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 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
