The home will be served by a private well and septic system. We are proposing to install a 1,000 gallon septic tank and a 5 wide trench type drainfield. One testhole was excavated on the property by Steve Pannone, P.E. in December 2014. The drainfield is designed around the 30 foot radius of this testhole. '1. SOILS: See the attached soil log from Steve Pannone, P.E. dated 2014 which shows the soil classifications, groundwater monitoring, and the percolation test results. 2. DRAINFIELD DESIGN: See attached design drawing for drainfield specifications. 3. SURFACE WATERS: There are no surface water concerns. 4. TOPOGRAPHY: As can be seen on the attached topography drawing, the average topography around the proposed drainfield is 30% running northeast to southwest. 5. WAIVER REQUEST: We are requesting a 0 foot waiver be granted from the proposed drainfield (including reserve site) to slopes greater than 25%. We are also requesting your department issue a variance to allow for the slopes below the drainfield to be 3:1 (33%) or less. As can be seen on the attached drawing (page 3 of 3), at a 25% slope (starting ~2.5 feet above the drainfield) the potential point of daylighting is greater than 50 feet horizontally from the drainfield. Your department also accepts slopes of 3:1 for any drainfield that is above grade (mounded) We are unaware of an systems. If you adverse impacts this installation or waiver would have on adjacent wells or septic any questions, please contact us at 337-6179. Thank you for your assistance.
