Download Complete Report (4.58 M) The amount of water that a retention pond can store is determined by its storage capacity and infiltration rate. Inlet areas should be protected Ponds have an embankment (called a dam) to hold back water that is entering the pond. Retention ponds prevent pollution by trapping sediment, debris, and other particles that are being carried along in the water before they can reach nearby waterways. Every DOT retention pond is enclosed by a 6-foot chain-link fence with a locked gate, Batterson said. Because a pond is a living environment, it will eventually become more effective as plants and animals grow. Therefore, it should be built on a slope that directs water into the pond to achieve this goal. Currently, the St. John's River Water Management District says only ponds with side slopes steeper than four feet horizontally by one foot vertically are required to be fenced off or restricted. cm/sec), (b) a 30 ml poly-liner (c) bentonite, or (d) use of chemical additives which does not cause erosion. 2003-284. The to a pond or wetland that has such a small contributing drainage area that little To protect public safety and maintenance access, slope angles should not exceed 1:3. Please 12 feet or greater. are necessary in all cases. City records as far back as January show at least 10 complaints citing broken barriers and fences surrounding retention ponds, though it's not clear if all the complaints involved city-managed . Main basins can be designed to achieve a variety of water quality retention goals. A pond is a type of stormwater management facility designed to collect rainwater and pollutants and prevent downstream flooding. on erosive velocities. Table A drainage system that is poorly designed and maintained can lead to the pond overflowing and causing flooding in nearby areas, which can be both messy and dangerous. Sediments excavated from To make sure your drainage system is in good working order, have a professional inspect it regularly. For sites that do not have an outfall, the pond volume will be based on a 100 year 10-day . Inlet pipes to the pond Health implications of open water places must also be considered, particularly in warmer locations where ponds may provide a favorable ecology for mosquitoes, which can be linked to increased disease transmission. However, this should not be done until the water quality is tested and found to be healthy for aquatic life. Cranberry Township wants to inform the homeowners how to properly maintain your ponds. It is designed to prevent flooding, prevent erosion, and improve water quality. "If you have an area that's close to children, you would want to have a fence there to keep out young. Pursuant to the Coastal Zone Management rules at N.J.A.C. The drainage area required to support a retention pond can be as tiny as 0.03-0.1 km2 (Environment Agency, 2012), or even smaller if the retention pond is connected to another source of water, such as a spring. The soil beneath the pond should be sufficiently impermeable to prevent it from drying out. A wetland is an ecosystem that contains both terrestrial and aquatic plants. When rainfall occurs rapidly, water can flow downhill to a nearby body of water which causes erosion. A fence is a barrier to mark a boundary; such a barrier can be made of posts and wire or boards. Ord. Water quality storage can They assist the landscapes ability to retain water in the event of a flood and, by slowing down runoff, make this water accessible for other uses (such as water to sustain aquatic and riparian ecology in and around the pond), though they are unlikely to be big enough to store water for significant human usage. While these regulations are set at the federal level, its up to each state or county to implement them in a specific area. Produced biomass can attract wildlife and help with small-scale bioenergy production. be at least 12 feet wide; have a maximum slope of no more than 15%; and should Retention ponds can provide both stormwater attenuation and treatment. The water quality of your pond should be tested regularly to make sure it does not have high levels of nitrogen or phosphates, which are toxic to fish and other aquatic life. Whatever your project needs, let BTL custom build to your exact specifications. It is also important to consider the location of the outfall and to design so that it is clear of structures, trees, or other obstacles. In addition, it will provide additional benefits such as water storage and wildlife habitat. The official printed copy of a Code of Ordinances should be consulted prior to any action being taken. However, typically 3 7% of the upstream catchment area will be necessary as the baseline. and should be 4 to 6 feet deep. A well-designed retention pond will offer a high level of stormwater treatment, which will improve the water quality before it is released back into the environment. The permanent pools depth should be between 1.2 and 2 meters. American Legal Publishing and the jurisdiction whose laws are being translated do not vouch for the accuracy of any translated versions of such laws. land development code of seminole county, florida; supplement history table; chapter 1 - general provisions; chapter 2 - definitions; chapter 5 - administration left in trees to discourage resident goose populations. A larger pond will have a higher water quality because changes in water chemistry will be slower. Sediment testing may be required prior to A stilling basin Retention ponds are important projects that require planning and approval from multiple agencies on the federal and state levels. Here are some of the primary benefits of retention ponds. Larger retention ponds (volumes more than 25,000 m3) necessitate extensive impoundment and may be subject to additional inspection and structural restrictions. High temperatures can be harmful to animals and plants, which cannot survive in such extreme conditions for long. For above ground pools: If the sides of the pool are 48 .

Freshwater ecosystems are at risk from many changes to the environment. Forget swimming poolswhile necessary in many communities, retention ponds can easily be considered an HOAs greatest liability and expense. that extends 15 feet outward from the normal water edge to the toe of the pond This is why its important for the pond to have a drainage system in place that will help prevent standing water or overflow. Depending on the design requirements for each retention pond system, the outflow structure should include both of these elements. The outfall structure governs how water flows from the main basin into the retention pond systems downstream sections. For wildlife ponds: the slope should be 10:1 or greater, average depth should be 2-3 feet, and the maximum depth 6 feet or less. SAFETY. If the underlying soils are permeable, a liner or other impermeable material, such as puddled clay, will be necessary to prevent the pond from drying out or if the soils are particularly prone to contamination.

The Pennsylvania Department of Environmental Protection (PA-DEP) has mandated that every municipality inspect all detention and retention ponds annually. Size: The size of a pond or wetland is variable. Design Criteria: Stormwater Ponds. establishing wetland plants, either through transplantation or volunteer colonization, Ponds should not be developed on a waste fill, uncontrolled fill, or non-engineered fill. A two-stage pond contains a water quality volume in the lower stage, and has an upper stage for detention of larger storms for flood control. plan for a stormwater pond and its buffer should be prepared to indicate how There are no particular restrictions on the maximum drainage area for retention ponds, though 3-7% of the upstream catchment area is normally required for the pond (CIRIA, 2007). Ponds can help to increase property value because they add an interesting outdoor feature that can be used for recreation and enjoyment. Building codes and zoning rules also usually stipulate where and how ponds can be built; especially retention ponds. FARM PONDS The NRCS is available to assist farmers with planning and designing farm ponds. This happens when the water becomes stagnant and the mosquitoes find it as a suitable breeding ground. This keeps pollutants and other contaminants out of downstream waterways, where they can degrade water quality over time. 150.18 SWIMMING POOL AND DETENTION/RETENTION POND FENCE REQUIREMENTS. If your drainage system is damaged or poorly maintained, then water can accumulate and become stagnant instead of draining properly. Weve worked on hundreds of retention pond projects and can help guide you through the liner selection and installation process.

Not only do they pose a constant drowning hazard for residents, but they also require continuous maintenance and planning. stormwater runoff. If the surrounding land is not properly sloped, stormwater may have difficulty entering the retention pond. In response to a storm, the ponds water level fluctuates, reducing risk and saving the community from potential flood damage and costly repairs. Effective signage and barriers are essential to ensure that ponds are kept secure and the public is not exposed to any dangers. 757.001. As a result, lowering the temperature helps to prevent overheating problems from developing over time. Retention ponds provide an excellent defense against landslides because they prevent the rapid flow of water over a large area. Each pond should have a Therefore, it is important to build it with the appropriate size so that it will not overflow during heavy rainstorms. 6.2: Wet Pond/Retention Basin . that extends up to 15 feet inward from the normal shoreline and has a maximum And here is why A small retention pond can cost over $30,000 to remove sedimentation every 10-15 years after it is only 50 percent full.

Ponds should be positioned in non-intensively managed settings where native flora is already developed and/or will thrive, whenever possible. The depths of retention ponds vary, but they can be as deep as 30 feet (9 meters). Theyre also very attractive to look at, and if well-designed, they can even become the propertys focal point. The or no baseflow is available to sustain water elevations during dry weather. Any pool used for swimming or bathing over 24 inches in depth or with a surface area exceeding 200 square feet. Stormwater runoff has the potential to contaminate nearby waterways. shallow areas of the pool itself. Retention ponds may be built on an artificial surface, depending on site stability. This aids in the removal of debris and sediments from water, thereby reducing pollution. Because stormwater runoff can carry significant amounts of sediment and chemicals into these ponds during heavy storms. The spillway is a controlled release path that is used to manage the flow of stormwater runoff downstream during major rainstorms. Detention ponds simply slow down water that eventually drains off into creeks, rivers, or surrounding ground. Wetlands vegetation helps to purify water by removing pollutants and trapping sediment, which improves the overall quality of runoff. Fences. However, the inclusion of plantings, landscaping, or other features may increase these costs. may be hardened to make sediment removal easier. This lets mosquitoes breed in the area which causes a public health concern for everyone living nearby. It is desirable to locate Retention ponds should have variable pond depths (rather than a flatbed) and some areas of the pond should be shaded.

A preferred Outfalls should be constructed Retention ponds can be built in a variety of shapes and sizes depending on the landscape. This volume generally depends on the required time to provide full capacity, which is dependent on the drainage area and rainfall intensity. Above this permanent pool of water, wet detention basins are also designed to hold the runoff volume required by the stormwater regulations, and to release it over a period of Infiltration basins are located at the end of retention ponds before the water flows downstream. To discourage resident geese populations, Please contact the Harnett County Planning Department at (910)893-7525 option 4, or NC DENR at (910)433-3300 or (919)733-5083 with any questions. Stormwater management facilities are designed to collect and control runoff from precipitation that falls on the land. the proposed planting sites, and backfill these with uncompacted topsoil. Retention ponds also help gradually recharge groundwater levels by recharging the groundwater aquifer with rainwater. be preserved in the buffer area during construction. Both the WQv-ED A retention pond can trap these contaminants in the water to some extent before they are released back into the environment. 2. A retention pond can be designed to mimic some features of a natural wetland by including various types of wetlands vegetation as part of its design. to reduce erosion. Stormwater is responsible for "functional maintenance" of over 460 retention ponds throughout the County. Retention ponds help reduce flooding by slowing runoff. To avoid this, a well-designed spillway should be installed to help manage the flow of stormwater runoff downstream. Potential buyers should be aware of who owns the pond and how well they protect their investment before moving in. Fence area and post with warning signs if trespassing is likely. These studies will typically cost $3000 to $15000 depending on the scale and depth of investigation. 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. In agricultural areas, the pond should be designed to prevent livestock from falling in and drowning. . If more than 10 percent of slopes are steeper 3H:1V, it is recommended that the entire pond be fenced.
