PUBLIC WORKS <br /> 1.41hlt <br /> "s* <br /> March 28, 2012 <br /> Mr. Jerry Murphy <br /> 621 Legion Drive <br /> Everett, WA 98201 <br /> Re: Backwater Valve Program for property at 621 Legion Drive <br /> Dear Mr. Murphy: <br /> The City of Everett's contractor, Seattle Drain Services, inspected your property on <br /> January 12th, 2012 to determine if a backwater valve is appropriate for your residence. <br /> Enclosed is a summary of their findings. <br /> The report does not recommend installing a backwater valve on the side sewer that <br /> connects your home to the City's sewer main to reduce the risk of basement flooding <br /> until after the slope of the side sewer is increased. Currently the side sewer serving the <br /> property at 621 Legion Drive has only approximately 0.5% slope. City design and <br /> construction standards require that side sewers have a minimum of 2% slope. Also <br /> backwater valve manufacturers specify that the side sewer must have a minimum of 1% <br /> or 2% slope adjacent to the backwater valve for the valve to work properly. Please <br /> review the report and contact us with any questions. <br /> The report identifies several deficiencies in your plumbing, sewer, and drainage system. <br /> These include: <br /> • There is no backwater valve or grinder pump to protect the building from a <br /> surcharge <br /> • The side sewer slope is approximately 0.5% <br /> • Downspouts are connected to the sewer system which increases flow in the <br /> sewer during surcharge events. <br /> Due to the current condition of the side sewer at this address this property is not <br /> currently eligible for a backwater valve through the City's backwater valve program. <br /> Additionally, storm damages related to private system deficiencies identified in the <br /> inspection report or any other private system deficiencies are the responsibility of the <br /> property owner. We therefore recommend that you take steps to correct these <br /> problems, and that you regularly inspect your plumbing, sewer and drainage systems to <br /> ensure they are working correctly and efficiently. <br /> CITY OF EVERETT • 3200 Cedar Street • Everett, WA 98201 • (425) 257-8800 • Fax (425) 257-8882 <br />
