WRECO Takes the Water out of Napa Airport
December 2006

Napa Airport Figure

To identify the source of flooding at Napa County Municipal Airport, WRECO was selected to conduct a holistic evaluation of airport drainage. WRECO is completing this task by assessing the entire site. This includes analysis of: the drainage basin, on-site facilities, on-site and off-site detention systems, and tidal impact on local water bodies. WRECO's final report will offer multiple options to remedy existing and potential flooding issues.

WRECO Rises to the Challenge
April 2006

Orinda Grove Site Visit

A challenging new project, Orinda Grove, allowed WRECO to gain experience with the sophisticated C-3 storm water treatment requirements. Pulte Homes wished to construct a residential development in Orinda but the City was concerned about exacerbating potential flooding. WRECO provided hydrologic and hydraulic analysis, including examination of Storm Drain System Capacity, Storm Water Detention Requirements, and Storm Water Quality Treatment Requirements. WRECO's suggested treatment plans complied with C-3 regulations and offered a solution to Pulte Homes.

October 2005

Waldo Tunnel

WRECO is working with Caltrans to develop new drainage strategies for the Tunnel Wash Water NPDES. The wash water is accumulated from cleaning the Waldo Tunnel in Marin County, and Alameda County's Alameda - Webster and Posey Tubes. WRECO has developed alternatives to Caltrans usual technique of disposal, which is filling tanker trucks and hauling the wash water to East Bay Municipal Utility District's Treatment Plant. Alternatives proposed by WRECO include the direct discharge of wash water to the sanitary sewer systems or to a storage box for easy maintenance access. WRECO also is preparing Project Study Reports and cost estimates for the alternative options proposed to Caltrans.
