Mill Creek

This image from the late 1880s shows construction of the culvert at 47th Street and Haverford Avenue. The culvert was filled with tons of dirt to form a deeply buried sewer, and roads and houses were built above it, with disastrous effects in later decades.

Urban gardening today in Mill Creek's "buried floodplain" at 4837-59 Aspen Street, formerly a residential site. Established in 1975, with support from the Pennsylvania Horticultural Society.
