Hoblitzelle Park Erosion Control
The City of Plano Parks And Recreation Department maintains over 70 miles of hike and bike trail within its jurisdiction, many of which are built along the city’s creeks. Walter P Moore was contracted by the Parks and Recreation Department to protect one such trail along Rowlett Creek. The stream was experiencing erosion along the outer bend of the creek, threatening to undermine the trail and expose it to bearing failure.
Walter P Moore provided civil engineering and project management services for the construction of a 400-foot long, 22.5-foot tall modular block retaining wall along the Hoblitzelle Park Trail. Walter P Moore engineers designed a rock anchored retaining wall that stabilizes the outer bend of Rowlett Creek on the north side of the channel and added gabion mattress to protect the toe of the wall and bottom of the channel against future undermining. The wall’s curved alignment was designed to preserve the natural curves of the creek and was recessed into the natural bank to preserve maximum channel flow capacity. At the end of construction, the trail was re-built and safety railing was added per AASHTO Standard Guidelines.
