This document discusses low impact development (LID) techniques for managing stormwater in the Houston region. It provides perspectives from design, construction, and agency professionals. The objectives of LID are to manage stormwater close to its source using natural processes, minimize impervious surfaces, and treat stormwater as a resource. Common LID tools discussed include bioswales, green roofs, cisterns, permeable pavement, and their applications in various local projects. Economics, maintenance considerations, and the Houston region's developing LID criteria are also covered.

This presentation will be a summary of what we know and where we stand eight months after Harvey at the beginning of hurricane season and what each of us can do going forward. The presentation will provide an overview of each of the bayous and stream and river systems including the issues that are particular to each of them as well as a discussion of the upcoming bond issue and a discussion of key upcoming issues.
Richard Vella, City of Houston
Peter McStravick, Houston First
Tom Smith and Hussein Moussa, ARUP
Houston’s history has included several storm events, including Allison, Ike, Rita and most recently Harvey. Harvey’s record breaking rains resulted in flooding that became an inevitable reality. Now, Houston has made the conscience decision to build back in a more resilient way, thereby minimizing damages in subsequent events. Recovery and restoration efforts were aided by the lessons learned during these previous events. This panel session will feature representatives from City of Houston and Houston First describing how they rebuilt and restored their building operations following the Harvey storm. Those discussions will be expanded to highlight some of the key design and planning considerations that will be adopted moving ahead with this work.

This session will take a look at the multi-faceted design approach to education carried out by the newest UHD campus addition. The University of Houston Downtown Sciences and Technology building not only provides an opportunity of formal education, but the design of the building also lends itself to an educational experience for both students and faculty alike.
Throughout the project, educational and sustainable moments are showcased within the design, allowing the program to practice what it teaches. The site is designed to react to the flood plain by the use of paving quantities and site location, and a resilient landscape is achieved through the use of native plants as well as a water filtration system that is made of existing recycled concrete. Through the project, water flow can be traced from the building, through the site and ultimately into the bayou. The school’s program ties into the design by using native plants as learning opportunities as well as educational graphics that are located throughout the project. As a downtown campus, the building is connected to the existing hike and bike trail adjacent to the bayou, as well as the downtown urban edge along Main Street. This location enhances pedestrian activity through the project’s site and increases health and wellness.
Preparing for a Black Swan: Planning and Programming for Risk Mitigation in E...juliekannai
Scott Tucker and Verrick Walker, Page
A Black Swan is an event that appears random, is extremely difficult to predict, and usually occurs unexpectedly—with a huge impact. The flooding from Hurricane Harvey in 2017 was Houston’s Black Swan. Unfortunately, we seldom think of disastrous flooding in our commercial buildings, bioterrorism in our health care facilities, blasts in our mission critical facilities, or wildfires overcoming our civic infrastructure, until another black swan dominates the news.
Over the past two decades, Page has formally helped owners and operators of critical facilities and infrastructure to plan and organize programs to harden and protect assets from a wide range of common and not-so-common threats, both natural and artificial. Beginning in 2001, we implemented a flood mitigation solution for Baylor College of Medicine’s campus in the Texas Medical Center after Tropical Storm Allison. Since that first project, we have helped academic, corporate, and government clients safeguard their facilities against fires, hurricanes, earthquakes, explosions, terrorist attacks, and even nuclear detonations. Through our work, we have developed a useful analytical framework for exploring resilient design options that applies to all types of threats, responses, and recovery efforts. This approach focuses on planning and programming for system-wide robustness, based on generalizing threats to buildings, rather than using actuarial data or calculated risk analysis.
This presentation outlines a practical methodology for architects to evaluate facility vulnerabilities throughout the programming and design phases. We will share our threat matrix, a tool developed to summarize and prioritize risks, case studies of how we have implemented this process, and the resulting robust solutions. We also will discuss operational steps that can be taken before, during, and after extreme events in conjunction with designed solutions to maximize resilience.
Alex Westhoff, Marin County Department of Public Works
Role-playing time! Marin County’s "Game of Floods" is a fun, engaging activity to help officials and citizens confront the complexities and challenges of adapting to Sea Level Rise. The simulated, fictitious island game board addresses nature-based protections, building retrofits, land use policy changes, and traditional engineering to solve for future sea level rise. Marin County developed the Game because an educated citizenry is critical to successful planning and implementation.
This small group activity involves 4-6 participants tasked with developing a vision for the hypothetical island landscape that highlights conditions that will be experienced in coming years with sea level rise and increased storm impacts causing the loss or deterioration of homes, community facilities, roads, beaches, wetlands, and other resources.
Jaime Gonzales, the Nature Conservancy, and Beth Clark, Clark Condon Landscape Architects
The Coastal Prairie Partnership, Katy Prairie Conservancy, Houston Native Prairie Association of Texas, and Clark Condon Associates came together to introduce a simple palette of native plants that is commercially available for the community to use in their landscapes. The Nine Natives were selected to work together to give a beautiful show in the garden throughout the year. Species were selected for their extended or repeat blooms, interesting foliage, contrasting colors and textures. All were chosen for the benefit to butterflies, hummingbirds, birds, beneficial insects and other wildlife in the garden and ethnobotanical value. The program includes example plans for formal and informal home gardens and street median plantings and a plan to demonstrate a multi-speciesplanting to create a native pocket prairie.
While some species are strong enough in monoculture, others may be more effective in mixed groupings. The Nine Natives were judged to be a collection that would be appealing to local gardeners - easy to grow - and with a height and habit acceptable to the residential garden or street median. Most of the species are available through local specialty growers, if not local nurseries. The collection is a mix of grasses and forbs, perennials, or re-seeding annuals. Some flowers may give a quick show of brilliant color and others may carry the show throughout spring into the summer and fall long enough to contrast with the soft bloom and foliage of the native grasses in the palette. These Nine Native species may be used to incorporate natives in lieu of, or in addition to, horticultural (non-native) species. Used individually, planted in landscape beds in groups, or mixed together to make a prairie - no matter how they are used - these Nine Natives will add to the beauty and enjoyment of our gardens and neighborhoods.

Economic Resilience in the Houston Galveston Regionjuliekannai
Joshua Owens, Houston-Galveston Area Council
Economic resilience is the ability to prevent and withstand disruptions to the economy. The most common types of disruptions include downturns in economy or in a key industry; the closure or exit of a major employer; and natural or manmade disasters. Creating a resilient economy requires the ability to anticipate risk, evaluate how risk can impact economic assets, and building the capacity respond to disruptions. The Houston-Galveston region has one of the most robust economies in the nation with major economic assets including the energy, agriculture and medical industries; international ports; and new plant expansions. The region is also vulnerable to wide range of natural hazards, including flooding, tornadoes, tropical storms and hurricanes; as well as potential manmade threats such as chemical releases. Local economies throughout the region can be impacted by a downturn in major industries or the loss of important employers. By identifying potential economic disruptions in the region, and conceptualizing economic resilience, creates the means to enhance the region’s economic resilience, through developing a vision for resilient regional economy.
Communicating Flood Risk Using Esri Story Mapsjuliekannai
Bradley Dean, Coastal Scientist, Michael Baker International
Communicating about flood risk and hazard mitigation is challenging and requires storytelling. Our brains are wired to discount facts and the future. During this session, Coastal Scientist Bradley Dean CFM, CE, will explore three use cases for story maps focusing on best practices for communicating flood risk and mitigation initiatives:
• Annapolis, Maryland needed a platform where residents and stakeholders could visualize and interpret the city’s flood mitigation efforts.
• FEMA’s Cooperating Technical Partners’ Recognition Program wanted to showcase award recipients, San Antonio River Authority and Illinois State Water Survey, for their outstanding efforts in a unique way.
• FEMA’s Risk MAP Program needed to increase awareness of non-regulatory flood risk products and their associated benefits for a broader audience.
The solution was to develop story maps which utilize maps, narrative text, and multimedia content to increase accessibility and engage their target audiences. The applications are designed to be attractive and usable by anyone, which makes them great for education and outreach, either to the general public or to a specific audience.
Story maps are an excellent resource to increase local awareness of current and future flood risk and interpret, prioritize, integrate, and implement solutions that reduce risk to enhance community resilience.
Promoting Resilient Communities with the SITES Rating Systemjuliekannai
Danielle Pieranunzi, SITES Program Specialist, GBCI
Too often, landscapes are seen as an afterthought – something to be altered and shaped once elements like buildings and roads are finalized. Modeled originally after LEED, the SITES program has shifted the focus beyond the building to reveal the necessity of healthy, functioning landscapes and green infrastructure in achieving overall sustainability and community resilience. High-performance sites provide a variety of benefits and can create ecologically resilient places better able to withstand and recover from catastrophic events. This session will frame the importance of land design and development by exploring the SITES v2 Rating System and relevant case studies.
Post Harvey Flood Data and the Future of Resilient Infrastructurejuliekannai
John Blount, Harris County Engineer
In late August, a downgraded tropical storm Harvey, which made landfall as a category 4 hurricane just days before, stalled over southwest Texas causing torrential flooding throughout the region. Unincorporated Harris County alone was inundated with in excess of a trillions gallons of storm water over 4 days, enough to fill the Astrodome 3200 times. In the aftermath of the unprecedented event, local officials were left to shepherd constituents through recovery and back to a sense of normalcy.
In this presentation, the county engineer, John Blount, gives a detailed account of the after events of Hurricane Harvey and its effects on the environment, infrastructure and community. Mr. Blount will analyze flood data yet to be released to the public, in order give the audience a perspective of just how devastating Harvey’s flood waters were. This session will breaks down the county facilities destroyed by Hurricane Harvey and John’s vision to respond with resilient solutions instead of temporary fixes because with the frequency and severity of recent storms, this could be the new normal.

Book Formatting: Quality Control Checks for DesignersConfidence Ago
This presentation was made to help designers who work in publishing houses or format books for printing ensure quality.
Quality control is vital to every industry. This is why every department in a company need create a method they use in ensuring quality. This, perhaps, will not only improve the quality of products and bring errors to the barest minimum, but take it to a near perfect finish.
It is beyond a moot point that a good book will somewhat be judged by its cover, but the content of the book remains king. No matter how beautiful the cover, if the quality of writing or presentation is off, that will be a reason for readers not to come back to the book or recommend it.
So, this presentation points designers to some important things that may be missed by an editor that they could eventually discover and call the attention of the editor.

3. LID-low impact development – what is it?
LID is an approach to land development that works with nature to
manage stormwater as close to its source as possible.
LID employs principles such as preserving and recreating natural
landscape features, minimizing imperviousness to create functional
and appealing site drainage that treats stormwater as a resource rather
than a waste product.
There are many practices that have been used to adhere to these Westpark Tollway
principles such as bioretention facilities (bioswales), vegetated swales,
rain gardens, vegetated rooftops (greenroofs), rain barrels, tanks and
cisterns, and permeable pavements.
LID Works Everywhere
LID can be applied to new development, redevelopment, or as retrofits
to existing development. LID has been adapted to a range of land uses
from high density ultra-urban settings to low density development.
LID and Green Infrastructure
Citation Campus
EPA intends the term "green infrastructure" to generally refer to
systems and practices that use or mimic natural processes to infiltrate,
evapotranspirate or reuse stormwater or runoff on the site where it is
generated.
