Burlington, Vermont Re: Harry Yawney property Sanitary design Dear Dick: Administrator 05401 CONSULTANTS 295 SHUN PIKE ROAD SO. BURLINGTON, VERMONT 864-0777 Pursuant to your request, I conducted additional percolation tests on the Yawney property. I am submitting attached the revised sanitary design based upon the results of those tests. The percolation tests took two days to complete. I started the tests on June 3, and completed them on June 4. The results of the tests are tabulated on the attached plan. Incidently, it rained the night of June 3. The design of the system is based upon Agency of Envir- onmental Conservation guidelines for single-family residences. If you have any questions concerning the system, please feel free to call. Very truly yours, Richard M. Doherty RMD/m enclosures N 7 Sul �-- SHELeQW4I: SOIL Q.TA TeST PIT" PROFILE S 0-6 TOPSOIL._ 6 " - 30" C L.qY W " - 34 ' M U T T i_.
