Construction Best Management Practices(Sediment and Erosion Control)

Site Restoration of Xcel Energyís Sulphur Substation (Example Project)

Xcel Energy
Town of Parker, Colorado
Site Restoration

In spring, 2005 some of the vegetation outside the fence started to die off. The cause of the die-off is suspected to be linked to soil sterilants and/or herbicides that were applied during and after construction.

JFSA was contracted to: 1) determine the specific reason for the die-off; 2) propose solutions for restoration; and 3) identify changes in design or operations to prevent this problem on future sites. JFSA conducted specific soil analysis, rainfall measurements, determined all variations with the design that resulted in re-grading of the on-site detention pond, soil erosion measures such as Turf Reinforcement Mats and subsequent approval for a Grading and Erosion Control Permit.

Objective:
  • Determine specific reason for the die-off of surrounding vegetation following heavy rainfall
  • Propose solutions as to how to restore the site
  • Identify changes in design or operations to prevent this problem on future sites
Important Features:
  • Conducted specific soil analysis and rainfall measurements and determined all variations with the design
  • Cause of the die-off suspected to be linked to soil sterilants and/or herbicides that were applied during and after construction and migrated offsite following heavy rainfall
  • Recommended turf replacement mats for erosion control and regraded detention pond to increase flood storage
  • Applied for a Grading and Erosion Control Permit, which was approved
