We characterize those domains in the plane whose boundary is a chord arc curve in terms of some L2 integrals, which are mainly a version of Green's theorem. As a consequence of this we obtain a "converse" to a theorem due to Laurentiev that states that for such domains harmonic measure and arc length are A∞ equivalent.
