Chicopee Develops First-Ever Comprehensive Plan:
Envision Our Chicopee: 2040

news release

SANDWICH, Mass., December 4, 2023 – Horsley Witten Group, a full-service environmental consulting firm providing sustainable and resilient design solutions, has partnered with the City of Chicopee to develop its first-ever comprehensive plan. The community-driven plan, called Envision Our Chicopee: 2040, will guide the western Massachusetts city for the next two decades, and includes an actionable blueprint to achieve its community defined long-term vision for future growth and development.


Envision Our Chicopee: 2040 plan components include

  • brownfield redevelopment
  • zoning reform
  • land use and development
  • affordable housing
  • open space and recreation
  • historic preservation
  • public health, and transportation

“The beginning of a renaissance for the City of Chicopee, which is often referred to as ‘The Crossroads of New England,’ is underway and will continue for the next 20 years and beyond,” said Jeff Davis, Project Planner at Horsley Witten Group.

“Chicopee has conducted neighborhood-level planning in the past, but the time had come for a broader, comprehensive vision for the future of the city,” said Chicopee Director of Planning & Development Lee M. Pouliot. “Developing Envision Our Chicopee: 2040 was a remarkable opportunity to make the things we love about Chicopee even better and fix the things that need to be fixed over the course of the next 20 years. The plan prioritizes future investments in community services and infrastructure that promote fairness and equity throughout the city.”

Envision Our Chicopee: 2040 addresses several land development and socioeconomic issues affecting the former mill city that was built around distinct neighborhood centers, borders two rivers, and has significant transportation infrastructure including railways and major highway routes.

Developing resiliency solutions for the effects of climate change were included throughout the plan, as were initiatives to maintain a strong sense of diversity, equity and inclusion throughout the city, its facilities and services.

The final comprehensive plan is the culmination of a four-year effort that began in the summer of 2019 and continued throughout the COVID-19 pandemic. During that time, Horsley Witten Group worked with the Chicopee Department of Planning & Development and a Steering Committee established by former Mayor Richard Kosto to solicit feedback and input from city residents and community stakeholders. Due to pandemic restrictions, the typical planning activities and processes had to be adjusted and creative solutions implemented, including online and paper surveys, digital open houses, and use of a “meeting in a box” kit that enabled community members to lead their own small group meetings either in an outdoor setting during the warmer months, virtually or indoors according to state guidelines.

The Chicopee Planning Board unanimously approved the comprehensive plan in late September. “An immediate priority of the plan’s implementation will be a complete rewrite of the city’s zoning code, which hasn’t been substantially updated since 1974,” said Pouliot. “We need to be more creative with mixed-use development, infill development, address minimum parking standards, and consider the future of the exclusive single-family only Residential A District.”

In addition to Chicopee, Horsley Witten Group has participated in the long-term planning processes for more than a dozen New England municipalities, as well as communities in Arkansas, Hawaii, Maryland, and South Carolina. The Horsley Witten approach to comprehensive planning begins with compiling a complete inventory of existing conditions that serve as the foundation for analysis and public education. An engagement process is then initiated to determine and articulate a community’s values and priorities, culminating with an implementation plan that incorporates best practices, science, and innovation.

Lily pond park design wins award from ri-asla

HW News Release

Horsley Witten Group, a full-service environmental consulting firm providing sustainable and resilient design solutions, was honored with a regional American Society of Landscape Architects (ASLA) Merit Award-Planning and Analysis for the Lily Pond Park Master Plan on Nantucket.

ASLA Rhode Island presented the award to Horsley Witten, recognizing its vision for restoring the ecological and recreational function of the park, a 6.5‐acre property located within the residential outskirts of historic downtown Nantucket and owned by the Nantucket Land Bank.

Though the park itself encompasses only 6.5 acres, the plan presents a preferred approach to clean runoff from 90 acres of residential land surrounding the site using green stormwater infrastructure. In recent years, both the health of surrounding wetlands and park usage have been negatively impacted not only by unmanaged stormwater runoff, but also clogged drainage infrastructure, and invasive vegetation. The key design elements include a new looped boardwalk system over the restored wetland for improved accessibility, additional seating areas, park entrance enhancements, and restoration of a shallow marsh system. Constructed wetlands will be used to treat stormwater runoff coming into the park.

In granting the Merit Award, ASLA Rhode Island offered the following praise for the Horsley Witten Group, “The Lily Pond Park 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. Blending of the visitor experience with water quality and habitat enhancement and analyzing the site within its overall watershed makes the Lily Pond Park Plan a unique example of how we should be designing all sites within their larger ecological systems.”

The team completed the plan in August 2021. Since plan adoption, The Nantucket Land Bank secured a 2023 Southeast New England Program (SNEP) Stormwater and Natural Infrastructure Grant to help fund the construction and monitoring of proposed improvements. Due to the success of the Lily Pond Master Plan, the Nantucket Land Bank has also partnered with the town on a Stormwater Feasibility Study for Downtown Nantucket, using a similar planning approach. Advanced design development and permitting for the Lily Pond Improvements are expected to get underway in spring 2024.

“We are honored to receive recognition from ASLA Rhode Island for our work with the Nantucket Land Bank for the restoration of Lily Pond Park,” said Nathan Kelly, President, Horsley Witten Group. “Our talented team of landscape architects, engineers, and wetland biologists are proud to be closely aligned with ASLA’s mission to participate in the careful stewardship, wise planning, and artful design of cultural and natural environments.”

“We are grateful to be partnering with the Horsley Witten Group on the Lily Pond Park project,” said Jesse Belle, Executive Director of the Nantucket Land Bank. “Their master plan has provided us with an incredible opportunity to restore the wetland at this beloved public park, creating a space where both people and nature can interact and thrive. The project furthers the Land Bank’s goals of preserving scenic views, protecting ecological resources, and enhancing recreational experiences in nature for people to enjoy.”

SANDWICH, Mass., November 14, 2023 – Horsley Witten Group, a full-service environmental consulting firm providing sustainable and resilient environmental design solutions, has partnered with the Town of Mashpee, the Massachusetts In-Lieu Fee Program, and the Massachusetts Division of Ecological Restoration to restore the former Chop Chaque cranberry bogs to healthy, thriving wetlands similar to what they were prior to conversion to cranberry farming approximately a century ago.

There are two cranberry bogs at Chop Chaque totaling 6.5 acres that are situated on a nearly 12-acre town owned parcel of land adjacent to Santuit Pond. The cranberry bogs have been out of production for approximately four years.

Since cranberry cultivation has become more economically challenging in recent decades for farmers on Cape Cod, many have opted to retire bogs and place the land under conservation easement protection. Municipalities and other conservation entities that acquire the land or the conservation easement for these retired bogs often seek to restore them to something similar to the natural wetlands that existed prior to the conversion to cranberry agriculture and that will better support complex ecosystems and associated habitat. Ancillary benefits, such as improved nutrient management, are also often realized.


“It is a major trend and for good reason – restoring cranberry bogs to their natural state benefits the environment, encourages the return of wildlife and rare species habitats and contributes to the health of our waterways,” said Horsley Witten Group Principal Scientist Neal Price. With no restoration, intervention frequently fails to allow for recovery of wetlands systems with wetland functions and values similar to what would have existed prior to the original establishment of cranberry agriculture.”

The Chop Chaque project is being funded through a $525,000 In-Lieu Fee Program allocation from the Massachusetts Department of Fish & Game.  Horsley Witten Group was responsible for assessment of the Chop Chaque site, developing designs for restoration, which will include removal of the excess sand that had been added periodically over the decades of agriculture, filling artificial ditches, roughening bog services, removing a culvert that connects Santuit Pond to the bogs, and permitting of the project. Final design, construction, and post-project monitoring are still to come. Construction work on the Chop Chaque restoration project is expected to begin during the fall of 2024 and be completed in approximately two to three months.


“We look forward to once again working with Horsley Witten Group on this important ecological restoration project,” said Mashpee Conservation Agent Andrew McManus. “The organization and its team of talented and accomplished environmental scientists have worked with the Town of Mashpee on a wide range of projects including culvert replacement, dam repair and planning, and permitting processes.”

Horsley Witten Group has also managed or participated in other local cranberry bog restoration projects in Mashpee, Falmouth, Marstons Mills, Plymouth, and Yarmouth.
