About This Guide

Quadrant & Circle is an independent field guide to Washington, D.C. It exists to explain the mechanisms of the city — how the address system works, why the buildings stop at the height they stop at, how the transit map is drawn, what the local political arrangement actually is — in plain editorial prose, with the sources named.

The organizing idea is simple. Washington is described constantly and explained rarely. A visitor can read a great deal about the city and still not be able to find an address, and a new resident can live here for a year without ever being told why the same street name turns up in four different places. These guides are written to close that gap.

What it covers

The guide covers the resident city and its physical fabric: the street grid and the survey that produced it, the neighborhoods, the U Street corridor, the building height rule, the Metro, the parks and rivers, the local music and food, and the District's political status. The full index lists every page with a description.

What it does not cover

It is not a listings guide. There are no recommendations, no ratings, no opening hours, no reservations advice and no shopping. Information of that kind goes out of date within months and is better sought from the businesses themselves.

It is also not a guide to the federal government. The workings of Congress, the agencies and the political news cycle are covered exhaustively elsewhere; nothing useful would be added by covering them again here. Federal institutions appear only where they explain something about the city — the National Park Service because it administers a great deal of the ground, the Congress because it reviews District legislation.

How it is written

The pages are unsigned editorial written in the third person. They are deliberately plain: a mechanism is explained, and then the guide says what that mechanism means at street level. Where a popular story about the city is disputed or simply wrong — the belief that the height limit is set by the Capitol, the folklore around the missing J Street — the guide says so and presents the competing explanations rather than picking the more entertaining one.

Facts are kept to the standard public record. Statements about agencies, statutes, dates and places are drawn from primary public sources, principally the National Park Service, the National Capital Planning Commission, the District's open data catalog and the published District Code. Nothing is attributed to a named individual, and no interviews are represented.

Corrections and sources

Where a guide relies on a public record, it links to that record directly in the body text rather than gathering citations at the foot of the page, so that a reader can check a claim at the point it is made. Preference is given to the agency that holds the authoritative version of a fact: a park boundary to the Park Service, a statute to the published code, a population figure to the census.

Facts here change slowly — a survey line from 1791, a statute from 1910 — but they do change, and where the guide states something that a linked source contradicts, the source is right and the page is wrong.
