Re: Bayside Meadows Proposed Plat
I have reviewed the preliminary septic system designs for the 5 proposed lots in Bayside Meadows
Addition. The designs show two standard septic sites for each lot with a proposed house site. Lots 2-5
would allow some flexibility in final house location. Lot 1 does not allow for any flexibility and should be
noted as such. The septic sites split much of the lot and along with the wetland limits the house site to
basically where it is proposed.
I have stamped approvals for the five proposed sites. If you have further questions please let me know.

Proposed Lot 2
Orono,Hennepin.County
This on-site Sewage Treatment System is partially designed for a Type 1,five-bedroom home in
accordance with the Minnesota Pollution Control Agency Chapter 7080 and local ordinances.
Once the house size, location and septic primary and future sites are chosen this desigr►can be completed.
The periodically saturated soils were located at 16-18 lnches(mottled soil). Due to the periodically
saturated soils,a pressurized mound system will need to be installed to treat the septic effluent.The bottom
of the treatment area must be located at least 3' above the saturated soils.
The soils at a depth of l2"have a percolation rate averaging 6.5 MPI.
The absorption areas do not overlap.
All tanks need to be insulated if there is less than two feet of cover over the top of the tanks.A fi Iter needs
to be installed on the second tank.Clean outs must be installed on the end of the laterals for maintenance.
A pumping chamber will need to be installed to lift the effluent to the treatment area.The power supply and
switches must be located outside the manhole and pumping chamber in a weatherproof enclosure.A
warning device must be installed with a light and sound device;this is in case of a pump failure.
Use 7/32 inch perforations on the laterals.
Keep all heavy eyuipment off of t6e proposed treatment areas before and after construction.The
treatment area must be fenced off before construction begins.This Design is not valid &the System
will need to be relocated if failure to protect the areas proposed for the On-Site Sewage Treatment
systems occurs.
Nothing other than gray water,(laundry,showers,ect.)human water&toilet rissue should be disposed of
into the septic tanks. Garbage disposals are not recommended.Additives must not be used;they may cause
harmful damage to your septic system. It is recommended that you pump the septic tank every year for 1
tank,every two years for two tanks.

Note:Mound setbocks are measured from the Absorption Area.
A. Calculate Absorption Width:Bed Width (2.6)X Mound Absorption Ratio (1.F)=Absorption Width
10.0 ft x 2.6 = 26.0 ft
B. For slopes>1%, the Absorption Width is measured downhilt from the upslope edge of the Bed.
Calculate Downslope Abwrption Width:Absorption Width (3.A)-Bed Width (2.6)=ft
26.0 ft - 10.0 ft = 16.0 ft
