§  4-100. Election districts; creation and alteration. 1. The State of   New York shall be divided into election districts  which  shall  be  the   basic  political  subdivision for purposes of registration and voting as   provided in this chapter.2. The creation, consolidation, division  or  alteration  of  election   districts shall be done by the board of elections.3.  a.  Each election district shall be in compact form and may not be   partly within and partly without a ward, town, city, a village which has   five thousand or more inhabitants and is wholly within one  town,  or  a   county  legislative,  assembly,  senatorial  or  congressional district.   Except as provided in paragraph b of this subdivision, election district   boundaries, other than those boundaries which are coterminous  with  the   boundaries  of those political subdivisions mentioned in this paragraph,   must  be  streets,   rivers,   railroad   lines   or   other   permanent   characteristics of the landscape which are clearly visible to any person   without  the need to use any technical or mechanical device. An election   district shall contain not more  than  nine  hundred  fifty  registrants   (excluding  registrants in inactive status) or, with the approval of the   county board of  elections,  not  more  than  two  thousand  registrants   (excluding  registrants  in  inactive status), but any election district   may be divided for the convenience of the voters.b. An election district in a city or town may divide a block, provided   that the board of elections prepares an alphabetical  list  of  all  the   streets  in  such  city or town with the election district for each such   street. If any such street is  divided  between  two  or  more  election   districts,  then  such  list  must contain the lowest and highest street   numbers in each such district and if the  odd  and  even  numbers  on  a   street  are  in  different  districts,  such  list must contain separate   listings for such odd and even numbers and if there  are  both  odd  and   even  numbers  in  such  different  election  districts,  such list must   contain separate listings for such numbers. Copies of such  lists  shall   be  filed  and  kept  open  to  public inspection in the offices of such   board. One copy of each such list shall be delivered, upon  request,  to   the  state  board  of  elections  and  to a person or officer designated   jointly by the speaker of the assembly and the  temporary  president  of   the senate. Surplus copies shall be sold at cost.4.  Any  election  district must be realigned when the total number of   registrants, excluding registrants in inactive status, at  the  time  of   the  preceding general election, exceeds the maximum number permitted by   this section by at least fifty registered voters.5. Any creation, consolidation, division  or  alteration  of  election   districts  in  any  calendar  year  shall  be made on or before February   fifteenth, and shall take  effect  on  April  first,  except  that  when   required by the creation or alteration of a political subdivision, other   than  an  election  district, in which candidates are to be voted for at   the next election, such creation, consolidation, division or  alteration   shall  be  made  and  shall  take  effect  immediately  upon creation or   alteration  of   such   political   subdivision.   No   such   creation,   consolidation,  division  or  alteration  shall be made between February   twentieth of a calendar year ending in seven and  December  first  of  a   calendar  year  ending  in  zero  unless  required  by  the  creation or   alteration of a political subdivision.
