3. Founriations within 15 feet of the top of slope should be placed upon drilled piers to support the foundation without loading the top of slope. The remaining portions of the structure may be placed upon a conventional spread footing. € 4. All surface drainage should be directed away from the existing and proposed structures. All roof drains should be tighdined to the stormwater collection sys[em. 5. The final plans shoulri be reviewed by the geotechnical engineer. 6. Excavation activities should be monitored by the geotechnical engineer. i: During the public comment period for this application, the City received a comment letter from the � adjacent properiy owner to the south (Soriano-6/I1/Ol). The letter raises a concern about the proximit�� of the proposed building on Lot 2 ro the existing condominium structure located at 1930 Grand Aver.ue. It states that the strucmre at 1930 Grand is presently located approximately three feet ftom the properry line. It also sta[es that the foundation for this structure is the original foundation upon which a house was contructed in 1910. The letter raises concerns about potential impacts of wnsttuction (i.e., excavation, vibration) on the condominium structure due to the two buildings being located less than 10 feet from each other. The letter a� o raises concerns about ban}: stability due to the building being located partially on the bank. These latter concerns are addressed in the soils reports for the project. See also the response letter from Richard Sullivan dated June�3;2001. 27 The Applicant's soils report contains specitic recommendations that address the proposed building contruction (see above findings). The contractor, owner, and soils engineer will be responsible for ensuring that excavations are petformed in accordance with these recommendations. I I 10 � I �/y
