This ordinance, BL2025-897, amends Sections 15.64.010, 15.64.130, and 15.64.131 of the Metropolitan Code of Laws to update residential infill regulations. Key changes include redefining "Infill (regulated residential)" to encompass associated property improvements in impervious area calculations. It also removes the definitions for "Residential property" and "Non-residential property" from the code. The ordinance modifies exemptions for individual residential dwellings from drainage plan review and mandates that development plans for regulated residential infill projects adding at least 800 square feet of impervious area be prepared and stamped by a licensed land surveyor or professional engineer. Furthermore, it requires the Metropolitan Department of Water and Sewerage Services (MWS) to update the Stormwater Management Manual Standards to include provisions for artificial turf installations, multi-family structures (three-family or more), new tree credits for residential infill, and revised development plan submission requirements.
