Crewdson, PE Subject: Chugach Park Estates, Block 2, Lot 17 Septic System Design Revision Number of Pages: 3 Jay, During the 1st inspection, it was discovered that excessive clean gravel was present in the trench lower 3 feet. We are submitting the following revision which was coordinated by MOA field representative Jeff Poet. The maximum depth is 4.5 feet which will place the absorption field in the sandier soil strata. The new trench length was calculated ~ Trench Length = 375 FT2/5 'x .7 reduction factor = 52.5'; 1 line ~ 53'. Please issue the approval of the revised design.
