Types Of Erosion Control Colorado

By Marissa Velazquez


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.

Straw blankets and wattles are used to protect the bare earth by many contractors prior to completion of their project. These blankets have a netting to keep the straw from blowing away and some are as wide as one hundred feet. They are used along highways that have no grass or ground cover to protect them. The straw covers eventually break down and become fertilization for the grasses that germinate in the spring.

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.

The contractors will often put wild flower seeds from the surrounding area into the mixture being sprayed onto open areas. The flowers have deeper root systems and regenerate themselves every year. This serves to help assure that the prevention measures will not have to be repeated. Many contractors search out the grasses that are indigenous to the area and use them to bind the new ground covers with the old.

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.
