Isherwood Street NE is in a compact neighborhood south of Benning Road NE called Rosedale. That area “fills in the so-called ‘Isherwood notch,’ where the L’Enfant Plan ends east of 15th Street NE and north of C Street NE,” said Michael Harrison, who is compiling a record of street name derivation. None of this has anything to do with Isherwood Street, but it’s a reminder that “new” maps that purport to show “old” things can’t always be trusted. “Isherwood Street itself was created through further subdivisions of Rosedale and Isherwood Squares 7 and 8, now Squares 4544 and 4545.”ADIsherwood Street NE was named in 1884. The city’s northern border — Boundary Road, later Florida Avenue NE — dips south around present-day 15th Street NE before heading east again at present-day C Street NE.
