You may. In Maryland, any project that disturbs 5,000 square feet or more of ground, or 100 cubic yards of earth, needs an approved erosion and sediment control plan first. That is the state's line and not the whole answer: near the water the county's Critical Area rules apply as well, so say how close the water is when you ask for a price. ### Which creeks run by Arden on the Severn? Four, on the county's stream maps, which name Plum Creek, Gumbottom Branch, Cypress Branch and Indian Creek Branch in or along Arden on the Severn. Which way your own lot leans shows after a rain, so say where the water runs when you describe the wet spot. ### Has any stormwater work been done in Herald Harbor? Yes. County restoration records for Herald Harbor include three finished stormwater projects: a stormwater management retrofit at Valentine Creek, completed in 2017, and step pool storm conveyances at Buttonwood Trail, completed in 2016, and at Bonaparte Road, completed in 2017. Those are projects in the county's records, none of them ours. Rain that sits on your own lot is where a rock channel comes in. ### Where does the water in a Crownsville storm drain end up? In the nearest waterway or stormwater facility. Storm drains in Anne Arundel County carry runoff, untreated, to the nearest waterway or stormwater facility, and they are not connected to the sanitary sewer. Which river comes after that depends on the lot: county watershed maps split the Crownsville Census place between two rivers, the Severn and the South, while Herald Harbor and Arden on the Severn lie wholly in the Severn River watershed. ## Get a free estimate.
