The Highway Hydraulics Division (HHD) established the Stormwater and Drainage Asset Management Program to guide the operation and remediation of permanent stormwater and drainage assets owned by the Maryland Department of Transportation State Highway Administration (MDOT SHA) that convey and treat highway runoff. The program provides preventive care and remedial solutions. It applies a life-cycle approach to its management of stormwater and drainage assets. Operations of these assets, especially routine maintenance, is critical in this life cycle. Routine maintenance ensures that these assets function effectively and prevents costly repairs and retrofits.
HHD developed Stormwater Management (SWM) Facility Routine Maintenance Manuals (linked below) to inform MDOT SHA maintenance personnel concerning routine maintenance of SWM facilities. These facilities are structural and non-structural practices that manage the volume, flow rate, and quality of stormwater runoff before that water enters natural waterways or groundwater. These SWM facilities play an important role in protecting Maryland’s water and land resources.
In addition, a presentation was done on July 11, 2019 to review many of these procedures with ADE-M’s of the organization. The presentation materials are available here as follows:
