Monroe Off-street Parking and Loading Drainage Requirements.

Any new surface parking lot with twenty-five (25) or more parking spaces or additions to existing parking lots of twenty-five (25) or more vehicle parking spaces must be designed to filter or store the first inch of rainwater during each rain event. This can be accomplished through the use of pervious paving, rain gardens, bio swales, detention areas, constructed wetlands, and other methods deemed appropriate by the city engineer. Where installed, detention areas should be appropriately designed and located to filter, store and convey the expected storm water flows from surrounding paved areas.
