The purpose of this presentation is provide a introduction to and discussion on green highways. At the end of this presentation, you will be able to: Describe greener approaches to planning, design, and construction Discuss funding opportunities and sources Cite national case studies Explain federal, state, & local perspectives Purpose and Learning Objectives
“The Green Highways Partnership (GHP) watershed approach… Recognizes that multiple land uses coexist in watersheds Uses a collaborative approach – Provides an opportunity for organizations to plan and deliver the most cost-effective protection, even improvement, to watersheds Goes beyond NPDES compliance – Shifts perspective from implementing stormwater exclusively on-site that meets conventional regulatory guidelines to off-site that addresses watershed improvement goals This framework can serve as a model for other departments of transportation.” Raja Veeramachaneni Co-Chair, GHP Watershed-Driven Stormwater Management Team
Presentation Introduction to the Green Highways Partnership (GHP) Greener Approaches to Planning, Design and Construction Funding Opportunities and Sources Making the funding connections, such as ARRA National Case Studies Federal, State & Local Perspectives Facilitated Discussion & Question and Answer
GHP o Purpose o Background o Highlights Green Highways Watershed Approach to Stormwater Management o Linear projects at the state and local DOT level o Principles & Regulatory Connections
Formed in 2005 Voluntary – Not Regulatory Collaborative Effort Public-Private Partnership Goals – Promote innovation, stewardship, streamlining, and green solutions for the linear transportation projects Green Highways Partnership (GHP)
Green Highways & Green Streets enable: o Development of integrated watershed planning approaches o Leveraging of resources (technology, funding, outreach o Integration of green elements into infrastructure o Creation of partnerships and development of cross-cutting programs o Creation of Context Sensitive Solutions
GHP Framework: 3 Major Environmental “Theme” Teams – Conservation & Ecosystem Protection – Recyclables & Reuse – Watershed-Driven Stormwater Management Ten Guiding Principles!
Theme Teams Conservation & Ecosystem Protection Establish regional ecosystem frameworks and an ecosystem approach to transportation programs and projects. Recyclables and Reuse Promote environmentally sound use of industrial, residential, and commercial materials and byproducts Promote practices that conserve non-renewable resources, reduce impacts to landfills, reduce greenhouse gas emissions, and save energy. Watershed-Driven Stormwater Management Implement watershed-driven approach to address stormwater impacts through integrated and innovative practices
Uses natural infrastructure approaches to link transportation and environmental planning. Identifies critical habitats and other areas of ecological importance Facilitates the placement, design, and scope of future transportation projects Urban Ecosystem Analysis can accurately measure “environmental savings* of using a “natural infrastructure approach”. *Potential savings that can be calculated are: Non-point source stormwater impacts Carbon sequestration and storage Conservation & Ecosystem Protection

NCHRP Project Evaluation Methodology Material Screening Detailed Laboratory Evaluation Fate and Transport Modeling Evaluation of Data and Characterization Potential Impacts Report with Tools/Methodology for Evaluating materials is available Main components of C&R material evaluation:
NCHRP Project Waste and By-product Materials Evaluated
Environmental o Avoided impacts from processing virgin materials (e.g. GHG emissions) Economic o Reduced transfer and disposal costs Performance o Perform as well as or better than traditional materials Increased strength, improved workability, resistance to chemical attack, longer life Recycling and Reuse (R/R) Benefits of Industrial Materials Use
State DOT pilot projects that optimize beneficial use of byproducts o Virginia, West Virginia, Maryland, and Pennsylvania Efforts currently include: o Virginia GHP demonstration projects and Green Rating System o Mid-Atlantic Specification Harmonization Task o Information exchanges (NRC, other regions), outreach tools Recycling and Reuse (R/R) Examples
Watershed-Driven Stormwater Management Promotes coordination of public and private stakeholder interests toward watershed protection Supports & integrates R&D – leveraged to address data needs and gaps Uses collaborative partnerships to produce tangible results Provides an opportunity for infrastructure agencies to plan and deliver the most cost-effective protection that includes added benefits to watersheds Promotes protection and restoration measures both inside & outside the DOT ROW
Watershed-Driven Stormwater Management Principles of Watershed Approach Regulatory compliance is the minimum Requires a stormwater management plan considering watershed-wide needs – Targeted results per year Focuses on achieving overall positive environmental results for the watershed Integrates stormwater plans into transportation project development and project features
Watershed-Driven Stormwater Management Highlights GHP Model DOT Stormwater Permit R&D project – Use of Slag to Reduce P Loadings County Partnering – Green Highways & Green Streets Villanova Porous Pavement Study Maryland State Highway Watershed Approach Support for Anacostia Watershed-Driven Nannie Helen Burroughs (NHB) Project Support for Prince George’s County, MD Watershed BMP Optimization Model Support for GI-Driven Training – including this Webinar
GHP Watershed-Driven Stormwater Pilot: Development of a DOT Linear-Based Model NPDES Stormwater Permit Using Green Infrastructure Strategies – Partners: EPA Region 3, DNREC, DelDOT, FHWA Purpose – Develop a model watershed-driven stormwater permit that utilizes greener stormwater management controls and cost/effective O&M for DOT facilities and operations. Why? – Supports GHP objective to collaboratively develop and evaluate innovative solutions that achieve “better than before” results - tailored for the linear transportation environment.
GHP Design Principles Watershed serves as a driver for Context Sensitive Design DelDot MS4 Permit Prototype used Already utilizing green “infiltration” practices due to DE Green Technology Standards Evaluate streamlining & general permit opportunities Provides foundation for “credit” system GHP Design Toolbox Mix of traditional & non-traditional (LID) practices within & outside of the ROW GHP Watershed-Driven Stormwater Pilot: Development of a DOT Linear-Based Model NPDES Stormwater Permit
