CDOT WATER QUALITY BMP TRAINING FACILITY CONSTRUCTION PHASE and
OVERVIEW10/2009
‘This project was undertaken in connection with the settlement of an enforcement action taken by the Colorado Department of Public Health and Environment for violations of the
Colorado Water Quality Control Act.’”
CDOT WATER QUALITY BMP TRAINING FACILITY CONSTRUCTION PHASE and OVERVIEW
Project completion Oct 2009
Supplemental Environmental Project:
“ CDOT shall construct a BMP Field Training Facility (“BMP Facility”) on its property located at or near the corner of S. Colorado Boulevard and Louisiana Avenue in Denver and shall use the BMP Facility to train construction companies, contractors, consultants, municipalities, or other related organizations and individuals on the proper purpose, use, installation and maintenance of erosion and sediment control BMP’s…” Compliance Order on Consent 2009
CDOT Water Quality ProgramObjectives:Create a training venue for the construction industry to improve Stormwater Construction Permit compliance
Hands on training
Simulated real world applications
Promoting Green Government and SustainabilityComply with Consent Order between CDOT and CDPHE
Formal training to begin in Spring of 2010
CDOT Water Quality Program
Tire berm construction:
Promoting sustainability by using recycled materials
One ton compressed tire bales were used to create earth berm
Constructed slopes with sprinkler discharge allow students to see slope erosion occurring
CDOT Water Quality Program
Each compartment can be used for different erosion control application and simulated rainfall
CDOT Water Quality Program Slope construction and backfill
CDOT Water Quality ProgramCompleted berm for slope stabilization best management practice’s
CDOT Water Quality Program Water Quality Ponds
constructed to display various outlet control BMP’s, slope control and access options
Ponds capture stormwater from rain events and water used during training.
CDOT Water Quality ProgramOutlet control wall construction
CDOT Water Quality ProgramPond side slope stabilization using soil retention blankets
CDOT Water Quality ProgramFinal pond configuration and completed outlet controls
CDOT Water Quality ProgramRoadway template with
curb, gutter and curb inlets demonstrates the following:
Pavement runoff and adjacent soil runoff onto template
Type R drain and BMP’sDrainage to a Type C inlet
CDOT Water Quality ProgramRoadway template for curb and gutter, and shoulder bmp applicationsConcrete washout during construction and used in training
CDOT Water Quality ProgramConstructed roadway segment combined with curb and gutter and vegetated shoulder
CDOT Water Quality ProgramStudents can witness good and bad BMP application and installation issues
CDOT Water Quality ProgramFacility will be used to demonstrate effectiveness of various stabilization BMP’s
CDOT Water Quality ProgramConstructed ditches (2 and 5% slopes) used to simulate erosion in ditches and bmp applications
