City to Observe Environmental Action Events This Spring

March 28, 2024

The City of Portsmouth declared itself an Eco-Municipality in 2007. Since then, it has taken steps to improve the environment in areas under the City’s direct control. In addition, it has encouraged private property owners, who control 71 percent of land within the City, to take steps to mitigate hazards to the environment. The City’s Planning & Sustainability Department is currently completing a Climate Action Plan, a key part of the forthcoming Citywide Master Plan, which has engaged the community in order to frame Portsmouth’s Climate Future.

April is traditionally the month for celebrating environmental action, particularly since the creation of Earth Day on April 22, 1970. Events are planned throughout the month to inform the public of the steps they can take to help.

Household Hazardous Waste Collection Day – On Saturday, April 13, 2024 between 8 am and 12 noon the Department of Public Works (DPW) will hold its biannual Household Hazardous Waste Collection Day at the Public Works facility at 680 Peverly Hill Road. Residents of Portsmouth, Greenland, and Newington are encouraged to bring household chemicals for safe disposal. Household hazardous waste collection helps safely dispose of items that can harm residents' health, the environment, and drinking water supplies. Proof of residency is required. Collection Day is organized as a drive-through service. Residents stay in their vehicles and pull through the Public Works garage, where staff will remove the disposable items. Residents will be asked verbally about their town of residence for survey purposes, in compliance with EPA requirements. For details of what items are accepted and which are not, visit:

Arbor Day – On Friday, April 26, 2024 at 8:30 am the DPW Parks and Greenery Division hosts its annual celebration of Arbor Day with tree planting and reading of the Mayor’s Arbor Day Proclamation. The Arbor Day Foundation has honored the City of Portsmouth with its Tree City Award for more than 20 consecutive years and also recognized its support of the urban forest with a Tree Growth Award. Founded in 1976, Tree City USA is a partnership between the Arbor Day Foundation, the U.S. Forest Service, and the National Association of State Foresters. The award results from meeting the program’s four requirements: a tree board or department, a tree-care ordinance, an annual community forestry budget of at least two dollars per capita, and an Arbor Day observance and proclamation. The Tree City USA Growth Award recognizes Portsmouth for demonstrating environmental improvement and a higher level of tree care. For more information, visit:
