Creekview Retaining Wall and Roadway Improvements
Walter P Moore provided civil engineering services to repair a section of roadway that had experienced settlement of approximately 1 foot since its construction in 2001. The roadway was originally constructed near the outside bend of a creek where partial height retaining walls were constructed at the top of the creek bank. The retaining walls were at risk of failure from the creek erosion.
Walter P Moore first prepared a study of the area to recommend potential solutions to both the roadway settlement and the creek erosion. The resulting design included protection of the existing retaining walls with another erosion protection retaining wall. The new wall is stabilized with rock anchors. The street and 5 feet of the fill beneath were removed and replaced so that the road is founded on adequately compacted material. A 12-inch water main was also replaced, as well as a storm sewer in the street which had experienced significant movement related issues.
