Vaughan Mall Green Presentation on Video

VMG Action Plan and Implementation Update Coming Soon

Planner and permaculture advocate Steve Whitman walked an audience of 60+ through the principles of permaculture, an approach to sustainable design, during the April presentation at 3S Artspace.

Whitman followed that up by facilitating an workshop at Discover Portsmouth that focusing on permaculture and place-making ideas specifically for the Vaughan Mall.  The results of that workshop and outcome of discussions with the City  will be online soon. Then PS21 and volunteers will be working with the City of Portsmouth to implement ideas over the next few weeks.



PS21 Events in April & May to Create Inviting, Ecological Common Space for Vaughan Mall

Growing out of a recent exploration of how to create dynamic, attractive public spaces, PS21 is sponsoring a three-part event in April and May to add ecological design and permaculture elements to Portsmouth’s downtown Vaughan Mall.

The Vaughan Mall area, between Congress and Hanover streets, was identified in recent PS21 placemaking events as a priority for improvement. This project, Vaughan Mall Green, will combine placemaking with a demonstration of the mall as an environmentally resilient civic space, reflecting Portsmouth’s designation as an eco-municipality. The principles of permaculture, a system of agricultural and social design elements intended to be sustainable and self-sufficient, will be incorporated in the area with the guidance of planner and designer Steve Whitman.

There are three parts to the Vaughan Mall Green project, whose goal is in part to increase pedestrian activity and make it more welcoming. In the mix are plans to add edible landscaping, native species and other plantings that aid in the absorption of rain and stormwater runoff.  Placemaking ideas developed at previous PS21 events include varied seating options, additional lighting, signs for pedestrians, live performances and other activities.

Volunteers, businesses, and gardening and sustainability-focused groups will assist in the design and implementation of Vaughan Mall Green. Please RSVP

Scheduled events include:

  • Thursday, April 20 at 7 PM at 3S Artspace – Presentation by planner and permaculture designer Steve Whitman of Plymouth. Learn how you can use an ecological design process for your own property or in creating positive changes elsewhere in the city. Whitman owns Resilience Planning and Design, and teaches at Plymouth State University and Colby-Sawyer College. Please RSVP
  • Saturday, April 22 (Earth Day) at Discover Portsmouth Center, 10 AM to 4 PM – Workshop on permaculture in an urban space and project development, led by Steve Whitman. Please RSVP
  • Saturday, May 13, Kick-Off of Design Implementation at Vaughan Mall – PS21 will partner with volunteers and the city to implement the design.

The City of Portsmouth, as part of its planning process, also is considering ways to enhance Vaughan Mall and nearby areas. While these plans may be informed by PS21’s Vaughan Mall Green project, they are separate efforts. PS21 (Portsmouth Smart Growth for the 21st Century) is an independent, all-volunteer nonprofit group.

This is the latest PS21 event to focus on planning and policy issues affecting the city and its residents. Please sign up at to help ensure sufficient space and to assist with planning. PS21 events are free and open to the public, and presented as part of its mission to stimulate discussion about planning issues affecting Portsmouth. PS21 is a 501(c)(3) nonprofit, and tax-deductible donations to support these free events are welcome.

Place-making: The Results Are In

Which location would you target first if you wanted to make downtown Portsmouth a better place?

After hearing ideas and seeing illustrations by landscape architect Robert White , there was a clear audience preference at a PS21 event: the Vaughan Mall.

More than 70 people attended the presentation and discussion at the library Feb. 1. The vote tally (estimated by PS21) was:

  • Vaughan Mall ~50%
  • ‘Spring Hill Square’ (Hanover and Market streets) ~ 35%
  • State Street – 10%
  • Market Square ~ 5%

Vaughan Mall supporters cited the need to improve the pedestrian walkway and the ease and relatively low cost with which it might be done.

The Feb. 1 session was a follow-up to PS21’s fall workshop on “place-making.” Place-making is a philosophy and approach to creating better public spaces that focuses: uses and activities, access and linkages, sociability and comfort and image. From the workshop, ideas for the Vaughan Mall, ideas included

  • Add a children’s play area
  • Provide more seating and a variety of seating options
  • Add a water feature
  • Bring back the stage
  • Consider expanding into the Worth Parking Lot
  • Provide better wayfinding for pedestrians and cyclists
  • Offer better lighting
  • Vary walking surfaces and textures
  • Improve maintenance of facades and storefronts
  • Add more vegetation

ADU Event Draws Full House

Nearly 90 people came to the Portsmouth library Feb. 22 to hear Ben Frost of the NH Housing Finance Authority and Rick Taintor, Portsmouth planning director, discuss accessory dwelling units (ADUs) and the city’s new ordinance governing ADUs.

The video includes both presentations and the Q&A afterward. Slides from Frost’s entertaining presentation on ADUs and the state law and Taintor’s detailed look at Portsmouth’s ordinance can be downloaded by clicking on the links. Portsmouth’s zoning changes also are available.

Accessory Dwelling Units in Portsmouth: What, Why & How

PS21 Event February 22 at Portsmouth Library to Learn More About the Possibilities and Impacts of ADUs

Are you wondering how the new Portsmouth Accessory Dwelling Unit ordinance could impact you and your neighborhood?

On Wednesday, February 22 at 7 PM in the Levenson Room of Portsmouth Public Library, PS21 will present an event featuring Ben Frost from the New Hampshire Housing Finance Authority and Rick Taintor from the Portsmouth Planning Department to discuss the law, its possibilities and impact.

New Hampshire’s Accessory Dwelling Unit (ADU) law was signed last year by Governor Hassan. An “accessory dwelling unit” is defined as a residential living unit that is within or attached to a single-family dwelling, and that provides independent living facilities for one or more persons.

The fundamental requirement of the new law is that every municipality with a zoning ordinance “shall allow accessory dwelling units as a matter of right or by either conditional use permit….” To comply with the ADU law, which takes effect statewide in June, the Portsmouth City Council passed an ordinance last month.

Frost of New Hampshire Housing will talk about ADUs, show examples, and explain how they can help ease the affordable housing crisis in the city and state.

Portsmouth Planning Director Rick Taintor will follow with a discussion of Portsmouth’s new ADU ordinance, and there will be an opportunity to ask him questions.

This PS21 event is free and open to the public, and presented by Portsmouth Smart Growth for the 21st Century (PS21) as part of its series to stimulate discussion about policy and planning issues affecting Portsmouth.

Adding Appeal to Portsmouth Public Spaces


Discussion at Portsmouth Library to Identify Locations and Priorities for Placemaking Project

We love Portsmouth, but there are still many ways to make our city even more appealing and walkable. On Wednesday, February 1 at 7 PM in the Portsmouth Public Library’s Levenson Room, PS21 with the assistance of landscape architect Robert White will lead a discussion on potential changes to four locations in the city: Market Square, Vaughan Mall, State Street and “Fat Belly Square” (the intersection of Market and Bow streets).

The event is the third PS21 event to focus on “placemaking” as a way to enhance walkability, retail life, traffic flow and social interaction. Last fall, PS21 sponsored a film and then a workshop on placemaking and how locations can be reinvented as unique and more appealing public spaces.

To follow up the fall sessions, Robert White will bring illustrations showing how Vaughn Mall, Market Square, State Street and Market Street might be transformed by some of the ideas generated. PS21 will lead a discussion, and participants will decide how to prioritize the suggestions and move forward.

Noted New England planner Jane Lafleur led the workshop last fall. She described placemaking as a process with community-based participation at its center, which capitalizes on a community’s assets, inspiration and potential, and results in the creation of quality public spaces that contribute to people’s health, happiness and well-being.

“Everyone has favorite places in the downtown area,” said Doug Roberts, chair of the volunteer group Portsmouth Smart Growth for the 21st Century (PS21). “Placemaking helps us learn why these places are pleasing, and how we can replicate their appeal.”

Please sign up at to help ensure sufficient seating. This event is free and open to the public, and presented by PS21 as part of its series to stimulate discussion about policy and planning issues affecting Portsmouth.

Save the date for the next PS21 event: Accessory Dwelling Units: What Are They and Why Build Them

Wednesday, February 22 at 7 PM at Portsmouth Public Library’s Levenson Room.

Ben Frost of the New Hampshire Housing Finance Authority will talk about ADUs and affordable housing in the state, and Rick Taintor from Portsmouth’s Planning Department will explain the ADU ordinance recently passed by City Council.

Islington Street Update & Happy Holidays

What’s Happening with Islington Street?

Islington Street crosswalk being removed

  • Portsmouth’s Parking & Traffic Safety Committee is expected to hear an analysis of the City’s two-month-long pilot project on Jan. 5.  Transportation Engineer Eric Eby told the PTS in December that a preliminary review suggests the bumpout and crosswalk made the street safer for both motorists and pedestrians.(UPDATE: Eby said the final evaluation report has been delayed and now will likely be presented in February.)

    (UPDATE OF UPDATE: A further pilot project to test the crosswalk will be done by the City in June, July and August per vote of the parking and traffic committee in February.)

  • Two images of Islington Street are featured prominently in a cheeky WIRED article on tactical urbanism.
  • Mike Lydon’s new book, The Tactical Urbanist’s Guide to Materials, uses Islington Street as a case study. (Page 96. The guide is impossible to read online. Look for the download.)

PS21 Report on Place-Making in Portsmouth

According to participants in a PS21 workshop, inexpensive measures like better seating, food trucks, planned activities, better lighting and basic landscaping could transform under-utilized spaces in downtown Portsmouth and enhance popular locations.

More than 40 citizens took part in ‘walkability audit’ and ‘place-making’ workshop in late October that focused on four downtown Portsmouth locations:

  • Vaughan Mall
  • Fat Belly Square (aka Market and Hanover streets)
  • Market Square
  • State Street (main between the Unitarian Church and Fleet Street)

Participants asked: Were the places welcoming, cooperative and neighborly? Did they have vital uses and enjoyable activities? Were the locations walkable, convenient and accessible? Were they safe, clean and attractive?

Ideas from the brainstorming session and the ‘place-making’ principles that informed it are summarized in a newly released report from PS21 (Portsmouth Smart Growth for the 21st Century) and Jane Lafleur, the workshop leader from the organization Lift360.


The workshop, which followed a showing of the classic film on place-making, “The Social Life of Small Urban Spaces,” generated dozens of ideas for enhancing downtown locations. PS21 plans a public session in January to discuss ideas.

ADU Ordinance Heads to City Council

An ordinance allowing accessory dwelling units (ADUs), as required by a recently passed state law, goes to the Portsmouth City Council on Dec. 5. The proposed ordinance can found on
