While it may look like a regular water feature, a retention pond serves a much greater purpose. land development code of seminole county, florida; supplement history table; chapter 1 - general provisions; chapter 2 - definitions; chapter 5 - administration This can be done by regularly removing any excess plant growth, adding additional aeration devices to improve circulation and oxygen levels, and removing any dead animals that may have accumulated around the pond. Therefore, it is important to manage stormwater using the right tools and techniques. However, they should always have enough space to store stormwater runoff and slowly release it downstream while maintaining nearby water levels. This lets mosquitoes breed in the area which causes a public health concern for everyone living nearby. note that judgement is needed to separate minimum design elements from guidance. Runoff from each rain event is detained and treated in the pool. This happens when the water becomes stagnant and the mosquitoes find it as a suitable breeding ground. Performance is enhanced when multiple treatment These documents should not be relied upon as the definitive authority for local legislation.
