Unless otherwise provided by these regulations, in a business or industrial zone, every building shall be required to be set back from the property line such a distance as may be necessary to keep its street wall, walls or covered porches thirty-five (35) feet from the center line of the street or streets upon which its lot may abut or front, except that where twenty-five percent (25%) of the length of a given block front is occupied by buildings on the street line or within one (1) foot of same, no setback shall be required for additional buildings on said block front.

Wherever the Common Council shall have established a building line or wherever the Common Council may in the future establish a building line, as provided in the Charter of the City of Norwalk, then such building line shall control the distance that the buildings shall be set back upon the lot, in lieu of these regulations.

No building or structure shall be maintained within seventy (70) feet of the center line of Connecticut Avenue as established by George C. Stout, City Engineer, and which center line is shown and delineated on a certain map entitled "Map Showing Center Line of Traveled Portion of Connecticut Avenue, Norwalk, Connecticut, August, 1944," said map on file in the Town Clerk's office.

No building or structure of any kind shall be erected or maintained within fifty (50) feet of the center line of Main Avenue as shown on a certain map entitled, "Map of Main Avenue, Showing Center Line Established for Zone and Building Line Purposes from Merritt Parkway to Wilton Town Line, 1946," on file in the Town Clerk's office.

All properties used for commercial and industrial purposes shall provide a buffer strip on every side which abuts a residence zone, except that no buffer or graduated setbacks from residence zones shall be required where the abutting property is within a limited access highway or railroad right-of-way. An existing commercial or industrial building or use shall be exempt from the requirements of this section. All buffer strips must be kept free of litter and maintained to the satisfaction of the Zoning Inspector.

Each buffer strip shall be a minimum of 10% of the average lot width or depth, but need not exceed 30 feet maximum.

The treatment of the buffer strip shall be subject to the approval of the Zoning Inspector. Fences, walls, berms, existing vegetation or natural changes in grade may supplement planted material or be considered in lieu thereof when, in the opinion of the Zoning Inspector, the intent of this regulation is adequately served. The Zoning Inspector shall consider the extent to which the treatment of the buffer strip screens noise, glare, smoke and visibility from adjacent properties.

So as to reduce traffic generation and traffic hazards, after the effective date of this amendment to this section and these regulations, no retail gasoline station shall be constructed or located within 2,000 feet of an existing gasoline filling station (retail). This provision shall not, however, make nonconforming uses of retail gasoline filling stations otherwise conforming as of the effective date thereof.
