The boundaries for each district listed in this chapter are identified on the map entitled "Official Zoning Map of the Town of Riga," dated with the effective date of this chapter, together with all subsequent amendments thereto, which shall hereinafter be known as the "Zoning Map."
There shall exist only one Official Zoning Map, which shall be kept in the office of the Town Clerk and shall bear the Seal of the Town of Riga, a certification by the Town Clerk that it is the "Official Zoning Map of the Town of Riga" and its date of adoption. Said Zoning Map shall be on material suitable for reproduction. Any copies of this map which may from time to time be published and distributed shall be used for reference purposes only. Changes made in district boundaries or other matters portrayed on the Zoning Map under the provisions of this chapter shall be permanently affixed to the Zoning Map promptly after the amendment has been approved by the Town Board and shall convey information as to the date and nature of the change. Should the Zoning Map become damaged, destroyed, lost or difficult to interpret because of the changes and additions, the Town Board may, by resolution, authorize a new Official Zoning Map to be prepared, incorporating any amendments or changes adopted subsequent to the preparation of the former map. Such new map shall bear a date of preparation and a listing of all changes and amendments incorporated thereon.
A. 
Where uncertainty exists, the following rules shall apply in determining the location of zoning district boundaries as shown on the Zoning Map:
(1) 
Where district boundaries are indicated as approximately following the center line or right-of-way line of streets, highways, railroads or streams, those lines shall be construed to be the district boundaries.
(2) 
Where district boundaries are indicated as approximately following lot lines, those lines shall be construed to be district boundaries. If a district boundary divides a lot into two or more districts, the entire lot shall be placed in the more restrictive zoning district by the adjustment of the district boundary, provided that the boundary adjustment is for a distance of less than 20 feet. If an adjustment of more than 20 feet is required, the property line may be deemed to be the district boundary.
(3) 
Where district boundaries are not indicated as approximately following the lines identified in Subsection A(1) and (2) above and any such line is not described by a actual dimension, the location of boundary lines shall be determined by the use of the scale designated on the Official Zoning Map.
(4) 
Whenever any street or other public way is vacated in a manner authorized by law, the zoning district adjoining each side of such street or public way shall be automatically extended to the center of the former right-of-way and all of the area included in the abandoned area shall then be subject to all regulations of the extended districts.
B. 
In the event that none of the above rules is applicable or there is still uncertainty, the location of such boundary, unless the same is indicated by dimensions on the map, shall be determined by the Zoning Board of Appeals.
Whenever access to a development can be had only across land in another municipality, the Planning Board may request assurances from the Attorney for the Town of Riga that access is legally established and from the Engineer for the Town of Riga that the access road is adequately improved or that a performance bond or other satisfactory security has been duly executed and is sufficient in amount to assure the construction of the access road. In general, lot lines should be laid out so as not to cross Town boundary lines.
