Green Infrastructure

NCTCOG promotes the planning and construction of green or sustainable infrastructure in the region to help reduce carbon emissions, mitigate urban heat islands, reduce pollution from stormwater runoff, and provide health benefits to communities. Types of green infrastructure include LED and solar lighting, permeable pavement, “cool” pavement, bio-retention drainage areas, parks, community gardens, and shade trees.

Blue-Green-Grey Funding Program

Blue-Green-Grey Funding Program

The Blue-Green-Grey funding program focuses on breaking the silos between water infrastructure, the environment, and transportation infrastructure to help create and fund innovative spaces and solutions that combine these components. The goal of the Blue-Green-Grey program is to support innovative pilot projects that provide resources for cities and organizations to use to replicate these ideas throughout the metroplex. 

2024 Funding Opportunity

The Blue-Green-Grey Application for New Ideas is now open!
Deadline: Hard copy applications and electronic version on USB are due in hand by 5:00 pm CT on August 16, 2024. Deliver to the NCTCOG offices at 616 Six Flags Dr., Centerpoint Two,  Arlington TX 76011

Program Rules and Considerations

  • Projects or programs must be located on public land or in the public right-of-way within the 12-county Metropolitan Planning Area
  • Funding is reimbursement only
  • Typically, about six months is required after the award before funds may be accessed, to allow for processing and contract development
  • Work started before a project contract is executed is not eligible for reimbursement
  • NCTCOG reserves the right to remove funding on work that is completed prior to contract execution
  • Any procurement that occurs after project award must comply with NCTCOG and State procurement requirements

Please contact Shawn Conrad with questions. 


Blue-Green-Grey Environmental Panel

NCTCOG hosted a Blue-Green-Grey Environmental Panel on April 14, 2021 to gather feedback from stakeholders about the previously implemented funding program and awarded projects. This feedback will be presented to NCTCOG boards and used to develop a fourth call for projects in the coming months.

Previously Funded Projects

Funding Year 2021

City of Allen Inlet Floatables Filter ProjectCity of Allen Project Cover
The purpose of this project was to design a non-proprietary Inlet Floatables Filter to improve stormwater quality and first flush debris entering the stormwater system and then discharged into creeks. The goal was to design a permanent filtration system, not impacting hydraulic capacity, to meet the Texas Commission on Environmental Quality's stormwater permitting requirements.

UTA Testing of Engineered Media for Biofiltration Swales 
The purpose of this project was to investigate alternative methods to remove total suspended solids from run-off.  In this project, a comprehensive laboratory investigation centered on using the expanded shale as a filter reduction in bioswales. While conventional filter media, including rocks, sand, and mulch, have been employed in bioswales to bolster infiltration capabilities, the potential of engineered expanded shale as an alternative medium remains relatively unexplored and under-documented.


Bottom District Neighborhood Beautification and Green Infrastructure 
The project will establish a green infrastructure pilot project in a historically underserved neighborhood located in a FEMA floodplain, where neighborhood revitalization and home building are a challenge. The project aims to increase community beautification opportunities, sustainably manage flood risk, and provide opportunities for the neighborhood to thrive.  Completion is anticipated in 2025.

Funding Year 2018

DART Hatcher Station Community GardenBGG Book Cover
BGG funds were used for the development and implementation of a community garden located in an unused parcel in DART-owned right-of-way near Hatcher Station. The pilot project acted as a programmatic approach to create community gardens for areas designated as “food deserts”. 



Bishop Arts Bicycle Parking Retrofitting Project
The Bicycle Parking Parklet Retrofitting Project took place in the Bishop Arts neighborhood in Dallas. Funds were used for the development and implementation of an eco-friendly bike parking and public seating parklet in the Bishop Arts District in Dallas. The pilot project established a replicable green parklet design, suitable for mixed use and neighborhood walkable retail districts.

City of Watauga Hightower Rain Garden ProjectHightower Rain Garden Project Cover
Summary: This project features the installation of a new rain garden on a storm drain inlet on Hightower Drive in Watauga. The intent of the project was to redirect storm water runoff to the rain garden to filter pollutants
prior to entry into the stormwater system. The project report includes a rain garden design that can be scaled to many areas. 


Funding Year 2017

Green Bus Stop Design Guide - City of Farmers Branch
This guide was developed by the City of Farmers Branch to develop a process and tools for implementing green bus stops as part of standard development processes. This guide highlights the City’s overall purpose and approach to a green infrastructure project, and includes general information on project site selection, bus stop design templates, and a planning/design checklist that can be used by other agencies and municipalities for developing green bus stops.


Southlake BioPod Burney Lane Reconstruction
The City of Southlake purchased and installed a prefabricated BioPod biofiltration system as a test pilot project. The system includes water testing and monitoring to ensure its success. The City has created an internal dashboard to reflect all trends recorded since the project began.

University Park Micro-Detention Project  
This project consisted of the design of a new micro-detention system for driveways. The project included a CAD design that will be used by the City of University Park in a future pilot at one of their facilities.

Green Infrastructure Resource Guide

NCTCOG completed a guidebook in 2017 to aid professionals in assessing choices for integrating green infrastructure practices into various transportation projects such as roadways, sidewalks, parking facilities, and trail projects. The guidebook provides costs and benefits of these green practices, local case studies, and key information related to long-term cost effectiveness, community improvement, and environmental impacts.  The following topics are covered in the Guidebook:

  • Energy-efficient LED and solar lighting
  • Green stormwater infrastructure elements such as permeable pavement and bio-retention
  • Green trail materials and “cool” pavements
  • Urban forestry and native plants
  • Local examples
  • Cost estimates

Local Examples

NCTCOG has funded a number of infrastructure projects through the Sustainable Development Funding Program that utilize green infrastructure components or strategies.

Below are some examples:

The Green at College Park – Arlington College Town, Arlington, Texas
Walking pathLocation:  Public open space adjacent to the University of Texas at Arlington Lipscomb Hall, fronting Third Street, Center Street, and Mitchell Street.
Green Infrastructure Elements: Pedestrian walkway paved with pervious recycled glass material; bioretention drainage garden; and shade and paving materials with a Solar Reflection Index (SRI)
value of 29 or greater to reduce the heat island effect.
