Process Description:
The original sole-source aquifer coverage was created using ARC/INFO ARCEDIT (ver. 7.0.1) running on a Sun SPARC20 workstation. The coverage was built by first copying the N.J. State boundary lines from the stmun into a new coverage saved as ssa. Arcs representing the boundaries for each SSA project review area were then appended to the new coverage by copying arcs from, or generating new arcs based on, the three source coverages. Coverage development proceeded in the following manner. 1) Coastal Plain - Arc segments composing the northwest continuous contact of the prma aquifer from the baqfr250 coverage were manually selected and appended to the sole-source data, and intersected with arcs for the State boundary and Coastal Plain SSA. Arc segments corresponding to boundaries of HUC11 polygons with label values of 02030105070, 02030105080, 02030105100, 02030105110, were then selected, appended to ssa, and intersected with arcs for the State boundary, the Coastal Plain SSA, and the previous set of HUC8 arcs. All remaining arcs within the resulting polygon were deleted. 3) Highlands - Arc segments corresponding to boundaries of HUC11 polygons with label values of 02030103050 and 02030103070 were selected, appended to ssa, and intersected with arcs for the State boundary and the Northwest New Jersey SSA. Extraneous arc segments were deleted. 4) Ramapo - Arc segments corresponding to the boundary of the HUC11 polygon with a label value of 02030103100 were selected, appended to ssa, and intersected with arcs for the State boundary and the Highlands SSA. Extraneous arc segments were deleted. 5) Ridgewood - Arc segments corresponding to the boundary for the HUC11 polygon with a label value of 02030103140 were selected, appended to ssa, and intersected with arcs for the State boundary and the Ramapo SSA. Arc segments corresponding to the boundaries of polygons from the stmun coverage with Mun labels for Wyckoff Twp., Ridgewood Village, and Glen Rock Boro were then selected, appended to ssa, and intersected with the HUC11 boundary. Arc segments corresponding to the boundary of the HUC14 polygon with a label value of 02030103140040 were then selected, appended to ssa, and intersected with arcs for the HUC11 polygon and Ridgewood Village. All remaining arcs within the resulting polygon were deleted. 6) Rockaway - Arc segments corresponding to boundaries of HUC11 polygons with label values of 02030103020, 02030103030, and 02030103040 were selected, appended to ssa, and intersected with arcs for the Northwest New Jersey and Highlands SSAs. Arc segments corresponding to the boundary for the polygon from the stmun coverage with Mun label for Montville Twp were then selected, appended to ssa, and intersected with the HUC11 boundary. All remaining arcs within the resulting polygon were deleted. 7) Buried Valley - Arc segments corresponding to the boundaries of HUC11 polygons with label values of 02030103010 and 02030103040 were selected, appended to ssa, and intersected with arcs for the Northwest New Jersey and Rockaway SSAs. Arc segments corresponding to the boundaries of polygons from the stmun coverage with Mun labels for Bernards Twp, Warren Twp, Berkeley Heights Twp, Summit City, Millburn Twp, Fairfield Boro, and North Caldwell Boro were then selected, appended to ssa, and intersected with the HUC11 boundaries. All remaining arcs within the resulting polygon were deleted. The sole-source data was cleaned and built using default program values for dangle length (10,000.000 ft) and fuzzy tolerance (0.183 ft). A new polygon item (ssaname) was added to the coverage polygon attribute table for specifying the name of each SSA. SSA names were manually added. *Physiographic province boundaries needed for sole-source aquifer area delineation were extracted from correlative aquifer boundaries. The coverage was exported to a shapefile.
