6 History of Flooding and Severe Weather (2001-Present) TS Allison (June 2001) Hurricane Ike (September 2008) Rain Events of January 9 th and April 27 th 2012 TS Bill (June 2015) Memorial Day (2015) Tax Day (2016) October (2016) January 18 (2017)

7 Overview of the Area

8 Needs for Inland Flood Protec_on Rapidly moving weather systems explosive rainfalls Urban developments exceeded the original design capacity of the channels Severe street flooding occurs during rou_ne rainfalls Damage costs con_nue to increase Timely informa_on for flooding and evacua_ons

9 What does FAS do? Increase lead _me for flood warning Provide accurate real-_me radar rainfall es_mates Radar rainfall can be visualized over the watershed in Google Maps Provide frequent informa_on updates via the web site Provide communica_on emergency response and opera_ons

10 GIS and Radar Rainfall Revolu_onized Hydrology Watershed analysis within GIS Satellites & sensors providing meteorological data NEXRAD and CASA NetRAD radar systems LiDAR advanced topography and DEM Advanced hydrologic/hydraulic modeling systems

11 FAS operates with Real-Time Radar Data Radar data reflects off raindrops and is processed and calibrated every 5 min. Radar rainfall data is delivered to Rice for 43 sub-basins over Brays in 5 min. intervals Data is inserted into a hydrologic predic_on model, HEC-1, to predict peak flows for TMC within Brays Bayou Bayou cameras provide vital water levels as storms progress and are delivered to FAS

25 Flood Protec_on UT Health Ini_al Flood protec_on is provided by a berm that consists of flood gates, concrete stairs, concrete walls, road humps, buildings and earthen landscaping The perimeter berm provides protec_on 1 foot above the 100 year flood plain level (45') with the top of the Medical School loading dock at 47 Six sump pits have been installed around the Medical School to handle rainfall within the berm's perimeter

26 Flood Protec_on UT Health There are 23 flood doors that make up the Medical School perimeter Each flood door is designed so that it may be closed by only one person in under 5 minutes Closure sequence of the flood doors is based on a risk assessment with flood doors in the lowest lying areas shut first The Medical School building is also protected by a hydrosta_c wall and aquarium glass

39 Current Flood Gate Deployment Plan Flood Gates Deployment Plan

Current Decision Matrix When Box Culvert reaches 5 q. TMC ini_ates a Flood Advisory message When Box Culvert reaches 7 q. TMC ini_ates a Flood Alert message At 9 q.

40 Current Decision Matrix When Box Culvert reaches 5 q. TMC ini_ates a Flood Advisory message When Box Culvert reaches 7 q. TMC ini_ates a Flood Alert message At 9 q. MDA ini_ates a Level 1 severity level At 12 q. MDA ini_ates a Level 2 and begins raising Level 2 Flood Gates At 15 q. MDA ini_ates a Level 3 and begins raising Level 3 Flood Gates Decision to raise Level 4 gates are not based on culvert/bayou height only its ability to maintain rou_ne pa_ent care requirements

41 Current Decision Matrix Rainfall es_mates and predicted peak flow rates will assist in determining the Alert/Warning level Predicted peak flow will coincide with a predicted Box Culvert height Established culvert heights will trigger MD Anderson s Flood Plan and its preparatory ac_ons

42 Re-evalua_on of flood gate deployment Improved capacity of the bayou Improved drainage from the TMC 12-q increase in water entering the bayou and safely draining out Past storms: TS Allison (June 2001): 27,000 cfs (TMC flooded) Hurricane Ike (Sept 2008): 26,811 cfs (TMC flooded) January 9, 2012: 25,300 cfs Memorial Day 2015 Flood: approx. 29,000 cfs Tax Day 2016: approx. 28,000 cfs January 18, 2017: approx. 25,000 cfs

43 New Decision Matrix Box Culvert reaches 15 q. or projected rainfall accumula_on aligns with TMC s medium level of concern: Update provided to ac_vated ICS staff Recommenda_on to begin raising Level 2 flood gates (*re-designated as Flood Stage Orange to coincide with Flood Alert System)

44 New Decision Matrix Box Culvert is projected to surpass 18 q., predicted peak flow rate exceeds 24,000 cfs. and/or projected rainfall accumula_on aligns with TMC s high level of concern: Update provided to ac_vated ICS staff Recommenda_on to begin raising Level 3 flood gates (*re-designated as Flood Stage Red to coincide with Flood Alert System)

45 New Decision Matrix If predicted peak flow rate exceeds 30,000 cfs., the Bayou has crested the top of the bank and/or projected rainfall accumula_on aligns with TMC s hundred-year level of concern: Update provided to ac_vated ICS staff Recommenda_on to begin raising Level 4 flood gates (*re-designated as Flood Stage Purple )

46 New Deployment Plan

47 January 9 th 2012 Event TMC, Brays Bayou and Harris Gully, which run through the Texas Medical Center, received over 5 inches of rain, including 4-1/2 inches in 4 hours, causing the closure of Highway 288 at Holly Hall from late morning to mid aqernoon

48 January 9 th 2012 Event

49 January 9 th 2012 Event

50 January 9 th 2012 Event At its peak, Brays Bayou was channeling more than 25,300 cubic feet of water per second, or 84% of the full capacity peak flow of 30,000 cubic feet of water per second. The TMC, however, did not experience flooding during this storm due to many FEMA funded flood protec_on projects implemented in and around the Texas Medical Center.

51 Project Brays The $489 million project includes widening 21 miles of Brays Bayou, excavating four massive detention basins that collectively store several billion gallons of storm water, and replacing or modifying 32 bridges
