BACKGROUND INFORMATION:
The Dry Comal Creek is a major waterway through New Braunfels and a major source of flooding. It was last modeled and mapped in 2003 (in city limits) and 2005 (upstream of city limits). With projects, development and changes in hydrology in the watershed, the models and mapped floodplains are outdated. This hinders both development in the city as well as floodplain management because flood risk along the creek is uncertain. In addition, it is challenging to implement flood improvement projects along any of the tributaries to the creek because the tailwater effects of the Dry Comal Creek are unclear.
The purpose of this project is to update the FEMA effective floodplain mapping along Dry Comal Creek and a portion of Upper Dry Comal Creek, from the confluence of Dry Comal Creek and Guadalupe River to the Soil Conservation Service (SCS) Site Number 2 Reservoir:

A proposed expenditure of $200,000 would update the flood models and likely lead to floodplain map revisions. There is a chance (though not guaranteed) the study could formally document mitigated flood risk in and around the Dry Comal Creek, leading to lower insurance rates and an increase in developable property. The request originated out of the pre-development issues arising from the development of an office park adjacent to the existing floodplain maps of the Dry Comal Creek.
