What's the Difference Between B-1 and B-2 Commercial Zoning? (More information than you really wanted...)

The following has been excerpted from the New Hanover County Zoning regulations. The Lowe’s parcel is currently B-1 with a B-2 rezoning request; the 50 acres behind this and behind the Porters Neck Shopping Center is B-1 currently.
Section 54: B-1 Business District
54-1: The purpose of this District shall be to provide convenient shopping facilities primarily of necessity goods and personal services required to serve a
neighborhood. The district's principal means of ingress and egress shall be
along collector roads, minor arterials, and/or major arterials as designated on
the County's Thoroughfare Classification Plan. (8/4/86) No B-1 Business
District shall be less than two (2) acres in area.

Section 55: B-2 Highway Business District
55-1: The purpose of this district shall be to provide for the proper grouping and
development of roadside business uses which will best accommodate the needs of the motoring public and businesses demanding high volume traffic. The district's principal means of ingress and egress shall be along collector roads, minor arterials, and/or major arterials as designated on the County's Thoroughfare Classification Plan. (8/4/86) No B-2 District shall be less than five (5) acres in area.

*Conditional Use Districts may be established for all the districts where special conditions or limitations are placed upon the uses permitted through the issuance of a special use permit and the zoning classification is voluntarily initiated by the landowner. A site plan approval is required.
