Mass Audubon Proposes Plan To Expand Pond and Create Ephemeral Pool at Pawtucket Farm

On July 16, 2025, the Lowell Conservation Commission convened to discuss significant amendments to a project aimed at enhancing stormwater management and ecological function at Pawtucket Farm. The meeting highlighted the proposal to expand the existing pond's footprint, introduce a new ephemeral pool, and resize a previously approved stormwater detention basin.

Liz Stetson, Senior Director of Capital Assets and Planning with Mass Audubon, opened the discussion by providing context for the proposed changes. The project, initially focused on surface water runoff, has evolved to address groundwater runoff, which has been identified as a contributing factor to flooding in adjacent farmland. Stetson emphasized the importance of managing both surface and groundwater to protect agricultural areas while also enhancing ecological diversity.

The proposed changes include expanding the pond's edge to create a gentler slope, which will support a wider variety of vegetation and provide habitat for amphibians and other wildlife. The introduction of an ephemeral pool is also intended to improve ecological function and offer educational opportunities for visitors. Additionally, the resizing of the stormwater detention basin aims to align with best practices for stormwater management while minimizing disruption to the natural landscape.

Jonathan Hedlund from Niche Engineering elaborated on the technical aspects of the stormwater management plan. He noted that recent soil testing revealed sandy soil types that would facilitate better stormwater infiltration, allowing for a reduction in the size of the proposed rainwater garden and minimizing the need for extensive earthworks. This adjustment is expected to meet both Massachusetts stormwater standards and local regulations.

The meeting also addressed questions regarding the nature of the ephemeral pool, which is designed to hold water temporarily, allowing for greater vegetation diversity without creating permanent standing water. The discussion underscored the project's dual focus on ecological enhancement and effective stormwater management, reflecting a commitment to sustainable practices in land use.

In conclusion, the Lowell Conservation Commission's meeting highlighted a proactive approach to environmental stewardship at Pawtucket Farm. The proposed amendments aim to create a more resilient ecosystem while addressing the practical challenges of stormwater management. As the project moves forward, it will be essential to monitor its impacts on both the environment and the surrounding agricultural community.
