RE: Lot 1 Septic Design for the Olyview Subdivision (Parcel 22121-21-90011) in
Mason County, Washington
Dear Mr. Hamar,
Envirotech Engineering (Envirotech) has completed an update of the previously
designed on-site septic system for Lot 1 in the Olyview subdivision in Mason County,
Washington.
The original septic designs were completed by Envirotech for Mr. Rick Leffler, and were
approved by Mason County under permit SWG 2007-00604. An update of this septic
design was completed by Envirotech for Anchor Bank, permit SWG 2010-00197. The
enclosed design, updated again, was unaltered except for providing the most current
Mason County Design Form, and current engineer's stamp. The on-site septic design
meets all current applicable codes and standards.
If you have any questions or need any further assistance, please contact Michael Staten
at 360-275-9374.
Sincerely,
Envirotech Engineering
