this design follows each item where applicable.
1. Magnetic marking tape is required over the onsite wastewater system(15.221)

3. A 5' overdig is to be provided around the soil absorption system(15.255)
4. Indicate the leach pipe perforation size
5. The note and graphic adjacent to the Scaled Profile are not clear as to what they are
depicting
6. The water table should be elevation 90.9 as the basis of the design
7. The offset from the water table to the bottom of the soil absorption system is not 4' as
indicated in the Scaled Profile
