Erosion Control Techniques for Homeowners

Erosion in Florida is typically caused by rain, storm, or flood waters passing over land. The result of erosion is often steep banks of scoured soil or other ground material. It’s important to remember that erosion cannot be controlled while it is happening and is often not seen until the flood waters have subsided.

Jacksonville erosion controlThe most costly problems associated with erosion is when the loss of soil or other materials undermines structures, leading to major failures occurring most often when waters flow rapidly over loosely compacted soil or denuded slopes. Other say the environmental impact of erosion is the main long-term problem occurring when contaminants and other human impacted chemicals and fertilizers find their way to our lakes, ponds, rivers or streams. It contributes to the phosphorus load and can result in algae blooms and other concerns. This can be very hazardous to fish and other wildlife.

Soil erosion costs Florida homeowners millions of dollars a year. Soil loss not only causes damage to roads and property but In addition, the soil removal from roadside ditches and storm drains is required, costing taxpayers money. The environmental cleanup can be costly also.

What can we do on a homeowner level? Becoming familiar with the natural drainage patterns of your property and trying to avoid adversely altering them. Proper site design will help you avoid expensive erosion control measures. Plan to preserve existing vegetation as much as possible. Vegetation will naturally curb erosion, improve the appearance and the value of your property, and reduce the cost of landscaping later. Wide buffer strips of undisturbed vegetation are often required along stream and lake shores. You should be cautious when using heavy machinery in these buffer areas. 

Discuss clearing limits with your contractor in advance. Field mark these limits with ribbons or flagging. Flag particular trees and shrubs that you want protected. Remember that heavy machinery must be kept well away from trees to avoid compacting their roots; otherwise, they may die a few years later. Trees roots can also smother if excess fill is re-graded around them. When the earth moving is completed, replant any disturbed areas immediately - consider groundcovererosion control Jacksonville backyard Florida Moderna native to northeast Florida such as perennial peanut or other local native groundcover these are generally better at taking up pollutants and nutrients in storm runoff water. Use your soil test results to determine fertilizer and lime needs. Be extremely careful when using fertilizers near streams, lakes and ponds. Consider using organics and be cautious of applying prior to a storm. You should also use formulations very low in phosphorus in areas with any possibility of runoff into local waterways. Be cautious of diverting water into your neighbors’ property or public lands.

Erosion Control Pavers Jacksonville

The use of pavers for erosion control in north Florida is growing on both a commercial and a residential level.  Permeable or pervious pavers can reduce or eliminate storm water runoff, decrease flooding and relieve sewer systems ­ yet provide a sturdy pavement for vehicular traffic. In addition, the erosion control pavers can permit the creation of a lush, green landscape by controlling the runoff and preserving the soil.

Erosion Glossary

Abrasion: the removal of streambank soil as a result of sediment-laden water, ice or debris rubbing against the bank.

Absorption: the process by which a liquid is drawn into and tends to fill permeable pores in a porous solid body, also, the increase in mass of a porous solid body resulting from penetration of a liquid into its permeable pores.

Accelerated erosion: erosion caused or increased by human activity, such as agriculture or construction, as opposed to naturally occurring erosion.

Aerification: a mechanical process used to cultivate the soil without destruction of the turf.

Backfill: the process of filling a cavity with soil, gravity, rock or other material.

Bank: the part of the soil next to a stream, lake or body of water where the soil elevation adjacent to the water is higher than the water level; also embankment.

Bank slip: downward slippage of the bank of a stream or body of water caused by erosion and stress.

Blanket: material placed on soil or a streambank to cover eroding soil.

Buffer strip: a small area of permanent vegetation to protect the soil from erosion, slow water runoff and trap sediment and other pollutants.

Cohesive soil: microscopic soil particles that have natural resistance to being pulled apart at their point of contact.

Compaction: the pressing together of soil particles into a more dense mass.

Distressed streambank: a bank experiencing erosion or failure.

Dredge material: soil that is excavated from a stream channel, lake or other body of water.

Erosion: the removal of soil particles by wind, water or other natural agents.

Erosion control blanket: blanket made from a natural or synthetic material and enveloped in netting to stabilize disturbed or highly erosive soils while vegetation is established.

Face planting: planting vegetation in the frontal openings of retaining structures.

Field capacity: the amount of water a soil can hold.

Fill material: soil, rock, gravel or other matter that is placed at a specified location to bring the ground surface up to a desired elevation.

Groundwater flow: water that moves through the subsurface soil and rocks.

Impermeable material: a soil or material whose properties prevent movement of water through the material.

Impervious surface: hard ground cover that prevents or retards the entry of water into the soil and increases runoff.

Infiltration: the portion of rainfall or surface runoff that moves downward into the subsurface rock and soil.

Loam: an easily crumbled soil consisting of a mixture of clay, silt and sand.

Microscopic soil particles: clay and silt; particles that cannot be observed by the unaided human eye.

Mulch: any material used to cover a soil surface to reduce evaporation or prevent erosion.

Noncohesive soil: soil particles that have no natural resistance to being pulled apart at their point of contact, such as silt, sand and gravel.

Palisade: a barrier.

Pervious or permeable paver: a paver that allows water to pass through.

Plugging: establishing turfgrass using plugs of sod.

Rapid drawdown: lowering the elevation of water against a bank or wall faster than the structure can drain, leaving a pressure imbalance that may cause the bank or wall to fail.

Renovation of turf: improvement usually involving weed control and replanting into existing live and/or dead vegetation; does not encompass reestablishment.

Retaining wall: a wall that holds back earth or water.

Revetment: a facing of stone, bags, blocks, pavement, etc. used to protect or armor a bank against erosion.

Rill erosion: removal of soil particles from a blank slope by surface runoff moving through relatively small channels; the most common form of erosion.

Riprap: a layer, facing or protective mound of stones, randomly placed to prevent erosion or scour at a structure or embankment.

Scour: the erosive action of flowing water in streams that removes and carries away water material from the bed and banks.

Sediment: soil particles that have been transported away from their natural location by wind or water action.

Sediment deposition: the accumulation of soil particles on the channel bed and banks.

Sediment load: the soil particles transported through a channel by streamflow.

Sheet erosion: the removal by surface runoff of a fairly uniform layer of soil from a bank slope.

Sloughing: movement of a mass of soil down a bank into the channel, similar to a landslide.

Surface runoff: the portion of rainfall that moves over the ground toward a lower elevation and does not infiltrate the soil.

Tillage: the practice of producing a rough soil surface to maintain surface residue, conserve soil moisture and reduce wind erosion.

Water erosion: removal of soil particle by water; the three types are sheet erosion, rill erosion and gully erosion.

Weephole: opening left in a revetment or bulkhead to allow groundwater drainage.

Wind erosion: the removal of soil particles by wind, causing dryness and deterioration of soil structure; occurs most frequently in flat, dry areas covered by sands and loamy soils.
