3. LEARNING OBJECTIVES
At the end of this program, participants will be able to:
1.Understand regional risks associated with severe
weather events.
2.Recognize opportunities for economic, recreational and
infrastructure development in at risk areas.
3.Be able to establish site selection and design criteria
for sustainable, resilient coastal development.
4. COURSE DESCRIPTION
The Houston-Galveston region is uniquely susceptible to the risk of
hurricane related tidal surge and rainwater flooding. Repeated
hurricanes and tropical storms have devastated this part of the Gulf
Coast and yet a substantial portion of the region's diverse and rapidly
growing population is living inside potential tidal surge inundation
areas. The vast industrial infrastructure of the Houston Ship Channel,
the largest collection of refining and petrochemical storage facilities
and infrastructure in the nation is also at risk of catastrophic flooding.
Based on analyses undertaken by the SSPEED Center, this
presentation will describe the specific risks faced by individual districts
and local communities and proposals for a layered system of coastal
protection. These proposals include structural and non-structural
alternatives.

164. WHAT IS A NATIONAL RECREATION AREA?
Federally Recognized Recreation Venue Created by
Congressional Action.
Can Be Established and Operated Under Innovative
Partnership Agreements (Charter) Between Local, State and
Federal Governments and Non-Profit Organization and
Private Property Owners.
No Additional Regulatory Burden For Non-Participating
Parties.
No Unwilling Participation.
165. GOVERNANCE BY PARTNERSHIP
National Recreation Areas:
Can be managed though partnerships among local,
state, and federal government agencies, nonprofit
organizations, and private landowners.
Provide a flexible way to gain the stature of National
Park Service involvement, while sustaining local
management.

17.8 million Americans ages 6 and older participated in
kayaking, canoeing, and rafting in 2008.
9.9 million Americans participated in canoeing in 2008.
7.8 million Americans participated in kayaking
Paddling participants made 174 million outings in
2008, averaging 10 days per participant.
The SSPEED Center (taken from the brochure): In the aftermath of Hurricanes Katrina and Rita it was obvious that there needed to be a technical discussion about the all encompassing power and damage that hurricanes can cause along the Gulf Coast. The Severe Storm Prediction, Education and Evacuation from Disasters (SSPEED) Center was established in 2007 as a university based research and education organization. Led by Rice University, the SSPEED Center organizes leading universities, researchers, emergency managers, and private and public entities to advance research that supports the creation and dissemination of knowledge to better address severe storms and their impact on the Gulf Coast.
Example #1 of Hurricane Modeling Abilities at the University of Texas ADCIRC modeling allows researchers to identify vulnerable areas along the coast. Modelers can reproduce real storms as well as developing hypothetical storms to examine their impacts. SEE NEXT SLIDE ADCIRC Modeling Capabilities (taken from the brochure): Ike is the most destructive hurricane to make landfall on the Texas coast since the Galveston Hurricane of 1900 and serves as the basis for much of the research conducted by the SSPEED Center. ADCIRC modelers at the UT Space Science Research Center in Austin have completed a series of model runs that show the impacts of modified versions of Hurricane Ike (i.e. higher wind speeds). Their results allow us to inspect the relative benefits of implementing a series of structural and non-structural mitigation techniques to protect coastal areas. The research completed by the SSPEED Center to address hurricane vulnerability will set a national example for coastal protection strategies in terms of economy, social structure, and environmental policy.
Example #2 Hurricane Modeling Abilities at the University of Texas: Modified Hurricane Ike Hurricane Ike had it made landfall near San Luis Pass As shown, flooding could have been much worse, had the storm made landfall 30-50 miles further south. Later in the presentation we will also examine the impacts of a Category 3 storm (Hurricane Ike + 15%) making landfall near San Luis Pass. The importance of such modeling to the SSPEED Center also allows us to examine the impacts of proposed protection strategies such as levee systems and flood gates… SEE NEXT SLIDE
Galveston Bay's funneling geometry places the communities of West Bay in harm's way; 244,500 people and 81,500 jobs exist within the 25' contour.
Planning team publications have evaluated the 'vital statistics' of successful coastal parks. The Galveston Bay area is a prime candidate for a significant coastal park. Investigations include: 28 park case studies, urban access to regional parks, precedent parks sizes and shape, and park proximity and economic impact.
There is a two-fold benefit to a National Recreation Area in Galveston Bay: it will provide the Houston-Galveston region from storm surge in addition bolstering the state’s limited park network.
