Abstract:

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 .

Purpose:

Provide a pre-selected layer depicting onsite sewage disposal classification of Vermont soils.
This data depicts information about the kinds and distribution of soils on the landscape. The soil map and data used in the SSURGO product were prepared by soil scientists as part of the National Cooperative Soil Survey.

Supplemental_Information:

Digital versions of hydrography, cultural features, and other associated layers that are not part of the SSURGO data set may be available from the primary organization listed in the Point of Contact.

Use_Constraints:

The U.S. Department of Agriculture, Natural Resources Conservation Service, should be acknowledged as the data source in products derived from these data.
This data set is not designed for use as a primary regulatory tool in permitting or citing decisions, but may be used as a reference source. This is public information and may be interpreted by organizations, agencies, units of government, or others based on needs; however, they are responsible for the appropriate application. Federal, State, or local regulatory bodies are not to reassign to the Natural Resources Conservation Service any authority for the decisions that they make. The Natural Resources Conservation Service will not perform any evaluations of these maps for purposes related solely to State or local regulatory programs.
Photographic or digital enlargement of these maps to scales greater than at which they were originally mapped can cause misinterpretation of the data. If enlarged, maps do not show the small areas of contrasting soils that could have been shown at a larger scale. The depicted soil boundaries, interpretations, and analysis derived from them do not eliminate the need for onsite sampling, testing, and detailed study of specific sites for intensive uses. Thus, these data and their interpretations are intended for planning purposes only. Digital data files are periodically updated. Files are dated, and users are responsible for obtaining the latest version of the data.

Process_Description:

SSURGO county soil data was joined to May 2003 Top20_vt.dbf attribute table. Joined data was DISSOLVED on the ONSITE attribute to create contigous polygons with the same ONSITE rating. Documented problem with non-matching MUIDs in Chittenden County (ONSITE07), resulting in null ONSITE ratings. Metadata was created and the data was loaded into the VGIS Data Warehouse.
