1
Q

A basin (with or without a permanent pool) which is intended to TEMPORARILY HOLD surface runoff for the purpose of controlling both the DISCHARGE RATE and the RUNOFF VOLUME leaving the site or watershed. There is usually some min. storage component where the water can only leave the basin via infiltration or evaporation.

Q

Intersection Design Considerations

A

1) Distances bw intersections relates to street type and intended speed; impacts volume, speed, and porosity of street networks (more intersections = greater potential for conflict but increased connectivity)
2) Maintain clear line of sight at intersections
3) Crossing roadways should intersect at 90 degrees
