General Comments
Tide gate has been left open to aid in salt marsh restoration. Early signs of restoration were observed, including large die offs of phragmites, stunted phragmites growth and regrowth of low marsh species. High marsh has yet too rebound. Large unvegetated mud flats may revegetate over time but supplemental replantings may help to avoid further deterioration of peat layer. Die offs may be result of undersized culvert that is retaining too much water at low tide.Habitat Transects

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

Notes & Comments
- General Comments
- According to Ed Reiner: For the specific tide gate at the Central County Ditch in Revere, I believe that there is no specific control elevations or tide gate controls specified in any federal or state permit. The Corps at the time facilitated the replacement of broken tide gates with the SRT, where the landowner contributed money to the City of Revere to fund replacing the tide gate with an SRT. This agreement rectified the outstanding non-compliance where the Corps had acknowledged areas of replacement wetlands left too high to support wetlands in the grading plans. Water levels near 2.0 NGVD, (1.2 NAVD) would likely be needed to allow for Phragmites control. A gage exists in the creek which years ago was only showing high tide water levels only at 1.2 NAVD (0.4 NAVD). The lack of use of a bottom float has likely decreased the tides as the SRT closes with hydraulic force of an incoming tide which is not how the unit was intended to work.
