Y ~ `\ •- • City of ,~~ MEMORANDUM ~lk 1 ~ TO: Pat Klaers River FROM: Steve Rohlf, Building and Zoning Administrator DATE: June 27, 1995 Cj~ SUBJECT: Soil Borings on Cass Property Soil borings to determine water table, mottled soil, and soil composition were completed on the Cass property by Independent Testing on June 27, 1995. The borings for the eight lots proposed indicated that there was 5+ feet from the surface of the ground to mottling and/or water table, with the exception of boring #8. It is my opinion that the proposed north seven parcels would be suitable for building with at least an acre of property, a min;mum of three feet above water table.. The eighth lot (the 14 acre parcel) could accommodate a slab on grade home, unless it can be demonstrated that another design works. I recommend that potential buyers of these lots be provided with the attached soil boring data. It will be up to the buyers of each of these lots to provide the city with an additional soil boring and perc test at the time of building permit application, to demonstrate a proper design for their septic system. I recommend that homes built on these lots have their lowest floor a ;n;mum of one foot above mottled soil and/or water table. The suitability of the type of home proposed on a lot would be considered at the time of building permit application. Two soil samples were taken on the land we propose to dispose sludge on. They were taken above the swamps on this property, but still in the low areas. One boring showed three feet from water table and the other approximately sixteen inches. Staff still feels there will be roughly twenty acres of higher land adjacent to these borings that can be used for sludge disposal, if a small wetland can be filled and mitigated. • sr6-27Jbzlstever 13065 Orono Parkway • P.O.
