| JSON | SOAP |
Quarter-mile Buffer built from a composite of NH Designated Rivers from the following NHGS 2022 shapefiles: NHDFlowline, NHDArea, and NHDWaterbody, plus NHDES' Floodplain100Yr_Dissolve shapefile. Created specifically to support the Rivers & Lakes Program's NH Designated River Corridors Web Map.
Includes the following fields:
OBJECTID: Unique, sequential, numeric identification code, auto-generated by ArcGIS software (read only).
Shape: Code defining the shape type (Polygon), auto-generated by ArcGIS software (read only).
Shape_Length: Shape length, auto-generated by ArcGIS software (units uncertain).
Shape_Area: Shape length, auto-generated by ArcGIS software (units uncertain).
RIVERNAME: The name of the designated river, including designated tributaries and branches, as listed in RSA 483:15.
RSAREF: The RSA 483:15 reference that describes the designated river section.
CLASS: One of four designated river classes defined in RSA 483:7-a. Classes are limited to: Natural, Rural, Rural-Community, and Community.
STRMORDR: Stream order as defined by NHGS’ 2013 NHDStreamOrder shapefile. Included only for two designated rivers (Lamprey and Oyster Rivers) where Comprehensive Shoreland Protection Act protections are not extended to designated river segments below 4th Order per RSA 483-B:4(XV). Classes are limited to: 3- (3rd Order of less), 4+ (4th Order or greater)
RIVERSECT: Sequential, numerical identifier for each Class segment of each designated river listed in RSA 483:15, based on its position along the river starting from the upstream end. Designated tributaries and branches of designated rivers are sequentially-numbered separately.
LAC: Name of the Local Advisory Committee, and for the Connecticut River, the subcommittee, established for the designated river in accordance with RSA 483:8-a.
SWQPAEXMPT: Indicates whether or not the designated river section comprising 1st through 3rd Order streams is exempted from protection under the Surface Water Quality Protection Act normally reserved for 4th Order streams and greater.
Fact_Sheet: Includes a link to the NHDES' Rivers & Lakes Program Fact Sheet for the designated river.
Contact_In: Includes a link to the web page for the designated river's Local Advisory Committee that is maintained by NHDES' Rivers & lakes Program, which includes contact information for the LAC.
