From the Fan community news site:
Redistricting of the State Senate and House of Delegates districts based on the 2010 Census numbers was made official recently, with some impact on the neighborhood.
A piece of the Fan close to Monroe Park, all of Oregon Hill and Byrd Park, and much of the Forest Hill area that have been part of State Senate District 9, currently held by Donald McEachin (D), will now be in State Senate District 10, held by John Watkins (R). Interestingly, with these and other changes, both of these Senate districts are now less partisan than before the redistricting: District 9 has been redistricted to be 6.3% more Republican (up to a whopping 36.5%), while District 10 is now 7.5% more Democratic (40.7%).
Most of Oregon Hill (everything below the Expressway) was also moved from Delegate Jenn McClellan’s 71st District to Delegate Betsy Carr’s 69th District. Betsy Carr previously represented Oregon Hill when she was the 5th District School Board Representative.
