MAR: Political Redistricting


Political Redistricting

The redistricting process in Washington, DC is well under way.   Redistricting in DC involves creating new political boundaries based on the United States Census Bureau’s 2010 Census.  The new political boundaries for Wards,  Advisory Neighborhood Commission (ANC) and Single Member Districts (SMD) take effect on January 1, 2012.  Currently, only the Ward boundaries for 2012 have been approved by the DC Council and the Ward 2012 values for addresses lcan be found in the WARD_2012 field in the he Master Address Repository (MAR).

As of August 16, 2011 there are 2,815 primary addresses whose Ward values will change next year. An example of an address whose WARD_2002 is different from its WARD_2012 value is 501 NEW YORK AVENUE NW;  its Ward 2002 value is 2, and its Ward 2012 value is 6.

Additionally, there are many applications and databases within DC Government that use one or more of these political boundaries.  Some of these applications will need to be modified to reflect these new political boundaries.   In order to support this effort, the MAR Team will both update new political boundaries while maintaining the current political boundaries.  

A new field called WARD_2012 has been created in the Address View and the AddressPt feature class on DCGIS Central.  The enhanced MAR Web Services and modifications to the MAR Sample Client will be made available in September 2012.

The WARD, ANC, and SMD fields will always have the effective political jurisdictional values.  When the new boundaries take effect on January 1, 2012,  the WARD, ANC, and SMD fields will reflect the new political jurisdictions that have taken effect.  The the previous WARD, ANC, and SMD values from 2002 will still be in effect till December 31, 2011 and will still be available in the WARD_2002, ANC_ 2002, and SMD_2002 fields.

The Address View and AddressPt Feature class have been modified to include the following fields:
  • New field names
    • WARD_2002, text, 25
    • WARD_2012, text, 25
    • ANC_2002, text, 25
    • ANC_2012, text, 25 (currently NULL because boundaries have not been finalized)
    • SMD_2002, text, 10
    • SMD_2012, text, 10 (currently NULL because boundaries have not been finalized)
  • Keep Existing Field Names
    • WARD
    • SMD
    • ANC

What are the benefits of the MAR?

The MAR allows the District Government to more easily compare information across databases and agencies. The format and quality of address information varies across government systems, making it nearly impossible for government to identify all the activity associated with a given address. Now, addressing standards are built into the MAR. These standards define the valid components of DC addresses (Address ID, Number, Street Name, Street Type, and Quadrant), including their correct formatting and spelling.

Nearly, 80% of databases in local government contain some spatial data. Similarly, a large percentage of DC Government databases contain spatial data. The most common is an address.Addresses are used in all sorts of city databases including crime incidents, student, building permits, health inspections, voter rolls, business licenses.

An address database with reliable information is critical in easily locating addresses. It is even more important for addresses which are located in illogical places.

  • The adress records now have two additional fields RES_TYPE and ACTIVE_RES_OCCUPANCY_COUNT. The RES_TYPE field indicates the residential status of an address. The domain of values is 'RESIDENTIAL' 'MIXED USE' and 'NON RESIDENTIAL' The ACTIVE_RES_OCCUPANCY_COUNT field shows the number of residential occupancies (housing units) at a particular address. An address of a large apartment building might have a value of 98 and a detached single family home would have a value of 1.  For more info please see MAR Blog Post.

  • The MAR Data Team is working on redistricting efforts. Due to the 2010 Census political boundaries including Ward, ANC and SMD, will need to change. The MAR will be used to estimate sub Census Block populations.

  • Dozens of alleys were visited to search for rear address. A few new rear addresses were found including 327 REAR L STREET NE. Please see the blog post.
