We recommend further subsurface expluration and possibly infiltration testing be <br /> performed in specific areas targeted fur storm water infilvation, if it is coasidered as a <br /> design option based on review of this report. The Ciry of Everett will require textural <br /> � characterization of soils at the design infiltraaon elevation(s) at a minimum. <br /> • 11'e aze available t� provide specific wall design criteria to help stabilize the steep <br /> � a�estern slope upon request. <br /> � We are �lso available to provide geotechnicai engineering and monitoring services during <br /> conscructioo. The integriry of the foundations depends on proper site preparation and <br /> construction procedures. In addition, engineering decisions may have to be made in the field <br /> � in the evenc that variatioas in subsurface conditions become ap�arent. Coastruction monitoring <br /> services aze not part of this current scope of work. If these services aze desired, please�let us <br /> }:now and we will prepare a cost proposal. <br /> � We have enjoyed working with you on this study and are confident that these recommendatioas <br /> will aid i❑ the successful completion of your project.
