Re: 805 Johnson Street(Map 107A, Lot 67)
Dear Mr. Osgood:
The proposed wastewater system design plan for the above site dated May 4, 2022 has been
reviewed. Unfortunately,the plan cannot be approved until the following items are corrected.
The specific section in Title 5: 310 CMR 15.000, or North Andover regulation that is not met by
this design follows each item where applicable.
1. Construction Note#1 references a type of onsite wastewater system product and retention
of the B soil horizon not proposed elsewhere on the design plan. Clarify this discrepancy
2. Provide a statement identifying whether the property is within or not within the Lake
Cochichwick watershed(NA 3.2).
3. If one extrapolates the ground water table in the rear yard based on to that found in the
front yard it appears the tank pipe penetrations are less than 12"above the water table and
that buoyancy calculations are required. Address these issues or explain what the water
table depth is in the rear yard(15.221 & 227)
4. General Note#4 appears to conflict with the benchmark which is provided on the site
plan. Clarify this discrepancy
5. If the design plan is going to require an effluent filter then provide for a manhole cover to
finished grade over the effluent filter and a note indicating the need for annual
maintenance(15. 227)
6. Show an inspection port on the Site Plan in addition to the one shown on the System
Profile (15.240)
