Description: <DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>Data Type: December 31, 2018 archive. Note broad changes to county precinct boundaries generally occur every two years; however, slight modifications to the representation of such may occur due to general ASP editing of the BaseLine feature class. Such occurred on a daily to weekly basis in 2018.</SPAN></P><P><SPAN>The county precinct number is a ten-digit code conforming to a specified format:</SPAN></P><P><SPAN>DIGIT 1: FEDERAL HOUSE (CONGRESSIONAL) DISTRICT</SPAN></P><P><SPAN>DIGITS 2-3: STATE SENATE DISTRICT </SPAN></P><P><SPAN>DIGITS 4-5: STATE HOUSE DISTRICT</SPAN></P><P><SPAN>DIGITS 6-7: COUNTY CODE ("30")</SPAN></P><P><SPAN>DIGITS 8-10: UNIQUE PRECINCT IDENTIFIER (PER COLUMNS 1-7)</SPAN></P><P><SPAN>As an example, precinct 7222030005 is the 5th unique precinct serving the combination of Jefferson County (30) and the 7th Congressional district, 22nd State Senate district, and 20th State House district.</SPAN></P><P><SPAN>County precinct data, along with all core jurisdictional data pertinent to elections, is maintained in the AddressStreetPolitical (ASP) production database by IT Services via the ASP Tools. </SPAN></P><P><SPAN>Source data is the BasePoly feature class, a subset of all BaseLine geometry which closes upon itself to form polygonal data to which jurisdictional attributes are attached. BasePoly is an atomic-level polygonal feature class coincident with BaseLine features due to topology rules in place in the ASP database. By atomic, we mean each polygon feature carries the core political data (county precinct {with federal house, state house and state senate districts embedded within}, city code {municipal status}, city ward, city precinct, commissioner district, regional transportation district {RTD}, traffic impact fee area {TIFA}, south jeffco local improvement district) used by the Elections Office in the determination of ballot styles. </SPAN></P><P><SPAN>Whenever editing to BaseLine geometry occurs or whenever BasePoly attribution is edited, BasePoly is dissolved for each core political component (column) by the ASP DERIVATIVE processing. In this case, CountyPrecinct results from a dissolve of basePoly's COUNTYPRECINCT column. All derivatives, like CountyPrecinct, are then re-freshed in SDEWHP by the ASP To Warehouse (ASP2WH) processing.</SPAN></P><P><SPAN>County precinct is a core component of the data utilized by IT Services, via the SCORE Split and SCORE Comparative processes, to help the Elections Office maintain County data in the State of Colorado Registration and Elections (SCORE) system.</SPAN></P><P><SPAN>Data is in State Plane Grid Coordinates, Colorado Central Zone, NAD83 (US feet). </SPAN></P></DIV></DIV></DIV>
