Spatial Justice Fellowship Program
Jon Ford, P.E.

HW is proud to sponsor the Congress for the New Urbanism (CNU) New England Chapter  2021 Spatial Justice Fellowship program at the highest “Visionary” level!

CNU New England is a non-profit organization that supports public and private sector leaders, community activists, and multidisciplinary professionals dedicated to building stronger cities and towns through citizen-based participatory planning and design. 

The Spatial Justice program is designed to improve spatial justice outcomes in New England cities and towns while increasing the quality of our joint professions by making room for new and different voices. 

During the summer of 2021, the program paid living wages to support three aspiring young professionals of diverse backgrounds to take part in otherwise unpaid internships and complete independent research projects.


HW’s Jon Ford, P.E., CNU New England co-founder, past President, and current board member, served on the program’s core committee and as a mentor for Grecia White.  Grecia conducted research bringing visibility to issues women and minorities face as they move around cities, starting with a wait time assessment and safety audit along MBTA bus routes.


a Master Plan for Habitat, Stormwater, & Recreational Improvements

Nantucket land bank

Lily Pond Park wetland and boardwalk today. Inset: Geese in Lily Pond in the 1890’s

How often do you get the chance to restore the landscape, improve water quality, and reduce localized flooding?

Not often, but Lily Pond Park in the heart of historic Nantucket is one place where it could happen.  HW worked with the Nantucket Land Bank on a Master Plan to improve the hydrologic, ecological, and recreational function of the park, a 6.2-acre property located within the residential outskirts of the historic downtown.

Stormwater runoff from over 90 surrounding acres drains into the park’s existing wetlands before ultimately discharging to the Town’s drainage system and out to Children’s Beach. A watershed services workhorse, the quality of this wetland habitat has degraded over time due to stormwater runoff inputs, hydrologic changes, and an invasive species explosion.


It’s such a gem, tucked into a residential area, I’m excited about what it could be in the future.” 

-Anne Kitchell, HW Associate Principal, Senior Watershed Planner

The Master Plan presents a preferred approach to restore and diversify wetland habitats, treat runoff with green stormwater infrastructure, and enhance the user experience with improved connectivity and signage. Key features include looped boardwalk extensions, more seating areas and entrance enhancements, daylighting of the existing outlet drainpipe into a surface stream, and restoration of a shallow marsh system with open water pockets. Stormwater Best Management Practices (BMPs) along the park perimeter (constructed wetlands, bioswales, etc.) provide initial water quality treatment.

Constructed wetland and habitat restoration illustrations above

Proposed Plan:
The plan prepared for the Nantucket Land Bank Commission includes priority invasive management areas, a phased implementation approach, and planning level construction costs plus contingency. The phases of construction are based on site constraints and staging feasibility include:

  1. Restoration of the central wetland and surrounding boardwalks and overlooks
  2. Restorative daylighting of the original stream
  3. Installation of a constructed wetland and entrance enhancements at North Liberty St.
  4. Construction of a cascading bioswale and constructed wetland with boardwalk at the existing Lily St. entrance
  5. Entrance improvements and upland amphitheater at 36 Lily acquisition

Example precedent images (left to right) of open water portion of a restored wetland, restored surface stream, constructed wetland, and cascading bioswale

Project Benefits:

  • Water quality – twice as much sediment removal and 1.5 times nutrient reduction over existing conditions
  • Flood management—by lower ponding elevations and shortening of inundation periods in the park and adjacent properties
  • Habitat enhancement—restoring diversity of wetland and stream habitats and controlling invasive plants
  • Improved visitor experience—enhanced park entrances, additional seating, more programmable upland areas, and looping boardwalks

Next Steps:
There is still much to be done including discussions with permitting agencies, DPW, and neighbors. We look forward to working with the Nantucket Land Bank and others moving forward on soil evaluations and water level monitoring, advancing restoration designs, and permitting.

Roger Williams park

Providence, RI

The Rain Harvest Arts Festival at Roger Williams Park encouraged visitors to celebrate water, science, and art – just our kind of party!  Hosted by the Providence Stormwater Innovation Center in June, the festival was a community celebration of the City of Providence’s investment in over 40 projects to clean polluted stormwater runoff before it enters the Park’s beloved ponds. Visual and performance artists and environmental scientists shared their inspirations and engaged the public in learning about stormwater and water quality. 

HW sponsored and participated in the festival, leading tours showcasing our stormwater projects throughout the park. The day was full of art, music, yoga, food, science, and great conversations about water!

We enjoyed the tours and look forward to future work at the park! Enjoy the short video by Big Tree Production.



“As a manual for implementation this submission is very user friendly and does an excellent job of communicating to its intended audience.

BSLA Jury comments


About the BSLA Design Awards Program

Boston Society of Landscape Architects (BSLA) seeks to recognize excellence in the diverse practices of landscape architecture. Projects should demonstrate excellence and reflect the careful stewardship, wise planning, and artful design of our cultural and natural environment. Awards may be granted in LANDMARK, PROFESSIONAL, and STUDENT categories, for design, analysis & planning, communication, and research projects. 

GSI Design & Implementation Guide Wins BSLA Award

The Boston Society of Landscape Architects (BSLA) has awarded HW with a Professional Merit Award in Communications for the Green Stormwater Infrastructure Design and Implementation Guide  created for Boston Parks and Recreation Department (BPRD).

Congratulations to everyone who worked on this Guide!  HW and our teaming partner, Brown, Richardson + Rowe, are honored to have collaborated with BPRD on the creation of the Guide.  This team effort included invaluable contributions from the Boston Water and Sewer Commission and the Trust for Public Land.

As climate change introduces new constraints and threats to Boston, resiliency has been identified as a city-wide goal.  BPRD is looking to advance the implementation of Green Stormwater Infrastructure (GSI) strategies to meet resiliency, livability, and health goals.  The Guide is intended to assist BPRD staff, as well as city agencies and consultants, to design, implement and maintain resilient, multi-functional parks that maximize benefits to park users and the environment.

The Guide includes distinctive key steps:

  • Defining and redefining GSI objectives with BPRD staff, partners, stakeholders, and volunteers throughout the project
  • Identifying the park contexts to understand all uses, allowing the layering of functionality and integrating, instead of inserting GSI into the park
  • Understanding and addressing maintenance requirements, expectations, and capabilities during the design process
  • Leveraging partnerships which can lead to additional funding for design and construction as well as shared resources and maintenance capabilities

View an example of a practice page from the Guide outlining considerations for designing GSI in parks.
