Site Monitoring

Site monitoring incorporates on-site inspections for both private and City-owned properties, community outreach, partnership development, and reviewing proposals and construction plans for projects that could impact the water supply.  The Watershed Division regularly conducts site inspections, tracks progress in a database, and generates annual reports.

Construction Sites

CWD is notified of new construction in the watershed primarily through regulatory processes or on regular patrols.  Developers are required to file with the local Conservation commission when working in a water resource area, such as the CWD watershed.  For many watershed construction and/or redevelopment sites, management conditions are issued by local Conservation commission and other regulatory bodies governing long-term operation and maintenance.  These activities include, but are not necessarily limited to, regulatory inspection, maintenance and reporting regarding stormwater management systems, limits on deicing chemicals, fertilizers, or other turf management chemicals, and street sweeping.  Larger projects could trigger the Massachusetts Environmental Policy Act (MEPA), which involves a public review process including permit review, public hearings, pre-construction field meetings, and regular monitoring of construction progress.

Proper and continued site maintenance is critical to water supply resource protection. CWD involvement in these projects is crucial to ensure the following:

  • All parties involved are aware that they are working near a water supply;
  • No significant impacts on source water tributaries and reservoirs will occur as a result of these projects; and
  • Improvements to existing conditions will be implemented as a result of these projects.


Dam Inspections

The Massachusetts Department of Conservation and Recreation (DCR) Office of Dam Safety requires biannual inspections on both the Stony Brook and Hobbs Brook Reservoir dams.  Both dams are characterized as "Large", "High" hazard potential dams in "Fair" condition with no evidence of immediate instability.  Watershed Division staff regularly inspect dams for seepage, rodent burrows, and other maintenance-triggering cues and generate in-house summary reports.

Security and Enforcement

Two full time reservoir caretakers cover a seven-day-a-week shift for surveillance, security, facilities maintenance, and assistance with implementing the watershed protection plan.  Activities that the CWD has not been notified of through the regulatory process are usually discovered by the reservoir caretakers, thus insuring that the CWD is involved with various projects.
