There may be. County stormwater records list 391 stormwater practices in Riva, and 260 of them are dry wells or infiltration trenches. One record is one practice, not one house, so look through the papers for your own lot. If you know where yours is buried, say so in your estimate request. ### Is every Riva street on public sewer? No. The county plan lists parts of Riva among the areas not served by public sewer. If your lot has a septic tank and field, say where they are when you describe the wet spot, before any rock is planned. ### The stream behind my Riva yard is eroding. Is that yard drainage? No, that is stream work, a separate trade. County restoration records list a Beards Creek stream restoration at Breckenridge Way in Riva as complete in 2021. Arundel Rivers Federation, which calls that job its Annapolis Landing Stream Restoration, says it stabilized an eroding stream with wood-based structures and reconnected it to its floodplain. Our part stops at the yard: rock that moves rain across it. ### How often has Central Avenue flooded at Beards Creek? On at least five dates in NOAA's files. NOAA's Storm Events Database has flood reports filed under Riva on five dates from May 2018 to July 2022 in which Central Avenue, MD 214, flooded or was closed at or near Beards Creek. For July 16, 2022 the reports say Beards Creek was out of its banks, Central Avenue was closed by swift moving water and a vehicle was stranded in high water at the creek. Those reports are about a road crossing; NOAA holds only what was reported to it. ## Get a free estimate. Give the Riva street, where the water sits and which way it runs off.
