DRAFT REDISTRICTING PLANS REVIEWED BY THE BOARD
November 16, 2021
Based on the Board discussion and direction at the November 2, 2021 (Item No. 4) meeting, the following maps will consideration by the Board of Supervisors on November 16, 2021:
- Draft Yellow Plan
- Draft Purple Plan
- Draft EE 2.0 Plan
Draft Map: Yellow Plan
The Draft Yellow Plan originated from the Unity Mapping Table, who assembled a coalition of organizations and submitted a letter (COI No. 51) and presented to the 2021 Advisory Redistricting Commission on October 20, 2021 (COI No. 108). The Coalition provided information and met with Redistricting Partners to have their proposal developed in Maptitude for continued analysis and adjustments. The Commission recommended this map to the Board on November 2, 20201 based on the minority-representation organizations that contributed to the map’s development. Here is a link to an enlargeable version of the map: Enlargeable Draft Yellow Plan
Draft Map: Purple Plan
The Draft Purple Plan originated from maps developed by Commissioners after the first few meetings with communities of interest testimony. Additional versions were submitted and refined after subsequent presentations. Members of the community also began to create adaptations based on the original submissions. Here is a link to an enlargeable version of the map: Enlargeable Draft Purple Plan
Draft Map: EE 2.0 Plan
The Draft Purple Plan originated from maps developed by Commissioners after the first few meetings with communities of interest testimony. Additional versions were submitted and refined after subsequent presentations. Members of the community also began to create adaptations based on the original submissions. Here is a link to an enlargeable version of the map: Enlargeable Draft Purple Plan
DRAFT REDISTRICTING PLANS REVIEWED BY THE BOARD
November 16, 2021
Based on Board direction and discussion, Administration worked with Redistricting Partners to reduce deviations and to amend district boundaries of the three maps above to meet state and federal requirements. To implement the Board's direction, boundaries were adjusted as recommended during public communities of interest testimony, to reflect San José neighborhood boundaries, and to follow natural boundaries such as major roadways.
Draft Yellow Plan: First Refinement
Refinements to the Draft Yellow Plan include reducing the proposed size of District 5. This was achieved by moving the boundary between Districts 1 and 5 north, but Los Gatos and Almaden Valley remained with District 5. Many changes were made to communities of interest to unify them with the districts with similar demographic factors, as conveyed during communities of interest testimony to the 2021 Advisory Redistricting Commission and during the November 2, 2021 special joint meeting of the Commission and the Board.
Draft Purple Plan: First Refinement
The Draft Purple Plan has a low total plan deviation, followed natural boundaries, and incorporated communities of interest testimony, limiting adjustments that could be made without splitting cities or communities of interest.
Draft EE 2.0 Plan: First Refinement
Refinements to the EE 2.0 map smoothed out the southern boundaries of the proposed Districts 2 and 4 to follow major roadways and extends the proposed boundary for Districts 3 and 4 to the west of the Norman Y. Mineta San José International Airport.
