§ C. Lots and lot lines.

All lots shall front upon a public street. Lot lines shall be perpendicular or radial to street lines.

(1)

Minimum size. Lots served by a public sewerage system shall meet the minimum requirements of the zoning district in which they are located but in no case shall they be less than 7,200 square feet in lot area or have a lot frontage of less than 60 feet. Lots not served by a public sewerage system shall be not less than 75 feet wide at the building line nor less than 15,000 square feet in area. Greater area may be required for private sewage disposal if factors of drainage, soil condition or other conditions are considered to be potential health problems. The planning commission may require data from percolation tests to be submitted as a basis for passing on subdivisions dependent upon septic tanks as a means of sewage disposal.

(2)

Building setback lines. The minimum depth of building setback lines from the street shall not be less than 30 feet and, in the case of corner lots, 15 feet from the side street. However, if greater setbacks are required by the zoning ordinance of the city as now or hereafter adopted, these shall be provided.

(3)

Corner lots. Corner lots shall be sufficiently wider and larger in area to permit the building setback line outlined above.
