A flood plain is the area adjacent to a river, creek, lake, stream, or other open waterway that is subject to flooding when there is a significant rain.
Flood plains can be entirely within the waterway.
As more lots are covered with more buildings and parking lots, the amount of water that flows into creeks and lakes increases because there is less vegetation to absorb the water when it rains. If the City or private property owners install flood controls or detention ponds, the amount of water going to creeks and lakes is reduced. You must also file a plot plan and submit building plans that shows compliance with all flood plain regulations as well as other City standards. When your site plan and building permit applications are approved, you can request a pre-construction conference and then begin constructing the improvements and requesting inspections. All construction that is allowed in flood plain areas must have the lowest floor elevation at least one foot above the 100-year flood plain.
