Implement depressed medians (a ditch/swale between divided roadways) to hold stormwater and raised medians (a curbed section that typically occupies the center of the roadway) to convey stormwater away from roadway.
Moderate/High – improved stormwater collection and flood control reduces damage to roadways
Moderate – it is generally cost-prohibitive to modify engineered infrastructure once constructed; however, smaller scale projects may have greater flexibility and lower retrofit costs
Cost; potential downstream impacts
Ensure that drainage conveyance does not cause flooding to equity areas.
