(Link to Metadata) ONSITE is a pre-selected subset of SSURGO certified soil data depicting onsite sewage disposal ratings of Vermont soils. The NRCS Top20 table was joined to SSURGO polygons. The joined data set was then DISSOLVED on the ONSITE attribute in order to merge polygons with the same ONSITE classification code. VCGI HAS NOT PERFORMED QAQC ON THE RESULTS. AS A RESULT, THIS DATASET SHOULD BE USED WITH CAUTION. NOTICE: This information identifies the new onsite sewage disposal class. This new system replaces the old classification system. Ratings are based on Vermont Environmental Protection Rules, August 16, 2002, based on 20% maximum slope - for lots created on or after June 14, 2002. It doesn't replace onsite investigation. These are the five major classes. Class I - WELL SUITED Class II - MODERATELY SUITED Class III - MARGINALLY SUITED Class IV - NOT SUITED Class V - NOT RATED Refer to documentation bundled with the SOILATTR product--AKA VT DATA - NRCS TOP20 SOILS ATTRIBUTES AND DOCUMENTATION (which is a stand-alone item in Vermont Open Geodata Portal); SOILATTR can be directly downloaded via https://drive.google.com/uc?export=download&id=13a68oimr0sVu_D4jXrNKAMNBIbVE9GN7 .
