TO: Mayor Callahan and Orono Council Members Ron Moorse, City Administrator FROM: Michael P. Gaffron, Asst. Planning & Zoning Administrator DATE: July 7, 1993 SUBJECT: 2700 White Oak Circle - Septic System List of Exhibits A - Inspection Report and Soil Boring Log 5/28/93 B - Septic System Inventory Card C - Inspection Reports 7/25/91, 6/16/88, 8/14/84, 7/30/79, 8/22/78 D - System Design Report 1976/78 E - Letter to Owner Jason Becker 1/28/79 Sununary of Procedure/Conditions Encountered This system was inspected May 28th apparently at the request of the intended buyer or his lender who required a septic certification. Steve Weckman indicates that whether or not the inspection had been requested, this property would have been inspected later this summer as part of the regular program. Weckman's boring found that the existing trench system has a seasonal water table separation ranging 1" to 3" as identified by soil mottling and gleying, as well as noting an actual free water surface 1' below the trenches on the day of the boring. The system is clearly nonconforming by the definition adopted as part of our septic code revision in February 1992. The soil boring log indicates that borings were taken at the uphill side of the system, which would likely yield the most favorable conditions at the site. It would not be surprising to find no separation between the most downhill trench and the seasonal water table. In my opinion, Weckman correctly defined this system as nonconforming, and the inspection report indicated that the system must be upgraded within one year, as required by City ordinance for all nonconforming systems since 1978. Addressing Specific Points Made by Rasmussen's Attorney • System installed under 1978 code standards This system was installed in 1978 by Westonka Plumbing. Actual soil testing for this site had been completed for VanEeckhout Building Corporation by Soil Testing Services of Minnesota in December 1976 as part of the subdivision to create White Oak Circle. The design was done by Mr. VanEeckhout and approved by the City in April 1978. The system was installed in August 1978.
