Ecological Design

West Brittania, Taunton, MA

At the West Brittania dam removal project site, we teamed with Sum Co, Eco-Contracting, Inc. to implement design/build services for riverfront restoration and plantings along the Mill River for the Nature Conservancy. We coordinated with the Conservation Commission, designed the restoration area, and provided construction coordination and oversight.


Boston Public Schools, Boston, MA

In a truly rewarding project, we designed outdoor spaces with green stormwater infrastructure (GSI) to manage stormwater runoff and engage students at five Boston Public Schools. The GSI design incorporated various practices to help showcase methods for capturing, transporting, and cleaning stormwater. One component of this project was the integration of stormwater into the science curriculum. We created details in the outdoor classrooms to help students interact with the nature-based systems and monitor and test differences between practices. This project received an award in 2019 at the 25th Annual Secretary’s Awards for Excellence in Energy and Environmental Education.


Audubon Society of Rhode Island Nature Center, Bristol, RI

At the Audubon Society of Rhode Island, we designed a meandering, accessible path through an open meadow between the Visitor’s Center and the wetland boardwalk trail. To blend into the natural surroundings, we used a stabilized soil path that integrates stormwater and erosion control techniques to ensure the longevity of the path and the comfort of the users.


Norman Bird Sanctuary, Middletown, RI

HW created a comprehensive management plan for the Norman Bird Sanctuary (NBS) that identifies future investments and management opportunities for the property’s buildings, grounds, and environmental resources. We conducted field data collection on plant communities, trail conditions, drainage areas and cultural resources. We teamed with McLaughlin & Buie Housewrights, LLC to inventory building conditions. Working with NBS, we identified restoration opportunities and created an invasives species management plan within the historical and cultural context of the Sanctuary’s long-term vision. The project received an Honor Award for Planning and Analysis in 2019 from the RIASLA.

Connectivity Master Plans

Perkins Street Eco-Campus, Peabody, MA

Working with the City of Peabody and community stakeholders, we developed a comprehensive connectivity plan between Emerson Park and Scouting Woods to make the area a regional destination. This area includes various outdoor and indoor recreation areas, playgrounds, a middle school, a dog park and many acres of wetlands and woodlands. The plan gives priority to natural systems and pedestrians by restoring and conserving existing environments while developing safe and effective infrastructure, branding, and wayfinding.
