Covington sits just 26 feet above sea level where the Bogue Falaya and Tchefuncte rivers wander toward Lake Pontchartrain, and that low, water-shaped ground defines every yard here. Silt loam left behind by centuries of river flooding drains reasonably well until the 65 inches of annual rain arrive in Gulf downpours, at which point beds along the Bogue Falaya Park corridor and the older streets near downtown can hold standing water for days. Zone 9a heat pushes azaleas, camellias, and live oaks hard, so pine straw and shredded hardwood get consumed fast and need honest replacement rather than a light dusting. We haul the same washed river gravel and screened topsoil across the Northshore to Lacombe, Ponchatoula, and Hammond, and out toward Bogalusa and Picayune, because the drainage problems do not stop at the parish line.
