The time of concentration (Tc) refers to the amount of time it takes for water to travel from the most distant point in the watershed to the outlet. By retaining predevelopment Tc, negative impacts associated with development can be reduced. Maintaining Tc can be achieved in a development by which of the following?a.Decreasing flow path lengthsb.Decrease surface roughness c.Disconnect impervious surfaces d.Disconnect pervious surfacesNew York State Stormwater Management Design Manual http://www.dec.ny.gov/chemical/29072.html
