EJ League of Rhode Island, Urban Ponds and Stormwater

Summary: Urban ponds and stormwater, environmental justice, pollution in local pond, greening neighborhoods, managing stormwater in urban areas to handle pollution, heat islands, recreational opportunity access, green spaces

The EJ League, Urban Pond Procession, and Groundwork Providence are working together on a new campaign to address stormwater pollution in Mashapaug Pond, Providence’s only remaining natural pond, located in South Providence.
See below for all the great successes we’ve already had in Reservoir Triangle around the pond! Addressing stormwater pollution has a ton of positive impacts you might not even be aware of — things like:
beautifying and adding green space to urban neighborhoods
improving air quality with more trees and plants
reducing flooding on our streets
creating jobs and training opportunities for Providence residents
helping our neighborhoods be more resilient in the face of climate change impacts like heat waves, storms, and major flooding events
improving the quality of Rhode Island’s water bodies and beaches — from our urban ponds and rivers to Narraganset Bay — they’re all connected!
Solving our stormwater problem is central to achieving environmental justice in Providence and Rhode Island’s other urban centers. Our urban communities have higher poverty and unemployment rates, its where the majority of people of color in the state live, and these are the same places with poorer air and water quality and less access to good things like green space, recreational opportunities, and the beauty of the natural environment. Cleaner water means more recreational opportunities like fishing and boating can happen right in our cities and we’ll be safer when we go to beaches on the coast. Protecting our waterways, adding more green space, and improving the public spaces we already have means we’ll benefit by being more connected to the natural environment too. Investing in
green infrastructure
means more jobs can be created for residents in Providence and other cities to install and maintain rain gardens and permeable pavement, de-pave driveways and right-of-ways, cut curbs and plant trees.
Check out our resident handbook on stormwater and green infrastructure
below, created specifically for Reservoir Triangle, but can definitely be used for other neighborhoods across the state!

September 15th, 2012 – Kick-Off – Mashapaug Pond Party:
We want to make sure people see Mashapaug Pond as a
real asset and natural resource in our city
. Duck Truck Tours are a good first step! We took about 75 people out on the water at our kick-off event in September and had a great time with food, music, and games for kids.

October 20th, 2012 – Stormwater Walk
led by George Harvey, Landscape Designer and project partner from
Groundwork Providence
: 20 people from the neighborhood and allies from partner organizations participated in a walk around Mashapaug Pond, focusing mostly on JT Owens ballfield and the Huntington Industrial Park.
George talked with us about various ways stormwater could be better managed to prevent runoff from the fields and businesses
there including:
raising grated storm drains located near baseball fields to slow down water rushing into pond
planting native plants to prevent soil erosion and slow water down, help it be absorbed
identifying specific pollution sources and stopping them at the source (see photo below)
raising the top of a building’s downspout just a couple inches so that rainwater can collect on the roof of the building and naturally evaporate rather then run down the downspout into the street
directing downspouts into plants, grass, or other vegetated areas
Check out this presentation created by Ana Mendiburu, a Reservoir Triangle resident, that summarizes what we learned on the stormwater walk:
Stormwater Walk Overview
(pdf)
Starting in November, members of our team reached out to businesses in the industrial park, many of which have been very receptive to our ideas about better managing stormwater runoff from their properties. We’re looking forward to working with them to improve their stormwater management practices, including a springtime tree planting among other projects. Stay tuned for more updates on this!

January 19th, 2013 – Residential Stormwater Workshop:
Neighborhood residents, City staff from the Parks Department and Office of Sustainability, among others, participated in a workshop to look at how individual residents could improve stormwater management at their homes and in the neighborhood as a whole.
Residents will begin meeting together to plan out springtime activities and outreach in the neighborhood to get more of their neighbors involved.
George Harvey co-led this workshop and prepared incredibly useful documents (see below) to help residents see tangible ways they could
prevent stormwater runoff from their homes, roofs, and lawns
. While a significant portion of the Reservoir Triangle neighborhood’s stormwater flows into the pond, especially from the homes right on the edge of the pond, much of the neighborhood’s stormwater goes into Combined Sewers (pipes where wastewater and stormwater combine) that are directed to Fields Point, the wastewater treatment facility off Allens Avenue. Ultimately all this treated water goes into Narragansett Bay. This still means stormwater can overburden the system and cost taxpayers and the City money — so figuring out ways to absorb more stormwater in the neighborhood will help a great deal.
Here are some photos of typical downspouts in Providence
– almost always letting out water from the roof onto concrete or some other non-absorbing material. Changing this can be easy though. We’ll be piloting some ideas in Reservoir Triangle this spring!

Here are some of the ways residents can help absorb more water coming off their roofs, lawns, and driveways.
The photos on the left are what it looks like in real life, and on the right each photo has been “doctored up” to show an example of a “BMP” – or a “best management practice” to better manage the stormwater. All renderings were prepared by George Harvey from Groundwork Providence:

May 4th, 2013 – De-paving Demonstration Project at 46 Crescent St.:
Reservoir Triangle resident, Laura Maxwell, volunteered her driveway to our project, allowing the Groundwork Providence green job training program to remove a layer of asphalt and about 6 inches of concrete from her driveway, replacing it with geoblock material and grass that will still allow her to drive across it to get to her garage but will absorb rain water coming off the roof of her house — helping reduce the stormwater load on Mashapaug Pond. Thanks Laura!
Check out these photos of the process:
The original asphalt driveway.
The end result: A grassy area that can absorb roof runoff and stormwater!
October 2013 – Right-of-Way Depaving and Planting:
Nellie Richardson and her family gave the EJ League the go-ahead to cut the concrete in front of their home on Algonquin St and create a planted buffer in its place. This was done with permission from the Providence Department of Public Works, with some materials donated by the Parks Department. The work was conducted by Groundwork Providence’s job training crew. Thanks everyone!
Check out the before and after photos:
The planted buffer captures roof runoff, filters pollutants, and prevents flooding on this street corner!
The EJ League is also working with businesses on the other side of Mashapaug Pond in the Huntington Business Park to implement stormwater solutions.
Ximedica, RI PBS, and Brown University’s Library Collections Annex all participated in a spring tree planting in 2013:
And we’ll be continuing this outreach in 2014!
The RI Department of Environmental Management, in collaboration with our project, was awarded $50,000 through a legal settlement against Southern Union (an oil/gas company that was found guilty of illegally storing mercury in an unlocked shack in Pawtucket). This money will go directly to support green infrastructure projects in the Huntington Business Park — and give Groundwork Providence’s job training graduates — GroundCorp — an opportunity for paid, on-the-job professional development. More details to come on this exciting development!
In the meantime, check out these upcoming events in May 2014:
Overview of our project:
While continuing to monitor and advance progress on
the cleanup of the former site of the Gorham Manufacturing Company
, which sits on Mashapaug Pond, the EJ League,
Groundwork Providence

Urban Pond Procession
are launching a new project that focuses on reducing stormwater runoff — the second major source of pollution for this almost 70-acre body of water.
Check out this presentation created by Will York, director of
smallFeat for Schools
and a project volunteer who lives in the watershed, about what stormwater is in the first place:

The main goals of our Mashapaug stormwater project are to:
Develop a core group of resident leaders to design and lead this project
Educate and engage residents and schoolchildren in the Reservoir Triangle neighborhood on ways they can contribute to the pond’s restoration through outreach, workshops, as well as hands-on trainings in basic stormwater management techniques led by
Groundwork Providence
Engage businesses in the Huntington Industrial Park located between Niantic Avenue and the pond, get commitments from them to reduce runoff from the business’s properties, and help them achieve these goals
Explore the potential to create jobs for Providence residents in the area of stormwater management and adding more green space to our city through innovative funding strategies
Urban stormwater runoff is a major source of pollution for all of our city’s waterways, including Mashapaug Pond, which creates unsafe conditions for people and ecosystems. Too much phosphorus from pet waste, fertilizers from people’s lawns, oil from the road, road salt, etc. wash into our waterways when it rains and contaminate them. In Mashapaug Pond, this process helps toxic bacterias develop that are a hazard to people and pets and reduce oxygen levels in the water, making it difficult for healthy plant and animal life to survive.
The solutions to this problem lie in eliminating these pollutants from runoff in the first place (picking up pet waste, not feeding geese or other birds, not using lawn fertilizers, ensuring motor oil is securely disposed of, etc) and increasing the amount of absorptive surfaces in our city — meaning increasing the amount of grass, plants, and trees, and reducing the amount of asphalt, concrete, and other surfaces that don’t absorb rain water.
Check out these
maps of Reservoir Triangle
created by George Harvey/Groundwork Providence that show
how much of the land us taken up by impervious surface
(meaning surfaces that don’t absorb water). Unfortunately this is all-too common all across Providence and is the biggest reason for polluted water quality in our city and state:

History of the UPP:
Artist Holly Ewald started the Mashapaug Pond Procession as a culminating public event in June 2008 after a several-month residency in local schools and community centers educating young people about the pond and creating silkscreen posters and fish costumes. The posters were then the inspiration for 4 new more pictoral signs with text translated in 3 languages warning pond visitors of the health hazards of the pond site. Eight new signs fabricated by the Department of Transportation are permanently in place around the pond.
The new signs placed around Mashapaug Pond.

WA Military Department Language Access needs

Summary: Equity tools, language map, language access map, census tract language map, 2016 data for languages by census tract

The Washington Emergency Management Division has
launched a new online map
to help local jurisdictions and the public at large figure out different languages spoken in counties and Census tracts across the state.
The goal is to help local governments know ahead of time what languages they need to have emergency messaging translated into before a disaster occurs. And, during a crisis, what languages may be in specific areas where something has happened – be it an earthquake, flood, wildfire or even a police event.
It’s state law for governments to provide life safety information in languages other than English if the limited English proficient population is five percent of the total population or 1,000 people, whichever is smaller.
“Having a map is a lot easier than an excel spreadsheet,” said Lewis Luján, the limited English proficiency coordinator for Washington Emergency Management Division. “It’s much easier to visualize.”
The map uses two data sets to determine language access. A “county” layer is based on 2016 population Office of Financial Management population data. There’s also “county subdivision” and “Census tract” layers based on 2015 Census information of languages spoken at home by a population, who is five years of age or older.
The map is color coded to provide details when one, two or more languages are spoken in that area. The Census tract allows the user to zoom into more specific areas to see the languages spoken in that specific area.
For instance, if an earthquake struck Spokane, you’d be able to see if the damage impacted a Census tract where residents spoke Russian in one part and Spanish in another.
“When the new Census comes out, we’ll take that data and update the map with the latest information,” said Rick Geittmann, the applications & database manager, who worked with Luján to create the map. “The goal is to make sure the map has the latest information available. This is a great way for you to visualize the data and be able to take – and see — how languages work spatially, so you can see where those people live and how we can better serve them.”
Meantime, Luján says he is working with local governments and other state agency partners to craft a cloud based- electronic database of pre-scripted messages in various languages. In addition, he’s working to credential speakers of various languages to provide immediate help in a crisis as well as teaming with the Washington National Guard’s own language experts to provide assistance.
“We have some way to go, but we’re making headway,” he said.

Washington Environmental Health Disparities Map

Summary: Washington State health dispariites map, environmental health disparities, census data to identify disparities, injury, disease, violence disparities, health outcome inequities, threat times vulnerability equals risk.

Environmental Health Disparities Map
About the Map
The Environmental Health Disparities (EHD) map is a collage of lived experiences across Washington. You, your families, and communities make up this map.
This interactive map compares communities using
census tracts
to identify
disparities
. Using the EHD map can help us determine where to place more attention to address and reduce the specific pollution, societal, and health harms affecting your life. Census tracts are small, relatively permanent geographic subdivisions within counties.
Census Tracts with Tribal lands are classified as “overburdened communities” or highly impacted. We should prioritize these communities and nations with resources and engagement.
Health disparities are preventable differences in the burden of disease, injury, violence, or opportunities to achieve greater health.
Concerns and needs of Washington residents are represented by showing combined impacts on their health.
A draft of the EHD map version 3.0 will launch in early 2026. The 3.0 version and future versions of the map will have more opportunities to engage and incorporate Tribal and community concerns.

What Are Environmental Health Disparities?
We define this as the increasing combination of factors (social, medical, climate, and environmental) that create inequities in health. These inequities, which cause more sickness, disease, pollution, and other problems for Washington communities with more economic need. Health disparities are the result of historical inequities from systems of oppression, such as racism and colonization.
For example, the map shows pollution measures such as
pesticide exposure
and
ozone concentration
, as well as
nearness to harmful waste sites
. In addition, the map can show a combination of impacts. For example, communities at the
federal poverty level
are at
greater risk for heart disease
While the EHD map cannot predict the future, it is a snapshot in time. The map helps us understand where we need to provide more financial support. The map also gives new and thoughtful insights into needs that we must prioritize to increase levels of health and wellness, so that everyone can benefit from clean air, clean water, and a healthy environment.
You Help Shape the Map
In creating the EHD map, we prioritized your voices, stories, and experiences. Our initial efforts to center your voices included listening sessions with communities across Washington. Many Washington residents shared experiences that informed the development of the map. We held follow-up sessions both in the community and through DOH Tribal relations. In 2024, a grant program awarded funds to communities and federally recognized Tribes. Additional similar funds will be released in 2026. Tribal and community engagement staff continue to support more robust Tribal and community engagement. Learn more about the
map’s development
If you have questions about using the map or want to share how you are using the map,
contact us
. We want to hear from you!
Video: How to Use the Map
We continue to add the instructional video in more languages based on your feedback. Please let us know if you would like this video in your language or a language used within your local community.
Use the EHD Map for Your Community Advocacy
The EHD Map is used to support several local, municipal, community, and government advocacy actions. Some of these are described in
Environmental Justice Assessment Notices
. Not all of the programs that use the EHD map have Environmental Justic Assessment Notices, so sometimes we are not aware of local and community actions informed by the map. To help us know more about how it is being used, please tell us how you use the EHD Map to inform change in Washington.
Just Like Math: Threat x Vulnerability = Risk
The EHD map is based on a formula of Risk = Threat x Vulnerability. Threat is made up of both environmental effects and exposures. Vulnerability is made up of socioeconomic factors and sensitive populations. In the image above, looking at the 25 topics (the measures for threat and vulnerability) together shows that living in areas with more threats (the green/left box) and things that make the population vulnerable (the blue/middle box) is related to a shorter lifespan or higher risk (the orange/right box). The threats are multiplied by socioeconomic factors and social vulnerabilities. Populations further away from the threats – in census tracts with the lowest environmental health disparities (rank 1) – on average live 8 years longer than those closer – in census tracts with the highest environmental health disparities (rank 10).
Learn more about the
data measures in the map
An Increase in Environmental Health Disparity Ranking Leads to a Shorter Life Expectancy
The bar graph shows the average life expectancy for people living in census tracts with each overall EHD rank. The y-axis shows life expectancy in years, and the x-axis shows overall EHD rank, from 1 to 10. A red horizontal line in the middle of the graph shows the state average life expectancy of 79 years. For each overall EHD rank, a blue bar going up or down from the red line (at 79 years state average) shows if the average life expectancy for that overall EHD rank is higher or lower than the state average.
The more health disparities you experience, the shorter your life expectancy will be.
