Drainage and Stormwater Management Design, Statewide
Maryland State Highway Administration
RJM Engineering has a long history of providing water resources engineering services as a sub-consultant on many Maryland State Highway Administration projects. Types of projects have included new roadways, roadway widenings, safety improvements, intersection improvements, bridge replacements, culvert replacements, ADA/sidewalk/trail improvements, and noise walls. RJM’s design efforts have been in all project phases from planning to P.I., Semi-Final, Final, PS&E and construction phase services.
Services typically provided by RJM have included hydrologic studies, stormwater analysis and concepts, and flood plain studies. Designs have been provided for drainage, stormwater management and erosion/sediment control. RJM’ engineering staff is fully experienced with the latest MDE regulations and SHA directives, and remains current with Maryland erosion/sediment control certifications.
More recently, RJM has provided design services for water quality mitigation for TMDL (Total Daily Maximum Load) at numerous sites throughout Maryland. Many of these projects have been completed in three phases: Exploratory, Concept and Final Design. Exploratory efforts have included assembling existing data, determining potential ESD/BMP locations, field investigations, verifying existing drainage patterns and identifying potential environmental impacts and utility conflicts. Concept efforts have included developing concept stormwater management reports and coordination with SHA and MDE. Design efforts have included all semi-final and final design plans, specifications, cost estimates, reports, addressing SHA and MDE comments, and complete PS&E submittals.
