5. Remedies. (a) Upon a finding of a violation of any provision of this section, the court shall implement appropriate remedies to ensure that voters of race, color, and language-minority groups have equitable access to fully participate in the electoral process, which may include, but shall not be limited to:
6. Procedures for implementing new or revised districting or redistricting plans. The governing body of a political subdivision with the authority under this title and all applicable state and local laws to enact and implement a new method of election that would replace the political subdivision's at-large method of election with a district-based or alternative method of election, or enact and implement a new districting or redistricting plan, shall undertake each of the steps enumerated in this subdivision, if proposed subsequent to receipt of a NYVRA notification letter, as defined in subdivision seven of this section, or the filing of a claim pursuant to this title or the federal voting rights act.

The prospective plaintiff shall also send by first class mail or email a copy of the NYVRA notification letter to the civil rights bureau.
