We have an opportunity to work with—not against—our natural systems to protect habitats, infrastructure, and public health, and it’s our responsibility to ensure that everyone in the Watertown community can access and enjoy these benefits.
Watertown Open Space
Watertown has a variety of public open space for residents. From playgrounds and athletic fields to places to get out and take a walk or sit under a tree, we try to support many use types. The types of spaces are also important for how they serve our residents. Big parks are needed for recreation, but so are an even distribution of small areas for people to get outside no matter where they live.
Watertown has good park access on the southern side, but lacks neighborhood spaces in older neighborhoods to the north. Overall with our density we have far less space than is recommended for our residents. According to the Watertown Open Space and Recreation Plan, we currently have 3.7 acres per 1,000 residents whereas the National Recreation and Parks Association recommends 10.
Tree Canopy and Open Space
Watertown Tree Canopy
Trees bring important benefits to Watertown, like sequestering carbon, providing flood protection, habitat, and cooling, making them important assets as we adapt to climate changes in the region. Having the right amount of tree cover, for example, can lower summertime temperatures by as much as 10 degrees.
Did you know Watertown's trees are estimated to store 60,718 metric tons of carbon dioxide equivalent? That's a lot of carbon storage!

Benefits of Trees
In March 2021, the Town held the symposium called Trees and Climate Change in Watertown. Check out the slides and learn more from our speakers:

Our Tree Potential
Trees provide a wide range of benefits to the community and public street trees are especially important. Street trees contribute to the character of neighborhoods and keep streets and sidewalks shaded and cool for pedestrians.
We have room to grow when it comes to planting trees in public sites, such as along streets and sidewalks. By maximizing the number of the existing sites that are occupied with a tree, we can enjoy the many benefits that the tree canopy provides for us and make an investment in our community's future! In addition to filling these empty spots, it's important that we keep the trees we have already in good health.

Public Tree Health
Trees for Watertown and Teens for Trees help to assess the health of our public trees and work to enhance this community resource. The majority of our public trees are in good health which is sign. There is still work to be done as only half of the available places for a street tree are currently planted.
You can see more information about public trees on the Trees for Watertown Tree Map.

The City of Watertown Planted 162 trees during the Fall 2022 planting season! The map below provides details about location and species planted.
Native Plants and Pollinators
Native plants promote biodiversity, helping to keep our local ecosystems intact and thriving. They also are adapted to our local climate and weather, and therefore require less watering. Many native species are also excellent for pollinators, meaning they support a healthy bee population, which is in danger of decline.
In a signal of support for continued and expanded efforts to improve pollinator habitat in Watertown, City Manager George Proakis signed the Mayor's Monarch Pledge in spring 2023.
School and Community Gardens
One important way that we can promote nature-based landscaping in Watertown is by using school and community gardens as demonstration sites. These gardens can be spaces to learn about native plants, foster a sense of stewardship, and build community - all while enjoying the outdoors!
Our Plan has set targets to increase the amount of school and community garden space in Watertown to 24,000 square feet by 2030 and 30,000 square feet by 2050.

Watertown Land Cover
Watertown is a dense urban community with history as an industrial center. This has resulted in large areas of buildings and pavement. These impervious spaces make up nearly 57% of the land cover in Watertown.
As Watertown evolves we seek to build spaces that integrate greenspace and tree canopy throughout in order to reduce urban heat, intercept stormwater, and create restorative places for people. By shifting land use in our city, Watertown could accommodate 45 additional acres of tree cover - a 10% increase!
What is Stormwater?
Stormwater comes from rainfall and snow melt -- they sound so pure, don't they? But in a city like Watertown, not enough stormwater soaks into the ground, which would filter and clean the water. Instead, most of it flows across roofs, streets, and parking lots, and all along the way it washes litter, spills, dirt, and chemicals into our storm drains, which dump it straight into our ponds and the Charles River -- unfiltered.
In addition to challenges with water quality, with projected climate change, the volume of water that our infrastructure needs to handle will be strained. Watertown already maintains an extensive system for managing stormwater that includes:
- 3,200 catch basins
- 55 miles of drainage pipe
- 30 stormwater outfalls
What Is Green Infrastructure?
Green infrastructure is an approach to manage stormwater that relies on the natural way that water is filtered and absorbed by vegetation and soils. In an urban environment like Watertown, green infrastructure has many benefits including decreasing pollution to our waterways such as the Charles River, improving air quality, reducing urban heat, and adding beautiful green spaces to our streets.
To learn more, explore the map below of existing green infrastructure and read about the different types of green infrastructure you can see around Watertown!
The City has conducted an assessment to map areas of our community experiencing the urban heat island effect . As part of the Equitable Community Greening program, this assessment will help the City prioritize green infrastructure projects that will lower energy costs, minimize public health risks from extreme heat, and make our neighborhoods more livable.
Stormwater Advisory Committee
The Stormwater Advisory Committee acts as an advisory body to the Superintendent of Public Works. The Committee will:
- Develop educational programs and materials to increase public awareness of stormwater management.
- Identify and advocate for stormwater funding through grants and other sources.
- Review and make recommendations on stormwater ordinances and related regulations.
- Perform any other tasks relevant to assisting the Superintendent of Public Works with the implementation of best practices for stormwater management.
Normal meeting are held from 4:00 to 6:00 p.m. on the third Thursday of every month at the Department of Public Works Conference Room, 124 Orchard Street, Watertown. The public is welcome and encouraged to attend meetings.
What Can You Do
Add Your Own Green Infrastructure
Everyone can be a part of building a literally greener Watertown by investing in the green space that is right around their home. Planting in a bare place or taking care of the trees and other plants around you can improve your surroundings and that of your neighbors.
