Revere, Townline Brook

Comments: Based on photos, it is unclear how many culverts are present at the site and what their dimensions are. A photo of the upstream end of the restriction shows that there are 15 metal trash grates installed at a concrete headwall while the tide gates are installed at the downstream headwall.

Comprehensive field assessment conducted in 2024

Upstream Invasive Species: Yes
Downstream Invasive Species: Yes
Invasive Species Notes: Phragmites mostly related to stormwater outlets and weeping hillside.
Additional Comments (2024): Upstream has been completely channelized with portions of reinforced bank all the way to the next upstream crossings. No upstream marsh exists due to steep channel banks except for small pockets along areas of more gradual bank. Downstream side inaccessible due to state highway.

Legacy data from previous surveys and documentation

General Comments: Site is located off of Route 1 to the northeast of the Showcase cinemas.
Gate Comments: There are three (3) metal self regulating tide gates (SRTs) installed at the site and an additional eight (8) conventional metal flap gates. The SRTs are located at the southernmost end of the headwall. The conventional metal flap gates are present for flood protection while the SRTs are installed to provide flood protection and restoration. Based on plans and photos it appears that the dimensions of the 3 SRT's are approximately 6' by 6'. Dimensions of the flap gates are unknown, but also appear to be on the order of 6' by 6'. As of 11/4/2015, the central SRT (Revere-08B) was missing the bottom float and not operational. Tidal leakage was also observed at and around the conventional flap gates.
