The Woburn Conservation Commission closed a continued public hearing for Crescent Park roadway, walkway and parking resurfacing at 269–273 Cambridge Road (DEP file 348-890), after the civil engineer updated the commission on revisions requested at the prior meeting.

Jacob Murray of Waterfield Design Group told the commission the project is resurfacing existing roadway, walkways and parking and includes minor grading and curb replacement to address low spots that have caused puddling. Murray said none of the paving work is inside wetlands but much of the site is within the 100‑foot wetland buffer and riverfront area for Sucker Brook, so stormwater controls were a principal focus of the review.

The nut graf: commissioners pressed for verification that existing drainage structures are functional and instructed the applicant to clean basins and provide video inspection of outfalls so the commission can confirm whether additional repairs would trigger a new Notice of Intent rather than a minor plan change.

Murray reported the survey and inspection requests had been completed: catch basins and manholes were found generally in good condition but contained debris and only 2–3 feet of sump (new construction commonly requires about 4 feet). Several “catch basins” were functioning as dry wells that infiltrate to ground. The applicant added two proprietary separators (labeled PS1 and PS2 on the plans) to treat runoff: PS1 will treat about 18,000 square feet of impervious area (three upstream catch basins) and PS2 about 10,000 square feet (two upstream catch basins). The stormwater report was updated to list the site as a land use with higher potential pollutant loads and to reflect the proprietary units.

Commissioners asked why final video inspection of outfall pipes and any pipe repairs could not be completed before issuing an Order of Conditions. One commissioner warned that if video shows broken pipe that requires replacement, that could necessitate a new Notice of Intent rather than a minor revision. The applicant agreed to clean catch basins and to provide video of outfalls and asked that the commission review the videos prior to construction so the scope of any required repairs can be determined and included in construction documents if needed.

Other details discussed: snow storage will be in the far corner of the main parking area, furthest from resource areas; proprietary separators were placed outside catch basins to gather flow from multiple structures; applicants noted several catch basins act as infiltration devices and will be cleaned prior to construction.

At the close of the public hearing the commission voted to close the hearing on the Crescent Park repaving matter. The motion passed with 4 members in favor and 2 abstentions on the recorded tally.

Ending: The commission closed the hearing subject to the applicant cleaning catch basins, submitting pipe-videotaping for commission review, and finalizing the stormwater report as revised.
