The following is a summary of the <br /> results in the two phases of the subdivision. <br /> Phase I - Which currently has 13 connections plus 1 under construction: <br /> Out of 7 soil borings - All 7 borings could be classified Provisionally <br /> Suitable and ranged from 24 to 32 inch soil depth before <br /> encountering unsuitable horizons consisting of saprolite or <br /> in the case of two holes [ in the 12-16 subfields ] , massive <br /> clay . It should be noted that while these borings <br /> indicated a Provisionally Suitable classification, we would <br /> express concern over a large capacity system such as this <br /> installed in these marginal site conditions . We also <br /> recognize from earlier evaluations that the soil depth <br /> within Phase I can be quite variable. <br /> Phase II - Which has 20 connections: <br /> 5 borings in Field A - None were classified as Suitable or <br /> Provisionally Suitable . All borings were classified <br /> Unsuitable due to one or more of the following factors : <br /> -Topography/ landscape positions containing convergent valley <br /> slopes , gullies , and/or terraces . <br /> -Soils which are massive , exhibiting no structural peds , less <br /> than 24 inches from the ground surface . <br /> -Expansive clay mineralogy. <br /> SOUTHERN ORANGE OFFICE.
