To: Street File - 2845 Watertown Road <br /> From: Chris Pence, On-Site Systems Manager <br /> Subject: Septic Sites <br /> Date: May 30, 2000 <br /> A site inspection was conducted at the above stated property on May 26, 2000. The inspection was <br /> conducted to determine compliance of the septic system. A soil boring was conducted. Mottled <br /> soils (sign of seasonally high watertable) were found at 48". The bottom of the trench was found <br /> to be at 14". The separation required for a system built prior to April 1, 1996 and not located in the <br /> shoreland district is 24". The existing septic system has 34" of separation, making the drai dield <br /> compliant. The tanks were probed and found to have solid concrete bottoms. <br /> The setback from a deep well to the septic tanks and the drai dield area is 50 feet. The existing well <br /> is 43 feet from the septic tanks and over 60 feet to the drainfield. According to a conversation with <br /> staff from the Minnesota Department of Health (MDH), any well installed prior to 1989 is not <br /> required to meet the 50-foot setback to existing septic tanks or drai dields. It is only recommended <br /> that the well or septic system be moved to meet the 50-foot setback. Therefore, the well does not <br /> need to be moved to meet the 50-foot setback. <br /> There is not an alternate septic site designated for the property. City code requires that an alternate <br /> septic site be approved by the City before a building permit is issued. <br /> Due to the fact that the septic tanks could not be inspected properly, the tanks will need to be <br /> pumped through the manhole and integrity of the tanks will need to be noted. The tanks will need <br /> to be inspected by City staff prior to covering the tanks. This tank inspection must be done prior to <br /> any building permits being issued. <br /> In summary, the existing well and septic system can be used. The new house can be no larger than <br /> four bedrooms. Prior to any building permits being issued,an alternate septic site must be approved <br /> by the City and the septic tanks must be pumped and inspected for integrity. <br /> cc.
