RYERSON UNIVERSITY DEPARTMENT OF CIVIL ENGINEERING FACULTY OF ENGINEERING , ARCHITECTURE AND SCIENCE NEW WINDSOR - DETROIT BORDER CROSSING STORMWATER MANAGEMENT SYSTEM B & H Consulting : MICHAEL BERGER FENNIE HO 2008
Introduction Windsor city is a key trade point between the United States and Canada . In 2001 alone , Detroit / Windsor merchandise trade totaled at over $140 billion After analysis , Canadian authorities have determined that Canadian / American trade is predicted to increase within the near future . As trade increases , current traffic flow will also increase . The current Border crossing facility does not not have the capacity to handle projected traffic . The current border crossing plaza is difficult to get to because it is linked up to the core city streets .
Background New border crossing will link up the with Canadian Highway system . Which will accommodate a greater traffic flow . New Border Crossing Plaza Will be designed in stages such that facilities are capable to accommodate projected traffic flow The Detroit River International Crossing Project is a large scale interdisciplinary engineering project currently valued at $1B

Rational Method
Q = C i A Where: Q = Peak Flow (m3 /s) A = Drainage Area (ha) i = Average rainfall intensity (mm/hr) C = Runoff coefficient (see Table 5 . 1 )

Time of Concentration
Tc = L / (3600 * V)
Tc = time of concentration (hrs) L = hydraulic flow length (ft) V = velocity (ft/s)
