  10. RDP input to BAS • Still in planning stages • 2015 to 2016 (Informal Review) • Redistricting liaisons can report BAS changes to Census BAS team and they will contact local BAS officials and perform necessary research. NOTE: BAS and Tribal BAS are centralized from Census Headquarters • 2017 to 2018 (Possible formal phase) • Redistricting liaisons can report BAS changes to Census BAS team and they will contact local BAS officials and perform necessary research. • 2019 • Redistricting liaisons must contact local BAS official and ask them to report changes to Census BAS team. • 2020 • In addition to the standard BAS materials, Boundary Validation Program materials will be available for review. Redistricting liaisons must contact the local BAS official or the jurisdiction’s highest elected official and ask them to report changes to Census BAS team. NOTE: Changes must have been effective as of January 1st 2020

  11. RDP input to BAS • Requires coordination at all levels of government. • Reporting changes will likely require group consultation between the BAS Team, RDP Liaison, and local BAS Official. • BAS Team will “close the loop” on reported changes • Attention early in the decade creates a virtuous cycle in which work later becomes easier. • Authority for change must follow BAS rules and state and local legal framework

  12. RDP input to BAS • Opportunity to review BAS updates occurs multiple times a year. • Through partnership shapefiles on the BAS website each December • Through the new TIGER/Web application • http://tigerweb.geo.census.gov • Quality Measure Pilot – As described in the 2013 Federal Register Notice for BAS, the BAS Team is conducting a pilot on the use of cadastral data in the assessment, improvement, and maintenance of legal boundaries. • https://federalregister.gov/a/2012-20579
