IMHO, DES should worry about all those things, but here's what Science News wrote about runoff—excerpted:

"...On the green space that's left, even small amounts of traffic—tractors, golf carts, lawn movers, mere human footfalls—can compress the soil and reduce the rate at which it absorbs precipitation. As an environment becomes inhabited, therefore, less precipitation soaks into the ground, and runoff increases. As a result, floods occur more often and develop more rapidly.

The hydrological changes, along with the pollutants picked up by the water as it pours across the urban landscape can wreak havoc on aquatic ecosystems and damage habitats alongside waterways..."
