If you are building a retention pond in an area that was previously undeveloped, it is important to take these factors into consideration before starting construction on one. Retention ponds and lakes need monthly prevention and planning. recommended as a means of conserving moisture and suppressing weeds. Therefore, it should be built on a slope that directs water into the pond to achieve this goal. Maintenance Retention ponds can be used in agricultural settings to collect runoff from poor permeability surfaces (such as tracks and farmyards) or as part of the agricultural landscape. Forget swimming poolswhile necessary in many communities, retention ponds can easily be considered an HOAs greatest liability and expense. The maximum slope of the safety bench shall be 6%. A pond is a type of stormwater management facility designed to collect rainwater and pollutants and prevent downstream flooding. Risk #2: Mosquitoes. Good design and adequate maintenance are likely to improve the ability to achieve high efficacy in pollutant removal. The maintenance access should Additionally, many details of cited laws are left out due to space limitations. The Flood and Water Quality Protection Manual provides guidelines and criteria for stormwater standards, detention/retention facilities, open channels, closed drainage systems, stormwater best management practices, erosion and sediment control and flood design criteria. 12. However, the inclusion of plantings, landscaping, or other features may increase these costs. Congress gives EPA authority to develop and implement federal stormwater regulations. for a liner, acceptable options include: (a) 6 to 12 inches of clay soil (minimum 10. .

A large site may necessitate several ponds divided into topographic sub-catchments. This aids in the removal of debris and sediments from water, thereby reducing pollution. All retention ponds should be built to handle the maximum amount of stormwater runoff from a given storm event. source (i.e., pocket pond). to reduce erosion. Retention ponds should be designed to reduce runoff for events as large as the drainage area's 1 in a 30-year storm (possibly larger), with excess stormwater discharged within 24 to 72 hours of the event. land application or land filling. The entire pond perimeter may be retaining walls, however, it is recommended that at least 25 percent of the pond perimeter be a vegetated soil slope not steeper than 3H:1V. Retention ponds can create a drowning hazard, especially for young children and pets. If the local government does not own it, it becomes the associations responsibility to keep the pond in working order, and they are also responsible for any expenses incurred. Retention ponds filter the water runoff that enters them on a continuous basis. Ponds should not be developed on a waste fill, uncontrolled fill, or non-engineered fill.
