Project Description

Black Hill Regional Park is located at 20930 Lake Ridge Drive in Boyds, Maryland. The purpose of the causeway culvert renovation project is to replace the existing culvert pipe infrastructure on Black Hill Road. The culverts have deteriorated and need to be replaced. The existing culvert pipes will be abandoned and sealed with concrete. In order to complete this, the lake level will be lowered in December through the end of February. Black Hill Road will be closed during this time. The lake is expected to return to its normal level by mid-March. For ease of maintenance the new culvert pipes will be more centrally located within the causeway. The road will be repaved at the completion of the project


There are currently four 60″ corrugated metal culvert pipes running beneath the Black Hill Road causeway. This is located on Little Seneca Lake at the upper portion of the Cabin Branch Stream Tributary. When the lake was constructed in 1985, the service road crossing at this location was raised to be above the lakes normal water level. The area above the causeway was transformed into a forebay to the lake for the Cabin Branch Tributary. The ends of the culvert pipes are submerged, and severe corrosion is occurring at all four culverts. There are warning signs at each end of each culvert cautioning, “Do Not Stand On Pipe.” The signs were installed to caution anglers against standing and fishing from on top of the deteriorating culverts. The existing road pavement over the culverts is showing areas cracking, and a section of the pavement was previously patched.

Status/Project Update

Starting at the beginning of December 2018, the Lake water level will be lowered so that the existing pipes can be accessed. The adjacent boat ramp will no longer be accessible as Black Hill Road will be closed until the mid-March 2019.
