2. The proposal addresses the existing geological constraints of lhe site, including an assessment of soils and hydrology; and 3. The proposed method of construction wili reduce erosion potentiai, landslide and seismic hazard potential, and will improve or not adversely affect the stability of slopes; and 4. The proposal uses construction techniques which minimize disruption of existing topography and naturai vegett3tion; and 5. The proposal is consistent with the purposes and provisions o(this Ordinance; and 6. The proposal mitigales all impacts id�ntified in the geotechnical report; and 7. All utilities and access roads or driveways to and within the site be located so as to require the minimum amount of modification to slopes, vegetation or geologically hazardous areas, Tne Planning Director's conclusior.s are as follows: 1. The proposed development will not create a hazard to the subject property, surrounding properties or rights-o(-way, erosion or sedimentation to off-site properties or bodies of water. There is an existing singie car garage localed where the proposed garage is lo be constructed. The piuposed garage would be approximately six feet from top of bank and its closest point. There is an existing retaining wali located at the top o( bank which is providing support and erosional stabilization to the slope. The reinforced concrete retaining wall contains an appropriate drainage zone and drainage release pipes. The retaining wall is in good condition and reflects no evidence of detrimental geotechnical impacls (Bruce 2l20/03). 2. The proposal addresses the existing geoloaical constraints of the site, including an assessment of soils and hydrology. This project was evaluated by a geotechnical consultant prior to construction. An evalualion of the slope face veri(ied a relatively shallow depth to very dense glacially consolidated sub-grade soils. The sub-grade soils should provide a minimum of 2,000 psf bearing capacity (Bruce 2/20/03). 3. The proposed method of construction will reduce erosion potential, landslide and seismic hazard potential, and will improve or not adversely affect the stability of slopes. Based on site and geological evaluation and construction of the proposed improvements is feasible. It is recommended that the cutboard footing leg utilize a series of 2" diameter pin-piles. A serir•s of approximately eigtit 2" diameler pin piles should be driven to refusal deoths (per engineers inspection) and incorporated into the new garage footing (Bruce 2/20/03). It is recommended that Dennis Bruce, P.E. be retained to review portions of tlie construction process as described in the geological repert dated February 20, 2003. (�y
