District Boundaries

The boundaries of the districts designated and established herein are as shown on that certain map entitled "ZONING MAP OF THE CITY OF TUSTIN" incorporated herein and made a part of this Chapter by reference as if herein fully set forth and to which reference is hereby made for full particulars as to the location of the areas shown within said districts.

d
Uncertain Boundaries

Where the exact boundaries of a district cannot be readily or exactly ascertained by reference to the Zoning Map of the City of Tustin, the boundary shall be deemed to be along the nearest street or lot line, as the case may be. If a district boundary line divides or splits a lot, the lot shall be deemed to be included within the district which is the more restrictive. The provisions of this Section shall not apply to acreage. (Ord. No. 157, Sec. 3.3)

e
Prezoning of Unincorporated Territory

Said Zoning Map of the City of Tustin may also contain, from time to time, zones designated for areas not lying within the corporate boundaries of the City of Tustin. The designations of zones fixed by prezoning pursuant to this Section of any unincorporated territory adjoining the City shall become the effective designated zone of said property at the same time that the annexation of such territory becomes effective. Any territory hereafter included within the City of Tustin, which, at the time its annexation becomes effective does not have a zone designated by prezoning, shall be designated by the zone which the territory bore under the County Zoning Ordinance, provided this Chapter has a district bearing the same designation. Any such land which did not bear a designation under the County Zoning Ordinance which is contained in this Chapter shall be designated as being in the "U", or Unclassified district. (Ord. No. 303, Sec. 1)

Except as provided in Parts 2, 3 and 4, no structure shall be erected, reconstructed, enlarged, altered or moved; nor shall any building or land be used except as hereinafter specifically provided and allowed in the districts in which such structure and land are located. (Ord. No. 157, Sec. 4)
