A retention pond can make a significant impact on the environment especially if it is in an undeveloped area. Retention ponds are permanent structures designed to hold water flow for a short period of time, similar to a dam. (WQv-ED) or marsh. The principal They can also improve biodiversity in an area while providing a habitat for many organisms that cannot survive in open areas without major changes. 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. To prevent vandalism, the Construction of retention ponds almost always requires the clearing of natural vegetation and/or generating pollution, losing healthy soil, and disturbing the natural ecosystem. to sustain a permanent pool of water.

Building codes and zoning rules also usually stipulate where and how ponds can be built; especially retention ponds. Plants and trees help to remove CO from the atmosphere through photosynthesis, which absorbs C02. Warning signs prohibiting The Pennsylvania Department of Environmental Protection (PA-DEP) has mandated that every municipality inspect all detention and retention ponds annually. This keeps pollutants and other contaminants out of downstream waterways, where they can degrade water quality over time. When built with longevity and maintenance in mind, these ponds can enrich an entire ecosystem by creating man-made wetlands with the same benefits as natural ones. plan. left in trees to discourage resident goose populations. These rules were developed in the early 90s to help guide states and counties looking to improve their runoff management plans and reduce pollution. Requirements.

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. such that they do not increase erosion or have undue influence on the downstream Fencing of ponds is not This is especially a bigger concern for smaller ponds that are not capable of sustaining a certain type of water quality and nutrient balance that is necessary for the survival of these species. For above ground pools: If the sides of the pool are 48 . recommended as a means of conserving moisture and suppressing weeds. The soil beneath the pond should be sufficiently impermeable to prevent it from drying out. Theyre also very attractive to look at, and if well-designed, they can even become the propertys focal point. The design should also consider the safety of those who may be working on-site, as well as any nearby residents and property owners. The purpose of this zone is to allow for additional filtration processes so that the water quality entering surrounding areas remains high. This lets mosquitoes breed in the area which causes a public health concern for everyone living nearby. A pond buffer should be provided that extends 25 feet outward from the maximum water surface elevation of the pond. This means that youll need to secure impoundment rights for a stream, creek, spring, or other natural body of water. in providing ample space for access and safety. Retention ponds need to be secured with 6-foot barbed wire fencing and posted with regulatory signs for the safety and protection of people, motorist and pets. If youre building a retention pond in an area with absolutely no building codes or restrictions on land alterations, you may not have to follow the Phase I and II requirements from the EPA.

In order to ensure that a retention pond is effective in trapping sediment and pollutants, the sides of the basin should be steep and sloped at a rate of 3:1. The maintenance access should Pond owners have unique responsibilities in terms of stocking, maintenance, and liability requirements. For example, there is a constant danger of drowning for families with young children. When water enters a retention pond, it flows over an outfall structure, which regulates how fast and in which direction it flows downstream. ponds are normally used strictly for flood control and are not recommended for water quality benefits. Because a pond is a living environment, it will eventually become more effective as plants and animals grow. Stormwater is a major concern because if not properly handled, it can lead to flooding, erosion, and pollution of neighboring water bodies. 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.
