The commission raised concerns about the project’s constraints, particularly the limited space for stockpile locations and dewatering areas, as the narrow site prevented these activities from occurring more than 50 feet from resource areas. The project manager clarified the work would mainly occur from Pleasant Street’s surface, with wetland areas on both sides complicating the situation. A temporary easement involving legislative approval was necessary to use protected park land, adding complexity to the timeline due to grant obligations requiring the project to be out to bid by September.

Discussions on dewatering plans highlighted the challenge posed by the lack of suitable upland areas, necessitating a plan subject to review by the Division of Marine Fisheries. The state would have a resident engineer on site for environmental monitoring, addressing concerns about regular inspections during construction.

The meeting also focused on the Massachusetts Division of Marine Fisheries’ time-of-year restrictions, which permitted work behind coffer dams during restricted periods. The commission discussed the project’s design compliance with MassDOT standards and the need for a hydraulic and scour analysis report recommending unsupported piling for abutment scour depth. Concerns about potential alterations to salt marshes due to riprap placement led to a commitment to minimizing impacts by adjusting the riprap limits.

Stormwater control measures were another focal point, with a seed mix proposed for road shoulders to assist in stormwater infiltration. Participants emphasized the importance of strict adherence to sedimentation and erosion controls, with the contractor required to follow specified guidelines.

In addition to the bridge project, the commission addressed several other topics. Notably, a debate arose concerning unauthorized alterations made to a property within a buffer zone. The work involved the use of rock riprap, which some argued was beneficial for wetland stabilization. However, the commission underscored that any unauthorized modifications could not set a precedent for future projects. A call for a field visit was made to assess the situation and determine necessary steps for issuing a certificate of compliance.

Financial and procedural matters were also on the agenda. The commission approved a budget amendment for a gas card. Discussions then shifted to the Wetland Protection Act filing fees, with a consensus to draft a letter to the board of selectmen requesting approval to use these funds for specific expenses like legal and consulting fees. A proposed bylaw amendment was discussed to allow fees collected under the Wetland Protection Act to be credited directly to the conservation fund rather than the general fund. This motion received unanimous support.

In another property-related matter, the commission heard from a resident concerned about property maintenance near old railroad tracks. The resident requested permission to relocate soil from the railroad area to their property. The commission emphasized the importance of soil testing for safety before any relocation, with assurances from the resident about handling potential contaminants appropriately.
