Late yesterday morning, a three-alarm fire in North Beach tore through four units on the 600 block of Green Street (also known as Beach Blanket Babylon Boulevard), next door to the famed Beach Blanket Babylon theater. (The theater was unscathed, with show performances, for better for for worse, being unaffected by the blaze.) Although the fire was controlled less than an hour after firefighters arrived, it managed to displace six residents and cause around $1.35 million worth of damage. No injuries were reported.
