To: Jeanne A. Mabusth, Building & Zoning Administrator From: Steve Weckman, Septic Inspector Date: July 3, 1991 Subject: Mark Johnson Subdivision, 4455 Bayside Road -Review of septic system information A. Proposed Lot 2 The primary drainfield site has been tested in the southeast corner of the lot. This site is acceptable for a mound with an average perk rate of 15.6 minutes per inch and a slope of 5%. The lot line setbacks for this site are 25' from the east lot line and 50 1 from the south lot line, and over 75' from the wetland on the property to the south of this lot. The alternate site is located north of the primary site adjacent to Bayside Road. This site is suitable for a mound system, having a slope of 4% and an average perk rate of 20.6 minutes per inch. The setback from Bayside Road is 20' while the setback from the pond to the west is 7 5'. The mound should meet the required setbacks, however, space is very limited on this site. Several trees may need to be removed when this site is used. Both sites are suitable for a mound systems serving a 4- bedroom home. These sites should be fenced off prior to construction to prevent compaction from heavy machinery. The eastern lot line should also be clearly marked to assure that the required 20' setbacks are met. B. Proposed Lot 1 The existing house on proposed Lot 1 has a septic system that is failing as noted on a recent inspection. The system consists of one concrete tank of unknown size and construction and a tile which surfaces in the wetland in the southeastern corner of the lot. This lot will require soil testing and design for a complete septic system and an additional drainfield site for future expansion. The existing septic tank wi 11 need to be inspected to determine whether it can be used in the new system. Soil boring, percolation tests, and septic design must be approved by the City in order to complete the requirements for the subdivision. lsv l
