Looking west from N. Markoe St., the western boundary of Lucien E. Blackwell Homes. Shown here in their proximity to Parkway West High School (formerly Sulzberger Middle/Junior High School) are Lucien E. Blackwell Park and Lucien E. Black Community Center. The park is bounded east to west by N. Markoe and N. 47th Street. It lies on the buried floodplain of the Mill Creek sewer. Running along the base of the high school embankment, N. 47th Street charts the path of the buried sewer.
