That's a lot of property for the detention pond etc. How much do we expect this will relieve flooding in the area, including the fire station? Generally speaking.

Response provided by Rey Garcia, Senior Engineer:

The latest option includes channel improvements behind Grande, a storm sewer addition behind Grifols and adjacent to the Telluride Apartments all that drain into a proposed detention pond next to and behind Hilton Garden Inn. Localized inundation depths are reduced in these areas as well as the surrounding area by improved conveyance through storm sewer and channel improvements. Intuitively, increased pond volume will help localized flooding across the IH-35 frontage road as well as provide more storage capacity for the new storm sewer draining into the pond. More specific information is currently being developed through additional flood modeling that incorporates the increased pond size.
