Green Aspects of a Pare Project highlighted on Boston.com

Post Written By:  Allen Orsi

Dam removal provides many ecological benefits, including eliminating barriers to fish, wildlife, and macro invertebrate migration (habitat connectivity); improving surface water quality by reducing water temperatures, increasing dissolved oxygen, and increasing nutrient load;  reducing sediment starved flow; and restoring the surrounding area to a more natural and complex environment.

While PARE’s geotechnical division completes many dam evaluations and designs for repairs to deficient dams, dam repair is not always the best option.  After evaluating the structurally unsafe Curtis Pond Dam in Middleton, MA, a decision was reached with the dam owner to pursue dam removal.  PARE was subcontracted by Kleinfelder and worked closely with the dam owner and other project partners to develop construction documents for removal of the dam and for developing environmental permits to complete the work.

The project included removal of the dam to provide an unrestricted stream channel in the vicinity of the dam, bank restoration including coir logs and live stakings along select sections of the restored stream channel, and preservation of historical mill machinery salvaged from the dam during demolition activities.
