5) Public health, safety and welfare both on and off the subject property will be enhanced as a rer;ult of ths replacement of a structurally deficient reta`ning wall constructed of wooden (railrc�ad ties) situated at the top of the steep slop. 6) The lot is currently developed with a single-family structure and this preposa� does not increase the developed area. Conclusion: 1) The existing retaining systern is inadequate and must be replaced in order tc remedy the settlement occurring belween the concrete slab and the top af the bluff on the subject site. 2) The subject property has a steep slope (41%) in the rear of the hort�e and a wooden retaining wall exists 2bout six (6j feet beyond ;he concrete slab at the rear of the hort;e which the applicant is proposin3 to replace with a more permanent structure. 3) According to the Geotechnical Report for the subject site, the ground surface between the concrete slab and the wooden retaining wali has settled about 4 to 5 inches, probably due to settlement of the soft fill in this area and probably outward movement of the retaining w211. 4) It is the opinion of the Geoter,hnical Consultants (RMI Associates, LLC) that the site is compatible, from a geotechnical engineering standpoint, with proposed developments planned on this lot, provided recommendations and precautions herein are followed. The underlying deposits into which they will be built typically liave nigh strength and are considered stable with regard to deep-seated earih movement. The native soils should provide adequate support. We recommend tr,at a replacement retaining wall be a reinforced concrete wall extending through any loose surficial soils or fill and be founded on the very dense unweathered till about 6 feet below the current ground level. 5) Temporary cut-slope stability must be continuously observed by the contractor and the centractor must maintain safe slope configurations and monitor the nature and condition of cut slopes including subsurface materials and groun� water conditions. Decision The City of Everett Planning Director has approved the proposed construction oF a retaininq wall in the rear of the house over four(4) feet tall in the side yard setback. The specific proposal is to construct a concrete relaining wall 50 ieet by 6 feet to cover the entirc• p�operty line (approximately 76 feet plus 8 foot bow) to ensure that there will not be any further erosion. The applicant must comply with all of the follo�ving conditions. 1) Any permits necessary for the construction of the proposed retaining wall must be obtained by the applicant prior to construclion; 2) The contractor shall eract a silt fence beyond the new retaining wall unless the construction takes olace in a period of dry weather; and � ��)
