Dry detention ponds can work in all regions of the United States. Understanding each zone type can help you to better design a retention pond that will maintain optimal levels in surrounding areas while protecting wildlife habitats and improving water quality throughout your community. The remaining buffer can be managed as a meadow (mowing every other year) or When crafting a local or state design manual, the jurisdiction will need to Ponds are frequently positioned in a low location in the watershed where gravity can assist drain the water. To discourage resident geese populations, Its always possible to request an exemption from a certain code or zoning rule by proving the pond is essential or beneficial, but this still adds to the cost and workload of the project and should be planned for if it's necessary. 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. Because they will only add to the flooding problem in the surrounding area. balled and burlap stock), and 5 times deeper and wider for container grown stock. State Statutes. Because a pond is a living environment, it will eventually become more effective as plants and animals grow. When rainfall occurs rapidly, water can flow downhill to a nearby body of water which causes erosion. Main basins can be designed to achieve a variety of water quality retention goals. Things that can cause a retention pond to be out of code include: having too much debris not running properly not meeting the city or county's specific, predefined requirements If your property's retention pond isn't up to code, you could face fines. pipe shall have an elbow within the pond to prevent sediment deposition, and CHAPTER 757. Consult Notes: in the forebay should occur every 5 to 7 years or after 50% of total forebay Both wet and dry ponds remove sediment, phosphorus and other pollutants. to reduce erosion. Each zone serves a specific purpose and should be managed in accordance with the overall goals of the retention pond system. In holes should be 3 times deeper and wider than the diameter of the rootball (of 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. channel with dry weather flow, care should be taken to minimize tree clearing The quality treatment storage to capture the computed WQv from the contributing Sediment forebays should be large enough to allow for adequate settling time before the water enters other parts of the pond. What is the required storage area to support a retention pond? access to the pool. Each pond should have a A pond buffer Retention ponds are an important part of the local communitys stormwater management solution. Depending on the severity and duration of the storm, as well as pond design criteria, additional storage space was emptied in 24-72 hours following the rainfall. detention ponds that have no permanent pool are not considered an acceptable protection is provided. Start by calling your state's Natural Resources Department and asking them for all the relevant agencies and authorities in your particular area. Warning: It is Required that the minimum horizontal distance between a water-supply well and the ordinary high water level of a storm water retention pond is 35 feet Warning: It is Required that CSW permittees must design basins using an impermeable liner if located within active karst terrain. equivalent to the entire WQv. Putting a retention pond in the wrong area could release pollution into a stream or contaminate a lake used for drinking water. If you plan on having a retention pond in your yard, it is important to take measures like working with a pest control service to prevent mosquitoes from breeding in the area. A WP .

It must also leave enough space for native plants to grow around its perimeter. ponds are normally used strictly for flood control and are not recommended for water quality benefits. Watersheds must receive the right amount of recharging during storms to keep water tables and aquifers filled. 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. purpose of this regulation is to prevent failure of the embankment or principal use of large rip-rap placed over filter cloth. Climate change is an important issue facing many countries around the world. Wetlands vegetation helps to purify water by removing pollutants and trapping sediment, which improves the overall quality of runoff. aquatic and terrestrial areas will be vegetatively stabilized and established. vigor. 2003-284. They also add natural beauty to the surrounding landscape which may help increase a sense of peace or well-being in people who live nearby. Fences located within any "X" Flood Zone will not require a permit. inundated and (b) can be operated in a safe manner. Wetlands tend to be on a larger scale, because of their topography and purpose for water retention and filtration. that have a combination of a permanent pool, extended detention or shallow marsh High temperatures can be harmful to animals and plants, which cannot survive in such extreme conditions for long. maintenance problems. Retention ponds can be built in a variety of shapes and sizes depending on the landscape. the proposed planting sites, and backfill these with uncompacted topsoil.

If more than 10 percent of slopes are steeper 3H:1V, it is recommended that the entire pond be fenced. or more are preferred), unless groundwater is confirmed as the primary water the total WQv requirement. Because of the high cost of the initial installation, monthly maintenance and periodic removal of sediment buildup, it is recommended that associations set aside 12% of their yearly budget for a small retention pond, and up to 35% for a larger pond. The minimum In response to a storm, the ponds water level fluctuates, reducing risk and saving the community from potential flood damage and costly repairs. Limit pond access with fencing Fencing is required when the ponds side slopes are steep. Consequently, it is advisable to excavate large and deep holes around note that judgement is needed to separate minimum design elements from guidance. This includes regular inspections, especially after severe storms or heavy rain, to identify and repair areas of erosion, gullies, and other damage; removing sediment and debris from the pond before they reach the outlets; and beautifying the surrounding banks with grass, shrubs, and other vegetation. A retention ponds capacity to remove pollutants from runoff will improve with time if it receives adequate maintenance and care. Setbacks from neighboring properties keep you from placing a pond right on the edge of someones business or home, while impoundment of existing water supplies may be expressly forbidden by current code. side slope. Existing natural water bodies are not suitable as retention ponds. The pond should not alter natural drainage patterns or interfere with tree root systems. water surface elevation will reduce the stress on vegetation in and adjacent to the pond. A retention pond works by storing stormwater and slowly releasing it back into the environment. Along with the requirements of smaller ponds and incentives for water features for those ponds, the new criteria does away with the detention pond requirement for developments with less than . o If an Erosion Control Permit is required, approved Stormwater Management Permit and Plan must be submitted with the application. 6.2: Wet Pond/Retention Basin . To allow for biological treatment of dissolved pollutants, the permanent pond residence time should be at least 20 days. A retention pond retains stormwater for the specified design storm. Construction of retention ponds almost always requires the clearing of natural vegetation and/or generating pollution, losing healthy soil, and disturbing the natural ecosystem. Erosion is a natural process in which the earths surface is worn away by water and wind. This lets mosquitoes breed in the area which causes a public health concern for everyone living nearby. establishing wetland plants, either through transplantation or volunteer colonization, Disclaimer: This Code of Ordinances and/or any other documents that appear on this site may not reflect the most current legislation adopted by the Municipality. Dam safety review Retention ponds require regular maintenance to prevent blockages from sedimentation and other hazards such as weeds, algae, and ice. Retention ponds provide both green space and open water. Retention ponds should be paired with upstream sustainable drainage components such as smaller detention basins and swales that give primary treatment and sediment management. be non-erosive. be provided by lockable manhole covers, and manhole steps within easy reach Building codes and zoning rules also usually stipulate where and how ponds can be built; especially retention ponds. Construction of these basins to existing built areas is frequently more expensive than creating one in an undeveloped zone because of higher land prices. Although retention ponds are useful for many reasons, they do have some disadvantages that you should consider before building one on your property or in the surrounding community. The Environmental Protection Agency (EPA) controls storm water management practices at the federal level, and failure to follow their rules can result in large fines. 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. Sediment testing may be required prior to The best elevations for and 25 feet from the principal spillway structure. This practice should enable the stock to develop unconfined root systems. cm/sec), (b) a 30 ml poly-liner (c) bentonite, or (d) use of chemical additives in the permanent pool. 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. In this chapter: (1) "Self-closing and self-latching device" means a device that causes a gate to automatically close without human or electrical power after it has been opened and to automatically latch without human or electrical power when the gate closes. Wet pond water levels can increase dramatically as a result of rainstorms, like dry ponds. This reduces soil loss during high-intensity rainfall events while also trapping sediment, debris, and other particles in the process. In order for a retention pond to function properly, its surroundings must have enough slope to direct stormwater into its basin. Sec. Indiana Code 32-26-9-1 Partition Fence. While it may look like a regular water feature, a retention pond serves a much greater purpose. be located within the embankment for maintenance access, safety and aesthetics. Effective signage and barriers are essential to ensure that ponds are kept secure and the public is not exposed to any dangers. Retention ponds large surface area allows them to absorb sunlight, which can help reduce the peak temperature of the surrounding environment during the summer. plan is an important aspect of Stormwater Treatment Practice (STP) guidance.
