The innovative Cross Border Xpress (CBX Terminal) is renown for its 390 foot long skywalk bridge for airline passengers crossing between San Diego and Tijuana Airport. As part of this new International Cross Border Facility, the developer was responsible for widening over a mile of existing public roads to accommodate anticipated traffic volumes. The road work presented design challenges, particularly as the first street widening project within San Diego subject to new MS4 Storm water regulations for hydromodification.

While Fuscoe had designed and permitted several projects subject to the new regulations, this project was unique. The Fuscoe team had to develop a system that did not require additional right-of-way acquisition and satisfied all City departments. The solution: three separate “treatment train” systems that addressed various storm water requirements. The first system utilized a hydrodynamic separator with media filter combined with a regional detention facility for hydromodification flow control. The second used the same initial treatment method in conjunction with a 48” RCP storm drain system within the public road for hydromodification. The third also utilized the same initial treatment scheme, but with a highly modified flow through planter, one of the more challenging solutions that were ultimately granted City approval.
