[Ord. No. 646 §2]
Where uncertainty exists with respect to the boundaries of the various districts as shown on the zoning district map made a part of this chapter, the following rules shall apply:
(a) 
The district boundaries are the right-of-way center lines of either streets or alleys unless otherwise shown; and where the district designated on the map is bounded approximately by street or alley lines, the street or alley right-of-way center line shall be construed to be the boundary of such district.
(b) 
In the event that a zoning district boundary line is shown on a zoning district map as following a property line or a political boundary line, the actual location of such zoning district boundary line shall govern, as determined by survey, rather than the representation of the location of such boundary line on the district map, if there is a discrepancy between the two locations.
(c) 
Where the district boundaries are not otherwise indicated and where the property has been or may hereafter be divided into blocks and lots, the district boundaries shall be construed to be the lot lines; and where the districts designated on the zoning district map are bounded approximately by lot lines, the lot lines shall be construed to be the boundary of such district unless the boundaries are otherwise indicated on the map.
(d) 
In unsubdivided property, the district boundary lines on the zoning district map shall be determined by use of the scale appearing on the map.
(e) 
In interpreting and applying the provisions of this chapter, they shall be held to be the minimum requirements for the promotion of the public safety, health, convenience, comfort, prosperity or general welfare. It is not intended by this chapter to interfere with or abrogate or annul any easements, covenants or other agreements between parties; provided, that where this chapter imposes a greater restriction upon the use of buildings or premises or upon height of buildings, or requires larger open spaces than are imposed or required by other ordinances, rules, regulations or by easements, covenants or agreements, the provisions of this chapter shall govern.
