������ ��t s��, ��. _ <br /> 10�6- 74TH STREET <br /> EVERETT,WASHINGTON 98201�1691 <br /> TELEPHONE (206) 259-0137 <br /> � (206) 743-7530 <br /> (206� 258-2298 FAX <br /> P'roposal <br /> Fishermen's Boat Sliop,Ine. and the Pon, :nverett(collec:tively"FBS")propose to drain <br /> approximately 20,000 square feet of srorm water discharge io City of Everett(Ciryj sewer <br /> system. <br /> Assumntiun�;. <br /> The City has designed and built a storm water and sewer system to handle a certain size <br /> storm event("event"). During such an event, the system reaches capacity. During diese <br /> "events", the City cannot accept additional water. At umes when p�cip:tauon is less than <br /> an event, the City has excess capacity and is able to accept addiuonal water into the system <br /> without overloading the system. <br /> $Satistics: <br /> . Arca to Drain: 20,000 square feet (approx.) <br /> . Maaimum Event 2" rain in 24 hours <br /> . Water Created During an Event 26,000 gallons <br /> Pro.posal Specifics: <br /> FBS will buiy a properly sized tank and create an above ground retenuon area("retendon <br /> system") to retain storm water such that during an event a limit switch will automatically <br /> stop the outflow of water from our retention system. This will assure that no storm water <br /> will enter the Ciry systcm during an event. As an example,given the above assumptions, <br /> FBS will bury a 5,000 gal�on tank and create a 26,000 gallon above ground pond. 'fhis <br /> will allow for a 20% safet�,r factor while meeung the requirement for no added water to the <br /> systcm during an evenG <br /> The retenuon system will be professionally eegineercd to meet Ciry reyuirements. The <br /> attachment is a rough draft drawing meant to i;lustrate how the retenuon system will work. <br /> 8 May 1997 <br /> MARINE REPAIR, CONSTRUCTION,CONVERSIOM 8 MAINTENANCE IN STEEL.
