.- STEEP SLOPE BUFFER REDUCTION SEAWAY TRACT 2, L01'S l AND 2 (REVI +1"12-98) August 27, 1998 Findings: The City of Everett Planning Department rcceived an application from you to ailow a Stap Slope Duffer Rcduction for the stecp slope along the west side of the Seaway Tract 2, Lots I and 2 property. The rcquest is to al�ow pazking and driveways to bc provided in the rcquired 25 foot buf(er. Section 37.080.0 of the Zoning Code �nd Ordinance No. ? 136-96 allow the Planning Director ta authoriu a alteretion o(the standard buffers listed in ihe Zoning Code if a georechnical report is approved which demonstrates thar. . The proposed development will not create a hazard to the subject property, suRounding properties or righu-of- way, erosion or sedimentation to off•site properties or bodies of water; and • The proposal addresses the existing geological constreints uf the site, including an assessment of soils and hydrology;and • The proposed method o(construction will reduce erosion potential, landslide and seismic hazard potential, and will improve or not adversely affect the stability of slopes; and . The pro�osal uses construction techniques which minimize disruption of existing topography and natural vegetation; and • The proposal is consistent with the purposes and provisions of this Ordinance; and . The proposal mitiga�es all impacts identified in the geotechnical repon; and • All utilities and access roads or driveways to and within the site will be located so as to require the minimum amount of modifi uion to slopes, vegetation or geologically hazardous areas. The site has been mined under DNR mining pertnits. The slope was created through the mining operation. Vegetation consisting of alder and maple trees and brush currently exists on the slope. Lit:le, if any vege[ation erists within the required 25 foot bulTer at the toe of the slope. Additional grading is occurting on the site to add approximately I-I/Z ro 2 feet uf fill ta the site. A georechnical repon was completed for �he site by Earth Consultants, Inc., dated July 16, 1998. The report stares that some indications of past instability exist, including debris ilow scarps and chutes and indications of downslope creep in the vegetation. However, none o(ihese fea[ures appears to be recent or active. Fill that was placed at the toe of the slope in 1996 should buttress the tce of the slope and mitigate the creep porentiaL (The additional I-1/2 to 2 feet of fill from the currcnt grading should also help buttress the tce af the slope.) The report s[ates that Earth Consultants belicves it is fcasible to extend pavement to the roe of the slope. Buildings should maintain a utback of 25 fcet. Conclusions: The buffer has bcen highly modified through mining activiry on the site. The fill being placed on the si[e will increase the stability of the slope. Based upon Earth Consul�ants conclusions, the provisian of parking and driving areas will not advcrsely affcct the stabil�ty of the slope. Buildings should be setback a minimum of 25 fect from the toe of the slope. ! 9j !2� G�
