Homes, developments and commercial buildings alter the land, and the natural permeable system of forests and grasslands gives way to hard surfaces like roads, roofs, sidewalks and parking lots that increase rapid rainfall runoff. Erosion can be a problem, and pollutants from sediment, nitrogen and phosphorous, oil or gasoline off of roads, bacteria from pet waste and plant litter can all impact metro-Atlanta water systems and their native wildlife.
As a result, retention ponds are a Best Management Practice (BMP) for storm water and are designed to reduce the impacts of excess water and pollutants caused by increased building and development of new construction.
In Georgia, Homeowners Associations (HOA’s) and Property Management Companies are required to maintain retention and detention ponds to make sure that rainwater is collected without disturbing the surrounding land. Ponds are subject to annual or semi-annual inspections. However, these retention basins last longer when they are properly maintained. For the best in maintenance help, turn to Crabapple LandscapExperts, a full service maintenance company equipped to handle all aspects of retention pond maintenance and restoration.
A retention pond is self-enclosed and depends on evaporation and percolation to remove water, and differs from a detention pond that has an outlet such as a neighboring storm sewer or creek to accept excess rainwater and storm water after a rain event. Count on Crabapple LandscapExperts for regular inspections and maintenance of your pond in order to:
- Protect life and health
- Minimize property damage
- Protect water quality
- Maintain a functional storm water system
Crabapple High-Level Maintenance includes:
Inspection of riprap (large rocks used to slow the flow of water) and replacement when clogged with sediment or debris
Vegetation management including elimination of invasive species and increase in native plant diversity
Embankment and outlet stabilization, where we establish permanent native vegetative cover on eroded slopes
Debris and litter control and routine inspections for trash or debris that could block inlet or outlet pipes, grates, culverts or emergency spillways
Wildlife and insect control, for example, use of natural predators that are encouraged by wildlife enhancements, by physical means such as low barriers to stop nuisance geese, or by state sanctioned West Nile Virus control for mosquitoes (through local city and state health departments)
Sediment removal and dredging may be required, typically once every 5-10 years
Maintenance of a 15-25 foot no-mow and pesticide-free zone, eliminating herbicides, insecticides or fertilizers around pond, and burning off vegetation once each spring
Recycling of yard waste such as grass clippings, leaves or brush that is carried away and recycled to rich mulch at the Alpharetta Crabapple facility
