IH 35 at Lake Creek, Round Rock, Texas (2007).


HHR was on the design team for modifications to the IH 35 frontage road and existing ramp bridges.  We provided watershed hydrology and hydraulic analysis of existing and proposed structures.  Part of the design criteria was to show compliance with NFIP regulations.  We prepared updates to existing FEMA hydrology and hydraulics modeling and verified no impacts to floodplain/floodway elevations due to proposed construction.
