Drainage projects were identified by the criticality in nature per Drainage Master Plan criteria, from structural flooding to major thoroughfare ponding and to neighborhood street ponding as well as project readiness. City staff continues to coordinate emergency efforts during major storm events to improve pass-ability of roadways. The City has also purchased high-water vehicles that can provide rescues during major storm events. This effort is continually coordinated with the County, Levee Districts, Fire, Police, Public Works and Engineering. As we continue to go to the voters for approval of projects, other identified drainage improvements in various areas will be addressed in the next bond election.

Drainage problems have different tiers. The top priority for the city is to fix home flooding problems and the proposed drainage improvement projects will reduce the home flooding potential. We have also included drainage improvement projects that will reduce street ponding on major streets and in several neighborhoods.
The city continues to pursue Federal and state funds to supplement drainage projects. In order to construct the improvements as soon as possible, the City is seeking approval of bond authority which will allow the City to drive the schedule on these projects and not be dependent on other agencies to provide funding.
These projects will comply with ongoing Atlas 14 efforts. Sugar Land has adopted the Atlas 14 rainfall frequency estimates for Texas. This resulted in modifications to the city’s Development Code and Design Standards, and the city-adopted guidelines that provide guidance for the review of requests to alter or develop new property within the city. Changes resulting from the Atlas 14 adoption will apply to new development and redevelopment areas within the city and its extraterritorial jurisdiction (ETJ). The city is in the process of updating city-wide ponding maps using the new Atlas 14 rainfall information. The updated maps will show areas where potential street ponding might occur due to an increase in the frequency of intense rain events.
