Hydrology Urgent Needs

Brudis & Associates, Inc. (BAI) was responsible for numerous urgent needs services including inventories/inspections of outfalls, analysis of failing drainage systems and slopes, and recommendations/designs for proposed solutions. BAI reviewed available existing information, performed field inspections and surveys (topography, sizes, cross sections, and invert elevations of conveyance systems), and wetland delineations and forest stand delineations. Hydrologic and hydraulic (H&H) analyses were performed for computing the design discharges for sizing the piping/channel system, and included TR-55, Rational Methods, HY-8, or spreadsheet analysis, as appropriate. BAI designed feasible and cost-effective engineering solutions for the resolution of the failing drainage systems and slopes, and prepared construction documents for the design of the outfall pipe/channel, plans, profile, cross sections, limit of disturbance, erosion and sediment control plans, and cost estimates. In addition, BAI also provided construction phase services.

Projects Included:

  • 713 W Montgomery Ave Drainage Issue.
    Project involved rerouting and replacing of an existing 12” pipe located at a private property at 713 W Montgomery Ave in the City of Rockville Maryland.
  • MD 175 Ramp to US 29 Drainage Issue.
    BAI provided a new storm drain design and layout of a failed 12” storm drain pipe located on MD 175 eastbound ramp to US 29 southbound, in Columbia, MD.
  • I-83 Near Structure #03400X0 Drainage Issue.
    BAI designed and developed the construction cost estimate for stabilizing an existing roadside ditch and replacing an undermined and broken concrete channel along I-83 NB in Baltimore County, MD.
  • I-495 Slope Failure near CSX Rail Road and Drainage Issue.
    BAI provided analysis to investigate the cause(s) of drainage issues related to the runoff at the intersection of CSX railway overpass and I-495.
  • MD 710 W after MD 10 Bridge.
    Project involved preparation of storm drain design at MD-710 W (Ordnance Road) intersection with MD-10 (Arundel Expressway) in Anne Arundel County, Maryland.
  • MD 3 South of MD 32 Drainage Issue.
    Project involved design to unclog an existing 48” reinforced concrete pipe and the unintended impoundment of runoff due to the clogged pipe between MD 3 northbound and southbound located in Anne Arundel County, MD.
  • MD 135 and Vine Street Drainage Issue.
    Project involved preparation of two alternative solutions for directing stormwater runoff away from a newly constructed retaining wall along Vine Street near MD 135 in Westernport, Allegany County, Maryland.
  • US 40 Ramp to I-70 and WB I-70 Drainage Remediation.
    Project involved site investigation, design of new riprap ditches and preparation of plans and cost estimates for two outfalls along US 40 ramp in Frederick County, MD.
