Description

The stormwater drain at 405 Waverly Hall Drive, accepting runoff from a significant part of Waverly Hall Drive, a cul-de-sac, and from backyard drainage on other side of street, is causing significant damage to my property, where it flows into the protected waterway in the backyard. With the recent rains - the problem has become extremely dangerous - with the washout now being approximately 10 feet wide, and about 40 feet long, and eroding away part of the landscaped backyard. The cause of the issue is a 24 inch culvert coming off the street, that is dumped out approximately 100 feet off the street, and 130 feet from the creek. While the homeowner has attempted to channel the flow, as well as exercise some level of erosion control, the homeowner can not be expected to manage a multi-thousand gallon per minute outflow of water that fills the pipe to full capacity. Today is not the first time there has been an issue. In the past the extensive flow has even jumped the banks of the channel that has created, and flowed directly across the backyard to the creek. But the more it has eroded and deepened, it now does not flood across the backyard, but rather is washing away a tens of cubic yards of soil into a protected waterway. I realize Roswell states that all waterflow downstream of the culvert is the responsibility of the homeowner, but I believe in this case, the volume of water is too extensive for homeowner management. The first issue is the large length of road and area the pipe is being asked to handle, and may require re-engineering by the city so the outflow is more reasonable and properly handled. Second, because the ending point of the outflow from the culvert (approximately 130 feet away) is in a protected waterway, the Fulton County Protected Stream regulations prohibit the homeowner from taking any action which disturb the soil, grade, etc., within 25 feet of the protected waterway. I respectfully request the city to inspect, with the homeowner present. Please feel free to call me at 425-205-1854 to set up a time at your earliest convenience.
