|
WEI has designed a number of facilities relating to water quality, including ponds, hard and soft erosion control facilities, and temporary best management practice (BMP) facilities. Employees have attended and helped taught dozens of seminars on stormwater quality, erosion and sedimentation control, and best management practices. WEI has prepared stormwater quality manuals and places emphasis on environmental issues in all designs.

West Lake Detention & Water Quality, Grand Junction Drainage District, Grand Junction, CO
Analyzed and redesigned West Lake pond to be a 16 acre water quality and 13 acre feet detention basin, with automated controls to allow available pond volume to function as a first flush water quality pond for low storm runoff, flow attenuating detention basin during high storm runoff, and a fish stocked community pond during non-storm periods. Designed outlet works, controls, and backup power systems.
Mill Creek Flood Control Parkway Project (Phase 2, 4, & 5), Moab, UT
Design of concrete bike & pedestrian paths, jetties, channel improvements, creek crossing, arterial underpass, and crossing under UDOT bridges, and also permitting. Various erosion protection facilities were designed to protect improvements and mitigate scour and stream erosion and sedimentation under 100 year flows.
Water Quality Control Ponds, Mesa County, CO
As part of the Grand Valley, Combined Sewer Separation, Fruita, Orchard Mesa,and 29 Road Masterplans, recommended, sized, and provided preliminary design for 20 water quality control ponds.
Stormwater Management Manual, CO
Prepared manual used by Mesa County, City of Grand Junction, City of Fruita, Town of Palisade, and the Grand Junction Drainage District that provided several hundred pages devoted to erosion, sedimentation, and water quality design guidelines and criteria.

Redlands Grove, Mesa County, CO
Evaluated and designed channel for Colorado National Monument runoff through a subdivision. Design included HEC-11, HEC-14, HEC-15, and HDS-5 for flow conveyance, flexible lining, bend, and drop structure. Particular attention was given to erosion control on a channel having a natural gradient of 1.84% and non-cohesive soils. The design provided for a vegetated solution.
Purdy Mesa Reservoir, Grand Jct., CO
Designed reservoir spillway and riprap erosion protection down steep tailrace. State dam engineer approval was required.
Drop Structures, Moab, UT
Design of rock erosion control drop structure at 400 East St. on Pack Creek and 500 West St. on Mill Creek to protect UDOT bridges and reduce scour.
Canyon Rim Subdivision, Mesa Cnty, CO
Designed improvements to a natural channel in unstable non-cohesive soils on steep slopes at the base of the Colorado National Monument.Design focused on vegetative solution for erosion control.
Vegetation Buffers, Mesa County, CO
At many site developments, including multi-family sites, encouraged and used vegetative buffers to improve water quality prior to hard conveyance and discharge.
Powder Ridge, Mesa County, CO
Designed for runoff to pass through wetlands and sloughs to improve water quality.
