In the drainage and stormwater specialty area, Civil Works Engineers has extensive experience in the preparation
of drainage reports, hydrology and hydraulic calculations, stormwater quality mitigation, storm drains and drainage
structures design, and erosion control.
Our projects have included storm drain
improvements, drainage studies, Stormwater Data Reports (SWDR) for
Caltrans projects, Standard Urban Stormwater Management Plans (SUSMP) for projects in Los Angeles County,
Water Quality Management Plans (WQMP) for Orange County
and other local agencies, and Stormwater Pollution Prevention Plans (SWPPP) required by the State during construction activities.
These projects have required familiarity with each agency's specific guidelines, calculation methods and usage of
design software including hydrologic modeling, storm drain hydraulics such as WSPG and river and/or open channel
hydraulics such as the Corps of Engineers HEC-RAS modeling.
projects encompass Orange County and other surrounding counties.
