The Route to Sustainable Development
In 1998, Bayport planning didn’t start with
―sustainability‖ in mind
Planning was molded by environmental and social
considerations
• Many planning commitments were codified by permits,
requiring special features and construction practices
―Green‖ development was an early focus
Design flowed from planning commitments
• Design details used best practices
• Sustainable design philosophy extended goals and further
improved the product

Bayport Sustainable Development
Focus areas:• Site factors
• Minimizing social impacts
• Storm water practices
• Emissions and air quality
• Energy efficiency
• Quality and durability of infrastructure
• Low-impact materials, reuse and recycling
• Other social and economic features
Full cycle considerations: planning, design, construction, and operations
![Page 11: Bayport and sustainable design · Design flowed from planning commitments • Design details used best practices • Sustainable design philosophy extended goals and further improved](https://reader034.vdocuments.mx/reader034/viewer/2022050514/5f9e24b5b0e07a36fd3b475e/html5/thumbnails/11.jpg)
Site Planning
Size considerations-right sizing
• Consolidation of container storage on the terminal—no sprawl
• Preferable to minimal site, with only core business
Transportation-help separate truck from POV traffic
Relocation of access roads to service communities
Insulate the terminal from the public-sight and sound
Minimize impact to municipal services
Best practices-stormwater management
During design, relocated the pre-check gate

Social Impacts-
Water and wastewater
Eliminated consideration of well supply, because of
association with localized subsidence;

connected it to municipal water line, to improve pressure
to the community—then conveyed it to the city
Constructed separate waste water utilities, tied to
industrial treatment facility

Sustainable Design Practice
Policy for PHA facilities
• Consideration of sustainable products and practices for all
terminal projects
• During development of every project, coordination among PM,
Environment, Operations, and Maintenance staff for sustainable
development and complementary improvements
• LEED standards for all major building projects
• Requirements and metrics part of the EMS
• Sustainable development outreach to tenants and Port of
Houston partners and businesses
PHA finds environmental, social, and economic
principles to be truly complementary
