STEEP SLOPE BUFFER REDUCTION SEAWAY TRACT 2, LOTS 1 AND 2 (REVI N22-98) August 27, I99N Findings: The City of Everctt Planning Depanment received an application from you to allow a Steep Slope Bu(fer Reduction for the steep slope along the west side of ihe Seaway Tract 2, Lms I and 2 property. The request is to allow parking and driveways to be provided in thc required 25 (oot bufTer. Section 37.080.0 of the Zoning Code and Ordinance No. 2136-96 allow the Planning Director to authoriu a alteration of [he standard bufTers listed in the Zoning Codc i(a geotechnical report is approved which demonstrates �hat: • Thc propased development will not create a hazard to the subjcct property, surtounding properties or rights-of- way, erosion or sedimentation to off-site properties or bodies of watcr; and • 7he proposal addresses the existing geological constraints of ihe site, including an assessment of soils and hydrology;and . The proposed method of construction µ�ill reduce erosion pmential, landslidc and seismic hazard potential, and will improve or not adversely af%ct the stability of slopes; and • The proposal uses construction techniques which minimizc disruption of'existing topography and natural vegetation: and . The proposal is consistent with the purposes and provisions of this Ordinance; and • The proposal mitigates all impacts identified in the geotechnical report: and • All utilitics and access roads or driveways to and within the site will be locatcd so as to require the minimum amount of modification to slopes, vegetation or geologically ha7ardous areas. The sitc has bcen mined under DNR mining permits. Thc slope was crcared through the mining operation. Vegetation consisting of alder and maple trees and brush currently exists on the slope. Little, if any vegetation c�ists within thc reyuired 25 foot buffer at thc toe of the slope. Additional grading is occurring on the site to add approsimatelp I-U2 ro 2 feet of fill to thc site. A gwtechnical repon was complelcd for the sile by Eanh Consultants, Inc., dated July 16, 1998. The report stares that some indicalions of past instabiliry exist, including debris Oow scatps and chures and indications of downslope crecp in �he vegetation. However, none of these fcatures appears to be recent or active. Fill that was placed at the toc of the slope in 1996 shoulJ bunress the toc of the slope and mitigate the creep potential. (Tlic additional I-1/2 to 2 fec� of fill from the current grading should also hclp buttress the toe of ihe slopeJ The report states that Earth Consultants bclievcs it is f'casible to extend pavemcnt to the toe of the slope. Buildings should maintain a setback of 25 (cet. Conclusions: The bul7cr has bcen highly modified through mining activity on ihe site. The fill being placed on the site will increase the stabiliry of the slope. Based upon Eanh Consultants conclusions, the provision of parking and driving arcas will not advcrsely affect thc stability of the slope. f3uildings should be setback a minimum of 25 feet trom the mc o(the slope.
