Box 66 <br /> Orono, MN 55356 Crystal Bay, MN 55323-0066 <br /> May 3, 2000 <br /> Frederick Puzak <br /> 1340 Baldur Park Road <br /> Wayzata, Mn 55391 <br /> Dear Mr. Puzak: <br /> This is a follow up letter regarding the septic maintenance inspection conducted on Apri127, 2000. <br /> It was found during the inspection thax the septic tanks are un.dersized according to cunent Orono <br /> City Code. A septic system must utilize two septic tanks and each septic ta.nk must be a minimum <br /> of 1000 gallons. It also appeared that the drainfield(s) are undersized and would not meet today's <br /> standazds for drainfield sizing. Finally, the septic system is in the 75 foot setback to Lake <br /> Minnetonka. According to City code, nothing is to be constructed within 75 feet of Lake <br /> Minnetonka. e <br /> Now, with a11 that said,there is a definite upside. A soil boring was conducted which indicated that <br /> the seasonal watertable will be at least 70 inches below grade. It could even be deeper but this is <br /> undetermined due to the fact that I hit a rock. The dra.infield is about 44 inches deep thus there is <br /> a separation of at least 26 inches from the drainfield to the seasonal watertable. I was incorrect <br /> when I informed you that a 24 inch sepa.ration is required. Any property located in the Shoreland <br /> District(any property within 1000 feet of any lake)must meet the three foot separation requirement <br /> regardless of when the septic system was installed. I apologize for any confusion this may have <br /> caused. <br /> Because there appeazs to be substantial separation to the seasonal watertable,connection to the City <br /> sewer system does not need to happen immediately. The septic systems can continue to serve the <br /> residence as long as there are no changes to the residence that would require the septic systems to <br /> be enlarged to handle the additional capacity. An example ofthis would be a bedroom addition. The <br /> existing septic systems cannot be altered(i.e.,made bigger)due to the fact that they do not meet the <br /> 75 foot setback to Lake Minnetonka. If major changes are to occur to the residence, connection to <br /> the city sewer system would be the only acceptable altemative. I am aware of the issues regarding <br /> your ability to connect to sewer. <br /> Telephone(952)249-4600 • Fax(952)249-4616 <br /> www.ci.orono.mn.us <br />
