To mitigatc <br /> such hazard, thc vegetation covcr outsidc of constniction limits shoidd bc preserved and <br /> maintained, and conccntratcd storniwater should not be discharged uncontrolled onto the stecp <br /> slopc or anywhcrc within thc sitc. Stomi runoff ovcr impervious surfaccs, such as roofs and <br /> pavcd driveway should hc capturcd with undcrground drain linc systcros ticd to roof downspouts <br /> and by catch basins installcd in pavcd drive�vay. Watcr collccted in�o thesc underground drain <br /> lincs should bc tightlincd to dischargc into a ncarby storni sc���cr. Yard wastc and spoil soils <br /> should not disposcd ofonto thc stccp slorc. Gxposcd unpavcd ground resultcd Gom conslruction <br /> activitics should bc rc-vcgctatcd as soon as possiUlc. If thc abovc rccommcndations arc <br /> implcmcnted and obscrvcd during and a(icr construction, thc crosion hazard of thc sitc should bc <br /> minimal. <br /> SEIS�'lIC IIA'l,ARU AND UESIGN CONSIUERr�T10NS <br /> 'I'hc Pugct Sound region is in an aclivc scismic ronc.
