Dear Ms. Schmitt:
Enclosed is a copy of Mr. Speck's application data for site conditions on Lot 3 of the
proposed=Speck7Subdivision., This site information supports the possible installation of
a septic tank with an effluent collection tank and pump to serve a mound or fill system
located in the NE corner of the useable area of Lot 3. 1 have enclosed an example
diagram of what a mound or fill system consists of. This was also supplied to Mr. Speck.
The area need for this system can be found aside from the defined sewer easement from
Lot 2 and still allow for a well placement in the front area of the Lot. r
At this time, I see no concerns which would prohibit the proposed development on Lot 3.
If there are any questions over any concerns with regard to on-site facilities, please
contact me directly.
Sincerely,,
Doh Noltin , R.S.
