- Moderate
- Crab Burrow Intensity
- Limited (<10% banks are densely
- Ponding and Die-off Depressions
- Limited(<10% of marsh platform
- Phragmites Present
- Severe (>60%)

- Invasive Species Notes
- Large pockets of high marsh but otherwise phragmites.
General Comments
Tide gate appears to have been widened from 2 ft flapper in last inspection to 8 ft box with stop logs now. Upstream is mostly phragmites but only pockets of healthy mature phragmites exist near tide gate. Majority of phragmites is stressed, stunted and adjacent to high marsh pockets. May be an early indicator of restoration progress since redesign.Habitat Transects
First Transect (50 yards upstream of tide gate)
Second Transect (150 yards upstream of tide gate)
Third Transect (300 yards upstream of tide gate)
Restoration Potential
Assessment
- Salt Marsh Impairment due to Tidal Restriction
- Moderate
- Potential Extent of Marsh Restoration
- Moderate
- Implementation Feasibility
- High
- Restoration Priority
- High
- Recommended Improvement Type
- O&M and Infrastructure
Notes
Site shows moderate salt marsh impairment due to restricted tidal flow. Replacement with self-regulating tide gate could restore approximately 5-8 acres of degraded marsh habitat. Good access for construction equipment. Regional coordination completed with town DPW and conservation commission.Historical Records
Environmental Data
- Invasive Species
- Yes
- Restoration Status
- —
- Invasive Comments
- Some Phragmites observed both upstream and downstream, mostly along the edges of the salt marsh. Pattern may indicate freshwater runoff or septic fields.

- Upstream Area
- Total: 3.75, Salt Marsh: 0
Notes & Comments
- General Comments
- Bridge replacement occured from 2005-2008. Old flap gate has been removed and replaced with 3 horizontal wooden boards. Slight tidal restriction during high tides (potentially only for astronomically high tides).
- Operation Plan
- —
- Operation Comments
- No operating mechanism, appears to only be there for flood protection during abnormally high tides.
