Stormwater Master Plan

How does a public authority who manages stormwater do it in an organized manner under high pressure and short time frame? Why don't we throw in a few extra challenges

1.  Large and, quickly intensified residential developments;
2.  Large medium to heavy industrial factories;
3.  Historically scattered management approach;
4.  Lenient or lack of Land Development Controls;
5.  Governance that does lacks capacity in organized planning;
6.  Large range of soils from coastal sands to shale and
7.  Other smaller easy to manage issues.

This is the best opportunity to do it right. It just needs a good understanding of the approach for High Level PLANNING, instead of a Detailed Plan.
