This is what is referred to as the "Yuma Legislative District Notch". From North to South: The L.D. 13 notch boundary starts at Interstate 8 and Pacific Avenue and runs South to 24th Street. It then turns West to Avenue D, then turns South to County 14th Street, then turns East to Avenue A, then turns South.
The people who came up with these boundaries should have been fired. They totally abused their responsibility to the voter.
