Retaining Walls

St. Leonard Volunteer Fire Department Retaining Wall Design

Calvert County Department of Public Works

Brudis & Associates, Inc. was responsible for providing preliminary and final engineering design services for civil/site improvements and for a second emergency exit roadway for the St. Leonard Volunteer Fire Department at Calvert Beach Road in Calvert County, Maryland.

To minimize embankment fill and for environmental mitigation purposes, a concrete retaining wall was required to facilitate roadway construction. The retaining wall measured more than 200 feet in length and 8 to 12 feet in height. BAI completed preliminary and final engineering design services for the project. Geotechnical investigations indicated that on-site soils would not support the retaining wall spread footing foundation. Aggregate piers and steel piles were evaluated and aggregate piers were used to support the retaining wall.
