Drainage, Stormwater Management, Erosion & Sediment Control

I-68 Drainage Improvements

Maryland State Highway Administration

To control extensive erosion and drainage problems along Interstate 68, Brudis & Associates, Inc. provided detailed drainage analysis, complete with hydraulic computations to repair this embankment.  Upon completion of the analysis, BAI developed complete construction plans, specification and cost estimates for the stream outfalls and drainage in West Midlothian, Maryland. 

For its engineering design, BAI was awarded the Maryland Quality Initiative (MDQI) Award of Excellence for Erosion and Sediment Control on this project. 

Building 245 Drainage Study

National Institute of Standards & Technology

Under an indefinite delivery contract, Brudis & Associates, Inc. is responsible for providing engineering services for the US Department of Commerce, National Institute of Standards and Technology (NIST). The NIST is a Research and Development (R&D) facility with 52 buildings and supporting structures located in Gaithersburg, Maryland. 

The Radiation Physics Building located on campus has an existing drainage system (a closed storm drain system and shallow swales) that does not adequately manage rainfall.  This results in flooding.

BAI provided a detailed drainage study of the area to eliminate the flooding impacts.  BAI also developed concept plans which addressed grading and drainage alongside the building.

Bellona Avenue Drainage Improvements

Baltimore County Department of Public Works

Under a multi-year agreement with the Baltimore County Department of Public Works, Bureau of Engineering & Construction, BAI was responsible for the drainage improvements of a  ½-mile segment of suburban roadway. 

The project has involved the development of conceptual design and preliminary design documents for roadway and roadside drainage improvements.  Considerable forest stand impact analysis, downstream hydrologic and hydraulic analyses were also necessary due to the maturity of this neighborhood.  A curb and gutter/closed pipe system was developed, and an analysis was performed to demonstrate that the 100-year storm event for the Bellona Avenue drainage and the nearby Roland Run Stream did not occur at the same time, so as not to breach a levee that was present around a neighborhood near the downstream outfall.

Maryland Route 30 Drainage

Maryland State Highway Administration

As a specialized member of the Maryland State Highway Administration (SHA) Project Team, Brudis & Associates, Inc. successfully provided complete hydraulic, hydrology engineering services and drainage design for the MD Route 30 Streetscape project located in Manchester, Maryland.

BAI’s design involved modifications to the existing drainage system in order to accommodate roadway and sidewalk improvements, replacement of the existing inlets and connections, provisions for supplemental sump inlets and pedestrian crossings. The project also included structural design services for the existing stone arch culvert and junction boxes beneath roadway.
