Letter to the editor: Our city plans to allow major commercial development along the south waterfront and, in so doing, to increase its tax revenue. But, to succeed commercially, the development would inevitably create far more road traffic than the existing roads to the waterfront can handle, causing serious traffic congestion. Providing enough roads or public transportation to the area would cost far more than the city could gain from the increased tax revenue.

Which of the following, if added to the city's plan, would be most likely to help solve the problem the letter describes?

(A) Funding construction of new roads to the waterfront with a system of tolls on the new roads to the waterfront

(B) Allowing residential development along the waterfront so that there will be waterfront residents who can walk to the commercial development

(C) giving tax breaks to developers of businesses along the waterfront to offset any tax levied on them for construction of roads or public recreation

(D) Evaluating the net benefits that the commercial development would bring to the city in terms of improved quality of life for the city's residents rather than its financial terms

(E) Allowing commercial development in other city neighborhoods whose roads are not seriously congested with traffic
