The Elements Of Erosion Control Colorado

There are city, county and state laws dealing with erosion control Colorado. Most mandate that there be control and containment of erosion and sediment on any construction site over an acre in size or that is located on a slope or hillside. The goal is to contain any contaminants that may arise from the construction process and the equipment used to create the site.

Most construction requires clearing of all vegetation prior to beginning the actual work of erecting any type of building. The state and county agencies require that permits be acquired and plans submitted detailing the methods that will be used for controlling the sediment and run off from the site. There are regular inspections made by city or county agents to insure compliance. Any breach of the containment must be repaired immediately to avoid fines or litigation.

Rain, wind and running water are all erosive forces. The elements of nature can cause gulleys, silt build up in water ways, and slippage of land that is on an incline. In an effort to prevent this damage, contractors and state agencies work together to replant these areas as quickly as possible.

Road construction commonly uses straw blankets to stop or slow the erosive tendencies that come with ongoing traffic. Oils and other contaminants collect on the roadways and are washed to the sides when it rains. The blankets help to contain the contaminants and as they return to nature act as a natural fertilizer. The straw is held in place by a biodegradable webbing to prevent straw from being blown or washed away.

Hydro processing is a method of covering and reseeding areas of exposed soil. The mulch that is used contains a gummy substance that adheres to the soil to prevent erosion from occurring. The mulch is comprised of paper, wood pulp and aspen hydro mulch. When the grass seeds are added to the mixture they also put fertilizer with it. The combination of these resources helps to guarantee fast and near total germination for the area.

Many times native flower seeds are added to the mixture if large areas are to be covered. This is especially important for hill sides and wilderness areas. Indigenous grasses are also used with hydro seeding large areas because they survive in sun or shade and require very little water.

Another method of planting vegetation in areas where grading or other construction has taken place is drill seeding. This reseeding process uses a tractor to furrow the soil and a special device to plant the seeds into the soil. This method is less expensive than other types of treatments and creates higher growth ratio because the seeds are below the surface and not foraged by birds and rodents. The seeds are also safe from wind and sun damage that can prevent seed germination.

Re-vegetation is an intricate part of returning the ecosystems to their natural state. It plays a role in sustaining the erosion control Colorado format. Only by helping to reinstate the original conditions found when the area was first graded can the state and cities claim to be working towards an itinerary designed to restore the area to a pre-disturbance state of being.
