1. Why is the plan being updated?

The city council adopted the first Master Drainage Plan in 2007, and several issues now drive the need to update the plan:

• Drainage facility ownership has changed and responsibilities need to be confirmed.
• New development and completed drainage projects will need to be incorporated.
• Improved detention pond maintenance policies are necessary to ensure detention ponds are properly designed, constructed, and maintained.

This plan will also identify drainage capital improvements projects necessary to address flooding concerns.

2. What is ISWMM?

ISMM stands for Integrated Storm Water Management Model, which is a tool that allows the city staff to evaluate drainage system performance for various scenarios (rain events). The City of Sugar Land’s Engineering Department uses ISWMM mainly for emergency preparedness and to identify potential problem areas to come up with potential drainage projects for inclusion in the Capital Improvements Program.
