'1'he tunnel is adjacent to the m-�,i <br />garage. These tunnel drains are b�sically emergency drains that wi11 <br />pick up �vater very infrequently - only if sprinkler discharges in the <br />tunnel or if the tunnel is hosed down. We have a drainage pipe in cl.osc <br />prosimity to the tunnel that is picking up the tunnel underfloor <br />draina9e system (designed as part of the civil documents). This pipe <br />connects to area drains in bottom level of the garage and routes through <br />a grey water sump pump in lowest level of the garage (also designed b, <br />civil). {9e are proposing to connect the floor drains in the tunnel to <br />this pipe and route these drains thro�gh the sump pump. The floor <br />drains in the tunnel will be trapped, primed and vented. 8ased on ou: <br />.iiscussion, we understand that connecting these drains to the greywater <br />:��.unp pump is acceptable to the city of Everett. We will proceed <br />:�-cordingly. <br />.: you have any questions, please do not hesitate to contact our office. <br />'�. also reeeived a call form Paul Mekce �:�;th thc ci[v.
